Description
Technical Field
The invention relates to the field of medical equipment, in particular to an ultrasonic probe frame with good fixation in transcranial Doppler operation.
Background
Transcranial Doppler (TRANSCRANIAL DOPPLER, TCD) is a noninvasive method for examining cerebral vascular diseases by using ultrasonic Doppler effect to detect the blood flow dynamics and blood flow physiological parameters of main intracranial arteries, which uses pulse Doppler technique and 2MHz transmitting frequency to make ultrasonic sound beam penetrate the thinner part of skull and directly trace Doppler signal of blood flow of intracranial arteries to obtain the blood flow dynamics parameters of intracranial arteries to reflect cerebral vascular function state. If in carotid endarterectomy of patients with severe carotid stenosis, the middle cerebral artery of the patients is monitored by using dual-channel dual-depth TCD in the whole process, and the operation mode is determined by analysis of obtained Doppler data (whether current is needed after blocking the common carotid artery or not is judged), anesthesia is guided to adjust the dosage, whether the conditions of micro-embolization fall off in the operation process and whether excessive perfusion exists after blocking the arterial opening or not is judged, and the stability of a headstock plays a vital role in the operation process.
When the transcranial Doppler ultrasonic instrument is used for examination, the ultrasonic probe frame is worn on the head of a patient, the patient is in a lying position, the ultrasonic probe is fixed on the ultrasonic probe frame and acts on the temporal window of the patient, the thinner part and the natural pore canal of the skull can be penetrated, doppler echo signals of main arteries of the skull base are obtained, then the electric signals are transmitted to the display screen, and a doctor observes through the display screen.
The defects in the prior art are as follows: during the operation, part of doctors can deflect the head of a patient to one side, so that the operation area is conveniently exposed; however, because the patient is in a lying position, a part of the ultrasonic probe frame is positioned in the head rest area of the patient, so when the head of the patient is deviated to one side or the operation amplitude of an operator is slightly larger, the ultrasonic probe is easy to drive to move, so that the position of the ultrasonic probe acting on the head of the patient is changed, the position of the ultrasonic probe needs to be readjusted, if the operation is started, a disinfecting operation towel is completed, an ultrasonic doctor carries out probe adjustment again, the risk of polluting the operation area exists, if the operation is carried out in an important operation stage, the middle cerebral artery cannot be explored due to the position deviation of the probe, cerebral vascular low flow, excessive perfusion and the like are difficult to monitor, the operation is hindered, and life health of the patient cannot be better protected.

As shown in fig. 2, the two fixing frames are respectively mounted on the left ear muff firmware 20 and the right ear muff firmware 30. The mount includes: mounting plate 501, base plate 502, slide bar 503 and fixing member.
The mounting plates 501 are arranged along the front-back direction, and the rear ends of the two mounting plates 501 are respectively fixed at the front ends of the left earmuff firmware 20 and the right earmuff firmware 30; the sliding rods 503 are arranged along the left-right direction, and the end parts of the two sliding rods 503 are respectively fixed on the opposite sides of the two mounting plates 501; the number of the base plates 502 is two, and an ultrasonic probe 5022 is fixed at the upper end of the base plates 502; the substrate 502 is provided with a through groove 5021 which penetrates left and right along the length direction; the width of the through groove 5021 is 1.1 times of the diameter of the slide bar 503, so that the base plate 502 can be sleeved on the slide bar 503 in a sliding manner along the left-right direction, the base plate 502 can rotate around the slide bar 503, and the through groove 5021 can slide on the outer wall of the slide bar 503 along the length direction; the two fixing members are respectively fixed on the two slide bars 503 and are used for fixing the base plate 502 on the slide bars 503.
When the ultrasonic probe 5022 is fixed by using the fixing frame, firstly, the through groove 5021 slides on the outer wall of the slide rod 503 along the length direction of the through groove 5021 and the base plate 502 rotates around the slide rod 503 until the ultrasonic probe 5022 is opposite to the temporal window of the head of a patient; secondly, the base plate 502 is slid along the left-right direction until the ultrasonic probe 5022 abuts against the temporal window of the head of the patient; finally, the substrate 502 may be fixed by a fixing member.
As shown in fig. 2, the fixing member includes: an outer wing nut 5041 and an inner wing nut 5042; an outer wing nut 5041 and an inner wing nut 5042 are respectively screwed on the slide bar 503.
When the base plate 502 is fixed on the slide bar 503, the outer butterfly nut 5041 and the inner butterfly nut 5042 are screwed, so that the base plate 502 is clamped between the side of the outer butterfly nut 5041 facing the mounting plate 501 and the side of the inner butterfly nut 5042 facing away from the mounting plate 501; by the above setting, the left and right positions of the base plate 502 are adjustable, so that the fixed ultrasonic probe 5022 just abuts against the temporal window of the head of the patient.
As shown in fig. 2, the fixation member further includes a spring 5043. The spring 5043 is sleeved on the sliding rod 503. When the base plate 502 is fixed to the slide bar 503, the spring 5043 is between the side of the outer wing nut 5041 facing the mounting plate 501 and the side of the base plate 502 facing away from the mounting plate 501.
When the base plate 502 is secured, the outer wing nut 5041 is screwed towards the mounting plate 501, causing the spring 5043 to compress, causing the spring 5043 to apply a force to the base plate 502 towards the mounting plate 501, thereby enabling the ultrasound probe 5022 on the base plate 502 to be held tightly against the temporal window of the patient's head. Meanwhile, the spring 5043 can also provide screwing buffer force, so that the ultrasonic probe 5022 on the base plate 502 can not directly abut against the temporal window of the head of the patient to cause pain to the patient after propping against the temporal window of the head of the patient.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but rather is intended to cover any equivalents of the structures or equivalent processes disclosed herein or in the alternative, which may be employed directly or indirectly in other related arts.
