Radiofrequency ablation probe without scales for cavity organs

Abstract

The invention discloses a radiofrequency ablation probe without scales for cavity organs. The probe comprises a tube body, an energy applying device and a marking device, the energy applying device islocated at the front end of the tube body, and the marking device is installed on the tube body; the marking device further comprises a locating block, a marking block and a metering part connected between the locating block and the marking block, the marking block further comprises a soft elastic body and a hard clamping plate, and a second through hole for the tube body to penetrate through isformed in the soft elastic body; the hard clamping plate is installed in the second through hole through a rotary piece, and when the front end of the hard clamping plate makes extrusion contact withthe circumferential wall of the tube body, a gap is reserved between the back end of the hard clamping plate and the circumferential wall of the tube body. According to the radiofrequency ablation probe, it is avoided that printed marks enter the human body, so that the adverse influence on the human body is caused, the use safety of the radiofrequency ablation probe without the scales for the cavity organs is improved, the influence of the marking device on the treatment process can also be reduced, a worker conveniently controls the position of the marking block, and the moving precision ofthe marking block is effectively improved.

Description

technical field [0001] The invention relates to a radio frequency ablation probe for cavity organs without scale, which belongs to the field of medical equipment. Background technique [0002] Radiofrequency ablation technology is a minimally invasive technique that has been widely used in heart, cancer tumors, skin and other lesions in recent years. The entire treatment system generally includes two parts: a radiofrequency generator and a radiofrequency ablation probe. [0003] Among them, when the treatment system uses a radio frequency generator to generate and control radio frequency energy, and when the radio frequency energy is applied to human tissue through the radio frequency ablation probe for treatment, the end of the radio frequency probe is generally inserted into the distal end of the organ in the cavity, and the organ is segmented For ablation treatment, after one section of treatment is completed, a certain length is pulled out to start the next section of tr...

Problems solved by technology

[0004] Therefore, in the prior art, an equidistant scale covering the tube body is printed on the radio frequency ablation probe. However, due to the long length of the tube body, it is difficult for transfer printing machines on the market to meet the printing requirements. Extended transfer printing machine, resulting in increased production costs, and, when printing with ink, the residual ink and auxiliary reagents on the tube body will enter the human organs, which is likely to cause the risk of injury
