    摘要： The methods and devices of the invention include an encoder, an endoscopic robotic instrument, and an encoder/robotic instrument interface. A preferred embodiment of the encoder has a chest/shoulder plate provided with telescoping tubes and joints. Each joint is provided with a direct drive potentiometer to monitor movement and provide a corresponding signal. The chest plate is preferably adaptable to a large range of human chest sizes and the telescopic segments are strapped to the arms of the practitioner at the elbows. A pistol grip is provided at the wrist end of the telescopic segments. According to the presently preferred embodiment, the encoder encodes flexion and rotation at the shoulder, elbow and wrist of each arm in addition to gripping at each hand. The encoding device is coupled to a circuit which operates a servo system. The servo system includes a series of servo motors. A series of pulleys corresponding to the number of servo motors are arranged in a housing. The robotic instrument preferably comprises two arms mounted at the distal end of a multi-lumen tube. Each arm has rotational and flexional joints corresponding to the shoulder, elbow, and wrist of the practitioner. Tendons are coupled to the pulleys of the servo motors and are fed through the multi-lumen tube to the joints of the two arms.

    摘要： Radioactive therapeutic seeds include a carrier structure bearing a radioactive isotope and a radiopaque marker. According to embodiments of the invention, the seeds include a central plug provided with an axial marker and a relatively transverse bore extending through the marker. A second marker may be positioned in the bore, thereby radiographically distinguishing a seed provided with the second marker relative to a seed not provided with the second marker. According to another embodiment of the invention, the isotope is deposited on the outer surface of a hollow radiolucent tube. A biologically-compatible, radiolucent, surface-sealing layer seals the external surface of the tube. A radiopaque marker wire of selected length is positioned in the hollow of the tube. Seeds may be radiographically distinguished from one another by providing seeds with marker wires of different lengths. Each embodiment permits at least two groups of seeds to be radiographically distinguished from one another by the use of differing marker configurations. Each embodiment is further capable of being selectively marked by the physician prior to implantation of the seeds, or by the manufacturer for delivery to the physician in radiographically distinguishable sets. As a result, seeds having different levels of radiation emission can be distinguished in vivo and their effect monitored by the physician.

    摘要： Methods of endoscopic surgery are disclosed. The methods utilize a suction/irrigation endoscopic instrument and a second endoscopic instrument. The suction/irrigation endoscopic instrument has a cannula, a fluid chamber in communication with the cannula, and an automatic valve at the proximal end of the fluid chamber. The second endoscopic instrument has end effectors and actuating means, and the end effectors of the second endoscopic instrument is inserted through the automatic valve, through the fluid chamber, and through the cannula. The methods involve inserting the suction/irrigation instrument through a trocar tube, and then inserting the second endoscopic instrument therethrough. The automatic valve insures that there is no leakage when the second instrument is inserted. The second endoscopic instrument may rotated inside, or may be partially withdrawn into the suction/irrigation instrument. Upon removing the second endoscopic instrument, the valve of the suction/irrigation instrument automatically closes so that there is no leakage. If desired, the suction/irrigation instrument may be provided with a cautery current at the cannula, and the second endoscopic instrument may be provided with a bump which contacts the cannula as a cautery pick-up.

    摘要： Radioactive therapeutic seeds include a substantially radiotransparent cylindrical capsule containing a radioactive isotope and, in particular embodiments, a radiopaque or MRI-visible marker. Each of the embodiments is designed to provide a substantially isotropic distribution of radiation. In one embodiment, the isotope is deposited on the outer surface of a hollow radiolucent tube and a collar is provided about a central portion of the tube. The capsule comprises two tubular halves positioned over the tube with the open ends of the halves forming an interference fit with the collar and welded thereabout. In another embodiment, the isotope bearing structure is a plurality of radiolucent spheres provided with a thin coating of silver to facilitate the adhesion of the isotope thereto. The spheres are provided in two capsule halves which are welded closed about a plug have an axial radiopaque marker therein. In yet another embodiment, the isotope bearing structure is a pair of silver tubes having surfaces on which the isotope is provided. One tube is positioned in each half of the capsule, and the halves are then welded about a plug provided with a marker. In each embodiment, the closed ends of the capsule are provided with tissue engaging members or connectors which can be coupled to discrete spacing links.
