Description
Technical field
The utility model is related to a kind of Medical Devices, and in particular to a kind of bone forceps in treating fracture operation.
Background technology
Plate fixation technology is the treatment common effective means of backbone, especially setting board of skeleton end fracture.In operation, only exposure
Normal bone in fracture site distally and proximally does not expose fracture site directly, make osteogenic tissue around fracture and
The blood fortune of soft tissue is retained；Indirect reduction is carried out to fracture under the monitoring of C arm X-ray machines；Under muscle layer, outside periosteum be inserted into connect
Bone plate crosses fracture site and reaches distal side backbone；In remote, the close both sides of fracture site bone plate is completed with conventional method respectively
It is fixed.It is effectively reduced the range and degree for removing periosteum and soft tissue in surgical procedure from bone fragment, is alleviated or avoided
Further damage and destruction to bone fragment blood supply, obtain good therapeutic effect.
During surgery, the position of plate fixation is extremely important, and usually bone plate is placed on centered on fracture
On bone face, then adjusting synthetism Board position, it is ensured that the setscrew at bone plate both ends pierces in bone cavity, rather than on bone wall.So
And since bone is in certain camber, it is implanted at present in bone plate surgical procedure, needs to adjust bone plate end positions repeatedly,
So that inside its both ends screw hole alignment bone cavity, causes operation waste for a long time, influence the best rescue time of patient, increase
The danger of patient.Also, if the screw of any one end is pierced accidentally on bone wall, it will cause additional bone wound, cause
Clinically has there are a lot of similar malpractices in new fracture.
Invention content
Goal of the invention：The utility model aim is in view of the deficiencies of the prior art, to provide one kind and be provided simultaneously with and hold bone, connect
Bone plate screw aims at and is fixed temporarily the growth of fracture setting plate both ends nail hole dynamic collimation device of effect.
Technical solution：Growth of fracture setting plate described in the utility model both ends nail hole dynamic collimation device, including by two tong arms and
The bone forceps main body of handle composition, two tong arms are interconnected to form pivot structure by connecting shaft, are fixed in the connecting shaft
One hollow sleeve, the sleeve are located at the outside of plane residing for the bone forceps main body, arranged direction and the bone forceps main body
Symmetry axis direction it is consistent；Locating rod is equipped in the sleeve, the length of the locating rod is more than the length of the sleeve,
The top of locating rod passes through the sleeve, when bone is clamped in two tong arms of the bone forceps main body, is inserted into the spiral shell of bone plate end
In hole.
Further preferably technical solution is the utility model, and internal thread is provided on the inner wall of the sleeve, described fixed
The tail end of position bar is provided with corresponding external screw thread, and the position of the locating rod is coordinated by internal and external screw thread to be determined.
Preferably, the top of the locating rod is provided with the screw thread to match with the screw hole of the bone plate end.
Preferably, locking device is provided on the handle of the bone forceps main body, the locking device adjusts the bone forceps master
The chucking power of body.
The specifically used method of the bone forceps of the utility model is：After bone plate is placed into fracture site, in bone plate one
Above terminal screw hole, bone forceps is probeed into, two tong arms clamp bone, then are locked with locking device；By in locating rod insertion sleeve, rotate
Locating rod is inserted into end in the screw hole of bone plate, and locking bone fracture plate dynamic collimation system is collectively formed with locating rod in two tong arms.
Advantageous effect：（1）The growth of fracture setting plate both ends nail hole dynamic collimation device of the utility model, the plane residing for bone forceps
Outside is provided with sleeve, and when bone is clamped in two tong arms of the bone forceps main body, locating rod passes through sleeve and is inserted into bone plate end
In the screw hole in portion, locking bone fracture plate dynamic collimation system is collectively formed with locating rod in two tong arms, can be by bone plate one end dynamic
It is fixed on fracture site, makes it that can surround bone axis direction and rotates, while remaining that screw hole vertical direction is located at bone cavity
Interior, effective dynamic fixation bone fracture plate keeps its screw hole to lean on entad against bone cavity always, avoids the generation of fortuitous event,
Assistant's quantity can be reduced simultaneously, reduces the adjustment plate placement time, mitigates working doctor intensity, mitigate patient suffering；
（2）The tail end of locating rod is provided with the screw thread to match with sleeve in the utility model, and locating rod passes through with sleeve
Screw thread is connected, can flexible modulation locating rod position, to adjust the elasticity between bone plate and bone face, convenient for bone plate
Position adjusts；
（3）It is provided with the screw thread consistent with existing bone plate screw hole in the market on the top of locating rod in the utility model,
It is applied widely, it is versatile；
（4）The utility model is provided with forced locking device on handle, and the chucking power of the bone forceps main body, hand is adjusted
Clamp position is kept during art, need not manually help, further save manpower.
