Definitions

  • the needle electrode 10 is used in electromyography in which it is desired to insert an electrode, in the form of a probe, into a patient to locate a particular muscle and then inject a medicine into that muscle.
  • the tubular hollow needle member 14 is electrically conductive and, as such, electrically stimulates all tissue that contacts the needle member 14.
  • needle electrode 10 is primarily suited for use in tissues that will not be damaged by contacting the electrically conductive needle member 14. Additionally, needle electrode 10 is not adapted for use as a cauterizing device.
  • FIG. 1 is a perspective view of a prior art needle electrode.
  • the cauterizing needle 100 described above is particularly useful in procedures involving passing a needle through vascular tissue.
  • One such method includes passing the cauterizing needle 100 through vascular tissue, insulating the tissue from the cauterizing shaft 120 of the needle 100, cauterizing the tissue solely via the tip 124 of the needle shaft 120, and either withdrawing or dispensing a substance or fluid via a syringe attached to the needle 100.
  • the method may be used to accomplish procedures such as, for example: sclera buckling surgery, fluid aspiration, and tissue biopsy.
  • the vascular tissue is the choroidal tissue of the eye and the substance withdrawn via the syringe is subretinal or vitreous fluid.
  • the cauterizing needle 100 is used to dispense or inject a substance via a syringe, the substance may be, for example, a medication and/or an anticoagulation agent.

Abstract

L'invention concerne des aiguilles de cautérisation comprenant une aiguille pourvue d'une tige d'aiguille creuse, électro-conductrice, et une gaine isolante disposée sur ladite tige conductrice. L'invention concerne également des méthodes d'utilisation de ladite aiguille de cautérisation. Une de ces méthodes consiste à faire passer une aiguille de cautérisation à travers un tissu vasculaire; à isoler ce tissu de la tige de cautérisation de l'aiguille; à cautériser le tissu uniquement au moyen de la pointe de la tige d'aiguille; et à retirer ou à administrer une substance par l'intermédiaire d'une seringue fixée sur l'aiguille. L'appareil et/ou la méthode selon l'invention permet de cautériser de manière sélective des tissus et/ou vaisseaux spécifiques, au moyen d'une seringue fixée sur ladite aiguille de cautérisation.
