Problems solved by technology

[0002] Anterior surgery can ensure complete decompression of the spinal canal under direct vision, and is an indispensable surgical approach in the field of spinal surgery. However, resection and decompression of the anterior vertebral body will lead to instability of the anterior column. Therefore, effective reconstruction Anterior column stability is a key factor for success in anterior surgery
Clinically, the materials used for cervical anterior column reconstruction include ilium, allograft bone, titanium mesh, artificial vertebral body, etc. The placement of the above materials at the decompression site of the anterior column of the cervical spine requires repeated cutting during the operation, which prolongs the operation time and increases the amount of blood loss , there is still a high risk of implant loosening and displacement after surgery

Embodiment 1

[0034] A real model of a supporting body after cervical vertebral body resection, the upper edge is located at the upper top of the real model body, the lower edge is located at the lower top of the real model body, the upper edge and the lower edge are connected into a whole through the real model body; the upper edge and the lower edge at a certain angle of inclination.

[0035] The upper edge is parallel to the lower endplate of the cephalic vertebral body, and the lower edge is parallel to the upper endplate of the caudal vertebral body.

[0036] The angle of the upper edge is the intersection angle between the lower endplate of the cephalic vertebral body and the vertical line of the upper endplate of the vertebral body to be resected after the preoperative simulation operation restores the physiological curvature of the cervical spine; the angle of the lower edge is the restoration of the cervical physiological curvature by the preoperative simulation operation After tha...

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and particularly relates to a supporting-body solid mold after the cervical vertebra body is excised and a making method. The supporting-body solid mold is characterized by comprising a solid mold body, an upper edge and a lower edge, the upper edge is located at the upper top end of the solid mold body, the loweredge is located at the lower top end of the solid mold body, and the upper edge and the lower are integrally connected through the solid mold body; a certain slant angle is formed between the upper edge and the lower edge. The supporting-body solid mold can be used for assisting in tailoring of a supporting body in the cervical anterior vertebra corpectomy technology, operation time is shortenedaccordingly, and complication such as post-operation prothesis loosening displacement is reduced; the supporting-body solid mold is simple in structure, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a real model of a support body after cervical vertebral body resection and a manufacturing method. Background technique [0002] Anterior surgery can ensure complete decompression of the spinal canal under direct vision, and is an indispensable surgical approach in the field of spinal surgery. However, resection and decompression of the anterior vertebral body will lead to instability of the anterior column. Therefore, effective reconstruction Anterior column stability is a key factor for the success of anterior surgery. Clinically, the materials used for cervical anterior column reconstruction include ilium, allograft bone, titanium mesh, artificial vertebral body, etc. The placement of the above materials at the decompression site of the anterior column of the cervical spine requires repeated cutting during the operation, which prolongs the operation time ...
