Background technology
Researched and developed the feature that multiple therapeutic scheme improves skin.Aging and specified disease also influences these performances.These 2 have been caused following need for equipment, promptly can perhaps in order to assess aged influence, measure the device of the feature of skin before treatment and after the treatment or in the surveillance of disease process.
And in operating process, the otch of needed skin will change the feature of skin partly by forming cicatrix.If can measure the change of this position skin characteristic, caused misery can usefully quantize.A kind of preceding measurement along the tensile device of some directions that allow to perform the operation can also replace or the additional relevant clinical task of determining the optimum orientation of otch, thereby cicatrix is subjected to the possible stress of minimum.
WO 2004/086325 has described a kind of pick off, and described pick off comprises the flexible membrane of the part that forms pressure transducer.This device can not be measured the power along the direction that parallels with skin surface.Therefore, this device especially can not be measured the variation of the skin characteristic of cicatrix vicinity.
Summary of the invention
Particularly, the purpose according to device of the present invention is to satisfy above-mentioned needs.
According to the present invention, a kind of apparatus features that is used to measure the mechanical tension in biological tissue zone is that described device comprises:
-can be attached at least two pads of described tissue, and
-directly or utilize common matrix to connect at least one force transducer of described pad.
Described pad can be connected in described pick off by arm.
Described biological tissue can be a skin.
Advantageously, described pad can attach to skin by means of binding agent.
Described force transducer can comprise at least one deformeter.
At least one pad can have square shape.
At least one arm can extend to the midplane of described pick off orthogonally.
Advantageously, in the structure that has more than two pads, the angle between the described pad can be chosen as the function of parameter to be measured easily, is generally 30 °, 45 °, 60 ° or 120 °.

The specific embodiment
In whole description below the embodiment of apparatus of the present invention, for example " on ", the relational term of D score, " preceding ", " back ", " level " and " vertically " is assembled in the biological tissue at device according to the present invention, make an explanation when being in mode of operation.
Fig. 1 and Fig. 2 show according to device D of the present invention.Device D comprises two pads 1 and 2.Each pad 1,2 has equatorial bottom contact surface 1a, the 2a that is square shape basically.
Each pad 1,2 is fastened to along the first end of the arm 3,4 that is parallel to contact surface 1a, 2a extension.
The second end of each arm 3,4 is attached to force transducer 5.Therefore force transducer 5 connects two arms 3,4.
Pick off 5 is shapes of the elastic plate of essentially rectangular shape.Two looping pits, each end of pick off distributes one, allows it to be attached to arm 3,4.
Each arm 3,4 has screwed hole 3a, 4a, allows it to utilize hold-down screw 3b, 4b to be fastened to force transducer 5.
Can use following force transducer, it is based on wheatstone bridge and single pattern, and 1/2,1/4 or the deformeter of full-bridge, use 1,2,3,4 or 6 quantifiers.Under the situation of having used the pick off that utilizes 6 quantifiers, for example, 4 quantifiers are used for distortion, and 2 quantifiers are used for temperature-compensating.
It is contemplated that and use electric capacity even piezoelectric transducer.
The described device of following use:
The first, pad 1 and 2 is attached to the tissue T of examine.The connection that is connected to tissue T used based on double-sided tape or based on the binding agent (not shown) of glue.Binding agent is selected from those binding agents nontoxic to the individual.
Pick off 5 then is connected in following processor (not shown), and promptly described processor can be handled the information from pick off 5, and can provide and pad 1 and 2 between the proportional voltage of intensity of force.
Then, tissue T stands pick off predetermined deformation on every side by moving of any external device (ED) or main body.The distortion of having been induced in the tissue T causes the relative power between the pad, and pad is connected to force transducer by arm 3 and 4.
Power causes pick off 5 distortion relatively, can utilize deformation gauge to measure, and deformation gauge passes to computer with this information.
Compare by other tests that the T of homologue with identical predetermined deformation is carried out, the variation that can be taken place between two tests the mechanical performance of tissue T quantizes.
Especially, be used under the situation of skin, various application all are possible.
By the measurement of carrying out before surgical operation and behind the surgical operation is under the same conditions compared, because cicatrix has characterized the change of skin performance, can quantize caused misery, the character or the monitor of monitoring cicatrix are learnt again.
Before surgical operation, can also carry out a series of measurements, change the orientation of pick off 5 simultaneously by sliding contact surface 1a on skin and 1b, stand the direction of the power of minimum or maximum so that determine skin to constant distortion.
The measuring method of carrying out can be carried out in an identical manner simultaneously, so that deterministic force is maximum or minimum direction.
Then, this information can be used for the surgeon who carries out otch.
Another application is to determine the required distortion that puts on biological tissue, so that reach the given force between the pad.
Can come the geometry of modifier according to the function of using.
Fig. 3 and Fig. 4 illustration according to the embodiment of device of the present invention, wherein, reduced the location of the size of pad 1 and 2 with convenient means.
Fig. 5 and Fig. 6 illustration according to the embodiment of device of the present invention, wherein, increased arm 3 length in case pad 1 and 2 further place away from each other.Treat survey region have than large tracts of land or have wound or the condition of apparatus under, this may be useful.
Can also in single step, for example, measure along some directions by using the device with three pads shown in Figure 7.
Fig. 7 shows another embodiment, wherein, has used to have the device that is labeled as three pads of 10,11 and 12.Each pad 10,11 and 12 has roughly equatorial contact surface 10a, 11a and the 12a down of square shape.Each pad 10,11 and 12 is fastened to the arm 13,14 and 15 that attaches to force transducer 16,17,18.Angle between the normal of pick off 16,17,18 is 120 ° in this case.Described pick off is connected in common matrix 19, and it can or cannot attach to biological tissue.
Like this, described device can carry out orientation so that determine the tensile anisotropy of biological tissue along some directions.
