DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0019] like Figures 1 to 5 As shown, the extraction forceps capable of injecting liquid medicine are used in the removal surgery of intraocular diseased tissue, polyps, residual membranes, etc., and the liquid medicine can be injected into the eye at the right time during use, without the need to remove it and then use a syringe to add medicine specifically, which reduces the frequency of surgical tools entering and exiting the eye, helps to prevent additional damage to intraocular tissue, thereby reducing the chance of complications, and helps to improve surgical efficiency. Specifically, it includes two relatively arranged fixed forceps 1, the two fixed forceps 1 are arranged in a V shape and the upper ends are fixedly connected, the lower ends of the two fixed forceps 1 are respectively fixedly connected to the forceps seat 2, and the two fixed forceps 1 cooperate with the forceps seat 2 to form the main supporting component of this embodiment.

[0020] A liquid medicine cylinder 3 is fixed between the two fixed forceps 1, and the lower end of the liquid medicine cylinder 3 extends into the forceps seat 2. The liquid medicine cylinder 3 is used to store the liquid medicine injected into the eye during surgery. A drug adding hole can be set through the liquid medicine cylinder 3. A rubber plug 4 is fixedly packaged in the drug adding hole, which is used to replenish the liquid medicine in the liquid medicine cylinder 3 after the rubber plug 4 is pierced by an injection needle. It is particularly suitable for intraocular surgery with a large amount of medicine. Since the rubber plug 4 has the characteristic of fast deformation speed, the hole formed after being pierced by the injection needle will automatically close, so it will not affect its sealing.

[0021] A forceps tube seat 5 is movably mounted between the forceps blade seat 2 and the liquid medicine cylinder 3. The forceps tube seat 5 can move up and down between the forceps blade seat 2 and the liquid medicine cylinder 3. Two relatively arranged tube seat push-out pieces 6 are connected to the sides of the two fixed forceps blades 1. The two tube seat push-out pieces 6 are arranged with a gradually increasing spacing from top to bottom. The lower ends of the two tube seat push-out pieces 6 are respectively hinged to the forceps tube seat 5. A tube seat tension spring 7 is arranged between the forceps tube seat 5 and the liquid medicine cylinder 3. A forceps holding sleeve 8 is fixedly connected to the lower end of the forceps tube seat 5. Under normal conditions, the tube seat tension spring 7 pulls up the forceps tube seat 5 so that the lower ends of the two tube seat push-out pieces 6 are kept in an outwardly expanded state. Two fixed arms 9 are relatively arranged at the top of the forceps tube seat 5. The inner walls of the two tube seat push-out pieces 6 are respectively and correspondingly rotatably mounted with movable arms 10. The movable arms 10 are rotatably assembled with the corresponding fixed arms 9. The movable assembly of the movable arms 10 can adapt to the angle changes of the two tube seat push-out pieces 6 during use.

[0022] The bottom end of the medicine liquid cylinder 3 is fixedly connected with a forceps holding device, and a medicine liquid channel 11 communicating with the medicine liquid cylinder 3 is provided through the forceps holding device, and a medicine liquid push injection device is provided through one of the fixed forceps pieces 1, and the bottom end of the medicine liquid push injection device movably extends into the medicine liquid cylinder 3, and the forceps holding device is movably arranged through the forceps holding sleeve 8. The medicine liquid cylinder 3 can be pushed out by the medicine liquid push injection device, so that it passes through the medicine liquid channel 11 and enters the eye from the end of the forceps holding device, thereby realizing the addition of medicine into the eye through this embodiment.

[0023] Specifically, the forceps holding device includes a forceps holding rod seat 12 sealed and docked with the forceps tube seat 5, and two forceps holding rod bodies 13 arranged opposite to each other are fixedly connected to the forceps holding rod seat 12. The two forceps holding rod bodies 13 are arranged with a gradually increasing distance from the forceps holding rod seat 12 to the outside, and the ends of the forceps holding rod bodies 13 are respectively provided with forceps holding heads 14, and the liquid medicine channel 11 passes through the forceps holding rod seat 12, one of the forceps holding rod bodies 13 and the corresponding forceps holding head 14. The two tube seat pushing pieces 6 are pinched together toward the fixed forceps pieces 1, and the forceps tube seat 5 and the forceps holding sleeve 8 are pushed out with the cooperation of the fixed arm 9 and the movable arm 10. The forceps holding sleeve 8 is used to squeeze the two forceps holding rod bodies 13, so that the two are brought together and the two forceps holding heads 14 are brought together, so as to facilitate the removal of intraocular separations.

[0024] The liquid medicine push-in device comprises a sealing plug 15 movably mounted in the liquid medicine cylinder 3, a push-in rod 16 is fixedly connected to the top of the sealing plug 15, a long push-in hole 17 arranged opposite to the push-in rod 16 is provided through the fixed forceps 1, a push-in slide block 18 is slidably mounted in the long push-in hole 17, and the push-in slide block 18 is fixedly connected to the push-in rod 16. Pushing the push-in slide block 18 can make the sealing plug 15 move downward synchronously under the action of the push-in rod 16, and the liquid medicine in the liquid medicine cylinder 3 is injected into the eye from the forceps holding head 14 through the liquid medicine channel 11, thereby realizing the replenishment of the intraocular liquid medicine, and the liquid medicine can be replenished at any time during the operation, without separating the present embodiment from the eye, and the operation is simple and convenient. A plurality of injection holes 19 connected to the liquid medicine channel 11 can also be arranged on the forceps holding head 14 to increase the speed of liquid medicine push-in.
