## Title
Needle for treating diseases

## Abstract

A hollow needle for removing unhealthy inclusions from organism is cooled by filling with a cooling medium by its cooling device and freezes an inclusion, the needle is then heated by it heating device to dislodge the inclusion, and thereafter the dislodged inclusion is withdrawn through a passage in the needle by its withdrawing device.

## Background
BACKGROUND OF THE INVENTION
The present invention relates to a needle for treating diseases for example, cancer, aids, polyps, prostate tumors, etc.
More particularly it relates to apparatuses and methods for treating diseases, which use freezing of unhealthy inclusions in an organism.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a needle for treating diseases for example cancer tumors, aids, polyps, prostate tumors, etc., which is a further improvement of the existing apparatuses.
In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a needle for treating diseases, comprising a hollow needle element having an interior; cooling means supplying a cooling medium into the interior of the hollow needle element and cooling the needle element and thereby freezing an unhealthy inclusion when the hollow needle element filled with the cooling medium is introduced into the unhealthy inclusion; means for heating the needle inserted into the interior of the needle in contact with the hollow needle element and heating the hollow needle element and thereby heating the unhealthy inclusion to dislodge it; and withdrawing means for withdrawing the unhealthy inclusion from an area in which it was frozen and including a withdrawing passage formed in the hollow needle element.
Another feature of the present invention resides, briefly stated, in a recirculating means connected with the cooling means and recirculating the cooling medium through the interior of the hollow needle element, electric source means electrically heating the heating means, and pump means connected with the passage and forcibly evacuation the frozen unhealthy inclusion from the passage outwards of the hollow needle element.
A further feature of the present invention resides in temperature sensing means sensing a temperature of said hollow needle element; means for adjusting a temperature of cooling in a cooling phase in response to a temperature sensed by the sensing means; and means for adjusting a temperature of heating in a heating phase also in response to a temperature sensed by the same sensing means.
The novel features which are considered as characteristic for the present invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

FIG. 2 is a view showing a cross-section of the needle for treating diseases of the present invention;



DESCRIPTION OF THE PREFERRED EMBODIMENTS
A needle for treating diseases in accordance with the present invention has a hollow needle element 1 which can be introduced into an organ with an unhealthy inclusion.
A cooling medium, for example Freon 2 is introduced into an interior of the hollow needle element 1 by cooling means including a cooling aggregate 3, a compressor 4 and a recirculating pipe 5. The cooling medium is supplied by the compressor 4 from the aggregate 3 through the pipe 5 into the hollow needle element 1, and the hollow needle element 1 is cooled to a very low temperature. The temperature of the hollow needle element and/or of the cooling medium is sensed by sensing means formed as a sensor S and can be adjusted to a desired temperature by adjusting means formed as a thermostat T. The cooled hollow needle element 1 introduced into an unhealthy inclusion freezes the unhealthy inclusion by subjecting it to a high level of cold in a cooling stage. The cooling medium heated in the needle flows back into the cooling aggregate to be cooled.
The needle is also provided with heating means formed as a heating device 6 which heats the hollow needle element 1 and thereby dislodges the frozen unhealthy inclusion from the area where it was frozen. The heating device 6 is supplied with power from, for example, an electric power source 7. The temperature of the hollow needle element and/or of the heating device is sensed by the sensor S and can be adjusted by the same thermostat T to a desired temperature.
The needle has withdrawing means including a through going passage 8 formed in the hollow needle element and connected with a pump 9. Under the action of the pump 9 the unhealthy inclusion can be withdrawn through the passage from the area when it was located and then outwards.
The hollow needle operates in the following manner:
During a cooling stage the cooling medium 2 is supplied into the interior of the hollow needle element 1 and the hollow needle element 1 cooled by the cooling medium is introduced into an unhealthy inclusion and freezes it. The heating device then heats the hollow needle element and the heated hollow needle element dislodges the frozen unhealthy inclusion from the area where it was located. The dislodged unhealthy inclusion is then withdrawn by the withdrawing means from the area through the throughgoing passage outwards of the needle.
All above-mentioned components required for carrying out of all above stages are provided in the same needle, and all stages (cooling, heating, withdrawing) are carried out by the same needle introduced into the unhealthy inclusion.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above.
While the invention has been illustrated and described as embodied in a needle for treating diseases, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, be applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.

## Claims
