Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of combination type Wicresoft fracture setting device.
Background technology
Good pelvis fracture operation therapeutic effect depends primarily on the accurate reset to fracture in art.Due to pelvis anatomical position complexity, bony structures is irregular, and type of injuries difference can cause dissimilar displacement fracture, and has the muscle of a large amount of different directions to adhere to around pelvis, and anatomical reduction is difficult to obtain completely, particularly the displacement of old fracture.Present fracture of pelvis reduction instrument is very limited, and currently used fracture of pelvis reset pliers is more roomy, there is no again fixed function, therefore needs one to reset flexibly, can fix again the apparatus of fracture.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of simple operation is flexible, operation wound is little, in resetting, can provides pressurization, and the combination type Wicresoft fracture setting device of sclerite fixation can be provided.
The technical scheme in the invention for solving the above technical problem is: this device comprises reset arm, its construction features is also to comprise hollow sliding bar, guide holder, fixed handle and flexible handle, hollow sliding bar is slidably inserted in guide holder, reset arm comprises base and grab, base is provided with circular slide opening, reset arm is slidably inserted on hollow sliding bar by slide opening, and flexible handle is fixedly connected with guide holder, and flexible handle is flexibly connected with guide holder.
On the outer wall of hollow sliding bar described in the utility model, be provided with two symmetrical chutes, guide holder is provided with the draw-in groove that matches and be slidably matched with chute shape at movable hand pommel.
The base of reset arm described in the utility model is provided with unlock button, and unlock button coordinates with the chute positioning and locking on hollow sliding bar.
Guide holder described in the utility model is provided with toggle switch at fixed handle end.
Reset arm described in the utility model also comprises fixing pressurizing block, and grab is connected with base by fixing pressurizing block.
This utility model compared with prior art, has following beneficial effect: this fracture setting device is simple and compact for structure, safe and convenient to use, adjust simply, and by constant, lasting stress conduction and controlled pressurization, reduce the wound of operation, reduce the amount of bleeding of operation, realize Wicresoft and reset; And can, by coordinating the reset arm of difformity structure, realize the reduction of the fracture of diverse location.This device is not only applicable to fracture of pelvis, is also applicable to the reset of long bone fracture, intra-articular fracture and fixes.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is described further.
Fig. 1 is structural representation of the present utility model (reset arm has been installed).
Fig. 2 is structural representation of the present utility model (reset arm is not installed).
Fig. 3-Fig. 6 is the structural representation of difformity structure reset arm.
In figure: the hollow sliding bar of 1-, 101-chute, 2-guide holder, 3-draw-in groove, 4-toggle switch, 5-fixed handle, 6-flexible handle, 7-unlock button, 8-reset arm, 801-grab, 802-slide opening, the fixing pressurizing block of 803-, 804-base.
The specific embodiment
Referring to Fig. 1-Fig. 3, the present embodiment comprises reset arm 8, hollow sliding bar 1, guide holder 2, fixed handle 5 and flexible handle 6.Wherein reset arm 8 is made up of base 804, fixing pressurizing block 803 and grab 801, and grab 801 is connected with base 804 by fixing pressurizing block 803.Hollow sliding bar 1 is slidably inserted in guide holder 2, base 804 is provided with circular slide opening 802, reset arm 8 is slidably inserted on hollow sliding bar 1 by slide opening 802, and flexible handle 6 is fixedly connected with guide holder 2, and flexible handle 6 is flexibly connected with guide holder 2 by bearing pin.
On the outer wall of hollow sliding bar 1, be provided with two symmetrical chutes 101, guide holder 2 is provided with the draw-in groove 3 being slidably matched with chute 101 at flexible handle 6 ends, and the shape of chute 101 and draw-in groove 3 matches each other, hollow like this sliding bar 1 can be in the interior slip of guide holder 2, but can not axial rotation.The base 804 of reset arm 8 is provided with unlock button 7, unlock button 7 coordinates with chute 101 positioning and lockings on hollow sliding bar 1, unclamp unlock button 7, base 804 can be around hollow sliding bar 1 axial rotation, press unlock button 7, base 804 can be fixed on chute 101, now base 804 cannot be around hollow sliding bar 1 axial rotation.Guide holder 2 is also provided with toggle switch 4 at fixed handle 5 ends.
When use, can configure the reset arm 8 of difformity structure, shown in Fig. 3 and Fig. 4 is the reset arm with fixing pressurizing block 803, the wherein shape difference of grab 801; Position shown in Fig. 5 and Fig. 6 is without the reset arm of fixing pressurizing block 803, and grab 801 is directly fixed on base 802, wherein the shape difference of grab 801.Select different reset arm 8, can reach the reset effect of different parts.
The use procedure of this device is as follows:
According to operative site difference, select different reset arm 8, reset arm 8 is inserted on hollow sliding bar 1, after a selected direction, press unlock button 7, reset arm 8 is fixed in chute 101; Need to adjust reset arm 8 direction time, unclamp unlock button 7 spinning reduction arm 8 to locking positioning again after another chute 101.Press down toggle switch 4, hollow sliding bar 1 is slided to desired location, adjust reset arm 8, guarantee that the grab 801 of reset arm 8 front ends can catch on cortical bone, stir flexible handle 6 hollow sliding bar 1 is pushed ahead and reseting fracture piece, constant persistent pressure is until reach the best reduction of the fracture step by step; Kirschner wire can be squeezed into and be needed fixing position by hollow sliding bar 1, and take this Kirschner wire as guide pin, cannulated lag screw is squeezed in guiding, completes the fixed reset of fracture.When release, press toggle switch 4, and manually retract hollow sliding bar 1, first reset arm 8 is separated with sclerite, after guide holder 2 is separated with Kirschner wire.
