The perforation instrument in order arranges opening of cylindrical or opposite taper condition in the pliability material and to cut off

摘要

(57) Abstract This invention forms opening in pliability material, such as skin of the patient the surface and the based plate which possesses the underside which opposes (36) includes, the surface of the skin deformation contour where the surface projects at least to one upward direction (56) it is the perforation instrument in order to possess. As for the based plate, to the pocket which is prepared surgically while organizing the patient, you remove and you have reached the point where it inserts in possible state. You install the instrument, in the surface of the based plate, the petiole material which from here projects to upward direction (12) you can include. The clamping member (100), with the relationship which is piled up with the surface of the based plate, is connected to the perforation instrument. The clamping member deformation tightens the pliability material unrestrictedly with the surface and the clamping member of the based plate, makes the engagement which is put easy. When the based plate is inserted in the pocket of organization, the skin of the patient engages between the based plate and the clamping member. The perforation instrument includes the cutter position for the petiole material. The cutter, being operation possible vis-a-vis the clamping member, in order to form opening which possesses the cylindrical wall or the wall of opposite taper condition in the pliability material, deformation unrestrictedly are engaged the pliability material and it cuts off engages with the clamping member.
