一种骨肿瘤穿刺活检用负压旋切穿刺套管A kind of negative pressure rotary cutting puncture sleeve for bone tumor puncture biopsy

技术领域technical field

本发明涉及骨肿瘤治疗技术领域，尤其涉及一种骨肿瘤穿刺活检用负压旋切穿刺套管。The invention relates to the technical field of bone tumor treatment, in particular to a negative pressure rotary cutting puncture sleeve for bone tumor puncture biopsy.

背景技术Background technique

骨肿瘤是发生于骨骼或其附属组织的肿瘤。有良性，恶性之分，良性骨肿瘤易根治，预后良好，恶性骨肿瘤发展迅速，预后不佳，死亡率高。恶性骨肿瘤分为原发性和继发性，从体内其他组织或器官的恶性肿瘤经血液循环、淋巴系统转移至骨骼为继发性恶性骨肿瘤，还有一类病损称瘤样病变，肿瘤样病变的组织不具有肿瘤细胞形态的特点，但其生态和行为都具有肿瘤的破坏性，一般较局限，易根治。Bone tumors are tumors that occur in the bone or its accessory tissues. There are benign and malignant. Benign bone tumors are easy to cure and have a good prognosis. Malignant bone tumors develop rapidly, have poor prognosis and high mortality. Malignant bone tumors are divided into primary and secondary. Malignant tumors from other tissues or organs in the body metastasize to bones through blood circulation and lymphatic system are secondary malignant bone tumors. There is another type of lesions called tumor-like lesions. Tumors Tissues with tumor-like lesions do not have the characteristics of tumor cell morphology, but their ecology and behavior are destructive to tumors, and are generally limited and easy to cure.

骨肿瘤的发病因素很复杂，目前还没有确切的病因，内因有素质学说、基因学说、内分泌学说等；外因有化学元素物质和内外照射慢性刺激学说，病毒感染学说等，部分多发性骨软骨瘤和纤维样增殖症与家族遗传有关，骨的良性肿瘤可以恶性变：如多发骨软骨瘤可恶变为软骨肉瘤。The pathogenic factors of bone tumors are very complex, and there is no definite cause at present. The internal causes include the theory of quality, genetics, and endocrine; the external causes include the theory of chemical elements, chronic stimulation of internal and external radiation, and virus infection. And fibrous hyperplasia is related to family inheritance, and benign tumors of bone can become malignant: for example, multiple osteochondromas can become chondrosarcoma.

现有技术中在对于骨肿瘤患者进行临床诊断时，需要用到穿刺套管进行活检取样，在医护人员通过手动按压将穿刺套管穿入活检部位时，容易因为手臂的抖动导致对于患者的活检部位的穿刺造成偏差，从而导致造成穿刺的位置不准确，继而不利于工作人员的使用，并且在医护人员长时间的工作下，容易导致肌肉酸痛，从容对于活检穿刺针的活塞部位的推动效果较差，不利于医护人员的使用。In the prior art, when clinically diagnosing bone tumor patients, a puncture cannula is required for biopsy sampling. When the medical staff manually presses the puncture cannula into the biopsy site, it is easy to cause the patient's biopsy failure due to shaking of the arm. The puncture of the part causes deviation, which leads to inaccurate puncture position, which is not conducive to the use of staff, and it is easy to cause muscle soreness under the long-term work of medical staff, and the effect of calmly pushing the piston part of the biopsy puncture needle Poor, not conducive to the use of medical staff.

工作原理：首先将吸盘16吸附于患者的皮肤表面，使第二穿刺针28位于病灶部位上方，接着调整针筒1和第一外板14，并旋动第一螺栓27，将调整到合适高度后的第一外板14和第一内板15进行限位稳定；Working principle: First, thesuction cup 16 is adsorbed on the patient's skin surface, so that thesecond puncture needle 28 is located above the lesion, and then the syringe 1 and the firstouter plate 14 are adjusted, and thefirst bolt 27 is rotated to adjust the height to a suitable height. The rear firstouter plate 14 and the firstinner plate 15 carry out position-limiting stabilization;

在将针筒1位置固定好后，旋动第一穿刺针6，使第三活塞5上的的第二开口与第二活塞4上的第一开口交错设置，使第一活塞3、第二活塞4、第三活塞5配合形成密闭空间；After fixing the position of the syringe 1, turn thefirst puncture needle 6 so that the second openings on thethird piston 5 and the first openings on thesecond piston 4 are alternately arranged, so that thefirst piston 3, the second Thepiston 4 and thethird piston 5 cooperate to form a closed space;

当需要对病灶部位进行穿刺时，将第二螺栓12旋出第二外板10内，接着支撑板20上方的伺服电机22开始工作，两个伺服电机22的旋动方向同时向内，带动转动杆21和齿轮23开始转动，齿轮23转动带动齿板25上下移动，此时第二移动板24和推动杆2以及第一活塞3整体下压，此时第二活塞4、第三活塞5、第一穿刺针6、旋动板29整体下移，通过第二穿刺针28实现对于病灶部位的穿刺，在此过程中，第二内板11在第二外板10内相对应的滑动；When it is necessary to puncture the lesion, thesecond bolt 12 is screwed out of the secondouter plate 10, and then theservo motor 22 above thesupport plate 20 starts to work, and the rotation direction of the twoservo motors 22 is inward at the same time, driving the rotation. Therod 21 and thegear 23 start to rotate, and thegear 23 rotates to drive thetoothed plate 25 to move up and down. At this time, the second movingplate 24, thepush rod 2 and thefirst piston 3 are pressed down as a whole. At this time, thesecond piston 4, thethird piston 5, Thefirst puncture needle 6 and therotating plate 29 move down as a whole, and thesecond puncture needle 28 realizes the puncture of the lesion. During this process, the secondinner plate 11 slides correspondingly in the secondouter plate 10;

当需要对病灶部位进行旋切时，医护人员旋动旋动板29，此时旋动板29带动第二穿刺针28转动，即可完成旋切操作，接着支撑板20上方的伺服电机22开始工作，两个伺服电机22的旋动方向同时向外，此时齿板25和第二移动板24整体上移，即可通过负压将第二穿刺针28内的病灶取样取出患者体内；When it is necessary to perform rotary cutting on the lesion, the medical personnel rotate therotating plate 29. At this time, the rotatingplate 29 drives thesecond puncture needle 28 to rotate, and the rotary cutting operation can be completed, and then theservo motor 22 above thesupport plate 20 starts work, the rotation directions of the twoservo motors 22 are outward at the same time, at this time thetooth plate 25 and the second movingplate 24 move up as a whole, and the lesion in thesecond puncture needle 28 can be sampled out of the patient's body through negative pressure;

其中需要补充的是，可以通过连接管8和环形取样收集管9完成对于病灶部位取样的收集，医护人员可通过穿刺针穿过丁基胶塞完成对于环形取样收集管9内取样的提取。What needs to be added is that the collection of samples from the lesion site can be completed through the connecting pipe 8 and the annularsampling collection tube 9 , and the medical staff can complete the extraction of the samples in the annularsampling collection tube 9 through the puncture needle through the butyl rubber stopper.
