Description

Technical Field

[0001] The utility model relates to the technical field of electrocoagulation devices, in particular to an electrocoagulation hemostasis device suitable for ear endoscopes. Background Art

[0002] The bipolar electrocoagulation device uses bipolar electrodes, one of which is used to transmit current and the other is used to recover current; the current flows along the path between the two electrodes to form a closed loop, and the electrocoagulation effect is relatively limited; it is suitable for scenarios that require precise cutting or welding of tissues and have high requirements for hemostasis; its current path is limited between the two electrodes, causing less thermal damage to surrounding tissues; therefore, the degree of damage to adjacent tissues and the scope of impact are very small, and it is quite safe.

[0003] Due to the narrow space in the ear canal, the miniaturization of the in-ear electrocoagulation hemostatic equipment has always been one of the directions to be considered. For example, the Chinese patent with publication number CN117137615A discloses a miniature ear endoscope bipolar electrocoagulation hemostatic forceps, which is used to control the movable handle to rotate around the clamp body, and then the electrocoagulation hemostatic forceps at the end of the movable tube is pushed out of the fixed tube through the linkage rod, and the extended electrocoagulation hemostatic forceps remain in an open state. The defect of this type of hemostatic forceps is that the opening direction of the hemostatic forceps is toward the axis of the fixed tube, and in the environment inside the ear, it is often the inner wall of the ear canal that needs to be clamped for hemostasis. At present, there is a lack of hemostatic devices that can achieve radial outward clamping. Utility Model Content

The L-shaped extension structure formed by the combination of the radial extension part extending radially and the axial extension part extending axially facilitates the clamping and hemostasis of the inner wall of the ear canal.

[0019] The initial shape of the shape memory alloy is an L-shaped bending structure;

[0021] When the two electrocoagulation rods are powered on, they heat up and the shape memory alloy returns to its initial L-shape. Shape memory alloys can be deformed arbitrarily at low temperatures and can be straight.

[0022] Further preferably, a hollow channel is opened in the center of the electrocoagulation rod.
