Abstract
The utility model discloses a linear suturing and cutting device which comprises a nail anvil and a nail bin that are oppositely arranged, wherein the front end of the nail anvil is provided with a nail anvil cap, the front end face of the nail anvil is provided with a circular hole, the surface of the nail anvil cap, which is opposite to the surface of the nail anvil, is convexly provided with a hollow cylinder, the outer diameter of the hollow cylinder is equal to the inner diameter of the circular hole, at least one long groove is arranged on the wall of the hollow cylinder along the axial line, the top end of the hollow cylinder is provided with a bulge with the diameter more than that of the hollow cylinder, and a groove for containing the bulge is correspondingly arranged in the circular hole of the nail anvil. The utility model has the beneficial effect that the nail anvil cap is more tightly connected with the nail by adopting a special structure of the hollow cylinder, thus the nail anvil cap is effectively prevented from dropping.
Description
Technical field
This utility model relates to a kind of linear type seaming and cutting device, belongs to technical field of medical instruments.
Background technology
Linear type seaming and cutting device is widely used in being used in the surgical operation wound suture, interior tissue is sewed up and cutting; Typical linear type seaming and cutting device such as 5129570 announcements of U.S. Pat; Have and sew up and two functions of cutting, when carrying out wound suture, excess tissue is excised.Such linear type seaming and cutting device generally comprises upper and lower two clamps; And the closed handle that is used for closed upper and lower clamp; Be oppositely arranged on the nail anvil and the nail bin of upper and lower clamp far-end; Be located in the nail bin and can move percussion sheet and cutting knife relative to said nail bin simultaneously, and be used to drive the push button that said percussion sheet and cutting knife move.Be disposed with suturing nail in the said nail bin, said percussion sheet promotes pushing slice of nail successively in order and pushes suturing nail to nail anvil, and said cutting knife will cut off at the tissue between nail bin and the nail anvil.
The nail anvil front end of existing linear type seaming and cutting device generally can be fixed a nail-anvil cap, and both only are that the plug of interference fit connects, and finds that from the process of actual production nail-anvil cap is easy to drop or the connecting portion fracture, especially through after the long-distance transport of jolting.Can make apparatus produce the puzzlement that is not used and promptly scraps like this.
The utility model content
The purpose of this utility model is to propose a kind of linear type seaming and cutting device with nail-anvil cap simple and reliable for structure.
The purpose of this utility model will be achieved through following technical scheme:
A kind of linear type seaming and cutting device; Comprise the nail anvil and the nail bin that are oppositely arranged; The front end of said nail anvil is provided with nail-anvil cap, and the front end face of said nail anvil is provided with a circular hole, and the surface that regards to nail anvil of said nail-anvil cap convexes with a hollow cylinder; The external diameter of said hollow cylinder equals the internal diameter of said circular hole; Its axis of wall upper edge of said hollow cylinder has at least one elongated slot, and the top of said hollow cylinder is the projection of a diameter greater than the hollow cylinder diameter, the corresponding groove that is used to accommodate said projection that is provided with in the circular hole of said nail anvil.
Preferably, the top of the circular hole of said nail anvil offers gathering sill, the corresponding prerotation vane that is provided with on the said nail-anvil cap.
The beneficial effect of this utility model is mainly reflected in: the special construction of hollow cylinder, make to be connected closelyr between nail-anvil cap and the nail anvil, and prevent coming off of nail-anvil cap effectively.
Description of drawings
Fig. 1 is the exploded perspective view of the nail-anvil assembly part of this utility model straight line seaming and cutting device.
Fig. 2 is the cutaway view of this utility model straight line seaming and cutting device nail-anvil assembly.
The specific embodiment
As shown in Figure 1, this utility model provides a kind of linear type seaming and cutting device.Consistent with prior art, said linear type seaming and cutting device comprises closure or last clamp of opening and following clamp each other, and pivot is located at down on the clamp and is used for the closed handle of closed upper and lower clamp, and the far-end of last clamp is provided with nail anvil 1, and the far-end of following clamp is provided with nail bin.
As depicted in figs. 1 and 2; The front end of said nail anvil 1 is provided with nail-anvil cap 4; The front end face of said nail anvil 1 is provided with a circular hole 2; The surface that regards to nail anvil 4 of said nail-anvil cap 4 convexes with a hollow cylinder 5, and the external diameter of said hollow cylinder 5 equals the internal diameter of said circular hole 2, and said hollow cylinder 5 can be inserted in the circular hole 2.
Its axis direction of wall upper edge of said hollow cylinder 5 has at least one elongated slot 8, generally is arranged with the 2-4 bar.The top of said hollow cylinder 5 is the projection 7 of a diameter greater than the hollow cylinder diameter, the corresponding groove 9 that is used to accommodate said projection 7 that is provided with in the circular hole 2 of said nail anvil.In the time of in hollow cylinder 5 can be inserted into circular hole 2 because the diameter of projection 7 is bigger, institute so that hollow cylinder 5 under the effect of elongated slot 8, shrink in the entering circular hole 2, in projection 7 entering grooves 9.
In order to prevent nail-anvil cap 4 rotations, the top of the circular hole 2 of said nail anvil 1 offers gathering sill 3, the corresponding prerotation vane 6 that is provided with on the said nail-anvil cap 4.Like this, in nail-anvil cap 4 is mounted to nail anvil 1 after, prerotation vane 6 is inserted in the gathering sill 3, prevents nail-anvil cap 4 rotation.
This utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of this utility model.
