Embodiment Construction

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0011] See figure 1 and figure 2 , figure 1 It is a sectional view of the anti-fog laparoscope lens provided by the present invention; figure 2 It is a cross-sectional view of the anti-fog laparoscope lens provided by the present invention.

[0012] The anti-fog laparoscope lens includes: anti-fog lens 1 , laparoscope tube 2 , partition 3 , heating wire 4 , light source conduction path 5 , image receiving path 6 and handle 7 .

[0013] The anti-fog lens 1 is connected to one end of the laparoscopic tube 2 to form a lumen, and the partition 3 is built in the middle of the lumen and connected to the inner wall of the laparoscopic tube 2 to divide the lumen into a U-shaped cavity. The heating wire 4 is arranged on one side of the U-shaped cavity, and the light source conduc...

Abstract

The embodiment of the invention discloses an antifogging laparoscope lens. The antifogging laparoscope lens comprises a holding handle, a laparoscope tube, a partitioning plate, a light source conduction path, an image receiving path, an antifogging lens and electric heating wires. The antifogging laparoscope lens is characterized in that the holding handle is connected with the external wall of the laparoscope tube, one end of the laparoscope lens is connected with the antifogging lens to form a tube cavity, the partitioning plate is internally arranged in the middle of the laparoscope tube and connected with the inner wall of the laparoscope tube, the tube cavity is divided into a U-type cavity, the electric heating wires are arranged on one side of the U-type cavity, and the light source conduction path and the image receiving path are internally arranged in the U-type cavity and face the antifogging lens. Compared with the prior art, the antifogging laparoscope lens has the advantages that the electric heating wires are arranged in the antifogging laparoscope lens, air is blown into the lens constantly during usage and heated when passing through the electric heating wires, hotair flows in the U-type cavity to heat the antifogging lens, and it is avoided that water vapor condenses on the lens since the temperature of the antifogging lens is too low, and as a result usage is affected.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anti-fog laparoscope lens. Background technique [0002] Laparoscope is a surgical instrument that uses a tiny camera to peep into the abdominal cavity and complete corresponding surgical operations. The light source provides illumination through the light source conduction channel, inserts the laparoscopic lens into the abdominal cavity through the incision of the abdominal wall, uses digital imaging technology to transmit the status of the tissues and organs in the abdominal cavity to the image processing system through the image receiving channel, and finally displays it on the monitor to assist The operator performs intra-abdominal exploration and operates surgical instruments to complete the operation. [0003] From the perspective of patient safety, the ambient temperature of the operating room is lower than the body temperature of the human body. When the l...
