[0001] The present invention belongs to the technical field of medical auxiliary devices, and particularly relates to a head support and positioning device for neurosurgery. Background Art

[0002] Neurosurgical operations often involve critical parts such as the brain and spinal cord, with a narrow operating space and dense nerves and blood vessels. For example, in brain tumor resection surgery, in order to accurately remove the tumor and maximize the protection of the surrounding normal brain tissue, it is necessary to fix the patient's head in a specific position to fully expose and keep stable the surgical area, and the head support and positioning device came into being to meet the high requirements for accuracy in the surgery.

[0003] During the use of the existing devices for supporting and positioning the patient's head, the position is fixed. However, during the surgical treatment process, it is necessary to adjust the angle and position of the patient's head according to the needs of the treatment. When the patient's head cannot be adjusted, it will affect the exposure of the surgical field and is not conducive to maintaining the patient's physiological state. Summary of the Invention

Detailed implementation manners

[0026] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] The following will, with reference to the drawings, elaborate on the technical solutions provided by various embodiments of the present invention for a neurosurgical head support and positioning device.

[0028] Refer to Figures 1 to 7 As shown, an embodiment of the present invention provides a neurosurgical head support and positioning device, including a support bed 1, an angle change structure 2, a head support seat 3, a head fixation structure 4, and a shoulder adjustment structure 5. The support bed 1 is horizontally arranged. The angle change structure 2 is located at one end of the support bed 1 and is slidably engaged with the support bed 1. The head support seat 3 is located at the top of the angle change structure 2. The head fixation structure 4 is arranged in the head support seat 3 to support and limit the head of the patient. The shoulder adjustment structure 5 is arranged in the head support seat 3 and is slidably engaged with the head support seat 3.

[0029] Specifically, an installation groove 11 is provided at the end of the support bed 1. The angle change structure 2 is located in the installation groove 11. A circular soft protection sleeve 12 is provided between the support bed 1 and the head support seat 3.

[0030] During the process of adjusting the angle of the head support seat 3, the circular soft protection sleeve 12 is squeezed. When being squeezed, the circular soft protection sleeve 12 can contract to facilitate the adjustment of the angular position of the head support seat 3.

[0031] Specifically, the angle change structure 2 includes a support plate 201, a support frame 202, two sliding rods 203, and two lifting rack bars 204. The support plate 201 is horizontally arranged in the installation groove 11. The two sliding rods 203 are symmetrically arranged at the bottom of the support frame 202. The two lifting rack bars 204 are symmetrically arranged on the support frame 202. Both the sliding rods 203 and the lifting rack bars 204 are slidably engaged with the support plate 201. An elevating motor 205 is provided at the position of each lifting rack bar 204. An elevating gear 206 is provided on the main shaft of the elevating motor 205. The elevating gear 206 meshes with the lifting rack bar 204.

[0032] During use, the two lifting motors 205 work synchronously to drive the two lifting gears 206 to rotate on the two lifting racks 204 respectively, thereby driving the two lifting racks 204 to move upward on the support plate 201. When performing an operation on a patient, the height position of the patient's head can be adjusted upward. It can be adjusted according to the different height positions of the head support seat 3, so that the patient is in an optimal surgical position;

[0033] Improve cerebral blood circulation: Raising the head can make the head position higher than the heart level. With the help of gravity, it promotes the venous blood of the brain to flow back to the heart. This helps to maintain normal blood circulation in the brain, ensure the oxygen supply and nutrient supply of brain tissue, and at the same time promptly remove metabolic wastes, reducing brain tissue hypoxia and metabolic disorders caused by blood stasis.

[0034] Reduce venous pressure: It can effectively reduce the pressure of the cerebral venous system and prevent excessive venous filling. For some brain diseases caused by venous reflux disorders, such as operations for cerebral venous sinus thrombosis, raising the head can improve the venous reflux condition, reduce venous pressure, and contribute to surgical operation and the patient's postoperative recovery.

[0035] Specifically, the angle change structure 2 further includes a large arc plate 21, a small arc plate 22, a first motor 23, a second motor 24, a ball seat 25, a universal ball 26 and a swing rod 27. The two ends of the large arc plate 21 are rotatably connected to the support frame 202, the small arc plate 22 is rotatably connected to the support frame 202, the large arc plate 21 and the small arc plate 22 are vertically arranged, the large arc plate 21 and the small arc plate 22 are respectively provided with a large arc groove 211 and a small arc groove 221, the ball seat 25 is located on the support frame 202, the universal ball 26 is rotatably connected to the ball seat 25, the bottom of the swing rod 27 is fixedly connected to the universal ball 26, the swing rod 27 passes through the large arc groove 211 and the small arc groove 221, and the top of the swing rod 27 is provided with a mounting plate 28.

[0036] When the angle of the patient's head changes, the first motor 23 operates to drive the large arc plate 21 to swing on the support frame 202, which will cause the swing rod 27 to rotate on the ball seat 25 through the universal ball 26. As a result, the swing rod 27 swings in the small arc groove 221, causing the angle of the head support seat 3 to change. When the second motor 24 operates to drive the small arc plate 22 to swing on the support plate 201, the swing rod 27 will rotate on the ball seat 25 through the universal ball 26, so that the swing rod 27 swings in the large arc groove 211 to drive the angular position of the head support seat 3 to swing. The swing of the angular position of the head support seat 3 will cause the position of the patient's head to be adjusted.

[0037] Better expose the surgical area: Different neurosurgical operations require exposing different brain regions. For example, during skull base tumor surgery, by adjusting the head angle, the skull base structure can be better exposed in the surgical field of view, facilitating the doctor to clearly observe the relationship between the tumor and important structures such as surrounding nerves and blood vessels, which is conducive to more precisely removing the tumor and reducing damage to normal tissues.

[0038] Provide the best surgical operation angle: A suitable head angle can provide an ideal operation angle for the surgeon, making it easier for surgical instruments to reach the lesion site and the operation more smooth. Taking cerebrovascular surgery as an example, adjusting the head angle can make the blood vessel direction more conducive to surgical operation, facilitating the doctor to perform operations such as blood vessel anastomosis and clamping, and improving the success rate of the operation.

[0039] Reduce visual occlusion: Reasonable adjustment of the head angle can avoid the occlusion of the surgical field of view by structures such as brain tissue and skull. In deep brain tumor surgery, if the head angle is inappropriate, the surrounding brain tissue may cover the tumor, affecting the doctor's judgment of the tumor boundary and operation. By adjusting the angle, these occlusions can be eliminated, allowing the doctor to observe the surgical area more comprehensively and ensuring the accuracy of the operation.

[0040] Specifically, the head support seat 3 is connected to the mounting plate 28, the mounting plate 28 is located above the annular soft protective sleeve 12, and the head support seat 3 is provided with a placement groove for placing the patient's head; the head fixing structure 4 includes an air cushion 41 that fits in the placement groove. The air cushions 41 are five in number, and each air cushion 41 is provided with an air nozzle 42, and the air nozzle 42 is located on the head support seat 3.

[0041] After the air cushions 41 are divided into five pieces and the patient's head is placed in the placement groove, air can be inflated into the corresponding air nozzles 42 as needed. After inflation, the corresponding air cushions 41 will inflate and expand, thus limiting the position of the patient's head in the placement groove. During the surgical treatment process, the position of the patient's head will not shake and affect the accuracy of the treatment.

[0042] Specifically, the shoulder adjustment structure 5 includes a horizontally arranged sliding plate 51 which is slidably connected within the mounting plate 28. Locking bolts 52 for locking the sliding plate 51 are provided at both ends of the mounting plate 28. Two upper mounting grooves are provided at the top of the sliding plate 51. An adjusting plate 53 is rotatably connected within each upper mounting groove. An extension plate 54 which is slidably engaged with the adjusting plate 53 is provided on the adjusting plate 53. A shoulder rest 55 is provided at the top of the extension plate 54. A number of equally spaced insertion holes 56 are provided on the extension plate 54. A pin 57 which is inserted into and engaged with the insertion holes 56 is provided on the sliding plate 51. Two lower mounting grooves are provided at the bottom of the sliding plate 51. A support hydraulic rod 58 is provided within each lower mounting groove. The support hydraulic rod 58 is rotatably connected to the lower mounting groove.

[0043] When performing surgical treatment on a patient's head, loosen the two locking bolts 52, then pull the sliding plate 51 outwards from the mounting plate 28. Rotate the two support hydraulic rods 58 from a horizontal state to a vertical state within the lower mounting grooves, and support the position of the sliding plate 51 through the two support hydraulic rods 58. Then adjust the two adjusting plates 53 from a horizontal state to a vertical state, so that the positions of the two shoulder rests 55 move to the patient's shoulders to support the patient's shoulders. During the support process, according to the different body positions of the patient, move the extension plate 54 upwards from the adjusting plate 53, and insert the pin 57 into the corresponding insertion hole 56, thereby realizing the fixation of the positions of the extension plate 54 and the adjusting plate 53.

[0044] When positioning and supporting the head in neurosurgery, adjust the height of the patient's shoulders.

[0045] Maintain airway patency: Appropriately elevating the shoulders can cause the patient's neck to extend naturally, reduce the distortion and compression of the airway, and is beneficial to maintaining airway patency. Especially for obese patients or patients with short and thick necks, this effect is more obvious. During the operation, it can ensure smooth breathing and reduce the risks such as hypoxia and carbon dioxide retention caused by airway obstruction.

[0046] Promote pulmonary ventilation: Adjusting the shoulder height can change the position and shape of the chest cavity, enable the chest cavity to expand and contract better, thereby promoting the pulmonary ventilation function, improving the gas exchange efficiency, ensuring that the patient has sufficient oxygen supply during the operation, and maintaining the normal respiratory physiological state.

[0047] Facilitate head exposure: Adjusting the shoulder height can assist in adjusting the angle and position of the head, making the head better expose the surgical area. For example, when performing skull base or occipital surgery, appropriately elevating the shoulders can make the head tilt backwards at a more appropriate angle, enabling the surgeon to observe and operate on the surgical site more clearly, which is beneficial to the smooth progress of the operation.

[0048] Reduce tissue occlusion: An appropriate shoulder height can relatively change the position of the neck and surrounding tissues, reducing the occlusion of the surgical area. Taking brainstem surgery as an example, by adjusting the shoulder height, tissues such as neck muscles can be relaxed and moved downward, avoiding their occlusion of the surgical field, providing a broader space for surgical operations, and improving the accuracy of the surgery.

[0049] The above are only examples of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
