Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a choledochoscope for minimally invasive cystic duct exploration.
Background
The gallbladder is a pear-shaped pouch located behind the liver under the right rib, i.e., the gallbladder fossa of the liver, and has the functions of concentrating and storing bile. The gallbladder is divided into four parts of bottom, body, neck and tube, and the neck is connected with the gallbladder tube. The gallbladder wall is composed of three layers of mucosa, muscle layer and adventitia.
Gallbladder protection and stone removal are used for treating common diseases of the biliary tract system, i.e. gallstone, and at first, due to the lag of medical science and technology, conservative treatment methods such as acupuncture treatment, massage treatment, medicament treatment and the like are mostly adopted; the medical field has been seeking and discussing safe and effective gallstone treatment methods with less pain and minimally invasive injury and more favorable for patients to accept for many years. The main meaning of the new concept of preserving gallbladder and removing calculus is to remove calculus and maintain the balance and physiological functions of normal human body.
The operation steps of the gallbladder-protecting calculus-removing operation mainly comprise the following steps of puncturing: the minimally invasive gallbladder-protecting lithotomy needs a laparoscope and a gallbladder-protecting endoscope, and during the operation, a laparoscopic needle is firstly inserted into the laparoscope through abdominal puncture to detect the position, the appearance and whether adhesion exists; placing a choledochoscope: after puncture, if the external part of the gallbladder is normal, a small incision of 2cm descends at the costal margin to enter the abdomen, the gallbladder is pulled, and a gallbladder protection mirror is inserted after the incision from the bottom of the gallbladder, wherein the incision is about 0.5 cm; stone taking: under the direct vision of choledochoscope, sucking bile in gallbladder with negative pressure aspirator, and washing gallbladder cavity with physiological saline for clear vision when removing calculus; confirming the presence or absence of residual calculus: the tiny calculus is not easy to be found, after the calculus removal is finished, a choledochoscope is used for repeatedly checking whether tiny calculus residues exist in the gallbladder cavity, and the condition that the bile flows into the gallbladder is observed so as to eliminate the incarceration of the calculus in the gallbladder tube; and (3) sewing: and taking out the gallstones, carefully suturing the gallbladders by using an absorbable thread in two layers after confirming that no gallstones remain, and finally suturing the operation incision layer by layer. However, the existing choledochoscope still has many defects, such as: a matched incision opening device is not used, so that the exposure and the operation of the gallbladder bottom are inconvenient, and the position change of the choledochoscope can cause wound to the abdominal wall; the outer wall of the choledochoscope is communicated with a saline water conveying pipe and a bile suction pipe, so that the choledochoscope is very difficult to rotate, the observation visual field of the choledochoscope is limited, and the choledochoscope is not flexible to use.
