Novel reverse capsulorhexis forceps type crystalline lens nucleus treatment forceps

Abstract

The invention discloses a pair of novel reverse capsulorhexis forceps type crystalline lens nucleus treatment forceps, and relates to the technical field of cataract removal surgery, in particular to a pair of novel reverse capsulorhexis forceps type crystalline lens nucleus treatment forceps which comprises two forceps bag forceps handle pieces, one end of each forceps bag forceps handle piece is provided with a detachable mechanism, and the other end of each forceps bag forceps handle piece is provided with a positioning clamping piece. And the positioning clamping piece is welded and fixed on the forceps bag and the forceps handle piece. The nucleus pre-chopping piece can be used for pre-chopping a nucleus, the reverse hook of the nucleus pre-chopping piece can stretch into the position below a crystal nucleus to hook a crystal nucleus block out of an eye from an incision, the surgical incision can be reduced, intraoperative complications are reduced, and the healing and recovery effects are improved; by means of the sawtooth-shaped structure of the teeth, the friction force between the hooked crystal nucleus block and the reverse tweezers bag clamp can be increased, the convenience of hooking the crystal nucleus block can be improved, the tweezers bag clamp handle pieces can be separated by a certain distance through the pin shaft, and the phenomenon that the tweezers bag clamp handle pieces deform due to the fact that force is applied between the tweezers bag clamp handle pieces is too large can be avoided.

Description

Technical field [0001] The present invention relates to the field of cataract removal surgery techniques, specifically a new type of reverse tear-off tweezers lens nuclear treatment tweezers. Background [0002] A key step in the cataract removal process is to remove the lens nucleus (especially the hard core) from the lens capsule, and now the mainstream method is cataract ultrasonic emulsification suction, that is, the use of ultrasound to emulsify and aspirate the lens nucleus (crystal nucleus opacification is cataract). However, ultrasonic emulsification instruments are expensive, the surgical cost is high, and the surgical learning curve is longer, which cannot be fully popularized; so in relatively remote areas, the traditional small incision cataract extraction is still widely used, that is, through instrumental manipulation of the nucleus or manual delivery of the nucleus, however, whether it is conventional ultrasound emulsified cataract aspiration or traditional small i...

AI Technical Summary

Problems solved by technology

However, the phacoemulsification equipment is expensive, the operation cost is high, and the operation learning curve is long, so it cannot be fully popularized; therefore, in relatively remote areas, the traditional small incision cataract extraction is still widely used, that is, by means of nuclear fragmentation or However, regardless of conventional phacoemulsification cataract extraction or traditional small incision cataract extraction, in order to reduce surgical complications and improve surgical safety and convenience, different nuclear treatment methods can be selected, including pre-chopping nucleus technology, and the pre-chopping technology is to use various pre-chopping instruments to cut into the lens nucleus and physically split it into small pieces, which is conducive to the removal of the nucleus and reduces the occurrence of complications. In order to meet the market demand , we provide a novel reverse capsulorhexis forceps lens nucleus handling forceps
