Ultrasound-guided precise puncture guide ruler

Abstract

The invention belongs to the technical field of medical operation tools, and particularly relates to an ultrasonic guidance precise puncture guiding ruler. The puncture guiding ruler comprises a base,a fulcrum rod, a puncture guiding tube and a sliding block. The base comprises two symmetric metal sheets, one ends of the two metal sheets are connected and fixed together, the other ends of the twometal sheets freely stretch, and a gap is formed between the two metal sheets. A first groove hole formed in the width direction of the sliding block and a second groove hole formed in the length direction of the sliding block are formed in the sliding block. A square sliding block inner core is inserted into the second groove hole, the sliding block inner core moves in the hole length directionof the second groove hole and is braked and fixed through a second brake button, a through groove is formed in the end, close to the fulcrum rod, of the sliding block inner core, and the puncture guiding tube penetrates through the through groove hole and freely slides. The ultrasonic guidance precise puncture guiding ruler is in a plane external puncture guiding manner, and the precision that anultrasonic guidance puncture needle reaches the target kidney calix direction and depth is improved.

Description

technical field [0001] The invention belongs to the technical field of medical operation appliances, and in particular relates to an ultrasound-guided precise puncture guide ruler. Background technique [0002] Urolithiasis is one of the most common diseases in urology, ranking first among inpatients in urology. In Western European and American countries, the annual new incidence of urinary stones is 100-400 / 100,000 people, and 5%-10% of people will have urinary stones at least once in their lifetime. According to epidemiological data, my country has become one of the three high-incidence areas of stones in the world. The incidence of urinary stones is about 1%-5%, while in the south of my country it can be as high as 5%-10%. There is also an increasing trend. Upper urinary tract stones are more common in urinary tract stones, while upper urinary tract stones occur insidiously and generally have no obvious clinical symptoms. The most common symptoms are waist pain and hemat...

Problems solved by technology

The freehand puncture technique mainly includes the in-plane puncture technique and the out-of-plane puncture technique. Both the in-plane puncture technique and the out-of-plane puncture technique require a lot of practice, and the learning curve is long, which is a difficult bottleneck for novices. , and it is difficult to achieve precise puncture

However, the initial design of the current ultrasonic puncture guide is mainly aimed at guiding the puncture in the ultrasonic plane. It wastes operation time; the puncture line is relatively fixed, and the puncture route cannot be freely adjusted according to the intraoperative situation; in addition, the GPS ultrasound-guided puncture system is beneficial to improve the accuracy of puncture, but its wide application is limited due to the high cost of equipment
