Description

Technical Field

[0001] The utility model relates to the technical field of surgical adjustment, in particular to a head adjustment device for surgery. Background Art

[0002] The surgical head adjustment device is a medical device used to fix the patient's head during surgery to ensure the accuracy and safety of the surgical operation. Many head surgeries require adjustment of the patient's head, such as trigeminal neuralgia, which is a common severe painful disease. For details, see the "Chinese Expert Consensus on Percutaneous Balloon Compression of the Trigeminal Ganglion". Currently, percutaneous balloon compression (PBC) is one of the main surgical procedures for the treatment of trigeminal neuralgia. Percutaneous balloon compression is a minimally invasive surgery. During the operation, many details such as the use of navigation equipment, the selection of puncture positioning auxiliary tools, and the placement of the head during surgery are constantly being discussed and improved.

[0003] In the prior art, the placement of the head in clinical work is mostly based on experience and habit. However, in actual operation, due to the need for navigation positioning and the convenience and reliability of the puncture angle, a cushion is often placed under the occipital region. The materials used vary in hardness and softness, such as a softer folding surgical towel and a tougher infusion bottle, and are mostly made from local materials. Another commonly used method is to place the patient's head on an adjustable plate at the head end of the operating bed, and tilt the plate downward to achieve a state where the head is slightly tilted back. However, both of the above methods have corresponding problems. The disadvantage of a one-time cushion is that it is difficult to make a secondary adjustment to the head position during the operation, and it lacks flexibility. The adjustment plate at the head end of the operating bed is a step-by-step adjustment, and the angle produced by each step of adjustment is relatively large, which cannot be effectively applied to the fine-tuning requirements of the height within a small local range required in the operation. There are many difficulties in the operation during the operation, and even the angle of the head tilting back needs to be readjusted. Utility Model Content

[0004] In order to solve the above technical problems, the utility model uses an adjusting rotary rod to adjust the height of the scissors, so as to achieve a more precise micro-adjustment of the neck and pillow within a small range. The specific technical solution is as follows:

[0005] A surgical head adjustment device comprises a headrest, which comprises a neck pillow portion for supporting the neck position of the head; and an adjustment member for adjusting the height of the neck pillow portion, wherein the adjustment member comprises a scissor fork arranged at the neck pillow portion, a scissor fork rod rotatably mounted on the end of the scissor fork, and an adjustment rotary rod for driving the distance between a pair of the scissor fork rods and driving the height of the scissor fork to rise and fall.

[0006] Preferably, the headrest further comprises a shoulder rest portion and a head rest portion which are arranged on both sides of the neck rest portion and fit the shoulders and the back of the head respectively.

[0007] Preferably, the adjusting member further comprises a top plate arranged at the top end of the scissors fork, and the top plate supports the neck pillow portion.

[0008] Preferably, the number of the adjusting members is plural, and the adjusting rotary rod drives the scissor rods of multiple pairs of adjusting members.

[0009] Preferably, the plurality of top plates are fixedly mounted with a same support block for lifting the neck pillow portion.

[0010] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0011] By setting an adjustment piece, the cervical pillow can fit the patient's neck. By twisting the adjustment rod, the distance between the pair of scissor rods can be driven closer to each other, thereby driving the height of the scissors to be raised, so as to lift the height of the cervical pillow. The angle of the patient's head tilting back can be adjusted more finely, making the operation more convenient.

[0012] The clamp rod is manually adjusted to move to both sides of the head. The other end of the clamp rod is located on the headrest. When the head is deflected, the head presses on the clamp rod, and the end of the clamp rod rests on the headrest to relieve the pressure of the head on the clamp rod. The clamp rod prevents the head from rotating. Combined with the use of the adjustment part, the patient's head can be stably adjusted, which is convenient for medical staff to adjust the patient's head during surgery.
