Abstract

The invention discloses an endoscope and a working method thereof. The endoscope comprises a front-end window, an inner tube, an outer tube, an optical fiber bundle, a light guide component and a heattransfer component, a space for the optical fiber bundle to pass through is formed between the inner tube and the outer tube, so that the optical fiber bundle passes through the space and reaches thefront end of the endoscope; the light guide component is used for transmitting light to the optical fiber bundle and comprises a light energy output end, and the light energy output end is arranged towards one end face of the optical fiber bundle; the heat transfer component comprises a heat absorption end and a heat output end, the heat absorption end is located near the light guide component and used for absorbing heat, and the heat output end is located near the front-end window and used for outputting the absorbed heat. The endoscope provided by the invention plays a role in heating the front-end window, the anti-fogging effect is realized, the scheme is simple in overall structure, the endoscope is convenient to disinfect and use, and potential safety hazards in the operation processare avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an endoscope and a working method thereof. Background technique [0002] At present, the development of minimally invasive surgery is becoming more and more common. When performing such operations, the endoscope is generally inserted into the cavity of the surgical object (such as the abdominal cavity) through the patient's natural orifice or a small artificial wound on the patient's body. , uterine cavity and pelvic cavity, etc.). When the endoscope is just inserted into the patient cavity, since the temperature in the patient cavity is higher than that of the endoscope, and the humidity in the cavity is also higher than that of the external environment, the outer surface of the optical window at the front end of the endoscope will A fog layer is formed due to the condensation of hot air in the patient cavity on encountering the cold endoscope front optical window. T...
