Description

Technical Field

[0001] This application relates to the technical field of medical teaching aids, and particularly to a training model for the implantation surgery of a subcutaneous implantable cardioverter defibrillator (S-ICD). Background Art

[0002] S-ICD, namely the implantation surgery of a subcutaneous implantable cardioverter defibrillator, has been widely applied globally. As of 2022, approximately 120,000 cases of S-ICD have been implanted globally. Currently, more and more domestic hospitals have started to carry out S-ICD implantation surgeries. Based on the advantages of S-ICD compared with traditional transvenous implantable ICDs, it can be predicted that S-ICD will gain more and more popularity in the future. The surgical operation of S-ICD is very different from that of traditional ICDs. The implantation of traditional ICD leads requires vascular puncture and enters the heart through the subclavian vein, while the leads of S-ICD are implanted in the subcutaneous tissue above the sternum and do not enter the heart through blood vessels. This is actually very important because it can avoid two problems of traditional ICDs: lead damage and infection. Since the lead adheres to the heart and veins, it is not easy to remove the lead. The incidence of serious complications of percutaneous lead removal is 1% - 2%, and the mortality rate is 0.1%. Secondly, for pediatric and adolescent patients, growth and development are inevitable problems, and multiple surgeries will significantly increase the risk of infection.

[0003] The implantation process of S-ICD is not actually complicated: after anesthesia, surface positioning is performed, and only 2 - 3 incisions are required, and then S-ICD can be successfully implanted. After implantation, relevant parameters are optimized through programming, and after inducing ventricular fibrillation, it is tested whether S-ICD can defibrillate normally. However, currently, the models for training this type of surgical procedure on the market are not mature, and the difficult learning process prolongs the learning curve of doctors, affecting the popularization of this type of surgery.

[0004] Since the surgery involves multiple tissue layers with different materials for each layer, and the instruments need to perform treatment operations on the specified tissue layer, there is currently no suitable model for operation. To ensure the training effect, currently, S-ICD mainly uses animal trunks and conducts training on cadavers. Due to the large differences in the structures between animal trunks and humans, and at the same time, the operation has a large impact on environmental pollution, it is difficult to clean the training site and the cost is high; while practicing on cadavers, repeated operations are not possible, affecting the development of training. Utility Model Content

[0005] In order to provide a highly simulated and cost - controllable S-ICD surgical training device for doctors, this application provides a training model for the implantation surgery of a subcutaneous implantable cardioverter defibrillator.

[0006] The training model for the implantation surgery of a subcutaneous implantable cardioverter defibrillator provided by this application adopts the following technical solutions:

[0007] A full subcutaneous implantable defibrillator implantation surgery training model, including a simulated human body, the simulated human body includes a simulated sternum and simulated ribs, the outside of the simulated sternum and the simulated ribs is wrapped with simulated muscle tissue, and the outside of the simulated muscle tissue is provided with simulated skin tissue. A replacement skin module is detachably installed at the position corresponding to the S-ICD implantation surgery on the simulated skin tissue.

[0008] By adopting the above technical solution, doctors can perform the operation of S-ICD surgery on the simulated human body through the replacement skin module. And when the replacement skin module is used up, it can be replaced with a new one for the next practice, so as to achieve the effect of providing a highly simulated and cost-controlled S-ICD surgery training device for doctors.

[0009] Preferably, the replacement skin module is detachably installed on the simulated skin tissue through a pasting structure.

[0013] Preferably, a first pasting part with a Velcro structure is arranged around the replacement skin module, and a second pasting part corresponding to the first pasting part is arranged on the simulated skin tissue, and the first pasting part is adhesively connected to the second pasting part.

[0014] By adopting the above technical solution, when assembling the replacement skin module, only need to align the edges of the replacement skin module and the simulated skin tissue, and then press the periphery of the replacement skin module to complete the assembly, which is simple and fast.

[0015] Preferably, it further includes a base, the simulated human body is placed on the base, and the replacement skin module is located above the simulated human body away from the base.

[0016] By adopting the above technical solution, the base is used to facilitate the handling of the simulated human body.

[0017] Preferably, a groove is opened on the side of the base adjacent to the side where the simulated human body is located.

[0018] By adopting the above technical solution, the groove can be used to facilitate the taking of the base.

[0019] Preferably, the simulated human body is covered with a protective housing, and the protective housing is provided with an opening corresponding to the replaceable skin module.

[0020] By adopting the above technical solution, the protective housing can provide a certain degree of protection for the simulated human body.

[0021] Preferably, the simulated skin tissue, the replaceable skin module, and the simulated muscle tissue are all made of silicone materials similar to human skin and muscles.

[0022] By adopting the above technical solution, the simulated skin tissue, the replaceable skin module, and the simulated muscle tissue have a high similarity to real human tissues, so as to be able to restore the operation feeling during the S-ICD surgery as much as possible.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: using the simulated human body to simulate the mechanical properties of real human tissues, so as to restore the operation feeling during the surgery as much as possible; and, using the pasting mechanism to make the replaceable skin module and the simulated skin tissue detachably connected. After a replaceable skin module is used in surgical practice, it can be removed from the simulated skin tissue and replaced with a new replaceable skin module for the next surgical practice, so as to achieve the purpose of providing a highly simulated and cost-controllable S-ICD surgery training device for doctors.

Detailed Description of the Embodiment

[0028] The following further Figures 1-3 describes the present application in detail with reference to the attached

[0029] The embodiment of the present application discloses a training model for implanting a subcutaneous implantable defibrillator.

[0030] Referring to Figure 1 、 Figure 2 and Figure 3, A training model for a fully subcutaneous implantable defibrillator implantation surgery includes a simulated human body 1 and a base 5. The simulated human body 1 is placed on the base 5 for easy movement. The simulated human body 1 includes a simulated sternum 11 and simulated ribs 12. The outer sides of the simulated sternum 11 and simulated ribs 12 are wrapped with simulated muscle tissue 13, and the outer side of the simulated muscle tissue 13 is also wrapped with simulated skin tissue 14. A replaceable skin module 2 is detachably installed at the position corresponding to the S-ICD implantation surgery on the simulated skin tissue 14. After the operation practice, a new replaceable skin module 2 can be replaced, so as to provide a training model with relatively low cost and high simulation degree for doctors.

[0031] In this embodiment, the simulated sternum 11, simulated ribs 12, simulated muscle tissue 13 and simulated skin tissue 14 are all models made by reconstructing based on CT data, and then refining the structure through modeling software and combining multiple materials for composite molding. The simulated ribs 12 and simulated sternum 11 are formed by 3D printing, and the material is high-strength white resin to ensure the simulation degree of the simulated ribs 12 and simulated sternum 11. The simulated muscle tissue 13 includes the pectoralis major muscle and the latissimus dorsi muscle, which are formed by injecting glue into a mold. Among them, the material of the pectoralis major muscle is shore 0A red high-toughness food-grade silica gel, and the latissimus dorsi muscle is shore 5A red high-toughness food-grade silica gel, so as to be able to simulate the mechanical properties of real muscle tissue. The simulated skin tissue 14 and the replaceable skin module 2 are both formed by injecting glue into a mold, and the main material is shore 0A skin-colored high-elasticity food-grade silica gel, so as to be able to simulate the mechanical properties of real skin tissue.

[0032] In order to protect the simulated skin tissue 14, the outer side of the simulated human body 1 is also covered with a protective shell 4, and in this embodiment, the protective shell 4 is made of hard resin material. The protective shell 4 is provided with an opening corresponding to the replaceable skin module 2, so that the replacement operation of the replaceable skin module 2 will not be interfered.

[0033] The replacement skin module 2 is arranged on the left side of the simulated human body 1, and the boundary of the replacement skin module 2 is from the third rib on the left side to the eighth rib on the left side, and the left and right boundaries are beyond the range of the xiphoid process and the latissimus dorsi muscle to cover the operation area in the S-ICD operation. The replacement skin module 2 is mutually bonded with the simulated skin tissue 14 through the adhesive structure 3, and can be easily disassembled and assembled without damaging the simulated skin tissue 14 as much as possible. When a replacement skin module 2 is used, the replacement skin module 2 can be removed from the simulated skin tissue 14, and a new replacement skin module 2 can be re-bonded to the simulated skin tissue 14 for the next use. In this embodiment, the adhesive structure 3 is set as a Velcro structure, and the Velcro structure includes a first adhesive portion 31 and a second adhesive portion 32, and the first adhesive portion 31 is adhesively connected to the second adhesive portion 32. A first groove 51 is provided around the replacement skin module 2 near the inner side of the simulated skin tissue 14, and a second groove 51 is provided around the simulated skin tissue 14 corresponding to the replacement skin module 2. The first adhesive portion 31 is disposed in the first groove 51, and the second adhesive portion 32 is disposed in the second groove 51. In this embodiment, the first adhesive portion 31 and the second adhesive portion 32 are both adhered to the replacement skin module 2 and the simulated skin tissue 14 by means of RTV glue or the like. When assembling the replacement skin module 2, it is only necessary to align the edges of the replacement skin module 2 and the simulated skin tissue 14, and then press the four sides of the replacement skin module 2 to complete the assembly, which is simple and quick.

[0034] A base 5 is also provided at the bottom of the simulated human body 1 away from the skin replacement module 2. The base 5 is in the shape of a rectangular plate as a whole, and the simulated human body 1 can be conveniently placed on the base 5. A groove 51 is provided on the side of the base 5 adjacent to the simulated human body 1. There are four grooves 51, which are all grooved downwards from the base 5 and are respectively located in the middle of the four peripheries of the base 5. The groove 51 acts as a hidden handle, which is convenient for relevant personnel to place and take the base 5.

[0035] The implementation principle of a fully subcutaneous implantable defibrillator implantation surgery training model in an embodiment of the present application is as follows: the simulated human body 1 of the training model is produced by extracting CT data and has a high degree of similarity to the real human body structure; and by selecting suitable materials, the mechanical properties of the simulated skin tissue 14, the replacement skin module 2 and the simulated muscle tissue 13 are similar to those of real human skin and muscles, and the operating feel during the operation can be restored as much as possible; on this basis, the replacement skin module 2 can be detachably installed on the simulated skin tissue 14 through the adhesive structure 3, so that it can be replaced after the surgical practice to facilitate use next time, and the cost is relatively low.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
