摘要:
It is disclosed herein an iris expansion ring for which a model utility application is filed. The iris expansion ring conjugates the functions of iris expansion and pupil dilation on patients which will be subjected to ophthalmic surgeries, such, for example, cataract and vitreoretinal surgeries, and also permits implantation and withdrawal with a single incision. By using the present device, it is possible to dispense with accessory incisions to the ocular globe as well as use of injector for its insertion. Additionally, it also has an alternated fitting structure and a thickness that makes the whole implantation process easier.

The devices and methods of the present invention provide a means to depress the sclera in such a fashion as to provide single point, multiple point, semicircular or 360° circumferential scleral tissue depression without the need for manual manipulation of the scleral depressor. The device comprises a shaped depressor for insertion between the sclera and the orbit of the eye and a holding means for positioning the depressor. In some embodiments the device can be integrated with a speculum. Use of the device eliminates the need to have a second person manipulate the depressor during the procedure and directly enables bimanual surgery.

A cannula is described having a housing, a first lumen, a second lumen, and a port capable of fluid communication with the first lumen. The second lumen configured to receive fluid from the first lumen and to direct the fluid to a surgical site. A light emitting diode light source is positionable within the housing and configured to direct light through the second lumen to the surgical site.

A speculum (10) is provided herein which includes first (12) and second (14) arms, each having a channel (20) formed thereon adapted to the shape of an eyelid. A hinge (16) connects the first and second arms which permits the first and second arms to selectively rotate about an axis of rotation. The selective rotation causes the first and second channels to selectively move closer and farther apart. First (26) and second (28) elements are respectively located on the first and second arms, with the first and second elements being configured to cooperatively retain the first and second arms in select rotational positions with interfering interengagement between the first and second elements limiting rotation of the first and second arms. A slot (40) is defined in the second arm to partially separate a first portion (42) of the second arm from a second portion (44) of the second arm with the first portion being displaceable away from the second portion. The second element is located on the first portion. Advantageously, with this arrangement, the first portion acts as a spring-loaded hinge which applies not only biasing force to the second element for retention, but also permits the second element to be separable from the first element. The subject invention provides a mechanical feature beyond the inherent memory of the material for operation of the speculum.

An eye contact device and assembly for stabilizing a human eye at a selected position in an external coordinate system is disclosed. The device includes an eye-contact member having an inner contact surface for contacting a front surface of an eye, and a vacuum port formed within the eye-contact member and communicating with the eye-contact member's contact surfaces, by which a negative pressure can be applied between the eye and the contact surface, to stabilize the position of the eye with respect to the device. The device, which is adapted to be biased against the patient's eye, to secure the device to the eye, may be pivotally coupled to a positioning arm, and may carry one or more beam-directing elements by which the position of the device in an external coordinate system can be determined.

A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a center opening that provides a wide view of the ocular chamber during the procedure.

In surgery of the vitreous body in an eyeball of a human body, a burden on and time of a surgeon is suppressed from being spent, a burden on the eyeball of a patient is greatly reduced, and further, the possibility of a complication after the surgery is also lessened. A holding apparatus 1, which is characterized in that it comprises eyelid opener portions 10a and 10b for pulling and opening upper and lower eyelids, a lens ring 30 for holding a surgical contact lens on the eyeball, and connecting portions 40a and 40b for connecting the eyelid opener portions 10a and 10b with the lens ring 30 of the surgical contact lens so that the surgical contact lens is held on the eyeball, is set on the eyeball of the patient, which makes it unnecessary to stitch of the lens ring 30 on the eyeball.

A surgical laser smoke plume evacuator includes an evacuator body (12) which is formed to a shape which is suitable for placement in normal use position substantially entirely around, and adjacent to, a tissue site upon which laser surgery is to be performed. The evacuator body has structure for removing smoke therethrough, a smoke exit portion in communication with, and extending from, the evacuator body. The smoke exit portion (14) is connectable to vacuum source, to thereby apply a vacuum to the evacuator body causing smoke which is created at a surgical site during surgery to be removed from the surgical site through the evacuator body, and the smoke exit portion.
