Description
The technical field is as follows:
the utility model relates to the technical field of medical equipment, especially, relate to a functional artificial crystal navigator auxiliary device.
Background art:
the artificial lens navigator is a necessary product for combining cataract surgery with astigmatic artificial lens implantation or corneal astigmatism relaxing surgery, and the accuracy of marking directly influences the astigmatic correction effect.
The navigator assistance device is needed for marking. However, the conventional navigator auxiliary device has a complex structure, is inconvenient to use, and needs an operator to continuously adjust the position, thereby affecting the marking accuracy.
The utility model has the following contents:
the utility model aims at the defects of the prior art and provides a functional artificial crystal navigator auxiliary device with simple structure and convenient operation and accurate positioning.
The utility model discloses a realize through following technical scheme: the utility model provides a functional artificial crystal navigator auxiliary device, includes handle portion, connecting rod portion and arc mark portion, connecting rod portion sets up on handle portion, arc mark portion sets up in connecting rod portion, and arc mark portion both ends have respectively presses the sword, and two pressure sword are not located same water flat line.
In a preferred embodiment of the present invention, the connecting rod portion includes an integrally formed straight line section and a curved section, the straight line section is connected to the handle portion, and the curved section is connected to the arc-shaped marking portion.
For convenience of operation, the arc-shaped mark part and the straight line segment preferably have two different types of 30-degree included angle or 90-degree included angle.
In a preferred embodiment of the present invention, the arc length of the arc-shaped mark portion is about 11 mm.
In a preferred embodiment of the present invention, the radius of curvature of the pressing blade is about 7.5 mm.
Preferably, an inwardly concave circular arc-shaped hollow-out portion is arranged between the two pressing blades.
The utility model has the advantages that: this functional artificial lens navigator auxiliary device can guide astigmatism type intraocular lens axle position in the art unanimous with target cornea axle position, can be applied to accurate the pine of cornea in cornea astigmatism incision Art (AK) art, and the arc mark portion that the slope set up has improved the convenience of operation greatly, and its processing cost is low, and the location is accurate, and convenient to use has improved the quality and the efficiency of operation.
Description of the drawings:
FIG. 1 is a front view of the functional artificial crystal navigator support apparatus of the present invention;
FIG. 2 is a side view of the functional intraocular lens navigator assistance device of the present invention;
fig. 3 is a schematic structural diagram of the arc-shaped mark portion of the present invention.
The specific implementation mode is as follows:
the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
As shown in fig. 1 and 2, the functional artificial crystal navigator auxiliary device includes a handle portion 1, a link portion 2 and an arc-shaped mark portion 3, wherein the link portion 2 is disposed on the handle portion 1, and the arc-shaped mark portion 3 is disposed on the link portion 2.
The connecting rod part 2 comprises a straight line segment and a bent segment 21 which are integrally formed, the straight line segment is connected with the handle part 1, and the bent segment 21 is connected with the arc-shaped marking part 3. The arc-shaped mark part 3 and the straight line segment form a 30-degree included angle, so that a 30-degree arc-shaped pressed film is formed and is used for corneal astigmatism of which the astigmatism axis before operation is near the horizontal meridian, and therefore the axis of the astigmatism type intraocular lens during operation is guided to be consistent with the target cornea axis.
The arc mark part 3 can form a 90-degree left-right included angle with the straight line segment, and the 90-degree included angle arc pressed film is used for corneal astigmatism of the preoperative astigmatism axis near the vertical meridian under the assistance of the narrow light band of the slit lamp microscope.
As shown in fig. 3, the arc-shaped mark portion 3 has a crescent-shaped structure, the arc length of the arc-shaped mark portion 3 is about 11mm, the pressing blades 31 are respectively arranged at two ends of the arc-shaped mark portion 3, and the curvature radius of the pressing blades 31 is about 7.5mm and the length is 3 mm. An inwardly concave circular arc-shaped hollow-out part 32 is arranged between the two pressing blades 31, and the length of the circular arc-shaped hollow-out part 32 is about 5 mm.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "side", "end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In addition, in the description of the embodiments of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "disposed," "provided," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Finally, it should be noted that: the above embodiments are only specific embodiments of the present invention, and are not intended to limit the technical solution of the present invention, and the protection scope of the present invention is not limited thereto, although the present invention is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: those skilled in the art can still modify or easily conceive of changes in the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
