Description

A kind of low-temperature plasma therapy system

Technical field

The present invention relates to technical field of medical instruments, relate in particular to a kind of low-temperature plasma therapy system.

Background technology

The understanding systematicly of mankind's plasma starts from the gas discharge research of the 1830's, in 20 beginnings of the century, set up plasma concept, and what a large amount of concrete interactional charged particles, consist of has a system that macroscopical space-time is blunt.Plasma, according to the relative height of charged particle temperature, can be divided into high-temperature plasma and low temperature plasma.

Plasma radiofrequency ablation starts to apply early than nineteen ninety-five, in nineteen ninety-five, first hand company successfully registers listing use at U.S. FDA, in 1997, be widely used in medical industry, China's radiofrequency ablation therapy technology almost starts to walk with international upsurge simultaneously, introduce external multiple radio-frequency (RF) therapy equipment, promoted the development of China's heat treatment unit.According to U.S.'s calendar year 2001 statistics, at least 200 ten thousand routine plasma radiofrequency ablative surgeries are applied to the surgical operations such as joint, spinal column, skin.China started the research report that has clinical expert report plasma blade to apply under arthroscope in 2003, and in China, on a large scale, had obtained popularization and application in 2005, and obtained numerous clinicists' approval and high evaluation.

Plasma radiofrequency technology is to produce plasma with 100～120KHz ULF radio-frequency (RF) energy exciting media (NaCl), the energy producing by radio-frequency technique interrupts molecular link, protein and other By Direct Pyrolysis is become to O2, CO2, the gases such as N2, thus complete to tissue cut, punch, melt, the several functions such as shrinkage and hemostasis.

Employing bipolar electrode configurations design, mode of operation is divided into and melts, solidifies two kinds of mode of operations, its be designed for soft tissue in surgical operation cutting, melt, solidify with hemostatic treatment etc.

Plasma blade can be treated various diseases for arthrocsopic surgery, at present extensively in clinical practice, adopts ion cutter application for the treatment of joint disease under arthroscope, and good results, has following characteristics:

1, wound is little.Low-temperature plasma radiofrequency ablation surgery systems, utilize bipolar design, enough radio-frequency (RF) energy are applied on the conductive liquid between ablating electrode and tissue, be ionized into plasma, accelerated particle under electric field in plasma, strikes off the intracellular molecular link of target tissue, causes its decomposition and obtains effective tissue and subtract and hold and eradicating efficacy, because of the heat effect of electric current, complete the hemostatic function to medium and small blood vessel simultaneously.Isoionic energy can not strike off myelin molecular link, and when energy setting is lower than forming the required energy thresholding of plasma, target tissue generates heat because of impedance, and the heat effect of generation can be applicable to hemostasis and tissue contracts.

2, post-operative complication is few.Synovium of joint hypertrophy is fine hair shape; endochrome is calm; and see a large amount of foamy cell hypertrophy; plasmocyte infiltrating; common arthroscope planing tool excision synovial membrane exists synovial membrane damage large; intra-articular hemorrhage is many; postoperative synovial membrane increases the weight of edema, and postoperative easy generation joint accretion operation often can cause serious joint function disturbance and invalidity, affects surgical effect; due to the vaporization at low temperatures of ion cutter; wound is little, can thoroughly excise whole IA pathological changes synovial membrane, and knee joint postoperative edema obviously alleviates; reduce the incidence rate of ankylosis, recover to greatest extent function of joint.

3, the hospital stays short, leave the bed early, rehabilitation is fast.More contribute to postoperative early rehabilitation to take exercise, lose little after-operation response slight in art, patient Geng Yi coordinates early functional exercise, postoperative 3 days can out-of-bed activity.

Therefore, it is quite ripe that plasma radiofrequency ablation techniques is used for the treatment of the fields such as joint, spinal column, is operation tool more conventional in surgical operation.

Yet, existing low-temperature plasma equipment, the switching of its output energy size and the output of energy mainly rely on the operation push-button on foot switch and low-temperature plasma device Host panel to realize, and doctor, when using electrode assembly treatment patient, must step on foot switch; While switching the gear for the treatment of energy, must observe the display floater of main frame simultaneously, cause the inconvenience of operation, increase doctor's labor intensity.
