In cleft palate surgery, the environment is especially critical when suturing. Encum-bered, obstructive space in the environment can hinder a suture while using the Dingman mouth gag. We introduced a novel but simple draping technique. A simple hand towel is placed over the gag. A hole is cut out in the middle according to each patient's mouth. After making the hole, the hand towel is soaked in water and gently squeezed. Then the towel is properly placed over the Dingman mouth gag. Dripping water on the hand towel during the suture helps keep it in place. Using this draping technique, we cut 14 minutes of operation time compared to the average operation time of the past 2 years. There were several disadvantages in previous draping method. First, long suture material may easily get caught. Second, the operation field can easily be contaminated. Third, focusing on the operation becomes difficult due to the obstruction. This draping technique can compensate for the disadvantages of the previous Dingman mouth gag.

Disposable nonwovens entered the medical field over four decades ago, beginning with basic paperlike face masks and proceeding through sterilization wrap, specialty drapes and gowns. These medical nonwovens have proven to be invaluable in products ranging from drape sheets to surgical gowns to adult pads and underpads by utilizing a gamut of nonwoven structures. The combining of nonwoven technologies has enabled the industry to offer products with properties hitherto though impossible.(omitted)

This paper proposes a method to estimate vertical interaction force to the end of the surgical instrument by measuring reaction force at the part supporting the trocar. Relation between the force to the trocar and the interaction force is derived using the beam theory. The vertical interaction force is modeled as a function of the reaction force to the trocar and the distance between the drape plate and the trocar. Experimental results show that error is induced by the asymmetric shape of the trocar tip because contact position between the instrument and the trocar tip is changed depending on the direction of the interaction force. The theoretical relation, therefore, is compensated and reduced. Average $L_2$ relative error of the estimated force in the x-direction and the y-direction is 5.81 % and 5.99 %, respectively.

감염된 당뇨병성 족부궤양의 병실내 벽매립형 중앙 흡인 장치를 이용한 창상 밀봉관리로 빠른 창상의 호전을 얻을 수 있었다. 이 창상관리 방법은 빠른 창상의 호전 외에도 비용을 획기적으로 줄일 수 있으며 환자의 동통을 줄이고 병실내 세균 전파의 위험이 적으며 필요 인력 축소 등의 장점이 있으나 말기신장부전 환자에서의 적용은 추가의 연구가 필요할 것으로 사료된다.
