Abstract: The invention relates to a surgical cutting instrument (1), in particular an obstetric cutting instrument for performing an episiotomy. The cutting instrument comprises a blade-holder (4) with a lip (5) connected thereto, an accommodation area for a skin fold being formed between the blade-holder (4) and the lip (5). Prior to use, the blade (6) is retracted in the blade-holder (4). By operation of, for example, a push arm (8), a cutting edge (11) can be placed against the inside of the bottom lip (5). The cutting instrument has a substantially V-shaped external periphery, so that the instrument can be accommodated comfortably between the thumb, index finger and middle finger. The cutting instrument according to the invention permits simple, one-handed operation, with the result that an accurately formed, straight incision can be obtained, with disturbing cutting noises being reduced. The cutting instrument can be used either with the left hand or with the right hand, making it possible for the cutting to be either in the left-hand direction or in the right-hand direction as desired. Furthermore, the device is very safe in use, since it does not have any sharp parts, and the cutting edge of the blade is accommodated in the blade-holder.

Filed: 2001-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a fluidized bed furnace or a cyclone to prevent an iron plate from being heated to red heat through large scale blow-by of gas. SOLUTION: Since a furnace wall 1 of a furnace body part 20 where a bed material is present in high density and a high pressure difference occurs is provided with a lattice-form partition plate 11, even when crack occurs to a fire resisting castable material and a heat insulation castable material, of which the furnace wall 1 consists, due to deterioration with time, enlargement of the crack is blocked and no crack grows to a long one exceeding the size of the lattice of the partition plate 11. Thereby, since a crack long enough to allow the occurrence of large scale blow-by of high temperature combustion gas does not occur, the shell of the outer wall of the furnace wall 1 is prevented from being heated to red heat.
