Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a bone traction device capable of adjusting counterweight. Background Technique

[0002] The orthopedic device "Brown's traction frame" is a professional device used in the medical field, mainly for the traction and reduction treatment of orthopedic diseases such as lower limb fractures and dislocations. In the prior art, the traction force source of the affected limb is usually applied by using counterweights of different weights through the lever principle.

[0003] Clinically, the counterweight is fixed by tying the two handle straps of a disposable plastic bag together to wrap the counterweight, and then hanging the hanging holes on the handle straps of the plastic bag on the traction rope hook. If the two handle straps of the plastic bag are loosened or the counterweight excessively breaks through the bag body of the plastic bag, it is extremely easy for the plastic bag wrapping the counterweight to fall off the traction rope hook or the counterweight to fall out from the broken opening where the plastic bag is broken. The affected limb loses the traction force of the counterweight, thereby affecting the traction requirement of the affected limb. At the same time, there is an accidental situation where the falling counterweight may hit someone's instep during the falling process. Therefore, a bone traction device capable of adjusting counterweight is designed and produced here to solve the above problems. Content of the Utility Model

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This embodiment provides a bone traction device capable of adjusting the weight, such as Figure 1 and Figure 5 As shown, it includes: a counterweight component, the counterweight component includes a traction belt 2, a collection tube 26 located on the ground, and a plurality of counterweight blocks 25 built into the collection tube 26, one end of the traction belt 2 is connected to an upper cover 23, a lifting rod 24 is fixed to the bottom end of the upper cover 23, a pick block 28 is fixed to the radial side wall of the bottom end of the lifting rod 24, the counterweight block 25 is axially provided with a through hole for the lifting rod 24 to pass through, a matching hole 25A is provided on the radial side wall of the through hole for the pick block 28 to slide through, an annular rotating groove is provided on the bottom wall of the counterweight block 25, and a shelf groove 25B is provided on the top wall of the annular rotating groove, as shown in FIG. Figure 4 The shelf groove 25B and the matching hole 25A are not in the same vertical plane, that is, the shelf groove 25B and the matching hole 25A are staggered. Figure 4 The middle shelf groove 25B and the matching hole 25A are arranged perpendicularly to each other, so that the picking block 28 can rotate in the annular rotating groove with the lifting rod 24 as the rotation center after passing through the matching hole 25A. When the picking block 28 is rotated to a position directly opposite to the shelf groove 25B, the lifting rod 24 is pulled back upward to embed the picking block 28 into the shelf groove 25B. The space inside the shelf groove 25B is used to store the picking block 28. As long as the lifting rod 24 does not slide downward at will, the picking block 28 will not fall out of the shelf groove 25B.

[0024] The other end of the traction belt 2 is a traction end, and the traction belt 2 is used to be bound together with the patient's affected limb, so that the entire weight-bearing component pulls the affected limb to stretch.

[0025] The specific counterweight traction process is as follows: The patient lies flat on a single hospital bed. The collection cylinder 26 binds the traction end to the patient. The traction belt 2 bypasses along the upper end surface of the support plate erected at the end of the hospital bed and changes direction downward to connect to the upper cover 23. At this time, the collection cylinder 26 is located on the ground at the tail of the hospital bed, and the upper cover 23 and the collection cylinder 26 are coaxially distributed. The lifting rod 24 can pass through the through hole of the counterweight block 25, and at the same time, the picking block 28 passes through the matching hole 25A. The weights of multiple counterweight blocks 25 located in the collection cylinder 26 are all equal. According to the traction stretching counterweight requirements of the patient, the corresponding number of counterweight blocks 25 needs to be tractioned. After the picking block 28 passes through the matching hole 25A, it can rotate in the annular rotating groove with the lifting rod 24 as the rotation center. When the picking block 28 rotates to a position where it is vertically aligned with the placement groove 25B, then pull the lifting rod 24 upward to embed the picking block 28 into the placement groove 25B, and the counterweight block 25 can be hooked, the traction belt 2 is tightened, and the vertical length is shortened, and the corresponding number of counterweight blocks 25 can be tractioned to be set in the air to provide counterweight traction for the affected limb.

[0026] For example, the weight of each counterweight block 25 is 1 kg. Suppose the affected limb of the patient requires a counterweight of 6 kg. Then lower the position of the lifting rod 24 together with the picking block 28. After the picking block 28 passes through the matching holes 25A of 3 counterweight blocks 25 from top to bottom, it enters the annular rotating groove of the corresponding counterweight block 25. Rotate the lifting rod 24 to drive the picking block 28 to rotate in the annular rotating groove. When the picking block 28 rotates to a position where it is vertically aligned with the placement groove 25B, then pull the lifting rod 24 upward to embed the picking block 28 into the placement groove 25B. When using the picking block 28 to hook the third counterweight block 25 and lift the counterweight block 25 upward into the air, the third counterweight block 25 can support the first and second counterweight blocks 25 to provide a counterweight of 6 kg for the affected limb. Of course, if a heavier counterweight is needed, repeat the above steps and use the picking block 28 to hook more counterweight blocks 25.

[0027] In summary, adjust the counterweight according to the specific situation and treatment requirements of the patient to achieve the best traction effect, which can not only meet the counterweight requirements but also avoid excessive counterweight, resulting in excessive tensile force on the affected limb and causing the traction direction to deviate from the best straight path, affecting the traction rehabilitation effect of the affected limb.

[0028] It should be further noted that the collection cylinder 26 is used here as the storage member for storing multiple counterweight blocks 25. After the picking block 28 hooks the corresponding counterweight block 25 and pulls it upward into the air, the counterweight block 25 is always located directly above the collection chamber of the collection cylinder 26. Even if it falls, the movement trajectory of the counterweight block 25 can only be a free-fall motion, falling from top to bottom, and finally it will still fall into the collection cylinder 26, and it is not easy to deviate from the position of the collection cylinder 26 and fall on the ground, thus avoiding the situation of injuring the feet of passing personnel. Moreover, a rubber chassis 27 can be fixed at the bottom end of the collection cylinder 26. The diameter of the rubber chassis 27 is larger than that of the collection cylinder 26. On the one hand, the rubber chassis 27 can enhance the friction between the collection cylinder 26 and the ground and is not easy to slip sideways. On the other hand, once the counterweight block 25 falls and hits inside the collection cylinder 26, the rubber chassis 27 can absorb the impact force of the counterweight block 25 hitting the inner bottom wall of the collection cylinder 26 and reduce the noise at the same time.

[0029] In this embodiment, further, the traction end is connected with a widened cloth belt 21. Both side edges of the widened cloth belt 21 are connected with straps 22. The ends of the two opposite straps 22 on both side edges are wound and bound around the affected limb, attaching the widened cloth belt 21 to the position to be bound on the patient, winding the two side straps 22 around the affected limb, and choosing to stick them with Velcro.

[0030] As Figure 1 、 Figure 2 and Figure 3 shown, it further includes a support member. The support member includes a retaining cross beam 1, a sliding frame 11 and an I-shaped guiding support wheel 14. Both ends of the retaining cross beam 1 are detachably connected between the side edges of the two bed boards of the hospital bed. There are two sliding frames 11, and the sliding frames 11 are adjustably arranged on the retaining cross beam 1. A support inclined rod 12 is obliquely fixed at the upper end of the sliding frame 11. Hinged joints of the top ends of the opposite side walls of the two support inclined rods 12 are connected with connecting rods 13. The two connecting rods 13 are distributed in a V-shaped structure. Moreover, both ends of the retaining cross beam 1 are bent downward to form longitudinal limiting baffles. The longitudinal limiting baffles are parallel to the side walls of the bed board of the hospital bed. Threaded holes are opened in the longitudinal limiting baffles. A fastening bolt 15 is threadedly inserted into the threaded holes. After passing through the threaded holes, the fastening bolt 15 is connected with a pressing disc 16 that can abut against the side edge of the bed board of the hospital bed. The retaining cross beam is spanned across the end of the hospital bed, and the two longitudinal limiting baffles are located on both sides of the hospital bed. Manually rotate the fastening bolt 15 to tightly press the pressing disc 16 against the side frames on both sides of the hospital bed, so as to install the retaining cross beam 1 at the end position of the hospital bed. Subsequently, one end of the traction belt 2 is bound to the affected limb, and the other end pulls the counterweight block 25. The traction belt 2 bypasses the I-shaped guiding support wheel 14 supported in the air by the two connecting rods 13.

[0031] Slide the two sliding frames 11 along the retaining crossbeam 1 towards the side closer to each other. The two support diagonal rods 12 come together, the included angle between the two connecting rods 13 becomes smaller, and the support height of the I-shaped guiding support wheel 14 decreases. At this time, it is convenient to lower the traction height of the traction belt 2 and the height of the lower bar picking block 28, so as to hook more counterweight blocks 25 and meet the traction counterweight of a greater weight. Subsequently, reverse-adjust the two sliding frames 11, increase the included angle between the two connecting rods 13, and raise the height of the I-shaped guiding support wheel 14, then the counterweight block 25 can be pulled into the air for traction counterweight of the affected limb. No matter how the sliding frame 11 is adjusted, when it is necessary to lift the traction counterweight block 25 into the air, it is necessary to raise the support height of the I-shaped guiding support wheel 14 to ensure that the counterweight block 25 can be lifted into the air. At this time, convex blocks are fixed on both sides of the upper end surface of the retaining crossbeam 1, a threaded rod 17 is fixed between the two convex blocks, a push plate 18 is threadedly sleeved on the outer wall of the threaded rod 17, the two push plates 18 are located in the space between the two sliding frames 11, an enlarged portion extends radially from the end of the push plate 18 facing the sliding frame 11, and the side wall of the end of the enlarged portion is in contact with the side wall of the sliding frame 11. Rotate the two push plates 18 respectively, and rotate and adjust the two push plates 18 along the axial direction of the threaded rod 17 towards the side away from each other. Use the enlarged portion of the push plate 18 to push the two sliding frames 11 to slide away from each other. Since the traction belt 2 bypasses the I-shaped guiding support wheel 14, the I-shaped guiding support wheel 14 has a force pressing downward in real time. The two connecting rods 13 can rotate downward around various corresponding hinge positions, and the two support diagonal rods 12 and the sliding frame 11 have a tendency to slide together and close. Use the enlarged portion of the push plate 18 to block the two sliding frames 11 from sliding together and closing. In this way, the height of the I-shaped guiding support wheel 14 will not decrease, ensuring that the counterweight block 25 lifted into the air will not contact the inner bottom wall of the collection cylinder 26, resulting in the inability to reach the preset counterweight weight.

[0032] The support diagonal rod 12 here is distributed obliquely in the direction indicated by arrow A as Figure 3 shown, and the included angle between the support diagonal rod 12 and the sliding frame 11 is as Figure 3 the described S, and the included angle of S is 60°. In this way, the lateral position of the connecting rod 13 hinged to the side wall of the end of the support diagonal rod 12 can cross the upper end surface of the support plate erected at the end of the hospital bed, so as to stretch the lateral distance of the traction belt 2 extending out of the end of the hospital bed, avoiding the vertical part of the traction belt 2 from rubbing against the end frame during traction, which affects the long-term use of the traction belt 2 and is prone to excessive wear and breakage.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
