Description
Technical Field
The invention belongs to the field of medical appliances, and particularly relates to a human body natural cavity channel heat preservation system and a heat preservation catheter.
Background
The incidence rate of tumors in China is in a trend of rapid rise year by year, and especially, most of middle and late stage tumors, advanced patients and accompanying diseases are not suitable for surgical excision. The ablation is a treatment method for inactivating tumor lesion tissues in situ by adopting modes such as freezing or heating tumors, has the characteristics of minimally invasive or noninvasive, and has wide application in tumor treatment.
Ablation includes cryoablation (argon helium freezing, liquid nitrogen freezing, carbon dioxide freezing, laughing gas freezing, etc.), thermal ablation (radio frequency ablation, microwave ablation, laser ablation, ultrasonic focus ablation, infrared ablation, electrothermal ablation, etc.), and other localized ablation methods (e.g., cryogenic plasma, ozone, etc.). Most ablative procedures inactivate tumor tissue by the cold and hot effects.
The cold and hot ablation of tumors in close proximity to or surrounding the natural human body cavity (such as the airway, the alimentary canal, the urinary tract, the genital tract, the nasal cavity and the like) often causes frostbite or burn of the natural human body cavity; or the tumor is not thoroughly ablated in consideration of the damage of the body cavity. The current common method relies on image positioning to avoid the damage to the natural cavity of the human body, but has the disadvantages of high operation difficulty, more complications and high tumor residue.
In the case of prostate cancer ablation, since the urethra is completely wrapped in the prostate tissue, cold or hot ablation for the prostate gland tends to cause a certain degree of frostbite or burn to the urethra and bladder neck and urethral sphincter involved in urination, causing serious clinical complications such as urethral injury and urinary incontinence.
The relative position of the existing urethral insulation catheter in the urethra is unstable, which brings certain trouble to auxiliary treatment.
