A surgical guide comprising a body including an inner surface that defines a cavity configured for disposal of a surgical instrument. The body further defining an opening communicating with the cavity. A connector disposable with the opening and engageable with a surgical robot. A release is engageable with the connector. Systems, spinal constructs, implants and surgical instruments are disclosed.

In some embodiments, the current invention relates to a method and/or system for using a standard dental handpiece for endodontic cleaning. For example, a dental adapter is disclosed having a fitting for a standard dental handpiece, a torque limiter and/or a mount for an endodontic file. For example, the adapter may be single use and/or multi use. In some embodiments, the mount includes the torque limiter. For example, an endodontic file may be connected to the mount with a friction fitting that allows rotation of the file with respect to the mount at high torque. Optionally the mount is positioned eccentrically with respect to the fitting.

A dental handpiece is a dental handpiece configured to detachably hold a cutting tool. The dental handpiece includes: a holding portion provided with an insertion port into which the cutting tool is insertable, the holding portion being configured to hold the cutting tool inserted in the insertion port; and a main body portion configured to accommodate the holding portion, the main body portion being provided with a water introduction hole and a plurality of chip air holes. The plurality of chip air holes are disposed to sandwich the water introduction hole in a second direction, the second direction intersecting a first direction in which the insertion port and the water introduction hole are arranged.

A dental handpiece includes a main body portion, a holding portion, and a releasing mechanism. The releasing mechanism includes a cap, a cap ring, and a push cap. The cap includes an outer annular portion and an inner annular portion provided with at least one window portion. The push cap is configured to be movable to a releasing position between the outer annular portion and the inner annular portion in a direction in which the push cap is put on the cap ring, the releasing position being a position at which the holding portion is released. The cap ring includes at least one claw portion anchored to the at least one window portion from the inner side. The at least one claw portion is disposed on the inner side with respect to the inner annular portion.

A shaft for a dental screwdriver configured to be inserted into a bore cavity of a dental prosthetic. The shaft has a drive tip for driving a dental screw used to fix the dental prosthetic to the dental implant when the shaft is inserted into the bore cavity of the dental prosthetic. The drive tip is made of a shape memory smart alloy. The shaft also has an axial shaft portion made of a shape memory smart alloy with different material characteristics than the shape memory smart alloy of the drive tip. The axial shaft portion is configured to elastically bend from an original shape to a bent shape along the axial shaft portion without imparting a bending action and torqueing forces along the drive tip when the dental screwdriver is inserted into the bore cavity of the dental prosthetic.

A handle system for supporting a tool defining a tool axis during the performance of dental procedures comprises a handle defining a handle axis, a rotation sleeve, a head assembly and a gear set comprising first and second gear portions. The rotation sleeve supports the first gear portion. The head assembly supports the second gear portion. The handle supports the rotation sleeve for rotation relative to the handle. The handle supports the head assembly such that the first gear portion engages the second gear portion. With the head assembly supported by the handle, the head assembly engages the tool to support the tool such that the tool axis extends at a first angle relative to the handle axis and rotation of the rotation sleeve relative to the handle causes axial rotation of the tool about the tool axis.

A medical dental grinding apparatus comprises an apparatus body, wherein an air pipeline, a clamping mechanism, and a grinding mechanism are provided in the apparatus body; the air pipeline includes an air inlet pipeline, an air outlet pipeline, and a U-shaped connection pipeline; a silencer is connected to an upper port of the air outlet pipeline; a plane where the air pipeline is located is perpendicular to a plane where the clamping mechanism is located, and the grinding mechanism is provided below the air pipeline. According to the present invention, the grinding mechanism is driven by high-pressure air in the air pipeline to operate, so that a hidden danger of electric leakage caused by using an electric apparatus in a fragile oral environment is avoided; and a steel wire is fixed by means of the clamping mechanism, so that the grinding safety is ensured.

A connecting chuck of a material cylinder for a mixer and a mixer are disclosed according to the present application. The chuck includes a chuck body, and a first axial position-limiting connector and a second axial position-limiting connector are provided on the chuck body. After the chuck body rotates around the outlet pipe of the material cylinder by a preset angle, the first axial position-limiting connector can cooperate with a first axial position-limiting cooperating member on the material cylinder, and the second axial position-limiting connector can cooperate with a second axial position-limiting cooperating member on the mixer, so that an inlet pipe of the mixer is compressed with the outlet pipe of the material cylinder for cooperation. Through the above structure, after use, the chuck body reversely rotates to an initial position and the mixer is replaced, and the chuck body is reusable without replacement.

A wearable controller for a dental handpiece system and a dental handpiece system are disclosed. The wearable controller includes a wearable body. The wearable body includes an input and a display, the input and the display for displaying a graphical user interface (GUI) to an operator providing a plurality of operating selections. A battery is electrically connected to the input and the display for powering the input and the display. A reservoir is secured to the wearable body. An output is electrically connected to the input and the display for receiving an indication of an alert.
