Description

Technical Field

[0001] The utility model relates to the technical field of ear endoscopes, in particular to an ear endoscope that is convenient for two-handed operation. Background Art

[0002] Endoscopic ear surgery is currently popular due to its minimal trauma, lack of external incisions, and rapid postoperative recovery. However, one of the biggest drawbacks of endoscopic ear surgery is that the surgeon must hold the endoscope with one hand, thus limiting the operation to a single hand. This has significantly limited the scope of endoscopic ear surgery.

[0003] As shown in the announcement number CN 215383871 U, an ear endoscope that is easy to operate with both hands is disclosed. It is provided with a main body, a first tube body, a second tube body and a refraction part for refracting objects. One end of the first tube body is connected to the main body, and the other end of the first tube body is connected to the second tube body. The other end of the first tube body is a detection end. The device does not have a stable clamping and fixing mechanism, and cannot fix the ear endoscope inside the patient's ear canal, thereby freeing the hands of medical staff, enabling the surgeon to treat the patient more accurately, and greatly improving the success rate of the operation. At the same time, there is no support mechanism for adjusting the direction and height, and corresponding adjustments cannot be made according to different on-site environments, which greatly reduces the scope of application of the device. The lack of a convenient disassembly mechanism is not conducive to the later maintenance and rapid replacement of the device. Utility Model Content
