Detailed Description
The following description provides many different embodiments, or examples, for implementing different features of the invention. The elements and arrangements described in the following specific examples are presented for purposes of brevity and are provided only as examples and are not intended to limit the invention.
In the related art, the optical fiber bundle 310 is selected to replace the conventional traction rope, so that the optical fiber bundle 310 does not occupy the layout space in the active bending section of the insertion part, and the layout space of the instrument tube can be increased, but the optical fiber bundle 310 cannot be directly fixed by adopting the fixing mode of the conventional traction rope in order to avoid damaging the optical fiber bundle 310 due to the brittleness and the breakage of the optical fiber bundle 310.
The optical fiber bundle 310 is fixed on the traction component 110 of the linear traction mechanism by adopting the linear traction mechanism, the optical fiber bundle 310 moves along with the traction component 110 according to the fixed linear direction, so that the bending or straightening of the active bending section of the insertion part is realized, the proximal end of the optical fiber bundle 310 is connected with the related signal transceiver 320, wherein the signal transceiver 320 can be a light source box, a light source signal emitting device or a device for receiving information transmitted from the optical fiber bundle 310, the length of the optical fiber bundle 310 between the traction component 110 and the signal transceiver 320 is unchanged, but the distance between the traction component 110 and the signal transceiver 320 can be changed due to the fact that the traction component 110 needs to move, the fixed length of the optical fiber bundle 310 is arranged between the distances, and the optical fiber bundle 310 can bend or straighten along with the change of the distance due to the change of the distance, but the optical fiber bundle 310 belongs to a brittle and easily-bending phenomenon can easily occur after the optical fiber bundle 310 is bent randomly.
Thus, in some embodiments of the present application, the signal transceiver device 320 is selectively configured to move with the pulling member 110 to avoid changing the distance between the signal transceiver device 320 and the pulling member 110, and thus avoid bending or straightening the length of the optical fiber bundle 310 therebetween.
In the embodiments of the present application, "proximal" and "distal" refer to the endoscope and its accessories in the use environment, with respect to the user's near-far position, wherein the end closer to the user is designated as "proximal" and the end farther from the user is designated as "distal".
Embodiments of the present application are not limited to the specific type of the optical fiber bundle 310, for example, it may be an illumination optical fiber bundle 310 for conducting the light of the light source to the distal end side of the insertion portion, or it may be a photographing optical fiber bundle 310 for conducting the external light of the distal end side of the insertion portion back to the photographing module.
The technical scheme disclosed by each embodiment of the application is described in detail below with reference to the accompanying drawings.
Example 1
The embodiment provides a linear traction mechanism for an optical fiber bundle of an endoscope, which is shown in fig. 1 to 5, and comprises a driving assembly 100, a connecting sheet 200, a signal transceiver 320 and two groups of optical fiber bundles 310, wherein the driving assembly 100 is a linear driving mechanism commonly used in the technical field of endoscopes and comprises a transmission member 120 and two groups of traction members 110, the two traction members 110 are respectively positioned at two sides of the transmission member 120 and matched with the transmission member 120, the transmission member 120 is used for driving the two groups of traction members 110 to synchronously move in opposite directions, two ends of the connecting sheet 200 are bent towards the same side of the connecting sheet 200, one end of the connecting sheet 200 is fixedly connected with one of the two groups of traction members 110, the other end of the connecting sheet 200 is fixedly connected with the other end of the connecting sheet 200, the protruding direction of the connecting sheet 200 is deviated from the transmission member 120, when the traction members 110 move, the ends of the connecting sheet 200 also move, bending points of the connecting sheet 200 are changed, the two groups of optical fiber bundles 310 are arranged in one-to-one correspondence with the two groups of traction members 110, the proximal ends of the two groups of optical fiber bundles 310 are connected with the signal transceiver 320, the signal transceiver 320 are arranged on the surface of the connecting sheet 200, one side of the signal transceiver 320 is positioned between the signal transceiver 320 and the optical fiber bundle 110 and the optical fiber bundle 120 and the side of the optical fiber bundle 120.
The signal transceiver 320 is mounted on the connection piece 200, two ends of the connection piece 200 are respectively fixed with the traction part 110, when the traction part 110 is driven by the transmission part 120 to move synchronously and reversely, two ends of the connection piece 200 can also move along with the movement of the connection piece 200, therefore, the length of the connection piece 200 between the signal transceiver 320 and the traction part 110 can not be changed, correspondingly, during the movement of the traction part 110, the optical fiber bundle 310 connected between the signal transceiver 320 and the traction part 110 can not be pulled and damaged, meanwhile, the connection piece 200 can support the optical fiber bundle 310 between the signal transceiver 320 and the traction part 110, and in addition, because the connection piece 200 has a bending structure, when the optical fiber bundle 310 moves, the movement direction of the optical fiber bundle 310 can be limited, so that the optical fiber bundle 310 is bent according to the bending structure of the connection piece 200, the bending direction of the optical fiber bundle 310 can be prevented from being random, the connection piece 200 is generally selected to have a certain toughness, the optical fiber bundle 310 can be bent under the external force, and the opposite bending direction of the connection piece 200 can be kept relatively stable when the bending structure is opposite to the bending direction of the optical fiber bundle 200.
In particular, when the two traction members 110 are used, the moving directions of the two traction members 110 can be on a straight line, the included angle of the two moving directions is 180 degrees, or the two traction members are not on a straight line, and are slightly misplaced, the included angle of the two moving directions is smaller than 180 degrees, mainly for being matched with a narrow arrangement space in an endoscope handle 500, after the optical fiber bundle 310 is fixed on the traction members 110, the proximal ends of the optical fiber bundles 310 are connected with the signal transceiver 320, and in combination with the illustration of fig. 1, the two traction members 110 are both located at initial positions and do not move, at the moment, the signal transceiver 320 is located at the part of the bending structure of the connecting sheet 200 farthest from the transmission member 120, when the transmission member 120 is started, the traction members 110 move, as illustrated in fig. 2, one traction member 110 moves forward, and one traction member 110 moves backward, and the signal transceiver 320 mounted on the connecting sheet 200 moves accordingly.
The length of the connection piece 200 should be determined according to the moving range of the traction component 110 and the distance between the two traction components 110, when in use, the length of the connection piece 200 cannot be too short, mainly in order to maintain the stability of the bending structure of the connection piece 200, when the two ends of the connection piece 200 move along with the traction component 110, the bending point and the bending radian of the connection piece 200 can be maintained stable, the bending radian of the connection piece 200 cannot be changed too much, the phenomenon that the optical fiber bundle 310 cannot bend during bending is ensured, the shortest distance between the two ends of the connection piece 200 is used as the first distance, and the length of the connection piece 200 is larger than half of the circumference of a circle with the first distance as the diameter.
The signal transceiver 320 provided in this embodiment has three interfaces, namely, a first interface 321, a second interface 322 and a third interface 323, where the first interface 321 and the second interface 322 are used to connect with the optical fiber bundle 310, one interface corresponds to a group of optical fiber bundles 310, the third interface 323 is used to connect with the outside, when the signal transceiver 320 is a light source box, the third interface 323 is used as a power interface, and when the signal transceiver 320 receives information conducted from the optical fiber bundles 310, the third interface 323 is used as an interface for transmitting information with the outside.
Because the optical fiber bundle 310 moves along with the signal transceiver 320, and a certain bending occurs during the movement process to adapt to the bent connection piece 200, the connection structure of the optical fiber bundle 310 and the signal transceiver 320 is important, so that bending points of the optical fiber bundle 310, which may occur in the movement process, need to be reduced, in this embodiment, the axis of the first interface 321 and the axis of the second interface 322 are parallel and tangential to the connection piece 200, and the tangential position is located at the installation position of the signal transceiver 320 and the connection piece 200, so that when the optical fiber bundle 310 is connected with the signal transceiver 320, the optical fiber bundle 310 is connected along the length direction thereof, so as to reduce the bending probability of the optical fiber bundle 310, and preferably, the axis of the first interface 321 and the axis of the second interface 322 are arranged in a collinear manner, so that the positions of the optical fiber bundle 310 connected at two ends of the signal transceiver 320 are balanced, and the smoothness of the whole equipment is improved.
When the connection piece 200 moves, when the signal transceiver 320 moves to the bending and turning position of the connection piece 200, if the signal transceiver 320 is completely fixedly connected with the connection piece 200, the signal transceiver 320 will form a pulling between the signal transceiver 320 and the connection piece 200, which affects the smoothness of the whole equipment, in this embodiment, the signal transceiver 320 is rotationally connected with the connection piece 200 through the rotation shaft 410, and as shown in fig. 3 to 5, one of the signal transceiver 320 and the connection piece 200 is rotationally connected with the rotation shaft 410, and the other is fixedly or rotationally connected with the rotation shaft 410, the signal transceiver 320 uses the axis of the rotation shaft 410 as the rotation axis, and the rotation shaft 410 is arranged along the width direction of the connection piece 200, because the connection piece 200 is of the bending structure, when the signal transceiver 320 passes through the bending and turning point of the connection piece 200, the signal transceiver 320 can have a certain activity allowance when the pulling occurs between the connection piece 200 and the signal transceiver 320, and the position between the signal transceiver 320 can be automatically adjusted, thereby avoiding the pulling and improving the smoothness and stability of the whole equipment.
When the rotating shaft 410 is installed, the axial position of the rotating shaft 410 needs to be set along the width direction of the connecting piece 200, mainly to reduce the length of the connecting position of the signal transceiver 320 and the connecting piece 200, reduce the influence of the connecting piece 200 on the signal transceiver 320 when passing through the turning point, and ensure that the signal transceiver 320 and the connecting piece 200 are stably connected, and meanwhile, the smaller the diameter of the rotating shaft 410 is, the better the smaller the diameter of the connecting piece is.
Specifically, as shown in fig. 4 and 5, the connection structure between the signal transceiver 320 and the connection piece 200 is that a first connection block 420 is fixed on the surface of the signal transceiver 320, which is close to the connection piece 200, a second connection block 430 is arranged on the surface of the connection piece 200, which is away from the transmission piece 120, the rotation shaft 410 passes through the first connection block 420 and the second connection block 430 at the same time, the signal transceiver 320 can rotate around the axis of the rotation shaft 410, in one embodiment, as shown in fig. 4, a rotation gap is formed between the surface of the first connection block 420 and the surface of the connection piece 200, the signal transceiver 320 is not contacted with the surface of the connection piece 200 in the rotation process, and the rotation is smoother, in another embodiment, as shown in fig. 5, the surface of the first connection block 420, which is close to the connection piece 200, is an abutting portion 421, the abutting portion 421 is provided with a contact point, and the abutting portion 421 is arranged to bulge in the direction of the connection piece 200, and when the signal transceiver 320 rotates with the connection piece 200, the bulge portion is always contacted with the connection piece 200, so as to ensure the rotation of the signal transceiver 320.
In the drawings provided in this embodiment, for easy understanding and viewing, a certain gap exists between the optical fiber bundle 310 and the connection piece 200, and in practical implementation, the optical fiber bundle 310 is partially directly laid on the surface of the connection piece 200, and a limiting groove 210 may be disposed on the surface of the connection piece 200 facing away from the transmission piece 120, where the length direction of the limiting groove 210 is the same as the length direction of the connection piece 200, and the optical fiber bundle 310 is placed in the limiting groove 210, and is limited by the limiting groove 210, so that the optical fiber bundle 310 cannot move left and right.
When the traction mechanism of this embodiment is used, the traction component 110 may be divided into two parts, a fixed base 111 and a moving block 112, the fixed base 111 is fixed inside the handle of the endoscope, the moving block 112 is slidably connected with the fixed base 111, the optical fiber bundle 310 is fixedly connected with the moving block 112, the transmission member 120 is in a gear structure, the gear structure is meshed with the two moving blocks 112 at the same time, and the two moving blocks 112 move in opposite directions at the same speed along with the rotation of the gear structure.
