Left and right handle 3-1,3-2 are rotatedly connected with shell by described rotatable handle axle 103 respectively, are separately installed with the handle back-moving spring in described left and right handle 3 inboards.
The below is described in detail the present invention in conjunction with each width of cloth figure again:
Fig. 1 is the overall construction drawing of the medical suturing instrument that proposes of the present invention.What Fig. 2 showed is the 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 resets by the interaction force between handle back-moving spring I301, the handle back-moving spring II302 around doing oscillating motion with the fixing rotating shaft of shell.
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 and right needle forceps 4-1,4-2 and hold under pin connection rod set 6-1, the 6-2 combined effect and more firmly block.Be different from traditional stitching thread in the connected mode of sewing needle, stitching thread 402 of the present invention is in the medium position of straight line stitching instrument pin 401.Sewing needle and stitching thread are contained in the present invention equally.
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 the push-plate lower jaw 506, and push-plate ratchet 502 contacts with push-plate connecting rod II802, and the power source that moves as push-plate rotates push-plate along clockwise direction.Self-locking ratchet 504 is subjected to 104 effects of stop push jack to guarantee the 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 the lower jaw, but allows relatively rotating of certain angle, and it relatively rotates angle by 507 controls of push-plate spring.Push-plate maxillary 509 tops are the concavo-convex shape of dividing equally, hold pin connecting rod gag lever post 603 and alternately be in respectively jog for two about making during work, impel two to hold pin connection rod set 6-1,6-2 and pump, thus realize sewing needle 401 alternately be clamped in about among two needle forceps 4-1, the 4-2.
Figure 5 shows that the structure chart of holding pin connection rod set 6-1,6-2.Hold pin pitman shaft 304 with a side handle with hold pin connecting rod 601 and link together, hold and have the straight trough mouth on the pin connecting rod 601, allow connecting axle 304 in notch, to have mobile in a small amount.Hold pin connecting rod 601 and form being rotatably assorted relations with holding pin push rod 602, hold the pin push rod and power is passed to held pin dop 606 by transmitting bar I604 and transmission bar II605.Holding pin dop 606 front ends has semi-circular groove, is used for blocking sewing needle 401.
Shown in Figure 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 respective side handle 3-1,3-2, do rectilinear motion along the chute in the shell 1, and push-plate connecting rod II802 promotes push-plate ratchet 802 in shell 1 interior rotation.In the time of 5 motion of elasticity push-plate, folding connecting rod I702 traction folding connecting rod II703 moves along a straight line.Form slider-crank mechanism between handle 3, folding connecting rod I702, the folding connecting rod II703.Folding connecting rod II703 drives left and right needle forceps 4-1,4-2 and realizes open and close movement, crank drives left and right pin connection rod set 6-1, the 6-2 motion of holding simultaneously, when left and right needle forceps 4-1,4-2 are fully 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.When 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, finishes 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 the pin connection rod set and is moved downward, and stop push jack 104 prevents that the elasticity push-plate from rotating counterclockwise, push-plate push rod shell fragment 106 reset drives as push-plate push rod II802.
The present invention is a kind of to have from moving the medical suturing instrument of pin function with the importation of 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 finish.Figure 8 shows that the duty when the present invention is used to sew up, Figure 9 shows that the duty when the present invention is used to tie a knot.
The work process of this stiching instrument is: when initial, sewing needle 401 places arbitrarily among needle forceps 4-1 or the 4-2, placing 4-1 as example, and is held pin connection rod set 7-1 and blocks, and handle is in open configuration.During work, it is closed that the doctor operates two handles, 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.It is closed that the folding connection rod set drives needle forceps 4-1,4-2; Hold pin connection rod set 6-1 and become releasing orientation by stuck state, connection rod set 6-2 becomes stuck state by releasing orientation, namely state alternately so that sewing needle 401 can get loose from the needle forceps 4-1 of left side and be taken away by right side needle forceps 4-2, as shown in Figure 9; The push-plate connection rod set promotes elasticity push-plate 5 and turns an angle, and concavo-convex position, push-plate maxillary 509 tops exchanges thereupon; The state that pin connecting rod gag lever post 603 is held in order changes, and its objective is the state of keeping after abbot's pin connection rod set 6-1 replaces with 6-2.After handle unclamped, sewing needle 401 was among the needle forceps 4-2 by originally being in to become among the needle forceps 4-1, thereby finished the function of threading a needle.This apparatus one is opened one and is closed and be a work process, and the action of once threading a needle is all finished in each folding, thereby realizes final stitching function, and if broken away from and will realize sewing up certain use circle curved suture needle in the former operation process, and do the restriction of circular motion.
Below schematically the present invention and embodiment thereof are described, this description does not have restricted, and shown in the accompanying drawing also is 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 do not break away from the invention aim; adopt transmission, driving device and the connected mode of other form without creationary design frame mode and the embodiment similar to this technical scheme, all should belong to protection scope of the present invention.
