Description

Technical Field

[0001] This utility model relates to the field of medical technology, and more specifically, it relates to a multi-segment adjustable anti-damage handrest. Background Technology

[0002] A hand rest is a support plate used to stabilize the patient's arm during surgery. Whether the patient is supine, prone, lithotomy, or lateral decubitus, a hand rest is necessary to immobilize the arm. For longer surgeries, prolonged non-physiological flexion-extension positions or single-point pressure on the limbs under various positions can cause nerve or joint-related damage.

[0003] Therefore, it is necessary to provide a multi-segment adjustable anti-damage handrest to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a multi-segment adjustable anti-injury handrest to adapt to the patient's position.

[0005] The technical solution adopted by this application to solve its technical problem is: a multi-segment adjustable anti-damage handrest, including a sleeve, in which several handrests are fixedly installed, and several connecting structures are provided between two adjacent handrests. The connecting structure includes a first rotating plate and a second rotating plate. The upper side of the first rotating plate and the second rotating plate are respectively fixed to a handrest. The first rotating plate and the second rotating plate are rotatably connected. A support shaft is fixed on one side of the first rotating plate. A limit rod is rotatably connected to the support shaft. A limit shaft is fixed on one side of the second rotating plate. Several limit grooves adapted to the limit shaft are provided on one side of the limit rod. The limit shaft is inserted into a limit groove. A limit elastic element is connected between the end of the limit rod away from the support shaft and the second rotating plate.

[0006] Furthermore, the bottom of the plate sleeve is provided with several clearance grooves corresponding to the positions of the connecting structures.

[0007] Furthermore, safety belts are fixedly installed at both ends of the plate sleeve.

[0008] Furthermore, a reset elastic element is connected between the first rotating plate and the second rotating plate.

[0009] The beneficial effects of this utility model are:

[0010] By adjusting the angle between the handrests, the posture can be adjusted more precisely and accurately to conform to the physiological angle of the human body according to different body positions, which is more conducive to infusion management and can make the surgical position more ideal, thereby minimizing the discomfort symptoms caused by changes in body position due to surgical position and infusion management after surgery.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] like Figure 1-3 As shown, this application provides a multi-segment adjustable anti-damage handrest, including a board sleeve 1. Safety belts 11 are fixedly installed at both ends of the board sleeve 1. Several handrests 12 are fixedly installed inside the board sleeve 1. Several connecting structures 2 are provided between two adjacent handrests 12. Several clearance grooves 13 corresponding to the positions of the connecting structures 2 are provided at the bottom of the board sleeve 1.

[0022] The connecting structure 2 includes a first rotating plate 21 and a second rotating plate 22. The upper sides of the first rotating plate 21 and the second rotating plate 22 are respectively fixed to a handrest plate 12, and the first rotating plate 21 and the second rotating plate 22 are rotatably connected.

[0023] A reset elastic element 23 is connected between the first rotating plate 21 and the second rotating plate 22.

[0024] A support shaft 24 is fixed on one side of the first rotating plate 21, and a limit rod 25 is rotatably connected to the support shaft 24. A limit shaft 26 is fixed on one side of the second rotating plate 22, and a number of limit grooves 27 adapted to the limit shaft 26 are provided on one side of the limit rod 25. The limit shaft 26 is inserted into one of the limit grooves 27.

[0025] A limiting elastic element 28 is connected between the end of the limiting rod 25 away from the support shaft 24 and the second rotating plate 22.

[0026] In this embodiment, both the reset elastic element 23 and the limiting elastic element 28 are tension springs.

[0027] The safety belt 11 is used to secure the patient's arm, fixing the arm to the armrest 12.

[0028] Typically, this type of multi-segment adjustable anti-damage handrest is like... Figure 1 As shown, the handrest plates 12 are assembled into a straight plate, at which point both the reset elastic element 23 and the limiting elastic element 28 are in a stretched state. The reset elastic element 23 causes the first rotating plate 21 and the second rotating plate 22 to tend to move closer together. This tendency will cause the support shaft 24 and the limiting shaft 26 to tend to move closer together, while the limiting elastic element 28 will pull the limiting rod 25 away from the end of the support shaft 24, causing a limiting groove 27 on the limiting rod 25 to lock the limiting shaft 26. The limiting groove 27 will prevent the support shaft 24 and the limiting shaft 26 from moving closer together by locking the limiting shaft 26. At the same time, in conjunction with the obstruction when the two handrest plates 12 are in direct contact, both will prevent the first rotating plate 21 and the second rotating plate 22 from moving closer together, thereby keeping the two handrest plates 12 in a parallel state.

[0029] When it is necessary to adjust the angle between the two handrests 12, simply grasp both handrests 12 and rotate them. At this time, the support shaft 24 and the limiting shaft 26 begin to move away from each other. The limiting groove 27 cannot prevent this movement, which will cause the limiting rod 25 to overcome the elastic force of the limiting elastic element 28 and rotate around the support shaft 24, causing the limiting shaft 26 to disengage from the limiting groove 27. That is, the limiting rod 25 does not prevent the angle between the two handrests 12 from widening. The user can freely overcome the elastic force of the reset elastic element 23 and the limiting elastic element 28 to widen the angle between the two handrests 12.

[0030] When the limiting elastic element 28 causes the limiting shaft 26 to disengage from one limiting groove 27, the adjacent limiting groove 27 will promptly engage. This completes the angle widening between the two handrests 12. When the user releases their grip, the elastic force of the reset elastic element 23 causes the first rotating plate 21 and the second rotating plate 22 to tend to move closer together. The nearest limiting groove 27 will then promptly engage the limiting shaft 26, preventing the angle between the two handrests 12 from resetting and maintaining the two handrests 12 at the adjusted angle.

[0031] After the surgery is completed, the user can pull the limiting rod 25 to separate the limiting groove 27 and the limiting shaft 26. The elastic force of the reset elastic element 23 will cause the first rotating plate 21 and the second rotating plate 22 to move closer to each other until the two hand rests 12 come into contact. At this time, the reset between the two hand rests 12 is completed, and the user can release the limiting rod 25.

[0032] In summary, this design achieves the effect of conveniently adjusting the angle between the 12 handrests, allowing for more precise and accurate adjustment of the posture to conform to the physiological angle of the human body according to different body positions. This facilitates infusion management, enabling the surgical position to reach a more ideal state, thereby minimizing the discomfort symptoms caused by changes in body position due to surgical positioning and infusion management needs after surgery.
