Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and more specifically, to a small drilling device for the production of bone implant materials. Background Technology

[0002] Bone implants are primarily used to repair bone defects or promote bone healing. Common types include autologous bone, allogeneic bone, xenogeneic bone, and synthetic bone. During the production of bone implants, a drilling device is required to drill holes at the implant placement sites. Existing drilling devices typically place the implant material to be drilled directly on a support platform. However, for some bone implants requiring tilted drilling, pliers are needed to clamp the implant material at an angle before drilling, making the process inconvenient. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a small drilling device for the production of bone implant materials, which has the advantage of being able to perform inclined drilling conveniently.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a small drilling device for bone implant material production, comprising a base plate, a drilling mechanism and a placement platform fixedly installed at the top of the base plate, a rotating plate rotatably connected to the middle of the drilling mechanism, a lifting block fixedly installed at the bottom of the rotating plate, a screw rotatably connected to the middle of the placement platform, a meshing block threadedly connected to the surface of the screw, and an extension plate fixedly installed on the right side of the placement platform.

[0005] As a preferred embodiment of this utility model, the drilling mechanism is located on the rear side of the placement platform, and a square groove is provided in the middle of the placement platform. The rotating plate and the meshing block are both movably connected in the square groove.

[0006] As a preferred embodiment of this utility model, the lifting block is a right-angled triangle, and the top left end of the engaging block is in contact with the bottom surface of the rotating plate.

[0007] As a preferred technical solution of this utility model, an installation hole is provided on the left side of the top of the placement platform, a plug shaft is inserted into the inner cavity of the installation hole, a limit plate is fixedly installed on the top of the plug shaft, and a locking plate is slidably connected to the top of the placement platform, the locking plate being "L" shaped.

[0008] As a preferred technical solution of this utility model, a fixing box is fixedly installed on the left end of the placement platform, a pressure plate is slidably connected to the inner cavity of the fixing box, an extension frame is fixedly installed on the top end of the pressure plate, a spring is fixedly installed on the top end of the pressure plate, fixing tubes are fixedly installed on both the front and rear sides of the top end of the placement platform, a moving shaft is slidably connected to the inner cavity of the fixing tube, and a clamp is fixedly installed on one end of the moving shaft that extends out of the fixing tube.

[0009] As a preferred embodiment of this utility model, the top end of the extension frame extends through and above the fixed box, and the top end of the extension frame is on the same horizontal plane as the top surface of the placement platform, and the top end of the spring is fixedly connected to the top end of the extension frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a rotatable screw to engage with a meshing block, can drive the meshing block to move to the right when the screw is rotated, thereby causing the meshing block to move to the right below the rotating plate and the lifting block. When the top of the meshing block contacts the bottom surface of the lifting block, the rotating plate can be pushed forward by the lifting block to tilt the rotating plate. At this time, the bone implant material placed on the rotating plate can be tilted and located below the drill bit of the drilling mechanism, thereby realizing convenient tilting drilling of the bone implant material.

[0012] 2. This utility model achieves automatic and rapid fixation of bone implant materials by moving the limiting plate downward during installation, which causes the extension frame to move downward, thereby squeezing the gas in the fixing box into the fixing tube and pushing the moving axis to move closer to the center of the placement platform. This allows the clamping plate to hold the bone implant material on both the front and back sides. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] like Figures 1 to 5 As shown, this utility model provides a small drilling device for the production of bone implant materials, including a base plate 1, a drilling mechanism 2 and a placement platform 3 fixedly installed at the top of the base plate 1, a rotating plate 4 rotatably connected to the middle of the drilling mechanism 2, a lifting block 5 fixedly installed at the bottom of the rotating plate 4, a screw 6 rotatably connected to the middle of the placement platform 3, a meshing block 7 threadedly connected to the surface of the screw 6, and an extension plate 8 fixedly installed on the right side of the placement platform 3.

[0021] By setting a rotatable screw 6 to mesh with a meshing block 7, when the screw 6 is rotated, the meshing block 7 can be driven to move to the right, thereby causing the meshing block 7 to move to the right below the rotating plate 4 and the lifting block 5. When the top of the meshing block 7 contacts the bottom surface of the lifting block 5, the rotating plate 4 can be pushed up by the lifting block 5 to tilt the rotating plate 4. At this time, the bone implant material placed on the rotating plate 4 can be tilted and located below the drill bit of the drilling mechanism 2, thereby realizing convenient tilting drilling of the bone implant material.

[0022] The punching mechanism 2 is located on the rear side of the placement platform 3. A square groove is provided in the middle of the placement platform 3, and the rotating plate 4 and the meshing block 7 are movably connected in the square groove.

[0023] The installation of the rotating plate 4 and the positioning of the moving meshing block 7 are achieved by setting a square groove, thus ensuring the stability of both.

[0024] Among them, the lifting block 5 is a right-angled triangle shape, and the top of the left end of the meshing block 7 is in contact with the bottom surface of the rotating plate 4.

[0025] The right end of the rotating plate 4 is supported by the meshing block 7 to prevent the rotating plate 4 from accidentally tipping over and to ensure stability in the drilling state. By setting the right-angle plate of the lifting block 5 downward, the lifting block 5 can be pushed up as a whole by the guide of the right-angle side when the meshing block 7 moves to the right. The extension plate 8 is set to support and guide the meshing block 7 when it extends out of the placement platform 3.

[0026] The top left side of the placement platform 3 has an installation hole 9, the inner cavity of the installation hole 9 is connected to a plug shaft 11, the top of the plug shaft 11 is fixedly installed with a limit plate 10, and the top of the placement platform 3 is slidably connected to a locking plate 16, which is "L" shaped.

[0027] By inserting the connector shaft 11 into different mounting holes 9, the distance between the limiting plate 10 and the rotating plate 4 can be changed, thereby changing the end position of the bone implant material. This allows for drilling at different lateral positions of the bone implant material. By setting the locking plate 16, after the limiting plate 10 is installed in place, the locking plate 16 can be slid forward and latched onto the top of the limiting plate 10 to fix the limiting plate 10 and prevent it from falling off.

[0028] Among them, a fixed box 12 is fixedly installed on the left end of the placement platform 3, a pressure plate 13 is slidably connected to the inner cavity of the fixed box 12, an extension frame 14 is fixedly installed on the top of the pressure plate 13, a spring 15 is fixedly installed on the top of the pressure plate 13, and fixed tubes 17 are fixedly installed on both the front and rear sides of the top of the placement platform 3. A movable shaft 18 is slidably connected to the inner cavity of the fixed tube 17, and a clamping plate 19 is fixedly installed on one end of the movable shaft 18 that extends out of the fixed tube 17.

[0029] When the limiting plate 10 is installed, the downward movement of the limiting plate 10 causes the extension frame 14 to move downward, thereby squeezing the gas in the fixing box 12 into the fixing tube 17, pushing the moving shaft 18 to move towards the side closer to the center of the placement platform 3, thereby causing the clamping plate 19 to clamp on the front and rear sides of the bone implant material, realizing automatic and rapid fixation of the bone implant material.

[0030] The top of the extension frame 14 extends through and above the fixing box 12, and the top of the extension frame 14 is on the same horizontal plane as the top surface of the placement platform 3. The top of the spring 15 is fixedly connected to the top of the extension frame 14.

[0031] By setting the spring 15, after the limiting plate 10 is removed, the spring 15, which is in a compressed state, pushes the extension frame 14 upward under the action of elasticity, thereby pulling the pressure plate 13 upward to draw back the gas in the fixing tube 17, causing the clamp 19 to move in the opposite direction, thus realizing the automatic unlocking of the bone implant material. Since the overall volume of the bone implant material is not large, the device is small in size and saves space.

[0032] Working principle and usage process of this utility model:

[0033] When in use, place the bone implant material on the rotating plate 4, and then rotate the screw 6 according to the required drilling angle. Through the engagement of the screw 6 and the engagement block 7, the engagement block 7 is driven to move to the right. When the top of the engagement block 7 contacts the lifting block 5, the right end of the rotating plate 4 can be lifted up as a whole, so that the rotating plate 4 is in an inclined state. At this time, the bone implant material is in an inclined state. The greater the distance that the engagement block 7 moves to the right, the greater the inclination angle of the rotating plate 4.

[0034] Then, according to the drilling position, the limiting plate 10 is installed on the corresponding mounting hole 9 through the plug shaft 11. During installation, the limiting plate 10 presses down the extension frame 14, thereby causing the pressure plate 13 to move downward in the fixing box 12, squeezing the air in the fixing box 12 into the fixing tube 17 through the connected pipe, pushing the moving shaft 18 and the clamping plate 19 closer to the bone implant material, thereby clamping and fixing the bone implant material.

[0035] Then, the drilling mechanism 2 is activated to drill holes in the bone implant material. After drilling is completed, the limiting plate 10 is pulled out first. At this time, the spring 15 pushes the extension frame 14 and the pressure plate 13 upward, thereby drawing back the gas in the fixation tube 17 and unlocking the bone implant material.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
