[0002] Breast surgery is a branch of clinical surgery, mainly focusing on the surgical aspects of breast diseases. The breast is located between the superficial and deep layers of the subcutaneous superficial fascia, and breast lumps are a common breast disease. When treating breast lumps, it is necessary to use a puncture needle to puncture the lump to obtain a specimen, and the specimen is used for pathological diagnosis and confirmation. During the puncture, an auxiliary positioning puncture device is required.

[0003] In the existing breast puncture surgery, the puncture device is generally used to manually puncture the part that needs to be punctured. During the puncture process, the hand will shake slightly, which affects the accuracy of the puncture. During the puncture, due to different requirements for puncture at different positions, the insertion depth of the puncture needle will be different. At the same time, there are certain requirements for the puncture angle. When medical staff puncture the patient's breast, it is difficult to control the puncture depth of the puncture needle and the puncture angle. The puncture position is not accurate, which will affect the puncture effect. For this reason, we propose a breast auxiliary treatment positioning puncture device. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example

[0040] See also Figure 1-Figure 11 The present invention provides the following technical solutions: a breast auxiliary treatment positioning puncture device, comprising a support seat 1 and a puncture needle 10. An angle adjustment component 2 is arranged on the outside of the support seat 1. The angle adjustment component 2 comprises a fixed seat 201. An electric push rod 3 is fixedly connected to the front of the fixed seat 201. A fixed frame 4 is fixedly connected to the end of the electric push rod 3 away from the fixed seat 201.

[0041] A limiting frame 8 is fixedly connected to the middle of the upper surface of the fixing frame 4 , a housing 9 is slidably mounted inside the limiting frame 8 , and a puncture needle 10 is fixedly mounted on the front side of the housing 9 .

[0042] A clamping assembly 5 for limiting the movement of the puncture needle 10 in the fixing frame 4 is installed on the fixing frame 4 , wherein the clamping assembly 5 includes two brackets 501 , two connecting rods 502 and two L-shaped clamps 503 , and the two L-shaped clamps 503 are adapted to the surface of the shell 9 .

[0043] The two brackets 501 are fixedly mounted on both sides of the upper surface of the fixing frame 4 , respectively. The connecting rod 502 is inserted into the inside of the bracket 501 , and the L-shaped clamping plate 503 is fixedly mounted on the upper end of the connecting rod 502 .

[0044] A slide groove 504 is provided on the lower surface of the fixed frame 4, a slider 505 is slidably installed inside the slide groove 504, and the lower end of the connecting rod 502 is fixedly connected to the slider 505; a threaded rod 506 is threadedly connected to the inner part of the connecting rod 502, and a handle ring 507 is fixedly connected to the middle part of the threaded rod 506.

[0045] During specific use, through the setting of the clamping assembly 5, the handle ring 507 is rotated to rotate the threaded rod 506, the slider 505 moves inside the slide groove 504, and the connecting rod 502 slides inside the bracket 501. The double limit can prevent the connecting rod 502 from being easily displaced when moving, thereby ensuring the smooth movement of the L-shaped clamping plate 503 and clamping the shell 9 more firmly. When the electric push rod 3 pushes the fixed frame 4 to move, the puncture needle 10 can be punctured. During the puncture process, the puncture needle 10 does not shake, thereby improving the accuracy of the puncture.

[0046] The two brackets 501 are respectively fixedly installed on both sides of the upper surface of the fixed frame 4 and fixedly connected to the corresponding limiting tube 6. The connecting rod 502 is inserted into the inside of the bracket 501, and the L-shaped clamp 503 is fixedly installed on the upper end of the connecting rod 502; the fixing column 705 is L-shaped, and the end of the fixing column 705 away from the limiting tube 6 is fixedly connected to the connecting rod 502.

[0047] The surface of the fixed frame 4 is fixedly connected with a limiting tube 6 , and the two brackets 501 are fixedly connected with the corresponding limiting tubes 6 , and the interior of the limiting tubes 6 is plugged with a needle insertion adjustment component 7 .

[0048] Among them, the needle insertion adjustment component 7 includes a blocking frame 701, which is inserted into the interior of the limiting tube 6. A limiting hole 702 is opened on the front of the blocking frame 701, and the puncture needle 10 passes through the limiting hole 702. Several positioning holes 703 are opened on both sides of the blocking frame 701. A fixing column 705 is inserted on the side surface of the limiting tube 6. The fixing column 705 is L-shaped, and the end of the fixing column 705 away from the limiting tube 6 is fixedly connected to the connecting rod 502. When the clamping assembly 5 limits the puncture needle 10 from moving in the fixed frame 4, the fixing column 705 can be plugged into and matched with the corresponding positioning hole 703.

[0049] When in use, before the clamping assembly 5 clamps the housing 9, the needle insertion adjustment assembly 7 can be used to control the movement of the retaining frame 701 inside the limiting tube 6 according to the required needle insertion depth. According to the prompt of the scale bar 704, the retaining frame 701 is adjusted to the required position. After the clamping assembly 5 clamps the housing 9, the L-shaped clamping plate 503 moves, which drives the fixing column 705 to move, so that the fixing column 705 is plugged into the positioning hole 703 corresponding to the side surface of the retaining frame 701, and the retaining frame 701 is adjusted to the required position by using the fixing column 705. 1 is used to fix the position. When the puncture needle 10 is used for puncture, the movement of the puncture needle 10 is restricted when the blocking frame 701 contacts the human body, so the puncture depth of the puncture needle 10 can be effectively controlled. On this basis, a pressure sensor can be arranged inside the blocking frame 701, and the pressure sensor is electrically connected to the electric push rod 3. The pressure sensor is used to detect the pressure applied to the blocking frame 701 when it contacts the human body. When the pressure detected by the pressure sensor reaches a set value, the pressure sensor sends an electrical signal to the electric push rod 3 to stop the pushing action of the electric push rod 3.

[0050] In addition, a U-shaped card frame 11 is fixedly installed on the lower surface of the support seat 1, and the internal thread of the U-shaped card frame 11 is connected to a threaded column 12, the top end of the threaded column 12 is fixedly connected to a handle 13, and the bottom end of the threaded column 12 is fixedly connected to a circular pressure plate 14.

[0051] During specific use, the device can be clamped on the bed through the setting of the U-shaped clamping frame 11. Through the setting of the handle 13 and the circular pressure plate 14, after the U-shaped clamping frame 11 is clamped on the bed, the staff twists the handle 13 to control the threaded column 12 to rotate, so that the circular pressure plate 14 moves downward and contacts the bed, making the connection between the U-shaped clamping frame 11 and the bed more firmly.

[0052] After the support seat 1 is fixed, the angle of the puncture needle 10 is adjusted by the angle adjustment component 2, wherein a positioning column 202 is arranged inside the support seat 1, the positioning column 202 extends to both sides of the support seat 1, and the fixed seat 201 is rotatably mounted on the surface of the positioning column 202, one end of the positioning column 202 is fixedly connected to the limiting disk 203, and an arc-shaped hole 204 is opened on the surface of the limiting disk 203.

[0053] Limiting posts 205 are disposed on both sides of the fixing seat 201 . The limiting posts 205 are inserted into the arc-shaped holes 204 , and a locking cap 206 is threadedly connected to the outer surface of one end of the limiting posts 205 away from the fixing seat 201 .

[0054] During specific use, when it is necessary to roughly adjust the angle of the puncture needle 10, the positioning column 202 and the support seat 1 are in a relatively fixed state, and the locking cap 206 has not yet pressed against the limit plate 203. At this time, the fixed seat 201 can be rotated on the surface of the positioning column 202, and the fixed seat 201 is rotated to a suitable angle, and then the locking cap 206 is rotated, and the locking cap 206 is used to press against the limit plate 203. At this time, the fixed seat 201 and the positioning column 202 can be fixed together, thereby completing the coarse adjustment of the angle of the puncture needle 10.

[0055] Furthermore, the positioning column 202 is rotatably installed inside the support seat 1, and a cavity 101 is provided inside the support seat 1, and an inner gear ring 102 is fixedly provided inside the cavity 101; a limiting gear ring 103 is axially slidingly provided on the surface of the positioning column 202 located in the cavity 101, and a tooth portion 1031 is provided on the surface of the limiting gear ring 103, and when the limiting gear ring 103 moves axially, the tooth portion 1031 can engage with the inner gear ring 102.

[0056] The limiting column 205 is axially slidably installed inside the fixed seat 201. The surfaces of the support seat 1 and the limiting gear ring 103 are both provided with an arc hole 204. The limiting column 205 passes through the arc hole 204 on the surface of the limiting gear ring 103. Two retaining rings 2051 are provided on the surface of the limiting column 205. The two retaining rings 2051 are located on both sides of the limiting gear ring 103. A spring is provided between the retaining ring 2051 and the fixed seat 201.

[0057] The angle adjustment assembly 2 also includes a fine-tuning structure, wherein the fine-tuning structure includes an inner rod 207 and an adjusting gear 2071. The inner rod 207 is rotatably installed inside the limiting column 205, and both ends of the inner rod 207 extend out of the two ends of the limiting column 205. The adjusting gear 2071 is fixedly arranged at one end of the inner rod 207 located inside the cavity 101. When the limiting column 205 drives the tooth portion 1031 to separate from the inner tooth ring 102 through the retaining ring 2051, the adjusting gear 2071 can engage with the inner tooth ring 102. When the tooth portion 1031 is separated from the inner tooth ring 102, the fine-tuning structure is used to fine-tune the angle of the fixed seat 201.

[0058] During specific use, after the puncture needle 10 is roughly adjusted, the puncture needle 10 is continued to be fine-tuned to accurately adjust the puncture angle of the puncture needle 10. Specifically, on the basis of the above-mentioned rough adjustment, the locking cap 206 is continued to be rotated, and the locking cap 206 is engaged with the thread of the limit column 205, and the limit column 205 is continued to move outward, and the spring between the retaining ring 2051 and the fixed seat 201 is further compressed. The movement of the limit column 205 will drive the limit gear ring 103 and the adjusting gear 2071 to move together through the retaining ring 2051 until the tooth portion 1031 on the surface of the limit gear ring 103 is separated from the inner gear ring 102, and the adjusting gear 2071 is engaged with the inner gear ring 102. At this time, the inner rod 207 is rotated, and the inner rod 207 drives the adjusting gear 2071 to engage with the inner gear ring 102, driving the fixed seat 201 to rotate at a micro-angle relative to the support seat 1, thereby achieving fine adjustment of the puncture angle of the puncture needle 10.

[0059] The working principle and use process of the present invention:

[0060] The medical staff can first place the shell 9 inside the limit frame 8, and then control the blocking frame 701 to move inside the limit tube 6 according to the required needle insertion depth, and adjust the blocking frame 701 to the required position according to the prompt of the scale bar 704, and then rotate the handle ring 507 to rotate the threaded rod 506, thereby moving the two connecting rods 502, and the two L-shaped clamps 503 are close to each other to clamp and fix the shell 9, and during the movement of the L-shaped clamp 503, the fixed column 705 is driven to move, and the fixed column 705 is plugged into the corresponding positioning hole 703 to complete the positioning adjustment of the puncture depth of the puncture needle 10.

[0061] Then, the handle 13, the threaded column 12 and the circular pressure plate 14 are used to fix the puncture device at a suitable position on the bed. After that, the puncture angle of the puncture needle 10 can be roughly adjusted and finely adjusted in turn by rotating the locking cap 206 to accurately adjust the puncture angle of the puncture needle 10.

[0062] After the puncture angle of the puncture needle 10 is adjusted, the medical staff starts the electric push rod 3, which can drive the fixed frame 4 to move, and use the puncture needle 10 to puncture into the patient's body. With the cooperation of the above-mentioned structure, no shaking will occur during the puncture process, and the stability is better. In addition, due to the setting of the retaining frame 701, the puncture depth of the puncture needle 10 can be effectively controlled, so that the puncture accuracy is better and the puncture effect is better.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
