초록 ▼

A portable, thermal cauterizing forceps device for use in surgery. The device incorporates a pair of ceramic heater elements mounted within the tips of the tines of a forceps. The forceps is used to grasp tissue or blood vessels and apply heat to effect cauterization. The forceps instrument can incorporate a battery and control electronics. The thermal-forceps is of a self-contained wireless, handheld disposable design. The forceps handpiece can be connected to an external power source. The forceps can incorporate a set of rapidly heating ceramic heater elements that may be composed of silicon nitride. An LED provides the operator feedback as to the operating level of the heaters and/or battery reserve. The forceps can include a rechargeable power supply, variable control of the heater temperature, as well as a, digital display of the tip temperature.

1. A method for sealing and dividing blood vessels or thermocauterizing tissue with surgical forceps that include a forceps body and a pair of elongate tine members mounted to and extending from the forceps body to respective opposed free end tip portions spaced from the forceps body, the method comprising: electrically connecting power source leads to a power supply, at least one of said tip portions of the tine members comprising a heater element connected to the power source leads and said heater element having a flat, gripping and heating surface defined on an inner facing surface of said at least one of said tip portions;moving the tine members in a resilient compressible manner between a normally open position wherein the tine members are disposed in an aligned and spaced-apart relationship and a squeezed closed position wherein the tip portions of the tine members are disposed in a confronting abutting relationship;activating the heater elements to heat the flat gripping and heating surfaces thereof to a tissue cauterizing or blood vessel sealing temperature;supplying a high initial current to the heater element for rapid heat and then supplying a reduced current to said heater element for maintenance of the heat; andsqueezing together the tine members toward the squeezed closed position to grippingly, squeezably, engage tissue to be cauterized or a blood vessel to be sealed between the flat gripping and heating surface of said heater element and the opposed tip portion. 2. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising applying substantially uniform pressure and heat to a tissue gripped between the gripping and heating surfaces. 3. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising: indicating an operative state of said heater element;measuring, with a circuit board, a battery power reserve or supply voltage and an internal resistance and a temperature of said heater element; andindicating whether the battery power reserve or supply voltage and the internal resistance and the temperature of said heater element falls within predetermined operational limits. 4. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising electrically connecting a switch to the heater element and the power source leads and automatically turning on the heater element to heat the flat gripping and heating surface to an elevated tissue cauterizing or blood vessel sealing temperature as the tine members are moved from the normally open position to the squeezed closed position. 5. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising connecting a rechargeable battery to said power source leads. 6. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising connecting a battery to said power source leads. 7. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising connecting an external power supply to said power source leads. 8. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising receiving and holding the forceps body in a heat-resistant holster assembly. 9. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising varying an initial resistance of a heater circuit to obtain heat rapidly. 10. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising mounting each of said tine members of said pair of elongate tine members to opposite sides of a neoprene spacer for a spring effect. 11. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising terminating the supply of current to the heater elements when the tip portions of the tine members are released from their confronting abutting relationship. 12. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 1, further comprising emitting an audible sound from the forceps indicating an operational condition of the forceps. 13. The method of sealing and dividing blood vessels or thermocauterizing tissue according to claim 12, wherein the audible sound indicates whether the heating elements are at a normal operative temperature for effective cauterization.
