Abstract

The invention discloses a low-temperature plasma scalpel with an integrated three-dimensional electrode. The low-temperature plasma scalpel comprises a scalpel head handle, a steel tube and a ceramic head, wherein a through hole is formed in the scalpel head handle; the steel tube is connected with the front end of the through hole of the scalpel head handle; the ceramic head is connected with the steel tube; at least one perforation is formed in a side part of the ceramic head; the integrated three-dimensional electrode used for cutting, ablating and coagulating tissues is inserted into the perforation; and an absorption cavity used for absorbing the cut tissues is formed in a middle part of the ceramic head. According to the low-temperature plasma scalpel provided by the invention, the plugging problem of the plasma scalpel head in the actual application process can be effectively solved, offset does not exist in assembly of the ceramic head and the steel tube, and normal saline can be perfectly guided onto the integrated three-dimensional electrode on the ceramic head. Moreover, the low-temperature plasma scalpel disclosed by the invention is simple in insulating treatment, easy to assemble and high in quality and stability.

Description

technical field [0001] The invention relates to the field of medical plasma surgical instruments, in particular to a low-temperature plasma surgical knife with integrated three-dimensional electrodes. Background technique [0002] With the development of science and technology, the scalpel is becoming more and more high-tech, and the plasma scalpel is more and more widely used in various operations. [0003] However, with the wide application of this technology, more and more problems have been exposed in the clinical application of plasma scalpels. The existing plasma scalpels mainly have the following defects: [0004] 1) The existing plasma scalpel can only discharge waste tissue and liquid during the operation through a narrow suction channel. However, due to the limitation of the size of the knife head, the problem of blockage of the knife head often occurs during the operation. It brings a lot of inconvenience to the continuity of the operation, and greatly reduces th...
