Technical Field
The invention belongs to the technical field of medical operations, and particularly relates to a fascia dilator for a percutaneous nephroscope and application thereof.
Background
The percutaneous nephrolithotripsy stone-taking operation is a main method for treating huge and multiple calculi of kidney at present, and the operation is that under the guidance of X-ray or B-ultrasonic, a puncture needle is used for puncturing from the skin of a patient to enter a certain renal calyx of the kidney, then a guide wire is placed in the puncture needle, and then a puncture channel is expanded through the guide wire, and then a nephroscope is placed in the puncture channel for lithotripsy stone-taking. The step of expanding the channel is very important, the too shallow expansion can not reach the operation part, the too deep expansion can easily cause damage to the kidney and the great vessel, and during the expansion, the kidney is displaced, and if the puncture depth is not consistent with the expansion depth, the operation can be greatly influenced, so the control of the expansion depth is very important. Because X-ray has radiation, the patient and medical staff have certain physical injuries, and most medical units use B-ultrasonic for operation guidance at present. However, the development of the dilation tube during B-ultrasonic guidance is far from intuitive and clear as X-ray, and especially, a beginner is difficult to find the position of the dilation tube, so that accurate dilation is difficult to achieve, and the safe and smooth operation is influenced.
