中文摘要 近年來,隨著寵物在人們生活中地位不斷提升,動物醫院的需求大幅提高,關於獸醫的職業危害也逐漸浮現。獸醫工作環境複雜多樣且工時過長,容易導致下背痛問題發生。大多數的下背痛患者被歸類為非特異性下背痛,這意味著腰痛本身沒有已知的病理解剖學原因,其原理與脊椎的壓力負荷有強烈之關聯性。
從獸醫手術期間的姿勢狀態著手,本研究結合了生物力學與生理解剖學觀點,系統化的將子宮卵巢摘除術過程分為三個階段進行手術行為分析,分別為:切腹壁、子宮摘除及縫合。系統裝置的設計發展分為兩個重要部分: (1) 兩階段的焦點團體法建立設計準則與設計發想, (2) 設計構想的特徵檢視,邀請獸醫進行討論以獲得使用性的相關評論,整合獸醫在進行手術時與動物間的關係。
本研究之評估方法始於獸醫手術期間的軀幹穩定性,考慮獸醫下背部、頸部、肩部及腕部的角度變化與體內的血流狀態。透過設計創新的評估方法來針對新的系統裝置進行實驗評估。結果顯示,本研究提出之上凸曲面有助於減少脊椎的力學負荷、肌肉過度拉伸並促進血液循環。此上凸曲面與影像輸出結合後,更有效改善獸醫在手術時過低視覺角度造成的職業傷害。故本研究發現減緩獸醫非特異性下背痛問題對於獸醫在工作品質及效率上產生有極重要的影響。
英文摘要 In recent years, with the growing number of domestic pets, the demand for animal hospitals has increased greatly, and the occupational hazards of veterinarians have gradually emerged. Veterinarians work in complex and varied environments for prolonged working hours, which easily lead to Low Back Pain (LBP). Most LBP patients are classified as Non-Specific Low Back Pain (NSLBP), which means that lumbago itself has no known pathological anatomy reason, and its principle is strongly related to the pressure load of spine.
Starting from the posture state during veterinary surgery, this study combines the views of biomechanics and physiological anatomy, and systematically divided the ovariohysterectomy process into three stages for surgical behavior analysis, namely, abdominal wall cutting, uterus removal and suture. The design and development of the system devices was divided into two important parts: (1) The two-stage focus group to establish design criteria and design concept, (2) The feature inspection of design concept, when veterinarians were invited for discussion to obtain relevant comments on usability, and the relationship between veterinarians and animals during the surgery was integrated.
The evaluation method of this study first examined the stability of the trunk during veterinary surgery, taking into account the angle changes of the veterinarian's lower back, neck, shoulder and wrist and the blood flow state in the body. Innovative evaluation methods for experimental evaluation of the new system devices. The results show that the Upper Convex Surface proposed in this study was helpful to reduce the mechanical load of the spine and muscle overstretch and promote blood flow. After Upper Convex Surface was combined with screen mirroring, it was more effective to improve occupational injuries caused by veterinarians' low visual angle during surgery. Therefore, this study found that mitigating the NSLBP problem of veterinarians has a very important impact on the work quality and efficiency of veterinarians.
