Problems solved by technology

[0002] In minimally invasive human medical operations, once a lesion is found in the human body, surgery or resection is required. During the operation, the puncture device must first be applied. In the prior art: there are reusable puncture devices made of metal materials, Its defects are: first, the design of the repeatable puncture device without a converter, and the specifications vary from thick to thin. If the puncture device needs to be replaced in surgical applications, it will cause trouble in the operation; If the disinfection is not in place, it will bring bacterial infection to the human body during the surgical treatment, and frequent disinfection is required
There is also a disposable puncture device, the defect of which is: the same design without a converter, the specifications vary from thick to thin, which also causes troubles that cannot be replaced
Moreover, pneumoperitoneum air leakage and liquid leakage are prone to occur during the operation, causing hidden dangers to the operation.
