Abstract
The utility model provides a bone chisel for a spine operation, which comprises a handle, a chisel rod, a chisel block and a chisel head. The end head of the chisel rod is the L-shaped chisel head, and the chisel head has no edge and is smooth and obtuse. The bone chisel overcomes the defect that at the operation for complex or about two-week fracture block recovery in the prior art, the operation for fracture block recovery is carried out through overly drawing spinal cord or cauda equina nerve in a vertebral canal to cause more serious damage to the spinal cord so as to lead to more serious paralysis. By using the bone chisel to execute spine operation, under the protection of nerve elevator, the bone chisel reaches the corpus vertebrae along the radians at the two sides of the vertebral canal; and because the chisel tip and the chisel rod form an angle of 90 degrees, excess drawing of the vertebral canal is not needed, the chisel tip can prop up a shifting bone block, and the shifting bone block can be recovered by light hammer blow which has little interference to the spinal cord or the cauda equina nerve. Compared with the prior art, the bone chisel for the spine operation has the advantages of convenient operation, safety and reliability, has little interference to the spinal cord or the cauda equina nerve, and effectively avoids iatrogenic damage.
Description
Technical field
This utility model provides a kind of spinal operation medical apparatus and instruments, is specifically a kind ofly to reset undesirablely for moving internal fixation device behind the bursting fracture of vertebral body bone piece, carries out spinal operation and a kind of novel operation apparatus of providing.
Background technology
No matter bone piece compressing spinal cord or cauda equina nerve have or not the nerve compression symptom behind the clinical bursting fracture of vertebral body, must operative treatment to remove the bone sexual oppression.Operation divides preceding road and two kinds of art formulas of the way of escape, and the generally capable vertebral plate decompression of posterior approach, LOCATION OF PEDICLE SCREW FIXATION system reset fixing, and bursting fracture can obtain satisfied resetting mostly.But the fracture for some about complicated or two weeks connects and moves sclerite after causing and can't reset because ligament injury is heavier or formed fiber, and spinal cord or cauda equina nerve compressing can not effectively be removed.Existing osteotome is a linear type, when carrying out complexity or the sclerite reattachment surgery about two weeks, needs spinal cord, horse hair in the excessive tractive canalis spinalis, just can carry out the operation of sclerite reattachment surgery.Canalis spinalis is by vertebral body, and vertebral arch, vertebral plate constitute an oval tube chamber jointly, and by spinal cord, horse hair and cerebrospinal fluid are full of in the tube chamber.And spinal cord, horse hair belong to the central nervous system, and slight compressing or tractive just can cause irreversible damage, cause panplegia or paresis.Behind the bursting fracture of vertebral body, move the existing damage in various degree of spinal cord or cauda equina nerve behind the bone piece,, cause paralysis to increase the weight of or paresis becomes panplegia if going excessive tractive this moment again will cause spinal cord injury to increase the weight of.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of bursting fracture of vertebral body bone block reset that is used for, and is convenient to operate, to spinal cord and less, the safe and reliable osteotome of cauda equina injury.
The technical solution of the utility model is: a kind of osteotome, comprise handle, cutter bar, cutter pier and cutter head, and the termination of cutter bar is L shaped cutter head, the no sword of cutter head is smooth, blunt rounded.
Cutter head described in the utility model is 90 degree with the cutter bar.
When implementing spinal operation; peel off under the son protection at nerve; osteotome of the present utility model arrives vertebral body along canalis spinalis both sides radian; because of chisel edge and cutter bar are 90 degree; do not need excessive tractive canalis spinalis; chisel edge can push up mutually with displacement bone piece, and slight hammering displacement bone piece can reset and spinal cord and cauda equina nerve are disturbed seldom.Compared with prior art, this utility model is convenient to operation, and is less, safe and reliable to spinal cord and cauda equina nerve interference, effectively avoided iatrogenic injury.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Among the figure, this utility model comprises cutter pier 1, handle 2, cutter bar 3 and cutter 4, cuts a hole one centimeter of bar 3 termination certainly and locates 90 degree pre-bendings, makes L shaped cutter 4, and cutter 4 a no sword are smooth, blunt rounded.
Claims (2)
1, a kind of osteotome comprises cutter pier (1), handle (2), cutter bar (3), and it is characterized in that: the termination of cutter bar (3) is a L shaped cutter head (4), and cutter head (4) no sword is smooth, blunt rounded.
2, osteotome according to claim 1 is characterized in that: cutter head (4) is 90 degree with cutter bar (3).
