Abstract: A force-limiting and damping device has a body, a tapping element, an elastic element, and a reinforcing element. The body has a connecting segment with a mounting hole. The tapping element is movably connected to the body and has a mounting segment, a tapping segment, a fixing segment, and a protrusion segment. The protrusion segment is formed on a connecting portion between the mounting segment and the tapping segment. The reinforcing element is mounted on the tapping element between the elastic element and the tapping segment of the tapping element and abuts against the protrusion segment. The force-limiting and damping device can improve structural strength, can prolong service life, and can avoid deflection during a tapping process.

Abstract: A hand tool with a buffering effect has a body, a working element, and at least one shock-absorbing element. The body has a holding end and a connecting end respectively disposed on two ends of the body. The working element is connected to the connecting end of the body. The least one shock-absorbing element is disposed on the body between the holding end and the connecting end and has a length being larger than a half of a length of the body and being less than or equal to the length of the body. A user holds the body and uses the working element, and a shock-absorbing and buffering effect is provided by the at least one shock-absorbing element.

Abstract: A dental tool has a body and a working element. The body has a connecting portion and a measuring portion. The connecting portion is disposed on an end of the body. The measuring portion is formed on an external surface of the body opposite to the connecting portion. The working element is connected to the body and has a connecting end and a working end. The connecting end of the working element is connected to the connecting portion of the body. The working end of the working element is connected to the connecting end of the working element and extends out of the connecting portion. The working element of the dental tool provides a detection effect, and the measuring portion of the body provides a measurement effect.

Abstract: A laser device for dentistry has a body, a light source group, and a light guiding pipe. The body has an outer casing, an operating module, and a controlling module. The light source group is disposed in the body and has multiple light-emitting elements, a reflector, a collimating mirror, and a focusing mirror. Each light-emitting element is a laser diode, is disposed at a connecting portion of the body and is electrically connected to the controlling module. The reflector is mounted around the light-emitting elements. The collimating mirror is disposed on a side of the reflector away from the light-emitting elements. The focusing mirror is disposed on a side of the collimating mirror away from the reflector. The light guiding pipe is detachably connected to the connecting portion of the body and is located on a front side of the light source group.

Abstract: A removing device for dentistry has a connecting pipe, a controller, and a sucking tube. The controller is connected to the connecting pipe and has two connecting portions and an operating portion between the two connecting portions. The two connecting portions connect in fluid communication with each other via the operating portion. One of the connecting portions is connected to the connecting pipe. The operating portion has at least one relief hole disposed on an external surface thereof and in fluid communication with the connecting portions and a flow regulator. The sucking tube is connected to the other connecting portion opposite to the connecting pipe to connect in fluid communication with the connecting pipe via the controller. By pressing the operating portion to shield the relief hole or adjust the flow regulator to control the suction force, the removing device for dentistry can be used conveniently and removed quickly.

Abstract: A bone graft carrier has a body. The body has a containing portion, a conveying portion, and an opening. The containing portion is formed at one of two ends of the body and has a chamber. The conveying portion is formed at the other one of the two ends of the body, is tapered, is connected to the containing portion, and has a delivery channel communicating with the chamber of the containing portion. The opening is formed through a top surface of the body and directly communicates with the chamber of the containing portion and the delivery channel of the conveying portion.

Abstract: A force-limiting and damping device has a body, a tapping element, a shock-absorbing element, and a limiting module. The body has a connecting segment and a holding segment. The tapping element is connected to the body to move relative to the connecting segment and has a mounting segment, a tapping segment, and a fixing segment. The mounting segment is movably connected to the connecting segment. The tapping segment is disposed on an end of the mounting segment below the connecting segment. The fixing segment is connected to the mounting segment and abuts the connecting segment. The shock-absorbing element is mounted on the mounting segment and abuts the connecting segment and the tapping segment. The limiting module is mounted between the body and the tapping element and has a force-limiting element mounted between the mounting segment and the connecting segment to provide a force-limiting reminder effect and a damping effect.

Abstract: A force-limiting and damping device has a body, a tapping element, and an elastic element. The body has a connecting segment and a holding segment. The connecting segment is formed on an end of the body and has a mounting hole. The holding segment is formed on the body opposite the connecting segment. The tapping element is connected to the body to move relative to the connecting segment. The elastic element is mounted between the tapping element and the connecting segment to abut against the tapping element and to enable the tapping element to move relative to the connecting segment. The structural relationship between the connecting segment, the tapping element, and the elastic element may provide a delayed rebound and damping effect to the reaction force, and the applied force is continuously transferred to a tapping object. This may reduce noise and the loss of energy.
