Technical field
The utility model is related to technical field of medical instruments, more particularly to a kind of multipurpose vertebra way of escape retractor.
Background technology
Posterior spinal operation is the important approaches for treating the spinal diseases such as spine fracture, spondylolishesis, wherein joint
Prominent, transverse process appears for positioning pedicle of vertebral arch that to enter nail point most important.For the ease of fully sudden and violent leakage surgical field of view, generally require to use
Appeared to multipurpose vertebra way of escape retractor.Traditional multipurpose vertebra way of escape retractor, can only due to only one of which tooth
Stop the soft tissue on the outside of the up or down incisura of pedicle of vertebral arch, it is impossible to completely appear into nail point, often appear transverse process side, and it is another
Side soft tissue is still covered, if placing drag hook simultaneously in transverse process both sides, otch accommodates difficulty, and cooperation is difficult to coordinate, because
This occurs in that the retractor with bidentate structure.
As Chinese patent literature CN202619730U discloses a kind of bidentate vertebral plate drawing hook, it is arranged in the bottom of pull end
There are two briar tooths, two briar tooths are arranged near both sides, and the body width of briar tooth is basically identical, and the prominent point of transverse process, articular process
Part is curved, and during actual operation, the bidentate vertebral plate drawing hook is difficult to match the prominent sharp structure of transverse process and articular process,
And then needing the more time adjustment installation site of consuming to keep stablizing so as to entirely pull hook when mounted, this not only delays
Operation progress, while the briar tooth that is in course of adjustment causes secondary injury to the soft tissue of transverse process, articular process position, have impact on operation
Quality.
Utility model content
For this purpose, the technical problems to be solved in the utility model is the above-mentioned disadvantage for overcoming existing vertebra way of escape retractor to exist
End, and then provide and a kind of new be conveniently adjusted installation site, save the retractor set-up time and effectively reduce to transverse process, close
The soft tissue of the prominent position of section causes the multipurpose vertebra way of escape retractor of secondary injury.
For achieving the above object, the utility model is employed the following technical solutions：
A kind of multipurpose vertebra way of escape retractor, it includes front block unit and pulling portion, and the tail end of the pulling portion is provided with
The hook portion being connected with pull rope, the lower end of the front block unit is provided with two spaced briar tooths, two briar tooths it is interior
The V-shaped opening in side, is provided with the cavity being recessed along the thickness direction of the front block unit between the root of two briar tooths,
The cavity is suitable to transverse process or the prominent pinnacle of articular process enters.
Preferably, the cavity is the through hole of blind hole type cavity or open type.
Preferably, longitudinal tangent plane of the briar tooth root is trapezoidal, and the width and thickness of the briar tooth is from root to tip
Gradually taper up, two sides of the briar tooth are domatic in 30-40 degree.
Preferably, the root inner side spacing of two briar tooths is 5-10 millimeters.
Preferably, the briar tooth and the front block unit are integral type structure, or the briar tooth is weldingly fixed on the front
The lower end in portion.
Preferably, the front block unit is molded with the pulling portion by one piece of 90 degree of steel plate bending
The beneficial effects of the utility model：
Multipurpose vertebra way of escape retractor of the present utility model in the lower end of front block unit by arranging medial surface in V arrangements
Briar tooth and the cavity being recessed along front block unit thickness direction item, the structure is solid from the prominent point and both sides screens of transverse process or articular process
It is fixed, with preferable steadiness, dome shape projection or ellipticity are may be designed in the cavity overall structure of cavity, in order to transverse process
Or the prominent nose part of articular process heads into and voluntarily adjusts the position of stress point and accepts direction, and two briar tooths are then from both sides card
Position, limits the double swerve of front apron, and guides prominent point voluntarily to push in cavity and play a part of three-point fix；Installed
Journey can be positioned voluntarily, therefore, it is possible to save more adjustment time, and be mitigated to transverse process or joint thumping point position soft tissue
Secondary injury.
Description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below in conjunction with the accompanying drawings, the utility model is made
Further details of explanation, wherein：
