Abstract
The utility model relates to an in-position actuated protecting device for a disposable linear anastomat. The in-position actuated protecting device comprises a push-nail base, a supporting plate, an anastomosis component, a moving body and an adjusting nut, wherein the anastomosis component is mounted at the front end of the moving body, the moving body is movably mounted on the supporting plate, the push-nail base is mounted at the front end of the supporting plate, an insurance block is riveted on the lateral plate of the moving body through a rivet, a torsion spring is mounted on the rivet, one end of the torsion spring is propped against the moving body, the other end of the torsion spring is propped against the insurance block, a pin is mounted at the free end of the insurance block, and a lug boss corresponding to the pin is mounted on the supporting plate. By adopting the in-position actuated protecting device for the disposable linear anastomat, the actuation of instruments can be effectively controlled, so as to prevent operation failure.
Description
Technical field
This utility model relates to a kind of disposable use linear anastomat percussion safety that put in place, is used for abdominal surgery, thoracic surgery, gynecological and Pediatrics Department, and main uses is the stump and the otch of closed organ or tissue.
Background technology
Present disposable use linear anastomat mainly comprises nail supporting base parts and moving body part.The turn adjusting nut makes moving body drive assembly and moves to nail supporting base, reach certain zone after, the firing handle of just holding with a firm grip is released the nail bin surface to anastomosis staple until molding.Because general anastomat before percussion, all is to withstand between firing handle and the fixed handle by bumper bar, so just have the risk that bumper bar is midway opened, cause apparatus also not put in place with regard to pulling the trigger, cause operative failure.
Summary of the invention
The purpose of this utility model provides a kind of percussion of control device effectively, the disposable use linear anastomat that the prevents operative failure percussion safety that put in place.
The technical scheme that realizes above-mentioned purpose is: a kind of disposable use linear anastomat percussion safety that put in place, comprise nail supporting base, supporting plate, anastomotic component, moving body and adjusting nut, anastomotic component is installed in the front end of moving body, moving body is installed on the supporting plate movably, nail supporting base is installed in the front end of supporting plate, by rivet safety block is arranged on the side plate of moving body, torsion spring is installed on the rivet, one end of torsion spring is against on the moving body, the other end is against on the safety block, the safety block free end is equipped with pin, and the boss corresponding with this pin is installed on supporting plate.
After adopting technique scheme, by rivet safety block is arranged on the side plate of moving body, torsion spring is installed on the rivet, one end of torsion spring is against on the moving body, the other end is against on the safety block, the free end of safety block is equipped with pin, and the boss corresponding with this pin be installed on supporting plate, like this when moving body is adjusted to certain position, boss on the supporting plate will make safety block inoperative the pin on the safety block toward pressing down, and so just can pull the trigger, thereby the apparatus just phenomenon of percussion that also do not put in place can not occur, thereby can avoid the failure of performing the operation.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Shown in Fig. 1 ~ 3, a kind of disposable use linear anastomat percussion safety that put in place, comprise nail supporting base 4, supporting plate 5, anastomotic component 3, moving body 2 and adjusting nut 1, anastomotic component 3 is installed in the front end of moving body 2, moving body 2 is installed on the supporting plate 5 movably, nail supporting base 4 is installed in the front end of supporting plate 5, by rivet safety block 7 is arranged on the side plate of moving body 2, torsion spring (8) is installed on the rivet, one end of torsion spring 8 is against on the moving body 2, the other end is against on the safety block 7, and the free end of safety block 7 is equipped with pin 6, and the boss 5-1 corresponding with this pin 6 is installed on supporting plate 5.
Shown in Fig. 4,5, anastomotic component 3 is made up of anastomosis staple 3-3, pushing slice of nail 3-2 and nail bin 3-1.Anastomosis staple 3-3 and pushing slice of nail 3-2 are installed on the nail bin 3-3, and pushing slice of nail 3-2 is positioned at the rear of anastomosis staple 3-3.
Operation principle of the present utility model is as follows:
Shown in Fig. 1 ~ 2, turn adjusting nut 1, making moving body 2 drive anastomotic component 3 moves to nail supporting base 4, in the process that moves, boss 5-1 on the supporting plate 5 can slowly depress the pin 6 under the safety block 7, and safety block 7 and then pin 6 is also being opened at leisure, when reaching can pull the trigger the zone time, safety block 7 is opened fully, at this moment just can pull the trigger.
