Embodiment Construction

[0020] The present invention will be further described below in conjunction with the drawings and embodiments:

[0021] See attached Figure 1 to 8 , The ultrasound imaging catheter in the figure includes a hollow tube body 1; wherein: the tube body 1 is a medical soft catheter, and a polymer fiber filament 5 is arranged in the tube wall of the tube body 1. 5 overlap each other to form a mesh woven mesh layer, so that an ultrasonic imaging zone with different density is formed between the tube body 1 and the woven mesh layer. In this embodiment, a woven mesh layer composed of polymer fiber filaments 5 is implanted in the tube wall of the soft tube body 1, so that an ultrasonic reflection and scattering interface is formed in the tube body 1 made of plastic, which is beneficial to Determine the position of the entire ultrasound imaging catheter and any part of the ultrasound imaging catheter through medical ultrasound images.

[0022] In order to further enhance the ultrasonic ref...

Abstract

The present invention relates to a medical device, that is, an ultrasonic imaging catheter, which includes a hollow tube body; wherein: the tube body is a medical soft catheter, and polymer material fiber filaments are arranged in the tube wall of the tube body, and the polymer material fiber The wires overlap and intersect each other to form a net-like braided mesh layer, so that ultrasonic imaging areas with different densities are formed between the tube body and the braided mesh layer. Due to the above structure, the catheter of the present invention has simple structure, wide application range, reduced manufacturing cost, improved ultrasonic imaging capability and facilitates catheter tip imaging.

Description

Technical field [0001] The invention relates to a medical device, in particular to an ultrasonic imaging catheter with simple structure, wide application range, lower manufacturing cost, improved ultrasonic imaging capability and favorable for catheter tip imaging. Background technique [0002] Minimally invasive interventional therapy is a new treatment method developed in the medical field in recent decades. Compared with traditional surgery, it has the characteristics of small incision, less trauma, less bleeding, faster recovery, and less pain. Drainage catheters and other interventional catheters involved in minimally invasive interventional treatments need to be guided by X-ray machines, CT, ultrasound and other electronic equipment. Since the strong ionizing radiation generated by X-ray machines and CT harms human health, it is simple and safe to use The monitoring and positioning of ultrasound imaging equipment has become the primary consideration for clinicians. However...
