In conjunction with each width figure, the present invention is described in detail more below:
Fig. 1 is the overall construction drawing of the medical suturing instrument that proposes of the present invention.What Fig. 2 showed is enclosure structure chart.The present invention is by comprising that shell 1, urceolus 2, left handle 3-1, right handles 3-2, left needle forceps 4-1, right needle forceps 4-2, elasticity push-plate 5, a left side hold that pin connection rod set 6-1, the right side hold pin connection rod set 6-2, left folding connection rod set 7-1, right folding connection rod set 7-2, left push-plate connection rod set, right push-plate connection rod set forms.Handle, around doing oscillating motion with the fixing rotating shaft of shell, resets by the interaction force between handle back-moving spring I301, handle back-moving spring II302.
Figure 3 shows that straight line stitching instrument pin 401 and stitching thread 402 that the present invention uses.There is annular groove at sewing needle 401 two ends, so that at left needle forceps 4-1,4-2 and hold under pin connection rod set 6-1,6-2 combined effect and more firmly block.Be different from the connected mode of traditional stitching thread at sewing needle, the medium position of stitching thread 402 of the present invention in straight line stitching instrument pin 401.Sewing needle is same with stitching thread is contained in the present invention.
Figure 4 shows that the structure chart of elasticity push-plate 5.Push-plate baffle plate 501 forms a whole by being rigidly connected between push-plate lower jaw 506, and push-plate ratchet 502 contacts with push-plate connecting rod II802, as the power source of push-plate motion, push-plate is rotated along clockwise direction.Self-locking ratchet 504 is subject to 104 effects of stop push jack to ensure push-plate reverse self-locking.Push-plate lower jaw 506 is connected by snap close lasso 508 with push-plate maxillary 509, and snap close lasso 508 can prevent the axially-movable between palate and lower jaw, but allows relatively rotating of certain angle, and it relatively rotates angle and controls by push-plate spring 507.Push-plate maxillary 509 tops are the concavo-convex shape of dividing equally, when work, make two of left and right hold pin connecting rod gag lever post 603 respectively alternately in jog, impel two to hold pin connection rod set 6-1,6-2 and pump, be alternately clamped in left and right two needle forceps 4-1,4-2 thereby realize sewing needle 401.
Figure 5 shows that the structure chart of holding pin connection rod set 6-1,6-2.Hold pin pitman shaft 304 by a side handle with hold pin connecting rod 601 and link together, hold on pin connecting rod 601 and have straight trough mouth, allow connecting axle 304 to have in notch mobile in a small amount.Hold pin connecting rod 601 and form with holding pin push rod 602 relation that is rotatably assorted, hold pin push rod and by transmission lever I604 and transmission lever II605, power is passed to and held pin dop 606.Holding pin dop 606 front ends has semi-circular groove, for blocking sewing needle 401.
Shown in Fig. 6, push-plate connecting rod II802 and push-plate connecting rod I801 are connected through the hinge, and push-plate connecting rod I801 is driven by corresponding side handle 3-1,3-2, does rectilinear motion along the chute in shell 1, and push-plate connecting rod II802 promotes push-plate ratchet 802 in the interior rotation of shell 1.When elasticity push-plate 5 moves, folding connecting rod I702 traction folding connecting rod II703 moves along a straight line.Between handle 3, folding connecting rod I702, folding connecting rod II703, form slider-crank mechanism.Folding connecting rod II703 drives left and right needle forceps 4-1,4-2 to realize open and close movement, crank drives left and right pin connection rod set 6-1, the 6-2 motion of holding simultaneously, in the time that left and right needle forceps 4-1,4-2 are completely closed, keep the pin dop 606 of holding of clamp position to unclamp, the pin dop 606 of holding of opposite side arrives clip position.In the time again opening left and right needle forceps, sewing needle 401 forwards opposite side to from a side of needle forceps, passes thereby drive the tissue of stitching thread 402 between stitching clamp, completes sew application.
Figure 7 shows that housing parts of the present invention.Wherein, the elastic force driving that holding pin rod spring 102 provides is held pin connection rod set and is moved downward, and stop push jack 104 prevents that elasticity push-plate from rotating counterclockwise, push-plate push rod shell fragment 106 reset drives as push-plate push rod II802.
The importation of the medical suturing instrument that the present invention is a kind of has an automatic needle exchange function using handle 3 as power, by drive link assembly resultant motion, realize sewing needle of every folding automatically on needle forceps evolution once, sew up and the complicated surgical procedures such as knotting thereby complete.Figure 8 shows that the duty of the present invention when sewing up, Figure 9 shows that the duty of the present invention when tiing a knot.
The work process of this stiching instrument is: when initial, sewing needle 401 is placed in arbitrarily among needle forceps 4-1 or 4-2, to be placed in 4-1 as example, and is held pin connection rod set 7-1 and blocks, and handle is in open configuration.When work, doctor operates two handle closures, and handle drives is held pin connection rod set 6-1,6-2, and folding connection rod set 7-1,7-2 and push-plate connection rod set are moved simultaneously.Folding connection rod set drives needle forceps 4-1,4-2 closure; Hold pin connection rod set 6-1 and become releasing orientation from stuck state, connection rod set 6-2 becomes stuck state from releasing orientation, and state alternately, can get loose sewing needle 401 and taken away by right side needle forceps 4-2, as shown in Figure 9 from the needle forceps 4-1 of left side; Push-plate connection rod set promotes elasticity push-plate 5 and turns an angle, and push-plate maxillary 509 concavo-convex positions, top exchange thereupon; The state that pin connecting rod gag lever post 603 is held in order changes, and its objective is the state maintaining after abbot's pin connection rod set 6-1 and 6-2 replace.After handle unclamps, sewing needle 401 is from originally becoming in needle forceps 4-2 in needle forceps 4-1, thereby completes the function of threading a needle.This apparatus one is opened one and is closed and be a work process, and each folding all completes the action of once threading a needle, thereby realizes final stitching function, and if broken away from former operation process and will realize and sew up certain use circle curved suture needle the restriction circling.
Below schematically the present invention and embodiment thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of embodiments of the present invention, and actual structure is not limited to this.So; if those skilled in the art is enlightened by it; in the situation that not departing from the invention aim; adopt transmission, driving device and the connected mode of other form without the creationary design frame mode similar to this technical scheme and embodiment, all should belong to protection scope of the present invention.
