Description
Technical Field
The utility model relates to a shoulder joint operation medical instrument, in particular to a traction frame which can be used for shoulder arthroscope minimally invasive surgery in surgical operations.
Background
The minimally invasive operation of the shoulder arthroscope requires that the joint gap of the shoulder joint of a patient is opened by an auxiliary traction device in a lateral lying state, and then the operation can be carried out. Surgical traction frames that can be used for this type of surgery are disclosed in the prior art CN 203970561U and CN 204121090U.
For example, CN 204121090U discloses a traction frame for shoulder arthroscopy surgery, which comprises a traction frame main body composed of a cross bar and a vertical bar and having a "T" shape, pulleys arranged at two ends of the cross bar, and a traction rope assembled on a pulley groove, wherein the vertical bar is connected with a non-midpoint position of the cross bar in a matching manner, an installation part is arranged at the upper part of the vertical bar, a hinge hole and an adjusting hole are arranged on the installation part, and the adjusting hole is distributed in an arc shape by taking the hinge hole as a circle center; two ends of the traction rope are provided with connecting buckles, one connecting buckle is detachably connected with a binding arm sheath, and the other connecting buckle is connected with a heavy object.

However, in practical structure, the angle of the cross rod and the length of the arm can be adjusted in a large range when the arm angle of the traction frame is adjusted flexibly, and even if the vertical rod is symmetrically connected with the cross rod, the arm angle can be adjusted flexibly as long as the connecting position can be changed.
Of course, the above-described prior art has the following drawbacks. During operation, the arm of a patient is stretched to form a certain angle through the traction rope on the cross rod, however, the arm is forced to droop by the weight of the arm, an included angle exists between the direction of the stretching force of the traction rope and the gravity direction of the arm, and the trend that the arm is made to droop by gravity cannot be completely overcome no matter how large the traction force of the traction rope is. Moreover, the traction force that the arm of the patient can bear is limited, after the angle is set for the operation, the arm stretching length changes along with the traction time, and the influence of the arm gravity causes that the arm is difficult to keep the originally set position in the operation process, and the arm needs to be lifted by the operator in the operation process to avoid arm droop. There is therefore a need for an improved construction of a shoulder arthroscopic surgical retractor which overcomes the above-mentioned deficiencies of the prior art.
