Technical field
The utility model is related to a kind of percutaneous puncture skin of radial development under medical treatment device, more particularly to a kind of visual scope
Skin draws drag hook.
Background technology
Hospital to patient implement body surface operation when, it is necessary to which integumentary musculature is cut after, surgical wound is entered with hook for surgery operation
Row drawing, fully to expose the visual field for being appropriate for operation, is easy to doctor to be performed the operation.The development of current head neck operation becomes
Gesture is gradually developed to Minimally Invasive Surgery.During visual endoscopic endoluminal surgery, because operating process is indirect operation, neck
The problem of portion's institutional framework is complicated, has the problem of endoluminal operational site operation is limited, now generally requires to draw using auxiliary
The help of hook, current existing steel wire puncturing operation drag hook has that single function, poor operability, practicality be not good enough,
Therefore in surgical procedure, the structure shortcoming of drag hook can influence operation progress, add the labor intensity of medical personnel, easily produce
Raw potential safety hazard, or even occur malpractice.Meanwhile, existing drag hook is mainly soft in visual endoscopic surgery region by pulling
Tissue enables operation key position to expose, but current drag hook is also it will be apparent that essentially consisting in drag hook the problem of exist
Material is softer, and not enough, drawing intraluminal tissue is laborious, while current puncture drag hook is only capable of carrying out intracavitary in one direction for hardness
Draw tissue, the operation technique limited space not only built is big, and drag hook stress surface is small, and the operation long-time of small otch is energetically
Cutting for degree draws local skin otch to cause the relaxation of skin incision, causes the out-of-flatness that postoperative skin otch is aligned to influence
The healing of wound, causes scar after the operation hyperplasia.
The content of the invention
The purpose of this utility model is that solving current hook for surgery operation can only draw in one direction of drag hook, the operation of structure
Operating space is limited greatly, and drag hook stress surface is small, and local pressure is big, and there is provided a kind of visual interior for the problem of influenceing post-operative recovery
The percutaneous puncture skin traction drag hook of radial development under mirror, in all formation face supports of drag hook ring, builds operation technique space fully,
It is small to injury of human and traction stress surface is big.
The utility model solves the technical scheme that its technical problem used：The warp of radial development under a kind of visual scope
Skin puncture skin traction drag hook, it is characterised in that：Including inside and outside nested central core bar and sleeve, central core bar front end is from sleeve
Front end is stretched out and is provided with the addendum cone for puncturing skin, if being uniformly arranged between addendum cone rear end and barrel forward end around center core bar
The gear ring that correspondence coordinates with arc-shaped tooth on arc-shaped tooth, central core bar shaft, tooth are set on the inside of dry abduction group valve, abduction group valve
The front side that rear end face is located at barrel forward end face is enclosed, sleeve rear end is stretched out as rotation drive end in the central core bar rear end.This dress
The addendum cone put is used to puncture skin, punctures after skin, the hand-held outer barrel of operating personnel, and the central core bar of driving is rotated, and central core bar leads to
Gear ring driving abduction group lobe swing is crossed outwards to deploy, hook on the inside of the skin, abduction group valve be uniformly arranged on ring week it is multiple, can
To provide multidirectional support, operation technique space is formed, after the completion of operation, central core bar, which is rotated backward, receives abduction group valve
Return, the present apparatus can be taken out from skin.Present apparatus shaft is rigidly good, compared to soft drag hook, is easily controlled during operation, and
Rapid operation.Present apparatus abduction group valve omnirange is outwards deployed, compared to unidirectional drag hook, without controlling drag hook direction, reduces
Local skin stress, is conducive to post-operative recovery；The operation technique space of formation fully, advantageously reduces operating difficulty, shortens hand
The art time.
Preferably, addendum cone rear end external diameter is consistent with sleeve outer diameter.When puncturing into skin, addendum cone rear end and sleeve
External diameter is consistent, and addendum cone has guide effect to the sleeve of rear side, it is ensured that is smoothly punctured and is entered skin；During taking-up, also ensure
It can smoothly take out, cross hook without local external diameter and draw skin to cause damage.
Preferably, the barrel forward end face is correspondingly arranged swinging axle prominent forward, the abduction group with abduction group valve
Lobe swing is set on swinging axle.
Preferably, the swinging axle front end is resisted against the rear surface of addendum cone.Barrel forward end formation is positioned, it is to avoid sliding
It is dynamic.
Preferably, the gear ring is close to setting on rear side of addendum cone.
Preferably, the rear end of the central core bar is connected with handle runner, handle runner external diameter is more than sleeve diameter.Hand
Handle runner not only drives central core bar to drive abduction group lobe swing, and forms spacing to sleeve rear end, it is to avoid slide.
Preferably, the handle runner and central core bar rear end are using threaded connection.
Preferably, positioned at the inner side of addendum cone rear end outer contour during the abduction group lobe swing withdrawal.
Preferably, the abduction group valve surface turning point uses round-corner transition.
The utility model sets the abduction group valve of swingable expansion around central core bar, and a step builds the operation behaviour under skin
Make space, and operation technique space supports for omnirange, reduces local skin stress, more conducively post-operative recovery, operation technique is empty
Between build more convenient, improve procedure efficiency, save operating time.
