Description

Technical Field

[0001] The present invention relates to the technical field of medical sampling equipment, in particular to a lung cancer tumor sampling device and a use method thereof. Background Art

[0002] Tumor refers to a new growth formed by the proliferation of local tissue cells under the action of various tumorigenic factors. Because this new growth is mostly space-occupying mass-like protrusions, it is also called a growth. Lung cancer is one of the most common malignant tumors and also the malignant tumor with the highest incidence. Scientific research on lung cancer has also been actively carried out in the world. In the process of clinical treatment, lung cancer tissue specimens obtained through surgery are pathologically evaluated to determine whether it is a malignant tumor, thereby providing a basis for clinical doctors to make treatment decisions; The existing lung cancer tumor sampling method usually first disinfects, anesthetizes and incises the patient's skin in the area to be sampled, then inserts a guide needle into the tumor area and pulls out the needle core, and then inserts the biopsy gun through the guide needle into the tumor area for sampling. The tumor sampling devices in the prior art all rely on medical staff to perform manual puncture. The insertion of the guide needle and the biopsy gun is too dependent on manual labor, lacks stability, and is prone to a series of hidden dangers such as damage to tumor cells. In addition, after the needle core is pulled out, the top of the guide needle is prone to overflowing with the patient's blood, and the blood flows out to the outside of the guide needle, causing infection and other risks. There is a lack of a device that assists surgical personnel in inserting the guide needle and the biopsy gun into the patient's skin into the tumor area for sampling, avoids cell damage due to hand shaking, and avoids infection caused by heavy bleeding of the patient as soon as possible after the needle core is pulled out.

[0010] Preferably, the method for using the lung cancer tumor sampling device comprises the following steps: S1: When using the device, first let the patient lie flat on the operating bed with his back facing upwards, then disinfect and anesthetize the area on the patient's back to be sampled, then make an incision on the area, then manually fix the guide needle to the manual clamping assembly, and adjust the position and angle of the guide needle with the cooperation of the position adjustment device, so as to control the guide needle to puncture the patient's back into the tumor area for sampling; S2: After adjusting the position of the guide needle, the guide needle is controlled to descend along the first auxiliary sampling assembly to gradually pass through the patient's back and enter the tumor area, and then the manual clamping assembly is controlled to release the clamping of the guide needle and fix the top of the needle core, and then the needle core is controlled to rise along the first auxiliary sampling assembly, thereby separating the needle core from the guide needle; S3: When the needle core is completely separated from the guide needle, the automatic blocking component is triggered to seal the top of the guide needle to prevent excessive blood from overflowing from the top of the guide needle. The biopsy gun is then controlled to move to just above the guide needle. At this time, the automatic blocking component releases the seal on the top of the guide needle, and then the biopsy gun is driven down with the cooperation of the second auxiliary sampling component. The sampling end of the biopsy gun passes through the inner cavity of the guide needle and enters the patient's tumor sampling area for sampling.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The two locking wheels are first rotated 90 degrees to make the locking block stop against the bottom of the slide rail, thereby locking the position of the mounting rod, and then rotating the adjusting disk to drive the driving gear to rotate, thereby driving the first toothed rod and the second toothed rod away from each other, so that the two locking rods are away from each other, thereby making the locking rod detach from the two sides of the sliding block and the ball head connector, and then controlling the sliding block to slide horizontally on the upper part of the mounting rod, and adjusting the position and angle of the guide needle by rotating the mounting member and the ball head connector. After the adjustment is completed, the adjusting disk is rotated in the opposite direction to make the first toothed rod and the second toothed rod move synchronously in the direction close to the opposite side, thereby driving the two locking rods to move synchronously in the direction close to the opposite side, thereby locking both sides of the sliding block and the ball head connector, and then locking the position of the guide needle, thereby facilitating subsequent tumor sampling operations.

[0012] In the present invention, when it is necessary to insert the guide needle, first, the upper end of the guide needle is placed between the two clamping rods and the top of the guide needle corresponds to the position of the center of the mounting part, then the handle is manually pulled to drive the support rod to slide to the outside of the clamping box, and the two clamping rods are driven to slide synchronously in the direction close to the opposite side under the cooperation of the third connecting rod and the gear plate, thereby controlling the two clamping rods to fix the top of the guide needle, and then the moving block is pulled downward so that the moving block moves downward along the sliding box, thereby driving the guide needle to move smoothly downward through the skin on the back of the patient into the tumor area, thereby avoiding the problem of cell damage caused by hand shaking and the like. After inserting the guide needle, release the handle and drive the support rod to reset under the action of the second spring, thereby releasing the fixation of the top of the guide needle, and then drive the clamping box to move slightly upward to the two clamping rods on both sides of the top of the needle core, continue to pull the handle to drive the two clamping rods to fix the top of the needle core, and then drive the moving block to rise and reset under the action of the first spring, thereby separating the needle core from the guide needle, so as to facilitate the subsequent insertion of the guide needle by the biopsy gun for sampling.

[0013] In the present invention, after the needle core is pulled out, the second connecting rod is rotated upward to a vertical state, so that the manual clamping assembly is switched from a horizontal state to a vertical state and then away from the bottom of the mounting member, and then the second rotating rod is rotated so that the sampling end of the biopsy gun corresponds to the position of the center of the circle at the bottom of the mounting member, and then the moving block is pulled downward to drive the biopsy gun to descend, and its sampling end passes through the inner cavity of the guide needle into the patient's tumor sampling area for sampling.

[0014] In the present invention, after the needle core is completely taken out by the manual clamping assembly, as the clamping box rises to the top, the clamping box drives the protrusion to rise so that the sealing plate rises. As the sealing plate rises, the side end of the sealing block loses its resistance, and the third spring is released to drive the sealing block to pop out, thereby driving the bottom of the sealing block to seal the top of the guide needle, thereby preventing excessive blood from overflowing from the top of the guide needle and causing infection and other problems. At the same time, the sealing tape at the bottom of the sealing block can be replaced to facilitate the continuous use of the sealing block. BRIEF DESCRIPTION OF THE DRAWINGS
