Abstract
The invention discloses a surgical apparatus, which comprises a nail anvil and a nail cabin arranged oppositely, wherein the outer surface of the nail anvil is provided with a nail anvil shell; an insertion hole through which a bolt passes is formed on the nail anvil; the bolt is provided with two annular grooves; an H-shaped four-pin bracket is arranged in the nail anvil; and four pins of the H-shaped four-pin bracket are inserted into the annular grooves. The surgical apparatus has the beneficial effects that a columnar pin on the inner side of the nail anvil shell and a recess correspondingly formed in the surface of the nail anvil form an interference structure, and the annular grooves, the H-shaped four-pin structure and a grab structure on the nail anvil shell cooperate to prevent the bolt from falling off, so that the nail anvil and the nail anvil shell are connected tightly, and are prevented from falling off easily.
Description
Technical field
The present invention relates to a kind of surgical operating instrument, be in particular a kind of linear type seaming and cutting device, belong 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 US Patent No. 5129570 announcement, 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 nail anvil and the nail bin of upper and lower clamp far-end, be located in the nail bin and also can move percussion sheet and cutting knife relative to described nail bin simultaneously, and for driving the push button that described percussion sheet and cutting knife move.Be disposed with suturing nail in the described nail bin, described percussion sheet promotes pushing slice of nail successively in order and pushes suturing nail to nail anvil, and described cutting knife cuts off the tissue between nail bin and nail anvil.
The nail anvil of existing linear type seaming and cutting device is generally metal, its outer surface is installed with a nail anvil shell, but only be that the nail anvil shell is placed on the nail anvil in the prior art, make nail anvil the phenomenon of play up and down when being subjected to clashing into, occur, cause the junction fracture of nail anvil shell and nail anvil, apparatus is damaged.。
Summary of the invention
The objective of the invention is to propose a kind of surgical operating instrument simple in structure, be the linear type seaming and cutting device of nail anvil shell with difficult drop-off.
Purpose of the present invention will be achieved by the following technical programs:
A kind of surgical operating instrument, comprise the nail anvil and the nail bin that are oppositely arranged, described nail anvil outer surface is provided with the nail anvil shell, described nail anvil is provided with one and is used for the jack that a latch passes through, described latch is provided with the bipassage ring connected in star, be provided with a H type four foot supports in the described nail anvil, four feet of described H type four foot supports insert in the described annular groove.
Preferably, described nail anvil shell inboard convexes with a column-shaped projection downwards, the corresponding recess of accommodating described column-shaped projection that is provided with in described nail anvil surface.
Preferably, described nail anvil shell is provided with the trip for the clamping nail anvil.
Preferably, described trip is 4 groups of symmetric arrays.
Beneficial effect of the present invention is mainly reflected in: the corresponding recess that is provided with the nail anvil surface of the cylindrical pin of nail anvil shell inboard forms the interference structure, cannelure and H type four foot support structures, hook structure on the nail anvil shell, coming off of these structure combined effect restriction latches, make nail anvil be connected closely difficult drop-off with the nail anvil shell.
Description of drawings
Fig. 1 is the structural representation of surgical operating instrument of the present invention.
Fig. 2 is along the cutaway view of M-M among Fig. 1.
Fig. 3 is the structure chart of H type four foot supports of the present invention.
Fig. 4 is the structure chart of latch of the present invention.
The specific embodiment
As shown in Figure 1, the invention provides a kind of linear type seaming and cutting device.Consistent with prior art, described linear type seaming and cutting device comprises closure or the last clamp of opening and following clamp mutually, 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.
Described nail anvil 1 outer surface is provided with nail anvil shell 3.Described nail anvil 1 is provided with a jack 4, one latches 5 and inserts in the described jack 4.
Described latch 5 is provided with bipassage ring connected in star 7, is fixed with a H type four foot supports 8 on the described nail anvil 1, and described H type four foot supports 8 are arranged in the through hole of nail anvil 1 and get final product.Four feet of described H type four foot supports 8 are inserted in the described annular groove 7, thereby banking pin comes off.
Described nail anvil 1 shell inboard convexes with a column-shaped projection 9 downwards, the corresponding recess 10 of accommodating described column-shaped projection 9 that is provided with in described nail anvil 1 surface, and described nail anvil shell 1 is symmetrically arranged with four trips 11 that are used for clamping nail anvil 1.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
