Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Example 1

When the gastroscope is used, the gastroscope is arranged in the inner cavity of the catheter, and then the front end of the catheter is inserted into the esophagus of a patient, so that the gastroscope passes along with the catheter, and compared with the gastroscope which is only used, the gastroscope can reduce edema of the larynx and stimulation of mucous membrane; then the tail end of the vent pipe is communicated with external expansion equipment, when the patient encounters a narrower esophagus, the expansion balloon can be inflated to expand the expansion balloon, when the expansion balloon expands, the esophagus of the patient can be expanded and supported, and an enough implementation space can be provided for an operation, so that a gastroscope can pass through the expansion balloon more easily, and the convenience and the safety of the operation are improved; in order to improve the stability of the catheter and avoid the phenomena of shaking or slipping and the like, the fixing balloon is arranged on the catheter in a sliding mode, specifically, the fixing balloon can be fixed at the oral cavity by sliding the position of the fixing balloon along the catheter, and the outer diameter of the fixing balloon is gradually reduced from the rear end to the front end, so that the catheter can be further fixed, the catheter is more stable, and the gastroscope can be used more stably when passing through the catheter.

In addition, because the external diameter of fixed sacculus reduces by the rear end to front end direction gradually, also can be adapted to the oral cavity of the different degree of depth and width like this for all can the adaptation to different patients, improved application scope and convenience.

In addition, because the inner tube and the catheter are arranged in a non-coaxial manner, preferably, in the embodiment, one side of the inner tube is arranged in a tangent manner with the inner wall of the catheter, it should be noted that the inner diameter of the inner tube is not smaller than the outer diameter of the ultrafine gastroscope, and the inner diameter of the catheter is far larger than the inner diameter of the inner tube; thus, enough space can be left for the inner cavity of the catheter to pass other instruments at the same time, such as: can run through superfine gastroscope in inner tube inner chamber, run through foreign matter pincers or biopsy forceps or conventional gastroscope in catheter inner chamber, be fit for many mirrors and unite, can carry out the operation through multiple scope equipment simultaneously like this, improve doctor's operation efficiency greatly, have better security and convenience simultaneously.

In this embodiment, the outer diameter and the inner diameter of the catheter gradually decrease from the rear end to the front end, and it should be noted that the minimum inner diameter is larger than the diameter of the ultra-fine gastroscope; therefore, the thinner end of the front end can be smoother when entering the esophagus, and the rear end can also give better supporting strength, so that the catheter is more stable when entering the esophagus.

In this embodiment, the tip of the catheter has a bevel cut, which makes the cross-sectional area of the tip of the catheter larger and makes the ability of sucking foreign matters stronger; meanwhile, the oblique cut is beneficial to smoothly entering the esophagus and smoothly passing through the tortuous or narrow esophagus in the using process, and the oblique cut at the head end of the catheter is made of soft materials, so that the flexibility of the catheter can be improved, the esophagus is not damaged, and the narrow esophagus can be followed.

In this embodiment, the fixed balloon has a conical shape or a truncated cone shape.

In the embodiment, the surfaces of the tube, the expansion balloon, the fixed balloon and the inner tube are all made of hydrophilic materials, so that the tube, the expansion balloon, the fixed balloon and the inner tube are convenient to lubricate; specifically, it may be one or more of polyether-amino block copolymer resin, nylon resin, polyimide resin, polyurethane, polytetrafluoroethylene, and polyether ether ketone.

In this embodiment, the inflated shape of the dilatation balloon is circular, elliptical, cylindrical or dumbbell-shaped, and different shapes can improve the occlusion or dilatation effect of the dilatation balloon at different positions of the esophagus.

In this embodiment, the catheter tip is further provided with a developing ring; when the X-ray machine is used for shooting a human body, the developing ring can image, so that a doctor can know the position of the front end of the catheter, and the medical treatment or the foreign matter taking-out of a diseased part is facilitated.

In this embodiment, the outer surface of the catheter is provided with scale marks, so that a doctor can know the insertion length of the catheter conveniently to position the dilatation balloon and the fixation balloon.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
