Description

Technical Field

[0001] This utility model relates to a traction device for an operating table, specifically a quick-connect traction frame for an orthopedic operating table, belonging to the field of medical device technology. Background Technology

[0002] Currently, for patients requiring surgery, electric operating tables are commonly used in operating rooms to position the patient for ease of operation by medical staff. Existing electric operating tables typically have an extendable and removable extension panel at the foot of the bed, with a sponge pad placed on it. However, for patients with proximal femoral fractures who require continuous traction during surgery and to facilitate intraoperative fluoroscopy, additional auxiliary devices are needed. For example, a traditional orthopedic traction frame can be connected at the foot of the operating table to traction or fix the patient's foot and leg.

[0003] However, the orthopedic traction frames used in existing technologies for operating tables still have the following drawbacks in actual use:

[0004] 1) To ensure stability during use, the bottom of the orthopedic traction frame for the operating table is usually fixed to the ground or connected to the bottom of the operating table. This makes the installation and disassembly of the traction frame difficult, resulting in poor portability of the traction table.

[0005] 2) The orthopedic traction frame for the operating table is composed of multiple support rods connected to the support plate to ensure support, which makes the structure bulky, inconvenient to install and store at any time, and increases the manufacturing cost.

[0006] Therefore, there is an urgent need to design an operating table traction aid that can be quickly installed or stored, and that has a simple structure and low manufacturing cost. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a quick-connect traction frame for orthopedic operating tables. By designing a detachable traction device, it achieves the purpose of quick fastening and installation, and the structure is ingeniously designed so that it can be disassembled at any time. By designing a flip-folding traction device, it achieves the purpose of quick folding and storage, and the structure is simple and easy to use.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect traction frame for an orthopedic operating table, comprising a detachable traction device that is snapped and fixed to the operating table leg plate, wherein the operating table leg plate consists of two symmetrical leg plate extension structures, and both leg plate extension structures are rotatably connected to the tail of the operating table in the direction of outward rotation, and both outer sides of the operating table leg plate are connected to steel rails for fixing auxiliary components of the operating table via connecting columns.

[0009] The detachable traction device includes a detachable frame that matches the width of the leg extension structure. The front end of the detachable frame has slots on both sides along the length direction, and the outer edge of the slots is flush with the front end of the detachable frame. The rear end of the detachable frame has a first pulley vertically installed. The detachable traction device is inserted into the leg extension structure of the operating table leg board through the cooperation between the slots on both sides and the connecting column.

[0010] A fixing column is also fixedly connected to the outer wall of the detachable frame located inside the slot, and the center of the fixing column is located on the transverse center line of the slot. A rotating arm is rotatably connected to the fixing column, and a buckle head is also obliquely connected to the end of the rotating arm. The detachable traction device is fastened to the leg extension structure of the operating table leg board by the cooperation and fastening between the rotating arm and the buckle head and the connecting column.

[0011] Furthermore, the angle of the buckle head at the end of the rotating arm is 60°~90°, the distance between the inner side of the buckle head and the inner side of the slot is greater than the diameter of the connecting column; and the rotating arm is configured as a telescopic structure with threaded heads at both ends and a threaded rod in the middle.

[0012] Furthermore, the diameter of the connecting post is 1cm, the width of the corresponding slot is 1.5cm, the length is 11cm, and the distance from the inner side of the buckle head to the center of the fixing post is 5cm.

[0013] Furthermore, the width of one leg extension structure in the operating table leg is 24cm and the length is 50~60cm; the width of the detachable frame is 24.5~25cm, the length is 85cm, the thickness is 7.5cm, and the height of the first pulley is 18cm.

[0014] Furthermore, the frame, connecting column, steel rail, and detachable traction device of the operating table leg board are all made of stainless steel, and insulating rubber pads or sponge pads are attached to the upper surface of the operating table leg board and the detachable traction device.

[0015] This utility model also discloses a quick-connect traction frame for an orthopedic operating table, including a flip-fold traction device that is rotatably connected to the leg plate of the operating table. The leg plate of the operating table consists of two symmetrical leg plate extension structures, and both leg plate extension structures are rotatably connected to the tail of the operating table in the direction of outward rotation. Each leg plate extension structure has connection holes on both outer sides at the rear end.

[0016] The flip-fold traction device includes a flip-fold frame that matches the width of the leg extension structure. Both sides of the front end of the flip-fold frame are provided with connecting ears with holes along the length direction. A second pulley is vertically provided on the rear end of the flip-fold frame. The flip-fold traction device is rotatably connected to the leg extension structure of the operating table leg board through a fixed shaft passing through the connecting ears and connecting holes on both sides.

[0017] Furthermore, the width of one leg extension structure in the operating table leg is 24cm and the length is 50~60cm; the width of the flip-up folding frame is 24.5~25cm and the length is 50~60cm, and the height of the second pulley is 16~18cm.
