Description

The present invention relates to a shoulder joint position adjusting device that displaces the position of the shoulder joint of a treated patient.

Cervical spine diseases such as herniated disk, cervical spondylosis, and ossification of the posterior longitudinal ligament of the cervical spine cause paralysis, numbness, and pain in the extremities, but degenerative diseases often occur in the lower cervical spine. If there is a method of using an instrument such as a cervical spine correction pillow, but the patient is paralyzed or the pain that resists conservative therapy continues, surgical treatment is required because the conservative therapy becomes a temporary palliative therapy. Since it is not possible to confirm the high level of surgery only by visually observing the surgical field, it is necessary to perform diagnostic imaging such as X-ray photography. Furthermore, it is necessary to install artificial bones, screws, plates, and other artificial objects depending on the disease, but at that time, it is necessary to perform image diagnosis by visual inspection and X-ray photography to confirm that the installation is correct.

Examples of the above-mentioned conventional techniques for surgical treatment and surgical treatment include the following documents.

In the above-mentioned conventional technique, when the X-ray of the cervical spine treatment site is seen, the shoulder joint is reflected in the lower cervical spine (for example, the 7th cervical spine) in a supine position on the operating table, and becomes a black shadow. , The lower cervical spine cannot be clearly projected. Therefore, accurate surgery at an appropriate high level becomes difficult.

Therefore, while trying to change the posture of the patient or other methods, the present inventor pulls the upper limb caudally in the supine position, so that the shoulder joint is displaced and separated from the site of the lower cervical spine to see through the roentgen. It was found that the overlapping state can be avoided in. Therefore, it was found that if such a state can be stably maintained, it will be easier to perform surgery.

In view of the above-mentioned current situation, it is an object of the present invention to easily perform X-ray fluoroscopy of the lower cervical spine site with a simple device and to facilitate surgery.

The shoulder joint position adjusting device according to the present invention is a shoulder joint position adjusting device in order to achieve the above object, and is in contact with the back surface installed on the operating table and does not easily move due to frictional resistance. It is composed of a pedestal (1) and a forearm holder (3) that can be detachably fixed to the pedestal (1) by a surface fastener (2) at an arbitrary traction position. A shoulder joint position adjusting device characterized by being
The shoulder joint referred to here refers to the bones constituting the shoulder joint such as the scapula, the upper part of the humerus, and the clavicle.

In the present invention, the operating table and the pedestal are locked by friction, but other fixing means (fasteners) may be added.
Further, the traction of the upper limb refers to a normal stretched state in which the arm is grasped and pulled toward the toe side in a relaxed state of the muscle of the human body, and the muscle is stretched while the joint remains as it is.

The present invention was invented with inspiration from the findings gained from many experiences related to cervical spine surgery. According to the shoulder joint position adjusting device of the present invention, the forearm was held, pulled, and pulled. The position of the shoulder joint can be displaced downward (toe side) to a fixed state simply by temporarily fixing it at the position, so that the shoulder joint overlaps with the lower cervical spine during roentgen imaging. This can be avoided, and the surgical field at the site can be opened so that the surgical equipment can be operated precisely.
Other advantages of the invention will become apparent from the description of the examples below.
