An instrument for obtaining tissue samples from a site deep within the body. The instrument has an elongated proximal portion that is constructed to follow a long, torturous path to the site and has a distal end constructed to sever and remove a tissue sample from the body, including tissue specimens, polyps or the like. The instrument is constructed to take multiple biopsy samples without being withdrawn from the body. The instrument includes a tissue sample retractor. The retractor is axially movable between an extended tissue-engaging position and a retracted position. There is an open passage into which the retractor moves when moving from the extended to the retracted position. The retractor has a distal end portion constructed to engage tissue and apply axial transporting force thereto while moving from the extended to the retracted position. The retractor is constructed to be advanced and retracted repeatedly to accumulate a series of samples in the instrument.

Moveable sample tube multiple biopsy sampling device

This invention relates to a device for pressure fusing dry, powdered toner particles to a copy sheet in an electrostatic copier. The pressure fusing device comprises a rigid member against which fusing pressure can be applied and a plurality of independent, freely movable rollers for applying fusing pressure to a copy sheet.

This invention relates to a compact, lightweight pressure fusing device for permanently fixing electrostatic toner onto a copy sheet. The pressure fusing device of this invention includes a first cylindrical pressure fusing roll and a second cylindrical pressure fusing roll. The pressure fusing rolls are positioned to form a nip therebetween. The pressure fusing rolls are each relatively rotatable about their respective longitudinal axis. Either or both of the rolls may be driven. Each of the pressure fusing rolls is rotatably fixed within a substantially rigid bearing housing and is rotatable on a bearing within the bearing housing. Both the bearing and bearing housing extend substantially the entire longitudinal length of the pressure fusing roll so that pressure applied to the bearing housing is transmitted uniformly along the roll axis of each pressure fusing roll and the roll is constrained against longitudinal deflection.
