Description
Technical Field
The application relates to a medical apparatus, in particular to a self-adaptive skin traction system in a large wound surface skin healing and growing process.
Background
After a patient has a trauma caused by a serious accident, the skin can shrink from the lacerated part, and after the wound operation, the skin edge at the lacerated part needs to be slowly and continuously pulled to gradually proliferate, so that the aims of re-covering the wound surface and recovering the recovery are fulfilled. The stretching process lasts for several weeks, and in the process, the magnitude and direction of the stretching force are precisely controlled from time to time, otherwise uneven skin growth or failure to stretch may result.
Some skin retractors have appeared, as cited document 1: CN104826219A, the principle is to pierce the puncture needle 34 into the skin at the edge of the wound, and then to slowly draw the puncture needle to the distance by using a three-set screw mechanism to pull the skin.
As also cited document 2: CN103654893B, this solution first sets anchor points on the skin, then tightens with a thin wire between the anchor points, and manually adjusts the degree of tightening.
The cited documents 1, 2 may be referred to as retractors of the first type, which are characterized in that the adjustment of the traction force according to the growth process of the skin is achieved by adjusting the mechanical force between the piercing points. However, the first type of retractor does not have the function of displaying the pulling force, the elastic force of the skin of people of different ages is different, the pulling force is changed only by adjusting the distance, and if the force value is not appropriate, the cortex is stressed too much and is broken or the cortex is not stressed enough to stimulate the growth after the first type of retractor is pulled for a period of time, and the rehabilitation failure still occurs.
Some solutions that can display the pulling force have appeared, as cited document 3: US10076386B2, which uses a torsion spring to tighten the pull wires of all anchor points, and determines the pulling force through a constant force spring, and displays the specific pulling force reading through the scale on the shell.
As also cited document 4: CN110432994A, this proposal uses a tension spring, which is pulled by a puncture needle or a steel wire that is inserted into the skin, and also visually displays the pulling force by a scale.
The citations 3 and 4 may be referred to as the second type of retractor and they are characterized by the fact that the pulling force is transmitted through the pulling wire, but this type of solution presents a new problem in that the pulling wire presses against the deep muscular layer of the wound, obstructing the blood flow and causing poor growth. Because human limbs have radian everywhere, for large wounds, the tensioned pull string presses arc muscles for a long time, and new injuries can be caused.

Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1-4, an adaptive skin stretching system according to the present application is characterized in that: comprises the steps of (a) preparing a mixture of a plurality of raw materials,
at least one of the tension force display parts,
the pulling force display part comprises a flexible inner cylinder 1,
a flexible outer cylinder 2 sleeved outside the flexible inner cylinder;
the flexible inner cylinder and the flexible outer cylinder can be matched in a sliding way;
the inner and outer cylinders are provided with end covers 3, and the insides of the two end covers are connected with springs 4;
scales are drawn outside the flexible inner cylinder or on the flexible outer cylinder, and the sliding distance can be displayed when the scales slide relatively;
when the spring is in the initial length, the displayed scale is a scale 0 point;
the outer sides of the two end covers 3 are provided with connecting parts 5;
at least one tension adjusting part 6 connected with the tension display part;
a pulling needle which is inserted into the pulled skin and has a bridge-shaped arching hanging part 9 connected with a pulling force display part or a pulling force adjusting part.
When the above scheme is used, the traction needle is firstly inserted into the edge to be pulled of the skin wound (see attached figure 4), then the traction force display part and the tension force adjusting part are hung on the hanging part of the traction needle, the length of the tension force adjusting part is adjustable, the length of the tension force adjusting part is changed to enable the spring in the traction force display part to reach the required tension force, and whether the proper tension force is reached is judged through scale reading.
In the course of several weeks of rehabilitation growth, the spring in the retractor can loosen with the skin growth, the actual tension can still be read from the reading, and the length of the tension regulator is changed to obtain the required tension again.
The matched inner and outer cylinders are flexible, so that the inner and outer cylinders can adapt to the radian of the human body on the surface of the human body in a self-adaptive manner, but the tensile force is not influenced, and the influence of the instrument on the human body is very low due to the cylindrical outer contour, so that the outer cylinder is superior to a pull wire or a similar scheme.
The scheme has only three elements in fact, greatly reduces the manufacturing difficulty, and simultaneously has very natural body feeling when a patient uses the scheme for a long time. The low number of components, i.e. the higher reliability, is particularly important in medical devices that are used snugly.
Further, the tension adjusting part is a chain with openable chain links.
The length of the open chain is very easy to adjust, and as can be seen from the attached figure 4, the open chain has the characteristic of flexible hanging, so that the scheme can be freely combined according to the specific situation of the wound.
The traction needle has been widely used in medical devices related to skin growth, as cited document 5: CN209518894U A skin traction needle. The novel skin care needle adopts a pulling needle with a protrusion, and the protrusion mainly prevents the needle body from sliding in the skin. Furthermore, the bulge is changed into a bridge-shaped arch, so that the anti-skid and convenient pulling and hanging are realized. The hanging part can be directly hung with the connecting part on the pulling force display part or can be bound by means of medical suture lines and the like.
Furthermore, the bridge-shaped arched hanging parts are uniformly distributed on the traction needle.
Furthermore, the inner barrel and the outer barrel are made of materials harmless to human bodies, such as medical rubber, medical silica gel and the like.
Furthermore, the inner cylinder and the outer cylinder are made of medical steel wires in a weaving mode.
Further, the chain may be a chain in which each link may be opened.
Further, the connecting part is a hook or a hanging ring.
Further, the spring is selected from a set of spare spring devices having a series of stiffness coefficients or lengths.
The adjustment span of the required tension is very large during the whole skin growth process, so that a group of springs with the same length but different stiffness coefficients or different lengths but the same stiffness coefficient can be matched, and different springs can be used in different traction stages to obtain different tension adjustment ranges. The spring is replaced to carry out rough adjustment, and then the tension adjusting part is used for carrying out fine adjustment.
Further, the skin stretching system may further include the following steps:
(1) penetrating at least one pulling needle into the skin of the wound margin to be pulled;
(2) searching two hanging parts which are connected with the upper line of the opposite traction needle and have the angle which is closest to the right angle with the included angle of the traction needle;
(3) the two hanging parts are connected with a traction force display part and a tension force adjusting part;
(4) the pulling force is adjusted by changing the number of the connected chain links of the pulling force adjusting part, and the pulling force numerical value displayed by recording and observing scales reaches the required value;
(5) and continuing the steps to arrange the drawing system on other hanging parts.
Taking the example of fig. 4, the trapezoidal wound is firstly arranged with a transverse pulling system, and the direction of the transverse pulling system is nearly perpendicular to the pulling needle represented by the dotted lines at the two sides, which is to ensure that the pulling force is displayed correctly; and then more pulling systems are deployed as needed.
Further, still include:
(5) and a pulling force display part and a pulling force adjusting part are added in the rest hanging parts and the connected chain links, so that each skin surface needing to be pulled is pulled.
(6) And adjusting the length of the tension adjusting part according to the tension displayed by each tension display part to obtain the required tension.
It is noted that the pulling force display part can be not only hung on the pulling needle, but also hung on another pulling force display part or other positions on the pulling system (for example, the pulling force display part can also be hung on the flexible outer cylinder), which brings great convenience to the arrangement of the pulling system, makes the pulling direction very flexible, can be designed according to the specific situation of the wound, and makes each pulling direction vertical to the pulling needle as much as possible.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
