Abstract

The invention discloses an opposite-side bent flute needle for retinal vitreous surgery. The device comprises a connecting rod, a driving mechanism, a transmission mechanism, a rotating mechanism, a needle tube, a hose and a connecting hole. The opposite-side bent flute needle for retinal vitreous surgery can help medical staff adjust the angle of the needle tube to be within the required range, so that the end opening of the needle tube can be firmly attached to the dead corner of the treatment part of the patient, hydrops at the dead corner of the treatment part of the patient are sucked bythe device, and the treatment effect of the patient is effectively improved.

Description

technical field [0001] The present invention relates to a needle for medical surgery, in particular to a contralateral curved flute needle for retinal vitreous surgery. Background technique [0002] With the popularization of modern vitreoretinal surgical techniques, a large number of blind patients due to retinal detachment can be treated in a timely and effective manner. However, in the actual surgical process, for patients with retinal detachment caused by peripheral retinal holes, it is difficult for medical workers to use traditional straight flute needles for retinal reattachment during surgery. The retrieval authorization announcement number CN202051899U discloses a contralateral curved seedling needle for retinal vitreous surgery, including a hollow needle tube, a screw bayonet, a silicone tube and a needle handle, and this patent has solved the above problems. [0003] However, the above-mentioned patent still has certain deficiencies. The deficiencies are: the hol...
