    Abstract: A tissue splitter for creating a subcutaneous cut is disclosed. The tissue splitter includes a retractable blade located at the distal end. The tissue splitter is configured to be insertable into a slotted cannula that is placed via an incision to a location proximate a patient's spine. An actuator at the proximal end of the instrument projects the blade located at the distal end from its retracted state through the slot of the cannula to an extracted state to subcutaneously cut tissue at a location outside the cannula. The instrument is configured such that the blade is movable inside the slot of the cannula by a distance such that the cut created by the blade remains subcutaneous and does not puncture the skin of the patient. The distance is adjustable for the size and depth of the cut and is limited by an adjustment collar. The tissue splitter is ideally suited for creating a pathway for the subcutaneous insertion and implantation of a spinal stabilization rod between two bone anchors placed in vertebral bodies.

    Abstract: One embodiment of the present invention relates to a prosthesis, comprising: an acetabular cup, wherein the cup has an open end and a closed end, wherein the open end of the cup is defined by a rim and wherein the rim has an outer facing surface; at least one cavity disposed in the rim, wherein the cavity extends from a first end of the cavity at the outer facing surface to a second end of the cavity that is towards the closed end of the cup, and wherein the cavity comprises an undercut at the second end of the cavity; a locking ring; and at least one tab extending from the locking ring, wherein the tab comprises a first leg and a second leg having a separation therebetween, wherein each leg has a first end and a second end, wherein the first end of each leg is at the locking ring, wherein the second end of the first leg comprises a tab protrusion, and wherein at least the second leg is resilient such that the separation between the first leg and the second leg is reduced when the second leg is deflected towards the first leg; wherein the locking ring is removably locked to the cup by placement of the locking ring adjacent the rim and insertion of the tab into the cavity such that the second leg presses against a sidewall of the cavity to initially deflect the second leg towards the first leg as the tab enters the cavity and the tab protrusion of the first leg is urged into the undercut by the second leg subsequently deflecting back away from the first leg.

    Abstract translation: 本发明的一个实施例涉及一种假体，包括：髋臼杯，其中杯具有开口端和封闭端，其中杯的开口端由边缘限定，并且其中边缘具有外表面 ; 设置在所述边缘中的至少一个空腔，其中所述空腔从所述空腔的位于外表面的第一端延伸到所述空腔的朝向所述杯的封闭端的第二端，并且其中所述腔包括 空腔的第二端; 锁环; 以及从所述锁定环延伸的至少一个突片，其中所述突片包括第一腿部和第二腿部，所述第一腿部和第二腿部之间具有间隔，其中每个腿部具有第一端部和第二端部，其中每个腿部的第一端部处于锁定 环，其中所述第一腿的第二端包括突出部，并且其中至少所述第二腿具有弹性，使得当所述第二腿朝向所述第一腿偏转时，所述第一腿和所述第二腿之间的间隔减小; 其中所述锁定环通过将所述锁定环放置在所述边缘附近并将所述突片插入所述腔中而可拆卸地锁定到所述杯，使得所述第二腿压靠所述腔的侧壁以使所述第二腿最初偏向所述第一腿， 突片进入腔体，第一腿部的舌片突出部被第二腿部推动进入底切部分，随后从第一腿部向后偏转。
