Description

Technical Field

[0001] The utility model belongs to the technical field of electrocoagulation devices, and in particular relates to a side-pressure bipolar electrocoagulation device. Background Art

[0002] During the operation, medical devices such as electrocoagulation forceps can be used. During the operation, the electrocoagulation forceps are used to clamp the human tissue by opening the two claws at the front end of the forceps rod and then closing them, and electrocoagulation and hemostasis are performed through the conduction of the two electrodes. The conventional method is to drive the two claws to open or close by the axial movement of the forceps rod. Most of the existing electrocoagulation forceps have scalpel-like handles, which are operated by passing the fingers through the handles. During the long operation, the comfort is poor and it is easy to cause finger injuries to the user.

[0003] The Chinese patent publication number is: CN216021350U, and the patent name is: A comfortable and easy-to-operate electrocoagulation forceps, which belongs to the field of medical device technology. It includes a hollow gripping handle, and a gripping portion corresponding to the palm of the operator is formed on the gripping handle. An outer rod extending forward and backward is fixed on the gripping handle, and a clamp rod is movably inserted in the outer rod. An operating rod that forms a rotation support with the gripping handle is provided on the side of the gripping handle opposite to the gripping portion. The operating rod includes a forward portion corresponding to the palm side of the operator's fingers and a reverse portion corresponding to the back side of the operator's fingers. An operating space for the operator's fingers to be inserted is formed between the forward portion and the reverse portion.

[0004] Although it can meet the general usage requirements, it requires a rotating block, a fixed rod, a movable ball head, an operating rod, a connecting plate and a push rod, and the structure is relatively complex, which greatly increases the processing cost. Moreover, its function is relatively limited. It only has the function of electrocoagulation forceps and does not have the function of suction straw. Therefore, its applicability and practicality are limited. Utility Model Content

[0039] During actual application, the positive electrode wire plug is inserted into the positive pole of the electrocoagulation host, and the other end extends into the handle shell and is electrically connected to one end of the fixed straw; one end of the negative electrode wire plug is inserted into the negative pole of the electrocoagulation host, and the other end extends into the handle shell and is fixed to the movable block; at the same time, the insulating sleeve is fixedly mounted on the fixed straw, and the positive electrode head is fixed to the end of the fixed straw and is located on the outside of the end of the insulating sleeve; the insulating sleeve is mainly used to isolate the fixed straw from the negative movable tube, and the negative movable tube is movably mounted on the outside of the insulating sleeve; the connecting piece is fixed to the outer wall end of the negative movable tube and is connected to the movable block; the connecting piece and the movable block are fixed by screws.

[0040] The spring is arranged between the connecting piece and the inner wall of the handle shell; the side pressure plate is rotatably connected to the side wall of the handle shell through a pin shaft, and the inner end of the side pressure plate abuts against the side of the movable block away from the spring; the side pressure plate presses and drives the movable block to compress the spring, so that the negative electrode movable tube moves outside the insulating sleeve, and the end of the negative electrode movable tube abuts against the positive electrode head to produce electrocoagulation or electrocuting. Through the above structure, the convenience and stability of operation can be guaranteed.

[0041] At the same time, in actual application, a liquid outlet connector 13 is fixed on the outer wall of the handle shell, and the fixed straw and the insulating sleeve are both connected to the liquid outlet connector.
