Detailed Description

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Example 1:

as shown in figures 1-4, the device for incision closure and indwelling tube fixation comprises an adhesive sheet, wherein the adhesive sheet comprises a first adhesive sheet 1 and a second adhesive sheet 2, a plurality of locking holes 3 with internal threads are formed in the first adhesive sheet 1, a plurality of adjusting rods 4 with threads are formed in the second adhesive sheet 2, the adjusting rods 4 can be pulled or rotated so as to adjust the distance between the first adhesive sheet 1 and the second adhesive sheet 2, the adjusting rods 4 are clamped and fixed in the corresponding locking holes 3, and the first adhesive sheet 1 and the second adhesive sheet 2 are folded and kept closed by extruding an incision 16 through the adjusting rods 4. The adjustment stem 4 is perpendicular to the closed edge of the adhesive wafer and the perpendicular fixation of the adjustment stem 4 improves the polymerization of the incision 16. The adjacent lock holes 3 are connected through a strip-shaped connecting piece 12, the distance between each two adjacent lock holes 3 and the distance between each two adjacent adjusting rods 4 are 1-3cm, and the connecting piece 12 ensures that the closing force of the patch is continuously and uniformly transmitted. One end of each adjusting rod 4 is fixed on the second adhesive patch 2 through an anchor 10, and the free end of each adjusting rod 4 is provided with a handle 11.

Establish direction ladder 5 on the adhesion piece two 2, positioning seat 6 and articulate in seat lid 7 of positioning seat 6, a logical groove 8 is seted up to positioning seat 6 top surface level, lead to logical groove 8 on 5 upper ends intercommunication positioning seat 6 of direction ladder, lower extreme intercommunication locating hole 9, locating hole 9 is close to the closed limit of bonding sheet, the bending and the fracture of keeping somewhere the pipeline can effectively be avoided in the slope design of direction ladder 5, seat lid 7 will keep somewhere the pipe restriction in the logical groove 8 of positioning seat 6, prevent to keep somewhere the pipe and deviate from positioning seat 6, avoid keeping somewhere the pipe aversion, positioning seat 6 can let patient also free activity when wearing the pipe, keep somewhere more comfortablely.

The operation process is as follows:

before the thoracoscope operation is finished, a patient is still in a cannula anesthesia state, after a thoracic surgeon finishes the paravertebral nerve block catheterization operation under the auxiliary direct vision of a thoracoscope, the first adhesive sheet 1 is firstly attached to one side of the incision 16, the second adhesive sheet 2 is attached to the other side of the incision 16, the first adhesive sheet 1 and the second adhesive sheet 2 are lightly pressed by hands to be firmly adhered to the skin, the lock hole 3 is lightly pressed by one hand of the surgeon, the handle 11 at the free end of the adjusting rod 4 is pulled by the other hand to penetrate through the lock hole 3, and the distance between the first adhesive sheet 1 and the second adhesive sheet 2 is pulled by the adjusting rod 4, so that the incision 16 is driven to be closed, and the purpose of suturing the incision 16 is achieved. The folding in the mode enables the skin edges of the incision tissues to turn outwards and enables the tissues to be wrinkled, the formation of scars is effectively reduced, if the incision tissues are folded too tightly, the adjusting rod 4 in the keyhole 3 is loosened, the tightening degree of the incision tissues can be adjusted at will, and therefore the accurate closing of the incision 16 is achieved. When the adjusting rod 4 is adjusted to the optimal recovery position of the closed cut 16, the doctor manually rotates the adjusting rod 4 to enable the thread of the adjusting rod 4 to tilt and rotate, and the thread is fastened and fixed on the inner thread of the lock hole 3 in a threaded connection mode. Then, the excess part of the free end of the adjusting rod 4 is cut off by scissors, and the closing operation of the incision 16 of the paravertebral nerve block is completed.
