[0062] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0063] An embodiment of the present application discloses a surgical arm support device 100, which is fixedly arranged on the side of the operating table to support and fix the patient's arm; it includes: a support member 1, a fixing frame 2, an adjusting block 3, a strap 4, and an adjusting assembly 5; specifically, the support member 1 has a support portion 6 corresponding to the outer contour of the arm; there are two support members 1, corresponding to the patient's forearm and upper arm respectively; the outer contour of the support member 1 is constructed into an arc shape by PVC; the fixing frame is detachably installed on the side of the operating table, and the fixing method can be clamping and fixing by a fixture 7, or sucking and fixing the bottom of the operating table by a suction cup. The fixing method is not an improvement of the solution of the present application, so it will not be described in detail; more specifically, a fixing rod 8 is further arranged on the fixing frame along the first direction L, and the first direction L is the arm extension direction; a connecting sleeve 9 is slidably arranged on the fixing rod 8, and the connecting sleeve 9 is fixedly arranged at the bottom of the support member 1; in this way, the support member 1 can be driven to move along the first direction L, so that the two support members 1 approach / separate from each other to adapt to patients with different body postures.

[0064] Specifically, adjusting blocks 3 are arranged at the two relatively farthest end walls of the two support members 1, and a plurality of the adjusting blocks 3 are arranged evenly along the first direction L; in the initial state, the surface of the adjusting block 3 is flush with the surface of the support portion 6; adjacent two adjusting blocks 3 can move up and down to cause the surfaces for supporting the forearm and the upper arm to deform, so that the different-shaped arms of the patient can be adapted; wherein, a chute 10 is formed on the side wall of the adjusting block 3, and adjacent adjusting blocks 3 are provided with sliders 11 corresponding to the chute 10; the extending direction of the chute 10 is perpendicular to the first extending direction.

[0065] Specifically, the two fixing rods 8 are connected by an adjusting rod 12; wherein, the adjusting rod 12 penetrates the fixing rod 8 in the radial direction so that the fixing rod 8 can be rotatably connected to the adjusting rod 12; with such a setting, the support member for supporting the forearm can rotate along the circumferential direction of the adjusting rod 12 to simulate the bending of the human arm to adapt to the arm support in different states; the adjusting rod 12 and the fixing rod 8 can be automatically limited by friction.

[0066] Specifically, the strap 4 is arranged on the support 1 to fix the patient's arm, and the adjusting assembly 5 is used to adjust the tightness of the strap 4 and the patient's arm; wherein, the adjusting assembly 5 includes: a connecting block 13, a retractor 14, a rotating rod 15, and a limiting structure; specifically, the connecting block 13 is movably arranged on both sides of the support 1 along the first direction L, and the connecting block 13 is used to connect the strap 4 and the support 1, so that the strap 4 spans above the arm; several connecting blocks 13 are arranged and arranged in a line along the first direction L; adjacent two connecting blocks 13 are inserted and arranged to move relative to each other along the first direction L; it can be understood that after the connecting blocks 13 are inserted along the first direction L, they form a telescopic rod; in this way, the distance between adjacent two straps 4 can be adjusted, so that the position of fixing the arm is more selective; specifically, a retractor 14 is rotatably arranged in the connecting block 13 on one side of the support 1, one end of the strap 4 is wound on the retractor 14, and the other end is fixedly connected to the connecting block 13 on the other side of the support 1 without a retractor 14; by rotating the retractor 14, the tightening of the strap 4 can be realized; the rotating rod 15 is rotatably arranged in the connecting connecting block 13; wherein, the retractor 14 is configured as a ring; the rotating rod 15 penetrates through the inner ring 16 of the retractor 14 along the first direction L, and there are gaps between the inner surface of the inner ring 16 and the outer surface of the rotating rod 15; by setting the limiting structure, the retractor 14 can be limited in the circumferential direction of the rotating rod 15;

[0067] More specifically, the limiting structure includes a limiting ball 17 and a limiting part 18; wherein, a part of the surface of the rotating rod 15 is radially concave to form a limiting part 18, and the limiting part 18 is arrayed along the circumferential direction of the rotating rod 15; a groove is formed at a position corresponding to the limiting part 18 on the surface of the inner ring 16 of the retractor 14, and the limiting ball 17 is movably arranged in the groove; specifically, an elastic member 19 is arranged at the bottom of the limiter and the groove, and the elastic member 19 is a spring that always gives an elastic force to the limiting ball 17 to move away from the limiting part 18; in the initial state, 1 / 5 to 1 / 3 of the volume of the limiting ball 17 is located in the limiting part 18; an arc surface / inclined surface is formed on the side of the limiting part 18; through the above design, in the initial state, the limiting ball 17 and the limiting part 18 are limited by friction, so that when the rotating rod 15 is rotated, the retractor 14 is driven to rotate together; when the strap 4 is tightened and the rotating rod 15 is rotated continuously, the strap 4 will not be tightened further, thereby preventing the operator from feeling discomfort when using the strap 4 too tightly;

[0068] A first electromagnet 20 is arranged in the rotating rod 15, and the limiting ball 17 is a metal ball with magnetic conductivity; after the first electromagnet 20 is energized, the generated magnetism can attract the limiting ball 17 to all enter the limiting part 18, so that the retractor 14 is limited in the rotating direction; wherein, a one-way bearing is used to connect the rotating rod 15 and the connecting block 13; for example, the rotating rod 15 can only rotate clockwise, and cannot rotate counterclockwise.

[0069] In another more specific embodiment, the limiting portion 18 extends a partial distance along the first direction L, and the limiting ball 17 can slide a partial distance along the first direction L within the limiting portion 18; in this way, it can adapt to the adjustment of the distance of the connecting block 13 along the first direction L.

[0070] Specifically, a guiding groove 21 is arranged on the surface of the support member 1, and the extending direction of the guiding groove 21 is perpendicular to the first direction L on the surface of the support member 1; wherein, a moving block 22 is slidably arranged in the guiding groove 21, and the moving block 22 is fixedly connected to the connecting block 13 and can drive the entire connecting block 13 to slide along the guiding groove so as to further press the arm; specifically, a second electromagnet 23 is arranged at one end of the guiding groove 21 away from the connecting block 13; wherein, a spring is arranged between the second electromagnet 23 and the moving block 22, and the spring can give an elastic acting force to the moving block 22 to move away from the second electromagnet 23, and can reset after the second electromagnet 23 loses magnetism; after the second electromagnet 23 generates magnetism, it can attract the first electromagnet 20; it can be understood that when bleeding occurs in the arm during the operation process, starting the second electromagnet 23 can quickly tighten the strap 4, and it can be understood that it can quickly perform compression hemostasis.

[0071] In another more specific embodiment, a support pad 23 is covered on the surface of the support portion 6, and the support pad 23 is made of silica gel; through the design of the support pad 23, a comfortable flexible support touch can be provided to the patient, improving the comfort; specifically, fixing strips 24 are arranged on both sides of the support member 1, the fixing strips 24 extend along the first direction L, and are filled with magnetorheological fluid inside; wherein, a third electromagnet 25 is arranged in the fixing strip 24, and the third electromagnet 25 can generate magnetism after being energized, and when energized, it will change the state of the magnetorheological fluid, changing the magnetorheological fluid from a Newtonian fluid with low viscosity to a Bingham fluid with high viscosity and low fluidity, and there is a corresponding relationship between the viscosity of the magnetorheological fluid and the magnetic flux;

[0072] Through the above design, after the adjusting block 3 moves and fits the arm, the fixing strip 24 will also deform; then after the third electromagnet 25 is energized, the adjusting block 3 is always kept in the deformed state;

[0073] In addition, the second electromagnet 23 is repeatedly energized and de-energized, and by controlling the current flow, the magnetism of the second electromagnet 23 can be adjusted to control the moving distance of the connecting block 13; it can be understood that the intermittent tightening of the strap 4 combined with the softness of the support pad 23 plays a role in massaging the arm.

[0074] In another embodiment, the strap 4 contains a heat-conducting agent, and the heat-conducting agent can be water, physiological saline; a semiconductor refrigerating sheet is installed on the support member 1; through the above settings, while being able to perform compression hemostasis, the temperature of the heat-conducting agent can be reduced, so as to assist in hemostasis;

[0075] A heat-conducting wire electrically connected to the semiconductor refrigerating sheet is arranged inside the support pad 23, which can adjust the temperature of the support pad 23 to make the patient more comfortable. In addition, an electronic temperature sensor is further arranged on the support part 6, and the electronic temperature sensor is electrically connected to the semiconductor refrigerating sheet, so that the temperature of the support pad 23 can be adjusted according to the body temperature of the patient's arm.
