With doing similar popularization in the case where novel intension, therefore the utility model is not limited by the specific embodiments disclosed below.
It is embodied for example shown in Fig. 1 to Fig. 3, a kind of Skin stretching device suitable for the round surface of a wound, including fixed mechanism
And stretching mechanism.
Fixed mechanism, including two fixed rings 63 individual, that caliber size can be adjusted and can be locked, each fixation
With respect to two fixed ears 64 extended horizontally outward are equipped on the side wall of ring 63, it is equipped with adjusting screw rod vertically in the fixed ear 64
61, the adjusting screw rod 61 of the upper and lower two sides of the fixed ear 64 is equipped with the locking nut 62 for locking it with fixed ear 64,
Support rod 65 is equipped between two ipsilateral adjusting screw rods 61 of two fixed rings 63.
Stretching mechanism, including rounded mounting ring 1, the mounting ring 1 between two support rods 65, and its outer wall with
The tangent fixation of two support rod 65, the lower section of the mounting ring 1 is circumferentially spaced-apart to be equipped with multiple groups traction component, and the traction component includes
Rotating part 3 and the tight portion 4 of hook.
Rotating part 3, including fixing shell 31, first gear 33 and second gear 34, the first gear 33 and the second tooth
34 engagement of wheel is located in fixing shell 31, and the first gear 33 is connected with the rotation hand wheel extended to outside fixing shell 31
32, the second gear 34 is connected with the rotary shaft 35 extended to outside fixing shell 31；Rotation hand wheel 32 is rotated, the first tooth is driven
33 rotation of wheel, first gear 33 is engaged with second gear 34, so that second gear 34 be driven to rotate, second gear 34 drives rotation
Axis 35 rotates, and successively changes the angle of looper 42.
Tight portion 4 is hooked, " J " shaped structure is simultaneously located at 3 lower section of rotating part, and the upper end is fixedly connected with rotary shaft 35, the hook
Tight portion 4 has flexible and locking structure.
When in use, operating procedure is as follows for the Skin stretching device:
1. wearing fixed ring 63, Distraction Apparatus is fixed on the limbs of wound using fixed ring 63, adjusting screw rod 61 is adjusted
Appropriate height is saved, keeps the distance between stretching mechanism and the surface of a wound moderate, is then locked adjusting screw rod 61 using locking nut 62
It is fixed；
2. being finely adjusted section to the angle for hooking tight portion 4 according to the shape of the surface of a wound, the angle of looper is adjusted using rotating part 3,
Specifically, rotation rotation hand wheel 32, drives first gear 33 to rotate, first gear 33 drives second gear 34 to rotate, the second tooth
Wheel 34 drives rotary shaft 35 to rotate, and rotates to drive and hook tight portion 4, realizes the angular adjustment to looper 42；
3. the length for hooking tight portion 4 is adjusted according to the shape of the surface of a wound, the skin at surface of a wound edge then tight portion 4 will be hooked caught on
Skin；
4. finely tuning each angle for hooking tight portion 4 again, make each tight portion 4 of hook that there is tension；

Hold together, making skin is suitable for uniting by a seam；
6. removing the Skin stretching device.
According to the size of the surface of a wound, selection uses the quantity of looper 42, and when the surface of a wound is smaller, some loopers 42 would not make
With looper 42 being shunk in tight punch block 41, will not influence the use of other loopers 42 in this way.In the angle for adjusting looper 42
When, looper 42 is possible to penetrate inside skin, when rotation angle is larger when looper 42 is in Primary regulation, can be pre-adjusted fixation
The length of adjusting screw rod 61 in mechanism prevents looper 42 from penetrating relatively deep in meat.
The tight portion 4 of hook includes " J " shaped looper 42 and the punch block 41 with 42 upper socket of looper, the punch block 41
Upper axially spaced-apart is equipped with multiple location holes 43, and 42 top of looper, which is equipped with to be retracted in punch block 41, makes looper 42 in punch block 41
The elastic bumps block 44 that interior movement or protrusion match with location hole 43.This structure uses the structure in flexible umbrella, will be convex
Bittiness 44 enter the location hole 43 of different location, can effectively change the distance between looper 42 and punch block 41, can be simple and effective
It catches on distance farther out or the skin at closer surface of a wound edge, keeps patient more comfortable, not will cause skin drawing strength mistake
Greatly, secondary injury is caused to skin.
In order to which fixed ring 63 is simple and convenient effective when in use, the fixed ring 63 includes arc-shaped moulding plate, described
The both ends of moulding plate opening are equipped with for by the velcro of moulding plate opening lockout.By the bonding position for adjusting two velcro
It sets, adjusts the caliber size of fixed ring 63.
Limb skin is wrapped for a long time, leads to skin injury, therefore is equipped on moulding plate for ventilative air hole.
The above is only the preferred embodiments of the utility model, anyone content according to the present utility model is to the utility model
A little simple modification, deformation and the equivalent replacement made each falls within the protection scope of the utility model.
