Description

Technical Field

[0001] The utility model relates to the field of interventional surgery tools, in particular to a head support for neuro-interventional surgery. Background Art

[0002] DSA, the full name of which is digital subtraction angiography, is a commonly used medical imaging technology. It uses computer processing technology to digitally subtract the bone, muscle and other tissue backgrounds in the angiography image, thereby highlighting the vascular image so that doctors can better observe the condition of vascular lesions. DSA examinations are often used to diagnose vascular diseases such as arteriosclerosis, vascular stenosis, vascular malformations, etc., as well as to assess the degree and extent of vascular lesions, providing a basis for further treatment. During the operation, a headrest is required to fix the patient's head to prevent the patient from moving his head during the operation due to factors such as unconsciousness, which would affect the image observation under DSA.

[0003] The existing head support structure is a 3 / 4 circular fully enclosed structure that completely surrounds the sides of the patient's head, and then an airbag is used to further fill the gap to fix the patient's head. Since the head support structure is fully enclosed, when the airbag squeezes the head, it is easy to squeeze the ears, causing discomfort such as ear tenderness and numbness after surgery. In addition to the airbags set for the forehead, the airbags set for the face in the existing head support are unstable because they are positioned towards the cheek area. Specifically, the only parts of the human cheek that are raised are the zygomatic bones and mandibles, while the cheek part is fleshy. Therefore, it is difficult to achieve stable fixation of the soft tissue of the cheek part using airbags, and the patient's head can still produce micro-movements, affecting image observation.

[0023] like Figure 1-Figure 4 The headrest for neurointervention surgery shown in the figure comprises cheek pads 1 arranged on the left and right sides of the head and a back head pad 2 connected to each other below the left and right cheek pads 1. Figure 2 and Figure 3 As shown, the cheek pad 1 includes a vertical body 11 extending vertically at the temporal part of the head and a horizontal body 12 extending horizontally at the mandibular part. The upper end of the vertical body 11 is provided with a first arc segment 13 inclined and protruding toward the cheek direction, and the upper end of the horizontal body 12 is provided with a third arc segment 15 protruding toward the middle of the face. A second arc segment 14 extending and concave toward the ear is provided between the first arc segment 13 and the third arc segment 15. The top of the third arc segment 15 is in a blunt arc shape, and the third arc segment 15 is in a pointed arc shape close to the chin. The inside of the cheek pad 1 is filled with sponge or silicone, and the overall softness makes it more comfortable for patients to use. When in use, the patient's auricle can extend from the ear hole 16 surrounded by the second arc segment 14. The ear hole 16 is in a semi-enclosed shape with an upper opening, so as to avoid the cheek pad 1 from causing pressure and discomfort to the patient's ear.

[0024] A groove 17 is provided on the inner side of the upper part of the vertical body 11 and the inner side of the lower part of the horizontal body 12. An airbag 3 is installed in the groove 17. The airbag 3 is inflated and bulges inward to fix the frontal bone and the mandible respectively, so as to prevent the head from rotating and tilting in the left and right directions, and also has a certain blocking effect on the pitch rotation of the head. A circular tube groove for accommodating the ventilation tube of the airbag 3 is provided on the side of the groove 17 to accommodate the ventilation tube of the airbag 3. The ventilation tube is connected to the outside of the ventilation tube to inflate and deflate the airbag 3.

[0026] The cheek pad 1 and the back of the head pad 2 are fixed with a support frame 4. Figure 2 As shown, a vertical plate 401 is provided on the support frame 4 corresponding to the vertical body 11, a horizontal plate 402 is provided at the lower end of the vertical plate 401, a vertical short plate 403 is provided on the horizontal plate 402 corresponding to the mandibular part, a short plate 404 extending in the horizontal chin direction is provided at the upper end of the short plate 403, and a wire slot hole 405 is provided at the top of the vertical plate 401 and the end of the short plate 404; a forehead strap 406 is connected between the wire slot holes 405 of the left and right vertical plates 401; a chin strap 407 is connected between the wire slot holes 405 of the left and right short plates 404. A forehead pad 408 is provided in the middle of the forehead strap 406; a chin support 409 is provided in the middle of the chin strap 407, as shown in FIG. Figure 4 shown.

[0027] The support frame 4 not mentioned in this embodiment includes a bottom bracket 410 supported under the back head pad 2. The support frame 4 is made of a radiation-transmissive material as a whole so as not to affect DSA image observation, and plays a role in supporting and stabilizing the cheek pad 1 and the back head pad 2.

[0028] Hooks 411 are installed on the left and right horizontal plates 402, and the number of hooks 411 on each side is one or two. The hooks 411 can be used to hang and fix other medical tubes carried by the patient, such as oxygen tubes, etc.

[0029] A height adjustment device is vertically connected to the lower part of the support frame 4, and the height of the headrest can be adjusted by the height adjustment device. Figure 1As shown, the height adjustment device includes a vertical cylinder 51 fixed below the support frame 4, an inner sleeve 52 is slidably arranged in the vertical cylinder 51, the lower end of the inner sleeve 52 is fixedly connected to the fork frame 53, and a locking bolt 54 is arranged on the vertical cylinder 51 to rotate and tighten the inner sleeve 52. The locking bolt 54 is threadedly engaged with the vertical cylinder 51, and after adjusting to a suitable height, the locking bolt 54 is tightened, and the locking bolt 54 tightens the inner sleeve 52 to achieve fixation.

[0030] A fork frame 53 is fixed at the bottom of the height adjustment device, and the head support is installed on the operating table through the fork frame 53. There are two forks 53, which correspond to two mounting holes on the operating table respectively, and each fork frame 53 corresponds to a vertical cylinder 51 and an inner sleeve 52.

[0031] In this embodiment, the support frame 4 and the vertical tube 51 are fixed together via a connecting frame 55 .

[0032] When in use, the patient lies supinely on the operating table and the head rest is used to keep the head facing upward. Specifically, the patient's head lies in the head rest, the cheek pads 1 fix the left and right sides of the patient, and the left and right cheek pads 1 are fixed to the patient's head through the forehead strap 406 and the chin strap 407. The patient's auricle can be extended from the second arc segment 14 to avoid being pressed. When the airbag 3 is inflated, the airbag 3 swells and compresses the front side of the patient's frontal bone and the mandible to achieve fixation, which can prevent the patient's head from turning left and right, tilting, and raising or lowering the head.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
