Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a clinical biopsy sample sampling device for oncology, which has the advantages of being able to effectively cut multiple tumor samples, and solves the problem that most tumor biopsy sample sampling devices use a sampling needle to rotate for scraping and sampling , so that the sampling effect and the amount of sampled samples are unstable, which will lead to the problem that multiple sampling increases the pain of patients

Embodiment 1

[0032] see Figure 1-6 , the present invention provides a technical solution: a clinical biopsy sample sampling device for oncology department, comprising a round tube 1, a joystick 2 is movably connected in the round pipe 1, a sampling needle 9 is arranged on the joystick 2, and the lower end of the round pipe 1 The puncture needle 5 is fixedly connected, and the sampling needle 9 is movably connected with the puncture needle 5. The upper end of the sampling needle 9 is provided with a chute 26, and a moving rod 14 is movably connected in the chute 26, and a connecting column 7 is fixedly installed on the upper end of the moving rod 14. The upper end of the column 7 is connected with a connecting rod 6, the connecting rod 6 is fixedly connected with the control rod 2, and the outer wall of the sampling needle 9 is provided with three annular wall grooves 15, and the sampling needle 9 is movably connected with three lifting rings 17, and the inner wall of the chute 26 There ar...

Embodiment 2

[0037] On the basis of Example 1, please refer to Figure 1-6 , the lower end of the screw 12 is fixedly connected with two lifting rods 10, the upper end of the connecting column 7 is provided with a circular groove 11, the screw rod 12 is movably connected with the circular groove 11, the two lifting rods 10 move through the lower inner wall of the circular groove 11, and the two lifting rods The lower end of 10 is fixedly installed with circular plate 21, and circular plate 21 is movably socketed on the moving rod 14, and pressure spring 20 is movably socketed on the moving rod 14, and the upper end of pressure spring 20 is fixedly connected with connecting column 7, and the pressure spring 20 The lower end is fixedly connected with the circular plate 21. By aligning the screw rod 12 with the threaded groove 13 and then rotating the connection, the screw rod 12 can be driven to move upward, thereby driving the two elevating rods 10 to move upward, so that the circular plate ...

Abstract

The invention relates to the technical field of medical instruments, and discloses an oncology clinical biopsy sample sampling device. The oncology clinical biopsy sample sampling device comprises a round tube, a control rod is movably connected in the round tube, a sampling needle is arranged on the control rod, a puncture needle is fixedly connected to the lower end of the round tube, the sampling needle is movably connected with the puncture needle, a moving rod can be driven to move downwards by pressing the control rod downwards, three connecting strips can be driven to move downwards, and therefore, lifting rings can be correspondingly driven to move downwards; after the three connecting strips are correspondingly in contact with the lower inner walls of the three connecting grooves, the sampling needle can be driven to move downwards to be inserted into a tumor, then the control rod is moved upwards, the moving rod can be driven to move upwards, and the three lifting rings can be correspondingly driven by the three connecting strips to move upwards to cut the tumor entering an annular wall groove; and then the sampling needle can be driven to move upwards to take out a sample when the three connecting strips make contact with the inner walls of three connecting grooves, and a plurality of tumor samples can be effectively cut.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clinical biopsy sample sampling device for oncology departments. Background technique [0002] Existing publication number CN109431553A discloses a clinical biopsy sample sampling device in the oncology department, comprising an outer box, a puncture needle, a sampling tube and a push rod, the puncture needle is inserted in the outer box, and the sampling tube is composed of two semi-circular The sampling needle is fastened and inserted into the left end of the puncture needle. The left and right ends of one sampling needle are respectively fixed with the first cutting line and the second cutting line. An L-shaped rod is fixedly connected with a rack meshing with the upper gear of the puncture needle. The push rod is inserted into the puncture needle, and a push block is fixedly connected to the left end of the push rod. The structure design of the present invention is...
