Abstract
The present invention provides a new type inserted probe for cold therapy of liver cancer. Its bar portion is equipped with vacuum adiabatic layer and reflective adiobatic layer, so that it possesses reliable adiabatic property. Said invented product is applicable to various cold therapies having need of inserting probe into body, and can protect tumor-free tissue from low-temp. injury. Its chilling head and bar portion are connected by using removable mode, so that it is easy to change chilling head with different size and shape so as to meet requirements of different therapeutic goals.
Description
The present invention relates to a kind of new plug-in liquid nitrogen cryotherapy device, the plug-in type probe for cold therapy that particularly a kind of bar portion has heat-insulating property.
At present the probe for cold therapy of liver cancer of domestic and international application mainly contains two kinds of plate-like formula and plug-in types.Insertion type probe be mainly used in therapentic part deeply hepatocarcinoma.How the bar portion of existing insertion type probe does not possess perfect heat-insulating property, thereby passes one section no cancer liver parenchyma and implement at it and make the no cancerous tissue in this place be subjected to low temperature injury inevitably when freezing.
Secondly, the refrigeration head and the bar portion of existing insertion type probe for cold therapy of liver cancer combine as a whole, and same probe is difficult to adapt to the needs of different big or small oncotherapys.
Secondly, existing insertion type probe for cold therapy of liver cancer price is high, can not become disposable apparatus again, must be sterile-processed before using, however existing disinfectant measure is difficult to thoroughly stop the iatrogenic infection of disease.
Purpose of the present invention is to provide a kind of novel insertion to make cryoprobe, and its bar portion has reliable and stable heat-insulating property, in implementing the cold therapy process of inserting in the liver, non-cancer hepatic tissue is not caused low temperature injury; Between its refrigeration head and the bar portion is removable lining, selects the refrigeration head of different sizes and form when being convenient to treat different big or small tumor for use; It is simple in structure, and is cheap, can be used as disposable apparatus, also can be repeatedly used.In addition, still be applicable to that other need insert endoceliac cold therapy, as the cold therapy of malignant tumor such as rectal cancer, cervical cancer, simultaneously, also make the cold therapy of tumor in the abdomen such as hepatocarcinoma under the peritoneoscope, the cold therapy of intrathoracic tumor such as pulmonary carcinoma becomes possibility under the thoracoscope.
The objective of the invention is to be achieved through the following technical solutions:
A kind of is the plug-in type cold therapy device of ingredient by the bar portion with heat-insulating property, and the heat-insulating property of bar portion is by vacuum heat-insulating layer and reflective thermal insulation board and produce;
The terminal adsorbent of installing of bar portion interlinks with vacuum heat-insulating layer;
The terminal joint of installing of bar portion can link with the valve of vacuum pump suction;
Being connected between the refrigeration head of performance profound hypothermia effect and the bar portion is designed to detached type.
Connect with vacuum pump by the joint of valve, make bar portion parietal layer form vacuum layer through the vacuum pump suction with bar portion end.Implement when freezing, because the dual athermic effect in vacuum layer and reflecting layer, the tissue of having avoided contacting with bar portion is subjected to low temperature injury.Issuable minimum gas in the vacuum layer under the high cold state can be through adsorbents adsorb.If through being repeatedly used, negative pressure descends in the vacuum layer, can connect the vacuum pump repeat aspiration and recover the reliable heat-insulating property of bar portion through joint.The refrigeration head can be made into multiple length and form, and can adapt with various therapeutic purposes after bar portion is connected.
Below with reference to accompanying drawing, the present invention is described in further detail.
Accompanying drawing is the profilograph of concrete structure of the present invention.
With reference to accompanying drawing, the double-layer stainless steel pipe constitutes the bar portion (3) of cryoprobe.According to the vacuum insulation principle, between the two-layer stainless steel tube vacuum layer (4); According to the reflective insulation principle, wall is coated with around white membranoid substance outside the inner layer stainless steel tube, forms reflective thermal insulation board (5).Bar portion tail end is inserted adsorbent (6), to adsorb the minimum gas that produces in the vacuum layer under the high cold state (4).The joint (7) of bar portion tail end is connected with vacuum layer (4), can connect vacuum pump through this joint by valve, is convenient to aspirate at any time to avoid the being repeatedly used final vacuum heat insulation layer descend because of air accumulation makes heat-insulating property.If the present invention uses as disposable apparatus, then need not suction.The refrigeration head (1) of performance therapeutical effect is a detached type with the joint (2) of bar portion (3), is convenient to change the refrigeration head of different sizes, to adapt to the needs of different treatment objectives.
Claims (4)
1. one is the plug-in type cold therapy device of ingredient by the bar portion (3) with heat-insulating property, and the heat-insulating property that it is characterized in that bar portion (3) is by vacuum heat-insulating layer (4) and reflective thermal insulation board (5) and produce.
2. by the cold therapy device of claim 1 regulation, it is characterized in that bar portion end is equipped with adsorbent.
3. by the cold therapy device of claim 1 or 2 regulations, it is characterized in that bar portion end has the joint that can supply vacuum pump to aspirate.
4. by the cold therapy device of claim 3 regulation, it is characterized in that refrigeration head (1) and bar portion (3) junction (2) are detached type.
