Hard mater protection plate with single-side admission passage and opposite-side pressure reduction

Abstract

The invention discloses a single-side admission passage opposite-side pressure reduction dura mater protection plate which comprises an opposite-side protection mechanism, an auxiliary stress mechanism, an internal reinforcing mechanism and a taking anti-skid mechanism, the auxiliary stress mechanism is arranged at one end of the opposite-side protection mechanism, and the internal reinforcing mechanism is arranged in the opposite-side protection mechanism. And a taking anti-skid mechanism is arranged at the top end of the auxiliary stress mechanism. According to the single-side admission passage opposite-side decompression dura mater protection plate, supporting assistance is achieved through the admission passage baffle on the same side in the minimally invasive surgery, the arc-shaped angle adjusting design is adopted between the main pressing plate and the protection plate, the bending angle is larger, minimally invasive surgery operation can be better conducted after admission passage supporting decompression, shielding is provided for the dura mater, and the dura mater protection plate is more convenient to use. The protective plate is simple in structure and convenient to use, can effectively avoid the situation that the bone rongeur bites the epidural sac in the epidural due to misoperation, plays a protective effect in the approach operation process, and effectively reduces injury to the approach position in the operation process and improves the safety rate of the operation due to the fact that the front end of the protective plate is designed to be in the shape of the arc head.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgery, in particular to a unilateral approach contralateral decompression dural protective plate. Background technique [0002] Minimally invasive surgery, as the name implies, is surgery with minimal trauma, which refers to the use of modern medical instruments such as laparoscopes and thoracoscopes and related equipment. A new technology for performing surgery, minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. With the development and progress of science and technology, the concept of "minimally invasive" has penetrated into various fields of surgery. The system is not limited to endoscopes, but also uses interventional methods, such as spine surgery, orthopedics, and other methods, such as microsurgery, which is widely used in hand surgery and other phenomena. [0003] At present, in the process of minimally invasive surgery on the marke...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a unilateral approach contralateral decompression dura mater protection plate, in order to solve the process of minimally invasive surgery proposed in the above-mentioned background technology, especially when performing the minimally invasive surgery approach of the spine, For one-sided approach, it is necessary to provide decompression support to the opposite side of the approach, and the dura mater on the opposite side cannot provide certain protection for the dura sac and its parts due to lack of good protection measures. It may cause problems such as the part of the intradural ink sac being bitten by the rongeur
