[0060] The technical scheme of the utility model discloses a surgery demonstration device, which comprises a box assembly 100, a support assembly 200, a rotating shaft assembly 300 and a locking assembly 400, the box assembly 100 is internally provided with a containing cavity 101, the support assembly 200 is located in the containing cavity 101 and is used for fixing simulated tissues, a surgical instrument is inserted into the interior of the containing cavity 101 through the simulated channel 102 arranged on the top wall 110 of the box assembly 100 to perform simulated surgery on the simulated tissues, at least one side wall of the box assembly 100 is transparent, so that an observer can see the demonstration content from the side. The rotating shaft assembly 300 is rotationally connected with the box assembly 100, and the support assembly 200 arranged on the rotating shaft assembly 300 can rotate synchronously with the rotating shaft assembly 300. The locking assembly 400 is connected with the rotating shaft assembly 300 and is used for locking the rotating shaft assembly 300 to make the rotating shaft assembly 300 in a locked state or releasing the rotating shaft assembly 300 to make the rotating shaft assembly 300 in a released state, in the released state, the rotating shaft assembly 300 can rotate relative to the box assembly 100 to adjust the orientation of the simulated tissues, and in the locked state, the rotating shaft assembly 300 is fixed on the box assembly 100 to fix the orientation of the simulated tissues and ensure the stability of the simulated tissues during simulated surgery operation. Through the rotation of the rotating shaft assembly 300 in the released state, the orientation of the simulated tissues is adjusted, so that the user can perform simulated surgery operation from different angles and simulate different approaches such as posterior approach and lateral approach, more simulated surgery requirements are met, and the use flexibility of the surgery demonstration device is improved.

[0061] The locking assembly 400 can release and lock the rotating shaft assembly 300 by using a clamping mechanism, for example, the clamping mechanism comprises two clamping jaws, when the two clamping jaws are loosened, the rotating shaft assembly 300 can rotate in the containing cavity 101, and when the two clamping jaws clamp the rotating shaft assembly 300, the rotating shaft assembly 300 is fixed. The locking assembly 400 can also release and lock the rotating shaft assembly 300 by using a pin shaft, for example, a plurality of pin holes are arranged on the box assembly 100, the pin shaft is inserted through the rotating shaft assembly 300 and any pin hole, so that the rotating shaft assembly 300 is fixed relative to the box assembly 100, and when the pin shaft is pulled out, the rotating shaft assembly 300 can rotate relative to the box assembly 100.

[0062] The simulated tissues can be a spine, a rib, an organ in an abdominal cavity and the like, and the surgery demonstration device in the scheme can be used to simulate different surgeries according to different simulated tissues.

[0063] In the embodiment, the top wall 110 of the box assembly 100 is provided with two simulated channels 102, in actual use, one simulated channel 102 can be used to simulate single-channel hole mirror surgery, and two simulated channels 102 can be used to simulate double-channel endoscope surgery.

[0064] In one embodiment, the housing assembly 100 includes two opposing first sidewalls 120, and the two ends of the pivot assembly 300 extend through the first sidewalls 120 to the outside of the receiving cavity 101, and at least one end of the pivot assembly 300 is provided with a locking assembly 400.

[0065] Reference Figure 1 In an embodiment of this invention, the housing assembly 100 includes two opposing first sidewalls 120. The two ends of the rotating shaft assembly 300 rotatably pass through one of the first sidewalls 120, such that a portion of the rotating shaft assembly 300 is located inside the receiving cavity 101, and the other portion is located outside the receiving cavity 101. A locking component 400 can be provided only at one end of the rotating shaft assembly 300, or locking components 400 can be provided at both ends of the rotating shaft assembly 300. Since both ends of the rotating shaft assembly 300 extend outside the receiving cavity 101, the user can adjust the rotation of the rotating shaft assembly 300 from the outside, thereby adjusting the orientation of the simulated tissue without opening the housing assembly 100, thus improving the adjustment flexibility and ease of use of the surgical demonstration device.

[0066] In one embodiment, the locking assembly 400 includes:

[0067] The first locking member 410 is sleeved on the rotating shaft assembly 300 and located outside the receiving cavity 101. The first locking member 410 can rotate synchronously with the rotating shaft assembly 300.

[0068] The second locking member 420 is sleeved on the rotating shaft assembly 300 and located inside the receiving cavity 101. The second locking member 420 is threadedly connected to the rotating shaft assembly 300. The first locking member 410 and the second locking member 420 can move closer to or further away from each other.

[0069] When the first locking member 410 and the second locking member 420 approach each other and clamp the first sidewall 120, the locking assembly 400 is in a locked state; when the first locking member 410 and the second locking member 420 move away from the first sidewall 120, the locking assembly 400 is in a released state.

[0070] Reference Figure 2In an embodiment of this utility model, the locking assembly 400 includes a first locking member 410 and a second locking member 420. The first locking member 410 is located outside the receiving cavity 101, sleeved on the outside of the rotating shaft assembly 300, and can rotate synchronously with the rotating shaft assembly 300. The second locking member 420 is located inside the receiving cavity 101, sleeved on the outside of the rotating shaft assembly 300, and threadedly connected to the rotating shaft assembly 300. Through the threaded connection, the second locking member 420 can move along the axial direction of the rotating shaft assembly 300, thereby moving closer to or away from the first locking member 410. When the second locking member 420 approaches the first locking member 410, causing the first locking member 410 and the second locking member 420 to clamp the first sidewall 120, the rotating shaft assembly 300 cannot rotate relative to the housing assembly 100, thereby locking the rotating shaft assembly 300 with the locking member 400. When the second locking member 420 moves away from the first sidewall 120, the first locking member 410 and the second locking member 420 no longer apply pressure to the first sidewall 120, allowing the rotating shaft assembly 300 to rotate freely relative to the housing assembly 100, thereby releasing the rotating shaft assembly 300 with the locking member 400. By clamping the rotating shaft assembly 300 with the first locking member 410 and the second locking member 420, the rotation direction of the rotating shaft assembly 300 can be infinitely adjusted, allowing the simulated tissue to be arbitrarily adjusted around the axis of the rotating shaft assembly 300, thus improving the flexibility of the surgical demonstration device. Users can lock and release the locking assembly 400 simply by rotating the second locking member 420; the direction of the rotating shaft assembly 300 can be adjusted simply by rotating the first locking member 410, making operation convenient. Furthermore, when the first locking member 410 and the second locking member 420 clamp the first sidewall 120, the axial movement of the rotating shaft assembly 300 is restricted, preventing the simulated tissue from moving axially along the rotating shaft assembly 300, further improving the stability of the simulated tissue.

[0071] In one embodiment, the locking assembly 400 further includes a first seal 430, which is disposed inside the receiving cavity 101 and between the first sidewall 120 and the first locking member 410.

[0072] Reference Figure 2In an embodiment of this utility model, a first sealing member 430 is provided between the first sidewall 120 and the first locking member 410. The first sealing member 430 is made of a material with elasticity and sealing properties, such as rubber or silicone. The first seal 430 helps ensure the sealing between the first sidewall 120 and the first locking member 410, preventing liquid inside the receiving cavity 101 from leaking into the external environment. In addition, when the locking assembly 400 is in the locked state, the elastic first seal 430 is deformed under pressure between the first sidewall 120 and the first locking member 410. The elastic force generated by the first seal 430 can increase the normal pressure between the first sidewall 120 and the first seal 430, and the normal pressure between the first locking member 410 and the first seal 430, thereby increasing the friction between the first sidewall 120 and the first seal 430, and the friction between the first locking member 410 and the first seal 430. This helps to prevent loosening, ensure the locking effect of the locking assembly 400 on the rotating shaft assembly 300, improve the stability of the rotating shaft assembly 300, and thus avoid accidental rotation of the simulated tissue.

[0073] In one embodiment, the first locking member 410 has a first anti-loosening groove 4111 on the side facing the first sealing member 430. Multiple first anti-loosening grooves 4111 are spaced apart along the circumferential axis of the rotating shaft assembly 300. When the rotating shaft assembly 300 is locked, a portion of the first sealing member 430 enters the first anti-loosening groove 4111; and / or,

[0074] A second anti-loosening groove 122 is provided on the side of the first sidewall 120 facing the first seal 430. Multiple second anti-loosening grooves 122 are spaced apart along the circumferential axis of the shaft assembly 300. When the shaft assembly 300 is locked, a portion of the first seal 430 enters the second anti-loosening groove 122; and / or,

[0075] The first sidewall 120 is provided with a receiving groove 121 on the side facing the first seal 430, and the first seal 430 is at least partially disposed in the receiving groove 121.

[0076] Reference Figure 2 and Figure 5In this embodiment of the invention, a plurality of first anti-loosening grooves 4111 are provided on the side of the first locking member 410 facing the first sealing member 430, and the plurality of first anti-loosening grooves 4111 are arranged at intervals around the circumference of the rotating shaft assembly 300. When the locking assembly 400 is in the locked state, the first sealing member 430 is deformed under pressure, causing part of the first sealing member 430 to enter into the first anti-loosening groove 4111. The first sealing member 430 embedded in the first anti-loosening groove 4111 further increases the friction between the first locking member 410 and the first sealing member 430, thereby further reducing the possibility of accidental rotation of the rotating shaft assembly 300, thus avoiding accidental rotation of simulated tissue. Specifically, in this embodiment, the plurality of first anti-loosening grooves 4111 are evenly and equally spaced around the circumference of the rotating shaft assembly 300.

[0077] Reference Figure 3 and Figure 4 In this embodiment of the invention, a plurality of second anti-loosening grooves 122 are provided on the side of the first sidewall 120 facing the first seal 430, and the plurality of second anti-loosening grooves 122 are arranged at intervals around the circumference of the rotating shaft assembly 300. When the locking assembly 400 is in the locked state, the first seal 430 is deformed by pressure, causing part of the first seal 430 to enter into the second anti-loosening groove 122. The first seal 430 embedded in the second anti-loosening groove 122 further increases the friction between the first sidewall 120 and the first seal 430, thereby further reducing the possibility of accidental rotation of the rotating shaft assembly 300, thus avoiding accidental rotation of simulated tissue. Specifically, in this embodiment, the plurality of second anti-loosening grooves 122 are evenly arranged at equal intervals around the circumference of the rotating shaft assembly 300.

[0078] Reference Figures 2 to 4 In this embodiment of the invention, a receiving groove 121 is provided on the side of the first sidewall 120 facing the first seal 430. The receiving groove 121 is used to receive the first seal 430, making the structure of the surgical demonstration device more compact. Specifically, in this embodiment, a second anti-loosening groove 122 is provided at the bottom of the receiving groove 121.

[0079] In one embodiment, the locking assembly 400 further includes a second seal 440, which is disposed outside the receiving cavity 101 and between the first sidewall 120 and the second locking member 420.

[0080] Reference Figure 2In an embodiment of this utility model, a second sealing member 440 is provided between the first sidewall 120 and the second locking member 420. The second sealing member 440 is made of a material with elasticity and sealing properties, such as rubber or silicone. The second seal 440 helps ensure the sealing between the first sidewall 120 and the second locking member 420, preventing liquid inside the receiving cavity 101 from leaking into the external environment. Furthermore, when the locking assembly 400 is in the locked state, the elastic second seal 440 is deformed under pressure between the first sidewall 120 and the second locking member 420. The elastic force generated by the second seal 440 increases the normal pressure between the first sidewall 120 and the second seal 440, and between the second locking member 420 and the second seal 440, thereby increasing the friction between the first sidewall 120 and the second seal 440, and between the second locking member 420 and the second seal 440. This prevents loosening, ensures the locking effect of the locking assembly 400 on the rotating shaft assembly 300, improves the stability of the rotating shaft assembly 300, and thus avoids accidental rotation of the simulated tissue.

[0081] In one embodiment, the locking assembly 400 further includes a first fastener 450, which locks the first locking member 410 and the pivot assembly 300; and / or,

[0082] The first locking member 410 includes a sleeve 411 and a torsion bar 412. The sleeve 411 is sleeved on the outside of the rotating shaft assembly 300. One end of the torsion bar 412 is located on the outer peripheral wall of the sleeve 411, and the other end of the torsion bar 412 extends away from the sleeve 411. At least two torsion bars 412 are arranged at circumferential intervals along the sleeve 411.

[0083] Reference Figure 2 and Figure 4 In this embodiment of the invention, the locking assembly 400 further includes a first fastener 450, which connects the first locking member 410 and the rotating shaft assembly 300, enabling the first locking member 410 and the rotating shaft assembly 300 to rotate synchronously. The first fastener 450 can be in the form of a bolt, screw, or pin. Specifically, in this embodiment, the first fastener 450 is a bolt, and the first locking member 410 has a threaded hole. The first fastener 450 is threadedly connected to the threaded hole. By tightening the first fastener 450, the end of the first fastener 450 is tightly pressed against the outer wall of the rotating shaft assembly 300, thereby achieving a fixed connection between the first locking member 410 and the rotating shaft assembly 300. The structure is simple and easy to implement.

[0084] Reference Figure 4 and Figure 5In this embodiment of the present invention, the first locking member 410 includes a sleeve 411 and a torsion bar 412. The sleeve 411 is sleeved on the outside of the rotating shaft assembly 300 and connected to the rotating shaft assembly 300 through a first fastener 450. One end of the torsion bar 412 is fixed on the outer peripheral wall of the sleeve 411, and the other end extends away from the sleeve 411. By rotating the torsion bar 412, the sleeve 411 is rotated, thereby rotating the rotating shaft assembly 300, realizing the adjustment of the orientation of the simulated tissue, and improving the convenience of rotating the first locking member 410. Along the circumference of the sleeve 411, at least two torsion bars 412 are arranged at intervals to facilitate the user to apply force when operating the torsion bars 412. Specifically, in this embodiment, three torsion bars 412 are provided on the outside of the sleeve 411, and the three torsion bars 412 are equally spaced on the outer wall of the sleeve 411.

[0085] In one embodiment, the surgical demonstration device further includes a height adjustment mechanism disposed in the housing assembly 100, which is used to adjust the height difference between the rotating shaft assembly 300 and the simulation channel 102 so that the height difference between the simulated tissue and the simulation channel 102 is adjustable.

[0086] In embodiments of this invention, the surgical demonstration device further includes a height adjustment mechanism. This mechanism adjusts the vertical distance between the rotating shaft assembly 300 and the simulation channel 102, thereby adjusting the height of the simulated tissue to simulate different surgical situations. This allows the surgical demonstration device to adapt to different surgical training needs and provide a more realistic surgical experience. The height adjustment mechanism can be implemented using a combination of a slide rail and a slider. For example, a slide rail extending along the height direction can be provided on the inner wall of the housing assembly 100, with the slider slidably mounted on the slide rail. The rotating shaft assembly 300 is connected to the slider, thus moving up and down with the slider to achieve height adjustment. Alternatively, the height adjustment mechanism can be implemented by providing through holes at different heights on the side wall of the housing assembly 100, with the rotating shaft assembly 300 passing through these through holes to achieve height adjustment.

[0087] In one embodiment, the height adjustment mechanism includes a plurality of positioning structures 510 spaced apart along the height direction of the housing assembly 100. The rotating shaft assembly 300 is detachably connected to the positioning structures 510. The height difference between the rotating shaft assembly 300 and the simulation channel 102 is adjusted by connecting the positioning structures 510 of different heights through the rotating shaft assembly 300, so as to adjust the height of the simulated tissue relative to the top wall 110.

[0088] In this embodiment of the invention, the height adjustment mechanism includes multiple positioning structures 510. Each positioning structure 510 can be a fixing point in the form of a hole, slot, boss, or snap-fit, and is spaced apart along the height direction of the housing assembly 100. When it is necessary to adjust the height difference between the rotating shaft assembly 300 and the simulation channel 102, the rotating shaft assembly 300 is first disassembled from the current positioning structure 510, then moved to another higher or lower positioning structure 510 and reconnected, thereby adjusting the relative distance between the simulated tissue and the simulated channel 102. Through simple disassembly and reconnection, the user can quickly adjust the height of the rotating shaft assembly 300 to adapt to different simulated surgical needs, improving the convenience of height adjustment. Furthermore, the structure is relatively simple, which helps reduce the manufacturing cost of the surgical demonstration device.

[0089] In one embodiment, the positioning structure 510 includes two positioning holes 511 arranged opposite to each other. The two positioning holes 511 are provided on two opposite side walls of the housing assembly 100, and the two ends of the rotating shaft assembly 300 are respectively inserted through one positioning hole 511.

[0090] Reference Figure 6 In this embodiment of the invention, the positioning structure 510 includes two positioning holes 511, which are respectively disposed on two opposite side walls of the housing assembly 100. Both ends of the rotating shaft assembly 300 pass through the positioning holes 511 on both sides of the housing assembly 100, which helps maintain the balance and stability of the rotating shaft assembly 300. Height positioning is achieved through the positioning holes 511, resulting in a simple structure that is easy to manufacture. Specifically, in this embodiment, the rotating shaft assembly 300 can also rotate within the positioning holes 511, thereby adjusting the orientation of the simulated tissue. Multiple pairs of positioning holes 511 along the height direction achieve both height adjustment and orientation adjustment of the simulated tissue, simplifying the structure of the surgical demonstration device.

[0091] In one embodiment, the surgical demonstration device further includes a plurality of third seals 600, each third seal 600 being detachably connected to a positioning hole 511 to open or seal the positioning hole 511.

[0092] Reference Figure 1In this embodiment of the invention, when the surgical demonstration device is in use, the rotating shaft assembly 300 only needs to be inserted into one pair of positioning holes 511, leaving the other positioning holes 511 unused. Therefore, multiple third sealing elements 600 are provided, each of which can be detachably connected to one positioning hole 511. By sealing the unused positioning holes 511 with the third sealing elements 600, liquid inside the housing assembly 100 is prevented from flowing out, and foreign objects such as dust from the external environment are prevented from entering the housing assembly 100, thereby extending the service life of the surgical demonstration device. The third sealing elements 600 are made of materials such as rubber, silicone, and plastic to ensure good sealing performance and durability. The third sealing elements 600 are detachably connected to the positioning holes 511 through threads, snaps, interference fits, or other means. Specifically, when it is necessary to adjust the height of the shaft assembly 300, first remove the third seal 600 of the corresponding positioning hole 511, adjust the shaft assembly 300 to the new positioning hole 511 position, and then reinstall the third seal 600 at the original positioning hole 511 to ensure that the unused positioning hole 511 is sealed.

[0093] In one embodiment, the housing assembly 100 is further provided with an inlet hole 103 and an outlet hole 104 communicating with the receiving cavity 101. The inlet hole 103 is located between the top wall 110 of the housing assembly 100 and the rotating shaft assembly 300. The distance between the outlet hole 104 and the bottom wall of the housing assembly 100 is less than the distance between the inlet hole 103 and the bottom wall of the housing assembly 100.

[0094] In this embodiment of the invention, the housing assembly 100 has a liquid inlet 103 and a liquid outlet 104. Liquids such as water or saline enter the receiving cavity 101 through the liquid inlet 103 and then flow out through the liquid outlet 104, simulating surgical water injection operations, which is closer to the real surgical environment and thus improves the simulation effect of the surgical demonstration device. The liquid inlet 103 is located between the top wall 110 and the rotating shaft assembly 300 of the housing assembly 100, ensuring that the liquid in the receiving cavity 101 immerses the simulated tissue, which conforms to the real surgical scenario. The distance between the liquid outlet 104 and the bottom wall is smaller than the distance between the liquid inlet 103 and the bottom wall, so that the liquid inside the housing assembly 100 can be naturally discharged from the liquid outlet 104 under the action of gravity, improving the convenience of liquid discharge. Specifically, in this embodiment, the liquid inlet 103 and the liquid outlet 104 are provided on two opposite side walls of the housing assembly 100, which improves the fluidity of the liquid and makes it easier for the liquid to pass through the simulated tissue during circulation.

[0095] In one embodiment, an inlet hole 103 is formed in one of the positioning holes 511 between the top wall 110 of the housing assembly 100 and the rotating shaft assembly 300; and / or, an outlet hole 104 is formed in one of the positioning holes 511 between the bottom wall of the housing assembly 100 and the rotating shaft assembly 300.

[0096] ReferenceFigure 6 In this embodiment of the present invention, among the multiple positioning holes 511 that the rotating shaft assembly 300 does not pass through, a third seal 600 is selected from the positioning holes 511 located above the rotating shaft assembly 300 and removed as an injection hole, and a third seal 600 is selected from the positioning holes 511 located below the rotating shaft assembly 300 and removed as an outlet hole 104. There is no need to set up additional inlet holes 103 and outlet holes 104, so that the positioning holes 511 can not only be used to adjust the height and orientation of the simulated tissue, but also serve as the inlet and outlet of liquid, simplifying the structure of the surgical demonstration device and reducing manufacturing costs.

[0097] In one embodiment, the rotating shaft assembly 300 includes a support tube 310 and telescopic rods 320 respectively sleeved at both ends of the support tube 310. The bracket assembly 200 is fixed to the support tube 310. The telescopic rods 320 can move axially relative to the support tube 310. The end of each telescopic rod 320 away from the support tube 310 is connected to the housing assembly 100.

[0098] Reference Figure 1 and Figure 7 In this embodiment of the invention, the rotating shaft assembly 300 includes a support tube 310 and telescopic rods 320 located at both ends of the support tube 310. The support assembly 200 is disposed on the support tube 310. The two telescopic rods 320 slide through both ends of the support tube 310, allowing the length of the entire rotating shaft assembly 300 to extend or retract. When the height of the simulated tissue needs to be adjusted, the telescopic rods 320 retract, shortening the length of the rotating shaft assembly 300, making it easier for the rotating shaft assembly 300 to exit from the positioning holes 511 on both sides. Then, the rotating shaft assembly 300 is moved to the positioning hole 511 at the desired height, and the telescopic rods 320 extend, lengthening the rotating shaft assembly 300. The two telescopic rods 320 respectively insert into the positioning holes 511 on both sides, thereby achieving height adjustment and improving the convenience of height adjustment. Specifically, in this embodiment, since the end of the telescopic rod 320 away from the support tube 310 is provided with a locking component 400, before the telescopic rod 320 retracts, the first locking components 410 on both sides need to be removed first. Then the telescopic rod 320 retracts and exits from the positioning holes 511 on both sides. After the telescopic rod 320 extends and enters the required positioning hole 511, the first locking component 410 is then sleeved on the outside of the telescopic rod 320 and fixed to the telescopic rod 320.

[0099] In one embodiment, the pivot assembly 300 further includes a second fastener 330, which is detachably connected to the telescopic rod 320 and the support tube 310 so that the telescopic rod 320 is fixed to the support tube 310.

[0100] Reference Figure 7In this embodiment of the invention, the rotating shaft assembly 300 further includes a second fastener 330. Each telescopic rod 320 is provided with at least one second fastener 330. When the telescopic rod 320 extends to make the length of the rotating shaft assembly 300 meet the usage requirements, the second fastener 330 fixes the telescopic rod 320 to the support tube 310, preventing the telescopic rod 320 from sliding relative to the support tube 310. This ensures the accuracy of the length of the rotating shaft assembly 300 and prevents changes in the position of the telescopic rod 320 due to vibration or external force during use, thereby improving the stability of the simulated tissue during simulated surgery. The second fastener 330 can be in the form of a bolt, screw, or pin. Specifically, in this embodiment, the second fastener 330 is a bolt. The support tube 310 has a threaded hole, and the second fastener 330 is threaded into the threaded hole. By tightening the second fastener 330, the end of the second fastener 330 is tightly pressed against the outer wall of the telescopic rod 320, thereby achieving a fixed connection between the support tube 310 and the telescopic rod 320. The structure is simple and easy to implement.

[0101] In one implementation, such as Figure 1 As shown, the pivot assembly 300 is located in the middle of the receiving cavity 101, and its two ends penetrate the opposite side walls of the housing assembly 100. The bracket assembly 200 is connected to the middle of the pivot assembly 300. This reduces the number of connections between components and improves reliability.

[0102] In another embodiment, there are at least two pivot assemblies 300, each connected to opposite sidewalls of the housing assembly 100, and each end of the support assembly 200 is connected to a pivot assembly 300. Having at least two pivot assemblies 300 connected to the support assembly 200 allows for flexible adjustment of the position and angle of the simulated tissue relative to the housing assembly 100, facilitating more flexible adjustments during surgical demonstrations.

[0103] In one embodiment, the support assembly 200 includes:

[0104] The base plate 210 is fixed to the rotating shaft assembly 300, and the base plate 210 is provided with at least two mounting holes 211;

[0105] A clamp 220, with both ends of the clamp passing through two mounting holes 211, and a base plate 210 and clamp 220 together forming a mounting space to fix the simulated tissue within the mounting space; and

[0106] The limiting component 230 is located on the side of the base plate 210 away from the installation space and is detachably connected to the clamp 220 to prevent the clamp 220 from coming out of the mounting hole 211.

[0107] Reference Figure 7In this embodiment of the invention, the support assembly 200 includes a base plate 210, a clamp 220, and a limiting assembly 230. The base plate 210 is fixed to the support tube 310, providing a stable support surface for the simulated tissue. The base plate 210 has at least two mounting holes 211. The clamp 220 is mounted on the base plate 210 through the mounting holes 211, forming an installation space for placing the simulated tissue between the base plate 210 and the clamp 220. The clamp 220 surrounds and fixes the simulated tissue, ensuring that the simulated tissue is securely fixed and will not move or fall off during the simulated surgery. The limiting assembly 230 is located on the side of the base plate 210 away from the installation space and is detachably connected to the clamp 220. It is used to prevent the clamp 220 from coming out of the mounting holes 211, thereby ensuring that the simulated tissue is securely fixed. On the other hand, after removing the limiting assembly 230, the clamp 220 can be removed from the mounting holes 211, thereby facilitating the removal of the simulated tissue. The detachable engagement of the clamp 220 and the limiting component 230 makes the installation and replacement of the simulated tissue easier and faster. In addition, the clamp 220 can adapt to simulated tissues of different sizes and shapes, improving the versatility of the support assembly 200.

[0108] In one embodiment, a plurality of mounting holes 211 are spaced apart along the length direction of the base plate 210, and a plurality of mounting holes are spaced apart along the width direction of the base plate 210; and / or,

[0109] The outer wall of the support tube 310 is provided with a flat rectangular structure 311, and the bottom plate 210 is attached to the flat rectangular structure 311.

[0110] Reference Figure 7 In the embodiments of this utility model, multiple mounting holes 211 are spaced apart along the length direction of the base plate 210 and multiple mounting holes are spaced apart along the width direction of the base plate 210. This allows multiple clamps 220 to be installed on the base plate 210 and facilitates the adjustment of the position of each clamp 220, thereby adapting to the specific size and shape of different simulated tissues and improving the adaptability and versatility of the support assembly 200.

[0111] Reference Figure 7 In an embodiment of this utility model, the outer wall of the support tube 310 is provided with a flat square structure 311, which means that one side of the outer wall of the support tube 310 has a flat square surface instead of a round arc shape. This increases the contact area between the support tube 310 and the base plate 210, prevents the base plate 210 from rotating around the support tube 310, and thus improves the stability of the bracket assembly 200.

[0112] In one embodiment, the limiting component 230 includes:

[0113] Limiting element 231 is sleeved on both ends of clamp 220;

[0114] The third locking member 232 is located at both ends of the clamp 220 and is detachably connected to the end of the clamp 220.

[0115] Reference Figure 7 and Figure 8 In this embodiment of the invention, the limiting component 230 includes a limiting member 231 and a third locking member 232. The limiting member 231 is located on the side of the support tube 310 away from the base plate 210 and is sleeved on both ends of the clamp 220, ensuring that neither end of the clamp 220 can detach from the mounting hole 211. The third locking member 232 is located on the side of the limiting member 231 away from the support tube 310 and is detachably connected to the end of the clamp 220, preventing the limiting member 231 from separating from the clamp 220 and further ensuring that the clamp 220 cannot detach from the mounting hole 211, thereby further enhancing the stability of the simulated tissue. The dual fixation of the limiting member 231 and the third locking member 232 improves the stability of the simulated tissue and reduces the risk of the simulated tissue falling off. The third locking member 232 can be detachably connected to the end of the clamp 220 using a nut, buckle, or other similar means.

[0116] In one embodiment, the top wall 110 of the housing assembly 100 is an elastic structure.

[0117] In the embodiments of this utility model, the top wall 110 of the box assembly 100 is made of rubber or silicone or similar materials, making the top wall 110 an elastic structure that simulates the softness and elasticity of human tissue, providing users with an experience closer to a real surgical scenario and improving the practice effect of simulated surgery.

[0118] In one embodiment, the top wall 110 of the housing assembly 100 includes a first elastic layer 111 and a second elastic layer 112, wherein the second elastic layer 112 is disposed on the side of the first elastic layer 111 opposite to the receiving cavity 101.

[0119] Wherein, the elastic modulus of the first elastic layer 111 is greater than the elastic modulus of the second elastic layer 112; and / or, the thickness of the first elastic layer 111 is greater than the thickness of the second elastic layer 112.

[0120] Reference Figure 1In this embodiment of the invention, the top wall 110 of the housing assembly 100 adopts a double-layer structure, including a first elastic layer 111 and a second elastic layer 112. The combination of the first elastic layer 111 and the second elastic layer 112 can better simulate the layered feel of human tissue. The elastic modulus of the first elastic layer 111 is greater than that of the second elastic layer 112; that is, the first elastic layer 111 is relatively harder, while the second elastic layer 112 is relatively softer, thus simulating different parts of human tissue. The second elastic layer 112 simulates skin, and the first elastic layer 111 simulates muscle. Specifically, the thickness of the first elastic layer 111 simulating muscle is greater than the thickness of the second elastic layer 112 simulating skin, further increasing the realism of the simulation and providing users with a more realistic simulated surgical experience.
