Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a tumor sampling device for pathological diagnosis of tumor patients. Background Technology

[0002] During cancer treatment, medical staff often perform tumor cell biopsies to better understand the characteristics of the tumor, thus facilitating targeted treatment. Currently, tumor sampling is typically performed using a sampling needle. Existing patent publication number CN221308257U discloses a lung tumor sampling device, including a cannula. Finger rings are fixedly installed on both sides of the cannula. A connector is centrally located at the front end of the cannula, and an outer needle tube is centrally fixedly installed on the front of the connector. The outer circumference of the outer needle tube has several graduation lines. A sampling groove is formed at the front of the top of the outer needle tube, and a puncture head is located at the front end of the outer needle tube. A piston is located inside the cannula. The piston rod has an inner needle fixedly installed at the center of its front end, and a cutter is fixedly installed at the front end of the inner needle. The connector is threaded to the sleeve. In this scheme, the pain caused to the patient by repeated sampling by the sampling needle is reduced by setting an outer needle tube. However, after the outer needle tube is placed in the human body, it is supported and limited by human tissue. When medical staff pull the sampling needle (or move the sampling needle for multiple samplings), the outer needle tube is easy to shake and cause secondary damage to the puncture site. In addition, there is a risk that the outer needle tube will move and fall off, which is not conducive to the biopsy sampling of tumor cells. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a tumor sampling device for pathological diagnosis of tumor patients, including a positioning component and a sampling tube 1 with open ends. A detachable guide tube 5 is installed at the bottom of the sampling tube 1. By disassembling the guide tube 5, it is convenient to replace the guide tube 5 of different lengths according to the needs of use, and at the same time, it is convenient to replace and clean the guide tube 5.

[0020] A movable plate 6 is slidably disposed inside the sampling tube 1, and an installation plate 7 is fixed to the bottom of the movable plate 6. A sampling needle 8 is fixed to the side of the installation plate 7. The sampling needle 8 is hollow and is slidably disposed inside the guide tube 5. Medical staff can drive the installation plate 7 to move by pushing the movable plate 6, so as to control the movement of the sampling needle 8 on the side of the installation plate 7 inside the guide tube 5.

[0021] The sampling needle 8 has a sampling hole 9 on its lower side. During the puncture, the sampling needle 8 is located inside the guide tube 5, which protects the sampling needle 8 and prevents human tissue from entering the sampling needle 8 through the sampling hole 9, ensuring that the sampling needle 8 can effectively sample tumor cells. With the assistance of medical imaging, when the guide tube 5 is punctured to the tumor location, medical staff can push the sampling needle 8 out of the guide tube 5 to sample tumor cells. The design of the guide tube 5 facilitates multiple sampling of tumor cells through the sampling needle 8, which is convenient for tumor cell biopsy. After sampling the tumor cells, the sampling needle 8 moves into the guide tube 5, which protects the sampling needle 8 and prevents the sampled tumor cells from falling out of the sampling needle 8.

[0022] Preferably, the bottom of the sampling needle 8 is needle-shaped, and the bottom of the sampling tube 1 is cone-shaped. During the puncture process, the bottom of the sampling needle 8 is located outside the bottom end of the guide tube 5. The needle-shaped structure at the bottom of the sampling needle 8 punctures the human tissue, and then the cone-shaped structure at the bottom of the sampling tube 1 opens up the human tissue, making it easier for the sampling device to puncture the human body.

[0023] The positioning component is used to position and guide the guide tube 5 during puncture. The positioning component includes a positioning plate 12, a positioning cylinder 13 fixed to the side of the positioning plate 12, and a through hole communicating with the inner cavity of the positioning cylinder 13 on the side of the positioning plate 12. The outer side of the guide tube 5 contacts the inner side of the positioning cylinder 13. Straps 16 are fixed on both sides of the positioning plate 12. During puncture and sampling, the positioning plate 12 is fixed at the patient's puncture position by the straps 16. Then, the guide tube 5 is placed in the positioning cylinder 13. The positioning cylinder 13 positions and guides the guide tube 5, which facilitates vertical needle insertion. When the sampling needle 8 moves in the guide tube 5, the positioning cylinder 13 improves the stability of the guide tube 5 and avoids the guide tube 5 shaking and causing secondary damage to the puncture position. At the same time, the positioning cylinder 13 prevents the guide tube 5 from moving or even falling off, ensuring the effective use of the guide tube 5.

[0024] A conical cylinder 14 is fixed to the top of the positioning cylinder 13, and the diameter of the conical cylinder 14 gradually decreases from top to bottom. The positioning cylinder 13 is in contact with the inner cavity of the conical cylinder 14. The setting of the conical cylinder 14 makes the top of the positioning cylinder 13 open, which makes it easy to place the guide tube 5 inside the positioning cylinder 13.

[0025] Several reinforcing plates 15 are fixed to the side of the positioning plate 12, and the reinforcing plates 15 are fixedly connected to the side of the positioning cylinder 13. The reinforcing plates 15 improve the connection strength between the positioning plate 12 and the positioning cylinder 13. A protective pad 17 is provided on the lower part of the side of the positioning plate 12, and an opening is provided on the side of the protective pad 17 corresponding to the position of the through hole. The protective pad 17 includes, but is not limited to, cotton pads, non-woven fabrics, etc. The protective pad 17 is used to buffer the pressure of the positioning plate 12 on the human body. At the same time, the protective pad 17 improves the fit strength between the positioning plate 12 and the human body, and plays a role in sterilization and hemostasis.

[0026] The bottom of the sampling tube 1 is fixed with a connecting tube 2 that communicates with its inner cavity. The top of the guide tube 5 is fixed with a rotating plate 3. A connecting post 4 is fixed on the upper side of the rotating plate 3. The connecting post 4 is snapped into the connecting tube 2. The rotating plate 3 is designed to facilitate the removal of the connecting post 4 from the connecting tube 2 and the disassembly of the guide tube 5. Preferably, the connecting post 4 and the connecting tube 2 are fixed by a threaded connection. The rotating plate 3 and the connecting post 4 are both provided with round holes at the positions corresponding to the through holes on their sides to ensure that the sampling needle 8 is effectively placed in the guide tube 5 for use.

[0027] The top of the movable plate 6 is fixed with a first ear plate 10, and the top of the sampling tube 1 is fixed with a second ear plate 11. The first ear plate 10 and the second ear plate 11 facilitate medical staff to push the sampling needle 8 to move and collect samples.

[0028] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
