[0050] Through the above specific implementation methods, the smoke exhaust laparoscope protective cover of the present invention can not only effectively protect the laparoscope from contamination and prevent the lens from fogging, but also efficiently exhaust the smoke generated during the operation from the body, thereby improving the safety and efficiency of the operation.

[0051] In one embodiment of the present invention, the main features of the cannula head include: a smoke exhaust duct, a lens anti-dropout step, a smoke exhaust duct anti-blocking step, an outer cannula mounting step, and an inner cannula mounting surface. The interlayer between the outer and inner ducts forms the smoke exhaust duct, and the lens is added within the inner duct to form a sealed space for mounting the laparoscope. The main features of the cannula seat include: an outer cannula mounting surface, a smoke exhaust ring duct, an inner cannula mounting surface, an inner cannula stop step, a toggle switch, a guide post, a switch stop end, and a clamping block. To prevent the lens from falling into the human body during installation, the lens anti-dropout step is designed on the outside. The lens is installed from the inside of the tube and then supported by the inner cannula to prevent it from loosening and falling. The entire device serves to protect the laparoscope inside. Workflow: Before surgery, the laparoscope is inserted into the protective cannula, the clamping block is tightened, and the laparoscope is secured within the protective cannula. The surgical procedure can then be performed while holding the protective cannula. There is a smoke exhaust channel on the protective sleeve. When laser cutting surgery is performed in the abdominal cavity, there will be a large amount of burning smoke. A large amount of carbon dioxide gas is introduced into the abdominal cavity at constant pressure in advance. Under positive pressure conditions, the gas will continuously pass through the smoke exhaust pipe opening, follow the pipe to the smoke exhaust ring, and enter the smoke exhaust pipe of the sleeve seat. At this time, just turn on the toggle switch and the smoke can be discharged from the body along with the gas.

[0052] In the above embodiment, the lens is mounted on the inclined surface of the lens anti-slip step inside the cannula head, providing a tight fit. Installation: Apply medical glue to the outer contour of the lens, then insert the lens from the right side of the cannula head, fitting it against the lens anti-slip step. Then, insert the inner cannula in the same direction, aligning the inclined surface of the inner cannula with the lens and pressing it firmly to prevent it from falling off in either direction.

[0053] In addition, to prevent the lens from fogging, nitrogen is injected into the cannula when the laparoscope is inserted to prevent the lens on the laparoscope from fogging.

[0054] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
