On the other hand, the measuring marking ruler provided by the embodiment of the disclosure is particularly suitable for detecting marks on symmetrical parts and three-dimensional appearance, and can flexibly, simply, quickly and accurately measure, analyze and mark lines on the three-dimensional outline of the whole body, so that the pre-operation measuring mark is simplified, and the pre-operation design time is shortened; on the basis, errors of measured sizes and actual sizes are reduced, the operation difficulty of doctors is effectively reduced, the operation can be safely, effectively and smoothly performed, and the operation efficiency is further improved.

In this embodiment, the measuring marking ruler includes a shaft 10 and a marking assembly 20, the shaft 10 is used for placing the measuring marking ruler in a range to be measured, and the marking assembly 20 is used for marking lines in the measuring range by taking the shaft 10 as a center. Wherein, the marking assembly 20 comprises a housing 21 sleeved on the shaft 10, and the housing 21 can rotate on the shaft 10.

In this embodiment, a handle is further provided on the top of the shaft 10, which facilitates the use of the measuring marking ruler.

In this embodiment, the shaft 10 may include a cylindrical rod body, and the housing 21 is directly sleeved on the rod body to rotate; optionally, the shaft 10 is made of plastic. Therefore, the whole weight of the measuring marking ruler can be reduced, and the use is convenient; optionally, the shaft 10 is made of stainless steel. Therefore, the strength of the measuring marking ruler can be increased, the measuring marking ruler is not easy to damage, and the service life is long.

In the present embodiment, since the shaft 10 is used to place the measurement marking ruler in the range to be measured, and directly abuts the skin of the patient or the clothing of the patient. If the shaft lever 10 is made of plastic or stainless steel, in the actual use process, the contact area between the bottom of the shaft lever 10 and the patient is small, so that the pressure on the contact position with the patient is large, and discomfort and even pain can be caused to the patient. To this end, as shown in connection with fig. 2, in some embodiments the measurement marking ruler further comprises: and a pad 12 disposed at the bottom of the shaft 10. Effectively reduces the discomfort caused by the shaft lever 10 to the patient, and further reduces the pain.

In this embodiment, the pad 12 may comprise a sponge ball bonded to the bottom of the shaft 10 by using glue. Because the sponge ball has the characteristics of heat preservation, heat insulation, sound absorption, shock absorption, static prevention and the like, a certain buffering effect can be achieved, and then discomfort to a patient generated by the bottom of the shaft lever 10 can be relieved to a certain extent through the sponge ball.

Optionally, the sponge ball is fixed at the bottom of the shaft lever 10 by using a rubber sleeve, the rubber sleeve has certain elasticity, the sponge ball is plugged into one end of the rubber sleeve, and the other end of the rubber sleeve is sleeved at the bottom of the shaft lever 10, so that the sponge ball is fixed at the bottom of the shaft lever 10.

In this embodiment, the pad 12 may further include other pad bodies with buffering function, which can reduce the discomfort of the patient caused by the bottom of the shaft 10 to some extent, and is not limited herein.

In the above implementation, the discomfort to the patient that the bottom of the shaft 10 may be created by changing the area of the pad 12. Here, the area of the pad 12 may be increased so that the contact area with the skin of the patient or the clothing of the patient is large, and thus the pressure becomes small.

In some embodiments, the pad 12 includes a pad body and a receptacle disposed on the pad body, the receptacle on the pad body is configured to be inserted into the bottom of the shaft 10, and the pad body has an area larger than the bottom of the shaft 10, such that the pad body abuts against the skin of the patient or the clothing of the patient, and the discomfort of the patient caused by the bottom of the shaft 10 can be reduced compared to the case where the bottom of the shaft 10 abuts against the patient.

In the above embodiment, the marking assembly 20 is a line marking in the measuring range with the shaft 10 as the center. The marking assembly 20 includes a housing 21 sleeved on the shaft 10, the housing 21 can rotate on the shaft 10, and a measuring belt 30 capable of extending or retracting is further disposed in the housing 21, a marker 40 at the end of the measuring belt 30, and after the shaft 10 is fixed, the measuring belt 30 is pulled out and marked at a target position by the marker 40.

In order to enable the housing 21 to rotate on the shaft 10 and to enable the measuring tape 30 to be extended or retracted within the housing 21. As shown in fig. 3 and 4, in some embodiments, a shaft hole 24 is provided in the middle of the housing 21, and is sleeved on the shaft 10 through the shaft hole 24, and an installation space is configured inside the housing 21; the marker assembly 20 further includes: the rebound structure 22 is disposed in the installation space, the rebound structure 22 is connected with the measuring tape 30, and the measuring tape 30 can be extended or retracted from the housing 21 by the elasticity of the rebound structure 22. The orientation of the marker assembly 20 to be measured can also be adjusted at will by the use of the shaft bore 24 in conjunction with the shaft 10.

In this embodiment, the housing 21 may include a cylinder with a hollow middle portion, and the hollow structure is a shaft hole 24 of the housing 21, and the shaft hole 24 is sleeved on the shaft 10, so as to ensure that the housing 21 rotates on the shaft 10.

In the present embodiment, an installation space is configured inside the housing 21, and the resilient structure 22 of the marking assembly 20 is disposed in the installation space, where the resilient structure 22 is used to provide a resilient force to the measuring tape 30, so as to ensure that the measuring tape 30 can be extended or retracted from the housing 21. In some embodiments, rebound structure 22 comprises a spiral spring. The spiral spring is a plane spiral spring, and the plane spiral spring is a spring which winds an elongated material with a uniform section into a plane spiral shape, so that the winding number is large, the deformation angle is large, and more energy can be stored in a smaller volume.

In the present embodiment, the side of the shaft hole 24 contacting the shaft 10 is an inner side wall, and the outer side wall of the shaft hole 24 is a side wall disposed in the installation space. Because the middle part of the plane scroll spring is of a hollow structure, when the plane scroll spring is arranged in the installation space, the middle part of the plane scroll spring is contacted with the outer side wall of the shaft hole 24, and the plane scroll spring winds around the outer side wall of the shaft hole 24 as the circle center, so that the plane scroll spring can store more elastic potential energy. The tip of the flat spiral spring is connected to the measuring tape 30, and thus the measuring tape 30 can be extended or retracted from the housing 21 by elastic force.

In order to make the actual measurement distance more clear during the actual measurement, in some embodiments, the measuring tape 30 is provided with graduations. The graduations on the measuring tape 30 can be seen clearly from the length of extension of the measuring tape 30, so that the distance of the surgical site from the shaft 10 is clear.

Since the measuring tape 30 is extended or retracted from the housing 21, in the above-described process, if the material of the measuring tape 30 is soft, there may be a case where the measuring tape 30 is stacked in the housing 21. In some embodiments, as shown in connection with fig. 3, the inside of the housing 21 is configured with a spiral passage 23 centered on the installation space, one end of the spiral passage 23 communicates with the installation space, and the other end of the spiral passage 23 communicates with the outside, wherein the measuring belt 30 moves within the spiral passage 23. The spiral channel 23 can limit the movement area of the measuring belt 30, so that the measuring belt 30 can be smoothly extended or retracted from the housing 21.

In this embodiment, the installation space is in communication with the spiral channel 23, so that the resilient structure 22 can be connected to the measuring tape 30, and further can drive the measuring tape 30 to extend or retract smoothly from the housing 21. The spiral channel 23 may have a planar structure or a three-dimensional structure, and it is sufficient to ensure that the measuring belt 30 moves in the spiral channel 23.

Since the measuring tape 30 of the marking assembly 20 is measured only in the circumferential direction, it is inconvenient to use if the detection marking is performed in a three-dimensional appearance. As shown in connection with fig. 1 and 2, in some embodiments, a plurality of first limiting structures 11 are disposed on the outer side surface of the shaft 10 from top to bottom at intervals, a second limiting structure 25 is disposed on the inner side surface of the shaft hole 24, and the second limiting structure 25 overlaps the first limiting structure 11; wherein, pressing or pulling the housing 21 can overlap the second limiting structure 25 with the different first limiting structure 11 to adjust the position of the marking assembly 20 on the shaft 10.

In the present embodiment, the shaft hole 24 of the housing 21 is rotatable on the shaft 10. The first limiting structure 11 is a first annular clamping protrusion, is arranged along the circumferential inner side surface of the shaft lever 10, and is provided with a plurality of limiting structures from top to bottom; the second limit structure 25 is a second annular clamping protrusion, and is circumferentially arranged along the inner side wall of the shaft hole 24, and the first annular clamping protrusion and the second annular clamping protrusion are in lap joint. The second annular detent can rotate under the limitation of the first annular detent when the housing 21 is rotated.

In this embodiment, the protruding surfaces of the first annular detent protrusion and the second annular detent protrusion are circular arc shapes, so that the position of the marking assembly 20 on the shaft 10 can be conveniently adjusted. Here, taking the shaft lever 10 provided with three first annular engaging projections as an example, the first annular engaging projections a, b and c are respectively from top to bottom. At this time, the second annular clamping protrusion is overlapped with the first annular clamping protrusion b, and when the position of the marking component 20 on the shaft lever 10 needs to be adjusted, a certain force is needed to lift the shell 21, so that the second annular clamping protrusion is separated from the first annular clamping protrusion b and overlapped with the first annular clamping protrusion a; when the position of the marking assembly 20 on the shaft 10 needs to be adjusted, a certain force needs to be used to press the housing 21, so that the second annular clamping protrusion is separated from the first annular clamping protrusion b and is overlapped with the first annular clamping protrusion c.

Optionally, in the foregoing embodiment, the first limiting structure 11 may be an annular groove structure, the second limiting structure 25 may be an annular convex structure, or the first limiting structure 11 may also be an annular convex structure, and the second limiting structure 25 may be an annular groove structure, or other forms of first limiting structure 11 and second limiting structure 25 that are adapted.

When the measuring marking ruler is not used, the measuring marking ruler is convenient to store and place. As shown in connection with fig. 4 and 5, in some embodiments, the housing 21 is further provided with an opening for extending or retracting the measuring tape 30, and a clamping portion 26 is formed at the opening, and the marker pen 40 is clamped on the clamping portion 26. In this way, the marker pen 40 can be fixed to the housing 21, and the marker pen 40 can be removed from the engagement portion 26 when necessary.

In this embodiment, the marker pen 40 is a pen with a cylindrical structure, and the clamping portion 26 is adapted to the structure of the marker pen 40, so as to ensure that the clamping portion 26 can be clamped with the marker pen 40. Here, the structure of the engaging portion 26 needs to be adapted to the shape of the marker pen 40. Specifically, if the cross section of the marker 40 is triangular or square, the cross section of the engaging portion 26 is triangular or square accordingly.

To further secure the marker pen 40, as shown in connection with fig. 4, in some embodiments, the snap-fit portion 26 includes a channel structure with snap-fit tabs 27 disposed at the notches of the channel structure. The marker pen 40 may be further secured by the snap tab 27.

In this embodiment, the clamping portion 26 includes a slot structure, two clamping protrusions 27 are disposed at a slot of the slot structure, the two clamping protrusions 27 are symmetrically disposed, and the marker 40 is clamped by the two clamping protrusions 27, so as to prevent the marker 40 from being separated from the clamping portion 26.

In the present embodiment, since the measuring tape 30 is always subjected to the elastic force of the elastic structure 22 at the time of actual measurement, if it is desired to retain the projecting amount of the measuring tape 30 at this time, it is necessary to ensure that the elastic force of the elastic structure 22 does not retract the measuring tape 30 immediately after the releasing of the measuring tape 30. To this end, as shown in connection with fig. 1 and 5, in some embodiments, the marker assembly 20 further includes: the limiting rubber sleeve 50 is sleeved on the measuring belt 30; wherein the stop collar 50 snaps into the opening to limit movement of the measuring tape 30.

In this embodiment, when the extension amount of the measuring tape 30 needs to be reserved, the stop gum cover 50 is moved to the opening of the housing 21, the stop gum cover 50 can seal the opening, and the elastic force of the rebound structure 22 is resisted by the pressure of the stop gum cover 50 on the measuring tape 30, so that the movement of the measuring tape 30 is limited.

The above description and the drawings illustrate embodiments of the disclosure sufficiently to enable those skilled in the art to practice them. Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others. The embodiments of the present disclosure are not limited to the structures that have been described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof.
