Power-assisted arthroscopic surgical device with suction tube

摘要

The handpiece includes a housing, a drive device within the housing for driving an inner member of a tool. A releasable collet device is used for receiving the surgical tool and holding it longitudinally fixed relative to the drive device. The collet device is adapted to receive the outer member of the tool in a set angular orientation relative to the axis of the housing. The handpiece also incorporates a device for enabling rotation of the collet device for varying the set angular orientation. The device includes a detent device to retain the collet in a selected position. The detent device is manually rotatable without being first manually urged longitudinally. The detent device includes a first locking plate contg a first locking surface facing in a distal direction. A second locking plate comprises a second locking surface facing in a proximal direction.
