[0002] Clinically, upper limb traction refers to using the antagonism of body strength to exercise the muscles of the patient's shoulder, wrist and fingers to enhance the flexibility of the muscles and ligaments of the corresponding parts, and it is a treatment scheme for recovering the functional disorders and injuries of the patient's finger joints. At present, the doctor mainly holds the patient's affected limb to perform artificial traction. This scheme consumes the doctor's manpower, and the inaccurate holding in the operation process can easily slip and cause secondary injury. Therefore, how to develop a new upper limb traction scheme to overcome the above problems in the prior art is the direction that the person skilled in the art needs to study. SUMMARY

[0003] The utility model discloses a kind of upper limb traction devices, without doctor intervention can realize the independent traction training of patient affected limb, reduce the workload of doctor, and reduce the secondary injury caused by the inaccuracy of holding.

[0005] Upper limb connecting portion, the upper limb connecting portion is distributed with a plurality of clamping blocks for clamping fingers;

[0006] Traction rope, one end of the traction rope is fixedly installed with the upper limb connecting portion as a whole;

[0007] Stand, the stand extends along vertical direction, and its bottom is connected with stand base;The other end of the traction rope is installed on the column body of the stand.

[0008] By adopting this technical scheme: first, the finger clamping block distributed on the upper limb connecting portion is used to clamp the fingers on the patient's affected limb, and then the patient can perform independent traction training relative to the stand using the traction rope. Thus, without doctor intervention. At the same time, since the clamping of the fingers is completed by a mechanical structure, the problem of slipping and causing secondary injury during traction training is reduced.

[0009] Preferably, the upper limb connecting portion includes: a circular arc base plate, a traction connecting plate, a first straight plate, a second straight plate, a first arc plate and a second arc plate;

The number of the mounting holes is configured to be several and arranged in a straight line in the vertical direction.

[0022] By adopting the technical scheme, the sleeve is moved along the stand according to the height of the patient until the threaded hole is aligned with a certain mounting hole, and the locking bolt is rotated to enter the mounting hole, so that the relative position of the sleeve on the stand is fixed.

[0023] In practice, the number of the threaded hole and the locking bolt can be two or more. In order to facilitate the alignment of the threaded hole and the mounting hole, a scale mark line corresponding to the mounting hole can be arranged on the stand according to the relative position of the sleeve and the threaded hole.

The outer edge of the plate body of the circular-arc base plate 110 is also symmetrically provided with a first positioning block 171 and a second positioning block 172.

[0037] The fifth clamping block 165 is also installed on the circular-arc base plate 110; the first sliding block 151 is slidably installed in the first arc groove 111, and the first clamping block 161 is installed on the first sliding block 151; the second sliding block 152 is slidably installed in the second arc groove 112, and the second clamping block 162 is installed on the second sliding block 152; the third sliding block 153 is slidably installed in the third arc groove 113, and the third clamping block 163 is installed on the third sliding block 153; the fourth sliding block 154 is slidably installed in the fourth arc groove 114, and the fourth clamping block 164 is installed on the fourth sliding block 154; the fifth clamping block 165 is located between the second arc groove 112 and the third arc groove 113.

[0038] One end of the plate body of the first straight plate 131 is rotatably connected to the first positioning block 171, the middle segment of the plate body is fixedly connected to the first sliding block 151, and the other end of the plate body is rotatably connected to one end of the plate body of the first arc plate 141; one end of the plate body of the second straight plate 132 is rotatably connected to the second positioning block 172, the middle segment of the plate body is fixedly connected to the fourth sliding block 154, and the other end of the plate body is rotatably connected to one end of the plate body of the second arc plate 142; the traction connecting plate 120 is in a triangular shape, the other end of the plate body of the first arc plate 141 and the other end of the plate body of the second arc plate 142 are rotatably connected to two corners of the traction connecting plate 120, respectively; one end of the traction rope 200 is connected to the third corner of the traction connecting plate 120.

[0039] In the example: the first clamp block 161, the second clamp block 162, the third clamp block 163, the fourth clamp block 164 and the fifth clamp block 165 are isosceles triangle clamp blocks respectively; and the first clamp block 161, the second clamp block 162, the third clamp block 163, the fourth clamp block 164 and the fifth clamp block 165 are made of elastic materials such as rubber respectively.

[0040] The stand 300 extends in the vertical direction, and a stand base 310 is fixedly installed at the bottom of the stand 300. The stand base 310 is configured to greatly reduce the overall gravity center of the stand 300. A sleeve 320 is sleeved on the column body of the stand 300. The surface of the sleeve 320 is provided with a buckle ring 330 and a threaded hole 340. The other end of the traction rope 200 is installed on the buckle ring 330. A locking bolt 350 is rotatably connected to the threaded hole 340. The column body of the stand 300 is distributed with mounting holes matched with the locking bolt 350. (The mounting holes are shielded by the sleeve, so the mounting holes are omitted in the figure)

[0041] In practice, the working process is as follows:

[0042] First, the height of the traction rope 200 is adjusted according to the height of the patient: the sleeve 320 is moved along the column 300 until the threaded hole 340 is aligned with a mounting hole, and the locking bolt 350 is rotated into the mounting hole to fix the position of the sleeve 320 on the column 300. In practice, the number of threaded holes 340 and locking bolts 350 can be two or more. To facilitate the alignment of the threaded hole 340 and the mounting hole, a scale mark corresponding to the mounting hole can also be provided on the column 300 based on the relative position of the sleeve 320 and the threaded hole 340. Then, the fingers of the patient are clamped by the finger clamping blocks distributed on the upper limb connecting part 100, and the index finger, middle finger, ring finger and little finger of the patient are sequentially inserted into the gap between two adjacent clamping blocks, and then the first arc-shaped plate 141 and the second arc-shaped plate 142 are adjusted synchronously to continuously press the sliders to approach each other until the fingers of the patient are clamped. Thus, the index finger of the patient is clamped by the first clamping block 161 and the second clamping block 162, the middle finger of the patient is clamped by the second clamping block 162 and the third clamping block 163, the ring finger of the patient is clamped by the fifth clamping block 165 and the third clamping block 163, and the little finger of the patient is clamped by the third clamping block 163 and the fourth clamping block 164. Thus, the fingers of different patients can be prevented from loosening from the upper limb connecting part 100. Then, the patient can perform independent traction training by pulling the traction rope 200 relative to the column 300. Thus, the doctor does not need to intervene. At the same time, since the clamping of the fingers is completed by mechanical structure, the problem of slipping and causing secondary injury during traction training is reduced.
