[0046] This invention proposes an adjustable surgical demonstration device to prevent loosening.

[0047] Please see Figures 1-2 , Figure 1A cross-section of an embodiment of the adjustable surgical demonstration device for preventing loosening provided by this utility model. Figure 1 , Figure 2 for Figure 1 A magnified view of a portion of point A in the middle.

[0048] In one embodiment of this utility model, the adjustable surgical demonstration device for preventing loosening includes:

[0049] The housing assembly 100 has a receiving cavity 101. At least one side wall of the housing assembly 100 is a transparent structure, and the top wall 110 of the housing assembly 100 has at least one channel 102 communicating with the receiving cavity 101.

[0050] The scaffold assembly 200 is disposed within the receiving cavity 101 and is used to fix the simulated tissue.

[0051] The rotating shaft assembly 300 has its central part disposed in the receiving cavity 101, and its two ends penetrate through the opposite side walls of the housing assembly 100. The rotating shaft assembly 300 is rotatable relative to the housing assembly 100. The support assembly 200 is connected to the central part of the rotating shaft assembly 300 and can rotate synchronously with the rotating shaft assembly 300. The rotating shaft assembly 300 is used to adjust the orientation of the simulated tissue.

[0052] A locking component 400 is disposed at the end of the rotating shaft assembly 300 and is used to lock or release the rotating shaft assembly 300.

[0053] The anti-loosening component 500 is located between the shaft assembly 300 and the housing assembly 100, and is used to prevent the shaft assembly 300 from rotating after it is locked.

[0054] The adjustable surgical demonstration device of this utility model includes a housing assembly 100, a support assembly 200, a rotating shaft assembly 300, a locking assembly 400, and an anti-loosening assembly 500. The housing assembly 100 has a receiving cavity 101 inside, and the support assembly 200 is located in the receiving cavity 101 for fixing simulated tissue. Surgical instruments extend into the receiving cavity 101 through a channel 102 provided on the top wall 110 of the housing assembly 100 to perform simulated surgery on the simulated tissue. At least one side wall of the housing assembly 100 is transparent, allowing an observer to see the simulated surgical demonstration from the side. The two ends of the rotating shaft assembly 300 penetrate the opposite side walls of the housing assembly 100 and are rotatably connected to the housing assembly 100. The support assembly 200, mounted on the rotating shaft assembly 300, can rotate synchronously with the rotating shaft assembly 300. The locking assembly 400 can release or lock the rotating shaft assembly 300. When the rotating shaft assembly 300 is released, it can rotate relative to the housing assembly 100, thereby causing the support assembly 200 to adjust the orientation of the simulated tissue. When the rotating shaft assembly 300 is locked, it is fixed relative to the housing assembly 100, thus fixing the orientation of the simulated tissue and ensuring its stability during the simulated surgical procedure. The rotation of the rotating shaft assembly 300 allows for adjustment of the simulated tissue's orientation, enabling users to perform simulated surgical procedures from different angles, simulating posterior and lateral approaches, meeting more simulated surgical needs and improving the flexibility of the adjustable surgical demonstration device. The anti-loosening assembly 500 is located between the rotating shaft assembly 300 and the housing assembly 100. It prevents the rotating shaft assembly 300 from rotating after it is locked, avoiding displacement of the simulated tissue due to loosening during the surgical demonstration, improving the stability of the simulated tissue, and thus enhancing the accuracy and safety of the simulated surgery.

[0055] The locking assembly 400 can utilize a clamping mechanism to release and lock the rotating shaft assembly 300. For example, the clamping mechanism includes two grippers. When the two grippers release the rotating shaft assembly 300, the rotating shaft assembly 300 can rotate within the receiving cavity 101. When the two grippers clamp the rotating shaft assembly 300, the rotating shaft assembly 300 is fixed. Alternatively, the locking assembly 400 can utilize a pin to release and lock the rotating shaft assembly 300. For example, multiple pin holes are provided on the housing assembly 100. By passing the pin through the rotating shaft assembly 300 and any of the pin holes, the rotating shaft assembly 300 is fixed relative to the housing assembly 100. When the pin is pulled out, the rotating shaft assembly 300 can rotate relative to the housing assembly 100. The support assembly 200 can be implemented by combining a support plate with clamps, ropes, etc. The rotating shaft assembly 300 can be a solid rod or a hollow tube.

[0056] Specifically in this embodiment, the top wall 110 of the housing assembly 100 is provided with two channels 102. In actual use, only one channel 102 can be used to simulate single-channel endoscopic surgery, or two channels 102 can be used to simulate dual-channel endoscopic surgery.

[0057] In one embodiment, the housing assembly 100 has opposing first sidewalls 120, the first sidewalls 120 being provided with positioning holes 123, a plurality of positioning holes 123 being spaced apart along the height direction of the first sidewalls 120, and the two ends of the rotating shaft assembly 300 passing through the positioning holes 123 and being detachably connected to the locking assembly 400.

[0058] 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 adjustable surgical demonstration device. Specifically, the two ends of the rotating shaft assembly 300 pass through positioning holes 123 on two opposite first sidewalls 120. When it is necessary to adjust the height difference between the rotating shaft assembly 300 and the channel 102, the rotating shaft assembly 300 is first disassembled from the current positioning hole 123, then moved to another higher or lower positioning hole 123 and reconnected, thereby adjusting the relative distance between the simulated tissue and the 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 adjustable surgical demonstration device. Moreover, the height adjustment and positioning of the simulated tissue are achieved through multiple positioning holes 123, resulting in a simple structure that is easy to manufacture. In this embodiment, the rotating shaft assembly 300 can rotate within the positioning holes 123, thereby adjusting the orientation of the simulated tissue. Multiple pairs of positioning holes 123 along the height direction achieve both height adjustment and orientation adjustment of the simulated tissue, simplifying the structure of the adjustable surgical demonstration device.

[0059] In one embodiment, the locking assembly 400 includes:

[0060] 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.

[0061] 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.

[0062] When the first locking member 410 and the second locking member 420 approach each other and clamp the first sidewall 120, the rotating shaft assembly 300 is locked and cannot rotate; when the first locking member 410 and the second locking member 420 move away from the first sidewall 120, the rotating shaft assembly 300 can rotate.

[0063] Reference Figure 2 In 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, improving the flexibility of the adjustable surgical demonstration device when adjusting the direction. 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.

[0064] In one embodiment, the anti-loosening assembly 500 includes a first seal 510 disposed outside the receiving cavity 101, the first seal 510 being disposed between the first sidewall 120 and the first locking member 410.

[0065] Reference Figure 2 In an embodiment of this utility model, the anti-loosening component 500 includes a first sealing member 510 disposed outside the receiving cavity 101, and the first sealing member 510 is disposed between the first side wall 120 and the first locking member 410. The first sealing member 510 is made of a material with elasticity and sealing properties, such as rubber, silicone, etc. The first seal 510 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 510 is deformed under pressure between the first sidewall 120 and the first locking member 410. The elastic force generated by the first seal 510 can increase the normal pressure between the first sidewall 120 and the first seal 510, and the normal pressure between the first locking member 410 and the first seal 510, thereby increasing the friction between the first sidewall 120 and the first seal 510, and the friction between the first locking member 410 and the first seal 510, thus playing an anti-loosening role, ensuring the locking effect of the locking assembly 400 on the rotating shaft assembly 300, improving the stability of the rotating shaft assembly 300, and thus avoiding accidental rotation of the simulated tissue.

[0066] In one embodiment, the first locking member 410 has a first anti-loosening groove 4111 on the side facing the first sealing member 510. Multiple anti-loosening grooves 4111 are spaced apart circumferentially along the axis of the first locking member 410. When the rotating shaft assembly 300 is locked, a portion of the first sealing member 510 enters the first anti-loosening groove 4111; and / or,

[0067] The first sidewall 120 facing the first seal 510 is provided with a second anti-loosening groove 122. Multiple second anti-loosening grooves 122 are spaced apart circumferentially along the positioning hole 123. When the shaft assembly 300 is locked, a portion of the first seal 510 enters the second anti-loosening groove 122; and / or,

[0068] The first sidewall 120 is provided with a receiving groove 121 on the side facing the first seal 510, and the first seal 510 is at least partially disposed in the receiving groove 121.

[0069] 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 510. The plurality of first anti-loosening grooves 4111 are circumferentially spaced around the axis of the rotating shaft assembly 300. When the locking assembly 400 is in the locked state, the first sealing member 510 is deformed under pressure, causing part of the first sealing member 510 to enter the first anti-loosening groove 4111. The first sealing member 510 embedded in the first anti-loosening groove 4111 further increases the friction between the first locking member 410 and the first sealing member 510, 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 spaced around the axis of the rotating shaft assembly 300.

[0070] 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 510, and the plurality of second anti-loosening grooves 122 are circumferentially spaced around the axis of the rotating shaft assembly 300. When the locking assembly 400 is in the locked state, the first seal 510 is deformed by pressure, causing part of the first seal 510 to enter into the second anti-loosening groove 122. The first seal 510 embedded in the second anti-loosening groove 122 further increases the friction between the first sidewall 120 and the first seal 510, 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 spaced around the axis of the rotating shaft assembly 300.

[0071] Reference Figures 2-4 In this embodiment of the invention, a receiving groove 121 is provided on the side of the first sidewall 120 facing the first seal 510. The receiving groove 121 is used to receive the first seal 510, making the structure of the adjustable 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.

[0072] In one embodiment, the anti-loosening assembly 500 further includes a second sealing member 520 disposed inside the receiving cavity 101, the second sealing member 520 being disposed between the first sidewall 120 and the second locking member 420.

[0073] Reference Figure 2In an embodiment of this utility model, a second sealing member 520 is provided between the first sidewall 120 and the second locking member 420. The second sealing member 520 is made of a material with elasticity and sealing properties, such as rubber or silicone. The second seal 520 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 520 is deformed under pressure between the first sidewall 120 and the second locking member 420. The elastic force generated by the second seal 520 increases the normal pressure between the first sidewall 120 and the second seal 520, and between the second locking member 420 and the second seal 520, thereby increasing the friction between the first sidewall 120 and the second seal 520, and between the second locking member 420 and the second seal 520. 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.

[0074] In one embodiment, the locking assembly 400 further includes a first fastener 430, which locks the first locking member 410 and the pivot assembly 300.

[0075] Reference Figure 2 and Figure 4 In this embodiment of the invention, the locking assembly 400 further includes a first fastener 430, 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 430 can be in the form of a bolt, screw, or pin. Specifically, in this embodiment, the first fastener 430 is a bolt, and the first locking member 410 has a threaded hole. The first fastener 430 is threadedly connected to the threaded hole. By tightening the first fastener 430, the end of the first fastener 430 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.

[0076] In one embodiment, 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 disposed 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 provided at circumferential intervals along the sleeve 411.

[0077] 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 430. 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.

[0078] In one embodiment, the adjustable surgical demonstration device further includes a plurality of third seals 600, each third seal 600 being detachably connected to a positioning hole 123 to open or seal the positioning hole 123.

[0079] Reference Figure 1 In this embodiment of the invention, when the adjustable surgical demonstration device is in use, the rotating shaft assembly 300 only needs to be inserted into one pair of positioning holes 123, leaving the other positioning holes 123 unused. Therefore, multiple third sealing elements 600 are provided, each of which can be detachably connected to one positioning hole 123. By sealing the unused positioning holes 123 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 adjustable 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 123 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 123, adjust the shaft assembly 300 to the new positioning hole 123 position, and then reinstall the third seal 600 at the original positioning hole 123 to ensure that the unused positioning hole 123 is sealed.

[0080] 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.

[0081] 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 adjustable 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.

[0082] Specifically, in this embodiment, among the multiple positioning holes 123 that the rotating shaft assembly 300 does not pass through, one of the positioning holes 123 located above the rotating shaft assembly 300 is selected to remove the third seal 600 as an injection hole, and one of the positioning holes 123 located below the rotating shaft assembly 300 is selected to remove the third seal 600 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 123 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 adjustable surgical demonstration device and reducing manufacturing costs.

[0083] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
