Reclining elbow joint surgery aid

The invention provides a technical field of surgical auxiliary instruments, in particular to provide a reclining elbow joint surgery auxiliary device.

According to the arthroscopy, elbow joint surgery is one of the new minimally invasive surgery developed by the current orthopedics. However, if the patient adopts the traditional prone posture for elbow joint surgery, it is not conducive to the operation of arthroscopy. The operation can be performed in a reclining posture, so that the arthroscope has sufficient space for operation, and another advantage of the surgical method is that after the elbow arthroscopy is performed, only the patient's arm needs to be moved. Other types of surgery are performed immediately, and the amount of bleeding is less because the arm is higher than the heart during surgery, and the burden on the patient is also small.

However, the disadvantage of this reclining surgery is that the arm does not have a proper supporting tool, and the patient's arm is supported by the intern to assist the patient's arm during the operation. The entire operation is very burdensome for the interns. Not only is there some uncertainty, but the precise position of the patient's arm, such as height and angle, cannot be fixed. It is easy to affect the success of arthroscopic surgery, so it is not a The ideal way and increase the risk of surgery.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure with more ideal and practicality, the clinical surgeons are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related medical surgical auxiliary device products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

The disadvantage of using this type of reclining surgery is that there is no proper support tool, and the patient's arm is supported by the intern to assist the patient's arm during the operation.
