Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a coping saw control and protection device for excision of the whole centrum of backbone.
Background
In recent years, with the increase of incidence rate of spinal tumors and deformities and the improvement of spinal surgery concept and technology, the spinal total vertebral body resection has been widely used in the massive resection of spinal tumors and the orthopedic treatment of serious spinal deformities. Methods of corpectomy typically employ a wire saw to posteriorly distract the upper and lower discs of the targeted vertebral body. The prior art related methods for wire saw guidance and intraoperative spinal cord protection do have the following drawbacks. There is no tool available for controlling the position of the anterior wiresaw of the vertebral body and for protecting the nerve roots during the operation.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide a coping saw control and protection device for the excision of the whole centrum of backbone, can the position of effective control centrum the place ahead coping saw, can play fine guard action to the nerve root in the art again simultaneously, can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a coping saw control and protection device for excision of full centrum of backbone, includes first pull ring, coping saw, handle and cylindricality protection casing, the quantity of handle and cylindricality protection casing is two, the handle is located the up end of cylindricality protection casing, the medial surface middle part of handle be equipped with the communicating locating hole of cylindricality protection casing, the coping saw passes the locating hole and the cylindricality protection casing setting of setting at handle medial surface middle part, and the one end of coping saw is equipped with second and carries the pull ring, and the other end of coping saw is connected with the lock sleeve, first pull ring is connected with the couple through the connecting wire that sets up at its lateral surface, the couple corresponds the setting with the lock sleeve.
Furthermore, the handle is in threaded connection with a stud with a head through a threaded hole formed in the middle of the outer side face of the handle, the tail end of the stud with the head is located inside the positioning hole, and the scroll saw can be locked by the stud with the head.
Furthermore, the outer side surface of the cylindrical protective cover is provided with scale marks, and the arrangement of the scale marks facilitates the observation of the depth of the surgical incision.
Furthermore, the lower end of the outer side surface of the handle is provided with symmetrically arranged grip grooves, and the arrangement of the grip grooves facilitates the operation of medical personnel.
Compared with the prior art, the beneficial effects of the utility model are that: this a coping saw control and protection device for excision of full centrum of backbone, compact structure, convenient operation, occupation space is little during the use, conveniently washs and maintains, can die the coping saw lock through the tape head double-screw bolt, and the setting of scale mark has made things convenient for the observation of operation edge of a knife degree of depth, and the setting of cylindricality protection casing can avoid hindering when coping saw reciprocating motion and the nerve root plays fine guard action to the nerve root in the art.

fig. 2 is a front view of the present invention.
In the figure: 1 a first pull ring, 2 connecting wires, 3 hooks, 4 lock sleeves, 5 wire saws, 6 handles, 7 cylindrical protective covers, 8 stud bolts with heads, 9 a second pull ring and 10 scale marks.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a fretsaw control and protection device for vertebral column full centrum excision comprises a first pull ring 1, a fretsaw 5, a handle 6 and a cylindrical protective cover 7, wherein the number of the handle 6 and the cylindrical protective cover 7 is two, the handle 6 is positioned on the upper end surface of the cylindrical protective cover 7, a positioning hole communicated with the cylindrical protective cover 7 is arranged in the middle of the inner side surface of the handle 6, the fretsaw 5 passes through the positioning hole arranged in the middle of the inner side surface of the handle 6 and is arranged with the cylindrical protective cover 7, one end of the fretsaw 5 is provided with a second lifting pull ring 9, the other end of the fretsaw 5 is connected with a lock sleeve 4, the first pull ring 1 is connected with a hook 3 through a connecting wire 2 arranged on the outer side surface of the first pull ring, the hook 3 and the lock sleeve 4 are correspondingly arranged in a clamping way, the handle 6 is connected with a stud 8 through a threaded, can die the coping saw lock through taking the first double-screw bolt 8, the lateral surface of cylindricality protection casing 7 is equipped with the scale mark, and the lateral surface lower extreme of handle 6 is equipped with the handle recess that the symmetry set up, this coping saw control and protection device for the excision of the whole centrum of backbone, compact structure, convenient operation, occupation space is little during the use, convenient washing and maintenance, and the setting of cylindricality protection casing 7 can play fine guard action to the nerve root in the art.
When in use: through the edge with coping saw 5 around patient's backbone, then pass cylindricality protection casing 7 and handle 6 with lock sleeve 4, then will couple 3 joints to lock sleeve 4 on, can carry out the monoblock excision to the tumour of patient's backbone through the first pull ring of pulling 1 and, connecting wire 2, coping saw 5 during operation is fixed coping saw 5 by cylindricality protection casing 7, prevents that its off tracking from hindering patient's nerve root.
