Description

Technical Field

[0001] The utility model relates to the technical field of tumors, in particular to a tumor biopsy sampling device. Background Art

[0002] Tumor biopsy is an important means of tumor detection. Compared with traditional imaging information, directly obtaining tumor cells for testing can achieve the most accurate status estimation and determine the type and stage of the tumor. The difficulty of tumor biopsy lies in how to achieve quantitative acquisition. It is difficult to control the depth of the tumor. At the same time, obtaining tumor biopsy samples is also relatively difficult, and a cutting-type acquisition method is required.

[0003] To this end, we propose a tumor biopsy sampling device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a tumor biopsy sampling device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A tumor biopsy sampling device includes a handle, a puncture needle, a knob, and a needle. The puncture needle is in the shape of a hollow tube and is fixed to the lower end of the handle. The knob is inserted into the end of the handle. The lower end of the knob is fixedly connected to a connecting needle. The connecting needle passes through the handle and is inserted into the inside of the puncture needle. The lower end of the connecting needle is fixedly connected to the needle head, and the needle head passes through the port of the puncture needle. An elastic slice is provided inside the puncture needle.

[0007] Preferably, the knob and the handle are fixed to each other via a threaded connection.

[0008] Preferably, an operating plate is fixedly connected to the side end of the knob, and the operating plate is L-shaped.

[0009] Preferably, the needle tip protrudes 0.5-1 cm from the port of the puncture needle.

[0010] Preferably, the elastic slices are provided in a plurality of pieces and are arranged in a ring-shaped layout at the edge of the port of the puncture needle.

[0011] Preferably, the elastic slice is arc-shaped, one end of the elastic slice is fixedly connected to the inner wall of the puncture needle, and one end of the elastic slice is raised and sharp.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Through the coordination of the puncture needle, needle head and connecting needle, the sample can be directly obtained by puncturing with the puncture needle. During the puncture process, the depth can be controlled to achieve a better quantitative position effect. At the same time, the needle head and connecting needle can be used to control the sample acquisition at the tip, achieving the purpose of simplicity, speed and efficiency.

[0014] 2. By cooperating with the elastic slice and the operation panel, the operation panel can be used to more conveniently control the knob, so that the elastic slice can be unfolded by the control knob to cut and separate the sample at the end, thereby eliminating the traditional complex structure.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Compared with traditional imaging information, directly obtaining tumor cells for testing can achieve the most accurate status estimation. However, it is difficult to control the depth of the tumor. It is also difficult to obtain tumor biopsy samples, which requires a cutting type of acquisition method. Figure 1-3 This scheme designs a tumor biopsy sampling device, including a handle 1, a puncture needle 2, a knob 3, and a needle 4. The puncture needle 2 is made of medical stainless steel, and the length of the puncture needle 2 is maintained between 1500mm and 1000mm (rod length). The handle 1 is an overall cylindrical shape.

[0021] Specifically: the puncture needle 2 is in the shape of a hollow tube, and the puncture needle 2 is fixed to the lower end of the handle 1. The handle 1 is used for hand-held operation. The knob 3 is inserted at the end of the handle 1. The knob 3 is turned to perform corresponding control of both hands. The knob 3 and the handle 1 are fixed to each other through a threaded connection. The threaded connection ensures that the knob 3 can rotate stably and automatically lock. A connecting needle 5 is fixedly connected to the lower end of the knob 3, and an operating panel 7 is fixedly connected to the side end of the knob 3. The operating panel 7 is L-shaped. The purpose of the operating panel 7 is to increase the contact area between the finger and it, and to drive the knob 3 through surface contact, which is easier and more efficient.

[0022] Specifically: the connecting needle 5 passes through the handle 1 and is inserted into the inside of the puncture needle 2. The lower end of the connecting needle 5 is fixedly connected to the needle head 4. The needle head 4 passes through the port of the puncture needle 2, and the needle head 4 is exposed 0.5-1 cm from the port of the puncture needle 2. An elastic slice 6 is provided in the puncture needle 2. Therefore, after puncturing to the predetermined position (the operation is guided under the imaging environment), the connecting needle 5 is lifted by turning the knob 3. The connecting needle 5 drives the needle head 4 to retract into the inside of the puncture needle 2, so that negative pressure is generated during the entry process, thereby sucking some tumor cells and sucking them into the inside of the puncture needle 2 to achieve quantitative acquisition, and then the elastic slice 6 is used to cut and separate them.

[0023] Specifically: the elastic slice 6 is provided with multiple pieces, which are arranged in a ring layout at the edge of the port of the puncture needle 2. The elastic slice 6 is arc-shaped, and one end of the elastic slice 6 is fixedly connected to the inner wall of the puncture needle 2. One end of the elastic slice 6 is raised and sharp. The elastic slice 6 has the characteristic of self-bending. Under normal conditions, it is squeezed by the needle 4 and shrinks on the inner wall of the puncture needle 2. After the needle 4 leaves the specific position, the elastic slice 6 is released and expanded, and the sheet structure of its own end is used to cut the tumor cells, thereby achieving the separation effect.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
