Description

The orthopedic combined utensil of scheuermann kyphosis deformity vertebra osteotomy

This utility model is to belong to the medical apparatus and instruments that Orthopeadic Surgery uses.

In recent ten years, spinal operation is orthopedic successively carries out in China part hospital.When using the operation of normal aggregates osteotomy apparatus, can push dural sac, Spinal Cord causes patient's paralysis easily, brings misery to the patient.

The purpose of this utility model proposes the orthopedic combined utensil of a kind of scheuermann kyphosis deformity vertebra osteotomy, through posterior approach operative treatment scheuermann kyphosis deformity, around the capable vertebra bone-culting operation of dural sac, can not damage dural sac, and the patient is got well early.

This utility model is by vertebral body detacher 1; the vertical deep cutter 2 of vertebral body trailing edge; vertebral body located lateral twolip osteotome 3; the horizontal deep cutter 4 of vertebral body; cutter 5 is pressed in the embedding of vertebral body trailing edge plane; cutter 6 is pressed in the embedding of vertebral body osteotomy wound surface bald head; vertebral body skid plate 7; spinal dura mater protection plate hook 8; spinous process card punch 9 is formed; as Fig. 1; 2; 3; 4; 5; 6; 7; 8; shown in 9: it is characterized in that: by vertebral body detacher 1; the vertical deep cutter 2 of vertebral body trailing edge; vertebral body located lateral double-edge chisel 3; the horizontal deep cutter 4 of vertebral body; cutter 5 is pressed in the embedding of vertebral body trailing edge plane; cutter 6 is pressed in the embedding of vertebral body osteotomy wound surface bald head; vertebral body skid plate 7; spinal dura mater protection plate hook 8; spinous process card punch 9 is formed; wherein vertebral body detacher 1 is the awl rib bodily form; leading section is curved; the vertical deep cutter 2 of vertebral body trailing edge is awl rib bodily forms; anterior curved; front end is vertical scalpriform; the horizontal deep twolip osteotome 3 of vertebral body is awl rib bodily forms; the front end twolip; between two twolips spacing is arranged; one side is vertical; opposite side is curved; the horizontal deep cutter 4 of vertebral body is awl rib bodily forms; front end one side is vertical; opposite side is curved; it is awl rib bodily forms that cutter 5 is pressed in the embedding of vertebral body trailing edge plane; front top is the plane; one side is vertical; one side is curved; it is awl rib bodily forms that cutter 6 is pressed in the embedding of vertebral body osteotomy wound surface bald head; front top is triangular in shape blunt nosed; one side is vertical, and a side is curved, and vertebral body skid plate 7 is slab; leading section is curved; the top is crown shape, and hard ridge mould protection plate hook is a slab, and front end is curved; the top oppositely bends; spinous process card punch 9 is handle shape, and front end is sharp-pointed, and the rear end is horizontal handle.

This utility model is made up of three part utensils, and vertebral body appears: be made of vertebral body detacher 1, vertebral body skid plate 7, spinal dura mater protection plate hook 8; Vertebral body osteotomy: press cutter 5, the embedding of vertebral body cross section wound surface bald head to press cutter 6 to constitute by the vertical deep cutter 2 of vertebral body trailing edge, the deep twolip osteotome 3 of vertebral body located lateral, the horizontal deep cutter 4 of vertebral body, the embedding of vertebral body trailing edge plane; Spinal fixation: constitute by the spinous process card punch.Its concrete operations are as follows: 1, vertebral body appears: 1., the side appears, vertebral body side detacher, excision transverse process and as indication point, vertically along the vertebral body middle part forward subperiosteum peel off and reach the vertebral body front side, peel off with the method offside.2., the rear appears, with common meninx dissector with dural sac the place ahead and the back is vertical rein between the crack strip off, use dural sac protection plate hook, with dural sac gently pull to a side appear a pleurocentrum trailing edge, with the method contralateral exposure.

2, vertebral body osteotomy: vertebral body side skid plate, front end are stuck in vertebral body side the place ahead, sled is pressed soft tissue laterally, appears the vertebral body side.Spinal dura mater protection plate hook is led spinal dura mater to offside gently by this rear flank edge, appears the vertebral body rear.Use vertebral body osteotomy cutter, the recessed subtend dural sac protection of arc plate hook, earlier with osteotomy locate deep cutter vertebral body trailing edge middle part by after cut forward dark 1 centimetre.Decorporate location cutter, vertebral body is walked crosswise deep cutter, by the vertebral body side along location cutter incisura forward the wedge shape incision reach vertebral body 3/4 deeply.With method offside osteotomy.The vertical deep cutter of vertebral body trailing edge, chisel edge along the vertebral body y direction, by after vertically cut 3/4 forward, cut off the vertical cortical bone of vertebral body trailing edge, and sled is dialled and is downcut vertebral body sphenoid piece laterally.With method offside osteotomy.Vertebral body trailing edge osteotomy plane cutter by the side visit reach dural sac the place ahead, vertically the residual bone piece of vertebral body trailing edge osteotomy is pressed in embedding forward.Use the bareheaded embedding of vertebral body osteotomy wound surface to press cutter at last, respectively at vertebral body osteotomy wound surface, smooth osteotomy wound surface is squeezed in embedding, and vertebral body side the place ahead and the place ahead cortical bone are stopped blooding, also vertically thrust forward in extruding.

3, spinal fixation: osteotomy finishes, and scheuermann kyphosis is rectified and put in order, the osteotomy wound surface closes up, and needs row vertebral plate spinous process to fix, and uses the spinous process card punch.The 2-3 individual not spinous process basilar part of osteotomy spinal column in two ends laterally punches about the osteotomy vertebra, so that lay the interplantation metal fixture.

This utility model has following advantage compared with prior art:

Scheuermann kyphosis deformity surgical orthopaedic special combination utensil, by vertebral body appear, vertebral body osteotomy, vertebral plate spinous process fix three parts and form.Its performance is single-minded, easy to operate, finishes the vertebral body osteotomy around dural sac, and apparatus does not constitute the extruding of spinal cord and damage.Finish bone-culting operation in principle at the protection spinal cord.Osteotomy is complete, and deformity of spine is rectified and put in order, the interplantation metal object is fixed, the punching of vertebral plate spinous process, sees hard, the common spinous process card punch of ankylosing spondylitis kyphosis deformity patient sclerotin and can not finish punching.Make the spinous process card punch according to the wild dark characteristics of art, punching is used to wear passs steel wire and interplantation fixture.This utensil is easy to use, and is multiple functional, and the protection spinal cord is fixed, and the patient is got well very soon.
