Targeting sleeve andknob assembly 定位套筒和旋钮组件
First assemble the knob to the targeting sleeve (Fig. 39a) and adjust the point on the knob to be in line with the arrow on the target sleeve. Push the knob hard against the sleeve. The knob moves approximately 5mm to the sleeve and has to be turned clock -wise by approximately 30 degrees. Now release the knob and it will slip back the same distance. Now the knob is assembled to the targeting sleeve and has to be connected to the target arm (Fig. 39c).
首先将旋钮组装到定位套筒上(图39a)，调整旋钮上的点，使其与定位套筒上的箭头对齐，插入5毫米，顺时针旋转大约30度，将旋钮拧紧。松开旋钮，它就会回到原来的位置。将旋钮装到定位套筒上，连接到定位臂(图39c)。
As an alternative, the speedlock sleeve is newly available and allows for assembly of the sleeve directly to the targeting arm without going through above mentioned step. The speedlock sleeve has the same functions as the assembled targeting sleeve and knob. (Fig. 39d)作为替代方案，快速锁定套筒是将套筒直接组装到定位臂而不经过上述步骤。快速锁定套筒具有与组合的定位套筒和旋钮相同的功能（图39d）。
Assembly of the targeting device and the Gamma3 nail 180组装定位装置和180Gamma3钉The selected Gamma3 nail is now assembled to the carbon fiber target device as shown in Fig. 40. The nail connecting part of the targeting device is designed with an easy assembly fun ction for fast and secure nail fix ation.将选定的Gamma3髓内钉组装到碳纤维的定位装置上，如图40所示。定位装置与髓内钉的连接部分装配简单，可快速安全地固定髓内钉。
Ensure that the locating pegs fit into the corresponding notches of the proximal part of the nail.确保定位栓与髓内钉近端凹槽相配合。Fully tighten the nail holding screw with the ball tip screwdriver, so that it does not loosen during nail insertion.用球形螺丝刀拧紧髓内钉固定螺丝，使其在插入时不会松动。Before starting surgery the following functions of the targeting device have to be checked:术前必须检查定位装置的以下功能：1、Secure fixation between nailand target device.2、Lag screw guide sleeve matchesthe selected nail angle.3、Distal locking position of thetissue protection sleeve, for required “static” or “dynamic” locking.1、髓内钉和定位装置之间的牢固程度。
2、拉力螺钉导筒与选定的钉角（颈干角）是否相匹配。3、远端锁定钉的保护套筒位置，是“静态”还是“动态”。Before checking the function of the lag screw guide sleeve or tissue protection sleeve for the distal locking, the speedlock sleeve knob must be positioned in the counter clockwise position. Pass the lag screw guide sleeve gently through the hole of the speedlock sleeve and tighten it gently in its final position by turning the knob clockwise. Check correct nail angle using the K-wire, 4.2mm drill or lag screw step drill (Fig. 41).在检查拉力螺钉导向套管或组织保护套管的远端锁定功能之前，必须将快速锁定套筒旋钮定位在逆时针位置。将方头螺钉套管轻轻穿过快速锁定套筒的孔，顺时针旋转旋钮，将其拧紧到最终位置。使用克氏针，4.2mm钻头或拉力螺钉杆检查钉角（图41）。
Remove the lag screw guide sleeve in the opposite order; turn the speedlock sleeve knob counter-clockwise and remove the lag screw guide sleeve by pulling it back.按相反顺序拆卸拉力螺钉套筒：逆时针旋转快速锁定套筒旋钮，将拉力螺钉导向套筒拆卸。Before the distal locking function can be checked, the speedlock sleeve has to be positioned in either the “static” or “dynamic” mode.在检查远端锁定功能之前，必须将快速锁定套筒定位在“静态”或“动态”模式。Pull the speedlock sleeve back and turn the sleeve until the required distal locking position is reached. Now push the sleeve against the target arm until a “snap in” is felt.向后拉快速锁定套筒并转动套筒，直至远端锁定位置合适，然后将套筒推向定位臂，直到感觉到“啪”的声响。The distal tissue protection sleeve is passed through the speedlock sleeve until its final position is achieved. Lock the distal tissue protection sleeve by gently turning the speedlock sleeve knob clockwise. Check position with the drill sleeve and 4.2mm drill (Fig. 41a).远端组织保护套管穿过快速锁定套筒到达到合适位置。顺时针轻轻转动快速锁钉套筒旋钮，锁定远端组织保护套。用钻套和4.2mm钻头检查位置（图41a）。
Note: 注意Before starting surgery, the implant and instrument assembly must be checked. Ensure that the sleeve angle matches the corresponding nail angle chosen, e. g. a 125° position in speedlock sleeve for a 125° nail, and the distal sleeve matches either for “dynamic” or “static” locking as required (Fig. 41 and 41a).在开始手术前，必须检查植入体和器械的装配。确保套筒角与所选择的钉角相匹配，例如，125°钉在快速锁定套筒中的125°位置，远端套筒根据需要匹配“动态”或“静态”的锁定(图41和41a)。
