Endoscope used for prostate operations

Abstract

The invention discloses an endoscope used for prostate operations, which comprises an endoscope body, wherein a light source port and an observation mirror are installed on the endoscope body. The endoscope is characterized in that the endoscope body is perpendicular to the observation mirror; a closer and an anti-reflux sealing cap are sequentially connected at the rear part of the endoscope body; a cavity on which changeable surgical instruments are put is arranged in the endoscope body; a treatment channel for the surgical instruments to pass through is connected at the front part of the endoscope body; and two carbon dioxide inlet valves are arranged at the front part of the endoscope body. The closer is provided with more than three pore canals for the surgical instruments to pass through for operation. The endoscope can be used in prostatectomy, resection of bladder tumors, vesical diverticulectomy, ureterocystostom and the like, and has the good effects that the endoscope can provide the doctor with a clear picture of the affected part before the operation, and with the endoscope, the doctor can operate with both hands to finish the highly difficult operations of resection, suture and the like, thus providing convenience for the doctor to conduct medical operations.

Description

Technical field [0001] The invention relates to a minimally invasive surgical medical equipment, in particular to an endoscope for prostate surgery. Background technique [0002] In the past 70 years, minimally invasive techniques of transurethral resection using transurethral resection have been used for bladder tumor diseases and prostate hyperplasia diseases. Called transurethral resection microscope. The scope uses a circular electrocutter under peeping to cut tissue one by one, and has electrocoagulation effect. Observation of the visual field is achieved by infusion of 5% mannitol or 5% glucose. In the past two decades, more than 95% of hospitals at home and abroad have adopted this method as the "gold standard" for the treatment of benign prostatic hyperplasia, and have basically abandoned open surgery for the treatment of benign prostatic hyperplasia. [0003] However, this "gold standard", for example, the current resection surgery has the following shortcomings: 1. A l...

[0003] However, this "gold standard", such as the current resectoscope surgery, has the following disadvantages: 1. It requires a large amount of expensive lavage fluid, and a prostate resection operation requires about 30,000 to 40,000 ml; 2. Intraoperative bleeding , easy to dissolve with lavage fluid, resulting in blurred vision, frequent water release and irrigation, which not only wastes a lot of water quality, but also increases the pressure in the bladder due to a large amount of perfusion fluid during the operation, which is prone to water intoxication and endangers life; 3. Liquid perfusion cannot be controlled The pressure in the bladder frequently makes the bladder high and low, which has adverse effects on the hemodynamics of the whole body; 4. The water used in the operation often contains viruses and bacteria, which will cause environmental pollution if it overflows into the operating room or flows into the sewer, and even causes medical staff Pollution

[0004] However, the existing prostate surgery often requires the use of electric cutting rings, and the application of electric cutting rings has the following problems: 1. For resection of benign prostatic hyperplasia, electric cutting rings need to be cut one by one, and a blood vessel needs to be cut multiple times before hemostasis; 2. Ring cutting requires the operation of digging out, and the prostate capsule is thin. In order to prevent cutting through the prostate capsule, it is difficult to completely remove the hyperplastic glands with an electric cutting ring; 3. The remaining glands are the root of long-term urinary tract infections; 4 There may be serious complications such as cutting through the bladder neck, cutting through the prostate capsule and damaging the rectum

5. The resection tissue is strip-shaped, and it is not easy to distinguish the pathology after the operation. Excision of a large number of strips increases the workload of pathological department screening

[0005] Resection of bladder tumors; 1. Different parts of the bladder due to tumor growth, such as the posterior wall, the junction of the anterior and posterior walls, etc., are difficult to operate; 2. Tumors are resected one by one, and it is difficult to completely resect when the tumor invades the deep muscle layer ; Easy to cut through the bladder and change to open surgery; 3 It is more difficult to completely remove the tumor when there is obturator nerve reflex

It is difficult to confirm whether the tumor base is completely resected pathologically after resection of the tumor; 4. At present, the electrocution ring cannot be sutured in the bladder, making the operation a single operation, and it is impossible to use one device to treat other diseases in the bladder
