Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of orthopedic specimen sampling, in particular to a bone tumor pathology specimen sampler. Background Art
[0002] All tumors that occur in bones or originate from various bone tissue components, whether primary, secondary or metastatic, are collectively referred to as bone tumors. Common types include osteoid osteoma, osteochondroma, enchondroma, etc. Osteoid osteoma is hard in texture, close to the hardness of bone, while osteochondroma and enchondroma are relatively soft in texture, but still have a certain keratin hardness compared to soft tissues such as muscle. The pathology report of bone tumor needs to be obtained through analysis and testing of bone tumor pathology specimens, so it is necessary to sample the bone tissue at the tumor location for testing.
[0003] Existing bone tumor surgeries mostly use minimally invasive surgeries. The size of the incision at the surgical operation site is relatively small, and it is impossible to directly use conventional orthopedic samplers to scrape the tissue on the bone surface. Among minimally invasive surgical tools, the equipment used for specimen sampling is mostly tweezers and other equipment for sampling soft tissues, which do not have bone scraping function. When sampling hard keratinized tumor samples such as osteoid osteoma, it is impossible to effectively remove the bone specimen from the bone. In view of this, we propose a bone tumor pathology specimen sampler. Utility Model Content

[0024] Through the above structure, the rotating shaft 4 is rotated, and the rotating shaft 4 drives the arc scraper 5 to rotate inside the casing 1. The blade side of the arc scraper 5 passes through the opening of the sleeve 2, so that the end of the casing 1 and the sleeve 2 will not restrict the arc scraper 5. The casing 1 is rotated so that the blade of the arc scraper 5 can scrape the bones. As the casing 1 rotates, the scraped specimen is placed between the inner wall of the arc scraper 5 and the silicone sheet 8. The rotating shaft 4 is rotated in the opposite direction to retract the arc scraper 5 into the casing 1. The specimen is driven into the casing 1 by the multiple groups of barbs 7 on the inner wall of the arc scraper 5, so that the specimen is conveniently taken out from the patient's body. The cover body 3 is opened to take the specimen out from the inside of the casing 1. The specific structure is as follows:
[0025] Combined with Figure 2 and attached Figure 3 As shown, a strip mounting bracket 6 is installed between the rotating shaft 4 and the inner side of the arc scraper 5, one end of the rotating shaft 4 rotates to pass into the inside of the sleeve 2 and a movable sleeve 11 is sleeved on the outside, and the end of the movable sleeve 11 away from the sleeve shell 1 passes through the sleeve 2 and is connected to a rotating disk 14.
[0026] Through the above structure, the arc scraper 5 is stably mounted on the outside of the rotating shaft 4 through the strip mounting frame 6, and the rotating shaft 4 is driven to rotate by rotating the rotating disk 14, making the rotation of the rotating shaft 4 more labor-saving.
