Description

Technical Field

[0002] Orthopedic surgery refers to surgery involving bones, joints, muscles, and ligaments. These surgeries can be performed in orthopedics, joint surgery, spinal surgery, and other departments to treat fractures, joint diseases, muscle and ligament injuries, bone deformities, herniated discs, or other bone-related problems.

[0003] In related technologies, when determining a treatment plan or teaching, doctors can use demonstration models to explain to patients, their families, or medical students the patient's specific condition, possible surgical plans, areas that need to be operated on or removed during surgery, etc., so that patients, their families, or medical students can understand the surgical operation process more intuitively.

[0004] The formulation of a surgical plan not only focuses on the location of the lesion, but also needs to consider its related parts. However, existing demonstration models only show the specific surgical site. For example, if surgery is required on bone tissue, only the bone tissue model is displayed, while other parts related to the surgical site are not displayed. This will obviously affect the formulation of the surgical plan or the demonstration effect is poor. Summary of the Invention

DETAILED DESCRIPTION

[0033] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0035] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0036] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and are not intended to be exclusive.

[0039] In related technologies, when determining treatment plans or teaching, doctors can use bone models to explain the patient's specific condition, possible surgical options, and the areas to be incised or removed during surgery to patients, their families, or medical students. This allows them to more intuitively understand the surgical procedures. The bone model can include an artificial bone and a mounting base, with the artificial bone mounted on the mounting base.

[0040] However, since the artificial bone is only supported by the mounting base, the bone model does not restore the scene of the artificial bone in the patient's body, resulting in that it is still difficult for the patient, the patient's family or medical students to understand the surgical operation process, making the surgical demonstration effect of the bone model poor.

[0041] To solve the above problems, an embodiment of the present application provides a surgical demonstration device. By setting up skin simulation parts, muscle simulation parts and bone simulation parts, the real scene of the bone simulation parts in the patient's body can be better restored, reducing the difficulty of understanding the surgical operation process for patients, their families or medical students, and improving the surgical demonstration effect of the surgical demonstration device.

[0042] The following will be combined Figure 1-Figure 3 The surgical demonstration device 100 provided in an embodiment of the present application is described.

[0043] See also Figure 1 and Figure 2 The embodiment of the present application provides a surgical demonstration device 100. The surgical demonstration device 100 may include a housing 110, which protects the structural components located therein. The surgical demonstration device 100 may include a bone simulator 120 (e.g., an artificial bone), a skin simulator 130, and a muscle simulator 140. By providing the skin simulator 130, the muscle simulator 140, and the bone simulator 120, the real scene of the bone simulator 120 inside the patient's body can be better restored, thereby reducing the difficulty for the patient, the patient's family members, or medical students (collectively referred to as observers) to understand the surgical operation process, and improving the surgical demonstration effect of the surgical demonstration device 100. For example, a scalpel and an endoscope can be inserted into the surgical demonstration device 100 through the skin simulator 130 and the muscle simulator 140.

[0044] For example, the skin simulation member 130 may include a silicone plate, or be formed of other elastic materials.

[0045] Exemplarily, the muscle simulation member 140 may include a foamed silicone plate, or be formed of other elastic materials.

[0046] Exemplarily, the housing 110 may be an acrylic housing, for example, a transparent acrylic housing.

[0047] For example, see Figure 1 and Figure 2The shell 110 may have a receiving cavity 114, the bone simulation part 120 may be located in the receiving cavity 114, and the shell 110 may protect the bone simulation part 120. The shell 110 may include a first shell wall 111 located on one side of the first direction A, and the first shell wall 111 may be used to fix the muscle simulation part 140 and the skin simulation part 130. The first shell wall 111 may have a first through hole 1111, and the first through hole 1111 passes through the first shell wall 111 along the first direction A, and the first through hole 1111 is connected to the receiving cavity 114 and the outside of the shell 110. The skin simulation part 130 is located on the side of the first shell wall 111 away from the receiving cavity 114, and the skin simulation part 130 covers the first through hole 1111. The muscle simulation part 140 may be located on the side of the skin simulation part 130 facing the receiving cavity 114, and the muscle simulation part 140 extends into the first through hole 1111. The first through hole 1111 can limit the muscle simulation part 140. Such a configuration enables the bone simulation part 120, muscle simulation part 140 and skin simulation part 130 to be arranged from the inside to the outside to restore the real scene of the patient's body tissue, thereby reducing the difficulty for observers to understand the operation process of the operation and improving the surgical demonstration effect of the surgical demonstration device 100.

[0048] Exemplary, participating Figure 1 The housing 110 may include a second housing wall 112 , and the second housing wall 112 and the first housing wall 111 may be opposite to each other along the first direction A and spaced apart.

[0049] Exemplary, participating Figure 1 The housing 110 may include a housing sidewall 113, which may be located between the first housing wall 111 and the second housing wall 112. The second housing wall 112 may be connected to the first housing wall 111 via the housing sidewall 113. For example, the first housing wall 111 may be a housing top wall, the second housing wall 112 may be a housing bottom wall, and the housing sidewall 113 may support the housing top wall.

[0050] For example, the orthographic projection of the housing sidewall 113 on the plane where the first housing wall 111 is located can be a polygon, such as a quadrilateral, a pentagon, etc. Taking a quadrilateral as an example, the housing sidewall 113 can include a housing front wall, a housing rear wall, a housing left wall, and a housing right wall.

[0051] For example, the orthographic projection of the shell sidewall 113 on the plane of the first shell wall 111 can be circular or elliptical. In this way, the observer can clearly observe the bone simulation component 120 through the shell sidewall 113, avoiding the sharp angle of the shell sidewall 113 that affects the observation effect.

[0052] For example, at least one of the first shell wall 111, the second shell wall 112, and the shell side wall 113 can be transparent, thereby facilitating an observer's observation of the bone simulation member 120 within the shell 110, further reducing the difficulty for the observer to understand the surgical procedure and facilitating a demonstration. For example, the first shell wall 111, the second shell wall 112, and the shell side wall 113 can all be transparent.

[0053] In one embodiment, the surgical demonstration device 100 may further include an auxiliary component 150. The auxiliary component 150 may have a second through hole 152. The auxiliary component 150 may be located on a side of the first shell wall 111 facing the accommodating cavity 114. The second through hole 152 and the first through hole 1111 may be arranged opposite each other along a first direction A. The second through hole 152 and the first through hole 1111 may be interconnected. The muscle simulator 140 may further extend into the second through hole 152. In this way, the auxiliary component 150 may limit the position of the muscle simulator 140 and increase the thickness of the muscle simulator 140 along the first direction A, thereby allowing the muscle simulator 140 to better reproduce the real scene of the patient's muscles.

[0054] In one embodiment, the inner wall of the first through hole 1111 is flush with the inner wall of the second through hole 152, the opening size of the first through hole 1111 is the same as the opening size of the second through hole 152, and the shape of the side wall of the muscle simulator 140 is adapted to the shape of the corresponding inner wall of the first through hole 1111 and the inner wall of the second through hole 152, so that the shape of the side wall of the muscle simulator 140 is relatively simple, and the shape of the inner wall of the first through hole 1111 and the inner wall of the second through hole 152 are relatively simple, thereby reducing the difficulty of preparing the muscle simulator 140, the first through hole 1111, and the second through hole 152.

[0055] In one embodiment, a portion of the auxiliary part 150 may be provided protruding from the inner wall of the first through hole 1111, and the protruding portion of the auxiliary part 150 may form a support portion. The muscle simulator 140 may include a first muscle simulation portion and a second muscle simulation portion arranged along a first direction A, the first muscle simulation portion being located between the second muscle simulation portion and the skin simulator 130, the first muscle simulation portion being located in the first through hole 1111, and the second muscle simulation portion being located in the second through hole 152. Along a cross section perpendicular to the first direction A, the cross-sectional dimensions of the first muscle simulation portion are greater than the cross-sectional dimensions of the second muscle simulation portion, and the edge of the first muscle simulation portion covers the side of the support portion facing the first shell wall 111. In this way, the size of the first muscle simulation portion is greater than the size of the second muscle simulation portion, and when the muscle simulator 140 is installed on the first shell wall 111, the support portion may support the edge of the first muscle simulation portion, which is beneficial to improving the connection stability between the muscle simulator 140 and the shell 110.

[0056] In one embodiment, see Figure 1 The surgical demonstration device 100 may further include a mounting base 180 and a first connecting member 160, with the bone simulator 120 connected to the mounting base 180 via the first connecting member 160. The mounting base 180 is disposed on the side of the second shell wall 112 facing the accommodating cavity 114, and the bone simulator 120 and the first connecting member 160 are both disposed on the side of the mounting base 180 facing away from the second shell wall 112. This facilitates observation of the bone simulator 120 through various locations of the shell sidewall 113 and reduces the difficulty of installing the bone simulator 120 and the first connecting member 160.

[0057] For example, the mounting base 180 may be formed of a transparent acrylic material.

[0058] See Figure, see Figure 3 The surgical demonstration device 100 may have a first direction A, a second direction B, and a third direction, wherein the first direction A, the second direction B, and the third direction are all different. For example, the first direction A, the second direction B, and the third direction may be perpendicular to each other. For example, the first direction A may be the thickness direction of the surgical demonstration device 100, the second direction B may be the width direction of the surgical demonstration device 100, and the third direction may be the length direction of the surgical demonstration device 100. The length, width, and thickness in the embodiments of this application are merely for convenience of description and do not imply any limitation on dimensions. For example, the width may be greater than, equal to, or less than the length.

[0059] For example, see Figure 3 The bone simulation member 120 and the first connecting member 160 are movably connected along a first direction A, thereby adjusting the height of the bone simulation member 120 relative to the mounting base 180 and enabling the first connecting member 160 to be used to mount bone simulation members 120 of different sizes. The first connecting member 160 and the mounting base 180 are movably connected along a second direction B, thereby adjusting the position of the bone simulation member 120 relative to the mounting base 180 along the second direction B.

[0060] For example, see Figure 3The surgical demonstration device 100 may include a first fixing member 170, and the bone simulation member 120 may have a first mounting hole. The first fixing member 170 may include a first abutment portion and a first plug-in portion. The first connecting member 160 may include a first extension section 161, and the first extension section 161 may be provided with a first hollow portion 1611. The first hollow portion 1611 extends along a first direction A, and the first mounting hole and the first hollow portion 1611 are arranged opposite to each other. The first plug-in portion is inserted into the first hollow portion 1611 and the first mounting hole, and the first plug-in portion can reciprocate along the first direction A in the first hollow portion 1611, so that the bone simulation member 120 is movably connected to the first connecting member 160 through the first plug-in portion. When the bone simulation part 120 is in the installed state, the first abutment portion abuts against the side of the first extension section 161 facing away from the bone simulation part 120 to fix the first extension section 161 between the bone simulation part 120 and the first abutment portion, so that the relative position between the first extension section 161 and the bone simulation part 120 is fixed.

[0061] For example, the first fixing member 170 may be a screw.

[0062] Exemplarily, the surgical demonstration device 100 may include a second fixing member, the mounting base 180 may have a second mounting hole, the second fixing member may include a second abutting portion and a second plug-in portion, the first connector 160 may include a second extension 162 connected to the first extension 161, the second extension 162 may be provided with a second hollow portion 1621, the second hollow portion 1621 may extend along a second direction B, the second mounting hole and the second hollow portion 1621 are disposed opposite each other, the second plug-in portion is inserted into the second hollow portion 1621 and the second mounting hole, and the second plug-in portion can reciprocate in the second hollow portion 1621 along the second direction B, so that the first connector 160 and the mounting base 180 are movably connected via the second plug-in portion. When the bone simulator 120 is in the installed state, the second abutting portion abuts against the side of the second extension 162 facing away from the mounting base 180, thereby fixing the second extension 162 between the mounting base 180 and the second abutting portion, thereby fixing the relative position between the second extension 162 and the mounting base 180.

[0063] For example, the second fixing member may be a screw.

[0064] In one embodiment, the muscle simulation member 140 and the inner wall of the first through hole 1111 can be bonded together, which can reduce the difficulty of connecting the muscle simulation member 140 and the inner wall of the first through hole 1111 and reduce the manufacturing cost of the surgery demonstration device 100.

[0065] In one embodiment, the muscle simulation member 140 and the inner wall of the second through hole 152 can be bonded together, which can reduce the difficulty of connecting the muscle simulation member 140 and the inner wall of the second through hole 152 and reduce the manufacturing cost of the surgery demonstration device 100.

[0066] In one embodiment, the muscle simulation component 140 and the skin simulation component 130 can be bonded together, which can reduce the difficulty of connecting the muscle simulation component 140 and the skin simulation component 130 and reduce the manufacturing cost of the surgery demonstration device 100.

[0067] In one embodiment, the skin simulation member 130 and the first shell wall 111 can be bonded together, which can reduce the difficulty of connecting the first shell wall 111 and the skin simulation member 130 and reduce the manufacturing cost of the surgery demonstration device 100.

[0068] In one embodiment, the surgical demonstration device 100 may further include a second connecting member, which is annular and can be used to fix the skin simulation member 130. The second connecting member can be located outside the shell 110 and can be arranged around the edge of the first shell wall 111. The outer edge of the skin simulation member 130 is pressed between the second connecting member and the first shell wall 111, and the second connecting member is detachably connected to the first shell wall 111. In this way, the second connecting member blocks the skin simulation member 130 at the edge, which has little impact on the demonstration of the skin simulation member 130. The skin simulation part 130 is fixed to the first shell wall 111 by the second connecting part, so that there is no need to bond the skin simulation part 130, the muscle simulation part 140 and the first shell wall 111. Since the second connecting part is detachably connected to the first shell wall 111, the skin simulation part 130, the muscle simulation part 140 and the shell 110 can be detached, thereby reducing the difficulty of replacing the skin simulation part 130 and the muscle simulation part 140, improving the reuse rate of the surgical demonstration device 100, and reducing the use cost of the surgical demonstration device 100.

[0069] In one embodiment, the color of the muscle simulation piece 140 may be red, so as to restore the color of the patient's muscles and improve the demonstration effect of the muscle simulation piece 140 .

[0070] In one embodiment, at least one of the skin simulation part 130 , the muscle simulation part 140 , and the auxiliary part 150 may be a transparent part, thereby facilitating the observer to observe the bone simulation part 120 through at least one of the skin simulation part 130 , the muscle simulation part 140 , and the auxiliary part 150 .

[0071] In one embodiment, the muscle simulation part 140 has a groove on the side facing the bone simulation part 120, and at least part of the bone simulation part 120 can extend into the groove, and the groove wall fits with the surface of the bone simulation part 120, so that the simulated bone simulation part 120 and the muscle simulation part 140 can better restore the positional relationship between the patient's bones and muscles.

[0072] In one embodiment, the side of the muscle simulation component 140 facing the bone simulation component 120 is flat, which helps to reduce the difficulty of manufacturing the muscle simulation component 140. Along the first direction A, the muscle simulation component 140 and the bone simulation component 120 are in contact or spaced apart.

[0073] In an embodiment in which there is a gap between the muscle simulation part 140 and the bone simulation part 120 along the first direction A, the difficulty of assembling the muscle simulation part 140 and the bone simulation part 120 can be reduced. For example, the bone simulation part 120 can be completely exposed outside the muscle simulation part 140, and the obstruction of the bone simulation part 120 by the muscle simulation part 140 can be reduced, so that the patient can better observe the bone simulation part 120.

[0074] In one embodiment, the surgical demonstration device 100 may include a light-emitting element, a controller, and a pressure sensor. The light-emitting element may be located in the accommodating cavity 114 and may be positioned near the bone simulator 120. When the light-emitting element is turned on, it emits light, allowing an observer to better see the bone simulator 120. The pressure sensor may be located in at least one of the muscle simulator 140 and the skin simulator 130, or the pressure sensor may be located between the muscle simulator 140 and the skin simulator 130. The controller may be electrically connected to the light-emitting element and the pressure sensor. When the pressure detected by the pressure sensor exceeds a preset pressure, for example, during a surgical demonstration, when a scalpel applies pressure to the muscle simulator 140 and / or the skin simulator 130 when cutting, causing the pressure detected by the pressure sensor to exceed the preset pressure, the controller may be configured to turn on the light-emitting element to allow an observer to better see the bone simulator 120 during the surgical demonstration. When the surgical demonstration is not in progress, the controller may be configured to turn off the light-emitting element, thereby reducing energy consumption and increasing the lifespan of the light-emitting element.
