Background
Otoscope surgery is performed through a natural external auditory canal aperture, and is performed in an elongated external auditory canal, and the treatment of bleeding is an important step affecting the progress of the surgery. The basic procedures of current endoscopic otosurgery include cutting, peeling, etc., while intraoperative hemostasis is necessarily involved in surgery. Local hemostasis relies mainly on monopolar electrocoagulation in addition to anesthesiologist-controlled hypotension.
Because the bipolar electric coagulation which is needed in the current operation is mainly a traditional gun-shaped forceps or electric coagulation scissors structure, the gun-shaped forceps structure can touch the external auditory canal wall when being opened, and the operation under the otoscope can not be completed; the traditional electric coagulation scissors are fixed in structure, most points are used for stopping bleeding, and tissue grabbing hemostasis cannot be achieved.
Monopolar electrocoagulation uses only one electrode through which current enters the tissue and flows back through other parts of the body or ground, forming a broad current path; the hemostatic device is suitable for hemostasis in a large range; there is a certain risk of thermal damage, which is easy to cause the tissue to burn and damage the skin flap of the auditory canal;
bipolar electrocoagulation uses bipolar electrodes, one of which is used to deliver current and the other is used to recover current; the current flows along the path between the two electrodes to form a closed loop, so that the electrocoagulation effect is limited; the device is suitable for a scene with high requirements on hemostasis, wherein the scene needs to precisely cut or weld tissues; the current path is limited between the two electrodes, so that thermal damage to surrounding tissues is less caused; therefore, the damage degree and the influence range on adjacent tissues are small, and the method is quite safe;
therefore, the clinical otoscope operation needs miniature bipolar electric coagulation hemostatic forceps, and meanwhile, the current switch and parameter regulation of bipolar electric coagulation are completed with the assistance of a sub-table tour nurse, but in actual work, operators often meet the need of self-regulation according to the condition in the operation, so that great inconvenience is brought to the operation through the assistance of the tour nurse.
The foregoing description is provided for general background information and does not necessarily constitute prior art.
