Notch traction size can be changed by replacing button hole position；This retractor is additionally provided with elevating lever, winding box, traction steel wire and upper traction and draws
Hook, upper traction drag hook are used for the tiltedly upper traction of arcus costarum or pelvis notch.The traction of horizontal drag hook adjusts part structure in the retractor
Make simply, and adjust and not very facilitate, stability in use is not good enough, which is not suitable for operation on neck yet.
CN203328746U discloses a kind of operative incision and retracts fixator, it is by snap ring, elastic pipeline body in lower elasticity
Connected and composed in succession with elastic outer snap ring, snap ring has two movable ends in elasticity, and a movable end is provided with some button holes, another activity
End sets snap-fastener, and snap ring size in different button hole energy regulation elasticities is inserted into by snap-fastener, and big ditty is retracted so as to fulfill operative incision
Section.The Application of device has much limitation, is not suitable for cervical operation cut and retracts.
CN201591583U discloses a kind of surgical incision retractor, which has a plastically deformable annulus, circle
Symmetrical drawing has four positioning to lead position band on ring, and deformation annulus is used to be fixed in operative incision, and leading change by traction belt becomes
Shape toroidal is to change operative incision shape.The retractor function is limited to very much, and the traction for being also not suitable for cervical operation cut is determined
Position.
Notch is retracted generally by manually pulling in operation on neck operation at present, makes operation have to increase operating personnel, people
Also there is the problems such as arbitrariness is also big, and stability is not good enough in work drawing.
Still lack use and retractor for neck surgery product easy to adjust in the prior art, also have no relevant report.
The content of the invention
The invention solves the prior art lack using and retractor for neck surgery easy to adjust, cause it is such operation by
People's notch that works retracts, and increases operating theatre staff, and because random bad with stability caused by manually retracting the problems such as,
There is provided for this present invention a kind of retractor for neck surgery, use of this operation retractor with easy to adjust, operative incision retract and
Positioning stablity, saves and manually retracts operating personnel.
To solve the above problems, its special character of the technical solution adopted by the present invention is provided with an endless glide, the cunning
