Embodiment Construction

[0032] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0033] Such as Figure 1 to Figure 3 As shown, the unilateral dual-channel endoscopic technique assists the insertion of the intervertebral fusion cage into the cannula hook, including the cannula 1 used to assist the implantation of the intervertebral fusion cage.

[0034] A guide post 5 for assisting insertion into the wound is fitted on the cannula 1 .

[0035] The head end of the cannula 1 is also provided with a protective plate 2 for protecting nerve tissue.

[0036] The end of the protective plate 2 is also fixedly connected with a limiting plate 4 for extending into the intervertebral space.

[0037] A t...

Abstract

A single-sided dual-channel endoscopic technical assisting interbody fusion cage imbedding casing hook relates to the technical field of single-sided dual-channel endoscopy. The hook comprises a casing for assisting interbody fusion cage imbedding. The hook solves the problem in the prior art that the traditional intervertebral minimally invasive aid only pursues how to place an interbody fusion cage, and neglects hindering and damage to the human body caused in the placement process.

Description

technical field [0001] The invention relates to the technical field of unilateral dual-channel endoscopy, in particular to a unilateral dual-channel endoscopic technique assisting insertion of an intervertebral fusion cage into a cannula hook. Background technique [0002] Lumbar degenerative diseases are common in spine surgery outpatient clinics. At present, minimally invasive spinal endoscopic technology relieves patients' pain with minimal trauma, and its development is becoming more and more mature. In particular, the single-channel transforaminal endoscopic technique has rapidly become popular across the country. However, due to the single channel, the flexibility and mobility during surgery are poor. The scope of the operative field is greatly limited. In addition, the single-channel endoscope must be equipped with special small-sized instruments. Due to its slender size, its efficiency in treating lesions is low. Therefore, single-channel transforaminal endoscopy ...
