Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a breast biopsy puncture positioning cover. Background Art

[0002] Common methods for breast biopsy include incisional biopsy, excisional biopsy, and percutaneous biopsy. For breast lesion patients with complex lesion conditions and suspected malignant lesions, pathological biopsy can be performed to obtain living tissues from the lesion site for diagnosis.

[0003] Percutaneous biopsy includes fine needle aspiration biopsy and core needle biopsy. Using a fine needle or a core needle under the guidance of B-ultrasound, directly puncture the lesion tissue to obtain cells or small pieces of tissue, which can be made into pathological sections and diagnosed through pathological examination. Usually, the diagnostic positive rate is relatively high, which can help patients analyze the lesion situation.

[0004] During breast puncture surgery, the patient is usually in a lying position. Due to different ages of patients, the breasts of some patients will be relatively flaccid. When lying flat, the patient's breasts will show a flat deformation. The breasts with flat deformation are prone to puncture deviation or puncture dislocation during puncture operation.

[0005] In response to the above problems, the prior art CN202010894187- proposed a breast surgery puncture positioning device, which uses a hemispherical airbag-shaped positioning main body to lift and fix the breast, so as to restore its normal shape, facilitate puncture, and facilitate puncture positioning operation through multiple groups of jacks to improve the accuracy of puncture.

[0006] The above solution has good effects of restoring the shape and puncture fixation, but in clinical experiments, it is found that it still has the following problems:

[0007] 1. The positioning main body adopts a hemispherical airbag to contact and fix the breast in all directions, without an open area, which is not convenient for observing the breast, and even less convenient for puncture operation, and increases the manufacturing cost;

[0008] 2. The positioning main body is an integral fixed structure, and the orientation cannot be adjusted according to the actual situation after fixation, which is not convenient for puncture operation;

[0009] 3. The puncture jacks are fixedly arranged in multiple numbers, which can improve the adaptability to a certain extent. However, since they are fixed on the positioning main body and the positioning main body is a fixed structure, their adjustment ability is still limited;

[0010] 4. The air support bag is fixedly arranged on the positioning main body, cannot be flexibly adjusted, and cannot achieve the fixation or massage effect.

[0011] Therefore, it is necessary to propose a puncture locator with a new structure, which can further improve the puncture reliability and stability, and create conditions for improving the surgical efficiency, safety and reducing the surgical cost. Summary of the Invention

[0012] In view of this, the purpose of the present invention is to propose a breast biopsy puncture positioning cover, which can be flexibly adjusted in orientation even after being fixed through special design, facilitating the observation of lesions and puncture operations, so as to solve the problems of inconvenient observation and operation in the prior art.

[0041] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side", "the other side", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention. In addition, terms such as "first", "second", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.

[0042] In addition, terms such as "the same" do not mean that the components are absolutely the same, but there may be slight differences. The term "perpendicular" only means that the positional relationship between components is relatively more perpendicular than "parallel", and does not mean that the structure must be completely perpendicular, but may be slightly inclined.

[0043] Such as Figure 1-7As shown in the figure, an embodiment provided by the present invention: a breast biopsy puncture positioning cover, including a cover body 1, the cover body includes a cover base 2, a pressing block 3 and a puncture table 4 rotatably arranged above the cover base. The cover base includes an annular fixing frame 5 and a pressing airbag 6 arranged inside the fixing frame. An annular groove 7 is arranged on the upper end surface of the fixing frame, and a negative pressure pad (not shown) is arranged in the annular groove on the lower end surface of the fixing frame, which can adsorb on the human skin. The pressing block includes a spherical arc block 8 and a wrapping airbag 9 arranged on the inner wall of the spherical arc block. The spherical arc block is a hemispherical equal-thickness body, and arc-shaped blocks are symmetrically cut off on both sides. The inner arc surface of the arc-shaped block matches the outer surface of the human breast, that is, in the natural state or after the wrapping airbag is inflated, it can form a wrapping state with most breasts. The two ends of the spherical arc block are slidably arranged in the annular groove, so that the contact part between the wrapping airbag and the breast changes, which is convenient for observation and puncture. The puncture table includes a lifting block 10 slidably arranged on the annular groove and a puncture cylinder 11 rotatably arranged on the lifting block through a rotating mechanism. A puncture channel for the puncture needle to pass through is arranged in the puncture cylinder. The lifting block is provided with a lifting push rod 12, which has a lifting function and can raise or retract the puncture cylinder, so as to adjust the height of the puncture cylinder, that is, adjust the puncture height, to adapt to different patients and different conditions. At the same time, the puncture cylinder is arranged on the lifting block through a rotating mechanism, so that the puncture cylinder has a puncture direction adjustment function, and the direction and height of the puncture needle can be freely adjusted.

[0044] Specifically, the rotating mechanism of this embodiment includes a rotating motor 13 fixed on the lifting block, a driving gear 14 fixed on the main shaft of the rotating motor, a support frame 15 fixed on the base of the rotating motor, a rotating shaft 16 rotatably fixed on the support frame, and a driven gear 17 fixed at the end of the rotating shaft and meshed with the driving gear for transmission. A fixing cylinder 18 for disassembling and fixing the puncture cylinder is arranged on the rotating shaft, so that the puncture cylinder and the rotating shaft are arranged in a cross shape. When the rotating motor rotates and drives, it drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, so that the rotating shaft rotates, and then drives the fixing cylinder arranged in a cross shape with the rotating shaft to rotate, so that the puncture cylinder deflects and the angle changes.

[0045] During the puncture operation, the cover base can be fixed to the outer peripheral area of the patient's breast by adsorption through the negative pressure pad first, and then the pressing airbag is inflated through an air filling device to make it expand, the internal space shrinks, and the bottom of the patient's breast is squeezed to lift the tumor mass. After completion, the air filling is stopped, and then the wrapping airbag is inflated to further squeeze a part of the area above the patient's breast, so that the tumor reaches a more natural state and the shape is more stable. Then the inflation is stopped, the position of the mass is checked, the height position of the puncture table is adjusted, and according to the actual orientation of the mass, the angle of the puncture cylinder is adjusted, so as to achieve the desired puncture angle and height. Because the structure is fixed and stable, the puncture orientation remains unchanged all the time, and even multiple repeated operations can be carried out.

[0046] Particularly, the innovation of this embodiment lies in that, due to the rotational setting of the cover body and the cover base, when it is found that the extrusion position is not good, such as not extruding the mass position, the orientation of the cover body can be adjusted at any time to extrude the mass position and expose it fully; when it is found that the puncture space is not the most suitable position, the cover body can also be rotated to make the puncture orientation reach a better direction. In short, through this special design, the exposure is more sufficient, the puncture is more accurate, and the surgical success rate is higher.

[0047] In this embodiment, the support frame is a U-shaped frame. The bottom of the U-shaped frame is fixed to the rotating motor base. Through holes for fixing the two ends of the rotating shaft are provided on the two side walls of the U-shaped frame. Rolling bearings are arranged in the through holes. When the rotating shaft rotates, it can rotate relative to the support frame through the rolling bearings, with little impact on the support frame.

[0048] In this embodiment, a lifting device is arranged on the inner surface of the extrusion block. The lifting device can provide better clamping for the patient's breast, further expose the tumor mass area, and one lifting device is arranged in the upper area of each sliding annular groove, which can conveniently form relatively uniform clamping and fixation of the breast from both sides, making its deformation small and more tending to normal. The lifting device of this embodiment includes a lifting bladder 19 and an extrusion push rod 20 for horizontal movement of the lifting bladder. The rod seat of the extrusion push rod is fixed on the extrusion block, and the lifting bladder is fixed on the telescopic rod of the extrusion push rod. The horizontal position of the lifting device can be adjusted through the extrusion push rod, so as to adapt to breasts of different sizes and improve its adaptability to meet the use of different people.

[0049] In this embodiment, the lifting bladder includes a lifting skeleton arranged in a V shape and an airbag arranged inside the lifting skeleton. The V-shaped arrangement can form limit fixation of the breast from the upper and lower sides, which is beneficial to offset the influence of gravity and facilitate the restoration of the shape.

[0050] In this embodiment, a puncture table is arranged on each side of the extrusion block. If possible, puncture operations can be performed from both sides simultaneously. At the same time, it can also avoid the situation where puncture is not required on the side where a single puncture table is located, thereby improving the operation efficiency.

[0051] In this embodiment, a surgical lamp 21 is arranged on the inner side of the extrusion block. Through the real-time display of the operation area by the surgical lamp, it is convenient for the operator to perform the surgical operation and also avoids the trouble of requiring additional surgical aids.

[0052] In this embodiment, a rotary operation handle 22 is arranged on the top of the extrusion block. The cover body can be rotated through the rotary operation handle, which is more accurate and labor-saving.

[0053] Through multiple clinical experiments, the width of the extrusion block is 50 - 80 mm, which can meet the use of 99% of patients.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
