Description
Technical field
The present invention relates to stapler manufacturing technology field, especially a kind of push broach rod bending suitable for stapler, which deforms, to be mended
Repay mechanism.
Background technique
In laparoscopically surgical operation and thoracoscopic surgical, hysteroscope Endo-GIA is normally used for eating in alimentary canal
Pipe, Stomach duodenum, small intestine, colon, rectum, appendix, gallbladder, pancreas and spleen etc. cut anastomosis operation, are also used for lung in respiratory tract
With the cutting anastomosis operation such as tracheae, also it is used for bladder and uterus etc. in urogenital system and cuts anastomosis operation, answered by it
With operation wound mouth can be greatly reduced, shortens operating time and improve surgical quality.
In actual use, in order to ensure jaw relative to the positional accuracy of pathological tissues and improves operation
Convenience, doctor need to carry out adaptivity yaw to it according to the actual situation.In the prior art, hysteroscope Endo-GIA tool
Swing be all to be realized by the elastic deformation of push broach bar assembly, and most of push broach bar assembly is all made of more metallic sheets
(general 4-5 piece) is combined.One end of push broach bar assembly is connect with basic blocks, be reserved between the other end and connector compared with
Big free gap (as shown in fig. 1).But during push broach bar assembly bends elastic deformation, it is located at outside
Two metal sheets amount of elastic deformation it is necessarily inconsistent, it is different so as to cause the amount of moving forward and backward of the two, to easily lead to it
The sheet metal of middle side and the free gap first amount of the being displaced by counteracting of basic blocks, so that mutually being pushed up between push broach bar assembly and basic blocks
Extremely, on the one hand, the swingable angle of yaw can be made to be restricted, so that expected swaying angle be not achieved；On the other hand, also
Meeting is so that " bulge " metaboly occurs for sheet deformation part, so as to cause holding for the subsequent percussion process of stapler is unfavorable for
Row, and then cause percussion force excessive, it is unfavorable for the operation of medical worker.Thus, it would be highly desirable to technical staff solves the above problems.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of designs of structure simply, goes slick, and effectively prevent jaw
Catching phenomenon occurs in swing process, and reduces the deformation-compensated machine of push broach rod bending suitable for stapler of required percussion force
Structure.
In order to solve the above-mentioned technical problem, the present invention relates to a kind of push broach rod bending suitable for stapler is deformation-compensated
Mechanism, including push broach bar assembly, sebific duct part, connector, basic blocks, wherein connector is connected to the left part of push broach bar assembly.
Basic blocks are sheathed on freely slidablely in sebific duct part, to push push broach bar assembly to be moved along the axial direction of sebific duct part.Separately
It outside, further include swinging block suitable for the deformation-compensated mechanism of push broach rod bending of stapler, by mounting portion and compensation function portion structure
At.Mounting portion is rotatably inserted in basic blocks.Slot is offered in push broach bar assembly, for accommodating compensation function
Portion.
As the further improvement of presently disclosed technical solution, in above-mentioned compensation function portion, just correspond to slot
Side wall be provided with arc compensation curved surface.
As the further improvement of presently disclosed technical solution, in left-right direction, above-mentioned swinging block is relative to slotting
Slot is provided with gap between two sidewalls.
As the further improvement of presently disclosed technical solution, the width value of above-mentioned push broach bar assembly is set as a,
The depth value of slot is set as b, then 2/5a≤b≤3/5a.
As the further improvement of presently disclosed technical solution, above-mentioned push broach bar assembly is folded by multiple elastic metal sheets
Add.
As the further improvement of presently disclosed technical solution, above-mentioned mounting portion is in ladder shaft-like, correspondingly, in base
Mounting hole compatible with mounting portion is offered on plinth block.
As the further improvement of presently disclosed technical solution, above-mentioned sebific duct part is by upper pipe fitting and lower pipe fitting split
It forms, and is provided with the compatible guide groove of push broach bar assembly in its cavity.
Compared to the design structure of traditional stapler, in technical solution disclosed in this invention, additionally increase into swing
Block.In this way, in the actual operation process, when yaw movement occurs for jaw, connector correspondingly rotates movement, same with this
When, interior elasticity of flexure deformation occurs for push broach bar assembly, and then swinging block is driven to carry out adaptive rotary motion around center axis thereof,
To avoid push broach bar assembly that dieback phenomenon occurs relative to basic blocks, it is ensured that jaw yaw movement process is gone on smoothly；Separately
Outside, percussion force needed for also reducing instrument to a certain extent, to improve the operation ease of medical worker.
