Abstract
The utility model discloses a kind of anti-error percussion safety devices of Endo-GIA, including limiting device and gear device, the limiting device includes the driving lever being located on Endo-GIA shell and is located at the intracorporal limited post of cutter stapler shell, and the driving lever is connect with the limited post；The gear device includes gear block, and the gear block is equipped with neutral gear and limiting block；When driving lever drags on limiting block, limited post resists cam boss, and cam is rotated by limitation.The utility model is simple and practical in structure, and by the way that gear device is arranged, limitation cam rotation, to limit, pushing block is mobile, reduces the risk of mistakenly hit hair in instrument automatic firing in transportational process and use process.
Description
Technical field
The utility model relates to a kind of anti-error percussion of Endo-GIA technical field more particularly to Endo-GIA insurances
Device.
Background technique
Currently, linear cutting anastomat is primarily adapted for use in outside gastrointestinal tract surgery, gynaecology, thoracic surgery (lobectomy of lungs) and children
The detachment of histoorgan cuts off and coincide in section's (children's stomach, enteron aisle) operation.Operation consent first opens flexible handle, by nail anvil group
Pairing after part and nail bin groupware are placed on the tissue two sides wait perform the operation, then flexible handle is closed, by nail-anvil assembly and nail bin group
Then part locking pushes forward percussion button, percussion button connects pushing block, and pushing block connects nail pushing plate and cutter, and nail pushing plate will
Suturing nail release carries out tissue suture, while the tissue after suture is cut off in cutter Forward, completes operation.It is cut in linear type
Cam can limit the moving distance of pushing block when instrument does not fire in stapler, and in the initial offer resistance of percussion,
Prevent mistakenly hit from sending out.Current problem is: having hinder because the transports factor such as vibrate, falling and instrument cam is caused to break through in transit
Power pushes forward nail pushing plate, leads to the risk of front-seat anastomosis staple advanced primer ignition；Linear cutting anastomat band is free nail bin to hit
Hair insurance, cam are likely to result in cutter and empty nail bin are insured opening, after empty nail bin insurance is opened, then will promote when moving
Block is pulled back, is fired, then can not be fired, and brings risk to operation；In addition, doctor is in use, manual override cam resistance
Also the risk of wrong percussion.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of anti-error percussion insurance of Endo-GIA
The risk of instrument automatic firing in transportational process is effectively reduced in device.
The utility model solves technical solution used by prior art problem: a kind of anti-error percussion guarantor of Endo-GIA
Dangerous device, including limiting device and gear device, the limiting device include the driving lever being located on Endo-GIA shell and set
In the intracorporal limited post of cutter stapler shell, the driving lever is connect with the limited post；The gear device includes gear block,
The gear block is equipped with neutral gear and limiting block；When driving lever drags on limiting block, limited post resists cam boss, and cam is turned by limitation
It is dynamic.
Further, the limited post is with spring, and the spring is connect with driving lever, and spring is initially in compressive state,
When driving lever drags on neutral gear, spring moves up driving lever, and limited post is separated with cam boss, and instrument can fire.
The utility model has the beneficial effects that:
The utility model is simple and practical in structure, by the way that gear device, limitation cam rotation, to limit pushing block shifting is arranged
It is dynamic, reduce the risk of instrument automatic firing in transportational process.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Embodiment one
A kind of anti-error percussion safety device of Endo-GIA as shown in Figures 2 to 6, including limiting device and gear dress
It sets, the limiting device includes the driving lever 2 being located on Endo-GIA shell 1 and the limit that is located in cutter stapler shell 1
Position column 3, the driving lever 2 are connect with the limited post 3；The gear device includes gear block 4, and the gear block 4 is equipped with neutral gear 5
With limiting block 6；When driving lever 2 drags on limiting block 6, limited post 3 resists cam boss 7, and cam 10 is rotated by limitation, pushing block 9
Moving distance limited.
As shown in Fig. 2, the outside of the limited post 3 is with spring 8, the spring 8 is connect with driving lever 2, and spring 8 is initial
In compressive state, when driving lever 2 drags on neutral gear 5, spring 8 moves up driving lever 2, and limited post 3 divides with cam boss 7
It opens, instrument can fire.
Specific case used herein is expounded the principles of the present invention and embodiment, above embodiments
Explanation be merely used to help understand the method and its core concept of the utility model.It should be pointed out that for the art
For those of ordinary skill, under the premise of not departing from the utility model, can also to the utility model carry out it is several improvement and
Modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
