Description

Technical Field

[0001] The utility model belongs to the technical field of medical tools, in particular to an assembly verification device for an outer 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. The end of the outer needle tube is provided with a suction groove for the lesion tissue. When assembling the breast excision probe, the length of the outer needle tube of the probe needs to be verified first to determine the actual length of the outer needle tube, so that it can be directly assembled in the subsequent assembly process. This plays an important role in improving the assembly efficiency of the breast excision probe. However, there is still a lack of an efficient and easy-to-operate special device for outer needle tube assembly verification on the market. Therefore, after research and improvement, we propose a breast excision probe outer needle tube assembly verification device. Utility Model Content

[0008] As a preferred implementation, a first limiting groove is provided inside the stopper, and the stopper is slidably sleeved on the outer side of the screw rod through the first limiting groove.

[0009] As a preferred embodiment, the assembly verification component includes a fixed sleeve, a connecting frame, an adjustment plate, an assembly groove and a second limit groove. The fixed sleeve is threadedly sleeved on the outside of the screw rod. The outer fixed sleeve of the fixed sleeve is provided with a connecting frame. The connecting frame is located on the left side of the vertical plate. The bottom end of the connecting frame is fixedly connected to the adjustment plate by bolts. An assembly groove equal to the length of the adjusting plate is opened in the middle of the upper end of the adjusting plate. Two of the second limit grooves are staggered inside the front and rear sides of the adjusting plate.

[0010] As a preferred embodiment, the fixing sleeve is located on the right side of the stopper, the longitudinal section of the connecting frame is "L"-shaped and a through groove is provided in the middle of the bottom end thereof.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the solution of the utility model:

[0014] Manually rotate the screw rod to control the fixing sleeve to drive the connecting frame and the adjusting plate to move left synchronously, and then place the outer needle tube body in the assembly groove so that the needle handle part contacts and is positioned with the left end of the adjusting plate. At this time, manually control the stopper to move down and make its bottom end fit into the cutting groove opened at the end of the outer needle tube body, and then turn the butterfly nut to squeeze and push the stopper to move right to the rightmost end of the cutting groove at the end of the outer needle tube body, so as to complete the length verification of the needle tube and determine the actual length. When performing subsequent assembly, you only need to lift the stopper upward to pull out the outer needle tube body. After placing the outer needle tube body in the assembly groove, control the stopper to reset downward to position the outer needle tube body. The operation is convenient and can achieve the technical purpose of efficient assembly.

[0015] The opening of the slide groove and the second limit groove can further improve the state stability of the adjustment plate during the sliding adjustment process. After the adjustment is completed, the first tightening knob and the second tightening knob can be manually tightened to facilitate the compression and positioning of the adjustment plate, which can avoid verification errors caused by the movement of the adjustment plate and ensure the smooth progress of the assembly work after verification.
