SURGICAL, TORQUE-TRANSMITTING INSTRUMENT INCLUDING ASSOCIATED TOOL Russian patent published in 2018 - IPC A61B17/16 

FIELD: medicine.

SUBSTANCE: invention relates to a medical equipment, namely to a surgical torque-transmitting device. Device comprises a handle. Handle shaft is flange-mounted or can be flange-mounted to the handle. In the handle there is a tool receiving element, for selectively receiving a rotatably mounted surgical tool or a surgical tool which can be rotatably mounted therein for axially securing the tool in the tool receiving element and for transferring torque to the tool. Tool receiving element comprises one at least partially sleeve-shaped drive shaft. Drive shaft comprises a proximal insertion area for a torsion shaft and distal torque transmission areas and axial locking areas for the tool. Torque transmission area is distal to the axial locking area. Tool receiving element comprises a closing sleeve surrounding the drive shaft rotationally and displacably. Closuring sleeve comprises a distal blocking section interacting with the axial locking region of the drive shaft for axially locking and releasing the tool, and a proximal stopping section. Proximal stopping section interacts on the insertion region of the drive shaft for locking the tool receiving element on the torsion shaft for transmitting torque and axial forces, and for releasing the tool receiving element with respect to the torsion shaft.

EFFECT: best functionality is achieved by creating a tool for a torque-transmitting device, and a system comprising a handle of a surgical device and at least one tool, each of which allows achieving better functionality, is provided.
