Description

This invention relates to a surgical simulation device, and more particularly to a device for simulating endoscopic surgical procedures on the inside of the human nose, nasopharynx, nasal septum, nasal bone complex, and skull base. Surgical residents require training in surgical medical techniques in order to acquire surgical skills. To achieve this, simulations are needed that enable training in a safe, controlled, and standardized environment without compromising patient safety. The purpose of the simulation is to transfer the acquired skills to the operating room without endangering the patient. One of the challenges in surgical simulation is that the simulation must be performed on a system that reproduces the human body structure as accurately as possible, whether it be a cadaver, an animal model, or a human body. Currently known surgical simulation devices suffer from the drawbacks of being complex and expensive to manufacture. For a better understanding of the above explanation, drawings are attached to show actual examples, which are schematic and not limiting. Figure 1 is an exploded perspective view of the surgical simulation device according to the present invention. Figure 1 shows an exploded view of the surgical simulation device of the present invention, illustrating its components. In particular, the illustrated embodiments demonstrate a device for endoscopic surgical simulation of the human nasal cavity, nasopharynx, nasal septum, nasal bone complex, and skull base. This simulation system is built using CAD design and 3D printing, enabling reduced manufacturing costs. It utilizes FDM (Fused Deposition Modeling) technology with thermoplastic resin materials of different colors, and can also print using photocurable resins, allowing for more realistic soft parts and the combination of hard and soft materials. The simulation apparatus of the present invention comprises a central piece (1) made of various materials and colors, depending on the exercise or zone. The central piece (11) simulates a human face and may include cavities (not shown) that simulate the frontal and maxillary sinuses, and also includes a housing (11) that detachably accommodates a removable partition (2) inside. As is clear from the diagram, the housing (11) is positioned on the front of the central piece (1), almost in the center. The removable septum (2) comprises a central wall (21) made of rigid plastic material that simulates the nasal septum, and two elastic layers (22) provided on each side of the central wall (21). These elastic layers (22) simulate the cartilage wall and skin of the nasal septum. This removable septum (2) is replaced for each simulation. The simulation apparatus of the present invention also includes a removable piece (3) that is detachably connected to the central piece (1). This removable piece (3) has a central partition (31) located within an orifice (32), and the central partition (31) is positioned in the central front portion of the removable piece (3) corresponding to the housing (1) of the central piece (1). Furthermore, the simulation apparatus of the present invention also includes an elastic outer piece (4) that, for example, takes the shape of a nose. According to the illustrated embodiment, the outer piece (4) has a cylinder (41) for attachment to a removable piece (3). The simulation apparatus of the present invention also comprises a support base (5) equipped with a support arm (51) for supporting a central piece (1), and may also include an additional support (6) on which different objects can be placed for the practice of surgical medical techniques. When using the simulation apparatus of the present invention, it is simply a matter of attaching the removable partition wall (2) to a predetermined position in the housing (11) and replacing it with a new one after the simulation is completed. For the sake of completeness and as merely an example, two examples of materials that can be used in the simulation apparatus of the present invention are shown below. Example 1 Polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) of different colors are combined and printed using FDA-approved 3D technology. Example 2 All materials used are photocurable resins from Stratasys. The central piece (1) consists of various materials and colors, depending on the exercise and zone. a. White zone: DraftWhite (trademark) rigid materials, b. Pink Zone: DraftWhite (trademark) and VeroMagenta (trademark) are hard materials with different color intensities. c. Yellow zone: DraftWhite (trademark), Ve, and VeryYellow (trademark). In the removable partition wall (2), the elastic layer (22) consists of two 0.5 mm thick components (SUP710™ and ElasticoClear™), and the central wall (21) is made of rigid plastic. The removable piece (3) is made of DraftWhite®. The outer piece (4) is made of ElasticoClear™, and the cylinder (41) is made of ElasticoClear™ and VeroMagenta™. The support base (5) is made of
