Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bone graft material forming and cutting device. Background Technology

[0002] Bone grafts are biomedical materials widely used in orthopedics, dentistry, and plastic surgery, primarily for repairing bone defects caused by trauma, tumor resection, or congenital defects. Based on their source, bone grafts can be categorized into three main types: autologous bone, allogeneic bone, and synthetic bone. With advancements in medical technology, the requirements for the processing precision of bone grafts are becoming increasingly stringent, especially regarding shape fit, surface smoothness, and dimensional consistency. Therefore, the cutting process is particularly crucial in the molding and subsequent processing of bone grafts, as its precision directly impacts the clinical efficacy of the material.

[0003] Currently, traditional bone graft material cutting mostly employs manual tools or conventional mechanical cutting equipment, which suffers from problems such as low cutting precision, uneven surfaces, and susceptibility to microcracks, affecting the material's mechanical properties and biocompatibility. Furthermore, traditional cutting methods are typically contact-based, easily introducing contamination or causing material fragmentation, failing to meet the demands of modern medicine for high-precision, sterile processing. Therefore, there is an urgent need for a device capable of high-precision, non-contact cutting to improve the processing quality and safety of bone graft materials and meet the requirements for fine material processing in clinical applications.

[0004] Therefore, it is necessary to design a bone graft material molding and cutting device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional cutting methods, which are usually contact-based operations, easily introduce contamination or cause material breakage, and are difficult to meet the requirements of modern medicine for high precision and sterile processing, this utility model provides a bone graft material forming and cutting device.

[0006] A bone graft material molding and cutting device includes a shell, an observation plate, a sealing door, a guide plate, a loading frame, a first electric slide rail, a first connecting block, a second electric slide rail, a second connecting block, a third electric slide rail, a third connecting block, a laser scalpel, and a controller. The shell has a hollow cavity extending from the left side to the center. An observation plate is installed on the front of the shell. A sealing door is rotatably connected to the left side of the shell. Guide plates are symmetrically fixed to the bottom of the cavity. A loading frame is slidably connected above the guide plates. First electric slide rails are symmetrically installed on the rear sidewall of the cavity. A first connecting block is slidably connected to each first electric slide rail. A second electric slide rail is fixedly connected to each of the two first connecting blocks. A second connecting block is slidably connected to each of the second electric slide rails. A third electric slide rail is fixedly connected between the second connecting blocks. A third connecting block is slidably connected to the front of the third electric slide rail. A laser scalpel is fixedly connected to the third connecting block. A controller is located on the front of the shell. The first electric slide rail, the second electric slide rail, the third electric slide rail, and the laser scalpel are all electrically connected to the controller.

[0007] Furthermore, it is particularly preferable that the observation plate is made of a transparent material.

[0008] Furthermore, it is particularly preferred that the outer casing also includes a sponge pad, with the sponge pad located on the right side of the cavity.

[0009] Furthermore, it is particularly preferred that the device also includes a condenser and an electric fan, with the condenser installed on the inner bottom right side of the housing and the electric fan located on the left side of the condenser, near the sponge pad.

[0010] In addition, it is particularly preferred that it also includes anti-slip pads, with multiple anti-slip pads provided on the bottom of the outer casing.

[0011] In addition, it is particularly preferred that multiple heat dissipation holes are provided on the top rear side of the housing.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model achieves high-precision, non-contact cutting of bone graft materials by setting up a three-dimensional motion system consisting of a first, second, and third electric slide rail, and cooperating with a controller to realize automated control. The enclosed design reduces the risk of contamination that may arise from traditional mechanical cutting, ensuring the quality and safety of the materials.

[0014] 2. This invention provides cushioning protection by placing a sponge pad on the right side of the outer shell cavity when the loading frame is pushed in, effectively preventing the loading frame and its internal materials from being impacted or damaged during operation. This measure is particularly suitable for handling fragile or high-precision bone graft materials, greatly improving the safety and reliability of the equipment.

[0015] 3. This utility model achieves the effect of maintaining a stable operating temperature inside the cavity by integrating temperature control components such as a condenser, electric fan, and heat dissipation holes. This not only helps maintain the stability of equipment operation and avoids material deformation or equipment failure caused by high temperatures, but also extends the service life of the equipment and ensures the reliability of long-term continuous operation.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] Example: A bone graft material molding and cutting device, such as Figures 1-3As shown, the device includes a housing 1, an observation plate 2, a sealing door 3, a guide plate 4, a loading frame 5, a first electric slide rail 6, a first connecting block 601, a second electric slide rail 7, a second connecting block 701, a third electric slide rail 9, a third connecting block 10, a laser scalpel 11, and a controller 12. The housing 1 has a hollow cavity from left to center to accommodate the cutting components and processing area. A transparent observation plate 2 is installed on the front of the housing 1 to allow operators to monitor the internal working status in real time. A rotatable sealing door 3 is located on the left side of the housing 1 for loading and unloading the loading frame 5, ensuring a sealed processing environment, preventing dust leakage, and improving safety. Guide plates 4 are symmetrically connected to the bottom of the cavity by bolts. The loading frame 5 is slidably connected above the guide plates 4 to carry the bone graft material to be processed. First electric slide rails 6 are symmetrically installed on the rear side wall of the cavity. A first connecting block 601 is slidably connected to rail 6. Two first connecting blocks 601 are each connected to a second electric slide rail 7 by bolts. Two second connecting blocks 701 are slidably connected to each second electric slide rail 7. A third electric slide rail 9 is connected between the second connecting blocks 701 by bolts. A third connecting block 10 is slidably connected to the front side of the third electric slide rail 9. A laser scalpel 11 is connected to the third connecting block 10 by bolts, realizing non-contact, high-precision cutting of bone graft materials. The laser scalpel 11 moves precisely in the X, Y, and Z directions through the first electric slide rail 6, the second electric slide rail 7, and the third electric slide rail 9, respectively, to achieve precise cutting of bone graft materials. A controller 12 is set on the front side of the outer shell 1. The first electric slide rail 6, the second electric slide rail 7, the third electric slide rail 9, and the laser scalpel 11 are all electrically connected to the controller 12 to realize automated cutting control.

[0022] like Figures 1-4 As shown, it also includes a sponge pad 15, a condenser 13, an electric fan 14, and an anti-slip pad 16. The sponge pad 15 is provided on the right side of the cavity of the outer casing 1 to provide cushioning when the loading frame 5 is pushed in, protecting the material from impact. The condenser 13 is installed on the bottom right side of the outer casing 1. The electric fan 14 is located on the left side of the condenser 13, close to the sponge pad 15, to maintain a stable temperature inside the cavity and prevent material deformation or equipment failure due to high temperature. Multiple anti-slip pads 16 are provided on the bottom of the outer casing 1 to enhance the stability of the device and prevent movement or vibration from affecting the cutting accuracy. Multiple heat dissipation holes 17 are provided on the top rear side of the outer casing 1 to effectively dissipate heat and ensure the stability of the equipment during long-term operation.

[0023] When using this bone graft material forming and cutting device, the operator puts the bone graft material to be processed into the loading frame 5 through the sealed door 3 on the left side of the outer shell 1, and pushes it into the cavity to the guide plate 4 for positioning and fixation. To prevent impact during the pushing process, a sponge pad 15 is provided on the right side of the cavity to provide cushioning protection.

[0024] After the sealing door 3 is closed, the cutting path, speed and laser power are set by the controller 12 on the front of the outer shell 1. After the system is started, the controller 12 coordinates the work of each component. The first electric slide rail 6 drives the first connecting block 601 to move up and down along the cavity. The second electric slide rail 7 controls the forward and backward displacement of the cutting mechanism. The third electric slide rail 9 controls the lateral movement of the laser blade 11. The three sets of slide rails work together to enable the laser blade 11 to run precisely along the preset trajectory in three-dimensional space to perform non-contact cutting of bone graft materials.

[0025] During the cutting process, the operator can monitor the processing status in real time through the front observation panel 2. To ensure stable operation of the equipment, the condenser 13, in conjunction with the electric fan 14, regulates the temperature inside the cavity to prevent high temperatures from affecting material properties or equipment stability. Meanwhile, the heat dissipation holes 17 on the top assist in heat dissipation, ensuring the reliability of the entire machine during long-term continuous operation. The anti-slip pads 16 on the bottom effectively improve the stability of the equipment and prevent cutting errors caused by vibration.

[0026] The entire device achieves efficient and precise cutting of bone graft materials through modular automatic control, improving processing efficiency and finished product quality, and has good practicality and safety.
