Description
Technical field
The present invention relates to medical apparatus and instruments, are that a kind of surgical wound exempts to stitch device.
Background technology
At present, suture and skin nailing machine are the major appliances used in surgical wound closing course, although after improvement,
But still there is deficiency, mainly stitching holes produce new wound, increase infection chance;Scolopendra shape cicatrix is left after healing;Close
Wound protection dynamics after conjunction is not enough, when especially patient body is stirred, wound is produced and is torn, and pain substantially, is also unfavorable for
Wound healing;Simultaneously suturing skill is also an important basic training of surgeon, time-consuming, laborious, take a lot of work.For this purpose, this area
Technical staff provides and exempts to stitch fluid sealant, skin Closure Srips and exempt to stitch slide fastener, exempt to stitch the products such as pulling buckle, for realizing Wound suturing-free mesh
's.However, exempt from seam fluid sealant, skin Closure Srips wound is fully sealed, the wound without transudate is only applicable to;Exempt to stitch slide fastener, seam
Close pulling buckle, it is impossible to protect wound to avoid the impact of tension force and shearing force well.Meanwhile, these products are due to more difficult standard during operation
Really engage wound, when slightly moving, in without the fixed protection of strength, easily wound pulled apart, the speed that cicatrizes a wound becomes wound
Slowly, it is easily caused sometimes repeated infection.These products cause clinical application range extremely narrow due to there is above-mentioned deficiency, and current wound is still
Continue to use based on suture technology.
The content of the invention
It is an object of the present invention to provide a kind of surgical wound exempts to stitch device, it can solve the problem that the deficiencies in the prior art.
The present invention for achieving the above object, is achieved through the following technical solutions:A kind of surgical wound exempts to stitch device, including the

5th movable plate 13 and the 6th movable plate 14 install spongy layer 45 with adhesive tape junction, or in the bottom side end face of each movable plate
Blood and slime or transudate spout are opened up, as shown in Figure 3.This structure is easy to wound healing, and patient's pain can be reduced in nursing
Pain, and reduce infection.
The Wound suturing-free device of the present invention provides four embodiments, but the solution of the present invention is not limited in scope of embodiments
It is interior.
As Figure 1-Figure 4, what it was mainly used in linear type wound exempts from seam to the two of one of embodiment of the present invention and embodiment
Healing, two embodiment differences are mainly the difference of clamp device.The clamp device of embodiment 1 is nut-screw, such as Fig. 1 institutes
Show:Two nuts are separately mounted on the first movable plate 4 and the second movable plate 3, screw rod and nut screw connection.Install on movable plate
Nut is how many, and depending on the length of movable plate, the nut-screw shown in Fig. 1 is two groups, and the Wound suturing-free device of the present invention can root
Need to make multiple models according to difference, one group of nut-screw can be installed on movable plate, 3 groups or more multigroup nut can be also installed
Screw rod.Clamp device shown in Fig. 2 is the structure of fastening strip tooth and groove fit, and its structure is:It is fixedly mounted with and is equipped with a bayonet strip
8, fastening strip 8 is arranged on the first movable plate 4, and several latches 10 are arranged on fastening strip 8, and the upper surface of the second movable plate 3 is arranged
Several grooves 9, latch 10 are coordinated with groove 9, and this structure is more applicable for the distance and tautness of two movable plates of adjustment, effect
Fruit is more preferably.The structure of embodiment three is mainly used in the seam of exempting from of minimally invasive wound and heals, and the change of its structure is turned to:First movable plate
4 and second movable plate 3 be arc shape board, two arc shape board inside edges are mutually rounded after touch, two arcuation movable plates it is interior along radian
Semicircular, when the inside edge termination of two arcuation movable plates touches, the intermediate cavity of two arcuation movable plates is rounded.This
Bright this structure is mainly used in the Wound suturing-free healing of minimally invasive boring operation operation, and the clamp device of this structure can be adopted
Nut-screw, may also be employed the structure of fastening strip tooth and groove fit.Certainly, the present invention makes the first movable plate 4 and the second movement
Plate 3 also has more implementation to the structure that neighbor distance reduces direction movement, but the structure that the application is provided only is manufactured into
This preferred version that is low, being easy to operation, tautness good.
The structure of the four of the embodiment of the present invention, is mainly used in wound multi-direction, a plurality of bifurcated wound in the same plane
Exempt from seam healing, its change structure in base structure is:First movable plate, 4 one end is moved by the first connector 38 and the 3rd
21 one end of dynamic plate connects, and the 3rd movable plate 21 is connected with the 4th movable plate 20 by clamp device, and 20 one end of the 4th movable plate leads to
Cross the second connector 44 to be connected with rebound 25, one end of the second movable plate 3 passes through the 3rd connector 29 and the 5th movable plate 14
Connection, the 5th movable plate 14 are connected with the 6th movable plate 13 by clamp device, and 13 one end of the 6th movable plate is by the 4th connection
Part 35 is connected with rebound 25.
When Wound suturing-free device of the present invention is used, the adhesive tape on two movable plates is sticked to into wound both sides, so
Adjusting clamp device afterwards makes the movable plate of wound both sides move to wound, so as to drive wound to make up, forms crowded in wound circumference
Pressure, plays the effect of wound suture, finally fixes clamp device.Can also be after surgery for different wounds
One day, second day or the bleeding according to postoperative wound and transudate situation adjustment clamp device.The Wound suturing-free device of the present invention
Can also protect wound not by tension force, influence of shear force, define a protection domain for avoiding external disturbance, cicatrize a wound
Speed faster.Wound suturing-free device Clinical practice of the present invention 21, wherein 3 is bifurcated wound, other are linear type wound
Mouthful, to exempt to stitch device and operate with simplicity, the pain of the wound of patient substantially mitigates, and second day patient of Post operation can leave the bed work
It is dynamic, there is not wound displacement, inconsistent phenomenon, it is easy to nurse, speed of wound healing is than suture operation 1-3 days in advance, wound healing
Afterwards without deformation and deeper cicatrix.The present invention can form extruding force to wound, make up wound, play the effect of wound suture,
Wound can also be protected not to be affected by tension force, shearing force, one be formed not by the protection domain of external interference.The characteristics of of the invention
It is simple structure, the various wounds of adaptation, clinical manipulation is convenient, mitigate patient pain, cicatrix is few, healing is fast.
