Abstract

The invention discloses a tubular anastomat with a non-return function. The tubular anastomat comprises a fixed handle and a mobile handle, wherein a bent push rod which is pushed and started by the mobile handle is arranged in the fixed handle; racks are arranged at the back of the tail end of the bent push rod; a stop block is arranged on one side, corresponding rack surfaces, of the racks; the end part of the stop block is coordinated with the racks in a clamping manner along with the moving of the bent push rod, so that, after being triggered, the mobile handle can be stopped at any position. According to the tubular anastomat, a row of racks are additionally arranged at the tail end of the bent push rod, by using the meshing blocking of the stop block and the racks during a moving process, the mobile handle can be stopped at any time when the mobile handle is triggered to one position, so that mesh failure caused by phenomenon of slipping and the like is prevented, the mobile handle is enabled to be reset after reaching to the end, and the completeness of each triggering is ensured.

Description

There is the tubular anastomat of inverse-stopping functions
Technical field
The present invention relates to technical field of medical instruments, especially a kind of tubular anastomat with inverse-stopping functions.
Background technology
Flexible handle in tubular anastomat is when pulling the trigger, curved push rod is driven to move forward and promote anastomosis cut component action, existing tubular anastomat in use, be difficult to after flexible handle percussion stop completely in certain position middle, phenomenons such as easy generation skidding and cause coincideing unsuccessfully, meanwhile, for ensureing the integrity of each percussion, require that flexible handle percussion can reset after putting in place, and existing anastomat structure is difficult to control this point.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of in percussion process, can guarantee that flexible handle stops completely at an arbitrary position and pulls the trigger the tubular anastomat with inverse-stopping functions of integrity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tubular anastomat with inverse-stopping functions, comprise fixed handle, flexible handle, the curved push rod being promoted percussion by flexible handle is provided with in fixed handle, the described curved push rod tail end back side is provided with tooth bar, corresponding tooth surface of rack side is provided with limited block, described limited block end move with curved push rod and with tooth bar snap-fit engagement realize flexible handle pull the trigger after stopping at an arbitrary position.
Further, described limited block is connected with fixed handle inwall by torsion spring, and like this in tooth bar moving process, limited block is dodged and engagement process by torsion spring effect realization and tooth bar.
Being provided with in described fixed handle after unclamping flexible handle makes flexible handle automatically reset to the back-moving spring of original position.
The invention has the beneficial effects as follows: the present invention by increasing by a tooth-arranging strip on curved push rod tail end; limited block is utilized to snap in engaging of optional position in tooth bar moving process; flexible handle can be stopped to during a certain position at any time in percussion; prevent the identical failure caused due to phenomenons such as skiddings; guarantee just can reset after flexible handle on earth, ensure the integrity of each percussion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.

Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, a kind of tubular anastomat with inverse-stopping functions shown in Fig. 2, comprise fixed handle 1, flexible handle 2, anastomosis cut component and nail supporting base, the curved push rod 3 being promoted percussion by flexible handle 2 is provided with in fixed handle 1, curved push rod 3 is connected with the pushing slice of nail in anastomosis cut component, the described curved push rod 3 tail end back side is provided with tooth bar 4, corresponding tooth bar 4 flank of tooth side is provided with limited block 5, described limited block 5 is connected with fixed handle 1 inwall by torsion spring 6, in percussion process, described limited block 5 end move with curved push rod 3 and with tooth bar 4 snap-fit engagement, when unclamping flexible handle 2 at an arbitrary position, limited block 5 snaps in tooth bar 4 profile of tooth, flexible handle 2 keeps motionless, achieve flexible handle 2 stopping completely at an arbitrary position.
Be provided with a moveable screw mandrel 8 in fixed handle 1, screw mandrel 8 front end connecting bending push rod 3, screw mandrel 8 and the nut 9 be located in fixed handle 1 are rotationally connected, and screw mandrel 8 rear end is connected with the adjusting knob turning screw mandrel 8.
Being provided with in fixed handle after unclamping flexible handle makes flexible handle automatically reset to the back-moving spring of original position, each percussion is complete unclamp flexible handle 2 after, flexible handle 2 automatically resets to original position under action of reset spring, so that percussion next time.
The present invention by increasing by a tooth-arranging strip 4 on curved push rod 3 tail end; limited block 5 is utilized to snap in engaging of optional position in tooth bar 4 moving process; flexible handle 2 can be stopped to during a certain position at any time in percussion; prevent the identical failure caused due to phenomenons such as skiddings; guarantee just can reset after flexible handle 2 on earth, ensure the integrity of each percussion.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
