The utility model discloses promote linear -cutting anastomat that piece was provided with stop device, simple structure, guide way vertically are provided with the stop device that the restriction promoted the piece upward movement, and the side increases a slice limiting plate on following closely storehouse splint guide way promptly for promote the action that the piece can be steady in excitation process, reduce the excitation force, guarantee operation stability.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, relates to the linear cutting anastomat that a kind of pushing block is provided with stopping means.
Background technology
At present, linear cutting anastomat is mainly applicable to gastrointestinal tract surgery, gynecological, thoracic surgery (lobectomy of lungs) and pediatric surgery (children's's stomach, intestinal) operation in histoorgan from disconnected excision and coincide, linear cutting anastomat one form by nail supporting base with the nail bin groupware of flexible handle, flexible handle is first opened by operation consent, nail supporting base and nail bin groupware are put in tissue two rear flank to be performed the operation involutory, again flexible handle is closed, by nail supporting base and nail bin groupware locking, then driven forward percussion button, percussion button connects pushing block, pushing block connects nail pushing plate and cutter, suturing nail is released and is carried out tissue apposition by nail pushing plate, tissue after stitching cuts off by cutter reach simultaneously, complete operation.
But, the pushing block of existing linear cutting anastomat in the process excited due to stressed larger, can be crooked inside apparatus, pushing slice of nail in whole percussion process is advanced and is not in straight line stress, and then overall percussion force is excessive, so not only affect surgical feel, more likely make firing button rupture, and then cause device failure, operative failure.
Utility model content
For above-mentioned deficiency of the prior art, this utility model provides a kind of structure simple, and easy to operate, the pushing block preventing firing button from rupturing is provided with the linear cutting anastomat of stopping means.
Technical solution adopted in the utility model is:
Pushing block is provided with a linear cutting anastomat for stopping means, comprising: nail bin groupware clamping plate, and described nail bin groupware clamping plate are provided with gathering sill; Be provided with pushing block in described gathering sill, described pushing block front end is connected with cutter with nail pushing plate, and described nail bin groupware clamping plate sidewall is provided with rectangular indexing holes; Described rectangular indexing holes is arranged along nail bin groupware clamping plate length direction; Guide plate is provided with in described rectangular indexing holes; Described guide plate is provided with positioning convex; Shape and the rectangular indexing holes shape of described positioning convex are suitable; Described positioning convex and rectangular indexing holes are interference fit.
Described guide plate lower surface and pushing block upper surface distance are 0.5-1 millimeter.
Described guide plate width is 1/1 to two/3rd of nail bin groupware clamping plate gathering sill width.
Described rectangular indexing holes quantity is 3-5.
The beneficial effect of this utility model hinge structure:
This utility model pushing block is provided with the linear cutting anastomat of stopping means, structure is simple, gathering sill is vertically arranged with the stopping means that restriction pushing block moves upward, namely a slice limiting plate is increased at nail bin clamping plate gathering sill upper side, make pushing block can action stably in excitation process, reduce evocatory, ensure operative stabilization.
