In transsphenoidal resection of pituitary tumors, even dedicated instruments sometimes cannot readily reach the surgical fields and they interfere with the endoscope and other instruments, making instrumental manipulations difficult and often ineffective. To solve these problems, we invented a bendable ring curette to further improve maneuverability and accessibility.
The newly developed ring curette has a tip (14-mm long) that can bend spanning a range of 90°. Two types of ring curette are constructed; an upward-bending type, and a downward-bending type. We used the ring curette in 222 endoscopic pituitary surgeries.
The ring curette was easily operated with one hand, simply by manipulating the slider located at the handle to bend or straighten the tip. The bendable ring curette permits adequate access to sites where regular dedicated instruments such as the fixed-angle ring curette could not reach easily. The ring curette facilitated tumor resection as long as tumors were not too hard. Furthermore, the curette could be used as a dissector because the long tip provides greater horizontal and vertical forces.
Our newly developed bendable ring curette improves maneuverability and accessibility and can be efficiently used as a dissector in the far lateral and frontal sites, compared with the conventional fixed instrument.
在经蝶窦垂体瘤切除术，即使是专用器械有时也难以到达手术区域，并与内窥镜和其他器械发生干涉，导致器械操作困难且往往无效。为了解决这些问题，我们发明了一种可弯曲的环形刮匙，以进一步提高可操作性和可及性。
新开发的环形刮匙的尖端（长 14mm）可弯曲 90°的范围。有两种类型的环形刮匙，一种是向上弯曲型，另一种是向下弯曲型。我们在 222 例内镜垂体手术中使用了环形刮匙。
环形刮匙可以单手轻松操作，只需通过操纵手柄上的滑块弯曲或伸直尖端即可。可弯曲的环形刮匙允许到达常规专用器械（如固定角度环形刮匙）难以轻易到达的部位。只要肿瘤不是太硬，环形刮匙就可以促进肿瘤切除。此外，由于长尖端提供更大的水平和垂直力，因此该刮匙可用作剥离器。
与传统的固定器械相比，我们新开发的可弯曲环形刮匙提高了可操作性和可及性，并可作为远外侧和额部的剥离器高效使用。
