Description

Ultrasonic probe protective sleeve with intraoperative positioning function

Technical Field

The utility model relates to the field of medical instruments, in particular to an ultrasonic probe protective sleeve with an intraoperative positioning function.

Background

Interventional ultrasound is guided in real time by means of ultrasound images, accurately guides puncture needles, catheters and the like to lesions or targets, and further diagnoses and treatments by minimally invasive techniques to avoid many traditional surgical operations. According to the relationship between the needle inserting path of the puncture needle and the ultrasonic beam, the method is divided into an in-plane method and an out-of-plane method. The needle insertion path perpendicular to the ultrasound beam is called out-of-plane method, and the puncture needle is displayed as a high echo point on the screen. The needle is inserted in an out-of-plane method, and the distance from the puncture needle to the target is shorter than in-plane method. Thus, the damage to the tissue is relatively small. Is particularly suitable for biopsy in craniotomy, and has the advantages of small operative field, small injury, simple operation and the like due to craniocerebral operation. The needle is inserted out of plane, and the other advantage is that the target area is relatively clearly adjacent to the surrounding tissue anatomy, so the needle is also suitable for sucking cell biopsy thyroid nodules by a fine needle, and the risk of damaging peripheral nerves and blood vessels can be reduced. In addition, out-of-plane needle insertion is also the preferred needle insertion method in ultrasound-guided arteriovenous catheterization. However, the out-of-plane method needle insertion has an obvious disadvantage that the needle insertion position of the puncture needle cannot be effectively displayed because the puncture needle and the needle point cannot be displayed, and once the needle insertion position deviates greatly from the skin projection point of the target tissue or blood vessel, the success rate of puncture or tube placement is reduced, and the needle withdrawal and needle insertion are required to be repeatedly carried out for many times to determine the needle insertion position. Therefore, when the out-of-plane method is adopted to carry out the tissue puncture biopsy or the arteriovenous catheterization under the ultrasonic guidance, how to effectively determine the needle inserting position is very important.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides an ultrasound probe protection cover with a novel structure and a convenient use, which has an intraoperative positioning function, and can accurately indicate a needle insertion position of a puncture needle corresponding to a target region, thereby improving a success rate of puncture or catheterization.
