Ultrasonic out-of-plane puncture guide stent

Abstract

The invention discloses an ultrasonic out-of-plane puncture guide stent, and relates to the technical field of medical instruments. The ultrasonic out-of-plane puncture guide stent comprises a fixing seat and a puncture frame. Openings are formed in the upper end and the lower end of the fixing seat, through grooves are formed, the outer side of an ultrasonic probe is sleeved with the through grooves, and the through grooves are used for fixing the ultrasonic probe; the puncture frame is vertically arranged in the center of the side wall of the fixing seat and comprises a puncture frame body, scale marks are arranged on the side wall of the puncture frame body, a sliding groove is formed in the top of the puncture frame body, and a guide needle sliding block is arranged in the sliding groove in a sliding mode; and the upper surface of the guide needle sliding block is provided with at least two guide needle channels which penetrate through the lower bottom face of the guide needle sliding block and are used for guiding and fixing puncture needles, and needle outlets of the guide needle channels face the central axis of the ultrasonic probe. According to the guide stent, operation is convenient, the puncture direction, the puncture angle and the puncture depth are convenient to control, the difficulty and the workload of a doctor for puncture are greatly reduced by setting a buzzer early warning function, the accuracy and the efficiency of puncture are improved, and the pain of a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ultrasonic out-of-plane puncture guiding bracket. Background technique [0002] Ultrasound-guided puncture is a technology developed on the basis of ultrasound imaging to meet the needs of clinical diagnosis and treatment. Through the puncture needle, it is very convenient to extract the diseased tissue in the patient's body or to a certain target site in the patient's body (such as a tumor). , nerves, blood vessels, etc.) in ultrasound-guided puncture, according to the relative position of the puncture needle and the ultrasound probe, can be divided into in-plane puncture techniques (the puncture needle is parallel to the long axis of the ultrasound probe) and out-of-plane puncture techniques (puncture The needle is perpendicular to the long axis of the ultrasound probe). [0003] When the in-plane puncture technique is used, the needle path can be fully displayed on...

AI Technical Summary

Problems solved by technology

However, while having many advantages, out-of-plane puncture also has some limitations, such as the inability to effectively display the position of the puncture needle, the understanding of the puncture path is not intuitive, it is difficult to understand, and it is difficult to distinguish whether the needle tip of the puncture needle just reaches the developing surface The corresponding position has passed through the corresponding position of the corresponding developing surface, making it inconvenient to control the puncture depth, requiring the operator to constantly adjust the angle of the probe, which makes the operation of out-of-plane puncture difficult, which is very difficult for beginners. Difficult to learn and operate skillfully, clinical application is also subject to certain technical limitations
