Laboratory use of a microsurgical instrument, microsurgical instrument and force and torque transmission tube

摘要

The present invention discloses a surgical insert (10) for a microsurgical instrument having a proximal coupling portion (102) which is coupleable to a handle. A hollow shaft (1) extends from the coupling section (102) to a distal tool end (101), on which a jaw-shaped working device (2) rotatably mounted about the longitudinal axis of the shaft (1) is arranged with branches (21, 22) pivotable relative to one another is. Inside the shaft (1), a force and torque transmission tube (3) extends from the coupling portion (102) to the distal tool end (101) operatively connected to the working device (2). The force and torque transmission tube (3) is stiffened in at least one section lying between the coupling section (102) and the distal tool end (101) with at least one tension element (31) extending in the longitudinal direction of the force and torque transmission tube (3). In addition, a microsurgical instrument and the force and torque transmission tube (3) itself are disclosed.
