Novel spine full-endoscope fusion implantation system

Abstract

The invention provides a novel spine full-endoscope fusion implantation system. The system comprises a front-view endoscope, a rearview endoscope, a fusion cage and a fusion cage implantation tool assembly, a clamping tube and the rearview endoscope are connected in a nested mode and then serve as a whole to be fixedly provided with a clamping tube handle, a fusion cage locker penetrates through the interior of the clamping tube and is fixedly connected with the fusion cage through a thread, a front-view endoscope regulator is connected with a combination body of a fore-view endoscope and a buckling seat in a nested manner, a knocking end cover is sleeved on the front-view endoscope regulator, and a combination body formed by the front-view endoscope regulator, the front-view endoscope, the buckling seat and the knocking end cover penetrates into the tail part of the fusion cage locker to make the forefront of the front-view endoscope reach the forefront of the fusion cage. The systemcombines one endoscope or two endoscopes with different specifications with a special tool according to different operations, monitors peripheral tissues under direct view of the endoscope in the whole process, and maximally avoids compression and tractive mechanical damage of the fusion cage to the peripheral important tissues.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a novel spinal total endoscopic fusion implantation system, which is used for percutaneous spinal endoscopic intervertebral fusion surgery and realizes fusion device implantation under full endoscopic monitoring. Background technique [0002] In recent years, with the development and popularization of minimally invasive surgery, surgical endoscope systems have been widely used in the fields of orthopedics, spine surgery, gynecology, urology and neurosurgery. The channels and eyepieces are designed with oblique angles to facilitate the use of thick and powerful surgical instruments. In order to ensure a clear view during the operation, the lens body integrates a liquid perfusion channel, a water outlet channel and an illumination light channel. The illumination light channel is usually composed of a bundle of optical fibers. In this way, the illumination light generated by the ext...

Problems solved by technology

MED technology can be operated under direct vision of the endoscope, with special surgical instruments. Compared with the previous open surgery, this technology has the advantages of small incision, small tissue stripping range, and less bleeding, and the surgical indications are similar to conventional open surgery; its disadvantages It is also obvious that due to the large diameter of the working channel, more tissues need to be removed during the operation, which seriously damages the bone and muscle tissue of the spine and affects the stability of the lumbar spine. After fusion, pedicle screws need to be implanted to fix the spine. For patients with good preoperative spinal stability or simple spondylolisthesis, the injury is large and the prognosis is poor

[0004] In recent years, on the basis of total endoscopic techniques for the spine, clinicians at home and abroad have used full endoscopic treatment of intervertebral discs and bony stenosis, and treated intervertebral discs and vertebral endplates under direct vision of the endoscope, and then implanted fusion cages. , but limited by the size, shape and volume of traditional fusion cages, the fusion cage implantation process cannot be operated under direct vision of the endoscope, and only protective sheaths or special fusion cages with special specifications and smaller sizes can be used, or larger fusion cages can be resected. To avoid mechanical damage to important tissues such as nerves and blood vessels during the fusion cage implantation process, causing serious complications, this type of technology endoscope cannot monitor the fusion cage implantation process, so it cannot be called a full-endoscopic technique. Endoscopic Assisted Spinal Fusion

[0005] The advantage of endoscope-assisted fusion technology is that the fusion channel is established under direct vision of the endoscope. Compared with the previous open or minimally invasive techniques, the damage to the tissue is less, the bleeding is less, and the perfusion of the visual field is clearer. Due to the small damage, some operators After the fusion cage is implanted, there is no need for fixation with nails and rods. However, due to the size of the fusion cage, it cannot be operated under the supervision of the endoscope during implantation. etc.) cause compression or traction injury; once the nerves and important blood vessels are damaged, the operation fails, the patient recovers poorly after surgery, and the prognosis is poor. In severe cases, a second open surgery revision is required, which greatly increases the burden on patients and the pressure on doctors and patients.

At the same time, this technology uses specially designed fusion devices and channels to reduce the occurrence of the above-mentioned problems. These shortcomings lead to risks and limitations in the promotion of this technology. The system will greatly enhance the security and promotion value of this technology
