The needle having been inserted and clamped,
the operator then inserts a finger into the
opening A of the frame A, and with his thumb
presses down upon the thumb-plate D' on the
end of the lever-arm D. This pressure of the
thumb will bear the lever-arm D downward,
and the stein E, carrying the cushioned block
F, will press the said cushioned block down
upon theflesh above the blood-vessel, and by
closing the same will prevent the flow of blood
during the operation.
A guard-cap b (shown in dotted lines) may
be provided to fit over the point of the needle
when the instrument is in use and prevent
the accidental injury of the operator. This
cap should be provided with a short chain by
which it is attached to the body or frame A
of the instrument, as shown in Fig. 1.
My instrument may be made, either in whole
or in part, of any suitable material desired,
but should preferably be of metal throughout,
except for the coveringof the pressure-block
F, which should be chaminois-leather or some
similar soft material.
The frame or body of the instrument may
be made either straight or arched, as desired,
and the size of the instrument may be varied
to meet requirements.
In Fig. 5 is shown a needle having a spear-
point. I may use this form of needle, if de-
sired, and it is preferable where a great
amount of pressure is necessary to close the
blood-vessel, in order that the point of the
needle may be more firmly held by the grip-
ping device.
Many modifications of my device might be
made which could be used without departing
from the spirit of my invention, and I there-
fore do not wish to limit myself to the exact
details described herein.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent of the United States, is-
1. In a surgical instrument of the character
described, the combination with a body or
frame, of a resilient needle hinged to one end
of said frame; a pair of pivoted jaws mounted
upon the opposite end of said frame for en-
gaging and holding the pointed end of said
needle; a block or shoe, and means mounted
on said frame for depressing said block or
shoe, substantially as described.
2. In a surgical instrument of the character
described, the combination with a body or
frame, of a resilient needle hinged to one end
of said frame; a pair of toothed jaws, arms
for opening and closing said jaws, and means
for holding said jaws closed, mounted upon
the opposite end of said frame for engaging
and holding the pointed end of said needle;
a block or shoe, and means mounted on said
frame for depressing said block or shoe, sub-
stantially as described.
3. In a surgical instrument of the character
described, the combination with a body or
frame, of a resilient needle hinged to one end
of said frame; a pair of pivoted jaws mountedupon the opposite end of said frame for en-
gaging and holding the pointed end of said
needle; a block or shoe; a lever-arm pivoted 70
upon said frame and connected to said block
for depressing the same, substantially as de-
scribed.
4. In a surgical instrument of the character
described, the combination with a body or 75
frame, of a resilient needle hinged to one end
of said frame; a pair of toothed jaws pivoted
at the opposite end of said frame for engaging
and holding the pointed end of said needle; a
block; a stem pivoted to said block; a lever 8o
pivoted to said stem and also pivoted to said
frame, for depressing said block, substantially
as described.
5. In a surgical instrument of the character
described, the combination with a body or 85
frame, of a resilient needle hinged to one end
of said frame; a clamping device at the oppo-
site end of said frame for engaging and hold-
ing the pointed end of said needle; a block; a
stem pivoted to said block; a lever pivoted to 9go
said stem and also pivoted to said frame, for
depressing said block; a curved arm on said
frame provided with ratchet-teeth on one side
thereof, and a thumb-catch on said lever
adapted to engage said ratchet-teeth and thus 95
hold said lever down, substantially as de-
scribed.
6. In a surgical instrument of the character
described, the combination with a body or
frame, of a resilient needle hinged to one end ioo
of said frame; a clamping device at the oppo-
site end of said frame for engaging and hold-
ing the pointed end of said needle; a block; a
stem pivoted to said block; a lever pivoted to
said stem and also pivoted to said frame, for 105
depressing said block; a curved arm on said
frame provided with ratchet-teeth on one side
thereof, and a thumb-catch on said lever
adapted to engage said ratchet-teeth and hold
said lever down; and a finger-grip in said iro
frame, substantially as described.
7. In a surgical instrument of the character
described, the combination with a body or
frame, of a resilient needle hinged to one end
of said frame; a pair of toothed jaws, arms for 15
opening and closing the same, and means for
holding said jaws closed, mounted upon the
opposite end of said frame for engaging and
holding the pointed end of said needle; a
block; a stem pivoted to said block and work- 120
ing in a guideway in said frame; a lever piv-
oted to said stem and also pivoted to said
frame, for depressing said block; a curved
arm on said frame provided with ratchet-teeth
on one side thereof, working in a guideway in 125
said lever; and a thumb-catch on said lever
adapted to engage said ratchet-teeth and hold
said lever down, substantially as described.
In testimony whereof I affix my signature
in presence of two witnesses.
