Description

A kind of non-rotatable foreskin Endo-GIA of bell jar

Technical field

The utility model relates to foreskin Endo-GIA technical field, especially a kind of non-rotatable foreskin cutting of bell jar Stapler.

Background technique

Pistol type foreskin Endo-GIA its trigger transmission device currently on the market is by transmission arm, main articulated shaft, swing The composition such as arm, driving member and trigger drives driving member to push transmission arm by trigger, and transmission arm pushes main articulated shaft, main hinged Axis drives transmission arm and swing arm, pushes sliding block and connecting shaft mobile by transmission arm, this mode structure is complex, and accessory is more Assemble complex, when use is easy stuck, and manufacturing cost is high.

Patent CN205307057U describes a kind of foreskin Endo-GIA, such as Fig. 1-2, and bell jar 18 is located at nail under normal conditions In storehouse set 2, protection cap 21 is equipped between nail storehouse sleeve 2 and bell jar 18, when in use, first to rotate adjusting nut 15 makes to be socketed in 14 synchronous rotary of copper nut therein will set threaded connecting shaft 19 and release, and stretch out bell jar 18 other than nail storehouse sleeve 2, destroy Protection cap, while by the outside the head 18-1 of phallic foreskin turnup to bell jar 18, and it is banded in the body of rod at 18 middle part of bell jar It on 18-2, then holds outside nail storehouse sleeve 2 on the other hand, rotating adjusting nut 15 on the other hand makes bell jar recycling (for preventing nail storehouse sleeve same Step rotation causes suffering to patient), it allows nail bin to be only butted on foreskin surface, then take away safety block 20, pulls the drive of flexible handle 9 and push away Motion block 5 and pushing slice of nail 3 fire the anastomosis staple in nail bin 4 and carry out foreskin suture, while pushing slice of nail 3 fires the kiss of pushing slice of nail inner cylinder side It closes cutter ring and carries out foreskin cutting.It will necessarily be to even when due to lacking the design for preventing nail storehouse sleeve from rotating, and rotating adjusting nut 15 Spindle 19, bell jar 18, pushing slice of nail 3, nail storehouse sleeve 2 apply torque, so in operation with manufacture accessory when it is cumbersome.

Utility model content

Utility model aims to solve the handle housing of foreskin Endo-GIA, nail storehouse sleeve, nails in the prior art The complex problem of chamber structure now provides a kind of non-rotatable foreskin Endo-GIA of bell jar, the Endo-GIA structure Simply, manufacturing cost is low, and accessory is easily worked.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of non-rotatable foreskin cutting of bell jar Stapler, including bell jar, trigger transmission mechanism, rotating nuts component are successively nested with installation using bell jar as core from inside to outside and push away Piece, nail storehouse sleeve, handle housing are followed closely, nail bin is located at the head end of the pushing slice of nail, and the tail end of the pushing slice of nail is equipped with pushing block, bell jar Tail end is equipped with tapped blind hole, and connecting rod one end passes through the threaded connection bell jar on surface, and the connecting rod other end protrudes into rotation spiral shell In female component, the connecting rod lower surface is equipped with a gap-like sliding slot, and described gap-like sliding slot axially extends to both ends along connecting rod； The trigger transmission mechanism includes flexible handle, and the flexible handle is rotatably installed on the handle housing, the movable hand Opened up on handle it is fluted, in the grooves portion be equipped with protrusion, groove two sides are the fin that outer profile is curved surface, and the connecting rod is worn The groove is crossed, when the relatively described handle housing of flexible handle is reset position, the protrusion is contacted to described gap-like sliding slot Interior, the bell jar for preventing rotating nuts component from connecting when rotating with connecting rod rotates synchronously.

By the way that a gap-like sliding slot is arranged in connecting rod lower surface in this programme, groove is opened up on flexible handle, in groove Middle part setting protrusion, after assembling foreskin Endo-GIA, the protrusion is contacted to the sliding slot, on the one hand prevents rotation The turn nut component rotating tendency of connecting rod and its bell jar of connection when rotated；On the other hand prevent rotating nuts component anti- When rotating adjusting bell jar stretching again with retracted position, the trend of connecting rod and blind hole loosening in bell jar.

Preferably, the lateral surface of the protrusion is arc surface, the center of circle of circumscribed circle and the activity where the arc surface Hinge joint eccentric setting between handle and handle housing, when the relatively described handle housing pulls flexible handle, the protrusion exists It linearly travels forward in the sliding slot.

It can be contacted to the sliding slot in the movable overall process protrusions of bell jar, even if in this process, it is unexpected Have rotated rotating nuts component, connecting rod and bell jar will not synchronous rotary, improve the safety of operation foreskin Endo-GIA Property.

Finally due to aforementioned advantage, effectively simplify the structure setting of pushing slice of nail, nail storehouse sleeve, handle housing, bell jar, drop Low accessory processing cost, specific as follows:

The bell jar tail end is cylinder, the bell jar and pushing slice of nail clearance fit.

The pushing slice of nail tail end sleeve is smooth annular body.

The beneficial effects of the utility model are: the foreskin Endo-GIA bell jar, pushing slice of nail, nail bin noose of the utility model Structure is simply without polymorphic structure, and easy processing, being contacted by protrusion with sliding slot can make connecting rod rotate through in rotating nuts component It is blocked in journey, safety when operating foreskin Endo-GIA.
