A kind of multifunctional puncture expansion device for laparoscopic operation

Abstract

The invention provides a multi-functional puncture and expansion device for laparoscopic surgery. First, the stored umbrella-shaped expandable part is put into the abdominal cavity, the base and the instrument channel are outside the body, and then the traction wire is pulled by rotating the slider. The shield is opened in the body, and the open end of the umbrella-shaped expandable part of the shield is closely attached to the abdominal wall to ensure airtightness, and then carbon dioxide is injected into the gas channel to inflate the abdominal cavity, and then a laparoscope is placed into an instrument Channel, then the surgical forceps pull the hook through other instrument channels to hang on the surrounding tissue and fix it, so that the site to be operated is fully exposed in the unfolded umbrella-shaped expandable part; and then the video of the site to be operated on is fully exposed through the laparoscope The image is convenient for doctors to observe and operate, effectively saves the operation process and time, and greatly improves the operation efficiency; the overall structure of the present invention is simple, reusable, economical and practical, flexible in use, reasonable in design, compact in structure, and suitable for wide promotion.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture expansion device with an umbrella-shaped fixing hook. Background technique [0002] Minimally invasive medicine is the most cutting-edge development direction of medical technology today. Minimally invasive surgery represented by laparoscopic surgery has gradually replaced traditional laparotomy. It is an emerging technology that gradually developed in the late 20th century. Since the 1990s, laparoscopic surgery has developed rapidly and is now widely used in the treatment of various diseases in general surgery, obstetrics and urology. Traditional laparoscopic surgery usually requires 3-6 puncture holes to complete, adding more puncture holes means increasing potential complications, such as bleeding, puncture hole hernia, and visceral damage, and affects the cosmetic effect of the postoperative abdomen. How to make abdominal surgery successfully complete...

AI Technical Summary

Problems solved by technology

In single-port laparoscopic surgery, since the laparoscope and surgical instruments are concentrated in the narrow space of the patient, compared with traditional laparoscopic surgery, this surgical method is more difficult to effectively expose the surgical field; and the disappearance of the angle between the operating instruments is all It is not conducive to the traction exposure of the surgical site, which seriously affects the doctor's surgical effect, greatly reduces the doctor's surgical efficiency, and needs to be improved urgently
