A radiofrequency ablation catheter (100) and a radiofrequency ablation device. The radiofrequency ablation catheter (100) comprises a radially contractible and expandable electrode stent (20), a connecting tube (30), and a core wire (40). The proximal end of the connecting tube (30) is connected to the distal end of the electrode stent (20), and the connecting tube (30) has a first lumen (34) running through the proximal and distal ends thereof. The core wire (40) movably runs through the electrode stent (20) and the first lumen (34). The core wire (40) is provided with a first limiting portion (41), the first limiting portion (41) being located in the first lumen (34); and the inner wall of the first lumen (34) is correspondingly provided with a second limiting portion (35). When the first limiting portion (41) abuts against the second limiting portion (35) and the central wire (40) moves from the distal end to the proximal end, the electrode stent (20) is switched from a contracted state to an expanded state. The radiofrequency ablation catheter (100) can reduce the risk of vascular injury, improve the accuracy of the core wire (40) in accessing a target branch vessel, and thus improve the ablation efficiency of radiofrequency ablation.

The application belongs to the technical field of testing, and specifically provides a simulation device and a testing method for radio frequency ablation instrument testing. The simulation device for radio frequency ablation instrument testing comprises a water pool, a test model, a clamping mechanism and a driving mechanism. The test model is fixed in the water pool, and the driving mechanism drives the catheter to reciprocate along the test channel formed by the test model through the clamping mechanism to perform bending fatigue testing. The test model comprises a first test section and a second test section which are continuous but have opposite bending directions. During testing, the test section of the catheter can be subjected to bending fatigue testing in the first test section and the second test section in turn by changing the stroke range of the reciprocating motion of the test section of the catheter through the driving mechanism, and the rotation or re-clamping of the catheter is not required during the whole process. In this way, the manual operation steps are eliminated, which helps to realize the automation of the testing process, and the unattended operation can be realized during long-term durability testing.

The present application relates to a kind of radio frequency ablation equipment, it includes electrode, balloon and delivery tube;The electrode is in net shape, with the contraction state of being shrunk together when being constrained, and the expansion state of being automatically expanded outward when losing constraint, which is connected with the external electrical connector by electrode lead;The balloon is located in the inside of the electrode, and pushes against the electrode when in the inflation state;The delivery tube includes outer tube and inner tube, and the electrode lead is located between the outer tube and inner tube, and the delivery tube further includes balloon catheter communicated with one end of the balloon, which is located in the inside of the inner tube and has gap between the inner tube.When electrode is delivered to target position, it can be automatically unfolded and form good abutment effect with the inner wall of bronchus by the support of balloon.

This utility model relates to the field of medical aesthetics technology, specifically disclosing an ion radiofrequency ablation device for removing eye bags. The device includes a mask with a first cavity and a second cavity inside. The first cavity is located above the second cavity, and a connecting pipe connects the first and second cavities. An ablation component is located at the rear end of the mask. The ablation component includes a slider movably connected inside the first cavity, a connecting rod fixedly connected to the rear end of the slider, and a circular frame fixedly connected to the rear end of the connecting rod. A sealing block is movably connected inside the second cavity, and an ablation module is fixedly connected to the rear end of the sealing block. When performing ablation for eye bag removal after wearing the mask, the device ensures that the probe remains in close contact with the skin surface, preventing the distance between the probe and the skin from affecting the ablation process and causing burns or scalds, thereby improving the efficiency of the eye bag removal procedure.
