At this time, the adjustment of the bracket may adversely affect the position fixation of the ultrasonic probe. Therefore, it is difficult to adjust the bracket during the operation, and it is also easy to affect the image display of the ultrasonic probe. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0030] See also Figure 1-Figure 6 , an ultrasonic probe puncture bracket, comprising a collar 3, used to clamp the periphery of the detection area on the lower side of the probe body 1; an angle adjustment mechanism 6, used to clamp the puncture needle body 2 and adjust the puncture angle of the puncture needle body 2; a disassembly mechanism, used to detachably connect the angle adjustment mechanism 6 to one side of the collar 3;

[0031] The splitting mechanism includes a sleeve rail 4 fixedly connected to one side of the sleeve ring 3, a C-shaped sleeve block 5 is slidably embedded on the surface of the sleeve rail 4, and an angle adjustment mechanism 6 is fixedly connected to the side surface of the C-shaped sleeve block 5;

[0032] The angle adjustment mechanism 6 includes a needle clamping assembly 62 rotatably disposed on one side of the C-shaped sleeve block 5 , and the puncture needle body 2 is clamped inside the needle clamping assembly 62 .

[0033] The above working principle and technical effect are: before operating the probe body 1 to detect the lesion position, the C-shaped sleeve block 5 can be removed from one side of the sleeve rail 4, and the needle clamping assembly 62 that clamps the puncture needle body 2 can be removed together. After the lesion position is detected by the probe body 1, the rotation angle of the needle clamping assembly 62 is adjusted on one side of the C-shaped sleeve block 5 to achieve the purpose of adjusting the puncture angle of the puncture needle body 2. Then, the C-shaped sleeve block 5 is sleeved on one side of the sleeve rail 4 so that the puncture needle body 2 is set on one side of the probe body 1. Finally, the puncture needle body 2 is pushed forward to complete the puncture step.

[0034] Furthermore, the upper and lower surfaces of the sleeve rail 4 are provided with guide grooves 41, and a buckle assembly 42 is also provided. The inner side of the C-shaped sleeve block 5 is provided with buckle teeth 52 that cooperate with the guide grooves 41. The upper and lower surfaces of the C-shaped sleeve block 5 are also provided with buckle grooves 51 that cooperate with the buckle assembly 42.

[0035] By cooperating with the guide groove 41 and the buckle tooth 52, the stability of the C-shaped sleeve block 5 sliding on the sleeve rail 4 is improved, and the clamping part of the buckle assembly 42 is buckled into the position of the buckle groove 51, which is used to fix the position of the C-shaped sleeve block 5 on the sleeve rail 4, so as to fix the position of the puncture needle body 2.

[0036] Reference Figure 5-7 In the previous embodiment: the two sides of the needle clamping assembly 62 are fixedly connected with a rotating column 63, the side surface of the C-shaped sleeve block 5 is provided with a protrusion for rotatably connecting the rotating column 63, the needle clamping assembly 62 includes a rotating sleeve 621 connected to the rotating column 63, and a detachable needle clamping sleeve 622 nested on one side of the rotating sleeve 621, and the inner side of the needle clamping sleeve 622 is provided with a clamping groove for frictionally clamping the puncture needle body 2.

[0037] The above working principle and technical effect are: different needle clamping sleeves 622 are configured with clamping grooves of different widths, and clamping grooves of different widths can be used to clamp puncture needle bodies 2 of different diameters, and the needle clamping sleeve 622 is detachably embedded and connected with the rotating sleeve 621, so that the model of the needle clamping sleeve 622 can be easily replaced on the rotating sleeve 621 to adapt to different models of puncture needle bodies 2.

[0038] Reference Figure 2-8 In the previous embodiment: a fixed rod 65 is also fixedly installed on the surface of the C-shaped sleeve block 5 on one side of which the clamping needle assembly 62 is installed, and an arc plate 64 is fixedly installed on the upper end of the fixed rod 65. The arc plate 64 takes the rotation axis of the rotating column 63 as the center of the circle, and the puncture needle body 2 clamped by the clamping needle assembly 62 is perpendicular to the rotation axis of the rotating column 63. An angle adjustment rod assembly 61 is fixedly installed on the upper side of the clamping needle assembly 62, and an adjustment assembly 66 matched with the arc plate 64 is provided on the side surface of the angle adjustment rod assembly 61. The center of the adjustment assembly 66 is in the same plane as the rotation axis of the rotating column 63;

[0039] The surface of the arc plate 64 is provided with an arc groove 641, and the upper part of the arc groove 641 is marked with an angle scale line 642;

[0040] The adjustment component 66 includes a movable column 661 fixedly connected to one side of the angle adjustment rod component 61. The movable column 661 moves through the arc groove 641 to the back side and is threadedly connected to the movable column 661. A pointer 663 is also provided on the upper side of the movable column 661. The pointer 663 is set on one side of the angle scale line 642.

[0041] The above working principle and technical effect are: after the lesion position is detected by the probe body 1, the Pythagorean theorem can be used to calculate the angle at which the puncture needle body 2 needs to be tilted, and then the position of the movable column 661 is pushed in the arc groove 641, and the pointer 663 indicates the angle scale line 642 for reference, so as to accurately adjust the angle of the puncture needle body 2, and then the nut 662 is rotated to tighten the position of the movable column 661, thereby completing the adjustment of the puncture angle of the puncture needle body 2.

[0042] Reference Figure 2-6 In the previous embodiment: the angle adjustment rod assembly 61 includes a second sliding rod 612 fixedly connected to the upper side of the clamping needle assembly 62, a first support rod 611 is telescopically arranged on the upper side of the second sliding rod 612, and another clamping needle assembly 62 is fixedly connected to the upper end of the first support rod 611, and a limiting slider 613 is also slidably arranged in the second sliding rod 612, and a locking structure is arranged on the limiting slider 613 for locking the position in the second sliding rod 612, and the limiting slider 613 is used to limit the lower position of the first support rod 611.

[0043] The above working principle and technical effect are: after the probe body 1 detects the depth of the lesion, the puncture depth of the puncture needle body 2 is controlled so as to accurately puncture the position of the lesion, which is also difficult.

[0044] The device has the following steps: the upper needle clamping assembly 62 is clamped at the upper end of the puncture needle body 2, and the lower needle clamping assembly 62 is clamped at the lower end of the puncture needle body 2. After the probe body 1 detects the location of the lesion, the depth to which the probe body 1 needs to be inserted can be calculated in advance by the Pythagorean theorem, and then the limit slider 613 is slid to the corresponding position so that the height to which the first support rod 611 descends matches the length to be punctured by the puncture needle body 2. In this way, the difficulty of puncturing the puncture needle body 2 is reduced and the accuracy of puncture is improved.
