Abstract
Provided is a combinable electrode needle base structure in which a base to which electrode needles are coupled can be used in a combined or separated state to use the electrode needles according to the size and location of a lesion. In the combinable electrode needle structure, electrode needles are connected to the front side of an electrode needle base, and receive RF waves from RF (radio frequency) generator. The electrode needle base is divided into dividable bases to which the electrode needles are respectively coupled. When a lesion to be cauterized is large or cauterization should be concentrated, the dividable bases are combined and then used, and when a lesion is small or lesions are scattered, the dividable bases may be separated and then used.
Core Innovation
An RF ablation electrode needle base that can be reconfigured between a combined state and a separated state is disclosed. The electrode needle base includes an electrode needle base front side to which electrode needles are coupled so as to receive RF waves from an RF generator, and the electrode needle base is divided into multiple dividable bases for receiving the respective electrode needles.
Coupling parts are formed on separation surfaces of each dividable base. The coupling parts on the separation surfaces of one dividable base are coupled to the coupling parts on the separation surfaces of another dividable base such that the dividable bases are used together in a combined state, or decoupled to enable a separated state for use.
Widened parts are formed at both ends of each dividable base. When the dividable bases are combined, coupling tools are coupled to outer sides of the dividable bases in a manner such that the coupling tools cover and fasten the widened parts of the dividable bases to prevent separation.
A guide is also described to position and align electrode needles uniformly for insertion, and the guide includes guide stages of different heights and penetration holes to receive the electrode needles. Exemplary operating scenarios are described for using the electrode needle base in a combined state for large lesions and in a separated state for small scattered lesions.
Claims Coverage
The independent claim describes a combinable electrode needle base structure that can be used in either a combined state or a separated state by coupling or decoupling coupling parts on separation surfaces, with widened parts secured by coupling tools, and a dependent refinement describing a guide with different-height stages and penetration holes.
Combinable electrode needle base divided into dividable bases with coupling parts
The electrode needle base is divided into a plurality of dividable bases, each having coupling parts formed on separation surfaces so that coupling parts of one dividable base are coupled to coupling parts of another dividable base.
Reconfigurable combined state or separated state by coupling or decoupling separation-surface coupling parts
The combinable electrode needle base structure is used in a combined state by coupling the coupling parts of the separation surfaces of one dividable base to the coupling parts of the separation surfaces of another dividable base, or is used in a separated state by decoupling the coupling parts of the separation surfaces of one dividable base from the coupling parts of the separation surfaces of another dividable base.
Widened parts at both ends and coupling tools to prevent separation
Widened parts are formed at both ends of each dividable base, and when the dividable bases are combined, coupling tools cover and fasten the widened parts of the dividable bases on outer sides to prevent separation.
Guide with different-height stages and penetration holes
A guide is provided with guide stages of different heights and penetration holes formed to receive the electrode needles.
Overall, the claim coverage centers on a dividable electrode needle base with separation-surface coupling parts enabling combined versus separated states, secured by coupling tools over widened ends, and optionally refined with a guide having different-height stages and penetration holes for electrode needle positioning.
