Description

Technical Field

[0001] The utility model relates to the technical field of surgery, in particular to a surgery auxiliary device. Background Art

[0002] Choledochoscopes can be divided into rigid choledochoscopes and flexible choledochoscopes, the latter of which can be further divided into fiber choledochoscopes, electronic choledochoscopes, and choledochoscopes. Choledochoscopes are mainly used for endoscopic examination of the hepatobiliary ducts and endoscopic surgery, and play a good auxiliary role in minimally invasive surgery.

[0003] After searching, the utility model with the announcement number CN219207217U discloses a choledochoscope surgical auxiliary device, which relates to the field of choledochoscope surgery. The utility model uses a transparent flexible tube set in advance, so that the choledochoscope can observe the patient's site in the flexible tube, and the flexible tube can be moved by surgical forceps to change the observation position of the choledochoscope, avoiding direct contact between the surgical forceps and the choledochoscope, and by setting a steel ring fixing part, the inner diameter of the channel for placing the choledochoscope inside it will not change, preventing the flexible tube from squeezing the choledochoscope during the bending process; when the flexible tube needs to be returned to the right position, the flexible tube is returned to the right position by pulling the pull ring, which is convenient for the doctor to return the flexible tube when the choledochoscope body cannot be observed. The returned flexible tube facilitates the doctor to remove the auxiliary device and the choledochoscope after the operation, and prevents the curved device from scraping other parts of the patient's body when it is taken out.

[0004] There are still some shortcomings in the actual use of this device:

[0005] 1. Although the flexible tube in the device is transparent, a steel ring fixing is provided inside the flexible tube. The use of the steel ring fixing is likely to affect the observation and use of the choledochoscope, resulting in obstruction of the visual field and affecting the surgical process.

[0006] 2. Although the device can return the flexible tube to its original position, when the flexible tube is in use, it cannot be pulled from multiple directions when entering the human body so that the flexible tube can enter the human body more smoothly. Utility Model Content
