技术领域Technical Field
本实用新型涉及妇科手术医疗器械领域，尤其涉及一种简易式妇科手术刨削器。The utility model relates to the field of gynecological surgical medical instruments, in particular to a simple gynecological surgical planer.
背景技术Background Art
在妇科相关手术中会使用刨削器来切除子宫肌瘤、子宫息肉等组织，这种刨削器以电机带动切刀往复旋切的方式来切除病变组织。由于手术在微创条件下进行，一方面可减轻患者痛苦，另一方面，手术造成的创伤较小，患者术后恢复快，同时，可降低了术后并发症。但现有的刨削器动力来源于主机，需要与配套的主机设备连接才能使用，单独购买配套的设备不仅成本高，而且无法将刨削器从主机设备上拆卸下来与目前的通用动力手柄连接，在使用上多有不便。In gynecological surgeries, a planer is used to remove uterine fibroids, uterine polyps and other tissues. This planer uses a motor to drive the cutter to reciprocate and rotate to remove the diseased tissue. Since the surgery is performed under minimally invasive conditions, on the one hand, it can reduce the patient's pain. On the other hand, the trauma caused by the surgery is small, and the patient recovers quickly after surgery. At the same time, it can reduce postoperative complications. However, the power of the existing planer comes from the host, and it needs to be connected to the matching host device before it can be used. Purchasing the matching equipment separately is not only costly, but also it is impossible to remove the planer from the host device and connect it to the current universal power handle, which is inconvenient in use.
