Abstract
The utility model discloses a cold circulation electrode, aiming at the problem that the prior cold circulation electrode can not be used to treat a knob with a diameter of more than 3cm. The utility model comprises a handle (1) with a cavity and is characterized in that at least three electrode needles (2) are connected to one end of the handle (1), the tail end of the electrode needle (2) is connected to the cable (5) through the cavity of the handle (1), the needle of the electrode needle (2) is a two-cavity needle made of an inner enclosing tube (3) and an outer enclosing tube (4), the cavity between the inner enclosing tube (3) and the outer enclosing tube (4) communicates with the water-in pipe (6) or water-out pipe (7), the cavity in the inner enclosing tube (3) communicates with the corresponding the water-out pipe (7) or the water-in pipe (6), the water-in pipe (6) and the water-out pipe (7) are all connected to the corresponding circulation water pumps through the cavity in the handle (1). The utility model successfully solves the problem of microwound treatment of knob of big diameter, and has the advantage of simple structure.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of assistive device that utilizes radio frequency heat treatment tumor, specifically a kind of cool-tip electrode.
Background technology
As far back as eighties of last century the fifties, radio-frequency technique just is applied on the clinical treatment of tumor.Because general electrode very easily makes overheated, the vaporization of tumor cell in therapeutic process, even generation eschar, thereby increased the biologic resistance of tumor cell, make radio-frequency current be difficult to " seeing through " tumor tissues, directly have influence on therapeutic effect, thereby radio-frequency technique is restricted at clinical treatment tumour.
People have invented cool-tip electrode for this reason, because in the therapeutic process, electrode obtains the cooling of water, the tumor tissues temperature is risen gradually, reach and solidify, make radio-frequency technique can be applied to clinical treatment tumour, if the diameter of tumor is greater than 3cm then therapeutic effect is not good when finding single electrode cool-tip electrode treatment tumor in recent years in clinical application, operative cycle is long, and the order that does not reach minimally-invasive treatment has.
Summary of the invention
The purpose of this utility model is can not be used for the treatment of the problem of diameter greater than the 3cm tumor at existing cool-tip electrode, designs a kind of new cool-tip electrode.
The technical solution of the utility model is:
A kind of cool-tip electrode, comprise the inner handle 1 of cavity body that is, it is characterized in that on an end of described handle 1, being connected with at least three electrode needle 2, the tail end of described electrode needle 2 links to each other with the cable 5 of the cavity body of passing handle 1, the needle body of electrode needle 2 is two-chamber needle bodies that an inner sleeve 3 and trocar sheath 4 are formed, the cavity that forms between inner sleeve 3 and the trocar sheath 4 links to each other with water inlet pipe 6 or outlet pipe 7, cavity in the inner sleeve 3 correspondingly links to each other with outlet pipe 7 or water inlet pipe 6, and described water inlet pipe 6 links to each other with corresponding water circulating pump with the cavity body that outlet pipe 7 all passes in the handle 1.
Described three electrode needle 2 are positioned on the concentric circular.
On the trocar sheath 4 of described electrode needle 2, be embedded with thermocouple 8.
On a section of described electrode needle 2 close handles 1, be provided with insulating protective layer 9.
The beneficial effects of the utility model:
This utility model has solved the minimally-invasive treatment problem of major diameter tumor, and simple in structure.
