Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for accurately cutting a barrier membrane for oral implant guided bone regeneration. Background Art

[0002] Oral implant restoration surgery is one of the preferred treatment options for patients with missing teeth, and successful oral implant restoration requires that the patient's alveolar bone has sufficient bone quality and bone volume. However, due to trauma, tumor resection, inflammation and other reasons, insufficient bone volume in the implant area has become the primary reason for implant failure or implant failure. In order to restore the alveolar bone tissue in the bone defect area and improve the success rate of implant restoration, guided bone regeneration technology is widely used in oral implant surgery.

[0003] Guided bone regeneration technology uses biomaterials to artificially create a microporous biomembrane, which acts as a barrier to prevent fibroblasts and epithelial cells in soft tissue from growing into the bone defect area, protect the stability of blood clots, maintain the gap filled by blood clots, and allow cells with bone generation ability to slowly enter the bone defect area to repair the bone defect. This biomembrane, the guided bone regeneration barrier membrane, plays a vital role in oral implant surgery. Since oral implant surgery requires high precision, the guided bone regeneration barrier membrane needs to be accurately cut to ensure that it can completely cover the bone defect area while avoiding damage to surrounding healthy tissues.

[0004] The existing precise cutting devices for oral implant guided bone regeneration barrier membranes have obvious deficiencies in adapting to the cutting requirements of different sizes and shapes, which results in the need to frequently replace or adjust the device during the cutting process, greatly reducing the cutting efficiency and significantly increasing the complexity and difficulty of the operation.

The fixing plate 201 is fixedly installed on both sides of the top of the fixing frame 5, and the guide rail 202 is fixedly installed on both ends of the fixing plate 201. The first screw rod 203 is threadedly connected to the middle part of the fixing plate 201. The first motor 204 is fixedly connected to one end of the first screw rod 203 and is fixedly connected to the fixing plate 201.

The top of the connecting rod 206 and the side of the fixing frame 5 are both provided with a scale 13.

[0021] Specifically, the longitudinal adjustment mechanism 3 is fixedly installed at the bottom of the connecting rod 206, and the longitudinal adjustment mechanism 3 includes a side plate 301, a first guide rod 302, a second screw rod 303, a second motor 304 and a moving block 305. The side plate 301 is fixedly installed at the bottom of both ends of the connecting rod 206, the first guide rod 302 is fixedly installed on the inner side of the side plate 301, the second screw rod 303 is threadedly connected to the inside of the side plate 301, the first guide rod 302 is located above the second screw rod 303, the second motor 304 is fixedly connected to one end of the second screw rod 303, and is fixedly connected to the side plate 301, the moving block 305 is threadedly connected to the outer side of the second screw rod 303, and is slidably installed on the outer side of the first guide rod 302.

[0022] In this embodiment: the base 1 serves as the basic support structure of the entire cutting device to ensure the stability and reliability of the device. The lateral adjustment mechanism 2 is responsible for accurately adjusting the cutting position in the horizontal direction. The fixed plate 201 is fixedly installed on the top of the fixed frame 5 to provide an installation position for the guide rail 202 and the first screw rod 203. The guide rail 202 ensures that the slider 205 slides stably in the horizontal direction. The first motor 204 provides power for the first screw rod 203 to achieve automatic adjustment.

Mechanism 3 is responsible for accurately adjusting the cutting position in the longitudinal direction. The side plate 301 is fixedly installed at the bottom of the connecting rod 206 to provide an installation position for the first guide rod 302 and the second screw rod 303. The second motor 304 provides power for the second screw rod 303 to realize automatic adjustment. The rotation of the second screw rod 303 drives the moving block 305 to move vertically on the first guide rod 302. The moving block 305 slides on the first guide rod 302 and is connected to the electric push rod 6 to realize the longitudinal movement of the cutting position. The first guide rod 302 is used to ensure that the moving block 305 slides stably in the longitudinal direction. Through the setting of the scale 13, the user can more intuitively and accurately grasp and identify the cutting size of the regenerated barrier membrane, thereby ensuring the accuracy and efficiency of the operation.

[0023] Specifically, an electric push rod 6 is fixedly installed on the bottom of the moving block 305, a connecting plate 7 is fixedly installed on the bottom of the electric push rod 6, a laser measuring instrument 8 is fixedly installed on the bottom of one end of the connecting plate 7, a tool 9 is fixedly installed on the bottom of the other end of the connecting plate 7, a fixed block 10 is fixedly installed on the side of the moving block 305, a guide rod sleeve 11 is fixedly installed on the bottom of the fixed block 10, a second guide rod 12 is slidably installed in the inner cavity of the guide rod sleeve 11, and the bottom of the second guide rod 12 is fixedly connected to the connecting plate 7.

[0024] In this embodiment: the electric push rod 6 is used to provide power to move the connecting plate 7 in the vertical direction. The connecting plate 7 serves as the installation base for the laser measuring instrument 8 and the tool 9. The laser measuring instrument 8 is used to accurately detect the cutting position to ensure the accuracy of cutting. The tool 9 is used for the actual cutting operation and performs accurate cutting according to the detection result of the laser measuring instrument 8. The fixed block 10 provides an installation position for the guide rod sleeve 11 and ensures that it is stably connected to the moving block 305. The guide rod sleeve 11 provides a sliding track for the second guide rod 12 to ensure the stable sliding of the second guide rod 12 in the vertical direction. The second guide rod 12 provides vertical guidance for the connecting plate 7 to ensure that the vertical movement of the cutting tool is accurate.

[0025] Specifically, the clamping mechanism 4 is fixedly installed on both sides of the top of the base 1, and the clamping mechanism 4 includes a mounting plate 401, a support plate 402, a bottom plate 403, a top plate 404, a threaded rod 405, a turntable 406, a clamping block 407 and a rubber pad 408. The mounting plate 401 is fixedly installed on the top of the base 1 by bolts, the support plate 402 is fixedly installed on the top of the mounting plate 401, the bottom plate 403 and the top plate 404 are both fixedly installed on the side of the support plate 402, and the top plate 404 is located above the bottom plate 403, the threaded rod 405 is threadedly connected to the center of the top plate 404, the turntable 406 is fixedly installed on the top of the threaded rod 405, the clamping block 407 is fixedly connected to the bottom of the threaded rod 405, and the rubber pad 408 is fixedly installed on the bottom of the clamping block 407.

[0026] In this embodiment: the oral implant guided bone regeneration barrier membrane to be cut can be firmly fixed by the clamping mechanism 4 to ensure that it will not move or deform during the cutting process, thereby improving the accuracy and stability of the cutting. The mounting plate 401 is fixed to the top of the base 1 by bolts to ensure the stability of the clamping mechanism 4 during use. The bottom plate 403 and the top plate 404 together constitute a clamping space for fixing the material to be cut. The setting of the turntable 406 is convenient for the user to manually rotate the threaded rod 405. The rotating threaded rod 405 drives the clamping block 407 to move up and down to adjust the clamping force. The rubber pad 408 increases the friction between the clamping block 407 and the material to prevent sliding, while protecting the surface of the material from being clamped.

[0027] The working principle and use process of this utility model:

[0028] The oral implant guided bone regeneration barrier membrane to be cut is placed in the clamping mechanism 4, and the position of the clamping block 407 is adjusted by rotating the turntable 406, so that the clamping block 407 firmly clamps the material through the rubber pad 408, the equipment is started, and the initialization settings are performed, including the calibration of the laser measuring instrument 8 and the setting of the cutting parameters. The rotation of the first motor 204 is controlled by the control system to drive the first screw rod 203 to rotate, thereby driving the slider 205 to move horizontally on the guide rail 202. Since the connecting rod 206 connects the two sliders 205, the two sliders 205 move synchronously, thereby ensuring the precise adjustment of the cutting position in the horizontal direction. The rotation of the second motor 304 is controlled by the control system to drive the second screw rod 303 to rotate, thereby driving the moving block 305 to move on the first guide rod 302. The movement of the moving block 305 drives the electric push rod 6, the connecting plate 7, the laser measuring instrument 8 and the tool 9 to move in the horizontal direction, thereby realizing the precise adjustment of the cutting position in the longitudinal direction. Therefore, by precisely and synchronously controlling the operation of the first motor 204 and the second motor 304, the movement path of the tool 9 can be changed into a curved motion, thereby realizing precise curved cutting of the guided bone regeneration barrier membrane material, and making the cut material shape more precise and smooth. The laser measuring instrument 8 is driven by the electric push rod 6 and descends to a position close to the surface of the material to be cut, and accurately detects the cutting position. The control system calculates the precise cutting position according to the detection data of the laser measuring instrument 8, and adjusts the position of the tool 9. After the cutting position is determined, the electric push rod 6 pushes the connecting plate 7 and the tool 9 thereunder to descend, so that the tool 9 cuts the material. During the cutting process, the second guide rod 12 slides in the guide rod sleeve 11 to ensure the stable movement of the cutting tool in the vertical direction. After the cutting is completed, the electric push rod 6 drives the tool 9 to rise and reset, and the laser measuring instrument 8 also returns to the initial position. The guided bone regeneration barrier membrane can be replaced as needed for the next cutting operation.
