Abstract

Un aparato de fijación quirúrgica, comprendiendo: un conjunto de mango (12) adaptado para accionar dicho aparato de fijación quirúrgica; una porción de cuerpo central (14) extendiéndose desde el conjunto de mango; y una porción de cabeza distal (16) incluyendo un conjunto de envuelta (27) y un conjunto de yunque (30), incluyendo el conjunto de yunque: un conjunto de cabeza de yunque (40) incluyendo una cabeza de yunque (42) definiendo un rebajo interior (42a) soportando una placa de activación (48) que tiene al menos una orejeta (48e), un miembro deformable (46) situado distalmente de la placa de activación, y un anillo de fijación (50) situado proximalmente a la placa de activación y adaptado para fijar la placa de activación; y un conjunto de vástago central de yunque (60) comprendiendo un vástago central de yunque (62) definiendo un eje longitudinal (A) y estando conectado giratoriamente al conjunto de cabeza de yunque alrededor de un eje de giro (B) e incluyendo un émbolo (64) y un resorte de émbolo (66) en comunicación mecánica con la cabeza de yunque (42), estando el émbolo configurado para entrar en contacto con el conjunto de cabeza de yunque después de una actuación del aparato de fijación quirúrgica, definiendo el conjunto de vástago central de yunque un relieve configurado para inhibir la cabeza de yunque (42) contra el giro alrededor del eje (B), estando configurado el relieve para ser aplicado a la orejeta (48e) de la placa de activación; en donde, después de la actuación del aparato de fijación quirúrgica, el miembro deformable (46) está configurado para deformarse de manera que la placa de activación (48) es hecha avanzar distalmente dentro del rebajo interior (42a) y desaplica la orejeta de la placa de activación del relieve del vástago central de yunque (62) para que la cabeza de yunque (42) esté libre para girar alrededor del eje de giro (B) bajo la precarga del émbolo (64) y el resorte de émbolo (66), caracterizado por que el conjunto de cabeza de yunque incluye un poste (44) que se extiende proximalmente desde la cabeza de yunque (42), incluyendo el poste un diente (44f) para ser aplicado al conjunto de vástago central de yunque, comprendiendo además un manguito (68) dispuesto deslizablemente a lo largo de una superficie exterior del vástago de yunque (62), teniendo el manguito una abertura (68b) en donde en una posición no activada, el manguito está dispuesto alrededor de una porción distal (62d) del vástago central de yunque para que el diente (44f) sobresalga a través de la abertura (68b), estando configurado dicho manguito para aplicar y mover el tejido durante la actuación del aparato de fijación quirúrgica en donde el giro de la cabeza de yunque alrededor del eje de giro (B) desaplica el diente (44f) de la abertura (68b) y la cabeza de yunque es aplicada y mueve el manguito proximalmente a lo largo del vástago central de yunque, moviendo proximalmente de esta manera el tejido dispuesto sobre él para separar el tejido del eje de giro (B) durante la inclinación de la cabeza de yunque (42).
