Description

Technical Field

[0001] The utility model belongs to the technical field of medical tools, in particular to an assembly verification device for an inner needle tube of a breast rotary cutting probe. Background Art

[0002] The breast excision probe is mainly used in minimally invasive breast excision. It is a minimally innovative technology that combines the three advantages of "painless, minimally invasive, and cosmetic". The breast excision probe passes through a skin incision less than 5 mm and accurately reaches the target lesion under the guidance of ultrasound positioning. Using negative pressure suction, the excision probe sucks the lesion tissue into its collection tank, and then the tissue is removed and transported out of the body through the excision and vacuum transportation system. This process is repeated until the lesion is completely removed under color ultrasound.

[0003] At present, the breast excision probe is composed of an outer needle tube and an inner needle tube. When assembling the breast excision probe, it is necessary not only to verify the length of the outer needle tube of the probe, but also to verify and determine the length of the inner needle tube, so as to facilitate the subsequent assembly of the probe. However, there is currently a lack of an easy-to-operate special device for inner needle tube assembly verification on the market. Therefore, after research and improvement, we propose a breast excision probe inner needle tube assembly verification device. Utility Model Content

[0022] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0023] like Figure 1-3 As shown, the utility model shows an assembly verification device for the inner needle tube of a breast excision probe, which comprises a base plate 1, a slide groove 2 is provided inside the upper end of the base plate 1, a vertical plate 3 with the same width as the base plate 1 is fixedly connected to the upper right end of the base plate 1, a positioning plate 4 is fixedly connected to the middle position of the left side wall of the vertical plate 3 by bonding, a length adapter component 5 is provided at the middle upper end of the vertical plate 3, an assembly verification component 6 is slidably provided on the inner side of the slide groove 2, a first fastening knob 7 and a second fastening knob 8 are respectively installed on the front and rear sides above the assembly verification component 6, and an inner needle tube body 9 is placed in the middle of the upper end of the assembly verification component 6.

[0024] On the basis of the above structure, the bottom plate 1, the vertical plate 3, the positioning plate 4 and the assembly verification component 6 are all made of ABS material.

[0025] In this embodiment, the parts made of ABS material have better processing performance and lower cost.

[0026] Based on the above structure, the length adapter assembly 5 includes a fixed block 51, a screw rod 52 and a connecting frame 53. The fixed block 51 is fixed at the middle position of the upper end of the vertical plate 3. The internal bearing of the fixed block 51 is installed with the screw rod 52, and the connecting frame 53 is provided on the outer threaded sleeve of the left end of the screw rod 52.

[0027] In this embodiment, by controlling the screw rod 52 to rotate, it is convenient to control the connecting frame 53 to drive the assembly verification component 6 to slide and adjust.

[0028] Based on the above structure, the assembly verification component 6 includes an adjustment plate 61, an assembly groove 62 and a limit groove 63. The adjustment plate 61 is snap-fitted and slidably located on the inner side of the slide groove 2. A "concave"-shaped assembly groove 62 is provided in the middle of the upper end of the adjustment plate 61, and the limit grooves 63 are staggered inside the front and rear sides of the adjustment plate 61.

[0029] In this embodiment, the assembly groove 62 is provided to facilitate the stable placement of the inner needle tube body 9.

[0030] On the basis of the above structure, the adjustment plate 61 and the connecting frame 53 are fixedly connected by bolts.

[0031] In this embodiment, the connecting frame 53 is used to facilitate the control of the adjustment plate 61 to stably slide and adjust on the inner side of the slide groove 2 .

[0032] On the basis of the above structure, the threaded sections of the first tightening knob 7 and the second tightening knob 8 respectively penetrate through the two limiting grooves 63 and are threadedly connected to the bottom plate 1 .

[0033] In this embodiment, not only the sliding adjustment range of the adjustment plate 61 can be limited by the first tightening knob 7 and the second tightening knob 8, but also the adjustment plate 61 can be pressed and positioned by tightening the first tightening knob 7 and the second tightening knob 8 after the adjustment of the adjustment plate 61 is completed.

[0034] The working principle of the utility model is as follows:

[0035] When in use, first place the inner needle tube body 9 in the assembly groove 62 opened in the middle of the upper end of the adjustment plate 61, and make the inner needle tube body 9 contact and position with the left end of the adjustment plate 61, then manually rotate the first tightening knob 7 and the second tightening knob 8 to make the two move up slightly and disengage from the upper end surface of the adjustment plate 61, and then manually rotate the screw rod 52 to control the connecting frame 53 to drive the adjustment plate 61 and the inner needle tube body 9 to move right synchronously, until the blade end of the inner needle tube body 9 contacts with the positioning plate 4, stop rotating the screw rod 52, and the length of the inner needle tube body 9 can be verified and determined, which is convenient for the subsequent probe assembly;

[0036] When assembling the inner and outer needle tubes of the subsequent probe, the inner needle tube is directly placed in the middle assembly groove 62 of the adjustment plate 61 after debugging, so as to determine whether the length of the inner needle tube is suitable. The operation is quick and convenient, and the assembly efficiency can be improved. In addition, the two limit grooves 63 and the first tightening knob 7 and the second tightening knob 8 can also be used to limit the sliding adjustment range of the adjustment plate 61. After the adjustment of the adjustment plate 61 is completed, the first tightening knob 7 and the second tightening knob 8 can be tightened to facilitate the pressing and positioning of the adjustment plate 61.

[0037] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
