Disclosed is a surgical probe (1), the surgical probe comprising a housing (10), said housing extending along a longitudinal extent from a proximal end to a distal end. A longitudinal cavity (14) is provided inside the housing and extends along a proximal-distal direction inside the housing, said cavity being open at a proximal front face and being closed at a distal front face. The housing comprises an aperture (11) provided in a distal region of the housing and through which the longitudinal cavity is in communication with the exterior of the housing at a circumferential position of the housing, such that the longitudinal cavity (14) is open at a circumferential position through the aperture (11). A blade (31) comprising a cutting edge (311) and an actuation transmission mechanism (32) is provided inside the housing and in the longitudinal cavity, wherein the blade (31) is disposed distal of the actuation transmission mechanism (32). The blade is displaceable in the cavity such as to move the blade between a retracted position in which the blade is entirely comprised inside the housing and an operative position in which the cutting edge of the blade is provided at least partially outside the housing. The actuation transmission mechanism is operatively connected to the blade such that an actuation of the actuation transmission mechanism causes said displacement of the blade, wherein the blade (31) and the actuation transmission mechanism (32) are integrally provided with each other to form an integral blade unit. The probe may in particular be suitable for hand surgery, for an instance for carpal tunnel, trigger finger or de Quervain's tenosynovitis release
