Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] see Figure 1-Figure 3 , a disposable dilatation sheath for percutaneous nephroscopic visualization, including a tear sheath 100 and a dilation tube 200 arranged in the tear sheath 100, the dilation tube 200 is cylindrical, the front end is a cone, and the top of the cone is a circular plane 230 , an optical fiber channel 210 and a guide wire channel 220 are disposed in the expansion tube 200 . Wherein the optical fiber channel 210 can pass through the optical fiber and inject water, and the guide wire channel 220 can pass through the guide wire. The fiber channel 210 and the guide wire channel 220 are arranged parallel to the dilation tube 200 , and both the fiber channel 210 and the guide wire channel 220 pass through the circular plan...

Abstract

The invention relates to a disposable and visible expansion shealth of a percutaneous nephroscope. The expansion shealth includes a tearing sheath and an expansion pipe arranged in the tearing sheath, the expansion pipe is cylindrical, the front end of the expansion pipe is in a cone shape, the top of the cone is a circular plane, the expansion pipe is internally provided with an optical fiber channel and a wire guide channel, the optical fiber channel and the wire guide channel are parallel to the expansion pipe, and both the optical fiber channel and the wire guide channel pass through the circular plane. The disposable and visible expansion shealth has the advantages that the visible expansion shealth can use a visible imaging system for effectively conducting puncture expansion positioning when expansion puncture is conducted, and medical accidents, such as renal hemorrhage, caused by deep puncture of a conventional surgery are avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a percutaneous nephroscope. Background technique [0002] Surgical treatment methods for kidney stones include: open lithotomy, extracorporeal lithotripsy, and percutaneous nephrolithotomy. The traditional method of "removing stones with a knife" requires a large incision of about 20 cm in the waist, incision of the muscles in the waist, separation of the kidneys, and a small incision in the renal pelvis or renal parenchyma to remove the stones. This method causes more damage, more bleeding, more pain, and slower recovery. Usually you need to stay in the hospital for about 7 days after the operation. Because the surgical incision is large, not only the skin is not beautiful, but also the physical strength of the patient is greatly affected after the operation. Compared with open surgery, percutaneous nephrolithotomy has the advantages of less damage, less pain, complete stone removal, and f...
