Description

An intraoperative head and neck immobilizer for reverse shoulder replacement surgery

technical field

The utility model relates to the technical field of head and neck fixation, in particular to a head and neck fixer in reverse shoulder replacement surgery.

Background technique

Reverse shoulder replacement is a surgical procedure in which the glenoid is removed, a prosthesis protruding from the shoulder blade is placed on the glenoid to form a joint, and then the soft tissue above is sutured.

The position of shoulder replacement surgery is to suspend the affected shoulder joint in the conventional "beach chair" position. Therefore, the head of the operating bed and the end of the bed should be exchanged, and the operating bed should be changed to the reverse position before placing the beach chair position. When performing surgery on a patient, half of the bed board needs to be removed, so that it is convenient to suspend the patient's shoulder joint, which is convenient for the surgeon's operation and intraoperative C-arm fluoroscopy. However, when the patient is suspended, the upper body of the patient is suspended. At this time, the patient's head and neck are easily swayed due to the loss of support, and the existing "beach chair" is difficult to support and prevent the patient's head and neck from swinging, so medical care is often required. Personnel hold the patient's head and neck for a long time, which can easily cause great discomfort to both the medical staff and the patient, which can easily affect the overall medical effect and quality.

When the handle is pulled, it can drive the insertion rod 6076 to move, and the movement of the insertion rod 6076 can drive the slide plate 6074 to move along the direction of the fixed rod 6073 and pull the first spring 6075. At this time, the movement of the slide plate 6074 can squeeze the second spring 6077. The rod 6076 moves out from the first jack and the second jack. At this time, the handle is moved upward, and the handle can move through the insertion rod 6076 to drive the fixed box 6072 to move, and the fixed box 6072 can move with the U-shaped plate 6071 along the vertical plate 9 Move in the direction until the U-shaped plate 6071 is separated from the vertical plate 9. When the U-shaped plate 6071 is separated from the vertical plate 9, the U-shaped plate 6071 can drive the horizontal bar and the mounting plate 601 to move to the top of the vertical plate 9. Therefore, the entire fixing mechanism 6 can be removed, thereby facilitating the patient to place the head on the headband 4 and the neck brace 5 .

A U-shaped adjusting plate 7 is fixedly connected at the middle position of the bottom of the mounting plate 601 . The top of the adjusting plate 7 is slidably connected with a return frame 8 , and the bottom of the return frame 8 is fixedly connected to the top of the support rod 602 . A threaded groove, the top of the return frame 8 is threadedly connected with a threaded rod located in the threaded groove, the bottom of the baffle 3 is fixedly connected with a clamping member 10, and the clamping member 10 includes a U-shaped clip that is fixedly connected to the bottom of the baffle 3 Holding the plate, the inner wall of the top of the clamping plate is in contact with the top of the first plate body, the bottom of the clamping plate is threadedly connected with a clamping screw, and the top of the screw is fixedly connected with a clamping block, which is made of rubber. The clamping block is raised to abut against the bottom of the first plate body, thereby further improving the stability of the baffle 3 .

By unscrewing the threaded rod, the return frame 8 can be moved, and the movement of the return frame 8 can drive the support rod 602 and the positioning block 603 to move, so that the positioning block 603 can move back and forth. The rod is screwed into the threaded groove, so that the return frame 8 and the adjustment plate 7 are connected by the threaded rod, thereby facilitating the adjustment of the position of the positioning block 603 for different patients.

Working principle: when the handle is pulled, it can drive the insertion rod 6076 to move, and the movement of the insertion rod 6076 can drive the slide plate 6074 to move along the direction of the fixed rod 6073 and pull the first spring 6075.
