The connecting accessory 106 is connected to the long pull rod tailstock 202. By providing an inner pull rod 301 and a hollow fine-tooth grasping forceps a308 and a hollow fine-tooth grasping forceps b312, an insulating tube 302 is sleeved on the outer side of the inner pull rod 301, and the outer side of the insulating tube 302 A metal outer tube 303 is sleeved, and a heat shrink tube 304 is sleeved on the outer side of the metal outer tube 303.

[0027] Secondly, the end of the needle-type bipolar electrocoagulation wire 4 is passed through the middle hole of the through shaft 104, and then the wire is divided and welded to the groove of the bipolar brass conductive block 203 and the outer circumference of the bipolar brass conductive ring 204 respectively. After completion, the bipolar brass conductive ring 204 is slid into the tail of the assembly c, slid to the outside of the bipolar metal conductive ring 205 part and wrapped, and the center hole of the bipolar brass conductive block 203 is inserted into the outer circumference of the long pull rod tailstock 202, so as to form an assembly d;

[0028] Finally, the sealing head 103 is inserted into the corresponding position of the motor hole of the main body fixed handle 101, the connecting accessory 106 is inserted into the corresponding position of the movable handle 201, and the long pull rod tail seat 202 of the assembly d is inserted into the connecting accessory 106, the assembly d, the connecting accessory 106 and the movable handle 201 are embedded in the main body fixed handle 101, and the matching position of the through shaft 104 and the main body fixed handle 101 is adjusted, and finally the ligand fixed handle 105 is embedded in the relevant matching column of the main body fixed handle 101, and ultrasonic welding is performed to avoid damage to the plastic parts of the instrument itself during the welding process, reduce the difficulty of assembly, and reduce the cost loss of parts.

[0029] Embodiment 2:

[0030] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that the bipolar electrocoagulation forceps used in the prior art have circuit boards connected by pin welding. When assembling its parts and instruments, since most of the parts are made of plastic, the welding process can easily cause damage to the plastic parts of the instrument itself, thereby increasing the assembly cost of the device. However, when using the device, medical staff usually need to control and adjust the clamping space of the device to meet the treatment needs of different sized parts.

[0031] In order to adapt the device to the treatment of different sizes of parts, combined Figure 1 and Figure 3 as well as Figure 4 As shown, an adjustment mechanism 2 with applicability is proposed, by setting a movable handle 201 and a rotating wheel 206, one end of the inner pull rod 301 is fixedly connected to the long pull rod tailstock 202, the tail of the rotating wheel 206 is installed with a bipolar brass conductive ring 204, a bipolar metal conductive ring 205 is installed between the bipolar brass conductive ring 204 and the tail end of the rotating wheel 206, a bipolar brass conductive block 203 is installed on the long pull rod tailstock 202, the bipolar metal conductive ring 205 is aligned with the threaded hole of the tail end of the rotating wheel 206, and a locking screw 207 is installed to fix it, by controlling the movable handle 201 to rotate along the shaft hole of the main fixed handle 101, after the lifting and lowering operations are performed, since the connecting accessory 106 is connected to the long pull rod tailstock 202, The long pull rod tailstock 202 is connected to the inner pull rod 301, and the inner pull rod 301 is connected to the hollow fine-toothed grasping forceps a308 through the inner pull rod column pin 305. When the movable handle 201 makes a lifting movement, the hollow fine-toothed grasping forceps a308 gradually opens due to the presence of the insulating column 307 between the hollow fine-toothed grasping forceps b312 and the insulating seat 311. The hollow fine-toothed grasping forceps b312 will also gradually open due to the relationship between the insulating column 307 and the clamp head column pin 306. When making a descending movement, it will close until the movable handle 201 cannot descend. This makes it convenient for medical staff to change the clamping space between the hollow fine-toothed grasping forceps a308 and the hollow fine-toothed grasping forceps b312 by pressing the movable handle 201, thereby improving the applicability of the device.

[0032] The end of the needle-type bipolar electrocoagulation wire 4 passes through the middle hole of the through shaft 104 and then splits into two sections, and the two sections of the wire are respectively connected to the groove on the bipolar brass conductive ring 204 and the outer cylindrical surface of the bipolar metal conductive ring 205. The components constituting the device are all disposable items to avoid cross-infection of viruses and ensure sanitary conditions. When the forceps head is closed, the needle-type bipolar electrocoagulation wire 4 is connected to the power supply, and the current path enters from one of the poles of the needle-type bipolar electrocoagulation wire 4, passing through the needle-type bipolar electrocoagulation wire 4-bipolar brass conductive block 203-long pull rod. Tail stock 202—inner pull rod 301—inner pull rod pin 305—hollow fine-tooth grasping forceps a308—hollow fine-tooth grasping forceps b312—clamp head pin 306—clamp head seat 309—metal outer tube 303—locking screw 207—bipolar metal conductive ring 205—bipolar brass conductive ring 204—needle-type bipolar electrocoagulation wire 4; if in the open state, since the hollow fine-tooth grasping forceps a308 and the hollow fine-tooth grasping forceps b312 are not connected, current cannot flow from either pole, thereby realizing the function of the bipolar forceps allowing current to flow through.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
