Description
Technical field
The present invention relates to a kind of assembling fixture of stapler, belong to the Machining Technology field.
Background technology
Operation is the medicine equipment that often uses when physiological tissues such as esophagus, enteron aisle are undergone surgery seaming and cutting with the tubular type stapler, and the quality of its performance directly influences the operation process, plays important effect for surgical effect.In the prior art; Like the tubular type binding appearance that U.S. Pat 5205459 discloses, generally form by having the body 1 of pulling the trigger handle 2 and having the crimp head of sewing up device, as shown in Figure 2; Be provided with a grip return spring 3 between said body 1 and the percussion handle 2; Said handle return spring 3 is sleeved on the percussion handle 2, and one of which end 4 is against on the percussion handle 2, and the other end 5 is against on the body 1.But, there is not good fixture can it be loaded onto at present because the elastic force of handle return spring 3 is very big.At present unique way is exactly artificial assembling, but the unfavorable factor of bringing is to waste time and energy, and assembles and be not easy at that time the outer surface of body 1 is scratched, and influences attractive in appearance.
The present invention quotes the content that this patent is put down in writing as prior art.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, the handle return spring assembling fixture of the good stapler of a kind of effect is provided.
The object of the invention is realized through following technical scheme:
A kind of assembling tool for anastomat is used for the installation of the handle return spring of stapler, and said stapler comprises body and the pivotal connection percussion handle on it; Be provided with a grip return spring between said body and the percussion handle; Said handle return spring is placed on the pivot pin, and an end of said handle return spring is connected on the said body, and the other end is connected on the said percussion handle; Said fixture comprises the compressing member of a cover half and one group of activity; The body of said stapler can be pressed on the said cover half by said compressing member with the percussion handle, and said cover half head lamp brush guard pivot is provided with a column, and said column head lamp brush guard pivot is provided with a lever; One end of said lever is the effect end, and the other end is the support end of support handle return spring.
Further, said compressing member is connected with a cylinder and drives reciprocating motion by said cylinder.
Further, said cover half is provided with recess, and the inner surface of said recess is identical with the outline of partly pulling the trigger handle with the part body of said stapler.
Further, said stapler comprises tubular type bowel anastomosis device and hemorrhoid anastomat.
Beneficial effect of the present invention is mainly reflected in: utilize lever principle can be very like a cork the handle return spring to be packed in the body, improved efficient, assembling speed also greatly improves.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:

The specific embodiment
The present invention has disclosed a kind of fixture, is used for the installation of the handle return spring of stapler.
In conjunction with illustrated in figures 1 and 2; Said stapler comprises body 1 and the pivotal connection percussion handle 2 on it; Be provided with a grip return spring 3 between said body 1 and the percussion handle 2; Said handle return spring 3 is placed on the pivot pin, and an end 4 of said handle return spring 3 need be connected on the said percussion handle 2, and the other end 5 need be connected on the said body 1.
Said stapler is in the process of handle return spring 3 assemblings; Earlier handle return spring 3 is packed in the cavity of said percussion handle 2; Then pack pivot pin on the said percussion handle 2 into; At this moment an end 4 of handle return spring 3 has been connected on the said percussion handle 2, and the other end 5 also is exposed to outside the said body 1.The purpose of fixture of the present invention is exactly in order more easily the other end 5 of said handle return spring 3 to be encased in the said body 1.
Said fixture comprises the compressing member 8 of a cover half 6 and one group of activity, and the body 1 of said stapler can be pressed on the said cover half 6 by said compressing member 8 with percussion handle 2.In this preferred embodiment; Be provided with 3 mobilizable compressing members 8 on the said cover half 6 altogether; Be pressed in respectively on the body 1 and percussion handle 2 of said stapler; Said compressing member 8 all is connected with a cylinder (not shown) and drives reciprocating motion by said cylinder, so just can grasp said stapler well.
This preferred embodiment also is provided with recess 7 in order to grasp said stapler better on said cover half 6, the inner surface of said recess 7 is identical with the outline of partly pulling the trigger handle 2 with the part body 1 of said stapler.Like this, can stapler be placed said recess 7, and then compress said compressing member 8 again, just can grasp said stapler better.
Said cover half 6 head lamp brush guard pivots are provided with a column 9, and said column 9 head lamp brush guard pivots are provided with a lever 10, and an end of said lever is effect end 11, and the other end is the support end 12 of support handle return spring 3.In the operation, said support end 12 is butted on earlier on the other end 5 of handle return spring 3, the operator pushes said effect end 11 with hand or machine because lever principle, just can be very like a cork with the other end 5 perks of said handle return spring 3; Then hold said support end 12 application of forces and slowly rotate said column 9, just can the other end 5 of said handle return spring 3 be snapped onto on the body 1 of said stapler.
In order to make lever 10 well hold the other end 5 of said handle return spring 3, its support end 12 is processed the inclined-plane with certain angle, makes column 9 in the process of rotation, and handle return spring 3 can be not excessive and drop out from the support end 12 of lever 10 owing to elastic force.
The present invention adopts lever principle and mechanized operation, can be very like a cork the handle return spring be packed in the body, has improved efficient, and assembling speed also greatly improves.
The present invention still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming all drop within the scope of requirement protection of the present invention.
