Detailed implementation mode

[0043] The present invention provides a Figures 1-6 type of head fixation device for neurointerventional surgery as shown, which can fix the patient's head during neurointerventional surgery, avoid the unconscious movement of the non-general anesthesia patient's head, and is convenient for adjusting the inclination of the patient's head, and can solve the influence of the patient's head micro-vibration on DSA imaging.

[0044] The present invention specifically includes four major parts:

[0045] The first part: the support mechanism;

[0046] Referring to Figure 1 as shown, the support mechanism includes a plastic box pillow 1. The height of the plastic box pillow 1 is about 5 cm, and binding straps 9 are arranged on both sides of the plastic box pillow 1. Through the binding straps 9, the plastic box pillow 1 can be tied and fixed on the operating table, so as to be used for the basic support of the head.

[0047] The second part: the fixation mechanism;

[0048] Referring to Figure 1 as shown, the fixation mechanism includes a first airbag 2, a second airbag 3, a third airbag 4, a fourth airbag 5 and a fifth airbag 6. The first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5 and the fifth airbag 6 are all fixedly connected to the upper surface of the plastic box pillow 1.

[0049] Among them, the first airbag 2 is used to support the left temporal region of the head; the first airbag 2 can be inflated or aspirated, so as to adjust the degree of inflation and facilitate the adaptive support of the left temporal region of the head;

[0050] The second airbag 3 is used to support the back of the head; the second airbag 3 can be inflated or deflated to adjust the degree of inflation, facilitating adaptive support for the back of the head.

[0051] The third airbag 4 is used to support the right temporal region of the head; the third airbag 4 can be inflated or deflated to adjust the degree of inflation, facilitating adaptive support for the right temporal region of the head.

[0052] The fourth airbag 5 is used to support the lower part of the neck; the fourth airbag 5 can be inflated or deflated to adjust the degree of inflation, facilitating adaptive support for the lower part of the head's neck.

[0053] The fifth airbag 6 is used to bind the upper part of the neck; the fifth airbag 6 can be inflated or deflated to adjust the degree of inflation, facilitating adaptive support for the upper part of the head's neck.

[0054] The head of the patient is limited and fixed by the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5 and the fifth airbag 6, and can be well fixed. Moreover, by inflating or deflating the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5 and the fifth airbag 6, the tilt angle of the head can be adjusted; it is convenient to adjust according to the surgical needs.

[0055] Specifically, when the first airbag 2 is inflated, due to the inflation of the first airbag 2, the head tilts towards the direction of the third airbag 4, and at the same time, the gas in the third airbag 4 is discharged to avoid excessive compression of the head; similarly, when the second airbag 3 is inflated and the fourth airbag 5 is deflated, the position of the head near the back of the brain can be lifted upward; when the fourth airbag 5 is inflated and the fifth airbag 6 and the second airbag 3 are deflated, the position of the head near the neck can be lifted upward.

[0056] During specific use, it is necessary to control the free rotation range of the head within 45°; the pitching adjustment range is within 30°. Moreover, the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5 and the fifth airbag 6 are all made of silicone material, which does not affect the DSA imaging during the operation, and based on the flexibility of the silicone material, it can automatically adapt to the size and length of the head without additional buckles and other structures for adjustment.

[0057] The heights of the first airbag 2 and the third airbag 4 are both higher than those of the second airbag 3 and the fourth airbag 5, ensuring that the first airbag 2 and the third airbag 4 support on both sides of the head respectively. Moreover, the independent design of the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5 and the fifth airbag 6 replaces the fully enclosed fixing method in the prior art, with good heat dissipation, which can reduce the temperature of the head by about 2 - 3 degrees Celsius, reducing the unstable influence on DSA imaging caused by heat.

[0058] Among them, a buckle groove 8 is further provided on the upper surface of the plastic box pillow 1. There are multiple buckle grooves 8. One end of the fifth airbag 6 is fixedly connected to the upper surface of the plastic box pillow 1, and a clamping block is provided at the other end of the fifth airbag 6. The clamping block can be cooperatively connected to the corresponding buckle groove 8, so that the fifth airbag 6 is pressed above the neck.

[0059] The third part: the adjusting mechanism;

[0060] Refer to Figures 1 to 3 As shown in , the adjusting mechanism includes an air inlet pipe 14 and an air outlet pipe 15. Both the air inlet pipe 14 and the air outlet pipe 15 are communicated with the inside of the plastic box pillow 1. The inside of the plastic box pillow 1 is communicated with the inside of the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5, and the fifth airbag 6. One end of the air inlet pipe 14 far away from the plastic box pillow 1 is connected with a hot air box 16, and a blower pump 17 is provided at the air inlet of the hot air box 16. One end of the air outlet pipe 15 far away from the plastic box pillow 1 is provided with an air extraction pump 18.

[0061] When the blower pump 17 is started, the wind can be sequentially transported through the hot air box 16, the air inlet pipe 14, and the plastic box pillow 1 to the inside of the corresponding first airbag 2, second airbag 3, third airbag 4, fourth airbag 5, and fifth airbag 6; when the air extraction pump 18 is started, the gas inside the first airbag 2, second airbag 3, third airbag 4, fourth airbag 5, and fifth airbag 6 can be sequentially discharged through the plastic box pillow 1 and the air outlet pipe 15, achieving the purpose of controlling the inflation or deflation of the corresponding first airbag 2, second airbag 3, third airbag 4, fourth airbag 5, and fifth airbag 6, facilitating the fixation of the head with appropriate force and being able to adjust the inclination of the head.

[0062] Furthermore, when the gas passes through the hot air box 16, it is heated by an electric heating structure such as an electric heating plate provided inside the hot air box 16, so that the gas entering the first airbag 2, second airbag 3, third airbag 4, fourth airbag 5, and fifth airbag 6 has a certain amount of heat, which is suitable for use in cold weather, making the patient more comfortable, and the body state under non-general anesthesia is easy to remain stable, and it is not easy to appear phenomena such as slight tremors that affect DSA imaging.

[0063] The fourth part: the soothing mechanism;

[0064] Refer to Figures 1 to 5 As shown in , the soothing mechanism includes a water inlet pipe 12 and a water outlet pipe 13. One end of both the water inlet pipe 12 and the water outlet pipe 13 is communicated with the inside of the plastic box pillow 1. One end of the water inlet pipe 12 far away from the plastic box pillow 1 is connected with a water pump 10 and a small water tank 11, and one end of the water outlet pipe 13 far away from the plastic box pillow 1 is also communicated with the small water tank 11; cold water is stored in the small water tank 11; when the water pump 10 is started, the water in the small water tank 11 can be pumped into the inside of the plastic box pillow 1 through the water inlet pipe 12.

[0065] A water retaining strip 19 is provided on the inner bottom surface of the plastic box pillow 1. The height of the water retaining strip 19 is less than the height of the inner space of the plastic box pillow 1. The water retaining strip 19 divides the interior of the plastic box pillow 1 into a soothing water cavity 21 and a conversion air cavity 20. A flow guide plate 22 is provided in the soothing water cavity 21. The flow guide plate 22 is composed of multiple staggered and inclined plates, and the flow guide plate 22 is fixed on the inner wall of the soothing water cavity 21. When cold water enters the interior of the plastic box pillow 1 through the water inlet pipe 12, the cold water can be exactly delivered above the flow guide plate 22, and after flowing through the flow guide plate 22 in multiple stages, it enters the bottom of the soothing water cavity 21. The water at the bottom of the soothing water cavity 21 naturally falls through the water outlet pipe 13 and flows into the small water tank 11 for reuse.

[0066] When water flows through the flow guide plate 22, a water flow sound will be generated, and the water flow sound has a soothing effect on people's psychology, which can keep the human body, especially the head of the human body, stable.

[0067] Furthermore, a temperature sensor 23 for monitoring the temperature is provided on the inner wall of the plastic box pillow 1. When the gas temperature is too high, the electric heating plate in the small water tank 11 can be turned off while the water pump 10 is turned on. At this time, when the gas passes through the interior of the plastic box pillow 1, it just passes horizontally through the flow guide plate 22, which can quickly reduce the temperature of the gas and avoid the influence of too high gas temperature on DSA imaging.

[0068] As an extension, referring to Figures 1 to 6 As shown in, pressure sensing units 24 are provided inside the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5 and the fifth airbag 6. The pressure sensing units 24 can monitor the micro-vibration signals of the head. When the head vibrates slightly, it can cause the pressures inside the corresponding first airbag 2, second airbag 3, third airbag 4, fourth airbag 5 and fifth airbag 6 to change, so as to achieve the purpose of monitoring the micro-vibration signals of the head.

[0069] Multiple inlets and outlets 25 are provided on the plastic box pillow 1. The multiple inlets and outlets 25 are respectively used to connect between the plastic box pillow 1 and the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5, and the fifth airbag 6. A micro-switch valve 26 is provided in the inlet and outlet 25. The micro-switch valve 26 and the pressure sensing unit 24 are connected through a control chip. When the pressure sensing unit 24 monitors a micro-vibration signal of the head, this signal can be fed back to the control chip. The control chip controls the opening of the micro-switch valve 26. At the same time, the control chip is connected to the control ends of the water pump 10, the air supply pump 17, and the air extraction pump 18, and can control the start of the air extraction pump 18 or the air supply pump 17 when the micro-switch valve 26 is opened, so as to achieve the purpose of inflating or inhaling air in the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5, and the fifth airbag 6. The micro-switch valve 26 uses a piezoelectric ceramic proportional valve, and a micro-valve is made of a non-metallic piezoelectric ceramic material. The opening and closing degree is controlled by voltage to achieve millimeter-level precise adjustment of air charging and discharging, and can respond quickly, so as to solve the influence of head micro-vibration on DSA imaging.

[0070] It should be noted that the pressure sensing unit 24 can be made of polyvinylidene fluoride or conductive polymer material to make a micro-pressure sensor for the purpose of real-time monitoring of the head micro-vibration signal. In actual use, the pressure sensing unit 24 can also be embedded in the outer surface of the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5, or the fifth airbag 6 to contact the head and achieve more accurate monitoring.

[0071] In the present invention, it is also considered that the air permeability of the silicone material attached to the head is poor. Therefore, a cotton cloth 7 is also provided on the outer surface of the plastic box pillow 1, the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5, or the fifth airbag 6. The cotton cloth 7 contacts the head, is soft and comfortable, and has good air permeability.

[0072] It should be further noted that a support skeleton can also be printed on the inner wall structure of the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5, and the fifth airbag 6 by using 3D printing technology to ensure the basic shape of the first airbag 2, the second airbag 3, the third airbag 4, the fourth airbag 5, and the fifth airbag 6. The skeleton can use a skeleton with a certain flexibility, and a suitable material can be selected according to actual needs.
