Description

Technical Field

[0001] The utility model relates to the technical field of surgical training models, in particular to a modular breast laparoscopic surgery training model. Background Art

[0002] The incidence of benign and malignant breast tumors in Chinese women has been increasing year by year. Although traditional surgery can achieve the purpose of removing tumors and saving lives, it leaves large scars on the breasts, seriously affecting the appearance of the breasts and having a great impact on the patient's physical and mental health. In addition, traditional axillary lymph node dissection causes greater trauma to the axilla, and there is a high probability of upper limb movement disorders and lymphedema after surgery.

[0003] Therefore, laparoscopic surgery has been introduced in recent years. Breast laparoscopic surgery is characterized by minimally invasive surgery, function preservation, significantly reduced intraoperative blood loss, and aesthetically pleasing appearance. However, laparoscopic breast surgery is not widely used in my country, and most large hospitals have not yet performed it. The reasons include the high technical requirements of breast laparoscopic surgery, the need for specialized training, a long learning curve, lengthy surgical preparation and operation, limitations in its application, strict indications, an unreasonable cost-effectiveness ratio, and insufficient promotion and application. Therefore, a surgical training model was introduced to provide medical staff with surgical simulation training based on planned surgical plans, thereby increasing the diversity and feasibility of surgical plans and improving surgical success rates.

[0004] Although the breast laparoscopic surgery training model in the existing technology can play a certain role in the surgical simulation training of medical staff, it still has the following defects: 1. The breast laparoscopic surgery training model in the existing technology is usually processed and formed in an integrated manner, so after some models are used by medical staff for surgical simulation training, the entire model cannot be reused, resulting in a waste of resources; 2. The lesion module cannot be adjusted and replaced, resulting in more mechanical surgical training, insufficient flexibility, and unsatisfactory surgical training results; 3. Partially damaged models cannot be maintained and replaced, the maintenance cost is high, and the service life is limited. Utility Model Content

[0036] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0037] like Figure 1-6 As shown, a modular laparoscopic breast surgery training model is used by medical personnel for simulated laparoscopic breast surgery training. The model includes a base 10, a skin module 20, a breast module 30, a muscle module 40, a blood vessel module 41, and a nerve module 42. Base 10 is molded to simulate a human upper torso. Made of soft materials such as silicone, base 10 has a texture and feel more similar to the human body.

[0038] The breast module 30, muscle module 40, vascular module 41, and nerve module 42 also simulate human organ structures and are all printed using silicone. Furthermore, the breast module 30 is made of transparent silicone, while the vascular module 41 and nerve module 42 are made of colored silicone. The colors clearly indicate the placement paths of each vascular module 41 and nerve module 42, making it easier for medical staff to quickly identify important anatomical structures during surgical simulation training, facilitating subsequent surgical exploration and surgical resection of lesion modules.

[0039] The base 10 has a cavity 101 formed within it. The cavity 101 has an opening 1011. An intracavity base 11 is removably mounted within the cavity 101 through the opening 1011. The intracavity base 11 is designed to simulate the structure of the human sternum, thereby enhancing the realistic effect of the surgical scene. Then, the breast module 30, muscle module 40, vascular module 41, and nerve module 42 are removably mounted through the opening 1011 and onto the intracavity base 11. Finally, a skin module 20 is removably mounted on the opening 1011 of the cavity 101. Several surgical ports 201 are formed in the skin module 20. Medical personnel use a laparoscope to observe the interior of the cavity 101 through these ports and perform surgical resections, biopsies, and cleanings. A hole-protecting pad 21 is positioned within the surgical port 201 to prevent wear and tear on the surgical port 201 during laparoscopic surgery.

[0040] More specifically, a fitting area 111 is provided on the intracavitary base 11, and the fitting area 111 is arranged on the surface of the intracavitary base 11. Several mounting grooves 112 are provided on the inner wall of the base 10 and roughly located at the armpit position of the model simulating the human body. The mounting grooves 112 are integrally formed with the inner wall of the base 10.

[0041] One end of the breast module 30, muscle module 40, blood vessel module 41, and nerve module 42 is provided with a fitting portion 43, which matches the surface shape and structure of the fitting area 111 of the intracavitary base 11, so that one end of the breast module 30, muscle module 40, blood vessel module 41, and nerve module 42 can be fitted and installed on the fitting area 111, and can be glued with glue if necessary. The other end of the breast module 30, muscle module 40, blood vessel module 41, and nerve module 42 is plugged into the mounting groove 112 of the base 10. In addition, rubber pads are provided between the muscle module 40, blood vessel module 41, and nerve module 42 and the base 10 and the intracavitary base 11. The provision of rubber pads can increase the tightness of the installation and prevent the modules on the base 10 and the intracavitary base 11 from loosening.

[0042] Thus, by providing a fitting area 111 on the intracavitary base 11 and providing a mounting groove 112 in the base 10, when installing the muscle module 40, the vascular module 41, and the nerve module 42, it is convenient for the fitting portion 43 at one end thereof to be fitted and connected to the fitting area 111 of the intracavitary base 11, and the other end to be inserted into the mounting groove 112 of the base 10, so that the muscle module 40, the vascular module 41, and the nerve module 42 can be conveniently and detachably installed on the intracavitary base 11 and the base 10, realizing independent installation of each module, modular installation, facilitating replacement of different modules, and adjusting the difficulty of surgical training according to surgical training needs. In addition, the fitting portion 43 can also be glued to the fitting area 111 of the base 10, further improving the installation stability of each module on the intracavitary base 11.

[0043] Moreover, the muscle module 40, blood vessel module 41 and nerve module 42 are detachably mounted on the intracavitary base 11 simulating the human sternum structure, which facilitates the installation of each surgical training module and has a high degree of simulation with the actual human body structure, which is conducive to further improving the surgical simulation training effect of medical staff.

[0044] When installing the skin module 20 on the cavity opening 1011, a protruding block 202 is provided on one side of the skin module 20, a screw hole and screw are provided on the other side of the skin module 20, and a block hole 1012 and screw hole are provided on the edge of the cavity opening 1011. Therefore, the block 202 on one side of the skin module 20 is inserted into the block hole 1012 on the edge of the cavity opening 1011, and the other side of the skin module 20 is screwed to the screw hole on the edge of the cavity opening 1011 via a screw, thereby removably fixing the skin module 20 to the cavity opening 1011 of the base 10. In addition to the above screw connection and the buckle 31 connection, magnets with opposite polarities that attract each other can also be provided on the side of the skin module 20 and the edge of the cavity opening 1011 to achieve the purpose of magnetic connection of the skin module 20 to the cavity opening 1011.

[0045] Preferably, when the breast module 30 is installed, a holder 12 is provided on the surface of the fitting area 111 of the intracavitary base 11. A breast base 303 is provided at the bottom of the breast module 30. The surface of the breast base 303 matches the surface of the bottom of the breast module 30, so that the breast base 303 can be tightly fitted to the bottom of the breast module 30. The breast module 30 and the breast base 303 are both made of transparent materials. A buckle 31 is provided on the breast base 303. Therefore, the breast module 30 is connected to the holder 12 buckle 31 by the buckle 31, and then the breast module 30 is detachably mounted on the intracavitary base 11, which is convenient for the installation and replacement of the breast module 30. By providing the breast base 303 at the bottom of the breast module 30, damage to the breast module 30 is avoided when the buckle 31 is provided and the buckle 31 is installed, thereby improving the service life of the breast module 30.

[0046] The base 12 and the buckle 31 are both made of plastic to prevent corrosion in a long-term surgical environment. The base 12 and the buckle 31 are also detachably connected so that the breast module 30 can be connected to the cavity base 11 using other detachable connection methods such as threaded connection, hinge connection, etc.

[0047] During actual surgery, the breast module 30, muscle module 40, vascular module 41, and nerve module 42 are provided with a lesion area 50 for placement of lesion modules, including but not limited to animal tumors, cysts, and lymph nodes. Lesion area 50 is placed at the junction of the muscle module 40, vascular module 41, and nerve module 42 with the axilla, or anywhere on the surface of the muscle module 40, vascular module 41, and nerve module 42, to simulate a lesion in the axilla or on the surface of the muscle module 40, vascular module 41, and nerve module 42.

[0048] Preferably, the breast module 30 has a accommodating cavity 301, which is provided with an accommodating port 3011 and a plurality of threading holes 302. The lesion module is placed in the accommodating cavity 301 through the accommodating port 3011, and the plurality of threading holes 302 are arranged around the breast module 30. Therefore, after the lesion module is placed in the accommodating cavity 301, the lesion module is connected by threading the threading holes 302, so that the lesion module can be firmly installed in the accommodating cavity 301, thereby avoiding the displacement of the lesion module in the accommodating cavity 301 during surgical simulation training, and further improving the surgical simulation training effect of medical staff. The lesion module is also arranged on the lesion area 50 in a detachable manner, which is convenient for replacing the lesion module according to the needs of surgical training, making the surgical training more targeted and diverse.

[0049] In this way, the modular breast laparoscopic surgery training model provided by the embodiment of the present application has a detachable breast module 30, a muscle module 40, a blood vessel module 41 and a nerve module 42 in the cavity 101 of the base 10, realizing a modular surgical training module setting, and a lesion area 50 for placing the lesion module is provided on each module, and medical staff can perform laparoscopic surgery in the surgical hole 201 of the skin module 20; compared with the previous surgical training model using an integrated processing and molding implementation method, the modular setting of the embodiment of the present application is convenient for medical staff to adjust and replace designated modules during surgical simulation training, such as replacing damaged modules, and configuring other modules according to surgical requirements without replacing the entire model, saving replacement costs, low maintenance costs, flexible adjustment of surgical training difficulty, and improving surgical simulation training effects.

[0050] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
