Minimally invasive scalpel for urinary surgery tumors

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a minimally invasive scalpel for urinary surgery tumors. The scalpel comprises a scalpel body. A supporting ring is fixedly connected with the position, away from the scalpel point, of the top of the scalpel body. The inner diameter of the supporting ring is 0.6 to 0.8cm, and the supporting ring is made of a medical-grade material. One part of the bottom of the supporting ring is located in the scalpel body. According to the invention, the supporting ring is arranged; if the operation is unskilledor is in a highly-strained state, and when a person does not pinch the scalpel body tightly, due to the fact that the index finger is inserted into the supporting ring, and the index finger plays a role in preventing the supporting ring from falling off, the situation that the scalpel point of the scalpel body is passivated or people are injured due to the fact that the scalpel body falls off canbe prevented; the service life of the scalpel body is prolonged; and the safety of people is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a minimally invasive scalpel for urological tumors. Background technique [0002] As we all know, tumors of the urinary system are common and frequently-occurring diseases, such as bladder tumors, prostate tumors, and urethral tumors. One of the existing treatment methods is open surgical resection. Then open the patient's bladder or prostate, and then directly resect the tumor. The disadvantages of this method are that the patient suffers a lot, the operation is complicated, the treatment cost is high, the patient recovers slowly, and the treatment cost is high. Another method is to use microscopic surgery. Invasive scalpel—the resectoscope is used to resect the tumor. It is to enter the patient's prostate or bladder through the urethra for electrical resection of the tumor. The resectoscope is composed of a cystoscope and a minimally invasive scalpel. [0003] Due to t...

[0002] As we all know, tumors of the urinary system are common and frequently-occurring diseases, such as bladder tumors, prostate tumors, and urethral tumors. One of the existing treatment methods is open surgical resection. Then open the patient's bladder or prostate, and then directly resect the tumor. The disadvantages of this method are that the patient suffers a lot, the operation is complicated, the treatment cost is high, the patient recovers slowly, and the treatment cost is high. Another method is to use microscopic surgery. Invasive scalpel—resectoscope to resect the tumor, it is to enter the patient's prostate or bladder through the urethra for electrical cutting of the tumor, and the resectoscope is composed of a cystoscope and a minimally invasive scalpel

[0003] Due to the thinner thickness of the existing scalpel, when the intern holds the scalpel for training, due to unskilled operation or high tension, the scalpel will fall. If the scalpel falls on the ground, it is easy to cause The tip of the scalpel is blunted, which will seriously cause personal injury and affect the safety of use. In view of this, the present invention provides a minimally invasive scalpel for urological tumors, which can prevent the scalpel from falling , to ensure the service life of the scalpel and the safety of personnel
