Khamphani ea rona e na le litokelo tsohle tse ikemetseng tsa thepa bakeng sa sehlahisoa sena, 'me e fumane setifikeiti se' maloa sa patent. Sehlahisoa se fihlile maemong a holimo a etellang pele le a machabeng ka ho nepahala ha litekanyo, phoso ea litekanyo le boleng ba setšoantšo sa B-scan sa A-ultrasound, haholo-holo ts'ebeliso ea bongaka, e bohlale le e nang le botho. Lihlahisoa li sebelisoa lipetlele naheng ka bophara, 'me li hapile thoriso e lumellanang.


Tlhaloso ea Sehlahisoa

Thepa e na le litšobotsi tse latelang:

Ea bobeli, boleng ba A-ultrasonic measurement bo nepahetse, 'me ho nepahala ha litekanyo ke 0.02mm; e sebelisoa lipetleleng tse kang Western Theatre Hospital e Chengdu, Sichuan Armed Police Corps Hospital, le Yibin First People's Hospital, basebeletsi ba ts'ebeletso ea kamora ho rekisa ba ile ba amohela matichere a sebelisoang ke lipetlele tsena ha ba khutla. Ho latela maikutlo a fanoeng, liphetho tsa litekanyo tsa AB ultrasound le A ultrasound li ile tsa bapisoa le sephetho sa 'nete sa litekanyo tsa IOL master le lenstar900 ka nako e le' ngoe, 'me phoso e ne e le kahare ho 0.02mm. Ha u kopana le bakuli ba ikhethang, joalo ka bakuli ba nang le lera le teteaneng, ho nepahala ho hoholo ha mochini oa k'hamphani ea rona A le hona ho phahame haholo ho feta mechini e meng e ts'oanang. Mochini oa k'hamphani ea rona o sebelisa mahlale a tsoetseng pele a ts'ebetso le li-algorithms ho sebetsaneng le ho khetholleng li-echoes tsa A-ultrasound. Boikutlo ba echo bo phahame, bophara bo moqotetsane, 'me ka bohlale bo ka khetholla kamore e ka pele, lense le retina.

Haeba phaposi e ka pele le lense echo li ke ke tsa tsebahatsoa ka nepo ha li metha katse ea mahlo, ka mohlala, haeba kamore e ka pele e lekantsoe ka lense e ka tlase ho 2mm le lense tse ling tse 2mm, o tla utloa eka bolelele ba axial ha bo so fetohe, ha e le hantle (2 /1532*1661-2=0.17), Ka lebaka la phapang ea lebelo la molumo, tšusumetso ea hoqetela bolelele ba selepe sa mahlo e ka fihla ho 0.1-0.2mm.

Second, the intelligent recommendation function of IOL calculation formula: the instrument automatically recommends SRKT (selected when the long eye axis, eye axis length ﹥25mm), HOFFER-Q (short eye axis, when the eye axis length ≤ 20mm according to the measurement result of the eye axis length Choose), HOLLADAY (normal eye axis, 20mm <when ​​the eye axis length is less than 25mm), the appropriate one of the three formulas and SRK-Ⅱ will calculate the degree of intraocular lens at the same time for doctors to choose. Doctors can also choose one of the five formulas of SRKT, BINKHORST, HOFFER-Q, HOLLADAY, HAIGIS, and SRK-Ⅱ formula to calculate the intraocular lens power at the same time according to their own experience. This feature is our company's first recommendation.

Third, when the measurement error of A-scan is too large, the array will automatically retest. When encountering a more special patient, such as: vitreous turbidity and severe bleeding, the turbidity point and the bleeding point are on the visual axis, and the echo amplitude and position meet the automatic freezing conditions. At this time, the A-scan will use this point as The retinal echo causes a large deviation in the array. If the testing doctor is negligent or is unfamiliar with the use of the instrument and does not manually delete the set of data, the patient may experience excessive deviation in the degree after surgery. In order to avoid this situation, after 9 sets of data measured by our company's A-ultrasound, it is immediately compared with the average value. When there is a large error in one or several sets of measurement data, the system will automatically mark the array with large error and alarm. Measure the marked data. This function is currently only available in our company.

Fourth, the B-ultrasound image is clear, fully digitalized, and the signal is rich and delicate.

Fifth, B-ultrasonic frequency conversion launch, real-time comparison. The transmitting frequency of the B-ultrasound probe can be adjusted in real time from 8MHz to 11MHz. This technology has obtained a national invention patent.

Sixth, B-ultrasound probe drive adopts all-digital subdivision drive circuit, 256 steps, one-step transmission, the drive is more stable, the position accuracy is higher, and the sound and vibration are smaller. This technology has applied for a national invention patent.

Seventh, the detection depth can be adjusted in real time during B-scanning, and the image can be zoomed in and out in real time, so that the doctor can better observe the small lesions.

Eighth, 256 movies are played back frame by frame, and the playback images can be frozen at any time, and screenshots can be selected frame by frame. It is convenient to select and save the typical case map.

Ninth, with the computer and SDK180 operating software, it can realize the operation of saving, recalling and printing cases.
