Abstract
The invention discloses a linear type suturing and cutting machine. The linear type suturing and cutting machine comprises a nail anvil and a nail bin, which are oppositely arranged, wherein a nail anvil cap is arranged at the front end of the nail anvil; a circular hole is formed in the front end face of the nail anvil; a hollow cylinder is protruded on the surface of the nail anvil cap, which faces the nail anvil; the outer diameter of the hollow cylinder is equal to the inner diameter of the circular hole; at least one elongated groove is formed in the wall of the hollow cylinder along the axis of the hollow cylinder; the top of the hollow cylinder is provided with a protrusion of which the diameter is greater than that of the hollow cylinder; and a groove for accommodating the protrusion is correspondingly formed in the circular hole of the nail anvil. The linear type suturing and cutting machine has the beneficial effects that by the adoption of a special structure of the hollow cylinder, the nail anvil cap is connected with the nail anvil more tightly, and the falling of the nail anvil cap is effectively prevented.
Description
Technical field
The present invention relates to a kind of Linear seam cutting device, belong to technical field of medical instruments.
Background technology
Linear seam cutting device is widely used in being used in surgical operation wound suture, interior tissue is sewed up and cutting, typical Linear seam cutting device such as US Patent No. 5129570 announcement, have and sew up and two functions of cutting, when carrying out wound suture, with unnecessary cutting tissue.Such Linear seam 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 nail anvil and the nail bin of upper and lower clamp far-end, be located in nail bin and can move percussion sheet and cutting knife relative to described nail bin simultaneously, and being used for driving the push button that described percussion sheet and cutting knife move.Be disposed with suturing nail in described nail bin, described percussion sheet promotes in order successively pushing slice of nail and pushes suturing nail to nail anvil, and described cutting knife cuts off the tissue between nail bin and nail anvil.
The nail anvil front end of existing Linear seam cutting device generally can be fixed a nail-anvil cap, and both are only 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 like this apparatus produce the puzzlement that is not used and namely scraps.
Summary of the invention
The objective of the invention is to propose a kind of Linear seam cutting device with nail-anvil cap simple and reliable for structure.
Purpose of the present invention will be achieved by the following technical programs:
A kind of Linear seam cutting device, comprise the nail anvil and the nail bin that are oppositely arranged, the front end of described nail anvil is provided with nail-anvil cap, the front end face of described nail anvil is provided with a circular hole, the surface that regards to nail anvil of described nail-anvil cap convexes with a hollow cylinder, the external diameter of described hollow cylinder equals the internal diameter of described circular hole, have at least one elongated slot along its axis on the wall of described hollow cylinder, the top of described hollow cylinder be a diameter greater than the projection of hollow cylinder diameter, corresponding being provided be used to the groove of accommodating described projection in the circular hole of described nail anvil.
Preferably, the top of the circular hole of described nail anvil offers gathering sill, the corresponding prerotation vane that is provided with on described nail-anvil cap.
Beneficial effect of the present invention is mainly reflected in: the special construction of hollow cylinder, make to be connected closelyr between nail-anvil cap and nail anvil, and effectively prevent coming off of nail-anvil cap.
Description of drawings
Fig. 1 is the exploded perspective view of the nail-anvil assembly part of Linear stapling cutter of the present invention.
Fig. 2 is the cutaway view of Linear stapling cutter nail-anvil assembly of the present invention.
The specific embodiment
As shown in Figure 1, the invention provides a kind of Linear seam cutting device.Consistent with prior art, described Linear seam cutting device comprise can be mutually closed or upper clamp and the lower clamp opened, pivot is located on lower clamp and is used for the closed handle of closed upper and lower clamp, the far-end of upper clamp is provided with nail anvil 1, the far-end of lower clamp is provided with nail bin.
As depicted in figs. 1 and 2, the front end of described nail anvil 1 is provided with nail-anvil cap 4, the front end face of described nail anvil 1 is provided with a circular hole 2, the surface that regards to nail anvil 4 of described nail-anvil cap 4 convexes with a hollow cylinder 5, the external diameter of described hollow cylinder 5 equals the internal diameter of described circular hole 2, and described hollow cylinder 5 can be inserted in circular hole 2.
Have at least one elongated slot 8 along its axis direction on the wall of described hollow cylinder 5, generally be arranged with the 2-4 bar.The top of described hollow cylinder 5 be a diameter greater than the projection 7 of hollow cylinder diameter, interior corresponding being provided be used to the groove 9 of accommodating described projection 7 of the circular hole 2 of described nail anvil.When hollow cylinder 5 can be inserted into circular hole 2 when interior, because the diameter of projection 7 is larger, so that hollow cylinder 5 shrinks under the effect of elongated slot 8 enters in circular hole 2, until projection 7 enters in groove 9.
In order to prevent nail-anvil cap 4 rotations, the top of the circular hole 2 of described nail anvil 1 offers gathering sill 3, the corresponding prerotation vane 6 that is provided with on described nail-anvil cap 4.Like this, when nail-anvil cap 4 be mounted to nail anvil 1 interior after, prerotation vane 6 is inserted in gathering sill 3, prevents nail-anvil cap 4 rotation.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection scope of the present invention.
Claims (2)
