Description

Technical Field

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

[0002] In single-port laparoscopic surgery, the use of electrosurgical equipment such as high-frequency electrosurgical units is essential for the accuracy and efficiency of the surgery. However, these devices produce a large amount of smoke when working, which poses a significant problem in the closed abdominal cavity. Since the abdominal cavity is a relatively closed space, the smoke cannot dissipate naturally, which will quickly reduce the clarity of the surgical field of view and cause operational problems for doctors.

[0003] Traditionally, to address this problem, surgical teams have vented smoke and carbon dioxide from the abdominal cavity directly into the operating room through vents. However, while this approach can temporarily improve the surgical field of view, it brings a series of other problems.

[0004] First, the process of exhausting smoke and gas will interrupt the continuity of the operation, thereby increasing the overall duration of the operation. In laparoscopic surgery, the extension of time not only increases the risk to the patient, but also may reduce the success rate of the operation.

[0005] Secondly, the smoke and carbon dioxide gas discharged into the operating room pollute the operating room environment. The smoke may contain harmful chemical components and particles, which not only pose a potential health threat to patients, but also may cause long-term health effects on the staff in the operating room, especially doctors.

[0006] In addition, the emission of carbon dioxide gas may also lead to a decrease in the air quality in the operating room, further exacerbating the adverse effects on patients and doctors. Long-term exposure to such an environment may cause a series of health problems, such as respiratory diseases, eye irritation, etc.

[0007] Therefore, finding a method that can effectively remove intra-abdominal smoke without polluting the operating room environment is crucial to improving the safety and efficiency of laparoscopic surgery. This is also an important direction for the development of current medical technology. Utility Model Content

The design of the circulating smoke exhaust component fully considers the special needs of single-port laparoscopic surgery. The component can effectively extract the smoke generated during the operation from the abdominal cavity, and through filtering and purification, the clean gas is reintroduced into the abdominal cavity to form a closed-loop circulation system. In this way, not only can the clear surgical field of view be maintained, but also the pollution of the operating room environment by smoke can be avoided, and the operation time of single-port laparoscopic surgery can be significantly reduced. Because the doctor no longer needs to interrupt the surgical operation due to the smoke problem, he can focus more on the operation itself and improve the efficiency of the operation. At the same time, since the operating room is no longer polluted by smoke, the quality of the surgical environment has also been significantly improved, which is conducive to protecting the health of patients and doctors.
