Transparent full-visual U-shaped interbody fusion working channel and manufacturing method thereof

Abstract

The invention belongs to the technical field of medical instruments, and discloses a transparent full-visual U-shaped interbody fusion working channel and a manufacturing method thereof. A channel pipe and a handle are integrally formed through injection molding and carving, and the channel pipe and the handle are transparent; a connecting buckle is fixed to the handle, the channel pipe is locatedbetween soft tissues and spines, and an interbody fusion cage is fixed between the spines; and the outer side of the pipe wall of the channel pipe is an accurate position for the compression degree of outer blood vessels, nerves and dura mater, the scraping dynamic state of a soft vertebral plate in the pipe wall and implantation of the interbody fusion cage. A high-light-transmission and high-hardness resin material is adopted, the structure is simple, the cost is low, the basic requirement for serving as a medical-grade material is met, and the compression degree of the tissue outside the pipe wall, the position of the interbody fusion cage in the pipe wall and the scraping state of the soft vertebral plate can be observed in a minimally invasive interbody fusion operation process. Theoperation risk and difficulty are reduced, the operation efficiency is improved, and the health risk of medical staff and patients in the operation process is eliminated.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a transparent fully visible U-shaped intervertebral fusion working channel and a manufacturing method thereof. Background technique [0002] At present, digitalization and minimally invasive surgery are the signs of the development of spinal surgery and the direction of future spinal surgery development. With the development of spinal endoscopic technology, especially in recent years, UBE technology (unilateral dual-channel endoscopy) has attracted everyone's attention. UBE technology greatly improves the efficiency and safety of endoscopic surgery by separating the endoscope from the surgical channel. [0003] Traditional UBE technology often uses metal working channels in the minimally invasive intervertebral fusion surgery. The metal working channel has the following disadvantages: (1) It is opaque and completely blocks the surrounding tissue of the channel tube li...

Problems solved by technology

[0003] Traditional UBE technology often uses metal working channels in the minimally invasive intervertebral fusion surgery. The metal working channel has the following disadvantages: (1) It is opaque and completely blocks the surrounding tissue of the channel tube like a wall, so doctors cannot pass through it. The endoscope directly observes whether the important nerves, blood vessels, and dura mater around the channel are compressed and the degree of compression during the implantation of the intervertebral fusion device. It is also impossible to observe the operation in the channel, which virtually increases the difficulty and risk of the operation.

(2) X-ray fluoroscopy must be used to assist positioning during the operation, but X-rays cannot penetrate metal materials and can only assist in observation. Therefore, the intervertebral fusion cage cannot be directly located during the operation, and the state of the soft lamina scrape cannot be observed. To ensure the accuracy of the operation, and long-term exposure to X-rays has also caused damage to the health of patients and medical staff

[0005] (1) The existing metal working channel is opaque, and doctors cannot directly observe whether the important nerves, blood vessels, and dura mater around the channel are compressed and the degree of compression during the implantation of the intervertebral fusion device through the endoscope. It is impossible to observe the operation in the channel, which virtually increases the difficulty and risk of the operation

[0006] (2) X-ray fluoroscopy must be used to assist positioning during the operation, but X-rays cannot penetrate metal materials and can only assist in observation. Therefore, the intervertebral fusion cage cannot be directly located during the operation, and the state of the soft lamina scrape cannot be observed. To ensure the accuracy of the operation, and long-term exposure to X-rays has also caused damage to the health of patients and medical staff

[0007] The difficulty in solving the above problems and defects is: to solve the problem of the inability to directly observe the nerves, blood vessels, and dura mater through the endoscope during spinal surgery. except state
