The utility model discloses a photoacoustic imaging probe with a dustproof structure, which comprises a probe main body, a
signal acquisition optical window is arranged on the front side of the probe main body, and a dustproof ventilation
assembly is arranged on the front side of the probe main body. The dustproof sealing plate is clamped with the clamping groove through the clamping block to seal the
signal acquisition optical window, the internal ventilation and water blocking structure can block dust and
body fluid from invading and maintain air circulation so as to keep dry, the
laser energy transmission efficiency is guaranteed, and the dustproof sealing plate can be quickly overturned and opened through the rotating shaft to be clamped into the groove to achieve fixation during use. The whole operation is convenient and fast, extra tools are not needed, high-frequency scenes are adapted, the manual cleaning frequency is reduced, in addition, the dustproof ventilation
assembly is integrally integrated on the front side of the probe body, the structure is compact, no extra space is occupied, sealing stability is ensured through the clamping
connection design, and the problem that a traditional split type sealing cover is prone to being lost or losing
efficacy is solved.
