ARTIFICIAL MODEL FOR SIMULATION OF PERCUTANEOUS NEPHROLITHOTOMY

摘要

The invention relates to an artificial model for practical training intended, in particular, for resident physicians and urology specialists who perform minimally-invasive surgery for removing kidney stones. According to the invention, the model consists of an artificial body (1) which partially reproduces, from the anatomical point of view, the lumbar and pelvic region of the human body, comprising two parts (A and B), i.e. an upper part and a lower part, where the upper part (A) is made of a right upper part and a left upper part (Ad and As) and the lower part (B) is made of a right lower part and a left lower part (Bd and Bs), the said upper and lower parts (Ad, As, Bd and Bs) being made of two upper front parts (Adf, Asf) and two upper back parts (Add, Asd) as well as two lower front parts (Bdf, Bsf) and two lower back parts (Bdd, Bsd), where the upper and lower parts (A and B) are provided on their inward edges with some attachment elements (2) with the role of permitting the assembling or disassembling of the artificial body (1) wherein there are some casts (a, b and c) reproducing female and male genitalia, the renal artery and vein and the ureter, and wherein some contact sensors (6) are mounted so that, in case the ureteroscope path is accidentally deviated, the said deviations are acoustically and/or visually signalled by the touched sensors, each of the right and left upper back parts being provided with a slot (3) and a recess (4) wherein there can be introduced and fixed some artificial kidneys (R) inside which there are provided various stone formations (K), the contact sensors (6) being mounted on the cast which represents the renal artery and vein and lengthwise the urethra.
