Description
Technical Field
The utility model belongs to the technical field of medical instruments, relates to a fracture restorer, in particular to a point-surface combined minimally invasive combined fracture restorer; is particularly suitable for minimally invasive clamping reduction of limb tubular fracture.
Background
With the rapid development of modern surgical techniques, minimally invasive orthopedic techniques and concepts are applied to clinical treatment more and more, smaller incisions are designed and exposed, less invasive soft tissues are stripped, periosteum blood circulation is kept more, fracture healing is promoted, and related complications such as infection are reduced; the traditional fracture restorer or bone holding forceps have wide and heavy clamping parts, are vertical to the incision and have wide soft tissue stripping; and the vertical cut is not beneficial to the implantation of internal fixtures such as steel plates.
Disclosure of Invention
The utility model discloses a fracture restorer, which aims to solve the problems that in the prior art, a clamping part is wide and thick, soft tissues are widely stripped, a vertical cut is not beneficial to implantation of internal fixtures such as steel plates and the like.
The utility model comprises a corner cantilever, a clamping head and a pressurizing bolt locking device; the two corner cantilevers are symmetrically arranged in structure and are hinged in an X shape in a crossed manner; the two corner cantilevers are provided with a turn perpendicular to the hinged symmetrical center line C at one side end part, and a quick-change connector connecting structure of a clamping head is arranged at the tail end of the turn; the clamping head is connected with the quick-change connector of the corner cantilever and is parallel to the symmetrical center line of the corner cantilever; the pressurizing bolt locking device is arranged on the other side of the corner cantilever opposite to the clamping head; the pressurizing bolt locking device comprises a guide stud, a tension spring and a locking nut; a corner cantilever is provided with a guide stud through hole; the guide stud is vertical to the symmetrical center lines of the two corner cantilevers, one end of the guide stud is fixedly arranged on one corner cantilever, and the other end of the guide stud penetrates through the guide stud through hole of the other corner cantilever; the tension spring is arranged on the guide stud between the two corner cantilevers; the locking nut is fixedly connected with the guide stud to limit the distance between the clamping heads on the two corner cantilevers; when the clamping device works, the clamping head is clamped and reset in parallel with the notch.
The clamping head comprises a point type resetting device and a tooth-shaped head resetting device; the point-type reset device is connected with a corner cantilever quick-change connector; the tooth-shaped head resetting device is connected with the other corner cantilever quick-change connector; the point-type resetting device and the tooth-shaped head resetting device are clamped and reset by the notches in parallel.
When in use, the device is clamped and reset according to the minimally invasive soft tissue stripping range requirement of the limb tubular fracture, and blood circulation is kept to the maximum extent.
The utility model has the positive effects that: the clamping position of the restorer adopts a point type head and a tooth-shaped head to reduce the stripping range; can be selected according to different parts and injury types of the fracture, is favorable for preserving blood circulation, is favorable for anatomical reduction of the fracture, and maintains strong reduction clamping force. The unique cantilever corner design parallel incision clamping resets, implants the headspace for interior fixture, easily operates, reduces the operation degree of difficulty, save time.
