Description

Technical Field

[0001] The present invention belongs to the technical field of traction devices, and specifically refers to an orthopedic traction device. Background Art

[0002] Traction therapy utilizes the principle of action and reaction in mechanics. Through the traction of gravity, it acts on the affected limb to relieve the tension and retraction of soft tissues at the fracture and dislocation sites, so as to reduce the fracture or dislocation and achieve the purpose of treatment. Traction is divided into two categories: continuous skin traction and skeletal traction, which are mainly used for cervical fractures, pelvic fractures, femoral neck fractures, intertrochanteric fractures, femoral shaft fractures, and unstable tibiofibular fractures, etc. Among them, skin traction uses adhesive tape to stick to the skin or a foam sponge band to wrap around the limb, and indirectly pulls the bone through the skin and muscles; skeletal traction uses a Steinmann pin or a stainless steel needle to directly penetrate into the hard part of the bone and conducts traction through the pulley on the orthopedic bed frame.

[0003] During the treatment process of existing traction devices, long-term traction will compress blood vessels, resulting in poor blood circulation, and then causing swelling and pain. Although patients can be massaged, the patient's legs cannot move, and the contact position between the support structure and the legs is a massage dead corner. Medical staff cannot massage the compressed parts of the patient, and it is necessary to move the patient's legs significantly, which affects bone healing; in addition, the existing traction force is adjusted by replacing weight blocks, and the adjustment method is cumbersome.

[0041] For specific use, first install the docking and fixing device 101, place the docking and fixing device 101 on the hospital bed, and pull the docking outer shells 109 at both ends of the docking and fixing device 101. Put the bottom of the docking outer shell 109 on the edge of the bed, and rotate the docking knob 111. The rotation of the docking knob 111 drives the rotation of the docking screw rod 110, and the rotation of the docking screw rod 110 drives the rubber claw 112 to move upward. Clamp the edge of the bed with the top of the rubber claw 112 and the bottom of the fixed sliding cabin 103 to achieve the fixation of the matching docking mechanism 1. First, fix the patient's leg, adjust the horizontal position of the flexible and liftable traction mechanism 2, so that the flexible and liftable traction mechanism 2 is directly below the patient's leg. Place the patient's calf on the vibration airbag 207, and fix the patient's ankle with a foot support (existing medical equipment). Then connect the foot support to the traction cable 307 (connect the bone needle to the traction cable 307 during bone traction treatment). Rotate the docking connecting rod 114 to fix the traction base 201 and the fixed sliding cabin 103 to each other. Rotate the lifting runner 208. The rotation of the lifting runner 208 drives the rotation of the lifting screw rod 204, and the rotation of the lifting screw rod 204 drives the two sliding joints 203 to move away from each other. The angle between the bottom triangular arm 202 and the top triangular arm 205 increases, and the support platform 206 is lifted upward, and the patient's calf is raised. As the patient's calf is raised, the foot support pulls the traction slide plate 305 through the traction cable 307, and the traction slide plate 305 approaches the traction push plate 302. After the patient's calf is raised, rotate the adjustment worm 309. The rotation of the adjustment worm 309 drives the rotation of the adjustment worm wheel 308, and the rotation of the adjustment worm wheel 308 drives the rotation of the traction screw rod 311. The rotation of the traction screw rod 311 drives the traction push plate 302 to slide towards the traction slide plate 305. When the traction slide plate 305 contacts the traction spring 304, the traction cable 307 is tensioned. At this time, the magnitude of the traction force can be adjusted. Continue to rotate the adjustment worm 309. The adjustment worm 309 drives the traction screw rod 311 to rotate through the adjustment worm wheel 308. The rotation of the traction screw rod 311 drives the traction push plate 302 to continue to move towards the traction slide plate 305. At this time, the traction slide plate 305 remains stationary under the tension of the traction cable 307. Use the traction push plate 302 to squeeze the traction spring 304. At this time, the traction spring 304 is squeezed and deformed, and the elastic force of the spring acts on the traction slide plate 305. The traction slide plate 305 exerts a traction force on the patient through the traction cable 307. Due to the interaction of forces, the force generated by the deformation of the traction spring 304 is equal to the traction force on the patient. Subsequently, the magnitude of the traction force can be adjusted in a timely manner by rotating the adjustment worm 309;During the process of traction on the patient, the magnetic massage system 209 is started, and the reciprocating motor 216 is started first. The reciprocating motor 216 rotates to drive the half-tooth gear 215 to rotate. The half-tooth gear 215 rotates to mesh with the internal teeth on one side of the parallel gear ring 214, driving the parallel gear ring 214 to move forward. Then, the half-tooth gear 215 rotates to mesh with the internal teeth on the other side of the parallel gear ring 214, driving the parallel gear ring 214 to move backward. The half-tooth gear 215 drives the parallel gear ring 214 to move back and forth. The reciprocating movement of the parallel gear ring 214 drives the synchronous slide arm 213 to move back and forth. The reciprocating movement of the synchronous slide arm 213 drives the magnetic slide 212 to move back and forth. The magnetic slide 212 will contact the connecting electrode 211 during the reciprocating movement. The battery 219 is started. When the magnetic slide 212 contacts the connecting electrode 211, the electromagnet 217 on the magnetic slide 212 is turned on. After the electromagnet 217 is turned on, it attracts the permanent magnet 218. The permanent magnet 218 is attracted to press the deformation spring 220 and the vibrating airbag 207 downward. Since the gravity of the patient's calf is evenly distributed on the vibrating airbag 207, when the vibrating airbag 207 is deformed by pressure and temporarily separated from the bottom of the patient's calf, the pressure borne by the vibrating airbag 207 is shared by its adjacent vibrating airbag 207. At the same time, as the magnetic attraction slide 212 slides back and forth, a single magnetic attraction slide 212 will reciprocate under the adjacent vibrating airbag 207. When the magnetic attraction slide 212 leaves the bottom of the vibrating airbag 207, the deformation spring 220 recovers and stretches to push the vibrating airbag 207, and the vibrating airbag 207 re-supports and contacts the patient's leg. Therefore, the adjacent vibrating airbags 207 alternately support the patient's calf, thereby relieving muscle tension, helping to relax the calf muscles, reducing tension, and promoting blood circulation. ;
