[0001] This utility model relates to the field of biological tissue clamp technology, and more specifically, to a biological tissue clamp with a stable auxiliary structure. Background Technology
[0002] Biomechanical experiments on biomaterials are crucial for evaluating the properties of tissue materials. This experimental procedure can effectively detect the performance of biomaterials under various mechanical stresses such as tension, compression, bending, and torsion. The fixtures often use two pairs of rough-surfaced friction blocks to clamp the two ends of the biomaterial before conducting biomechanical experiments.
[0003] A search revealed that patent publication number CN212688092U discloses a movable biomimetic microfluidic biochip device. The device includes a mounting base, a drive module, a clamping module, and a microfluidic biochip. The clamping module comprises a first clamping unit and a second clamping unit, both located on the mounting base. This microfluidic biochip, in conjunction with the first clamping module, the second clamping module, and the drive module, can simulate muscle contraction and relaxation. It can be used for drug screening and disease mechanism research model construction under tissue movement conditions, offering advantages such as ease of operation and low cost.
[0004] Currently, many test items suffer from insufficient stability during clamping, resulting in poor clamping performance and affecting the quality of their clamping and fixation.
[0005] Therefore, a biological tissue clamp with a stable auxiliary structure is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a biological tissue clamp with a stable auxiliary structure to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a biological tissue clamp with a stable auxiliary structure, comprising a base plate, a right fixing frame fixedly mounted on the top of the base plate, a threaded rod threadedly mounted on one side of the fixing frame, a right clamping plate fixedly mounted on the end of the threaded rod away from the rotating disk, a fixing column fixedly mounted inside the fixing frame, a telescopic rod movably mounted inside the fixing column, a limiting plate fixedly mounted on the bottom of the telescopic rod, the limiting plate being located inside the fixing column, a compression spring sleeved on the outside of the telescopic rod, and a left clamping plate fixedly connected to one side of the telescopic rod.
[0008] Preferably, a lifting mechanism is fixedly installed above the substrate, a bearing panel is fixedly installed on the top of the lifting mechanism, and a test pool is placed above the bearing panel. The test pool can be replaced as needed.
[0009] Preferably, a rotating disk is fixedly installed on one side of the threaded rod, and a right handle is fixedly installed on one side of the rotating disk.
[0010] Preferably, a bearing is provided at the end of the threaded rod away from the rotating disk, and the bearing is installed on the upper side of the right clamping plate.
[0011] Preferably, the top of the fixing frame is provided with a sliding groove, and the top of the right clamping plate and the left clamping plate are fixedly connected with a connecting rod, which passes through the sliding groove and extends to the top of the fixing frame.
[0012] Preferably, the connecting rod moves within the slide groove, and an anti-detachment plate is fixedly attached to the top of the connecting rod.
[0013] The technical effects and advantages of this utility model are as follows:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] As attached Figures 1 to 3 A biological tissue clamp with a stable auxiliary structure is shown, comprising a base plate 1, a right fixing frame 2 fixedly mounted on the top of the base plate 1, a threaded rod 6 threadedly mounted on one side of the fixing frame 2, a right clamping plate 9 fixedly mounted on the end of the threaded rod 6 away from the rotating disk 7, a fixing post 11 fixedly mounted inside the fixing frame 2, a telescopic rod 12 movably mounted inside the fixing post 11, a limiting plate 13 fixedly mounted on the bottom of the telescopic rod 12, the limiting plate 13 being located inside the fixing post 11, a compression spring 14 sleeved on the outside of the telescopic rod 12, and a left clamping plate 15 fixedly connected to one side of the telescopic rod 12.
[0023] Specifically, by utilizing the cooperation between the threaded rod 6 and the rotating disk 7, the right clamping plate 9 can be controlled to move towards the left clamping plate 15. When the rotating disk 7 is rotated, it drives the threaded rod 6 to rotate, and through the interaction of the threads, the right clamping plate 9 gradually moves closer to the left clamping plate 15. The support composed of the fixed column 11, the telescopic rod 12, the limiting plate 13, and the compression spring 14 provides a stable and adjustable support force for the left clamping plate 15. Under the action of the compression spring 14, the telescopic rod 12 can automatically adjust its length according to the thickness of the clamped object, ensuring that the left clamping plate 15 always maintains an appropriate distance from the right clamping plate 9, neither too tight to cause damage to the object, nor too loose to be effectively clamped, making the entire clamping process exceptionally simple and efficient.
[0024] Example 2
[0025] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details:
[0026] In a preferred embodiment, a lifting mechanism 3 is fixedly installed above the substrate 1, and a bearing panel 4 is fixedly installed on the top of the lifting mechanism 3. A test pool 5 is placed above the bearing panel 4, and the test pool 5 can be replaced as needed. Furthermore, the vertical position of the bearing panel 4 can be flexibly adjusted using the lifting mechanism 3, and the test pool 5 at the top of the bearing panel 4 provides great convenience for placing and testing the clamped object. By operating the lifting mechanism 3, the height of the bearing panel 4 can be precisely controlled, and the test pool 5 installed above it provides a good environment for various experiments on the clamped object.
[0027] In a preferred embodiment, a rotating disk 7 is fixedly installed on one side of the threaded rod 6, and a handle 8 is fixedly installed on one side of the rotating disk 7. Furthermore, installing the rotating disk 7 on one side of the threaded rod 6 increases the direct contact area with the threaded rod 6, improves the stability and torque transmission efficiency during rotation, and provides a more stable point of force. The rotating disk 7 effectively prevents slippage or damage caused by direct action on the threaded rod 6, even under high torque requirements, ensuring the safety and reliability of operation. A handle 8 is also installed at the center or edge of the rotating disk 7, which undoubtedly provides great convenience for the operator. Whether performing clockwise or counterclockwise rotation, it can be easily completed by holding the handle 8, greatly reducing the physical strength and skill requirements required to rotate the threaded rod 6.
[0028] In a preferred embodiment, a bearing 10 is provided at the end of the threaded rod 6 away from the rotating disk 7, and the bearing 10 is installed on the upper side of the right clamping plate 9. Furthermore, the bearing 10 is installed on one side of the rotating disk 7, realizing a stable connection between the threaded rod 6 and the right clamping plate 9. The bearing 10 contains rolling elements, inner and outer rings, and a cage, which can greatly reduce frictional resistance during rotation, ensuring smoother and more stable relative movement between the rotating disk 7 and the threaded rod 6. Through the connection of the bearing 10, the rotational power of the threaded rod 6 can be efficiently transmitted to the right clamping plate 9, thereby realizing precise adjustment or movement of the clamped object and improving the overall rigidity and stability of the system.
[0029] In a preferred embodiment, the top of the fixing frame 2 is provided with a sliding groove 16, and the top of the right clamping plate 9 and the left clamping plate 15 are fixedly connected with a connecting rod 17. The connecting rod 17 passes through the sliding groove 16 and extends to the top of the fixing frame 2. Furthermore, the sliding groove 16 provided on the fixing frame 2 provides a smooth moving track for the connecting rod 17, which not only allows the connecting rod 17 to slide freely in the sliding groove 16, but also ensures that when the right clamping plate 9 and the left clamping plate 15 on both sides move, they can maintain a parallel moving trajectory. This ensures that the clamped object will not deviate or tilt during the movement, thereby greatly improving the accuracy and stability of clamping.
[0030] In a preferred embodiment, the connecting rod 17 moves within the slide groove 16, and an anti-detachment plate 18 is fixedly attached to the top of the connecting rod 17. Furthermore, by connecting the anti-detachment plate 18 to the connecting rod 17, the risk of the connecting rod 17 accidentally detaching from the slide groove 16 during movement is prevented. As a safety device, the edge of the anti-detachment plate 18 fits tightly against the side wall of the slide groove 16, forming an effective barrier. This ensures that the connecting rod 17 can remain stably within the slide groove 16 even under external force or operational errors, allowing the user to focus more on the clamping task itself without worrying excessively about the connecting rod 17 falling off.
[0031] The working process of this utility model is as follows: Before using this device, the first step is to conduct a comprehensive and detailed inspection of all components to ensure that each part is in good working condition and free from damage or looseness. After the inspection is completed, the height of the test pool 5 above the support panel 4 can be adjusted by operating the lifting mechanism 3 to adapt to the needs of different experiments and ensure the operator's comfort during operation. Next, when preparing to clamp the item, the item to be clamped is placed securely on the upper side of the left clamping plate 15 and the right clamping plate 9. Then, the operator only needs to use their hands... The rotating handle 8 drives the threaded rod 6 to rotate smoothly inside the bearing 10, thereby pushing the right clamping plate 9 steadily closer to the left clamping plate 15 until a stable clamping of the object is achieved. A connecting rod 17 is connected to the top of the right clamping plate 9 and the left clamping plate 15, ensuring that the connecting rod 17 can slide smoothly inside the slide groove 16 when the two clamping plates move, effectively limiting the offset or tilt of the clamping plates, thereby ensuring the stability and accuracy of the clamped object during the movement process. This not only improves the clamping effect but also enhances the reliability and practicality of the entire device.
