Abstract
Description
Technical Field
[0001] The present invention relates to a shoulder joint position adjusting device that displaces the position of the shoulder joint of a patient undergoing treatment.
Background Art
[0002] Due to cervical spine diseases such as intervertebral disc herniation, cervical spondylosis, ossification of the posterior longitudinal ligament of the cervical spine, etc., limb numbness, tingling, pain, etc. occur, but those caused by degenerative diseases are more likely to occur in the lower cervical spine. There are methods of using devices such as cervical orthopedic pillows, but when there are cases of paralysis or persistent pain resistant to conservative treatment, surgical treatment is required because conservative treatment becomes only a temporary palliative treatment. Since it is impossible to confirm the high position of the surgery only by visually observing the surgical field, it is necessary to perform imaging diagnosis such as X-ray imaging. Furthermore, depending on the disease, it is necessary to install artificial objects such as artificial bone, screws, plates, etc., but at that time, in order to confirm whether they are correctly installed, imaging diagnosis by X-ray imaging is required together with visual observation.
[0003] As conventional techniques for the above-described treatment and surgical treatment, for example, the following documents can be cited.

Summary of the Invention
Problems to be Solved by the Invention
[0004] In the above-described conventional techniques, when performing X-ray fluoroscopy of the cervical spine surgery site, in the supine position on the operating table, the shoulder joint appears overlapping the lower cervical spine (for example, the seventh cervical vertebra) site, forming a black shadow, and the lower cervical spine site cannot be clearly imaged. Therefore, it is difficult to perform an accurate surgery at an appropriate high position.
[0005] Therefore, while attempting to change the patient's posture and other methods, the present inventor found that in the supine position, by pulling the upper limb caudally, the shoulder joint is displaced, separated from the lower cervical spine region, and the overlapping state in fluoroscopy can be avoided. Therefore, it was found that if such a state can be stably maintained, the surgery becomes easier to perform.
[0006] In view of the above-described current situation, an object of the present invention is to easily perform fluoroscopy of the lower cervical spine region with a simple device and make the surgery easier to perform.

The shoulder joint position adjusting device is characterized in that the forearm holding body (3) is configured to be fixed to the pedestal (1) at an arbitrary traction position. Here, the shoulder joint referred to herein means the bones constituting the shoulder joint such as the scapula, the upper part of the humerus, and the clavicle. by the hook-and-loop fastener (2), and is configured to be fixed to the pedestal (1) at an arbitrary traction position. Here, the shoulder joint referred to herein means the bones constituting the shoulder joint such as the scapula, the upper part of the humerus, and the clavicle. via the substrate (4), and is configured to be fixed to the pedestal (1) at an arbitrary traction position. Here, the shoulder joint referred to herein means the bones constituting the shoulder joint such as the scapula, the upper part of the humerus, and the clavicle.
[0008] In the present invention, the operating table and the pedestal are in a locked state by friction, but other fixing means (fasteners) may be added. Also, the traction of the upper limb refers to the normal stretching state in which the arm is grasped in a muscle-relaxed state of the human body and pulled toward the toe side, and the joint remains as it is while stretching the muscle.
Effects of the Invention
[0009] The present invention was invented by obtaining inspiration from the knowledge gained through numerous experiences related to cervical spine surgery. According to the shoulder joint position adjustment device of the present invention, by simply holding and pulling the forearm and temporarily fixing it in the pulled position, the position of the shoulder joint can be displaced downward (towards the foot side) and fixed, thereby avoiding the situation where the shoulder joint overlaps with the lower cervical vertebrae during X-ray imaging, opening up the surgical field at this site, and enabling precise operation of surgical instruments. Other advantages of the present invention will become apparent from the following description of the embodiments. Preferred embodiments for carrying out the invention

Embodiment
[0012] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The shoulder joint according to the present invention The position adjusting device is, as shown in FIGS. 1 and 2, a position adjusting device for the shoulder joint, Operating table and , the said It is composed of a pedestal 1 that contacts the back surface installed on the operating table and does not easily move due to frictional resistance, and a forearm holder 3 that can be detachably fixed by a hook-and-loop fastener 2 at an arbitrary traction position with respect to a substrate 4 that can be detachably engaged with the pedestal 1. FIG. 3 shows a state including a fluoroscopic view of the cervical spine region. 6 indicates the cervical spine, and 7 indicates the lower cervical vertebra (seventh cervical vertebra).
[0013] The forearm holder 3 is composed of a substrate 4 that can be detachably fixed to the pedestal 1 by a hook-and-loop fastener, and a forearm holding member 5 provided on the substrate 4. As shown in FIGS. 4(4a, 4b), the forearm holding member 5 is formed of a flexible material into a belt shape so that the forearm can be wound around. On the front side of FIG. 5a, cuts are made at two locations to facilitate winding of the belt. What protrudes at the cut portion in FIG. 5b is a holding member for the belt.
[0014] In this embodiment, the forearm holding member 5 is provided at two locations, the wrist side position and the elbow side position. However, the forearm holding member 5 may be provided at one location or at a plurality of locations. FIGS. 5(5a, 5b) show the front and back of the substrate 4. On the back surface (5b), a hook-and-loop fastener 5B for locking to the pedestal 1 is provided, and on the front surface (5a), at least one of a friction member or a hook-and-loop fastener 5A for locking to the substrate 4 is provided. Fig. 6 shows a belt-shaped body, which is made of a material such as felt that can surround the forearm. In Fig. 6, on the wrist side portion of this belt-shaped body, a soft material for contact, for example, urethane foam which is an example of foamed plastic, is attached. The elbow side portion is configured to be wider than the wrist side and is made of a slightly harder material, being considered to be stably supported. In this way, on the wrist side part of the forearm holding member (5), foamed plastic is provided at a position corresponding to contact with the wrist to exhibit a cushioning function. Particularly in the case of a patient with their own body weight (obese type), it prevents the belt-shaped body from directly contacting the wrist and causing redness or pressure sores. On the elbow side part of the forearm holding member (5), the foamed plastic is configured to be wide, enabling the dispersion and support of the body weight on the elbow side and avoiding the onset of pressure sores.
[0015] Similarly, for the pedestal 1 shown in Fig. 7, the back surface (7b) in contact with the operating table is a felt surface with a large frictional resistance. The front surface (7a) of this pedestal 1 is configured as a hook-and-loop fastener surface that engages with the back surface of the substrate 4 of the forearm holder 3. As shown in Fig. 7, considering pressure sore prevention, it is preferable to use a pedestal 1 made of a foamed plastic material to soften the local contact with the treatment table at the affected part or during treatment. However, other materials with a buffering function or combinations thereof may also be used. In addition, in Figs. 1, 4, 6, and 7, the dashed rectangle indicates the existence of the back surface.
[0016] The usage mode is to lay the subject (patient) supine on the operating table, wind the belt-shaped body around one forearm and fix it, pull the arm towards the foot side, confirm the state where the shoulder joint is displaced by X-ray imaging, and then fix the positions of the substrate 4 and the pedestal 1 with a hook-and-loop fastener. The operation by X-ray imaging is started in this state.
[0017] (Alternative mode) As shown in FIG. 8, here, the forearm holder 3 is constituted by a rubber glove 8 that can be tightly worn from the fingertips to the elbow side. On the rubber glove 8, a hook-and-loop fastener 8A is fixed to the side surface (particularly the back surface or the bottom surface), and the hook-and-loop fastener 8A is detachably engaged with the substrate 4. In this embodiment, the patient is asked to wear the rubber glove 8, and then, on the operating table, the patient is made to lie on his back, pull the hand toward the foot side, and fix the position with respect to the pedestal in the extended state. Therefore, in this method, it is easy to put on and take off the rubber glove, and due to the surface contact of the rubber glove and the close contact with the forearm, it is difficult to cause displacement, and it is easy to maintain the position of the displaced shoulder joint.
[0018] At the wrist side portion of the forearm holding member 5 shown in FIG. 4, foamed plastic is provided at a position corresponding to the contact with the wrist to exhibit a cushioning function, preventing the belt-like body from directly contacting the wrist and causing redness or bedsore. At the elbow side portion of the forearm holding member 5, the foamed plastic is configured in a wide width so as to enable the dispersion and support of the weight on the elbow side and avoid the onset of bedsore.
Industrial Applicability
[0019] The present invention is a simple device for performing a surgical operation on the cervical spine region. While being a simple device, X-ray imaging can be clearly observed and the operation can be easily performed, so it can be implemented without disturbing the existing surgical equipment.
