Technical Field
The utility model belongs to the technical field of the peritoneoscope, concretely relates to novel defogging of peritoneoscope camera lens device.
Background
Laparoscopic surgery is a newly developed minimally invasive method and is a necessary trend for the development of future surgical methods. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities. The traditional method of the retrolaparoendoscopic surgery is to make three small 1 cm incisions on the waist of a patient, insert a tubular working channel called trocar respectively, and carry out all the following operations through the three channels; and then special lengthened surgical instruments are used for completing the same steps as the open surgery under the television monitoring, so that the same surgical effect is achieved.
In laparoscopic surgery, a laparoscopic lens is equivalent to the 'eyes' of an operator, the laparoscopic lens can enter an abdominal cavity through a puncture hole for omnibearing observation, the 'eyes' of the operator can be always covered by a layer of fog, namely, the temperature difference exists between the abdominal cavity and the lens after the lens enters the abdominal cavity because the temperature of the laparoscopic lens is lower than that of the abdominal cavity, and hot air in the abdominal cavity forms fog on the surface of the lens quickly to enable the lens to form a fuzzy state.
