In-vitro universal orientator for intramedullary needle blind locking for limb fracture

Abstract

The invention provides an in-vitro universal orientator for limb fracture intramedullary needle blind locking, and relates to the technical field of medical instruments, the in-vitro universal orientator comprises an intramedullary nail, the intramedullary nail is fixedly installed in a bone of a fracture part of a patient, a positioning frame of a positioning module can freely change the use position, and the intramedullary nail is used for fixing the intramedullary nail; therefore, the intramedullary nail can rotate along the axis position of the intramedullary nail to change the using and positioning positions, meanwhile, the guiding direction of the guiding module can be freely changed, rapid coarse adjustment and accurate fine adjustment can be achieved when guiding of the guiding module is convenient to adjust, use is convenient, and the practicability is high. Meanwhile, the positioning assembly can be matched with different intramedullary nails for treatment, and the problems that the position of a guide hole groove in a near-end guide rod of an existing intramedullary needle orientator is fixed, and one type of near-end guide rod can only be fixed with an intramedullary needle matched with the near-end guide rod for use; and when different intramedullary needles are used, different types of near-end guide rods need to be used.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an extracorporeal universal orientator used for blind locking of intramedullary needles for limb fractures. Background technique [0002] At present, in the treatment of patients with limb fractures, it is necessary to use intramedullary needle fixation. Intramedullary needle fixation is to insert a pulp needle of suitable size and length into the medullary cavity on both sides of the fracture end. In the operation to fix the fracture, the fixation of the intramedullary needle requires the use of a guide device to fix the medical device such as the intramedullary needle inside the bone of the patient's affected area. [0003] However, as far as the current intramedullary needle guide is concerned, the position of the guide hole groove inside the rod body of the proximal guide rod is fixed, so that one type of proximal guide rod can only be fixed with the matching intramed...

Problems solved by technology

[0003] However, as far as the current intramedullary nail orientator is concerned, the position of the guide hole groove inside the rod body of the proximal guide rod is fixed, so that one type of proximal guide rod can only be fixed with the matched intramedullary nail Use, different intramedullary nails need different types of proximal guide rods when used, which is inconvenient to use, poor adaptability, and low practicability
