Description

Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a corneal flap separator. Background Art

[0002] During femtosecond laser surgery, due to laser energy barriers and other reasons, the corneal tissue separation is sometimes incomplete, forming an island-shaped or irregular "pedicle". If the "pedicle" cannot be separated intact and smoothly, the operation will not be able to proceed. In order to solve this problem, a special instrument is needed to effectively deal with this complication to ensure the success of the operation and the safety of the patient.

[0003] After searching, a utility model with announcement number CN209187185U discloses a corneal flap separator, including a handle and an operating piece, one end of the operating piece is connected to the handle, and the other end is an operating area at an obtuse angle to the handle, a concave notch is provided on the operating area, and both sides of the concave notch are double-sided blades. When in use, the handle is held in the hand, and the double-sided blades on the concave notch are used to remove corneal tissue. Through the design of the concave notch and the double-sided blades on the operating area, damage to the surrounding normal corneal tissue can be avoided during the operation, the occurrence of secondary complications can be avoided, and the success rate of the operation is improved.

[0004] The above-mentioned corneal flap separator still has some shortcomings in actual use:

[0005] 1. The angles of the operating part and the operating area of ​​the corneal flap separator are relatively fixed, and it is difficult to adjust the angle according to the needs of use, and the use is not flexible enough. Utility Model Content

[0006] The utility model aims to provide a corneal flap separator in order to solve the disadvantages in the prior art that the angles between the operating member and the operating area are relatively fixed and difficult to adjust according to the needs of use.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A corneal flap separator comprises a handle, one end of which is fixedly connected to a connecting rod, one end of which is fixedly connected to two connecting heads, an operating member is arranged between the two connecting heads, both sides of the operating member are fixedly connected to rotating shafts, and the two rotating shafts are rotatably connected to the two connecting heads respectively;

[0009] It also includes a limiting component, which is located between the connecting rod and the operating member. The limiting component can limit the rotation angle of the operating member in the connecting rod.

[0010] In a possible design, the limiting component includes a bidirectional screw rod rotatably connected between two connecting heads, one of the connecting heads is provided with a limiting hole, and one end of the bidirectional screw rod is rotationally limited by the limiting hole, one end of the operating member is fixedly connected with a limiting ring, and the bidirectional screw rod passes through the limiting ring, and the positive and negative threaded sections of the bidirectional screw rod are correspondingly provided with a first nut and a second nut on the threaded sleeve, and the first nut and the second nut are divided into two sides located on the limiting ring, and the first nut and the second nut are adjusted to move toward each other by rotating the bidirectional screw rod, and the first nut and the second nut are fixedly connected to the side away from each other with two through columns, and the two connecting heads are close to each other with two through grooves, and the two through columns slide through the through grooves correspondingly, and the movement of the first nut and the second nut can be limited by the through column.

[0011] In a possible design, one end of the bidirectional screw is fixedly connected to a rotating handle, one side of the other connecting head is provided with a first limiting groove, and the rotating handle is rotatably connected in the first limiting groove.

[0012] In a possible design, a suction cup is fixedly mounted on the other side of the handle to facilitate vertical placement of the separator.

[0013] In a possible design, the outer wall of the handle is provided with anti-slip grooves for easy handholding.

[0014] In a possible design, two blades are fixedly mounted on the operating member.

[0015] In the present application, when the rotation angle of the operating member needs to be adjusted, the bidirectional screw rod is rotated. Since the bidirectional screw rod has positive and negative thread segments, the first nut and the second nut of the clamping part will move closer to or farther from each other. When the first nut and the second nut of the clamping part are close to each other, they will clamp the limiting ring on the operating member, thereby limiting its rotation. When the operating member needs to be released, the bidirectional screw rod is rotated in the opposite direction to move the first nut and the second nut of the clamping part away from each other, thereby realizing the free rotation of the operable member. At the same time, the suction cup at one end of the handle can be adsorbed and placed on the desktop.

[0016] Beneficial effects:

[0017] In the utility model, the corneal flap separator can realize accurate control of the rotation angle of the operating member by limiting the accurate adjustment of the components, thereby ensuring more flexible use of the separator during surgery;

[0018] In the utility model, the corneal flap separator, the first nut and the second nut of the clamping part can stably clamp the operating part through the cooperation of the through column and the through groove, thereby preventing the operating part from accidentally rotating during the operation, thereby improving the stability and safety of the operation;

[0019] In the utility model, the corneal flap separator can adapt to different surgical needs by adjusting the rotation angle of the operating part, and has strong adaptability and flexibility. The entire corneal flap separator is reasonably designed and has a stable and reliable structure. The safety and reliability of the surgical process are ensured through precise adjustment and stable clamping. BRIEF DESCRIPTION OF THE DRAWINGS
