Description

Technical Field

[0001] This invention belongs to the technical field of dental implant testing equipment, and more specifically, relates to an implant stability testing device. Background Technology

[0002] The implant is inserted into a pre-prepared bone cavity, as described in (Chinese Utility Model Patent; Publication No.: CN220109870U; Subject Title: A Hole-Shaped Structure, Implant, and Dental Implant Apparatus; Publication Date: 2023.12.01) or (Chinese Invention Patent; Publication No.: CN118662262A; Subject Title: A Dental Implant System; Publication Date: 2024.09.20). The abutment for mounting the crown is inserted and fixed within the top cavity of the implant.

[0003] During the healing process, the surrounding bone tissue integrates with the implant surface. Once the integration is strong enough, the prosthesis can be attached to the implant. This type of implant is commonly used in dentistry and orthopedic surgery.

[0004] Since the strength of the bond between the implant and the bone tissue determines whether a prosthesis can be installed, assessing this bond is crucial. Currently, X-rays are primarily used to assess osseointegration, but this technique only observes the bone quality around the implant and assesses the degree of osseointegration based on that information. This method is highly dependent on the clinician's experience and has a significant margin of error. Therefore, there is an urgent clinical need for a precise method or device to assess the strength of the bond between the implant and the bone tissue. Summary of the Invention

[0005] The purpose of this invention is to provide an implant stability testing device to solve the technical problem in the prior art that it is very difficult to clinically test the degree of firmness between bone tissue and implant.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an implant stability detection device, comprising: a handle, an impactor, an impact rod, and a drive mechanism; The impact-bearing component is used for detachable fixation to the implant; The handle has a sliding channel extending in a first direction; the impact rod is slidably disposed within the sliding channel; The two ends of the impact rod are the impact end and the traction end, respectively; The drive mechanism is mounted on the handle; the drive mechanism is used to drive the impact rod to slide so that the impact end extends a predetermined distance outside the sliding channel and impacts the object to be impacted before retracting back into the sliding channel.

[0007] Furthermore, the drive mechanism includes: an elastic reset mechanism and a traction mechanism; The elastic reset mechanism is used to restore the impact rod to the equilibrium position when the external force is removed; the impact rod has an extended position and a retracted position on both sides of the sliding channel relative to the equilibrium position; The traction mechanism is used to pull the traction end and pull the impact rod to the retracted position before releasing it; When the impact rod is pulled to the retracted position and released, the impact rod moves toward the extended position under the action of the elastic reset mechanism, and after the impact rod reaches the extended position, it returns under the action of the elastic reset mechanism and finally stays at the equilibrium position. When the impact rod is in the extended position, the impact end extends a predetermined distance outside the sliding channel; when the impact rod is in either the balanced position or the retracted position, the impact end is located inside the sliding channel.

[0008] Furthermore, the elastic reset mechanism includes: a first stop wall, a second stop wall, a first plate, a second plate, an elastic pad, and a columnar spring; The first stop wall, the elastic pad, the first plate, the second plate, the columnar spring, and the second stop wall are arranged sequentially along the extension direction of the sliding channel; Both the first stop wall and the second stop wall are disposed on the inner wall of the sliding channel; both the first plate and the second plate are disposed on the outer surface of the impact rod. The elastic pad is disposed between the first plate and the first stop wall; the columnar spring is clamped between the second plate and the second stop wall; When the traction mechanism pulls the impact rod to the retracted position, the column spring is compressed to store energy; When the traction mechanism releases the impact rod in the retracted position, the columnar spring drives the impact rod to move toward the extended position via the second plate, and the first plate can compress the elastic pad when it contacts the elastic pad until the impact rod moves to the extended position; During the process of restoring deformation, the elastic pad works together with the columnar spring to adjust the position of the impact rod so that the impact rod eventually returns to the equilibrium position.

[0009] Furthermore, The traction mechanism includes: a driver, a wheel, and a lever; The rotating wheel is rotatably mounted on the handle, and the driver is connected to the rotating wheel for transmission.

The lever is mounted on the rotating wheel and rotates with the rotating wheel. The lever is parallel to and spaced apart from the axis of the rotating wheel. The traction end is provided with a hook. The hook has a hanging rod extending along a second direction. The hanging rod is perpendicular to the first direction and the axis of the rotating wheel, respectively. During the unidirectional rotation of the wheel, when the wheel rotates from the second angle to the avoidance angle range between the first angle and the second angle, the lever avoids the movement path of the hanging rod. During the unidirectional rotation of the wheel, when the impact rod is at the equilibrium position and the wheel rotates to the first angle, the lever is screwed into the hook and contacts the hanging rod; as the wheel continues to rotate from the first angle to the second angle, the hanging rod is located on the movement path of the lever, and the lever pulls the impact rod to the retracted position through the hanging rod.

[0027] In one embodiment, the sliding channel 11 is a cavity or groove.

[0028] In one embodiment, the impactor 5 and the implant 6 are fixedly connected by bolts 73.

[0029] In one embodiment, the top of the implant 6 has a conical cavity, and the bottom of the impactor 5 has a cone-shaped body that fits against the inner wall of the conical cavity.

When the impact rod 2 in the retracted position is released by the traction mechanism 32, the impact rod 2 moves from the retracted position to the equilibrium position under the reset force of the elastic reset mechanism 31. After the impact rod 2 passes the equilibrium position, it can reach the extended position. When the impact rod 2 reaches the extended position, the impact end 21 can move to a predetermined distance outside the sliding channel 11 and impact the object to be impacted 5.

[0033] In one embodiment, the traction mechanism 32 can be connected to the traction end 22 by clamping. After the traction mechanism 32 releases the clamp of the traction end 22, the impact rod 2 can be released.

[0034] Further, please refer to Figures 1 to 11As a specific embodiment of the implant stability detection device provided by the present invention, the elastic reset mechanism 31 includes: a first stop wall 311, a second stop wall 312, a first plate 3131, a second plate 3132, an elastic pad 314, and a columnar spring 315; the first stop wall 311, the elastic pad 314, the first plate 3131, the second plate 3132, the columnar spring 315, and the second stop wall 312 are arranged sequentially along the extension direction of the sliding channel 11; the first stop wall 311 and the second stop wall 312 are both disposed on the inner wall of the sliding channel 11; the first plate 3131 and the second plate 3132 are both disposed on the outer surface of the impact rod 2; the elastic pad 314 is disposed on the first Between plate 3131 and the first stop wall 311; a columnar spring 315 is clamped between the second plate 3132 and the second stop wall 312; when the traction mechanism 32 pulls the impact rod 2 to the retracted position, the columnar spring 315 is compressed and stores energy; when the traction mechanism 32 releases the impact rod 2 in the retracted position, the columnar spring 315 drives the impact rod 2 to move towards the extended position via the second plate 3132, and when the first plate 3131 contacts the elastic pad 314, it can compress the elastic pad 314 until the impact rod 2 moves to the extended position; during the process of restoring deformation, the elastic pad 314, together with the columnar spring 315, adjusts the position of the impact rod 2 so that the impact rod 2 finally returns to the equilibrium position. Thus, when the traction mechanism 32 pulls the impact rod 2 to the retracted position, the columnar spring 315 is compressed and stores energy; when the traction mechanism 32 releases the impact rod 2 from the retracted position, the columnar spring 315 can drive the impact rod 2 to move towards the extended position through the second plate 3132; when the first plate 3131 contacts the elastic pad 314, it can compress the elastic pad 314, and the elastic pad 314 will apply a reverse thrust to the impact rod 2 through the first plate 3131 to decelerate the impact rod 2 until the impact rod 2 moves to the extended position and then begins to move in the opposite direction to the equilibrium position; in addition, the elastic pad 314 can also play a buffering role.

[0035] In one embodiment, the elastic pad 314 is a silicone pad or a rubber pad.

[0036] In one embodiment, when the impact rod 2 is in the retracted position, the first plate 3131 and the elastic pad 314 are spaced apart from each other.

[0037] Further, please refer to Figures 1 to 11As a specific embodiment of the implant stability detection device provided by the present invention, the traction mechanism 32 includes: a driver 321, a rotating wheel 322, and a lever 323; the rotating wheel 322 is rotatably mounted on the handle 1, and the driver 321 is connected to the rotating wheel 322 in a transmission manner, the driver 321 being used to drive the rotating wheel 322 to rotate unidirectionally in a predetermined direction; the axis of the rotating wheel 322 is perpendicular to the first direction L1; the lever 323 is mounted on the rotating wheel 322 and rotates with the rotating wheel 322, the lever 323 being parallel to and spaced apart from the axis of the rotating wheel 322; the traction end 22 is provided with a hook 324; the hook 324 has a hanging rod 3241 extending along the second direction L2; the hanging rod 324... 1 is respectively set perpendicular to the axis of the first direction L1 and the axis of the rotating wheel 322; during the unidirectional rotation of the rotating wheel 322, when the rotating wheel 322 rotates from the second angle to the avoidance angle range between the first angle and the second angle, the lever 323 avoids the movement path of the hanging rod 3241; during the unidirectional rotation of the rotating wheel 322, when the impact rod 2 is in the equilibrium position and the rotating wheel 322 rotates to the first angle, the lever 323 is screwed into the hook 324 and contacts the hanging rod 3241; during the process of the rotating wheel 322 continuing to rotate from the first angle to the second angle, the hanging rod 3241 is located on the movement path of the lever 323, and the lever 323 pushes the impact rod 2 to the retracted position through the hanging rod 3241. Thus, the driver 321 drives the rotating wheel 322 to rotate; a lever 323 is provided on the rotating wheel 322, and when the rotating wheel 322 rotates, it drives the lever 323 to rotate around the axis of the rotating wheel 322; when the rotating wheel 322 rotates from the second angle to the avoidance angle range between the first angle and the second angle, the lever 323 avoids the hook 324, so that the lever 323 can disengage from the hook 324; when the rotating wheel 322 rotates to the first angle, the lever 323 contacts the hanging rod 3241 of the hook 324; when the rotating wheel 322 rotates from the first angle to the second angle, the hanging rod 3241 is located on the moving path of the lever 323, assuming an impact rod. 2. The direction of movement from the equilibrium position to the retracted position is the direction of power storage movement. The angle between the direction of movement of lever 323 and the direction of power storage movement is an acute angle. Lever 323 pushes impact rod 2 toward the retracted position through hook 324. When the wheel 322 rotates to the second angle and passes the second angle, lever 323 avoids the movement path of hook 324, so that hook 324 and lever 323 can separate from each other. Since the first direction L1, the axis of wheel 322 and hook 3241 are perpendicular to each other, lever 323 and hook 3241 are easily separated during the process of contacting hook 3241 and pushing hook 324 to move.
