Abstract
The utility model belongs to the technical field of medical instruments, and particularly relates to a novel lumber interertebral disc excision trephine. The novel lumber interertebral disc excision trephine comprises a trephine body and a handle, wherein the trephine body is perpendicular to the handle to form a T shape. The trephine body is of a cylinder, trephine teeth are arranged at the top end of the trephine body, a through hole is formed in the middle of the handle, the trephine body is divided into a thick part and a thin part, the thick part is on the part, 1 cm to the trephine teeth end, of the trephine body, the thin part is communicated with the through hole in the handle, and the diameter of the thin part is the same as the diameter of the through hole. According to the novel lumber interertebral disc excision trephine, the structure is simple, use is convenient, due to the design that the trephine body is thickened from the position which is 1 cm to the trephine teeth and reduced in diameter from the position which is 1 cm to the trephine teeth, the advancing resistance of the trephine is increased, the depth that the trephine enters a body is easy to control, over damage to nerve roots and over damaged to blood vessels are avoided, bleeding is reduced, and surgical risks are effectively reduced.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of novel lumbar discectomy trepan.
Background technology
Usually when the treatment intervertebral disc prolapse, under the situation of prolapse of intervertebral disc, intervertebral foramina is very narrow usually, and affected nerve root from the beginning side is sent, and is held by fibrous tissue or bone vertebral body usually.In order to make the service aisle spinal column chamber of arriving safe and sound, use the trepan rotation to remove the sclerotin of little joint far-end hypertrophy and the part expansion intervertebral foramina of part upper joint projection, make the service aisle of spinal endoscopes arrive the spinal column chamber, use operating theater instruments to extract the nucleus pulposus that hernia goes out, reach the purpose for the treatment of intervertebral disc prolapse.At present, trepan wayward degree of depth in operation process commonly used, and stimulation or injured nerve, blood vessel have easily increased the risk of operation.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and effectively neuroprotective root and blood vessel reduce hemorrhage novel lumbar discectomy trepan.
This utility model is that the technical scheme that its technical problem of solution adopts is: novel lumbar discectomy trepan, comprise saw body and the handle of the vertical T of one-tenth shape mutually, the saw body is cylinder, the top is provided with sawtooth, through hole is arranged in the middle of the described handle, described saw body is divided into thick portion and thin portion, is thick portion for 1 centimetre near sawtooth one end on the described saw body, described thin portion communicate with through hole on the handle and diameter identical.
The length of described trepan from the sawtooth to the through hole is 15 centimetres.
The thick portion of described saw body diameter is 6 millimeters, and the thin portion of described saw body diameter is 4 millimeters.
Compared with prior art, the utlity model has following beneficial effect: this utility model is simple in structure, easy to use, the saw body begins to thicken the design that diameter diminishes from distance sawtooth 1 centimeters and has increased the resistance that trepan advances, be easy to control trepan and enter the interior degree of depth of body, avoid excessive damage nerve root and blood vessel, reduce hemorrhagely, effectively reduce operation risk.
