[0021] The specific settings and functions of the stabilizing device 3 and the auxiliary device 4 are described in detail below.

[0022] Specifically, the stabilizing device 3 includes a fixing seat 32, which is fixedly connected to the inner wall of the vascular sheath body 1, a guide ring 33 is fixedly connected to the surface of the fixing seat 32, a lower plate 34 is fixedly connected to the surface of one side of the guide ring 33, a control member 37 is slidably connected to the inner wall of the vascular sheath body 1, an upper plate 35 is fixedly connected to the surface of the control member 37, a screw 38 is rotatably connected to the inner wall of the vascular sheath body 1, and the screw 38 is threadedly connected to the inner wall of the control member 37.

[0023] In this embodiment: after the catheter body 2 is extended from the vascular sheath 1 into the blood vessel, when the catheter body 2 does not need to move, the screw 38 is rotated, and the screw 38 drives the upper plate 35 to move through the control member 37. The upper plate 35 cooperates with the lower plate 34 to clamp the catheter body 2, thereby reducing the instability of the catheter body 2, making it easy to slide in the blood vessel, causing damage to the blood vessel wall, and increasing the risk of surgery.

[0024] Specifically, the upper end of the screw rod 38 is fixedly connected with a rotating wheel 31 , and a non-slip groove is provided on the surface of the rotating wheel 31 . The larger rotating wheel 31 facilitates medical staff to control the rotation of the screw rod 38 .

[0025] Specifically, a plurality of rubber sheets 36 arranged at equal intervals are fixedly connected to the surfaces of the upper sheet 35 and the lower sheet 34 , and the plurality of rubber sheets 36 are arranged in an arc shape.

[0026] In this embodiment, the sliding rubber sheet 36 can fit the surface of the catheter body 2, thereby increasing the friction force and reducing the phenomenon of the catheter body 2 moving forward and backward.

[0027] Specifically, the control member 37 is composed of a threaded sleeve and two guide rods. The two guide rods are slidably connected to the inner wall of the vascular sheath 1. The threaded sleeve in the control member 37 can cooperate with the screw 38 for transmission, and the guide rods can provide guidance to improve stability.

[0028] Specifically, the auxiliary device 4 includes a rotating seat 41, which is fixedly connected to the surface of the vascular sheath 1. The inner wall of the rotating seat 41 is rotatably connected to a rotating member 45, and the surface of the rotating member 45 is fixedly connected to a hollow plate 42. A threaded groove 47 is provided on the surface of the rotating member 45, and a nut 46 is threadedly connected to the threaded groove 47 on the surface of the rotating member 45.

[0029] In this embodiment: after the vascular sheath 1 is inserted into the blood vessel, there is a certain height between the outer end of the vascular sheath 1 and the patient's skin. The hollow plate 42 is rotated to make the hollow plate 42 fit vertically with the patient's skin, and then the nut 46 is rotated to make the nut 46 abut against the surface of the rotating seat 41 to achieve positioning and support.

[0030] Specifically, the inner wall of the hollow plate 42 is slidably connected with a slide plate 43 , and the support height can be extended by sliding the slide plate 43 in the hollow plate 42 .

[0033] Working principle: When the device is used, the vascular sheath 1 is inserted into the blood vessel, and the catheter is delivered to the blood vessel to deliver the filler for surgery. By setting the stabilizing device 3, when the device needs to be used, the catheter body 2 does not need to be moved, and the rotating wheel 31 and the screw 38 are pushed to rotate. The screw 38 drives the upper piece 35 to move through the control part 37. The upper piece 35 cooperates with the lower piece 34 to clamp the catheter body 2. The rubber piece 36 on the surface of the upper piece 35 and the lower piece 34 can increase the friction force, thereby positioning the catheter body 2. By setting the stabilizing device 3, it is convenient to assist the interventional catheter in positioning, which can effectively reduce the situation in which the existing interventional embolization delivery device is used to deliver the interventional catheter. When the interventional catheter does not need to move, it is easy to accidentally touch it, causing the interventional catheter to slide, thereby colliding with the blood vessel wall to cause damage, increasing the risk of surgery, and thus improving the overall stability of the device.

[0034] By setting the auxiliary device 4, when the equipment needs to be used, the slide plate 43 is slid in the hollow plate 42, and after sliding to a certain position, the slide plate 43 is positioned by the clamping member 44 inserted into the clamping groove on the surface of the hollow plate 42, and the hollow plate 42 and the slide plate 43 are driven to rotate by the rotating member 45, so that the slide plate 43 fits the patient's skin, and the nut 46 is rotated to make the nut 46 abut against the surface of the rotating seat 41 for positioning, thereby supporting the vascular sheath 1. By setting the auxiliary device 4, the auxiliary equipment is convenient to use, which can effectively reduce the situation that when the existing interventional embolization catheter delivery device is in use, there is a certain height between one end and the patient, and it is easy to curl up when pressed, causing damage to the blood vessel and endangering the patient's health, thereby improving the overall practicality of the equipment.
