Fibre-optic epidural space catheter and the endoscope of epidural space catheter

Abstract

A optical fiber cavum epidurale pipe and an endoscope device thereof are disclosed. The optical fiber cavum epidurale pipe includes a cylindric protecting case, a pipe end output / input interface arranged at the end exterior of the protecting case, a optical fiber image part disposed in the protecting case, a infusion catheter and an illumination part. The optical fiber image part includes an image acquisition unit and an optical fiber image transmitting bind made of a plurality of optical fibers, wherein the optical fiber image transmitting bind adopts the same coordination borehole pattern for transmitting the image, and the allotype infusion catheter and the illumination part are positioned in the residual space occupied by the optical fiber image part in the case. The endoscope device of the cavum epidurale pipe not only includes the above cavum epidurale pipe, also includes an operating end output / input interface and an inner peeping processing unit. Thereby, the invention provides a medical appliance which can extending into the narrow part of the human body, have thin neck and flexibility, and can clearly position a pipe in the body of the patients directly by an image device and process the drug injecting operation.

Description

technical field [0001] The invention relates to an epidural catheter and an endoscope technology, in particular to an optical fiber epidural catheter and an endoscope device for an epidural catheter used in surgical anesthesia, and belongs to the technical field of medical instruments. Background technique [0002] At present, fiber optic endoscope is a commonly used image transmission system, and its transmission channel is composed of fiber optic bundles. The endoscopic technique of epidural catheter is the core content of minimally invasive surgery. It is not only suitable for epidural anesthesia, it can also be used for surgical analgesia, painless labor, diagnosis and treatment of spinal canal diseases, and epidural anesthesia. Diagnosis and treatment of intraspinal hemorrhage and tumors have been increasingly accepted by surgeons and patients. For example, the epidural catheter disclosed in Chinese Patent Application No. 200320128802.8 is one of them. The idea and be...

Problems solved by technology

[0006] First of all, since the infusion tube body 10 is cylindrical, the arrangement of at least one imaging optical fiber 20 arranged on the outer wall of the infusion tube body 10 is evenly distributed on its outer circumference; In the remaining space occupied by the infusion tube body 10, the shape of the cross-section of the optical fiber image transmission bundle and the number of unit fiber filaments required for high-definition image transmission cannot be guaranteed, and the softness of the fiber optic endoscope image transmission bundle will decrease. subject to many restrictions

[0007] Secondly, when the fiber optic endoscope used to detect the image of the object guides the needle tube of the puncture needle into the patient's body, the detected image is very blurred because there is no lighting fiber in the fiber optic endoscope structure.
