ABSTRACT:
The present invention provides a device and method for coagulating, lasing, resecting and removing prostate and bladder tissue. The device is a laser resectoscope containing laser induced mechanical cutting. The tips of the cutting blades are coated with Teflon and Stainless Steel to prevent adherence of the lased or resected tissue. The contact laser head and cutting blades are heated by a laser beam. This allows the operator to lase and resect the targeted tissue without impairing the cellular integrity of the tissue. Consequently, the retrieved tissue is preserved for histological analysis.
A method is also provided to coagulate, lase, resect and remove tissue from the prostate and bladder areas using the above mentioned laser resectoscope with laser induced heating.
