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

Abstract

The invention relates to the technical field of medical instruments, and in particular relates to a spine minimally invasive symmetrical porous light-transmitting positioning and guiding device and ausing method thereof. The spine minimally invasive symmetrical porous light-transmitting positioning and guiding device comprises a positioning and guiding main body and a positioning and guiding needle; a conical radian is arranged at one end of the positioning guide main body; a plurality of first guide pin through holes are formed in the positioning guide main body in the length direction; oneof one first guide pin through holes is formed along the central axis of the positioning guide main body; the other first guide pin penetrating holes are symmetrically formed along the central axis ofthe positioning guide body; developing ring mounting holes are formed in the ends, close to the conical radian, of the first guide pin penetrating holes; developing rings are mounted in the developing ring mounting holes; and the positioning guide pins penetrate through the positioning guide body from the first guide pin penetrating holes. The positions of multiple nail feeding points can be selected while one-time X-ray illumination is met, and the accurate nail feeding points are found rapidly through fine adjustment, so that the searching precision of the nail feeding point is greatly improved, the searching time of the nail feeding point is shortened, and X-ray illumination frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a spinal minimally invasive symmetrical porous light-transmitting positioning and guiding device and a method for using the same. Background technique [0002] Minimally invasive spinal surgery technique avoids large incisions under certain medical risks, uses tiny incisions or puncture channels, uses special instruments and devices, and is guided by imaging equipment or navigation technology to reach the lesion from the normal anatomical structure. Various miniature manual or electric instruments and equipment can complete the entire operation process under visual conditions, so as to achieve smaller incisions, less tissue trauma, less bleeding, high operation accuracy, and definite results than traditional or standard spinal surgery. The purpose of fast functional recovery. [0003] Existing minimally invasive spinal surgery techniques mainly have the following deficie...

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.
