Problems solved by technology

[0003] At present, when performing bronchial biopsy, many tools are needed, such as puncture needles, biopsy forceps, electric snares, etc. These instruments are all slender structures because they need to be introduced into the branch tube, and they need to be inserted into the tube. Disinfection treatment, but due to the long and slender structure, part of the uninserted part

Embodiment 1

[0026] see Figure 1-Figure 3 , a device for transbronchial needle aspiration biopsy under ultrasonic bronchoscope in the figure includes a fixing frame 1, the outer end of the fixing frame 1 is fixed with a butt tube 2, and the outer side of the fixing frame 1 is fixed with a support frame 3, It also includes a push assembly 4 installed on the support frame 3, a rotating pipe 6 that is rotatably inserted into the outer end of the butt pipe 2, and two butt plates 8 fixed at the bottom of the butt pipe 2. The butt pipe 2 A bracket is fixed on the outside, and a linkage 5 is installed in the bracket, and a wetting mechanism 7 is installed on the rotating pipe 6 and the butt pipe 2, and a docking rod 9 is fixed on the outside of the two docking plates 8, The outer side of the docking rod 9 is provided with a fitting member 10 which is opposite to the rotating tube 6 .

[0027] It should be noted that: in this solution, the traditional biopsy instrument is optimized, and a wettin...

Embodiment 2

[0041] see Figure 5 and Image 6 , this embodiment further describes Example 1. The fitting 10 in the figure includes a fitting tube 30, and a butt ring 31 is rotatably installed at the outer end of the fitting tube 30, and the butt ring 31 and the rotating A connecting ring 32 is rotatably installed between the tubes 6, and a plurality of sticking rods 33 are fixed equiangularly on the outside of the connecting ring 32. The bottom ends of the sticking rods 33 are all fixed with brushes, and the inner side of the rotating pipe 6, etc. The angle is fixed with a plurality of adjustment blocks 34;

[0042] It is worth noting that the designed fitting tube 30 can be disassembled and replaced with tubes of different inner diameters, so as to satisfy the fitting treatment of long biopsy tubes of different diameters, making the use and operation more flexible.

[0043] It should be noted that the fitting rod 33 on the outer side of the connecting ring 32 satisfies the wiping of th...

Embodiment 3

[0045] see Figure 5 , this embodiment further describes other embodiments, the outer end of the docking rod 9 in the figure is fixed with a limit ring 35, and the outer side of the fitting tube 30 is fixed with a connecting plate 36 that is inserted into the docking rod 9 , the outer ends of the docking rods 9 are all screwed with abutting caps 37, and at the same time, in order to facilitate the observation of the long biopsy tube and the pushing movement of the long biopsy tube, the fitting tube 30 is made of transparent rubber material;

[0046] It is worth noting that: when the fitting tube 30 is replaced, the designed abutting cap 37 and the limiting ring 35 cooperate with each other, so that the connecting plate 36 can perform a limiting effect, so that the fitting tube 30 can be disassembled. Installation is more convenient.

Abstract

The invention discloses a transbronchial needle aspiration biopsy operation instrument under an ultrasonic bronchoscope, relates to the technical field of biopsy instruments, and solves the problem that the outer wall of an existing biopsy long tube is dry and difficult to insert, the transbronchial needle aspiration biopsy operation instrument comprises a fixing frame, a butt joint tube is fixed to the outer end of the fixing frame, and a supporting frame is fixed to the outer side of the fixing frame; the pushing assembly is installed on the supporting frame, the rotating pipe is rotationally connected to the outer end of the butt-joint pipe in an inserted mode, the two butt-joint plates are fixed to the bottom of the butt-joint pipe, a support is fixed to the outer side of the butt-joint pipe, a linkage piece is installed in the support, wetting mechanisms are installed on the rotating pipe and the butt-joint pipe, and butt-joint rods are fixed to the outer sides of the two butt-joint plates. According to the biopsy instrument, the wetting mechanism is additionally arranged on a common biopsy instrument, so that the outer wall of the long-tube instrument can be wetted before the biopsy instrument is inserted into a branch tube of the throat of a patient, abrasion caused by the fact that the dry outer wall is inserted into the throat is reduced, and the patient is more comfortable in an operation.

Description

technical field [0001] The invention relates to the technical field of biopsy instruments, in particular to a transbronchial needle aspiration biopsy instrument under ultrasonic bronchoscope. Background technique [0002] Bronchoscopy biopsy is an important part of bronchoscopy. Bronchoscopy means that the bronchoscope enters the trachea, bronchi and their branches, and after finding diseased tissue or suspicious diseased tissue, bronchoscopy biopsy takes the diseased tissue. The tissue removed is usually done for pathological examination. [0003] At present, many tools are needed when performing bronchial biopsy, such as puncture needles, biopsy forceps, electric snare, etc. Since these devices need to be introduced into branch tubes, they are all slender structures. Disinfection treatment, but due to the long slender structure, part of the uninserted part is exposed to the air, the outer wall will become dry, and when the part that remains outside is inserted, due to the...
