Abstract
The utility model relates to a pair of fixation forceps for traction and reduction of fractures. The utility model comprises a pair of holding forceps. The utility model is characterized in that two holding end heads of the forceps are provided with small holes in which hollow needle pipes are fixed. Cross nails can be conveniently nailed into a bone-knitting position from the small holes and the needle pipes by utilizing the utility model. Nail penetration almost has no operation wound. The utility model has the advantages of accurate positioning and direction guiding, convenient utilization and operation, simple structure, etc. The utility model is suitable for bone knitting for bone fractures on child humerus condyles and treatment of bone fractures of the distal epiphysis slip of a femur.
Description
This utility model relates to a kind of improved medical apparatus, especially adopts the medical apparatus of closed reduction intersection pin inner fixed law treatment children's supracondylar fracture of the humerus.
Children's's supracondylar fracture of the humerus, it is the most common a kind of disease that also the most easily disables, traditional Therapeutic Method is the manual reduction external fixation, remove external fixation about 4 weeks, as the failure that resets then adopts operation method to cut, the broken ends of fractured bone resetted, and to intersect nail with two draw points fixing in the back, makes it to keep correct para-position and heal.Various complication such as when adopting operative treatment, easily infect, joint accretion, nervus vasculairs are impaired.At present, the up-to-date Therapeutic Method of children's's fracture of humeral condyle is that closed reduction intersects the pin internal fixation, and the difference of this method and preceding method is, directly will intersect the man-to-man broken ends of fractured bone of pin by skin behind the manual reduction.This method can reduce operation wound and post-operative complication to greatest extent.During with this method synthetism, traction earlier, after reset, after x-ray examination is errorless, the ailing that will intersect is again gone into the broken ends of fractured bone, thus higher to equipment and specification requirement, especially require intersection to follow closely and should hammer into accurately and rapidly, this is to guarantee the key that accurately resets.At present, mainly by doctor's feel control, it is wayward to hammer into angle for the accuracy of intersection ailing implantation site and angle, and operating technology is had relatively high expectations, for making this method easy operating, the clinical middle corresponding reduction by traction medical apparatus of being badly in need of.
The purpose of this utility model is to provide a kind of orthopaedics reduction by traction fixation clamps, and these pincers reduction by traction and making easily intersect nail and hammer into quickly and accurately.
The purpose of this utility model is achieved in that
A kind of orthopedics traction and reposition positioning clamp, it comprises a gripper clamp, its improvement is that two clamping terminations of described gripper clamp are provided with aperture 2.
For improving the guiding degree of accuracy, above-mentioned positioning clamp is fixed with hollow needle tubing 3 in the described aperture.
For preventing slippage, above-mentioned positioning clamp, the aciculiform termination bending of described hollow needle tubing, bending angle a is 5 °-60 °.
For ease of adjusting, last rheme positioning clamp, described hollow needle pipe racks has base 4, and base end face card leans against on the aperture end face, and screw rod or screw on the base are arranged in aperture.
Above-mentioned positioning clamp, described base, aperture card mutually lean on the end face tooth that is respectively equipped with engagement on the end face.
This utility model is at jaw clamping termination design aperture and hollow needle tubing, make to intersect and follow closely and to hammer into synthetism place by aperture and needle tubing easily, drift bolt does not have operation wound substantially, and have positioning and guiding accurately, use characteristics such as easy to operate, simple in structure, the synthetism of bone fracture is used on not only suitable children's's condyle of humerus, and the treatment that also can be used for bone injury such as distal femur epiphysis slippage is used.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is an another kind of base structural representation in this utility model.
Consult Fig. 1,2, embodiment illustrated in fig. 1ly be provided with an embodiment of engaging tooth for base and the aperture end face that reclines.1 is the gripper clamp caliper among the figure, aperture 2 is located on the clamping termination, the bending angle a of hollow needle tubing 3 aciculiform terminations is at least 5 °, otherwise during the traction of the clamping broken ends of fractured bone, because of jaw opens, hollow needle tubing is outward-dipping, the broken ends of fractured bone is easy to along the slippage of needle tubing inclined-plane, if after this bending, can firmly broken ends of fractured bone hook be lived in the time of clamping, not only clamping is firm, also can reduce required chucking power.Base 4 is a plate-like, and the screw 7 in the aperture screws in the base screw, and when unscrewing screw, base, the intermeshing end face tooth of aperture are thrown off, and rotate the importing angle of the hollow needle tubing of base scalable.
In the base structure shown in Figure 3, base 4 is a column, and hollow needle tubing 2 fixedly inserts in the base, and the screw rod 5 on the base applying end face unscrews the locknut 6 on the screw rod, the importing angle of the hollow needle tubing of rotation base 4 scalable by stretching out in the aperture 2.Certainly, the version of base is not limited to above-mentioned two kinds, and the aperture of clamping termination is round taper hole also, and base can be arranged to corresponding conical rod, and the screw rod that screws on the conical rod can realize conveniently that also hollow needle tubing imports the adjusting of angle.
