Description

Technical Field

[0001] This utility model relates to the field of medical balloon technology, specifically to an anti-slip dilatation balloon. Background Technology

[0002] In gastroenterology, dilatation balloons are used to dilate the digestive tract, facilitating the entry of medical instruments or the removal of foreign objects. However, when a dilatation balloon is inserted into the digestive tract, peristalsis within the body can cause it to slip. Due to the smooth surface of the balloon, it is impossible to prevent it from slipping out after placement. Generally, after slippage, the balloon needs to be repositioned, increasing the patient's pain. Furthermore, the dilation of a regular balloon can also obstruct the air pressure flow between the two sides, creating a pressure difference that causes pain and harm to the patient.

Both ends of the balloon are fixedly connected to the sheath and the soft tip, respectively. Fiber lines are provided on the surface of the balloon. The fiber lines are divided into transverse limiting lines and longitudinal limiting lines. The limiting lines cooperate with the balloon to make the surface of the balloon have a wavy structure.

[0007] Furthermore, both the lateral limiting line and the longitudinal limiting line are multiple lines evenly and equidistantly distributed.

[0008] Furthermore, the intersection of the lateral limiting line and the longitudinal limiting line is knotted and fixed.

[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Combined with appendix Figure 1-7An anti-slip dilatation balloon consists of a sheath 1, a balloon 2, a soft head 3, and a limiting line 4 set on the balloon. The limiting line 4 is distributed on the balloon 2, which causes the balloon 2 to deform and form a wave-shaped structure on the surface of the balloon 2. The wave-shaped structure formed on the surface of the balloon 2 increases the friction of the balloon 2, so that the balloon 2 will not slip in the digestive tract.

[0029] The balloon 2 is mounted on the sheath 1. The end of the sheath 1 is provided with a soft head 3. One end of the balloon 2 is heat-fused to the sheath 1, and the other end of the balloon 2 is heat-fused to the soft head 3. The sheath 1 is connected to the balloon 2. Air is inflated into the balloon 2 through the sheath 1, thereby inflating the balloon 2.

[0030] The balloon 2 is heat-fused to the sheath 1, and the soft tip 3 is then welded to the other end of the balloon 2. The soft tip 3 is used to facilitate the insertion of the sheath 1 into the digestive tract when the balloon 2 is not inflated. One end of the limiting line 4 is fixedly connected to the heat-fused welding point between the balloon 2 and the sheath 1, and the other end of the limiting line 4 is fixed to the heat-fused welding point between the soft tip 3 and the balloon 2.

[0031] The limiting line 4 is divided into a transverse limiting line 41 and a longitudinal limiting line 42. Both the transverse limiting line 41 and the longitudinal limiting line 42 are evenly distributed on the surface of the balloon 2. The two ends of the transverse limiting line 41 are connected to the heat-fusion fixing position between the balloon 2 and the sheath 1, and the heat-fusion fixing position between the balloon 2 and the soft head 3, respectively.

[0032] Multiple lateral limiting lines 41 and multiple longitudinal limiting lines 42 are provided, and they are evenly distributed at equal intervals. The multiple lateral limiting lines 41 and multiple longitudinal limiting lines 42 are intersected on the surface of the balloon 2, and the parts where the lateral limiting lines 41 and longitudinal limiting lines 42 intersect are tied together.

[0033] The limiting line can be made of nylon rope, or a non-elastic, high-strength polymer material or metal material.

[0034] The nylon rope can be directly heat-fused and fixed to the sheath 1 and soft head 3 at both ends of the balloon 2.

[0035] When using other wires, the limiting wire 4 is first wrapped around the welding surface of the sheath tube 1, and then the limiting wire 4 is glued and fixed to the sheath tube 1. The limiting wire 4 is first wrapped around the welding surface of the soft head 3, and then the limiting wire 4 is glued and fixed to the soft head 3.

[0036] The limiting line 4 is first wound around the welding surface of the sheath tube 1. The line is then heated to the welding surface of the sheath tube 1 by a heating device to ensure that the welding surface is at the same height as the sheath tube 1. The limiting line 4 is then heated to the welding surface of the soft head 3 by the device to ensure that the welding surface is at the same height as the sheath tube 1, thereby ensuring that the limiting line 4 is completely attached to the surface of the balloon 2.

[0037] In other embodiments, the balloon 2 has a shape with a limiting indentation. The position of the limiting indentation corresponds to the position of the limiting line. When the balloon 2 is inflated, the line is positioned according to the design size of the positioning shape to maintain the design size limit, thereby ensuring that the balloon 2 will not deform and can maintain a large friction positioning effect. In addition, the balloon 2 itself has a limiting indentation, which also reduces the influence of the limiting line 4 on the balloon and prevents the friction surface between the limiting line 4 and the surface of the balloon 2 from being too large, which would lead to the balloon rupture.

[0038] The balloon 2 is made of nylon or modified nylon with good elasticity to prevent the balloon from breaking due to insufficient strength of the line when it is inflated, or the balloon from rupturing due to insufficient flexibility of the line.

[0039] The balloon 2 is marked with a printed color 5. When the doctor inserts the balloon into the lesion, he can use the printed color 5 to judge the insertion depth of the balloon 2. At the same time, he can use the printed color 5 to judge whether the balloon 2 slips out during expansion.

[0040] The wavy edge of balloon 2 increases the friction during movement, preventing balloon 2 from slipping. This effect is mainly achieved by the longitudinal limiting line 42.

[0041] The lateral limiting line 41 on the balloon 2 can establish several channels, which can ensure the air flow on both sides of the balloon 2 when the balloon 2 is inflated, thus maintaining equal pressure on both sides.

[0042] When balloon 2 is inflated and maintained at pressure, the wave shape of balloon 2 can determine whether balloon 2 has slipped, and the insertion depth of balloon 2 can also be determined by the distance of the pre-known wave of balloon 2.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
