Gastrointestinal catheter inserting device with electromagnetic steering function

Abstract

The invention discloses a gastrointestinal catheter inserting device with an electromagnetic steering function. The gastrointestinal catheter inserting device comprises a hemispherical guiding cap, an assembly plate and a catheter body; the front end of the catheter body is connected with a connecting sleeve fixed to the rear end of the assembly plate; the front end of the assembly plate is provided with a steering plate; the front end of the steering plate is connected with the hemispherical guiding cap; and the front end of the hemispherical guiding cap is provided with a guiding cone rod. A guiding ball is arranged at the front end of the guiding cone rod; and a spherical joint is arranged in the middle of the front end of the assembly plate. A joint clamping sleeve is arranged in the middle of the rear end of the steering plate and arranged on the spherical joint in a clamped mode. Shaking of the steering plate in any direction relative to the spherical joint in the middle of the front end of the assembly plate is facilitated, and guiding of the hemispherical guiding cap connected at the front end of the steering plate is facilitated; wires of coils in an insulating sleeve are clamped together through wire buckles, and thus wire loosening is avoided; and when the coils are powered on, magnetic fields generated by the coils magnetize iron cores on the coils, the iron cores attract iron blocks at the front ends of the iron cores, thus the steering plate is deflected, and insertion orientation of the catheter body is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastrointestinal catheter insertion device with an electromagnetic steering function. Background technique [0002] At present, medical diagnosis and treatment are convenient, and gastrointestinal diseases are frequently-occurring diseases. Diagnosis and treatment of gastrointestinal diseases requires the use of gastric tubes or esophagoscope tubes to be inserted into the intestinal tract for treatment or inspection. The currently used insertion catheter is usually a flexible tube structure, with a guide wire inside to make it inserted. However, during the insertion process, due to the soft front end of the guide wire or catheter, the direction of the catheter insertion process cannot be controlled, and the catheter appears. Or the front end of the guide wire is coiled in the intestinal tract and cannot be inserted further; when the front end of the guide wire or cathet...

Problems solved by technology

The currently used insertion catheter is usually a flexible tube structure, with a guide wire inside to make it inserted. However, during the insertion process, due to the soft front end of the guide wire or catheter, the direction of the catheter insertion process cannot be controlled, and the catheter appears. Or the front end of the guide wire is coiled in the intestinal tract and cannot be inserted further; when the front end of the guide wire or catheter is hard, the direction of the catheter cannot be adjusted during the insertion process, and even the front end of the catheter or guide wire penetrates or cuts the intestinal mucosa. , not suitable for use in existing catheterization therapy
