sleeve

5, 6 left ends of screw rod run through spring leaf 2 and with push cylinder 4 rotate and be connected, 2 front and back both sides wall left end downside are equipped with a plurality of arc pieces 7 along left and right directions evenly distributed respectively around the spring leaf, 7 openings of arc pieces of front and back both sides are carried on the back mutually, 1 lower extreme of supporting seat is equipped with fixed band 8, the connection can be dismantled to two free ends of fixed band 8.

Can dismantle the connection in order to realize two free ends of fixed band 8, fixed band 8 front end be equipped with the rectangle box 9 that link up around, the rotation of rectangle box 9 upper end is connected with turns over board 10, turns over the board 10 front end left and right sides and is equipped with the spacing post 11 that is located rectangle box 9 respectively, the fixed band 8 rear end left and right sides is equipped with a plurality ofly respectively along fore-and-aft direction evenly distributed and can with spacing hole 12 of spacing post 11 complex.

In order to rotate the screw rod 6 conveniently, a hand wheel 13 is arranged at the right end of the screw rod 6.

In order to take the device conveniently, the front side and the rear side of the sleeve 5 are respectively provided with a finger ring 14.

In order to prevent the blood from flowing to other parts of the wound, the lower end of the fixing band 8 is provided with a cotton pad 15.

In order to prevent the push rod 3 from swinging too much, the length of the screw rod 6 is equal to that of the push rod 3.

When the utility model is used, the right end surface of the push cylinder 4 is contacted with the spring piece 2 in the initial state, and the two free ends of the fixing belt 8 are separated;

firstly, a wound is cut on the operation part of the body of a patient by using a scalpel, the number of the arc pieces 7 for retracting the wound is selected according to the length of the wound, fingers are inserted into the finger ring 14 to take the device, and the arc pieces 7 at two sides are placed in the wound, so that the arc pieces 7 are large in force application area and cannot easily cause secondary damage to the wound like a hook;

the hand wheel 13 is rotated clockwise, the hand wheel 13 drives the screw rod 6 to rotate clockwise, the screw rod 6 moves leftwards while rotating due to the threaded connection of the screw rod 6 and the sleeve 5, the screw rod 6 drives the push cylinder 4 to move leftwards, the push cylinder 4 drives the two push rods 3 to swing outwards, the push rods 3 drive the front side wall and the rear side wall of the spring piece 2 to move outwards, the front side wall and the rear side wall of the spring piece 2 drive the arc-shaped piece 7 to retract a wound, the spring piece 2 is kept at the current position due to the self-locking property of the threaded connection of the screw rod 6 and the sleeve 5, the wound retraction state does not need to be kept by manpower all the time, the workload of medical staff is reduced, the speed is uniform, the wound stress is uniformly distributed in the wound retraction process, and the secondary injury caused by overexertion is avoided;

when the wound is completely retracted and the part needing operation is completely displayed, the fixing band 8 is attached to the body of a patient, the turning plate 10 is rotated upwards, the turning plate 10 drives the limiting column 11 to rotate upwards, the left end of the fixing band 8 is inserted into the rectangular box 9, when the fixing band is adjusted to a proper length, the turning plate 10 is pressed downwards, the turning plate 10 drives the limiting column 11 to rotate downwards, the limiting column 11 is clamped in the limiting hole 12 at the moment, the free end of the fixing band 8 cannot move, the fixing of the device is realized, the phenomenon that the inclination of the retractor is easily caused by the lack of fixing after the wound of the patient is retracted is avoided, so that danger occurs, the cotton pad 15 is positioned below the wound at the moment, and the blood of the patient is prevented from flowing to other parts of the body;

fixing of the device is completed at the moment, the wound is kept in a retracting state, a doctor performs an operation, after the operation is completed, the hand wheel 13 is rotated anticlockwise, the hand wheel 13 drives the screw rod 6 to rotate anticlockwise, the screw rod 6 is in threaded connection with the sleeve 5 and moves rightwards while rotating, the screw rod 6 drives the push barrel 4 to move rightwards, the push barrel 4 drives the two push rods 3 to swing inwards, the push rods 3 drive the front side wall and the rear side wall of the spring piece 2 to move inwards, the front side wall and the rear side wall of the spring piece 2 drive the arc-shaped piece 7 to return to an initial state, the arc-shaped piece 7 is taken out of the wound, the turning plate 10 is rotated upwards, the turning plate 10 drives the limiting column 11 to rotate upwards, the left end of the fixing band 8 is taken out of the rectangular box 9, the turning plate 10 is pressed downwards, the turning plate 10 drives the limiting column 11 to rotate downwards, the device is taken out, the wound is sewn, and the device is sterilized and used.
