Abstract
The present invention relates to an instrument for the application of material and comprising an elongated unit, a material application member pivotally connceted to the distal end of the elongated unit, so as to allow movement of an applicating member relative to the elongated unit, means for retaining the applicating member in a desired angular positon during surgical intervention. In particular, an instrument according to the invention is suited for the application of surgical sheet repair material. An instrument according to the invention is designed for use in minimally invasive, endoscopic or conventional surgery.
Claims28
An instrument for the application of surgical sheet material and comprising
- an elongated unit,
- a sheet material applicating member pivotally connected to the distal end of an elongated rod member comprised in the elongated unit, so as to allow movement of the applicating member relative to the elongated unit,
- manoeuvring means for the pivotal movement of the applicating member,
- operating means operating the manoeuvring means and being positioned at the proximal end of the elongated unit, the operating means comprising a rotatably mounted adjustment member and being connected to the applicating member through force transmission means comprising:
- a spindle which is mounted rotatably about its longitudinal axis and coextend with the rod member, and which has first threads formed thereon, and
- at least a first longitudinally displaceable member defining second threads engaging with the first threads, the displaceable member being interconnected with the applicating member, whereby rotation of the spindle member causes displacement of the first displaceable member and a pivoting movement of the applicating member around its pivot at the distal end of the elongated unit, and whereby the applicating member may be retained in a desired angular position during surgical intervention.
An instrument for the application of surgical sheet material and comprising
- an elongated unit comprising a shaft with a handle,
- a sheet material applicating member pivotally connected to the distal end of the elongated unit, so as co allow movement of the applicating member relative to the elongated unit,
- means for retaining the applicating member in a desired angular position during surgical intervention,
- a sleeve member having a trumpet-shaped enlargement at its proximal end,
- the interconnection between the elongated unit and the applicating member comprising a contact member, which is movably connected to the elongated unit, and which may pivot at an angle of up to about 135.degree. to each side from its straight position, and which is connected to the elongated unit by means of a tension bolt, the contact member comprising connection means, which are guided through the elongated unit to the upper exterior of the proximal end of the elongated unit,
- the applicating member with a stopping means and a sheet holding means being pivotally connected to the contact member.
An instrument for the application of surgical sheet material and comprising:
- an elongated unit comprising a shaft with a handle,
- a sheet material applicating member pivotally connected to the distal end of the elongated unit, so as to allow movement of the applicating member relative to the elongated unit, the interconnection between the elongated unit and the applicating member comprising a contact member, which may pivot at an angle of up to about 135.degree. to each side from its straight position, the tensile strength of the hinge mechanism being determined by a tension bolt whereby the applicating member may be retained in a desired angular position during surgical intervention, the applicating member comprising a stopping means and a sheet holding means and being rotatably mounted on the contact member.
An instrument for the application of surgical sheet material and comprising
- an elongated member,
- a sheet material applicating member pivotally connected to the distal end of the elongated member,
- wherein the elongated member has at least a first and a second portion, and wherein the second portion is surrounded by a sleeve member, and wherein the interconnection between the elongated member and the applicating member has an extension forming the applicating member, said extension being provided with a slit, the slit being suited for fastening a sheet of surgical material, the applicating member being pivotable at an angle of up to about 90.degree. in any direction, the interconnection between the applicating member and the elongated member comprising a spiral spring.
