The utility model discloses a frame fixing device is referred to in patent document CN212755863U with reference to bone surgery navigation, the device includes the link, link one end is connected with the navigation and refers to the frame, and the screw hole has been seted up to the other end, the screw hole cooperation is connected with the threaded rod, the threaded rod outside cover has the collar, the one end that the link was kept away from to the threaded rod is connected with adjust knob, be connected with the connecting rod on the collar outer disc, the one end that the collar was kept away from to the connecting rod is connected with the fixing base, the bottom of fixing base is connected with a plurality of kirschner wires, inserts near the affected part skeleton through the kirschner wire with fixed navigation reference frame, and such fixed mode still can cause certain injury to patient's foot when using on the patient of low limbs fracture, carries over down the wound, has the risk of concurrent infection after the operation.

Disclosure of Invention

The utility model aims to solve the technical problem of providing the lower limb fracture navigation reference frame fixer, which can fix the navigation reference frame on the foot when treating the lower limb fracture, can not damage the foot of a patient, reduces the trauma and reduces the infection risk of postoperative concurrent wounds.

In order to solve the problems, the utility model adopts the following technical scheme:

the utility model provides a lower limb fracture navigation reference frame fixer, includes the body, is equipped with the standing groove of putting into the foot on the body, and the inner wall profile of standing groove is laminated mutually with half foot of patient at least to the body has the leg side opening that is linked together with the standing groove, and the leg side opening link up to the body outside for through the shank, offered the fixed orifices on the side that the body was used for exposing half foot, this fixed orifices is used for fixed navigation reference frame, is provided with the rope hole that is used for passing the ligature rope on the body.

As a further improvement of the above technical scheme:

the opposite side surface of the body provided with the fixing hole is a plane, so that the body can be horizontally placed on an operation table through the plane, and the probability of movement of the body and feet in the operation is reduced.

The body is provided with the toe hole, the toe hole is communicated with the placing groove, and the toe hole is communicated to the outside of the body and used for exposing the toe, so that the toe part is more breathable and comfortable.

The inner wall of the placing groove is provided with a piece of cloth to prevent the edges and corners of the body from scratching the feet of the patient.

The rope holes comprise two rope fixing bodies and feet, and the rope holes are respectively formed in two sides outside the placing groove, so that the rope fixing bodies and the feet can be bound on the two sides, and the fixing force is balanced.

The utility model has the beneficial effects that:

in the lower limb fracture navigation reference frame fixer, a patient can put the foot into the placing groove, and the rope passes through the rope hole by using the binding rope, and the rope is wound around the foot, so that the foot of the patient and the body are bound and fixed on an operation bed, and the navigation reference frame can be inserted into the fixing hole through the fixing needle for fixing, so that the navigation reference frame can be fixed on the upper side of the foot of the patient, and the fixing needle is inserted on the body, so that the foot of the patient cannot be damaged.
