This utility model relates to medicine and can be used in neurosurgery. It is used as a means of accessing the intervertebral disc between the 5th lumbar and 1st sacral vertebrae at a 90-degree angle for laser vaporization. The utility model achieves the following technical results: 1. A minimally invasive, minimally invasive approach to the intervertebral disc at the L5-S1 level. 2. Allows to improve the effectiveness of treatment and achieve maximum pain relief in polysegmental lesions of intervertebral discs 3. Prior to this utility model, attempts were made to perform laser vaporization of the disc at the L5-S1 vertebral body level from anatomically inconvenient locations, which was accompanied by a long time interval, prolonged pain for the patient, the end of the electrode was not in the center of the nucleus pulposus, sometimes even on the cortical layer of the vertebral bodies, as a result of which the maximum effect of vaporization was not obtained, or aseptic inflammation of the bone tissue of the vertebrae was obtained. This utility model eliminates the above-mentioned issues, reducing vaporization time. The essence of this utility model is that, using this trocar and drilling stylet, we provide direct access to the L5-S1 intervertebral disc. Laser vaporization of this disc has not previously been performed due to its anatomical limitations.

A method and apparatus for designing a lateral approach surgical guide are disclosed. Embodiments provide a method and apparatus for designing a lateral approach surgical guide plate in which, if a maxillary sinus lifting surgery needs to be performed using a lateral approach method, the maxillary sinus is segmented from dental imaging data, a bone window is formed based on the segmented maxillary sinus, and the maxillary sinus lifting surgery is performed based on the bone window. The shape of the lateral approach surgical guide is then formed as a function of the thickness of the remaining bone in the bone window formation area and the stop of the cutting tool. Therefore, the guide plate for the lateral approach method can be quickly and accurately generated.

Some embodiments of the implant system are configured to be positioned from an anterior trajectory, an anterior lateral approach trajectory, or an anterior oblique approach trajectory relative to the bone. Some embodiments of the system are configured to be used in an anterior lumbar interbody fusion (ALIF) procedure.

The present embodiment relates generally to methods of performing surgical technique maxillary sinus floor augmentation with a lateral approach using a pre-portioned and ready pre-packaged bone graft composition in gelatin bags and method of producing gelatin bags. In addition the present inventions can be widely used in other medical fields such as dentistry, orthopedic surgery, spine surgery, plastic and reconstruction surgery, sport medicine, trauma surgery, phinoplasty surgery and veterinary.

Provided is a height-adjustable interbody fusion cage for an oblique lateral approach, comprising a body having a frame structure. A first upper blade is movably disposed on one end surface of the body, and a second lower blade is movably disposed on the end surface of the body opposite to the first upper blade. Opposite side surfaces of the body are provided with positioning holes. The two positioning holes are located on the same straight line in the horizontal direction, and the center lines of the two positioning holes are also on the same straight line. The end surface of the body adjacent to the positioning holes is a threaded end surface, and the threaded end surface is provided with a threaded hole.

This utility model discloses a waterproof drainage device for water-based spinal endoscopic lateral approach surgery, relating to the field of water-based spinal endoscopic lateral approach surgery technology. This utility model aims to solve the problems of existing waterproof membranes and devices for water-based spinal endoscopy, which lack standardized specifications and are all custom-cut and set by the surgeon, leading to prolonged operation time, inconsistent quality, and wet towels on the back of prone patients, easily causing infection in the surgical area. Furthermore, poor drainage of fluids generated during prone lateral approach surgery can flow along the membrane and endoscope to the sterile towels laid on the operating table. If the patient sleeps on a wet operating table, it can cause intraoperative colds, postoperative shivering, even fever, and slow recovery. The fluid can also contaminate the sterile environment of the operating room floor. This utility model includes a three-sided foldable side panel and a three-sided waterproof membrane, with the three-sided waterproof membrane placed on the three-sided foldable side panel.
