Description

  The present invention relates to a dimension measuring apparatus for measuring a desired dimension (thickness, diameter, etc.) of an object to be measured, and particularly to a dimension measuring apparatus suitable for measuring an object to be measured that is soft and easily deformed.

  2. Description of the Related Art Conventionally, as a dimension measuring apparatus that measures the thickness, diameter, and the like of a measurement object, there is a type that measures a measurement object by sandwiching the measurement object with a probe such as a caliper.

  Specifically, this caliper type dimension measuring device comprises a pair of measuring elements (a fixed measuring element and a moving measuring element) and a dimension display part (a scale part and a digital display part), and is a fixed measuring element in a separated state. The object to be measured is arranged between the movable measuring element and the movable measuring element, the operation part is operated, the moving measuring element is pressed against the measured object, and the measured object is sandwiched between the fixed measuring element and the moving measuring element. It is comprised so that the distance between measuring elements at the time of putting an object into the state may be shown as a measurement result on a scale part or a display part.

  This vernier caliper type dimension measuring device is excellent in that it is easy to operate and easy to carry, and can easily measure dimensions even in a fixed object to be measured.

  However, this caliper type dimensional measuring device, as described above, presses the measuring element against the object to be measured at the time of measurement. When the object to be measured is soft and easily deformed, the pressing of the measuring element The object to be measured is deformed and the exact dimensions cannot be measured.

  In addition, the degree of deformation changes depending on the degree of pressing (that is, depending on the amount of force applied by the operator), and the measured value also changes. Therefore, the reproducibility of the measurement is low, and the measurement result is low in reliability. It will be a thing.

  For this reason, when measuring an object to be measured that is soft and easily deformed, finely adjust the force applied to the operation unit so that the object to be measured is not deformed, and carefully move the probe to the object to be measured. It is necessary to make contact with each other, and such an operation is very troublesome, takes time for measurement, and causes a decrease in workability.

  In addition, a dimension measuring apparatus that solves the above-described problems in the caliper type dimension measuring apparatus and that can accurately measure the dimension of a measurement object that is soft and easily deformed has been proposed. Shown in Reference 1.

  The dimension measuring apparatus disclosed in Patent Document 1 includes a load measuring unit that detects a minute load, a lower base that is disposed on the load measuring device and on which an object to be measured is placed, and the lower base. And an upper base elevating means for elevating and lowering the upper base, and the upper base is lowered while the object to be measured is placed on the lower base. The distance between the upper base and the lower base when the upper base comes into contact with the object to be measured and the load measuring means detects a predetermined load value that does not cause deformation of the object to be measured. It is configured to detect and obtain the dimension of the object to be measured.

  However, the dimension measuring apparatus as described above has a complicated apparatus configuration and the apparatus itself is large, and cannot be easily carried like the caliper type described above, and a measurable object to be measured is placed on the lower base. There was a problem that was limited to the movable thing that can be.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  Operate the operating unit 3 to move at least one of the first member 1 and the second member 2 to open the measuring unit 4, and to place an object to be measured in the measuring unit 4 in the open state, By operating the operating unit 3, at least one of the first member 1 and the second member 2 is moved, the measuring unit 4 is closed, and the measuring unit 4 is brought into contact with the object to be measured.

  When the measurement unit 4 is in contact with the object to be measured, if the operation unit 3 is further operated (a force is continuously applied), an operating resistance is generated in the measuring unit 4 and is movable due to the generation of the operating resistance. Until the causal part 5 is deformed and the measuring part 4 comes into contact with the object to be measured, the movable part 6 that has moved along the receiving part 7 without approaching the receiving part 7 is transformed into the receiving part 7 by the deformation. When the operating resistance reaches a predetermined value, the contact portion 8 provided on the movable portion 6 contacts the receiving portion 7.

  When the abutting portion 8 abuts on the receiving portion 7, the dimension display portion 10 opens the measuring portion 4 when the abutting portion 8 abuts on the receiving portion 7. The distance between the provided first measuring element 9A and the second measuring element 9B is shown, and the desired dimension (thickness, diameter, etc.) of the object to be measured can be ascertained by reading the distance.

  That is, in the present invention, even after the object to be measured is sandwiched by the measuring unit 4 (for example, between the first measuring element 9A and the second measuring element 9B), the operation unit 3 continues to be operated (force is applied to the operating unit 3). In addition, the first measuring element 9A and the second measuring element when the operating resistance (reaction force of the pressing force by which the measuring unit 4 presses the object to be measured) generated in the measuring unit 4 sandwiching the object to be measured becomes a predetermined value. Since the distance from the measuring element 9B is displayed as a desired dimension of the object to be measured, the user simply operates the operation unit 3 by applying a force that generates an operating resistance of a predetermined value or more to the measuring unit 4 that sandwiches the object to be measured. It is possible to always measure the dimensions of the measurement object under the same conditions (the same sandwiched state) without varying the measurement conditions for the measurement object with an extremely simple operation.

  Therefore, like the conventional caliper type, the force applied to the operation unit 3 is finely adjusted so that the object to be measured is not deformed, and the measurement unit 4 is operated carefully so that the measurement unit 4 (for example, the first measuring element 9A and the like). There is no need to perform troublesome operations such as bringing the second measuring element 9B) into contact with the object to be measured, and the desired dimensions (thickness, diameter, etc.) of the object to be measured even if the operation unit 3 is manipulated without any effort. It becomes an epoch-making dimension measuring apparatus excellent in practicality that can accurately measure.

  Further, for example, if the predetermined value is set to a small value such that the object to be measured is not deformed as much as possible by the sandwiching of the measuring unit 4, that is, the movable factor part 5 is deformed with a force smaller than the force for deforming the object to be measured In other words, if the deformation resistance strength of the movable factor 5 is set smaller than the deformation resistance strength against the external stress of the object to be measured, the object to be measured is soft and easily deformed. However, since it is possible to accurately measure the desired dimensions of the object to be measured without deforming the object to be measured (with only a slight deformation), it is an epoch-making dimension that is even more practical. The measurement apparatus can be easily designed and realized. In the present invention, a minute deformation that does not affect the measurement is included in the undeformed state.

  A specific embodiment 1 of the present invention will be described with reference to FIGS.

  In this embodiment, the first member 1 and the second member 2 are provided, and at least one of them is movably provided, and the first member 1 or the second member 2 is moved by the operation of the operation unit 3. In the dimension measuring apparatus having a measuring unit 4 that operates and abuts so as to sandwich an object to be measured, one of the first member 1 and the second member 2 is movable by a movable factor 5 and a deformation of the movable factor 5. The movable portion 6 is provided, the receiving portion 7 with which the movable portion 6 abuts is provided on the other side, and the movable portion 6 has an abutting portion 8 that abuts against the receiving portion 7 and is used for measuring the dimension of the object to be measured. When the operation unit 3 is operated to operate the measurement unit 4 and sandwich the object to be measured, the operation unit 3 does not approach the reception unit 7 until an operating resistance is generated in the measurement unit 4. Relative to the installed state, and the force applied to the operation unit 3 When the part 4 comes into contact with the object to be measured and an operating resistance is generated in the measuring part 4, the movable factor part 5 is deformed and approaches the receiving part 7, and when the operating resistance reaches a predetermined value, the contact part 8 is configured to abut on the receiving portion 7, and the distance between the first measuring element 9 </ b> A and the second measuring element 9 </ b> B provided in the measuring unit 4 when the abutting portion 8 contacts the receiving unit 7. The dimension display unit 10 for displaying is provided.

  In addition, the present embodiment is a case of a scissors-type forceps type that is measured by holding operation or fingertip operation with one hand as shown in FIG. The operation unit 3 including the second operation unit 3B is provided on the proximal end side, the measurement unit 4 including the first measurement unit 4A and the second measurement unit 4B is provided on the distal end side, and the operation unit 3 is provided. The first measurement unit 4A and the second measurement unit 4B can be operated by performing an opening / closing operation in which the first operation unit 3A and the second operation unit 3B move relative to and away from each other by a gripping operation or a fingertip picking operation. By opening and closing, the first measuring element 9A and the second measuring element 9B are configured to move relative to and away from each other.

  Hereinafter, each component according to the present embodiment will be described in detail.

  The first member 1 of this embodiment is provided with a first operating portion 3A on the base end side via a movable factor portion 5 and a movable portion 6 movable by deformation of the movable factor portion 5, and is pivotally attached to the distal end portion side. The first measurement unit 4A is continuously provided on the distal end side of the pivotally attached portion.

  Specifically, the movable factor 5 has a configuration in which an appropriate elastically deformable member (for example, a metal member or a synthetic resin member) is formed in a C shape (may be a curved shape or an arc shape), and a measurement target. The member, thickness, and shape are appropriately set so as to be elastically deformed with a force smaller than the force that deforms the object to be measured, in other words, the deformation resistance strength is smaller than the deformation resistance strength of the object to be measured. It is arranged so that the opening (C-shaped separation part) is located inward, that is, is arranged so as to be convex outward, and one end is connected to the first member 1. The other end is connected to the movable portion 6.

  In addition, the movable portion 6 connected to the movable factor portion 5 protrudes toward the second member 2 facing the first member 1, and a contact portion that contacts and engages the receiving portion 7 at the tip portion. 8 and a pointer portion 11 constituting the dimension display portion 10 are provided.

  The abutting portion 8 provided on the movable portion 6 is formed in a tapered shape that engages with the shape of a receiving portion 7 described later, and is configured to project downward from the distal end portion of the movable portion 6.

  The pointer unit 11 is a position indicating the scale 0 of the scale unit 12 provided in the receiving unit 7 in a state where the measuring unit 4 is closed, that is, in a state where the first measuring unit 9A and the second measuring unit 9B are in contact with each other. The movable portion 6 is moved along the receiving portion 7 (scale portion 12).

  In addition, the first operation unit 3A has a configuration in which the first operation unit 3A is connected to the base end of the movable unit 6 (the side that is connected to the movable factor unit 5). In the present embodiment, the first operation unit 3A is used as the operation unit. 3 is formed in an annular shape so that the fingertip can be inserted so that the fingertip can be picked.

  In addition, the first measurement unit 4A provided on the distal end side projects a first measuring element 9A that contacts the object to be measured toward the distal end inward, and has a surface facing the second measurement unit 4B. It is the structure formed in the notch shape.

  That is, in this embodiment, when the measurement object is sandwiched by the measurement unit 4, the portions other than the first measurement element 9A and the second measurement element 9B that are in contact with the measurement object do not contact the measurement object. The cutout portion serves as a relief portion, and the first measuring element 9A (second measuring element 9B) is formed in a shape that preferentially contacts the object to be measured.

  Further, the second member 2 of the present embodiment is provided with the second operation part 3B on the base end side via the receiving part 7 and the pivot part at the tip part, and the second measurement part 4B at the pivot part. It is set as the structure which connected.

  Specifically, the receiving portion 7 is a direction substantially orthogonal to the length direction of the second member 2, in other words, a relative movement direction in which the receiving portion 7 and the movable portion 6 described above relatively move). The upper surface is formed in the shape of a saw blade that the contact portion 8 can contact and engage with.

  Moreover, it is set as the structure which provided the scale part 12 which comprises the dimension display part 10 in the front, and the scale part 12 displays the scale which shows the separation distance of the 1st measuring element 9A of the measurement part 4, and the 2nd measuring element 9B. The configuration is as follows.

  Moreover, the 2nd measurement part 4B provided in the 2nd operation part 3B and the front-end | tip part side is set as the structure similar to the 1st operation part 3A of the 1st member 1 mentioned above, and the 1st measurement part 4A.

  In the present embodiment, the first member 1 and the second member 2 configured as described above are arranged in an intersecting state so that the respective pivoting portions are overlapped with each other, and the shaft insertion formed in each pivoting portion. When the operating part 3 is opened and closed by a fingertip picking operation (or gripping operation) so that the first operating part 3A and the second operating part 3B move relative to and away from each other by inserting a shaft through the hole, the measuring part The first measuring element 9A provided on the first member 1 constituting the measuring unit 4 and the second measuring element 9B provided on the second member 2 are moved relative to each other by opening and closing operation 4.

  Further, in this embodiment, a configuration is provided in which a lock mechanism that holds the contact state of the contact portion 8 with the receiving portion 7 is provided.

  The locking mechanism of the present embodiment includes a locking claw portion 13 provided on the pointer portion 11 on the first member 1 side, and a concave groove portion 14 provided on the receiving portion 7 (or scale portion 12) on the second member 2 side. When the abutting portion 8 abuts on the receiving portion 7, the locking claw portion 13 falls into the concave groove portion 14 when the abutting portion 8 abuts on the receiving portion 7, and the operation of the operating portion 3 is stopped. When the application of force to the operation portion 3 is stopped, the return portion of the elastically deformable movable factor portion 5 causes the movable portion 6 (contact portion 8) to detach from the receiving portion 7, and this separation action. Thus, the locking claw portion 13 is locked to the side surface portion of the concave groove portion 14 to prevent the detachment action and maintain the contact state.

  In this embodiment, the first member 1, the movable factor portion 5, the movable portion 6, and the first operation portion 3A are integrally formed. However, for example, the movable factor portion 5 is configured to be replaceable, It is good also as a structure which can mount | wear with the suitable movable factor part 5 corresponding to the deformation-resistant strength of a measured object.

  The operation and effect of the present embodiment configured as described above will be described below.

  Opening the operation unit 3 to increase the distance between the first measuring element 9A and the second measuring element 9B, and disposing the object to be measured between the first measuring element 9A and the second measuring element 9B, In this state, the operation unit 3 is closed to move the second probe 9B relative to the first probe 9A (or the first probe 9A relative to the second probe 9B). Both the first measuring element 9A and the second measuring element 9B are brought into contact with the measurement site of the object to be measured.

  In the closing operation of the operation unit 3 until both the first measuring element 9A and the second measuring element 9B come into contact with the object to be measured, the movable part 6 (contact part 8) approaches the receiving part 7. Instead, it moves along the upper surface portion of the receiving portion 7 at a slight interval (almost constant interval) with respect to the upper surface portion of the receiving portion 7.

  When both the first measuring element 9A and the second measuring element 9B are in contact with the object to be measured, if the operation of the operation unit 3 is further continued (when force is continuously applied), the first measuring element 9A. And the second measuring element 9B abut on the object to be measured, an operating resistance is generated in the measuring unit 4, and the moving factor 5 starts to be deformed due to the occurrence of the operating resistance. When the deformation starts, the movable portion 6 moves toward a direction different from the moving direction along the receiving portion 7, specifically, a lower side substantially orthogonal to the moving direction and approaches the receiving portion 7. .

  When the movable part 6 moves due to the deformation (elastic deformation) of the movable factor part 5 and approaches the receiving part 7, a force for deforming the movable factor part 5 acts on the movable factor part 5, and the object to be measured Although the pressing force generated when the measuring unit 4 is sandwiched also acts, the movable factor portion 5 of the present embodiment employs a material having a deformation resistance smaller than the deformation resistance of the object to be measured. The causal part 5 is deformed, but the object to be measured is not deformed even when the measuring part 4 receives the pressing action (the pressing action by the first measuring element 9A and the second measuring element 9B).

  When the operating resistance generated in the measuring unit 4 reaches a predetermined value, the abutting portion 8 provided on the movable portion 6 abuts on the receiving portion 7, so that the abutting portion 8 is in contact with the receiving portion 7. The distance between the first measuring element 9A and the second measuring element 9B, that is, the desired dimension of the object to be measured is measured (acknowledged) by reading the value of the scale part 12 supported by the pointer part 11 of the dimension display part 10. can do.

  In the present embodiment, when the contact portion 8 is in contact with the receiving portion 7, the contact portion 8 is engaged and locked with the receiving portion 7, and the contact portion 8 of the movable portion 6 is engaged with the receiving portion 7. Since the movement in the moving direction before the contact is prevented, even if an attempt is made to further close the operation portion 3 by applying force to the operation portion 3, the movable portion 6 does not move, and the operation portion 3 cannot be closed. Therefore, the force applied to the operation unit 3 is not transmitted to the measuring unit 4, the measuring unit 4 does not close, and the separated state between the first measuring element 9A and the second measuring element 9B is maintained.

  In this way, the object to be measured, like the conventional caliper type, finely adjusts the force applied to the operation unit so as not to deform the object to be measured, and carefully moves the probe to the object to be measured. There is no need to perform a troublesome operation such as just abutting, and even if the operation unit 3 is operated casually, that is, for example, the operation unit 3 is strongly held with a strong force that deforms the object to be measured. The contact portion 8 contacts the receiving portion 7 due to the deformation of the movable factor portion 5 before the object to be measured is deformed, and the force applied thereafter is not transmitted to the measurement portion 4. A strong force that may deform the object to be measured is not transmitted to the measuring unit 4, and the desired dimensions (thickness, diameter, etc.) of the object to be measured can be accurately and reproducibly without deforming the object to be measured. It can be measured well.

  In the present embodiment, the dimension display unit 10 is configured to display an analog type including the pointer unit 11 and the scale unit 12, but the dimension display unit 10 may be configured to be a digital display. For example, a sensor may be provided in the receiving portion 7 so that the contact position of the contact portion 8 is sensed and the position is displayed.

  Further, in the scale unit 12, when it is sufficient to know the approximate dimensions, for example, a scale having a predetermined range (for example, a display in which the predetermined range is divided by color coding or the like) as shown in FIG. It is good also as a structure.

  Furthermore, the scale unit 12 may be configured to display other than the scale. Specifically, for example, when this embodiment is configured for organ thickness measurement when selecting the height of the stapler when anastomosing the organs, instead of the scale displaying the organ thickness on the scale portion 12 The configuration is such that the height of the stapler suitable for the thickness of the organ measured by the measurement unit 4 is displayed, and the user simply selects the stapler of the predetermined height pointed by the pointer unit 11 and the measured organ is easily measured. An optimal stapler for use in the anastomosis may be selected. As a result, it is possible to reduce as much as possible the occurrence of poor anastomosis due to erroneously selecting a stapler whose height does not match.

  A second embodiment of the present invention will be described with reference to FIG.

  The present embodiment is a case where the movable cause portion deformation prevention mechanism is provided in the movable cause portion 5 as shown in FIG.

  Specifically, the movable cause portion deformation prevention mechanism of the present embodiment is provided with a deformation prevention member 19 (in this embodiment, metal in the present embodiment) disposed in an erected state (opening portion) of the movable cause portion 5 formed in a C shape. (Adopting a rod-shaped member made of steel) acts like a tension rod, and prevents the elastic deformation of the movable factor portion 5.

  More specifically, as shown in FIG. 8, the deformation preventing member 19 is pivotally attached to a shaft attachment portion 20 provided at one end portion of the movable factor portion 5, and the other end portion is attached. It is configured to be detachably locked to a locking portion 21 provided at the other end of the movable factor portion 5, and this deformation prevention member 19 is locked to the locking portion 21 to both ends of the opening of the movable factor portion 5. The movable factor 5 is not elastically deformed (cannot be) by setting it between the parts, and the movable factor 5 is released by releasing one end from the latching part 21 and releasing the anchoring state of the latching part 21. It is comprised so that the part 5 may be in the state which can be elastically deformed.

  That is, since the movable part 5 is not deformed, the contact part 8 does not contact the receiving part 7, and the transmission of force from the operation part 3 to the measurement part 4 is not interrupted. A clamping tool or a pressing tool that can exert a strong clamping force or pressing force exceeding the value, and thus can not only measure the dimension of the object to be measured but also can clamp or press the object to be measured. Can also be used as an innovative dimensional measuring device with even more practicality.

  The rest of the configuration is the same as in the first embodiment.

  A specific third embodiment of the present invention will be described with reference to FIGS.

  In this example, the dimension measuring apparatus of Example 1 is configured as a forceps type for an endoscope as shown in FIG.

  More specifically, the first member 1 is formed in a U-shape, and the movable factor portion 5 and the movable factor portion 5 are formed on the distal end side (the entire proximal end portion side) of the longitudinal portion that is the proximal end portion side. The first operating portion 3A is provided via a movable portion 6 that is movable by deformation, and a pivot portion is provided at the distal end portion (the entire distal end portion) of the short side portion that is the distal end portion side. A rod connecting part 17 for connecting a rod 16 for operating the opening / closing operation of the measuring part 4 is provided.

  In the present embodiment, the movable factor portion 5 is configured to be replaceable, and an appropriate movable factor portion 5 can be attached in accordance with the deformation resistance strength of the object to be measured.

  Further, the second member 2 is formed in an L shape, and the second operation portion 3B is provided via the receiving portion 7 on the distal end side (the entire proximal end portion side) of the long side portion serving as the proximal end portion side. An elongated tubular member that is provided with a pivoting portion on the distal end side (entire distal end side) of the short side portion serving as the distal end portion side, and through which the rod 16 described above can be inserted into the distal end side of the pivoting portion. 18 is provided.

  In the present embodiment, the measurement unit 4 is provided at the distal end portion of the tubular member 18 provided on the second member 2, and the measurement unit 4 is operated by a gripping operation of the operation unit 3 or an opening / closing operation by a fingertip picking operation. The rod 16 connected to 1 moves forward and backward, and is configured to open and close by the forward and backward movement of the rod 16.

  The rest of the configuration is the same as in the first embodiment. In this embodiment, the lock mechanism is not shown.

  By configuring the dimension measuring device of the present invention into a forceps type for an endoscope as in this embodiment, for example, conventionally, when performing an anastomosis process using a stapler at the time of surgery, a body cavity to be anastomosed The thickness of the internal organs is measured sensorially by the tentacles etc. by the doctor, and the thickness cannot be measured accurately. However, by using this example, the thickness of the organ can be measured accurately and easily without deforming or scratching the organ.
