A disposable tissue removal device comprises a 'tube within a tube' cutting element mounted to a handpiece. The inner cannula of the cutting element defines an inner lumen and terminates in an inwardly beveled, razor-sharp cutting edge. The inner cannula is driven by both a rotary motor and a reciprocating motor. At the end of its stroke, the inner cannula makes contact with the cutting board to completely sever the tissue. An aspiration vacuum is applied to the inner lumen to aspirate excised tissue through the inner cannula and into a collection trap that is removably mounted to the handpiece. The rotary and reciprocating motors are hydraulically powered through a foot pedal operated hydraulic circuit. The entire biopsy device is configured to be disposable. In one embodiment, the cutting element includes a cannula hub that can be connected to a fluid source, such as a valve-controlled saline bag.

Biopsy apparatus

A disposable tissue removal device comprising a cutting element mounted to a handpiece. The cutting element includes an outer cannula defining a tissue-receiving opening and an inner cannula concentrically disposed within the outer cannula. The outer cannula has a trocar tip at its distal end and a cutting board snugly disposed within the outer cannula. The inner cannula defines an inner lumen that extends the length of the inner cannula and terminates in an inwardly beveled, razor-sharp cutting edge. The inner cannula is driven by both a rotary motor and a reciprocating motor. At the end of its stroke, the inner cannula makes contact with the cutting board to completely sever the tissue. An aspiration vacuum is applied to the inner lumen to aspirate excised tissue through the inner cannula and into a collection trap that is removably mounted to the handpiece. The rotary and reciprocating motors are hydraulically powered through a hydraulic circuit. The hydraulic circuit includes a foot pedal that initiates aspiration vacuum, rotary motion and reciprocation of the inner cannula. The hydraulic circuit is configured so that the inner cannula closes the tissue-receiving opening before the foot pedal is depressed and automatically after the foot pedal is released.

A rotating surgical system is provided that includes a base, a first member rotably engaged with the base, and a second member fixed with said first member such that said first member and said second member rotate together.

Rotating surgical cutter

A disposable tissue removal device comprises a 'tube within a tube' cutting element mounted to a handpiece. The inner cannula of the cuffing element defines an inner lumen and terminates in an inwardly beveled, razor-sharp cutting edge. The inner cannula is driven by both a rotary motor and a reciprocating motor. At the end of its stroke, the inner cannula makes contact with the cutting board to completely sever the tissue. An aspiration vacuum is applied to the inner lumen to aspirate excised tissue through the inner cannula and into a collection trap that is removably mounted to the handpiece. The rotary and reciprocating motors are hydraulically powered through a foot pedal operated hydraulic circuit. The entire biopsy device is configured to be disposable. In one embodiment, the cutting element includes a cannula hub that can be connected to a fluid source, such as a valve-controlled saline bag.

Selectively detachable outer cannula hub

A tissue cutting device is provided that includes an outer cannula defining an outer lumen and a tissue-receiving opening adjacent a distal end of the outer cannula in communication with the outer lumen. An inner cannula is slidably disposed within the outer lumen and defines an inner lumen from an open distal end to an open opposite proximal end. The inner cannula includes a cutting edge at the open distal end operable to sever tissue projecting through the tissue receiving opening. A first hydraulic rotary motor is operably coupled to the inner cannula to rotate the inner cannula within the outer cannula. A second hydraulic reciprocating motor is operably coupled to the inner cannula to translate the inner cannula within the outer cannula while the inner cannula rotates. A hydraulic system provides the first and second hydraulic motors in communication with a source of pressurized fluid.

Integrally-molded with a plastic TV cabinet is a collapsible holding member. When a PCB is mounted on the TV cabinet at an assembly station, the collapsible holding member squeezes through an aperture in the PCB to temporarily secure the PCB to the TV cabinet. The partially-installed product is then moved to a screw driving station, where the PCB is permanently screwed to the TV cabinet.
