Embodiment Construction

[0031] The present invention will be further described in detail below through the accompanying drawings and specific embodiments.

[0032] like figure 1 , 7 As shown, in an embodiment of the interventional catheter controller of the present invention, the interventional catheter controller includes a handle 1, a main shaft 11 fixed on the handle 1, a locking member 2 disposed on the main shaft 11, a first A runner 4 , a second runner 3 and an end cover 5 .

[0033] The distal end of the main shaft 11 is used to access the pulling wire 7 of the sheath tube 6 . The main shaft 11 is provided with two slots 110 for introducing and connecting to the first runner 4 and the second runner 3 respectively. of the four traction lines 7. Of course, the number of runners may be three or more, and the number of slots 110 on the main shaft 11 corresponds to more, ensuring that each runner corresponds to one slot 110 .

[0034] like Figure 5 , 6 As shown, a support member 8 is provide...

Abstract

The invention discloses an interventional catheter controller which comprises a handle, a main shaft fixed to the handle, a locking piece arranged on the main shaft, at least one rotating wheel and a pull wire arranged at the far end of the main shaft and used for being connected into a sheathing canal, a supporting piece is arranged on the main shaft, and the pull wire bypasses the supporting piece and then is connected to the rotating wheel. When the rotating wheel and the supporting piece rotate relatively, the traction line can be pulled. And the locking piece can be close to and tightly pressed on the rotating wheel so as to lock the rotating wheel. By the adoption of the technical scheme, according to the interventional catheter controller, the traction length of the traction line is controlled by rotating the rotating wheel, so that control over the sheathing canal can be achieved, the rotating wheel can be locked through the locking piece after adjustment is completed, single-hand adjustment control can be achieved by holding the handle, and the interventional catheter controller is very convenient to use.

Description

technical field [0001] The invention relates to an interventional catheter controller, which belongs to the technical field of medical equipment. Background technique [0002] In current radiofrequency ablation, doctors need to use X-rays and a three-dimensional mapping system to roughly determine the position of the catheter in the heart, but cannot directly see whether the catheter is really attached to the target structure. Intracardiac ultrasound technology or OCT technology can help interventional doctors to see the structure of the heart more intuitively, and can also more accurately locate the position of the ablation catheter, which provides a powerful guiding role for radiofrequency ablation. Since the situation in the heart cavity can be known in real time, intracardiac ultrasound imaging or OCT imaging can guide the whole process of ablation in real time like fluoroscopy, and can display the situation of the catheter in real time, which significantly improves the ...
