View-finder for assisting implantation of e.g. pin in scaphoid of hand, has mounting unit mounting support in displacement relative to base, and fixation unit fixing support relative to base in position determined relative to base

摘要

The finder (1) has a defining unit (20) defining a space (22) defined by parallel plates in a plane and passing through a reference line (16), which is materialized on a support (14) by a band in a material opaque to radiation. A mounting unit (30) mounts the support in displacement relative to a base (10), where the support is made of a material transparent to radiation to x-ray a scaphoid (3). A fixation unit fixes the support relative to the base in a position determined relative to the base. A section of a spindle support and width of the space are equal to a section of a pin (2). The parallel plates and the spindle support are made of a material transparent to radiation.
