It is designed to provide a stable platform that allows doctors to perform microscopic examination and treatment of the shoulder joint.

[0003] For example, the application with publication number CN202740055U discloses a traction frame for shoulder arthroscopy surgery, including a bracket, a traction rope is placed on the bracket, one end of the traction rope is connected to a counterweight, and the other end is connected to a human upper limb restraint device, characterized in that: the bracket is also provided with at least one traction rope guide device that can make the guide pulley rotate arbitrarily in the horizontal and vertical directions, and the traction rope is placed on the guide pulley. When the utility model is used for shoulder arthroscopy surgery, the body position placement time is shorter than that of the traditional type (P<0.05), and the shoulder joint space distraction degree is greater than that of the traditional type. Therefore, the utility model is used in shoulder arthroscopy surgery, which is conducive to the placement of the body position, easy to operate during the operation to make the operation go smoothly, and has low production cost.

[0004] However, the mechanical traction of the equipment in this application has no braking function, and some emergencies caused by the equipment cannot be stopped or avoided in a safe way. Utility Model Content

[0005] The purpose of the present application is to provide an improved shoulder arthroscopy position traction frame in order to solve the problem that the mechanical traction of the above-mentioned device has no braking function, causing some emergencies of the device that cannot be stopped or avoided in a safe way.

[0006] The technical solution adopted in the present application is as follows: an improved shoulder arthroscopy position traction frame, comprising a main support column, a movable connecting piece is movably sleeved on the upper surface of the main support column, a main crossbeam is movably sleeved on the upper surface of the movable connecting piece, a mechanical brake component is fixedly connected to the surface of one end of the main crossbeam, a brake control rope is movably connected to the inner surface of the mechanical brake component, a brake button is provided on the outer surface of one end of the brake control rope, a traction rope is movably connected to the inner surface of the mechanical brake component, and force-bearing connecting blocks are fixedly connected to the inner surfaces of both ends of the traction rope.

[0007] By adopting the above technical solution, when in use, the traction at the upper end needs to pass through the lower surface corresponding to the main beam. By passing the traction rope through the inside of the mechanical brake, under normal circumstances, the device has the same effect as the conventional existing shoulder arthroscopy position traction frame for operating room nurses, and directly traction is performed on the patient. Through the two buttons of the brake button, one of which is turned on to make the mechanical brake have an extrusion spring inside, which provides a damping effect on the friction force of the outer surface of the traction rope, thereby reducing the traction tension, and the other directly performs emergency braking to keep the device in place and no longer generate pressure, protecting the user and the patient from continued use after adjustment. The effect of the overall device is improved on the existing basis, which is convenient for medical staff to directly start upgrading, ensuring the continuity of equipment application, avoiding the need to refer to the manual or re-training on the use of the equipment, thereby wasting the time of medical staff. The main support column is the main support of the entire device and the connection point for function realization. The main beam provides support at the upper end to ensure the traction of the traction rope at the top. The movable connecting piece connects the main beam and provides force buffering at the same time. The force-bearing connecting block and the traction rope are used for connection and transmission of force. The brake control rope ensures that the brake button can control the mechanical brake.

[0008] In a preferred embodiment, an angle adjustment rod is provided on the same side surface of the main cross beam and the mechanical brake component, and a rotating handle is movably connected to the surface of the end of the angle adjustment rod away from the mechanical brake component, and a fixed support beam is fixedly connected to the surface of the end of the angle adjustment rod close to the rotating handle, and the other end of the fixed support beam is welded to the main support column.

The lifting support block can fix the support member, and the rotation of the curling rod can curl the traction rope, so that the force can be adjusted at this location.

[0014] In a preferred embodiment, a drainage tube is fixedly connected to the inner surface of the supporting member corresponding to the curling rod, a traction rope is sleeved on the inner surface of the drainage tube, and a weight is movably connected to one end of the force-bearing connecting block.

[0015] By adopting the above technical solution, the drainage tube allows the device to be pulled from below, and the weights provide traction for the entire device through gravity and force transfer, thereby completing the overall effect of the device.

[0016] In a preferred embodiment, the lower surface of one end of the main beam corresponding to the mechanical brake is fixedly connected to a fixed pulley, the upper surface of one end of the main beam away from the mechanical brake is fixedly connected to a fixing part, the inner surface of one end of the main beam away from the mechanical brake is movably connected to an extension rod, and the lower surface of one end of the extension rod away from the main beam is also fixedly connected to a fixed pulley.

[0017] By adopting the above technical solution, the extension rod can be extended and retracted at one end of the main beam, and the fixing part can fix the extension rod to ensure the use effect of the equipment. The fixed pulley is used to guide the force of the traction rope above to ensure the overall effect.

[0018] In a preferred embodiment, a supporting fixture is fixedly connected in the middle of the outer surface of the main beam, a buffer pulley is fixedly connected to the outer surface of the supporting fixture, and a combing block is movably connected to the outer surface of the main beam between the movable connecting piece and the supporting fixture.

[0019] By adopting the above technical solution, the function of the buffer pulley is also to ensure the stability of the force of the other section above and to ensure the effect of the equipment. The combing block is movably connected on the main beam to ensure that the traction ropes are separated to avoid hidden dangers caused by force entanglement and easy damage to the equipment.

[0020] In a preferred embodiment, the brake control rope is movably connected to a multi-directional connector on the outer surface of one end away from the weight, and the outer surface of the lower end of the multi-directional connector is movably connected to a triangular connecting block, and a traction strip is provided on the outer surface of the triangular connecting block.

[0021] By adopting the above technical solution, the traction bar is used on the patient to achieve the traction effect of the shoulder arthroscopy position by the operating room nurse. The multi-directional connecting parts and triangular connecting blocks form force through connection to ensure the stable operation of the equipment.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In the present application, when in use, the traction at the upper end needs to pass through the lower surface corresponding to the main beam. By passing the traction rope through the inside of the mechanical brake, under normal circumstances, the device has the same effect as the conventional existing shoulder arthroscopy position traction frame used by operating room nurses, and directly traction is performed on the patient.
