ZK optical fiber vitreous body cutting head

Abstract

The embodiment of the invention relates to a vitreous body cutting head with self-illumination optical fiber. The cutting head is characterized in that the main structure of the cutting head comprisesan insertion component, a cutting component, a handheld component and the optical fiber, and according to whether or not the cutting head comprises a cutting component internal optical fiber part, the cutting head is divided into a first type and a second type and used for the vitreous body cutting operation. According to the embodiment, the luminance of the periphery of the vitreous body cuttinghead can be improved, the defect of independent illumination optical fiber is overcome, accordingly, structures such as vitreous body and proliferative membrane on the periphery of the vitreous bodycutting head are precisely illuminated and recognized, the surgical operation is effectively guided, and accordingly the cutting position, time and degree are more precise. Meanwhile, the frequency that the surgical instruments enter and leave from surgical incisions repeatedly can be reduced, accordingly, the occurrence rate is lowered that the surgical instruments enter and leave from the eyes repeatedly and serious complications such as retinal dialysis and endophthalmitis are caused, and the after-operation reaction is reduced.

Description

technical field [0001] The invention relates to the field of medical and health care, in particular to a vitreous body cutting head (referred to as a glass cutting head) with an illuminating optical fiber. Background technique [0002] At present, none of the vitrectomy heads used in vitrectomy has an illumination system, and the illumination of the surgical field mainly depends on an independent light guide fiber, which needs to be inserted from another surgical incision for illumination. In the presence of the lens, the glass incision and light guide fiber cannot reach the position before the equator of the contralateral retina, so as not to damage the lens. Therefore, the position of the vitrectomy head and the optical fiber must be exchanged after the ipsilateral cutting is completed, so as to cut the remaining vitreous body and complete the operation. Although the optical fiber can play the role of panoramic lighting, due to the transparent nature of the vitreous body,...

AI Technical Summary

Problems solved by technology

Although the optical fiber can play the role of panoramic lighting, due to the transparent nature of the vitreous body, only the vitreous body within a certain range around the optical fiber head can be accurately identified. Due to the existence of the lens, the optical fiber cannot extend to the opposite side. The surrounding vitreous body at the lateral equatorial part and before the equatorial part cannot play the role of fine lighting, and the operator cannot accurately identify the position and quantity of the vitreous body here when performing vitrectomy, and can only rely on experience, or exchange light and the position of the vitrectomy head , after precise lighting with optical fiber and memorize the position of the vitreous body, then exchange the position of the optical fiber and vitrectomy head to complete the vitreous body cutting

[0003] The above-mentioned vitreous cutting head and lighting device cannot perform vitreous cutting around the entrance of the vitrifying head under precise lighting, so that the cutting operation cannot avoid blindness, thereby affecting the operation efficiency and postoperative effect, and in order to provide accurate lighting, the lighting has to be exchanged The light and the position of the vitrectomy head increase the number of surgical instruments entering and exiting the eye, prolong the operation time, increase the incidence of severe complications such as serrated margin separation and endophthalmitis, and reduce postoperative reactions
