Claims19
A surgical system, comprising:
- a surgical targeting device for assisting placement of an elongated guidance member in a bone, comprising:
- a bottom portion having a dome-shaped convex outer surface and comprising a guidance through-hole extending along a guidance through-hole central axis for receiving the guidance member;
- and
- a top portion configured to be gripped by a tool;
- a socket part of a ball and socket joint implant;
- and
- a ball part of the ball and socket joint implant, the ball part comprising:
- a head,
- a shaft extending from the head, and
- a stem which is capable of receiving at least a portion of the shaft of the ball part;
- wherein the top portion of the surgical targeting device and the portion of the shaft of the ball part capable of being received by the stem have corresponding outer dimensions capable of being received in the stem,
- wherein the bottom portion of the surgical targeting device fits into a volume defined by outer dimensions of the socket part of the ball and socket joint implant.
A surgical targeting device sized and configured to be temporarily placed in the trapezium bone for assisting placement of an elongated guidance member in the trapezium bone, the surgical targeting device comprising a monolithic body having:
- a bottom portion having a dome-shaped convex outer surface and comprising a guidance through-hole extending along a guidance through-hole central axis for receiving the guidance member;
- and
- a top portion configured to be gripped by a tool, the top portion comprises a shaft extending from the bottom portion,
- wherein the guidance through-hole extends along the guidance through-hole central axis through the bottom portion and the top portion,
- wherein the shaft is sized and configured to temporarily be inserted into a stem of an implant,
- wherein the bottom portion comprises at least one auxiliary through-hole extending through the bottom portion along an auxiliary through-hole central axis and spaced from the guidance through-hole, the at least one auxiliary through-hole being configured to receive an attachment member so that the device becomes temporarily engaged with the trapezium bone,
- wherein the elongated guidance member is a Kirschner wire (K-wire).
