Detailed Description
As shown in fig. 1, a skin preparation scope caliber before ear operation, including arc portion 1, the appearance of arc portion 1 is crescent, the size and the shape and the auricular root department looks adaptation of its inner arc, makes arc portion 1 can laminate in auricular root department. Both ends of arc portion 1 are equipped with through-hole 11, and through-hole 11 is the circular port, wears to be equipped with tape 2 in the through-hole 11, and tape 2 can select for use cloth chi or tape measure. The tape 2 has a width smaller than the diameter of the through hole 11. The two ends of the tape 2 are provided with limiting parts 21, and the size of the limiting parts 21 is larger than the diameter of the through hole 11. The limiting part 21 can be made of round rubber sheets and is adhered to two ends of the flexible rule 2 to prevent the flexible rule 2 from being separated from the through hole 11. The flexible rule 2 is provided with scale marks, the zero scale mark of the scale marks is positioned at one end of the flexible rule 2, and the measuring range of the flexible rule 2 is 6cm, because the width of the conventional ear skin preparation process is 6cm at most. When the spacing portion 21 of 2 one ends of flexible rule contacted with the side of arc portion 1, the zero scale mark of flexible rule 2 and the side parallel and level of arc portion 1, when pulling out flexible rule 2 to the direction of zero scale mark like this, just can observe the relative position of scale mark on the flexible rule 2 and arc portion 1 side to confirm the length that flexible rule 2 pulled out. For example, the width of the skin preparation required at this time is 2cm, one end of the flexible rule 2 is pulled firstly to enable the zero scale mark at the end part of the flexible rule 2 to be flush with the side surface of the arc part 1, then the other end of the flexible rule 2 is pulled to enable the 2cm scale mark on the flexible rule 2 to be flush with the side surface of the arc part 1, and therefore the flexible rule 2 is pulled out outwards by the length of 2 cm. The relative position between the tape 2 and the arc-shaped portion 1 can be fixed by means of a clip or the like, so that the tape 2 is kept in a state of being pulled out by 2 cm. The arc-shaped part 1 is then placed at the base of the ear of the patient, and the arc-shaped part 1 can be lightly hung at the base of the ear of the patient since the inner arc of the arc-shaped part 1 is adapted to the size and shape of the base of the ear. Then, the end of the tape 2 with zero graduation line is faced to the auricle, and the pulled-out part of the tape 2 is attached to the auricle, as shown in fig. 2. Thus, the distance from the zero graduation line of the end part of the flexible rule 2 to the ear root is 2cm, and the part from the zero graduation line of the end part of the flexible rule 2 to the ear root is the area needing skin preparation. The mark may be made in the skin preparation area by a color pen or the like. This completes the measurement and determination of the skin preparation area of the patient's ear.
The utility model discloses because the arc structure of arc portion 1 can well laminate with the auricle department, makes the measurement starting point of tape measure 2 be located auricle department for it is accurate with the determined skin preparation scope to measure. And medical personnel hold arc portion 1 when the operation, and can not direct application of force in patient's auricular root department, reduced the uncomfortable sense of patient in the regional in-process of confirming the preserved skin. The flexible rule 2 can be attached to the outline of the ear 3, so that the measurement is accurate, and the discomfort of a patient can be relieved.
After the tape 2 is pulled out by a desired length, in order to prevent the tape 2 and the arc portion 1 from being displaced from each other, it is necessary to fix the relative positions of the two by means of a clip or the like. However, the use of the clip is troublesome in operation. In order to solve the problem, the utility model discloses one side at through-hole 11 is equipped with locking hole 12. The locking hole 12 extends in a radial direction of the through hole 11 and communicates with the inside of the through hole 11. The axis of the locking hole 12 is perpendicular to the axis of the through hole 11. The locking hole 12 is internally provided with a locking column which can reciprocate in the locking hole 12, and one end of the locking column close to the through hole 11 can extend into the through hole 11 to abut against the tape 2. The locking column is in threaded connection with the inner wall of the locking hole 12. And a rotating handle is arranged at one end of the locking column far away from the through hole 11.
When the flexible rule 2 needs to be pulled, the handle is rotated to enable the locking column to move towards the direction far away from the through hole 11, so that the locking column is separated from the through hole 11, the locking column cannot limit the flexible rule 2, and the flexible rule 2 can be freely pulled in the through hole 11. When the tape 2 is adjusted in the pulled-out length, the tape 2 and the arc portion 1 need to be kept relatively fixed. The handle is rotated in the opposite direction, so that the locking column moves towards the direction of the through hole 11, the locking column extends into the through hole 11 until the locking column abuts against the flexible rule 2, the flexible rule 2 and the arc-shaped part 1 cannot move relatively, and the effect of locking the flexible rule 2 is achieved. This prevents the relative movement between the tape 2 and the arcuate portion 1, and keeps the length of the tape 2 drawn fixed. Can fix the relative position between arc portion 1 and the tape 2 fast through the locking post, prevent to shift between the two and lead to influencing the measurement, further improve the utility model discloses the measuring degree of accuracy to convenient operation is quick.
The arc portion 1 is covered with one deck soft layer on the one side that is close to the ear root, the intrados that is promptly, and soft layer can adopt soft materials such as silica gel, rubber or cotton to make. For avoiding direct contact of the curved portion 1 with the root of the ear. The ear root is fragile and sensitive, and the soft layer can reduce the uncomfortable sense that arc portion 1 brought when laminating with the ear root department.
As shown in fig. 1, two through holes 11 are respectively formed at both ends of the arc portion 1, and two tapes 2 are respectively disposed in the two through holes 11. When the device is used, the two flexible rulers 2 are pulled out by equal length according to the width of the required skin preparation, then the arc-shaped part 1 is attached to the position of the auricle, the two flexible rulers 2 are respectively attached to the upper part and the lower part of the auricle, so that the end parts of the two flexible rulers 2 are respectively positioned at the upper part and the lower part of the auricle, and as shown in fig. 2, the area from the connecting line between the end parts of the two flexible rulers 2 to the position of the auricle is the area of the required skin preparation. Simultaneous measurement at the upper and lower parts of the auricle to determine the preserved skin area can make the measurement more accurate.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
