Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a simple structure, anterior longitudinal ligament cutting are efficient, the operation risk reduces, the operation time shortens, and the operation success rate improves be arranged in anterior longitudinal ligament abscission of full vertebra monoblock art.
Background
It is well known that malignant spinal tumors are invasive and can erode surrounding bone and soft tissue, causing significant pain, pathological fractures, and neurological dysfunction. The current clinical treatment strategy for spinal tumors is surgical resection with adjuvant therapy. The total spine monobloc resection can effectively improve the overall survival rate and the tumor control rate of patients, becomes an effective mode for treating spinal tumors, and is gradually accepted and applied by extensive spinal surgeons. However, this is a technically demanding procedure requiring a great deal of experience and a thorough understanding of the local anatomy of the operator. In long-term clinical practice, the limitation of surgical instruments brings huge obstacles to the whole-block excision of the whole spine, and particularly, no special auxiliary tool is provided for the separation of the upper and lower anterior longitudinal ligaments adjacent to the diseased vertebra, thereby bringing huge difficulties and risks to the operation.
Disclosure of Invention
The utility model aims at solving the deficiencies of the prior art, providing a anterior longitudinal ligament disjunction instrument that is arranged in full vertebra monoblock excision that simple structure, anterior longitudinal ligament cut efficient, operation risk reduce, operation time shorten, the operation success rate improves.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an anterior longitudinal ligament breaks instrument in being used for whole excision of vertebra, includes handle, connecting rod and tool bit, its characterized in that the one end of connecting rod be connected with the handle, the connecting rod by near-end to the distal end taper down gradually and with tool bit body coupling connected with the handle, the tool bit side is equipped with the cutting edge, the one end and the connecting rod body coupling of tool bit, the other end of tool bit is the blunt form of crotch towards the cutting edge bending.
The connecting rod on be equipped with the scale groove, be equipped with the scale sign on the connecting rod of scale groove side, scale groove and scale sign establish with the tool bit on the connecting rod of cutting edge back homonymy, be convenient for master the tool bit and get into the degree of depth.
The handle on be equipped with bar recess or annular knurl recess, the increase grips frictional force, improves operator stability and accuracy.
The handle of the utility model is 14-15cm in length, the connecting rod is 11-13cm in length, and the tool bit is 2-4cm in length.
By adopting the above structure, the utility model, have simple structure, anterior longitudinal ligament cutting is efficient, the operation risk reduces, the operation time shortens, advantages such as operation success rate improves.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in the attached drawing, the instrument for separating and breaking the anterior longitudinal ligament in the total spine monoblock resection comprises a handle 1, a connecting rod 2 and a cutter head 3 and is characterized in that one end of the connecting rod 2 is connected with the handle 1, the connecting rod 2 becomes thinner gradually from a near end connected with the handle 1 to a far end and is integrally connected with the cutter head 3, a cutting edge 4 is arranged on the side surface of the cutter head 3, one end of the cutter head 3 is integrally connected with the connecting rod 2, and the other end of the cutter head 3 is bent towards the cutting edge 4 to form a blunt hook shape 5.
Further, connecting rod 2 on be equipped with scale groove 6, be equipped with the scale sign on the connecting rod 2 of scale groove 6 side, scale groove 6 and scale sign establish with tool bit 3 on the connecting rod 2 of 4 back homonymies of cutting edge, be convenient for master tool bit 3 and get into the degree of depth.
Further, handle 1 on be equipped with bar recess 7 or annular knurl recess, increase grip friction, improve operator stability and accuracy.
Further, the length of the handle 1 is 14-15cm, the length of the connecting rod 2 is 11-13cm, and the length of the cutter head 3 is 2-4 cm.
The utility model discloses a handle 1 adopts bar groove 7 or annular knurl recess, the purpose is to improve the frictional force that the art person gripped, length is about 14-15cm, be convenient for both hands to grip, do benefit to and improve accuracy and stability of operation, the dorsal scale sign of connecting rod 2 of design, and become thin gradually by the near-end and the distal end of handle 1 junction, be convenient for the distal end to pass through intervertebral disc region and leave certain operating space, dorsal scale sign length is about 11-13cm, length overlength or short can make the operation hard and reduce the accuracy, through long-term clinical experience it is moderate to ask for this length to do benefit to the operation, it gets into the degree of depth to be convenient for the art person to master, avoid getting into the risk that the important organizational structure in the front of centrum damages that leads to getting into deeply, the tool bit 3 of design, length is 2-4cm, tool bit 3 farthest end is crooked towards cutting edge 4 and is hook blunt form 5, can not only perceive the breakthrough sense of ligament before the operation, and meanwhile, in the process of cutting the anterior longitudinal ligament, the hook-shaped design can effectively hook the anterior longitudinal ligament, so that the slippage is prevented, and the effectiveness of the detachment of the anterior longitudinal ligament is improved.
In the whole total spine resection, the upper intervertebral disc, the lower intervertebral disc and the corresponding anterior longitudinal ligament of a diseased spine are incised from back to front by adopting a osteotome, so that the operation is not safe, the efficiency is low, and the time is the life in the operation with high difficulty in the whole total spine resection, so that the operation scalpel is designed by summarizing the experience in long-term clinical practice, the cutting efficiency of the anterior longitudinal ligament is improved, the operation risk is reduced, the operation time is shortened, and the operation success rate is improved.
