Description

Cardinal ligament forceps

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of cardinal ligament forceps.

Background technology

Cardinal ligament forceps is a kind of medical apparatus and instruments commonly used in the operation, and the clamp cardinal ligament of uterus is used when being mainly used in gynecilogical operation.

Present existing cardinal ligament forceps comprises pincers handle of being made up of upper plier handle and lower plier handle and the binding clip of being made up of upper grip head and lower pliers head; The afterbody and the lower plier handle of upper grip head are fixedly linked; The afterbody and the upper plier handle of lower pliers head are fixedly linked, and upper plier handle and lower plier handle are rotatedly connected; Be provided with sealed tooth on the upper plier handle, be provided with on the lower plier handle with on the following sealed tooth that matches of sealed tooth; At the inner surface of upper grip head and the inner surface of lower pliers head intermeshing horizontal serration is set; Upper grip head and lower pliers head be shape linearly all.Cardinal ligament of uterus toughness is strong, and because the particularity of uterus structure, and in actual use, the cardinal ligament forceps of said structure is easy to slippage from the cardinal ligament of uterus, causes can't carrying out smoothly of subsequent procedures.

Summary of the invention

The technical problem that this utility model will solve provides the cardinal ligament forceps that a kind of effectively clamp is lived cardinal ligament of uterus.

In order to solve the problems of the technologies described above; This utility model provides a kind of cardinal ligament forceps; Comprise pincers handle of forming by upper plier handle and lower plier handle and the binding clip of forming by upper grip head and lower pliers head; The afterbody and the lower plier handle of upper grip head are fixedly linked, and the afterbody and the upper plier handle of lower pliers head are fixedly linked, and upper plier handle and lower plier handle are rotatedly connected; Be provided with sealed tooth on the upper plier handle, be provided with on the lower plier handle with on the following sealed tooth that matches of sealed tooth; Upper grip head and lower pliers head all are the arcuation of deflection upper plier handle axial line the same side; Inner surface at upper grip head is provided with horizontal bastard on 1, goes up the centre distance upper grip head head 8～12mm of horizontal bastard; The upper grip head inner surface from the supreme horizontal bastard of upper grip head head laterally serration is set on the front portion, the upper grip head inner surface from laterally bastard to upper grip head afterbody laterally serration is set on the rear portion; The inner surface of lower pliers head be provided with 1 with on the horizontal following horizontal bastard that is meshed of bastard; The inner surface of lower pliers head also be respectively equipped with anterior under horizontal serration under horizontal serration and the rear portion; Anterior horizontal serration down horizontal serration and is meshed with anterior, under the rear portion on horizontal serration and the rear portion horizontal serration be meshed.

Improvement as the cardinal ligament forceps of this utility model: the tooth depth of horizontal serration equals on the rear portion the laterally tooth depth of serration on the front portion, the tooth depth that goes up horizontal bastard be anterior 2～3 times of horizontal serration tooth depth.

The cardinal ligament forceps of this utility model is because upper grip head and lower pliers head all are the arcuation of deflection upper plier handle axial line the same side; During therefore actual the use, under the prerequisite of the equal entering uterus degree of depth, can effectively increase the contact area of binding clip and cardinal ligament of uterus, thereby guarantee effective clamp cardinal ligament of uterus; And since the binding clip place also be provided with intermeshing on laterally bastard and horizontal bastard down, its deep teeth groove can further guarantee the effective clamp to cardinal ligament of uterus, thereby can effectively avoid cardinal ligament forceps slippage from the cardinal ligament of uterus.

The specific embodiment

Fig. 1～Fig. 4 combines to have provided a kind of cardinal ligament forceps; Comprise pincers handle of forming by upper plier handle 4 and lower plier handle 5 and the binding clip of forming by upper grip head 1 and lower pliers head 2; The afterbody of upper grip head 1 and lower plier handle 5 are fixedly linked; The afterbody of lower pliers head 2 and upper plier handle 4 are fixedly linked, and upper plier handle 4 is rotatedly connected through pincers arbor pin 3 with lower plier handle 5.Be provided with sealed tooth 6 on the upper plier handle 4, be provided with on the lower plier handle 5 with on the following sealed tooth 7 that matches of sealed tooth 6.The all same prior art of said structure, the also same prior art of its method for using.

Upper grip head 1 all is the arcuation of being partial to upper plier handle 4 axial lines (being lower plier handle 5 axial lines) the same side with lower pliers head 2; Inner surface at upper grip head 1 is provided with horizontal bastard 12 on 1, goes up the centre distance upper grip head 1 head 8～12mm of horizontal bastard 12; Upper grip head 1 inner surface from the supreme horizontal bastard 12 of upper grip head 1 head laterally serration 11 is set on the front portion, upper grip head 1 inner surface from laterally bastard 12 to upper grip head 1 afterbody laterally serration 13 is set on the rear portion; That is, go up horizontal bastard 12 and be clamped in anterior going up on horizontal serration 11 and the rear portion laterally between the serration 13.

The inner surface of lower pliers head 2 be provided with 1 with on the horizontal following horizontal bastard 22 that is meshed of bastard 12; Also be respectively equipped with horizontal serration 23 under anterior down horizontal serration 21 and the rear portion at the inner surface of lower pliers head 2; Anterior horizontal serration 21 down horizontal serration 11 and is meshed with anterior, under the rear portion on horizontal serration 23 and the rear portion horizontal serration 13 be meshed.Promptly; Horizontal serration 21 under being provided with from lower pliers head 2 heads to following horizontal bastard 22 of lower pliers head 2 inner surfacies is anterior; Lower pliers head 2 inner surfacies from following horizontal bastard 22 to lower pliers head 2 afterbodys horizontal serration 23 under the rear portion is set, following horizontal bastard 22 is clamped under anterior horizontal serration 21 down and the rear portion between the horizontal serration 23.

The tooth depth of horizontal serration 11 equals the tooth depth of horizontal serration 13 on the rear portion on the front portion, and the tooth depth that goes up horizontal bastard 12 is anterior 2～3 times of horizontal serration 11 tooth depths.

Suitably tilt earlier during the actual use of cardinal ligament forceps, thereby make the binding clip of forming by upper grip head 1 and lower pliers head 2 can get into intrauterine smoothly; Open relatively with lower pliers head 2 through upper plier handle 4 and lower plier handle 5 control upper grip heaies 1 then; Make cardinal ligament of uterus between upper grip head 1 and lower pliers head 2; It is closed relatively with lower pliers head 2 to control upper grip head 1 again, utilize can intermeshingly horizontal bastard 12 and down horizontal bastard 22, front portion go up horizontal serration 11 and anterior under on the horizontal serration 21, rear portion under horizontal serration 13 and the rear portion horizontal serration 23 tightly vise cardinal ligament of uterus; Last sealed tooth 6 that cooperatively interacts and following sealed tooth 7 can guarantee to lock the relative position relation between upper grip head 1 and the lower pliers head 2.

At last, it is also to be noted that what more than enumerate only is a specific embodiment of this utility model.Obviously, this utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of this utility model all should be thought the protection domain of this utility model.
