Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of Fracture of femur reduction forceps that vertically pressurizes.
Background technology
According to the anatomical structure characteristics of human body, the lateral side of femur edge is that tension side, medial border are on the pressure side.Therefore when fracture took place femur, often there was bigger butterfly bone piece the fracture end inboard.In the operation technique of treatment Fracture of femur, reduction of the fracture pincers commonly used can only offer the tong arm of front end a kind of with clamp the handle handgrip and tighten up the parallel horizontal plus-pressure of direction, after this reduction of the fracture clamps arrogant leg outer side otch implantation open country, the sclerite pressurization that can only be shifted to the fore-and-aft direction of Fracture of femur end impels it to reset.Yet for the sclerite of Fracture of femur end generation inward-outward direction displacement, this reduction forceps routine from the outside long and narrow deeply the wild operation of otch implantation powerless.Generally; the patient is if will remedy the design defect of this apparatus; usually can strengthen the dissection scope of fracture end periosteum and muscle group thereof; the increasing operative region exposes; with this reduction forceps by the thigh front side to inserting fracture end; the sclerite of clamp Fracture of femur end introversion and extroversion shift separation reaches the purpose of reseting fracture.But this large-scale periosteum separates exposure with muscle group, not only strengthen patient's operation wound, increases amount of bleeding, prolongs operating time, has increased operation risk, also prolongs the functional rehabilitation process of postoperative lower limb.Simultaneously, periosteum and muscle group divide the blood fortune of defection heavy damage Fracture of femur end on a large scale, aggravation ischemia, the risk of increasing postoperative fracture bone does not connect.Very harmful to the patient.
The reduction of the fracture pincers of present routine clinical use all can not overcome the above problems well.
The utility model content
The purpose of this utility model is to overcome above defective, provide a kind of simple in structure, easy to use, reduce surgical injury, the firm Fracture of femur of the pressurization effect reduction forceps that vertically pressurizes.
In order to realize the foregoing invention purpose, this utility model provides a kind of Fracture of femur reduction forceps that vertically pressurizes, and it comprises the first caliper element, the second caliper element, movable tong arm, movable bone holding claw; The first caliper element wherein by first-hand handle, first pincers handle, first buckle, fixedly tong arm and fixedly bone holding claw form; The second caliper element is made up of second-hand's handle, the second pincers handle and second buckle; The first caliper element and the second caliper element are connected in one by the first associating axle; The second pincers handle of the movable tong arm and the second caliper element is connected in one by the second associating axle; The movable tong arm and the first caliper element are connected in one by the 3rd associating axle; Movable tong arm and movable bone holding claw are connected in one by the tetrad sympodium; Movable bone holding claw and fixedly bone holding claw be half arc, both inboard occlusal surfaces all have groove.
Above-mentioned a kind of Fracture of femur reduction forceps that vertically pressurizes has a sliding tray at the position, center of movable tong arm, and length is 85% of whole movable tong arm, and the axle center of width and the 3rd associating axle is complementary.
The rectangular aperture of movable tong arm in the first caliper element stage casing runs through, and connected by the 3rd associating axle.
During use, the patient opens the handgrip and the pincers handle of first and second caliper element, movable tong arm of the pincers handle tractive of the second caliper element and the motion of drive activity bone holding claw, bone holding claw separates expansion to make the two and the fixedly tong arm of the first caliper element reach fixedly, and slides along the axial handgrip direction of the 3rd associating.The patient hands unfolded this reduction forceps, through big leg outer side slit, can insert deeply fracture site, the fixedly bone holding claw of reduction forceps and movable bone holding claw are placed both sides inside and outside the fracture end respectively, the patient firmly tightens up handgrip, the pincers handle promotion activity tong arm of the second caliper element also drives its movable bone holding claw motion, make the two fixedly tong arm reach the fixedly longitudinal sliding motion of bone holding claw direction and the clamping fracture end that pressurizes along the axial first caliper element of the 3rd associating, first, the snap-lock of two caliper elements is finished the operation that the sclerite pressurization of implementing the inward-outward direction displacement resets.This motion of tong arm and bone holding claw has formed the vertical plus-pressure that produces along the reduction forceps longitudinal axis, and the horizontal plus-pressure direction of tightening up pincers handle handgrip with the patient is vertical.
This utility model has substantive distinguishing features and progressive with respect to prior art, specifically, the utlity model has following advantage: 1, this reduction of the fracture fixation clamps is simple in structure, easy to use, the vertical plus-pressure that produces along the reduction forceps longitudinal axis makes the patient can adopt the small lateral incision pressurization that resets to be in the fracture of the interior lateral direction displacement in thigh deep.Reduce operation wound, accelerated patient's postoperative rehabilitation.2, the longitudinal axis of this reduction forceps is a linear type, saves the operation technique space.3, the movable bone holding claw of this reduction of the fracture pincers and fixedly bone holding claw be half arc, the key surface of can when the clamping fracture end, more fitting, inboard occlusal groove can be avoided sclerite to slide and cause the pressurization failure that resets, the reduction of the fracture effect stability that pressurizes reliable.
