Endoscopic biopsy forceps handle with removable sample removal pick

摘要

An endoscopic biopsy forceps instrument includes an actuation handle having a stationary member coupled to a movable member, a tubular member coupled at its proximal end to the stationary member, a control wire extending through the tubular member and coupled at its proximal end to the movable member, and a biopsy forceps jaw assembly having jaw cups. The jaw assembly is coupled to the distal ends of the tubular member and control wire, such that movement of the movable member relative to the stationary member imparts relative movement of the control wire relative to the tubular member and opens and closes the jaws. The distal end of the stationary member includes a groove for holding a sample removal pick. A sample removal pick shaped to be slidably engaged in the holder is received within the holder. The pick may include catches and ridges for engagement by a human finger, such that the catches and ridges may be engaged by the practitioner to slide the pick out of the holder. The pick can then be used to remove tissue samples lodged within the jaw cups of the jaw assembly.
