Technical Field
The invention relates to the technical field of medical instruments, in particular to a puncture outfit for laparoscopic surgery.
Background
The laparoscopic surgery is to make a proper number of small 1cm to 2cm incisions in the waist, then insert a pneumoperitoneum needle through the incisions, switch on a carbon dioxide inflator after confirming that the puncture is successful, so that the abdomen is effectively supported, increase the operation space of a surgeon, then insert a pipeline-shaped working channel into each incision, and then operate the instrument in vivo through the pipelines.
The conventional puncture outfit generally includes a puncture tube and a puncture core for puncturing, the puncture core is inserted into the puncture tube, and after the puncture core is opened from a human body, the puncture core is withdrawn from the puncture tube, and the puncture tube is fixed to the human body, and then a surgeon inserts a surgical instrument into the human body through a channel of the puncture tube, thereby performing an effective surgical operation.
In the operation process, the puncture tube of the existing puncture outfit is longer and made of hard materials when being fixed on a human body, so that the surgical instrument touches the upper end and the lower end of the puncture tube in the swing process, the swing range of the surgical instrument is very limited, and the limitation of the operation range of a surgeon is caused; even some of the short instruments: if the lithotomy forceps are difficult to apply, only the puncture outfit can be taken out, and the lithotomy operation is carried out under the condition of gas leakage and lithotomy; and in the swing process of the surgical instrument, gaps may occur between the puncture tube and the surgical instrument and between the puncture tube and the incision, thereby causing gas leakage from the abdomen and reducing the supporting space of the abdomen, thereby affecting the operating space and the visual range of the operator, besides, if the surgical instruments in the puncture tube need to be changed during the operation, the gas in the abdomen is easy to leak from the passage of the puncture tube and the gas in the abdomen is also easy to leak out in the changing process, thereby reducing the supporting space of the abdomen, affecting the operation space and the visual range of the operator, when the gas in the abdominal cavity leaks too much, even the gas injection in the abdominal cavity needs to be wanted again, so that the doctor can have enough visual range and operation space in the operation process, the operation time is prolonged, the operation progress is slowed down, and the workload of the doctor is increased.
