[0031] Referring to Figs. 1 to 3 as shown;

[0032] The present embodiment discloses an adjusting and fixing support for an upper limb of an operation side, comprising:

[0033] The first support 1 and the second support 2 are rotatably connected to match the synchronous rotation of the bending action between the upper arm part and the lower arm part of the surgical upper limb, that is, the rotatable connection part rotates in the plane of the first support 1 and the second support 2 to rotate with the flexion and extension action of the upper arm part and the lower arm part, so that the upper limb can be slightly flexed when supporting the surgical upper limb, and the upper limb is better in a relaxed state. The first support 1 is used to support the upper arm part of the surgical upper limb, and the second support 2 is used to support the lower arm part of the surgical upper limb. The first support 1 is an open frame structure, and a plurality of movable bearing plates 11 are arranged on the inner side of the first support 1 to support the upper arm part. The movable bearing plates 11 match the use of different arm lengths by adjusting the distance between the movable bearing plates 11 and the rotatable connection part on the first support 1, that is, the arm and the body of the person with shorter arm length are closer to the second support 2 position, so that the upper limb is completely and matched placed on the support, and the upper limb joint part is correspondingly placed between the rotatable connection part of the first support 1 and the second support 2. The second support 2 is a closed frame structure, and a plurality of fixed bearing plates 21 are arranged on the inner side of the second support 2 to support the lower arm part, and the length is sufficient to support different arm length users without length adjustment;

[0034] The main support frame 3 is vertically arranged, and the swing support frame 4 is arranged on the upper end of the main support frame 3. The middle position of the swing support frame 4 is rotatably connected to the upper end of the main support frame 3. The upper end of the swing support frame 4 is rotatably connected to the first support 1. The connection part between the upper end of the swing support frame 4 and the first support 1 is arranged close to the second support 2. Therefore, the first support 1 position mainly bears the weight of the upper limb, so that the swing support frame 4 is supported at this position, and the support height of the first support 1 is adjusted by adjusting the inclination angle of the swing support frame 4. The rotatable connection form between the first support 1 and the swing support frame 4 can match the inclination angle of the first support 1 when the surgical upper limb is raised, so as to better support the surgical upper limb; and

[0035] The swing driving mechanism is arranged on the main support frame 3 to drive the swing of the swing support frame 4. The adjustment is convenient, and the support adjustment of the swing support frame 4 is more convenient and fast.

[0036] Further, the movable bearing plate 11 and the inner side of the first support 1 are provided with a moving adjustment structure to support the movement of the movable bearing plate 11 in the inner side of the first support 1, so as to match the use of different arm length people.

[0037] Further, the mobile adjusting structure comprises: guide grooves 111 opened on the opposite side surfaces of the inner side of the first support 1, and sliding blocks 112 arranged in the guide grooves 111 and sliding in the guide grooves 111, and each of the two ends of each movable bearing plate 11 is connected to the sliding block 112.

[0038] Further, the number of the sliding blocks 112 in each side guide groove 111 corresponds to the number of the movable bearing plates 11.

[0039] Specifically, among the plurality of movable bearing plates 11, the one farthest from the rotatable connecting part between the first support 1 and the second support 2, or the second support 2, is moved to a distance from the second support 2 matching the length of the upper arm in the upper limb, so as to be completely supported below the upper arm, and the upper limb joint part is just located at the rotatable connecting part between the first support 1 and the second support 2. During the adjustment, the movement of the movable bearing plate 11 is adjusted by the sliding blocks 112 at both ends sliding in the respective guide grooves 111. Therefore, in order to better cope with users with shorter arms, the width of the first support 1, that is, the inner width, can accommodate one side of the body to enter, so that the joints of the shorter length arm can reach the rotatable connecting part between the first support 1 and the second support 2.

[0040] Further, the upper surfaces of the first support 1 and the second support 2 are provided with a bandage 5 for binding the surgical side upper limb, the bandage 5 comprises two left-right symmetrical bands connected by a magic tape to be bound to the surgical side upper limb position, and the bandage 5 is bound to the arm to fix the surgical side upper limb on the first support 1 and the second support 2, so as to make the support of the upper limb more stable, and the tightness is adjusted by the length of the magic tape pasting position.

[0041] Further, the lower end of the main support frame 3 is provided with a support base 31, which is the main support structure of the support, and the lower surface of the support base 31 is provided with a moving wheel 32 for more convenient movement of the support to the appropriate position for use.

[0042] Further, the swing driving mechanism comprises: a threaded rod 33 vertically arranged on one side of the main support frame 3, the threaded rod 33 being rotatably supported by a bearing arranged on one side of the main support frame 3, the upper end of the threaded rod 33 extending upward through the swing support frame 4 and being arranged above the swing support frame 4, a rotating driving handle 34 being arranged on the upper end of the threaded rod 33, a nut pair 35 being arranged on the threaded rod 33 and threadedly matched with the threaded rod 33, a transmission rod 36 being arranged between the nut pair 35 and the end of the swing support frame 4 opposite to the first support 1, and the two ends of the transmission rod 36 being hingedly connected with the nut pair 35 and the swing support frame 4.

[0043] Specifically, in the process of adjusting the inclination angle of the swing support frame 4 to adjust the support height of the first support 1, the rotating drive handle 34 is manually operated to drive the threaded rod 33 to rotate, and the nut pair 35 threaded with the threaded rod 33 is unable to rotate due to the connection between the nut pair 35 and the swing support frame 4 through the transmission rod 36, and can move axially along the threaded rod 33, and in the moving process, the swing support frame 4 is supported on the end of the first support 1 in the opposite direction through the transmission rod 36, so as to realize the function of adjusting the support angle of the swing support frame 4.

[0044] Further, the arc-shaped plates 12 extending outward on both sides of the open end of the first support 1 gradually expand the opening width, so that the upper limbs with different arm lengths can be placed on the first support 1 and the second support 2 conveniently, accurately and safely, especially for users with shorter arm lengths. In addition, it should be determined that the support is suitable for patients who sit or lie down, because it is more difficult for the patient to raise the upper limb on the surgical side when sitting or lying down than when lying completely.

[0045] In the above technical solution, the adjusting and fixing support for the upper limb on the surgical side has the following beneficial effects:

[0046] The first support and the second support of the present application can match and support according to the raised state of the upper limb on the surgical side, and can accurately match according to the inclination angle when the arm is raised, the small amplitude flexion state of the arm, and the arm length of the patient, so as to realize reasonable support and better realize the fixed support of the upper limb on the surgical side.

[0047] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
