Japanese Patent JPH05502605
Kind Code:
A
Abstract:
A laser soft tissue aspiration device comprises an aspiration cannula housing a laser energy transmitting means for conducting laser energy to the site within a patient's body for aspiration of soft tissue. The cannula is provided with an aspiration inlet port adjacent the cannula distal end. The proximal end of the cannula is provided with fluid flow connection to an aspiration source. A laser guide tube is additionally provided housing the laser energy transmitting means extending longitudinally within the cannula lumen from a laser energy source at the cannula proximal end and terminating at a point immediately prior to the aspiration inlet port. The tube also provides a conduit for transmitting cooling and cleaning fluid flow for the laser energy transmitting means. A surgical method of aspirating soft tissue from a patient in vivo using this device is also provided transmitting means. Separated soft tissue and fluid is aspirated through the aspiration inlet port and the cannula by means of an aspiration source at the proximal end of the cannula.
