Description

Technical Field

[0001] The utility model relates to the technical field of neurosurgical nursing, and more specifically, it relates to a head fixation nursing device. Background Art

[0002] Neurosurgery is a branch of surgery. Based on surgery as the main treatment method, it applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related affiliated institutions, such as the skull, scalp, cerebrovascular meninges, etc. for injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or functional disorders. After surgery or treatment, neurosurgical patients often need to use a head fixation device to fix the patient's head for nursing. However, when using existing related devices to fix the patient's head, the operation process is relatively cumbersome. To solve the above problems, we have introduced the following device. Content of the Utility Model

[0026] Embodiment:

[0027] The following is further described in detail with reference to the attached Figures 1-4 for the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: a head fixation nursing device, including an adjustment plate 1 and a long groove 2. The long groove 2 is opened on the surface of the adjustment plate 1. A long shaft 3 is fixedly connected to the inner wall of the long groove 2. A sleeve 4 is sleeved on the surface of the long shaft 3. A main bed plate 5 is fixedly connected to the surface of the sleeve 4. A transmission groove 6 is opened on the surface of the adjustment plate 1. A first rotating shaft 7 is fixedly connected to the inner wall of the transmission groove 6 through a bearing. One end of the first rotating shaft 7 is fixedly connected to a first knob 8. The other end of the first rotating shaft 7 is fixedly connected to a threaded column 9. The other end of the threaded column 9 is fixedly connected to another group of threaded columns 9. The other end of the other group of threaded columns 9 is fixedly connected to a second rotating shaft 10. The other end of the second rotating shaft 10 is fixedly connected to the inner wall of the transmission groove 6 through a bearing. A threaded tube 11 is threadedly connected to the surface of the threaded column 9. A movable block 12 is fixedly connected to the surface of the threaded tube 11. A chute 13 is opened on the inner wall of the transmission groove 6. A slider 14 is slidably connected in the chute 13. The slider 14 is fixedly connected to the surface of the movable block 12. A support plate 15 is fixedly connected to the upper surface of the movable block 12. An extension rod 16 is fixedly connected to the surface of the support plate 15. A rubber pad 17 is fixedly connected to the other end of the extension rod 16. A headrest 18 is fixedly connected to the upper surface of the adjustment plate 1.

[0029] By adopting the above technical solution, for the head fixation nursing device, when fixing the patient's head, the patient first sits on the main bed plate 5 and then lies down, so that the head is placed on the headrest 18. Then people adjust the first knob 8, which drives the first rotating shaft 7 and the two groups of threaded columns 9 to rotate. Under the mutual cooperation of the threaded column 9 and the threaded tube 11, the two groups of threaded tubes 11 approach each other. Thus, the two groups of threaded tubes 11 drive the corresponding support plates 15, extension rods 16 and rubber pads 17 to move respectively until the two rubber pads 17 are simultaneously close to the patient's head, thereby fixing the patient's head. The fixing process only requires turning the adjustment knob, which facilitates people to quickly fix the patient's head.

[0030] Specifically, a U-shaped frame 19 is fixedly connected to the surface of the main bed board 5. A third rotating shaft 20 is fixedly connected to the surface of the U-shaped frame 19 through a bearing. A second knob 21 is fixedly connected to the lower end of the third rotating shaft 20. A worm 22 is fixedly connected to the upper end of the third rotating shaft 20. A fourth rotating shaft 23 is fixedly connected to the upper end of the worm 22. The upper end of the fourth rotating shaft 23 is fixedly connected to the inner wall of the U-shaped frame 19 through a bearing. A fixing rod 24 is fixedly connected to the surface of the adjusting plate 1. The other end of the fixing rod 24 is fixedly connected to a worm gear 25. The worm gear 25 meshes with the worm 22.

[0031] By adopting the above technical solution, in this head fixation nursing device, by setting the second knob 21, the worm 22 and the worm gear 25, when adjusting the angle of the adjusting plate 1, people rotate the second knob 21, thereby driving the third rotating shaft 20 and the worm 22 to rotate. Under the mutual cooperation of the worm 22 and the worm gear 25, the worm gear 25 rotates, thereby driving the adjusting plate 1 to rotate around the long shaft 3 as the rotation center until the adjusting plate 1 is adjusted to an appropriate angle. Moreover, the mutual cooperation of the worm gear 25 and the worm 22 has a self-locking effect on the worm gear 25, thereby restricting the further rotation of the adjusting plate 1, which facilitates people to adjust the angle of the adjusting plate 1.

[0032] Specifically, the thread directions of the two sets of threaded columns 9 are opposite.

[0033] Specifically, there are two sets of sliding grooves 13 and sliding blocks 14, and they are symmetrically arranged on the side of the movable block 12.

[0034] Specifically, the worm gear 25 is collinear with the center of the long shaft 3.

[0035] Specifically, a support frame 26 is fixedly connected to the bottom of the main bed board 5.

[0036] Specifically, a wheel set 27 is fixedly connected to the bottom of the support frame 26. A brake pad 28 is arranged on the side of the wheel set 27. There are four sets of the wheel set 27 and the brake pads 28, and they are arranged in a rectangular pattern at the bottom of the support frame 26.

[0037] The working principle of the present utility model is as follows: during use, due to the presence of the wheel set 27, people can easily move the device. After moving the device to an appropriate position, people toggle all the brake pads 28 to the braking state. Then, the patient sits on the main bed board 5 and lies down, with the head resting on the headrest 18. Then, people adjust the first knob 8, which drives the first rotating shaft 7 and the two sets of threaded columns 9 to rotate. Under the mutual cooperation of the threaded columns 9 and the threaded tubes 11, the two sets of threaded tubes 11 approach each other. Thus, the two sets of threaded tubes 11 drive the corresponding support plates 15, extension rods 16, and rubber pads 17 to move respectively until the two rubber pads 17 simultaneously abut against the patient's head, thereby fixing the patient's head. When the angle of the adjusting plate 1 needs to be adjusted, people rotate the second knob 21, which drives the third rotating shaft 20 and the worm 22 to rotate. Under the mutual cooperation of the worm 22 and the worm wheel 25, the worm wheel 25 rotates, driving the adjusting plate 1 to rotate around the long shaft 3 as the rotation center until the adjusting plate 1 is adjusted to an appropriate angle. Moreover, the mutual cooperation between the worm wheel 25 and the worm 22 has a self-locking effect on the worm wheel 25, restricting the further rotation of the adjusting plate 1, thereby adjusting the angle of the adjusting plate 1.

[0038] This specific embodiment is only an explanation of the present utility model and does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
