Abstract
The utility model provides a four-claw bone holder having a press plate with holes, which is formed into hand vices shape by the connection between a straight handle and a bend handle through a small shaft. The clamp part is formed into ellipse semi embracing type, and each clamp end part branches off in V shape to form four jaws. Two tips are formed at each jaw end. The middle of the clamp part is provided with a press plate with holes, and the press plate is connected with a connecting rod in T shape. The regulation and fixation of the embracing of the four jaws at the clamp part which is controlled by a slide block and a regulating screw are realized by the wing nut of the movable pulling rod. The utility model provides standing facilities for fracture reduction surgery with time saving and labour saving and reduces exposure time in surgery to make the surgery more perfect.
Description
Technical field:
This utility model is to belong to keeping the interim stable medical apparatus and instruments of surgery fracture.
Background technology:
In clinical orthopaedics open reduction internal fixation operation, bone holder is indispensable operating theater instruments, in the process of treatment extremity tubulose shaft fracture, adopt open reduction, temporary fixed, folding open reduction steel plate screw or three steps of intramedullary pin internal fixation, and use one to stablize the stability that apparatus is kept the back fracture end that resets temporarily, be related to the operation success or failure.For a long time, the orthopedist is normally used all to be the three-jaw bone holder, apparatuses such as lion mouth pincers are finished temporary fixed, according to the BO theory, resetting of fracture fixing need reach the stable and local soft tissue balance between complete, when using the three-jaw bone holder, because undue stripping periosteum, even damage its nutrient artery, the damage of the local blood fortune of fracture is increased the weight of, cause nonunion, the incidence rate that delayed union and sequestrum form increases, and brings very big damage to the patient, causes great misery, lion mouth pincers wait other reduction of the fracture pincers to have above-mentioned disadvantage too, and can only keep the stable of a face of fracture, can not reach the requirement of fracture anatomical reduction fully, so need to improve.
Summary of the invention:
The purpose of this utility model is to use the four paws bone holder of pressing plate with holes, and is stable temporarily to the fracture end after resetting, and making fracture reach the requirement of anatomical reduction, and reduces the damage to fracture end blood fortune, for the implantation of steel plate screw or intramedullary pin provides technical support.
The technical solution of the utility model as shown in Figure 1, connect into the hand vice shape by straight hand lever 1 and bending of the hand handle 2 by little axle, straight hand lever 1 forms the oval formula of embracing that narrows with the pincers portion of bending of the hand handle 2, each clamps the end with V font bifurcated, form the arc four paws, form two tips again at each pawl end, 8 tip points that total formation is vertically arranged.In the middle of ellipse narrows armful formula pincers portion, pressing plate 3 with holes is arranged, 4 one-tenth universal connections of T font of pressing plate 3 with holes and connecting rod, connecting rod 4 passes an end that is fixed on slide block 6 behind the connecting rod base 5 that is fixed on the straight hand lever 1, slide block 6 bottoms are protruded and are cooperated with the surperficial chute of straight hand lever 1, the other end of slide block 6 is connected with adjusting screw(rod) 7, adjusting screw(rod) 7 is to pass the adjusting screw(rod) seat 8 that is fixed on straight hand lever 1, its outstanding end is used for regulating, top is equipped with two spring leafs and is connected between 2 liang of handles of straight hand lever 1 and bending of the hand handle, make certain elastic force holding position is arranged between two handles, active pull rod 9 is arranged at the bottom, one end of active pull rod 9 is fixed on the straight hand lever 1 by universal joint, the other end passes bending of the hand handle 2 and is connected by wing nut 10, in order to regulate and the fixation clamps end state of filling the span of a man's arms.
When in operation, using, fixed the position of filling the span of a man's arms after, regulate adjusting screw(rod) 7, pressing plate 3 with holes slowly is pressed to forward needs operative site, after putting in place, the pedicle screw etc. of can holing.
Description of drawings:
Fig. 1, the four paws bone holder structural representation of pressing plate with holes is arranged.
Wherein: 1, straight hand lever; 2, bending of the hand handle; 3, pressing plate with holes; 4, connecting rod; 5, connecting rod base; 6, slide block; 7, adjusting screw(rod); 8, adjusting screw(rod) seat; 9, active pull rod; 10, wing nut.
The specific embodiment:
This utility model is implemented by such scheme, and its major axis of ellipse of the formula of embracing that narrows in the pincers end is 30～50 millimeters, and minor axis is 20～30 millimeters, and distance is 30～45 millimeters between two pawls of V font bifurcated.
Make series according to actual needs, use for operation.Pressing plate 3 with holes is to adopt ≠ 1 * 10 * 30 (millimeter) sheet material, and the two ends of length direction have the square hole of 8 millimeters of long 10 mm wides, and pressing plate 3 with holes flexibly connects with connecting rod 4, can free rotational angle, and the satisfied needs of performing the operation.
This utility model has been realized the bone of holding of 8 of four paws, adds the pressure holding of pressing plate with holes, reaches interim stable requirement after the reduction of the fracture, for implanting the inside-fixture condition that facilitates, the damage of the local blood fortune of fracture is minimized.Save time, laborsaving, reduce the open-assembly time in the operation, make operation perfect more.
This utility model is simple in structure, easy to operate, is apparatus preferably in the fracture operation.Medical apparatus and instruments enterprise can both go into operation, and is good in economic efficiency.
