Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] see Figure 1-9 , the present invention provides a tumor puncture extraction device, comprising a needle 1 and a needle tube 2 for extracting liquid, the needle tube 2 communicates with the needle 1, the needle 1 is screwed to the suction pipe 201, and the top of the needle 1 is fixedly connected with a layered sampling device 4. The bottom of the stratified sampling device 4 is connected with a liquid guiding device 302 , the bottom of the stratified sampling device 4 is movably socketed with the liquid guiding device 302 through a ring 301 , and the bottom of the liquid guiding device 302 is connected with a negative pressure pipeline 303 .

[0031] Specifically, the distance sensor provided at the bottom of the needle 1 can know the distance between the needle 1 and the skin surface after the needle 2 pierces the skin surface. The unit can co...

Abstract

The invention provides a tumor puncture extraction device, and relates to the field of medical treatment. The tumor puncture extraction device comprises a needle and a needle tubing used for extracting liquid, the needle tubing is in communication with the needle, the needle is in threaded connection with an extraction pipeline, the top end of the needle is fixedly connected with a stratified sampling device, the bottom of the stratified sampling device is in communication with a liquid guide device, the bottom of the stratified sampling device is movably sleeved with the liquid guide device through a circular ring, and the bottom end of the liquid guide device is in communication with a negative pressure pipeline. According to the tumor puncture extraction device, a fan-shaped rotating cavity in a rotating connecting device can be driven to rotate through rotation of a servo motor, a connecting nozzle communicating with the outer surface of the fan-shaped rotating cavity can communicate with a connecting hole formed in the inner wall of a cylindrical cavity, and tumor tissues of different depths can be extracted and conveyed conveniently.

Description

technical field [0001] The invention relates to the medical field, in particular to a tumor puncture extraction device. Background technique [0002] Tumor biopsy is a very important means of diagnosing benign and malignant tumors. Tumor needle biopsy is usually performed under the guidance of CT or ultrasound. After the location of the tumor is determined, a biopsy needle is used to puncture into the tumor tissue to take out an appropriate tumor tissue, which is sent for pathological examination to determine whether it is a benign tumor or a malignant tumor. Give further treatment. [0003] Existing tumor puncture extraction devices generally detect the tumor site through puncture and suction of tissue cells, which cannot carry out detailed classification and sampling of the diffuse tumor cells. In order to extract and detect the tumor part more comprehensively, this program adopts multiple Level tumor puncture extraction device to solve the above problems. Contents of ...
