Technical Field
The invention belongs to the field of medical equipment, and particularly relates to a coagulation-cutting synchronous integrated device for rapidly cutting prostate tissue and an operation and use method.
Background
The prostate is an important genitourinary organ of men, and related symptoms caused by hyperplasia of prostate tissue are very common in middle-aged and elderly men, the cause of the disease is mainly that the gradual enlargement of the prostate generates pressing and obstruction to the outlets of urethra and bladder, which are manifested as frequent micturition, urgent micturition, dysuria, nocturia and the like, and along with the progress of the disease, repeated urinary system infection, hematuria, vesical calculus and urine retention can be caused, and even the upper urinary tract can be damaged, so that the kidney is damaged. Therefore, active treatment is needed, and many patients have medical treatment that cannot be relieved or have related complications, and surgical removal of prostatic hyperplastic tissue is one of the necessary means. At present, the open surgery for removing the prostate has the factors of large trauma, much bleeding, more postoperative complications, long recovery time and the like, the clinical application is gradually reduced, the minimally invasive surgery mainly focuses on the Transurethral intracavity surgery, the classical method is Transurethral resection of the prostate (TURP), and the recent method is vaporizing resection, plasma, microwave, laser energy and technical means for removing or ablating the prostate tissue. However, the transformation and improvement of these methods do not significantly improve the surgery-related conditions and complications compared to classical transurethral resection of prostate, and TURP is still the "gold standard" for the treatment of prostate hyperplasia. Because patients needing excision are generally old men, basic diseases such as heart and lung diseases are more and serious, tissues of prostate are easy to bleed, the operation time is generally long, the requirements on preoperative conditions of the patients are relatively high, otherwise, the risks are high, particularly, related complications such as venous thrombosis and the like have fatality and the like, so that a plurality of patients lose operation opportunities, and the factors such as related complications of the operation, recovery delay, operation time and bleeding are obviously related. Therefore, how to effectively and rapidly remove prostate tissue and reduce bleeding is one of the key factors for surgical treatment and complications reduction.
Disclosure of Invention
