Description
- This application is a divisional application of Ser. No. 14/002,739 which is a U.S. national entry of PCT application PCT/CN2012/080092.
- This invention pertains to the technical field of medical apparatus and particularly to a method for manufacturing a disposable endoscopic puncture outfit for laparoscopy operations and a puncture outfit using the method.
- The minimally invasive surgery represented by laparoscope has developed rapidly in recent years. The surgery quantity has been more than that of traditional surgery in developed countries. The minimally invasive treatment technologies characterized by minor surgery and minor wound have gradually been recognized by extensive surgeons. Casing pipe puncture outfit is a necessary apparatus to set up surgical and observation channels in laparoscopic surgery. However, the existing casing pipe has no visible function. That is, “blind placement” is adopted. The surgeons carry out the surgery all by their experience. During the puncture process, the artery blood vessels such as retroperitoneal aorta and artery blood vessels of abdominal wall cannot be seen or touched in blind placement. Therefore, it is operated inconveniently. In case of injuries, it usually results in fatal hemorrhoea and surgery incidents. Moreover, the normal tissues of visceral organs are easily injured accidentally such as vascular, intestine and bladder injuries when the casing pipe puncture outfit is inserted in the abdominal cavity. There is a hidden danger for laparoscopic surgery complications, which can hardly guarantee the surgery safety and effectiveness.
- In allusion to the above shortcomings, one of the purposes for this invention is to provide a method for manufacturing a disposable endoscopic puncture outfit for laparoscopy operations that features simple process, easy implementation, high efficiency and effectiveness.

FIG. 7 : Before puncturing, the power socket ofvideo connecting cable 6 is plugged into power socket of power supply system. One end of thevideo connecting cable 6 is connected with thecamera shooting module 1 on thepuncture needle 2 while the other end of the video connecting cable is connected to the input port ofdisplay unit 7. Thepuncture needle 2 is inserted in the said positioningpuncture casing pipe 3 to make thepuncture needle 2 match with the positioningpuncture casing pipe 3. At this moment, the dial piece on theelastic arm 51 rotates at a certain angle with axis of the joint between theelastic arm 51 and thehandle 22 under the pressure of theupper cover 34 of the positioningpuncture casing pipe 3. The clamping position ofelastic arm 51 moves out of the movement direction of theprotective rod 23 from the clampingcap 25, and then the clampingcap 25 of theprotective rod 23 can move towards one side of thehandle 22. - During puncturing, the
transparent cover 4 of thepuncture needle 2 overcomes the elastic force of thereset spring 24 and retracts in theneedle guard 21 under the resistance from the skin, then theblade 211 of theneedle guard 21 exposes. At this moment, the saidblade 211 is used to incise the skin tissues to make thepuncture needle 2 enter the tissues slowly. Under the lighting of light source, thecamera shooting module 1 can deliver the images for the real-time process of puncturing the tissues and entering the abdominal cavity to thedisplay unit 7 through the video connecting cable. The artery blood vessels such as retroperitoneal aorta and artery blood vessels of abdominal wall cannot be seen effectively. It is operated conveniently and avoids the surgery incidents, which effectively improves the safety and effectiveness of the puncture surgery. - During puncturing, the
transparent cover 4 will reset itself under the spring force of thereset spring 24 as the resistance of thetransparent cover 4 disappears. The state that thetransparent cover 4 slightly extends out of the positioning puncture casing pipe is recovered to act as a protection function. At this moment, even though the puncturing of abdominal cavity is continued due to misoperation, it can prevent theblade 211 of theneedle guard 21 from injuring the visceral organs under the function of thetransparent cover 4. This has greatly improves the safety and effectiveness of the puncture surgery. Meanwhile, the nodular andconical bulge 332 of thecasing pipe sheath 33 enters the abdominal cavity to have thecasing pipe sheath 33 firmly fixed on the abdominal wall under the combined function of contractility formed between the nodular andconical bulge 332 and the incision expansion. The gas can be delivered into the abdominal cavity by connecting the two-way valve 35 and the pneumoperitoneum apparatus so as to maintain the air pressure of abdomen during surgery. Moreover, the principal part of puncture outfit is made with high polymer material. Its disposable use can avoid cross infection and ensure the safe use. - In this embodiment, the said
transparent cover 4 is around pipe body 41 whose one end is closed. When the closingpart 42 of the said roundpipe body 41 is in a beveled shape, the tilting angle of its bevel is 20˜70 degrees. It has the functions of puncturing and protection. In other embodiments, referring toFIG. 8-9 , the closingpart 42 of the said roundpipe body 41 is in a conical or polygonal pyramid shape and can replace theblade 211 of theneedle guard 21 and be directly used for puncturing. Referring toFIG. 10 , the closingpart 42 of the said roundpipe body 41 can be set as a spherical shape. This can effectively prevent extremely easy injuries against the normal tissues of visceral organs when the puncture outfit is inserted in the abdominal cavity, avoid laparoscopic surgery complications such as vascular, intestine and bladder injuries and guarantee the surgery safety and effectiveness. - As described in the above embodiments for this invention, other puncture outfits and their manufacturing methods by the adoption of the same or similar structures are within the protective scope of this invention.
