Abstract

A minimally-invasive endoscope operating forcep head comprises a first forcep arm, a second forcep arm, a first pin shaft, a second pin shaft and a pulling-pushing shaft. The head of the first forcep arm is designed to be a first driven tooth piece. The head of the second forcep arm is designed to be a second driven tooth piece. The tail end of the pulling-pushing shaft is designed to be a driving rack. The first pin shaft and the second pin shaft are arranged on the base circle centers of the first driven tooth piece and the second driven tooth piece respectively. The head of the first forcep arm and the head of the second forcep arm are connected with the first pin shaft and the second pin shaft in a sleeved mode respectively. The first driven tooth piece and the second driven tooth piece are both meshed with the driving rack. According to the minimally-invasive endoscope operating forcep head, the direct proportion relationship between forcep opening clamping force and operation force can be achieved, an operator can sense and control magnitude of clamping force accurately, and operation safety is improved.

Description

Laparoscope pincers binding clip
Technical field
What the present invention relates to is a kind of operating forceps binding clip of Minimally Invasive Surgery instrument field, in particular a kind of laparoscope pincers binding clip of realizing linear mechanical relationship.
Background technology
Laparoscope pincers are operating theater instruments common in endoscope-assistant surgery, in order to clamp tissue in operation.The binding clip of the operating forceps using in open surgery utilizes the principle of lever, and the power on chucking power and handle presents linear relationship, so patient is easier to the size of perception chucking power, avoids overvoltage clamping.And due to the restriction of structure, the laparoscope pincers chucking power of binding clip presents non-linear relation with the size of operating physical force at present, make the patient cannot correctly perception chucking power size, easily cause the overvoltage to organizing to damage, and directly have influence on the success rate of operation.This problem is during laparoscope pincers use, to need the safety-critical problem of solution.
Find by prior art documents Chinese utility model patent application number: 200720023268.2, title: operating forceps, the inner surface of binding clip described in this patented technology has the anti-skidding striped parallel with binding clip opening direction.This structural reinforcing the non-skid property of pliers in organizing clamping process, but still cannot solve the tissue injury's problem causing because chucking power is excessive.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of novel laparoscope pincers binding clip is provided, make proportional routine relation between chucking power and operating physical force, make the size of patient's perception more accurately and control chucking power.
The present invention is achieved through the following technical solutions, the present invention includes the first tong arm, the second tong arm, the first bearing pin, the second bearing pin and push-pull shaft, the head design of the first tong arm is the first driven tooth part, the head design of the second tong arm is the second driven tooth part, the tip designs of push-pull shaft is active tooth bar, on the basic circle center of circle of the first driven tooth part and the second driven tooth part, be respectively equipped with the first bearing pin, the second bearing pin, the head of the head of the first tong arm and the second tong arm respectively with the first bearing pin, the second bearing pin socket, the first driven tooth part, the second driven tooth part is all meshed with active tooth bar.
Further, in the present invention, the first driven tooth part and the second driven tooth part all have cylindrical straight gear involute profile.
Further, in the present invention, initiatively tooth bar is spur rack.
Further, in the present invention, the first tong arm, the second tong arm, the first bearing pin and the equal symmetrical expression of the second bearing pin are distributed in the initiatively both sides of tooth bar.
In work process of the present invention, initiatively the engagement of tooth bar and driven tooth part is converted into rotatablely moving of two tong arms by the rectilinear motion of active tooth bar, by push-and-pull push-pull shaft, just can realize the switching of binding clip.On push-pull shaft, apply pulling force, its rectilinear motion is converted into the rotation of the first tong arm and the second tong arm by driven tooth part and the engagement of active tooth bar, thereby jaw is closed; Applied thrust on push-pull shaft, its rectilinear motion is converted into the rotation of the first tong arm and the second tong arm by driven tooth part and the engagement of active tooth bar, thereby jaw is opened.
Compared with prior art, the present invention has following beneficial effect: the present invention is reasonable in design, simple in structure, by quoting of gear & rack structure, can make chucking power and the proportional routine relation of operating physical force size, make the size of patient's perception more accurately and control chucking power, improve operation safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged diagram of A part-structure in Fig. 1;
Wherein: 1, the first tong arm, the 2, second tong arm, the 3, first bearing pin, the 4, second bearing pin, the 5, second driven tooth part, the 6, first driven tooth part, 7, tooth bar initiatively, 8, push-pull shaft.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, the present embodiment be take technical solution of the present invention as prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
embodiment
As shown in Figure 1 to Figure 2, the present invention includes the first tong arm 1, the second tong arm 2, the first bearing pin 3, the second bearing pin 4 and push-pull shaft 8, the head design of the first tong arm 1 is the first driven tooth part 6, the head design of the second tong arm 2 is the second driven tooth part 5, the tip designs of push-pull shaft 8 is active tooth bar 7, on the basic circle center of circle of the first driven tooth part 6 and the second driven tooth part 6, be respectively equipped with the first bearing pin 3, the second bearing pin 4, the head of the head of the first tong arm 1 and the second tong arm 2 respectively with the first bearing pin 3, the second bearing pin 4 sockets, the first driven tooth part 6, the second driven tooth part 5 is all meshed with active tooth bar 7, the first driven tooth part 6 and the second driven tooth part 5 all have cylindrical straight gear involute profile, initiatively tooth bar 7 is spur rack, the first tong arm 1, the second tong arm 2, the first bearing pin 3 and the equal symmetrical expression of the second bearing pin 4 are distributed in the initiatively both sides of tooth bar 7.
In work process of the present invention, initiatively tooth bar 7 is converted into rotatablely moving of two tong arms with the engagement of driven tooth part by the rectilinear motion of active tooth bar 7, by push-and-pull push-pull shaft 8, just can realize the switching of binding clip.On push-pull shaft 8, apply pulling force, its rectilinear motion is converted into the rotation of the first tong arm 1 and the second tong arm 2 by driven tooth part and the engagement of active tooth bar 7, thereby jaw is closed; Applied thrust on push-pull shaft 8, its rectilinear motion is converted into the rotation of the first tong arm 1 and the second tong arm 2 by driven tooth part and the engagement of active tooth bar 7, thereby jaw is opened.
