Abstract
Double fork laminectomy retractors belong to the field of medical instrument technology, it is therefore intended that propose a kind of double fork laminectomy retractors, solve the problems, such as of the existing technology to be affiliated to not firm and be easy to cause fracture of transverse process.Double fork laminectomy retractors of the utility model include: L shape drag hook main body, and the L shape drag hook main body is slab construction；The arc bent plate of one end of L shape drag hook main body is set, and the transverse slat of the horizontal plane where the intrados towards the transverse slat of the L shape drag hook main body of the arc bent plate, the arc bent plate and L shape drag hook main body is staggered with respect to the riser of L shape drag hook main body；And two tips of L shape drag hook main body the other end are set, two tips are symmetrical arranged, the side arc-shaped transition that two tips are connected.Two tips of the utility model, constitute double fork structures, and double forks can be straddled transverse process root by when use can appear visual area well, and using being more easier, required strength is smaller, not will cause fracture of transverse process.
Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of double fork laminectomy retractors.
Background technique
Backbone cone fracture is the common disease of spinal surgery, seriously affects normal work, the living and studying of patient, is such as located
It is improper to manage, and often leaves serious complication, causes no small pain to patient.
Currently, the ophthalmic surgical treatment of backbone patient is fixed as clinical more use with the nail-stick system of Via Posterior Spinal Approach,
It needs that accurately pedicle nail is screwed into centrum in operation, because soft tissue is abundant on rear side of centrum, and as people are to minimally invasive skill
The pursuit of art, it is desirable that notch is smaller and smaller, thus needs to retract soft tissue during being screwed into pedicle nail, to expose
Tissue, otherwise can because exposure is unclear cause the location misalignment of pedicle nail to notch soft tissue caused by it is serious strand frustrate damage, production
The raw postoperative failure syndrome of backbone.
In the prior art, laminectomy retractor is generallyd use to appear visual area, and current laminectomy retractor end is a tip, is made
Tip is affiliated on transverse process point by the used time, then pulls open soft tissue.This drag hook is difficult to be affiliated to when transverse process is longer
It goes, it is not firm to be affiliated to, and it is abundant additionally, due to the muscle of lumbar vertebrae, it needs biggish strength that can just pull open, is affiliated to and is easy on transverse process
Fracture of transverse process is caused, brings pain to patient.
Utility model content
The purpose of this utility model is that propose a kind of double fork laminectomy retractors, solve it is of the existing technology be affiliated to it is not firm
And the problem of be easy to causeing fracture of transverse process.
To achieve the above object, double fork laminectomy retractors of the utility model include:
L shape drag hook main body, the L shape drag hook main body are slab construction；
The arc bent plate of one end of L shape drag hook main body is set, and the intrados of the arc bent plate is drawn towards the L shape
Riser of the transverse slat of horizontal plane where the transverse slat of hook main body, the arc bent plate and L shape drag hook main body with respect to L shape drag hook main body
It is staggered；
And two tips of L shape drag hook main body the other end are set, two tips are symmetrical arranged, two tips
The side arc-shaped transition being connected.
The tip is bent downwardly with respect to transverse slat, and bending angle value range is 0-30 °.
The arc bent plate, L shape drag hook main body and tip are an integral structure, and thickness is equal.
The width of the arc bent plate is less than the width of L shape drag hook main body.
It is arc-shaped transition at the L shape drag hook main bent part.
The utility model has the following beneficial effects: double fork laminectomy retractors of the utility model are by a L shaped plate as drag hook
Main body, one end, which is provided with arc bent plate, to be realized and is affiliated to transverse process, and the other end is symmetrical arranged there are two tip, constitutes double pitch
Structure, double forks can be straddled transverse process root when use can appear visual area well, using being more easier, required strength
It is smaller, it not will cause fracture of transverse process.
Detailed description of the invention
Fig. 1 is double fork laminectomy retractor overall structure diagrams of the utility model；
Fig. 2 is double fork laminectomy retractor structural front views of the utility model；
Fig. 3 is double fork laminectomy retractor the structure left view of the utility model；
Fig. 4 is double fork laminectomy retractor prong structure schematic diagrames of the utility model；
Wherein: 1, L shape laminectomy retractor, 101, transverse slat, 102, riser, 2, arc bent plate, 3, tip.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Referring to attached drawing 1- attached drawing 4, double fork laminectomy retractors of the utility model include:
L shape drag hook main body 1, the L shape drag hook main body 1 are slab construction；
The arc bent plate 2 of 1 one ends of L shape drag hook main body is set, and the intrados of the arc bent plate 2 is towards the L
The transverse slat 101 of horizontal plane where the transverse slat 101 of shape drag hook main body 1, the arc bent plate 2 and L shape drag hook main body 1 is with respect to L shape
The riser 102 of drag hook main body 1 is staggered；
And two tips 3 of described 1 the other end of L shape drag hook main body are set, form double fork structures, two tips 3
It is symmetrical arranged, the side arc-shaped transition that two tips 3 are connected.It avoids damaging across at transverse process root.
The opposite transverse slat 101 of the tip 3 is bent downwardly, and bending angle value range is 0-30 °.
The arc bent plate 2, L shape drag hook main body 1 and tip 3 are an integral structure, and thickness is equal.Guarantee integrally-built
Rigidity.
The width of the arc bent plate 2 is less than the width of L shape drag hook main body 1.
1 bending part of L shape drag hook main body is arc-shaped transition, avoids when in use causing human body due to accidentally operating
Secondary injury.
The radian of the arc bent plate 2, arc length, the size of L shape drag hook main body 1 and the size of tip 3 can be according to realities
It is chosen on border.
When the utility model is used, double forks straddle transverse process root, can be very good to appear visual area, using more holding
Easily, compared with existing laminectomy retractor, required strength is smaller, not will cause fracture of transverse process.
