Description

Technical Field

[0001] This utility model belongs to the field of hand support technology, specifically relating to a hand support for contralateral radial artery puncture. Background Technology

[0002] In interventional cardiac procedures, radial artery puncture is routinely performed on the patient's right hand, with the surgeon typically standing on the patient's right side. However, when the right radial artery is not readily accessible, the left radial artery must be used instead. In this case, the surgeon maintains the right-side standing position, and the patient's left hand needs to be raised to the surgical area. However, due to the lack of effective support, the patient's arm tends to droop naturally, leading to fatigue and discomfort from maintaining the same posture for an extended period. Furthermore, the unstable arm position may affect the surgeon's accuracy and efficiency during the puncture. Therefore, a hand support is needed to limit and support the patient's left hand during interventional cardiac procedures.

[0003] Currently, traditional hand supports used for lateral radial artery puncture in clinical practice are mostly fixed structures, which cannot flexibly adjust the arm rotation angle according to the patient's posture and surgical needs, making it difficult to adapt to the needs of different patients. Utility Model Content

[0004] The purpose of this invention is to provide a contralateral radial artery puncture hand support that can adjust the rotation angle of the patient's arm according to the needs of the patient or medical staff when fixing and supporting the patient's arm.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-4 As shown, a contralateral radial artery puncture hand support includes a lower support bracket, an arc-shaped lower seat 5 fixedly connected to the lower support bracket, an arc-shaped groove opened on the arc-shaped lower seat 5, an arc-shaped slide bar 6 slidably connected inside the arc-shaped slide groove, and a locking member adapted to the arc-shaped slide bar 6 installed on the arc-shaped lower seat 5.

[0027] The curved slide bar 6 is internally fixedly connected to a clamping hand rest, which has an exposed empty area.

[0028] At this point, the clamping hand rest is fixed above the hospital bed by the lower support bracket, and then the patient's arm is clamped inside the clamping hand rest, which can stably limit and support the patient's arm. The radial artery puncture site on the patient's side is opposite to the exposed empty area, so that medical staff can perform disinfection, puncture and other operations on the radial artery puncture site on the patient's side.

[0029] Meanwhile, after the patient's arm is clamped, the clamping hand support can be rotated by rotating the arc-shaped slider 6. When the clamping hand support rotates, it will adjust the flipping position of the patient's arm, so that the flipping angle of the patient's arm can be adjusted according to the needs of the patient or medical staff when fixing and supporting the patient's arm.

[0030] One structure of the locking element is disclosed here. The locking element can be a screw threaded onto the arc-shaped lower seat 5. By rotating the screw, the screw and the arc-shaped slide bar 6 are brought into contact, thereby locking the arc-shaped slide bar 6.

[0031] like Figures 1-3As shown, another structure of the locking component is disclosed here. The locking component includes a self-locking motor 8, a gear 9, and a rack 7. The rack 7 is fixedly connected to the side of the arc-shaped slide bar 6. The self-locking motor 8 is fixedly connected to the arc-shaped lower seat 5. The output end of the self-locking motor 8 is fixedly connected to the gear 9. The gear 9 and the rack 7 are meshed together. At this time, by starting the self-locking motor 8, the rack 7 can be rotated through the gear 9, thereby rotating the clamping hand support. After the rotation is completed, the angle of the clamping hand support will be locked by the self-locking motor 8.

[0032] The self-locking motor 8 can be a worm gear motor or a lead screw motor.

[0033] Among them, such as Figures 1-2 As shown, the clamping hand support includes an arc-shaped base plate 10 fixedly connected inside the arc-shaped slide bar 6. Multiple airbag blocks 11 are fixedly connected inside the arc-shaped base plate 10. An air pump is fixedly connected to the arc-shaped base plate 10. The air pump is connected to the multiple airbag blocks 11 through a hose. When the patient's arm is placed inside the arc-shaped base plate 10, the airbag blocks 11 are inflated by starting the air pump until the airbag blocks 11 and the patient's arm are in contact, thus positioning the patient's arm.

[0034] The airbag block 11 can be directly glued to the inner wall of the arc-shaped substrate 10, or a hook and loop fastener 12 can be fixedly connected to the inner wall of the arc-shaped substrate 10, and a hook and loop fastener can be fixedly connected to the outer side of the airbag block 11. The airbag block 11 is glued to the inner wall of the arc-shaped substrate 10 through the hook and loop fastener 12, and the position of the airbag block 11 can be adjusted as needed.

[0035] like Figures 1-2 As shown, a support plate 23 can also be fixedly connected to one side of the arc-shaped lower seat 5, which can support the patient's forearm or elbow.

[0036] like Figures 1-2 As shown, a mounting plate 2 can be fixedly connected to the lower support bracket. The output end of the mounting plate 2 is rotatably connected to a worm gear body 3 and a vertical rotating rod. A worm wheel body 4, which meshes with the worm gear body 3, is fixedly connected to the outer side of the vertical rotating rod. The worm gear body 3 and the worm wheel body 4 are meshed together. The arc-shaped lower seat 5 is fixedly connected to the upper end of the vertical rotating rod. By rotating the worm gear body 3, the worm wheel body 4 can be driven to rotate, thereby driving the arc-shaped lower seat 5 and the clamping hand support and support plate 23 on the arc-shaped lower seat 5 to rotate.

[0037] The lower end of the support bracket can be fixedly connected to a C-shaped frame 13. A threaded rod 14 is threadedly connected to the C-shaped frame 13. A clamping plate 15 is rotatably connected to the end of the threaded rod 14. At this time, the C-shaped frame 13 can be clamped on the operating table through the clamping plate 15 and the upper side wall of the C-shaped frame 13.

[0038] The lower support bracket can be an L-shaped fixed bracket or an adjustable bracket. In this technical solution, an adjustable bracket is preferred, as detailed below. Figure 1 and Figure 4 As shown, the lower support bracket includes a first sleeve 1 fixedly connected to the upper side of the C-shaped frame 13. A first slide rod 16 is vertically slidably connected inside the first sleeve 1. The height of the clamping hand support can be adjusted by vertically sliding the first slide rod 16. A first locking screw 17 is threadedly connected to the upper end of the outer side of the first sleeve 1. The first sliding rod 16 can be locked after adjustment by the first locking screw 17.

[0039] The upper outer side of the first slide rod 16 is rotatably connected to a rotating seat 21. Rotating the rotating seat 21 can drive the clamping hand support to rotate. The rotating seat 21 is threaded with a third locking screw 22. After the rotating seat 21 has rotated, the rotating seat 21 can be locked by the third locking screw 22.

[0040] A second sleeve 18 is fixedly connected to the rotating base 21. A second slide rod 19 is slidably connected inside the second sleeve 18. The end of the second slide rod 19 is fixedly connected to the mounting plate 2. The horizontal position of the clamping hand rest can be adjusted by sliding the second slide rod 19. A second locking screw 20 is threaded on the second sleeve 18. The second slide rod 19 can be locked after sliding by the second locking screw 20.

[0041] Here, a slide bar can be fixedly connected to the inner wall of the second sleeve 18, and a slide groove is provided on the outer side of the second slide rod 19. The slide bar and the slide groove slide together, thereby restricting the rotation of the second slide rod 19 inside the second sleeve 18.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
