Definitions
- the present invention relates to electrosurgical equipment and more particularly to a disposable clipon device which may be attached to any conducting forceps to convert the forceps for use as an electrosurgical instrument.
- One method of making this procedure simpler is to provide a special forceps which incorporates the contacts to control the electrosurgical device through a system of relays.
- a forceps as shown, for example,
- Another device as illustrated in U.S. Pat. No. 2,827,056, uses a single conductor to carry both a high frequency current to the bleeder and a low voltage direct current used to power the control means.
- the electrosurgical apparatus can be made to discharge the high frequency current from the electrode into the body automatically when the electrode is touched to the body or the homostat.
- this device still requires that two devices be used, that is, the hemostat and the discharge electrode and in all cases it may not be desired to trigger the discharge as soon as the electrode is touched to the hemostat or the body.
- the present invention may be characterized by a disposable device for converting any conducting forceps into a discharge electrode of an electrosurgical device of the type wherein both the high frequency working current and the low voltage DC control current pass through a common conductor, the patient being in the control circuit.
- the device includes a switch terminal common to both the control and working circuits which is detachably attachable to a conducting forceps. The switch terminal is normally open and is closed upon squeezing the forceps to contact the switch terminal against a leg of the forceps.
- One object of the present invention is to provide means which may be detachably attached to an ordinary metal forceps to convert said forceps to an electrosurgical discharge electrode.
- Another object of the present invention is to provide a disposable lead and switch which can be clipped to one leg of a metal forceps for purposes of converting the forceps to a discharge electrode wherein the discharge occurs when the forceps are closed to contact the switch against one leg of the forceps.
- a further object of the present invention is to provide an electrode discharge control means which may be readily attached to a metal forceps, wherein both the control and working current are carried by a single conductor.
- FIG. l is a schematic view showing the disposable lead and clip of the present invention attached to a forceps
- FIG. 2 is a side view of the attachable clip portion
- FIG. 3 is a sectional view taken along lines 3-3 of FIG. 2.
- FIG. 1 shows schematically a patient generally indicated at 2 resting on a conductive patient plate 4.
- a lead 30 capacitively connects the patient plate to ground within an electrosurgical device 26.
- the hemostat or forceps member 6 is shown with its operative end 8 gripping a portion of the patient such as a bleeder which is to be cauterized.
- Attached to One leg 10 of the forceps is a clip-on member generally indicated at 12. This clip-on member is insulated from the body of the forceps and has a switch terminal 14 connected to a lead 16.
- Lead 16 is in turn connected to electrosurgical device 26 which has a circuit of the type illustrated in U.S. Pat. No.
- the clip-on device 12 is shown to include a body member 20 made of a nonconducting slightly resilient material such as plastic or plastic coated metal.
- a groove 22 is formed along one edge of the body member for attaching the member in clip-on fashion to a leg of the forceps.
- Lead 16 which is otherwise coated with insulation 24 is imbedded in the body member during the molding or forming process in a fashion which insures that the only portion of the lead which is exposed is terminal 14.
- lead 16 is connected to the forceps by clipping member 12 to one leg of the forceps as shown in FIG. 1.
- the other end of lead 16 is plugged into an appropriate electrosurgical apparatus 26 which utilizes a electrode discharge control circuit of the type shown in U.S. Pat. No. 2,827,056.
- Closing switch 28 closes the working circuit to supply the high frequency working current through lead 16 and the tips 8 of the forceps to cauterize the bleeder. Opening the forceps to remove terminal 14 from against the oppposed forceps leg opens the control circuit and deenergizes the relay to open switch 28. When the surgical procedure is completed, the lead and clip-on member may be removed and discarded and the forceps sterilized along with the other surgical instruments.
- the present invention accomplishes its intended objects in providing a simple, inexpensive throw-away switch means for con verting any standard surgical forceps made of a conducting material to an electrosurgical discharge electrode.
- the switch means may be readily attached to one leg of the forceps and then is removed and discarded after use to permit sterilization of the forceps by conventional means.
- Means for discharging current into a human body including a surgical forceps made of electrically conducting material and having two opposed legs joined together at one end and adapted to be brought together at their said opposite ends by pressure applied to said legs, said forceps being connected to an electrosurgical circuit of the type having a direct current control portion, an alternating current work portion and means for triggering flow of said alternating current in said work portion when said control circuit portion is completed through said patient, the improvement comprising a disposable switch means for connecting said forceps to said electrosurgical circuit, said switch means comprismg: l
- a body member of an insulating material having a groove adapted to receive therein one leg of said forceps in snap-on fashion so that said body member is detachably attachable to said forceps;
