Description
FIG. 1 is a perspective view of a hollow needle which is ground at
its front end (shown to the right in FIG. 1) to form a conical
taper and has an angled grip at its rear end;
FIG. 2 is a perspective view of a mandrel (which is loosely
introducible into the hollow needle of FIG. 1 as shown in FIGS.
21-24);
FIG. 3 is a perspective view of a first form of osteological drill
bit with an exterior hexagonal configuration at its rear end (shown
to the left in FIG. 3 and used for example for attaching a wrench
or for connecting a drill) and with a flat cutter blade at its
front end;
FIG. 4 is an enlarged fragmentary side elevational view of the
osteological drill bit of FIG. 3;
FIG. 5 is a rear end view of the osteological drill bit of FIG. 4
(viewing FIG. 4 from the right);
FIG. 6 is a front end view of the osteological drill bit of FIG. 4
(viewing FIG. 4 from the left);
FIG. 7 is a fragmentary bottom plan view of the osteological drill
bit of FIG. 4;
FIG. 8 is a perspective view of a second form of osteological drill
bit with an exterior hexagonal configuration at its rear end (shown
to the left in FIG. 8 and used for example for attaching a wrench
or for connecting a drill) and with a flat cutter blade at its
front end;
FIG. 9 is an enlarged fragmentary side elevational view of the
osteological drill bit of FIG. 8;
FIG. 10 is a rear end view of the osteological drill bit of FIG. 9
(viewing FIG. 9 from the right);
FIG. 11 is a front end view of the osteological drill bit of FIG. 9
(viewing FIG. 9 from the left);
FIG. 12 is a fragmentary bottom plan view of the osteological drill
bit of FIG. 9;
FIG. 13 is a perspective view of a manually operable osteological
instrument for emplacing a stimulation electrode having a tip which
is screwed into the bone (by manual turning of the knurled disk at
the rear end of a small torsion transmitting tube shown in detail
in FIG. 14);
FIG. 14 is a fragmentary enlarged side elevational view of the
osteological instrument of FIG. 13 (and showing the knurled disk at
its rear end, at the right in FIG. 14, and showing an interior
hexagon at its front stimulation-electrode-engaging end);
FIG. 15 is an end elevational view of the osteological instrument
of FIG. 14, viewed from its front end;
FIG. 16 is an end elevational view of the osteological instrument
of FIG. 14, viewed from its rear end;
FIG. 17 is a perspective view of an osteological instrument for
forming a site in the bone for receiving a stimulation electrode
and comprising the hollow needle implement of FIG. 1 and a drill
bit such as that of FIGS. 8-12;
FIG. 18 is a perspective view of an osteological instrument for use
in emplacing a stimulation electrode, consisting of the hollow
needle implement of FIG. 1 and the electrode driving tool of FIGS.
13-16, operatively associated with a stimulation electrode at the
frontal end (to the right in FIG. 18) and showing an insulated
electrical conductor (to the left in FIG. 18 and which extends
within the electrode driving tool and connects with the stimulation
electrode tip as illustrated in FIG. 19);
FIG. 19 is a partial enlarged view showing the frontal end of the
electrode driving tool of FIG. 14 being placed over the insulated
electrical conductor such that movement of the driving tool toward
the tip of the stimulation electrode will result in driving
interengagement between an exterior hexagonal nut portion of the
stimulation electrode and the interior hexagonal socket portion at
the frontal end of the driving tool, (behind the nut portion of the
stimulation electrode is a sleeve for fastening to the insulated
electrical conductor which is electrically connected with the
electrode tip);
FIG. 20 is a frontal end view of the stimulation electrode seen in
FIG. 19;
FIG. 21 is a perspective view of an osteological instrument for
pressing through the soft tissue up to the bone (such instrument
comprising an assembly of the components of FIGS. 1 and 2);
FIG. 22 is a side elevational view of the osteological instrument
of FIG. 21;
FIG. 23 is a top plan view of the osteological instrument of FIG.
21;
FIG. 24 is a front elevational view of the osteological instrument
of FIG. 21;
FIG. 25 is a perspective view of a second form of the osteological
instrument of the present invention (utilizing the hollow needle
implement of FIG. 1 which is also used in the form of osteological
instrument shown in FIGS. 21-24, and also utilizing the drill bit
of FIGS. 3-7);
FIG. 26 is a side elevational view of the instrument of FIG.
25;
FIG. 27 is a bottom plan view of the instrument of FIG. 25 (but
showing a driving means engaged with the rear end of the drill
bit);
FIG. 28 is a front elevational view of the instrument of FIG.
25;
FIG. 29 is a perspective view of a third form of the osteological
instrument of the present invention (utilizing the hollow needle
implement of FIG. 1 which is also used in the forms of osteological
instrument shown in FIGS. 21-24 and FIGS. 25-28, and also including
the electrode driving tool of FIGS. 14-16);
FIG. 30 is a bottom plan view of the instrument of FIG. 29;
FIG. 31 is a side elevational view of the instrument of FIG. 29;
and
FIG. 32 is a front elevational view of the instrument of FIG.
29.
