A water-cooled electromagnetic hemostatic needle

Abstract

The invention discloses a water-cooled electromagnetic bleeding-stopping needle, belonging to the field of medical devices. The water-cooled electromagnetic bleeding-stopping needle comprises an outer conductor (1), an inner conductor (2), a medium layer (3) and a water guide pipe (5), wherein the outer conductor (1) is a hollow cylinder, the inner conductor (2) is arranged in the outer conductor (1), the space between the inner conductor (2) and the outer conductor (1) is filled with the medium layer (3), the inner conductor (2) is a hollow cylinder, the water guide pipe (5) is arranged in the inner conductor (2), and placed along the axial direction of the inner conductor (2), and a gap is reserved between the water guide pipe (5) and the inner conductor (2). The water-cooled electromagnetic bleeding-stopping needle is ingenious in structure, while the problems existing in the water-cooling circulating systems of the traditional electromagnetic bleeding-stopping needles are solved, the size of the water-cooled electromagnetic bleeding-stopping needle provided by the invention is effectively reduced, further, by adjusting the position of a metal sleeve, the number of effective gaps is randomly regulated from one to more according to the electromagnetic shielding principle, so that the actuating range and effect shape of electromagnetic waves are changed.

Description

technical field [0001] The invention relates to a medical device, in particular to a water-cooled electromagnetic hemostatic needle. Background technique [0002] For liver neoplastic diseases, the best treatment option is recognized surgical resection. However, surgical resection of liver tumors is not suitable for every patient. If the primary or metastatic tumor of the liver metastasizes intrahepatically or extrahepatically, surgical resection at this time has no obvious significance; in addition, most patients with liver tumors in my country are often accompanied by severe liver cirrhosis due to long-term damage of hepatitis virus However, the reduced liver reserve function cannot tolerate surgical resection; in the above cases, only ablation of local tumor lesions to kill tumor cells has been widely approved. Before the operation, the surgeon will formulate a treatment plan according to the specific condition of the patient, and plan to perform surgical resection or lo...

Problems solved by technology

[0006] The present invention aims to provide a water-cooled electromagnetic hemostatic needle, which has a delicate structure. While solving the problem of the water cooling circulation system of the electromagnetic hemostatic needle, it can effectively reduce the size of the electromagnetic hemostatic needle, and can also adjust the position of the metal sleeve so that Through the principle of electromagnetic shielding, the number of effective gaps can be freely adjusted to one or more, thereby changing the range and effect shape of electromagnetic waves
