The instrument has the advantages that: the instrument is easy to use, can lighten the load of a doctor and can automatically finish suturing and cutting after the nail cabin and the nail anvil are closed.
Description
Technical field
The present invention relates to a kind of novel surgical incision stapler, belong to medical instruments field.
Background technology
Surgical incision stapler is widely used in being used in the surgical operation wound suture, interior tissue is sewed up and cutting.Typical surgical incision stapler has: the final suturing part that U.S. Pat 5275322 discloses is circular tubular type stapler, and perhaps the final suturing part of U.S. Pat 5065929 announcements is collinear linear type stapler.Above-mentioned apparatus generally has to be sewed up and two functions of cutting, when carrying out wound suture, excess tissue is excised.Existing linear type stapler also need manually promote push button after closed handle is with nail bin and nail anvil closure, and the pushing slice of nail and the cutting knife that are positioned at nail bin are advanced, and then accomplishes and sew up and cutting.But in some operations, thicker owing to organizing, manually promote push button, waste time and energy.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, provide a kind of simple in structure, sew up the surgical incision stapler of cutting automatically.
The object of the invention is realized through following technical scheme:
A kind of stapler with accumulating mechanism comprises the nail bin and the nail anvil that are oppositely arranged, is disposed with suturing nail in the said nail bin; Said stapler also comprises the pushing slice of nail and the cutting knife that can move relative to said nail bin simultaneously; Said pushing slice of nail is pushed suturing nail to nail anvil, and said cutting knife will cut off at the tissue between nail bin and the nail anvil, and said stapler also comprises an accumulating mechanism; Said accumulating mechanism is fixedly connected with cutting knife with pushing slice of nail; Said accumulating mechanism has initial accumulation of energy and discharges two states, and when accumulating mechanism switched between two states, said pushing slice of nail and cutting knife moved with respect to nail bin.
Further, said accumulating mechanism is an elastic component.
Again further, said elastic component is a wind spring.Said stapler also comprises a knob that tightens up that is used to tighten up wind spring; Comprise the axle on the rotating handles that is arranged on rotationally on the stapler shell and the rotation axis that is vertically set on said rotating handles, said end, center clamping with wind spring.
Perhaps, said accumulating mechanism is the bent Metallic rod with memory function.
Again further, the end of said pushing slice of nail and cutting knife is fixed on the ejector pin bar simultaneously, said accumulating mechanism and ejector pin bar Joint.
Further, said ejector pin bar is provided with a recess, and the button that pivot is located on the stapler shell comprises a projection, and said projection extend in the recess.
Beneficial effect of the present invention is mainly reflected in: instrumentation is simple, can alleviate doctor's burden, after with nail bin and nail anvil closure, can accomplish automatically and sew up and cutting.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: the structural representation of stapler of the present invention.
Fig. 2: the preferred embodiment of accumulating mechanism of the present invention is at the structural representation of starting stage.
The vertical view of Fig. 3: Fig. 2.
Wherein:
1 nail bin, 2 nail anvils, 3 closed handle
4 buttons, 5 wind springs, 6 ejector pin bars
7 pushing slice of nail, 9 recesses, 10 projections
12 13 rotating handleses of 11 pivots
The specific embodiment
The present invention has disclosed a kind of surgical incision stapler, is example with the side side type surgical incision stapler shown in Fig. 1, and it comprises upper and lower closed clamp and a closed handle 3.Be oppositely arranged one group of nail bin 1 and nail anvil 2 on the described upper and lower closed clamp.Described closed handle 3 can be moved between open position and make position; When closed handle is shown in an open position; Upper and lower closed clamp is in the position of opening relatively, and when closed handle was in the close position, upper and lower closed clamp was in sufficiently closed position.
As shown in Figure 2; Said stapler also comprises the pushing slice of nail 7 and cutting knife (not shown) that can move relative to said nail bin 1 simultaneously; The end of said pushing slice of nail 7 and cutting knife is fixed on the ejector pin bar 6 simultaneously; Said pushing slice of nail 7 is pushed the suturing nail that arrangement is arranged in the nail bin to nail anvil 2, and said cutting knife will cut off at the tissue between nail bin 1 and the nail anvil 2.
Stapler of the present invention also comprises an accumulating mechanism, and in preferred embodiment shown in Figure 2, accumulating mechanism is an elastic component, is a wind spring 5 specifically.One end of described wind spring 5 and ejector pin bar 6 Joints; It has initial accumulation of energy and discharges two states; When wind spring 5 was in initial energy accumulating state, ejector pin bar 6, pushing slice of nail 7 and cutting knife all were positioned at the first beginning and end firing position of stapler, when release wind spring 5 makes it slowly return to release conditions; One end of wind spring 5 will promote ejector pin bar 6, pushing slice of nail 7 and cutting knife and slowly move to the front end of stapler, realizes automatic sewing and cutting.
Further, said ejector pin bar 6 is provided with a recess 9, and the button of being located on the stapler shell through pivot 11 4 comprises a projection 10, and said projection 10 can extend in the recess 9.When wind spring 5 was in initial energy accumulating state, projection 10 extend in the recess 9, guaranteed that ejector pin bar 6 can not promoted by wind spring 5; When pressing the button 4, button 4 rotates around pivot 11, and projection 10 withdraws from from recess 9, and at this moment wind spring 5 will be out of shape to release conditions, will promote ejector pin bar 6, pushing slice of nail 7 and cutting knife and move with respect to nail bin 1.Stapler of the present invention can also be provided with one and make button 4 regressive springs, and a wind spring 5 tighten up knob.As shown in Figure 3, this tightens up knob and comprises the axle 12 on a rotating handles 13 and the rotation axis that is vertically set on rotating handles 13, and the end, center of said wind spring 5 is connected on this axle 12.After once operation finished, promptly wind spring 5 was in release conditions, operated rotating handles 13 this moment and made axle 12 rotations; Drive wind spring 5 then and all get back to the initial state that tightens up; This moment, button 4 was also got back to initial position, and promptly the state among Fig. 2 is changed nail bin 1 then and can be carried out seaming and cutting next time.
Accumulating mechanism can also be the bent Metallic rod with memory function except the wind spring in the preferred embodiment, is fixedly connected on the ejector pin bar 6; When initial energy accumulating state; It is arranged on for bending in the shell of stapler, and after the projection 10 of button 4 withdrawed from from recess 9, Metallic rod begins to release can be elongated; Promptly promote ejector pin bar 6, pushing slice of nail 7 and cutting knife and move, accomplish automatic seaming and cutting with respect to nail bin 1.
Accumulating mechanism also can make other form of springs; But because the distortion of spring is very fast, accident surgery might appear, so the stapler inherence is provided with a damping mechanism again; Rubber for example; It is elongated that spring can be out of shape slowly, realizes that ejector pin bar 6, pushing slice of nail 7 and cutting knife move with respect to the slow of nail bin 1, accomplish automatic seaming and cutting.
Accumulating mechanism of the present invention goes for multiple stapler, for example: side side type surgical incision stapler, tubular type stapler etc.; The perhaps anastomat of other types, for example: the linear suture device.All employings are equal to replacement or equivalent transformation and all technical schemes of forming all drop within the scope of requirement protection of the present invention.
