Each miniature needle holder has a needle holding arc tube and a miniature motor.
Description
Technical field
The present invention relates to a kind of automatic sewing mechanism that is used for the corneal suture technology.
Background technology
The needle holder that uses in the eye cornea surgical operation is pliers at present, promptly use pliers clamping arc-shaped slit to realize transplanting and suturing skill at cornea, but in operation process because the arc suture needle used is the micron order suture needle, so make the front end of pliers very thin, location and clamping weak effect to the arc suture needle, make the doctor when performing an operation, be difficult to suture needle is controlled, had a strong impact on the precision of operation and the rehabilitation of postoperative.
For this reason, the creator among the present invention relies on it to be engaged in the experience and the practice of relevant industries for many years, and through concentrating on studies and developing, creates a kind of automatic sewing mechanism that can carry out mechanized operation to the arc suture needle finally.
Summary of the invention
Main purpose of the present invention is to provide a kind of automatic sewing mechanism, utilizes this automatic sewing mechanism can make the doctor not re-use pliers and undergos surgery, and realizes the purpose of mechanized operation.
The automatic sewing mechanism that is used for corneal suture operation among the present invention includes a propeller, the little needle holder of two arcs and is used to control the motor of the little needle holder of two arcs, it is characterized in that:
Described propeller include one with by the hinged connecting rod of the mechanism rack of robot control and can make the trace of telescopic moving with described connecting rod, described trace is provided with a pivot that is used to be pivoted the little needle holder of two arcs at its other end;
The little needle holder gyroaxis of described two arcs and is connected with the output shaft of two motors on same axis.
The end of described connecting rod is set with the sleeve of a hollow, and is provided with nut in this telescopic end or inside, and described trace is provided with screw thread at the end that it cooperates with connecting rod.
The little needle holder of described arc includes a fluting arc that is used for the medical suture needle of clamping arc and holds a syringe and a micromachine, and the described syringe of holding has extended in parallel two wing plates along the both sides of slotting; The output shaft of described micromachine and one passes described arc and holds syringe two wing plates and can drive this arc and hold syringe and do to clamp and to fixedly connected with the screw mandrel that unclamps action, and the output shaft of a described motor is fixedlyed connected with the wing plate that described arc is held syringe.
Automatic sewing mechanism among the present invention can allow entire mechanism advance to the operating position or return back to by means of propeller and change the pin position, and do simultaneously in opposite directions or reverse motions by two little needle holders of arc of two motor-driven, realize acupuncture treatment, pull out pin and change the pin process, imitate the operation action of surgeon's corneal suture formula dexterously, realized the purpose of mechanization operation.

The specific embodiment
As shown in Figure 1, the automatic sewing mechanism that is used for the corneal suture technology among the present invention includes a propeller 1, the little needle holder 2 of two arcs and is used for controlling respectively the motor 3,4 of the little needle holder of two arcs.Wherein:
As shown in Figure 5, the little needle holder 2 of arc includes the sleeve 24 and alignment pin 25 that an arc is held syringe 20, micromachine 21, screw mandrel 22, decelerator 23 and is used to connect screw mandrel 22 and micromachine output shaft.The arc that arc is held syringe 20 is identical with the arc of medical suture needle 6, and inner diameter is convenient to the fixing of medical suture needle 6 and is extracted greater than the external diameter of the medical suture needle 6 of arc.This arc is held syringe 20 and is offered an arcuate groove 26 along the inboard of arcuate directions, has extended in parallel two wing plates 27 and 28 along the both sides of this arcuate groove 26.On same axis, be provided with two perforation (not shown)s in this two wing plate 27,28, and be provided with nut 29 by welding in the outside of two perforation outer peripheral edges, wing plate 27,28.Micromachine 21 is fixedlyed connected with screw mandrel 22 with alignment pin 25 by sleeve 24 with the output shaft after decelerator 23 is connected, and by 22 rotations of micromachine 21 drive screw mandrels, the hand of spiral at screw mandrel 22 both ends is opposite, when the nut 29 on two wing plates 27,28 with after screw mandrel 22 is connected, under the drive of screw mandrel 22, can do in opposite directions or adverse movement, hold syringe 5 do clampings or unclamp action thereby drive arc, produce good clamping and locating effect.On wing plate 28, offer a perforation (not shown) separately, utilize this perforation to fixedly connected with the output shaft of motor 3 or 4 behind decelerator in the automatic sewing mechanism, when motor 3 or 4 runnings, can drive that arc is held syringe 20, micromachine 21 is finished arcual stitching campaign together, thereby realize that arc holds syringe 20 and drive the action that cornea is passed in the medical suture needle 6 of arcs.
The operating process of automatic sewing mechanism that is used for the corneal suture technology among the present invention is as follows:
1. utilize support whole automatic sewing mechanism to be moved to the top, position of required stitching;
2. utilize angle of rake advancing to have the arc suture needle to one and another has the little needle holder of two arcs of arc suture needle to deliver to specified suture location;
3. first little needle holder band suture needle, second little needle holder is temporarily idle, drive two little needle holders separately by two motors and make move toward one another, wherein first little needle holder band suture needle and is carried out the acupuncture treatment process, makes suture needle 6 front end of suture needle when cornea passes enter second little needle holder;
4. clamp suture needle 6 by second little needle holder, at this moment, the motor counter-rotating drives two little needle holders and makes reverse motions, pulls out the pin process;
5. when cornea is left in suture needle, the motor stall, propeller return back to certain altitude;
6. motor just changes, and two little needle holders are made move toward one another, by second little needle holder pin is sent to first little needle holder;
7. first little needle holder is clamped suture needle, and the motor stall drives entire bracket by robot and turns over certain angle, enters the sewing process of next pin, and repeats above-mentioned steps.
