Description

Technical Field

[0001] The present invention relates to the field of medical devices, and specifically to a transcranial Doppler intraoperative ultrasound probe holder with good fixation. Background Art

[0002] Transcranial Doppler (TCD) is a non-invasive cerebrovascular disease examination method that uses the ultrasonic Doppler effect to detect the hemodynamics and blood flow physiological parameters of the main intracranial arteries. It uses pulsed Doppler technology and a 2MHz emission frequency to enable the ultrasonic beam to penetrate through the thinner parts of the skull and directly record the Doppler signals of the intracranial artery blood flow, so as to obtain the hemodynamic parameters of the intracranial arteries and reflect the cerebrovascular function status. For example, during carotid endarterectomy in patients with severe carotid stenosis, a dual-channel and dual-depth TCD is used to monitor the middle cerebral artery of the surgical patient throughout the operation, and the operation method is determined through the analysis of the obtained Doppler data (judging whether bypass is needed after blocking the common carotid artery), guiding the adjustment of the anesthesia drug dosage, judging the situation of microembolus detachment during the operation, and whether there is hyperperfusion after the blocked artery is opened. The stability of the head frame plays a crucial role during the operation.

[0003] When using a transcranial Doppler ultrasound instrument for examination, the ultrasound probe holder is worn on the patient's head. The patient lies flat, and the ultrasound probe is fixed on the ultrasound probe holder and acts on the patient's temporal window, which can penetrate through the thinner parts of the skull and natural channels to obtain the Doppler echo signals of the main arteries at the base of the skull, and then the electrical signals are transmitted to the display screen for the doctor to observe through the display screen.

[0004] The defects existing in the above-mentioned prior art are that due to the different body shapes and head sizes of people, it is inconvenient for the transcranial Doppler ultrasound instrument to fix the heads of different people, and it is also inconvenient to adjust the angle for different people, resulting in inconvenience in exposing the surgical area.

[0005] The present invention aims to solve the technical problems existing in the prior art, and for this purpose, a transcranial Doppler intraoperative ultrasound probe holder with good fixation is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a transcranial Doppler intraoperative ultrasound probe holder with good fixation to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A transcranial Doppler intraoperative ultrasound probe holder with good fixation, including a hospital bed, on one side of which an installation device is provided. The installation device is rotatably connected to the ultrasound instrument main body, and the installation device cooperates with the ultrasound instrument main body;

[0009] The main body of the ultrasonic instrument is slidably connected with an inspection component. A fixing device is arranged inside the main body of the ultrasonic instrument. The fixing device is matched with the inspection component. One side of the main body of the ultrasonic instrument is rotatably connected with an adjusting device. The adjusting device is threadedly connected with the fixing device.

[0010] As a further scheme of the present invention: The installation device includes a support block. The support block is fixedly connected with the hospital bed. One end of the support block is rotatably connected with a rotating plate. One end of the support block is fixedly connected with a vertical plate. Both the rotating plate and the vertical plate are provided with ball bearings. The ball bearings are matched with the main body of the ultrasonic instrument. A limit pin is arranged on one side of the rotating plate. The limit pin is used for limiting the main body of the ultrasonic instrument. A fixing bolt is arranged on one side of the rotating plate. The fixing bolt penetrates through the rotating plate and the vertical plate. The fixing bolt is threadedly connected with the rotating plate and the vertical plate. The fixing bolt is used for limiting the rotating plate.

[0011] As a further scheme of the present invention: The main body of the ultrasonic instrument includes a mounting base. Sliding grooves are formed on both sides of the mounting base. The ball bearings are located in the sliding grooves and are in sliding contact with the mounting base. The ball bearings support the mounting base through the sliding grooves. A soft pillow is arranged on one side of the mounting base. The mounting base is slidably connected with the inspection component.

[0012] As a further scheme of the present invention: The inspection component includes a moving rod. The moving rod is vertically and slidably connected with the mounting base. One end of the moving rod is fixedly connected with a welding block. The other end of the welding block is fixedly connected with a mounting bracket. A detector is arranged on one side of the mounting bracket.

[0013] As a further scheme of the present invention: One end of the moving rod is fixedly connected with a spring. The other end of the spring is fixedly connected with the mounting base. A card slot is formed on one side of the moving rod. The moving rod is fixedly connected with a number of triangular teeth. The triangular teeth are located in the card slot. The triangular teeth are matched with the fixing device.

[0014] As a further scheme of the present invention: The fixing device includes a moving block. The moving block is located in the mounting base and is slidably connected with the mounting base. A plug rod is slidably connected to the moving block. A connecting piece is fixedly connected to one side of the moving block. The connecting piece is threadedly connected with the adjusting device. A elastic piece is arranged on one side of the connecting piece. The elastic piece is in contact with the plug rod.

[0015] As a further scheme of the present invention: The adjusting device includes a turning handle. The turning handle is rotatably connected with the mounting base. One end of the turning handle is fixedly connected with a bolt. The bolt penetrates through the connecting piece and is threadedly connected with the connecting piece.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: When the device is in use, since the mounting base is connected to the ball through the sliding groove, that is, the mounting base can rotate. The mounting base drives the welding block to rotate through the moving rod, and the welding block drives the mounting frame and the detector to rotate, so that the detection position of the detector can be adjusted. Then, the mounting base is limited by the limit pin, and the detector can be fixed, which is convenient for exposing the surgical area. At the same time, the rotating plate is limited by the fixing bolt, that is, by rotating the fixing bolt, the rotating plate can be connected to the vertical plate, and the limit on the rotating plate can be cancelled, that is, the rotating plate can rotate. When the rotating plate rotates, the ball leaves the sliding groove, that is, the support of the ball on the mounting base is cancelled, which is convenient for disassembling and maintaining the mounting base and the detector. By rotating the turning handle, the turning handle drives the bolt to rotate. Since the bolt is threadedly connected to the connecting piece, the connecting piece moves when the bolt rotates. The connecting piece drives the moving block and the elastic piece to move, and the elastic piece and the moving block drive the insertion rod to move and insert into the triangular teeth to limit the moving rod. Conversely, the limit on the moving rod is cancelled, that is, the moving rod can move vertically. The moving rod drives the mounting frame to move through the welding block to fix the skull. The device can conveniently fix the skulls of different people and at the same time conveniently adjust the angle for different people, which is convenient for exposing the surgical area.
