Description
Technical field
The present invention relates to 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 U.S. Pat 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 the nail anvil and the nail bin of upper and lower clamp front end, be located in the nail bin and can move ejector pin bar and cutting knife relative to described nail bin simultaneously, and be used to drive the push button that described ejector pin bar and cutting knife move.Be disposed with suturing nail in the described nail bin, described ejector pin bar promotes pushing slice of nail successively in order and pushes suturing nail to nail anvil, and described cutting knife will cut off at the tissue between nail bin and the nail anvil.
The nail bin of this apparatus be can change nonexpondable.When clinical use, often need repeatedly stitching to cut and organize, therefore when operation, need repeatedly change nail bin.Under the situation of not putting into nail bin, push button can be promoted forward arbitrarily, and then cutting knife can be pushed out, and can cause only cutting and unstitched serious consequence.Therefore, the linear type seaming and cutting device of prior art all can be provided with a kind of insurance institution.
U.S. Pat has disclosed a kind of insurance institution No. 5129570, and a safety block that has cutting knife passage and ejector pin bar passage is set at the middle part of apparatus, and shell fragment is set below cutting knife.When apparatus was shown in an open position (being that upper and lower two clamps are not closed), shell fragment was upspring cutting knife, made cutting knife can't pass through the cutting knife passage, played safety effect; When apparatus is loaded onto nail bin, and after upper and lower two clamp closures, nail bin compressing cutting knife top makes cutting knife overcome the elastic force of shell fragment and returns to state with the cutting knife channel alignment, and insurance is at this moment removed, and apparatus can be pulled the trigger use.
U.S. Pat has disclosed another kind of insurance institution No. 7055730, and a safety block that has push broach bar passage and ejector pin bar passage is set at the middle part of apparatus, and this safety block can rotate around apparatus under the torsion spring effect.When apparatus was shown in an open position (being that upper and lower two clamps are not closed), safety block twisted, and made ejector pin bar and push broach bar all can't pass through passage, played safety effect; When apparatus is loaded onto nail bin, and after upper and lower two clamp closures, nail bin compressing safety block make it overcome the elastic force of torsion spring and recover the normal position (be ejector pin bar and push broach bar respectively with its safety block on channel alignment), make ejector pin bar and push broach bar all can pass through safety block, at this moment insurance is removed, and apparatus can be pulled the trigger use.
More than several structures all very complicated, processing assembling difficulty costs an arm and a leg.
Summary of the invention
The objective of the invention is to propose a kind of linear type seaming and cutting device with insurance institution of simple structure.
Purpose of the present invention will be achieved by the following technical programs:
A kind of linear type seaming and cutting device, comprise: can be mutually the closed or upper and lower clamp opened, described clamp down is a ∪ shape, be provided with the ejector pin bar in it slidably, the near-end of described ejector pin bar is connected in a sliding shoe, and described linear type seaming and cutting device also comprises an insurance institution, described insurance institution comprises that a pivot is arranged at the release member on the described clamp down, the far-end of described release member acts on described sliding shoe, thereby makes described linear type seaming and cutting device optionally be in two states
A) safety position: described release member is connected on the described sliding shoe;
B) insurance disarm state: described release member and sliding shoe are separated.
Further, the far-end of described release member is provided with a projection, described sliding shoe is provided with a groove, the optionally clamping or separate of described projection and groove, thus make described linear suture device optionally be in described safety position or insurance disarm state.
Further, the near-end of described release member is arranged at the described near-end of clamp down by a torsion spring and a rotating shaft pivot.
Further, during the insurance disarm state, the axis of described release member is parallel with the axis of described sliding shoe.
Further, the described near-end of going up clamp can drive the near-end of described release member, makes the far-end of release member act on described sliding shoe, thereby makes described linear type seaming and cutting device optionally be in described safety position or insurance disarm state.
Beneficial effect of the present invention is mainly reflected in: simple in structure, easy to process, safe and reliable, and have excellent popularization and be worth.
