Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a device for detecting cerebral vascular thrombosis. Background Art

[0002] Transcranial Doppler, abbreviated as TCD, uses the Doppler effect of low-frequency pulsed ultrasound to detect intracranial and extracranial blood vessels. It uses the naturally weak parts of the human skull as detection windows, such as the temporal bone ridges, foramen magnum, eye sockets, etc. It is a non-invasive vascular disease examination method for the hemodynamics of the skull base artery and various blood flow physiological parameters. It has developed rapidly at home and abroad in recent years and has become one of the important means of diagnosing cerebrovascular diseases.

[0003] When using the existing TCD technology, medical staff generally need to stick the probe to the weak position of the skull on the patient's head, and the test results are displayed on a display screen. Therefore, the medical staff needs to use their hands to pull the probe to move at different weak positions of the skull while looking at the image on the display screen. Therefore, the medical staff's hand stability is required to be high. In addition, when the probe is brought close to and attached to the patient's head, the patient may unconsciously deviate away from the probe, which may easily affect the test results.

[0004] Based on the above problems, some prior arts were found after searching, which are introduced one by one: The Chinese invention patent application with application publication number CN115005865A discloses an adjustable probe mounting helmet for TCD foaming test, which can be worn on the patient's head, and uses a surrounding restraint belt and a top restraint belt to form a good restraint fixation to achieve stable wearing of the helmet assembly on the head. The mounting mechanism for mounting the TCD probe is arranged on the surrounding restraint belt of the helmet assembly, and the mounting mechanism can drive the TCD probe to move parallel to the patient's head detection area, so as to achieve the purpose of automatically adjusting the position of the TCD probe. The Chinese utility model patent with authorization announcement number CN219538351U discloses a TCD monitoring head frame with an occipital window as a monitoring site, which connects the forehead component and the fixed component through an adjustable belt. When in use, the forehead component is placed on the patient's forehead, the fixed component is placed on the patient's occipital bone, the third adjustment belt is placed on the top of the patient's head, the first adjustment belt and the second adjustment belt are located on both sides of the patient's head, the TCD probe is combined with the fixed component, and the occipital window is used as the monitoring point to detect the patient.

[0005] Both of the above two existing patent documents adopt a helmet-like wearing method to fix the TCD probe on the patient's head to achieve detection. However, the head shapes of different patients are different. This wearing method requires manual adjustment of the relevant structure each time to suit the patient's head shape, which is cumbersome and inconvenient. In addition, during detection, the probe needs to be moved at different detection acoustic window positions on the patient's head, and this action is difficult to achieve in the above existing patent documents.

[0036] The probe element 208 and the scanning element 209 can be realized by the existing technology and will not be described in detail.

[0037] The linear module mentioned in this solution can adopt the existing electric telescopic rod technology, or the existing screw linear motion technology, etc., which will not be elaborated here.

[0038] Working principle of the present invention: Step 1: Place a stool under the detection member 200 , and the patient sits on the stool with the head located directly under the two vertical plates of the side plate 2061 ; Step 2: The second linear module 215 of the scanning assembly drives the sliding bracket 214 to move, so that the scanning element 209 is close to the patient's head; The first motor 205 drives the rotating shaft 204 to rotate, so that the scanning component rotates around the rotating shaft 204; The second motor 213 drives the gear 212 to rotate, so that the scanning assembly moves on the side plate 2061; The cooperation of the above three can drive the scanning assembly to move around the patient's head, and with the scanning element 209, a three-dimensional model of the patient's head can be obtained. Through existing AI and other technologies, the position of the patient's head to be detected is calculated. The position to be detected refers to the detection acoustic window, and there are multiple ones. This technology is achievable by existing technology and will not be described in detail. Step 3: The first motor 205 drives the rotating shaft 204 to rotate, so that the detection component rotates around the rotating shaft 204; the second motor 213 drives the gear 212 to rotate, so that the detection component moves on the side plate 2061; the second linear module 215 of the detection component drives the sliding bracket 214 to move, so that the probe element 208 is close to the patient's head; the third motor 217 drives the first connecting shaft to rotate, so that the probe element 208 rotates around the first connecting shaft; the fourth motor 219 drives the second connecting shaft to rotate, so that the probe element 208 rotates around the second connecting shaft; Through the cooperation of the above five elements, the end of the probe element 208 can be sequentially fitted with different detection acoustic window positions of the patient. After the fitting is completed, the probe element 208 is started to perform detection. At the same time, similarly, the end of the scanning element 209 of the scanning component can be fitted with the patient's head. Since the human skull is relatively thick and there is no detection acoustic window, during detection, the detection component generally moves on the vertical plate of the side plate 2061. Therefore, the scanning element 209 of the scanning component and the probe element 208 of the detection component can be respectively located on both sides of the patient's head and the center line of the scanning element 209 is close to the center line of the probe element 208. The advantage of this is that during detection, the patient's head can be restricted by the scanning element 209 to prevent the patient's head from unconsciously deviating away from the probe element 208, thereby improving the accuracy of the detection result. Furthermore, the center line of the scanning element 209 is close to the center line of the probe element 208, which can maximize the restriction effect of the scanning element 209.

[0039] In summary, this solution can realize automated TCD detection of patients, and the main focus of medical staff can be on the screen, which greatly reduces the difficulty of detection operation. On this basis, the setting of the scanning component: on the one hand, it can realize the establishment of a three-dimensional model of the patient's head, and with the existing AI and other technologies, it can calculate where the position of the patient's head to be detected is, and the position to be detected refers to the detection acoustic window, and there are multiple detection windows, so as to cooperate with the detection component to realize automated TCD detection; on the one hand, during the detection process, the end of the scanning element of the scanning component can be fitted with the patient's head. Since the human skull is thick, there is no detection acoustic window. Therefore, during the detection, the detection component generally moves on the vertical plate of the side plate. Therefore, the scanning element of the scanning component and the probe element of the detection component can be located on both sides of the patient's head respectively, and the center line of the scanning element is close to the center line of the probe element. The advantage of this is that during the detection, the patient's head can be restricted by the scanning element to prevent the patient's head from unconsciously deviating away from the probe element, thereby improving the accuracy of the detection result. Furthermore, the center line of the scanning element is close to the center line of the probe element, which can maximize the restriction effect of the scanning element.
