Abstract

The present invention relates to a handle (4),a head piece (6) and a wrench, such as a torque wrench, in particular for use in surgery and prosthetics, such as surgery and prosthetics within the dental field. A handle (4) for a wrench is provided, wherein the handle comprises an elongated body element (8) extending along a first axis, and a torque arm (10) for indicating the torque applied to thetorque arm (10), the torque arm having a proximal end attached to the body element (8). Furthermore, the handle (4) comprises a first locking element (22), the first locking element being adapted to removably engage with a locking element (22) of a head piece, and the handle (4) further comprises a ratchet element (34) that is adapted to engage with a tool piece in a ratchet gear.

Description

technical field [0001] The invention relates to a handle, a head piece and a wrench, such as a torque wrench, in particular for use in surgery and prosthetics, for example in the field of dentistry. Background technique [0002] Because of the high number of hygienic requirements in operating theaters, tools and devices used in surgery and surgical procedures must be easy to clean. Known torque wrenches comprise a large number of small parts which must be removed before cleaning and reinstalled after cleaning, thus making cleaning a tedious and difficult task. Contents of the invention [0003] It is therefore an object of the present invention to provide a torque wrench which is easy to handle during removal and installation. [0004] Another object is to provide a torque wrench with a detent function such that when the torque wrench is rotated in one direction, the torque wrench engages a tool coupled to the torque wrench and when rotated in the opposite direction When...
