Description
Technical field
The present invention relates to a kind of choledochoscopes to protect sheath, and specifically a kind of guarantor's gallbladder takes stone/polyp to be protected with choledochoscope
Sheath.
Background technique
Cholecystolithiasis and gallbladder polyps are China's common disease and frequently-occurring disease, and Laparoscopic Cholecystectomy is treatment cholecystolithiasis
And the traditional operation scheme of gallbladder polyps, with the development of minimal invasive techniques and gradually going deep into gallbladder function understanding, laparoscope
Protecting gallbladder and taking stone/polyp art is another mainstream scheme of current treatment cholecystolithiasis and gallbladder polyps.
Currently, it is first placed in laparoscope stamp card during taking laparoscope and choledochoscopy in treatment cholecystolithiasis and gallbladder polyps,
Choledochoscope is placed in from stamp card outer tube again, choledochoscope enters in gall-bladder through gall-bladder notch take stone or excision polyp, the party
There are shortcomings for formula: it is both needed to establish pneumoperitoneum in 1. entire surgical procedures, and prolonged pneumoperitoneum is easy to influence the swing of diaphram,
Acid poisoning and ion imbalances can be occurred by influencing breathing and circulation, the absorption of great amount of carbon dioxide, and the carbon dioxide of high pressure is through vein
Reflux, or even gas embolism occurs, jeopardize patient vitals；A large amount of infectious during 2. choledochoscope takes cholecystolithiasis and polyp
Bile, rubble, gallbladder mud and choledochoscope flushing liquor flow into intraperitoneal through notch, are easy to cause abdominal cavity infection, peritoneal abscess, and rubble
And after gallbladder mud enters abdominal cavity, it is difficult to remove completely, lead to the residual stone in abdominal cavity, abdominal cavity adhesion, intestinal obstruction, internal fistula, peritoneal abscess etc. simultaneously
Send out disease；3. Gallbladder Pressure is reduced and is collapsed, and increases the difficulty that choledochoscope enters gall-bladder after gall-bladder is cut；4. choledochoscope is through stabbing
After card outer tube enters gall-bladder, since choledochoscope shank lacks support, choledochoscope is easy to be bent in abdominal cavity and gall-bladder, increase
Choledochoscope detects the difficulty of cystic duct；5. stamp card outer tube is rigid plastics, choledochoscope is passed in and out repeatedly, and choledochoscope shank rubber holds
It is easily open and scratches by stamp, choledochoscope is caused to occur leaking outside and damaging its electric elements；5. choledochoscope passes in and out gall-bladder repeatedly, it is easy
Lead to gall-bladder notch bleeding.
Summary of the invention
To solve defect existing in the prior art, the present invention provides a kind of guarantors gallbladder and stone/polyp choledochoscope is taken to protect sheath

Compared with prior art, the invention has the following advantages that
1. protecting gallbladder stone/polyp is taken to protect sheath with choledochoscope is silica gel material, avoids during choledochoscope takes stone and stab card
Damage of the housing tube wall to choledochoscope；
2. after Filled Balloon, annular groove generates elastic pressure to gall-bladder notch, has the function of hemostasis by compression, avoid taking
Gall-bladder notch bleeding in stone art；
3. after Filled Balloon, the upper sacculus portion and lower sacculus portion of sacculus generate elastic pressure to gall-bladder notch, can avoid protecting
Gallbladder takes the displacement of stone/polyp choledochoscope protection sheath；
4. after Filled Balloon, sacculus can close gall-bladder notch, avoiding infection property bile, flushing liquor, muddy stone and gallbladder
Mud etc. enters abdominal cavity；
5. can close pneumoperitoneum and laparoscope video after guarantor's gallbladder takes stone/polyp choledochoscope protection sheath to enter gall-bladder, keep away
The loss of complication and laparoscope system that long-term pneumoperitoneum generates is exempted from；
6. water outlet connector connects negative-pressure suction pipe, infectious bile, flushing liquor, muddy stone and gallbladder mud etc. can be discharged
In vitro, it reduces above-mentioned substance and enters complication caused by abdominal cavity；
It takes stone/polyp choledochoscope protection sheath that there is good supporting role to choledochoscope 7. protecting gallbladder, is easy to choledochoscope
Gall-bladder and cystic duct are detected.
The present invention can be widely popularized in fields such as medical apparatus based on the above reasons.
