Bipolar electrosurgical forceps are provided with dual irrigating tubes that deliver irrigating liquid to the opposed surfaces of the tips of the forceps to prevent the sticking of body tissue to the tips. To reduce the manufacturing costs of the forceps and enable the forceps to be single use, disposable forceps, each tube of the dual irrigating tools is a plastic tube adhered along one of the opposing surfaces of the pair of forceps arms. Each tube also has a flat nozzle at the distal end of the tube that disburses irrigating liquid across the opposed surfaces of the forceps arm distal and tips.

A colpotomy system includes a colpotomy cup, an electromagnet that is coupled to the colpotomy cup (thereby forming an electromagnetic colpotomy cup), and a bipolar electrocautery wand configured for use with the colpotomy cup and electromagnet. The electromagnet is used to generate an inwardly directed force, known as the Lorentz force, to direct the electrocautery wand towards the center of the colpotomy cup. This allows the physician to direct the wand towards the center of the uterine axis and away from the bladder as well as other surrounding structures in the pelvic cavity.

The invention discloses a push broach structure of bipolar coagulation forceps and the bipolar coagulation forceps, and belongs to the technical field of electrosurgical instruments. The push broach structure of the bipolar coagulation forceps is used for driving a cutting blade of a cutting mechanism and comprises a trigger, a connecting mechanism and a sliding block which are arranged on a support, the sliding block is connected with the support in a sliding mode and used for abutting against the end of one end of a cutter bar of the cutting mechanism, and the trigger is in linkage with the sliding block through the connecting mechanism; when the trigger moves relative to the support, the connecting mechanism drives the sliding block to slide relative to the support so as to push the end portion of one end of a cutter bar of the cutting mechanism, so that a cutting blade located at the other end of the cutter bar is driven to be pushed in the first direction, a bar assembly with the cutter bar can be directly detached under the condition that the sliding block is not detached, and more convenience is achieved. Meanwhile, when the trigger moves relative to the support, the connecting mechanism drives the sliding block to slide relative to the support so as to push the end portion of one end of a cutter bar of the cutting mechanism, so that a cutting blade located at the other end of the cutter bar is driven to be pushed in the first direction, and the cutter bar can be stably pushed under the condition that the sliding block and the cutter bar are not connected together; therefore, reliable cutting of tissues is realized.

The invention provides a surgical robot system with a nerve detection function and a control method thereof. The system comprises an intraoperative nerve monitor, a high-frequency energy generation device, a laparoscopic robot, a function switcher, a console and a processing device. The intraoperative nerve monitor is used for outputting nerve electrical stimulation signals and collecting nerve information. A bipolar coagulation instrument and an endoscope are arranged on the laparoscopic robot; the endoscope is used for collecting a target image of a surgical site of a patient. The function switcher is used for outputting a nerve electrical stimulation signal when it is not detected that the high-frequency energy generating device outputs the high-frequency energy. The console is used for controlling the laparoscopic robot to execute laparoscopic surgery. And the processing device is used for fusing the target image and the neural information to obtain a fused image, and sending the fused image to the console so as to display the fused image in the display device. In this way, a doctor can watch the image and neural information collected by the endoscope at the same time through the console, and the safety of an operation can be improved.

A forceps system for sealing a blood vessel can include a first jaw and an opposing second jaw. At least one of the first and second jaws includes at least a first electrode having first and second electrode portions that are laterally separated to permit electrical isolation between the first and second electrode portions, and the first and second electrode portions are independently addressable to permit individual testing by the first and second electrodes portions of a blood vessel characteristic. This can help permit individual testing of each side of a target seal region of the blood vessel.

The present application relates to the technical field of medical devices, in particular to a bipolar electrocoagulation separating forceps for open surgery. The handle of the present application is connected with an electrocoagulation forceps head, which comprises a first forceps head and a second forceps head connected movably like scissors. The handle comprises a first handle connected with the first forceps head and a second handle connected with the second forceps head. A blade pushing mechanism and a blade assembly are arranged in the first handle. The blade pushing mechanism is connected with the blade assembly. One end of the blade assembly is located in the first handle and the other end is located in the electrocoagulation forceps head. A forceps head connecting wire electrically connected with the first forceps head and the second forceps head is arranged in the second handle. The bipolar electrocoagulation separating forceps is easy to operate, has good effect on tissue electrocoagulation, and can effectively cut and separate the tissue after electrocoagulation, so that the operator can complete the tissue electrocoagulation and separation operation without changing other surgical instruments during the operation.

The application provides an intracranial hematoma removing special ventriculoscope, and relates to the technical field of medical devices, which comprises a soft insertion part, a bending adjusting part, a double-path imaging part, an image display part, an auxiliary sealing part and a guiding and positioning part; the bending adjusting part is installed on the soft insertion part; the double-path imaging part is installed on the soft insertion part, is used for observing the surgical field in front of the puncture path, and is also used for observing the side wall of a hematoma cavity and surrounding brain tissue; the auxiliary sealing part is installed on the soft insertion part; the guiding and positioning part is installed on the soft insertion part, is used for guiding a bipolar coagulation, a suction tube and a flushing tube, and is also used for preventing the bipolar coagulation, the suction tube and the flushing tube from falling off; the navigation induction coil is matched with an electromagnetic navigation device to realize accurate positioning and guide the accurate advancement of the soft insertion head; the problem that there is no real-time position feedback in operation and the puncture path is deviated due to brain tissue displacement is solved.

This invention provides a bipolar electrocoagulation device with suction function, comprising: a handle; a guide tube detachably mounted on the handle, with electrocoagulation forceps hinged inside the guide tube; a traction mechanism mounted inside the handle, the traction mechanism including a traction column slidably mounted inside the handle; and a suction mechanism mounted inside the handle, the suction mechanism including a suction box and a first sealing plate, the suction box being fixedly mounted on the handle, and the first sealing plate being slidably mounted inside the suction box. This invention solves the technical problem in the prior art where, to cope with smoke interference, bipolar electrocoagulation forceps are typically used in conjunction with a suction device. This requires medical personnel to operate the bipolar electrocoagulation forceps with one hand for tissue processing and independently operate the suction device to absorb the smoke with the other hand. In the stressful surgical environment, this requires a high degree of coordination between both hands, placing stringent demands on the medical personnel's bimanual coordination ability, increasing operational difficulty, fatigue, and the risk of error.
