[0027] Example 1

[0028] like Figure 1-Figure 4 As shown;

[0029] A foreign body removal forceps comprises a main body 1.

[0030] After checking, the public (announcement) number: CN202123420620.5 discloses a nasal foreign body remover. This technology discloses "a nasal foreign body remover, including an upper tweezer, a lower tweezer is arranged below the upper tweezer, the lower tweezer is movably inserted inside the lower tweezer, and the upper tweezer is movably inserted inside the upper tweezer, and other technical contents, and discloses that the nasal foreign body remover can facilitate better adjustment of the length of the lower tweezer and the upper tweezer, so as to facilitate the removal of foreign bodies at different depths of the nasal cavity. At the same time, through the cooperation of the first rubber sleeve, the second rubber sleeve and the anti-slip teeth, it is not easy to cause damage to the nasal cavity, and the foreign body is not easy to fall when it is removed. ";

[0031] When the above-mentioned device is used to remove foreign objects from the patient's eye, there is a certain angle between the tweezers and the foreign objects in the eye. However, the ends of the general tweezers are an integrated fixed structure, which causes inconvenience to the doctor when removing the foreign objects from the patient's eye and is not conducive to the doctor's cleaning and removal. Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, an adjustment component 2 and an angle positioning component 3 are added to the present application document.

[0032] According to the above content, in order to be able to adjust the angle of the clamping plate 201 of the main body 1 so that the main body 1 can clamp foreign objects in the strict part, it also includes an adjustment component 2 installed at one end of the main body 1; the adjustment component 2 includes two clamping plates 201 rotatably connected in the main body 1, a gear 202 installed at one end of the clamping plate 201, and a rack 203 slidably connected in a slide groove opened on one side surface of the main body 1, the rack 203 is meshed with the gear 202, and a limiting rod 204 is slidably connected in the main body 1, one end of the limiting rod 204 passes through the main body 1, extends to one end of the main body 1, and is inserted into the socket opened on the surface of the gear 202, the convex rod on the outer surface of the limiting rod 204 is slidably connected in the slide groove opened on the surface of the main body 1, and extends to one side surface of the main body 1, and is connected to a push plate 205 set on one side surface of the main body 1.

[0033] In this embodiment: according to the position of the foreign body in the eye, the doctor adjusts the angle of the splint 201 after disinfection so that the splint 201 can be adjusted to a position that matches the foreign body, and the limit rod 204 is pushed by the elastic force of the spring 206 so that the limit rod 204 can be inserted into the socket opened on the surface of the gear 202 to limit the splint 201, fix the angle of the splint 201, and change the angle of the splint 201, so that the main body 1 can use the splint 201 to clamp foreign bodies at different positions of the eye.

[0034] In an optional embodiment: the push plate 205 is slidably connected to the surface of the main body 1, and the surface of the push plate 205 is provided with anti-slip grooves.

[0035] In this embodiment, it is convenient to control the position of the limit rod 204. After the angle of the clamping plate 201 is adjusted, the gear 202 is fixed by the limit rod 204, so as to determine the angle of the clamping plate 201 and fix the clamping plate 201 at the specified angle.

[0036] In an optional embodiment: a spring 206 is sleeved on one end of the limiting rod 204 , one end of the spring 206 abuts against a convex rod on the surface of the limiting rod 204 , and the other end of the spring 206 abuts against the main body 1 .

[0037] In this embodiment, the spring 206 can push the limiting rod 204 to be inserted into the gear 202, thereby fixing the gear 202 and the clamping plate 201 and facilitating the movement of the limiting rod 204.

[0038] In an optional embodiment: two ribs 207 are symmetrically mounted on both side surfaces of the main body 1 .

[0039] In this embodiment, the structural strength of the end of the main body 1 is improved to prevent the portion of the main body 1 that contacts the clamping plate 201 from bending and deforming.

[0040] According to the above content, in order to control the clamping range of the main body 1 and prevent damage to the eyes due to excessive rebound force when clamping foreign objects in the eyes, it also includes an angle positioning component 3 installed at the other end of the main body 1. The angle positioning component 3 includes two positioning plates 301 installed on the surface of the main body 1 and a top plate 302 slidably connected to a slide groove on the surface of the positioning plate 301 and two extension rods 303 installed on one side of the top plate 302. A guide rod 304 is slidably connected in the extension rod 303. A clamping plate 305 with the same L-shaped structure is installed at one end of the two guide rods 304. The clamping plate 305 is inserted into the clamping groove on the surface of the main body 1, and the top plate 302 is slidably connected to the main body 1.

[0041] In this embodiment: when operating on the eyes, the main body 1 has a certain rebound force. If the rebound is too much, it is easy to cause damage to the patient's eyes. The clamping plate 305 can be pushed so that the clamping plate 305 can drive the top plate 302 to press against the surface of the main body 1, thereby determining the maximum clamping range of the main body 1, and the operation is more convenient.

[0042] In an optional embodiment: the top plate 302 is configured in an L-shape, and the L-shaped structure of the top plate 302 is chamfered.

[0043] In this embodiment, after the chamfered corner of the top plate 302 contacts the main body 1 , no jamming occurs, making the movement smoother.

[0044] The working principle and use process of the utility model are as follows: according to the position of the foreign body in the eye, the doctor adjusts the angle of the splint 201 after disinfection, so that the splint 201 can be adjusted to a position matching the foreign body, and the limit rod 204 is pushed by the elastic force of the spring 206, so that the limit rod 204 can be inserted into the jack provided on the surface of the gear 202 to limit the splint 201, and the angle of the splint 201 is fixed, so that the main body 1 can use the splint 201 to clamp the foreign body in the eye. When operating on the eye, the main body 1 has a certain resilience. If there is too much resilience, it is easy to cause damage to the patient's eyes. The card plate 305 can be pushed so that the card plate 305 can drive the top plate 302 to press against the surface of the main body 1, thereby determining the maximum clamping range of the main body 1, and the operation is more convenient.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
