[0028] In the embodiment provided by the present invention, an adjusting assembly is arranged on the ring bracket. The pressing part of the adjusting assembly can change its position under the drive of the telescopic part, thereby changing the diameter adapted by the ring bracket and improving the versatility of the frame. The following is a specific description.

[0029] Figure 1 Schematic diagram of the frame provided by the embodiment of the present invention. As Figure 1As shown in the figure, the frame body includes an annular bracket 1 and an adjustment assembly 2; the annular bracket 1 is used to sleeved on the in-vivo ultrasonic probe; the adjustment assembly 2 includes a pressing part 20 and a telescopic part 21, the pressing part 20 is arranged inside the annular bracket 1, the first end of the telescopic part 21 is connected to the pressing part 20, and the second end passes through the annular bracket 1 and is thus located outside the annular bracket 1; the telescopic part 21 drives the pressing part 20 to move between a first position and a second position in the radial direction of the annular bracket 1, so that the pressing part 20 clamps the outer wall of the in-vivo ultrasonic probe with the inner wall of the annular bracket 1.

[0030] After the telescopic part 21 drives the pressing part 20 to reach the specified position, the telescopic part 21 can keep the pressing part 20 fixed at this position. When the pressing part 20 moves along the radial direction of the annular bracket 1, the fitting size of the annular bracket 1 can be changed. When the pressing part 20 is in the first position, the diameter of the annular bracket 1 is the largest, and when the pressing part 20 is in the second position, the diameter of the annular bracket 1 is the smallest. The applicable range of the annular bracket 1 is any size between the maximum diameter and the minimum diameter. In use, first sleeve the annular bracket 1 on the outer wall of the ultrasonic probe, and then adjust the position of the pressing part 20 to make the pressing part 20 press the outer wall of the ultrasonic probe, so as to achieve the purpose of relatively fixing the annular bracket 1 and the ultrasonic probe.

[0031] Figure 2 It is a cross-sectional view of the frame body provided by the embodiment of the present invention. As Figure 1 and Figure 2 As shown in the figure, the pressing part 20 is a gasket 201, the first plate surface of the gasket 201 is an arc surface 2011, and the second plate surface is connected to the telescopic part 21. In use, the gasket 201 abuts against the surface of the ultrasonic probe holding part. The shape of the ultrasonic probe holding part is generally cylindrical. Therefore, the first plate surface of the gasket 201 is set to be arc-shaped, and it has a higher degree of fit with the outer wall of the ultrasonic probe, thereby improving the connection stability between the annular bracket 1 and the ultrasonic probe. Further, a friction pad is arranged on the first plate surface. The friction pad is made of a flexible material such as rubber, which can further increase the friction force between the gasket 201 and the ultrasonic probe, making the connection between the frame body and the ultrasonic probe more stable.

[0032] In this embodiment of the present invention, a groove 122 is provided on the inner wall of the annular bracket 1. When the gasket 201 is in the first position, the gasket 201 is placed in the groove 122, and the arc surface 2011 on the gasket 201 forms a continuous annular surface with the inner wall of the annular bracket 1. In this state, the gasket 201 and the annular bracket 1 form a complete annular structure, and the surface of this annular structure is continuous, and it has a higher degree of fit with the outer wall of the connected ultrasonic probe, thereby making the connection between the two more stable.

[0033] Figure 3 It is a schematic structural diagram of the knob part in the frame body provided by the embodiment of the present invention. As Figures 1 to 3As shown in the figure, the telescopic part 21 includes a screw rod 211 and a knob 212; the first end of the screw rod 211 is perpendicularly connected to the second plate surface of the gasket 201, a through hole 121 is provided on the annular bracket 1, and the second end of the screw rod 211 passes through the through hole 121 and is thus located outside the annular bracket 1; the knob 212 is threadedly connected to the screw rod 211, and the knob 212 is located outside the annular bracket 1. The telescopic part 21 realizes telescopic movement through threaded connection. When in use, the knob 212 rotates self-driven to drive the screw rod 211 to move along its axis direction, and the screw rod 211 drives the gasket 201 to move synchronously, thereby driving the gasket 201 to move along the radial direction of the annular bracket 1.

[0034] In the embodiment of the present invention, the knob 212 includes a connecting column 2121, and a threaded hole 2122 penetrating along its axial direction is provided on the connecting column 2121; a first annular protrusion 2123 and a second annular protrusion 2124 are circumferentially provided on the side wall 123 of the connecting column 2121, and the first annular protrusion 2123 and the second annular protrusion 2124 are axially spaced apart along the connecting column 2121; a protruding side wall 123 is provided on the outer wall of the annular bracket 1, the side wall 123 and the outer wall of the annular bracket 1 enclose a clamping groove, the through hole 121 is arranged in the clamping groove, and a limiting baffle 124 is provided at one end of the side wall 123 away from the annular bracket 1; the second annular protrusion 2124 is clamped in the clamping groove, and the limiting baffle 124 is clamped in the interval between the first annular protrusion 2123 and the second annular protrusion 2124. The knob 212 rotates self-driven in the clamping groove to drive the screw rod 211 to move linearly, and the limiting baffle 124 abuts against one side of the second annular protrusion 2124. When the gasket 201 reaches the specified position, the limiting baffle 124 restricts the knob 212 from moving along the axis direction of the screw rod 211, and thus the gasket 201 can be kept fixed at the adjusted position. Preferably, the side wall 123 and the outer wall of the annular bracket 1 enclose a semi-circular clamping groove, and the semi-circular clamping groove includes an insertion opening; the second annular protrusion 2124 is clamped into the semi-circular clamping groove along the insertion opening, and when the second annular protrusion 2124 is clamped with the semi-circular clamping groove, the center of the semi-circular clamping groove, the center of the through hole 121 and the axis of the screw rod 211 coincide. When disassembling and assembling the knob 212, the second annular protrusion 2124 can be clamped into the clamping groove along the insertion opening, and the operation is simple and fast.

[0035] Anti-slip lines are provided on the circumferential surface of the first annular protrusion 2123, and an indication label is provided on one side of the first annular protrusion 2123 away from the second annular protrusion 2124. When operating the knob 212, the anti-slip lines can increase the friction between the knob 212 and the fingers, which is beneficial to the adjustment operation; the indication label plays a prompting role and facilitates the operation of the knob 212. For example, the indication label is a rotation direction indication.

[0036] Figure 4 It is a top view of the screw rod 211 in the frame body provided by the embodiment of the present invention. As Figures 2 to 4As shown in the figure, a limiting plane 2111 is provided on the circumferential surface of the screw 211 along the axial direction of the screw 211; a stop block 1211 that fits the limiting plane 2111 is provided on the through hole 121. When the two are connected, the limiting plane 2111 and the stop block 1211 must be aligned before the screw 211 can be connected into the through hole 121. In this embodiment, the screw 211 is non-cylindrical and the through hole 121 is non-circular, so free rotation cannot be achieved, thus avoiding the self-rotation of the gasket 201.

[0037] In the embodiment of the present invention, the annular bracket 1 includes a symmetric upper bracket 11 and a lower bracket 12. The adjusting assembly 2 is provided on the lower bracket 12, and the lower bracket 12 is used to connect the puncture bracket; the first ends of the upper bracket 11 and the lower bracket 12 are rotatably connected, and the second ends are snap-connected. Among them, the split-structured annular bracket 1 is more conducive to connecting with the ultrasonic probe.

[0038] Figure 5 It is a schematic diagram of the mechanism of the in-vivo ultrasonic probe puncture bracket provided by the embodiment of the present invention. As Figure 5 shown, the in-vivo ultrasonic probe puncture bracket includes the above-mentioned frame body and a needle-piercing structure 3 connected to the frame body. Figure 6 It is a usage state diagram of the in-vivo ultrasonic probe puncture bracket provided by the embodiment of the present invention. As Figure 6 shown, when in use, first sleeved the annular bracket 1 on the holding part 41 of the in-vivo ultrasonic probe 4. If the inner diameter of the annular bracket 1 is greater than the outer diameter of the holding part 41, the two are not stably connected, and relative displacement may occur. Therefore, it is necessary to further fix the in-vivo ultrasonic probe 4. At this time, manually rotate the knob, the knob drives the screw to rotate, and the gasket moves radially along the annular bracket 1 and presses against the outer surface of the holding part 41 of the in-vivo ultrasonic probe 4, thereby realizing the fixed connection between the annular bracket 1 and the in-vivo ultrasonic probe 4.

[0039] The frame body of this structure has high versatility and can be adapted to ultrasonic probes of various sizes, without the need to independently design a matching puncture bracket for each ultrasonic probe, thereby reducing the production cost and usage cost of the puncture bracket.

[0040] The above specific embodiments do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
