Zhejiang University

Status: Enrolling

Conditions: Wound Infection

Treatments: Device: antibacterial bone traction needles

Study type: Interventional

Funder types: Other

Identifiers

NCT05735470

2021 0873

Details and patient eligibility

About

The goal of this clinical trial is to test in wound infection. The main question it aims to answer is: Whether this antibacterial bone traction needle is safe and has a good effect on wound infection. Participants will be implanted with an antibacterial bone traction needles and the infection grade of wound after surgery will be observed. If there is a comparison group: Researchers will compare the control group without antibacterial ability to see if the experimental group Can effectively inhibit wound infection.
