Technical Field
[0001] This utility model relates to the technical field of teaching materials, and more specifically, to a 3D-printed training model for renal tumor enucleation surgery in medical education. Background Technology
[0002] Kidney tumor enucleation is a surgical procedure that removes the tumor along its surgical capsule and sutures the remaining kidney tissue to preserve kidney function to the greatest extent possible while avoiding any residual tumor tissue.
[0003] Currently, medical students primarily rely on theoretical learning, virtual simulation training, and animal experiments when practicing renal tumor enucleation. There is a lack of dedicated 3D model training resources for this type of surgery. Therefore, we provide a 3D-printed training model for renal tumor enucleation in medical education. Utility Model Content

[0007] Preferably, both the connecting piece and the cover piece are made of silicone.
[0008] Preferably, the connecting piece and the cover piece are connected by screws.
[0009] Preferably, the angle adjustment mechanism includes a U-shaped frame, with a rotating shaft rotatably connected inside the U-shaped frame, a circular sleeve fixed between the two rotating shafts, and an annular track fixed inside the circular sleeve. The kidney model is rotatably connected to the annular track via a pair of uprights.
[0010] Preferably, the kidney model can also rotate within a circular track via a support pole.
[0011] Preferably, the side of the U-shaped frame is equipped with an electromagnetic block for adsorbing and fixing the rotating shaft, the side of the annular track is equipped with an electromagnetic strip for adsorbing and fixing the upright, and the side of the U-shaped frame is provided with two control components to control the switching of the electromagnetic block and the electromagnetic strip respectively.
[0012] Preferably, the control component includes a sliding sleeve fixed to the side of the U-shaped frame, a vertical plate fixed inside the sliding sleeve, a push rod slidably inserted into the top of the vertical plate, the top end of the push rod being arranged at the top of the sliding sleeve, the bottom end of the push rod being arranged at the bottom of the vertical plate, a first contact piece fixed to the middle of the push rod, a second contact piece fixed inside the sliding sleeve, the first contact piece contacting the second contact piece to supply power to the electromagnetic strip, and a spring passing through the middle of the push rod between the first contact piece and the vertical plate.

[0025] Example 1
[0026] This utility model discloses a 3D-printed training model for renal tumor enucleation surgery in medical education. (Refer to...) Figures 1 to 4 A training model for renal tumor enucleation surgery based on 3D printing for medical education includes a kidney model 1 with a cavity on its outer side; a tumor model 2 placed in the cavity, connected to the kidney model 1 by a connecting piece 3; a covering piece 4 placed on the side of the kidney model 1 and covering the tumor model 2; and an angle adjustment mechanism 5 for adjusting the angle of the kidney model 1, with the kidney model 1 placed inside the angle adjustment mechanism 5. Both the kidney model 1 and the tumor model 2 are made using 3D printing.
[0027] Specifically, both the connecting piece 3 and the cover piece 4 are made of silicone.
[0028] Specifically, the connecting piece 3 and the cover piece 4 are both connected by screws.
[0029] By placing the tumor model 2 into the cavity of the kidney model 1, and then attaching the connecting piece 3 at the gap between the tumor model 2 and the kidney model 1, and then attaching the covering piece 4 to the outside of the kidney model 1, ensuring that the covering piece 4 covers the tumor model 2, students can then use medical instruments to train on the removal of the tumor model 2 on the kidney model 1. Through this combination of kidney and tumor model, a real tumor removal surgery scenario can be simulated, allowing students to train on tumor resection in an environment close to real operation, thereby improving their surgical skills.
[0030] Example 2
[0031] This embodiment is a further optimization based on the above embodiments. The parts that are the same as those in the foregoing technical solutions will not be repeated here. Figure 1 and Figure 5 As shown, in order to better realize this utility model, the following configuration is adopted: In this embodiment, the angle adjustment mechanism 5 includes a U-shaped frame 500, a rotating shaft 501 is rotatably connected inside the U-shaped frame 500, a circular sleeve 502 is fixed between the two rotating shafts 501, and an annular track 503 is fixed inside the circular sleeve 502. The kidney model 1 is rotatably connected to the annular track 503 through a pair of uprights 504.
[0032] The kidney model 1 is set to rotate via the upright 504, which allows for multi-angle and multi-directional adjustments to the kidney model 1, increasing the difficulty of tumor resection training and simulating actual conditions.
[0033] Specifically, the kidney model 1 can also rotate within the circular track 503 via the upright 504.
[0034] Specifically, the side of the U-shaped frame 500 is equipped with an electromagnetic block for adsorbing and fixing the rotating shaft 501, and the side of the annular track 503 is equipped with an electromagnetic strip for adsorbing and fixing the upright 504. The side of the U-shaped frame 500 is provided with two control components to control the switching of the electromagnetic block and the electromagnetic strip respectively. By setting the electromagnetic block and the electromagnetic strip, the position of the kidney model 1 after adjustment can be fixed, thereby ensuring the stability of the kidney model 1 after the position changes.
[0035] Specifically, the control components include a sliding sleeve 505 fixed to the side of the U-shaped frame 500, a vertical plate fixed inside the sliding sleeve 505, a push rod 506 slidably inserted into the top of the vertical plate, the top end of the push rod 506 being arranged at the top of the sliding sleeve 505, the bottom end of the push rod 506 being arranged at the bottom of the vertical plate, a first contact piece 507 fixed in the middle of the push rod 506, a second contact piece 508 fixed inside the sliding sleeve 505, the first contact piece 507 and the second contact piece 508 contact each other to supply power to the electromagnetic strip (electromagnetic block), and a spring passing through the middle of the push rod 506 between the first contact piece 507 and the vertical plate.
[0036] By pressing down the push rod 506, the first contact 507 and the second contact 508 on the push rod 506 are separated, thereby disconnecting the circuit of the electromagnetic strip (electromagnetic block) and eliminating the attraction force. Thus, the kidney model 1 can be rotated and adjusted. When the push rod 506 is released, the spring will push the first contact 507 to contact the second contact 508, so that the electromagnetic strip (electromagnetic block) has attraction force again.
[0037] Specifically, the bottom of the U-shaped frame 500 is equipped with a rubber suction cup, which is used to attach the U-shaped frame 500 to the external plane. By setting the rubber suction cup, the stability of the U-shaped frame 500 can be increased.
