Title:
IN-VITRO TUMOR LOCALIZATION APPARATUS BASED ON PHOTOACOUSTIC EFFECT
Document Type and Number:
WIPO Patent Application WO/2024/036791
Kind Code:
A1
Abstract:
An in-vitro tumor localization apparatus (200) based on the photoacoustic effect, which solves the problem that existing in-vitro tumor detection apparatuses cannot accurately localize tumors. The in-vitro tumor localization apparatus (200) comprises: a laser generator (1) which is in contact with the skin of a subject and is used for emitting a laser beam into the body of the subject; an ultrasonic probe (2) which is in contact with the skin and is used for detecting ultrasonic signals triggered by the laser beam; a signal processor (3) which is connected to the ultrasonic probe (2) and is used for processing ultrasonic signals; and an analyzer (4) which is connected to the signal processor (3) and is used for determining the presence of a tumor and the position thereof. The laser generator (1) comprises a handle (7) and a laser emission end (9) connected to the handle (7) by means of a ball-socket structure. A power supply (71) is arranged in the handle (7). A plurality of laser emission heads (91) are arranged on the laser emission end (9). The power supply (71) is electrically connected to a bus for the plurality of laser emission heads (91). The laser emission end (9) can ensure that the projection direction of the laser emission head (91) is always perpendicular to the skin, thereby avoiding inaccurate localization caused by tilts of the projection direction.
