Problems solved by technology

[0010] (3) There are dead ends in the operation, and it is difficult to completely remove the nucleus pulposus, resulting in postoperative recurrence
[0011] (4) It is easy to operate repeatedly in the same path of nucleus pulposus resection, which affects the operation efficiency, etc.
[0015] However, manual operation is still required, only for assistance, to improve the manual operation to limit the movement of the optical fiber within a precise range, and there are still dead angles for operation

Embodiment 1

[0059] Embodiment 1: Using a fixed distance method.

[0060] The bendable curved swing arm assembly 5 adopted is a single-section structure, and the single section is connected with the guide tube 4 of the rear section through the shaft or its own material tapering. Thus, the elastic deformation of the shaft or the tapering of the own material can be used for the movement of the individual joints. Simultaneously, the small ring 8 that the front end of the flexible swing arm assembly 5 single joints is provided with is metal material, and the miniature camera 13 is installed in the guide tube 4 of the bendable curved swing arm assembly 5 single joints and its rear section. In this way, the small ring 8 at the front end of the flexible swing arm assembly 5 can be moved to a certain depth (safety depth) in the spinal canal to compress the protruding residual nucleus pulposus tissue, and control its pressure through the pressure sensor 12 to prevent the protruding residual pulposu...

Embodiment 2

[0062] Embodiment two: adopt constant pressure mode.

[0063] A bendable curved swing arm assembly 5 with a multi-section structure is adopted, and each section of the multi-section structure is connected with the guide tube 4 at the rear section through the shaft or its own material tapering. In this way, the elastic deformation of the shaft or the thinning of the own material can be used for the movement of a single joint. Simultaneously, the small ring 8 arranged at the front end of the single section of the bendable swing arm assembly 5 is a transparent material, and the miniature camera 13 is installed outside the guide pipe 4 of the single section of the bendable swing arm assembly 5 and its rear section.

[0064] During use, move the small ring 8 at the front end of the flexible swing arm assembly 5 to a certain depth (safety depth) in the spinal canal to compress the protruding residual nucleus pulposus tissue, and control its pressure through the pressure sensor 12 to...

Abstract

The invention discloses an intelligent nerve damage prevention projected nucleus pulposus resection operation mechanical hand. The intelligent nerve damage prevention projected nucleus pulposus resection operation mechanical hand comprises a mechanical hand main body; the mechanical hand main body comprises a connection mechanism; an elevating mechanism is installed on the connection mechanism; the elevating mechanism is connected to a guiding operation assembly through a guiding support; the working end of the guiding operation assembly is provided with a guiding tube; the front end of the guiding tube is of a pointed thorn shape; an arm swinging assembly capable of bending is arranged inside the guiding tube; a scraper and a ablation knife are arranged on a wall of an end of the front end of the arm swinging assembly. As a result, the intelligent nerve damage prevention projected nucleus pulposus resection operation mechanical hand has an independent scraper which can completely scrap a nucleus pulposus tissue which is in the intervertebral space, projected and tightly attached to the nerve to cause pressure and avoids a risk of generating nerves. The intelligent nerve damage prevention projected nucleus pulposus resection operation mechanical hand is simple in structure and is applicable to installation usage needs of most of robots, can adopt multiple kinds of ablation knives and can improve usage effects. An independent pressure sensor is arranged, so that a epidural tissue is not clamped.

Description

technical field [0001] The invention relates to a surgical manipulator, in particular to an intelligent nerve damage-preventing herniated nucleus pulposus resection surgical manipulator. Background technique [0002] As we all know, nucleectomy is an important way to treat lumbar disc herniation, cervical disc herniation, discogenic low back pain, spinal instability, spondylolisthesis and other diseases. Nucleus pulposus tissue, thereby reducing or eliminating the corresponding clinical symptoms. [0003] At present, nucleus pulposus resection is completed by manual operation of relevant instruments, and the methods can be summarized into the following three types: [0004] 1. Chemical methods: such as collagenase chemical fusion, ozone fusion, etc. [0005] 2. Physical methods: such as electrosurgical resection, radiofrequency ablation, laser repair, etc. [0006] 3. Mechanical methods: (1) nucleus pulposus forceps such as percutaneous incision and aspiration, naked eye ...
