Abstract
(EN)
A computer controlled rectal biopsy probe (10) is employed to receive an ultrasonic signal from an ultrasonic transmitter (39). Biopsy probe (10) is provided with a gimbaled head portion (12), and an elongated shaft portion (14). The aft end of probe (10) is gear connected to a stepper motor (16) via gears (17, 18) to effect controlled rotation of the probe. The mapping probe signal is employed by the biopsy probe to position a biopsy needle (34) within the rectal wall (29) in alignment with a suspect prostate tumor (35) detected by the mapping probe (40). The biopsy needle is computer controlled to penetrate the rectal wall, extend into the center of suspect tumor, and cut a tissue sample therefrom.

On utilise une sonde (10) de biopsie rectale commandée par ordinateur qui reçoit un signal ultrasonique provenant d'un émetteur ultrasonique (39). Cette sonde de biopsie (10) est pourvue d'une partie de tête (12) suspendue à la Cardan, et d'une partie de tige allongée (14). La partie arrière de la sonde (10) est reliée par les engrenages (17, 18) à un moteur pas à pas (16) afin d'effectuer la rotation commandée de la sonde. Un signal provenant d'une sonde de mappage est utilisé par la sonde de biopsie pour positionner une aiguille à biopsie (34) à travers la paroi rectale (29) et l'aligner avec une tumeur suspecte (35) de la prostate détectée par la sonde de mappage (40). L'aiguille à biopsie, qui est commandée par ordinateur, transperce la paroi rectale jusqu'à atteindre le centre de la tumeur suspecte et y découper un échantillon de tissu.
