Methods for using same to detect and treat diseases such as cancer cells and body tissue. Medical materials, such as drug compounds usable with such instruments, are provided for detecting, marking and treating diseases such as cancer and preventing the spread of cancer. An instrument is provided which is capable of detecting a malady, such as a tumor, cancer,lesion, ulcer or other type of wound in a body duct of a living being which instrument may also be automatically operated to treat such a malady, such as by performing a surgical operation thereon.Field of SearchWith means for cutting, scarifying, or vibrating (e.g., ultrasonic, etc.) tissueMaterial impelled by spring Material conduit forced into body by spring Means for intermixing liquid with solid or different liquid Having plural material reservoirs With tool carried on endoscope or auxillary channel therefore Urogenital resectoscope Having tool moving or stopping means Having tool raising platform With camera or solid state imager Fluid channel (e.g., suction, irrigation, aspiration) | |
