Technical field
The present invention relates to a kind of surgical operation sewing and cutting machine, belong to technical field of medical instruments.
Background technology
The surgery sewing and cutting machine is widely used in being used in the surgical operation wound suture, interior tissue is sewed up and cutting, typical surgery sewing and cutting machine such as U.S. Pat 5065929 announcement, have and sew up and two functions of cutting, when carrying out wound suture, excess tissue is excised.As shown in Figure 1, such sewing and cutting machine generally comprises upper and lower clamp 4,5, the closed handle 6 that is used for closed upper and lower clamp, be oppositely arranged on the nail anvil 7 and the nail bin 8 of clamp front end up and down, be located in the nail bin 8 and the pushing slice of nail and the cutting knife 9 that can move relative to described nail bin simultaneously, and drive percussion sheet and the push broach bar 2 that pushing slice of nail and cutting knife move, be disposed with suturing nail in the described nail bin, described pushing slice of nail is pushed suturing nail to nail anvil, and described cutting knife 9 will cut off at the tissue between nail bin and the nail anvil.
As shown in Figure 2, push broach bar 2 passes a push broach frame 3, and push broach bar 2 meeting in the process of sliding produces friction with this slide block 1, so the doctor needs bigger driving force to order about 2 slips of push broach bar in operation.After seaming and cutting were finished, push broach bar 2 can drive cutting knifes 9 and slide backward, and when cutting knife 9 slides into when abutting to push broach frame 3, push broach bar 2 will stop to slide, and guarantees that push broach bar 2 can not skid off from the push broach frame.But owing to make and assembling, the frictional force between push broach bar 2 and the slide block 1 is bigger, and making slide block 1 drive push broach bar 2 can skid off from push broach frame 3, thereby influences the percussion once more of apparatus.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, the scheme of guaranteeing that the push broach bar can not skid off in the process that retreats from the push broach frame is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of sewing and cutting machine, comprise, following clamp, be oppositely arranged on, the nail bin of following clamp front end and nail anvil, the pushing slice of nail and the cutting knife that can move relative to described nail bin, and drive percussion sheet and the push broach bar that described pushing slice of nail and cutting knife move, be disposed with suturing nail in the described nail bin, described percussion sheet drives described pushing slice of nail and pushes suturing nail to nail anvil, described cutting knife will cut off at the tissue between nail bin and the nail anvil in the process that it moves, described push broach bar comprises a bottom surface and first end face, second end face, between described second end face and first end face difference in height is arranged, described first end face arrives the distance of bottom surface greater than described second end face to the distance of bottom surface.
Further, be provided with a recess between second end face of described push broach bar and first end face.
Further, the bottom surface of described push broach bar is provided with a underside recess.
Further, described push broach bar passes the tool slot of a push broach frame, is provided with a upper convex portion and following protuberance in the described tool slot, when described push broach frame rotates, and described upper convex portion and recess butt, described protuberance and underside recess butt down.
Further, the outside of described push broach frame is provided with a rotating shaft, and described push broach frame rotates around described rotating shaft.
Beneficial effect of the present invention is mainly reflected in: instrumentation is simple, forms big drop between push broach bar and the push broach frame, guarantees that the push broach bar can not skid off in the process that retreats, thereby guarantee the serviceability and the safety of apparatus from the push broach frame.

The specific embodiment
The present invention has disclosed a kind of surgery sewing and cutting machine, and is consistent with prior art as shown in Figure 1, comprises that 4,5 and pivots of upper and lower clamp are arranged on down the closed handle 6 on the clamp 5.The described front end of going up clamp 4 is provided with nail anvil 7, and the front end of following clamp 5 is oppositely arranged nail bin 8.Described closed handle 6 can be moved between open position and make position, and when closed handle 6 was shown in an open position, upper and lower clamp 4,5 was in the position of opening relatively; When closed handle 6 was in the close position, upper and lower clamp 4,5 was in sufficiently closed position, and can carry out seaming and cutting this moment.
The same with prior art, described sewing and cutting machine also comprises the pushing slice of nail and the cutting knife that can move relative to described nail bin 8, and drive percussion sheet and the push broach bar 2 that described pushing slice of nail and cutting knife 9 move, be disposed with suturing nail in the described nail bin 8, described percussion sheet drives described pushing slice of nail and pushes suturing nail to nail anvil 7, and described cutting knife 9 will cut off at the tissue between nail bin 8 and the nail anvil 7 in the process that it moves.
To shown in Figure 5, described push broach bar 2 comprises a rear end 21 and a front end 22 in conjunction with Fig. 2, fixedlys connected with slide block 1 in described its rear end 21, and described slide block 1 drives push broach bar 2 front and back and slides.Be fixed with cutting knife 9 on described its front end 22.
Described push broach bar 2 comprises a bottom surface 26 and first end face 23, second end face 24, between described second end face 24 and first end face 23 height difference H is arranged, described first end face 23 to the distance of bottom surface 26 greater than the distance of described second end face 24 to bottom surface 26.Be provided with a recess 25 between second end face 24 of described push broach bar 2 and first end face 23.The bottom surface 26 of described push broach bar 2 is provided with a underside recess 27.
When sewing and cutting machine is positioned at original state, be provided with a push broach frame 3 at front end 22 places of push broach bar 2, described push broach bar 2 passes the tool slot 31 of this push broach frame 3.During original state, first end face 23 arrives on the end face of this tool slot 31.In the sewing and cutting machine work process, push broach bar 2 is when front slide, because the height of aspect ratio first end face 23 of second end face 24 is low, thus second end face 24 can not arrive on the end face of this tool slot 31, so just reduced friction between push broach bar 2 and the push broach frame 3.
In conjunction with Fig. 5 and shown in Figure 6, be provided with a upper convex portion 32 and following protuberance 33 in the tool slot 31 of described push broach frame 3, the outside of described push broach frame 3 is provided with a rotating shaft 34, and when push broach bar 2 retreated, described push broach frame 3 can rotate around described rotating shaft 34.When described push broach frame 3 rotates, recess 25 butts of described upper convex portion 32 and push broach bar 2, underside recess 27 butts of described protuberance 33 down and push broach bar 2 make push broach bar 2 can not skid off from push broach frame 3 like this.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
