Detailed ways

Reference herein to an embodiment means that a particular feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those skilled in the art understand, both explicitly and implicitly, that the embodiments described herein may be combined with other embodiments.

Example 1

An ultrasonic puncture fixing structure and ultrasonic puncture biopsy device, as shown in Figures 1 to 4, include a probe 1, a box 2, a box cover 3 and a needle slot 4. A "T" is fixed on the side of the probe 1 through bolts. Font-shaped box 2, the narrow part of the box 2 is close to the holding position of the probe, the outside of the box 2 is hinged with a box cover 3 that can be rotated and opened, and the bottom of the box 2 is provided with a needle slot on the same side as the detection direction of the probe 1 4. The needle slot 4 is composed of a plurality of interconnected circular slots and extends outward for a distance. It also includes an adjustment block 5, an electric push rod 6 and a needle 7. A hollow structure is movably installed in the box 2. Adjusting block 5, the electric push rod 6 is installed inside the adjusting block 5 through bolts. The fixed part of the electric push rod 6 is fixedly connected to the adjusting block 5 through bolts. The movable part of the electric push rod 6 is connected to the needle 7. The electric push rod 6 can Drive the needle to make reciprocating linear motion.

As shown in Figure 3, it also includes a pressure block 8 and an elastic member 9. The pressure block 8 passes through the top surface of the box 2. The bottom end of the pressure block 8 is fixedly connected to the adjustment block 5 through strong glue bonding. The adjustment block There is an elastic member 9 connected between 5 and the box body 2. There are two groups of elastic members 9 and both are made of stainless steel compression springs.

As shown in Figure 5, it also includes a guide column 10 and a movable block 11. The guide column 10 is symmetrically installed on both sides of the box 2 by welding. The guide column 10 is perpendicular to the side of the probe 1. The guide column 10 is formed by a cylinder. It consists of two parts: the sphere at the end of the guide column 10 and the diameter of the sphere at the end of the guide column 10 is slightly larger than the cylinder. The movable block 11 is slidably installed between the two guide columns 10 and can move along the direction of the guide column 10 .

As shown in Figure 6, a wedge-shaped block 12 is also included. The wedge-shaped block 12 is provided on the movable block 11. The top of the wedge-shaped block 12 is a slope.
