Compared with the prior art, the application has the beneficial effects that:
the mutual insulation of the first electrode and the second electrode means that the exposed parts of the first electrode and the second electrode are not directly contacted and conducted during operation; i.e. a channel extending from the proximal end to the distal end of the second electrode. The distal ends of the first electrode and the second electrode are parallel and level and are insulated, when the electrodes are in contact with tissues, the two electrodes are conducted by the tissues to form a loop, and the tissues are burnt by current to dehydrate and denature the tissues, so that the hemostatic effect is realized. Because the through groove is arranged on the second electrode (loop pole), the first electrode (action pole) can be completely embedded into the through groove of the second electrode, namely the far end of the first electrode also falls into the through groove, therefore, the forceps can be used for conventionally clamping tissues, and can also be used for clamping tissues in a small area by utilizing the far end to realize refined operation. Furthermore, because the end part structure of the electrode is small, the contact surface of the electrode to tissues is small, and the parallel end part can carry out point contact hemostasis on a tiny bleeding part, so that the convenience and the refinement degree of the instrument operation are improved. When the handle assembly controls the first electrode and the second electrode to be separated and close to each other, the handle assembly can be stably held when the electrodes are operated, and the electrocoagulation-electrosection or point contact hemostasis operation is conveniently and accurately carried out.
The flush plane of first electrode and second electrode is perpendicular to extending direction, when carrying out point contact hemostasis operation, directly send out the electrode along the extending direction of electrode can, need not to adjust the direction of stretching out of electrode according to the inclination of flush plane, improved the hemostatic accuracy nature of point contact.
The first electric insulating layer is arranged, when the first electrode and the second electrode are close to each other, the first electric insulating layer can effectively separate the first electrode and the second electrode, and the two electrodes can be kept in an insulating state due to obstruction.
When the electrode is close to and clamps the tissue, the elastic electric insulation layer is stressed to deform, the area of the clamping acting force is increased, on one hand, the pressure applied to the electrode and the tissue is reduced, and the stress concentration is avoided; on the other hand, the elastic point insulating layer deforms, so that friction force is increased, clamped tissues are not easy to slide, and clamping stability is improved.
Other insulating objects are not arranged between the first electrode and the second electrode, and insulation is formed through an air gap, so that the number of parts arranged at the electrode part can be reduced, and the electrocoagulation and electrosection are convenient to carry out more accurately. There is no barrier between the first electrode and the second electrode, so the size of the insulation gap can be freely adjusted, and the method has better applicability.
The contact area of the clamping part of the first electrode and the tissue is smaller than that of the clamping part of the second electrode. When the electrocoagulation-electric cutting clamp component clamps the tissue, the clamping part of the first electrode and the tissue contact part generate plasma, and the tissue can be cut.
The through groove on the second electrode is matched with the wedge-shaped first electrode to be clamped, and the groove edge of the through groove is provided with teeth, so that the clamping stability is further improved.
A sliding limiting block is arranged between the first electrode and the second electrode and used for enabling the first electrode and the second electrode not to slide and dislocate and keeping the electrodes level.
The operator controls the operation assembly to drive the movable assembly to move, so that the connecting rod is driven by the movable assembly to move relative to the hard tube, and the first electrode and the second electrode are driven to perform telescopic clamping action: when the connecting rods move and retract into the hard tube, the opening range between the two connecting rods is extruded due to the limiting effect of the hard tube, so that the first electrode and the second electrode are close to and clamp the tissue to be treated; when the connecting rod extends out of the hard tube, the connecting rod is separated from the limit of the hard tube and is opened, and the first electrode and the second electrode are separated, so that the clamping of tissues can be released.
The spring makes the connecting rod move to the direction of retracting in the hard tube, so that the first electrode and the second electrode are in a joint clamping state when being naturally placed, external force is not required to be applied to maintain, and clamping is more stable and firm.
The insulating layer is arranged on the connecting rod, so that the phenomenon that other structures or human tissues contact the connecting rod in the operation process to cause current short circuit and the electric coagulation and electrotomy work cannot be normally carried out is avoided.
The U-shaped handle is arranged to be connected with the front sleeve and the rear sleeve respectively, and the relative position between the connecting rod and the hard tube can be adjusted by changing the force when the U-shaped handle is held, namely the clamping loosening state between the first electrode and the second electrode. When the instrument is operated, the operator always keeps the holding state of the U-shaped grip, and the instrument is prevented from sliding due to unstable holding state.
The front sleeve connects the hard tube and one end of the U-shaped handle, the back sleeve connects the other end of the U-shaped handle and the catheter, and the spring connects the front sleeve and the back sleeve. Through the arrangement of the front sleeve and the rear sleeve, the hard tube, the connecting rod and other components can be better adapted, and the stability of the instrument structure is improved.

In other embodiments, the rigid tube 32 may be other structurally strong metal or plastic tubes.
The handle assembly comprises a fixed assembly, a movable assembly and an operating assembly; the fixing assembly includes a hard tube 32 sleeved outside the electrode assembly to limit an opening angle between the first electrode and the second electrode; the movable assembly is simultaneously connected with the connecting rod 2 of the first electrode 11 and the connecting rod 2 of the second electrode 12; the operating assembly is simultaneously connected with the fixed assembly and the movable assembly.

In the initial state of the electrocoagulation cutting forceps provided by the embodiment, the spring 43 pushes the front sleeve 41 and the rear sleeve 42 to be away until the rear sleeve 42 is resisted by the limiting block 411 and cannot move continuously. When the rear sleeve 42 moves, the connecting rod 2 is driven to retract into the rigid tube 32, the connecting rod 2 of the first electrode 11 and the connecting rod 2 of the second electrode 12 approach under the guidance of the rigid tube 32, and the first electrode 11 and the second electrode 12 are folded to be in a clamping state.
