Description
Technical Field
The utility model relates to a medical treatment of wicresoft technique and surgical instruments technical field particularly, especially relate to an exempt from pneumoperitoneum haplopore peritoneoscope and cholangioscope protection sheath pipe.
Background
With the development of instruments and surgical techniques and the attention on the beauty effect of abdominal incisions, the approach gradually goes from open cholecystectomy to three-port laparoscopic cholecystectomy to the current single-port laparoscopic cholecystectomy. At present, most of pneumoperitoneum lower laparoscopic gallbladder surgery is adopted, carbon dioxide gas is injected into an abdominal cavity to fill the abdominal cavity, so that a clear visual field under a laparoscope and an operation bow and arrow of a surgical instrument are formed, but the pneumoperitoneum lower laparoscopic gallbladder resection has the following defects: 1. the pneumoperitoneum can cause the diaphragm to move upwards, influence the breathing of a patient and increase the risk and difficulty of anesthesia; 2. a large amount of carbon dioxide is absorbed into blood to form acidosis; 3. carbon dioxide enters blood through a broken great vein and can be subjected to gas embolism, so that the life of a patient is threatened. In order to avoid the above disadvantages, pneumoperitoneum-free laparoscopic cholecystectomy has been clinically developed, including the application of suspension method and pneumoperitoneum-free laparoscopic stabbing card, wherein the suspension method has great damage to abdominal wall musculature and is gradually clinically eliminated.
With the improvement of organ protection consciousness, gallbladder preservation operations appear in the last ten years, and the operation mode gradually changes from the traditional small incision gallbladder operation of the right upper abdomen to the existing complete laparoscope gallbladder preservation operation through the laparoscope-assisted small incision gallbladder preservation operation of the right upper abdomen. The gallbladder-protecting operation of the complete laparoscope adopts three-hole or double-hole channels, the laparoscope enters the abdominal cavity through the navel poking and clamping channel, and the choledochoscope enters the abdominal cavity through the right upper abdomen poking and clamping channel. Under the direct vision of the laparoscope, an operator holds the choledochoscope with the left hand, the choledochoscope enters the gallbladder at the shortest distance by adjusting the poking direction of the right upper abdomen, and the right hand operates accessories such as a stone-taking basket and the like to perform operations such as stone-taking, polyp excision, Luo-Ashi sinus incision and the like.
With the increasing requirements of people on minimally invasive technologies, the single-port laparoscopic technology is gradually applied to clinic, wherein the cholecystectomy of the single-port laparoscopic is most widely performed, but the development of the cholecystectomy of the single-port laparoscopic is slower. Mainly because the navel incision is far away from the gall-bladder, and the choledochoscope is a soft lens, the choledochoscope enters the gall-bladder for a long time due to the fact that the support of the choledochoscope body is lacked in the process of being placed in the navel channel, and the visual field of the choledochoscope is difficult to fix in the gall-bladder, so that observation and treatment of the choledochoscope are difficult.
SUMMERY OF THE UTILITY MODEL
According to the single-port laparoscope gallbladder protection operation, the distance between the navel incision and the gallbladder is far, the choledochoscope is a soft lens, the choledochoscope is short of support in the process of being placed in the choledochoscope through the navel channel, so that the time for the choledochoscope to enter the gallbladder is long, the visual field of the choledochoscope is difficult to fix in the gallbladder, and therefore the technical problem that observation and treatment of the choledochoscope are difficult is solved, and the pneumoperitoneum-free single-port laparoscope and the choledochoscope protection sheath tube are provided. The utility model discloses mainly through putting into gas or water toward the head pipeline section, its head end can form the toper structure, need not to pour into carbon dioxide into, realizes exempting from pneumoperitoneum gall-bladder operation.
