Abstract
The utility model discloses a kind of endoscopic scissors, including dynamic spiral pin, push rod, fork, handle and fixed plate；Described dynamic spiral pin is made up of shears and pivot pin, and described shears has two, and two shears are rotationally connected by pivot pin intersection；One end of described push rod is connected by rivet is fixing with the tail end of shears, and the other end is rotationally connected by one end of pivot pin with fork, and the slide that the other end of fork is offered with handle one end by pivot pin is connected；Described fixed plate is arranged at fork, and fork is rotationally connected with fixed plate by hinge, and described hinge is arranged on the centre position of fork；Described push rod and fork are provided with two, and about symmetrical at the switching of two described shears.This endoscopic scissors is that movement range is minimum in operation, has the action expanded outwardly when only opening at scissors bit, effectively avoids its hetero-organization in patient body or the injury of trachea；Also alleviate burden for doctor simultaneously.
Description
Technical field
This utility model relates to medical apparatus and instruments applied technical field, is specially a kind of endoscopic scissors.
Background technology
Endoscopic scissors mainly uses under endoscopic surgery, primarily serves the purpose of shearing lesion tissue and unnecessary surrounding flesh
Meat, connective tissue etc..
It is to operate in patient body owing to using endoscopic scissors, so the operation amplitude of this kind of shears can not be too
Greatly, so as not to injury patient body in trachea or its hetero-organization；On market, existing endoscopic scissors is being designed without consideration
To this aspect, when doctor is when performing the operation, operate very inconvenient, bring the biggest misery to patient.
Summary of the invention
The purpose of this utility model is to provide a kind of endoscopic scissors, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, this utility model provides following technical scheme: a kind of endoscopic scissors, including dynamic spiral pin,
Push rod, fork, handle and fixed plate；Described dynamic spiral pin is made up of shears and pivot pin, and described shears has two, and two shears pass through
Pivot pin intersection is rotationally connected；One end of described push rod is connected by the tail end of rivet and shears is fixing, the other end pass through pivot pin and
One end of fork is rotationally connected, and the slide that the other end of fork is offered with handle one end by pivot pin is connected；Described fixing
Plate is arranged at fork, and fork is rotationally connected with fixed plate by hinge, and described hinge is arranged on the centre position of fork.
Further, described push rod and fork are provided with two, and about symmetrical at the switching of two shears.
Further, the work angle of described shears is 153 °.
Further, described shears includes scissors bit, a length of 11.23mm of described scissors bit, and height is 7mm.
Further, described push rod is the long column of an a length of 99.77mm, and width is 4.5mm, and height is 2mm.
Further, a length of 100mm of described handle.
Compared with prior art, the beneficial effects of the utility model are: this endoscopic scissors is movement range pole in operation
Little, there is the action expanded outwardly when only opening at scissors bit, effectively avoid its hetero-organization in patient body or trachea
Injury；Also alleviate burden for doctor simultaneously.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, a kind of embodiment that this utility model provides: a kind of endoscopic scissors, including dynamic spiral pin, push rod
2, fork 3, handle 4 and fixed plate 5；Described dynamic spiral pin is made up of shears 1 and pivot pin 6, and described shears 1 has two, two shears 1
Intersected by pivot pin 6 and be rotationally connected；One end of described push rod 2 is connected by rivet 8 is fixing with the tail end of shears 1, and the other end leads to
The one end crossing pivot pin 6 and fork 3 is rotationally connected, and the chute 41 that the other end of fork 3 is offered by pivot pin 6 and handle 4 one end is sliding
It is dynamically connected；Described fixed plate 5 is arranged at fork 3, and fork 3 is rotationally connected with fixed plate 5 by hinge 7, and described hinge 7 sets
Put the centre position at fork 3.
As optimisation technique scheme of the present utility model: described push rod 2 and fork 3 are provided with two, and about two
Symmetry at the switching of shears 1.
As optimisation technique scheme of the present utility model: the work angle of described shears 1 is 153 °.
As optimisation technique scheme of the present utility model: described shears 1 includes scissors bit, described scissors bit a length of
11.23mm, height is 7mm.
As optimisation technique scheme of the present utility model: described push rod 2 is the long column of an a length of 99.77mm, and width is
4.5mm, height is 2mm.
As optimisation technique scheme of the present utility model: a length of 100mm of described handle 4.
Operation principle: this endoscopic scissors action principle is to be perpendicular to handle 4 one active force, is driven by handle 4 and pushes away
Bar 2 and the motion of dynamic spiral pin, thus reach the cutting movement of apparatus scissor portion, it is achieved to lesion tissue and unnecessary surrounding flesh
The shearing of meat, connective tissue etc..
Handle 4 is similar to common scissors handle, a length of 100.00mm, and it is a chute 41 that handle connects push rod 2 part, sliding
Groove 41 bottom connects fixed plate 5, fixes push rod in chute 41 by hinge 7 and pivot pin 6.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
