When inserted, the edge of the limit block 35 is arc-shaped, thereby pushing the limit blocks 35 on both sides to move into the first movable groove 31, squeezing the first spring 34, causing the first spring 34 to deform. After the ultrasonic probe 2 is completely attached to the connecting port of the fixing seat 1, under the rebound action of the first spring 34, the first movable block 32 drives the limit block 35 to attach to the surface of the ultrasonic probe 2, thereby fixing the ultrasonic probe 2.

[0022] Furthermore, an adjustment component 4 is provided between the fixed seat 1 and the marking pen 5. The adjustment component 4 includes a slide groove 41, a slider 42, a second connecting rod 43 and a pen ring 44. The right side of the fixed seat 1 is provided with a slide groove 41. Three groups of sliders 42 are slidably connected in the slide groove 41. The outer sides of the three groups of sliders 42 are respectively provided with second connecting rods 43. The outer ends of the second connecting rods 43 are fixedly connected to the pen ring 44. The pen ring 44 is inserted with the marking pen 5.

[0023] Furthermore, a movable assembly 6 is provided in the slider 42, and the movable assembly 6 includes a second movable groove 61, a second movable block 62, and a second spring 63.

Figure 7 As shown, when the structure is used to mark the skin surface with a marking pen 5, due to the uneven skin surface, it is impossible to ensure that the marking pen 5 is in real-time contact with the skin during movement, and disconnection is likely to occur. Under the elastic action of the second spring 63, the second movable block 62 is pushed to move up and down in the slider 42, so that the marking pen 5 is in full contact with the skin and damage to the skin is avoided.

[0024] Furthermore, a positioning assembly 7 is provided at the top of the slider 42, and the positioning assembly 7 includes a third connecting rod 71, a fixing block 72 and a positioning ring 73.

[0025] Furthermore, the outer ends of the two groups of first connecting rods 33 are respectively fixedly connected with two groups of fixing rings 14, and the fixing rings 14 are located at the front and rear sides of the ultrasonic probe 2. Figure 3 As shown, the structure is used to facilitate placing the thumb and index finger into the two sets of fixing rings 14 respectively through the fixing rings 14, so as to facilitate moving the device and avoid it from falling off the hand. At the same time, the first connecting rod 33 is conveniently pulled through the two sets of fixing rings 14 to drive the first movable block 32, so that the inner side of the limit block 35 is separated from the outer surface of the ultrasonic probe 2, thereby canceling the fixation of the ultrasonic probe 2.

[0026] Furthermore, the outer side of the pen ring 44 is threadedly connected with a positioning bolt 15, and the inner end of the positioning bolt 15 is connected to the inside of the pen ring 44. Figure 5 As shown, the structure is used to adjust the tightness of the marking pen 5 in the pen ring 44 by rotating the positioning bolt 15, so as to facilitate the replacement of the marking pen 5.

[0027] Working principle: When used, Figure 1 and Figure 6As shown, firstly, the ultrasonic probe 2 is clamped with the fixing seat 1, and the ultrasonic probe 2 is inserted into the connection port of the fixing seat 1. When the ultrasonic probe 2 is inserted, the edge of the limit block 35 is arc-shaped, so when the ultrasonic probe 2 is pushed inward, the limit blocks 35 on both sides move into the first movable groove 31, and the first spring 34 is squeezed to deform the first spring 34. When the ultrasonic probe 2 is completely attached to the connection port of the fixing seat 1, the first movable block 32 drives the limit block 35 to attach to the surface of the ultrasonic probe 2 under the rebound action of the first spring 34, and the ultrasonic probe 2 is fixed. After the ultrasonic probe 2 is adjusted, as shown in FIG. Figure 2 and Figure 3 As shown, the display panel 9 is turned on by controlling the button 10, and during the movement of the ultrasonic probe 2, as shown in FIG. Figure 4 As shown, three groups of marking pens 5 are used to mark different blood vessels, and the pen ring 44 can be slid in the slide groove 41 through the slider 42 according to the position of the blood vessel to adjust the position of the marking pen 5, such as Figure 5 As shown, when the marking pen 5 needs to be fixed, the positioning ring 73 can be rotated, and the positioning ring 73 is threadedly connected with the third connecting rod 71, so that the positioning ring 73 fits the surface of the fixing seat 1, and the slider 42 is limited, so as to fix the position of the marking pen 5. Figure 7 As shown in the figure, when the marking pen 5 marks on the skin surface, due to the uneven skin surface, it is impossible to ensure that the marking pen 5 is in real-time contact with the skin during the movement, and it is easy to be disconnected. Under the elastic action of the second spring 63, the second movable block 62 is pushed to move up and down in the slider 42, so that the marking pen 5 is fully in contact with the skin and avoids causing damage to the skin. Figure 2 As shown, the movement trajectory of the ultrasonic probe 2 is synchronously calibrated by the marking pen 5 and the micro-marking transmitter 13, the vascular data of the ultrasonic probe 2 is received, the vascular image information is converted into coordinate data by the built-in algorithm, the direction and position of the blood vessel are analyzed, and the corresponding marking instructions are generated after the processed vascular coordinate data, and the micro-marking transmitter 13 is controlled to mark, and the position and path of the blood vessel are accurately marked in cooperation with the marking pen 5, and then the marked vascular path is presented on the display panel 9, and at the same time, the operation instructions input by the doctor through touch or button are received, the marking function is adjusted, and the vascular path data marked each time is stored in the local storage unit, and the data can be transmitted with external devices wirelessly or wiredly. The above is the entire working principle of the present invention.
