[0002] The femoral artery approach is a routine method for interventional surgery. However, in cancer treatment, continuous perfusion chemotherapy with indwelling arterial catheters presents some disadvantages and risks, such as the need for strict bed rest post-operatively, limited mobility, poor patient comfort, and increased risk of deep vein thrombosis and hypostatic pneumonia due to prolonged bed rest. Compared with the traditional femoral artery approach, interventional surgery via the radial artery approach has advantages such as less trauma, less bleeding, faster recovery, lower complication rate, and no need for prolonged bed rest.

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] The following is combined with Figures 1-3 This invention describes a radial artery puncture and fixation device according to an embodiment of the present invention.

[0046] like Figure 1 As shown, this utility model embodiment provides a radial artery puncture and fixation device, including a base 1, a clamping component 2, and an adjusting component 3;

[0047] One side surface of the base 1 is provided with a fixing area for placing an arm and a mounting groove 11 for placing a palm. The mounting groove 11 and the fixing area are spaced apart along a first direction.

[0048] The clamping component 2 is mounted on the base 1 and is positioned in a corresponding fixed area to clamp the arm;

[0049] Adjustment component 3 is rotatably disposed in the mounting groove 11, and the palm rests on adjustment component 3, which can adjust the tilt angle of the palm.

[0050] Specifically, the patient's arm is clamped and fixed by the clamping component 2 to prevent puncture failure due to the movement of the patient's arm, thereby improving the success rate of puncture and reducing the patient's pain; the tilt of the patient's palm can be adjusted by the adjusting component 3, which makes it easier for medical staff to perform puncture operations at different angles and has a high degree of flexibility.

[0051] In some possible implementations, the base 1 can be a rectangular body, and the mounting groove 11 can be opened along the length direction and vertical direction of the base 1. The side wall edges of the mounting groove 11 can be rounded, which is aesthetically pleasing and can also prevent the patient's palm from being cut by sharp edges.

[0052] like Figure 2 As shown, a radial artery puncture and fixation device according to an embodiment of the present invention includes a clamping assembly 2 comprising a rod 21 and a clamping member 22.

[0053] The rod 21 is symmetrically arranged on the base 1 along the first direction;

[0054] The clamping member 22 is movably connected to the rod body 21 on both sides, so that the clamping member 22 can move along the axial direction of the rod body 21.

[0055] In some possible implementations, the rod 21 can be plugged into and fixed to the base 1. The clamping member 22 can be a plate-shaped or rod-shaped member, as long as it can be movably connected to the rod 21 and can slide axially in the rod 21. It should be understood that in order to improve the clamping effect of the clamping member 22, a snap-fit ​​structure can be added to the clamping member 22 so that the clamping member 22 can be fixed at a certain position on the rod 21, or external force can be manually applied to the clamping member 22 to enhance the fixing effect of the arm.

[0056] According to an embodiment of the present invention, a radial artery puncture and fixation device is provided, wherein the clamping member 22 further includes: an adjusting block 221 and at least two pressure rollers 222;

[0057] Adjusting block 221 is sleeved on rod 21 and threadedly connected to rod 21;

[0058] Two pressure rollers 222 are arranged sequentially along the first direction, and the two ends of the pressure rollers 222 are rotatably connected to the adjusting block 221 respectively;

[0059] The rod 21 has a rotating part 23 at the end away from the base 1, and the end of the rod 21 away from the rotating part 23 is rotatably connected to the base 1.

[0060] It should be understood that when the patient's arm is inserted under the clamping assembly 2, manually rotating the rotating part 23 will cause the rod 21 to rotate. Since the rod 21 is rotatably connected to the base 1, the rod 21 only rotates in place with its axis as the axis. However, since the adjusting block 221 is threadedly connected to the rod 21, the circumferential displacement of the rod 21 will be converted into the axial displacement of the adjusting block 221, which will cause the adjusting block 221 to descend. The adjusting block 221 will drive the rotating pressure roller 222 to descend synchronously. At least two pressure rollers 222 are arranged in parallel, which can increase the contact area with the patient's arm, reduce local pressure, and reduce the patient's discomfort.

[0061] According to an embodiment of the present invention, a radial artery puncture and fixation device, the clamping member 22 further includes:

[0062] A protective sleeve is fitted onto the surface of the pressure roller 222;

[0063] The protective sleeve is a flexible protective sleeve that provides cushioning between the patient's arm and the pressure roller 222.

[0064] In some possible implementations, the protective sleeve is made of cushioning foam, which is soft and porous, and has a certain degree of deformation and cushioning capacity, which can further improve the comfort of the pressure roller 222 in contact with the patient's arm.

[0065] A radial artery puncture and fixation device according to an embodiment of the present invention further includes:

[0066] A locking part is provided at the connection between the clamping member 22 and the rod body 21 to fix the position of the clamping member 22 on the rod body 21.

[0067] In some specific embodiments, the clamping member 22 may include a connecting ring, which is sleeved on the rod body 21. The locking part may be a limiting pin, the end of which passes through the connecting ring and extends to the surface of the rod body 21. The limiting pin is threadedly connected to the connecting ring. By tightening the limiting pin, the limiting pin can be pressed against the surface of the rod body 21, thereby fixing the position of the clamping member 22 on the rod body 21.

[0068] In some other embodiments, the locking part can also form a mating relationship with the rod 21. For example, the locking part can be provided with a telescopic pin, and the rod 21 has spaced limiting holes. When the fastener moves to the corresponding limiting hole, the pin on the locking part is inserted into the limiting hole to fix the position.

[0069] It should be understood that there are many other structural forms of locking parts, which will not be listed here, as long as they can fix the position of the fastener on the rod 21.

[0070] like Figure 3 As shown, according to an embodiment of the present invention, a radial artery puncture and fixation device includes an adjustment component 3 comprising: an adjustment shaft 31, a rotating arm 32, and an adjustment plate 33.

[0071] The two ends of the adjusting shaft 31 are rotatably connected to the side walls of the mounting groove 11 located on both sides in the first direction;

[0072] One end of the rotating arm 32 is fixedly connected to the adjusting shaft 31;

[0073] The adjusting plate 33 is connected to the end of the rotating arm 32 away from the adjusting shaft 31.

[0074] Specifically, the rotating arm 32 can rotate around the adjusting shaft 31 with its own length as the radius, while driving the adjusting plate 33 to rotate, thus realizing the change of the angle of the adjusting plate 33.

[0075] In some possible implementations, two rotating arms 32 are provided, the two support arms are symmetrically arranged along the first direction, and the length direction of the support arms is perpendicular to the length direction of the adjusting plate 33.

[0076] In some other embodiments, a damping structure may be added at the connection between the rotating shaft and the mounting groove 11 to increase the rotational stability of the rotating arm 32 and facilitate its position holding.

[0077] A radial artery puncture and fixation device according to an embodiment of the present invention further includes:

[0078] The fixing strap 4 is set on the adjustment plate 33 and is used to fix the patient's palm.

[0079] In some possible implementations, the two ends of the fixing strap 4 are respectively connected to both sides of the adjusting plate 33 along its length. The fixing strap 4 is a Velcro strap, which can adjust the binding length and tightness. The fixing strap 4 is a ring structure that wraps around the patient's palm and is fixedly attached to the adjusting plate 33, thereby limiting and fixing the patient's palm and preventing the patient's palm from moving.

[0080] According to an embodiment of the present invention, a radial artery puncture and fixation device, the adjusting component 3 further includes:

[0081] Worm gear 34 is sleeved on adjusting shaft 31;

[0082] The worm 35 has one end meshing with the worm wheel 34, and the other end of the worm 35 passes through the base 1 in a first direction and is rotatably connected to the base 1.

[0083] Specifically, the worm gear 34 and the worm 35 can be connected by a common meshing method, that is, the straight line of the rotation axis of the worm gear 34 is perpendicular to the straight line of the rotation axis of the worm 35.

[0084] A radial artery puncture and fixation device according to an embodiment of the present invention further includes:

[0085] Knob 5 is located on the side of the base 1 away from the mounting groove 11, and knob 5 is connected to the end of the worm 35 away from the worm wheel 34, for rotating the worm 35.

[0086] Specifically, knob 5 is coaxially connected to worm gear 35. Rotating knob 5 will drive adjustment component 3 to work. Worm gear 35 of adjustment component 3 rotates, which drives worm wheel 34 to rotate. Worm wheel 34 drives adjustment shaft 31 to rotate, adjustment shaft 31 drives support arm to swing, support arm drives adjustment plate 33 to change tilt angle, and adjustment plate 33 in turn drives palm to adjust angle synchronously, which facilitates puncture operation by medical staff.

[0087] A radial artery puncture and fixation device according to an embodiment of the present invention further includes:

[0088] Pad 6, located in a fixed area on one side surface of base 1, provides cushioning for the arm.

[0089] In some possible implementations, the pad 6 is made of elastic sponge or other elastic material, and its upper surface is concave to conform to the physiological curvature of the human arm, improving patient comfort when placing their arm. Furthermore, a cleaning sleeve can be fitted onto the surface of the pad 6. This sleeve can be made of disposable or reusable cloth, and can be washed or replaced according to medical standards, preventing cross-infection caused by dirt on the pad 6 while improving the patient's experience. Additionally, the pad 6 can be detachably fixed to the surface of the base 1 using Velcro or similar methods, facilitating easier replacement.

[0090] It should be understood that the first direction refers to the direction of the patient's arm extension when the aforementioned radial artery puncture fixation device is used.
