Nail taking system and method for suprapatellar approach tibia intramedullary nails

Abstract

The invention relates to the technical field of medical equipment, in particular to a nail taking system and method for suprapatellar approach tibia intramedullary nails, and the nail taking system at least comprises the following processes: 1, positioning by adopting a positioning guide needle; 2, adopting an operating table environment capable of transmitting X-rays; and 3, taking out the intramedullary nail by the original suprapatellar approach by a nail taking bolt, a sliding weight guider and a hollow screwdriver according to the guidance of the positioning guide pin. The problem that suprapatellar approach nail taking is difficult can be solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nail removal system and a nail removal method for suprapatellar approach tibial intramedullary nails. Background technique [0002] The technique of tibial intramedullary nailing was first proposed and applied by Kuntscher, from the initial 90° knee flexion position to the current knee joint slightly flexed position, so that the needle insertion point at the proximal end of the tibia can be fully exposed, so that the needle can be inserted in the flexed position Relatively easier. There are two common surgical approaches for tibial intramedullary nailing: incision of the patellar tendon and parapatellar tendon. In this way, the entry point and direction of the intramedullary nail are very clear. Suprapatellar Approach Tibial intramedullary nailing (SPN) is an alternative to the standard infrapatellar approach. Recently, due to the relatively wider indications of th...

Problems solved by technology

[0003] However, suprapatellar approach intramedullary nails are difficult to remove from the original suprapatellar approach, which is often considered by the academic community as a potential shortcoming of the suprapatellar approach technique

At present, most scholars use the infrapatellar approach to take the suprapatellar approach intramedullary nails, but an additional infrapatellar incision is added, which has risks such as anterior knee pain and scar formation, and is especially not suitable for many people who need to squat and kneel for a long time due to work and other reasons.
