Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to the outer Distraction Apparatus of the fixing skin of a kind of convenience.
Background technology
Clinical common skin wound, because of edge of wound overtension, directly can not draw the situation of stitching over to one's side.Needed to adopt the operation of skin-grafting or transfer of skin flap to repair, but wound is large, the hospital stays is long, medical expense is high in the past.The outer stretching technology of skin is introduced into this kind of wound being difficult to directly to sew up of clinical treatment in recent years.Principle is the loosening property and the ductility that utilize skin, uses outer Distraction Apparatus by the Pi Yuanxiang center tractive of wound both sides, progressively reduces wound, and final stitching eliminates wound surface.
The Distraction Apparatus of current employing is that independently pair of matched closes the tooth and button that use, tooth and deduction of points is not sewed up perpendicular to wound major axis and is fixed on the skin of both sides.According to the size of wound or wound surface, select 3 to 4 Distraction Apparatus.But the open defect that such Distraction Apparatus exists is that stress point is only limitted to, on the several point of longitudinal direction at wound edge, can produce following drawback: 1. stretching efficiency is low, and treatment time is long in use procedure; 2. stationarity is bad, affects skin healing; 3., because the skin of edge of wound often exists the unfavorable conditions such as inflammation, edema and scar hyperplasia, poor ductility, after inadequate stretching, skin texture is thinning, affects wound healing quality; 4. the skin that wound both sides are more and more healthy is effectively mobilized.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of convenient fixing, stationarity is good, and the outer Distraction Apparatus of stretching efficiency skin that is high, that alleviate patient suffering.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, the outer Distraction Apparatus of skin that a kind of convenience is fixing, comprise two fixing heads for being fixed on human body wound both sides, the equal correspondence of opposite side of two fixing heads is connected with multiple stator, the position of the stator of both sides is corresponding, quantity is equal and all towards wound, detachably be connected by connection strap between the stator of both sides, the two ends of connection strap are provided with one group of unidirectional tooth bar, two groups of tooth bar directions at two ends are contrary, and each group tooth bar is all towards the fixing head direction of respective end, the front end of each stator is provided with a fixing head, the inwall of fixing head is provided with the engaging tooth matched with the tooth bar of respective end, fixing head and stator all have the sewing hole for being fixed on skin.
Further, the number of this engaging tooth is 1 ~ 3.
Further, the length of this connection strap is 15cm ~ 20cm.
Further, the two ends of this connection strap are little trapezoidal in end.
The outer Distraction Apparatus of skin that a kind of convenience of this utility model is fixing, tool has the following advantages: 1. edge of wound is when stressed, and except longitudinal tissue is stressed, horizontal organization is at a distance also simultaneously stressed, and increase stress surface, stretching efficiency significantly improves; 2. reduce the probability that skin is torn, alleviate the misery of patient; 3. effectively mobilized normal skin wider outside edge of wound skin and edge of wound, make stretching effective, healing quality is higher; 4. one group of tooth bar that the two ends setting direction of connection strap is contrary, and this unidirectional tooth bar makes the end of connection strap can only towards the direction of this fixing head, connection strap both sides all can tractive on the one hand, ensure that stressed uniformity; On the other hand, when connection strap inserts, stationarity is good, ensure that effective healing of wound, and need not fix by auxiliary equipment.

Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, the outer Distraction Apparatus of skin that a kind of convenience of this utility model is fixing, comprise two fixing heads 1 for being fixed on human body wound both sides, the equal correspondence of opposite side of two fixing heads 1 is connected with multiple stator 2, the position of the stator 2 of both sides is corresponding, quantity is equal and all towards wound, detachably be connected by connection strap 3 between the stator 2 of both sides, the two ends of connection strap 3 are provided with one group of unidirectional tooth bar 3-1, two groups of tooth bar 3-1 directions at two ends are contrary, and each group tooth bar 3-1 is all towards fixing head 1 direction of respective end, the front end of each stator 2 is provided with a fixing head 4, the inwall of fixing head 4 is provided with the engaging tooth 4-1 matched with the tooth bar 3-1 of respective end, fixing head 1 and stator 2 all have the sewing hole 5 for being fixed on skin.Engaging tooth 4-1 is 1 ~ 3.The length of connection strap 3 is 15cm ~ 20cm.The two ends of connection strap 3 are little trapezoidal in end, conveniently insert.
The outer Distraction Apparatus of skin that a kind of convenience of this utility model is fixing, fixing head 1 and stator 2 are sewn on the skin of human body wound both sides, then connection strap 3 is inserted fixing head 4 from the front end of the stator 2 of both sides respectively, according to the practical situation of patient wound and skin, the end of connection strap 3 is drawn respectively from two ends, to determine a suitable tractive length, tooth bar 3-1 is meshed with engaging tooth 4-1, to be fixedly connected with bar 3.After a period of time is reduced in wound stretching, continue tractive connection strap, until wound healing.
The outer Distraction Apparatus of skin that a kind of convenience of this utility model is fixing, adopt fixing head 1 and stator 2 to sew up fixing simultaneously, the horizontal and vertical direction of wound both sides skin is made all to be subject to drawing power, effectively mobilize normal skin wider outside edge of wound skin and edge of wound, stretching is effective, and healing quality is higher.Tooth bar 3-1 is meshed with engaging tooth 4-1, and ensure that all can only move towards the fixing head 1 of side, place in the end of connection strap 3, avoid connection strap 3 adverse movement, stationarity is good, does not need just can be fixedly connected with bar 3 well by auxiliary equipment.Engaging tooth 4-1 is 1 ~ 3, an engaging tooth 4-1 and tooth bar 3-1 engage go wrong time, also have other engaging tooth 4-1 to work, ensure that stationarity.The length of connection strap 3 is 15cm ~ 20cm, meets the demand of patient in clinical.
