A puncture device based on ultrasound guidance

Abstract

The present invention relates to the field of medical technology, and discloses a puncture device based on ultrasound guidance, including 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, and the holding piece is fixedly installed above the probe. The holding part includes a top base and a long plate. The top base is fixedly connected to the top surface of the probe. There is a hole in the center of the top base and is connected with the cable. The inside of the top base is hollowed out, and the inner wall of the top base is provided with cylindrical protrusions. , there is a chute A on the long board, the inner wall of the chute A is socketed with the cylindrical protrusion, the insert ring B is fixedly connected to the long board, the tooth plate is fixedly connected to the long board, and the gear ring is fixedly connected to the outer wall of the cable. The setting of the holding part can drive the probe to rotate around the cable as the axis through the separation and closing of the fingers after holding, so that during the puncture process, the transition of the puncture needle from out-of-plane guidance to in-plane guidance does not need to change the position of the hand And raise the probe to avoid the problems of unstable holding and awkward sitting posture caused by changing the position of the hand.

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
