一种微创手术刨削凝血装置A minimally invasive surgical planing coagulation device

技术领域technical field

本发明属于医疗设备领域，尤其涉及一种微创手术刨削凝血装置。The invention belongs to the field of medical equipment, in particular to a minimally invasive surgical planing and coagulation device.

背景技术Background technique

微创手术顾名思义就是微小创伤的手术，一般利用腹腔镜、胸腔镜等现代医疗器械及相关设备进行手术，微创手术的优点是创伤小、疼痛轻、恢复快，而这是每个需要手术的病人的梦想，微创外科使这个梦想成为了现实。随着科学技术的发展进步，“微创”这一概念已深入到外科手术的各种领域，监控系统也不仅限于内窥镜，更多是采用介入的方式，如脊柱外科、骨科，还有其他的方式，如显微外科广泛应用于手外科等。Minimally invasive surgery, as its name implies, is a minimally invasive surgery. It is generally performed using modern medical devices such as laparoscopes and thoracoscopes and related equipment. The advantages of minimally invasive surgery are that the trauma is small, the pain is light, and the recovery is fast. A patient's dream, minimally invasive surgery makes this dream a reality. With the development and progress of science and technology, the concept of "minimally invasive" has penetrated into various fields of surgery, and monitoring systems are not limited to endoscopes, but also use interventional methods, such as spine surgery, orthopedics, and Other modalities, such as microsurgery, are widely used in hand surgery.

目前，微创手术中会用到等离子凝血技术，该技术属于等离子手术系统，除此之外微创手术中也会用到一种刨削刀头，该刨削刀头隶属于手术动力系统，主要作用是刨削病患处的病灶软组织结构，刨削病灶软组织时会出现出血，此时需要更换手术器械(凝血手术器械)，而更换过程较长，可能造成出血量大，凝血时间长的情况，增加了微创手术的风险，不利于患者后续的康复，此外，在刨削和凝血操作时还需要吸引器械将病灶处杂质和积液吸除。At present, plasma coagulation technology is used in minimally invasive surgery, which belongs to the plasma surgery system. In addition, a planing cutter head is also used in minimally invasive surgery, which belongs to the surgical power system. The main function is to shave the soft tissue structure of the lesion at the affected area. Bleeding will occur when shaving the soft tissue of the lesion. At this time, the surgical instrument (coagulation surgical instrument) needs to be replaced, and the replacement process is long, which may cause a large amount of bleeding and a long coagulation time. This increases the risk of minimally invasive surgery and is not conducive to the patient's subsequent recovery. In addition, suction instruments are required to remove impurities and fluid from the lesion during planing and coagulation operations.
