Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a surgery training simulation device and a surgery training system. Background Art

[0002] In order to improve doctors' surgical skills, preoperative training is often required to increase the success rate of the operation. At present, for laparoscopic surgery training, doctors can only use animal surgery or artificial synthetic materials. There are several situations:

[0003] (1) Using live animals for animal surgery: Animal surgery requires supporting conditions such as animal operating rooms, temporary animal feeding rooms, and anesthesia equipment. The investment in venues, personnel, and equipment is high, and the convenience is low, which makes the training cost very high. It is difficult for ordinary doctors to have the opportunity to practice extensively to meet the skill requirements of actual human surgery.

[0004] (2) Surgical training using a complete set of animal internal organs: It is necessary to use a variety of instruments to meet other indicators such as internal organ blood flow and pressure, and it is also necessary to maintain the freshness of the animal internal organs. The training cost is high, and practicing a certain surgical procedure will waste other organs. In addition, some organs are not possessed by a single animal, such as pigs do not have an appendix but rabbits do, and the pig uterus is very different from the human uterus.

[0005] (3) Surgical training using a single animal organ: The training steps are relatively simple and cannot meet the needs of human surgical operations, such as the use of energy instruments and equipment and the continuity of surgical operation steps.

[0006] (4) Use of 3D simulator: However, human tissue is a complex multi-layered tissue, and since its properties depend on the number of layers, layer thickness, orientation of muscle fibers, humidity, temperature, etc., simulation is very difficult.

[0007] (5) Use of artificial synthetic materials: Although artificial synthetic materials can simulate the structure of the human appendix, they have problems such as high cost, low realism and poor feel.

[0008] In view of this, this application is hereby filed. Summary of the invention

During the simulation process, the operation cavity 101 is used to perform surgical operations, and the perfusion cavity 102 is used to place perfusion liquid such as "blood".

[0044] Specifically, "blood" can be real blood or a dyed aqueous solution, which is not limited here.

[0045] Please combine Figure 1 and Figure 2 The shell 110 is provided with a skin simulation layer 150 for covering the operation cavity 101, and the position of the mesh plate 120 corresponds to the skin simulation layer 150, so that the surgical organ can be operated after the skin simulation layer 150 is cut open; the shell 110 is equipped with a perfusion pump 130, which has a liquid inlet and a liquid outlet for connecting to the artery of the surgical organ, and the liquid inlet of the perfusion pump 130 is connected to the perfusion cavity 102. After the skin simulation layer 150 is cut open, the surgical organ is simulated, and during the operation, the perfusion liquid in the perfusion cavity 102 is input into the artery of the surgical organ by the perfusion pump 130, the simulation operation is very realistic, and the operation can be performed on a certain isolated organ, and the operation cost is low.

[0046] In a preferred embodiment of the present invention, the housing 110 includes an upper housing 111, an inner housing 112 with an opening at the top, and a lower housing 113 with an opening at the top. The upper housing 111 covers the top wall of the lower housing 113, and the inner housing 112 is accommodated in the accommodation space formed by the upper housing 111 and the lower housing 113. The mesh plate 120 is installed in the inner housing 112 to divide the inner housing 112 into an operation cavity 101 and a perfusion cavity 102. An operation notch 114 is provided on the top wall of the upper housing 111. The skin simulation layer 150 is installed on the upper housing 111 to cover the operation notch 114, and is fixed by the internal ribs of the upper cover 107. The housing 110 is configured in the form of an upper housing 111, an inner housing 112, and a lower housing 113. The upper housing 111 and the lower housing 113 can be connected by bonding or snapping, and the top wall of the inner housing 112 and the top inner wall of the upper housing 111 can be connected by snapping, and the overall stability is good.

[0047] Specifically, the skin simulation layer 150 can be made of materials such as rubber or silicone, preferably materials close to human skin, and can be fixed by providing grooves on the wall surface around the operating notch 114 of the upper shell 111 and internal ribs of the upper cover 107 .

[0048] In a preferred embodiment of the present invention, an annular convex strip 115 for mounting the mesh plate 120 is provided on the inner wall of the inner shell 112 to divide the inner shell 112 into an operating portion 116 and a pouring portion 117. The diameter of the inner shell 112 gradually increases from the bottom end of the pouring portion 117 to the top end of the operating portion 116, and the pouring portion 117 is accommodated in the lower shell 113. The inner wall of the upper shell 111 cooperates with the top of the inner shell 112, and can be limited by a snap-fit ​​method.

[0049] Furthermore, the perfusion pump 130 is installed in the power interval 103 between the outer wall of the perfusion part 117 and the inner wall of the lower shell 113. An auxiliary pump 140 is also installed in the power interval 103. The inlet of the auxiliary pump 140 is used to be connected to at least one of the vein of the surgical organ, the external pipeline and the perfusion cavity. The outlet of the auxiliary pump 140 is connected to the artery of the surgical organ or the surgical instrument. The inlet and outlet of the auxiliary pump 140 are both arranged on the side wall of the operation cavity 101 of the inner shell 112. The auxiliary pump 140 is turned on when it is needed. If it is necessary to fill the organ quickly, the auxiliary pump 140 is connected to the artery of the surgical organ; if it is necessary to draw out the "blood" in the organ, the auxiliary pump 140 is connected to the vein of the surgical organ; if it is necessary to add liquid to the perfusion cavity 102, the auxiliary pump 140 is connected to the external liquid inlet pipeline.

[0050] It should be noted that the inlet (inlet) of the auxiliary pump 140 provides negative pressure, which can be used to attract liquid (connecting veins, external pipelines, and perfusion cavities); the outlet provides positive pressure, which can replenish liquid (connecting arteries and surgical instruments).

[0051] Specifically, please combine Figure 2 and Figure 3 The mesh plate 120 is densely arranged with downflow holes to allow the "blood" flowing out of the organ vein to flow back into the perfusion cavity 102. In some embodiments, the mesh plate 120 can be in the form of two semicircular plates, with a hinge or other rotating connector in the middle for easy storage when not in use. Square notches are provided on both semicircular plates for the pipelines of the perfusion pump 130 and the auxiliary pump 140 to pass through.

[0052] like Figure 2 As shown in the figure, a first circuit element 104 is arranged on the side wall of the upper shell 111, and a second circuit element 105 is arranged on the side wall of the inner shell 112. The first circuit element 104 includes a switch, a power jack, a banana head female socket, etc. The second circuit element 105 includes a banana head female socket element, which is convenient for the negative electrode of the electrosurgical knife to connect to the module; a quick-connect plug female socket (for the water outlet of the perfusion pump and the water inlet and outlet of the auxiliary pump) is convenient for the module or instrument to connect the perfusion pump or the auxiliary pump pipeline. One end of the electrode wire 106 is connected to the mesh plate 120, and the other end is connected to the second circuit element 105 (banana head female socket), and then connected to the first circuit element 104 through the internal circuit. Similarly, the connecting pipelines of the perfusion pump 130 and the auxiliary pump 140 are also connected to the liquid pipeline through the second circuit element 105 (quick-connect plug). The setting of its internal pipeline is referred to the prior art and will not be described in detail. The socket on the first circuit element 104 can also be connected to the electrosurgical machine for cutting practice. The female quick-connect plug on the second circuit element 105 can be quickly plugged and locked with the male quick-connect plug. The other side of the male quick-connect plug is connected to a silicone hose, which can be connected to animal organs for perfusion, or to medical equipment such as an electrosurgeoscope to provide continuous water supply. One of the three quick-connect plugs above the inner shell 112 is the water outlet of the perfusion pump 130, and the other two are the water intake (suction) of the auxiliary pump 140 and the water outlet (perfusion) of the auxiliary pump 140.

[0053] Preferably, the perfusion pump 130 is a pulse perfusion pump that can simulate the blood supply of organs such as the heart, and the auxiliary pump 140 can be a peristaltic pump. Specifically, the pulse perfusion pump is a magnetic pump that works at a certain frequency. The switch controlled by the timer on the circuit board is turned on and off at a certain frequency, thereby controlling the on and off of the power supply circuit of the pump, thereby achieving the purpose of the magnetic pump working at the same frequency. The peristaltic pump has the function of continuous perfusion and liquid suction, which can provide continuous blood and water supply for organ filling or equipment, or provide continuous suction function for organs. The pump is powered by a power adapter, and the 0-10V external control speed regulation can be achieved by adjusting the adjustable resistor, and the liquid flow can be adjusted according to actual needs.

[0054] Furthermore, a liquid outlet is provided on the perfusion part 117 of the inner shell 112, and a screen cage 160 for filtering broken tissue is installed at the liquid outlet, and the liquid inlet of the perfusion pump 130 is connected to the liquid outlet on the perfusion part 117. The screen cage 160 is used to filter the minced meat and other tissues to prevent these tissues from entering the pump body and affecting the operating life of the pump. In some embodiments, the bottom of the perfusion part 117 of the inner shell 112 and the bottom of the lower shell 113 are provided with a liquid outlet for releasing "blood" after the operation, and the plug 170 can be used to block the liquid outlet during the operation. The inner shell 112 and the lower shell 113 can be respectively provided with grooves, protrusions and other structures at the liquid outlets to cooperate and fix, which plays a further limiting role.

[0055] In some embodiments, a detachable maintenance cover 181 is further provided on the bottom wall of the lower shell 113 , and is fixed by a maintenance cover rubber pad 182 and a maintenance cover fixing plate 183 in the lower shell 113 .

[0056] Furthermore, the shell 110 also includes an upper cover 107, which is detachably connected to the top wall of the upper shell 111. The upper cover 107 can be used to protect and fix the skin simulation layer 150. It can be connected to the top wall of the upper shell 111 by a snap connection and can be removed during the simulation operation.

[0057] Furthermore, please combine Figure 1 , Figure 2 , Figure 4-6 A side opening structure 190 is also provided on the side wall of the operation cavity 101. The side opening structure 190 includes an adapter 191 for connecting a tubular organ and a side opening channel 192. The side opening channel 192 is installed on the side wall of the operation cavity 101. The adapter 191 is connected to the side opening channel 192 and is located at one end of the operation cavity 101. The adapter 191 can be of different sizes for connecting different organs, such as a 10 mm adapter for connecting the urethra, a 15 mm adapter for connecting the esophagus, a 26 mm adapter for connecting the large intestine, and a 35 mm adapter for connecting the rectum (which can also be expanded to 40 mm). The side opening channel 192 runs through the inner shell 112 and the upper shell 111, providing a port for lateral operation.

[0058] In a preferred embodiment of the present invention, the side opening structure 190 also includes a sealing cover 193 and a ball head fixing ring 194, the adapter 191 has an organ connection end 196 and a ball head fixing end 195, the ball head fixing end 195 is accommodated in the ball head fixing ring 194, the other end of the ball head fixing ring 194 is connected to the side opening channel 192, and the end of the side opening channel 192 away from the ball head fixing ring 194 is detachably connected to the sealing cover 193. Figure 4 and Figure 5The diagrams are for connections in different states. During operation, the sealing cover 193 is removed and the adapter 191 is installed in the side opening channel 192. The cylinder of the adapter 191 can point to the inside or outside of the product. The ball head is located in the spherical space formed by the side opening channel 192 and the ball head fixing ring 194 and can move freely. When the cylinder of the adapter 191 points inward, it can connect to organs such as the esophagus and large intestine; when it points outward, it can connect to the urethral corpus spongiosum, etc., to simulate an in vitro organ, etc. Specifically, adapters 191 of different sizes refer to different sizes of the organ connection end 196.

[0059] Specifically, in order to increase the sealing effect, an O-ring 197 is set between the sealing cover 193 and the side opening channel 192, and an O-ring 198 is also set between the ball head fixing ring 194 and the adapter 191. The sealing cover 193 and the side opening channel 192 are snap-connected, and the side opening channel 192 and the ball head fixing ring 194 are connected by threads.

[0060] Please refer to Figure 7 In some embodiments, a tic-tac-toe grid support 001 may be added, which is installed after being attached to the skin simulation layer 150 and placed for hanging organs to provide a stable support.

[0061] Please refer to Figure 8 and Fig. 9 In some embodiments, it also includes an organ module 002 and a liner 003 for accommodating the organ module, and the upper cover 107 is also provided with a notch 004 corresponding to the shape of the organ module. The upper cover 107 can develop shapes of other different body positions, such as the shape of the human abdomen, which can be used in conjunction with other special abdominal modules to perform surgical exercises in the abdominal area; such as the shape of the human back, which can be used in conjunction with other special back modules to perform surgical exercises in the back area; such as the shape of the human side-lying position, which can be used in conjunction with other special side-lying position modules. Similarly, the notch 004 of the upper cover 107 can provide an expansion function, where parts for hanging organs and providing support for rubber pads can be placed, and support parts for certain modules can be placed, such as an open appendectomy module.

[0062] An embodiment of the present invention further provides a surgical training system, including an operating electric knife and the above-mentioned surgical training simulation device. The operating electric knife can be connected to the socket on the above-mentioned surgical training simulation device to be powered on and perform cutting and other operations during the operation.

[0063] It should be added that electrosurgical cutting is divided into monopolar cutting and bipolar cutting, and the present invention belongs to the monopolar cutting part. Monopolar cutting uses a negative plate and an electric hook, and the high-frequency electrosurgical main unit is connected to the negative plate and the electric hook respectively. The negative plate is usually attached to the thigh or buttocks of a person during surgery.

[0064] In some embodiments, a customized wire is used with one end connected to the host and the other end connected to the banana head female socket of the first circuit element 104. The banana head female socket of the first circuit element 104 is connected to the banana head female socket of the second circuit element 105 through an internal wire. The banana head female socket of the second circuit element 105 is connected to the mesh plate 120 through the electrode wire 106.

[0065] This solution can save the cost of negative plates (negative plates can be pasted a limited number of times), can be reused, and simplifies the operation process, avoiding the use of negative plates to stick to animal modules and avoiding leading an extra electrode wire from the inside of the shell 110.

[0066] In summary, the present invention provides a surgical training simulation device, which simulates surgery on a surgical organ by placing perfusion liquid such as artificial blood in a perfusion cavity, cutting a simulated skin layer, and using a perfusion pump to input the perfusion liquid in the perfusion cavity into the artery of the surgical organ during the operation. The simulation operation is very realistic and can be performed on an isolated organ, with low operating costs.

[0067] The present invention also provides a surgical training system, including an operating electric knife and the above-mentioned surgical training simulation device, which uses part of the ex vivo organ to provide a simulated feel, and utilizes the organ's own arteriovenous pathways to perfuse "blood" to improve the authenticity of the operation.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
