Abstract

The utility model discloses a sleeve type skin extensor, belonging to medical instrument for plastic surgery, which comprises a sleeve, an inner core and a hood; the cylindrical inner core is arranged in the sleeve; a turncap at one end of the inner core is fitted with a flange at the end of the sleeve; the fitting mode for the turncap and the flange is that the flange is a ratchet wheel with teeth on the circumferential surface, while a pawl on the turncap is clipped in a tooth space of the ratchet wheel; a pin seat with a support pin protruded out of the bottom of the sleeve is arranged at the other end of the inner core; at the cylindrical part where the inner core is overlapped with the sleeve, a plurality of through holes for threading with the spacing of 5 to 10 mm are arranged on the inner core and the sleeve; the hood with axial opening gap is sleeved outside the sleeve. The skin extensor has the advantages of eliminating the pain during skin transplantation and reconstruction of wound surface using skin flap, reducing the risk of infection, shortening the rehabilitation period, alleviating the economic burden of the patients, eliminating or reducing the scar after recovery, and leaving the beautiful appearance for the patient.

Description

Sleeve type skin extending device

1, technical field: this utility model belongs to medical apparatus and instruments, the skin extending apparatus that especially a kind of plastic surgery uses.

2, background technology: the skin injury that wound causes is common at surgical clinical, if damaged area is bigger, can not draw stitching over to one's side by first phase, then need implement auto-skin grafting or from body Vessel Skin Flap wound surface.The shortcoming of skin-grafting and Vessel Skin Flap is will cause a new wound surface for the district, increasing the patient suffering, secondly is that skin and the skin donor site pigment of transplanting deepened, and forms tangible aberration with peripheral normal skin, influence attractive in appearancely, give patient's body and stay next lifelong " marking " psychologically.Particularly the skin transplanted of the damaged person of scalp can not long hair, and external plastic surgery designs a kind of silicon capsule and is embedded near the scalp wound surface, and water filling in capsule regularly manually causes a tumor, utilizes the scalp flap coverage of expansion.But this method complication is more, and also inapplicable to the skin injury at other positions of human body.

3, summary of the invention: the purpose of this utility model is a kind of light easy-operating skin extending device of design, utilizes the elasticity of skin to make it the extension that progressively stretches, and reaches wound covering at last.Its technical scheme is: skin extending device is made up of sleeve, inner core and cover tube, and cylinder core is contained in the sleeve, and inner core one end has turncap, and turncap cooperates with the flange of sleeve termination.The fit system of turncap and flange is that flange is the upper toothed ratchet of periphery, and the ratchet on the turncap is stuck in the ratchet teeth groove.The inner core other end has supporting pin to stretch out the key seat of cover tube bottom.At the column part that inner core overlaps with sleeve, the threading via hole of several spacings 5-10 millimeter is arranged on inner core and the sleeve.Suit the cover tube that has the axially open gap in the sleeve outside.

The use of skin extending device can be removed skin transplantation from or with the misery of Vessel Skin Flap wound surface, reduce risk of infection, shortens convalescence, alleviates patient economy burden, does not stay simultaneously or dwindles more back cicatrix, stays appearance comparatively attractive in appearance to the patient.

4, description of drawings: Fig. 1 is the structural representation of skin extending device.Fig. 2 is the cutaway view of the A-A section of Fig. 1.

5, the specific embodiment: human body skin has elasticity, and healthy skin can be done stretching appropriateness, that be interrupted, and tensile skin can be bred the effect that reaches skin extension, skin area expansion gradually by histiocyte.Skin extending device utilizes this characteristic of skin skin that body surface is damaged progressively to be extended to close up then and sews up.Thereby abandoned traditional skin transplantation or from body Vessel Skin Flap wound surface.Skin extending device shown in Figure 1 is made up of sleeve 6, inner core 5 and cover tube 3, and cylinder core is contained in the sleeve, and inner core one end has turncap 1, and turncap cooperates with the flange 2 of sleeve termination.Fit system is that flange is the upper toothed ratchet of periphery, and the ratchet on the turncap (10) is stuck in the ratchet teeth groove.360 degree of the best aliquot circumference of number of detents are with the size of a ratchet skin that the position is extended of convenient metering revolution.The inner core other end has supporting pin 8 to stretch out the key seat 7 of cover tube bottom.At the column part that inner core overlaps with sleeve, the radially threading via hole 4 of 8 spacing 5-10 millimeters is arranged on inner core and the sleeve.Suit the cover tube 3 that has axially open gap 9 in the sleeve outside.Several stretching lines of stretched skin pass the through wires hole on sleeve and the inner core, and then load onto the cover tube of tape spool to opening, the stretching line is stretched out from axially open, and cover tube is bunched in the stretching line of stretched skin below the skin extending device by axially open, thereby makes extensor be in the wound top.In illustrated embodiment, 8 ratchets are arranged on flange.Turncap whenever revolved a ratchet, and the stretching line promptly is pulled, and was wrapped in the inner core circumference by axially open 9, the telescopic through wires hole 4 of cover tube, respectively with both sides skin to 1/8 of middle stretching inner core circumferential length.To the skin injury wound of different parts, can make the skin extending device of different length, band varying number through wires hole with different sizes.

Claims (2)
