Problems solved by technology

[0010] In the studies conducted by previous scholars, some directly expanded the multi-stage balloon directly, and some changed the actual length of the balloon by adjusting the external mobile device pre-placed outside the balloon cavity; but the above-mentioned design and method may guarantee the overall While expanding the length

Example Embodiment

[0020] The length-adjustable esophageal balloon catheter of the present invention includes a catheter body 1, at least two balloons 3, a balloon injection port 7, and a guidewire channel injection port 9. The number of the balloon injection ports 7 is the same as the balloon 3 The number of the at least two balloons 3 is the same, and the at least two balloons 3 are arranged in order along the axial direction of the catheter body 1. When the balloon 3 is injected with fluid and expands outward, a balloon cavity 31 is formed between the catheter body 1 and the balloon 3; The catheter body 1 is provided with a guide wire channel 11 and a balloon filling channel 12, the number of the balloon filling channel 12 is the same as the number of the balloon 3; one end of the guide wire channel 11 is connected to the guide wire channel injection port 9 One end of the balloon filling channel 12 is connected with a balloon injection port 7 and the other end is connected with an inner balloon...

Abstract

A length adjustable and controllable esophageal balloon catheter for treating narrow or occlusive lumen of the esophagus is disclosed, and relates to the technical field of the medical apparatus. The length adjustable and controllable esophageal balloon catheter comprises a catheter body, a developing ring, at least two balloons, a balloon cavity, a balloon filling channel, a balloon filling opening, a guide wire channel and a guide wire channel filling opening. The balloon filling opening, the balloon filling channel and the balloons are same in quantity. The lengthy cylindrical or spindle-like balloons are same in diameter and arranged axially along the catheter body orderly. In the invention, the balloon at the tail end is filled first and adjacent balloons are filled orderly on this basis so as not to change the balloon catheter to directly prolong the integral length of the balloon on the basis that the balloon at the tail end is expanded to continuously and synchronously expand pathological changes; the length adjustable and controllable esophageal balloon catheter reduces, and even avoids moving and changing the balloon catheter repeatedly, lowers the medical cost, simplifies the operating steps, reduces the operating complexity and the complication occurrence, lessens X-ray exposure of medical personnel and patients and alleviates the pain of patients.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a novel length-adjustable balloon catheter for dilating esophageal lumen stenosis or occlusion. Background technique [0002] Endoluminal angioplasty is currently a commonly used minimally invasive treatment method for the treatment of lumen stenosis or occlusion. It has the advantages of small trauma, quick onset, safety and reliability, short operation time and hospitalization time, and simple operation. It is widely used in clinical practice. [0003] Balloon catheter is the main instrument of endoluminal angioplasty, which can be used alone or with stent to treat intraluminal stenosis or occlusion. [0004] Vascular and non-vascular luminal stenosis or occlusion have different requirements for balloon catheters due to differences in the structure of the lumen itself and the cause of the lesion. [0005] The esophageal wall contains multiple layers of cros...
