Abstract
The utility model relates to a pair of pincers for fetching materials in the uterine cavity, which is mainly used for hysteroscopic operation and belongs to the technical field of medical instruments. The pincers comprise two handles, two pincers rods and two pincer clips, wherein one ends of the pincers rod are fixed with the handles, and the other ends are fixed with the pincers clips, and the three are welded into a whole; lock teeth are arranged on the two handles and are matched with each other, and the lock teeth are clamped and fixed with each other when the handles are clamped; the two pincers rods are connected by connecting bolts, and the connecting bolts are positioned at one ends of the pincers rods, close to the pincers clips; the two pincers clips are provided with clamp teeth which are matched with each other; and oval grooves are arranged on the pincers clips, and the edges of which adopt a circular arc structure. With the pincers, the structural design is reasonable, the size of the pincers clips is very suitable for that of the uterine cavity, simultaneously the uterine cavity can not be damaged due to the circular arc structural design, the myoma or the polyp tissue is convenient to grip due to the design of the clamp teeth and the oval grooves, thus being extremely convenient.
Description
Technical field
This utility model relates to a kind of uterine cavity and gets the thing pincers, and it is mainly used in hysteroscope operation, belongs to the medical device technology mechanical field.
Background technology
In the gynecological clinic medical operating, the healthcare givers needs cut muscular tumor or polyp tissue are taken out uterine cavity after downcutting hysteromyoma or inner membrance polyp.Prior art generally is with ovum circle nipper and ring-removing forceps, and the defective of ovum circle nipper is that ovum circle nipper vice body is long, and entering uterine cavity, to open amplitude too small, binding clip is thick, difficulty or ease enter human body cervix uteri mouth, if enter human body palace mouth, cause the damage of perforation and uterine cavity inner surface cell membrane easily; Though the ring-removing forceps binding clip is little, binding clip is very sharp, enters uterine cavity, easily causes the perforation of uterus even intestinal perforation, and vice body can't lock, and is unfavorable for grasping carrying out smoothly of operation, does not satisfy ideal surgical effect.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, and the uterine cavity that is exclusively used in hysteroscope operation is got the thing pincers.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of uterine cavity is got the thing pincers, comprise handle, claw beam and clamp, handle, claw beam and clamp all have two, one end and the handle of claw beam are fixed, the other end and clamp are fixed, it is characterized in that: be provided with the lock tooth on described two handles, and match each other; Two claw beams connect by connecting bolt; All have the folder tooth on two clamps, the folder tooth matches each other; Clamp is provided with oval groove.
Connecting bolt described in the utility model is positioned at an end of close clamp on the claw beam.
The edge of clamp described in the utility model adopts arc-shaped structure.
Handle described in the utility model, claw beam and clamp are integrally welded.
The vertical distance of connecting bolt described in the utility model and clamp is 4-6cm.
This utility model compared with prior art has following positive effect: reasonable in design, and the size of clamp is highly suitable for uterine cavity, and the structural design of circular arc can not cause damage to uterine cavity simultaneously; The design of folder tooth and oval groove is convenient to be grasped muscular tumor or polyp tissue, very convenient.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is the plan structure sketch map of clamp part among Fig. 1.
Among the figure: 1 handle, 2 claw beams, 3 clamps, 4 lock teeth, 5 connecting bolts, 6 folder teeth, 7 oval grooves.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1-2, present embodiment mainly is made up of handle 1, claw beam 2 and clamp 3, and handle 1, claw beam 2 and clamp 3 all have two, and an end of claw beam 2 and handle 1 are fixing, and the other end and clamp 3 are fixing, and the three is integrally welded; Be provided with lock tooth 4 on two handles 1, and match each other, lock tooth 4 mutual clampings and fixing when handle 1 clamps; Two claw beams 2 connect by connecting bolt 5, and connecting bolt 5 is positioned at an end of close clamp 3 on the claw beam 2, and connecting bolt 5 is 5cm apart from clamp 3 vertical distances; All have folder tooth 6 on two clamps 3, folder tooth 6 matches each other; Clamp 3 is provided with oval groove 7, and the edge of clamp 3 adopts arc-shaped structure.
During use, clamp 3 enters uterine cavity muscular tumor or polyp tissue is carried out gripping, because connecting bolt 5 is positioned on the claw beam 2 end near clamp 3, makes clamp 3 enter folding fully behind the uterine cavity; Clamp 3 edges adopt arc-shaped structure in addition, can not be damaged to uterine cavity when therefore opening with closure in uterine cavity; When interior muscular tumor of clamp 3 gripping uterine cavities or polyp tissue, be difficult for slippage under the effect of folder tooth 6, oval groove 7 is more firm when clamp 3 is clamped, and muscular tumor or polyp tissue can be stuck in the oval groove 7; After clamp 3 was clamped muscular tumor or polyp tissue, joystick 1 made handle 1 keep the state that clamps the 4 mutual clampings of the lock tooth on the handle 1, clamp 3 can lock, and can arbitrarily not unclamp the carrying out of convenient operation, even doctor's release handle 1, clamp 3 still can keep locking.
In addition, need to prove, specific embodiment described in this description, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of this utility model patent according to this utility model patent.
