ABSTRACT:
A medical locating apparatus including a main parallel link and subsidiary parallel links are formed by first second and third links, first, second and third sub-links and a crank member, in which the respective links are interlocked with corresponding parallel links, respectively. Accordingly, clutch means need not be disposed to all of the connection shafts of the links, but they may be located close to a pivot at a relatively low position, to a connection shaft connecting the first auxiliary link with the first sub-link and to a connection shaft connecting the second auxiliary link with the second sub-link. Thus, the links need not be operated by the respective heavy clutches. The present apparatus enjoys excellent operability, and such a structure is also advantageous from the standpoint of stability of the entire apparatus.
