Double-channel spinal endoscope visual abrasion drill protective sleeve

Abstract

The invention belongs to the technical field of surgical instruments, and discloses a double-channel spinal endoscope visual abrasion drill protective sleeve. The protective sleeve is provided with aprotective sleeve main body, and the protective sleeve main body is integrally arranged with the protective tip of a front end abrasion drill; and the protective sleeve main body is connected to a sheath pipe through a connecting and fixing part, and the sheath pipe is fixedly connected to an abrasion drill handle. By adopting the design of the transparent protective sleeve, soft tissues can be effectively isolated from the abrasion drill rotating at a high speed; and the protective sleeve is firmly connected to the metal sheath pipe through the thread design and can move along with the movement of the abrasion drill, so that the efficiency of abrading and removing bone tissues is improved. The transparent and firm material design can ensure the real-time and dead-angle-free monitoring ofthe working state of the abrasion drill under a full endoscope. The protective sleeve has the advantages of simple structure, good fixing performance and low cost.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, and in particular relates to a dual-channel spinal endoscope visualization drill protection sleeve. Background technique [0002] At present, the electric drill is an indispensable bone tissue grinding tool in spinal surgery. Its main working principle is to make the drill bit driven by the motor rotate at a high speed and contact the hard bone tissue, and then grind the bone tissue to facilitate the exposure of the bone tissue. Other deep tissues (intervertebral discs, nerves, etc.) and perform corresponding operations (such as decompression of nerve tissues, resection of diseased tissues, etc.). Compared with traditional rongeurs that manually remove lamina and other bone tissues, such as the compression of the underlying nerve tissue and the fatigue of the operator, the wide application of electric drills enables spinal surgeons to perform the surgery easily and relatively safely....

AI Technical Summary

Problems solved by technology

The disadvantage of the above technique is that the protector is not connected with the handle of the burr, the protector cannot be fixed stably, and cannot move with the burr, and the efficiency of bone tissue treatment is low; the ligamentum flavum is often tightly connected under the lamina, and the isolation plate may not be inserted Between the bone and the nerve structure; the shape of the transitional junction is inefficient in blocking soft tissue; most importantly, the non-transparent design of the transitional junction has a dead angle for observation under the endoscope, and real-time operation under full endoscopic monitoring cannot be achieved , there is a certain security risk

[0005] Through the above analysis, the existing problems and defects of the prior art are as follows: (1) There are new problems and risks in the use of the burr under the endoscope. Because the operation pipeline has limited stripping of the soft tissue on the surface of the bone tissue, the high-speed rotating burr and the front The connecting rod is easy to stir and entangle the surrounding muscles and other soft tissues, which not only causes excessive soft tissue damage, but also leads to unclear surgical field of vision and potential nerve damage risk

[0006] (2) The protector of the prior art is not connected with the handle of the burr, the protector cannot be stably fixed, and cannot move with the movement of the burr, and the efficiency of bone tissue treatment is low; the ligamentum flavum is often closely connected under the lamina, and the isolation plate It may not be possible to insert between the bone and the nerve structure; the shape of the transitional junction is ineffective in blocking soft tissues; and there is a dead angle for observation under the endoscope at the transitional junction, which cannot be operated in real time under full endoscopic monitoring, and there are certain safety hazards

[0007] The difficulty in solving the above problems and defects is: to solve the problem that the burr drill under the dual-channel spinal endoscope is easily entangled in soft tissue. The drill moves as it moves; how to design a burr guard that can go from the tip of the burr to the full length of the burr connecting rod to avoid soft tissue entanglement, but at the same time should not affect the use of the burr, i.e. the burr is in at least one lateral direction It should be exposed so as to be able to contact and process bone tissue; how to design a burr guard that can achieve full visualization, that is, a transparent design, so that bone tissue can be safely ground under endoscopic monitoring
