The changeable claw-shaped electrode device is a minimally-invasive-surgery instrument which is connected with a plasma generator after a path hole is formed in the knee joint under the observation of an arthroscope and emits plasma energy from electrodes at the head in a twin pole mode to treat osteoarthropathy. The electrode device comprises the electrodes, a sleeve pipe, a handle, a manual controller, a sucking pipeline and a cable. The electrode is claw-shaped, and the number of claws is even; when not used, the claw-shaped electrodes are accommodated inside the sleeve pipe; during operation, the claw-shaped electrodes are pushed out of the end of the sleeve pipe to be in a full covering, first side covering or second side covering mode. The meniscus is positioned at the knee joint and is small in space; the number of the electrodes of the changeable claw-shaped electrode device can be adjusted according to the size of the joint cavity so as to adapt to injury cutting of the medial meniscus and the lateral meniscus, and the changeable claw-shaped electrode device can enter narrower space to treat after the electrodes on one side are opened.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular to a kind of type variable claw type electrode assembly for Wicresoft's injury of the bone treatment of joint disease.
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 interactional charged particles, consist of has a system that macroscopical space-time is blunt.At the beginning of 21 century, plasma radiofrequency is used in electrosurgery, and its various advantages embody gradually.Plasma radiofrequency is the energy that utilizes bipolar radiation to produce, convert the electrolyte between radio frequency cutter head and tissue to plasma foil, charged particle in plasma by electric field acceleration after, by energy delivery, give tissue, in the target tissue that dissociates, form the molecular link of cellular elements, the cell in target tissue is disintegrated with minute subunit, be decomposed into carbohydrate and oxide, and cause tissue coagulation downright bad, and slough comes off or produces cicatrix and shrinks, and formative tissue volume subtracts the perhaps effect of cutting.
Meniscus is 2 meniscate fibrous cartilagees, is positioned at the articular surface in medial side of tibial plateau and outside.Its transverse section is triangular in shape, outer thick interior thin, is slightly spill above, to match with condyle of femur, is flat below, joins with tibial plateau.Such structure makes condyle of femur on tibial plateau, form a darker depression just, thereby the stability of spherical condyle of femur and tibial plateau is increased.Medial meniscus is connected with medial collateral ligament, and therefore meniscal activity is restricted, and easily causes damage when knee joint increases mobility.Traditional treatment meniscus method is operative treatment, but operation itself is once well-regulated larger wound, and the postoperative knee joint function of a few peoples there will be to a certain degree limited.The features such as plasma ablation techniques has Wicresoft's wound, easy to operate, are expected to become the alternative meniscal effective ways of traditional operation treatment.At present, plasma ablation techniques is mainly used in Wicresoft and hinders human body soft tissue treatment, as tumor, blood vessel and nerve etc.The radio-frequency ablation electrode product of prior art mostly is fixed scattering shape electrode, operates more singlely, is not suitable for the Resection in Treatment of the meniscus injury of narrow space.
Therefore, those skilled in the art is devoted to develop a kind of simple in structure, easy to operate, plasma electrode device that wound is small, safe, for meniscal minimally-invasive treatment.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of electrode assembly for human bone joint ablation, be applicable to the ablative surgery of the interior injury of lateral meniscus of narrow space, there is the advantages such as simple to operate, various informative, wound is small, safety is high.
