[0002] Decellularized matrix materials are basic scaffold materials in the field of tissue engineering and regenerative medicine. This material retains its complete three-dimensional structure and has appropriate pore size, porosity, and adsorption. When used as an implant material, it can actively induce and promote the adhesion and ingrowth of surrounding cells and has good biocompatibility.

[0003] The freeze-drying mold for decellularized matrix materials is a special mold for preparing freeze-dried products of decellularized matrix materials. However, when fixing the freeze-drying mold for decellularized matrix materials, it is necessary to repeatedly turn the bolts to fix the base plate and the pressure plate together. Although this connection method ensures the stability of the connection, the operation is cumbersome, and the bolts may slip after long-term use. For this reason, we propose a freeze-drying mold assembly for decellularized matrix materials. Utility Model Content

[0004] The purpose of the utility model is to provide a freeze-drying mold assembly for decellularized matrix materials to solve the problems raised by the above-mentioned background technology.

[0006] Preferably, the locking assembly includes an external spline, a spring, a second support member and an internal spline. The end of the worm gear away from the first support member is slidably connected to the external spline. The external spline is inserted into the outer sleeve of one end of the worm gear and the spring is arranged. The upper end of the external spline can be inserted into the second support member. The second support member is provided with the internal spline meshing with the external spline, and the external spline can be unlocked by an adjusting member.

[0007] Preferably, the adjusting member includes a first knob and a second knob, the first knob is installed at the top end of the external spline, and the top end of the first knob is rotatably connected to the second knob.

[0008] Preferably, the lifting assembly includes a worm wheel and a rack, the worm is meshed with the worm wheel, the worm wheel is rotatably connected to the first support member, and its side away from the worm is meshed with the rack, and the rack penetrates the first support member and is connected to the second clamping plate.

[0009] Preferably, two groups of first sliding rods are symmetrically mounted on the upper surface of the second clamping plate, and the first sliding rods penetrate the first supporting member and are slidably connected thereto.

[0010] Preferably, the first clamping plate is installed with four groups of second sliding rods, and the four groups of second sliding rods all pass through the second clamping plate and are slidably connected thereto.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model utilizes the rotation of the worm and cooperates with the lifting component to drive the second clamping plate to slide along the first support member, and adjusts its height so that it cooperates with the first clamping plate to clamp and press the decellularized matrix material, so that the decellularized matrix material is not easily deformed. At the same time, the locking component can be used to lock the worm to prevent it from rotating, thereby achieving stable clamping of the decellularized matrix material. Compared with the existing technology, the utility model is simple to use, is not prone to thread slippage, can maintain a stable clamping effect, and prevents the decellularized matrix material from deformation.

[0013] 2. The utility model drives the first knob and the outer spline to move by pressing the second knob, so that the outer spline is inserted into the worm and disengaged from the inner spline, and the spring is compressed at the same time. At this time, turning the first knob can drive the outer spline and the worm to rotate, which can drive the worm wheel to rotate, so that the rack moves accordingly, and the second clamping plate can be driven to rise and fall to adjust its height from the first clamping plate. Conversely, the second knob is released, the spring is reset, and the outer spline is pushed to rise and inserted into the inner spline. The second support member is used to limit the outer spline to prevent it from rotating, thereby locking the worm. In combination with the self-locking effect of the worm wheel and the worm, the locking effect can be improved to maintain the stability of the clamping of the decellularized matrix material.

[0023] In this embodiment, the rotation of the worm 4 and the lifting assembly can drive the second clamping plate 2 to slide along the first support member 3, and adjust its height so that it can cooperate with the first clamping plate 1 to clamp and press the decellularized matrix material, so that the decellularized matrix material is not easily deformed. At the same time, the locking assembly can be used to lock the worm 4 to prevent it from rotating, thereby achieving stable clamping of the decellularized matrix material. Compared with the existing technology, it is simple to use, less prone to thread slippage, and can maintain a stable clamping effect to prevent the decellularized matrix material from deformation.

[0024] Please refer to Figure 1-4As shown, the locking assembly includes an external spline 5, a spring 6, a second support member 7 and an internal spline 8. The end of the worm 4 away from the first support member 3 is slidably connected to the external spline 5. The external spline 5 is inserted into the external sleeve spring 6 at one end of the worm 4. The upper end of the external spline 5 can be inserted into the second support member 7. The second support member 7 is provided with an internal spline 8 meshing with the external spline 5. The external spline 5 can be unlocked by an adjusting member. The adjusting member includes a first knob 9 and a second knob 10. The first knob 9 is installed on the top of the external spline 5, and the top of the first knob 9 is rotatably connected to the second knob 10. The lifting assembly includes a worm wheel 11 and a rack 12. The worm 4 is meshed with the worm wheel 11, and the worm wheel 11 is rotatably connected to the first support member 3, and its side away from the worm 4 is meshed with the rack 12. The rack 12 penetrates the first support member 3 and is connected to the second clamping plate 2.

[0025] In this embodiment, by pressing the second knob 10, the first knob 9 and the external spline 5 are driven to move, so that the external spline 5 is inserted into the worm 4 and disengaged from the internal spline 8, and the spring 6 is compressed at the same time. At this time, rotating the first knob 9 can drive the external spline 5 and the worm 4 to rotate, which can drive the worm wheel 11 to rotate, so that the rack 12 moves accordingly, and the second clamping plate 2 can be driven to rise and fall, and its height from the first clamping plate 1 is adjusted. Conversely, the second knob 10 is released, the spring 6 is reset, and the external spline 5 is pushed to rise and insert the internal spline 8, and the second support member 7 is used to limit the external spline 5 to prevent it from rotating, thereby locking the worm 4. In combination with the self-locking effect of the worm wheel 11 and the worm 4, the locking effect can be improved to maintain the stability of the clamping of the decellularized matrix material.

[0028] Working principle: First, by pressing the second knob 10, the first knob 9 and the outer spline 5 are driven to move, so that the outer spline 5 is inserted into the worm 4 and disengaged from the inner spline 8, and the spring 6 is compressed at the same time. At this time, turning the first knob 9 can drive the outer spline 5 and the worm 4 to rotate, which can drive the worm wheel 11 to rotate, so that the rack 12 moves accordingly, and the second clamping plate 2 can be driven to rise and fall to adjust its height from the first clamping plate 1. Conversely, the second knob 10 is released, the spring 6 is reset, and the outer spline 5 is pushed to rise and insert the inner spline 8, and the second support member 7 is cooperated to limit the outer spline 5 to prevent it from rotating, thereby locking the worm 4. In combination with the self-locking effect of the worm wheel 11 and the worm 4, the locking effect can be improved to maintain the stability of the acellular matrix material clamping. When the second clamping plate 2 is lifted or lowered, the first sliding bar 13 can be driven to slide and lift along the first supporting member 3, and the second clamping plate 2 can slide and lift along the second sliding bar 14, which helps to improve the stability of the second clamping plate 2 when it is lifted or lowered.
