Because the ultrasonic probe 10 is matched with the couplant for use, and the couplant can influence the marking effect of the marking pen 22, the mounting frame 21 is connected with the auxiliary scraping plate 40, the mounting frame 21 and the auxiliary scraping plate 40 can synchronously move along with the second substrate 32, and the auxiliary scraping plate 40 can be used for erasing the couplant. In this way, the doctor smears the couplant on the body surface of the patient, and inspects the breast of the patient by using the ultrasonic probe 10, after the tumor is detected, the second substrate 32 can rotate around the first substrate 31, the marking component 20 and the auxiliary scraping plate 40 are released, and the couplant in the tumor area is erased by using the auxiliary scraping plate 40; and the auxiliary scraping plate 40 is arranged corresponding to the marking pen 22, so that the marking pen 22 can be used for directly marking the body surface of a patient while erasing the couplant, and the subsequent operation can be conveniently and smoothly carried out. After marking, the marking pen 22 is retracted into the mounting frame 21, and the second base 32 is in running fit with the first base 31, so that the marking assembly 20, the auxiliary scraper 40 and the like can be accommodated.
The auxiliary scraper 40 comprises a first plate 41 and a second plate 43 which are oppositely arranged, and flexible connecting plates 45 are connected to the outer edges of the first plate 41 and the second plate 43. The middle part of the first plate 41 is provided with a first opening 42, and the middle part of the second plate 43 is provided with a second opening 44; the first opening 42 and the second opening 44 are disposed to form a mounting slot. The mounting slot is arranged in the auxiliary scraping plate 40, so that an assembly site is provided for the mounting rack 21, namely, the mounting rack 21 is embedded in the mounting slot, and the marking pen 22 and the auxiliary scraping plate 40 are correspondingly arranged, so that the lump marking can be realized while the couplant is erased. If necessary, a cotton pad or other fleece-like material may be disposed on the side of the second plate 43 remote from the first plate 41 to enhance the wiping effect of the auxiliary scraper 40 on the couplant.
Further, the end of the mounting frame 21 far away from the second base 32 extends into the auxiliary scraper 40 from the first opening 42 in the middle of the first plate 41, and the outer wall of the mounting frame 21 is fixedly connected with the first plate 41, and the end of the mounting frame 21 far away from the second base 32 is folded in the auxiliary scraper 40, i.e. does not extend out from the second opening 44. To ensure stability, the end of the mounting frame 21 remote from the second base 32 abuts the second plate 43.
Thus, when the marker pen 22 is folded inside the mounting frame 21, the marking end of the marker pen 22 is positioned inside the auxiliary scraper 40; while the marker pen 22 is extended from the inside of the mounting frame 21, the marking end of the marker pen 22 is extended from the mounting frame 21 and slightly extended from the second opening 44 of the second plate 43 to the auxiliary scraper 40, and lightly pressed against the body surface of the patient, thereby enabling marking on the skin of the patient.
In addition, when the coupling agent dosage is large, the coupling agent can be set as follows: when the marker pen 22 is not in the ejected state, the second plate 43 is in contact with the body surface of the patient, and the marker pen 22 is not in contact; when the marker pen 22 is in the ejected state, the level of the second plate 43 is relatively higher than that of the marker pen 22. Therefore, the scraper can be used for assisting in moving along a path needing marking and marking at the marking position to remove the body surface couplant, then the marking pen 22 is pressed to pop up from the mounting frame 21 and the mounting slot, and then the ultrasonic probe 10 drives the edge of the marking area to move a second circle to mark the target tumor. In this way, the marker pen 22 and the second plate 43 are not always at the same horizontal position in the process of moving along with the second substrate 32, and the erasing of the couplant and the marking of the tumor are completed in two steps, so that the adverse effect that the marking ink is erased by the second plate 43 after the marker pen 22 marks can be avoided.
In use, the second plate 43 is brought into contact with the patient's skin and moved along the body surface so that the couplant can be applied by the auxiliary blade 40 prior to the ultrasound examination. The second plate 43 pushes the couplant smeared on the body surface to the periphery, so that the couplant is smeared uniformly, and the dosage of the couplant can be reduced.
In addition, when marking the lump region, the auxiliary scraper 40 can be used to erase the couplant, so that the marker pen 22 can conveniently mark the lump region, and the couplant in the marked region can be pushed and coated to other regions to be detected, so that the utilization rate of the couplant is improved.

Further, the second plate 43 has a certain flexibility, and can be bent and deformed, and the flexible connecting plate 45 is arranged, so that the auxiliary scraping plate 40 can deform according to the body shape of the patient when contacting with the body surface of the patient, and can be better attached to the body surface of the patient. The cooperation structure of the first plate body 41 and the second plate body 43 enables the inside of the auxiliary scraping plate 40 to form a space capable of compressing and deforming, particularly, the arrangement of the mounting groove holes enables the auxiliary scraping plate 40 to have enough deformation space and provide more possibility for the deformation direction, and the flexible connecting plate 45 enables the deformation of the auxiliary scraping plate 40 to be more free, so that the abutting pressure of the auxiliary scraping plate 40 on the body surface of a patient is reduced, and the fitting degree of the auxiliary scraping plate 40 and the body surface of the patient is improved; the flexible connecting plate 45 cooperates with the first plate 41 and the second plate 43 to adjust the pressure when the flexible connecting plate is abutted against the body surface, so that the tissue damage of the patient caused by overlarge pressure on the patient can be avoided.
In addition, the cooperation of the first plate 41 and the second plate 43 makes the auxiliary scraping plate 40 have a certain thickness and a certain width, and the contact area between the auxiliary scraping plate 40 and the body surface of the patient can be enlarged in the moving process of the second substrate 32, so that the end part of the second substrate 32 can be ensured to move on the body surface of the patient more stably, the smoothness of the marking process of the marking pen 22 can be ensured, and the marking effect is ensured. The first plate 41 and the second plate 43 cooperate to protect the marker assembly 20, especially the marker pen 22, by the auxiliary scraper 40, especially when the second substrate 32 is received in the assembly groove 33 in the first substrate 31, the marker pen 22 can be protected by the space structure in the auxiliary scraper 40, so as to avoid the contact or scratch between the marker end and the first substrate 31.
The flexible connection plate 45 disposed laterally to the auxiliary blade 40 is provided with a plurality of grooves 46, and the plurality of grooves 46 are disposed in parallel with the second plate 43. Thus, when the auxiliary scraping plate 40 is used for coating or erasing the couplant on the body surface of the patient, when the second plate 43 scrapes the couplant, the redundant couplant can be temporarily stored in the groove 46, so that unclear marks caused by incomplete erasing of the couplant can be avoided. In addition, the grooves 46 formed in the flexible connecting plate 45 are also beneficial to promoting the auxiliary scraping plate 40 to deform and can promote the second plate 43 to locally bend, so that the synchronous deformation of the second plate 43 on the surface curved surface of the breast in the moving process is ensured, the fitting degree is improved, and the cleaning effect of the couplant is ensured.
In addition, when the coupling agent is large in dosage, the second plate 43 is erased for the first time when the coupling agent and the marking of the lump are required to be completed in two steps, and the second plate 43 in the moving process can realize secondary scratch and rub on the surface of the breast sunk into the second opening 44, so that the secondary erasure is realized, the erasing effect of the coupling agent is ensured, and the marking effect of the marking pen 22 is ensured.
