US 5,498,258 A · Laser resectoscope with laser induced mechanical cutting means

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.

Dependent claims

A laser resectoscope for coagulating, lasing, resecting and removing tissue from a patient, said device comprising:

a) an elongated cylinder, said cylinder having at the distal end a means for introduction into said patient;
b) rotatable means for directinq a beam of laser radiation within said cylinder from a source of laser radiation;
c) a laser beam contacting head at the distal end of said laser directing means and rotating therewith, said contact laser head having cutting blades for cutting away tissue;
d) motor means at the proximal end of said cylinder for rotating said laser directing means;
and
e) means within said cylinder for removing resected tissue, whereby said laser beam heats said laser beam contacting head and said cutting blades.
