【技术实现步骤摘要】
一种上翘咬骨钳
本技术涉及医疗器械领域,尤其涉及一种上翘咬骨钳。
技术介绍
咬骨钳是一种神经外科,骨科常用的手术器械,多被用于脊柱手术中的咬骨。传统的咬骨钳可替换性差,一旦某一部分发生损坏需要进行整体更换,造成了资源的大量浪费。钳头多是固定住的,适应性窄。
技术实现思路
本技术针对现有技术的不足,提供一种上翘咬骨钳。本技术通过以下技术手段实现解决上述技术问题的:一种上翘咬骨钳,包括:固定手柄、活动手柄、外钳体、内钳体、推杆、杆套、杆体、上钳头和下钳头;所述固定手柄和活动手柄铰接;外钳体连接在固定手柄上,所述外钳体内设有空腔,并开设有与所述空腔连通的通孔;所述活动手柄一端通过所述通孔伸入所述空腔内;所述内钳体套装在外钳体背离活动手柄一侧,所述内钳体内滑动连接有推杆,所述推杆一端位于所述内钳体内,另一端与所述活动手柄相抵,所述推杆与内钳体之间连接有复位弹簧;所述杆套套装在内钳体背离外钳体一侧;所述杆体一端连接在推杆上,另一端依次穿出内杆体和杆套与所述上钳头连接;所述下钳头连接在所述杆套背离内钳体一侧,其与上钳头之间相互配合形成咬口。使用时,捏住活动手柄,活动手柄逐渐靠近固定手柄时,活动手柄一端抵住推杆,推杆沿内钳体进行滑动,并带动上钳头逐渐靠近下钳头,上钳头和下钳头相互配合以实现咬骨操作。咬骨完毕,松手,复位弹簧带动上钳头复位。进一步地,所述上钳头和下钳头的切口相互平行,并与水平面之间具有倾角。进一步地,所述下钳头的切口与水平面之间的夹角为α°,120≤α≤135°。进一步地,所述固定手柄中部向外垂直延伸形成有挡板。进一步地,所述上钳头一侧具有上斜面,所述下钳头一侧具 ...
