The puncture needle robotic arm, syringe robotic arm, and level are connected to a main control module circuit located within the main body. The robotic system disclosed in this invention can reduce operation time, decrease the physical and psychological burden on patients, improve the efficiency and safety of the entire surgical process, reduce human error and intraoperative complications, and is suitable for the diagnosis and treatment of pulmonary nodules and other lung diseases.

The utility model discloses a plasma operation electrode for treating rhinitis, and relates to the technical field of medical instruments. In order to solve the problems that solution instillation and waste suction are inconvenient and the ablation effect is poor in the existing rhinitis plasma ablation electrode, the following technical scheme is provided: the rhinitis plasma ablation electrode comprises an electrode tip, an electrode rod, a handle and a cable joint which are connected in sequence, the electrode rod comprises an inner tube and an outer tube, the tail end of the electrode tip is arranged between the inner tube and the outer tube, and the cable joint is connected with the handle. The inner tube and the outer tube extend into the handle; the tail end of the handle is connected with an instillation tube and a suction tube; an instillation hole is formed in an insulating head, close to the electrode tip, of the front end of the outer tube, and the instillation hole is communicated with the instillation tube through a gap between the inner tube and the outer tube; a suction hole is formed in the middle or the rear portion of the upper end face of the insulating head and communicated with the inner tube, and tissue generated in the operation is sucked out through the suction tube. According to the utility model, the performance of an operation tool is improved, the safety, efficiency and effect of an operation are improved, and a more effective and safer method is provided for treating rhinitis.

The utility model provides a bendable nerve ventricle endoscope, and relates to the technical field of endoscopes. A bendable nerve ventricle endoscope comprises a handle, the handle is provided with an insertion tube, a bent snake bone is arranged at the end, away from the handle, of the insertion tube, a tip is arranged at the end, away from the insertion tube, of the bent snake bone, and a camera is arranged at the tip; the bent snake bone is hollow, two pull wires are oppositely connected to the inner side wall of the front end of the bent snake bone, the pull wires penetrate through the insertion tube and extend into the handle, and the handle is provided with a traction assembly used for pulling the pull wires. By the adoption of the cranial nerve endoscope, the problems that a traditional cranial nerve operation is large in trauma and large in operation difficulty can be solved, the endoscope is simple in structure, convenient to use, small in trauma and capable of being bent easily, lesions which cannot be displayed by a hard endoscope can be observed, the operation can be carried out at the same time, a safer and more reliable technical means is provided for the cranial nerve operation, and popularization and application are facilitated. The operation quality is improved, and the operation complications are reduced.

The utility model discloses a double-cavity balloon catheter structure with non-coaxial double cavities, which comprises a catheter body with double cavities and a balloon arranged at the far end of the catheter body, the catheter body comprises an inner tube and an outer tube, the inner tube is arranged in the inner cavity of the outer tube, the tube cavity of the inner tube forms a guide wire cavity, a pressure-resistant balloon charging and discharging tube is arranged between the inner tube and the outer tube, and the balloon charging and discharging tube is arranged in the outer tube. The balloon charging and discharging pipe is provided with a balloon charging and discharging cavity, the far end of the balloon charging and discharging pipe is connected with an inner cavity of the balloon, so that the balloon charging and discharging cavity is communicated with the inner cavity of the balloon, the balloon is charged and discharged, and the inner wall of the outer pipe is tightly attached to the outer wall of the inner pipe. Compared with the prior art, when the balloon is filled, the filling pressure of the balloon does not affect the guide wire cavity, it is guaranteed that the guide wire cavity is not deformed due to extrusion of peripheral pressure, passing of a guide wire and other instruments in the guide wire cavity is not affected, the use risk is reduced, the success rate of an operation is improved, and the probability of occurrence of operative complications is reduced.
