Calculus gripping device for urinary surgery

Abstract

The invention provides a calculus gripping device for urinary surgery, and effectively solves the problems that calculus often slides off and is left in the body of a patient due to insufficient friction force when the calculus is clamped by tweezers or operating forceps, and the calculus removing efficiency is reduced. The problems that a large amount of cleaning liquid needs to be injected into the bladder of a patient during flushing, the cleaning effect is poor, large-particle broken stones cannot be discharged along with the cleaning liquid, and the cleaning effect is not thorough enough are solved. A conveying screw rod is rotatably mounted in the inserting pipe, a conveying plate slidably mounted on the inserting pipe is mounted on the conveying screw rod in a threaded mode, right pushing rods are rotatably mounted at the front end and the rear end of the right side of the conveying plate correspondingly, and left pushing rods are rotatably mounted at the front end and the rear end of the front side of the conveying plate correspondingly; and through cooperation of a power rod, a driving rack, a driving gear and a clamping shell, large-particle stones can be treated more conveniently, and the situation that the large-particle stones are difficult to treat, and pain is brought to a patient is avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a calculus grasping device for urology. Background technique [0002] Bladder stones are stones that form in the bladder, and are divided into primary bladder stones and secondary bladder stones. The former refers to the formation of stones in the bladder, mostly caused by malnutrition, mostly in children. With the continuous development of my country's economy, children's bladder stones are now showing a downward trend. The latter refers to bladder stones originating from upper urinary tract or secondary to lower urinary tract obstruction, infection, bladder foreign body or neurogenic bladder. In economically developed areas, bladder stones mainly occur in elderly men, and most of them suffer from benign prostatic hyperplasia or urethral stricture. In addition to malnutrition factors, lower urinary tract obstruction, infection, bladder foreign body, and metabolic diseases can...

Problems solved by technology

[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a stone grabbing device for urology, which effectively solves the problem that the stones often fall off and remain in the In the patient's body, the problem of reducing the efficiency of stone extraction and the structure of the existing flushing device is relatively simple. During flushing, more cleaning fluid needs to be poured into the patient's bladder, and the cleaning effect is poor, and larger particles of gravel cannot be discharged with the cleaning fluid. , the cleaning effect is not thorough enough
