A surgical instrument has a hollow tubular member, and a pressurization unit that has an outer valve portion, a pressurization device having a movable part configured to generate pressurized fluid when the movable part is moved, and an inner valve portion. The inner valve portion includes a first flow passage that is configured to fluidically connect a first port and a second port of the outer valve portion to each other when the inner valve portion is in a first position, and a second flow passage that is configured between the inner valve portion and the outer valve portion to fluidically connect the first port and a third port when the inner valve portion is in a second position. A sealing system fluidically isolates the second port and the third port from each other at any position of the inner valve portion. Pressurized fluid from the pressurization device causes the inner valve portion to move from the first position to the second position, thereby providing positive pressure to the hollow tubular member.

Surgical instrument

An article including: a battery support containing battery lead wires attached to terminals; an opposing battery support attached to the battery support to create a battery closure; one or more batteries having battery contacts in the opposing battery support; and one or more activation tabs; wherein the terminals are attached to spring-loaded members; wherein the one or more activation tabs are spaced between the terminals and the battery contacts; wherein the spring-loaded members provide a biasing force that biases the terminals against the activation tabs keeping the one or more activation tabs in place in either a first position or a second position of the opposing battery support; wherein the opposing battery support is securely connected to the battery support in both the first position and the second position; and wherein the biasing force is greater in the second position than in the first position.

Destructive battery closure

An article comprising: (i) a handheld device including (a) a housing, (b) a powered element within the housing; (ii) a battery pack, wherein the handheld device is connected by an external cable to a functional system, wherein the battery pack is attached to the external cable, and wherein the battery pack supplies power to the powered element.

Battery pack attached to a cable

An article comprising: (i) a handheld device including (a) a housing, (b) a powered element within the housing: (ii) a battery pack, wherein the handheld device is connected by an external cable to a functional system, wherein the battery pack is attached to the external cable, and wherein the battery pack supplies power to the powered element.

An article comprising: (a) a battery support containing battery lead wires, (b) an opposing battery support attached to the battery support to create a battery closure, and (c) one or more batteries; wherein the batteries are secured in the battery closure, wherein the batteries are secured to the opposing battery support, the batteries supply energy to a device, and removing the opposing battery support from the battery closure disables transmission of electricity from the batteries via the battery lead wires to the device.

A mechanical cutting device that makes use of mechanical (rotary) motion and suction to engage tissue also applies a cutting energy sufficient to vaporize the tissue. The rotation and suction are used to engage the tissue (sucking tissue into cutting windows when the cutting windows of inner and outer blades are aligned), and then the cutting member(s) function as an electrode(s) by having an electrical cutting signal applied thereto so that the cutting member(s) electrically cut the tissue as the cutting members relatively rotate. The electrical cutting signal is only applied as the windows become aligned up until the cutting of the tissue is completed. The cutting signal preferably is stopped after the cutting windows become misaligned. While the cutting windows are misaligned, a coagulation signal can be supplied to the cutting member so that the device functions as an electrocautery device.

A powered surgical apparatus can be used with a source of irrigation fluid and a source of suction. The powered surgical apparatus can include a cutting blade assembly and a handle. The handle can include an upper portion defining a distal section connectable to the cutting blade assembly and a lower portion extending downwardly from the upper portion. The handle can be connectable to the source of irrigation fluid and the source of suction. The system can also include a manually actuable input device that provides at least one signal relevant to at least one operation of the system, and a controller that receives the at least one input signal and provides an output signal to perform the at least one operation of the system.

A surgical instrument comprises a hollow tube () having a cutting window () at the distal end portion. An inner tube () is disposed within the tube () and is mounted for rotation about its longitudinal axis. A cutting tool () is located at the distal end of the tube (), and is positioned adjacent to the cutting window (). An outer tube () is provided over the tube (). A motor () is provided for rotating the inner tube (), and saline is fed to the cutting window () via a passageway () between the tubes () and (). The inner tube () has a central lumen () through which tissue cut by the cutting tool () is removed under the action of a source of suction (). The outer surface of the tubeis covered with an electrically insulating layer () and coagulating RF signals are supplied between the tube () and the outer tube () so as to coagulate tissue at the cutting window (). Additional apertures () in the outer tube () and the insulating layer () are aligned such that a portion of the hollow tube () is exposed other than in the area of the cutting window ().
