Generally, during diagnosis, the suspicious calcification location is first determined through breast mammography, which is then used to guide the subsequent puncture biopsy. The existing puncture biopsy will use a guided puncture auxiliary device to guide and limit the puncture needle to ensure the puncture accuracy of the puncture needle. However, the radiology breast mammography guided puncture auxiliary device in the existing technology has a slow puncture positioning speed when used, and the shape of the breast where the breast is located is difficult to control during puncture, which will affect the accuracy of the puncture position. Summary of the invention

The arc adjustment plates are provided with three, and the upper end of each arc adjustment plate is respectively connected to an upper arc slider, which is slidably connected to the upper arc guide groove, and the lower end of each arc adjustment plate is respectively connected to a lower arc slider, which is slidably connected to the lower arc guide groove, and the lower arc slider is connected to the support ring through the peripheral side locking assembly; There are three lateral position adjustment mechanisms which are respectively installed on three arc-shaped adjustment plates. Two lateral position adjustment mechanisms close to the arc-shaped support arms are respectively installed with breast control mechanisms, and a lateral position adjustment mechanism away from the arc-shaped support arm is installed with a puncture needle guiding mechanism.

[0005] The support ring is arranged around the breast, and the upper arc guide groove and the lower arc guide groove cooperate with the upper arc slider and the lower arc slider to guide the sliding direction of the arc adjustment plate. The peripheral side locking assembly can lock the position of the lower arc slider, thereby locking the position of the arc adjustment plate. The lateral position adjustment mechanism is used to change the height of the breast shape control mechanism. The breast shape control mechanism is used to control the shape of the breast to avoid the shape change of the breast during puncture. The puncture needle guiding mechanism is used to guide the puncture direction of the puncture needle and determine the puncture position of the puncture needle on the breast.

[0006] Furthermore, the outer peripheral locking assembly includes a locking arc groove, a locking column, a compression spring 1, a friction arc plate and a nut. The outer peripheral side of the support ring is provided with a locking arc groove. The middle part of each lower arc slider is respectively fixedly connected to one end of the locking column. The locking column passes through the locking arc groove, and the end of the locking column away from the lower arc slider is threadedly connected to the nut. The locking column is slidably sleeved with a friction arc plate corresponding to the position of the outer peripheral side of the support ring. The inner side of the friction arc plate is in friction contact with the outer peripheral side of the support ring. The column section of the locking column located between the friction arc plate and the nut is sleeved with a compression spring 1. The nut is used to install the compression spring 1 to prevent the compression spring 1 from being separated from the locking column. The elastic force of the compression spring 1 presses the friction arc plate toward the outer peripheral side of the support ring. The friction force between the outer peripheral side of the support ring and the arc plate can realize the position locking of the lower arc slider in the lower arc guide groove, thereby being able to lock the position of the arc adjustment plate.

[0007] Furthermore, the lateral position adjustment mechanism includes an arc adjustment groove, a lateral adjustment block, a side arc through groove, an arc sliding block and a friction locking assembly. An arc adjustment groove is provided on each arc adjustment plate. Two side arc through grooves are provided on both sides of the arc adjustment plate. A lateral adjustment block is provided in the arc adjustment groove. Two arc sliding blocks are connected to both sides of the lateral adjustment block. The two arc sliding blocks are slidably connected to the two side arc through grooves, and a friction locking assembly is installed on the lateral adjustment block.

[0008] The cooperation between the side arc through groove and the arc sliding block enables the lateral adjustment block to slide stably along the arc adjustment groove, and the friction locking assembly can lock the position of the lateral adjustment block in the arc adjustment groove, thereby changing the height of the lateral adjustment block.

[0009] Furthermore, the breast shape control mechanism includes a push-pull control component, a guide hole, a shape control hard tube and a suction cup. The tops of the two lateral adjustment blocks near the arc-shaped support arm are respectively provided with guide holes. A shape control hard tube is slidably connected in the guide hole. The inner end of the shape control hard tube is fixedly connected with a suction cup. The outer end of the shape control hard tube is connected to the push-pull control component. The push-pull control component is installed in the middle of the outer side of the lateral adjustment block. The push-pull control component is used to push and pull the shape control hard tube to move along the guide hole. When the push-pull control component pushes the shape control hard tube to move toward the inner side of the lateral adjustment block, the breast can be pressed by the suction cup to achieve local compression of the breast. The breast is sucked by the suction cup, and then the push-pull control component pulls the suction cup through the shape control hard tube. The suction cup can pull the local part of the breast. The compression or pulling of the breast can be performed as needed, thereby achieving control of the breast shape, thereby facilitating the improvement of the accuracy of puncture.

[0010] Furthermore, it also includes a negative pressure supply mechanism, the negative pressure supply mechanism includes a valve, a hose, a tee, a supply pipe, a negative pressure box and a negative pressure pump, the outer ends of the two control-shaped hard pipes are connected to one end of the two hoses through two valves, and the other ends of the two hoses are connected to the two ports of the tee respectively, the tee is located in the middle of the upper side of the round cover, the outer side of the arc-shaped support arm is installed with a negative pressure box, the negative pressure box is connected to the air inlet of the negative pressure pump, the negative pressure pump is installed at the bottom of the negative pressure box, the negative pressure box is connected to one end of the supply pipe, and the other end of the supply pipe is connected to the third port of the tee. In order to allow the negative pressure box to be stably pumped with negative pressure, the negative pressure box and the negative pressure pump are connected through a one-way valve, the one-way valve only allows the air in the negative pressure box to be discharged, the negative pressure pump pumps negative pressure into the negative pressure box through the one-way valve, and the valve is opened. The negative pressure box pumps negative pressure into the suction cup through the supply pipe, the tee, the hose and the control-shaped hard pipe, so that the suction cup can absorb the breast, which is convenient for pulling the breast. When the suction cup is needed to squeeze the breast, the negative pressure supply mechanism does not need to work.

[0011] Furthermore, the puncture needle guiding mechanism includes a guiding notch, a guiding shaft, a guiding outer tube and an angle locking assembly. A guiding notch is provided at the top of a lateral adjustment block away from the arc-shaped support arm.

The other end of the positioning column passes through the arc track groove of the arc track and is threadedly connected with a butterfly nut. When the guide outer cylinder moves in the guide notch, the positioning column moves along the arc track groove of the arc track. After the angle of the guide outer cylinder is determined, the butterfly nut is tightened to lock the positioning column with the arc track.

The hexagonal disassembly sleeve facilitates the rotation of the guide replacement inner cylinder, and the guide replacement inner cylinder and the guide outer cylinder are detachably installed, which facilitates the replacement of different guide replacement inner cylinders. During puncture, the puncture needle passes through the guide replacement inner cylinder, and the guide replacement inner cylinder guides and limits the puncture needle, allowing the puncture needle to align with the puncture position and pierce at a suitable angle. After puncture, the guide replacement inner cylinder is easily contaminated, so a new guide replacement inner cylinder can be replaced through the hexagonal disassembly sleeve.

[0014] Furthermore, it also includes an installation and positioning mechanism, which includes a cantilever installation component, a silicone gasket and a double-sided adhesive tape. The cantilever installation component is installed on the top of the round cover, and the bottom of the support ring is provided with a silicone gasket, and a plurality of double-sided adhesive tapes are bonded to the bottom annular array of the silicone gasket.

[0016] Compared with the existing technology, the beneficial effects of this radiology breast mammography guided puncture auxiliary device are: 1. The upper arc guide groove and the lower arc guide groove cooperate with the upper arc slider and the lower arc slider to guide the sliding direction of the arc adjustment plate. The peripheral side locking component can lock the position of the lower arc slider, thereby locking the position of the arc adjustment plate. The lateral position adjustment mechanism is used to quickly change the height of the breast control mechanism.

[0017] 2. The push-pull control component is used to push and pull the shape-controlling hard tube to move along the guide hole. When the push-pull control component pushes the shape-controlling hard tube to move toward the inner side of the lateral adjustment block, the breast can be pressed by the suction cup to achieve local squeezing of the breast. The breast is sucked by the suction cup, and then the push-pull control component pulls the suction cup through the shape-controlling hard tube. The suction cup can pull the local part of the breast. The squeezing or pulling of the breast can be performed as needed, thereby achieving control of the breast shape, thereby helping to improve the accuracy of puncture.

[0018] 3. The guide outer tube can move in the guide notch through the guide shaft, and the angle between the guide outer tube and the breast puncture position can be changed. The angle locking component can lock the angle between the guide outer tube and the breast puncture position.

[0019] 4. With the help of the hexagonal disassembly sleeve, it is convenient to rotate the guide replacement inner cylinder. The guide replacement inner cylinder and the guide outer cylinder can be detachably installed, which is convenient for replacing different guide replacement inner cylinders. During puncture, the puncture needle passes through the guide replacement inner cylinder. The guide replacement inner cylinder guides and limits the puncture needle, allowing the puncture needle to align with the puncture position and pierce at a suitable angle. After puncture, the guide replacement inner cylinder is easily contaminated, so a new guide replacement inner cylinder can be replaced through the hexagonal disassembly sleeve.

The locking column 25 is slidably sleeved with a friction arc plate 27 at a position corresponding to the peripheral side of the support ring 11. The inner side of the friction arc plate 27 is in friction contact with the peripheral side of the support ring 11. The column section of the locking column 25 located between the friction arc plate 27 and the nut 28 is sleeved with a compression spring 26. The nut 28 is used to install the compression spring 26 to prevent the compression spring 26 from being separated from the locking column 25. The elastic force of the compression spring 26 presses the friction arc plate 27 toward the outer peripheral side of the support ring 11. The friction force between the outer peripheral side of the support ring 11 and the arc plate 27 can lock the position of the lower arc slider 23 in the lower arc guide groove 15, thereby locking the position of the arc adjustment plate 21.

[0023] There are three lateral position adjustment mechanisms 3 and they are respectively installed on three arc-shaped adjustment plates 21 . Two lateral position adjustment mechanisms 3 close to the arc-shaped support arm 12 are respectively installed with breast control mechanisms 4 , and one lateral position adjustment mechanism 3 away from the arc-shaped support arm 12 is installed with a puncture needle guiding mechanism 6 .

[0024] The lateral position adjustment mechanism 3 includes an arc adjustment groove 31, a lateral adjustment block 32, a side arc through groove 33, an arc sliding block 34 and a friction locking assembly. An arc adjustment groove 31 is respectively provided on each arc adjustment plate 21. Two side arc through grooves 33 are respectively provided on both sides of the arc adjustment plate 21. A lateral adjustment block 32 is provided in the arc adjustment groove 31. Two arc sliding blocks 34 are respectively integrally formed and connected on both sides of the lateral adjustment block 32.

[0027] The second compression spring 38 pushes the friction cross bar 310, allowing the friction pattern 311 on the friction cross bar 310 to frictionally contact the inner side of the side arc groove 33, thereby locking the position of the lateral adjustment block 32 in the arc adjustment groove 31. When the position of the lateral adjustment block 32 in the arc adjustment groove 31 needs to be changed, the pressing cap 313 is pressed, and the pressing cap 313 squeezes the friction cross bar 310 through the pressing rod 312, and the friction cross bar 310 compresses the compression spring 2 38. At this time, the friction pattern 311 on the friction cross bar 310 is out of contact with the inner side of the side arc groove 33, allowing the lateral adjustment block 32 to move in the arc adjustment groove 31.

When the push-pull control component pushes the shape-controlling hard tube 46 to move toward the inner side of the lateral adjustment block 32, the breast can be pressed by the suction cup 47 to achieve local squeezing of the breast. The breast is sucked by the suction cup 47, and then the push-pull control component pulls the suction cup 47 through the shape-controlling hard tube 46. The suction cup 47 can pull the local part of the breast. The squeezing or pulling of the breast can be performed as needed, thereby achieving control of the breast shape, thereby helping to improve the accuracy of puncture.

The front end of the screw 42 is fixedly connected to the knob 43. The screw 42 is parallel to the control-shaped hard tube 46.

[0030] By rotating the lead screw 42 clockwise through the knob 43, the threaded action of the lead screw 42 and the lead screw nut 44 can drive the shape-controlling hard tube 46 and the suction cup 47 along the guide hole 45 to approach the breast in the auxiliary bracket 1. By rotating the lead screw 42 counterclockwise through the knob 43, the threaded action of the lead screw 42 and the lead screw nut 44 can drive the shape-controlling hard tube 46 and the suction cup 47 along the guide hole 45 to move away from the breast in the auxiliary bracket 1, thereby realizing push-pull control of the shape-controlling hard tube 46.

The outer end of the guiding outer tube 63 is connected to the lateral adjustment block 32 through the angle locking assembly. The guiding outer tube 63 can move in the guiding notch 61 through the guiding shaft 62, and can change the angle between the guiding outer tube 63 and the breast puncture position. The angle locking assembly can lock the angle between the guiding outer tube 63 and the breast puncture position.

[0032] The angle locking assembly includes an arc track 64, a positioning column 65 and a butterfly nut 66.

The center of the circle where the arc track 64 is located coincides with the axis of the guide shaft 62. The outer end side of the guide outer cylinder 63 is fixedly connected to one end of the positioning column 65. The other end of the positioning column 65 passes through the arc track groove of the arc track 64 and is threadedly connected with the butterfly nut 66. When the guide outer cylinder 63 moves in the guide notch 61, the positioning column 65 moves along the arc track groove of the arc track 64. After the angle of the guide outer cylinder 63 is determined, the butterfly nut 66 is tightened to lock the positioning column 65 with the arc track 64. At this time, the angle between the guide outer cylinder 63 and the breast puncture position is also locked.

[0033] The angle locking assembly further includes an angle scale 67 . The outer circumference of the arc track 64 is provided with angle scales 67 at equal angles. The angle scales 67 are used to indicate the adjustment angle of the guide outer cylinder 63 .

The inner side of the guide outer cylinder 63 is threadedly connected with the guide replacement inner cylinder 68, and the outer end of the guide replacement inner cylinder 68 is integrally connected with the hexagonal disassembly sleeve 69. With the help of the hexagonal disassembly sleeve 69, it is convenient to rotate the guide replacement inner cylinder 68. The guide replacement inner cylinder 68 and the guide outer cylinder 63 can be detachably installed, which is convenient for replacing different guide replacement inner cylinders 68. During puncture, the puncture needle passes through the guide replacement inner cylinder 68. The guide replacement inner cylinder 68 guides and limits the puncture needle, allowing the puncture needle to align with the puncture position and puncture at a suitable angle. After puncture, the guide replacement inner cylinder 68 is easily contaminated, so a new guide replacement inner cylinder 68 can be replaced through the hexagonal disassembly sleeve 69.

[0035] When in use, the support ring 11 is arranged around the breast, the upper arc guide groove 14 and the lower arc guide groove 15 cooperate with the upper arc slider 22 and the lower arc slider 23 to guide the sliding direction of the arc adjustment plate 21, and the peripheral side locking assembly can lock the position of the lower arc slider 23, thereby locking the position of the arc adjustment plate 21.
