Description

Multifunctional hemostat for postoperative radial artery

Technical Field

The invention relates to the field of hemostasis devices, in particular to a multifunctional hemostat for postoperative radial artery.

Background

The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. The radial artery was about 21.2cm long with an outside diameter of about 0.3cm at the beginning. After the brachial artery is divided, the patient goes downwards and outwards, passes through between the brachioradialis muscle and the circumflex muscle, then is positioned between the flexor carpi radialis and the brachioradialis muscle, and enters the nasopharynx fossa of the pars plana after the lower end of the radius obliquely passes through the tendon deep surface of the extensor hallucis longus and the extensor hallucis brevis to the back of the hand, passes through the gap of the 1 st metacarpal bone and enters the deep part of the palm, and is divided out of the main artery of the thumb, and then is anastomosed with the deep branch of the ulnar artery to form the deep arch of the palm. The radial artery is shallow between the lower end of the radius and the flexor carpi radialis tendon, and is an ideal site for palpating the pulse and performing a puncture. The radial artery has a constant two-vein tracing. Drawing a straight line from 2.5cm below the center of the antecubital fossa to the inner side of the styloid process of the radius, and taking the straight line as the body surface projection of the radial artery.

Coronary intervention is a non-surgical treatment of minimally invasive coronary heart disease. Coronary intervention (TFI) via the femoral artery approach is gradually replaced by radial artery approach intervention (TRI) due to its postoperative complications such as hematoma at the puncture site, vasovagal reflex, venous thrombosis of the lower extremities, arteriovenous fistula, pseudoaneurysm, etc. TRI is a novel interventional therapy method, has small operative wound, few complications and no need of position limitation after operation, is easier to be accepted by doctors and patients, and needs to stop bleeding in time when secondary bleeding is easy to occur after radial artery operation.

The traditional hemostasis method has the defects of poor hemostasis effect and difficulty in adjusting pressure, cannot achieve the purpose of detection when skin bleeding or sweat stain is more, and is easy to cause secondary infection when early warning is lacked.
