Description

Technical Field

[0001] The present invention relates to the field of tumor sampling, and in particular to a device for sampling lung cancer tumors and a method of using the same. Background Art

[0002] Lung tumors are divided into benign tumors and malignant tumors (see lung cancer). Benign lung tumors include true tumors of the bronchus and lung, adenomas, leiomyomas, lipomas, fibromas, etc., which are a very rare group of diseases. The cell differentiation and morphology of benign bronchial and pulmonary tumors are similar to normal cells. Most of the masses have capsules, are clearly demarcated from the surrounding tissues, have smooth and neat edges, are round or oval, and are mostly solid lesions. They are more distributed on the right side than on the left side, and the tissues are well differentiated, but some benign tumors may become malignant.

[0003] Clinically, when sampling lung cancer tumors, direct sampling is generally performed using a puncture needle. This will damage the lung cancer tumor tissue and cause the cancer cells to flow and spread outward, which may cause engulfment and damage to good tissues. In addition, when sampling, the sampled tumor cells are also easily destroyed, affecting the analysis of the sample. How to prevent cancer cells from spreading outward during sampling is a direction that needs to be studied. Therefore, the inventor team invented a lung cancer tumor sampling device and a method of use to solve the problem of tumor sampling. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a lung cancer tumor sampling device and a method of using the same.

[0005] The present invention is achieved through the following technical solutions:

[0006] A lung cancer tumor sampling device and a method of using the same include a control box, a ventilation tube is sleeved in the control box, a puncture needle is installed at the right end of the ventilation tube, so that the puncture needle and the ventilation tube are an integrated structure, a pull rope and a threading rope are passed through the ventilation tube and the puncture needle, the pull rope and the threading rope are an integrated thin rope, a positioning ring is installed at the right end of the pull rope, a pressure block is symmetrically installed on the left side of the ventilation tube surface, a third coil spring is fixedly installed between the ventilation tube and the left end inside the control box, through grooves are opened on both side walls of the control box, a grip block is arranged below the control box, a connecting rope is fixedly connected between the grip block and the control box, the grip block is fixedly connected to the threading rope, a first A rotating plate, a rotating member is installed between the first rotating plate and the control box, a second coil spring is connected between the surface of the first rotating plate and the control box, a top block is fixedly installed on a side of the first rotating plate close to the control box, a second rotating plate is hingedly installed at the rightmost end of the first rotating plate, a first coil spring is installed between the second rotating plate and the surface of the first rotating plate, a ventilator is arranged on the left side of the control box, a mounting pipe is connected between the ventilator and the ventilation pipe, the ventilator is fixedly installed between the control box, rubber heads are symmetrically installed at both ends of the ventilator, a pull ring is fixedly installed on the left side of the ventilator, and a connecting pipe is connected between the ventilator and the ventilation pipe. The lung cancer tumor sampling device also includes the following method steps:

[0007] S1. The positioning ring is initially set vertically at the end of the puncture needle. At the starting position, the pressure block is stuck in the through groove, and the puncture needle is in a retracted state. A spring is installed in the pressure block. The doctor holds the pull ring and moves the sampling device to the vicinity of the patient's tumor puncture position.

[0008] S2, perform puncture first. During puncture, the doctor holds the first rotating plate and pushes the first rotating plate toward the control box. The top block pushes the pressure block and pushes the top block from the through slot into the control box. The elastic force of the third coil spring will push the puncture needle into the tumor position and push the threading rope to push the positioning ring out of the puncture needle. Through the auxiliary observation of the endoscope, the positioning ring is sleeved outside the tumor tissue. Through the constraint of the positioning ring, the blood circulation of the tumor tissue is stopped locally, so that local tissue cells are necrotic, thereby preventing a large number of tumor cells from flowing out and spreading when the tumor tissue is destroyed. Then, the threading rope is pulled to pull the positioning ring with the tumor tissue to the puncture needle port position. There is a groove at the puncture needle port position, which is also convenient for pulling the positioning ring into the puncture needle by pulling the pull rope. By squeezing the second rotating plate and using the rubber head, the tumor tissue can be sucked into the puncture needle, and sampling is performed using the sampling port in the puncture needle. At this time, when sampling, the tumor tissue has been constrained and the cells of the tumor tissue will not flow everywhere.

[0009] S3. After the above steps are performed, the sampling device is finally pulled out, the sampled tumor cell tissue is removed for testing, and the patient's lesion condition is observed. The sampling of the sampling device can constrain the tumor tissue before sampling, which ensures the stability of the sampling and reduces the accidental spread of tumor cells after the tumor tissue is destroyed.

[0010] Preferably, the positioning ring is made of PPSU material and has an annular structure. The positioning ring is sleeved outside the draw rope so that the right end of the draw rope forms an annular structure.

[0011] Preferably, a slot is provided at the right port of the puncture needle, and the puncture needle is connected to the ventilation tube.

[0012] Preferably, the drawing rope and the pulling rope are both composed of wires with a diameter of 3-5 mm, and the pulling rope and the drawing rope are both made of polyester fiber material.

[0013] Preferably, the pressing block and the top block are both made of rubber material, both are hemispherical structures, and a spring is installed in the pressing block.

[0014] Preferably, the first rotating plate and the rotating member are movably assembled, and the first rotating plate and the second rotating plate are movably assembled.

[0015] Preferably, the vent cylinder is communicated with the rubber head, the vent cylinder is communicated with the connecting pipe, the connecting pipe is communicated with the vent pipe, and the connecting pipe is a rubber hose.

[0016] Preferably, the grip block is a cylindrical structure, a rubber sleeve is sheathed on the outside of the grip block, and the grip block is fixedly connected to the threading rope.

[0017] Preferably, the puncture needle and the control box are slidably matched.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention can form an annular structure at the rightmost end of the pull rope through the setting of the positioning ring, and the annular structure is sleeved outside the tumor tissue. By tightening, the tumor tissue can be locally bound. By binding, the blood circulation of the tumor tissue is reduced, and local cells are necrotized, so that a large number of cancer cells are prevented from flowing outward and spreading when sampling. By controlling the pressure block and the elastic force of the third coil spring, the puncture needle can be ejected for puncture. By combining the rubber head and the puncture needle, the tumor tissue can be adsorbed at the position of the puncture needle needle by negative pressure, which is convenient for sampling. The present invention cleverly forms an annular structure of the pull rope through the positioning ring, and uses the annular part to bind the tumor tissue to prevent the spread of tumor cells, thereby reducing the spread of cancer cells when sampling, and can also perform accurate sampling.
