摘要： A precision depth guided instrument, such as a Jamshidi needle, is provided for use in various surgeries related to the vertebrae. The instrument includes an outer cannula, an inner cannula and a stylet. After the cortical bone of a vertebra is penetrated by the outer cannula of the instrument, the depth of penetration of the inner cannula is adjusted by rotation of the inner cannula. The inner cannula is then moved further into the vertebrae, and a stop mounted on the outer cannula controls the depth of penetration of the inner cannula. The correct depth of penetration is determined by radiography prior to the procedure.

摘要： A surgical guide wire or K-wire and method of use are provided. The K-wire or guide wire has opposite end portions and a shank portion in between. One end portion has a deformable end portion that, once outside of a confining guide passage, can be deformed to present a projected forward facing area that is larger than the transverse cross section of the K-wire or guide wire while in the passage. The increased area will provide increased resistance to additional forward axial movement into the surgical site.

摘要翻译： 提供外科导丝或K线及其使用方法。 K线或导线具有相对的端部和两者之间的柄部分。 一端部具有可变形的端部，其一旦在限制导向通道的外侧可以变形，以在通道中呈现比K线或导丝的横截面大的突出的向前区域。 增加的面积将增加抵抗进一步向前轴向移动到外科手术部位的阻力。
