Embodiment 1

[0034] Such as figure 1 As shown, the present invention provides a cold and hot probe device for combined cold and hot treatment of tumors, its structure is as follows: it includes:

[0035] A low-temperature pressure vessel 1 with a booster 3 inside and a low-temperature working medium 2 inside;

[0036] One end is placed in the low-temperature working medium 2 in the low-temperature pressure vessel 1. The low-temperature working medium transmission pipe 5; The first heat-insulating lumen 51 on the outer wall; the first heat-insulating lumen 51 is a vacuum lumen or a lumen with a built-in heat-insulating material; A cryogenic fluid valve 4 is installed in the lumen;

[0037] A probe rod 7 connected to the other end of the low-temperature working medium transmission pipe 5; , the second heat-insulating lumen 73 set on the outer wall of the first return pipe 72 and the first electric heating element 74 set on the outer wall of the second heat-insulating lumen 73; the second ...

Embodiment 2

[0049] Figure 4 It is a structural schematic diagram of a cold and hot probe device used for combined cold and hot treatment of tumors in this embodiment.

[0050]The structure of this embodiment is basically the same as that of Example 1, the difference is that the cold and hot probe device used in this embodiment for the combination therapy of tumors adopts a detachable design; in clinical practice, for deep tumors, based on intervention Minimally invasive surgery performed by human probes generally requires percutaneous puncture; if the probe adopts a detachable design, it will undoubtedly greatly increase the flexibility of the doctor's operation during the puncture process, and facilitate more accurate surgery; this implementation In this example, it is only necessary to divide the low-temperature working medium transmission tube 5 into two parts near the handle 6 , and then connect them through the quick connector 13 . Pipeline quick connectors are a mature technology ...

Embodiment 3

[0052] The structure of this embodiment is basically the same as that of Embodiment 1; the difference between the two is that in this embodiment, the low-temperature pressure vessel 1 no longer uses electric heating to boost the pressure, but uses a self-pressurized low-temperature pressure vessel;

[0053] Self-boosting low-temperature pressure vessels (such as self-boosting liquid nitrogen tanks) are available on the market. The boosting principle is to draw part of the liquid nitrogen from the liquid nitrogen tank through a side pipe, and exchange heat with air through a coil heat exchanger, and then Vaporization, thereby increasing the pressure in the container; Compared with the electric heating boost method, the advantage of the self-pressurization method is that it will not increase the temperature of the liquid nitrogen in the container, so that on the one hand, it can obtain the lowest temperature closer to the liquid nitrogen temperature. Cryotherapy temperature, on t...

Abstract

The invention discloses a cold and hot probe device and particularly relates to a probe device for cold and hot combination therapy by electric heating and liquid nitrogen refrigerating, which is suitable for treating various solid tumors. The cold and hot probe device comprises a low-temperature pressure vessel, a low-temperature working medium, a booster, a low-temperature fluid valve, a low-temperature working medium transport tube, a handle, a probe pole, a probe head, an electric heating element, a temperature sensor, a data acquisition / control unit, a DC power supply module, a computer and the like. The invention can cool and heat the probe head conveniently so as to implement the cold and hot combination treatment and prevent normal tissues around the probe pole from being frozen and damaged in the cooling process. The invention has the advantages of simple structure, low cost, good controllability, high safety, convenient use and the like.

Description

technical field [0001] The present invention relates to a cold and heat treatment probe used in combined cold and heat treatment of tumors, in particular to a cold and hot probe device for combined cold and heat treatment of tumors which is heated by an electric heating element; The electric heating element inside or on the surface of the probe, on the one hand, can prevent the normal tissue along the way caused by the heat leakage of the probe rod during the freezing process, and on the other hand, can quickly heat the tumor tissue after the cryotherapy stops. Background technique [0002] Technological research around tumor treatment has always been one of the major topics of concern to the biomedical engineering circles at home and abroad. In this regard, minimally invasive interventional physical therapy is becoming the forefront of developments in the field of medical devices. Among various minimally invasive treatment techniques for tumors, cryotherapy and hyperthermi...
