Description

Technical Field

[0001] This utility model belongs to the field of fracture rehabilitation technology, and in particular relates to a traction frame that is easy to assemble. Background Technology

[0002] A fracture traction frame is a widely used medical device in fracture treatment. It provides stable support and traction to help doctors correctly locate and manipulate the patient's bones, promoting fracture reduction, fixation, and healing. The principle of a fracture traction frame is to treat fractures, dislocations, and other injuries by applying appropriate traction force. Traction force can relieve pain, reduce soft tissue tension, correct deformities, and maintain limb functional positioning, thus helping patients recover sooner. Specifically, traction force can stabilize the fracture ends, reduce pain, and promote fracture healing. Simultaneously, traction can improve venous blood return and help eliminate limb swelling. Fracture traction frames play an important role in fracture treatment; proper use and maintenance of the traction frame can ensure the patient's treatment effectiveness and safety.

[0003] The existing authorized public account CN221786896U discloses a traction frame that is easy to assemble, including a support block. The surface of the support block has a slot, and a support rod is engaged inside the slot. The support rod has a rectangular groove, and a locking block is engaged inside the rectangular groove. A horizontal frame is fixedly connected to one side of the locking block. A groove is formed on the inner wall of the horizontal frame, and a slider is slidably connected inside the groove. A connecting block is fixedly connected to the bottom of the slider, and a fixing plate is fixedly installed at one end of the connecting block by bolts. This easily assembled traction frame, through the arrangement of a servo motor, a cylinder, a drum, and a suspension rope, allows medical personnel to place the patient's legs on an arc-shaped placement plate. Then, the servo motor is activated, driving the drum to rotate. The rotation of the drum retracts the suspension rope, raising the arc-shaped placement plate to a suitable height, thereby improving the comfort of leg placement. However, the aforementioned easy-to-assemble traction frame only has one set of arc-shaped placement plates installed, which can only meet the traction needs of one leg of the patient and cannot meet the treatment needs of patients who need traction of both legs. Therefore, it is necessary to provide an easy-to-assemble traction frame to solve the above problems. Utility Model Content

[0025] Preferably, the mounting frame 1 is configured as an inverted U-shaped structure, with a set of mounting sleeves 2 installed on both sides of its bottom. The mounting sleeves 2 are configured as having an open bottom so that the two sets of mounting sleeves 2 can be installed onto the railing at the foot of the hospital bed.

[0026] Preferably, the size of the clamping plate 3 installed on the inner side of the mounting sleeve 2 is adapted to the inner size of the mounting sleeve 2. The second slider 12 installed on the top of the clamping plate 3 is set in the groove opened on the top of the inner side of the mounting sleeve 2. The second slider 12 is set as a T-shaped structure, so that the second slider 12 cannot be disengaged from the groove downwards. Thus, the clamping plate 3 can be installed on the inner side of the mounting sleeve 2, and the clamping plate 3 can move along the direction of the groove on the inner side of the mounting sleeve 2.

[0027] Preferably, the threaded rod 4 installed on the right side of the clamping plate 3 is rotatably connected to the clamping plate 3.

When the lower half of the fixation seat 7 is rotated to reset, the insert plate 13 is in the slot. Fixing holes are provided on both sides of the top right side of the lower half of the fixation seat 7, and fixing holes are provided on both sides of the insert plate 13. When the insert plate 13 is in the slot, the fixing holes on the insert plate 13 correspond to the fixing holes on both sides of the top right side of the lower half of the fixation seat 7, so that the insert plate 13 can be locked in the slot by two sets of fixing bolts, thereby realizing the overall fixed assembly of the fixation seat 7. The second cylinder 8 is fixedly installed at the bottom of the lower half of the fixation seat 7, and the upper end of the second cylinder 8 passes through the middle of the lower half of the fixation seat 7. The through hole extends into the inner side of the fixing seat 7. The top of the second cylinder 8 is fixedly connected to the bottom middle of the bottom of the two sets of fixing plates 9 installed on the inner side of the fixing seat 7. Six sets of springs 10 are symmetrically installed on the top of the top set of fixing plates 9. The top of the springs 10 is fixedly connected to the top of the inner side of the upper half of the fixing seat 7. The opposite side of the two sets of fixing plates 9 is set with an arc-shaped structure that conforms to the shape of the human leg. The opposite side of the two sets of fixing plates 9 is fitted with a soft plate 14. When the patient's leg is pulled, the patient's leg is between the two sets of fixing plates 9. At this time, the fixing seat 7 is closed and the bottom set of fixing plates 9 is pushed upward by the second cylinder 8, which can reduce the distance between the two sets of fixing plates 9, thereby clamping and fixing the patient's leg between the two sets of fixing plates 9, thus achieving fixation and traction of the patient's leg. The soft plate 14 is in contact with the patient's leg. The soft plate 14 is made of a soft material and has good breathability, which can increase the comfort of the patient's leg.
