A focused ultrasound probe comprises a shell, a flexible film, a control device, and an emitter. In which, the top of the shell is provided with an opening, and the opening may communicate the interior of the shell with the exterior. The flexible film is combined with the shell and seals the opening. The control device comprises a guiding mechanism and a moving member. The guiding mechanism is disposed inside the shell and comprises a first guiding rail and a second guiding rail, wherein the first guiding rail moves along the second guiding rail, and the moving member moves along the first guiding rail. The emitter is located inside the shell and combined with the moving member for generating ultrasonic wave. Thus, when the area of the subcutaneous target tissue is larger, the emitter may move horizontally inside the shell, and the ultrasonic wave emitted by the emitter may be still focused on the same horizontal position of the subcutaneous target tissue to achieve better treatment effect for the subcutaneous target tissue.一種聚焦型超音波探頭包含有殼體、可撓性膜、操控裝置以及發射器，其中殼體頂部具有一開口，且開口連通殼體內部與外部；而可撓性膜結合於殼體且封閉開口；操控裝置包括導移機構以及移動件，且導移機構設置於殼體內部且包括第一導軌與第二導軌，且第一導軌係沿著第二導軌移動，而移動件沿著第一導軌移動；發射器位於殼體內部且結合於移動件，並用以產生超音波，藉此，當皮下目標組織面積較大時，發射器可以於殼體內部呈水平移動，且發射器所發出的超音波仍可以聚焦於皮下目標組織的同一水平位置，達到對皮下目標組織較佳的處理效果。
