Description
Technical field
The present invention relates to area of medical devices, a kind of specifically electric coagulation forceps.
Background technology
Electric coagulation forceps is the important blood coagulation component in clinical surgery operation, and there are mainly two types of existing electric coagulation forceps, a kind of scissors
Formula, it is opened and closed using the effect control binding clip of scissors lever, one is pistol, are opened and closed by small of the stock remote control binding clip.
But existing electric coagulation forceps has the following disadvantages：
First, when in use, sometimes chucking power tension can then cause when in use, injury tissue；
Second, the structure of pistol is difficult to control operating aspect, especially is inconvenient to operate in Minimally Invasive Surgery.
Third, and it is scissor then since operating side and bare terminal end distance are too close, and the use in Minimally Invasive Surgery is limited
System.
Invention content
It is an object of the invention to：In view of the above problems, provide it is a kind of can far-end operation surgical operation coagulation
On the one hand pincers can buffer binding clip and the tension of tissue is clamped, on the other hand can increase the length of pincers pipe, can make coagulation
Pincers deeply into the human body, especially in laparoscope Minimally Invasive Surgery, carry out far-end operation blood coagulation, electric coagulation forceps disclosed by the invention point
It She You not following mechanism：
Binding clip, the binding clip and tissue contact, and blood coagulation operation is carried out, binding clip is connected with conducting wire；
Scissors handle, the scissors is for doctor's progress hand-held, opening and closing of the scissors control binding clip；
Pincers pipe, the pincers pipe is between scissors handle and binding clip, and both ends connect with binding clip and scissors fixed respectively
It connects；
Drive link, the drive link is connected between scissors handle and binding clip, and the rotation of scissors handle is passed to pincers
The opening and closing of head control binding clip, the drive link includes the third drive link and the second drive link being connect with binding clip, described
Third drive link be equipped with protrusion, the corresponding position of the second drive link is equipped with recess portion, and the depth of recess portion is more than protrusion, the end of protrusion
End is connected with the bottom end of recess portion by connecting spring, and when protrusion is stuck in recess portion completely, connecting spring is in tension；
Scissors described above two panels handle being made of, and the end of handle and drive link is equipped with connecting rod, connecting rod
Both ends are hinged with handle and drive link respectively, and when handle is transitioned into closure by opening, drive link is axially far from binding clip
The mobile control binding clip that carries out is closed.
In the process used, the protrusion of third drive link is stuck in the recess portion of the second drive link, at this time at spring
In tension, within the scope of a smaller power, rotating bar, third drive link and the second drive link is drawn not to relatively move,
When the chucking power of binding clip is very big, in the case of the pulling force of drive link is prodigious, third drive link and the second drive link have opposite shifting
It is dynamic, chucking power of the binding clip to skin can be reduced this when, prevent damage skin.
Of the invention simultaneously has abandoned traditional scissor electric coagulation forceps, and scissors handle is used using drive link, and in distal end
The movement of drive link is controlled to control binding clip, and with the difference of existing pistol, can be in conjunction with scissor and pistol
Advantage, and third drive link and the connection cooperation of the second drive link may be used, it on the one hand can be operated in distal end, on the other hand
Reduce caused damage excessive to the chucking power of tissue.
As an improvement, the drive link further includes with scissors the first drive link connecting, the first drive link and second
Drive link connects, and the first drive link and the second drive link can be rotated perpendicular to pincers pipe axial direction, and the proximal end for clamping pipe is equipped with and turns
Dynamic seat, a pair of of handle is hinged with rotation seat respectively, and the end for clamping pipe is equipped with the bulge loop for being located at pincers pipe periphery, and the inner wall of rotation seat is set
There are the concave ring groove coordinated with bulge loop, concave ring groove and bulge loop cooperation to allow rotation seat around pincers pipe axial rotation.
In existing technology, the direction of scissors handle is all fixed, and can not be rotated, and such case is sometimes outside
In section's operation, do not allow especially especially easy to operate in micro-wound surgical operation, especially operated to special part needs sometimes
Will be in suitable direction and position, and use scissors that rotary aspect is greatly facilitated the flexible operating of doctor, and
In the present invention, it needs to rotate rotation of the scissors drive link to be considered, that is, drive link and the small of the stock need Simultaneous Stabilization
Rotation, in order to solve these, drive link is divided into multistage by the present invention, can mutually be rotated between multistage, and in the outer of pincers pipe
Wall is equipped with can be relative to the rotation seat of pincers pipe rotation, rotation seat and scissors being hinged, and for the use of, control pincers pipe is not
It is dynamic, rotation seat is rotated, entire scissors is operated that can turn to accurate position with the drive link being connected.
As an improvement, the end of second drive link makes first equipped with the clamping portion for going deep into first drive link
Drive link and the second transmission can relatively rotate.
As an improvement, set on the second drive link there are one fixed seat and being socketed with resetting spring, one end of resetting spring and
Fixed seat connects, and the other end is connected with pincers pipe, and resetting spring enables under no outer force effect, and binding clip resets to opening shape
State.
The existing binding clip for cutting cutter handle structure key is restored to open configuration, then needs to open scissors handle with finger, this
When especially aspect operation, it is sometimes firmly much, influence surgical effect, to solve the above-mentioned problems, answered using above-mentioned
Position spring, when unclamping the external force of scissors handle, binding clip is then restored to deployed position, the operation of aspect surgical staff.
As an improvement, the binding clip includes the first binding clip, the second binding clip and binding clip seat, the second binding clip and the second binding clip point
Not and binding clip seat is hinged, and binding clip seat is fixedly connected with pincers pipe, and the end of the first binding clip and the second binding clip is equipped with mobile conduit, is moved
Dynamic conduit is connected with the pin connected with drive link, pulls drive link, the first binding clip and the second binding clip have the tendency that compressing in opposite directions.
Electric coagulation forceps disclosed by the invention has following projecting point：
One, electric coagulation forceps disclosed by the invention improves the length of pincers pipe by the operation of distal end, enabling more effectively deep
Enter portion into the human body and carry out blood coagulation operation, there is great application value in surgical operation；
Two, the drive link of electric coagulation forceps disclosed by the invention has the function of intelligent-induction, if the chucking power tension of binding clip,
The length of drive link can extend automatically, reduce damage of the chucking power of binding clip tension to tissue；
Three, the scissors of electric coagulation forceps disclosed by the invention as needed can rotate part, and doctor is worked as in surgical operation
When position is bad, it can be rotated as needed；
Four, the binding clip design of electric coagulation forceps disclosed by the invention can preferably control opening and closing, and tissue, existing binding clip is clamped
Majority has elasticity, it is difficult to clamp tissue.
