[0001] The present invention relates to a surgical simulation device, and more particularly to a device for simulating endoscopic surgery of the nasal cavity, nasopharynx, nasal septum, nasal bone complex and skull base of the human body.

Background Art

[0002] Surgical residents need to train in surgical medical techniques in order to acquire surgical skills.

[0003] For this purpose, a simulation is required that enables training in a safe, controlled and standardized environment without compromising patient safety.

[0004] The purpose of the simulation is to transfer the skills acquired without endangering the patient to the operating room.

[0005] One of the problems with surgical simulations is that they must be performed on devices that accurately reproduce the human body structure as closely as possible using cadavers, animal models, or human subjects.

[0006] Currently known devices for simulating surgical operations have the disadvantages of being complex and costly to manufacture.

Summary of the Invention

Problems to be Solved by the Invention

[0007] Therefore, an object of the present invention is to provide a device for simulating surgical operations and surgical medical techniques, in which the number of components and the manufacturing method are as simple as possible.

Means for Solving the Problems

[0008] According to the simulation device of the present invention, the above-mentioned disadvantages are solved, and there are other advantages described below. <00​​A central piece with a housing, The housing is equipped with a removable partition wall that can be detachably attached to it.

[0009] Advantageously, the removable partition comprises a central wall and two elastic layers positioned on either side of the central wall.

[0010] The surgical simulation device of the present invention preferably also includes a removable piece that is detachably attached to the central portion and preferably has a central septum positioned within an orifice.

[0011] Furthermore, the surgical simulation device of the present invention may include an outer piece, for example, shaped like a nose, which is detachably attached to a removable piece.

[0012] The surgical simulation device of the present invention may also preferably include a support base for supporting the central piece, and the support base may preferably have a support arm with an option for adjusting the differences in the inclination of the model.

[0013] Advantageously, all the components of the device are made of plastic material and can be printed with a 3D printer.

[0014] The surgical simulation device of the present invention realizes a simple simulator that accurately reproduces human biological structures, particularly the human face and nose.

[0015] In particular, in the removable septum, the central wall simulates the nasal septum, and the elastic layers simulate the cartilage wall and skin / mucosa of the nasal septum, respectively, and are replaced each time they are used. [Brief explanation of the drawing]

[0016] For a better understanding of the above explanation, drawings are attached to show actual examples, which are schematic and not limiting. [Figure 1]Figure 1 is an exploded perspective view of the surgical simulation device according to the present invention. [Modes for carrying out the invention]

[0017] Figure 1 shows an exploded view of the surgical simulation device of the present invention, illustrating its components.

[0018] In particular, the illustrated embodiments show a device for endoscopic surgical simulation of the inside of the human nose, nasopharynx, nasal septum, nasal bone complex, and skull base.

[0019] This simulation device 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.

[0020] 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 comprises a housing (11) that detachably accommodates a removable partition (2) inside.

[0021] As is clear from the figure, the housing (11) is positioned on the front of the central piece (1), almost in the center.

[0022] 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 each time a simulation is performed.

[0023] The simulation device of the present invention also includes a removable piece (3) that is removably connected to the central piece (1). This removable piece (3) has a central partition wall (31) located within the orifice (32), and the central partition wall (31) is positioned at the central front portion of the removable piece (3) corresponding to the housing (1) of the central piece (1).

[0024] Furthermore, the simulation device of the present invention also includes an elastic outer piece (4) that, for example, assumes the shape of a nose. According to the illustrated embodiment, the outer piece (4) has a cylinder (41) for attachment to the removable piece (3).

[0025] The simulation device of the present invention also includes a support base (5) provided with a support arm (51) for supporting the central piece (1), and may also include an additional support (6) on which different objects can be placed for surgical medical technology training.

[0026] When using the simulation device of the present invention, a removable partition wall (2) is attached to a predetermined position of the housing (ll), and it is only necessary to replace it with a new one when the simulation is completed.

[0027] For the sake of completeness in the description as a mere example, two examples are used to show the materials that can be used in the simulation device of the present invention as follows.

[0028] Example 1 Combine polylactic acid (PLA) and acrylonitrile - butadiene - styrene (ABS) with different colors and print using FDA - compliant 3D technology.

[0029] Example 2 All the materials used are the photocurable resins of Stratasys.

[0030] The central piece (1) is made of various materials and colors according to the training or zone. a. White zone: DraftWhite (trademark) rigid material, b. Pink Zone: DraftWhite (trademark) and VeroMagenta (trademark) are hard materials with different color intensities. c. Yellow zone: DraftWhite (trademark), Ve, and VeriYellow (trademark).

[0031] In the removable bulkhead (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.

[0032] The removable piece (3) is made of DraftWhite™.

[0033] The outer piece (4) is made of ElasticoClear®, and the cylinder (41) is made of ElasticoClear® and VeroMagenta®.

[0034] The support base (5) is made of DraftWhite™ and VeriYellow™.

[0035] Although specific embodiments of the present invention have been described, it will be obvious to those skilled in the art that the simulation apparatus described is highly modifiable and can be modified in many ways, and all the details described can be replaced with technically equivalent ones without departing from the scope of protection defined by the appended claims.
