This invention discloses a surgical guide for simultaneous implantation of maxillary sinus fluid extraction and internal lifting, belonging to the field of oral surgery technology. It includes a fixation device and a guide plate. The fixation device is fixed to the patient's dentition. A guide plate is located on one side of the fixation device, and an extension rod is located on the inner side of the fixation device, extending towards the missing molar. The guide plate is fixed to the extension rod and has an implant positioning hole at the missing dentition. A fenestration guide opening is located on the outer side of the patient's dentition. The fenestration guide opening guides the extraction of maxillary sinus fluid. Through this invention, the fixation device and the guide plate are connected and fixed. The guide plate has an implant positioning hole on the missing dentition and a fenestration guide opening pointing towards the patient's maxillary sinus. By setting the fenestration guide opening, the scope and depth of the fenestration can be clearly defined, significantly reducing the possibility of surgical errors and complications. Through the implant positioning hole on the guide plate, the internal lifting procedure is completed simultaneously, achieving precise implant placement.

The utility model relates to the field of minimally invasive surgery technology, specifically disclose a kind of heating mechanism and steam ablation equipment, heating mechanism is used to provide steam for steam ablation equipment, this heating mechanism includes water pipe and resistance wire, the material of water pipe is metal;Resistance wire is wound in the outer periphery of water pipe, resistance wire is communicated with external circuit and can produce heat, water pipe can absorb the heat generated by resistance wire;Resistance wire can generate alternating magnetic field and heat water pipe;Water pipe can at least heat the fluid passing through the inside of water pipe;At least one of resistance wire and water pipe is provided with insulating layer.The above-mentioned setting effectively improves steam production efficiency, improves operation efficiency.

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.

The utility model relates to the field of minimally invasive surgery technology, and specifically discloses a steam ablation system, which comprises a handle, a lead-in sheath, a puncture assembly and a host. The lead-in sheath is arranged on the handle and has a first channel; the puncture assembly has a steam channel, is arranged in the first channel and can pass out of the distal end of the lead-in sheath; and the host is used for generating steam. The inlet of the steam channel and the outlet of the host are in communication, and the steam can be sprayed out of the outlet of the steam channel. With the above structure, the operator can pass the lead-in sheath into the patient's body through the urethra by holding the handle, then operate the puncture assembly to pass out of the lead-in sheath and enter the tissue to be operated on, the steam provided by the host is sprayed out through the steam channel, thereby accurately ablates the tissue to be operated on, avoids removing the entire gland, reduces the influence of the operation on the patient and improves the patient's quality of life after the operation.

This utility model discloses an optical positioning device for orthopedic surgery, relating to the field of orthopedic surgical technology. It includes: a connecting rod, one end of which is connected to a robotic arm; a main structure, rotatably connected to the other end of the connecting rod via a rotating shaft, the main structure comprising a sleeve and a slider, the top of the slider being connected to the rotating shaft, the bottom of the slider being disposed within the sleeve, a sliding shaft passing through the sleeve wall, one end of the sliding shaft inside the sleeve abutting against the bottom of the slider, a spring being disposed between the bottom of the slider and the sleeve wall, and an operating part being disposed at the other end of the sliding shaft outside the sleeve; a tracer fixedly connected to the main structure; and a sleeve fixedly connected to a oscillating saw. This positioning device provides tracking, identification, and positioning capabilities, ensuring visibility during osteotomy. It is simple to operate, highly stable, flexible, and cost-effective, facilitating intraoperative implementation, saving surgical time, and improving surgical precision.

The application provides an eye surgery system and relates to the technical field of surgery. Since the air cylinder module, the perfusion module, the gas storage module and the suction module are independently arranged, and the air cylinder module, the perfusion module, the gas storage module and the suction module are detachably connected with the main frame, each module can be independently detached, and each module is independently arranged and does not have a main gas path that is interlaced with each other. When a certain module is damaged, the damaged module can be individually detached and replaced, thereby reducing maintenance costs. In addition, each module is independently arranged and can be individually detected in a modular manner, thereby reducing detection costs and solving the technical problem that the existing eye surgery system cannot be quickly repaired.
