Improvements in Pliers for Surgical and other Purposes.
I, CAREL AUGUST HOEFFICHE, the Younger, of 94, Breestraat, Leiden, Holland,
Manufacturer, do hereby declare the nature of this invention to be as follows:--
This invention consists of a new pliers or tongs for surgical and other work,
the jaws of which operate in parallel lines instead of approaching at an angle
like those of ordinary pliers which allows it to grip vessels or other objects in
the most effective and desirable manner.
The pliers are composed of two parallel arms forming the jaws one of which
is fixed and carries two pairs of guide-bars inside which the other arm, which
is moveable works to and fro.
At the end of one pair of the said guide-bars is pivotted a lever, jointed to a
sliding bar of special shape, the end of which engages with a roller mounted at
the end of the other pair of guides. This sliding bar rests on one side against
the moveable arm which is kept apart from the fixed arm by a spring.
The method of using the pliers is as follows:-
-
When the lever is lowered the sliding bar is simultaneously pressed against
the moving arm of the pincers, and its back which is rounded and enlarged,
to act as a wedge passing under the roller, forces the two jaws to draw close
together in parallel planes.
In order to hold the lever and the pincers in the closed position the latter is
furnished with a locking device consisting of a bar, jointed to an excentric,
furnished with a handle.
The fixed arm of the pincers terminates in a fork inside which is placed a small
roller. The excentric is supported by this roller and is turned by means of the
handle which engages in the fork of the fixed arm.
The excentric draws the lever before named by means of the jointed rod towards
the said excentric and maintains this lever in the closed position.

by the following statement:-
The present invention relates to new pliers for surgical or other work, the
jaws of which operate in parallel lines, instead of approaching each other at
an angle, as is the case in ordinary instruments of this nature and thus the
bodily organs, vessels, or other objects can be more firmly gripped than has been
possible with the instruments hitherto in use. The accompanying drawings
give, by way of example, one form of execution.
The pliers consist of two parallel members, forming the jaws, a and b. The
member is fixed and is provided with guide-bars e, in which the movable
member works to and fro. At the end e of one of the guide-bars e, a bent
lever is pivoted. This lever is jointed at g to a sliding-bar h, shaped like a
wedge, the end of which engages with a roller i, mounted at the end of the
other guide c.
This slide-bar rests on the movable member b, which is normally kept apart
from the fixed arm a, by a spring d.
The method of using the pliers is very simple and may be described as follows:-
When the lever f is lowered, the sliding-bar g is simultaneously pressed against
the moving arm 6 of the pincers and its wedge-shaped end is made to pass under
the roller i, bringing the two jaws together in parallel planes.
In order to hold the lever f and the pincers in the closed position, the latter
is provided with a locking device consisting of a bar k, jointed to an excentric 7,
furnished with a handle m.
The fixed arm a terminates in a fork, inside which is placed a small rollern.
The excentric is supported by the roller and is turned by means of the
handle m, which engages in the fork o.
The excentric draws towards itself the lever f, by means of the rod k, and
maintains this lever in the closed position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Pliers for surgical purposes, having a movable arm which is guided to operate
in a line parallel to the fixed arm and which is pressed against the latter by
means of a wedge-shaped slide-bar, actuated by a lever substantially as herein-
before described.
