The linear actuation of the cutters can allow for more robust cutting and increased cutting efficiency.

The side cutters include stationary cutter members and rotating cutter members that provide a precise shearing action.

Cutting members (22) extends from the hub (20).

The drill bit is less aggressive when the cutters are in the retracted position compared to when the cutters are in the extended position.

The penetrating endoscope may include end effectors such as cutters and forceps.

The invention is directed to tissue cutting members and biopsy devices with such tissue cutting member for separating a tissue specimen from a patient's body at a target site.

A cutting zone (38) is defined between the cutting units (12, 14) which is arranged to receive an item (40) to be cut.

The arrangement of said chopping members (7a, 7b, 7c, 7d, 7e) in this manner can be used advantageously to improve the removal of the chopped product towards the rear of said chopping device (4).

The cutters (2) are guided at a different level from the stops (3, 3') and borne by a suspended flexible strip (5) in the form of a polyurethane toothed belt.

The inner and outer cup members further each include a circumferential lip protruding outwardly with respect to the interior of the double-walled cup.

The machine (100) additionally includes a belt drive system to power the cutting units (108).

The external cutting members (4) are each rotatable about an axis of rotation (15) between different shaving positions.

The disposal apparatus has a plurality of cutters (34) disposed in a passageway for comminuting waste.

The lips of the inner and outer cup members are welded together so as to form a sealed insulating space thereby.

A plurality of under reamer arms are carried on the housing, the under reamer arms are formed as blocks including cutter-supporting portions in which poly-crystalline diamond compact cutters are mounted.
