Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical sampling equipment, and in particular to a lung cancer tumor sampling device and a method of using the same. Background Art
[0002] A tumor is a new growth formed by the proliferation of local tissue cells under the action of various tumorigenic factors. Because this new growth often appears as a space-occupying, mass-like protrusion, it is also called a neoplasm. Lung cancer is one of the most common malignant tumors and also has the highest incidence rate. Scientific research on lung cancer has been actively carried out throughout the world. During clinical treatment, lung cancer tissue specimens obtained through surgery are pathologically evaluated to determine whether it is a malignant tumor, thus providing a basis for clinicians to make treatment decisions.
[0003] The existing lung cancer tumor sampling method usually involves first disinfecting, anesthetizing and making an incision on the patient's skin in the area to be sampled, then inserting a guide needle into the tumor area and pulling out the needle core, and then inserting a biopsy gun through the guide needle into the tumor area for sampling. The existing tumor sampling devices all rely on medical staff to perform manual puncture. The insertion of the guide needle and 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. After the needle core is pulled out, the top of the guide needle is prone to overflowing with the patient's blood, and flowing 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 biopsy gun into the patient's skin into the tumor area for sampling, avoids cell damage due to hand tremors, and avoids heavy bleeding and infection caused by the patient in the first time after the needle core is pulled out.

[0011] Preferably, the method for using the lung cancer tumor sampling device comprises the following steps:
[0012] S1: When using this device, the patient is first asked to lie flat on the operating table with their back facing upwards. The area on the patient's back to be sampled is then disinfected and anesthetized. An incision is then made in that area. The guide needle is then manually fixed to the manual clamping assembly. The position and angle of the guide needle are then adjusted with the help of the position adjustment device to facilitate the control of the guide needle to puncture the patient's back into the tumor area for sampling.
[0013] S2: After adjusting the position of the guide needle, the guide needle is controlled to descend along the first auxiliary sampling assembly, gradually passing through the patient's back and entering the tumor area. The manual clamping assembly is then controlled to release the clamp on the guide needle and fix the top of the needle core. The needle core is then controlled to ascend along the first auxiliary sampling assembly, thereby separating the needle core from the guide needle.
[0014] 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 directly above the guide needle. At this time, the automatic blocking component releases the blockage 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 passes through the inner cavity of the guide needle and enters the patient's tumor sampling area for sampling.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In the present invention, the position and angle of the guide needle need to be adjusted according to the position of the tumor area to be sampled in the patient. First, the two locking wheels are rotated to release the locking block from the abutment with the bottom of the slide rail, and then the mounting rod is pushed to slide longitudinally on the two slide rails. After the position is adjusted, the two locking wheels are rotated 90 degrees to make the locking block abut against the slide rail, thereby locking the position of the mounting rod. Then, the adjusting disk is rotated 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 disengaging the locking rods from both sides of the sliding block and the ball head connector. Then, the sliding block is controlled to slide horizontally on the upper part of the mounting rod, and the position and angle of the guide needle are adjusted 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 toward the opposite side, thereby driving the two locking rods to move synchronously toward the opposite side, thereby locking both sides of the sliding block and the ball head connector, thereby locking the position of the guide needle, thereby facilitating subsequent tumor sampling operations.
[0017] In the present invention, when the guide needle needs to be inserted, the upper end of the guide needle is first placed between the two clamping rods and the top of the guide needle is aligned with the center of the mounting part. Then, the handle is manually pulled to drive the support rod to slide toward the outside of the clamping box. Under the cooperation of the third connecting rod and the gear plate, the two clamping rods are synchronously driven to slide toward the opposite side, thereby controlling the two clamping rods to fix the top of the guide needle. 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 patient's back into the tumor area, thereby avoiding the problem of cell damage caused by hand shaking. After the guide needle is inserted, the handle is released and the support rod is reset under the action of the second spring, thereby releasing the fixation of the top of the guide needle. Then, the clamping box is driven to move slightly upward until the two clamping rods are located on both sides of the top of the needle core. The handle is continued to be pulled to drive the two clamping rods to fix the top of the needle core. Then, under the action of the first spring, the moving block is driven to rise and reset, thereby separating the needle core from the guide needle, so that the biopsy gun can insert the guide needle for sampling.
[0018] 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 switches from a horizontal state to a vertical state and moves away from the bottom of the mounting member. Then, the second rotating rod is rotated so that the sampling end of the biopsy gun corresponds to the center of the circle at the bottom of the mounting member. 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.
[0019] 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, causing the sealing plate to rise. 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, avoiding excessive blood overflowing from the top of the guide needle and causing problems such as infection. At the same time, the sealing tape at the bottom of the sealing block can be replaced to facilitate the continued use of the sealing block. BRIEF DESCRIPTION OF THE DRAWINGS

The biopsy gun 63 is arranged at the side end of the moving block 312 in the second auxiliary sampling assembly 62.
[0042] After the needle core 5 is pulled out, the second connecting rod 33 is rotated upward to a vertical state, so that the manual clamping assembly 34 is switched from a horizontal state to a vertical state and thus away from the bottom of the mounting member 243. Then, the second rotating rod 612 is rotated so that the sampling end of the biopsy gun 63 corresponds to the center of the circle at the bottom of the mounting member 243. Then, the moving block 312 is pulled downward to drive the biopsy gun 63 to descend, and its sampling end passes through the inner cavity of the guide needle 4 into the patient's tumor sampling area for sampling.
[0043] In this embodiment, Figures 11 to 12As shown, the automatic plugging assembly 64 includes a fixing rod 641, a sealing box 642, a sealing block 643, a third spring 644 and a sealing plate 645. The fixing rod 641 is vertically arranged at the bottom of the second rotating rod 612, the sealing box 642 is horizontally arranged at the bottom of the fixing rod 641, the sealing block 643 passes through one side of the sealing box 642 and is slidably connected to it, the third spring 644 is arranged inside the sealing box 642 and the two ends of the third spring 644 are respectively connected to the sealing plate 645. The block 643 is connected to the side end of the sealing box 642. The bottom of the sealing block 643 is detachably provided with a sealing tape. The sealing plate 645 vertically passes through the top of the sealing box 642 away from the fixing rod 641. The bottom of the sealing plate 645 is stopped at the side end of the sealing block 643. A protrusion is provided on one side of the sealing plate 645 and the protrusion is located directly above the clamping box 341. The other side of the sealing plate 645 is connected to the side end of the fixing rod 641 for sliding up and down.
[0044] When the needle core 5 is completely taken out by the manual clamping assembly 34, as the clamping box 341 rises to the top, the clamping box 341 drives the protrusion to rise, causing the sealing plate 645 to rise. As the sealing plate 645 rises, the side end of the sealing block 643 loses its resistance, and the third spring 644 is released to drive the sealing block 643 to pop out, and then drive the bottom of the sealing block 643 to seal the top of the guide needle 4, avoiding excessive blood overflowing from the top of the guide needle 4 and causing infection and other problems. At the same time, the sealing tape at the bottom of the sealing block 643 can be replaced to facilitate the continued use of the sealing block 643.
[0045] The method of use and advantages of the present invention: The method of use of the lung cancer tumor sampling device, the working process is as follows:
[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 As shown:
[0047] S1: When using the device, the patient is first asked to lie flat on the operating bed 1 with their back facing upwards. The area on the patient's back to be sampled is then disinfected and anesthetized. An incision is then made in the area. The guide needle 4 is then manually fixed to the manual clamping assembly 34. The position and angle of the guide needle 4 are adjusted with the cooperation of the position adjustment device 2 to facilitate control of the guide needle 4 to puncture the patient's back into the tumor area for sampling.
[0048] S2: After adjusting the position of the guide needle 4, the guide needle 4 is controlled to descend along the first auxiliary sampling assembly 31, gradually passing through the patient's back and entering the tumor area. The manual clamping assembly 34 is then controlled to release the clamping of the guide needle 4 and fix the top of the needle core 5. The needle core 5 is then controlled to ascend along the first auxiliary sampling assembly 31, thereby separating the needle core 5 from the guide needle 4.
[0049] S3: When the needle core 5 is completely separated from the guide needle 4, the automatic blocking component 64 is triggered to seal the top of the guide needle 4 to prevent excessive blood from overflowing from the top of the guide needle 4. The biopsy gun 63 is then controlled to move directly above the guide needle 4. At this time, the automatic blocking component 64 releases the blockage on the top of the guide needle 4, and then drives the biopsy gun 63 to descend with the cooperation of the second auxiliary sampling component 62. The sampling end of the biopsy gun passes through the inner cavity of the guide needle 4 and enters the patient's tumor sampling area for sampling.
