Horizontal position fixing device for renal artery radiofrequency ablation

Abstract

The invention discloses a horizontal position fixing device for renal artery radiofrequency ablation. The horizontal position fixing device comprises a traction module, a lower limb positioning module and a body positioning module, wherein the traction module is used for pulling loose abdominal skin of an obese hypertension patient; the body positioning module is used for fixing shoulders on two sides of the patient; the lower limb positioning module is used for knee-bending abduction fixation of the lower limb of the patient at a puncture side; the traction module comprises a rocker arm, one end of the rocker arm is hinged to a first shaft rod, and the other end of the rocker arm is connected with a supporting plate through a screw and a tension device; the supporting plate is further connected with a second shaft rod; the second shaft rod is connected with the first shaft rod; an abdomen positioning device is further installed in the middle of the second shaft rod; the abdomen positioning device is used for positioning the abdomen of the patient; an adjusting block is installed on the upper portion of the rocker arm; a traction arm is installed in the adjusting block; a ball head is arranged at the other end of the traction arm and sleeved with a ball seat; the ball seat is locked on the ball head through a locking bolt; and a suction cup is installed at the end, away from the ball head, of the ball seat and used for sucking the skin of the abdomen of the patient.

Description

technical field [0001] The invention relates to the medical field, in particular to a supine fixation device for renal artery radiofrequency ablation. Background technique [0002] Hypertension is a common cardiovascular disease and an important risk factor for other cardiovascular diseases. Refractory hypertension refers to the application of 3 or more antihypertensive drugs with the largest dose after improving diet and lifestyle. It is still not up to the standard. Drug treatment is difficult to make the blood pressure of patients with refractory hypertension reach the target. The incidence of target organ damage in patients is significantly increased. The enhancement of renal sympathetic nerve activity is an important mechanism for the development of hypertension. Therefore, radiofrequency ablation of the renal artery is used Surgical renal denervation is an important treatment strategy for refractory hypertension. Surgical sympathectomy greatly improves the survival rat...
