Needle holding forceps

Abstract

The invention provides a pair of needle holding forceps, which relates to the technical field of medical instruments and comprises a first forceps arm and a second forceps arm, one end of the first forceps arm is fixedly connected with one end of the second forceps arm, and the other end of the first forceps arm and the other end of the second forceps arm can be close to each other or far away from each other. A needle holding structure used for clamping a suture needle is arranged at the other end of the first forceps arm, and a through hole corresponding to the needle holding structure is formed in the second forceps arm. When the front end of the first forceps arm and the front end of the second forceps arm are used for clamping, the needle tip part of the suture needle clamped by the needle holding structure can penetrate through the muscle belly bottom behind the muscle stopping end of the rectus ocularis and the through hole, the needle tip is pulled out, the suture is tightened, and the vessel forceps are fixed to an operation towel. Compared with the prior art, the pair of needle holding forceps provided by the invention can realize needle passing while clamping, avoids secondary injury caused by repeated attempts in a mode of firstly clamping the muscle stopping end of the rectus eye muscle by using a pair of toothed forceps and then passing the needle, and meanwhile, can prevent sclera from being punctured and reduce the surgical risk.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a needle-holding tweezers. Background technique [0002] At present, when performing eye surgery (such as modern extracapsular cataract extraction, glaucoma trabeculectomy, etc.), it is often necessary to fix the eyeball before it can be implemented. The existing method of eyeball fixation uses the superior rectus muscle to draw sutures. During operation, The operator needs to hold the toothed forceps in one hand, clamp the muscle end of the superior rectus muscle at the 12 o'clock position along the conjunctival surface and 8mm away from the limbus, and use the other hand to hold the suture needle with suture, behind the muscle end. The muscle belly is passed through, and then the sutures are tightened, and fixed on the surgical drape with vascular clamps.

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned ophthalmic surgery, local swelling was caused by local infiltration anesthesia at the place where the conjunctiva was to be clamped (below it is the muscle insertion end of the rectus oculi muscle). Holding the needle with one hand, the operation is more difficult. When the needle is too shallow, the needle will fail to pass; when the needle is too deep, the sclera may be pierced, and sometimes repeated attempts may be required, causing surgical risks such as local bleeding
