Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an upper limb traction device. Background Art

[0002] Clinically, upper limb traction refers to a treatment plan that uses the body's strength to exercise the muscles of the patient's shoulders, wrists, and fingers, so as to enhance the flexibility of the muscles and ligaments in the corresponding parts and restore the patient's functional disorders and injuries to the finger joints. Currently, in clinical practice, manual traction is mainly performed by doctors holding the patient's affected limb. This plan consumes the doctor's manpower. At the same time, if the traction is not held properly during the operation, it is easy to slip and cause secondary injuries. Therefore, how to develop a new upper limb traction plan to overcome the above-mentioned problems in the prior art is a direction that technicians in this field need to study. Summary of the invention

[0003] The purpose of the present invention is to provide an upper limb traction device, which can realize autonomous traction training of the patient's affected limb without the intervention of a doctor, thereby reducing the workload of the doctor and reducing secondary injuries caused by slippage due to inaccurate grip.

[0004] The present invention discloses an upper limb traction device, which comprises:

[0005] An upper limb connection part, on which a plurality of clamping blocks for clamping fingers are distributed;

[0006] A traction rope, one end of which is fixedly mounted on the upper limb connecting portion as a whole;

[0007] The column extends in a vertical direction and has a bottom connected to a column base; the other end of the traction rope is installed on the column body of the column.

[0008] By adopting this technical solution: first, the finger clamps distributed in the upper limb connection part are used to clamp the fingers on the patient's affected limb, and then the patient can use the traction rope to perform autonomous traction training relative to the column. Therefore, no doctor intervention is required. At the same time, since the clamping of the fingers is completed by a mechanical structure, the problem of slippage and secondary injury during traction training is reduced.

[0009] Preferably, the upper limb connection portion comprises: an arc-shaped base plate, a traction connection plate, a first straight plate, a second straight plate, a first arc-shaped plate and a second arc-shaped plate;

[0010] The arc-shaped base plate is provided with a first arc-shaped groove, a second arc-shaped groove, a third arc-shaped groove, and a fourth arc-shaped groove; the arc-shaped base plate is also symmetrically provided with a first positioning block and a second positioning block;

[0011] A fifth clamping block is also installed on the arc-shaped base plate; a first slider is slidably installed in the first arc groove, and a first clamping block is installed on the first slider; a second slider is slidably installed in the second arc groove, and a second clamping block is installed on the second slider; a third slider is slidably installed in the third arc groove, and a third clamping block is installed on the third slider; a fourth slider is slidably installed in the fourth arc groove, and a fourth clamping block is installed on the fourth slider; the fifth clamping block is located between the second arc groove and the third arc groove;

[0012] One end of the first straight plate is rotatably connected to the first positioning block, the middle section of the plate is fixedly connected to the first sliding block as a whole, and the other end of the plate is rotatably connected to one end of the plate of the first curved plate;

[0013] One end of the plate body of the second straight plate is rotatably connected to the second positioning block, the middle section of the plate body is fixedly connected to the fourth sliding block as a whole, and the other end of the plate body is rotatably connected to one end of the plate body of the second curved plate;

[0014] The traction connecting plate is triangular in shape, and the other end of the plate body of the first arc plate and the other end of the plate body of the second arc plate are rotatably connected to the two corners of the traction connecting plate respectively; one end of the traction rope is connected to the third corner of the traction connecting plate.

[0015] By adopting this technical solution: the patient's index finger, middle finger, ring finger and little finger are sequentially inserted into the gap between two adjacent clamping blocks, and then the first arc plate and the second arc plate are synchronously adjusted to continuously pressurize each slider so that they are constantly close to each other until the patient's fingers are clamped. In this way, the patient's index finger can be clamped by the first clamping block and the second clamping block, the patient's middle finger can be clamped by the second clamping block and the third clamping block, the patient's ring finger can be clamped by the fifth clamping block and the third clamping block, and the patient's little finger can be clamped by the third clamping block and the fourth clamping block. In this way, it can be ensured that the fingers of different patients are prevented from being loosened from the upper limb connection part.

[0016] Preferably, the first clamp block, the second clamp block, the third clamp block, the fourth clamp block and the fifth clamp block are isosceles triangle clamp blocks respectively;

[0017] The first clamp block is rotatably connected to the first slider, the second clamp block is rotatably connected to the second slider, the third clamp block is rotatably connected to the third slider, the fourth clamp block is rotatably connected to the fourth slider, and the fifth clamp block is rotatably connected to the arc-shaped base plate.

[0018] By adopting this technical solution, the clamping method can be adjusted for patients with different finger sizes. Specifically, when the patient's finger size is large, each clamping block is adjusted to have its bottom edge facing away from the patient, so that during the insertion of the patient's finger, the clamping process from loose to tight is realized. When the patient's finger size is small, each clamping block is adjusted to have its bottom edge facing the patient, and the two opposite corners on the bottom edges of two adjacent clamping blocks are used to clamp the skin on both sides of the finger.

[0019] Preferably, the first clamping block, the second clamping block, the third clamping block, the fourth clamping block and the fifth clamping block are respectively made of elastic materials.

[0020] By adopting this technical solution: in the process of clamping the patient's fingers, the tactile sensation of the contact surfaces between both sides of the fingers and each clamping block is improved, and the wear of the skin on both sides of the fingers caused by the friction generated by the clamping blocks during traction is reduced.

[0021] Preferably, a sleeve is provided on the column body of the column, a buckle and a threaded hole are installed on the surface of the sleeve, and the other end of the traction rope is installed on the buckle; a locking bolt is rotatably connected to the threaded hole; and mounting holes matching the locking bolt are distributed on the column body of the column. The number of the mounting holes is configured to be several, and they are arranged in a straight line in the vertical direction.

[0022] By adopting this technical solution: according to the patient's height, the sleeve is moved along the column accordingly 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 sleeve position on the column can be relatively fixed.

[0023] In practice, the number of the threaded holes and locking bolts can be expanded to two or more. To facilitate the alignment of the threaded holes and the mounting holes, scale marking lines corresponding to the mounting holes can be provided on the column based on the relative positions of the sleeve and the threaded holes.

[0024] Therefore, the height of the other end of the traction rope is adjusted accordingly according to the specific height of the patient, so that it is suitable for use by patients of different heights.

[0025] Compared with the prior art, the present invention has the following technical advantages:

[0026] Firstly, the present invention can realize autonomous traction training of the patient's affected limb without the intervention of a doctor, thereby reducing the workload of the doctor and reducing secondary injuries caused by slippage due to inaccurate grip.

[0027] Secondly, the present invention can be used by patients of different heights and different finger sizes.

[0028] Finally, the invention has a simple structure and is easy to prepare and implement. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1, please refer to Figure 1-2 :

[0035] An upper limb traction device comprises: an upper limb connection part 100, a traction rope 200, and a column 300. The upper limb connection part 100 is used to clamp the patient's affected limb finger. One end of the traction rope 200 is fixedly installed with the upper limb connection part 100 as a whole; the other end of the traction rope 200 is installed on the column of the column 300.

[0036] Specifically, the upper limb connection part 100 includes: an arc-shaped base plate 110, a traction connection plate 120, a first straight plate 131, a second straight plate 132, a first arc-shaped plate 141 and a second arc-shaped plate 142. The arc-shaped base plate 110 is an arc-shaped thin plate structure, and the surface of the plate body is provided with a first arc-shaped groove 111, a second arc-shaped groove 112, a third arc-shaped groove 113, a fourth arc-shaped groove 114 and a fifth clamping block 165. Among them, the second arc-shaped groove 112 and the third arc-shaped groove 113 are symmetrically distributed on both sides of the fifth clamping block 165, and the first arc-shaped groove 111 and the fourth arc-shaped groove 114 are symmetrically distributed on both sides of the fifth clamping block 165. The outer edge of the plate body of the arc-shaped base plate 110 is also symmetrically installed with a first positioning block 171 and a second positioning block 172.

[0037] A fifth clamping block 165 is also installed on the arc-shaped base plate 110; a first slider 151 is slidably installed in the first arc groove 111, and a first clamping block 161 is installed on the first slider 151; a second slider 152 is slidably installed in the second arc groove 112, and a second clamping block 162 is installed on the second slider 152; a third slider 153 is slidably installed in the third arc groove 113, and a third clamping block 163 is installed on the third slider 153; a fourth slider 154 is slidably installed in the fourth arc groove 114, and a fourth clamping block 164 is installed on the fourth slider 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 section of the plate body is fixedly connected to the first slider 151 as a whole, and the other end of the plate body is rotatably connected to one end of the plate body of the first curved 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 section of the plate body is fixedly connected to the fourth slider 154 as a whole, and the other end of the plate body is rotatably connected to one end of the plate body of the second curved plate 142; the traction connecting plate 120 is triangular in shape, and the other end of the plate body of the first curved plate 141 and the other end of the plate body of the second curved plate 142 are respectively rotatably connected to the two corners of the traction connecting plate 120 as a whole; one end of the traction rope 200 is connected to the third corner of the traction connecting plate 120.

[0039] In this 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 respectively made of elastic materials such as rubber. The first clamp block 161 is rotatably connected to the first slider 151, the second clamp block 162 is rotatably connected to the second slider 152, the third clamp block 163 is rotatably connected to the third slider 153, the fourth clamp block 164 is rotatably connected to the fourth slider 154, and the fifth clamp block 165 is rotatably connected to the arc-shaped base plate 110.

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

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

[0042] First, the height of the other end of the traction rope 200 is adjusted according to the height of the patient: the sleeve 320 is moved along the column 300 accordingly until the threaded hole 340 is aligned with a certain mounting hole, and the locking bolt 350 is rotated to enter the mounting hole, so that the sleeve 320 position on the column 300 can be relatively fixed. In practice, the number of the threaded hole 340 and the locking bolt 350 can be configured to be two or more. In order to facilitate the alignment of the threaded hole 340 with the mounting hole, a scale mark line corresponding to the mounting hole can also be set on the column 300 based on the relative position of the sleeve 320 and the threaded hole 340. Subsequently, the finger clamps distributed on the upper limb connection part 100 are used to clamp the fingers on the patient's affected limb, and the patient's index finger, middle finger, ring finger and little finger are sequentially extended into the gap between two adjacent clamps, and then the first arc plate 141 and the second arc plate 142 are synchronously adjusted to continuously pressurize each slider so that they are constantly close to each other until the patient's fingers are clamped. Thus, the first clamp block 161 and the second clamp block 162 can be used to clamp the patient's index finger, the second clamp block 162 and the third clamp block can be used to clamp the patient's middle finger, the fifth clamp block 165 and the third clamp block 163 can be used to clamp the patient's ring finger, and the third clamp block 163 and the fourth clamp block 164 can be used to clamp the patient's little finger. Thus, it can be ensured that the fingers of different patients are prevented from being loosened from the upper limb connection part 100. Then, the patient can use the traction rope 200 to perform autonomous traction training relative to the column 300. Thus, no doctor intervention is required. At the same time, since the clamping of the fingers is completed by a mechanical structure, the problem of slippage and secondary injury during traction training is reduced.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
