Description
Technical field
The present invention relates to a kind of Linear seam cutting device, relate in particular to a kind of insurance institution 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, described cutting knife is fixed in the far-end of a push broach bar, and is used for driving the push button that described percussion sheet and push broach bar 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.
Existing Linear seam cutting device can first be sewed up afterwards when guaranteeing to perform the operation and cut and organize, and when being designed to promote push button, the percussion sector-meeting is first sewed up with the push button segment distance that advances, and then push button promotes the push broach bar again and advances and cut.So existing push broach bar arranges one section neutral gear at its near-end, guarantee first to allow the percussion sheet move forward one section distance identical with neutral gear on the push broach bar, and then move forward together with the push broach bar.
Existing apparatus is provided with on nail bin and protects the nail sheet when encapsulation, guarantees that suturing nail is maintained in nail bin on the one hand, on the other hand, protects the nail sheet and props up blade, and cutting knife is fixed at the non-working condition upper/lower positions.But existing apparatus is not before using, only protect the nail sheet and playing safety effect, push button is when the quilt accident promotes forward so, the percussion sheet can move forward a segment distance, and mobile distance just is arranged on the length of neutral gear on the push broach bar, causes apparatus also formally not used, in nail bin, several of near-end suturing nails just are pushed out, advance together with the push broach bar until push button passes neutral gear, and be subject to protecting stopping of nail sheet, just can stop moving forward.In a single day such situation occurs, and apparatus is just scrapped.
Summary of the invention
The objective of the invention is to propose a kind of Linear seam cutting device with insurance institution of simple structure.
Purpose of the present invention will be achieved by the following technical programs:
a kind of insurance institution that is applicable to Linear seam cutting device, described Linear seam cutting device comprise can be mutually closed or open upper, lower clamp, pivot is located on lower clamp and is used for closure, the closed handle of lower clamp, be oppositely arranged on, the nail anvil of lower clamp far-end and nail bin, the percussion sheet of being located in nail bin and can moving relative to described nail bin, push broach bar and cutting knife, and be used for driving the push button that described percussion sheet and push broach bar move, described push button connects and promotes a slide block, described slide block is mutually permanently connected with the percussion sheet, described slide block and push broach bar are slidably connected, be located at the guide pillar that a slip is coupled to described slide block inside on described push broach bar, also be provided with one away from the step of guide pillar on described push broach bar, it is neutral gear between described guide pillar and step, the end face of described slide block drives step moves described push broach bar.The described insurance institution that is applicable to Linear seam cutting device is a fixed block, and the length along push broach rod axis direction of described fixed block equals the length along push broach rod axis direction of described neutral gear.
Preferably, described fixed block is connected in described neutral gear.
Preferably, described fixed block comprises three passages, is respectively the both wings of percussion sheet and the passage of push broach bar.
Preferably, the top of described fixed block is provided with a grasping part.
Beneficial effect of the present invention is mainly reflected in: simple in structure, safe and reliable, have good promotional value.
Description of drawings
Fig. 1 is the schematic diagram of Linear stapling cutter of the present invention.
Fig. 2 is the exploded perspective view of Linear stapling cutter of the present invention, has saved subelement.
The specific embodiment
As shown in Figure 1, the invention provides a kind of insurance institution that is applicable to Linear seam cutting device.Consistent with prior art, as depicted in figs. 1 and 2, described Linear seam cutting device comprises cabinet 1, can be mutually closed or upper clamp 2 and the lower clamp 3 opened, pivot is located on lower clamp and is used for the closed handle 6 of closed upper and lower clamp, the far-end of upper clamp 2 is provided with nail anvil 4, and the far-end of lower clamp 3 is provided with nail bin 5.Certainly, the position of up and down clamp can exchange, just the present invention is in order to express clearly so definition.
Described lower clamp 3 is ∪ shape, is provided with slidably the cutting knife (not shown) of pulling the trigger sheet 7, push broach bar 8 and being positioned at push broach bar far-end in it, is respectively used to pull the trigger pushing slice of nail and cuts and organizes.The near-end of described upper clamp 2 and lower clamp 3 is provided with and drives the push button 9 that described percussion sheet 7 and push broach bar 8 move, and described push button 9 connects and promotes a slide block 10, described slide block 10 with pull the trigger sheet 7 and be mutually permanently connected.Described slide block 10 is slidably connected with push broach bar 8, be specially: be located at the guide pillar 11 in the elongated slot that a slip is coupled to described slide block 10 inside on described push broach bar 8, also be provided with one on described push broach bar away from the step 12 of guide pillar, be neutral gear 13 between described guide pillar 11 and step 12, the end face 14 of described slide block drives step 12 moves described push broach bar.
Characteristics of the present invention are: the push broach bar of described Linear seam cutting device is provided with an insurance institution, and described insurance institution is a fixed block 15, and the length along push broach rod axis direction of described fixed block equals the length along push broach rod axis direction of described neutral gear.Like this, described fixed block 15 just can be connected in described neutral gear 13.Described fixed block comprises three passages 16, is respectively the both wings of percussion sheet and the passage of push broach bar.The top of described fixed block is provided with a grasping part 17.
When apparatus before use, described fixed block 15 is connected in described neutral gear 13, fixed block 15 end face is resisted against on step 12, another relative end face is resisted against on slide block 10, like this because the position of push broach bar 8 relative up and down clamp under the effect of protecting the nail sheet is fixed, this is due to the effect of fixed block 15, cause slide block 10 relatively also to be fixed the position of up and down clamp, like this with the fixing percussion sheet 7 of this slide block 10 also just relative up and down clamp fix, like this with regard to not producing that percussion sheet 7 is moved unintentionally and with the situation of suturing nail release.
When using apparatus, at first open apparatus, then tissue is placed between nail anvil 4 and nail bin 5, then take fixed block 15 away, involutory upper and lower clamp 2,3 is pressed closed handle 6, makes upper and lower clamp grip tissue; Then promote push button 9, the stitching that can implement to organize and cutting.
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.
