[0002] In the medical field, extracorporeal membrane oxygenation (ECMO) is an important medical means to maintain human functions. When operating in real time, it is necessary to insert the extracorporeal circulation tube into the human heart and lungs through puncture surgery. The doctor's proficiency in puncture surgery determines the start time of the extracorporeal membrane oxygenation process. In order to improve the proficiency of puncture surgery, doctors often use simulation models for puncture practice during puncture surgery training. For example, the invention patent with patent number: CN211149895U provides a model based on ECMO and IABP puncture and implantation, specifically providing a human body model, a detachable puncture block is set on the human body model, and the puncture block is connected to the venous tube and arterial tube in the human body model to simulate the clinical environment of ECMO. Doctors can simulate puncture experiments by operating the puncture block during training. However, during the use of this human body model, since the venous and arterial tubes in the puncture block are fixed in the puncture block, the puncture block is severely damaged after repeated use, and the solution in the tube leaks out and pollutes the simulation environment, making it impossible to achieve continuous reuse, which in turn affects the teaching effect.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0022] like Figures 1 to 5 As shown, the present invention provides a puncture surgery simulation model 100, including a human body model 10 and a simulation block 20. The human body model 10 is a hollow structure, and is made of skin imitation materials such as silicone. The human body model 10 is provided with a receiving groove 110 corresponding to the simulation block 20, and there are multiple receiving grooves 110, which are arranged at different positions of the human body model 10. The simulation block 20 can be inserted into the receiving groove 110 of the part that needs puncture, so as to simulate the puncture surgery at a specific position of the human body.

[0023] like Figures 2 to 5 As shown, the simulation block 20 includes a box body 210 , a simulation component 220 disposed in the box body 210 , and a pressure cover 230 covering the box body 210 .

[0024] The box body 210 is a rectangular parallelepiped hollow box structure with an opening at the upper end. Notches 211 are provided on the two corresponding side surfaces of the box body 210. The end of the hose 222 extends to the outside of the receiving groove after passing through the notch. The pressure cover 230 is provided on the upper opening of the box body 210. An operation port 231 is provided in the middle of the pressure cover 230. Medical personnel can perform simulated puncture exercises on the simulated component 220 in the box body 210 through the operation port 231.

[0025] Specifically, the simulation component 220 includes a silicone block 221 arranged in the box body 210, a hose 222 inserted in the silicone block 221, and a simulated leather 223 covering the silicone block 221. The silicone block 221 corresponds to the inner cavity of the box body 210. A sliding groove 224 for accommodating the hose 222 is opened in the silicone block 221. The hose 222 can slidably pass through the sliding groove 224. The box body 210 is provided with clamps 225 at both ends of the sliding groove 224, and the clamps 225 are sleeved on the outside of the hose 222. When the clamp strength of the hose 222 by the clamp 225 is lowered, that is, the clamp 225 is loosened from the hose 222, the hose 222 can be pulled outward along the extension direction of the sliding groove 224, so that the part of the hose 222 originally accommodated in the sliding groove 224 is pulled out to the outside of the sliding groove 224, and at the same time, the rear part of the hose 222 is pulled into the sliding groove 224.

[0026] The simulated leather 223 covers the sliding groove 224 of the silicone block 221, so that the rubber tube 222 can be covered by the simulated leather 223. The simulated leather 223 is made of oily bionic material, and the simulated leather 223 is pressed against the silicone block 221 by the edge of the pressure cover 230. Through the pressure of the pressure cover 230, the clinical environment of subcutaneous blood vessels can be simulated.

[0027] In an embodiment not shown, the pressure cover 230 is reversibly installed at the upper end opening of the box body 210. By reversing the pressure cover 230, the function of squeezing and fixing the simulated leather 223 can be realized. It can be understood that the pressure cover 230 can be connected to the box body 210 through a hinge structure. In addition, in this embodiment, the simulated leather 223 and the pressure cover 230 are separate structures. It can be understood that the simulated leather 223 can also be detachably fixed on the pressure cover 230. In this way, when the pressure cover 230 is installed on the box body 210, the simulated leather 223 is installed in place, which is more convenient to use.

[0028] Preferably, if Figure 4As shown, the card 225 is made of elastic plastic material, and the card 225 includes a card base 226 fixed on the inner bottom wall of the box body 210, a binding arm 227 installed on the card base 226, and a card arm 228 corresponding to the binding arm 227. The card base 226 is set at the end of the sliding groove 224, and the binding arm 227 and the card arm 228 can be bent and connected to the card base 226. A plurality of card slots 229 are opened on the binding arm 227, and a card block 2281 is protruded on the card arm 228. The card block 2281 corresponds to the card slot 229, and the card slot 229 is connected along the binding groove 224. There are multiple directions of the binding arm 227. After the binding arm 227 is bent relative to the clamping arm 228, the end of the binding arm 227 can be inserted under the clamping arm 228. When the binding arm 227 is reset to the starting position by its own elasticity, the clamping groove 229 on the binding arm 227 can be sleeved on the clamping block 2281 on the clamping arm 228. Under the restriction of the clamping block 2281 on the clamping arm 228, a stable circumferential structure can be formed between the binding arm 227 and the clamping arm 228, so that the hose 222 can be tightened to prevent the hose 222 from being misplaced during the puncture test.

[0029] Preferably, if Figure 2 and Figure 5 As shown, the simulation assembly 20 also includes an extrusion assembly 240 disposed in the box body 210. The extrusion assembly 240 can push the silicone block 221 to squeeze the rubber tube 222 in the sliding groove 224, thereby adjusting the tension of the rubber tube 222 and simulating the tension of blood vessels of different age groups.

[0030] Specifically, the extrusion assembly 240 includes a push plate 241 fixedly installed in the box body 210, a push plate 242 slidably arranged on opposite sides of the silicone block 221, a rotating plate 243 rotatably arranged on one side of the push plate 242, and a gear member 244 driving the rotating plate 243 to rotate.

[0031] The abutment plate 241 is roughly arranged in the middle position of the box body 210, and the silicone block 221 is arranged on two opposite sides of the abutment plate 241. The length direction of the abutment plate 241 is arranged along the extension direction of the sliding groove 224. The silicone block 221 is fixedly installed on the abutment plate 241, and the push plate 242 can be slidably arranged between the side wall of the box body 210 and the silicone block 211, and the push plate 242 can move toward the abutment plate 241. Under the extrusion of the push plate 242 and the abutment plate 241, the groove width of the sliding groove 224 is reduced, and the rubber tube 222 buried in the sliding groove 224 is squeezed, and the elastic potential energy of the rubber tube 222 is increased, so that a blood vessel with higher elasticity can be simulated.

[0032] A rotating rod 212 is protruded on the box body 210, and a rotating plate 243 can be rotatably mounted on the rotating rod 212. The rotating rod 212 is arranged between the push plate 242 and the side wall of the box body 210. When the rotating plate 243 rotates on the rotating rod 212, the end of the rotating plate 243 can be abutted against the push plate 242 and push the push plate 242 to move in the direction of the abutting plate 241, thereby realizing a pushing effect on the silicone block 211.

[0033] The gear member 244 includes a driven gear 2441 fixedly mounted on the rotating plate 243 and a driving gear 2442 rotatably mounted on the box body 210. The driven gear 2441 is rotatably sleeved on the rotating rod 212. The driving gear 2442 and the driven gear 2441 are meshed with each other. The box body 210 is fixedly mounted with an active rod 213. The driving gear 2442 is sleeved on the active rod 213, and part of the teeth of the driving gear 2442 pass through the side wall of the box body 210 and extend to the outside of the box body 210. Before the simulated puncture is performed, the driven gear 2441 can be driven to rotate in the box body 210 by toggling the driving gear 2442, thereby driving the rotating plate 243 to rotate in the box body 210. The end of the rotating plate 243 pushes against the push plate 242, driving the push plate 242 to move toward the push plate 241, and the silicone block 221 is pressed against.

[0034] Preferably, a locking member 250 is slidably installed on the outer wall of the box body 210, and the locking member 250 corresponds to the driving gear 2442. The locking member 250 can slide along the box body 210 and be inserted between the teeth of the driving gear 2442, thereby preventing the driving gear 2442 from malfunctioning during the simulated puncture process. Specifically, a dovetail groove is opened on the outer wall of the box body 210, and the dovetail groove corresponds to the active rod 213 arranged above the active gear 2442. The main body of the locking member 250 can be slidably fitted and inserted in the dovetail groove. A locking column 251 corresponding to the active gear 2442 is convexly provided on the locking member 250, and the locking column 251 is convexly arranged toward the active gear 2442 along the dovetail groove. When the locking column 251 follows the locking member 250 to slide along the dovetail groove, the locking column 251 can be inserted into the teeth of the active gear 2442. With the help of the shape restriction of the dovetail groove, the active gear 2442 can be prevented from continuing to rotate.

[0035] The method of using the simulation model 100 for puncture surgery medical teaching of the present invention is to insert the simulation block 20 into the accommodating groove 110, and the hose 222 in the simulation block 20 extends to the outside of the human body model 10 after passing through the notch 211, and the position of the hose 222 corresponding to the sliding groove 224 is fixed by using the clamp 225, and the simulated liquid simulating blood is injected into the hose 222 through an external compression pump or other injection facilities, and the hose 222 is squeezed with the help of the squeezing component 240 to adjust the pressure of the simulated liquid in the hose 222 to simulate the blood circulation system in the human body, and the simulated skin 223 is pressed and covered on the silicone block 221 by the pressure cover 230 to simulate part of the structure of human tissue. Medical staff conducts simulated exercises of subcutaneous puncture through the operation port 231, and when the exercise is completed, the clamping arm 228 can be pressed to reduce the restraining strength of the clamp 225 on the hose 222, so that the hose 222 can be more easily moved under external traction. By traction, the punctured part of the hose 222 can be pulled out of the sliding groove 224, and the pulled part is clamped by a hemostatic forceps. At the same time, a new section of the hose 222 that has not been punctured slides into the sliding groove 224, which is convenient for a new simulation training process.

[0036] During the above-mentioned use, after each practice, the hose 222 can be pulled out through the notch 211, so that the hose 222 in the sliding groove 224 can be updated, that is, the hose 222 can be updated in real time in the sliding groove 224 as needed, ensuring the continuous use of the hose 222 and the teaching effect of the puncture surgery. The operation is simple and convenient, and it is easy to promote and use.

[0037] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
