Detailed Description of the Invention

[0027] The following further explains the present utility model in conjunction with the drawings and specific embodiments. The various drawings of the present utility model are only for illustration to more easily understand the present utility model, and its specific proportions can be adjusted according to design requirements. The up-down relationship of the relative components and the definition of the front / back in the described figures should be understood by those skilled in the art as referring to the relative positions of the components, so they can all be flipped to present the same components, and all of these should belong to the scope disclosed in this specification.

[0028] Reference Figures 1 to 5, embodiments of the present application propose a minimally invasive surgical auxiliary locator for breast masses, including a grip rod 1, an adjustment mechanism 2, two positioning pressing plates 3, and a support plate 5. The adjustment mechanism 2 includes two elastic sheets 21 and an adjustment member 22. One end of the two elastic sheets 21 is fixedly connected and installed in the grip rod 1, and the other ends are away from each other to form an opening. By using the elastic sheets 21 to form the opening, one end of it can be fixedly installed with the grip rod 1, and the size of the opening can be directly adjusted. There is no need to set a movable mechanism at one end of the elastic sheet 21. The interval width between the two positioning pressing plates 3 can be adjusted by adjusting the size of the opening. The structure is simple and practical. The two positioning pressing plates 3 are respectively connected to the two elastic sheets 21 at the end where the opening is formed, and the two positioning pressing plates 3 are arranged at intervals. The adjustment member 22 is installed in the opening formed by the two elastic sheets 21 to adjust the size of the opening and change the interval width between the two positioning pressing plates 3, so as to facilitate changing the interval width between the two positioning pressing plates 3 according to the position and size of the breast mass during use, thereby guiding the puncture of masses in any part and direction, with strong flexibility and increased puncture success rate. The support plate 5 is sleeved outside the grip rod 1 and is located at the connection between the grip rod 1 and the elastic sheet 21. During use, the grip rod 1 is convenient to hold, so as to rotate and move the minimally invasive surgical auxiliary locator for breast masses during use, and the hand can rest against the support plate 5 to facilitate pressing and fixing the local gland and skin of the breast, which is convenient to use and has a good fixing effect. The utility model can play an auxiliary positioning role in the operations of positioning masses and performing punctures. For example, it can position masses during percutaneous biopsy and during breast resection surgery. Percutaneous biopsy is to insert a puncture needle into the breast mass under ultrasound guidance and take out the diseased tissue for pathological examination to make a clear diagnosis. Breast resection surgery is to perform a positioning puncture to place the cutting needle directly below the mass and then perform the resection surgery immediately.

[0029] In a specific embodiment, referring to Figure 1 and Figure 2 , the elastic sheet 21 includes a first arc segment 211 and a vertical segment 212. One of the first arc segments 211 bends upward from right to left, and the other first arc segment 211 bends upward from left to right, and the convex surfaces of the two first arc segments 211 are arranged opposite to each other. One end of each of the two first arc segments 211 is fixedly connected to the grip rod 1, and the other ends are respectively connected to the two vertical segments 212. The two vertical segments 212 are arranged in parallel, so that the structure of the elastic sheet 21 is similar to a U-shaped structure. Further, the adjustment member 22 is installed on the two vertical segments 212. The vertical segment 212 is connected to the positioning pressing plate 3.

[0030] In a specific embodiment, referring to Figure 1 , Figure 3 and Figure 4, the positioning pressing piece 3 is a metal piece. To avoid damaging the local mammary glands and skin, a silica gel sleeve 6 is sleeved on the positioning pressing piece 3, and the wide surface of the positioning pressing piece 3 contacts the local mammary glands and skin. The width range of the positioning pressing piece 3 is 0.5 cm to 2 cm. Specifically, the positioning pressing piece 3 includes a second arc section 31 and a third arc section 32. The second arc section 31 bends downward from back to front, one end of the second arc section 31 is connected to the vertical section 212, and the other end is connected to the third arc section 32. The third arc section 32 is an arched structure with a convex middle part from back to front. The positioning pressing piece 3 adopts an arc structure to facilitate increasing the contact area between the positioning pressing piece 3 and the local mammary glands and skin, reducing the pressure on the glands and skin per unit area, reducing the discomfort of the patient, and ensuring the positioning effect.

[0031] In a specific embodiment, referring to Figure 2 and Figure 5 , it further includes a guiding outer rod 41 and a guiding inner rod 42. The adjusting member 22 includes an adjusting screw 221, an adjusting nut 222, and an adjusting knob 223. One end of the adjusting screw 221 is rotatably installed on one of the vertical sections 212 and fixedly connected to the adjusting knob 223. The other end of the adjusting screw 221 penetrates through the other vertical section 212 and is screwed with the adjusting nut 222. By rotating the adjusting knob 223, the adjusting screw 221 is driven to rotate, so that the adjusting nut 222 moves away from or close to the adjusting knob 223 to increase or decrease the distance between the two vertical sections 212, adjust the opening size, and thus change the interval width between the two positioning pressing pieces 3. The guiding outer rod 41 and the guiding inner rod 42 are respectively fixedly connected to the two vertical sections 212, and the guiding inner rod 42 is slidably installed in the guiding outer rod 41 to facilitate the stable movement of the vertical sections 212 and the positioning pressing pieces 3 when adjusting the opening size and improve the stability of the minimally invasive surgical auxiliary locator for breast tumors.

[0032] The minimally invasive surgical auxiliary locator for breast tumors will be further elaborated with a specific usage process:

[0033] During ultrasound-guided breast puncture biopsy, place the breast tumor under the minimally invasive surgical auxiliary locator for breast tumors, referring to Figure 2 , rotate the adjusting knob 223 to adjust the opening formed by the two elastic pieces 21, so as to adjust the interval width between the two positioning pressing pieces 3. Hold the grip rod 1 by hand and press against the support plate 5, press towards the chest wall direction to fix the local mammary glands and skin, and the ultrasound probe performs real-time scanning between the two positioning pressing pieces 3 to solve the problem that the tumor in the gland moves, resulting in difficult puncture and the need for repeated punctures. When in use, hold the grip rod 1 by hand and move the minimally invasive surgical auxiliary locator for breast tumors to drive the two positioning pressing pieces 3 to rotate and move arbitrarily, so as to guide the puncture of tumors in any part and direction, increase the puncture success rate, and reduce the iatrogenic injury caused by repeated punctures.

[0034] The above embodiments are only used to further illustrate the technical solutions of the present invention, but the present invention is not limited to the embodiments. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solutions of the present invention.
