Description

A kind of minimally invasive pin knife
Technical field
The invention belongs to technical field of medical instruments, and in particular to a kind of minimally invasive pin knife.
Background technology
Needle-knife therapy is on the basis of Chinese acupuncture and moxibustion, to develop formation with reference to modern medicine knife for surgical purpose, be The product organically combined with Soft tissue releasing, is primarily adapted for use in soft tissue injury venereal disease and becomes and osteoarthrosis.
Presently used pin knife is all made up of metal material, in shape like pin again like a kind of pin apparatus of knife, its shape Shape and length are slightly different, general length be 10cm~15cmm, a diameter of 0.4mm~1.2mm, be broadly divided into hand holding handle, The needle body and the part of pin knife three;Pin knife width is equal typically with the cross-sectional diameter of needle body, and cutting edge is sharp, the blade and needle point of pin knife Structure it is entirely different, belong to flat scoop structure, therefore when being pierced into body, its pain degree is naturally larger than isometrical pin Thorn, the pain that especially medium size, the pin knife of large size are caused more so, can also cause larger wound, the convalescence of patient also can It is elongated.
The content of the invention
It is an object of the invention to provide a kind of minimally invasive pin knife, have the advantages that pain is small and wound is small when in use.
The technical solution adopted in the present invention is, a kind of minimally invasive pin knife, including pin cutter hub, and one section of pin cutter hub top upper to cover There is spring, the top of pin cutter hub, which is connected with sliding block, sliding block, is connected with limited post, pin cutter hub is cased with one section and sliding block one of spring Rise and be placed in pin knife cap, L-shaped stopper slot is provided with the cap wall of pin knife cap, limited post is stretched into L-shaped stopper slot, pin cutter hub is remaining One section be placed in pin broach shell pipe, and pin cutter hub and pin broach shell pipe internal clearance coordinate and can slided, pin knife cap and pin broach shell Guan Lian Connect, the lower end of pin broach shell pipe is pierced into end for point of a knife, and end is pierced into point of a knife and offer the outlet of pin cutter hub, regulation limited post is in L-shaped Position in stopper slot can make pin cutter hub along pin knife cannula slide and export from pin cutter hub to send out or withdraw.
The features of the present invention is also resided in:
Limited post is welded on sliding block.
The diameter of sliding block is not less than the internal diameter of spring.
Continuous external screw thread is provided with the outside of pin knife cannula tip, pin knife cap lower inside is provided with continuous internal thread, Pin broach shell Guan Yuzhen knife caps are connected by internal and external threads.
L-shaped stopper slot is connected and composed by stopper slot A and stopper slot B, forms L shapes.
The beneficial effects of the invention are as follows:The minimally invasive pin knife of the present invention, by setting pin broach shell pipe and matching somebody with somebody in its internal clearance The pin cutter hub slided is closed, pin edge is hidden using hollow needle-like sleeve pipe, the sharp spine of sharp cannula is relied on when entering human body Enter, into after human body, then extrude pin cutter hub, implement loosening therapy, solve wound present in existing pin knife treatment greatly, implement Pain, the problem of convalescence is long, pain is small when using and wound is small.

Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of minimally invasive pin knife of the present invention, as shown in Figure 1, Figure 2 and Figure 3, including pin cutter hub 1, on one section of the top of pin cutter hub 1 Spring 3 is cased with, the top of pin cutter hub 1 is connected with connection on sliding block 7, sliding block 7 (affixed, such as to weld form) limited location post 5, should The diameter of sliding block 7 is not less than the internal diameter of spring 3, and pin cutter hub 1 is cased with one section of spring 3 and sliding block 7 is placed in pin knife cap 4 together, L-shaped stopper slot 6 is provided with the cap wall of pin knife cap 4, limited post 5 is stretched into L-shaped stopper slot 6,1 remaining one section of pin cutter hub is placed on In pin broach shell pipe 2, and pin cutter hub 1 coordinates with the internal clearance of pin broach shell pipe 2 and can slided, and pin knife cap 4 is connected with pin broach shell pipe 2, pin The lower end of broach shell pipe 2 is that point of a knife is pierced into end, and offers the outlet of pin cutter hub at point of a knife piercing end, and regulation limited post 5 is spacing in L-shaped Position in groove 6 can make pin cutter hub 1 be slided along pin broach shell pipe 2 and export submitting from pin cutter hub or withdraw.
The top outer of pin broach shell pipe 2 is provided with continuous external screw thread, and the lower inside of pin knife cap 4 is provided with spiral shell in continuous Line, pin broach shell pipe 2 is connected with pin knife cap 4 by internal and external threads.
As shown in figure 4, L-shaped stopper slot 6 is connected and composed by B 6-2 of A 6-1 of stopper slot and stopper slot, L shapes are formed.
A kind of application method of minimally invasive pin knife of the present invention is:Limited post 5 is placed in L-shaped stopper slot 6 stopper slot A first 6-1 position, now spring 3 is in normal state, and this hour hands cutter hub 1 is hidden inside pin broach shell pipe 2 completely;To suffering from When person applies pin, to be pierced into terminal spine by the sharp point of a knife in 2 bottoms of pin broach shell pipe and enter human body, after treatment depth is entered, stop Point of a knife is pierced into the piercing at end, and the position that limited post 5 is placed in into stopper slot B 6-2 in L-shaped stopper slot 6 is locked, now at spring 3 In compressive state, the pin cutter hub that the flat edge of pin cutter hub 1 is just pierced into end from point of a knife, which is exported, to be stretched out, and doctor can just put lytic needle knife to good use Gimmick is treated;After the completion of to be treated, then limited post 5 is returned to A 6-1 of pin stopper slot position, spring 3 is upspring, pin knife Body 1 is withdrawn, and the point of a knife for then extracting pin broach shell pipe 2 is pierced into end.
A kind of minimally invasive pin knife of the present invention is by setting pin broach shell pipe 2 and coordinating the pin cutter hub 1 slided in its internal clearance, i.e., Pin edge is hidden using hollow needle-like sleeve pipe, is pierced into when entering human body by the sharp point of a knife in 2 lower ends of pin broach shell pipe Terminal spine enters human body, after into human body, then extrudes the pin cutter hub 1 in pin broach shell pipe 2, implements loosening therapy, solves existing pin Wound present in knife treatment is big, implements pain, and the problem of convalescence is long, operation is also very simple, when using pain it is small and Wound is small.
