Description

Technical Field

[0001] This invention relates to the field of neurosurgical technology, specifically to a multifunctional head fixation device 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, such as life-threatening cerebral hemorrhage, brain injuries caused by car accidents, or brain tumors that compress the brain and require surgical treatment. When performing head surgery, it is necessary to fix the patient's head to prevent it from moving during the operation, and a head fixation device is used to fix the head.

[0003] A multifunctional head fixation device for pediatric neurosurgery, application number CN202120041306.7, includes a strip-shaped mounting base plate. First electric push rods are mounted upwards at both ends of the base plate. A second electric push rod is mounted at the output end of each first electric push rod. A rotating connector is mounted at the output end of each second electric push rod. Each rotating connector is rotatably connected to a vertically rotating gear. A drive motor is mounted on one side of each rotating connector. The power output shaft of each drive motor is connected to a drive gear meshing with the corresponding rotating gear. A mounting strip extending to both sides is mounted at one end of each rotating gear. Push rod motors are mounted at both ends of each mounting strip. A flexible pad is connected to the output end of each push rod motor. This invention facilitates adjustment of the child's head position according to surgical needs, has a small fixation area, provides a larger surgical field, and is more conducive to surgical observation.

[0004] The device uses an electric push rod to move a flexible pad towards both ends of the head to fix the patient's head. However, the electric push rod is electrically controlled and is unstable. It is easy to apply excessive clamping force during clamping, which may cause secondary injury to the patient's head.

[0005] A multifunctional head fixation device for neurosurgery, with application number CN202120407513.X, belongs to the technical field of head fixation devices. A head fixation component is installed on the fixing and limiting rod assembly, and the head fixation component is equipped with a fixing strap assembly. When the patient lies on the operating table, the drive motor is activated to rotate the rotating rod. The rotation of the rotating rod drives the gear to rotate, which in turn drives the rack to rise and fall and pushes the connecting plate to move. As the connecting plate moves, the limiting rod and fixing rod clamp the patient's head. The patient's head is clamped by the head fixation component and the protective anti-slip pad. After the patient's head is clamped, the first and second fixing straps wrap around the patient's chin, and the device is locked by the limiting buckle and the limiting lock, thereby achieving the effect of head fixation. This device is simpler to operate, can be adjusted and fixed according to the size of the patient's head, and has good stability.

[0006] The device has a structure to fix the patient's head, but the structure is too simple and can only fix the patient's head. When the patient has a tumor in the head that is compressing the nerves, the patient will experience severe pain in the head. If the fixation of the patient's head cannot relieve this pain, it will cause the patient to become emotionally agitated due to headache, thereby affecting the patient's treatment effect.

[0007] Therefore, we propose a multifunctional head fixation device for neurosurgery to address the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a multifunctional head fixation device for neurosurgery, to solve the problems mentioned above. These problems include: the electric push rod, controlled by electricity, is unstable and prone to excessive clamping force, causing secondary injury to the patient's head; the device's structure is too simple, only providing fixation for the patient's head; when a patient has a tumor compressing a nerve in their head, they experience severe head pain; if fixation fails to alleviate this pain, it can cause the patient to become agitated due to headache, thus affecting the treatment outcome.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional head fixator for neurosurgery, comprising a support base, an anti-slip block, a first telescopic rod, a second telescopic rod, a base, and a headrest. An anti-slip block is fixedly installed at the lower end of the support base, and a first telescopic rod is fixedly installed at the upper end of the support base. A second telescopic rod is nested inside the first telescopic rod, and a base is fixedly installed at the upper end of the second telescopic rod. A headrest is fixedly installed at the upper end of the base, and a rubber pad is fixedly installed on the outer side of the headrest. Ventilation holes and through grooves are provided on the inner side of the headrest. A fixing block is fixedly installed at the upper end of the support base, and a sliding rail is fixedly installed inside the fixing block. A first telescopic spring is fixedly installed inside the sliding rail, and a support rod is fixedly connected to the tail end of the first telescopic spring. An airbag clamp is fixedly installed on the outer side of the support rod, and the support rod is nested inside the sliding rail. A traction rope is fixedly connected to the side, and the tail end of the traction rope is fixedly connected to the outside of the base. A sliding rod is fixedly installed on the outside of the first telescopic rod, and a sliding seat is nested on the outside of the sliding rod. A rotating rod is connected to the outside of the sliding seat by a bearing, and the tail end of the rotating rod is connected to the outside of the extrusion block by a bearing. The extrusion block is fixedly installed at the lower end of the base. A limit rod is fixedly installed on the outside of the second telescopic rod, and the limit rod passes through the inside of the sliding seat. A pressure sensor is fixedly installed on the outside of the limit rod. A second telescopic spring is fixedly installed on the outside of the second telescopic rod, and the tail end of the second telescopic spring is fixedly connected to the outside of the sliding seat. A fixing rod is fixedly installed at the lower end of the base, and a notch is opened at the lower end of the fixing rod. A slot is opened on the inside of the fixing rod, and a locking pin is connected to the inside of the slot. A locking pin passes through the inside of the fixing block, and a third telescopic spring is fixedly installed on the inside of the fixing block. The tail end of the third telescopic spring is fixedly connected to the outside of the locking pin.

[0010] Preferably, the support rod and the sliding track form a sliding structure, and the support rod and the sliding track form an elastic structure through the first telescopic spring; the first telescopic spring can use its own elasticity to make the support rod return to its original position.

[0011] Preferably, the airbag clamps are arranged in two sets symmetrically about the midpoint of the headrest, and the airbag clamps are in an inverted "L" shape when viewed from the front; the inverted "L" shape of the airbag clamps can better support the structure of the patient's head and prevent the head from shaking.

[0012] Preferably, the second telescopic rod and the first telescopic rod form a sliding structure, and the upper base of the second telescopic rod forms a traction structure with the support rod through the traction rope; the traction structure formed by the upper base of the second telescopic rod and the support rod through the traction rope can drive the support rod to slide along the inner side of the sliding track.

[0013] Preferably, the sliding seat and the limiting rod form a sliding structure, and the sliding seat and the first telescopic rod form an elastic structure through the second telescopic spring; the second telescopic spring can use its own elasticity to make the sliding seat return to its original position.

[0014] Preferably, the two ends of the rotating rod form a rotating structure with the sliding seat and the pressing block respectively, and the pressing block and the pressure sensor are distributed vertically in correspondence; the vertically corresponding distribution of the pressing block and the pressure sensor can cause the pressure sensor to be activated by the pressing of the pressing block.

[0015] Preferably, the locking pin forms an elastic structure with the fixing block through the third telescopic spring, and the tail end of the locking pin forms an engaging structure with the locking groove; the third telescopic spring can use its own elasticity to make the locking pin reset itself.

[0016] Preferably, a motor is fixedly installed inside the base, and a first bevel gear is fixedly installed at the output end of the motor. A second bevel gear is connected to the outside of the first bevel gear. The second bevel gear is fixedly installed on the outside of a first concentric shaft, and the first concentric shaft is installed inside the base. A third bevel gear is connected to the outside of the second bevel gear, and the third bevel gear is fixedly installed on the outside of a second concentric shaft, and the second concentric shaft is installed inside the base. A massager is fixedly installed on the outside of the second concentric shaft.

[0017] Preferably, there are two sets of the second bevel gears symmetrically distributed about the midpoint of the first concentric axis, and the second bevel gears are meshed with the first bevel gears; the meshing connection between the second bevel gears and the first bevel gears can drive the second bevel gears to rotate and change the direction of rotation by rotating the first bevel gears.

[0018] Preferably, the massager forms a rotating structure with the base via a second concentric shaft, and the third bevel gear on the outer side of the second concentric shaft is meshed with the second bevel gear; the rotating structure formed by the massager with the base via the second concentric shaft allows the outer massage blocks to rub and knead the patient's head, thereby reducing the patient's head pain.

[0019] Compared with the prior art, the beneficial effects of the present invention are: This neurosurgical multifunctional head fixator:

[0020] 1. It is equipped with a stable clamping structure. The weight of the patient's head presses down on the lower headrest. The headrest compresses the second telescopic spring at the lower end and moves downward. As the headrest moves downward, it drives the airbag clamps at both ends to move towards each other through the connection of the traction rope, clamping and limiting the two ends of the patient's head to prevent the patient's head from shaking during the operation.

[0021] 2. A limiting structure is set up. When the base moves downward, the fixing rod at the lower end of the base will squeeze the locking pin through the notch, causing it to move to both ends. When the tail end of the locking pin is flush with the locking groove, the locking pin is reset by the elastic force of the third telescopic spring and engages with the locking pin, thereby fixing the base and preventing the base from moving upward. This would cause the airbag clamps at both ends to lose traction and move to both ends, causing the patient's head to lose its clamping limit.

[0022] 3. It is equipped with a massage structure. When the base moves downward, the squeezing block at the lower end of the base will squeeze the pressure sensor, thereby activating the pressure sensor. The pressure sensor transmits the information to the control module, which controls the motor to run. This drives the massager to rotate through the meshing of the first, second, and third bevel gears. The massage blocks on the outside rub and knead the patient's head, thereby relieving the patient's head pain. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Please see Figure 1-8 This invention provides a technical solution: a multifunctional head fixation device for neurosurgery, comprising a support base 1, an anti-slip block 2, a first telescopic rod 3, a second telescopic rod 4, a base 5, a headrest 6, a rubber pad 7, a ventilation hole 8, a through groove 9, a fixing block 10, a sliding track 11, a first telescopic spring 12, a support rod 13, an airbag clamping block 14, a traction rope 15, a sliding rod 16, a sliding seat 17, a rotating rod 18, a compression block 19, a limiting rod 20, a second telescopic spring 21, a pressure sensor 22, a fixing rod 23, a notch 24, a slot 25, a locking pin 26, a third telescopic spring 27, a motor 28, a first bevel gear 29, a second bevel gear 30, a first concentric shaft 31, a third bevel gear 32, a second concentric shaft 33, and a massager 34.

A first telescopic spring 12 is fixedly installed inside the sliding rail 11, and a support rod 13 is fixedly connected to the tail end of the first telescopic spring 12. An airbag clamp 14 is fixedly installed on the outer side of the support rod 13, and the support rod 13 is nested inside the sliding rail 11. A traction rope 15 is fixedly connected to the outer side of the support rod 13, and the tail end of the traction rope 15 is fixedly connected to the outer side of the base 5. A sliding rod is fixedly installed on the outer side of the first telescopic rod 3. 16, and a sliding seat 17 is nested on the outside of the sliding rod 16. A rotating rod 18 is connected to the outside of the sliding seat 17 by a bearing. The tail end of the rotating rod 18 is connected to the outside of the extrusion block 19 by a bearing. The extrusion block 19 is fixedly installed at the lower end of the base 5. A limit rod 20 is fixedly installed on the outside of the second telescopic rod 4. The limit rod 20 passes through the inside of the sliding seat 17. A pressure sensor 22 is fixedly installed on the outside of the limit rod 20. A second telescopic spring 21 is fixedly installed on the outside of the second telescopic rod 4. The tail end of the second telescopic spring 21 is fixedly connected to the outside of the sliding seat 17. A fixing rod 23 is fixedly installed at the lower end of the base 5. A notch 24 is opened at the lower end of the fixing rod 23. A slot 25 is opened on the inside of the fixing rod 23. A locking pin 26 is connected to the inside of the slot 25. A locking pin 26 passes through the inside of the fixing block 10. A third telescopic spring 27 is fixedly installed on the inside of the fixing block 10. The tail end of the third telescopic spring 27 is fixedly connected to the outside of the locking pin 26.

[0035] according to Figures 1-6 As shown, the support rod 13 and the sliding rail 11 form a sliding structure, and the support rod 13 and the sliding rail 11 form an elastic structure through the first telescopic spring 12; two sets of airbag clamping blocks 14 are symmetrically arranged about the midpoint of the headrest 6, and the airbag clamping blocks 14 are inverted "L" shape when viewed from the front; the second telescopic rod 4 and the first telescopic rod 3 form a sliding structure, and the upper base 5 of the second telescopic rod 4 and the support rod 13 form a traction structure through the traction rope 15; the sliding seat 17 and the limiting rod 20 form a sliding structure, and the sliding seat 17 and the first telescopic rod 3 form an elastic structure through the second telescopic spring 21; the two ends of the rotating rod 18 form a rotating structure with the sliding seat 17 and the squeezing block 19 respectively, and the squeezing block 19 and the pressure sensor 22 are distributed vertically and vertically; the locking pin 26 forms an elastic structure with the fixing block 10 through the third telescopic spring 27, and the tail end of the locking pin 26 forms a locking structure with the locking groove 25;

[0036] When this structure needs to fix the patient's head, the fixator is first placed in a suitable position, and then the patient's head is placed on the upper end of the headrest 6. The headrest 6 is subjected to pressure, which drives the rotating rod 18 at the lower end to rotate, thereby pushing the sliding seat 17 to slide along the outer side of the sliding rod 16 to both ends. As the sliding seat 17 continues to slide, the headrest 6 will continuously move downward. When the headrest 6 moves downward, the traction rope 15 on the outer side of the base 5 will generate traction force on the support rod 13, thereby causing the support rod 13 to slide along the inner side of the sliding track 11, pushing the airbag clamps 14 at both ends to move towards the patient's head, thus clamping and fixing the patient's head. (The airbag clamp 14 has an inverted "L" shape structure), and when the base 5 moves downward, the notch 24 on the outside of the fixing rod 23 at the lower end of the base 5 will continuously squeeze the locking pin 26, thereby causing the locking pin 26 to squeeze the third telescopic spring 27 to move to both ends. When the tail end of the locking pin 26 is flush with the slot 25, the locking pin 26 is reset by the elastic force of the third telescopic spring 27 and engages with the locking pin 26 on the inside of the fixing rod 23, thereby fixing the base 5 at the upper end of the fixing rod 23, preventing the patient's head from moving upward and causing the airbag clamps 14 at both ends to lose traction and move to both ends, thus resulting in insufficient clamping force on the patient's head.

[0037] A motor 28 is fixedly installed inside the base 5, and a first bevel gear 29 is fixedly installed at the output end of the motor 28. A second bevel gear 30 is connected to the outside of the first bevel gear 29. The second bevel gear 30 is fixedly installed on the outside of the first concentric shaft 31, and the first concentric shaft 31 is installed inside the base 5. A third bevel gear 32 is connected to the outside of the second bevel gear 30, and the third bevel gear 32 is fixedly installed on the outside of the second concentric shaft 33, and the second concentric shaft 33 is installed inside the base 5. A massager 34 is fixedly installed on the outside of the second concentric shaft 33.

[0038] according to Figure 1 , Figure 3 , Figures 7-8 As shown, there are two sets of second bevel gears 30 symmetrically distributed about the midpoint of the first concentric shaft 31, and the second bevel gears 30 and the first bevel gears 29 are meshed together; the massager 34 forms a rotating structure with the base 5 through the second concentric shaft 33, and the third bevel gear 32 on the outer side of the second concentric shaft 33 is meshed with the second bevel gear 30.

[0039] As the base 5 moves downward, the pressing block 19 at the lower end of the base 5 will touch the pressure sensor 22, causing the pressure sensor 22 to activate. The pressure sensor 22 transmits a signal to the control module, which controls the motor 28 to run. The motor 28 drives the first bevel gear 29 to rotate. The first bevel gear 29 meshes with the second bevel gear 30, thereby driving the second bevel gear 30 to rotate. The second bevel gear 30 meshes with the third bevel gear 32, thereby driving the third bevel gear 32 to rotate. The third bevel gear 32 drives the massager 34 to rotate via the second concentric shaft 33. When the massager 34 rotates to the position of the through groove 9, it will rub and knead the outside of the head to relieve the patient's head pain.
