Puncture guide and its kit and puncture guide system

Abstract

The invention provides a puncture guide, its set and a puncture guide system, which can realize a puncture channel adaptive to the diameter of a puncture needle in the puncture guide. The puncture guide of the present invention is used to connect with the puncture frame, and the puncture guide includes a depth block and a push plate, wherein: the depth block includes: a connecting structure, used for connecting with the puncture frame; interconnected and form an included angle The first guide wall and the second guide wall; the push plate includes: a needle groove plate; an adaptive component; the first end surface of the needle groove plate and the first guide wall and the second guide wall form a puncture channel , and under the action of the adaptive component, displacement can occur between the first end surface of the needle channel plate and the first guide wall and the second guide wall, so that the puncture channel can be automatically changed according to the specification of the puncture needle , so that it can automatically adapt to puncture needles with different needle diameter specifications. The puncture guide system of the present invention includes a puncture frame and the puncture guide of the present invention.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture guide, its kit and a puncture guide system. Background technique [0002] With the development of medicine and nursing, infusion tools have also developed from simple scalp needles to the choice of intravenous indwelling needles, infusion ports, PICCs and other infusion tools. Doctors need to master the application of various infusion tools. In order to be able to improve the daily work efficiency and nursing level. At present, PICC peripheral central venous catheterization, as a kind of auxiliary infusion tool, is being popularized and applied clinically at an unprecedented speed. Intravenous catheterization is generally performed under ultrasound imaging, with the puncture guide function of the puncture frame, to insert the infusion catheter into the venous vessel. [0003] At present, the puncture of ultrasound image combined with the puncture frame is...

Problems solved by technology

However, the out-of-plane puncture paths are more and more complicated. Generally, the first choice is to insert the needle at the centerline of the probe side, display the target area in the middle of the ultrasonic scanning range, fix the probe position, and insert the puncture needle from the side of the probe through the skin. The distance of the blind zone is too large to see the position of the needle tip, so you need to shake it back and forth while inserting the needle to get a general idea of ​​the depth of the puncture and the distance from the target depth. When the puncture needle returns blood or reaches the target position, it will end, so there are disadvantages It is also obvious: it cannot reach the target position effectively and quickly, and if the needle is not accurate at one time, it needs to be inserted many times

At the same time, since different puncture operations require different sizes of puncture needles, the doctor must select a needle slot matching the diameter of the puncture needle to meet the needs of the operation. The main reason is that the puncture frame is equipped with needle groove plates of various specifications and diameters for doctors to choose during surgery, and the needle groove plates that are not used are scrapped and wasted, which increases the amount of surgical consumables, increases the economic burden of patients, and prolongs the operation time
