Description
Technical Field
The invention relates to a surgical suture and an optical fiber sensing technology, in particular to an intelligent surgical suture based on an optical fiber sensor and a structure construction method thereof.
Background
The suture may provide permanent or temporary tension for the healing of the incision during surgery. During the operation suture process, the tightness of the suture has important influence on the postoperative healing. If too loose, would affect the healing of the incision; if too tight, discomfort to the patient may result. At present, the surgical suture mainly depends on the experience of doctors, and the postoperative healing is influenced by great difference among different doctors. The tension of the suture is also related to the stage of healing of the incision, which is gradually decreasing as the incision heals. Therefore, if the tension of the suture thread can be known, the degree of healing of the incision can be determined. Similarly, the temperature of the incision can be used to determine whether the incision is infected.
To date, however, there is still no effective method of measuring suture tension and temperature. The only intelligent surgical suture in the world at present was invented by professor John Rogers (John Rogers) in materials science and engineering at champagne division, university of illinois. The surgical suture is wrapped with a sensor that monitors the wound, as shown in fig. 1. The electronic suture contains high molecular polymer or silk thread and is integrated with an ultrathin silicon sensor to measure the temperature. The disadvantage of this suture is that the exterior of the traditional suture is covered with new material, thus presenting a great challenge to how to achieve proper suture function. Also, the sensor can only measure temperature and not tension of the suture.
Compared with the traditional electrical sensor, the optical fiber sensor has many advantages, such as simple structure, small volume, high sensitivity, electric insulation, acid and alkali corrosion resistance, strong anti-electromagnetic interference capability, distributed real-time online detection, small interference to the detected substance and the like. Optical fiber sensors can be divided into two categories according to their sensing principles: one type is a light-transmitting sensor and the other type is a sensor of the sensing type. The main applications in medicine are light-transmitting optical fiber sensors. Medical image transmission is a very distinctive part of the application of transmission-type optical fiber sensors, for example, since the introduction of optical fibers into endoscopes, the scope of application of endoscopes is expanded not only for diagnosis but also entering the field of treatment.
