Ultrasonic and acoustic guided automatic assisted-type epidural puncture assistance system

Abstract

The invention discloses an ultrasonic and acoustic guided automatic assisted-type epidural puncture assistance system, which is composed of two parts, namely an ultrasonic and acoustic guided automatic assisted-type epidural puncture apparatus and an assisted puncture and control handle, wherein the ultrasonic and acoustic guided automatic assisted-type epidural puncture apparatus is composed of an ultrasonic probe interface, an injection pump component, a pressure sensor, a pressure taking device, a box compartment, a box compartment snap, a loudspeaker, a connecting pipeline, a touch display screen and a circuit module; the assisted puncture and control handle is composed of a disposable positioning mark sliding displacing and supporting elastic sheet, a puncture needle component, a driving shaft linear stepping motor driver, a puncture needle displacement sensor, a rotary switch, a lever type switch, a dual-axis tilt sensor, a rechargeable battery pack, an ultrasonic probe and a connecting cable as well as a connecting pipeline, an injection pump, a pressure sensor and a puncture needle component; and the ultrasonic probe is connected to the dual-axis tilt sensor and the ultrasonic probe interface by virtue of cable lines. With the application of the assistance system provided by the invention, puncture accuracy can be enhanced and complications caused by failure can be reduced.

Description

Technical field [0001] The present invention relates to a medical device, especially an anesthesia occasion that is used in surgery, obstetrics and gynecology operations and other postoperative pain control (such as postoperative analgesia of lower limbs, perineum, pelvis, abdomen and thoracic surgery). The doctor locates the puncture needle position as soon as possible, improves the doctor’s work efficiency, reduces the patient’s pain, and reduces the possibility of complications caused by puncture failure. The ultrasound and sound wave guided automatic assisted epidural puncture assist system. Background technique [0002] Epidural anesthesia is widely used in clinical practice. It is often used for intraoperative and postoperative analgesia of limbs, abdomen or thoracic surgery. It can also be used for other analgesia such as ischemic pain in the legs and analgesia in hospice care. , Emergency analgesia for trauma patients, as well as application in the painless delivery of gy...

Problems solved by technology

[0006] In order to overcome the fact that the existing epidural puncture needle is greatly affected by human factors, the operation is all based on the operator's experience. If the operator is not experienced enough, it is easy to cause the puncture needle to fail, and the puncture needle punctures the patient's epidural cavity, thus leading to serious postoperative complications, bringing physical pain and economically redundant disadvantages to the patient, the present invention provides a method for surgery, obstetrics and gynecology operations and other postoperative pain control (such as Anesthesia for lower extremity, perineum, pelvis, abdominal and thoracic surgery) use ultrasonic probe for ultrasonic scanning, measure the tissue structure of the puncture site and plan the puncture path, depth and angle, and pre-determine the entry point of the puncture needle Wave guidance, by converting the resistance information between the tissues in the traditional epidural puncture into auditory information feedback to prompt the tissue where the puncture needle is located, combined with the tactile information on the hand of the anesthetist, the anesthetist can understand in real time the puncture process during the puncture The position of the needle can automatically and accurately control the walking process of the puncture needle, and the OR gate control circuit is composed of the preset puncture depth parameters and the real-time measured pressure sound wave signal to ensure that excessive puncture is prevented, thereby reducing dura mater puncture or other serious problems Complications, after the puncture needle enters the epidural space, the anesthesiologist can help the anesthesiologist confirm the position of the front end of the epidural catheter after the puncture needle enters the epidural space. If the position of the front end of the catheter is not suitable, the position can be adjusted in time. The resistance signal measured during the entire operation can also be stored in the memory carrier, and printed out with a printing device for review and analysis as needed Ultrasound and sound wave guided automatic assisting epidural puncture assistance system
