Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a puncture sampling device for oncology departments. Background Art

[0002] Tumors are diseases that seriously endanger human health and life. In recent years, the incidence rate has been gradually increasing, and the age of onset has been gradually decreasing. Early detection, correct diagnosis, and timely treatment have an important impact on the prognosis. With the continuous improvement of examination means and methods, the diagnostic accuracy rate has gradually increased. However, there is still a large proportion of tumors that do not have typical imaging characteristics, making diagnosis difficult. Correct diagnosis requires the combination of clinical, imaging, and pathology. Among them, pathological diagnosis plays a key role in the selection of treatment plans. The puncture biopsy technique is the main way to obtain pathological diagnosis;

[0003] Most of the existing puncture sampling devices perform punctures manually during puncture, which is not convenient for puncturing at the required angle and is prone to angle deviation during puncture. Moreover, when the amount of the sample is large in the existing technology, it is not convenient to divide and pack the sample, and the operation of replacing the sampling collection bottle is complicated and needs to be improved. For this reason, we have proposed a puncture sampling device for oncology departments. Summary of the Invention

[0004] Object of the Invention: The object of the present invention is to provide convenience for automatically adjusting the puncture angle; another object of the present invention is to provide convenience for dividing and collecting.

[0005] Technical Solution: A puncture sampling device for oncology departments includes a bottom plate. A vertical rod is fixedly connected to the upper surface of the bottom plate. The top end of the vertical rod is fixedly connected with a first concave member. The inner side of the first concave member is rotationally connected with a rotating head through a rotating shaft. The top of the rotating head is fixedly connected with a collar. The inner side of the collar is slidably connected with a suction syringe;

[0006] A mounting seat is fixedly connected to the right side of the outer side wall of the suction syringe. A motor is fixedly connected to the right side of the mounting seat. The left end of the output shaft of the motor is fixedly connected with a screw rod to the left of the mounting seat. The left end of the screw rod penetrates to the left of the rotating head and is threadedly connected with the rotating head;

[0007] An electric push rod is fixedly connected to the left side of the vertical rod. The top end of the output end of the electric push rod is fixedly connected with a connecting head. A second concave member is fixedly connected to the left side of the rotating head and outside the connecting head. Through-type connecting grooves are formed on both the front surface and the rear surface of the second concave member. Connecting columns are fixedly connected to both the front surface and the rear surface of the connecting head and inside the two connecting grooves;

[0008] A liquid discharge port is integrally formed on the left side of the outer side wall of the suction syringe.

[0009] The lower surface of the bottom plate is fixedly connected with an anti-slip pad.

[0010] Furthermore, a turntable is rotatably connected to the upper surface of the bottom plate and to the left of the vertical rod through a rotating shaft, and a plurality of placement openings are formed in the upper surface of the turntable.

[0011] Furthermore, a plurality of wedge-shaped extrusion blocks are integrally formed on the outer side wall of the turntable. The number of the plurality of wedge-shaped extrusion blocks is the same as the number of the plurality of placement openings, and the positions correspond one by one.

[0012] Furthermore, a contraction box is fixedly connected to the upper surface of the bottom plate and in front of the turntable. An L-shaped sliding piece is slidably connected inside the contraction box. A plurality of springs are fixedly connected between the L-shaped sliding piece and the contraction box. A pressure-receiving block is fixedly connected to the lower part of the rear surface of the L-shaped sliding piece. The rear end of the pressure-receiving block penetrates to the rear of the contraction box and is in fit with the front surface of the wedge-shaped extrusion block located in front of the outer side wall of the turntable.

[0013] Furthermore, a cross arm is fixedly connected to the rear surface of the contraction box. A transfer cavity is fixedly connected to the upper surface of the cross arm. A discharge port is integrally formed on the lower surface of the transfer cavity and below the cross arm. A communication pipe is fixedly connected and communicated between the top of the transfer cavity and the bottom of the liquid discharge port.

[0014] Furthermore, a sealing block is fixedly connected to the rear end of the L-shaped sliding piece. The rear end of the sealing block penetrates into the interior of the transfer cavity and is slidably connected to the transfer cavity. A through-type docking hole is formed in the upper surface of the sealing block. The communication pipe and the discharge port are connected and communicated through the docking hole.

[0015] Furthermore, limiting grooves are symmetrically formed on the inner side of the collar. Limiting strips are fixedly connected to the outer side wall of the suction syringe and inside the limiting grooves.

[0016] Furthermore, a three-way regulating valve is integrally formed at the left end of the suction syringe. A puncture needle head is integrally formed at the left end of the three-way regulating valve. An external injection pipe is integrally formed at the top of the three-way regulating valve.

[0017] Beneficial effects: According to the angle required for puncture, control the electric push rod to contract. Then, under the connection of the second concave member and the connecting head, pull the rotating head to rotate along the inside of the first concave member to change the inclination degree of the suction syringe. Then, the pneumatic motor controls the screw to rotate. Under the limitation of the limiting groove and the limiting strip, the screw moves along the inside of the rotating head. Then, pull the suction syringe to slide along the inside of the collar, driving the puncture needle head to approach the human body to complete the puncture work.

[0018] After the puncture is completed, the puncture needle is connected to the suction syringe through the three-way regulating valve, and then the suction syringe is controlled to extract the sample to be obtained and discharge it through the discharge port;

[0019] After the extraction is completed, the three-way regulating valve can be adjusted to make the puncture needle and the external injection tube connected and connected. At this time, the corresponding drug can be injected through the external injection tube and injected into the human body through the puncture needle, avoiding the need for repeated insertion and removal in the prior art, and realizing the functions of extraction and injection;

[0020] Multiple placement ports can simultaneously hold multiple small-capacity sampling bottles. By rotating the turntable, multiple sampling bottles can be rotated to the bottom of the discharge port in turn, so that multiple sampling bottles can be connected to the multiple discharge ports in turn. After the sampling bottle is rotated to just below the discharge port, the wedge-shaped extrusion block will squeeze the pressure block. At this time, the L-shaped sliding piece is squeezed and moves forward, thereby driving the sealing block to move forward, so that the docking hole is connected with the connecting pipe and the discharge port. At this time, the extracted liquid can be discharged into the sampling bottle. During the rotation of the turntable, under the push of the spring, the L-shaped sliding piece moves to the rear of the shrinkage box. At this time, the sealing block shrinks into the transfer chamber. At this time, the docking hole is misaligned with the connecting pipe and the discharge port to avoid leakage of the sample liquid.

Detailed implementation manner

[0029] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 shown, a puncture sampling device for oncology is provided, including a bottom plate 1. A vertical rod 2 is fixedly connected to the upper surface of the bottom plate 1. The top end of the vertical rod 2 is fixedly connected to a first concave member 3. The inner side of the first concave member 3 is rotatably connected to a rotating head 4 through a rotating shaft. The top of the rotating head 4 is fixedly connected to a collar 5. The inner side of the collar 5 is slidably connected to an aspiration syringe 6;

[0032] A mounting seat 7 is fixedly connected to the right side of the outer wall of the aspiration syringe 6. A motor 8 is fixedly connected to the right side of the mounting seat 7. The left end of the output shaft of the motor 8 is fixedly connected to a screw 9 on the left side of the mounting seat 7. The left end of the screw 9 penetrates to the left side of the rotating head 4 and is threadedly connected to the rotating head 4;

[0033] An electric push rod 10 is fixedly connected to the left side of the vertical rod 2. The top end of the output end of the electric push rod 10 is fixedly connected to a connector 11. A second concave member 12 is fixedly connected to the left side of the rotating head 4 and outside the connector 11. Through-type connecting grooves 13 are formed in the front surface and the rear surface of the second concave member 12. Connecting columns 14 are fixedly connected to the front surface and the rear surface of the connector 11 inside the two connecting grooves 13;

[0034] A liquid discharge port 15 is integrally formed on the left side of the outer wall of the aspiration syringe 6;

[0035] Limiting grooves 30 are symmetrically formed in the inner side of the collar 5. Limiting strips 31 are fixedly connected to the outer wall of the aspiration syringe 6 inside the limiting grooves 30;

[0036] A three-way regulating valve 32 is integrally formed at the left end of the suction syringe 6. A puncture needle 33 is integrally formed at the left end of the three-way regulating valve 32. An external injection tube 34 is integrally formed at the top of the three-way regulating valve 32;

[0037] When the device is in use, the device is placed at the corresponding position through the bottom plate 1. According to the angle required for puncture, the electric push rod 10 is controlled to contract. Then, under the connection of the concave part two 12 and the connector 11, the rotating head 4 is pulled to rotate along the inside of the concave part one 3, changing the inclination degree of the suction syringe 6. Then, the pneumatic motor 8 controls the screw rod 9 to rotate. Under the limitation of the limiting groove 30 and the limiting strip 31, the screw rod 9 moves along the inside of the rotating head 4. Then, the suction syringe 6 is pulled to slide along the inside of the collar 5, driving the puncture needle 33 to approach the human body to complete the puncture work. After the puncture is completed, the three-way regulating valve 32 is used to control the puncture needle 33 to communicate with the suction syringe 6. Then, by controlling the suction of the suction syringe 6, the required sample is extracted and discharged through the drain port 15;

[0038] After the extraction is completed, the three-way regulating valve 32 can be adjusted to make the puncture needle 33 and the external injection tube 34 butt-connect and communicate. At this time, the corresponding drug can be injected through the external injection tube 34 and injected into the human body through the puncture needle 33, avoiding the need for repeated plugging and unplugging in the prior art and realizing the functions of extraction and injection.

[0039] As Figure 1 shown, an anti-slip pad 16 is fixedly connected to the lower surface of the bottom plate 1;

[0040] It has an anti-slip effect and ensures the stable placement of the device.

[0041] As Figure 2 、 Figure 4 and Figure 5 shown, a turntable 17 is rotatably connected to the upper surface of the bottom plate 1 and to the left of the vertical rod 2 through a rotating shaft. A plurality of placement openings 18 are formed on the upper surface of the turntable 17;

[0042] A plurality of wedge-shaped extrusion blocks 19 are integrally formed on the outer side wall of the turntable 17. The number of the plurality of wedge-shaped extrusion blocks 19 is the same as the number of the plurality of placement openings 18, and the positions correspond one by one;

[0043] A contraction box 20 is fixedly connected to the upper surface of the bottom plate 1 and in front of the turntable 17. An L-shaped sliding piece 21 is slidably connected inside the contraction box 20. A plurality of springs 22 are fixedly connected between the L-shaped sliding piece 21 and the contraction box 20. A pressure receiving block 23 is fixedly connected to the lower part of the rear surface of the L-shaped sliding piece 21. The rear end of the pressure receiving block 23 penetrates to the rear of the contraction box 20 and is in contact with the front surface of the wedge-shaped extrusion block 19 located in front of the outer side wall of the turntable 17;

[0044] A transverse arm 24 is fixedly connected to the rear surface of the shrink box 20. A transfer cavity 25 is fixedly connected to the upper surface of the transverse arm 24. A discharge port 26 is integrally formed below the lower surface of the transfer cavity 25 and below the transverse arm 24. A communicating pipe 27 is fixedly connected and communicated between the top of the transfer cavity 25 and the bottom of the liquid discharge port 15;

[0045] A sealing block 28 is fixedly connected to the rear end of the L-shaped sliding piece 21. The rear end of the sealing block 28 penetrates into the interior of the transfer cavity 25 and is slidably connected to the transfer cavity 25. A through docking hole 29 is formed in the upper surface of the sealing block 28. The communicating pipe 27 and the discharge port 26 are connected and communicated through the docking hole 29;

[0046] Multiple placement ports 18 can simultaneously place multiple small-capacity sampling bottles. By rotating the turntable 17, the multiple sampling bottles can be sequentially rotated below the discharge port 26, so that the multiple sampling bottles can be sequentially communicated with the multiple discharge ports 26. After the sampling bottle rotates directly below the discharge port 26, the wedge-shaped pressing block 19 will press the pressed block 23. At this time, the L-shaped sliding piece 21 is pushed forward, and then drives the sealing block 28 to move forward, so that the docking hole 29 is communicated with the communicating pipe 27 and the discharge port 26. At this time, the extracted liquid can be discharged into the sampling bottle. During the rotation of the turntable 17, under the push of the spring 22, the L-shaped sliding piece 21 moves to the rear of the interior of the shrink box 20. At this time, the sealing block 28 shrinks into the transfer cavity 25. At this time, the docking hole 29 is misaligned with the communicating pipe 27 and the discharge port 26, avoiding the problem of leakage of the sample liquid.

[0047] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
