Fig. 2 is the structural representation that this utility model handle unclamps.

Detailed description of the invention

Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail.

Embodiment 1:

See Fig. 1 ~ Fig. 2, the present embodiment comprises fixed handle 2, flexible handle 8, handle resetting means and device for positioning handle, be connected by a spiral pin 11 between fixed handle 2 with flexible handle 8, flexible handle 8 can rotate along a spiral pin 11, and fixed handle 2 is connected with the caliper 1 of surgical grasping forceps.

Described handle resetting means comprises a whirlpool spring 12, holder 9, holder 9 and is fixed on flexible handle 8, and the stiff end 121 of a whirlpool spring 12 snaps in a holder 9 and fixes, and the spiral end 122 of a whirlpool spring 12 is inserted in a spiral pin 11.Hold with a firm grip handle, clamp, clamps for axle rotates with a spiral pin 11 by flexible handle 8, simultaneously tensioner whirlpool spring 12.After completing clamp operation, as long as release handle, under the effect of a whirlpool spring 12, fixed handle 2 and flexible handle 8 unclamp reset automatically, very convenient, without the need to hand-reset.

Described device for positioning handle comprises No. two whirlpool springs 7, No. two holders 3, No. two spiral pins 6, clamp 10, latches 4, No. two spiral pins 6 are fixed on fixed handle 2, latch 4 is inserted in No. two spiral pins 6 and can rotates, and clamp 10 is fixed on flexible handle 8, and clamp 10 and latch 4 match each other; No. two described holders 3 are fixed on fixed handle 2, and the stiff end 71 of No. two whirlpool springs 7 snaps in No. two holders 3 and fixes, and the spiral end 72 of No. two whirlpool springs 7 is inserted in No. two spiral pins 6.Hold with a firm grip handle time, press latch 4, latch 4 rotates, and makes clamp 10 snap in latch 4; Latch 4 rotarily drives No. two whirlpool spring 7 tensioners simultaneously, and the elastic force of No. two whirlpool springs 7 makes clamp 10 and latch 4 clamp and can not loosen, thus by two handle location, caliper 1 is clamped firmly, can not loosen.

In the present embodiment, clamp 10 is provided with button 5, button 5 is positioned at the front end of fixed handle 2.Button press 5 just can promote latch 4, convenient operation.
