A kind of guiding device with the indent correction of what thoracic cavity, the ultrasound scanner head comprising a guide instrument and an installation what guide instrument. The guide instrument has the guiding sheet body of a lever and the fixed what lever of an installation and the long sheet toward the curved extension of outer arc, and the guiding sheet body terminal part is equipped with a perforation. The ultrasound scanner head is to install fixed what guiding sheet body terminal part, and can emit towards the guiding sheet body terminal part extending direction and receive ultrasonic signal. The structure design that a ultrasound scanner head is fixed through the installation of the what guide instrument front end, so that the probability that the guide instrument injures blood vessel or heart can be greatly reduced when guiding device what thoracic cavity indent corrective procedure, so can relative reduction operation risk.一種用於胸腔內凹矯正之導引裝置，包含一導引器械與一安裝於導引器械之超音波探頭。該導引器械具有一握柄，及一安裝固定於該握柄並往外弧彎延伸之長片狀的導引片體，且該導引片體末端部穿設有一穿孔。該超音波探頭是安裝固定於該導引片體末端部，並可朝該導引片體末端部延伸方向發射與接收超音波訊號。透過於該導引器械前端安裝固定一超音波探頭的結構設計，使得該導引裝置用於胸腔內凹矯正手術時，可大幅降低該導引器械傷及血管或心臟的機率，所以可相對降低手術風險。
