Drawable needle-shaped hemostasis electrode for otorhinolaryngological department

Abstract

The invention discloses a drawable needle-shaped hemostasis electrode for the otorhinolaryngological department. The drawable needle-shaped hemostasis electrode comprises an operating handle, a metalelectrode stretching out of the initial end of the operating handle and a surgical connector which is connected with the tail end of the operating handle through a cable; the operating handle comprises a handle shell, a circuit board, an operating switch, a synchronous air valve, a suction pipe, a conveying pipe, an independent air valve and a drainage pipe; the metal electrode comprises a cutterbody part, a connecting part and a cutter head part which are connected with one another in sequence, the initial end of the cutter body part extends out of a sucking port of the initial end of the suction pipe, and the tail end of the cutter body part stretches into the initial end of the operating handle to be connected with the circuit board; the cutter head part is in a needle shape, the connecting part is in a bent arc shape, the cutter body part is in a flat shape, the included angle of 45 degrees is formed between the axial direction of the cutter head part and the axial direction of the cutter body part, needles of the cutter head part are distributed away from the cutter body part, and the length of the needles exceed the pipe radius length of the suction pipe. According to the drawable needle-shaped hemostasis electrode, precise cutting of mucosa and reducing of side injuries in an operation can be achieved, clearness of the surgical horizon is maintained, observation is facilitated, and the health of medical personnel is protected.

Description

technical field [0001] The invention relates to an electrode for surgery, in particular to an aspirationable needle-shaped hemostatic electrode for ENT, and belongs to the technical field of medical instruments. Background technique [0002] The hemostatic electrode is an accessory of medical high-frequency equipment. According to the "Medical Device Classification Catalog", it belongs to the 6825 medical high-frequency equipment category, and the management category is Class II. It is an old product widely used in clinical practice. It is matched with high-frequency surgical equipment. In various clinical surgical operations, it is used for tissue cutting, separation, blood vessel clamping, hemostasis, and tissue coagulation. [0003] The existing hemostatic electrodes used in ENT surgery generally have a sheet-like electrode tip with a relatively large size; however, ENT surgery often has a deep lesion and a narrow surgical field of view, such as surgery in the throat cavi...

Problems solved by technology

[0003] The existing hemostatic electrodes used in ENT surgery generally have a sheet-like electrode tip with a relatively large size; however, ENT surgery often has a deep lesion and a narrow surgical field of view, such as surgery in the throat cavity and surgery in the nasal cavity

Therefore, when using the existing hemostatic electrode for ENT surgery to stop bleeding in the operation cavity, the mucosal damage area is large, and a large amount of surgical smoke will be generated, which will affect the vision and hinder the operation, and a large amount of surgical smoke will also harm the health of medical staff.
