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, particularly relate to a kind of chocking construction of anastomat push pedal.
Background technology
In cutting anastomosis operation, operating time can be reduced using Endo-GIA, improve surgical quality.Realizing cutting
During slot conjunction action, often travelled forward by the push pedal being connected with firing handle and promote pushing slice of nail and/or cutter to be sutured
And/or cutting.In order to ensure anastomat use safety, need push pedal unfired state can not advance and percussion when can
With the propulsion that moves ahead, thus completing to suture cutting action.The chocking construction of existing anastomat push pedal is complicated, assembling trouble.
Content of the invention
The technical problem to be solved in the present invention is to provide that a kind of structure is relatively easy, easy to assembly, stopping effect is reliable
The chocking construction of anastomat push pedal.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of chocking construction of anastomat push pedal,
Including spacing scotch that push pedal is advanced, described scotch one end is provided with round platform for fixing end, and round platform is fixed in fixed plate,
The other end is stop end, and pressing plate pushes down stop end, and pressing plate at least has vertical movement degree of freedom, and scotch is along round platform center little Jiao
Degree 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 fixed plate 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, rationally, scotch fixing end adopts frustum cone structure assembling letter to scotch structure setting
Single, reliable.Original state stop end carries out spacing positioned at stop position to push pedal, and push pedal can not be pushed ahead；When pressing plate only pushes
Motion block, the stop end of scotch is stepped down, and pushing block can be pushed ahead；Shell fragment accumulation potential energy during pressing plate pushes, scotch loses
After removing the pressure of pressing plate, shell fragment elastic force makes stop block reset.

Specific embodiment
As depicted in figs. 1 and 2, the chocking construction of anastomat push pedal of the present invention, including spacing scotch that push pedal 4 is advanced
2, described scotch 2 one end is provided with round platform 22 for fixing end, and round platform 22 is fixed in fixed plate 3, and the other end is stop end 21, pressure
Stop end 21 pushed down by plate 1, and pressing plate 1 at least has vertical movement degree of freedom, can move up and down in figure.Scotch 2 is along circle
Platform 22 center small angle rotation, is provided with the shell fragment 5 to scotch 2 force between round platform 22 and stop end 21.Shell fragment 5 is to scotch
2 always elastic effects, promote scotch 2 to be in balance resting state in stop position.Fixed plate 3 is fixed to frame by pin 6
On, it is fixed part.
It is the round platform exceeding semicircle as a kind of optimal way round platform 22, be arranged in the arcuate groove in fixed plate, thus
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, the stop end 21 of scotch is in stop position,
Traveling to push pedal 4 has barrier effect, and push pedal 4 can not be pushed ahead（I.e. in figure can not be to left movement）.
As shown in Fig. 2 after scotch 2 is moved downward pressure by pressing plate 1, scotch 2 compresses shell fragment 5 further, makes bullet
Piece 5 accumulates more potential energy.When the stop end 21 of scotch 2 departs from stop position it is impossible to stop push pedal 4, push pedal 4 can be forward
（To the left）Propulsion.
When push pedal 4 completes propulsion action return, if push pedal 4 is pushed ahead, pressing plate 1 is not advanced together with push pedal 4, only
Push pedal 4 advances, and now scotch 2 still pushed down by pressing plate 1, complete after propulsion action push pedal 4 can easily rollback to home position.As
When fruit push pedal 4 is pushed ahead, pressing plate 1 is also pushed ahead, and can arrange fillet structure, fillet structure during rollback in push pedal rear end
Push scotch 2 so that push pedal 4 can rollback in situ.
When pressing plate 1 upwards motion return or by push pedal be pushed to left side when, scotch 2 loses the pressure of pressing plate 1, in shell fragment
Elastic force under recover to initial position.
The chocking construction of above-mentioned anastomat push pedal goes for multiple anastomats, and such as Fig. 3 and Fig. 4 is stop of the present invention
Concrete application on stapler for the structure, Fig. 5 and Fig. 6 is the application on Linear stapler.
