摘要:
An inner member rotatable in an angled outer tubular member of a rotary surgical cutting instrument includes first and second tubular members. The first tubular member includes rigid proximal and distal portions comprised of a first material and a flexible intermediate portion comprised of a second material. The proximal portion includes a hub. The distal portion terminates at a distal end configured to couple with a cutting tip. The intermediate portion extends between and is fixedly coupled to the proximal and distal portions.

An electrosurgical instrument. The electrosurgical instrument includes a first arm, a second arm and a coupling system. The first arm includes a first jaw. The second arm is pivotably connected to the first arm and includes a second jaw, a cutting member movable within the first and second jaws, and a cutting member trigger. The coupling system includes a coupling member mechanically coupled to the cutting member trigger. The coupling member is movable between a first position and a second position. In the first position of the coupling member, the cutting member is mechanically uncoupled from the cutting member trigger. In the second position of the coupling member, the cutting member is mechanically coupled to the cutting member trigger.

An endoscopic endocap for excising a target portion of a native tissue from a remaining portion of the native tissue during a surgical procedure includes an annular main body. The main body has a proximal end and an oppositely disposed distal end. The distal end includes an extension that protrudes longitudinally beyond a remaining portion of the distal end. An outer surface of the distal end, and an inner surface of the main body, extend longitudinally between the proximal and distal ends. The inner surface defines at least one lumen with an opening terminating at the terminal portion of the distal end. At least one excisor is disposed on the extension with the excisor is laterally spaced from the outer surface of the annular main body. The excisor remains stationary with respect to the lumen during use of the excisor to excise the target portion of the native tissue.
摘要:
A tool for removing debris from sockets containing screws of electrical conductors of medical pacemakers, to allow engagement of screw heads for unthreading. The tool includes a body, with a screw driving blade projecting from one end and a cutting blade of diameter similar to that of the screw driving blade projecting from an opposed end. Optionally, the body encloses torque limiting components limiting torque applied to the screw driving blade. The screw driving blade may be polygonal. The cutting blade may be a fluted drill bit. Where the torque limiting components are not provided, the body may bear external splines, with the screw driving blade and cutting blade being monolithic with the body.

An anti-clogging device for a vacuum-assisted tissue removal system is provided. The device includes a tissue-separation chamber in a close proximity to (i) a cutting head operated by a physician and (ii) the physician for a filling and emptying by the physician during a tissue removal procedure, the cutting head and the tissue separation chamber in an operable communications with the suction assembly. The tissue separation chamber has an entry port in an operable communication with the cutting head for the entry of an excised tissue into the chamber, the excised tissue having a solid component and a liquid component; a baffle to separate the liquid component from the solid component; and, an exit port for the exit of liquid component out of the chamber. The tissue can include any tissue accessible through a small surgical opening, such as a nucleus pulposus tissue removed during a discectomy procedure.
