Arm fixing device for clinical coronary intervention treatment in cardiology department

Abstract

The arm fixing device comprises a bottom plate, an arc-shaped supporting plate is fixedly connected to the upper side of the bottom plate, the two ends of the upper side of the bottom plate are each fixedly connected with a vertical plate, the upper sides of the two vertical plates jointly support and are fixedly connected with an arc-shaped plate, the arc-shaped plate is slidably connected with a downward pressing device, and the downward pressing device comprises a guide block; the arc-shaped plate is provided with a guide hole, the guide block is slidably connected in the guide hole, the guide block is provided with a through groove, and a plurality of pressing units are slidably connected in the through groove; the pressing unit comprises a guide rod, a pressing block is arranged at the lower end of the guide rod, and an arc-shaped groove is formed in the bottom of the pressing block. By rotating the synchronous wheel, the first pressing block is lifted up to reduce the conveying resistance, and the subsequent pressing block is lifted up along with further penetration of conveyed equipment to reduce the conveying resistance, so that when the arm is clamped, the influence on equipment conveying is reduced to the maximum extent, and the operation speed is increased.

Description

technical field [0001] The invention relates to the technical field of arm fixation devices, in particular to an arm fixation device for clinical coronary interventional therapy in cardiology. Background technique [0002] Vascular interventional surgery is a minimally invasive surgery for the diagnosis and treatment of cardiovascular and cerebrovascular diseases by placing diagnostic or therapeutic items into the vascular lesions through blood vessels. It is an advanced technology for the diagnosis and treatment of cardiovascular and cerebrovascular stenotic lesions, especially coronary atherosclerosis and other diseases. [0003] Patent Bulletin No. CN215537388U discloses an arm fixing device for coronary interventional therapy. After the device is fixed on the arm, it will cause arterial compression, and the delivery of orthopedic stents may not be smooth, which affects the process of surgery. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to...
