Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a surgical head multimodal positioning fixator. Background Technology

[0002] Surgical head multimodal positioning devices are specialized medical devices used to precisely fix the position of a patient's head. They are mainly used in surgical scenarios such as neurosurgery, ENT, and maxillofacial surgery, where head and neck positioning is critical. Their core function is to ensure the stability of the patient's head during surgery, thereby improving surgical safety and success rates. Head surgeries use local anesthetic drugs, such as topical anesthetics, local infiltration anesthetics, or nerve block anesthetics, to temporarily block nerve conduction in and around the surgical site, thus reducing the patient's local pain sensation during surgery. This surgical method can effectively suppress surgical pain and minimize the impact on the patient's overall physiological functions. Head surgeries require high-precision operation, and the stability of the patient's head and the maintenance of their position are of paramount importance.

[0003] Existing surgical head positioning devices may cause patients' heads to move unconsciously during surgery, leading to head displacement and affecting the precision and safety of the surgical procedure. Utility Model Content

[0005] The technical solution of this utility model is as follows: a surgical head multimodal positioning device, including a pillow support, a headrest woven in the middle of the pillow support, two mounting seats fixed on the side wall of the pillow support, a first electric push rod fixed at the end of each mounting seat, a movable seat fixed at the output end of each first electric push rod, a second electric push rod fixed at the top of each movable seat, a first limiting seat fixed at the output end of each second electric push rod, an arc-shaped connecting rod rotatably connected in the middle of each first limiting seat, a second connecting seat fixed on the side wall of each support belt, a support belt fixed at the top of each movable seat, a first pad woven in the side wall of each support belt, an adjusting belt rotatably connected to the side wall of each support belt near the first pad, a pressure sensor fixed at the end of each adjusting belt, an installation groove opened on the side wall of the pillow support, a control component provided at the bottom of the installation groove, the control component including a circuit board fixed at the bottom of the installation groove, a control chip fixed on the surface of the circuit board, and an input / output module fixed on the surface of the circuit board near the control chip.

[0006] Furthermore, the mounting base, movable base, and support belt are all symmetrically distributed. The movable base is slidably connected to the inner bottom of the mounting base, and the other end of the arc-shaped connecting rod is rotatably connected to the end of the second connecting base, which improves the stability of the support belt movement.

[0007] Furthermore, the first electric actuator, the pressure sensor, and the second electric actuator are symmetrically distributed, and the input / output module is coupled to the first electric actuator, the pressure sensor, and the second electric actuator, respectively.

[0008] Furthermore, pressure gauges are fixed on the side wall of the pillow support near the mounting base, and the pressure gauges are coupled to the input and output modules respectively, which improves the accuracy of pressure control.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, the following are described:

[0023] In head and neck surgery, ensuring the stability of the patient's head is one of the key factors for the success of the surgery. Head and neck surgery requires extremely high precision in the surgical site. Even the slightest movement of the patient's head may interfere with the surgical process, increase surgical risks, and affect the surgical outcome. Surgical head multimodal positioning devices have emerged to address this need. They are specially designed to firmly and comfortably fix the patient's head during the operation, providing a guarantee for the smooth progress of the surgery.

[0024] The main support frame of the head fixation device is the basic structure of the entire device. It is usually made of a sturdy yet lightweight metal material, such as aluminum alloy. It has sufficient strength to withstand the weight of the patient's head and the various forces generated during fixation, without placing excessive burden on the patient. The frame's shape is designed according to ergonomic principles, adapting to the shape and height of the operating table for easy operation by medical staff. It generally includes a bottom support platform and vertically connected support columns. The bottom support platform has a large area to ensure the stability of the device when placed on the operating table and prevent displacement due to external forces during surgery.

[0025] Headrest: The headrest comes into direct contact with the patient's head and is a crucial part of the fixation device. Its design fully considers the physiological curves of the human head and usually uses soft and elastic materials, such as silicone or memory foam, to provide comfortable support. The shape of the headrest can be adjusted according to different age groups and head sizes. Some high-end products also have a customizable function to better fit the patient's head and reduce discomfort caused by prolonged fixation. The surface of the headrest often has ventilation holes to ensure normal breathing of the patient's scalp and reduce sweating and stuffiness.

[0026] Fixation straps: Fixation straps are used to stabilize the patient's head on the headrest. They are generally made of wide, soft, and elastic fabric materials, such as nylon braided straps, which can provide sufficient restraint without causing chafing to the patient's skin. There are usually multiple fixation straps, which fix the head from different directions. Common ones include forehead fixation straps, occiput fixation straps, and fixation straps for both ears. These fixation straps are connected by adjustable buckles or Velcro. Medical staff can flexibly adjust the tightness of the fixation straps according to the size of the patient's head and the needs of the surgery.

[0027] Head adjustment mechanism: In order to meet the specific requirements of different surgeries for the patient's head position, the head fixation component is also equipped with a head adjustment mechanism. This mechanism can achieve fine adjustment of the head support in multiple dimensions, such as forward and backward movement, left and right rotation, and up and down tilt. Common adjustment methods include thread adjustment, gear and rack adjustment, and hydraulic adjustment. Through these adjustment methods, medical staff can accurately adjust the patient's head to the ideal surgical position, ensuring a clear surgical field and convenient operation.

[0028] It primarily operates based on the principles of statics in mechanics. Through the headrest, fixation straps, and various support structures, it applies forces to the patient's head in multiple directions, balancing these forces to achieve stable fixation of the patient's head. For example, the forehead fixation strap and the occipital fixation strap apply tension from the front and back of the head, respectively. The resultant force of these two tensions balances the weight of the head and other external forces that may be generated during the surgery, ensuring that the head does not shift in the front-back direction. The pressure applied to the sides of the head by the side fixation baffles cancels out the external forces that may be applied to the head in the left-right direction, preventing the head from swaying from side to side. The upward support provided by the headrest and neck support pad balances the weight of the head, ensuring that the head remains stable in the vertical direction.

[0029] When using a surgical head fixation device to immobilize a patient's head, it is important to ensure that the tightness of the fixation straps is moderate. If they are too tight, it may cause discomfort to the patient or even damage the skin; if they are too loose, they will not provide effective fixation. First, fix the main fixation straps, such as the forehead fixation strap and the occipital fixation strap. Then, adjust the lateral fixation baffles and ear fixation straps as needed. When adjusting the position and angle of the headrest, proceed slowly and closely observe the patient's reaction to ensure that the adjustment process is safe and comfortable. After fixation is complete, check again whether each fixation component is secure and whether the patient's head is stable.

[0030] During the surgery, medical staff should continuously monitor the fixation of the patient's head, observing whether the fixation device is loose or shifted. If slight movement of the patient's head or abnormality of the fixation device is found, adjustments should be made in a timely manner. At the same time, attention should be paid to observing the patient's facial expressions and physical reactions to determine whether the patient has any discomfort symptoms, and appropriate measures should be taken in a timely manner if necessary.

[0031] Existing surgical head positioning devices may cause patients' heads to move unconsciously during surgery, leading to head displacement and affecting the precision and safety of the surgical procedure.

[0032] Please refer to Figures 1-5A surgical head multimodal positioning device includes a pillow support 1, which is made of stainless steel and is U-shaped for support and positioning. A headrest 6 is woven into the middle of the pillow support 1, and grooves are formed on the surface of the headrest 6 for head engagement.

A support belt 5 is fixed to the top of each movable seat 4. The mounting seats 2, movable seats 4, and support belts 5 are symmetrically distributed. The movable seats 4 are slidably connected to the inner bottom of the mounting seats 2, improving the stability of the support belt 5's movement. The first electric actuator 3 can push the two movable seats 4 to move horizontally, thereby changing the distance between the two support belts 5. The top of each movable seat 4 is fixed with a second electric actuator 12 by bolts. The output end of each second electric actuator 12 is fixed with a first limiting seat 13 by a coupling. An arc-shaped connecting rod 14 is rotatably connected to the middle of each first limiting seat 13. A second connecting seat 15 is fixed to the side wall of each support belt 5 by welding. The other end of the arc-shaped connecting rod 14 is rotatably connected to the end of the second connecting seat 15. Activating the second electric actuator 12 can drive the arc-shaped connecting rod 14 to move upward, thereby pushing the support belt 5 to rotate inward, thus facilitating clamping the patient's head. The side wall of each support belt 5 is woven with a first protective pad 8 to improve the comfort of clamping. Adjustable straps 9 are rotatably connected to the sidewalls near the first pad 8. The adjustable straps 9 are made of silicone and used for support and limiting. Pressure sensors 11 are fixed to the ends of the adjustable straps 9. A mounting groove 7 is provided on the sidewall of the pillow support 1. A control component 10 is located at the bottom of the mounting groove 7. The control component 10 includes a circuit board 1001 fixed to the bottom of the mounting groove 7 to simplify the circuit. A control chip 1002 is fixed to the surface of the circuit board 1001. The control chip 1002 receives, processes, and issues commands. An input / output module 1003 is fixed to the surface of the circuit board 1001 near the control chip 1002. The input / output module 1003 is used to input and output electrical signals. The first electric push rod 3 and pressure sensor 1... The first and second electric push rods 11 and 12 are symmetrically distributed. The input / output module 1003 is coupled to the first electric push rod 3, pressure sensor 11 and second electric push rod 12 respectively. During the operation, when the pressure on one side of pressure sensor 11 is too high, the control chip 1002 can issue a command to finely adjust the first electric push rod 3 and the second electric push rod 12 on the corresponding side, so that the two pressure sensors 11 maintain constant pressure, thereby keeping the patient's head stable and improving the stability of the patient during the operation. This device is especially suitable for patients with mental illness undergoing head and neck maxillofacial surgery under local anesthesia, patients undergoing head and neck maxillofacial surgery without endotracheal intubation and muscle relaxants, patients undergoing head and neck maxillofacial surgery under local anesthesia with Parkinson's disease, and patients undergoing ophthalmic local anesthesia.

[0033] Pressure gauges 21 are fixedly installed on the side wall of the pillow support 1 near the mounting base 2. The pressure gauges 21 are coupled to the input / output module 1003, which improves the accuracy of pressure control. Bone conduction headphones 17 are fitted on the outer surface of the two adjustment belts 9. The bone conduction headphones 17 are coupled to the input / output module 1003. The bone conduction headphones 17 are used to play music to relieve the patient's surgical pressure. Alarms 16 are fixedly installed on the side wall of the two support belts 5 near the second electric push rod 12. The alarms 16 are coupled to the input / output module 1003 to prompt the patient to adjust. The alarm 16 integrates a vibration motor, a buzzer and an LED light. When the pressure sensor 11 is normal, the LED light shows green. When the pressure is too high or too low, the LED light shows red. The alarm 16 is used to sound an alarm to prompt medical staff and the patient to move their head.

[0034] A neck support 18 is fixed on the side wall of the pillow support 1 away from the mounting groove 7.

[0035] When using this surgical head positioning device, medical staff insert the magnetic guide rail 20 into the bed rail and then fix it with bolts. The rail is existing technology and is used for installation and positioning, thereby fixing the pillow support 1. When it is necessary to fix the patient's head for ophthalmic anesthesia surgery, the patient's head is engaged in the middle of the head support 6, so that the patient's neck is supported on the top of the second pad 19. Then, the two first electric push rods 3 are activated to push the movable seat 4 to move towards each other, so that the two support straps 5 support the side wall of the patient's head, and the two pressure sensors 11 are respectively supported at the patient's temples to detect pressure, thereby improving the accuracy and efficiency of the patient's head fixation. Then, the second electric push rod 12 is activated to drive the arc-shaped connecting rod 14 to move upward, thereby pushing the support strap 5 to rotate inward, thereby further improving the stability of the patient's head fixation. During the operation, when The patient's head moves slightly without conscious effort, causing a pressure change on the pressure sensor 11. The detected pressure value is displayed on the pressure gauge 21. The control component 10, pressure sensor 11, and alarm 16 work together to make the alarm 16 sound a buzzer to alert the patient and medical staff that the pressure on this side is too high and the patient's head needs to be slightly turned to the other side for adjustment. This avoids the patient's head displacement from affecting the stability of the head surgery, thereby improving the safety of the surgery. After the surgery is completed, the two first electric push rods 3 and the second electric push rod 12 are driven in opposite directions to release the limit and facilitate the patient's head leaving the device. This device is particularly suitable for patients undergoing head and neck maxillofacial surgery under local anesthesia with mental illness, patients undergoing head and neck maxillofacial surgery without endotracheal intubation and muscle relaxants, patients undergoing head and neck maxillofacial surgery under local anesthesia with Parkinson's disease, and patients undergoing ophthalmic local anesthesia.

[0036] Also taking into account the tension and stress patients experience during surgery, medical staff can play soothing music by activating the bone conduction headphones 17 to calm the patient's mind.
