Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following provides preferred embodiments with reference to the attached drawings to further elaborate on the present invention in detail. However, it should be noted that many details listed in the description are only for enabling the reader to have a thorough understanding of one or more aspects of the invention, and these aspects of the present invention can be implemented even without these specific details.

[0026] Please refer to Figures 1 to 7 , the present invention provides a pathological sampling device for lung cancer patients in oncology, and the technical solution is as follows:

[0027] It includes a connecting frame 1, a sampling cylinder 2 is provided on the connecting frame 1, and a needle 3 is provided at the lower end of the sampling cylinder 2. A partition plate 4 is provided in the sampling cylinder 2, and the partition plate 4 divides the sampling cylinder 2 into an upper cavity 401 and a lower cavity 402. A connecting block 5 is provided on the outer side wall of the connecting frame 1, and a bracket 6 is provided at the other end of the connecting block 5. An electric telescopic rod 7 and a guide rod 8 are respectively provided at both ends of the bracket 6, and both the electric telescopic rod 7 and the guide rod 8 are arranged on the bed frame. A sliding groove 9 is opened on the side of the connecting frame 1 away from the connecting block 5. An operating rod 10 is provided in the sliding groove 9, and the other end of the operating rod 10 is connected to the sampling cylinder 2. A sampling tube 11 is provided at the lower edge of the sampling cylinder 2, and a solenoid valve is provided on the sampling tube 11. A connecting tube 12 is provided at the top of the sampling cylinder 2, and the connecting tube 12 is communicated with the inside of the sampling cylinder 2. A suction tube 13 is connected to the connecting tube 12, and a suction assembly is provided at the other end of the suction tube 13.

[0028] The patient lies on the hospital bed and the position is initially adjusted. The part to be sampled is moved under the needle 3. The electric telescopic rods 7 and the guide rods 8 at both ends of the bracket 6 are arranged on the bed frame, which can conveniently adjust the position of the sampling device and keep it stable, realizing accurate positioning and fixation, avoiding the random movement of the extraction tool during the liquid extraction process, and reducing the harm to the patient. After adjusting the puncture position, the medical staff operates the electric telescopic rod 7 to contract, driving the needle 3 to gradually approach the patient until it hovers 2-3 cm away from the patient. Then, the sampling cylinder 2 is driven to perform puncture sampling through the operating rod 10. At the same time, the suction assembly is operated, and the pressure in the upper cavity 401 is increased through the suction pipe 13 and the connecting pipe 12. The upper pressure is greater than the sum of the lower pressure and the resistance such as the friction force and gravity of the sealing plate. According to the principle of force balance, the sealing plate will receive an upward resultant force and thus move upward. The upward movement of the sealing plate will increase the volume of the lower cavity 402. According to Boyle's law, the volume of the gas in the lower cavity 402 increases and the pressure decreases. When it is less than the external atmospheric pressure, under the action of the pressure difference, the effusion will be sucked into the lower cavity 402 through the lower needle 3. The medical staff then receives the effusion from the sampling pipe 11, and at this time, a sampling of pleural effusion is completed.

[0029] The suction assembly includes a suction box 14. A suction cylinder 15 is provided in the suction box 14. The connecting pipe 12 is connected to the top of the suction box 14, and the connecting pipe 12 passes through the suction box 14 and is communicated with the suction cylinder 15. A suction plate 16 is provided in the suction cylinder 15, and a suction rod 17 is provided at the lower end of the suction plate 16. A driving plate 18 is provided at the lower end of the suction pipe 13, and the diameter of the driving plate 18 is larger than the diameter of the suction cylinder 15. A driving mechanism is provided on the suction box 14. The driving mechanism includes a through groove 19 opened on the side of the suction box 14. A support ring 20 is provided at the upper end of the driving plate 18, and an L-shaped rod 21 is provided at the top of the support ring 20. The L-shaped rod 21 extends outward through the through groove 19, and a pedal 22 is provided on the L-shaped rod 21. The pedal 22 is inclined.

[0030] By providing the pedal 22 on the L-shaped rod 21, the medical staff can control the suction action by stepping on the pedal 22, liberating both hands, and being able to more conveniently assist in fixing the sampling part and other operations during the sampling process, improving the operation convenience and fluency. The pedal 22 is inclined, which conforms to ergonomics, is more convenient for the foot to apply force and control the stepping amplitude, making the operation process more comfortable and labor-saving. The diameter of the driving plate 18 is larger than the diameter of the suction cylinder 15. Cooperating with the support ring 20, it can prevent components such as the suction rod 17 from coming out of the suction cylinder 15, ensuring the structural stability of the suction assembly. Through the cooperation of the suction plate 16, the suction rod 17 and the driving plate 18, stepping on the pedal 22 drives the L-shaped rod 21, the driving plate 18 and the suction rod 17 to move, so that the suction plate 16 effectively changes the internal space volume in the suction cylinder 15, realizing efficient liquid suction and meeting the sampling requirements.

[0031] Refer toFigure 7 The driving mechanism includes a through groove 19 formed on the side of the suction box 14. A support ring 20 is provided at the upper end of the driving plate, and an L-shaped rod 21 is provided at the top of the support ring 20. The L-shaped rod 21 extends outwards through the through groove 19. A support plate 31 is provided on the L-shaped rod 21. An installation seat 32 is provided on the side of the suction box, and a driving cylinder 33 is provided on the installation seat 32. The output end of the driving cylinder 33 is connected to the support plate 31.

[0032] Medical staff can operate the driving cylinder 33 through the control system outside the CT room without frequently entering and leaving the scanning room to open the protective door; by arranging the driving cylinder 33 on the L-shaped rod 21, medical staff can control the suction action through remote control;

[0033] Compared with the operation of the pedal 22, remote control allows medical staff to operate in a safe area outside the CT room without frequently entering and leaving the scanning room; this greatly reduces the time and frequency of medical staff being exposed to the radiation environment, effectively reduces the risk of long-term occupational radiation exposure, and provides a solid guarantee for the health of medical staff;

[0034] For the operation of the pedal 22, by directly applying force with the foot, medical staff can real-time sense information such as the stepping force and displacement feedback. With rich clinical experience and sensitive touch, they can finely and timely adjust the suction force and speed to ensure the smoothness and fluency of the sampling process and improve the sampling success rate; medical staff can choose according to the operation requirements.

[0035] An annular groove 23 is formed at the top of the connecting pipe 12, and a first permanent magnet ring 24 is provided in the annular groove 23. A second permanent magnet ring 25 is provided at one end of the suction pipe 13 close to the connecting pipe 12, and the first permanent magnet ring 24 and the second permanent magnet ring 25 cooperate with each other. Threads are provided at the connection between the connecting pipe 12 and the suction pipe 13, and the connecting pipe 12 and the suction pipe 13 are connected through a threaded sleeve 26.

[0036] The first permanent magnet ring 24 and the second permanent magnet ring 25 cooperate with each other, and can be automatically adsorbed and aligned by magnetic force when the connecting pipe 12 and the suction pipe 13 approach, which is convenient for quick positioning, reduces the connection difficulty, and decreases the overall operation difficulty; on the basis of the preliminary magnetic positioning, threaded connection is carried out through the threaded sleeve 26 to further tighten and reinforce, so that the connecting pipe 12 and the suction pipe 13 are tightly and firmly connected, preventing separation due to pulling, vibration, etc. during the sampling process and ensuring stable liquid transmission; at the same time, when the device needs to be cleaned, repaired or components need to be replaced, by unscrewing the threaded sleeve 26, the connecting pipe 12 and the suction pipe 13 can be easily separated, with simple operation, which is convenient for daily maintenance and component replacement, and improves the service life and use efficiency of the device.

[0037] The connecting block 5 is provided with a slot 27, and a wedge-shaped insert block 28 is arranged on one side of the connecting frame 1 close to the connecting block 5, and the wedge-shaped insert block 28 is matched with the slot 27; the cooperation between the wedge-shaped insert block 28 and the slot 27 can quickly realize the positioning and preliminary docking of the connecting frame 1 and the connecting block 5. During installation, only need to align the wedge-shaped insert block 28 with the slot 27 and insert it, without complex debugging and alignment operations, greatly improving the assembly efficiency of the device and saving installation time; the wedge-shaped structure of the wedge-shaped insert block 28 enables it to fit tightly with the slot 27 after being inserted into the slot 27, which can effectively prevent relative shaking or displacement between the connecting frame 1 and the connecting block 5 during use, ensuring the stability of the entire device structure, and further ensuring the accuracy of the sampling operation.

[0038] A laser display 29 is arranged at the bottom of the connecting frame 1, and the laser display 29 is close to the needle 3 and in the same vertical plane as the needle 3; the laser display 29 and the needle 3 are in the same vertical plane. During sampling, the vertical projection position of the needle 3 can be accurately indicated by the laser beam; medical staff can more intuitively and accurately determine the puncture and needle insertion point on the patient's body surface based on the laser projection point, improving the accuracy of the sampling site and reducing the situation of multiple punctures or sampling failures caused by positioning deviation; compared with relying solely on experience or traditional measurement and positioning methods, the laser display 29 can quickly help medical staff find the needle insertion position, shorten the positioning time, thereby improving the efficiency of the entire sampling operation and reducing the waiting time of patients.

[0039] A plurality of reset springs 30 are arranged circumferentially on the suction plate 16, and the other ends of the plurality of reset springs 30 are all connected to the inner top wall of the suction box 14; when the foot pedal 22 drives the suction rod 17 to drive the suction plate 16 to move downward to complete suction, when the pedal 22 is released, the elastic force of the reset spring 30 will automatically pull the suction plate 16 back to the initial position, avoiding the cumbersome operation of manual reset by medical staff, saving manpower and improving the sampling efficiency; at the same time, ensuring that the suction plate 16 can accurately return to its original position after each suction action, facilitating repeated operations;

[0040] The reset spring 30 is in a stretched state during the suction process (when the suction plate 16 moves downward), and provides a stable reverse resistance through the elastic force, making the movement process of the suction plate 16 smoother, avoiding uneven suction speed caused by sudden changes in external forces; ensuring that the liquid volume sucked each time is consistent, improving the sampling accuracy, especially suitable for detection scenarios with strict requirements for the sample volume.

[0041] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
