Single-hole laparoscopic choledochoscope sheath tube

Abstract

The invention provides a single-hole laparoscopic choledochoscope sheath tube. The single-hole laparoscopic choledochoscope sheath tube is characterized by comprising a body part of a single-channel hard tube, wherein the upper end of the body part is connected with a head part, and the lower end of the body part is connected with a tail part; the head part is a hose, and the front end of the headpart is conical; and an inner tube cavity of the tail part is a hose, and annular valves are respectively arranged at two ends of the inner tube cavity of the tail part. The single-hole laparoscopiccholedochoscope sheath tube has the advantages of good supporting effect on a choledochoscope, prevention of damage to the choledochoscope and the like.

Description

technical field [0001] The invention relates to a laparoscopic sheath, in particular to a single-hole laparoscopic choledochoscope sheath. Background technique [0002] The gallbladder is an important digestive organ of the human body. As people pay more attention to and protect the function of the gallbladder, gallbladder stone removal surgery was born. The surgical method has gradually evolved from the traditional small right upper quadrant incision for gallbladder preservation, through laparoscopic assisted right upper quadrant gallbladder preservation, to the current complete laparoscopic gallbladder preservation. Complete laparoscopy usually adopts three-hole or two-hole channels for gallbladder preservation. Laparoscopy enters the abdominal cavity through the poking channel of the navel, and choledochoscopy enters through the poking channel in the right upper abdomen. Under direct vision of the laparoscope, the operator holds the scope in his left hand, adjusts the di...

Problems solved by technology

[0003] As people's requirements for minimally invasive techniques are getting higher and higher, single-port laparoscopic techniques are gradually applied in clinical practice, among which single-port laparoscopic cholecystectomy is the most widely carried out, but the development of single-port laparoscopic cholecystectomy is relatively slow

The main reason is that the navel incision is far away from the gallbladder, and the choledochoscope is a flexible mirror. The mirror body lacks support during the insertion through the navel channel, which leads to a long time for the choledochoscope to enter the gallbladder, and it is difficult to fix the field of view of the choledochoscope in the gallbladder. Choledochoscopic observation and treatment are difficult
