Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an innovative head fixation bracket for neurosurgery. Background Technology

[0002] Neurosurgery is a branch of surgery that treats diseases of the brain, spinal cord, and other nervous systems caused by trauma. During neurosurgery on the brain, a fixation device is needed to immobilize the patient's head. This device typically includes a base with a support frame connecting to fixation components. To immobilize the patient's head during surgery, a handwheel inside the fixation component is turned, causing a screw to rotate. This screw, through a threaded connection with the support frame, moves pressure heads. Turning the handwheel brings the two pressure heads closer together, thus compressing and immobilizing the patient's head. However, this method requires manual operation, which is inconvenient. Furthermore, the fixed support frame structure makes adjusting the fixation height based on the patient's head size difficult. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an innovative head fixation bracket for neurosurgery. This device can automatically clamp and fix the patient's head at three points in neurosurgery through transmission and detection elements without manual intervention. At the same time, the device can precisely adjust the vertical position of the fixation points of the patient's head according to actual needs. It is easy to use and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an innovative head fixation bracket for neurosurgery, comprising a mounting frame and a head fixation mechanism;

[0005] Mounting bracket: It has a sliding groove on both the left and right sides at the top;

[0006] The head fixation mechanism includes a horizontal movement frame, a vertical movement frame, a pressure sensor, a mounting base, a right fixation base, a left fixation base, and a vertical adjustment assembly. There are two horizontal movement frames, each slidably connected to a slide groove. A vertical movement frame is slidably connected to a slide groove two opened at the upper end of each horizontal movement frame. Each vertical movement frame has a mounting base connected to a pressure sensor at its upper end. A vertical adjustment assembly is provided between each vertical movement frame and the adjacent horizontal movement frame. Cross-shaped grooves are opened on the opposite inner surfaces of the two mounting bases. The right fixation base is inserted into the right cross-shaped groove, and the left fixation base is inserted into the left cross-shaped groove. This device, through transmission and detection elements, can automatically perform neurosurgical clamping and fixation of the patient's head at three points without manual intervention. Simultaneously, the device can precisely adjust the vertical position of the fixation points on the patient's head according to actual needs, making it convenient to use.

[0007] Furthermore, it also includes a microcontroller, which is located outside the mounting bracket. The input terminal of the microcontroller is electrically connected to an external power supply, and the microcontroller is bidirectionally electrically connected to the pressure sensor, making it convenient to control electrical components.

[0008] Furthermore, the head fixation mechanism also includes studs and motors. The studs are rotatably connected to the inside of the slide grooves via bearings. Each stud is threadedly connected to an adjacent transverse frame. Two motors are provided in the upper inner cavity of the mounting frame. The input ends of the motors are electrically connected to the output ends of the microcontroller. The output shafts of the motors are fixedly connected to adjacent studs, providing power for the device to self-fix the patient's head.

[0009] Furthermore, the vertical adjustment assembly includes a fixed plate, two studs, two motors, and a laser sensor. There are two fixed plates, each disposed inside the slide groove. The upper side of each fixed plate is rotatably connected to a stud via a bearing. Each stud is threadedly connected to an adjacent vertical adjustment frame. The lower side of each fixed plate is equipped with a motor. The input end of each motor is electrically connected to the output end of a microcontroller. The output shaft of each motor is fixedly connected to an adjacent stud. The upper side of each fixed plate is equipped with a laser sensor, which is bidirectionally electrically connected to the microcontroller. This allows for precise vertical position adjustment of the patient's head fixation point according to actual needs.

[0010] Furthermore, each of the mounting bases has a locking pin slidably connected in its sliding hole. Each locking pin has a knob at its upper end, and a spring is provided between the knob and the adjacent mounting base. The spring is movably sleeved with the outer side of the adjacent locking pin. Locking holes are provided at the opposite ends of the right and left fixing bases, and the locking pins are inserted into the adjacent locking holes, which facilitates the replacement of the fixing components in the innovative head fixation bracket used for neurosurgery.

[0011] Furthermore, both the right and left fixation seats are coated with silicone to prevent the patient's head from being scratched due to excessive pressure on the fixation area. At the same time, by increasing contact friction, relative sliding between the fixation area and the patient's head is prevented.

[0012] Furthermore, the mounting frame is a carbon fiber frame, which reduces the overall weight of the device while increasing its compressive strength.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: an innovative head fixation bracket for neurosurgery, including a mounting frame 1 and a head fixation mechanism 3;

[0023] Mounting frame 1: It has a sliding groove on both the left and right sides of its upper end. The outer sides of the right fixing seat 35 and the left fixing seat 36 are coated with silicone. Mounting frame 1 is a carbon fiber frame. The silicone coating makes the outer surface of the right fixing seat 35 and the left fixing seat 36 flexible, so as to avoid the right fixing seat 35 and the left fixing seat 36 from being rigidly squeezed when fixing the patient's head. This avoids the patient's head being scratched due to excessive pressure on the fixing part. The silicone coating also increases the contact friction resistance between the right fixing seat 35 and the left fixing seat 36 and the patient's head, preventing relative sliding between them. Mounting frame 1 uses a carbon fiber frame, which reduces the overall weight of the device while increasing the compressive strength of the device.

[0024] The head fixing mechanism 3 includes a horizontal moving frame 31, a vertical moving frame 32, a pressure sensor 33, a mounting base 34, a right fixing base 35, a left fixing base 36, and a vertical adjustment component 39. There are two horizontal moving frames 31, each slidably connected to a slide groove 1. A vertical moving frame 32 is slidably connected to a slide groove 2 at the upper end of each horizontal moving frame 31. A mounting base 34 is provided at the upper end of each vertical moving frame 32 via a pressure sensor 33. A vertical adjustment component 39 is provided between each vertical moving frame 32 and the adjacent horizontal moving frame 31. Cross grooves are provided on the opposite inner surfaces of the two mounting bases 34. A right fixing base 35 is inserted into the right cross groove, and a left fixing base 36 is inserted into the left cross groove. The mechanism also includes a microcontroller 2, located outside the mounting frame 1. The input terminal is electrically connected to an external power supply. The microcontroller 2 is bidirectionally electrically connected to the pressure sensor 33. The head fixing mechanism 3 also includes stud 37 and motor 38. The stud 37 is rotatably connected to the inside of the slide groove 1 through bearing 1. The stud 37 is threadedly connected to the adjacent transverse frame 31. Two motors 38 are provided in the upper inner cavity of the mounting frame 1. The input terminals of the motors 38 are electrically connected to the output terminals of the microcontroller 2. The output shafts of the motors 38 are fixedly connected to the adjacent stud 37. The vertical fine adjustment assembly 39 includes a fixing plate 391, a stud 392, a motor 393, and a laser sensor 394. There are two fixing plates 391, which are respectively set inside the slide groove 2. The upper side of the fixing plates 391 is rotatably connected to the slide groove 2 through bearing 2. Each mounting plate 391 is equipped with studs 392, which are threadedly connected to adjacent vertical moving brackets 32. Motors 393 are mounted on the lower side of each mounting plate 391, with their input terminals electrically connected to the output terminals of microcontrollers 2. The output shafts of motors 393 are fixedly connected to adjacent studs 392. Laser sensors 394 are mounted on the upper side of each mounting plate 391, and are bidirectionally electrically connected to microcontrollers 2. Locking pins 4 are slidably connected within the sliding holes of mounting bases 34. A knob 5 is mounted on the upper end of each locking pin 4, and a spring 6 is positioned between the knob 5 and the adjacent mounting base 34. The spring 6 is movably sleeved on the outer side of the adjacent locking pin 4. Locking holes are opened at the opposing ends of the right mounting base 35 and the left mounting base 36. Locking pins 4 are connected to adjacent... The device is inserted through a locking hole. During neurosurgical procedures to fix the patient's head, the device is first fixed to the operating table using mounting bracket 1. Then, medical staff place the patient's head on the device's fixing point. Microcontroller 2 then activates motor 38, causing its output shaft to rotate the corresponding stud 37. The stud 37, through a threaded connection, allows the transverse sliding bracket 31 to slide inwards along a groove. The transverse sliding bracket 31 indirectly drives the corresponding right fixing seat 35 and left fixing seat 36 to move closer together, thus clamping and fixing the patient's head through three-point support. Simultaneously, microcontroller 2 activates pressure sensor 33. Pressure sensor 33 detects the horizontal pressure on mounting seat 34 through a detection element and transmits the detection result to microcontroller 2 as an electrical signal.When the right fixation seat 35 and the left fixation seat 36 come into contact with the patient's head, the microcontroller 2 obtains the pressure detection value transmitted by the pressure sensor 33. When the pressure detection value reaches a certain level, the microcontroller 2 shuts off the motor 38 in a timely manner according to the pressure value, thereby automatically and quickly clamping and fixing the patient's head. This is suitable for head fixation operations for patients of different ages during neurosurgical procedures. At the same time, during the neurosurgical procedure, the microcontroller 2 can start the motor 393 according to actual needs, causing its output shaft to drive the stud 392 to rotate. The stud 392, through a threaded connection, causes the vertical moving frame 32 to slide vertically along the slide groove, thereby adjusting the vertical position of the patient's head fixation part of the device. During this process, the microcontroller 2 activates the laser sensor 394, which emits a light signal that shines on the lower side of the vertical moving frame 32 and reflects back to the initial position. The vertical moving distance of the vertical moving frame 32 along the slide groove is obtained based on the propagation time and speed of the light signal. The laser sensor 394 transmits the detection results. The electrical signal is transmitted to the microcontroller 2. The microcontroller 2 controls the start and stop of the motor 393 based on the vertical movement distance of the vertical moving frame 32 measured by the laser sensor 394. This allows the device to precisely adjust the vertical position of the fixation point on the patient's head as needed. It is easy to use. When replacing the right fixation seat 35 or the left fixation seat 36, simply move the lever 5 upward to move the locking pin 4 upward, so that the locking pin 4 is away from the adjacent locking hole, thereby releasing the installation limit on the right fixation seat 35 or the left fixation seat 36. Then, the right fixation seat 35 or the left fixation seat 36 can be pulled out along the corresponding cross groove for replacement. The operation is convenient. The spring 6 is always in an elastic contraction state. The contraction force of the spring 6 prevents the relative sliding separation of the locking pin 4 and the locking hole after insertion. Through the transmission element and the detection element, the device can automatically clamp and fix the three points of the patient's head for neurosurgical purposes without manual operation. At the same time, the device can precisely adjust the vertical position of the fixation point on the patient's head as needed. It is easy to use.

[0025] The working principle of the innovative head fixation bracket for neurosurgery provided by this utility model is as follows: When fixing the patient's head during neurosurgery, the device is first fixed to the operating table by the mounting bracket 1. Then, the medical staff places the patient's head on the fixing part of the device. Subsequently, the microcontroller 2 starts the motor 38, causing its output shaft to drive the corresponding stud 37 to rotate. The stud 37 is connected by threads, which causes the transverse frame 31 to slide inward along the slide groove. The transverse frame 31 indirectly drives the corresponding right fixation seat 35 and left fixation seat 36 to move closer to each other. Through three-point support, the patient's head is clamped and fixed. At the same time, the microcontroller 2 starts the pressure sensor 33. The pressure sensor 33 detects the horizontal pressure on the mounting seat 34 through the detection element. The system performs detection and transmits the results to the microcontroller 2 via electrical signals. When the right fixation seat 35 and the left fixation seat 36 come into contact with the patient's head, the microcontroller 2 obtains the pressure detection value transmitted by the pressure sensor 33. When the pressure detection value reaches a certain level, the microcontroller 2 shuts off the motor 38 in a timely manner based on the pressure value, thereby automatically and quickly clamping and fixing the patient's head with high precision. This is suitable for head fixation operations for patients of different ages during neurosurgical procedures. Simultaneously, during neurosurgical procedures, the microcontroller 2 can start the motor 393 according to actual needs, causing its output shaft to drive the stud 392 to rotate. The stud 392, through a threaded connection, allows the vertical moving frame 32 to slide vertically along the slide groove, thereby adjusting the device's position. During the vertical adjustment of the patient's head fixation point, the microcontroller 2 activates the laser sensor 394. The laser sensor 394 emits a light signal that illuminates the lower side of the vertical moving frame 32 and reflects back to the initial position. Based on the propagation time and speed of the light signal, the vertical moving distance of the vertical moving frame 32 along the second slide groove is obtained. The laser sensor 394 transmits the detection result to the microcontroller 2 as an electrical signal. The microcontroller 2 controls the start and stop of the second motor 393 based on the vertical moving distance of the vertical moving frame 32 measured by the laser sensor 394. This allows the device to accurately adjust the vertical position of the patient's head fixation point as needed. It is easy to use. The silicone coating gives the outer surfaces of the right fixation seat 35 and the left fixation seat 36 a certain degree of flexibility, preventing the right fixation seat 35 and the left fixation seat 36 from clashing. When fixing the patient's head, the 36-piece fixing device applies rigid compression to prevent scratches caused by excessive pressure. A silicone coating increases the frictional resistance between the right and left fixing brackets 35 and the patient's head, preventing relative sliding. The mounting frame 1 uses a carbon fiber frame, reducing the overall weight of the device while increasing its compressive strength. To replace either the right or left fixing bracket 35, simply move the lever 5 upwards to move the locking pin 4 away from the adjacent locking hole, releasing the installation restriction on either the right or left fixing bracket 35. Then, the right or left fixing bracket 35 can be easily pulled out along the corresponding cross groove for replacement. The operation is convenient.Spring 6 is always in an elastically contracted state. The elastic force of spring 6 prevents relative sliding and separation between the locking pin 4 and the locking hole after they are inserted.

[0026] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a COP8CBE9, the pressure sensor 33 can be an MPM270 high-stability and high-precision pressure sensor, both motor 1 38 and motor 2 393 can be WS-50ZYT78-R, and the laser sensor 394 can be a WH-LRF laser rangefinder. The microcontroller 2 controls the operation of the pressure sensor 33, motor 1 38, motor 2 393 and laser sensor 394 using methods commonly used in the prior art.
