# Technology Behavior Model--Beyond Your Sight with Extended Reality in Surgery
## 5 Finding and Discussion  
XRU and XREU have a significant impact on the medical experts' use of XRSG for surgery. [PERSON] et al. [23] reiterated that the use of SG by surgeons in the application of spinal surgery can be effective in helping the surgeon to perform the procedure better and [PERSON] et al. [25] used SG in urological surgery. [PERSON] et al. [13] confirmed in their study that XR technology can help medical experts quickly and accurately locate patients' blood vessels and nerves and found that the usefulness and ease of use of XRSG had a significant positive impact on medical experts' behavior in using XRSG. For example, surgeons can use the XRSG to connect internal lenses to improve the visual clarity of the human eye through the AR system of eyeglasses, expanding the surgical field and facilitating the performance of surgery [47]. Therefore, H1 is supported and H2 support is confirmed. A wide and clear field of view can improve the efficiency of surgery, reduce the surgeon's work pressure, and reduce the operation time and the time affected by radiation. Thus, it reflects that users can easily use XR technology for clinical operations.  
On the other hand, IM is a 3D image based on the combination of XR technology and human system structure to simulate surgical practice and teaching. Due to the systematic and kinesthetic nature of the human body structure [48], the use of stereoscopic medical image composition can clearly show the internal structure of the human body. [PERSON] et al. [49] found that medical experts could locate the patient's blood vessels by image overlap and perform suturing during surgical vascular suturing. This demonstrated that the H3 hypothesis is feasible and that rapid localization simplifies the surgeon's search in favor of H4. ID has positive interactions with both XREU and XRU. It was found that the joint use of multiple interactive technologies can better serve the communication and usage switching of medical experts during surgery [10]. Good voice communication facilitates remote communication for surgery, and gesture recognition facilitates freeing the surgeon's hands. Eyeglass tracking facilitates switching and viewing of monitoring visualization data and images. Enhancing the utility and ease of use of the XRSG, the operator's behavior is subjective. Therefore, H5 and H6 are supported.  
From the above discussion, it is clear that the XRSG allows the surgeon to operate surgical instruments and instruments with both hands, avoid viewing multiple visual inspection displays, standardize operational actions, and avoid unintentional human errors; therefore, H7 and H8 are supported. The built-in high-definition camera of the XRSG can replace the human eye to enhance visual clarity and make the visual images larger [16]. In a study by [PERSON] et al. [50] medical experts used PicoLinker Smart Glasses to improve wire insertion under fluoroscopy. The wires were inserted exactly at the set position for ease of use. The use of the reflective SG is useful and reflects the ease of operation. Therefore, H9 and H10 are supported.  
The study shows that IM, ID, ON, and UP support perceived usefulness and ease of use, change the operating habits of medical experts during surgery, and have a positive behavioral impact on surgical operations. This demonstrates the feasibility of the proposed XR technology acceptance and behavioral theory.
