Description

Technical Field

[0001] The invention relates to the technical field of tumor sampling, in particular to a tumor specimen sampler. Background Art

[0002] In actual clinical tumor diagnosis and treatment, bone tumors are common tumor lesions, which mostly occur in bones or originate from various bone tissue components. Benign primary bone tumors are more common than malignant ones, and diagnosis requires a combination of clinical, imaging and pathological examinations. Because they occur in the bone layer, especially intrabone tumors, sampling requires puncturing hard bone, and a high-strength puncture needle is required. Tumor sampling is also accompanied by the risk of lesion spread. Current tumor specimen samplers are widely used due to their simple structure and flexible use. However, current tumor specimen samplers are not easy to retain and prevent diffusion. After sampling is completed, the puncture site is prone to diffusion when the puncture needle is pulled out. The puncture needle will also contaminate normal tissues, and it is not easy to fit the puncture site to prevent diffusion. Once diffusion occurs, it will affect the effect of subsequent surgical treatment. At the same time, it is not easy to perform isolated sampling.

The balloon 203 is installed on the drilling bit 201; the inner side of the drilling bit 201 is connected to the balloon 203 through a circle of through holes; the balloon 203 is used to expand and fit the tumor sampling site. The bone drilling piece 2 is used, which can be more suitable for patients with bone tumors. It can assist doctors to drill into the bone and quickly extract and sample. At the same time, the drilling bit 201 uses the rotation process to drive the rotary slice 202 to rotate, which can facilitate the scraping of tumor specimens. The structure is simple and reasonable. At the same time, the more important role of this structure is that this structure can achieve retention protection. The drilling bit 201 can be retained at the patient's tumor sampling site to prevent the direct removal of the drilling bit 201 from causing the spread of the lesion. The structure is simple to use and has efficient sampling. When the drilling bit 201 drills into the bone, the rotary slice 202 can scrape the bone and tumor specimens to assist in increasing the success rate of sampling. When sampling, medical imaging equipment should be used to pay attention to the sampling installation tube 101 should not contact the tumor tissue.

This structure utilizes a retention protection method to more effectively reduce the risk of lesion spread, and can facilitate subsequent treatment after the doctor conducts pathological research and confirmation. For example, if a malignant lesion exists, the drilling bit 201 can be removed in a subsequent operation. If it is a benign tumor, the drilling bit 201 can be directly removed. The structure is more reasonable, and an independently removed sampling installation tube 101 is used. It does not participate in the sampling of the tumor and will not contact the punctured tumor. When the sampling installation tube 101 is removed, it will not cause the spread of the lesion. After rotating and disassembling and tightening the threaded sleeve 303, the sampling installation tube 101 can be pulled out. At this time, the hexagonal slot 1011 on the sampling installation tube 101 is naturally separated from the plug-in hexagonal block 2011. The plug-in method utilizes the plug-in hexagonal block 2011 to limit the plug-in hexagonal slot 1011, which is convenient for rotating the sampling installation tube 101 to drive the drilling bit 201 to rotate and drill into the bone.

The specimen extraction member 5 can be used for isolated sampling, which can facilitate the extraction of tumor specimens by the staff. By means of isolation, the complexity of subsequent separation of specimens from the blood is reduced, the operation is simple, and the efficiency of the overall sampling process is improved. At the same time, it is convenient to take out the specimen inside the traction hose 301 as a whole, and prevent excessive specimens from being retained inside the traction hose 301, resulting in sampling waste. The tumor specimen can be extracted by docking the syringe with the docking sleeve 502 for suction. The tumor specimen particles can be isolated by the isolation net 503. The docking sleeve 502 and the extraction sheet 501 can be extracted by the friction force of the syringe and the docking sleeve 502.

[0037] Embodiment 2, on the basis of embodiment 1, the diffusion-proof inflatable member 4 comprises: a pressurized docking sleeve 401 and a docking rubber sleeve 4011, the docking rubber sleeve 4011 is fixedly mounted on the pressurized docking sleeve 401, and the docking rubber sleeve 4011 is sealed and sleeved on the threaded connecting pipe 302; the tail of the pressurized docking sleeve 401 is used for docking the syringe for inflation; the diffusion-proof inflatable member 4 also comprises: a closed rubber ring 402, a limit mounting ring 403, a propulsion spring 404, an elastic limit ring 4041 and a closed ball 405, the closed rubber ring 402 is fixed The fixed sleeve is connected inside the pressurized docking sleeve 401; the inner side of the closed rubber ring 402 is a slope structure; the pressurized docking sleeve 401 is fixedly connected inside the limited mounting ring 403, and the limited mounting ring 403 is fixedly installed with a propulsion spring 404; the end of the propulsion spring 404 is fixedly installed with an elastic limiting ring 4041; a closed ball 405 is attached to the closed rubber ring 402; the elastic limiting ring 4041 elastically fits the closed ball 405; the closed ball 405 is used to close and fit the closed rubber ring 402, and the use of the anti-diffusion inflatable member 4 can facilitate work The personnel can further ensure the sealing and anti-diffusion effect of the puncture wound, and can further reduce the probability of tumor puncture wound diffusion. The flexible fit of the balloon 203 is more suitable for irregular bone surfaces, so that the puncture position is in an isolated state, which is convenient for doctors to formulate treatment plans after fully testing the tumor specimens after sampling, and reduce the probability of lesion diffusion during this period. The structure is simple and practical. The structure can be quickly inflated with a syringe, and can achieve automatic sealing and anti-leakage, avoiding doctors forgetting to operate and causing leakage. The overall structure is simple and cost-effective. The invention has low cost and plays a positive role in preventing the existing tumor specimens from spreading. The pressurized docking sleeve 401 is connected to the syringe for inflation. At this time, under the action of air pressure, the blocking column 5011 keeps sealing and fitting the sampling slot 2012. The air pressure will be filled into the balloon 203, and the balloon 203 can expand and fit the sampling puncture position to isolate and reduce the probability of diffusion. At the same time, when the syringe is pulled out, the sealing ball 405 can seal and fit the sealing rubber ring 402 to achieve one-way controlled sealing. The overall structure is simpler and more reasonable, and the expansion and fit are tight.

[0038] The working principle of this embodiment is as follows: First, the hand-held handle 102 is held and the drilling bit 201 is drilled into the tumor lesion. At this time, as the drilling bit 201 rotates and drills into the bone, the rotary slice 202 can scrape the bone and the tumor specimen. After the drilling bit 201 drills into the bone, a section of the extraction sheet 501 is first pulled outward so that the blocking column 5011 and the sampling slot 2012 are no longer fitted and blocked, and the docking sleeve 502 is kept plugged into the threaded connecting tube 302. Whether it is an intrabone tumor or Extra-bone tumors can be cut by the rotary slicer 202 to produce fragments. At this time, the syringe is connected to the docking sleeve 502 for suction. At this time, the blocking column 5011 will not block the suction of tumor fragments inside the cone-shaped drilling drill 201, and the tumor specimen can be extracted. The tumor specimen particles can be isolated by the isolation net 503. The docking sleeve 502 and the extraction sheet 501 can be pulled out through the friction between the syringe and the docking sleeve 502. The blocking column 5011 can assist in pushing out the tumor specimen.

[0039] After the sampling is completed, the threaded sleeve 303 is rotated and disassembled to tighten the sampling installation tube 101, and the hexagonal slot 1011 on the sampling installation tube 101 is naturally separated from the plug-in hexagonal block 2011. At this time, the medical staff disinfects and bandages the wound between the traction hose 301 and the body surface and waits for the tumor pathology report; the docking sleeve 502 is fully inserted into the threaded connecting tube 302, and the blocking column 5011 is sealed and fits the sampling slot 2012, and the docking rubber sleeve 4011 is sleeved on the threaded connecting tube 302. The grooved connecting tube 302 is connected to the pressurized docking sleeve 401 to inflate the syringe. Under the action of air pressure, the blocking column 5011 keeps sealing and fitting the sampling slot 2012. The air pressure will be filled into the balloon 203, and the balloon 203 can expand and fit the sampling puncture position to isolate and reduce the probability of diffusion. At the same time, when the syringe is pulled out, under the action of the internal air pressure of the balloon 203, the closing ball 405 can close and fit the closing rubber ring 402 to seal and maintain the air pressure with the extrusion of the propulsion spring 404.
