Description
Technical field
This utility model relates to and is used for the heater element that cryosurgery is protected normal structure; be particularly related to a kind of utilize laser heater, infrared heater, radio heater, microwave applicator or ultrasonic heater to human normal tissue heat be used for cryosurgery prevent the frosted irradiated heat device of normal structure, protect it to avoid low temperature injury thereby the human normal tissue that stands to lower the temperature is implemented heating.
Background technology
Minimally invasive medical is one of forward position of medical science and technology development both at home and abroad at present, and relevant art has become the commanding elevation in the advanced armarium of developing market.Cryogenic target is to surgical operation a kind of quite effectively new invasive physiotherapy of emerging in recent years of oncotherapy aspect just, its principle is to impel the lesion tissue fast cooling, freeze and melt by the freezing of fine probe of getting involved human body, produce a series of irreversible damages, thereby reach the purpose of eliminating focus.It can replace excision, need not sew up, and has that analgesia, hemostasis and minimizing are hemorrhage, a response light, safe and can prevent advantages such as tumor diffusion.So, in the short time, the cryosurgery operation is expanded fast and is applied to nearly all clinical tumor subject, as position tumor treatment (Hua Zezhao such as oral cavity, skin, rectum, liver, stomach, lung, mammary gland, prostate and brains, Ren Hesheng, the low-temperature biological Medical Technology, Beijing: Science Press, 1994; Liu Jingang, Liu Zuobin, hypothermal medicine, Beijing: People's Health Publisher, 1993), particularly for the very strong bulk tumor treatment of Drug resistance, the superiority of this method is more outstanding.
Cryogenic target is to facilitate lesion tissue to freeze, damage and necrosis to operating purpose, but must guarantee that again perilesional normal structure still is on the solidification point, unlikely frost bitten simultaneously.Though by optimization and imaging monitor The Application of Technology to freezing parameter (as cryoprobe size, cryoprobe quantity and on position etc.), cryosurgery has been obtained good effect on a lot of tumor treatment, but to some shape or baroque organ, present means are still unsatisfactory.The notion of heat protection is suggested just in this case.Along with cryogenic target is applied to more and more to surgical operation in the treatment of human body deep tumor, hot protection problem becomes more and more important.
At present thermal protection system all to around the tumor or inside tumor vitals parts protect.And in cryosurgery,,, brought very big challenge to heat-insulating technique because the demand cryoprobe size of Wicresoft is more and more littler though the cryoprobe knife bar has adopted provision for thermal insulation, the leakage heat of knife bar is can not be uncared-for in the real process.In addition, in the operation process, cold also can be delivered to the skin histology along journey from end of probe along metallic walls, and finally causes cold injury.Therefore, if do not take protective measure or protective measure improper, in cryosurgery, will inevitably cause cold injury to the tissue around the knife bar.This rehabilitation to cancer patient is very disadvantageous.
At above-mentioned situation, this utility model provide a kind of be used for cryosurgery prevent the frosted irradiated heat device of normal structure, can overcome above-mentioned deficiency to a certain extent.This irradiated heat device can make along the journey normal structure by the control heating intensity easily and be protected, and it is independent of cryosurgery equipment, can not have influence on the use of other equipment.
Summary of the invention
The purpose of this utility model be to provide a kind of be used for cryosurgery prevent the frosted irradiated heat device of normal structure; Its response speed is fast, simple in structure, cost is low, operates very easyly, can be used with existing cryosurgery equipment, realizes the requirement of invasive operation.
The technical solution of the utility model is as follows:
This utility model provides be used for cryosurgery prevent the frosted irradiated heat device of normal structure, comprising: the irradiation formula heater 1 of at least one 1-30W,
The heating intensity controller 4 that is electrically connected with described irradiated heat device 1 by cable 3;
In order to measure the temperature sensor 7 of body local tissue temperature; And
The data acquisition unit 6 that is electrically connected with described temperature sensor 7;
The computer 5 of one real-time monitoring that is electrically connected with described heating intensity controller 4 and described data acquisition unit 6 respectively and control tissue variations in temperature.
Described irradiation formula heater 1 is by laser heater, infrared heater, radio heater, microwave applicator or ultrasonic heater.
The cryosurgery probe that uses in described irradiation formula heater 1 and the cryosurgery structure that is combined into one.
As shown in Figure 1, irradiation formula heater 1 can be independent of cryosurgery probe 2 and be provided with separately, can be laser heater, infrared heater, radio heater, microwave applicator or ultrasonic heater.Irradiation formula heater 1 is electrically connected with heating intensity controller 4 by cable 3, and controls by computer 5.Work effect of the present utility model depends on the temperature of tissue to be protected, therefore, at tissue regions to be protected temperature sensor 7 is installed, and is connected with computer 5 by data acquisition unit 6.The temperature information of computer 5 by collecting; according to corresponding temperature value heating intensity controller 4 is regulated and control, adjusted the heating power of irradiation formula heater 1, thereby both protected normal structure; make its unlikely frost bitten, prevent superheated (causing its burn) again.Particularly, if normal structure temperature to be protected is low excessively, then strengthen heating power; Otherwise, then reduce heating power.
The another kind of structure of the irradiated heat device that accompanying drawing 2 provides for this utility model and the overall structure sketch map of corollary system thereof.Wherein, irradiation formula heater 1 is designed to one with cryosurgery probe 2, and this situation generally adopts the laser heater mode, and concrete design can be introduced LASER Light Source by fibre bundle, and fibre bundle then is integrated with the cryosurgery probe.Other technical scheme is with situation shown in the accompanying drawing 1.Except that the laser instrument heating, also can adopt other as heaters such as infrared heater, radio heater, microwave applicator, ultrasonic heater.
Certainly, the combination of irradiated heat device and cryoprobe is not limited to above scheme, variation more, such as, can be at focus shape and required ice hockey size in the treatment, with 1 to 30 piece of micro type radiant type heated probe be inserted into cryoprobe around and be definite shape and arrange, so, by means of the congelation of its space radiation heat effect and cryoprobe, can form complicated heating and freezing zone at lesions position, this conformal therapy for tumor has crucial meaning.
In sum, this utility model is realized be used for cryosurgery prevent that the frosted irradiated heat device of normal structure compact conformation is simple, heat protection effect is remarkable, has the very high ratio of performance to price.Existing cryosurgery probe adopts the method for vacuum heat-insulation mostly, and effect of heat insulation has reached its limit basically, but because leakage heat still can cold injury probe rod (inoperative position) normal structure on every side.Therefore, strengthen its heat-proof quality by technological improvement and do not had too big practical significance.Directly utilizing existing cryosurgery equipment, introduce irradiation formula heating system normal structure is carried out the heat protection, avoid being subjected to cryolesion along the journey health tissues, then is crucial part of the present utility model.The utlity model has simple in structurely, can not increase too much cost, operate advantages such as very easy, in cryosurgery development from now on, will have important application.
