Patent ID: 8906029

Claim:
A device for dispensing a material with thermoplastic properties in a flowable state at an operation site in a human or animal patient, the device comprising: a rotation drive, a dispenser element comprising a shaft portion with a longitudinal axis extending from a proximal end of the shaft portion to a distal end portion which is arranged at a distal end of the shaft portion and comprises a proximal or distal face, and a consumable element with a longitudinal axis extending from a proximal end to a distal end, at least a portion of the consumable element consisting of the material with thermoplastic properties, wherein either the consumable element or the shaft portion is adapted to the rotation drive to be coupled thereto and the consumable element or the shaft portion is designed to be capable of transmitting the torque of the rotation drive to its distal end, and the other one of the consumable or dispenser element is adapted to be held so as to not rotate, wherein the consumable element and the dispenser element are arranged or arrangeable with their longitudinal axes parallel to each other, and with a distal or proximal face of the consumable element in contact with the proximal or distal face of the end portion and the two faces are capable of being pressed against each other with an advancement force putting a compressive load on the consumable element along its longitudinal axis and being applied to the proximal end of the consumable element and a counter force to the distal end of the consumable element, whereby a relative rotational movement and therewith frictional energy between the consumable element and the dispenser is creatable, which friction energy causes the material with thermoplastic properties to be transformed from the solid into the flowable state.
