Embodiment

[0042] like Figures 1 to 11 As shown, a balloon catheter 10 of the present scheme includes: body 11 and a catheter. The conduit is inserted into the body 11, the body 11 is held by the staff, and the catheter is mounted on the body 11 for surgical treatment. Among them, the catheter includes: inner tube 12 and outer tube 13. The inner tube 12 is used to input one of the developer, a guide wire cavity or a laminated conduit 41. That is, the balloon catheter 10 can input the developer, the guide wire or the laminated catheter 41, which is convenient to use according to the work object. The outer tube 13 is mounted on the body 11, the inner tube 12 is inserted from one end of the body 11 and inserted into the outer tube 13, i.e., after the installation is completed, the outer tube 13 is a periphery of the inner tube 12. One end of the outer tube 13 is provided with an inner balloon 15 and an outer balloon 16. The inner balloon 15 expands after inflation causes the outer wall of the i...

Abstract

The invention discloses a balloon catheter comprising a main body and a catheter. The catheter comprises an inner tube and an outer tube. An inner balloon and an outer balloon are arranged at one end of the outer tube. A plurality of temperature sensing elements are uniformly distributed on the inner wall of the inner balloon. A plurality of mapping flexible electrodes are uniformly distributed on the outer wall of the outer balloon. An inner balloon pressure sensor and an inter-outer balloon pressure sensor are arranged in the main body. Pressure in the inner balloon is adjusted in real time by detection data from the inner balloon pressure sensor. Pressure in the space between the inner balloon and the outer balloon is monitored in real time through detection data from the inner balloon pressure sensor and the outer balloon pressure sensor. According to the balloon catheter, the mapping function and the freezing function are integrated in the same catheter, thereby saving operation time, and achieving accurate and real-time detection of temperature at an ablation part of the human body. The balloon catheter has higher safety performance, and can monitor use condition of the inner balloon, thereby further improving practicability and safety of the catheter.

Description

Technical field [0001] The present invention relates to the field of medical freezing ablation, and more particularly to a balloon catheter. Background technique [0002] The existing medical catheter structure is simple, and the internal pressure detection position of the balloon is the equipment inlet and the return end, and the pressure of the balloon is determined by the return gas pressure and the input gas flow, and it is impossible to detect the balloon pressure. It is the difference in the detected pressure value and the pressure value of the actual use area, and the detection value is not accurate, so that the safety of the balloon is not high. At present, the standard tube and freezing catheter used in the treatment of freezing ablation are 2 surgical consumables, which need to be pre-assembled before surgery, and the standard catheter uses proximal locking mode, and it needs to be repeated when the balloon moves, increases Surgical duration and risk. In addition, the e...
