Abstract
A surgical guide hub for implanting in an aperture formed in a skull and made along a trajectory to a brain target, wherein the guide hub comprises: a through-bore for delivering a device therethrough and along the trajectory; at least one first formation on an external surface for securing the hub within the aperture in a skull; and at least one second formation on the surface of the through-bore for securing a guide device, an implantable device, or a cap to the hub. Also provided are a jig for setting the depth of insertion of a surgical tool into a patient during surgery, and a method of preparing an operative length of a surgical tool.
Claims25
A jig for setting the depth of insertion of a surgical tool into a patient during surgery, the jig comprising:
- a tool aligning device;
- a representative datum representing a stereoguide datum;
- and
- a reference guide moveable relative to the representative datum to set a baseline length from the representative datum to a datum surface on the reference guide;
- wherein the reference guide comprises at least one offset from the datum surface configured to receive a surgical tool extending from the tool aligning device;
- and wherein the depth of insertion of the surgical tool when used in surgery on a patient is set on the jig by the distance from the representative datum to the offset;
- and
- wherein the tool aligning device comprises a bar including slots or grooves to receive generally elongate tools and direct their distal ends towards the reference guide.
A jig for setting the depth of insertion of a surgical tool into a patient during surgery, the jig comprising:
- a tool aligning device;
- a representative datum representing a stereoguide datum;
- a reference guide moveable relative to the representative datum to set a baseline length from the representative datum to a datum surface on the reference guide;
- and
- a stand to hold the jig up from an angle to the horizontal,
- wherein the reference guide comprises at least one offset from the datum surface configured to receive a surgical tool extending from the tool aligning device;
- and wherein the depth of insertion of the surgical tool when used in surgery on a patient is set on the jig by the distance from the representative datum to the offset.
