1. A surgical grip for receiving a handpiece shaft for conjoint rotation therewith and/or for receiving a medical tool in such a way as to transmit torque, comprising a carrier sleeve on which at least one coupling component provided for coupling the handpiece shaft is attached such that the at least one coupling component can be brought to a coupled position and to an uncoupled position in an operating state in which disassembly of the surgical grip is excluded, wherein the at least one coupling component can be brought into contact with an activation unit which is arranged between the carrier sleeve and an outer actuation sleeve by actuation of which the at least one coupling component can be coupled and/or uncoupled via the activation unit, wherein the surgical grip defines a longitudinal axis that extends through a center of the surgical grip, and wherein the surgical grip comprises a rotation securing unit present inside the actuation sleeve which acts on the activation unit in a spring-biased manner in the operating state such that the activation unit is held secure against rotation relative to the carrier sleeve, wherein the actuation sleeve comprises a one-piece tubular body having open ends and a completely closed one-piece wall of unitary construction that surrounds the carrier sleeve.
