Clinical Application Of Three-dimensional Visualization In Precise Resection Of Bone And Soft Tissue Tumors

Objective: To study the application of three-dimensional visualization technology in the surgical resection of bone and soft tissue tumors.To explore the virtual imaging effect of 3D visualization technology on the anatomy of patients,the accuracy of preoperative assistant operator’s assessment of patient’s condition and surgical formulation,and the accuracy of actual resection operation under the guidance of visualization technology.To explore the diagnosis and treatment of bone and soft tissue tumor patients in the digital era.Methods:Twenty-eight patients with bone and soft tissue tumors who underwent surgical resection in the bone and soft tissue repair and reconstruction surgery of the Second Affiliated Hospital of Dalian Medical University were collected,including 14patients in the observation group and 14 patients in the control group.After the patients in the observation group completed the preoperative CT,MRI and other examinations,all their image data were imported into the 3D visualization auxiliary diagnosis system of Heilongjiang Tuolung Technology,and the 3D virtual models of the tumor and its surrounding blood vessels,nerves and other important tissues were reconstructed.After the reconstruction virtual models were combined with the patient’s condition and fully considered,the corresponding surgical planning was made.Among them,operations with special anatomical structures or complex relationships around the tumor can be guided by Holo Lens glasses to assist in dynamic positioning during operation.In the control group,14 patients completed preoperative preparation and made surgical plan through traditional imaging examination,and underwent surgical resection of tumor.The intraoperative bleeding volume,drainage volume on the first day after operation,and the maximum diameter of the tumor measured before operation and actually removed during operation in the observation group were collected and analyzed.Results: The 3D visualization aided diagnosis system can successfully reconstruct the3 D virtual model of tumor and its adjacent tissue structure in 14 patients with bone and soft tissue tumors.During the operation,the intraoperative blood loss in the observation group was 36.57 ± 32.66 ml,and the intraoperative blood loss in the control group was100.71 ± 49.35 ml.The intraoperative blood loss in the observation group was significantly lower than that in the control group(P=0.0006<0.05,with significant difference);The drainage volume of the observation group was 10.71 ml ± 12.80 ml on the first day after operation,while that of the control group was 43.36 ml ± 38.18 ml on the first day after operation.The drainage volume of the observation group on the first day after operation was significantly lower than that of the control group(P=0.0071<0.05,with significant difference);The maximum diameter of the pre-resected tumor in the observation group was 8.93 cm ± 4.90 cm measured by the three-dimensional visualization software before operation,and the maximum diameter of the actual resected tumor during operation was 9.71 cm ± 5.49 cm.The preoperative measurement was consistent with the maximum diameter of the actual resected tumor during operation.(P=0.6837>0.5,no significant difference).Through the comparison of the above data,it can be found that the size of the tumor and the anatomy around the tumor can be accurately presented by the 3D visualization technology to reconstruct the3 D three-dimensional model data before surgery;Compared with the control group,the observation group had more adequate preoperative preparation,more complete surgical plan formulation,less intraoperative trauma,and faster postoperative recovery.Conclusion: 1.Three-dimensional visualization technology can display the size,anatomical location and adjacent tissues of bone and soft tissue tumors in an all-round and three-dimensional way,help the operator understand the condition more accurately,optimize the formulation of surgical plan,and achieve the accuracy of tumors.Assisted hybrid reality technology can also project personalized virtual images of patients onto the patient’s body surface,realize the combination of virtual and real,avoid errors caused by body position changes,and achieve effective treatment while reducing intraoperative side injuries and postoperative complications.2.3D visualization technology can improve the efficiency of remote diagnosis and treatment and make full use of medical resources.Through preoperative virtual imaging,patients and family members can also have a more intuitive and full understanding of the condition and treatment plan,alleviate the anxiety of patients and family members,improve communication efficiency,and reduce doctor-patient disputes.It is helpful for preoperative conversation,surgical risk and surgical plan explanation.
