Description

Technical Field

[0001] The utility model relates to the technical field of medical catheters, in particular to a medical catheter with a changeable tip direction. Background Art

[0002] Medical catheters are flexible tubular devices used to guide and deliver drugs, liquids or gases, as well as to perform diagnostic or therapeutic operations. They are widely used in the medical field for various medical procedures. Medical catheters are usually made of flexible biocompatible materials such as polyurethane, silicone or polyethylene, which can guide the catheter in the body without causing allergic or rejection reactions.

[0003] When adjusting the direction of the existing medical catheters on the market, the traction rope is generally used to pull the tube head to deform it and then change the direction. However, after the traction rope is released, the tube head will immediately return to its original position. In this way, during operation, if the medical staff suddenly loses their hands, the tube head will be adjusted backwards, which may easily cause damage to the patient's body. For this reason, we propose a medical catheter with a changeable tip direction. Utility Model Content

[0026] In this embodiment, the device is provided with four auxiliary pipe heads 5 on the four sides of the middle of the six-way pipe sleeve 3, and the four auxiliary pipe heads 5 are each provided with a plug 6 inside. When adjusting the direction of the cone head 2, it can be changed in four directions, which provides higher flexibility during adjustment.

[0027] like Figure 3 and Figure 4 As shown, the tube body 1 is provided with expansion slots 8 on the four sides of one side close to the cone head 2, and the inner walls of the four expansion slots 8 are integrally formed with first hanging heads 9, and a wire groove 10 is provided between the expansion slots 8 and the auxiliary tube head 5, and a rotation slot 701 is provided at one end of the inner side of the auxiliary tube head 5, and the cannula 6 is located at the outer wall of one end of the rotation slot 701 and fixedly connected with the second hanging head 702, and the second hanging head 702 is connected to the first hanging head 9 through a traction line 703;

[0028] In this embodiment, when adjusting the direction, the insert tube 6 at the corresponding position is twisted, and the insert tube 6 drives the second hanging head 702 located on one side of the rotating groove 701 to rotate synchronously. When the second hanging head 702 rotates, the traction line 703 is wound up. After the traction line 703 is wound up, the first hanging head 9 inside the telescopic groove 8 is pulled, so that the bottom end of the tube body 1 is adjusted in the direction of the force. When the auxiliary tube head 5 is loosened, the traction line 703 will not automatically extend, which can avoid damage.

[0029] like Figure 3 As shown, a movable ring 11 is fixedly connected to the outer side of the middle part of the cannula 6, and a movable groove 12 is opened on the inner side of the middle part of the auxiliary tube head 5, and the movable ring 11 is movably connected to the movable groove 12;

[0035] Working principle: when adjusting the direction, twist the cannula 6 at the corresponding position, and the cannula 6 drives the second hanging head 702 located on one side of the rotating groove 701 to rotate synchronously. When the second hanging head 702 rotates, the traction line 703 is rolled up. After the traction line 703 is rolled up, the first hanging head 9 inside the telescopic groove 8 is pulled, so that the bottom end of the tube body 1 is adjusted in the direction of the force. When the auxiliary pipe head 5 is released, the traction line 703 will not automatically extend, thus avoiding damage. The device is provided with four auxiliary pipe heads 5 on the four sides of the middle part of the six-way pipe sleeve 3, and the four auxiliary pipe heads 5 are all provided with cannulas 6.
