Description
Technical Field
The present invention relates to a fixing device, and more particularly to an optical fiber holding device for use in endoscopic surgery.
Background
The endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics and software, and is widely applied to minimally invasive surgery.
Optical fibers play an important role as light transmission means in the technology of endoscopes, especially medical endoscopes. In existing endoscopic devices, optical fibers are typically used to direct light from a light source into the distal end of the endoscope for providing illumination during the procedure.
In a medical environment, it is desirable to adequately sterilize medical equipment after use to facilitate subsequent use. Therefore, in order to facilitate sufficient sterilization of the medical endoscope apparatus, the medical endoscope apparatus is generally designed to be easily disassembled. Therefore, the optical fiber is installed in the endoscope device separately each time the endoscope device is used, that is, one end of the optical fiber penetrates into the endoscope device from the rear end of the endoscope device along the reserved channel, and the front end of the optical fiber penetrates out from the front end of the endoscope device, so as to realize the functions of light guiding and illumination. An endoscope fiber holding element is disposed inside the channel for holding a relative position between the optical fiber and the endoscope device by providing a certain frictional force.
To further facilitate the light-conducting connection between the light source and the endoscopic device and to facilitate maintenance and readiness of the fiber tip, the optical fibers used with the endoscopic device are generally reserved for a relatively large fiber length. In practice, the light source is not located a significant distance from the endoscopic device, and these excess lengths of optical fiber are typically coiled into a fiber bundle disk that is placed between the light source and the endoscopic device. When the endoscope apparatus is subjected to a positional change, the end portion of the optical fiber extending from the front end of the endoscope apparatus is affected by the excess optical fiber wound around the outside of the endoscope apparatus, and thus, a completely synchronous movement with the endoscope apparatus cannot be achieved. When a doctor operates the endoscope device, relative movement between the optical fiber and the endoscope device is easily caused along with the movement of the endoscope device in the forms of forward and backward movement, rotation, shaking and the like, and particularly, the end part of the optical fiber is easily caused to rotate at the front end of the endoscope device, so that the change of an illumination position is caused, and the operation is influenced.
To solve this problem, when using the endoscope apparatus, a doctor usually uses an adhesive material such as an adhesive tape, an adhesive note, etc. which is easily available in a hospital, to adhere the optical fiber adjacent to the endoscope apparatus to a fixed position relative to a patient, such as a surgical gown, an operating table, a support of other equipment, etc. of the patient, so as to separate the movement of the optical fiber tip from the optical fiber bundle disk, thereby reducing the influence of the optical fiber bundle disk on the movement of the optical fiber tip.
However, since the adhesive material completely fixes the optical fiber at a certain position, dynamic adjustment between the end of the optical fiber and the position where the optical fiber is adhered cannot be achieved. If the length of the free optical fiber reserved between the sticking position and the endoscope device is too long, the effect of avoiding the rotation of the optical fiber head is difficult to realize. If the length of the reserved free optical fiber between the sticking position and the endoscope equipment is too short and the movement of the endoscope is larger in the operation process, the optical fiber is easy to slide or fall off from the endoscope holding element, and the illumination effect of the optical fiber end and the normal operation of the operation are seriously influenced.
Therefore, based on the above problem that prior art exists, the utility model aims to provide an optic fibre holding device, can be convenient general relative position between optic fibre and the patient is fixed, can conveniently adjust the real-time of reserving free optic fibre length again in operation process, effectively avoids the relative motion between optic fibre and the endoscope equipment, simplifies operation process, is showing reliability and the security that improves the operation, improves operation efficiency.
