Clinical trials

Cartridges of Disposable Endoscopic Linear Cutting Staplers, Disposable Powered Endoscopic Linear Cutting Staplers and Disposable Endoscopic Linear Cutting Staplers manufactured by Ningbo Verykind Medical Device Co., Ltd. have marketed in many countries or area for many years. The investigational devices are intended for transection, resection, and/or creation of anastomoses. The instruments have application in multiple open or minimally invasive general, gynecologic, urologic and thoracic surgical procedures. In order to confirm the safety and performance of the products, as well as the continued safety and clinical performance of the implant (the staple) during the clinical follow-up period, monitor the identified side-effects, contraindications and identify previously unknown side-effects, and ensure the continued acceptability of the benefit-risk ratio, Investigators proactively collect and evaluate clinical data from different regions, including of Italy, Brazil and Chile, where the device has been marketed, and conduct PMCF studies.

This study conducted a Post-Market Clinical Follow-Up study (PMCF) to evaluate the safety and effectiveness of the disposable endoscopic linear cutter stapler produced by Changzhou Ankang Medical Instrument Co., Ltd., through a retrospective analysis of the clinical data, to evaluate the safety and effectiveness of soft tissue resection, transection and anastomosis.

This is a multi-center and retrospective cohort study to evaluate the efficacy and safety of disposable linear cutting staplers and components in soft tissue resection, transection and anastomosis.

The goal of this clinical trial is to use the investigational device (Zirconia Dental Ceramics) to perform dental prosthesis in Patients with permanent teeth. The main question it aims to answer is: Is the safety and efficacy of the investigational device (Zirconia Dental Ceramics) adequate to meet the requirements for clinical use? Participants will use the investigational device (Zirconia Dental Ceramics) to perform dental prosthesis and then complete a 12-month follow-up after prostheses. During the follow-up period，participants will assess their satisfaction，while the investigator will assess the efficacy indices of prosthesis survival rate, prosthesis success rate and prosthesis quality.

The objective of this clinical trial was to evaluate the safety and effectiveness of single-use annular sutures for the closure of annular incisions after nucleus pulposus removal. Participants used single-use annular sutures to close the annular fibers. The success rate of suture, reduction value of annulus, proportion of annulus reduction, intraoperative blood loss, suture time, VAS pain score (low back, bilateral lower extremities), Oswestry index (ODI index), and Short were evaluated The effectiveness evaluation results of Form-12 health survey (SF-12 score), treatment success rate, device defects, product operation satisfaction, and safety evaluation results of recurrence rate, adverse events, and serious adverse events were used to verify the safety and effectiveness of disposable fibrillar suture for annular incision suture after nucleus pulposus removal.
