Description of drawings
In the accompanying drawings, for example in unique Fig. 1, the present invention has been shown, an axial cutaway view of its expression surgical forceps of the present invention.
The specific embodiment
Accompanying drawing is expressed the surgical forceps 1 that has a tubular handle 2, and a grip finger 3 with two movable branching portions 4,5 is set on its distal end, and branching portion supports around axis 6 pivotally.
The connecting rod 7 that passes shank acts on the grip finger 3, and along shank 2 lengthwise movements the time, branching portion 4,5 is relatively rotated with respect to each other.When connecting rod 7 is pulled back along arrow 8 directions are past, branching portion 4,5 is applied a closing force, make their closures, until the position of complete closure.
On the stub area in clamp 1 near, be provided with the two poles of the earth plug 9, on it, can connect unshowned conduction connection cord, so that plug is connected with a high frequency electric source.Two conduction connecting lines 10,11 pass shank 2 one through to grip finger 3 in clamp inside from plug 9; And there with branching portion 4,5 acting surfaces on unshowned electrode be connected; So that carry high frequency voltage, thereby clamping when organizing at branching portion 4, coming heat tissue through electric current between 5 to them.
Jaw 3 can take off from shank 2 by unshowned method, and is for example fixing through bayonet coupling or the like.
Shank 2 has the protecting cover 12 of the nearly split shed that a tubulose enlarges on its nearly middle-end, it reaches a head 13 always, and this head is fixed on of handle 15 on the shank handle member 14 of shank 2.One connecting rod handle member 16 of handle 15 is connected with shank handle member 14 through a hinge 17 pivotally, and removably is connected on the single-revolution hinge 18 through the spheric termination of making of connecting rod 7., usefulness can handle the jaw of clamp 3 when holding in hand with operating handle 15.
In order to operate, connecting rod 7 must relatively move with shank 2 each other.That is the head 13 of shank handle 14 must be connected with shank 2.The sleeve 21 that end piece 20 that surrounded by helical spring 19, through in far away is fixed on the shank 2 is used for this connection.
Sleeve 21 surrounds connecting rod 7 and can be bearing in slidably vertically in the head 13 of shank handle 14, and with an outward flange 22 it is fixed with respect to the shank handle, prevents in the distance, to extract on the direction.
