Problems solved by technology

Although the method of single injection of local anesthetic in the erector spinae plane is simple and easy, it is more difficult to puncture and place a catheter in the fascia and muscle tissue. Unlike blood vessels, epidural space or spinal canal, muscle tissue and The tissue in the fascia is dense, it is difficult to have a natural gap for the catheter to pass through, and it is difficult to place the catheter at the target block, which often leads to block failure or incomplete block effect

Embodiment Construction

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0029] see Figure 1 to Figure 5 A puncture catheterization device for erector spinae plane block under ultrasound guidance is shown, including a puncture needle body 10, a guide component 20, a guide wire 30 and an indwelling catheter 40, which is engraved with a scale.

[0030] The front end of the puncture needle 11 of the puncture needle body 10 is provided with a first developing point 11a, and the first developing point 11a can be imaged under the guidance of ultrasound, so that the user can clearly see the slope direction of the puncture needle body 10 in the muscle tissue.

[0031] The guide component 20 includes a guide rod 21 and a damping guide member 22. The damping guide member 22 is fixed in the middle of the guide rod 21. The damping guide member 22 is preferably a d...

Abstract

The invention discloses a puncture catheterization device for erector spinae plane blockage under ultrasonic guide. The device comprises a puncture needle body and also comprises a guide part, a guide steel wire and an indwelling catheter. The invention also discloses a medicine injection method of the puncture catheterization device for erector spinae plane blockage under ultrasonic guide. The device has the benefits that the indwelling catheter can be accurately placed in the corresponding section of the erector spinae plane and local anaesthesia medicines are injected continuously, so that a good postoperative analgesia effect is achieved, untoward effect is reduced and use of opioid anaesthesia medicines is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a puncture catheterization device for erector spinae plane block under ultrasound guidance and a medicine injection method using the device. Background technique [0002] Ultrasound-guided erector spinae plane block (ESPB) is a newly proposed planar block technique, that is, injecting local anesthetic drugs into the erector spinae plane under ultrasound guidance to spread to the erector spinae plane Up and down, exert an analgesic effect by blocking the spinal nerves passing through this plane. ESPB has the advantages of less morbidity, high operational safety, simple operation, and long block time. It can be used to improve postoperative pain in patients with various thoracic and abdominal operations. Single erector spinae plane injection is convenient and fast, but the analgesic time of single injection of local anesthetic is short. For patients who need long-term postoperative ...
