Spine minimally invasive eccentric porous light-transmitting positioning and guiding device and using method thereof

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a spine minimally invasive eccentric porous light-transmitting positioning and guiding device and a using method thereof. The spine minimally invasive eccentric porous light-transmitting positioning and guiding device comprises a positioning and guiding body and a positioning and guiding needle, wherein one end of the positioning and guiding body is provided with a conical radian; the positioning and guiding body is provided with a plurality of first guiding needle through holes in the length direction; one first guiding needle through hole is formed along the central axis of the positioning and guiding body; the axes of the other first guiding needle through holes are perpendicular to different positions in the radial direction of the positioning and guiding body; a developing ring mounting hole is formed in the end, close to the conical radian, of each first guiding needle through hole; adeveloping ring is mounted in each developing ring mounting hole; and the positioning and guiding needle penetrates through the positioning and guiding body from the first guiding needle through holes. According to the spine minimally invasive eccentric porous light-transmitting positioning and guiding device and the using method thereof, the accurate position of a bone lesion is quickly found ina circle covering mode along different tracks with a single point as the reference, the size of the visual angle can be adjusted in the lesion position finding process, and the finding time of a nailfeeding point is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a spinal minimally invasive eccentric porous light-transmitting positioning and guiding device and a method for using the same. Background technique [0002] Minimally invasive spinal surgery refers to the surgical treatment of spinal diseases with minimal trauma and minimal physiological interference, so as to achieve the best surgical effect. It uses tiny incisions or puncture channels, and uses special instruments and devices. Under the monitoring of instruments or under the guidance of navigation technology, from the normal anatomical structure to the lesion, use various miniature manual or electric instruments and equipment, and complete the entire surgical process under visual conditions, so as to achieve better than traditional or standard spinal surgery incisions. Small size, less tissue trauma, less bleeding, high operation accuracy, definite effect, and fast pos...

AI Technical Summary

Problems solved by technology

[0003] Existing minimally invasive spinal surgery techniques mainly have the following deficiencies: (1) in the current minimally invasive spinal surgery, minimally invasive surgery is most concerned with effects such as small incision and fast operation time, but due to the small incision, it is impossible to directly view the spine. The surface condition of human bones can only be checked through X-ray equipment such as C-arm machine. In this way, patients will be exposed to multiple X-rays during the operation. X-rays will produce high radiation. Generally, doctors will wear radiation-proof lead However, the patient will be directly exposed to severe radiation, which will cause great damage to the body; (2) positioning guide wire (also known as positioning guide wire, positioning needle) is a common tool in minimally invasive spinal surgery. The process of pulling out from the bone requires external force. Due to the slender structure of the guide pin, it is easy to bend the guide pin during the process of inserting the guide pin into the bone and pulling it out from the bone, which will affect the service life of the positioning guide pin.
