Embodiment 1

[0027] Embodiment 1, the present application provides a dredging device in a stent or catheter, including a base and a dredging structure, the base is connected to the dredging structure, generally, the dredging structure is made of a flexible material or an elastic material, such as silica gel In order to prevent tissue damage during the dredging process, the matrix is ​​preferably made of elastic material, which is less flexible than the dredging structure.

[0028] The dredging device in the stent or catheter body provided by the present invention controls the movement of the base body through actions such as rotating and pulling the base body, and then controls the dredging structure to dredge the stent or catheter to remove the blockage inside the stent or catheter, thereby making the narrow or blocked pipeline Unobstructed, no need to replace the stent or catheter, saving time and effort, reducing the pain of the patient's operation, and greatly reducing the cost of the p...

Embodiment 2

[0029] Embodiment 2, on the basis of embodiment 1, refer to Figure 1-Figure 3 , the dredging structure is a helical wire 11, the substrate can use a rod 10, and the end of the rod that is not connected with the substrate is equipped with a first handle 12, which is convenient for people to pinch or use tools to clamp, so as to facilitate operation.

[0030] For the convenience of use, a guide wire 101 is connected to the base body, and a handle 102 is fixed at the end of the guide wire not connected with the base body. With this structure, the guide wire can be controlled by the handle to drive the movement of the dredging device, which is more conducive to operation with tools such as endoscopes and duodenoscopes, and is more convenient to use.

[0031] As a preferred solution, the outer surface of the spiral wire is evenly provided with a plurality of grooves 13, and the plurality of grooves are staggered to form a network. In this structure, the network-shaped grooves can ...

Embodiment 3

[0032] Embodiment 3, on the basis of embodiment 1, refer to Figure 4 , the base is a brush rod 15, the dredging structure is bristles 14, and the bristles are fixed on the brush rod to form a brush. Of course, a guide wire may also be connected to the brush rod, and a handle is fixed at the end of the guide wire not connected to the brush rod. As a deformation, see Figure 9 , the brush rod can be provided with a hole 26 for passing a guide wire, so as to be convenient to use.

Abstract

The invention relates to a stent or catheter in-vivo dredging device. The device comprises a base body and a dredging structure arranged on the base body, and the base body is connected with the dredging structure. According to the stent or catheter in-vivo dredging device, by controlling the base body to move, the dredging structure is controlled to dredge a stent or a catheter, and blockage objects in the stent or the catheter are removed, so that a narrow or blocked pipeline gets smooth without replacing the stent or the catheter, the time and effort are saved, the surgical pain of patientsis relieved, and the treatment cost of the patient is greatly reduced.

Description

technical field [0001] The invention relates to the field of a device for dredging a pipeline in a human body, in particular to a device for dredging a stent or a catheter in the body. Background technique [0002] Pipelines in the human body, including blood vessels, bile ducts, esophagus, intestinal tract, gastric cavity, respiratory tract, etc., are narrowed due to various reasons and often lead to diseases. It is often necessary to place stents or catheters in the pipelines of the human body to solve the problem of narrowing of human pipelines. [0003] However, due to various reasons, the stent or catheter is often blocked or narrowed after being used for a period of time, causing the stent or catheter to be blocked. In this case, the current method is to replace the stent or catheter for the patient, which is time-consuming and laborious, which brings pain to the patient, and the cost of replacing the stent or catheter is high. Contents of the invention [0004] The...
