Problems solved by technology
[0003] At present, this kind of ablation operation is performed manually by experienced doctors. Since it is difficult for human hands to accurately control the adhering force of the catheter tip to human tissue, complications such as perforation and edema often occur in heart and artery ablation operations.

The invention relates to the technical field of medical apparatuses and instruments, and discloses a medical catheter head end capable of measuring pressure. The medical catheter head end comprises an electrode tip arranged on an end of a catheter, and a force-measuring device which is connected with the electrode tip and is used to measure stress size and force directions of the electrode tip. The force-measuring device comprises a deformable body which can deform according to stress variation, and a plurality of strain sensors on the deformable body. The plurality of strain sensors are arranged on the periphery of the deformable body along the length direction of the deformable body. The deformable body and the electrode tip are fixedly connected. The medical catheter head end can improve security of a radiofrequency ablation operation, and provides reliable abutting force data support for doctors.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pressure-measurable medical catheter tip. Background technique [0002] In medical interventional operations, radiofrequency ablation catheters have been widely used at present, and are mainly used in the treatment of atrial fibrillation, arrhythmia, refractory hypertension and other diseases. The method of use is to insert a radiofrequency ablation catheter through the blood vessel into the heart or an artery rich in sympathetic nerves by puncturing the femoral artery or radial artery with the assistance of an X-ray machine, and perform radiofrequency ablation of the lesion. [0003] At present, this kind of ablation operation is performed manually by experienced doctors. Since it is difficult for human hands to accurately control the adhering force of the catheter tip to human tissue, complications such as perforation and edema often occur in heart and artery abla...
