Position lever 192 is located at outside the draw-in groove 182.Specifically, by setting locating support 18 and postive stop baffle 19 on base 12,
When not needing blade 151 to stretch out, positioning lever 192 will be stuck in the draw-in groove 182 of locating support 18, so that locating support 18
Maintain static, locating support 18 moves up the push rod 143 below limitation, so that it is guaranteed that blade 151 can not be exposed at the edge of a knife
Outside 111, realization carries out locking to blade 111, it is ensured that when puncturing, and puncturing conehead 11 will not cause blade because frictional force is excessive
151 expose, and are more beneficial for improving security；And when needing blade 151 to be cut, medical personnel apply by block 13
Pressure, pin 182 will be resisted against on fixed lid 631, so that positioning lever 192 is separated from draw-in groove 182, and now, it is fixed
Position support 18 will apply pressure to postive stop baffle 19 simultaneously so that postive stop baffle 19 bends, so that limited block 142 is from spacing
Groove 191 is detached, and is punctured conehead 11 and is moved drive connecting cylinder 14 by after resistance so that blade 151 stretches out the edge of a knife 111.Wherein,
Locating support 18 can be U-shape structure, and the locating support 18 is enclosed within the outside of the connecting cylinder 14, in order to overall package.
Further, for the ease of assembly and disassembly, also set up between the connecting cylinder 14 and the puncture conehead 11
There is connecting tube 17.Specifically, connecting tube 17 is fastened with the connecting cylinder 14 and the puncture conehead 11 respectively, in assembling
During with dismounting, operating personnel are facilitated to carry out quick assembly and disassembly.And it is preferred, in order to sufficiently expose the knife of blade 151
Head, punctures conehead 11 and is formed with sunk structure 112 perpendicular to the both sides of the edge of a knife 111, and sunk structure 112 can be more effective
The cutter head of blade 151 is sufficiently exposed and is cut.
The present embodiment puncture outfit, by setting back-up ring and annular air-pocket on puncture cannula, inserts puncture outfit during operation
The cutting part of patient so that annular air-pocket is fully-inserted into the human body, then, by the second connecting tube to being filled in annular air-pocket
Gas or water filling so that annular air-pocket inflating clip in vivo, and passes through to slide the back-up ring on human body so that back-up ring abuts in patient's
Back-up ring is locked on epitheca on skin and by lock, under the mating reaction of annular air-pocket and back-up ring so that puncture outfit jail
The fixation leaned on reduces the possibility for occurring sliding on a patient body, meanwhile, annular air-pocket again can effectively by patient's body
On otch block, it is to avoid the phenomenon that leaks air occurs, reduce occur slipping and gas leakage phenomenon；In addition, by even
Connect and (the first back-moving spring is set between cylinder and block, can realize that connecting cylinder is moved back and forth on base, when the puncture when puncturing
When conehead is subject to the resistance of tissue, puncturing conehead will promote connecting cylinder to be close to the movement of block direction, so that stab knife
Blade expose from the edge of a knife, the cutter head of blade exposes from the edge of a knife and will cut tissue so that puncture can smoothly enter
OK, and after the broken tissue of cutting, in the presence of (the first back-moving spring, connecting cylinder will reset rapidly so that the knife of blade
Head is quickly punctured conehead and shelters from again, the situation hair for accidentally injuring human internal organs occurs so as to avoid cutter head and expose all the time
It is raw, also, also the operation precision to medical personnel reduces requirement, and realization facilitates medical personnel to use puncture outfit, and raising is worn
Pierce the reliability of device.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
Modified with to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
