Description

Linear type seaming and cutting device
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 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 the equal more complicated of several structures, processing assembling difficulty costs an arm and a leg.

Further, described safety piece is a shell fragment, and the insurance auxiliary section of described ejector pin bar is for accommodating the draw-in groove of this shell fragment.
Further, described shell fragment comprises that is used for a movable end that is driven by described nail bin, and one be used for and the described fixed stiff end of clamp down, and described movable end stretches in the draw-in groove of described ejector pin bar.
Further, described stiff end is welded in the described medial surface of clamp down.
Further, the lateral wall of described nail bin is for driving the actuator that described shell fragment breaks away from from the draw-in groove of described ejector pin bar.
Further, the distance between two medial walls of distance between two of described nail bin lateral walls and described clamp down is suitable.
Further, the lateral wall of described nail bin is a lozenges.
The beneficial effects of the utility model are mainly reflected in: simple in structure, easy to process, safe and reliable, and have excellent popularization and be worth.

The specific embodiment
As shown in Figure 1, this utility model provides a kind of insurance institution of linear type seaming and cutting device.Consistent with prior art, described linear type seaming and cutting device comprises cabinet, can be mutually the closed or upper and lower clamp opened, the far-end of last clamp is provided with the nail anvil (not shown), the far-end of following clamp 1 is provided with nail bin 2.Certainly, the position of clamp can exchange up and down, just this utility model is in order to express clearly so definition.
Described clamp 1 down is a ∪ shape, and its far-end is provided with ejector pin bar 5 and push broach bar (not shown) slidably, is respectively applied for the percussion pushing slice of nail and comes the seaming and cutting tissue with the percussion cutting knife.During use, tissue is placed between nail anvil and the nail bin, involutory then upper and lower clamp, closed handle makes upper and lower clamp grip tissue, promotes to be arranged on the percussion push button of clamp near-end up and down then, the stitching that can implement to organize and cutting.
Characteristics of the present utility model are: be provided with an insurance institution between the ejector pin bar 5 of described linear type seaming and cutting device and the following clamp 1.Described insurance institution comprises that one is arranged at the safety piece on the described clamp down, and the insurance auxiliary section of relative set on described ejector pin bar.In this preferred embodiment, described safety piece is a shell fragment 4, and the insurance auxiliary section of described ejector pin bar 5 is for accommodating the draw-in groove 52 of this shell fragment.As can see from Figure 1, described draw-in groove 52 is close to the percussion end 51 of described ejector pin bar 5 far-ends.
In conjunction with shown in Figure 2, described shell fragment 4 comprises that one is used for by the movable end 42 of described nail bin 2 drivings, and one is used for and described clamp 1 fixed stiff end 41 down.Further, described movable end 42 stretches in the draw-in groove 52 of described ejector pin bar 5, is used to limit described ejector pin bar moving axially with respect to following clamp.Described stiff end 41 is welded in the described medial surface 11 of clamp 1 down.Include two shell fragments 4 in this preferred embodiment, be symmetrically set in respectively on the medial wall 11 of the described both sides of clamp 1 down, corresponding, described ejector pin bar 5 is located at symmetric two draw-in grooves 52.
In conjunction with shown in Figure 3, in this utility model, the lateral wall 21 of described nail bin 2 is for driving the actuator that described shell fragment 4 breaks away from from the draw-in groove 52 of described ejector pin bar 5.When nail bin 2 was not installed, the movable end 42 of described shell fragment 4 stretched in the draw-in groove 52 of described ejector pin bar 5, was used to limit described ejector pin bar with respect to what play clamp and moved axially both relative clampings.Behind the nail bin 2 of packing into, the described shell fragment 4 of lateral wall 21 compressings of nail bin 2 breaks away from the movable end 42 of described shell fragment 4 from the draw-in groove 52 of described ejector pin bar 5, and then described ejector pin bar 5 and following clamp 1 are broken away from, and both can move to axial.Further, in order to realize This move better, the distance between two medial walls 11 of distance between two lateral walls 21 of described nail bin 2 and described clamp 1 down is roughly suitable.Further, more easily enter into the described inside of clamp 1 down in order to make nail bin 2, the lateral wall 21 of described nail bin 2 is set to lozenges.
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 the present utility model.
