Abstract
The utility model discloses a kind of chocking construction of anastomat push pedal, comprise and push pedal is advanced spacing scotch, described scotch one end is that stiff end is provided with round platform, round platform is fixed on fixing head, the other end is stop end, and stop end pushed down by pressing plate, and pressing plate at least has the degree of freedom that moves both vertically, scotch, along round platform center small angle rotation, is provided with the shell fragment to scotch force between round platform and stop end.This utility model structure is relatively simple, easy to assembly, stopping effect is reliable.
Description
Technical field
This utility model relates to surgery medical apparatus and instruments, specifically be a kind of chocking construction of anastomat push pedal.
Background technology
In cutting anastomosis operation, adopt Endo-GIA to reduce operating time, improve surgical quality.When realizing cutting and stitching action, often being travelled forward by the push pedal be connected with firing handle and promoting pushing slice of nail and/or cutter carry out sewing up and/or cutting.In order to ensure the safety that anastomat uses, needing push pedal can not advance and the propelling that can move ahead when pulling the trigger at non-cock, thus completing stitching cutting action.The chocking construction of existing anastomat push pedal is complicated, assembling trouble.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of structure is relatively simple, easy to assembly, the chocking construction of the reliable anastomat push pedal of stopping effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of chocking construction of anastomat push pedal, comprise and push pedal is advanced spacing scotch, described scotch one end is that stiff end is provided with round platform, and round platform is fixed on fixing head, and the other end is stop end, stop end pushed down by pressing plate, pressing plate at least has the degree of freedom that moves both vertically, and scotch, along round platform center small angle rotation, is provided with the shell fragment to scotch force between round platform and stop end.
Shell fragment can be stage clip, torsion spring, leaf spring etc., and shell fragment can be fixed on fixing head or scotch.
Described round platform is more than half round.
Described pressing plate can have horizontal movement degree of freedom.
The beneficial effects of the utility model are, scotch vibrational power flow is reasonable, and scotch stiff end adopts frustum cone structure assembling simple, reliable.Original state stop end is positioned at stop position and carries out spacing to push pedal, and push pedal can not be pushed ahead; When pressing plate presses down scotch, the stop end of scotch is stepped down, and pushing block can be pushed ahead; Press down shell fragment accumulation potential energy in process at pressing plate, after scotch loses the pressure of pressing plate, shell fragment elastic force makes scotch reset.

Detailed description of the invention
As depicted in figs. 1 and 2, the chocking construction of this utility model anastomat push pedal, comprise the scotch 2 of advancing spacing to push pedal 4, described scotch 2 one end is that stiff end is provided with round platform 22, round platform 22 is fixed on fixing head 3, and the other end is stop end 21, and stop end 21 pushed down by pressing plate 1, pressing plate 1 at least has the degree of freedom that moves both vertically, and namely can move up and down in the drawings.Scotch 2, along round platform 22 center small angle rotation, is provided with the shell fragment 5 exerted a force to scotch 2 between round platform 22 and stop end 21.Shell fragment 5 pairs of scotch 2 always have elastic force effect, impel scotch 2 to be in balance resting state in stop position.Fixing head 3 is fixed in frame by pin 6, is fixed part.
As a kind of optimal way round platform 22 for exceeding the round platform of semicircle, be arranged in the arcuate groove on fixing head, thus make scotch can only with the center small angle rotation of round platform.
As shown in Figure 1, during original state, scotch 2 is not depressed by pressing plate 1, and the stop end 21 of scotch is in stop position, has barrier effect to advancing of push pedal 4, and push pedal 4 can not be pushed ahead (namely in figure can not to left movement).
As shown in Figure 2, after scotch 2 is moved downward pressure by pressing plate 1, scotch 2 is compression shell fragment 5 further, makes shell fragment 5 accumulate more potential energy.When the stop end 21 of scotch 2 departs from stop position, cannot stop push pedal 4, push pedal 4 can (left) advance forward.
When push pedal 4 completes propelling action return, if when push pedal 4 is pushed ahead, pressing plate 1 does not advance together with push pedal 4, and only push pedal 4 advances, and now scotch 2 still pushed down by pressing plate 1, to complete after propelling action push pedal 4 can easily rollback to home position.If pressing plate 1 is also pushed ahead when push pedal 4 is pushed ahead, fillet structure can be set in push pedal rear end, during rollback, press down scotch 2 with fillet structure, make push pedal 4 can rollback to original position.
When pressing plate 1 move upward return or by push pedal be pushed to left side time, scotch 2 loses the pressure of pressing plate 1, under the elastic force of shell fragment, return to initial position.
The chocking construction of above-mentioned anastomat push pedal goes for multiple anastomat, and if Fig. 3 and Fig. 4 is the embody rule of this utility model chocking construction on stapler, Fig. 5 and Fig. 6 is the application on Linear stapler.
