Description

Traction reset external fixing frame assembly

Technical Field

The utility model belongs to the technical field of external fixation frames for fracture, and particularly relates to an external fixation frame assembly accompanied with traction reduction.

Background

The external fixing support for fracture is mainly formed by connecting external fixing support rods through external fixing screws. The external fixing support is mainly used for various open fracture injuries with serious limbs, maintains the stability and the position of fracture as much as possible and reduces the fracture dislocation risk. In the case of fracture crushing or infection, the fracture is fixed externally and then the upper and lower ends of the fracture are fixed. The lead fixation is coupled to the external fixator and then adjusted to the extent that the fixation may be performed for comminuted fracture or where internal fixation is not appropriate and to assist in fracture healing.

The external fixing frame for fracture has the functions of supporting and fixing. After fracture, some patients have no way to perform surgical treatment immediately or to perform internal fixation treatment due to physical reasons or to the extent of soft tissue and open contamination of the skin at the fracture site, so that only external fixation stents can be used for treatment. The external fixing bracket does not cross the broken end of the fracture and is far away from the fracture part, so the safety of tissues is relatively better, the infection after the fracture caused by pollution of the broken end is avoided, and even osteomyelitis can be avoided. So the external fracture fixation frame is very important in the treatment of fracture.

When current outer frame is fixed to two sections of fracture, need at least two staple in every section just can ensure that outer frame is fixed after, two sections of fracture can not appear swinging, rotate and axial telescopic movement, but during actual operation, fix two inboard frame holes earlier, then fix two outside frame holes, because two inboard frame holes can freely select fixed position when being fixed, easy fixing, but two outside frame holes are fixed, can appear sometimes that the hole site is issued and is aimed at blood vessel or nerve, can't directly nail down, lead to outer frame fixed difficulty, even need punch fixed problem again.

In addition, the existing external fixing frame is generally made of hard cylindrical metal rods, and is fixedly combined through connecting fasteners and the like to form a stable and firm frame body when in use, so that the fracture position is assisted to be positioned and recovered. When the existing external fixing frame is used, a certain problem exists, a large amount of tissues such as blood vessels and nerves exist in a human body, and in order to prevent the locking nails inserted into broken bones from damaging the blood vessels or the nerves, a hard metal rod piece is required to be bent, or the hard metal rod piece is required to be connected with a fastener through deflection to avoid the blood vessels or the nerves.

The common outer frame metal rod is quite firm, the bending is time-consuming and labor-consuming, the positioning is not easy, the connecting fastener deflects to avoid the blood vessel easily, but the locking and the fixing are difficult.
