    • Embodiments of the present invention provide a middle ear prosthesis that can be adjusted in situ. Embodiments of the invention also relate to a method for adjusting a middle ear prosthesis in situ. In specific embodiments, the middle ear prosthesis can be inserted into the middle ear of a patient during surgery and then, after the surgery, the length of, or distance between the end resting on the malleus and the end resting on the stapes, can be adjusted without the need to touch the prosthesis through a surgical intervention. A middle ear prosthesis can include a first element 1 having a first interconnecting end 3 and a malleus end 9, for resting on a malleus or tympanic membrane, and a second element 5 having a second interconnecting end 7 and a stapes end 11, for resting on a stapes (either capitulum or footplate), where the first and second interconnecting ends interconnect with each other. The first element can incorporate an outer cylinder with an approximately cylindrical head 9, at the malleus end, and the second element can include an inner cylinder with an approximately conical foot 11, acting as the stapes end. When the prosthesis is implanted in a patient, the head 9 of the outer cylinder can rest on the malleus or tympanic membrane and the foot 11 of the inner cylinder can rest on the stapes capitulum or footplate. The inner cylinder can be inserted into the outer cylinder and inhibited from sliding by a clamp 15 with a compliant portion 17. External forces can be applied to the clamp 15 to actuate release of the clamp 15 and allow for adjustment of the length of the prosthesis in situ.
    • 本发明的实施例提供可以原位调节的中耳假体。 本发明的实施例还涉及一种用于原位调整中耳假体的方法。 在具体实施例中,中耳假体可以在手术期间插入到患者的中耳中,然后在手术之后,搁置在踝上的末端或搁置在镫骨上的末端之间的距离或距离可以是 调整而不需要通过外科手术触摸假体。 中耳假体可以包括具有第一互连端3和垂直端9的第一元件1,用于搁置在马蹄形或鼓膜上,第二元件5具有第二互连端7和镫端端11,用于休息 在第一和第二互连端彼此互连的镫骨(头帽或脚板)上。 第一元件可以包括在圆柱形端部具有近似圆柱形头部9的外圆柱体,并且第二元件可以包括具有近似圆锥形的脚11的内圆柱体,其作为镫形端。 当假体植入患者体内时,外筒的头部9可以搁置在锤骨或鼓膜上,并且内筒的脚11可以搁置在镫骨头或脚板上。 内筒可以插入到外筒中并且通过具有柔性部分17的夹具15阻止滑动。外力可以施加到夹具15以致致动夹具15的释放并且允许调节假体的长度 在原地。
