Embodiment 1

[0029] A lens separator for full femtosecond microsurgery, such as figure 1 , 2 As shown, it is composed of a separation shovel 1, a handle 2 and an incision hook 4. The separation shovel and the incision hook are coaxially fixed or integrated at both ends of the handle. The direction of the separation shovel and the incision hook is opposite; There are anti-skid lines 3 to prevent slippage of the instrument during the operation and make the operation safer.

[0030] The structure of the separation shovel is as follows figure 2 , 3 , 4, 6, and 7, it is made by integrally connecting the straight bar section c, the arc section b and the round shovel section a, wherein the lower end of the straight bar section is coaxially fixed with the upper end of the handle, or it is made in one body, and its The cross-section is circular; with the extension of the upper part of the straight rod section, the diameter of the cross-section gradually becomes smaller, and turns after about 1....

Embodiment 2

[0037] A lens separator for full femtosecond microsurgery, see Figure 8 , 9 , 10, 11, 12. Its external structure also includes incision hook, handle and separation shovel, and the structure of the separation shovel 5 of the present embodiment is different from that of embodiment 1. Only the structure of the separation shovel is described below:

[0038] Such as Figure 8 , 9 As shown, the separation shovel includes a straight bar section, an arc section and a circular shovel section, but there is also a turning section f between the straight bar section and the arc section. The segment and the arc segment are reversed at an acute angle.

[0039] For the cross-sectional shapes of the straight bar section, between the turning section and the arc section, and the arc section, refer to Figure 10 , Figure 11 , Figure 12 .. The specific structure is described as follows:

[0040] The straight rod section is the direct continuation or fixed installation of the handle, a...

Abstract

The invention relates to a lens separator for all-femtosecond microsurgery, which comprises a separating shovel, a handle and an incision hook. The separating shovel and the incision hook are coaxially fixedly mounted at two ends of the handle; the separating shovel consists of a straight rod section, an arc section and a round shovel section which are integrally connected, the lower end of the straight rod section and the upper end of the handle are coaxially fixedly mounted, the diameter of the upper portion of the straight rod section is gradually reduced while the upper portion of the straight rod section turns and is connected with the arc section, an included angle between the straight rod section and the arc section is an obtuse angle, the cross section of the arc section is in the shape of a flat ellipse, the other end of the arc section is thinned gradually, the taper of the other end of the arc section is gradually reduced, furthermore, the terminal of the other end of the arc section is connected with the round shovel section with a circular tip, and the center of the cross section of the round shovel section is thick while the periphery of the cross section of the round shovel section is thin; and the incision hook comprises a straight rod section and a bent tip section. Surgery can be safer and smooth by the lens separator for all-femtosecond microsurgery, a matrix lens can be thoroughly separated, side effects including that the matrix lens is damaged, remained and the like in a separation process are reduced, the lens separator is favorable for completely taking out the matrix lens, simultaneously, injury to cornea tissues of a patient due to repeated operation is relieved, and postoperation recovery of wound is benefited.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to microsurgical instruments related to corneal refractive surgery, in particular to a lens separator for full femtosecond microsurgery. Background technique [0002] In recent years, corneal refractive surgery has gone through different stages of development, and many new technologies and treatments have emerged. As a new technology and concept, femtosecond laser was approved by the US FDA for corneal refractive surgery in 2000. Based on its precise cutting characteristics, full femtosecond surgery is a new surgical method with good safety, Efficiency, predictability and stability come into focus. The principle of the operation is that the femtosecond laser is precisely focused on the preset corneal stroma plane through a non-applanation cone lens, and the posterior and anterior surfaces of the stroma lens are scanned sequentially, and then the edge cutting of the lens and the cor...
