Technical Field

[0001] The present invention relates to the technical field of sampling devices, and more specifically, to a pathological sampling device for breast cancer patients in oncology. Background Art

[0002] The pathological sampling methods for breast cancer mainly include fine needle aspiration biopsy, core needle biopsy, vacuum-assisted biopsy, breast ductoscopy, etc. Puncture biopsy is widely used clinically due to its advantages of small trauma and fast examination speed. The puncture needle is guided by imaging equipment such as ultrasound, X-ray or MRI to achieve rapid sampling.

[0003] However, due to the lack of precise puncture depth control ability of the existing pathological sampling devices for breast cancer patients, insufficient tumor cells cannot be obtained if the puncture is too shallow, and normal tissues are easily over-damaged if the puncture is too deep. Moreover, the sampling steps are usually cumbersome, making it difficult to perform sampling operations quickly and accurately. Summary of the Invention

[0004] The present invention provides a pathological sampling device for breast cancer patients in oncology to solve the problems that the existing pathological sampling devices for breast cancer patients lack precise puncture depth control ability, insufficient tumor cells cannot be obtained if the puncture is too shallow, and normal tissues are easily over-damaged if the puncture is too deep.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A pathological sampling device for breast cancer patients in oncology includes a control cylinder and a distance-determining component. A puncture needle is connected to the bottom end of the control cylinder. A control component is arranged inside the control cylinder. The distance-determining component includes a connecting seat arranged on the outer wall of the control cylinder. A connecting shaft is rotatably clamped on the connecting seat. Both ends of the connecting shaft are commonly connected with a rotating frame. The bottom end of the rotating frame is hinged with a connecting frame. The connecting frame is connected with a sliding plate through an extension component. The bottom end of the sliding plate is hinged with a clamping shaft. The clamping shaft is connected with a fixing ring. The bottom surface of the fixing ring and the bottom end of the puncture needle are arranged on the same horizontal plane.

[0007] Preferably, the control component includes a button slidably clamped at the top end of the control cylinder. A piston is arranged at the bottom end of the button and is connected through a pressure rod. A connecting ring is arranged on the inner wall of the control cylinder. The piston and the connecting ring are connected through a first spring.

[0008] Preferably, a fixing shell is arranged on the outside of the control cylinder. A pressing plate is clamped on the fixing shell. One end of the pressing plate contacts one end of an elastic plate. A wedge-shaped plate is connected to the inner wall of the control cylinder. The top surface of the elastic plate and the bottom surface of the wedge-shaped plate are in planar contact.

[0009] Preferably, the extension component includes sliders connected to both sides of the sliding plate. The two sliders are respectively slidably clamped on both sides of the connecting frame. First wedge blocks are arranged on both sides of the sliding plate, and a pair of second wedge blocks are connected to the bottom end of the connecting frame. The bottom surface of the second wedge block contacts the top surface of the first wedge block.

[0010] Preferably, a plug rod is rotatably clamped in a fixing hole opened on the sliding plate. A knob is coaxially connected to the free end of the plug rod. A pair of traction ropes are connected to the outer side of the plug rod. The free ends of the two traction ropes are both connected to one of the first wedge blocks. Side holes are opened on both sides of the sliding plate. The first wedge block is slidably clamped in the side hole. One end of the first wedge block and the inner wall of the side hole are connected by a second spring.

[0011] Preferably, a notch is opened on the outer wall of the hinge joint between the sliding plate and the card shaft. The width of the notch is slightly smaller than the outer diameter of the card shaft, and the outside of the notch is made of a soft material.

[0012] Preferably, a connecting arm is arranged at the bottom end of the sliding plate. One end of the connecting arm is hinged with a fixed-distance ruler. The fixed-distance ruler and the control cylinder are connected by an adjusting component.

[0013] Preferably, the adjusting component includes a pair of clamping plates arranged on the outer wall of the control cylinder. Orientation blocks are connected to the opposite sides of the two clamping plates. Orientation grooves are opened on both sides of the fixed-distance ruler. The orientation blocks are slidably clamped in the orientation grooves.

[0014] Preferably, a snap button is connected to one end of the fixed-distance ruler. A telescopic rod is arranged on the outer side of the control cylinder. The snap button is clamped in the output end of the telescopic rod.

[0015] Preferably, the telescopic rod is slidably clamped on the outer side of the control cylinder. A magnetic ring is arranged at the output end of the telescopic rod. When the telescopic rod is retracted to the shortest, the magnetic ring is attracted to the outer wall of the control cylinder.

[0016] Principle and beneficial effects of this technical solution:

[0017] (1) In the present invention, the fixed-distance component provided can control the penetration depth of the puncture needle, reduce the operation difficulty during the sampling process, and improve the sampling efficiency at the same time. When using the device for sampling, first select a puncture needle of a suitable specification and combine it with the control cylinder. After the combination is completed, rotate the turntable and the connecting frame outward so that the turntable and the connecting frame rotate towards the direction of the puncture needle. After the sliding plate at the bottom end of the connecting frame is unfolded through the extension component, take a brand-new fixing ring and clamp it to the bottom end of the sliding plate through the notch at the bottom end of the sliding plate. Rotate the fixing ring so that the bottom surface of the fixing ring is parallel to the bottom surface of the puncture needle, and then adjust the angles of the turntable and the connecting frame so that the fixing ring and the bottom end of the puncture needle are on the same horizontal plane.

[0018] (2) The control component provided in the present invention can perform sampling control. Before puncture, push the button slidably clamped at the top of the control cylinder forward, so that the piston connected by the push rod moves downward and pushes out the air in the control cylinder until the elastic plate outside the push rod is clamped at the bottom end of the wedge plate. At this time, puncture can be performed. When the puncture reaches the specified depth, press the pressing plate clamped on the fixed shell, so that the pressing plate compresses the elastic plate in contact with one end of it until the elastic plate is misaligned with the wedge plate. At this time, the push rod where the elastic plate is located will reset under the elastic force of the first spring, so that the puncture needle aspirates the tumor sample.

[0019] (3) The extension component provided in the present invention can adjust the distance between the adjustment sliding plate and the connecting frame. Before puncture, pull the sliding plate down along the connecting frame, so that the second wedge block squeezes the first wedge block along the inclined surface. During the squeezing process, the first wedge block will gradually slide inward along the side hole and compress the second spring until the bottom surface of the second wedge block contacts the top surface of the first wedge block. At this time, the position adjustment of the sliding plate is completed;

[0020] When the device needs to be folded, rotate the knob so that the plug rod coaxially connected to the knob drives the traction rope to move inward, so that the traction rope pulls the two first wedge blocks to compress the second spring. After the second wedge block is misaligned with the first wedge block, the sliding plate can be manually reset. Description of the Drawings

Detailed implementation mode

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and implementation modes:

[0030] Example:

[0031] As Figures 1 to 7 shown, the present invention provides a pathological sampling device for breast cancer patients in oncology, including a control cylinder 1 and a distance measuring component. A puncture needle 2 is connected to the bottom end of the control cylinder 1. A control component is arranged inside the control cylinder 1. The distance measuring component includes a connecting seat 11 arranged on the outer wall of the control cylinder 1. A connecting shaft 6 is rotatably clamped on the connecting seat 11. Both ends of the connecting shaft 6 are jointly connected with a rotating frame 7. The bottom end of the rotating frame 7 is hinged with a connecting frame 21. The connecting frame 21 is connected with a sliding plate 25 through an extension component. The bottom end of the sliding plate 25 is hinged with a clamping shaft 28. The clamping shaft 28 is connected with a fixing ring 3. The bottom surface of the fixing ring 3 and the bottom end of the puncture needle 2 are arranged on the same horizontal plane.

[0032] As Figure 1 and Figure 6 shown, the control component includes a button 29 slidably clamped at the top end of the control cylinder 1. A piston 34 connected through a pressing rod 30 is arranged at the bottom end of the button 29. A connecting ring 32 is arranged on the inner wall of the control cylinder 1. The piston 34 and the connecting ring 32 are connected through a first spring 33.

[0033] As Figure 1 and Figure 6 shown, a fixing shell 37 is arranged on the outside of the control cylinder 1. A pressing plate 36 is clamped on the fixing shell 37. One end of the pressing plate 36 is in contact with one end of an elastic plate 31. A wedge plate 35 is connected to the inner wall of the control cylinder 1. The top surface of the elastic plate 31 and the bottom surface of the wedge plate 35 are in planar contact.

[0034] The control component can perform sampling control. Before puncture, push forward the button 29 that is slidably locked at the top of the control cylinder 1, so that the button 29 moves downward through the piston 34 connected to the pressure rod 30 and pushes out the air in the control cylinder 1, until the elastic plate 31 outside the pressure rod 30 is locked to the bottom end of the wedge plate 35. At this time, puncture can be performed. When the puncture reaches the specified depth, press the pressure plate 36 that is locked on the fixed shell, so that the pressure plate 36 compresses the elastic plate 31 that is in contact with one end thereof, until the elastic plate 31 is misaligned with the wedge plate 35. At this time, the pressure rod 30 where the elastic plate 31 is located will be reset under the elastic force of the first spring 33, so that the puncture needle 2 can aspirate the tumor sample.

[0035] like Figure 4 and Figure 5 As shown, the extension assembly includes sliders 14 connected on both sides of a sliding plate 25. The two sliders 14 are respectively slidably clamped on both sides of a connecting frame 21. A first wedge block 22 is provided on both sides of the sliding plate 25. A pair of second wedge blocks 23 are connected to the bottom end of the connecting frame 21. The bottom surface of the second wedge block 23 contacts the top surface of the first wedge block 22.

[0036] like Figure 4 As shown, a plug rod 17 is rotatably provided in the fixed hole 15 opened on the sliding plate 25, and a knob 18 is coaxially connected to the free end of the plug rod 17. A pair of traction ropes 16 are connected to the outer side of the plug rod 17, and a first wedge block 22 is connected to the free end of the two traction ropes 16. Side holes 24 are opened on both sides of the sliding plate 25, and the first wedge block 22 is slidably clamped in the side hole 24. One end of the first wedge block 22 is connected to the inner wall of the side hole 24 through a second spring 20.

[0037] The extension assembly provided in the present invention can adjust the distance between the sliding plate 25 and the connecting frame 21. Before puncture is required, the sliding plate 25 is pulled down along the connecting frame 21, so that the second wedge block 23 presses the first wedge block 22 along the inclined surface. During the pressing process, the first wedge block 22 will gradually slide inward along the side hole 24 and compress the second spring 20 until the bottom surface of the second wedge block 23 contacts the top surface of the first wedge block 22. At this time, the position adjustment of the sliding plate 25 is completed;

[0038] When the folding device is needed, the knob 18 is turned so that the insertion rod 17 coaxially connected to the knob 18 drives the traction rope 16 to move inward, so that the traction rope 16 pulls the two first wedge blocks 22 to compress the second spring 20, so that the second wedge block 23 is misaligned with the first wedge block 22, and the sliding plate 25 can be manually reset.

[0039] like Figure 5 As shown, a notch 26 is provided on the outer wall of the hinged joint between the sliding plate 25 and the clamping shaft 28. The width of the notch 26 is slightly smaller than the outer diameter of the clamping shaft 28, and the outer side of the notch 26 is made of soft material.

[0040] like Figure 1 , Figure 3 andFigure 5 As shown, a connecting arm 27 is provided at the bottom end of the sliding plate 25. One end of the connecting arm 27 is hinged with a fixed-distance ruler 5, and the fixed-distance ruler 5 is connected to the control cylinder 1 through an adjusting assembly.

[0041] As Figure 1 and Figure 3 shown, the adjusting assembly includes a pair of clamping plates 13 provided on the outer wall of the control cylinder 1. Fixed-direction blocks 12 are connected to the opposite sides of the two clamping plates 13. Fixed-direction grooves 8 are provided on both sides of the fixed-distance ruler 5, and the fixed-direction blocks 12 are slidably clamped in the fixed-direction grooves 8.

[0042] As Figure 1 and Figure 3 shown, a button 4 is connected to one end of the fixed-distance ruler 5, and a telescopic rod 9 is provided on the outside of the control cylinder 1. The button 4 is clamped in the output end of the telescopic rod 9.

[0043] As Figure 1 and Figure 3 shown, the telescopic rod 9 is slidably clamped on the outside of the control cylinder 1. A magnetic ring 10 is provided at the output end of the telescopic rod 9. When the telescopic rod 9 is retracted to the shortest, the magnetic ring 10 is attracted to the outer wall of the control cylinder 1.

[0044] Specific usage method and function of this embodiment:

[0045] The fixed-distance assembly provided in the present invention can control the penetration depth of the puncture needle 2, reduce the operation difficulty during the sampling process, and improve the sampling efficiency at the same time. When using the device for sampling, first select a puncture needle 2 of a suitable specification and combine it with the control cylinder 1. After the combination is completed, rotate the turntable 7 and the connecting frame 21 outward so that the turntable 7 and the connecting frame 21 rotate towards the direction of the puncture needle 2. After the sliding plate 25 at the bottom end of the connecting frame 21 is unfolded through the extension assembly, take a brand-new fixing ring 3 and clamp it to the bottom end of the sliding plate 25 through the notch 26 at the bottom end of the sliding plate 25. Rotate the fixing ring 3 to make the bottom surface of the fixing ring 3 parallel to the bottom surface of the puncture needle 2, and then adjust the angles of the turntable 7 and the connecting frame 21 so that the fixing ring 3 and the bottom end of the puncture needle 2 are on the same horizontal plane;

[0046] During the above adjustment, the fixed-distance ruler 5 hinged to the bottom end of the sliding plate 25 through the connecting arm 27 will slide along the clamping plate 13 provided on the outer wall of the control cylinder 1. First, slide the telescopic rod 9 along the outer wall of the control cylinder 1 so that the axis of the telescopic rod 9 slides to be collinear with the button 4 connected to one end of the fixed-distance ruler 5. When the fixing ring 3 is adjusted in place, record the scale position of the fixed-distance ruler 5 on the clamping plate 13 at this time, and then drive the telescopic rod 9 to extend until one end of the telescopic rod 9 is clamped outside the button 4. At this time, the puncture position and angle can be selected. After the selection is completed, the telescopic rod 9 can be driven to shorten. During the shortening process of the telescopic rod 9, the fixed-distance ruler 5 will slide upward. By observing the sliding distance of the fixed-distance ruler 5, the penetration depth of the puncture needle 2 can be understood. When the specified puncture depth is reached, the shortening of the telescopic rod 9 can be stopped, and the telescopic rod 9 is reset to complete the sampling.
