Embodiment Construction

[0028] Embodiment 1 of a radiofrequency ablation forceps for renal artery sympathetic denervation Figure 1~8 As shown: it includes an ablation head and cannula combination control mechanism. The control mechanism includes a fixed handle 2 and a movable handle 3 hingedly connected to the fixed handle. The hinge axis of the movable handle 3 extends along the left and right directions. The sleeve set includes an outer sleeve 1 whose axis fixedly connected with the fixed handle extends along the front-to-back direction. The sleeve set also includes a pull rod 8 whose rear end in the outer sleeve is hingedly connected to the upper end of the movable handle. The hinge axis of the rear end of the pull rod is arranged along the left-right direction. , so when the movable handle rotates, the movable handle can move back and forth with the pull rod, and the connection between the movable handle and the pull rod belongs to the prior art, and will not be described in detail here. The abl...

Abstract

The invention relates to a kind of radiofrequency ablation forceps for renal artery sympathectomy, being characterized in that the front end of the tie rod is hinged to the upper jaw, the hinge structure includes a hinge shaft integrally arranged with the lower jaw and a hinge hole arranged on the upper jaw, the rear end of the lower jaw is provided with a water inlet and a water return port, thelower jaw is provided with a lower jaw cooling water passage connected between the water inlet port and the water return port, the outer periphery of the articulated shaft is provided with a water inlet ring groove and a backwater ring groove arranged at axial intervals along the articulated shaft, the water inlet ring groove is communicated with the water inlet through a water inlet branch, the backwater ring groove is communicated with the water inlet through a backwater branch, and an upper jaw cooling water passage communicated with the water inlet ring groove and the backwater ring grooveis arranged in the upper jaw. As the temperature of the contact surface is reduced, the problem in the prior art that the radio frequency operation needs to be stop when the temperature of the radiofrequency generator is too high and the operation time is long is solved; meanwhile, the ablation energy is fully released, the ablation effect is ensured, the temperature of the contact surface is reduce and the tissue damage is reduced.

Description

technical field [0001] The invention relates to a radiofrequency ablation forceps for laparoscopic renal artery sympathetic nerve removal in the field of medical instruments. Background technique [0002] Hypertension is a major risk factor for stroke, coronary heart disease, heart failure, vascular disease, and chronic renal failure. Although the pathological and physiological mechanisms of hypertension are complex, the neuroendocrine system is an important mechanism for maintaining blood pressure balance. Excitement is considered to be the basic link in the pathogenesis of hypertension. A large number of animal experiments and clinical studies have also confirmed the influence of sympathetic nerves on blood pressure, and found that the degree of excitement of sympathetic nerves is positively correlated with blood pressure levels of patients. Among them, the renal sympathetic nervous system is the renal sympathetic efferent and afferent nerve closest to the renal artery, w...
