Description

technical field [0001] The invention relates to a puncture cone assembly of a disposable puncture device, which is a laparoscopic matching surgical instrument suitable for establishing a working channel for abdominal surgery during laparoscopic examination and operation. Background technique [0002] At present, the puncture cone of the disposable puncture device usually does not have a blade. During abdominal surgery, a small incision is first made in the patient's abdominal soft tissue, and then the olecranon-shaped puncture cone at the front end of the puncture cone of the disposable puncture device is inserted into the small incision in the patient's abdominal soft tissue. In the middle, as the puncture cone pierces the lower layer of soft tissue, it enters the soft tissue with the tapered oblique surface at the lower part of the puncture sleeve, and the puncture cone passes through the patient's abdominal soft tissue until the abdominal cavity, and the puncture sleeve is...
