The invention provides an adjustable shoulder joint traction frame device which comprises a transverse rod, a bearing longitudinal rod and an auxiliary longitudinal rod. The transverse rod comprises a secondary rod and a primary rod, the secondary rod can be nested in the primary rod, the secondary rod and the primary rod can be extended and retracted relative to each other, a slide groove is formed inside the primary rod along the horizontal direction, a slider capable of sliding in the horizontal direction is arranged in the slide groove, and a rotary pin with a radial screw hole is arranged on the slider; the upper end of the bearing longitudinal rod is fixedly connected with the primary rod, and the lower end of the bearing longitudinal rod is fixedly connected with a surgical bed; the auxiliary longitudinal rod is restrained in such a manner that the auxiliary longitudinal rod cannot be lifted, a threaded section is arranged on the top of the auxiliary longitudinal rod and is connected with the radial screw hole of the rotary pin on the slider inside the primary rod in a threaded manner, and a driving handle is arranged at the bottom of the auxiliary longitudinal rod. The adjustable shoulder joint traction frame device has the advantages that the horizontal direction, the length and elevation angles of the transverse rod can be adjusted in surgery procedures at any time as needed, the adjustable shoulder joint traction frame is easy to adjust and operate, and matching can be completely carried out by a single circulating nurse.
Description
technical field [0001] The invention relates to a device for shoulder joint traction in lateral lying position in shoulder arthroscopic surgery. Background technique [0002] A general upper limb traction frame for shoulder arthroscopic surgery includes a vertical bar and an arc-shaped bar extending from the top of the vertical bar. A pulley is respectively arranged on the top of the vertical bar and the extension end of the arc-shaped bar. A traction rope, one end of the traction rope close to the vertical bar is connected to the counterweight, and the other end is provided with a human upper limb restraint device for fixed connection with the forearm of the surgical object. In this way, through the weight of the counterweight, the arm of the operation object is pulled up obliquely, so as to facilitate the smooth progress of the operation. At the same time, the weight of the counterweight can be adjusted to meet different needs. [0003] And the shortcoming of prior art i...
