Abstract
The utility model discloses an orthodontic arch wire ligator, including claw beam, screw thread handle, forceps holder, the forceps holder is the conical body of three cross -section fan -shaped, and three cross -section fan -shaped conical body is circumference equipartition elastic connection, naturally, under the non - stress, has the clearance between the three cross -section fan -shaped conical body of circumference equipartition, forceps holder lower extreme fastening connection is on the claw beam, claw beam and screw thread handle lower part threaded connection, screw thread handle upper portion has the bell mouth, the three cross -section fan -shaped conical body and the screw thread handle upper portion bell mouth of forceps holder cooperate, during operating condition, the forceps holder is inserted at the arch wire both ends, and the screw thread handle descends along the downward spiral of claw beam, and the ascending clearance elimination gripping bow silk of bell mouth on screw thread handle upper portion is followed to the three cross -section fan -shaped conical body of forceps holder, during unoperated state, screw thread handle along the claw beam spiral shell screwing in liter that makes progress, the three cross -section fan -shaped conical body of forceps holder has the bell mouth lax initial state of recovering that descends, the separation of three cross -section fan -shaped conical body clearance along screw thread handle upper portion. The utility model discloses arch wire slippage phenomenon can not take place during the use.
Description
Technical field
This utility model belongs to technical field of medical instruments, is related to a kind of orthodontic arch filament ligature carrier, for oral cavity just
The colligation operation of arch wire when abnormal.
Background technology
In daily orthodontic treatment, the arch wire ligation apparatus that doctor is used are typically needle holder, based on needle holder
Feature, uses and inconvenient；Because needle holder is not closely sealed or catabiosis may occur in which that blade slips or handle flicks, make
Become to ligature unsuccessfully, or even bracket comes off, extend chair other operating time, relatively low work efficiency；And arch wire end cut off not in time
Patient or doctor may be stabbed, thus bringing unnecessary worry to treatment.
Existing ligature forcepss can not improve this drawback, complex operation well, does not play mesh simple and easy to operate
's.
Content of the invention
The utility model discloses a kind of orthodontic arch filament ligature carrier, to solve to use not side in prior art
Just, needle holder is not closely sealed occurs that blade slips or handle flicks, arch wire end is cut off not in time and is possible to stab with catabiosis
The problems such as patient or doctor.
This utility model includes claw beam, thread handle, clamp；Clamp is the bullet of three section fan-shapeds, three sections
Fan-shaped bullet circumferentially uniform elastic connection；Under natural force-free state, between three section fan-shaped bullets of circumference uniform distribution
There is gap；Clamp lower end is fastenedly connected on claw beam；Claw beam is connected with thread handle lower thread；Thread handle top has
Bellmouth；Three section fan-shaped bullets of clamp are matched with thread handle upper taper hole；During working condition, arch wire two ends
Insertion clamp, rotates thread handle, and thread handle declines along the downward spiral of claw beam, and three section fan-shaped bullets of clamp are along spiral shell
The bellmouth of stricture of vagina handle upper portion rises, and three section fan-shaped bullet constringency clefts of clamp eliminate, three section fans of clamp
Shape bullet stretches out tightens up clamping arch wire；During off working state, rotate thread handle, thread handle is along along claw beam upwards spiral
Rise, threadingly handle upper portion has bellmouth decline, three section fan-shapeds cones of clamp to three section fan-shaped bullets of clamp
Body relaxes and recovers initial condition, and three section fan-shaped cone clearance separate.
Of the present utility model have the active effect that pincers beak clamping is firm strong, arch wire is without preforming；Will to arch wire length
Ask relatively low, can material-saving；The screw thread of handle portion, can increase frictional force, during ligation, be not in that arch wire slips；Knot
Uniformly no arch wire fractures bundle dynamics；And arch wire end is accommodated in ligature carrier, patient or doctor will not be pricked, overall raising ligatures
Quality, the other work efficiency of lifting chair.
Brief description
Fig. 1 is this utility model structural representation；
Fig. 2 is utility model works state sectional view；
Fig. 3 is utility model works state a-a profile；
Fig. 4 is this utility model off working state sectional view；
In figure: 1 claw beam, 2 thread handles, 3 clamps, 4 arch wires.
Specific embodiment
Describe an embodiment of the present utility model below in conjunction with accompanying drawing in detail.
This utility model embodiment as shown in Figure 1, Figure 2, Figure 3 shows, including claw beam 1, thread handle 2, clamp 3；Clamp 3 is three
The bullet of individual section fan-shaped, three section fan-shaped bullet circumferentially uniform elastic connections；Under natural force-free state, circumference
Between three uniform section fan-shaped bullets, there is gap；Clamp 3 lower end is fastenedly connected on claw beam 1；Claw beam 1 and thread handle
2 lower thread connect；Thread handle 2 top has bellmouth；On three section fan-shaped bullets of clamp 3 and thread handle 2
Portion's bellmouth matches.
As shown in Figure 2 and Figure 3, during working condition, clamp is inserted at arch wire 4 two ends, rotates thread handle 2, thread handle 2 edge
The downward spiral of claw beam 1 declines, and the bellmouth on three section fan-shaped bullets of clamp 3 threadingly handle 2 top rises, clamp 3
Three section fan-shaped bullet constringency clefts eliminate, three section fan-shaped bullets of clamp 3 stretch out tightens up clamping arch wire 4；
Carry out correction ligation bracket process, after the completion of ligation, arch wire 4 cut off by cooperation shears, and the broken ends of fractured bone stays ligature forcepss after arch wire 4 clamping
In.
As shown in figure 4, during off working state, rotating thread handle 2, thread handle 2, along claw beam 1 spiral upwards, clamps
Threadingly handle 2 top has bellmouth decline, three section fan-shaped tapers of clamp 3 to three section fan-shaped bullets of folder 3
Body relaxes and recovers initial condition, and three section fan-shaped cone clearance separate, and discard the broken ends of fractured bone.
