Problems solved by technology

Therefore the current perforation operation of minimally invasive spinal surgery is to insert the puncture needle into the bone first, then the perforation drill bit is stretched to the affected part through the positioning of the open sleeve, and then the perforation is performed. Due to the limitations of the processing technology, the current perforation drill cannot turn in the specified direction, and the position of the perforation cannot be accurately determined. Therefore, the perforation surgery on both sides of the spine must be completed twice, which is inconvenient for the doctor to operate and prolongs the operation time.
This not only delays the operation time, increases the pain of the patient, but also increases the risk of cancer-causing lesions due to the long-term exposure of medical staff to X-rays

Embodiment 1

[0040] Such as figure 1 As shown, the minimally invasive perforation surgical tool 1 includes an open-circuit sleeve 11 and an open-circuit drill 12 disposed in the open-circuit sleeve 11 .

[0041] Please also refer to figure 2 and image 3 , the open-circuit sleeve 11 includes a sleeve body 111 and a core seat 112 that are connected to each other.

[0042] Please also refer to Figure 4 , the open circuit drill bit 12 includes a rod body 121 and a drill bit 122 , and also includes an elastic connecting rod 123 , and the drill bit 122 is connected to the rod body 121 through the elastic connecting rod 123 . The sleeve body 111 is provided with a drill bit outlet 113 , the rod body 121 is in the sleeve body 111 , and the drill bit 122 protrudes from the drill bit outlet 113 .

[0043]As mentioned above, the open-circuit sleeve 11 is used for positioning the needle, and the open-circuit drill bit 12 expands and contracts in the open-circuit sleeve 11 to perform perforation...

Embodiment 2

[0078] This embodiment provides a processing method of the minimally invasive perforating surgical tool 1 , which is used to manufacture the opening sleeve 11 and the opening drill 12 in the first embodiment. The open-circuit sleeve 11 is an integrally formed component, which is made by additive manufacturing. The open-circuit drill 12 is an integrally formed component, which is made by machining and grinding, and the open-circuit drill 12 is heat-treated.

[0079]The open-circuit sleeve 11 has a drill outlet 113 and a guide groove 1131. The open-circuit sleeve 11 is processed by an additive manufacturing method, which uses a computer to accurately control a high-energy laser beam or an electron beam to locally melt powdered metal materials and accumulate them layer by layer. According to the three-dimensional complex computer model, the solid parts with dense geometry are directly generated, so they are not limited by the processing structure. According to requirements, almos...

Abstract

The invention provides a minimally-invasive perforation surgical tool. The minimally-invasive perforation surgical tool comprises a path-opening sleeve and a path-opening drill bit arranged in the path-opening sleeve, wherein the path-opening sleeve comprises a sleeve body and a needle core seat which are connected mutually; the path-opening drill bit comprises a rod body and a drill bit and also comprises an elastic connecting rod, and the drill bit is connected with the rod body by the elastic connecting rod; a drill bit outlet is arranged on the sleeve body, the rod body is arranged in the sleeve body and the drill bit extends out of the drill bit outlet. The invention also provides a machining method of the minimally-invasive perforation surgical tool, which is used for manufacturing the path-opening sleeve and the path-opening drill bit; the path-opening sleeve is an integrally-molded member and is made of additional materials; the path-opening drill bit is an integrally-molded member and is manufactured by machining and ground, and heat treatment is carried out on the path-opening drill bit. The minimally-invasive perforation surgical tool and the machining method provided by the invention have the beneficial effects that the perforation efficiency is high, the perforation infection rate is reduced, the incision quantity is reduced, the safe and high-efficiency effects are achieved and the parts are integrally molded.

Description

technical field [0001] The invention relates to the field of perforating surgical tools, in particular to a minimally invasive perforating surgical tool and a processing method thereof. Background technique [0002] In traditional spinal surgery, a large incision is required to complete such an operation, so most of the back muscles have to be separated from the spine. In order to reduce the resulting severe pain, a large amount of painkilling drugs must be relied on, resulting in It has a lot of side effects, and the recovery time of the patient after the operation is very long, and it will also leave a large scar. [0003] Therefore, a minimally invasive spinal surgery with short operation time, quick curative effect and patient recovery has been developed at present. Minimally invasive spine surgery uses X-rays to show the injured part of the patient, uses special tools to perform perforation surgery, and then directly injects into the compressed vertebral body through t...
