Abstract
The utility model relates to a disposable microwave radiator, which is characterized in that an outer conductor (6) which is used for limiting cauterization heating surface is arranged on the outer side of a radiation head. The outer conductor (6) is welded on an outer sleeve pipe (2), and the outer conductor (6) and the radiation head (3) are positioned on the same plane which forms an included angle ranging from 100 DEG to 145 DEG with a center line of the outer sleeve pipe (2). A coaxial inserting core (7) is arranged on the right end of the microwave radiator, and the right end is inserted on a socket which is arranged on the tail end of an instrument cable. The outer conductor (6) is a polygon, or a circle, or an ellipse. The utility model has the advantages of compact structure, small size, portability, low cost and convenient operation. In addition, the utility model is suitable for disposable use to avoid causing cross infection because of repeated use.
Description
Technical field
This utility model relates to the cautery that a kind of surgical operation is used, particularly a kind of disposable microwave radiometer.
Background technology
Existing microwave radiometer, contain a metal shell that volume is bigger, and winding body of using as radiant body, because the metal shell volume is bigger, blocks operator's sight line easily, influences the operator and observes the state that burns the zone and burn face, the medical microwave radiator that provides as Chinese patent CN 97110626.6, this irradiator design is very unreasonable, and cost is higher, repeatedly uses repeatedly and causes cross infection easily.
Summary of the invention
The purpose of this utility model is to provide a kind of cost to hang down disposable microwave radiometer easy to use, avoids reusing and causes cross infection.
A kind of disposable microwave radiometer, comprise coaxial cable 1, trocar sheath 2, radiation head 3, insulation sleeve 4 and 5, it is characterized in that: be provided with one in the outside of radiation head and be used to limit the outer conductor 6 that burns heating surface, outer conductor 6 is welded on the trocar sheath 2, and outer conductor 6 is in the same plane with radiation head 3, angle between the centrage of this plane and trocar sheath 2 is 100 °～145 °, a coaxial lock pin 7 is equipped with in the right part of microwave radiometer, and this right part is inserted on the socket of instrument cable end, and outer conductor 6 is a polygon, perhaps circular, perhaps oval, the microwave power of this microwave radiometer is 30～50w, and operating frequency is 2400～2500MHZ.
With prior art relatively, the utility model has the advantages that: background radiation device compact conformation, small volume and less weight, cost is lower, and is easy to use, is suitable for disposable use, avoids reusing and causes cross infection.
