Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a magnetic resonance imaging navigation device used for a neurosurgery suction device. Background Art

[0002] In neurosurgery, the aspirator is a simple but extremely important basic surgical instrument. It can play multiple roles during the operation. It can remove blood and water during the operation and clear the surgical field of view. The aspirator can also be used as a blunt separator. When using the aspirator to perform brain surgery on the patient, medical staff need to detect the patient's lesions through magnetic resonance imaging before the operation. It is not convenient to perform magnetic resonance imaging of the lesions in real time.

[0003] After searching, for example, the patent number CN109805992A discloses a puncture surgery positioning device under nuclear magnetic resonance, including a seat, a cylinder connection seat, a sliding buckle and a telescopic slot are provided on the seat, and an upper cover plate and a lower cover plate are provided at the top and bottom of the seat respectively, an upper telescopic connector and a first hydraulic pusher are provided on the upper cover plate, a lower telescopic connector is provided on the lower cover plate, an electronic telescopic column is embedded in the telescopic slot, and the push column of the first hydraulic pusher is fixedly connected to the electronic telescopic column, and an extension column is provided on the electronic telescopic column, and a limit ring sleeve and a sleeve box are provided on the extension column, and the sleeve box and the limit ring sleeve are welded integrated structures. The transmission of the independent equipment effectively avoids the problems of damage to the transmission parts or loose connection of the parts, which causes the difficulty of detection and long maintenance time. When the independent equipment fails, the equipment can be repaired or replaced in a targeted manner, which effectively shortens the equipment maintenance time.

[0004] Another example is the patent number CN110215283A, which discloses an intracranial surgical navigation system based on magnetic resonance imaging, including a preoperative planning module, a positioning conversion module, a three-dimensional neuroimaging visualization module, a three-dimensional neuroimaging rapid segmentation module, and an intraoperative guidance module. The surgical navigation system of the present invention can apply computer-aided technology and magnetic resonance imaging technology to intracranial surgery, effectively helping doctors to perform preoperative surgical planning, intraoperative surgical positioning and guidance, and assisting surgical operations, thereby reducing the difficulty of surgery and improving treatment accuracy and effect.

[0005] Based on the above, the traditional magnetic resonance imaging navigation device used in neurosurgery suction devices is generally a desktop structure. There is no structure that can perform magnetic resonance imaging of the patient's brain in time. The patient needs to undergo MRI before the operation. There is generally no structure that can adjust the horizontal angle of the patient's neck and head. The vertical angle of the patient's neck cannot be adjusted. The neck cannot be supported while keeping the front end of the neck plate at a horizontal height, so that the patient's head can always be aligned with the hole in the working part of the small MRI machine on the front side. It is not convenient for further MRI imaging of the head, and the surgeon cannot navigate the position of the suction device by observing the patient's brain information on the transmission screen.

[0006] Therefore, the existing demand is not met, and we propose a magnetic resonance imaging navigation device for a neurosurgery aspirator. Summary of the invention

[0007] 1. Technical issues

[0008] The purpose of the present invention is to provide a magnetic resonance imaging navigation device for use in a neurosurgery suction device, so as to solve the problem proposed in the above-mentioned background technology that the traditional magnetic resonance imaging navigation device for use in a neurosurgery suction device is generally a desktop structure, and is not provided with a structure that can perform magnetic resonance imaging of the patient's brain in time. The patient needs to undergo nuclear magnetic resonance (MRI) before surgery. Generally, there is no structure that can adjust the horizontal angle of the patient's neck and head, and the vertical angle of the patient's neck cannot be adjusted. The neck cannot be supported while keeping the front end of the neck plate at a horizontal height, so that the patient's head can always be aligned with the hole in the working part of the small magnetic resonance machine on the front side, which is not convenient for further nuclear magnetic resonance imaging of the head, and the surgeon cannot navigate the position of the suction device by observing the patient's brain information on the transmission screen.

[0014] (III) Beneficial effects

[0015] 1. The present invention sets a top reciprocating screw and controls the operation of the top reciprocating screw. The top fixing frame can be driven to move horizontally by the ball nut seat moving horizontally on the inner side of the top reciprocating screw, thereby driving the small magnetic resonance imaging machine at the bottom of the top fixing frame to move horizontally. The small magnetic resonance imaging machine is moved toward the patient's head above the upper limb board, so that the cranial radio frequency coil on the inner side of the small magnetic resonance imaging machine can be sleeved on the outer side of the patient's head.

[0016] 2. The present invention also provides an upper limb board. After the patient lies on the top surface of the upper limb board, the medical staff manually turns the adjusting hand wheel to rotate the worm coaxial with the adjusting hand wheel, thereby causing the internal threaded worm wheel meshing with the worm to rotate, so that the threaded rod inside the internal threaded worm wheel can perform vertical movement through thread transmission, thereby driving the base platform hinged at the bottom of the threaded rod to move vertically, thereby driving the hinged rod hinged at the top of the base platform to slide vertically in the two groups of circular through holes on the front side of the fixed middle plate, so that the hinged rod can drive the upper limb board hinged at its top to flip, and the flipping angle of the upper limb board can be adjusted.

[0017] 3. The present invention also provides an arc-shaped receiving seat, so that after the patient lies on the top surface of the upper limb board, the patient's neck rests on the top surface of the three groups of arc-shaped receiving seats, and the left and right distance of the arc-shaped receiving seat inside the neck reciprocating screw can be adjusted by rotating the three groups of small hand wheels, so that the horizontal angle of the patient's neck and head can be adjusted, so that the patient's head can be aligned with the inner curved side of the small magnetic resonance machine, so as to facilitate nuclear magnetic resonance imaging of the head;

[0018] 4. In the present invention, each arc-shaped receiving seat is provided with a protective airbag on the outer ring, and a pressure sensor is provided in the protective airbag. When adjusting the left and right distance of each arc-shaped receiving seat to adjust the left and right distance, pressure is applied to different parts of the patient through the mutual displacement of the protective airbags, which is convenient for fixing the required detection part of the head, thereby realizing accurate detection; at the same time, the pressure change detected by the pressure sensor can sense the shaking of the patient's head during nuclear magnetic resonance imaging, so that the pressure signal detected in real time by the pressure sensor is fed back to the information processing unit of the small magnetic resonance machine. When the pressure data remains stable, the information processing unit controls the small magnetic resonance machine to perform magnetic resonance imaging, and when the pressure data suddenly changes, the small magnetic resonance machine stops magnetic resonance imaging and sends a reminder to the patient to avoid shaking of the head.
