Description

Kidney stone rubble stone taking device

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a kidney stone breaking and taking device.

Background

Renal calculus (renal calculi) is caused by abnormal accumulation of crystal substances (such as calcium, oxalic acid, uric acid, cystine and the like) and organic matrixes (such as matrix A, acidic mucopolysaccharide and the like) in the kidney, is a common disease and frequently-occurring disease of the urinary system, male diseases are more than female diseases and frequently occur in young and middle-aged people, the incidence rates of the left and right sides are not obviously different, 90% of the urinary calculus contains calcium, and calcium oxalate calculus is the most common. 40-75% of patients with renal calculus have lumbago of different degrees. Large stones with small mobility, manifested as soreness and distension of the waist, or dull pain during increased physical activity. The colic caused by small stones often suddenly causes severe pain of incised sample of waist and abdomen, and is paroxysmal.

The kidney stone operation is a treatment method which is used for patients who cannot be broken by traditional lithotripsy operations in the kidney or have problems in the kidney of the patient, cannot accept lithotripsy treatment and large kidney stones, has two operation methods of traditional open operation treatment and minimally invasive operation treatment, and needs a scalpel to excise tissues around the kidney stone in the operation process, and the existing scalpel only has an excision function, still needs tools such as tweezers to take out the kidney stone, and is complex in operation and inconvenient to use. When medical staff treat kidney stone patients, under the condition of the current medical level, the method of external stone breaking is mostly adopted, then the patient discharges the internal stone out of the body by himself, but because the external stone breaking directly drops the stone from the kidney, the stone block is possibly bigger, the urethra of the patient is easy to block, and the patient is painful. At present, the main treatment methods mainly include ureteroscope lithotomy and percutaneous nephroscope lithotomy, and the crushed stones are taken out through a lithotomy basket by using ureteroscope lithotripsy and external shock wave lithotripsy respectively. However, the stones taken out each time are limited, the operation difficulty of the stone-taking basket is high, the broken stones are taken out with low efficiency, the pain of the patient is increased by repeated operation, the stones often fall off after being sleeved, and some stones with small sizes can not be grabbed by the stone-taking basket and remain in the renal pelvis to form new stones.
