Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a head support device for an operating bed which is convenient to adjust. Background Art

[0002] In surgical clinical operations, some operations often need the patient to take the prone position, such as posterior exposure surgery of the cervical vertebra, lumbar spine and back surgery, etc. In the prone position surgery of the patient, a headrest is usually arranged below the head position of the patient to support and limit the head or face, which is convenient for the patient to breathe and connect an oxygen tube or an intubation externally.

[0003] At present, during the operation preparation process, the distance between the headrest and the operating bed needs to be adjusted so that the shoulders of the patient can firmly fall on the operating bed and the head can naturally rest on the headrest, avoiding the shoulder of the patient being empty and not overstretching the neck and head of the patient, ensuring the comfort and safety of the patient. However, the existing prone position headrest often only clamps or fixes at the head position of the operating bed, resulting in inconvenient adjustment of the distance between it and the operating bed.

[0004] Secondly, for posterior cervical and lumbar spine surgeries, it is often necessary to tilt the patient's head forward so that the cervical vertebra or lumbar spine is in a straight position. Since the cervical vertebra and lumbar spine are both physiologically lordotic in the natural state, therefore, in order to fully expose the surgical field, it is necessary to adjust the head elevation angle to make the cervical vertebra and lumbar spine in a straight position to expand the doctor's surgical field and facilitate the operation. However, the existing prone position headrest often cannot assist in adjusting the head elevation angle of the patient, prolonging the operation preparation time and reducing the surgical field, which is not conducive to the doctor's operation, making the practicality of the existing headrest in the operation poor.

[0005] In summary, there is an urgent need to design a head support device for an operating bed which is convenient to adjust and overcomes the above problems. Content of the Utility Model

It should be noted that the fixing frame 13 is preferably a hollow square fixing frame welded by four steel frames. On the one hand, it does not affect the structure of the spacing adjustment mechanism 2. On the other hand, the lower end of the headrest 3 is hollowed out, which is convenient for the anesthesiologist to suction sputum for the patient from under the headrest 3.

[0056] Preferably, a first fastening bolt 14 is inserted through the lower end of the first U-shaped clamp 11 on the side away from the fixed seat 12. The first U-shaped clamp 11 is gradually clamped on both sides of the operating table fixing column from one end of the operating table headboard, and the first fastening bolt 14 is tightened so that the top end of the first fastening bolt 14 presses against the fixing column, then the fixing is completed.

[0057] Preferably, as Figure 4 shown, a cavity 421 is provided inside the upper end of the support column 42. The left and right side walls of the upper end inside the cavity 421 are rotatably connected to a first rotating shaft 44. One end of the first rotating shaft 44 close to the headrest 3 passes through the support column 42 and is fixedly connected to the headrest connecting rod 43;

[0058] The angle adjustment mechanism 5 includes a first gear 51 fixedly sleeved on the first rotating shaft 44 and a second gear 52 provided in the cavity 421 and meshing with the first gear 51. The second gear 52 is rotatably connected to the left and right side walls of the cavity 421 through a second rotating shaft 53. One end of the second rotating shaft 53 away from the headrest 3 passes through the support column 42 and is connected to a second hand crank 54.

[0059] In this embodiment, by rotating the second hand crank 54 to drive the first gear 51 to rotate, the first gear 51 can drive the second gear 52 to rotate, and the second gear 52 can drive the second rotating shaft 53 to rotate, so that the headrest connecting rod 43 and the headrest 3 rotate together, realizing the adjustment of the elevation angle of the patient's head. The gear transmission adjustment is more stable and accurate, can achieve fine adjustment, not only has strong practicability and greatly improves the surgical accuracy, but also can protect the patient's cervical spine from being injured.

[0060] In order to conveniently adjust the height of the patient's head during the operation, the support column 42 is a telescopic rod, which is sleeved by two sections of sleeves, and a positioning bolt 422 is inserted through the side wall of the upper end of the outer sleeve.

[0061] Preferably, a locking mechanism 6 is provided between the first hand crank 24 and the fixed seat 12 and between the second hand crank 54 and the support column 42.

[0062] Preferably, the locking mechanism 6 includes sleeves 61 respectively fixed on the side walls of the first hand crank 24 and the second hand crank 54, a pull rod 62 slidably inserted into the sleeve 61, and tooth blocks 63 and pull rings 64 respectively provided at both ends of the pull rod 62. Annular racks 65 are provided on the side walls of the fixed seat 12 and the support column 42. The center of the annular rack 65 coincides with the axes of the first hand crank 24 and the second hand crank 54, and the tooth block 63 meshes with the annular rack 65;

[0063] A spring 66 is provided inside the sleeve 61. The spring 66 is sleeved on the outer wall of the pull rod 62, and its two ends are fixedly connected to the inside of the sleeve 61 and the tooth block 63 respectively.

[0064] In this embodiment, when it is necessary to rotate the first hand crank 24 and the second hand crank 54, one index finger (or other finger) hooks the pull ring 64 and pulls the pull ring 64 outwards. At this time, the pull rod 62 moves outwards, so that the tooth block 63 disengages from the annular rack 65, and the spring 66 is compressed. At the same time, the palm of this hand holds the first hand crank 24 or the second hand crank 54, and the first hand crank 24 or the second hand crank 54 can be rotated until the position of the headrest meets the surgical requirements, and then the rotation is stopped. At this time, the finger hooking the pull ring 64 can be released, and then the tooth block 63 resets under the elastic force of the spring 66, and it meshes with the annular rack 65 again to achieve locking.

[0065] Preferably, the headrest connecting rod 43 is Z-shaped.

The second C-shaped clamp 41 gradually clamps into both sides of the fixing frame 13 from the front end of the fixing frame 13, and the second fastening bolt 45 is tightened, so that the top end of the second fastening bolt 45 presses against the fixing frame 13, and then the fixing is completed. At the same time, it is also convenient to disassemble when not in use. The second C-shaped clamp 41, the headrest 3 and the headrest support device 4 are integrally disassembled from the fixing frame 13, and most of the fixing frame 13 can be slid to the lower end of the operating bed. When the headrest 3 is not needed for a long time, the first C-shaped clamp 11, the fixing device 1, the headrest 3 and the headrest support device 4 can also be integrally disassembled.

[0068] Preferably, the head support 3 includes a head support seat 32 connected to the head support connecting rod 43 and a support pad 33 arranged at the upper end of the head support seat 32. The surface of the support pad 33 is a silicone pad layer, which fits better with human skin and makes the patient's face more comfortable. A sponge pad with a slightly higher hardness is arranged inside the support pad 33 to improve the support performance. A through hole 34 is provided on the head support 3 to expose the eyes, nose and mouth. A notch 35 communicating with the through hole 34 is provided on the side of the head support 3 close to the operating table. The width of the notch 35 is approximately 3 cm, which is convenient for the patient's tracheal intubation to pass through and avoid squeezing the intubation. The support pad 33 in this embodiment can be set to multiple different models, preferably three. The size of each model of the support pad 33 and the size of the through hole 34 are different, so as to be suitable for patients of different ages or different face sizes.
