Description

Technical Field

[0001] The present invention relates to the technical field of pyeloscope training model instruments, and particularly relates to a simulation device for training the operation of a flexible pyeloscope for the urinary system. Background Art

[0002] Urinary calculi are one of the common diseases in urology. With the development and popularization of flexible ureteroscope and holmium laser technology, flexible ureteroscopic lithotripsy has become the preferred method for treating upper urinary tract calculi with a diameter < 2 cm. However, the operation of the flexible ureteroscope is difficult, and the endoscope body is delicate and vulnerable, which restricts the clinical promotion of the flexible ureteroscope technology. Therefore, the operation training of the flexible ureteroscope is particularly important. At present, the training modes of the flexible ureteroscope technology mainly include dry simulator and live animal surgery. For the operation training of the flexible ureteroscope that requires a large amount of training, the method of live animal surgery is too cruel. And most of the current dry simulators are relatively simple models, with insufficient simulation of the urinary system, so that the trainees cannot obtain a relatively real sense, and thus the training effect is poor. Summary of the Invention

[0003] In view of the defects that the current pyeloscope operation training uses a virtual model, which cannot simulate the touch of real operation, and the use of a physical model has insufficient simulation authenticity and poor training effect in the above background art, a technical solution for a simulation device for training the operation of a flexible pyeloscope for the urinary system is provided.

[0004] It includes a lower torso model of the human body. Two opening and closing components are arranged on the front end surface of the lower torso model of the human body. A urinary system model is arranged in the inner cavity of the lower torso model of the human body. A flexible pyeloscope instrument is arranged at the rear side of the lower torso model of the human body. The lower torso model of the human body includes a silica gel bottom shell and a silica gel top shell. A soft mirror probe inlet is arranged at the pubic bone position of the silica gel top shell. The flexible pyeloscope instrument includes a pyeloscope handle and a probe catheter fixed at the front end of the pyeloscope handle. The urinary system model includes a pair of SBS kidney models embedded and fixed in the inner cavity of the silica gel bottom shell, a vein model and an artery model embedded and fixed at the central position in the inner cavity of the silica gel bottom shell. An SBS ureteral duct extending backward is connected to the inner surface of the SBS kidney model. A silica gel bladder model is connected to the rear end of the SBS ureteral duct. An SBS urethra model passing through the soft mirror probe inlet is connected to the rear side position at the top of the silica gel bladder model. Specific description: Inject artificial body fluid along the SBS urethra model into the silica gel bladder model and the SBS ureteral duct, so that the SBS urethra model, the silica gel bladder model and the SBS ureteral duct are in a slightly expanded state.
