Flexible percutaneous renal puncturing support guided by color ultrasound

Abstract

The invention relates to a flexible percutaneous renal puncturing support guided by color ultrasound. The flexible percutaneous renal puncturing support has different beneficial effects from previouscolor ultrasound positioning puncturing supports by improving the color ultrasound positioning puncturing support. On the one hand, a puncturing needle sleeve ensures that a puncturing needle is always on a plane displayed by a puncturing probe when the puncturing needle is inserted, targeted renal calices can be accurately punctured in the real-time monitoring state, and the puncturing difficultyof percutaneous renal operations is greatly reduced; on the other hand, the puncturing angle can be flexibly adjusted through a chain puncturing support, the needle-inserting angle is adjusted at will in the plane displayed by the puncturing probe, and the free adjustment of the needle-inserting angle ensures the distance of a kidney tract to be as short as possible, so as to reduce the difficulty of subsequent operations. Percutaneous renal surgery is a difficult operation for urologists in the treatment of urolithiasis, due to worse puncture position, the quality of the whole operation is affected, during the operation, important organs or great vessels can be injured, and serious complications are caused; and according to the flexible percutaneous renal puncturing support, the operation difficulty can be obviously reduced, operation time is shortened, the operation method can be popularized in more hospitals, and benefits between operators and patients are achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a color ultrasound positioning puncture frame. Background technique [0002] In the process of percutaneous renal puncture in urology, the traditional method is that the operator holds the color ultrasound probe in one hand and the puncture needle in the other hand for freehand puncture. This situation may easily cause the puncture needle to deviate from the display plane of the probe, making it impossible to monitor the position of the puncture needle And puncture depth, resulting in puncture failure or even injury to important organs or large blood vessels, causing serious complications. Most of the existing color ultrasound positioning puncture frames are fixed, and the angle of the color ultrasound positioning puncture frame cannot be adjusted. The puncture of the operator brings great inconvenience, which reduces the practicability of the color ultrasound positioning puncture frame. Co...
