ELECTROCOAGULATION GRASPING FORCEPS FOR TUBE STERILIZATION BY MEANS
OF BIPOLAR HIGH FREQUENCY HEAT RADIATION
Abstract
The invention relates to a electrocoagulation grasping forceps
for tube sterilization for the elimination of sick parts of the
tissue by means of punctiform and section-taking heat radiation
without damaging sound parts of the tissue.

Claims
I claim:
1. An electro-coagulation gripping forceps comprising two arms and
a jaw formed by oppositely disposed terminal parts on said arms,
for utero-tube sterilization with the aid of a high frequency
electromagnetic field generated between said parts by heating and
destroying a tissue portion lying between said parts, said forceps
comprising gripping segments on said arms including said terminal
parts, and an insulating layer disposed on the external surfaces of
said gripping segments terminating short of, for exposing, said
terminal parts of said gripping segments, whereby the intensity of
said high frequency electromagnetic field is substantially
localized near said terminal parts.
2. An electro-coagulation forceps for utero-tube sterilization with
the aid of a high frequency electromagnetic field, said forceps
comprising two electrically conductive arms electrically insulated
from each other, and including claw-like developed gripping
segments at one end of said forceps, said segments including
opposite terminal parts defining a jaw, a bow-like handle formed at
the other end of said forceps mechanically connecting said arms,
connecting means for electrically connecting said arms to an
electrical generator for producing the high frequency
electromagnetic field at said jaw, a tubular insulating shell
through which said arms pass for manual insulated support of said
forceps and an insulating layer disposed on the external surfaces
of said gripping segments terminating short of, for exposing, said
terminal parts of said gripping segments, whereby the intensity of
said high frequency electromagnetic field is substantially
localized near said terminal parts.
Description
SUMMARY OF THE INVENTION
The object of the invention is an electrocoagulation forceps for
the elimination of sick parts of the tissue and for the
sterilization of the tube by means of high frequency heat
radiation, the forceps being characterized by two rod-shaped arms
which are constructed as electric conductors and insulated against
each other and connected to each other at one side via a bow-like
handle and arranged in a tubular shell consisting of insulating
materials, each arm disposing of devices of connection to the pole
of a current source and the free ends of the arms being constructed
as jaw-shaped and insulated grip-sections, the end sections lying
opposite each other being free from insulations.
The drawing shows the object of the invention as an example.
No. 10 shows a coagulation grasping forceps consisting of two
rod-shaped arms 11, 12 which are connected to each other at one
side via a bow-like handle 13. The forceps arms 11, 12 which are
composed of insulated electric conductors are arranged in a tubular
shell 14 consisting of insulating materials, the free arms of the
forceps together with the bow-like handle 13 protruding from one
end of the tubular shell, whereas the other two ends of the forceps
which protrude from the other end of the tubular shell have also
insulated and jaw-shaped grip sections 15, 16 the end sections 15a,
16a of which lying opposite each other being reinforced and free
from insulations. The two arms 11, 12 of the forceps are insulated
against each other in the handle 13 at No. 17. Furthermore, the two
arms 11, 12 dispose of devices given at 18 and 19 for the
connection of cables which are connected to a current source so
that arm 11 forms the + pole and arm 12 the - pole.
According to a further feature of the invention the grip sections
15, 16 are, only towards the outside, provided with an insulating
layer shown at 20, 21 so that the heat radiation can only become
effective in the space enclosed by the grip sections 15, 16.
After the part of the tissue which has to be eliminated is seized
by means of the free end pieces 15a, 16a of the grip sections 15,
16, forceps 10 is connected to a current source and heat is
produced because of the resistance existing between the two end
pieces 15a, 16a, said heat being used for destroying the tissue
part which has to be eliminated. There is, however, also the
possibility to produce the free end pieces 15a, 16a out of
current-carrying material of high resistance so that a joulean heat
required for the elimination of the tissue parts can be produced.
Apart from a bipolar current supply there is also the possibility
to use the forceps itself as one of the two current-carrying
conductors, whereas the human body is the other pole.
The special advantage of the coagulation forceps lies in the fact
that only that part of the tissue which has to be eliminated is
seized and exposed to heat radiation, whereas the other part of the
tissue cannot be destroyed or damaged. By the fact that the grip
sections have only an external insulation, only the part of the
tissue lying in the interior of the closed grip sections 15, 16 is
exposed to heat radiation.
