[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1 As shown, in this embodiment, a multifunctional surgical forceps for ophthalmology is provided, comprising: a first forceps arm 11 , a second forceps arm 12 , a first end 13 , a second end 14 , a fixing portion 2 and a scraping portion 32 .

[0033] The first end of the first forceps arm 11 and the first end of the second forceps arm 12 are connected together. The first terminal 13 and the second terminal 14 are respectively formed on the second ends of the first forceps arm 11 and the second forceps arm 12, which are opposite to the first ends. The first end and the second end are defined according to the connection relationship between the first forceps arm 11 and the second forceps arm 12, but are not a limitation of the structure. The first end is the end where the first forceps arm 11 and the second forceps arm 12 are connected. Figure 1 The first tweezers arm 11 and the second tweezers arm 12 are shown as upper ends, and the second end is the lower end. The first end 13 and the second end 14 can swing relative to the first end to complete the clamping action.

[0034] The fixing part 2 is arranged on the first end 13 and / or the second end 14, and includes a fixing hole 21 of which the size can be adjusted. For example, the fixing part 2 can be arranged on any one of the first end 13 and the second end 14, or the first end 13 and the second end 14 are both provided with the fixing part 2. The size of the fixing hole 21 can be adjusted to accommodate the in vitro eyeballs of different sizes.

[0035] The scraping part 32 is arranged at the edge of the first end 13 and / or the edge of the second end 14, and is suitable for scraping animal tissue. For example, the scraping part 32 can be arranged on any one of the edge of the first end 13 and the edge of the second end 14, or the edge of the first end 13 and the edge of the second end 14 are both provided with the scraping part 32, and the scraping part 32 can be used for subsequent tissue scraping work of the ex vivo eyeball, and can be used to collect materials from the ex vivo eyeball when separating retinal pigment epithelial cells, which not only facilitates the operation of the experimenter, but also causes less damage to the retinal pigment epithelial cells, and there is no need to use other scraping instruments for operation.

[0036] When in use, the second end of the first forceps arm 11 and the second end of the second forceps arm 12 can move toward or away from each other with their respective first ends as the swing center, so as to clamp the animal's eyeball out of body. During the clamping process, the size of the fixing hole can be adjusted according to the size of the animal's eyeball, and then the fixing hole 21 of the first end 13 and / or the second end 14 is moved to contact the animal's eyeball, and then the first forceps arm 11 and the second forceps arm 12 drive the first end 13 and the second end 14 to clamp the animal's eyeball, and the fixing hole 21 can fit the surface of the animal's eyeball, so as to avoid displacement or rotation of the animal's eyeball, thereby facilitating the subsequent use of the puncture instrument to puncture the animal's eyeball, and the animal's eyeball will not be displaced or rotated during the puncture process, so as to facilitate the control of the puncture force, thereby ensuring that the puncture hole meets the preset size and preset position, improving the experimental efficiency, and ensuring the accuracy of the detection index.

[0037] In addition, when scraping the animal eyeball tissue in the subsequent process, the scraping part 32 can be directly used for scraping without setting up other additional instruments for scraping, thus realizing multiple functions of the same surgical forceps and reducing the experimental cost.

[0038] like Figure 1 As shown, in this embodiment, two fixing parts are respectively arranged on the first end 13 and the second end 14, and the two fixing holes 21 are arranged opposite to each other. The two fixing holes 21 can be used to fix the two relative surfaces of the ex vivo eyeball respectively, thereby further avoiding the rotation or displacement of the ex vivo eyeball.

[0039] like Figure 1 As shown, in this embodiment, the first end 13 is in an arc shape and has a width dimension greater than the width dimension of the first forceps arm 11. A tip 31 is formed at the end of the first end 13, and a scraping portion 32 is close to the tip. For example, as shown in the figure, the first end 13 is bent from the second end of the first forceps arm 11 and extends a certain length, and has an inner arc surface and an outer arc surface between the first forceps arm 11. There is a plane between the edge of the outer arc surface and the end of the first end 13, and the plane is the scraping portion 32. The connection between the plane and the inner arc surface is the tip 31. The tip 31 can be used for sampling and tissue separation of the contents of the eyeball, and it is not easy to damage the tissue, such as picking the lens. The setting of the tip 31 further improves the functionality of the multifunctional surgical forceps provided in this embodiment, and it is more flexible and convenient to use.

[0040] The second end head 14 has the same shape as the first end head 13 , and also has a pointed end 31 and a scraping portion 32 .

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the fixing part 2 includes: a shell and a plurality of blades 22. A circular through hole 211 is opened in the middle of the shell. The plurality of blades 22 are arranged in the shell through a rotating structure, and the plurality of blades 22 are arranged around the circular through hole 211, and are suitable for synchronously moving toward or away from the center of the circular through hole 211, and one end of the plurality of blades 22 close to the center of the circular through hole 211 together forms the fixing hole 21. For example, the plurality of blades 22 can rotate clockwise or counterclockwise around the center of the circular through hole 211 together. When the plurality of blades 22 move clockwise around the center of the circular through hole 211, the plurality of blades 22 can move toward the direction close to the center of the circle while changing the circumferential direction position, thereby reducing the fixing hole 21. When the plurality of blades 22 move counterclockwise around the center of the circular through hole 211, the plurality of blades 22 can move toward the direction away from the center of the circle while changing the circumferential direction position, thereby increasing the fixing hole 21.

[0042] With such arrangement, the size of the fixing hole 21 can be flexibly adjusted according to the size of the isolated eyeball, and the specific design parameters can be determined according to the actual situation.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the shell includes an upper shell 23 and a lower shell 24 that are snapped together, a first guide groove 221 is provided on the end surface of the blade 22 facing the upper shell 23, a first protrusion 222 is provided on the end surface of the blade 22 facing the lower shell 24, the upper shell 23 is provided with a plurality of second protrusions 231, and the plurality of second protrusions 231 respectively extend into the corresponding first guide grooves 221, the lower shell 24 is provided with a plurality of second guide grooves 242, and the plurality of first protrusions 222 respectively extend into the corresponding second guide grooves 242, wherein the plurality of second guide grooves 242 are obliquely arranged around the circular through hole 211, and after the first protrusions 222 of the plurality of blades 22 extend into the corresponding second guide grooves 242, the first guide grooves 221 of the plurality of blades 22 obliquely surround the circular through hole 221.

[0044] For example Figure 3 As shown in , a plurality of second guide grooves 242 are arranged around the circular through hole 211, and the second guide grooves 242 extend from the side of the lower shell 24 away from the circular through hole 211 to the side close to the circular through hole 211. In this way, the first protrusion 222 of the blade 22 can move along the second guide groove 242 toward or away from the center of the circular through hole 211. After the plurality of blades 22 are installed in place, the plurality of first guide grooves 221 are also arranged in the same principle as the second guide grooves 242. The first guide grooves 221 extend from the side away from the circular through hole 211 to the side close to the circular through hole 211. In this way, when the second protrusion 231 of the upper shell 23 rotates around the center of the circular through hole 211, the side wall of the first guide groove 221 can push the blade 22 to rotate around the center of the circular through hole 211. That is, the blade 22 can be driven to rotate by rotating the upper shell 23, thereby realizing the control of the size change of the fixing hole 21, and the operation is simple.

[0045] like Figure 3 and Figure 4As shown, in this embodiment, a limiting member 241 is provided on the end face edge of the lower shell 24 facing the upper shell 23, and the upper shell 23 is provided with an arc groove 232 matched with the limiting member 241. The arc groove 232 is concentrically arranged with the circular through hole 211, and the two edges in the extending direction of the arc groove respectively have a first retaining wall and a second retaining wall. The upper shell 23 can rotate around the center of the circular through hole 211 through the cooperation of the arc groove 232 and the limiting member 241, and when the inner walls at both ends of the extending direction of the arc groove 232 contact the limiting member 241, the arc groove 232 can be limited, thereby setting the maximum rotation angle of the upper shell 23 relative to the lower shell 24, thereby reasonably setting the extension length of the blade 22 to control the limit size of the fixing hole 21.

[0046] like Figure 3 and Figure 4 As shown, in this embodiment, a plurality of stoppers 241 are arranged at intervals on the edge of the end surface of the lower housing 24, and a plurality of arc grooves 232 are arranged at intervals on the edge of the upper housing 23. For example, as shown in the figure, four stoppers 241 are arranged on the lower housing 241, and the four stoppers 241 have the same radial size of the circumference of the lower housing 241, and the four arc grooves 232 are arranged on the edge of the upper housing 23 in the same manner, thereby increasing the stability of the rotation of the upper housing 23.

[0047] like Figure 1 As shown, in the present embodiment, the scraping portion 32 has a blade, thereby making it easier for the scraping portion 32 to scrape animal tissue.

[0048] like Figure 1 As shown, in this embodiment, an anti-skid portion 41 is provided in the middle of the first forceps arm 11 and the second forceps arm 12. The anti-skid portion 41 may be an anti-skid pattern or a frosted surface to prevent skidding and facilitate the operator to use the multifunctional surgical pinch for operation more conveniently.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
