Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an intraoperative adjustable tilt angle arm support. Background Technology

[0002] Intraoperative support frames are known to be important auxiliary tools in the field of medical devices. They are mainly used to provide doctors with a stable operating platform during surgery, or to provide support for patients' limbs and organs, thereby improving surgical precision, reducing doctor fatigue, and optimizing patient positioning. Their applications cover a variety of complex procedures such as interventional surgery, orthopedic surgery, and vascular surgery. In particular, if the patient has intravenous access in their arm during surgery, in order to facilitate observation of the venipuncture site, observe for the occurrence of intravenous infusion complications, and ensure the patency of the access, it is necessary to expose the intravenous access for intraoperative drug administration. Therefore, the conventional method is to use an extension tube.

[0003] However, in actual use, if an extension tube is used, the drug administration will be delayed, which will affect the drug administration speed; if the existing support frame is used to place the arm, it will occupy the operating space and affect the doctor's operation. Therefore, an arm support frame with an adjustable tilt angle during operation is proposed as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an intraoperative adjustable tilt angle arm support to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intraoperative adjustable tilt arm support frame, comprising: a first support plate and a second support plate for supporting the patient's arm, one end of the first support plate being connected to one end of the second support plate via a tilt adjustment mechanism, the bottom of the first support plate being rotatably connected to a base via a pivot, the base being connected to the hospital bed via a snap fastener, and a snap-fit ​​mechanism being provided between the bottom of the first support plate and the base.

[0006] Furthermore, the tilting mechanism includes: a fixed seat, a connecting seat, an L-shaped pull rod pawl, and a compression return spring;

[0007] The fixed seat and the connecting seat are respectively fixedly installed at one end of the first support plate and the second support plate. The two connecting seats are rotatably connected to the fixed seat through a rotating shaft. The second support plate is fixedly connected to the L-shaped pull rod pawl through a compression return spring. The L-shaped pull rod pawl is engaged with the fixed seat.

[0008] Furthermore, the interior of the second support plate is provided with a T-shaped telescopic groove for sliding of the L-shaped tie rod pawl, and the surface of the fixed seat is provided with a number of uniformly distributed arc-shaped fixing grooves along the rotation direction of the connecting seat.

[0009] The L-shaped pull rod pawl includes: a pull handle and a telescopic pawl, wherein one end of the pull handle is fixedly connected to one end of the telescopic pawl;

[0010] The inner wall of the T-shaped telescopic groove is fixedly connected to one end of the telescopic pawl by a compression reset spring, and the other end of the telescopic pawl passes through the T-shaped telescopic groove and engages with the fixed groove.

[0011] The other end of the pull handle has a T-shaped telescopic groove.

[0012] Furthermore, a baffle for limiting the rotation angle of the second support plate is fixedly connected to the bottom of the fixed base, and the baffle abuts against the bottom of the second support plate.

[0013] Furthermore, the locking mechanism includes: a telescopic rod, a limiting block, a pull ring, and a tension return spring;

[0014] The top of the limiting block is fixedly installed on the bottom of the first support plate. A limiting groove is opened inside the limiting block. The telescopic rod passes through the limiting groove and is slidably connected to the limiting groove. Several circularly evenly distributed fixing slots are opened on the surface of the base along the rotation direction of the first support plate. One end of the telescopic rod is engaged with the fixing slot, and a pull ring is fixedly installed on the other end of the telescopic rod. The tension return spring is movably sleeved on the surface of the telescopic rod, and the pull ring is fixedly connected to the limiting block through the tension return spring.

[0015] Furthermore, the upper surfaces of both the first and second support plates are covered with soft pads for supporting the patient's limbs.

[0016] Furthermore, the included angle between the first support plate and the second support plate is set in the range of 90-180°.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] Compared to existing technologies, by incorporating a snap-fit ​​mechanism, the snap-fit ​​fixation with the base can be controlled, thus allowing control of the angle between the first support plate and the bed. The second support plate moves with the first support plate, providing arm support for the patient at the bedside. The tilt-adjusting mechanism changes the angle between the first and second support plates, allowing the patient to raise their arm. This supported arm not only facilitates observation of the venipuncture site by medical staff to monitor for intravenous infusion complications and ensure patency of the access, but also allows for intraoperative drug administration without extension tubes, eliminating drug administration delays and simplifying the process. Because it is fixed at the bedside, no additional support frame is needed, thus not interfering with the surgeon's work. Furthermore, the tilted second support plate maintains the normal physiological curvature of the patient's arm, ensuring patient comfort. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] As attached Figure 1-4 The illustrated intraoperative adjustable tilt arm support includes: a first support plate 1 and a second support plate 2 for supporting the patient's arm.

[0037] The first support plate 1 can be used to support the patient's shoulder or elbow joint, while the second support plate 2 is used to support the arm, so that the arm has support at a certain height.

[0038] One end of the first support plate 1 is connected to one end of the second support plate 2 via an adjustment mechanism 3. The bottom of the first support plate 1 is rotatably connected to a base 4 via a pivot, and the base 4 is connected to the hospital bed via a buckle 5.

[0039] The base 4 is connected to the side of the hospital bed via a buckle 5. This conventional buckle can be opened and closed by a handle, and thus the buckle can be clamped onto the fixing strip reserved on the side of the hospital bed.

[0040] A snap-fit ​​mechanism 6 is provided between the bottom of the first support plate 1 and the base 4.

[0041] Since the first support plate 1 is rotatably connected to the base 4, and the snap-fit ​​mechanism 6 can control the snap-fit ​​fixation of the first support plate 1 and the base 4, it can control the angle between the first support plate 1 and the hospital bed. The second support plate 2 moves with the first support plate 1, so the first support plate 1 and the second support plate 2 can provide the patient with a support arm at the side of the hospital bed.

[0042] The tilting mechanism 3 can change the angle between the first support plate 1 and the second support plate 2, so that the patient can raise his arm. The raised arm is supported, which not only makes it easier for medical staff to observe the venipuncture site, but also allows for intraoperative drug administration without the need for extension tubes, thus eliminating drug administration delays and making drug administration convenient. Since it is fixed to the bedside, no additional support frame is needed, and it does not affect the doctor's operation. At the same time, the tilted second support plate 2 also ensures the normal physiological curvature of the patient's arm, ensuring the patient's comfort.

[0043] In a preferred embodiment, as shown in the appendix Figure 1 and attached Figure 3 As shown, the tilting mechanism 3 includes: a fixed base 31, a connecting base 32, an L-shaped pull rod pawl 33, and a compression return spring 34;

[0044] The fixed seat 31 and the connecting seat 32 are respectively fixedly installed at one end of the first support plate 1 and the second support plate 2. The two connecting seats 32 are rotatably connected to the fixed seat 31 through a rotating shaft. The second support plate 2 is fixedly connected to the L-shaped pull rod pawl 33 through a compression return spring 34. The L-shaped pull rod pawl 33 is engaged with the fixed seat 31.

[0045] When medical staff pull the L-shaped pull rod pawl 33, it will apply pressure to the compression return spring 34 and the L-shaped pull rod pawl 33 will disengage from the fixed seat 31. The second support plate 2 can rotate around the center line of the fixed seat 31 and the connecting seat 32. At this time, medical staff can lift the second support plate 2 to make it gradually tilt. As the tilt angle increases, the angle formed between the second support plate 2 and the first support plate 1 gradually decreases, thereby adjusting the tilt angle of the patient's arm.

[0046] When medical staff release the L-shaped pull rod pawl 33, the reset compression spring 34 will re-engage the L-shaped pull rod pawl 33 with the fixed seat 31. At this time, the first support plate 1 supports the second support plate 2, and the included angle between the two is fixed, so the second support plate 2 cannot rotate.

[0047] In a preferred embodiment, as shown in the appendix Figure 3 As shown, the interior of the second support plate 2 is provided with a T-shaped telescopic groove 21 for sliding of the L-shaped tie rod pawl 33, and the surface of the fixed seat 31 is provided with a number of arc-shaped and evenly distributed fixing grooves 311 along the rotation direction of the connecting seat 32.

[0048] The position of the fixing groove 311 can determine the included angle between the first support plate 1 and the second support plate 2;

[0049] The L-shaped lever pawl 33 includes: a pull handle 331 and a telescopic pawl 332, with one end of the pull handle 331 fixedly connected to one end of the telescopic pawl 332;

[0050] The inner wall of the T-shaped telescopic groove 21 is fixedly connected to one end of the telescopic pawl 332 by the compression return spring 34, and the other end of the telescopic pawl 332 passes through the T-shaped telescopic groove 21 and is engaged with the fixed groove 311.

[0051] Among them, medical staff control the movement of the pull handle 331 to control the telescopic pawl 332 to move within the T-shaped telescopic groove 21; thereby controlling the telescopic pawl 332 to engage with the fixed groove 311.

[0052] The other end of the pull handle 331 has a T-shaped telescopic groove 21 for easy gripping by medical staff.

[0053] In a preferred embodiment, as shown in the appendix Figure 2As shown, a baffle 7 for limiting the rotation angle of the second support plate 2 is fixedly connected to the bottom of the fixed base 31, and the baffle 7 abuts against the bottom of the second support plate 2 so as to prevent the included angle between the second support plate 2 and the first support plate 1 from exceeding 180°, and ensure that the second support plate 2 plays the role of supporting the arm.

[0054] In a preferred embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, the locking mechanism 6 includes: a telescopic rod 61, a limiting block 62, a pull ring 63, and a tension return spring 64;

[0055] The top of the limiting block 62 is fixedly installed at the bottom of the first support plate 1. A limiting groove 621 is opened inside the limiting block 62. The telescopic rod 61 passes through the limiting groove 621 and is slidably connected to the limiting groove 621. Several circularly evenly distributed fixing slots 41 are opened on the surface of the base 4 along the rotation direction of the first support plate 1. One end of the telescopic rod 61 is engaged with the fixing slot 41. A pull ring 63 is fixedly installed on the other end of the telescopic rod 61. A tension return spring 64 is movably sleeved on the surface of the telescopic rod 61. The pull ring 63 is fixedly connected to the limiting block 62 through the tension return spring 64.

[0056] In this system, the telescopic rod 61 is restricted by the limiting block 62 to move telescopically at the bottom of the first support plate 1. When the telescopic rod 61 is engaged with the fixing slot 41 of the base 4, the first support plate 1 and the base 4 will not rotate. When medical staff overcome the elastic force of the tension return spring 64 by pulling the pull ring 63 and pull the telescopic rod 61 to disengage from the fixing slot 41, the first support plate 1 and the base 4 can rotate, thereby changing the angle between the first support plate 1 and the hospital bed.

[0057] The pull ring 63 can be circular in shape to facilitate pulling the telescopic rod 61.

[0058] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 4 As shown, the upper surfaces of the first support plate 1 and the second support plate 2 are both covered with soft pads 8 for supporting the patient's limbs, so as to provide support and protection for the patient's arm and improve the patient's comfort.

[0059] In a preferred embodiment, as shown in the appendix Figure 1-4 As shown, the included angle between the first support plate 1 and the second support plate 2 is set in the range of 90-180°, so that the second support plate 2 can support the patient's arm at a certain height and prevent the patient's arm from slipping.

[0060] Working principle of this utility model:

[0061] When in use, if support for the patient's arm is required, medical staff first use buckle 5 to fix the base 4 to the side of the bed; then use pull ring 63 to overcome the elasticity of tension return spring 64 and pull telescopic rod 61 to disengage from the fixed slot 41. At this time, the first support plate 1 and the base 4 can rotate, thereby adjusting the angle between the first support plate 1 and the second support plate 2 and the bed; then release the telescopic rod 61, and the reset tension return spring 64 makes the telescopic rod 61 re-engage with the fixed slot 41, at which point the angle between the first support plate 1 and the second support plate 2 and the bed is fixed.

[0062] If it is necessary to raise the patient's arm, the medical staff pulls the L-shaped pull rod pawl 33 to apply pressure to the compression return spring 34, and the L-shaped pull rod pawl 33 disengages from the fixed seat 31. The second support plate 2 can then rotate around the center line of the fixed seat 31 and the connecting seat 32. At this time, the medical staff can raise the second support plate 2 to gradually tilt it. As the tilt angle increases, the angle between the second support plate 2 and the first support plate 1 gradually decreases, thereby raising the second support plate 2 to support the patient's arm and adjusting the tilt angle of the patient's arm. When the L-shaped pull rod pawl 33 is released, the reset compression return spring 34 re-engages the L-shaped pull rod pawl 33 with the fixed seat 31. At this time, the first support plate 1 supports the second support plate 2, and the angle between them is fixed, preventing the second support plate 2 from rotating.
