minimally invasive reset

Abstract

The invention discloses a minimally invasive restorer which is used for breakage bone conducting transverse restoration traction. The minimally invasive restorer comprises a fixing block. An upper through hole and a lower through hole are formed in the fixing block transversely, wherein the upper through hole is parallel to the lower through hole. A first threaded hole which is communicated with the upper through hole is formed in the top end of the fixing block, a first bolt for fixation is installed in the first threaded hole, a semi-circle step pole handle of a drag hook penetrates through the upper through hole to extends out, the first bolt and the upper plane of the semi-circle step pole handle of the drag hook are locked to each other, and therefore the drag hook is fixed in the fixing block, a handle is fixed at the tail end of the pole handle of the drag hook, an adjusting threaded rod penetrates through the lower through hole to extend out, a left nut and a right nut are respectively arranged on the portion, outside the fixing block, of the adjusting threaded rod, the left nut and the right nut can axially fix the adjusting threaded rod into the fixing block, and the tail end of a bone ejecting needle is connected with the end portion of the adjusting threaded rod through a connecting sleeve. According to the structure, the minimally invasive restorer is safe and stable in the operation process, high in efficiency, and capable of greatly reducing wound area when an external fixing support is used.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a minimally invasive reset device used for lateral reduction and traction of fractured bones of patients' limbs. Background technique [0002] In orthopedic surgery, when performing surgical treatment on the fractured bones of the patient's injured limbs, it is necessary to reset and traction the fractured bones first, so as to provide a good prerequisite for the next step of the operation. At present, when performing surgery on the bone at the fracture, it is first necessary to manually pull the bone at the fracture to make a radial movement. Under the artificial traction, the doctor uses a scalpel to cut a large opening in the outer skin tissue of the bone at the fracture, and then Insert the pry hook into the bone that requires lateral traction, use the pry hook to pry the bone, and perform lateral traction on the bone to align the broken bones, and then fix and banda...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the above-mentioned traditional surgical method are: 1. During the operation, someone needs to pry the bone for lateral reduction and traction, and the pry hook must always be maintained at the position after prying until the bone at the fracture is docked and fixed. Not only is it labor-intensive, but also because of the instability of manual operation, it brings inconvenience and unsafe factors to the doctor's operation. A large incision was made on the outer skin tissue of the bone, which increased the trauma area of ​​the patient
