Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an anti-fog laparoscope. Background Art

[0002] A laparoscope is a medical device with a miniature camera. It uses digital camera technology to transmit the image information captured by the laparoscope lens to the signal processing system through optical fibers and display it on a monitor to assist doctors in operating surgical instruments and conducting internal abdominal examinations. A cold light source is used to provide lighting, and the laparoscope lens is inserted into the abdominal cavity. Digital camera technology is used to transmit the image captured by the laparoscope lens to the signal processing system through optical fibers and display it on a monitor to assist doctors in operating surgical instruments and conducting internal abdominal examinations.

[0003] Laparoscopic surgery is a minimally invasive surgical method currently widely used in clinical practice. Due to its advantages such as less trauma, faster recovery and fewer complications, laparoscopic surgery is increasingly favored by surgeons. However, during laparoscopic surgery, due to tissue heating and water vapor condensation in the abdominal cavity, the mirror surface of the laparoscope is prone to fogging, which seriously affects the clarity of the surgical field of view and brings risks to the operation. Therefore, we propose an anti-fog laparoscope to solve the above problem. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fog-proof laparoscope comprises a lens barrel, the outer surface of which is fixedly connected to a heating wire, the outer surface of which is fixedly connected to an anti-fog coating, the upper surface of which is fixedly connected to a lens body, the left side of which is fixedly connected to a cold light connector, the right side of which is fixedly connected to a connector, and the inner wall of which is fixedly connected to a temperature sensor.

[0007] In a further embodiment, a handle is fixedly connected to the upper surface of the mirror body, and an outer surface of the handle is provided with anti-slip grooves.

[0008] In a further embodiment, a sealing gasket is fixedly connected to the upper surface of the handle, and the sealing gasket is made of rubber.

[0009] In a further embodiment, a protective sleeve is fixedly connected to the bottom surface of the mirror body.

[0010] In a further embodiment, a label is provided on the back of the mirror body, and the front side of the label is fixedly connected to the back side of the mirror body.

[0011] In a further embodiment, an adjusting wheel is fixedly embedded on the front side of the mirror body, and the adjusting wheel is electrically connected to the heating wire through a wire.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This device can form a uniform thin film on the surface of the lens barrel through the anti-fog coating. At the same time, the heating power of the heating wire can be adjusted through the adjustment wheel to eliminate the fogging phenomenon as soon as possible to ensure a clear surgical field of view. A clear surgical field of view helps doctors to better observe the surgical site and improve the accuracy and success rate of the operation. At the same time, a clear surgical field of view helps doctors to find the diseased tissue faster and improve the efficiency of the operation, thereby reducing the operation time and greatly reducing the risks brought by the operation. It is very practical. BRIEF DESCRIPTION OF THE DRAWINGS
