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.

An image pickup apparatus for endoscope includes: an image pickup member provided with a plurality of image pickup side faces; a first optical member provided with first side faces; a first bonding layer bonding together the image pickup member and the first optical member; a second optical member provided with second side faces; and a second bonding layer bonding together the second optical member and the first optical member, in which a plurality of first side faces include first near side faces closer to an optical axis than are the second side faces and the image pickup side faces, and the image pickup apparatus for endoscope further includes a sealing resin covering the first near side faces, at least part of the first bonding layer, and the second bonding layer.

Presented is a handheld dental bur that securely holds and offers secured tightening of a dental bur. The handheld dental bur includes a handle portion having a first end with a set of female threads and a second end to receive at least a tightening tool or a clamping tool. The handheld dental bur further includes a Micro-Chuck Assembly (MCA) that includes a collar with a hollow anterior, a collet with an elongated opening located in between multiple double-tapered prongs for receiving a shank portion of the dental bur, and a set of male threads. Further, the handheld dental bur includes a washer disposed of around an end of the collar separating the handle and the collar. The male threads of the collet engage with the female threads provided by the handle portion to detachably attach the MCA to the handle portion.

Disclosed is a surgical hand drill which drills a hole into which a fixture is inserted during an implant procedure, wherein at the end of the hand drill is a circular hollow plate attached thereto and at the other end is a handle. The circular hollow plate has a concave part and a convex part, and a circular drill bit is inserted into the hollow plate, the circular drill bit having a flat surface corresponding to the concave and convex parts of the hollow plate so that the convex part of the hollow plate having the concave and convex parts is inserted into the flat surface of the circular drill bit, thereby preventing the circular drill bit from separating from the hand drill even when rotated in forward or reverse directions.
