Description

Technical Field

[0001] This utility model relates to the field of bone substitute material detection technology, specifically to a morphology detection device for calcium phosphate bone material. Background Technology

[0002] With the development of biomedical engineering, implant materials are increasingly widely used in the medical field. Among them, calcium phosphate bone material is a commonly used biomaterial, widely applied in bone repair and bone replacement. To ensure the biocompatibility, mechanical properties, safety, and effectiveness of implant materials, it is essential to perform morphological testing on the molded calcium phosphate bone material. The morphological testing scope of calcium phosphate bone material mainly includes the microstructure, roughness, and porosity of the material surface.

[0003] The equipment used for morphological inspection of calcium phosphate bone materials mainly includes a control module, a scanning and detection module, and a detection stage. The core of the scanning and detection module is a microscope, which is used to scan and observe the surface of the calcium phosphate bone material to obtain its morphological information. However, because the outer contour structure of calcium phosphate bone materials needs to be designed according to usage requirements, the molded calcium phosphate bone materials are mostly irregular in structure, lightweight, and small in size. Directly placing them on the detection stage cannot ensure observation stability. Conventional clamping tools, when used to clamp calcium phosphate bone materials of different shapes, cannot simultaneously meet the requirements of clamping stability, preventing pressure damage, and minimizing obstruction. Therefore, this invention proposes a morphological inspection device for calcium phosphate bone materials. Utility Model Content

[0004] The purpose of this invention is to provide a morphology detection device for calcium phosphate bone materials in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] This invention provides a morphology detection device for calcium phosphate bone materials, including a frame, a scanning electron microscope, a gimbal, a control unit, and a flexible detection stage for fixing and placing the calcium phosphate bone materials. The flexible detection stage includes an upper clamping member and a lower clamping member with adjustable vertical spacing. The upper clamping member includes several longitudinal pressure ropes, and the lower clamping member includes several transverse pressure ropes. The longitudinal and transverse pressure ropes are used to adapt to the outer contour of calcium phosphate bone materials of different shapes through stretching and deformation to clamp the calcium phosphate bone materials.

[0007] As a further optimization of this utility model, the frame includes a base, a sliding frame slidably connected to the base, and a suspension frame disposed on the sliding frame. The scanning electron microscope and the control unit are both disposed on the suspension frame, and the scanning electron microscope is movably connected to the suspension frame through a gimbal.

[0008] As a further optimization of this utility model, the upper clamping member also includes horizontal bars on both sides of the longitudinal pressure rope, the lower clamping member also includes vertical bars on both sides of the transverse pressure rope, the base is provided with a support frame for supporting the lower clamping member, and the support frame is provided with a lifting component for positioning the upper clamping member at four corners.

[0009] As a further optimization of this utility model, the lifting assembly includes a positioning sleeve on the support frame, a lifting rod passing through the positioning sleeve, and a positioning pin on the positioning sleeve. The lifting rod has a plurality of insertion holes arranged in a linear array to cooperate with the positioning pin.

[0010] As a further optimization of this utility model, one end of the crossbar is rotatably connected to the lifting rod at the corresponding position, and the other end is detachably snapped into the lifting rod at the corresponding position through a retaining ring.

[0011] As a further optimization of this utility model, the crossbar is provided with a mounting seat, and the lifting rod at the corresponding position is provided with a mounting pin that can be rotatably engaged with the mounting seat, and the longitudinal bar is detachably engaged with the support frame.

[0012] As a further optimization of this utility model, the crossbar includes a connecting rod and a support rod. The near ends of the connecting rod and the support rod are rotatably connected by a torsion spring, and the pivot is perpendicular to the central axis of the mounting base.

[0013] The beneficial effects of this utility model are as follows:

[0014] The morphology detection device for calcium phosphate bone materials proposed in this utility model, through the cooperation of longitudinal and transverse pressure ropes, allows for the effective clamping of calcium phosphate bone materials by simply adjusting the vertical spacing between the longitudinal and transverse pressure ropes. Both the longitudinal and transverse pressure ropes can adapt to the outer contour of the calcium phosphate bone material, enabling this flexible detection stage to stably clamp calcium phosphate bone materials of different sizes and outer contours without the need for additional tools. It has a wide range of applications and high clamping stability. Furthermore, since both the longitudinal and transverse pressure ropes are thin ropes, they minimize obstruction of the calcium phosphate bone material, facilitating large-scale surface morphology scanning and detection after clamping. This comprehensively improves the convenience and detection effect of morphology detection for calcium phosphate bone materials. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1-5 As shown, the morphology detection device for calcium phosphate bone material in this embodiment includes a frame, a scanning electron microscope 4, a gimbal 5, a control unit 6, and a flexible detection stage for fixing and placing the calcium phosphate bone material. The scanning electron microscope 4 is preferably a type equipped with a camera, which can be connected to a display system to observe, export, and record the scanning results. The flexible detection stage includes an upper clamping member and a lower clamping member with adjustable vertical spacing. The upper clamping member includes several longitudinal pressure ropes 9, and the lower clamping member includes several transverse pressure ropes 13. The longitudinal pressure ropes 9 and transverse pressure ropes 13 are used to adapt to the outer contour of calcium phosphate bone material of different shapes by stretching and deforming in order to clamp the calcium phosphate bone material.

[0024] When using this morphology detection device to detect the surface morphology of calcium phosphate bone material, simply place the formed calcium phosphate bone material on the lower clamping member. The supporting surface formed by the transverse pressure rope 13 can support the calcium phosphate bone material. Then, adjust the upper and lower clamping members to gradually approach each other, and the longitudinal pressure rope 9 will gradually approach the calcium phosphate bone material. When the longitudinal pressure rope 9 contacts the calcium phosphate bone material and continues to approach the transverse pressure rope 13, both the longitudinal pressure rope 9 and the transverse pressure rope 13 will deform due to pressure and conform to the outer contour of the calcium phosphate bone material. This achieves the effect of clamping and stabilizing the calcium phosphate bone material. Subsequently, the scanning electron microscope 4 can scan the fixed calcium phosphate bone material to obtain the surface morphology information of the calcium phosphate bone material.

[0025] It should be emphasized that, on the one hand, the longitudinal pressure rope 9 and the transverse pressure rope 13 are preferably made of elastic silicone rope, which is less likely to damage the calcium phosphate bone material. When clamping and fixing the calcium phosphate bone material, it is not necessary to adjust the longitudinal pressure rope 9 and the transverse pressure rope 13 to the point of contact. The vertical distance between the longitudinal pressure rope 9 and the transverse pressure rope 13 is adjusted according to the size and outer contour structure of the calcium phosphate bone material, as long as the calcium phosphate bone material can be stably clamped. On the other hand, when it is necessary to perform a comprehensive scanning observation of the surface of the calcium phosphate bone material, it is only necessary to adjust the clamping angle of the calcium phosphate bone material multiple times and repeat the scanning.

[0026] Preferably, the frame includes a base 1, a sliding frame 2 slidably connected to the base 1, and a suspension frame 3 disposed on the sliding frame 2. An anti-slip layer can be provided on the outer surface of the sliding frame 2 or in the sliding groove on the base 1 to prevent the sliding frame 2 from sliding randomly without external force. The scanning electron microscope 4 and the control unit 6 are both disposed on the suspension frame 3. The scanning electron microscope 4 is movably connected to the suspension frame 3 through a gimbal 5. The gimbal 5 can drive the scanning electron microscope 4 to perform multi-angle scanning of calcium phosphate bone material.

[0027] Preferably, the upper clamping member further includes horizontal bars 8 on both sides of the longitudinal pressure rope 9, and the lower clamping member further includes vertical bars 12 on both sides of the horizontal pressure rope 13. The base 1 is provided with a support frame 7 for supporting the lower clamping member, and the support frame 7 is provided with a lifting assembly 11 for positioning the upper clamping member at four corners.

[0028] The lifting assembly 11 includes a positioning sleeve 1101 mounted on the support frame 7, a lifting rod 1102 passing through the positioning sleeve 1101, and a positioning pin 1103 mounted on the positioning sleeve 1101. The lifting rod 1102 has several insertion holes arranged in a linear array to cooperate with the positioning pin 1103.

[0029] Adjust the position of the insertion hole on the lifting rod 1102 that aligns with the positioning sleeve 1101, and insert the positioning pin 1103 for vertical fixation to adjust the height of the upper clamping component.

[0030] Preferably, one end of the crossbar 8 is rotatably connected to the lifting rod 1102 at the corresponding position, and the other end is detachably snapped into the lifting rod 1102 at the corresponding position through the retaining ring 10. This allows the operator to hold calcium phosphate bone material without frequently adjusting the height of the upper clamping part to allow for a sufficiently large manual control space. The operator can simply flip the upper clamping part to the side, making the operation more convenient and flexible.

[0031] Preferably, the crossbar 8 is provided with a mounting seat 14, and the corresponding lifting rod 1102 is provided with a mounting pin 15 that can be rotatably engaged with the mounting seat 14. The longitudinal rod 12 is detachably engaged with the support frame 7. The mounting pin 15 is preferably a spring pin, so that both the upper clamping part and the lower clamping part can be detached, which makes it convenient to select different models of upper clamping parts and lower clamping parts according to the size of the calcium phosphate bone material. The different models include different sizes and different fineness and distribution density of the longitudinal pressure rope 9 and the transverse pressure rope 13.

[0032] Preferably, the crossbar 8 includes a connecting rod 801 and a support rod 802. The proximal ends of the connecting rod 801 and the support rod 802 are rotatably connected by a torsion spring, and the pivot is perpendicular to the central axis of the mounting base 14. This allows the distal end of the support rod 802 to move at multiple angles, making it convenient to move it into and out of the retaining ring 10.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
