Abstract

The utility model discloses a kind of be adjusted and holds reduction pincers, including upper and lower caliper, caliper is connected by hinge joint with jaw front, plier then passes through screw and connect with baffle, gasket is equipped between plier and baffle, the gasket is matched with baffle, has two stringer sliding slots corresponding with plier screwhole position in the middle part of baffle.The position that baffle needs to adjust should be first determined before resetting according to the broadband of quasi- implant plate, gradually upper and lower caliper is closed up in pressurization in reseting procedure, and it maintains position, caliper not to be influenced the progress of interior fixed operation to side bending after reset satisfaction by upper and lower caliper occlusion rack gear.

Description

It is adjustable to hold reduction pincers

Technical field

The utility model relates to fix medical apparatus in orthopaedics, more particularly to a kind of adjustable reduction of holding clamps.

Background technique

Resetting and being fixed temporarily in fracture operation is an extremely critical step, the time longest usually expended in this step, Particularly with comminuted fracture and a most intractable step, if ideal reset can be realized as early as possible, operating time will contract significantly Short, surgical effect also will be more satisfied with.

Currently, existing fracture resetting tongs have a single function, reset effect is not satisfactory, it is crucial that cannot be same after resetting When plate fix, and the reduction forceps that be able to achieve reset while can be fixed there is no practical application product, application publication number It is disclosed a kind of " unobstructed fracture resetting tongs " for the Chinese invention patent of 105011992 A of CN, the patent is relatively reasonable more real Show the fixation simultaneously in the reduction of the fracture, but the patent is only applicable to Fracture Simple, and be easy to be stopped when steel plate screwing, There are still certain defects.

Utility model content

In order to overcome existing fracture resetting tongs to reset low efficiency, can not achieve design defect immediately fixed after resetting, this Utility model provides a kind of " adjustable reduction of holding clamps ", and the baffle of different model, and baffle can be fixed and be replaced to plier Front-rear position can be adjusted as needed, realize the reduction of the fracture by resetting the mutual extrusion of baffle up and down and is fixed temporarily, together Shi Liuyou sufficient space can realize the fixation of steel plate, can not influence to operate by caliper or so bending after reset.

In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is: one kind is adjustable to hold reduction pincers, Including upper and lower caliper, upper and lower caliper is riveted by pin, and caliper is connected by hinge joint with jaw front, jaw front and Plier is linked together, and plier is flat, there is plier screw hole on plier, and plier then passes through screw and connect with baffle, has two in the middle part of baffle Stringer groove is corresponding with plier screwhole position, there is a gasket between baffle and plier.

Its back segment of upper and lower caliper inside can be mutually twisted after respectively having an occlusion rack gear, the two to draw close.

The plier is a cuboid, and corner location respectively has a plier screw hole, and plier screw hole has internal thread.

The baffle design has different size and radian, and each baffle has a matched gasket.

The gasket has common trait: its size is identical as plier, and the gasket back side is plane, and the outside of belly has radian, The radian is consistent with baffle back side radian, and also respectively there are a gasket screw hole, gasket screwhole position and plier screwhole position in gasket quadrangle Identical, gasket screw hole does not have internal thread.

Its outside of belly of the baffle has the tapered protrusion of given amount, two its width of stringer sliding slot in the middle part of baffle with The plier screw hole of plier lateral position is equidistant.

Compared with prior art, the utility model has the beneficial effects that firstly, can be clamped compared with conventional reset using baffle is resetted The contact area with bone is greatly increased, Rapid reset is conducive to；Secondly, different model can be selected according to the bone of different thicknesses Baffle has better suitability；Furthermore the position-adjustable of baffle can determine that baffle can according to the steel plate width of quasi- selection The maximum region of adjusting is suitable for the steel plate of different model in this way；In addition, reduction forceps can be locked gradually, be conducive to reseting procedure In continuous adjustment；Finally, after the completion of resetting the progress of interior fixed operation can not be influenced by upper lower clamp to side bending.

The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment

The utility model is described in further detail With reference to embodiment.

As shown in Figure 1 to 4, the adjustable reduction pincers of holding of one kind of the utility model include upper and lower caliper, upper and lower to clamp Body is riveted by pin, and caliper is connected by hinge joint with jaw front, and plier then passes through screw and connect with baffle (according to bone The baffle of bone size selection different model), gasket is equipped between plier and baffle, which matches with baffle, in baffle Portion then has two stringer sliding slots corresponding with plier screwhole position, is fixed baffle with plier with four pieces of screws, answers before resetting The position that baffle needs to adjust first is determined according to the broadband of quasi- implant plate, is gradually pressurizeed in reseting procedure and is closed up upper and lower pincers Body, and position is maintained by upper and lower caliper occlusion rack gear, by caliper to side bending after reset satisfaction, do not influence interior fixed behaviour The progress of work.

Above-described embodiment only is used to further illustrate a kind of orthopaedics loop fasteners of the utility model, but the utility model It is not limited to embodiment, any simple modification made by the above technical examples according to the technical essence of the present invention, Equivalent variations and modification, each fall within the protection scope of technical solutions of the utility model.
