Embodiment Construction
[0021] The present invention will be further described with reference to the drawings and embodiments.
[0022] Such as figure 1 , 2 As shown, a simple learning model for percutaneous nephroscopy includes renal calyx model 3 and renal pelvis model 1. The renal calyx model contains stones 2 as needed.
[0023] Wherein, the renal calyx and renal pelvis model are integrated structure, the renal calyx model is equipped with stones, which can be used as the target puncture calyx, the renal calyx and renal pelvis model are filled with water, and the air needs to be exhausted to avoid affecting the ultrasound image quality. In this example, medical gloves were used to ligate the distal finger cuff and proximal palm side gloves to make models of renal pelvis and calyces.
[0024] A method for making a simple learning model includes the following steps:
[0025] (1) Making the substrate: prepare 300g of starch, 1500g of drinking water, mix 300g of starch and 250g of water, stir evenly to make ...

The invention discloses a simple learning model of percutaneous nephroscopic puncture and a manufacturing method thereof. The manufacturing method comprises manufacturing of renal calyx and renal pelvis models and a matrix. The manufacturing method comprises the following steps that (1) the renal calyx and renal pelvis models are manufactured; (3) the matrix is manufactured; and (3) the models areformed. The manufactured renal calyx and renal pelvis models are put in an empty container, the manufactured matrix is poured into the container to cover the models, the system is horizontally arranged in the shade and can be used for puncture learning under B-ultrasound guidance after cooling. The model is easy to manufacture and high in degree of simulation, and the learner can understand the three-dimensional relationship between the renal pelvis, the renal calyx and the stones. The B-ultrasound image of the models is close to the actual kidney image, and the learner is enabled to effectively shorten the learning curve of percutaneous nephroscope under B-ultrasound guidance by simulation of the puncture process and the three-dimensional relationship between the puncture needle and theultrasound image. The puncture needle has a clear sense of breakthrough when entering the "target calyx" in simulation training, and the learner is enabled to enhance the puncture feeling in actual operation through repeated training.
Description
Technical field [0001] The invention relates to a simple learning model for percutaneous nephroscope puncture surgery and a manufacturing method. Background technique [0002] Percutaneous nephrolithotomy (PCNL) is a modern minimally invasive technique for the treatment of urinary calculi. It is suitable for kidney stones over 2 cm or upper ureteral stones. It has the advantages of less damage and faster recovery. In recent years, with the continuous development of PCNL technology, ultra-microchannel percutaneous nephroscope technology and visual puncture technology have made PCNL further develop towards minimally invasive. Despite the rapid development of flexible ureteroscopy, it has limitations such as high cost and low stone removal efficiency. Flexible ureteroscopy and percutaneous nephroscopy are complementary to each other, and neither can completely replace each other. [0003] PNCL is a highly technically demanding operation, bleeding and infection are the two most frequ...
