Abstract
The invention discloses a linear suturing and cutting instrument, which comprises a nail anvil and a nail bin arranged relatively, wherein a nail anvil shell is arranged on the outer surface of the nail anvil; and at least one bulge for connecting the nail anvil in a clamping way, and limiting the nail anvil and the nail anvil shell to move along the axial direction is arranged in the nail anvil shell. The linear suturing and cutting instrument has the beneficial effects that a bulge positioning structure is added, so that the nail anvil is prevented from moving front and back under exogenic action so as to cause the fragmentation of a pin hole, and meanwhile, the occurrence of the phenomenon that the nail anvil shell is separated from the instrument due to the breakage of the connecting part of the nail anvil shell and the nail anvil under the exogenic action can be effectively prevented.
Description
Technical field
The present invention relates to a kind of straight line sewing and cutting machine, belong to technical field of medical instruments.
Background technology
The straight line sewing and cutting machine is widely used in being used in the surgical operation wound suture, interior tissue is sewed up and cutting, typical straight line sewing and cutting machine 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 straight line sewing and cutting machine 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 straight line sewing and cutting machine is generally metal structure, can fix a nail anvil shell at its outer surface, but only be to utilize brace to be connected in the outside of nail anvil on the nail anvil shell in the prior art, there is not corresponding location structure, make nail anvil when being clashed into or fall, because the phenomenon of play about occurring between nail anvil and the nail anvil shell, thereby the connecting portion of nail anvil and nail anvil shell is ruptured easily, thereby apparatus is not used and scrap.
Summary of the invention
The objective of the invention is to propose a kind of simple in structure, safe straight line sewing and cutting machine.
Purpose of the present invention will be achieved by the following technical programs:
A kind of straight line sewing and cutting machine comprises the nail anvil and the nail bin that are oppositely arranged, and the outer surface of described nail anvil is provided with the nail anvil shell, and described nail anvil enclosure arranges at least one and is used for the clamping nail anvil and limits nail anvil and projection that described nail anvil housing axis moves.
Preferably, described nail anvil enclosure is provided with prelocalization projection and the back positioning convex that lays respectively at nail anvil shell front and back end, and described prelocalization projection is connected in the opening of described nail anvil, and described back positioning convex is connected to the tail end of described nail anvil.
Preferably, be equipped with reinforcement on described prelocalization projection and the nail anvil shell brace.
Beneficial effect of the present invention is mainly reflected in: increase protruding location structure, prevent play and make pin-and-hole cracked before and after nail anvil under external force, effectively prevent the nail anvil shell simultaneously under external force owing to break away from the situation generation of apparatus with the junction fracture of nail anvil.
Description of drawings
Fig. 1 is the nail anvil of straight line seaming and cutting device of the present invention and the cutaway view of nail anvil casing assembly part.
Fig. 2 is the upward view of straight line seaming and cutting device nail anvil shell of the present invention.
The specific embodiment
As shown in Figure 1, the invention provides a kind of straight line sewing and cutting machine.Consistent with prior art, described straight line sewing and cutting machine 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, and the far-end of following clamp is provided with nail bin.
As depicted in figs. 1 and 2, described nail anvil 1 outer surface is provided with nail anvil shell 2, and described nail anvil 1 front end is provided with for the opening 3 that connects nail anvil shell 2, and described nail anvil 1 rear end is provided with the pin-and-hole of accommodating latch 4.
Be set with two location on the described nail anvil shell 2 and strengthen projection, i.e. prelocalization projection 6 and back positioning convex 7, described prelocalization projection 6 is connected in the opening 3 of described nail anvil, and described back positioning convex 7 is connected to the tail end of described nail anvil.Described prelocalization projection 6 and described back positioning convex 7 are located jointly; with strengthen nail anvil shell and nail anvil apparatus axis to fixed-site, when being subjected to external force collision, also can share the power of bearing on the brace 5; effectively the safety of protection brace 5 and pin 9 is stablized connection.
Preferably, also be provided with reinforcement 8 on described prelocalization projection 6 and the brace 5, for increasing the intensity of nail anvil shell 2 self.
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.
