(as shown in fig. 3) the connecting block 2.12 is hinged with the slide rail 2.2, and a locking bolt 3 is installed at the hinged position. Because slide rail 2.2 is installed on installation department 2.1 with vertical state, when the handheld ultrasonic probe a of doctor was operated, there may be the problem that slide rail 2.2 influences the doctor's sight, consequently, connecting block 2.12 sets up with slide rail 2.2 is articulated, and slide rail 2.2 can rotate to fix slide rail 2.2 through locking bolt 3, provide a comparatively good operation field of vision for the doctor. And the moving block 2.11 is connected with the connecting block 2.12 through an expansion link 2.13. Because the size of patient is different, bracing piece 1.1 can only be adjusted to probably be fit for patient's height, probably there is slide rail 2.2 and patient too closely, even with the possibility of patient contact, can't use ultrasonic probe a to scan the patient this moment, consequently through telescopic link 2.13, further adjust the distance between slide rail 2.2 and the patient and fix, because the higher operation of therefore convenient doctor of regulation position.

On this basis, in order to further facilitate the disassembly and assembly of the mounting part 2.1, as a specific implementation scheme of the simple disassembly and assembly of the mounting part 2.1, the lower end of the moving block 2.11 is provided with a notch corresponding to the sliding rod 1.2, and a bolt is arranged on the side of the notch arranged on the moving block 2.11. The moving block 2.11 is directly placed on the sliding rod 1.2 through a gap arranged below the moving block, and a bolt is arranged at the gap to buckle the sliding rod 1.2 in order to prevent the moving block 2.11 from falling off from the sliding rod 1.2 in use. When the moving block 2.11 is detached, the installation part 2.1 and the sliding rail 2.2 can be taken down together only by pulling out the bolt and lifting up the moving block 2.11.

For further improving the stability of placing of regulating part 2, every group slide bar 1.2 includes three parallel arrangement's the body of rod, and wherein, two body of rods correspond the setting from top to bottom, and a remaining body of rod sets up the one side at two body of rods. It can be understood that the three rods are arranged in a triangle. The mounting of the moving block 2.11 to the slide bar 1.2 enables an improved stability between the moving block 2.11 and the slide bar 1.2.

Synthesize above-mentioned basic embodiment, for the flexibility ratio that improves doctor's operation ultrasonic probe a, the connection of rotating is provided with on slider 2.3 and rotates piece 2.4 to the articulated installation of control lever 2.5 rotates on piece 2.4. The rotating part 2.4 can also provide the swing of the control rod 2.5 to the two sides of the adjusting part 2, so that the puncture needle can be adjusted along the directions of the two sides of the body of the patient. The further adjustment of the ultrasonic probe a and the puncture needle is facilitated.

Similarly, the control rod 2.5 is a rod-shaped structure with adjustable length, because the patient has an irregular body when lying on the operating table, and the ultrasonic probe a needs to be lifted or dropped continuously when scanning with the ultrasonic probe a. When the ultrasonic probe a is used for scanning, the length of the control rod 2.5 can be changed along with the continuous fluctuation of the ultrasonic probe a on the body of a patient, so that the movement is more flexible, and the inconvenience of the heavier integral up-and-down movement of the adjusting part 2 is avoided.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
