Ultrasonic guidance-based puncture device

Abstract

The invention relates to the technical field of medical treatment, and discloses an ultrasonic guidance-based puncture device. The ultrasonic guidance-based puncture device comprises a probe, a cable,a holding piece and a contact piece; the cable is located at the center of the top end of the probe; the holding piece is fixedly installed over the probe; the holding piece includes a top seat and along plate; the top seat is fixedly connected with the top face of the probe; a hole is formed in the center of the top seat and is connected with the cable in a sleeving manner; the interior of thetop seat is in a hollow state; the inner wall of the top seat is provided with a cylindrical protrusion; a sliding groove A is formed in the long plate; the inner wall of the sliding groove A is connected with the cylindrical protrusion in a sleeving manner; the long plate is fixedly connected with an insert ring B; the long plate is fixedly connected with a toothed plate; and the outer wall of the cable is fixedly connected with a toothed ring. By installing the holding piece, through separation and closing of fingers after holding, the probe can be driven to rotate with the cable as the axis, and thus, in the puncture process, the transition from out-of-plane guidance to in-plane guidance of a puncture needle does not require changing a hand position and lifting up the probe, thereby avoiding the problems of unstable holding and an awkward sitting posture caused by changing the hand position.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a puncture device based on ultrasound guidance. Background technique [0002] Ultrasound-guided puncture therapy is a technology that uses ultrasound emitted by equipment to display the patient's subcutaneous muscles and blood vessels and other organs, so as to guide the puncture of the puncture needle for treatment. Ultrasound-guided puncture needs to emit ultrasound through the probe corresponding to the patient's part, and then puncture The needle is punctured under the probe. [0003] The existing patent No. CN109567906B proposes a puncture needle and an ultrasonic puncture device, which has the advantage of reducing or even eliminating the mutual interference of various data / signals transmitted in the puncture needle, but when it is used, when the user needs to guide the When changing to in-plane guidance, the angle of the probe needs to be changed by 90 degrees. At this t...

[0003] The existing patent No. CN109567906B proposes a puncture needle and an ultrasonic puncture device, which has the advantage of reducing or even eliminating the mutual interference of various data / signals transmitted in the puncture needle, but when it is used, when the user needs to guide the When changing to in-plane guidance, the angle of the probe needs to be changed by 90 degrees. At this time, the puncture needle has been inserted into the patient’s skin. When the user changes the position of the probe, it can only be operated with one hand. When the finger changes position on the outer wall of the probe When holding the finger, it is easy to cause the problem of falling due to unstable holding, and there is a risk of the probe falling and causing damage. If the holding position of the finger is not changed, it is necessary to change the palm angle or change the user's sitting posture, etc., which will affect the holding of the probe or puncture. needle stability
