Abstract
The utility model discloses a pair of limb fracture two-way restoration traction forceps comprising a forceps body (1), an arc plate forceps head (2), a forceps shaft (6) and a clamping screw rod (3); the traction forceps are characterized in that the forceps shaft (6) is connected with a section of elastic screw rod (5); one side of the forceps body (1) is provided with another same forceps body (1') side by side, and a forceps shaft of the forceps body (1') is provided with a reverse thread elastic screw rod (5'); the elastic screw rod and the reverse thread elastic screw rod (5 and 5') are respectively arranged in the same spiral barrel (7) in a rotating way; and the handle end parts of the forceps body (1 and 1') are respectively welded with a screw rod and a reverse thread screw rod (8 and 8') which are respectively arranged inside a corresponding spiral barrel (9) in a rotating way. By adopting the forceps to clamp two broken ends of fracture at the same time and being provided with a corresponding locating mechanism, the limb fracture two-way restoration traction forceps can realize that the two broken ends of fracture is clamped and drawn at the same time, also can realize deflection and twisting, and is especially applicable to long bone fracture reduction surgery.
Description
Technical field
This utility model relates to a kind of improvement of reduction of the fracture gripper clamp, specifically a kind of limb fracture two-way reset pulling clamp.Mainly be applicable to the long bone of limbs fracture operation.
Background technology
Long bone of limbs reduction of the fracture operation is modal a kind of reduction of the fracture operation in the orthopaedics, and what the fracture that vehicle accident causes was maximum also is extremity fracture.Reduction of the fracture operation is exactly to adopt gripper clamp with fracture tension alignment usually, and will aspire for stability, and must not rock and misplace, and steps up with steel plate then, and fixes by nail and sclerotin.Present employed gripper clamp comprises that caliper, pincers axle, the tabular binding clip of arc and clamping screw constitute, and the tabular binding clip of arc is connected vice jaw part by rotating ear, by the tabular binding clip of arc fracture end is clamped, and clamps fracture end by clamping screw, and then beats nail.The deficiency of this gripper clamp is, can not be simultaneously the two ends of fracture be clamped simultaneously, and want the above operation of two people, often because of not simultaneously or different operating cause dislocation, fixing instability, this has not only prolonged operating time, and has reduced the operation quality.
Summary of the invention
The purpose of this utility model be to provide a kind of can be fixing simultaneously to the two ends of fracture, and can the tractive positioned in alignment, a people can operate, easy to use flexibly, he can improves reattachment surgery quality and speed, is exclusively used in the limb fracture two-way reset pulling clamp of long bone of limbs fracture.
For reaching above purpose, the technical scheme that this utility model adopted is: this limb fracture two-way reset pulling clamp, comprise caliper, the tabular binding clip of arc, pincers axle and clamping screw constitute, the tabular binding clip of arc is connected vice jaw part by rotating ear, pommel middle part at caliper is provided with clamping screw, it is characterized in that: at inner fixedly connected the preceding paragraph elasticity screw rod of pincers axle, a side of caliper side by side establish another caliper, also establish the tabular binding clip of arc at the nip part of another caliper, its pommel middle part also is provided with clamping screw, the also fixedly connected the preceding paragraph in inboard left-hand thread elasticity screw rod opposite at its pincers axle with elasticity screw flight direction, elasticity screw rod and left-hand thread elasticity screw rod are rotated in respectively in the two ends of same barrel, two calipers are connected as one, rotation by barrel simultaneously, regulate the distance between caliper and another caliper, thereby realize that the two ends of fracturing retract or to closely; Screw rod is all welded in inboard in the upper and lower pommel portion of caliper, the left-hand thread screw rod opposite with the screw flight direction all welded in inside at the upper and lower pommel of another caliper, screw rod and left-hand thread screw rod are rotated in respectively in the two ends of corresponding barrel, rotation by barrel, realize the deflection of jaw or tension synchronously, thereby the alignment of physiological bending deflection is pressed at the two ends of realizing fracture.
This utility model is also implemented by following measure: the width of the tabular binding clip of arc on the tabular binding clip of the arc on the described caliper and another caliper is 2-5cm, all pastes one deck medical gauze layer on its inwall; The lower end of the clamping screw on the clamping screw on the described caliper and another caliper is all rotated joint by bulb and is connected on the pincers handle, and butterfly nut is gone up in its upper end all rotation.
The beneficial effects of the utility model are: compare with the reduction of the fracture gripper clamp of present use, owing to adopted two identical clamps, add simultaneously and hold from two broken ends of fractured bone of fracture, and be provided with corresponding three-way tractive detent mechanism, can realize that two broken ends of fractured bone of fracturing step up simultaneously, tractive, alignment, location, can also realize deflection, twisting,, be specially adapted to long bone of limbs reduction of the fracture operation to meet the physiological bending of fracture.

Fig. 1, look sketch map for structure master of the present utility model.
The specific embodiment
Make this utility model with reference to Fig. 1.This limb fracture two-way reset pulling clamp, comprise caliper 1, the tabular binding clip 2 of arc, pincers axle 6 and clamping screw 3 constitute, the tabular binding clip 2 of arc is connected vice jaw part by rotating ear 4, clamp by the broken ends of fractured bone that the tabular binding clip 2 of arc will be fractured, pommel middle part at caliper 1 is provided with clamping screw 3, clamp a broken ends of fractured bone of fracture by clamping screw 3, it is characterized in that: at inner fixedly connected the preceding paragraph elasticity screw rod 5 of pincers axle 6, a side of caliper 1 side by side establish another caliper 1 ', another caliper 1 ' nip part also establish the tabular binding clip 2 of arc ', its pommel middle part also be provided with clamping screw 3 ', also fixedly connected the preceding paragraph in inboard of its pincers axle left-hand thread elasticity screw rod 5 opposite with the hand of spiral of elasticity screw rod 5 ', elasticity screw rod 5 and left-hand thread elasticity screw rod 5 ' respectively are rotated in the two ends of same barrel 7, two calipers are connected as one, rotation by barrel 7 simultaneously, regulate caliper 1 and another caliper 1 ' between distance, thereby realize that the two ends of fracturing retract or to closely; Screw rod 8 is all welded in inboard in the upper and lower pommel portion of caliper 1, another caliper 1 ' the inside of upper and lower pommel all weld the left-hand thread screw rod 8 opposite with screw rod 8 hand of spirals ', screw rod 8 and left-hand thread screw rod 8 ' be rotated in respectively in the two ends of corresponding barrel 9, rotation by barrel 9, realize the deflection of jaw or tension synchronously, thereby the alignment of physiological bending deflection is pressed at the two ends of realizing fracture.
The tabular binding clip of arc on the described caliper 12 and another caliper 1 ' on the tabular binding clip 2 of arc ' width be 2-5cm, all paste one deck medical gauze layer 10 on its inwall; Clamping screw 3 on the described caliper 1 and another caliper 1 ' on clamping screw 3 ' the lower end all rotate joint 11 and be connected on the pincers handle by bulb, butterfly nut 12 is gone up in its upper end all rotation.When using this utility model, can be by an end of caliper 1 fixed clamp long bone fracture, the other end by another caliper 1 ' fixed clamp long bone fracture, again by rotating barrel 7, barrel 9 is rotated at the two ends of the tractive or the long bone fracture that furthers simultaneously, and fracture is alignd by physiological bending, after complete para-position, the reattachment surgery method is carried out routinely again.
