Problems solved by technology

[0003] However, the traditional percutaneous nephroscope still has defects. For example, when the expansion is performed after the puncture, the traditional expansion sheath cannot observe the position of the expansion sheath, which may easily cause medical accidents such as excessive puncture and renal hemorrhage.

Abstract

The invention relates to a percutaneous nephroscopic expansion sheath, which comprises a tear sheath and an expansion tube arranged in the tear sheath. The expansion tube is cylindrical, with a conical front end, and the top of the cone is a circular plane. A fiber optic channel and a guide wire channel are provided, and the fiber channel and the guide wire channel are arranged parallel to the expansion tube, and the fiber channel passes through the circular plane, and the guide wire channel passes through the outer surface of the cone, and the fiber channel is concentric with the circular plane. The beneficial effect of the present invention is that the visual image system can be used to effectively locate the puncture expansion when the expansion puncture is performed by using the visible expansion sheath, so as to prevent medical accidents such as renal hemorrhage caused by too deep puncture in conventional operations.

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...
