[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 e...

Example Embodiment

[0020] In order to make it easy to understand the technical means, creative features, goals and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific embodiments.
[0021] Such as Figure 1-4 As shown, a minimally invasive scalpel for urological tumors according to the present invention includes a scalpel body 1. A support ring 2 is fixedly connected to the top of the scalpel body 1 and at a position away from the tip of the scalpel. The inner diameter of the support ring 2 The size is 0.6-0.8cm. The support ring 2 is made of medical grade materials. A part of the bottom of the support ring 2 is located inside the scalpel body 1. When working, due to the thin thickness of the existing scalpel body 1, the intern holds the operation During training of the scalpel body 1, due to unskilled operation or high tension, the scalpel body 1 will fall. If the scalpel body 1 falls on the ground, the tip of the scalpel body 1 is likely to be blunt. It will cause serious injury to personnel and affect the safety of use. Therefore, the present invention mainly solves how to prevent the scalpel body 1 from falling during use, and ensure the service life of the scalpel body 1 and the safety of personnel. Specific solutions And the working process is as follows: by fixing the support ring 2 on the top of the scalpel body 1 and away from the tip of the knife, the intern can place the scalpel body 1 with his thumb and middle finger. Pinch the scalpel body 1 on both sides of the scalpel body 1, and then insert the index finger into the support ring 2 on the top of the scalpel body 1. If the operator does not pinch the scalpel body because of unskilled operation or high tension When the situation of 1 occurs, because the index finger is inserted into the support ring 2, the index finger prevents the support ring 2 from falling, thereby preventing the scalpel body 1 from falling and causing the tip of the scalpel body 1 to become blunt or cause personnel The occurrence of injury increases the service life of the scalpel body 1 and ensures the safety of personnel.
[0022] The inner top of the support ring 2 is fixedly connected with a hollow capsule 3, the bottom of the hollow capsule 3 is glued with a rotating plate 4, the end of the rotating plate 4 near the tip of the knife is fixedly connected with a rotating shaft 5, and both ends of the rotating shaft 5 are located in the support ring 2. In terms of wall thickness, a curved plate 6 is fixedly connected to the bottom of the rotating plate 4 near the tip of the knife. The bottom end of the curved plate 6 is near the tip of the knife. Two hoses 7 are connected to the hollow bag 3, and the hose 7 penetrates the support ring 2 and is embedded. On the surface of the scalpel body 1, and the end of the hose 7 is located at the tip of the knife; during use, the blood in the tumor tissue at the surgical site will gather at the tip of the scalpel body 1, interfering with the resection during the operation. During the operation after the index finger is inserted into the support ring 2, when the blood needs to be removed, the doctor can push the curved plate 6 at the support ring 2 with the index finger. The curved plate 6 drives the rotating plate 4, and the rotating plate 4 goes around When the rotating shaft 5 rotates, it can drive the hollow capsule 3 to expand. When the index finger loosens the curved plate 6, the hollow capsule 3 becomes smaller from the stretched state under the recovery action of its own elastic force. The hollow capsule 3 can be The gas inside is forced out through the hose 7 to blow the blood at the surgical site to prevent the blood from approaching the tip of the knife, reduce the accumulation of blood at the tip of the knife, and improve the quality of the operation.
[0023] The hose 7 is internally connected with multiple groups of blocking units, each group of blocking units includes two baffles 8, one end of the two baffles 8 is bonded to the inner wall of the hose 7, and the other end of the two baffles 8 Since the scalpel body 1 is thinner, the hose 7 embedded in the surface of the scalpel body 1 is thin, and the gas is blown out when the gas is blown out from the thin hose 7 Therefore, multiple sets of blocking units are arranged inside the hose 7, and each set of blocking units includes two baffles 8, so that when the hollow bag 3 is restored, the gas inside the hollow bag 3 is blown out of the hose 7 When passing through each set of blocking units, the gas separates the two baffles 8 in contact. After the gas passes through multiple sets of blocking units, the strength of the gas can be significantly reduced, and finally the strength of the gas blown from the hose 7 is weakened, preventing Stronger gas affects the skin tissue around the operation.
[0024] The hollow bladder 3 is connected with a hollow curved tube 9 on the side close to the blade tip, and a vertical rod 10 is inserted into the vertical section of the hollow curved tube 9, and the vertical rod 10 matches the hollow curved tube 9, and the vertical rod 10 The bottom end can move along the vertical section of the hollow curved tube 9 to a position close to the top of the vertical section; when the stretched hollow capsule 3 recovers, part of the gas is ejected from the hose 7 and part of the gas enters the hollow curved tube In 9, the vertical rod 10 is pushed up to disperse the amount of gas that enters the hose 7, so that the amount of gas entering the hose 7 at the beginning is reduced, thereby reducing the strength of the gas when the hose 7 is sprayed. After the straight rod 10 rises to the maximum value, the gas in the hollow sac 3 can completely enter the hose 7, which can make the tumor tissue have a process of adapting to the blown gas, and then maintain a greater strength to make the blood on the tumor tissue free from the knife. The tip is scattered, reducing the sensitivity of the skin tissue.
[0025] The surface of the vertical rod 10 is coated with lacquer, and the color of the lacquer gradually changes from the bottom to the top. By applying different colors of lacquer on the surface of the vertical rod 10 from the bottom to the top, it can be observed from the hollow curved tube 9 The color that is removed from the inside. When there are many types of colors that are removed from the hollow elbow tube 9, it indicates that the intensity of the gas ejected from the hose 7 at this time is relatively large. It is necessary to observe the change of blood content at the knife tip in time, and whether it is necessary to adjust the knife tip The distance from the tumor tissue ensures that the impact on other parts during the operation is minimized.
[0026] A plurality of rubber rods 11 are fixedly connected to the support ring 2 at a position away from the tool tip. The diameter of the free end of the rubber rod 11 is smaller than the diameter of the fixed end of the rubber rod 11, and the rubber rod 11 is bent in the direction of the tool tip; 11 When the index finger is inserted into the support ring 2, there is a greater friction with the index finger. After the thumb and middle finger loosen the scalpel body 1, and the index finger is in an inclined state, the friction action of the rubber rod 11 reduces the support ring 2The chance of slipping from the index finger further reduces the risk of the scalpel body 1 falling.
[0027] During work, due to the thin thickness of the existing scalpel body 1, when the trainee holds the scalpel body 1 for training, the scalpel body 1 will fall due to unskilled operation or high tension. When the knife body 1 falls on the ground, it is easy to cause the tip of the scalpel body 1 to be blunt, which may cause personal injury and affect the safety of use. Therefore, the present invention mainly solves how to prevent the scalpel body 1 from falling during use. To ensure the service life of the scalpel body 1 and the safety of personnel, the specific solutions and work process are as follows: by fixing the support ring 2 on the top of the scalpel body 1 and away from the tip of the knife, the intern In the process of holding the scalpel body 1, you can place the thumb and middle finger on both sides of the scalpel body 1 to pinch the scalpel body 1, and then insert the index finger into the support ring 2 on the top of the scalpel body 1. If a person does not pinch the scalpel body 1 due to unskilled operation or high tension, because the index finger is inserted into the support ring 2, the index finger prevents the support ring 2 from falling, thereby preventing the operation The falling of the scalpel body 1 may cause the tip of the scalpel body 1 to become dull or cause personal injury, which improves the service life of the scalpel body 1 and ensures the safety of personnel.
