Negative pressure environment bone cement single hole injection fracture fixation system and working method

Abstract

The disclosure provides a bone cement single-hole injection fracture fixation system in a negative pressure environment and a working method, which belong to the technical field of fracture fixation equipment. The system includes a negative pressure device, a first hollow nail, a second hollow nail and a bone cement injection device The negative pressure device communicates with one end of the first hollow nail through the first tube, and communicates with both ends of the first hollow nail; the bone cement injection device communicates with one end of the second hollow nail through the second tube, and the second The two ends of the hollow nail are connected; the present disclosure injects bone cement into the medullary cavity under a negative pressure environment through the cooperation of the negative pressure device and the bone cement injection device, so that the bone cement can quickly fill the medullary cavity, and at the same time, the bone cement can allow The human body directly absorbs, avoids the internal or external damage of the existing external fixation and internal fixation methods, improves the fixation effect, and reduces the patient's pain.

Description

Negative pressure environment bone cement single hole injection fracture fixation system and working method technical field The present disclosure relates to the technical field of fracture fixation equipment, in particular to a single-hole injection of bone cement in a negative pressure environment for fractures Fixing system and working method. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. Present fracture treatment technology is more and more towards minimally invasive, intelligent development, after completing minimally invasive fracture reduction, it is necessary to To find a minimally invasive fixation method, the popular ones are external fixation and internal fixation, and the representative one is external fixator Fixation, plate fixation, and intramedullary nailing. However, the inventor of the present disclosure has found that the existin...

Problems solved by technology

[0004] However, the inventors of the present disclosure have found that the existing fixation methods have their shortcomings. After the external fixation time is too long, there is a high probability of pinhole reaction, the skin color is dark in the later stage, and the life of the patient is inconvenient. The deficiency of internal fixation is mainly reflected in the destruction of blood supply. Heals slowly, often requiring secondary surgery, and often requires widening the incision for implant placement, causing further damage
