Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a single-hole foldable, expandable, locking, double-channel spinal endoscope working sleeve device. Background Art

[0002] At present, there are two modes of spinal endoscopic surgery: single-channel and dual-channel. In single-channel spinal endoscopic surgery, the observation channel and the working channel are operated coaxially, and the field of view is relatively limited. The diameter of the working channel restricts the operation of conventional spinal surgical instruments. Although the dual-channel endoscope has the advantages of wide field of view and unrestricted instruments, there are still problems such as inadequate placement of surgical instruments and loss of instruments during surgery. For surgeons accustomed to single-channel endoscopes, the learning curve is relatively long, which is not conducive to the clinical application of this technology. Therefore, a dual-channel spinal endoscope working cannula that can achieve single-hole folding, expansion and locking under a single incision is needed, which can not only realize single-channel endoscopic operation, but also expand to a dual-channel endoscopic working cannula device by expanding the incision.
