Specifically, after the operation is finished, because the separating forceps are made of stainless steel or titanium alloy, the pressing arm 4 moves outwards under the action of elastic force, the sleeve 3 is driven to move backwards through the linkage rod 401, and the sleeve 3 moves backwards without acting force on the jaw connecting rod 502, so that the hook-shaped forceps 503 move outwards to finish the opening action.
The invention also discloses a use method of the surgical angle separation forceps for glaucoma, which comprises the following steps:
s1: when the forceps are used, the forceps handle 1 is held by hand and used as fingers for pressing the arms 4, the pressing arms 4 move inwards, the sleeve 3 is driven to move forwards through the linkage rod 401, the connecting rod 501 is fixedly connected with the forceps handle 1, the tightening ports at the end parts of the sleeve 3 move forwards to enable the jaw connecting rods 502 of the two forceps parts 5 to move inwards to finish closing actions, the two hook forceps 503 are closed, the iris is clamped and pulled, and when the two hook forceps 503 are attached to clamp the iris, the pressing arms 4 at the two sides are propped against the limiting stop lever 11 to limit the pressing arms 4 to continuously approach the forceps handle 1;
s2: when the iris is pulled, one finger holding the forceps pushes the pulling plate 121, so that the pulling plate 121 drives the positioning rod 12 to move out of the positioning holes 112 of the two limiting stop rods 11, the limiting stop rods 11 do not limit the pressing arms 4 any more, a doctor continues to apply force to the pressing arms 4, under the condition that the sleeve 3 cannot continue to move, the linkage rod 401 drives the sliding block 141 to slide in the sliding groove 14, and the pressing arms 4 continue to approach the forceps handle 1;
s3: when the pressing arm 4 moves to the body of the forceps handle 1, the pressing arm 4 applies force to the force-bearing plate 902, the force-bearing plate 902 drives the piston plate 9 to move in the working shell 7 through the push rod 901, so that the piston plate 9 discharges perfusate in the working shell 7 into the working groove 8 through the first one-way valve, flows into the flow groove 6 communicated with the working groove 8 and finally is discharged through the through hole 5031 on the hook-shaped forceps 503, and the perfusate discharged from the through hole 5031 can wash and separate membranous tissues to assist the forceps part 5 to separate membranous tissues;
s4: after the operation is finished, as the separating forceps are made of stainless steel or titanium alloy, the pressing arm 4 moves outwards under the action of self elastic force, the sleeve 3 is driven to move backwards through the linkage rod 401, the sleeve 3 moves backwards without acting force on the jaw connecting rod 502, the hook forceps 503 moves outwards to finish the opening action, the push rod 901 is reset and moved under the pulling of the elastic force of the first elastic element 903, and when the push rod 901 drives the piston plate 9 to move backwards, perfusate in the liquid storage tank 10 is extracted through the second one-way valve for later operation of the separating forceps.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
