Description

A rotating device and breast machine

technical field

The present application relates to an ultrasonic breast machine, in particular to a probe of an ultrasonic breast machine and a rotating device thereof.

Background technique

The probe of the ultrasound breast machine is large and heavy, and the doctor cannot hold the probe to scan the patient for a long time, so the probe needs to be hung on the support arm of the breast machine through the universal joint; the universal energy saving and flexible universal movement allows the probe to Scan flexibly. However, the related wires on the probe are all arranged along the inside or outside of the gimbal. When the gimbal rotates, these wires also rotate, which not only affects the life of the wires, but also often causes torsional fractures or other structural damages.

These institutions can only hope that when the doctor examines the patient, he can use his eyes to see the degree of twist of the exposed wire, or see whether some structures are faulty, and then actively stop the rotation of the universal joint, so as to avoid the wire. be twisted or cause other failures. Obviously, this distracts the doctor's attention, and it relies on human subjective judgment, which is unstable and unreliable, and cannot completely avoid risks; once the operator does not judge correctly, it will cause machine failure and so on.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Also, well-known functions and constructions will not be described in detail since they would obscure the description with unnecessary detail. In addition, the "connection" and "connection" mentioned in this application include direct and indirect connections (connections) unless otherwise specified.

In this embodiment, a rotating device is provided, referring to FIGS. 1-2 , including a rotating member 5 , a fixing member 4 , a connecting member 3 , a first limiting member 1 and a second limiting member 2 . The rotating member 5 is rotatable relative to the fixing member 4 , the connecting member 3 is fixedly connected to the rotating member 5 and the first limiting member 1 respectively, and the second limiting member 2 is opposite to the The fixing member 4 is fixedly arranged, the first limiting member 1 is rotatable relative to the second limiting member 2, and the second limiting member 2 forms a rotation limit for the first limiting member 1, In order to limit the rotation of the rotating member 5 relative to the fixing member 4; the connecting member 3 is a connecting member that can be bent and cannot be twisted, or a connecting member that can be bent and twisted at a certain angle. Among them, torsion is rotation along an axis.

The rotating device provided in this embodiment can be used in the mammography machine. When the user uses the mammography machine, the user will rotate the probe box to adjust it to an appropriate position and angle. At this time, the rotating member connected with the probe box will also rotate accordingly. Because the connecting part connected to the rotating part has the characteristics of being able to bend but not twist (ie 1:1 transmission) or the characteristics of being able to bend and twist at a certain angle (partially proportional transmission, that is, the transmission ratio is less than 1:1), so the The first limiting member fixedly connected by the connecting member will also rotate accordingly, and the second limiting member will form a rotation limit on the first limiting member, thereby restricting the rotation of the rotating member within a certain range. This can not only avoid the twisting and breaking of the inner and outer wires of the rotating part, but also avoid the collision between the large-volume parts (such as the probe box) fixedly connected on the rotating part and other parts when the rotating part rotates infinitely; Bit parts, etc. are hidden inside and do not affect the appearance. In addition, since the connecting part has the characteristic of being able to bend in addition to the characteristic of being incapable of being twisted or being able to be twisted at a certain angle, the rotating part can be guaranteed to swing within a certain cone angle range.

Axis X rotates. The swinging range of the rotating member 5 is determined by the bending performance of the connecting member 3 . When the connecting member 3 is a connecting member that can be bent and cannot be twisted, the rotation range of the rotating member 5 around the axis X is determined by the limiting range of the second limiting member 2 to the first limiting member 1 . When the connecting member 3 is a connecting member that can be bent and can be twisted at a certain angle, the rotation range of the rotating member 5 around the axis X is determined by the limiting range of the second limiting member 2 to the first limiting member 1 and the twisting range of the connecting member 3 decided together.
