摘要：The introduction of surgical instruments into an animal body is effected, withouttissue incision, by migrating a specially constructed hollow needle into the body behind arotary augering tool journalled in the hollow needle. Surgical procedures may then beperformed with the rotary tool or the same may be withdrawn from the in situ needleand different surgical implements substituted therefor which may be extended beyondthe open end of the needle, as required. In the case of unwanted tissue removal, such asblood clots, cataracts and the like; a rotary masticating tool may be brought to theoperative site by introduction through the hollow needle, the unwanted tissuemasticated or liquefied and the same withdrawn through the needle bore followingremoval of the masticating tool. Similarly, fluids may be injected into the body andwithdrawn therefrom, as required, through the hollow needle.
< P>The application of the foregoing procedures to cataract surgery makes itpossible to remove a cataract while leaving the lens capsule in place. Following removalof the cataract and total contents of the lens capsule, the volume of removed material isthen replaced with a compatible lens filler material having a desired refractive index, suchas silicone, and the refractive property of the lens is retained obviating the usual massive
optical corrections previously associated with cataract surgery.
