Embodiment 1

[0041] see figure 1 , 7 and 8, a needle-guiding device for biopsy needles for pleural diseases, used to guide the biopsy needle 14, comprising a support frame 1 and a connecting frame 8 slidably installed on the support frame 1, the connecting frame 8 is installed by The driving mechanism on the support frame 1 is driven to move vertically;

[0042] A receiving member 10 is fixed on the connecting frame 8 along the horizontal direction, and a clamping mechanism for fixing the biopsy needle 14 is fixedly installed on the receiving member 10;

[0043]A cutting assembly is arranged at the vertical position of the biopsy needle 14, the cutting assembly is mounted on a mounting frame connected to the receiving member 10 through an elastic assembly, and the mounting frame is provided with a device for driving the cutting assembly. A moving telescopic assembly, the telescopic assembly is controlled by the trigger mechanism installed on the support frame 1. When the mounting frame m...

Embodiment 2

[0048] see figure 1 , the drive mechanism includes a threaded rod 5 rotatably mounted on the support frame 1 and a threaded sleeve 6 threaded on the threaded rod 5 and fixedly connected with the connecting frame 8, the threaded rod 5 One end is also fixedly connected with the output shaft of the motor 7 installed on the support frame 1 .

[0049] The provided motor 7 drives the threaded rod 5 to rotate when the threaded rod 5 rotates. When the threaded rod 5 rotates, it cooperates with the sliding action of the connecting frame 8 and the support frame 1 to realize the axial movement of the threaded sleeve 6 along the threaded rod 5. When the threaded sleeve 6 moves To drive the connecting frame 8 and the overall movement connected with the connecting frame 8, so as to realize the driving requirement.

[0050] Among them, it should be noted that the motor 7 is a forward and reverse motor, using a 4IK / 80YYJT type motor, which has stable performance, and other types of motors ca...

Embodiment 3

[0052] see Figure 6 , the driving mechanism includes a third electric telescopic rod 34 installed on the support frame 1 , and the movable end of the third electric telescopic rod 34 is fixedly connected with the connecting frame 8 .

[0053] In the embodiment of the present invention, the application adopts the telescopic effect of the third electric telescopic rod 34 to realize the vertical drive of the connecting frame 8, which is the same as the driving effect of the motor 7 in the above-mentioned embodiment, only the structure is different, so the present application This will not be repeated here.

Abstract

The invention is applicable to the technical field related to medical instruments, and provides a guide needle insertion device for pleural disease biopsy needles; the guide needle insertion device comprises a support frame and a connecting frame slidably mounted on the support frame, and the connecting frame is driven by a driving mechanism mounted on the support frame to vertically move; a bearing piece is fixed to the connecting frame in the horizontal direction, and a clamping mechanism used for fixing the biopsy needle is fixedly installed on the bearing piece. A cutting assembly is arranged at the vertical position of the biopsy needle and installed on an installation frame connected with the bearing piece through an elastic assembly, a telescopic assembly used for driving the cutting assembly to move is arranged on the installation frame, and the telescopic assembly is controlled by a trigger mechanism installed on the supporting frame to move. The biopsy needle can be automatically guided, meanwhile, the skin at the puncture position can be automatically cut through the cutting assembly, and medical workers do not need to manually cut the skin.

Description

technical field [0001] The invention belongs to the related technical field of medical devices, and in particular relates to a device for guiding needle insertion of a pleural disease biopsy needle and a use method thereof. Background technique [0002] Biopsy needle is a kind of biopsy needle used for sampling and absorbing cells of pyramidal tumors and unknown tumors in various organs such as kidney, liver, lung, breast, thyroid, prostate, pancreas, testis, uterus, ovary, and body surface. of medical devices. [0003] Acupuncture pleural biopsy is a simple and safe method for diagnosing pleural diseases. Abrams pleural biopsy needles are commonly used. During surgery for pleural diseases, a 3 mm long skin vertical incision is made at the puncture site, and the puncture biopsy The needle was inserted into the pleural cavity, the needle core was removed, and a syringe was attached to collect pleural effusion samples. Then turn the inner cannula to reveal the slot of the ou...
