Abstract
The invention discloses a stop structure for a push plate of a stapling device. The stop structure comprises a stopping block for limiting the push plate, wherein one end of the stopping block is a fixed end provided with a circular table fixed on a fixed plate, and the other end of the stopping block is a stopping end pressed by a pressing plate; the pressing plate is at least provided with the freedom of vertical motion, the stopping block rotates along the center of the circular table at a small angle, and an elastic piece used for applying force to the stopping block is arranged between the circular table and the stopping end. The stop structure provided by the invention is relatively simple in structure, convenient to assemble, and reliable in stopping effect.
Description
Technical field
The present invention 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 can reduce operating time, improve operation quality.Realizing cutting and stitching when action, often by the push pedal being connected with firing handle, travelling forward and promote pushing slice of nail and/or cutter are sewed up and/or cut.For the safety that guarantees that anastomat uses, need push pedal can not advance and the propelling that can move ahead when pulling the trigger at non-percussion state, thereby complete stitching cutting action.The chocking construction of existing anastomat push pedal is complicated, assembling trouble.
Summary of the invention
The technical problem to be solved in the present invention 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 used in the present invention is: a kind of chocking construction of anastomat push pedal, comprise the push pedal spacing scotch of advancing, 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, pressing plate is pushed down stop end, pressing plate at least has the degree of freedom of moving both vertically, and scotch, along round platform center small angle rotation, is provided with the shell fragment to the scotch application of 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 invention has the beneficial effects as follows, scotch structure arranges rationally, and scotch stiff end adopts frustum cone structure assembling simple, reliable.Original state stop end is positioned at stop position and push pedal is carried out spacing, 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; At pressing plate, press down shell fragment in process and accumulate potential energy, after scotch loses the pressure of pressing plate, shell fragment elastic force resets scotch.

The specific embodiment
As depicted in figs. 1 and 2, the chocking construction of anastomat push pedal of the present invention, comprise the push pedal 4 spacing scotch 2 of advancing, described scotch 2 one end are 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 pressing plate 1 is pushed down stop end 21, pressing plate 1 at least has the degree of freedom of moving both vertically, and can move up and down in the drawings.Scotch 2 is along round platform 22 center small angle rotations, and 21 of round platform 22 and stop end are provided with the shell fragment 5 to scotch 2 application of forces.5 pairs of scotch 2 of shell fragment always have elastic force effect, impel scotch 2 in stop position in balance resting state.Fixing head 3 is fixed in frame by pin 6, is fixed part.
As a kind of optimal way round platform 22, for surpassing the round platform of semicircle, be arranged in the arcuate groove on fixing head, thereby make the scotch can only be 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, in stop position, has barrier effect to advancing of push pedal 4, and push pedal 4 can not be pushed ahead (in figure can not to left movement).
As shown in Figure 2, after scotch 2 is moved downward by pressing plate 1 and depresses, scotch 2 is compression shell fragment 5 further, makes shell fragment 5 accumulate more potential energy.Stop end 21 disengaging stop positions when scotch 2, cannot stop push pedal 4, and push pedal 4 forward (left) advances.
Push pedal 4 completes while advancing 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 pressing plate 1 is still pushed down scotch 2, complete advance after action push pedal 4 easily rollback to home position.If pressing plate 1 is also pushed ahead when push pedal 4 is pushed ahead, can fillet structure be set in push pedal rear end, during rollback, with fillet structure, press down scotch 2, make push pedal 4 can rollback to original position.
When move upward return or be pushed to when left side by push pedal of pressing plate 1, scotch 2 loses the pressure of pressing plate 1, under the elastic force of shell fragment, returns to initial position.
The chocking construction of above-mentioned anastomat push pedal goes for multiple anastomat, and if Fig. 3 and Fig. 4 are the concrete application of chocking construction of the present invention on stapler, Fig. 5 and Fig. 6 are the application on Linear stapler.
