The interrupted suture mechanism that is used for corneal graft in this utility model includes the control circuit that is used to control motor, it is characterized in that including:
One base,
Be fixedly installed at least one motor on the base;
Hold needle device, this holds needle device is a partial gear, and this partial gear is hubbed on the base, and connects with the output shaft of motor by travelling gear, and an end that extends base at this partial gear is fixed with the arc suture needle;
Cutting facility, a scissor blade of this cutting facility is fixed on the base by screw, and another scissor blade connects with the output shaft of motor by connecting rod, actuating device;
Wire-clamping device, this wire-clamping device include a wire clamp and the big arm of clamper, and wherein wire clamp connects with the output shaft of motor by the big arm of clamper.
Described interrupted suture mechanism includes two motors, this two motor all is fixed on the base by fixing head, screw, wherein the output shaft of a motor connects with wire clamp by the big arm of clamper, and the output shaft of another motor connects with partial gear, scissors apparatus respectively with actuating device by clutch.
Wired roller is pivoted on the described base.
Described connecting rod passes through to connect with the output shaft of motor behind a cam, the plural gear.
Described partial gear is a sector gear.
The interrupted suture mechanism that is used for corneal graft in this utility model has simulated doctor's cornea sewing process preferably, simplified mechanism, easy operating has imitated the operation action of surgeon's corneal suture formula dexterously with realizing mechanization, has realized the purpose of mechanization operation.Simultaneously owing to adopt hollow suture needle, and significantly reduced the infringement of suture corneal.

The specific embodiment
As shown in Figures 1 to 4, the interrupted suture mechanism that is used for corneal suture operation in this utility model includes a base 1, be located at line roller 27, two motors 2 and 3 on the base 1, hold needle device, cutting facility, wire-clamping device and be used to control two motors and drive the control circuit of holding needle device, wire-clamping device, cutting facility action in regular turn, because this control circuit all can be realized as those of ordinary skill in the art, therefore no longer describes in detail.
As Fig. 1, Fig. 2 and shown in Figure 4, two motors 2 and 3 are fixed on the same side of base 1 by screw 5, motor base 4.
As Fig. 1 and shown in Figure 5, holding needle device is a partial gear 7, it is sector gear, this partial gear 7 is hubbed on the base 1, and be positioned at motor 2, the same side of 3, this partial gear 7 connects with the output shaft of motor 2 by a travelling gear 6, this partial gear 7 is set with an arc suture needle 9 at the end that it extends base 1 by holder 8 simultaneously, this arc suture needle 9 is one to have most advanced and sophisticated hollow pipe, make suture can pass this arc suture needle 9, this arc suture needle 9 does not have a most advanced and sophisticated end fixedly to be located on the partial gear 7, rotates with the rotation of partial gear 7.
As shown in Figure 3 and Figure 4, cutting facility 11 includes two scissor blades 10,12, wherein a scissor blade 10 is fixed on the base 1 by screw 23, holder 24, and be positioned at the opposite side of motor 2,3, another scissor blade 12 by connecting rod 21, cam 19, gear 20 and 25 and 26 and the clutch (not shown) connect with the output shaft of motor 2.
As shown in Figures 2 and 3, wire-clamping device includes a wire clamp 13 and the big arm 14 of a clamper, wherein a jig arm of wire clamp 13 is fixed on the end of the big arm of clamper and 14 by screw 15, another jig arm connects by the output shaft of backguy (not shown) with motor 3, and between two jig arm, connect by the spring (not shown), the big arm 14 of clamper also is connected with the output shaft of motor 3 simultaneously, drives the swing that the big arm 14 of this clamper is made certain angle by motor 3.
Be used in this utility model corneal graft between the operating process of breaking joint mechanism as follows:
At first utilize Connection Block 17, screw 18 that base 1 is fixed on robot or other plant equipment, drive whole interrupted suture mechanism to the position that needs corneal transplantation to sew up by this robot; Then by motor 2 driven wheels 6 and further driving partial gear 7 rotations, drive arc suture needle 9 and pass cornea, driving wire-clamping device by motor 3 again will clamp with the suture that arc suture needle 9 passes, and suture is pulled out with the swing of the big arm 14 of clamper, drive partial gear 7 revolutions by motor 2 simultaneously, extract arc suture needle 9, i.e. arc suture needle 9 is return along the suture of clamping; Drive scissors apparatus by motor 2 at last and cut off suture, and the manual knotting of suture is got final product.Then, arrive the position that second pin is sewed up, repeat said process, can finish the stitching of whole cornea again by robot rotating base one angle.
