Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a drug-assisted injection device and a method of using the same. Background Art

[0002] Minimally invasive interventional therapy is the primary treatment for cardiovascular and cerebrovascular diseases. Guided by fluoroscopic imaging equipment, it utilizes interventional devices to diagnose and treat diseases through physiological cavities. Compared to traditional surgical procedures, it offers significant advantages, including improved efficacy, increased safety, smaller incisions, and shorter postoperative recovery times.

[0003] Vascular interventional procedures primarily include femoral / radial artery puncture, coordinated advancement of a guidewire and angiography catheter, digital subtraction angiography (DSA), coordinated advancement of a therapeutic guidewire and balloon catheter, and stent placement. The coordinated advancement of the guidewire, catheter, and balloon catheter is a time-consuming step in these procedures and requires X-ray image navigation. Currently, vascular interventional procedures are typically performed manually by physicians. During the procedure, DSA emits X-rays, requiring the physician to wear a heavy lead vest. This rapidly degrades the physician's stamina, concentration, and stability, leading to decreased precision and a high risk of life-threatening accidents such as intimal damage and vascular perforation and rupture caused by improper thrust. Furthermore, prolonged wear of the lead vest can damage the physician's spine. Furthermore, the cumulative damage from long-term ionizing radiation exposure significantly increases the physician's risk of leukemia, cancer, and acute cataracts. Therefore, to ensure physician health and surgical quality, research and development of interventional surgical robots is intensifying, and a growing number of robots are now being used in clinical practice.

[0004] When injecting drugs (such as contrast agents, heparin saline or nitroglycerin) during cardiovascular interventional surgery, the doctor needs to inject the drugs into the patient's vascular system through an interventional catheter to perform operations such as vascular imaging. For example, when injecting contrast agents, the existing technology always requires a separate doctor to perform manual operation, which is not convenient for quantitative injection because the doctor needs to rely on his or her own operating experience to perform stable quantitative injection, and the doctor also needs to cooperate tacitly with the surgeon, which places high demands on the doctor's operation and the doctor may also be exposed to radiation damage during the operation.
