本发明涉及医疗器械技术领域，具体是一种脊柱外科手术专用复合碎骨装置。The invention relates to the technical field of medical devices, in particular to a special composite bone crushing device for spinal surgery.
背景技术Background technique
脊椎是由不同的椎体通过前面的椎间盘和后面的两个小关节连接而成，这关节允许脊椎弯曲和扭转，随着年龄增大或遭遇外伤后，这些关节可能会磨损或者退变，从而出现疼痛。这时就需要通过药物或者手术方法来稳定脊椎发生关节炎的部位，如果物理和药物治疗无法控制疼痛，就需要进行手术治疗，但是各种内固定，其所建立的稳定都是暂时的，随着时间的推移，其固定作用必将逐渐减弱，由其所建立的稳定性也随之失去，这就需要通过脊柱融合手术来获得永久的稳定。The spine is composed of different vertebral bodies connected by an intervertebral disc in the front and two small joints in the back. These joints allow the spine to bend and twist. With age or after trauma, these joints may wear or degenerate, thus Pain occurs. At this time, it is necessary to stabilize the arthritic part of the spine through drugs or surgery. If physical and drug treatments cannot control the pain, surgery is required. However, the stability established by various internal fixations is temporary. As time goes on, its fixation will gradually weaken, and the stability established by it will also be lost, which requires spinal fusion surgery to obtain permanent stability.
在脊柱融合手术中，需要把从患者其它部位取出的骨头切成小颗粒，得到的碎骨颗粒用于相邻脊椎之间的填充支撑，最后在用碎骨粉末填充碎骨颗粒之间的小缝隙，以使病人达到治愈和缓解的目的，目前，现在手术中用到的碎骨，通常都是使用碎骨钳和手术剪来把骨头切成小颗粒。In the spinal fusion operation, it is necessary to cut the bone taken from other parts of the patient into small particles, and the obtained bone particles are used for filling and supporting between adjacent vertebrae, and finally the small bone particles between the bone particles are filled with crushed bone powder. Gap, so that the patient achieves the purpose of healing and relief, at present, the bone fragments used in the operation now usually use pliers and surgical scissors to cut the bone into small particles.
但是，上述的脊柱碎骨方法存在下列弊端：But there are following drawbacks in the above-mentioned vertebral bone crushing method:
1.使用碎骨钳或手术剪所切下的骨头颗粒大小不均匀；1. The size of the bone particles cut by bone crusher or surgical scissors is not uniform;
2.现有的碎骨方法剪下来的颗粒，有的会带有突刺，填充到脊柱里后会让病人产生疼痛；2. Some of the particles cut out by the existing bone crushing method will have spikes, which will cause pain to the patient after being filled into the spine;
3.现有碎骨装置功能单一，只能剪成颗粒状碎骨，需要利用其他工具才能得到骨头粉末；3. The existing bone crushing device has a single function and can only be cut into granular crushed bones, and other tools are needed to obtain bone powder;
4.使用碎骨钳或手术剪碎骨时，需要人手用力握紧碎骨钳或手术剪，不仅费时费力，还容易造成碎骨四处乱溅；4. When using bone crushers or surgical scissors to crush bones, it is necessary to hold the bone crushers or surgical scissors tightly by hand, which is not only time-consuming and laborious, but also easily causes the broken bones to splash around;
因此，本发明提供一种脊柱外科手术专用复合碎骨装置来解决上述问题。Therefore, the present invention provides a special composite bone crushing device for spinal surgery to solve the above problems.
