Multifunctional radio frequency cooling knife

Abstract

The invention provides a multifunctional radio frequency cooling knife which can be used for cutting, coagulating or melting tissues of a patient. The cooling knife comprises a first branch, a second branch, a connecting end part and an operation handle, wherein a cutting head is at least partially limited by the first branch and the second branch to become radio frequency surgical scissors when the first branch is arranged into an angle relative to the second branch; the first cutting head on the first branch is used as a radio frequency melt cutting head when the first branch is overlapped and combined relative to the second branch; and the first branch and the second branch are respectively provided with a cooling device. By combining surgical scissors and radio frequency knife organically, the multifunctional radio frequency cooling knife has multiple functions, can effectively utilize spaces of devices, and has the characteristics of high use frequency and long disposal use time for the multifunctional knives. The convenience for using surgical devices is improved by using a cooling system.

Description

technical field [0001] The present invention relates to the technical field of medical instruments, and more specifically relates to a multifunctional instrument combining radio frequency surgical scissors and intima ablation knife, which is conveniently used for cutting, coagulating, and ablation of patient's tissue, and can be used in various surgical occasions Flexible transformation in use. Background technique [0002] During surgery, it is often necessary to choose different types of knives according to the characteristics of various parts of the human body, the surgical effect and other factors. However, changing the knives many times during the operation not only prolongs the operation time, brings inconvenience to the operating doctor, but also increases the pain of the patient. For example, during the surgical treatment of tumors, it is sometimes necessary to resect a part of the tumor or a functional organ, and sometimes radiofrequency ablation can be used. Using...
