Choledochoscope sheath for removing calculi/polyps by gallbladder preservation

Abstract

The invention discloses a choledochoscope sheath for removing calculi / polyps by gallbladder preservation. The choledochoscope sheath comprises a drainage tube section I, a drainage tube section II, adrainage tube section III and a drainage tube section IV which are sequentially connected with each other from head to tail, a channel I going through the head of the sheath is arranged in the drainage tube section I, an upper balloon and a lower balloon are sequentially arranged on the outer wall of the drainage tube section I, a channel II communicated with the channel I is arranged in the drainage tube section II, a channel III and a channel IV are arranged in the channel II, one end of the channel III extends to the channel I and is communicated with the upper balloon, one end of the channel IV extends to the channel I and is communicated with the lower balloon, a channel V communicated with the channel II is arranged in the drainage tube section III, an inflatable connector I, an inflatable connector II and a water outlet connector are arranged on the outer wall of the drainage tube section III, the water outlet connector is communicated with the channel V, and a channel VI communicated with the channel V is arranged in the drainage tube section IV. After the upper balloon and the lower balloon are inflated, the upper balloon and the lower balloon generate elastic pressure ona gallbladder incision, hemostasis by compression is performed, and gallbladder bile and biliary sludge are prevented from entering an abdominal cavity.

Description

technical field [0001] The invention relates to a choledochoscope sheath, in particular to a choledochoscope sheath for preserving gallbladder and removing stones / polyps. Background technique [0002] Gallbladder stones and gallbladder polyps are common and frequently-occurring diseases in my country. Laparoscopic cholecystectomy is the traditional surgical solution for gallbladder stones and gallbladder polyps. Gallstone / polypectomy is another mainstream treatment for gallbladder stones and gallbladder polyps. [0003] At present, during the treatment of gallbladder stones and gallbladder polyps with laparoscopy and choledochoscopy, the laparoscope poking card is first inserted, and then the choledochoscope is inserted from the poking card sleeve, and the choledochoscope enters the gallbladder through the gallbladder incision for stone removal or removal Polyps, this method has many disadvantages: 1. Pneumoperitoneum needs to be established throughout the operation process,...

Problems solved by technology

[0003] At present, during the treatment of gallbladder stones and gallbladder polyps with laparoscopy and choledochoscopy, the laparoscope poking card is first inserted, and then the choledochoscope is inserted from the poking card sleeve, and the choledochoscope enters the gallbladder through the gallbladder incision for stone removal or removal Polyps, this method has many disadvantages: 1. Pneumoperitoneum needs to be established throughout the operation process, and long-term pneumoperitoneum is likely to affect the swing of the diaphragm, affecting respiration and circulation. 2. During the process of collecting gallstones and polyps by choledochoscope, a large amount of infectious bile, gravel, biliary sludge and choledochoscope flushing fluid flow into the abdominal cavity through the incision, which may easily lead to Abdominal infection, abdominal abscess, and gravel and biliary sludge after entering the abdominal cavity, it is difficult to remove, resulting in complications such as abdominal residual stones, abdominal adhesions, intestinal obstruction, internal fistula, abdominal abscess; 3. After gallbladder incision, gallbladder pressure decreases 4. After the choledochoscope enters the gallbladder through the poked outer tube, the choledochoscope is easy to bend in the abdominal cavity and gallbladder due to the lack of support of the choledochoscope body, which increases the need for choledochoscope to explore the cystic duct. 5. The outer sleeve of the poking card is made of hard plastic, and the choledochoscope is repeatedly entered and exited. The rubber of the choledochoscope body is easily scratched by poking the opening, resulting in leakage of the choledochoscope and damage to its electrical components; 5. Repeated entry and exit of the choledochoscope Gallbladder, prone to gallbladder incision bleeding
