Description
Technical field
The present invention relates to a kind of surgical operation Linear seam cutting device, belong to technical field of medical instruments.
Background technology
Surgical operation Linear seam cutting device is widely used in sewing up and cutting for wound suture, interior tissue in surgical operation, typical Linear seam cutting device as US Patent No. 5129570 disclose, have and sew up and cutting two functions, while carrying out wound suture, by unnecessary cutting tissue.Such Linear seam cutting device generally comprises upper and lower two clamps, and for closing the closed handle of 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 also can move percussion sheet and cutting knife relative to described nail bin simultaneously, described cutting knife is fixed on the far-end of a push broach bar, and for driving the push button of described percussion sheet and the movement of push broach bar.Be disposed with suturing nail in described nail bin, described percussion sheet promotes pushing slice of nail in order successively and pushes suturing nail to nail anvil, and the tissue between nail bin and nail anvil cuts off by described cutting knife.
Existing Linear seam cutting device is for first sewing up and cut and organize afterwards when guaranteeing operation, and when being all designed to promote push button, percussion sector-meeting is first sewed up with the push button segment distance that advances, and then push broach bar is just pushed forward and cuts.So existing push broach bar arranges one section of neutral gear at its near-end, ensure first to allow percussion sheet move forward one section of distance identical with neutral gear on push broach bar, and then move forward together with push broach bar.
Existing apparatus, when encapsulating, nail bin is provided with and protects nail sheet, ensures that suturing nail is maintained in nail bin on the one hand, on the other hand, protects nail sheet and props up blade, make cutting knife be fixing at non-working condition upper/lower positions.But existing apparatus is not before using, only protect nail sheet and play safety effect, so push button is when by unexpected driven forward, percussion sheet can move forward a segment distance, and the distance of movement is exactly the length being arranged on neutral gear on push broach bar, causes apparatus also formally not used, in nail bin, several suturing nails of near-end are just pushed out, until push button advances through neutral gear together with push broach bar, and be subject to the stop protecting nail sheet, just can stop moving forward.Such situation is once occur, and apparatus is just scrapped.
Summary of the invention
The object of the invention is to propose a kind of Linear seam cutting device with the insurance institution of simple structure.
Object of the present invention, will be achieved by the following technical programs:
A kind of surgical operation Linear seam cutting device, comprise can mutually close or open upper, lower clamp, pivot to be located on lower clamp and for closed, the closed handle of lower clamp, be oppositely arranged on, the nail anvil of lower clamp far-end and nail bin, and the push button for pulling the trigger, described push button connects and promotes a slide block, described Linear seam cutting device also comprises an insurance institution for slide block described in clamping, described insurance institution comprises a button release, described button release slides and is provided with barb-shaped slide block, the bayonet arrangement connected with described slide block is provided with in described slide block.
Preferably, described button release with between slide block for oat tail groove structure coordinates.
Preferably, be provided with spring between described button release and lower clamp, described button release is connected in when initial position on described lower clamp.
Beneficial effect of the present invention is mainly reflected in: structure is simple, safe and reliable, has good promotional value.

Detailed description of the invention
As shown in Figure 1, the invention provides a kind of insurance institution being applicable to surgical operation Linear seam cutting device.Consistent with prior art, as depicted in figs. 1 and 2, described surgical operation Linear seam cutting device comprises cabinet 1, the upper clamp 2 that can mutually close or open and lower clamp 3, pivot to be located on lower clamp and 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 upper and lower clamp can exchange, just the present invention so defines to express clearly.
Described lower clamp 3 is ∪ shape, is provided with the cutting knife (not shown) of pulling the trigger sheet 7, push broach bar 8 and being positioned at push broach bar 8 far-end slidably, is respectively used to percussion pushing slice of nail and cuts and organizes in it.The near-end of described upper clamp 2 and lower clamp 3 is provided with the push button 9 driving described percussion sheet 7 and push broach bar 8 movement, and described push button 9 connects and promotes a slide block 10, and described slide block 10 is mutually permanently connected with percussion sheet 7.Described slide block 10 is slidably connected with push broach bar 8, be specially: described push broach bar 8 is located at a slip and is coupled to guide pillar 11 in an elongated slot of described slide block 10 inside, described push broach bar being also provided with a step 12 away from guide pillar, is neutral gear 13 between described guide pillar 11 and step 12.
When promoting push button 9, percussion sheet 7 can first be sewed up with the distance that push button 9 advance one section is identical with neutral gear 13 on push broach bar 8, then push button 9 promotes push broach bar 8 again and advances together with cutting knife and cut, and namely the end face 14 of described slide block drives step 12 that described push broach bar 8 is moved.
Feature of the present invention is: described Linear seam cutting device also comprises an insurance institution for slide block described in clamping, described insurance institution comprises a button release 15, described button release 15 slides and is provided with barb-shaped slide block 16, adopt oat tail groove structure to coordinate between the two.The bayonet arrangement connected with described slide block 16 is provided with in described slide block 10.Be provided with spring 17 between described button release 15 and lower clamp 3, described button release is connected in when initial position on described lower clamp 3.The trigger mechanism of described button release is the end face of closed handle 6.
When apparatus is in the initial position shown in Fig. 3, described button release is connected on described lower clamp 3.Now, slide block 16 extend in the bayonet arrangement in slide block 10, and the position of such slide block 10 is just relatively fixing, can not be pushed forward.When then using, pressing button release, button release travels forward relative to apparatus, and apparatus can be opened, and now slide block is under the stop of closed handle 6, moves backward relative to release-push.Be placed on by tissue between nail anvil 4 and nail bin 5, then involutory upper and lower clamp 2,3, presses closed handle 6, makes upper and lower clamp grip tissue; Now, because slide block moves backward relative to button release above, when button release release apparatus is complete under the effect of Compress Spring 17, return to initial position time, slide block has been positioned at the rear of slide block, as shown in Figure 4, at this moment slide block 16 just exits in the bayonet arrangement of slide block 10, and such slide block 10, can be freely movable no longer by the restriction of slide block.Then promote push button 9, stitching and the cutting of tissue can be implemented.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
