[0036] Specific principle: When in use, there are two pipes, the diameter of the flushing pipe is 0.5mm, which is relatively fixed; the diameter of the suction pipe is 4mm, which is as light and thin as possible under the premise of ensuring that the maximum negative pressure will not collapse, and can be replaced; three lines; a bipolar coagulation A line on the suction device, through the assistant controller, as the A pole of the bipolar coagulation line. Two lines on the flushing device, through the assistant controller, one is used as the bipolar coagulation B line; the other is used as a monopolar electric knife line. It is solved by a combination of multiple functions. The main body of the instrument operation part includes a suction device and a flushing device, and the two are independently set to meet the needs of flushing and suction at the same time in certain special cases; the functions of electrocoagulation hemostasis and clamping are completed through a bipolar-like structure; the cutting is completed or a similar cutting effect is achieved by introducing an electrode dissecting needle. The structures cooperate and share with each other to minimize the volume of the head end of the instrument operating part. Design plan: The instrument consists of two parts: the instrument operating part and the assistant control connection device. The instrument operating part is controlled by the operator to complete functions such as suction, flushing, hemostasis, clamping, stripping, cutting or shearing. The assistant control connection device consists of an assistant controller and pipes (including suction and flushing) and lines connected to it. The assistant controls the flushing through the controller to complete the conversion of the monopolar electrosurgical unit and the bipolar electrocoagulation circuit and the control of the monopolar electrosurgical unit; considering the characteristics of endoscopic operation, the instrument operating part is designed to be gun-shaped; considering the different depths of the working distance and the intraoperative situation, the endoscopic instrument has two specifications of length: 198 and 218mm; working distance: 98 and 118mm; handle length: 100mm; suction device has two specifications of 2.0 and 3.0mm; the working part, especially the head end, is minimized as much as possible to save space under the premise of meeting the operation needs; the suction device is gun-shaped to avoid mutual influence between the endoscope and the instrument during operation; the operator controls and adjusts the suction force of the suction device through the pressure control hole on the control handle; at the same time, the blocked suction device pipeline can be unblocked with a probe through the pressure control hole; the flushing device is roughly similar to the suction device and has a symmetrical structure, and the Y-shaped cavity solves the problem of flushing pipeline and monopolar probe introduction; flushing port The opening is located 2 cm above the head end of the flushing device, which is convenient for flushing the endoscope lens to maintain a clear field of vision. At the same time, the outlet on the dissecting needle is convenient for fixing the dissecting needle and reducing the volume of the operating head end; the surgical flushing opening and closing and flow rate are controlled by adjusting the pressure through a rotary switch and a pressurized bag; the bipolar coagulation function uses the basically corresponding suction device and flushing device as the basic bipolar electrode structure, and the exposed head ends of the two are used as the coagulation contact surface; the two are connected and fixed through the insulation at the tail end, and at the same time provide the force for the opening of the instrument; the two are connected to each other through the circuit, and the bipolar coagulation line is connected or disconnected through the assistant controller, and the bipolar coagulation is controlled by the operator through the foot switch; the monopolar electrosurgery knife passes through the straight part of the Y-shaped cavity of the flushing device, and the monopolar dissection probe is introduced from the tail end; the coagulation dissection needle is long and has a diameter of about 0.7 mm and a length of 108 mm or 128 mm. The head end is needle-shaped and the tail end is bent. It is introduced from the hole reserved in the handle of the flushing device.The line connection is completed by contacting the probe with the inner wall of the cavity, and the monopolar and bipolar lines are made independent and non-interfering through the assistant controller; the extension and retraction of the probe is completed by pushing and pulling the tail of the monopolar probe; the probe head is extended during work and fixed by the combined instrument head end; the monopolar electric knife is retracted into the flushing channel for protection when not in use; the head end of the instrument operation part is circular, the head end of the suction device is circular, and the head end of the flushing and dissecting device is arc-shaped, which is opened or closed by the circulating opening and closing device. In the closed state, the head end of the instrument operation part is circular, which can clamp and fix the dissecting needle. The line change is completed by the assistant control device as a monopolar electric knife for dissection and cutting; the inner side of the head end is exposed 2mm, and when separated, the line change is completed by the assistant control device, converted to bipolar electrocoagulation, and rapid electrocoagulation hemostasis. Suction and flushing can be completed at the same time to ensure a clear surgical area. The head of the working part can quickly complete multiple functional transformations to improve work efficiency; the tail of the instrument operation part is 100mm long and gun-shaped, which is staggered for the hands approaching during operation; in addition to the suction pressure control hole and the monopolar electrode introduction hole, there are also interfaces for suction and flushing pipes; the middle part of the handle is a circulating opening and closing device; three wires are connected to the tail connection; the design of the circulating opening and closing device: the purpose of designing the circulating opening and closing device is to solve the problem of opening and closing control of the head of the instrument operation part; in the open state, the instrument provides elastic force for the opening of the instrument through the tail connection; the locking is completed by pressing the tail of the instrument operation part, at this time the instrument operation part is tightly fitted to save space; press again to unlock, and the opening and closing of the instrument cycle is carried out, which is convenient for the opening and closing of the head end, stable clamping force, reduced secondary damage, and physical strength. The circulating opening and closing device ensures that there will be no circuit short circuit at the contact part through material or insulation fixation; the assistant observes through the endoscopic image away from the surgical area, cooperates with the intraoperative control of flushing, completes the conversion of monopolar and bipolar electrosurgical lines, monopolar electrocoagulation control, and cutting control. The design is heart-shaped, which is in line with human functional science and can play a suggestive role. The flushing knob is placed at the apex of the heart to save space and facilitate operation. The circuit conversion is completed by pushing the circuit slider up and down. The monopolar electrosurgical knife is inserted into the monopolar electrosurgical knife access point, and the monopolar electrosurgical knife is controlled by the assistant.
