Detailed Description

As shown in figure 1, the utility model is a structural schematic diagram of the utility model, a pair of ENT surgery forceps comprises a forceps handle 1, a front sleeve 2 is arranged at the front end of the forceps handle 1, the front end of the front sleeve 2 is pivoted with a rear sleeve 3, a forceps head pull rod 4 is arranged in the front sleeve 2 and the rear sleeve 3, one end of the forceps head pull rod 4 is connected with the forceps handle 1 and the other end is connected with a forceps head 5, a fixed block 6 is welded on the rear sleeve 3, one end of an upper extension spring 7 is fixedly connected with the fixed block 6 and one end of a lower extension spring 8 are simultaneously connected with one end of the lower extension spring 8, the other end of the upper extension spring 7 and the other end of the lower extension spring 8 are respectively connected with an upper adjusting pull rod 9 and a lower adjusting pull rod 10, the upper extension spring 7, the lower extension spring 8, the upper adjusting pull rod 9 and the lower adjusting pull rod 10 are respectively arranged in an upper through hole 11 and a lower through hole 12 which are arranged on the front sleeve 2, the forceps head, one end of the spring 14 is fixed on the wall of the central groove 13, the other end of the spring is fixed on the binding clip pull rod 4, and the front ends of the upper adjusting pull rod 9 and the lower adjusting pull rod 10 are respectively fixed with an upper pull adjusting handle 15 and a lower pull adjusting handle 16. The spring 14 plays a role in positioning the binding clip pull rod 4, and simultaneously plays a role in recovering the binding clip to be loosened after the binding clip 5 is pulled and locked by the binding clip handle 1. The binding clip pull rod 4 is supported by the steel wire, so that the binding clip 5 can be loosened and tightened, and meanwhile, the binding clip can also be bent when the rear sleeve 3 rotates by an angle without influencing the normal use of the binding clip pull rod 4.

As shown in fig. 1 to 3, the binding clip 4 is inserted into a central groove 13 formed in the front sleeve 2 and the rear sleeve 3. Go up adjusting link 9 and the welding of adjusting link 10 down and have stopper 17, go up adjusting link 9 and the welding of adjusting link 10 down and have the fixture block 18 that is used for preventing to go up expanding spring 7 and lower expanding spring 8 resilience, go up expanding spring 7 and lower expanding spring 8 and take-up the location to back sleeve pipe 3, guaranteed that preceding sleeve pipe 2 and back sleeve pipe 3 are in coaxially. The upper extension spring 7 and the lower extension spring 8 are consistent in length and elasticity and are respectively fixed on the two sides of the front sleeve 2 and the rear sleeve 3, so that the two sides of the rear sleeve 3 are stressed uniformly.

During the use, the pulling of tong handle 1 controls tong head pull rod 4 and then control lax and the clamp tightly of tong head 5, adjust pull rod 9 and pull-up regulation handle 15 and pull-down regulation handle 16 on the pull rod 10 down through the pulling, thereby it drives the rotatory angle that changes back sleeve pipe 3 of back sleeve pipe 3 to change the elasticity of expanding spring 7 and lower expanding spring 8, play the problem of adjusting tong head 5 angle like this, this operation pincers can be according to the operation demand, the direction is adjusted at any time, both the operation of operative employee of being convenient for, can save the operation time again, also can reduce the chance that the produced mistake of frequent change apparatus injures surrounding tissue.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
