Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a puncture device and a puncture system. Background Art

[0002] In laparoscopic surgery, there is a problem of smoke generated by the use of electrosurgical equipment (such as high-frequency electric knife). This smoke is mainly composed of gases and particles generated when the electric knife cuts or coagulates tissue during surgery. In the closed abdominal environment, this smoke cannot dissipate naturally, so it will gather in the surgical area and cause significant interference with the surgical field of view.

[0003] The presence of smoke not only obscures the surgical field of view, but may also have other adverse effects on the surgical process. For example, particles in the smoke may adhere to the laparoscope lens, further reducing the clarity of the field of view. In addition, smoke may also contain harmful chemicals that may cause infection or other complications when they come into contact with the surgical wound.

[0004] Traditionally, to address the smoke problem, surgical teams have typically vented intra-abdominal smoke and CO2 gas directly into the operating room. However, this approach has several significant disadvantages. First, venting smoke and gas takes extra time, thus prolonging the overall duration of surgery. Second, smoke and CO2 vented into the operating room may negatively impact the air quality in the operating room, posing a potential threat to the health of patients and physicians.

[0005] In addition to the smoke problem, another problem that may occur when inserting the laparoscope into the abdominal cavity is that due to the difference between the body temperature and the temperature of the laparoscope, fog may form on the surface of the laparoscope. This fog will also interfere with the surgical field of view and affect the smooth progress of the operation. Utility Model Content
