Description

Technical Field

[0001] This utility model relates to the field of surgical head frame technology, specifically a surgical head frame that facilitates head fixation. Background Technology

[0002] A surgical headrest is a medical device used to stabilize a patient's head during surgery. It typically consists of a base, support rods, and a headrest. The base is fixed to the operating table, the support rods are adjustable in height and angle, and the headrest is made of soft material to increase patient comfort. Some models also include head pins for a more secure fixation. It prevents the patient's head from moving during surgery, providing the surgeon with accurate head positioning and a stable surgical field of vision, thus improving surgical precision and safety. Based on structure, it can be classified into three-point and U-shaped types, and based on material, it can be classified into aluminum alloy, carbon fiber, and other materials. It is widely used in neurosurgery, oral surgery, cervical spine surgery, and other fields.

[0003] For example, Chinese authorized patent CN210205258U describes a surgical head frame, which includes a headrest. The bottom end of the headrest is connected to a turntable via a connecting rod. Two opposing and spaced fixed discs are fixed on the bed. The turntable is located between the two fixed discs. A rotating shaft passes through the center of the turntable. The turntable is rotatably connected to the two fixed discs via the rotating shaft. A first adjusting bolt capable of applying pressure to the turntable is provided on one of the fixed discs.

[0004] While the existing surgical head frames mentioned above achieve the limitation and angle adjustment of the patient's head by setting a headrest, the adjustment method is relatively cumbersome. It is necessary to first determine the required posture of the headrest based on the patient, and only after the posture is adjusted can the patient's head be placed on the headrest. Therefore, when the angle of the patient's head needs to be adjusted during the operation, additional medical staff are required to provide auxiliary support for the patient's head, which brings inconvenience to the operation process. Therefore, it does not meet the current needs. In this regard, we propose a surgical head frame that is easier to fix the head. Utility Model Content

[0005] The purpose of this invention is to provide a surgical head frame that facilitates head fixation, thereby solving the problems of poor adjustability and inadequate head support stability of surgical head frames mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surgical head frame for easy head fixation, comprising a base, a groove adapted to the shape of the base on the upper surface near the end of the operating table, the base being fixedly installed in the groove, a movable groove on the upper surface of the base away from the end of the operating table, an adjustable seat rotatably installed in the movable groove, the movable groove providing rotational space for the adjustable seat within a fixed angle range, and the adjustable seat rotating and self-locking about the center of the adjustable seat as the origin through a transmission mechanism, a head positioning frame being installed at the top of the adjustable seat, the head positioning frame being welded and fixed to the adjustable seat, and the head positioning frame being located on the upper surface of the base, the head positioning frame having a head support mechanism for providing different support forces to different areas of the patient's head.

[0007] Preferably, the head support mechanism includes multiple elongated airbags, which are evenly distributed on the inner surface of the head positioning frame. The bottom of the airbags is adhered and fixed to the head positioning frame. Multiple air supply branches are installed on the end of each airbag near the end of the operating table. Each air supply branch is sequentially and spaced with a pressure sensor and an electric control valve.

[0008] Preferably, the head support mechanism further includes an air source box, which is fixedly installed on the side of the operating table near the front end of the base. The air source box contains a microcontroller and an air pump. The air pump's outlet end is equipped with a main air supply pipe, and multiple branch air supply pipes are connected to the main air supply pipe. The output end of the air pressure sensor is connected to the input end of the microcontroller, and the output end of the microcontroller is connected to the electronic control valve and the air pump respectively.

[0009] Preferably, the transmission mechanism includes a transmission rod, and a through notch flush with the bottom surface of the movable groove is provided at one end of the base near the movable groove. The transmission rod is parallel to the upper surface of the through notch, and one end of the transmission rod passes through the adjusting seat laterally and is fixedly connected to it. A worm wheel is fixedly provided at the other end of the transmission rod, and a worm is installed on one side of the worm wheel. The lower end of the worm is rotatably connected to the base, and the worm and the worm wheel are threaded together.

[0010] Preferably, the upper end of the worm gear is provided with a fixedly installed handwheel.

[0011] Preferably, the base is embedded and connected to the groove at the front end of the operating table.

[0012] Preferably, the surfaces of the plurality of airbags are all covered with nonwoven fabric.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a rotating adjustable seat on the base, allowing medical personnel to easily rotate the head positioning frame, which is fixedly connected to the adjustable seat, within a fixed angle range via a transmission mechanism. After the patient's head is placed in the head positioning frame and positioned by multiple airbags, medical personnel can perform surgical procedures. When adjustments to the patient's head are needed, medical personnel can rotate a handwheel to drive a worm gear. The contact surface between the worm gear and the worm wheel forms a spiral friction transmission surface. The rotation of the worm gear drives the worm wheel, which in turn drives the transmission rod. Since one end of the transmission rod is connected to the adjustable seat at the bottom of the head positioning frame, the angle of the head positioning frame can be adjusted via the adjustable seat, thus achieving fine-tuning of the patient's head position. This ensures the surgical site is exposed at the optimal angle in the surgical field, improving the accuracy and success rate of the surgery. It can quickly adapt to diverse surgical needs, providing strong support for the smooth conduct of surgery. Compared to traditional fixed head frames, it significantly reduces the time and effort spent adjusting the patient's head position, allowing medical personnel to focus more on the surgical procedure itself and improving surgical efficiency.

[0015] 2. This utility model, through its head support mechanism and independently designed airbags coupled with independent pressure sensors, enables precise positioning of the patient's head at multiple locations. Since different patients have different head sizes and shapes, this system can monitor the pressure of each airbag in real time via the pressure sensors and automatically adjust the inflation state of each airbag to adapt to the specific shape of each patient's head. This ensures that the head position remains stable and accurate throughout the surgery, providing a reliable guarantee for the smooth progress of the procedure. Compared to complex mechanical fixation structures, the airbag positioning system has a relatively simple structure, reducing gaps and hard-to-clean areas. Before and after surgery, it is easier to clean and disinfect the airbags and related components, effectively reducing the risk of cross-infection and ensuring patient safety.

[0016] 3. The surgical headrest of this invention can be flexibly embedded into the operating table, with its base flush with the operating table. This avoids the extra space occupied by traditional external headrests, making the surgical area more neat and orderly, and facilitating the free movement and operation of various instruments by medical staff during surgery. At the same time, the flush design allows for a more natural and smooth transition between the patient's body and the operating table when lying down, preventing discomfort caused by a protruding headrest and further enhancing the patient experience.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 The present invention provides an embodiment of a surgical head frame for easy fixation of the head, comprising a base 1, a groove adapted to the shape of the base 1 on the upper surface near the end of the operating table 4, the base 1 being fixedly installed in the groove, a movable groove 12 on the upper surface of the base 1 away from the end of the operating table, an adjustable seat 13 rotatably installed in the movable groove 12, the movable groove 12 providing rotation space for the adjustable seat 13 within a fixed angle range, and the adjustable seat 13 being self-locked by rotation with the center of the adjustable seat 13 as the origin through a transmission mechanism, a head positioning frame 2 being installed at the top of the adjustable seat 13, the head positioning frame 2 being welded and fixed to the adjustable seat 13, and the head positioning frame 2 being located on the upper surface of the base 1, the head positioning frame 2 being provided with a head support mechanism 3 for providing different support forces to different areas of the patient's head;

[0024] The surgical head frame of this invention ensures that the surgical site is exposed in the surgical field at the optimal angle, improving the accuracy and success rate of the surgery. Compared with traditional fixed head frames, it allows medical staff to focus more attention on the surgical procedure itself, thus improving surgical efficiency.

[0025] Please see Figure 2The head support mechanism 3 includes multiple elongated airbags 5, which are evenly distributed on the inner surface of the head positioning frame 2. The bottom of the airbags 5 is adhered and fixed to the head positioning frame 2. Multiple air supply branches 6 are installed on the end of each airbag 5 near the end of the operating table 4. Each air supply branch 6 is sequentially and spaced with a pressure sensor 7 and an electric control valve 8. The upper surface of each airbag 5 is covered with non-woven fabric. The head support mechanism 3 also includes an air source box 10, which is fixedly set on the side of the operating table 4 near the front end of the base 1. The air source box 10 contains a microcontroller and an air pump. The air pump outlet is connected to a main air supply pipe 9, and the multiple air supply branches 6 are connected to the main air supply pipe 9. The output end of the pressure sensor 7 is connected to the input end of the microcontroller, and the output end of the microcontroller is connected to the electric control valve 8 and the air pump respectively.

[0026] When it is necessary to position the patient's head, the air pump is turned on, and air enters multiple air supply branches 6 through the main air supply pipe 9. The air pressure sensor 7 monitors the air pressure inside the airbag 5 in real time and feeds the data back to the microcontroller. The electronic control valve 8, according to the instructions of the microcontroller, precisely controls the flow and on / off of the gas in the air supply branches 6. After the air enters the airbag 5 through the air supply branches 6, the airbag 5 begins to inflate. Since multiple airbags 5 are independently distributed in the head positioning frame 2, as the airbags 5 inflate, they can conform to different parts of the patient's head, gradually forming support and positioning for the head. According to the contour of the patient's head and the actual needs, the airbags 5 in different positions adjust their inflation degree according to the coordinated action of the air pressure sensor 7 and the electronic control valve 8, so as to achieve precise support and positioning for multiple positions of the patient's head. Multiple independent airbags 5 can support according to the unique contour of the patient's head. For patients with irregular head shapes, each airbag 5 can independently adjust its inflation degree to achieve uniform pressure distribution and avoid excessive local pressure that may cause patient discomfort. Compared to traditional single-support methods, this method greatly improves patient comfort during surgery, helps patients maintain a stable state during the procedure, reduces involuntary movements caused by discomfort, and lowers surgical risks.

[0027] Please see Figure 3The transmission mechanism includes a transmission rod 14. A through-hole, flush with the bottom surface of the movable groove 12, is provided at one end of the base 1 near the base. The transmission rod 14 is parallel to the upper surface of the through-hole, and one end of the transmission rod 14 passes laterally through and is fixedly connected to the adjusting seat 13. A worm gear 15 is fixedly mounted at the other end of the transmission rod 14. A worm 16 is mounted on one side of the worm gear 15. The lower end of the worm 16 is rotatably connected to the base 1, and the worm 16 and the worm gear 15 are threaded together. A handwheel 11 is mounted at the top of the worm 16. When the handwheel 11 is rotated, the worm 16 drives the worm gear 15 to rotate, thereby adjusting the angle of the head positioning frame 2 supporting the patient's head. The head positioning frame 2 is adjusted to meet the needs of head position adjustment. When the head positioning frame 2 is adjusted to the appropriate position, due to the self-locking characteristics of the worm gear 15 and worm 16, the head positioning frame 2 can remain locked even if it is touched or vibrated by external force during the operation, preventing the patient's head from moving accidentally. This is especially important in long and complex operations, as it can always maintain the stability of the patient's head position, ensure the safety of the operation, and reduce the risk of skin pressure caused by too many fixation devices. In order to improve the aesthetics of the surgical head frame, the transmission mechanism also includes a housing that matches the shape of the through notch. The top of the worm 16 passes through the housing and is fixedly installed with the handwheel 11.

[0028] Please see Figure 1 The base 1 is embedded in a groove on the operating table 4, with its upper surface flush with the upper surface of the operating table 4. This design, which embeds the surgical head frame inside the operating table 4, simplifies the base installation process. During the operating table production stage, this device can be directly integrated and installed, reducing subsequent additional installation steps. In routine maintenance, the close integration of the device with the operating table and its relatively simple structure facilitate overall inspection and repair by medical personnel, reducing maintenance costs and difficulty, improving equipment efficiency and reliability, and ensuring that the operating table and head frame system are always in optimal working condition.

[0029] The surfaces of multiple airbags 5 are covered with non-woven fabric. The non-woven fabric is soft and reduces the direct pressure on the head when it comes into contact with the patient's head, making the patient feel more comfortable and helping the patient maintain a stable state during the operation. At the same time, the non-woven fabric can also serve as a protective layer for the airbags 5, preventing sharp objects such as hair and jewelry from scratching the airbags 5 and extending the service life of the airbags 5.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
