Abstract
For a trepan for Thoracolumbar disk anterior decompression, be made up of trepan, handle and locating rod, trepan is hollow circular tube, and its one end is connected with disk, and the other end is provided with sawtooth; The periphery of disk is provided with screwed hole; One end of locating rod is tapered, and tapering is provided with screw thread; Handle is connected by screwed hole with the disk of trepan one end; The other end of locating rod is provided with scale.This utility model adopts trepan to remove the bone block of canalis spinalis front pressuring nerve, and than osteotome handling safety, and easy and simple to handle, technology is easy to grasp, and shortens operating time; In addition, because the tail end of locating rod is provided with scale, conveniently can observe that trepan screws in the degree of depth in bone, prevent from trepan from entering taking an advanced study into the damage of surrounding tissue.This utility model structure is simple, manufactures easy, with low cost, and this apparatus also has dismounting and the feature of assembling, is convenient for carrying, in actual applications convenient operation, is applicable to the traumatology department, orthopaedics and spinal surgery.
Description
Technical field
This utility model relates to orthopaedics or field of spinal surgery, relates to thoracolumbar burst fractures Spinal Cord front pressurized, needs row anterior-lateral decompression field of surgery, is a kind of trepan for Thoracolumbar disk anterior decompression specifically.
Background technology
In prior art, thoracolumbar burst fractures Spinal Cord front pressurized, the patient with operation of anterior-lateral decompression need be carried out, in operation process, what adopt is Electric grinding drill or osteotome technology, and the local tissue damage of this technology to patient is heavier, and operation easier is large, operating time is long, is therefore difficult to application.
Utility model content
In sum, technical problem underlying to be solved in the utility model is to provide a kind of trepan for Thoracolumbar disk anterior decompression.
Technical problem of the present utility model adopts following technical proposals to solve:
For a trepan for Thoracolumbar disk anterior decompression, be made up of trepan, handle and locating rod, trepan is hollow circular tube, and its one end is connected with disk, and the other end is provided with sawtooth; The periphery of disk is provided with screwed hole; One end of locating rod is tapered, and tapering is provided with screw thread; Handle is connected by screwed hole with the disk of trepan one end; The other end of locating rod is provided with scale.
This utility model is applicable to thoracolumbar burst fractures Spinal Cord front pressurized, or traumatic spinal anterior approach Progressive symmetric erythrokeratodermia increases the weight of, the sclerotin of generation vertebral body center pillar is convex gradually needs row anterior-lateral decompression to perform the operation to canalis spinalis compressing spinal cord, also be applicable to spinal anterior approach and need row Anterior release, row kyphosis deformity is corrected.
Advantage of the present utility model and beneficial effect:
1, this utility model is by simple machinery, instead of the artificial mode of knocking and beating by hand in the past, patient's physical demands can be alleviated, breast waist section effective canalis spinalis front decompression treatment can be reached again, be conducive to the recovery of function of nervous system, alleviate operation wound, coordinate medicine and rehabilitation training simultaneously, can therapeutic effect be significantly improved.
2, this utility model adopts trepan to remove the bone block of canalis spinalis front pressuring nerve, and than osteotome handling safety, and easy and simple to handle, technology is easy to grasp, and shortens operating time.
3, the locating rod tip in this utility model is tapered, and is provided with screw thread, can insert in trepan center, and its tail end has scale, for location, conveniently can observe that trepan screws in the degree of depth in bone.
4, this utility model structure is simple, manufactures easy, with low cost, and this apparatus also has dismounting and the feature of assembling, is convenient for carrying, in actual applications convenient operation, is applicable to the traumatology department, orthopaedics and spinal surgery.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1,2,3, 4, a kind of trepan for Thoracolumbar disk anterior decompression, is made up of trepan 1, handle 2 and locating rod 3, and trepan 1 is hollow circular tube, and its one end is connected with disk 101, and the other end is provided with sawtooth 103; The periphery of disk 101 is provided with screwed hole 102; One end of locating rod 3 is tapered, and tapering is provided with screw thread; Handle 2 is connected by screwed hole 102 with the disk 101 of trepan 1 one end; The other end of locating rod 3 is provided with scale.
Embodiment
Adopt general anesthesia, left lateral position, routine disinfection paving is single, gets the large kidney otch in right side, cuts skin subcutaneous, as the decompression of row lumbar vertebra front, need row breast, rib to excise.
Appear the front, vertebral body side of compressing spinal cord, waist traversing arteries and veins is cut off in ligation.Remove with laminectomy rongeur and hinder vertebra pedicle of vertebral arch, manifesting myeloid tissue's pressurized position, is generally intervertebral disc, vertebral body trailing edge and the posterior longitudinal ligament tissue given prominence to from front to back.
Myeloid tissue's pressurized position is protected with nerve dissector; by the trepan 1 that front for the Thoracolumbar disk combined road subtracts; perpendicular alignmnet urging tissue; first screw in locating rod 3 about 40 mm; again the trepan 1 combining handle 2 is inserted in locating rod 3; by handle 2 slow circumvolve trepan 1, make to enter canalis spinalis and cause the sclerotin of spinal cord front pressurized to remove.
Locating rod 3 tail end has scale, the degree of depth that trepan 1 can be pointed out to enter, and prevents trepan 1 from entering deeply, causes the damage of surrounding tissue.
When discovery locating rod 3 during turn, just represents that the degree of depth screwed in is just right, after completing the excision to the sclerotin entering canalis spinalis, can take off trepan 1 together with trepan 1.
To carry out second or the 3rd operation of trepan by similar approach.
Generally to urging tissue application upper, middle and lower three trepan, the excision of front, side sclerotin to the compressing sclerotin of myeloid tissue just can be completed.
