Minimally invasive spinal surgery navigation assist device

Abstract

The invention discloses a minimally invasive spinal surgery navigation assist device which comprises a navigation positioning pin and a fixation clamp. The fixation clamp is used for fixating medicalnavigation instruments; external threads suitable to be screwed into the spine of a human body are arranged at the lower end of the outer wall of the navigation positioning pin; the fixation clamp isarranged on the upper portion of the navigation positioning pin. The minimally invasive spinal surgery navigation assist device has the advantages that the navigation positioning pin can be directly pierced into the body of a patient from the surface of the skin of the patient and can be screwed into the spine of the body of the patient, accordingly, wound on the surface of the body of the patientcan be omitted, suffering of the patient can be relieved to a great extent, and wound infection due to the wound on the surface of the body of the patient can be effectively prevented; the lower endof the navigation positioning pin is screwed into the spine of the body of the patient, is firmly fixated and is high in use reliability, clamp heads of the required medical navigation instruments arefixated by the aid of the fixation clamp, do not need to be pierced into the body of the patient and are far away from the body of the patient, radiation on the body of the patient can be reduced, accordingly, the minimally invasive spinal surgery navigation assist device is high in practicality, and good use effects can be realized by the minimally invasive spinal surgery navigation assist device.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a navigation aid for spinal minimally invasive surgery. Background technique [0002] In the traditional operation, the doctor generally opens a large wound on the patient's body surface, so that the anatomical structure of the operation site can be directly observed, so as to facilitate the operation and execution of the follow-up operation. Although this kind of surgical method is widely used, it still has certain defects. Specifically, opening a large wound will increase the pain of the patient, the cost of the operation is expensive, and the probability of wound infection is easy to increase during the operation. The remaining wound scars on the body affect the appearance of the body. [0003] For this reason, at this stage, a new surgical method is advocated, that is, minimally invasive surgery, which mainly uses endoscope or various imaging techniques to enable th...

Problems solved by technology

[0004] However, for minimally invasive spinal surgery, since the surgical site cannot be directly observed, the doctor must rely on the surgical navigation system to obtain the position of the human spinal surgery site and the spatial posture information of the surgical instrument. A wound of a certain size is opened on the surface, and the chuck of the medical navigation instrument connected with the required surgical navigation equipment is extended from the wound on the surface of the patient's body into the interior of the patient's body to clamp the patient's spine. Because the patient's spine is relatively large, the required The chuck of the medical navigation instrument used is also relatively large, so that the wound opened on the surface of the patient's body in the early stage is also relatively large, so that the patient's pain is inevitable, and because the corresponding wound size is relatively large, the immediate risk of infection is also increased. Yes, and when the chuck of the corresponding medical navigation instrument extends from the wound on the surface of the patient's body into the interior of the patient's body to clamp the patient's spine, it will also cause radiation to the patient's body, making it harmful to the patient's health
