Description

technical field [0001] The invention relates to a disposable puncture device, which is a matching surgical instrument for external laparoscopy, and is suitable for establishing a working channel for abdominal surgery during laparoscopic examination and operation. Background technique [0002] The front end of the puncture cone of the current disposable puncture device uses a relatively sharp blade, which is easy to scratch other tissues of the internal organs, causing bleeding, and causing more pain for the patient. In addition, the current puncture device is prone to air leakage during the operation, and the gas input into the abdominal cavity will leak out. The subsidence of the abdominal cavity affects the normal operation of laparoscopic surgery. Contents of the invention [0003] The object of the present invention is to provide a disposable puncture device for the above disadvantages. The puncture cone adopts the olecranon-type puncture cone, which can easily penetra...
