DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0028] Example:

[0029] See also Figure 1 and Figure 2 In this embodiment, an adjustable intraoperative arm posture holder is provided, which is specifically used to provide a stable and adjustable arm support platform to adapt to the arm sizes of different patients and the different arm fixing positions that may be required during the operation. It specifically includes: a base 11, which is stably mounted on one side of the operating bed 15 and is tightly combined with the armrest 16 of the operating bed 15 to ensure the stability and reliability of the entire holder during the operation.

[0030] The support column 12 is rotatably connected to the upper portion of the base 11 and is equipped with a first driving component 2 for driving the support column 12 to swing in the horizontal direction;

[0031] The support arm 13 is slidably connected to the support column 12, and the support column 12 is provided with a second driving component 3 for driving the support arm 13 to slide in the vertical direction;

[0032] an arm bracket 14 rotatably and fixedly connected to the end of the support arm 13 for supporting the patient's arm;

[0033] The support arm 13 is a telescopic structure, and the axial position of the arm bracket 14 relative to the support arm 13 can be adjusted.

[0034] Specifically, in this embodiment, after the base 11 is installed, the support column 12 can be flexibly rotated in the horizontal direction through the drive of the first drive component 2, and can drive the support arm 13 to swing horizontally to adapt to the need to adjust the lateral position of the arm during surgery. In addition, the support arm 13 is driven by the second drive component 3 to achieve sliding in the vertical direction, fixing the patient's arm on the arm bracket 14. Since the support arm 13 adopts a retractable structure and its length is adjustable, the distance between the arm bracket 14 and the base 11 in the fixed position is adjustable, meeting the need to adjust the distance from the patient's arm when the base 11 is fixedly installed on the armrest 16 of the operating table 15 (it can also be installed on other horizontally arranged rods according to actual needs). In addition, the arm bracket 14 is rotatably connected to the end of the support arm 13, and its angle is adjustable so that it is set obliquely downward toward the patient. After the angle of the arm bracket 14 is fixed, the patient's arm is unfolded and lifted so that his arm can naturally rest on the arm bracket 14, and then the patient's arm is supported and maintained fixed in a specific position to facilitate incision operations in the armpit area. The above-mentioned adjustments can also be performed during the operation of the utility model to meet actual usage needs.

[0035] See also Figure 3 In this embodiment, the first drive component 2 is a steering gear 21, which is connected to a turntable 22. The housing of the steering gear 21 is fixedly connected to the base 11, and the turntable 22 is fixedly connected to the support column 12. The second drive component 3 is a linear drive module, which includes a screw motor 31. The screw shaft of the screw motor 31 is threadedly connected to a slider 32. The slider 32 is provided with guide protrusions 33 on both sides. The support column 12 is provided with a guide groove 34 that slidably fits the guide protrusions 33. The slider 32 is fixedly connected to the support arm 13.

[0036] See also Figure 4The base 11 includes a support plate 41 with a guide groove at its bottom, which is slidably connected to a pressure plate 42. Side plates 43 are provided at both ends of the support plate 41. Each side plate 43 is threadedly connected to a clamping component 5 that drives the pressure plate 42 toward the other side plate 43. The armrest 16 of the operating table 15 is clamped between the side plates 43 and the pressure plate 42 to install the base 11. The side plates 43 have a first threaded hole 44. The clamping component 5 includes a first stud 51 that is threadedly connected to the first threaded hole 44. One end of the first stud 51 is in close contact with the side of the pressure plate 42, and the other end is fixedly connected to a clamping knob 52 that drives it to rotate relative to the side plate 43. Rotating the clamping knob 52 causes the first stud 51 to move the pressure plate 42 toward the other side plate 43, thereby tightly clamping the armrest 16 of the operating table 15 between the side plates 43 and the pressure plate 42. To further enhance the stability of the device, an anti-skid pad is provided at the bottom of the base 11 in this embodiment. The anti-skid pad is made of a high-friction material and can effectively prevent the base 11 from sliding due to vibration or external force during surgery, thereby enhancing the safety of the device.

[0037] See also Figure 5 The support arm 13 includes a fixed sleeve 61, in which a support shaft 62 is slidably and rotatably connected. The end of the support shaft 62 is connected and fixed to the arm bracket 14. The fixed sleeve 61 is provided with a locking component 7 for locking the support shaft 62. The fixed sleeve 61 is provided with a second threaded hole 63, and the locking component 7 includes a second stud 71 threadedly connected and adapted to the second threaded hole 63. One end of the second stud 71 is provided with a locking knob 72 for driving the rotation thereof. When it is necessary to adjust the length of the support arm 13 or the angle of the arm bracket 14, the locking knob 72 is loosened. At this time, the support shaft 62 is temporarily disengaged from the fixed sleeve 61, and it can rotate or slide relative to the fixed sleeve 61. When the position adjustment of the arm bracket 14 is completed, the locking knob 72 is tightened to achieve the locking between the support shaft 62 and the fixed sleeve 61.

[0038] See also Figure 6 The arm support 14 includes a frame 81 connected and fixed to the support shaft 62. Several groups of pads 82 for supporting the arm are arranged in the frame 81 to provide multi-point support for the patient's arm, evenly disperse the pressure, prevent the arm from being locally over-pressurized during a long operation, and reduce the patient's discomfort. The pads 82 are made of a soft and elastic material, which further improves the comfort and stability of the support. A fixing belt 83 for restraining the arm is also provided on the frame 81 to prevent the arm from sliding or shifting during the operation. The fixing belt 83 adopts an adjustable length design, which is suitable for patients of different body shapes, and is quickly fixed and released by Velcro or buckles, which is convenient and quick to operate.

[0039] The surface of the pad 82 is provided with an arc-shaped profile 84 that fits the arm. The arc-shaped profile 84 better disperses the pressure on the arm and reduces the discomfort and damage caused by excessive local pressure during long-term surgery. The frame 81 in this embodiment is made of hard plastic or alloy material, and airbags 85 are also provided at both ends of the frame 81 to avoid direct contact between the patient's arm and the end of the frame 81, causing pressure to affect the blood circulation in the arm area.

[0040] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
