The utility model discloses among the doctor's foraminiferous mirror minimal access surgery process, especially, pierce through lumbar vertebrae facet joint shoulder and reach the intraductal protruding nucleus pulposus in-process of vertebra, the effort that utilizes needle end inclined plane and lumbar vertebrae on the reaction force mechanism of articular process sclerotin can carry out the fine setting of puncture direction, better supplementary doctor looks for the target point position of pathological change position and puncture, reduce the puncture among the operation process not in place, the wound that the puncture leads to repeatedly, its institutional advancement is simple, reasonable, easily realize, the doctor can choose the direction needle after the improvement for use according to pathological change angle and position, the defect of intervertebral foraminiferous mirror operation apparatus direction needle has been filled, therefore the utility model discloses be fit for popularizing and applying.
Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a foraminiferous mirror minimal access surgery is with direction needle that punches.
Background
The transforaminal endoscope is a tube provided with a light, and enters an intervertebral foramen from the side or the lateral back of the body of a patient (can be flat and can be inclined), and the operation is carried out in a safe working triangular area. The operation is performed outside the intervertebral disc fibrous ring, and the protruded nucleus pulposus, nerve roots, the dural sac and the hyperplastic bone tissues can be clearly seen under the direct vision of an endoscope. Then, various grasping forceps are used for removing the protruded tissues, bone is removed under a mirror, and the damaged fibrous ring is repaired by the radio frequency electrode. The operation wound is small: the skin incision was only 7mm, as one soybean grain size, bleeding was less than 20ml, and only 1 needle was sutured after surgery. Is a minimally invasive therapy for treating the protrusion of the intervertebral disc with the least trauma and the best effect on patients in the similar operations.
The doctor is at the operation in-process, utilize the instrument to puncture to cervical vertebra intervertebral disc back, utilize the work sleeve pipe as the passageway, then put into operation tools such as radio frequency through this passageway, at first need safe, accurate puncture to the pathological change position in this operation process, the accuracy of target point puncture location is first and foremost, the location is inaccurate can influence treatment, the syringe needle end structure of current guide needle that punches all is three arriss and blunt head, the shortcoming is that the doctor is difficult better the fine setting operation of carrying out the puncture direction at the location in-process of puncture lumbar vertebrae facet joint department shoulder, can not satisfy the location demand.
Therefore, the above problems should be solved in time by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to foretell problem, provide a foraminiferous mirror minimal access surgery is with institutional advancement of punching guide needle, the guide needle after the improvement can finely tune in puncture lumbar vertebrae facet joint shoulder angle, and better supplementary doctor looks for the pathological change position, and its institutional advancement is simple, reasonable, easily realize, and the doctor can choose the guide needle after the improvement for use according to pathological change angle and position, has filled the defect of foraminiferous mirror surgical instruments guide needle.
In order to achieve the above purpose, the present invention is realized by the following technical solutions: the utility model provides an intervertebral foramen mirror minimal access surgery is with direction needle that punches, the structure includes that the metal punches the direction needle body, its characterized in that: one end of the metal punching guide needle body is arranged to be a bevel plane, and the other end of the metal punching guide needle body is provided with a guide needle fixer which is fixedly connected with the other end of the metal punching guide needle body in a threaded manner.
Preferably, the diameter of the metal punching guide needle body is 1.8mm, the length of the metal punching guide needle body is 250mm, and the angle of the inclined plane α of the needle point of the inclined plane is 45-60 degrees.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the utility model discloses among the doctor's foraminiferous mirror minimal access surgery process, especially, pierce through lumbar vertebrae facet joint shoulder and reach the intraductal protruding nucleus pulposus in-process of vertebra, the effort that utilizes needle end inclined plane and lumbar vertebrae on the reaction force mechanism of articular process sclerotin can carry out the fine setting of puncture direction, better supplementary doctor looks for the target point position of pathological change position and puncture, reduce the puncture among the operation process not in place, the wound that the puncture leads to repeatedly, its institutional advancement is simple, reasonable, easily realize, the doctor can choose the direction needle after the improvement for use according to pathological change angle and position, the defect of intervertebral foraminiferous mirror operation apparatus direction needle has been filled, therefore the utility model discloses be fit for popularizing and applying.
