FIG. 4 shows an example of the electronic unit according to the present embodiment, in which (a) is a schematic front view and (b) is a schematic perspective view when viewed from above. The electronic unit will be explained below based on FIGS. 2 to 4.

As shown in FIG. 1, an electronic unit 1 according to the present embodiment is attached to the distal end side of an insertion section 101 of an endoscope apparatus 100. As shown in FIG. 2, the electronic unit 1 includes a main body 10 molded from resin (phenol resin, epoxy resin, polyimide resin, bismaleimide triazine resin), ceramics, etc., and a sensor 20 attached to the tip side of the main body 10. , two light source parts 21 attached to the distal end side so as to sandwich the sensor 20 therebetween, and a plurality of terminals 30. The terminal 30 further includes a first terminal portion 31 disposed on the distal end side of the main body 10, and a second terminal portion 32 disposed on the rear end side opposite to the distal end side.

The sensor 20 grasps the state of a target site within the body, and if it is a camera, it will take color images. The light source unit 21 irradiates the target region with electromagnetic waves such as visible light so that the sensor 20 can accurately capture an image. The terminal 30 is a contact point that electrically contacts the sensor 20 and the light source section 21 with an electric wire 50 described later. Note that the electric wires 50 are inserted into the insertion portion 101 in a bundle.

Here, in order to make the explanation easier to understand, the positional relationship of the main body 10 will be defined. As shown in FIG. 3, a portion disposed at the distal end of the insertion portion 101 is referred to as a distal end portion 11, and a portion opposite to the distal end portion 11 is referred to as a rear end portion 12. Further, the direction from the front end portion 11 to the rear end portion 12 will be referred to as front and rear, and the direction perpendicular to that direction (perpendicular to the plane of the paper in FIG. 3A) will be referred to as upper and lower.

Note that each structure will be explained using the terms "first", "second", etc., but these words do not specifically limit the positional relationship, but are words used to explain the structure in an easy-to-understand manner. The two-terminal portion and the second terminal portion may be described as the first terminal portion.

As shown in FIG. 3, positioning portions 14 and 15 are provided on the distal end side of the main body 10 so as to extend toward the distal end from the first terminal portion 31 (distal end surface 13d) in which the four terminals 30 are arranged. , 16 are provided. Specifically, in a front view (when viewed from the distal end side) (see FIG. 3(b)), the positioning section 14 is provided so as to extend from the left end of the first terminal section (the distal end surface 13d). A positioning part 15 is provided to extend from the right end of the first terminal part, and a positioning part 16 is provided to extend from the upper end of the first terminal part. The right side surface 13a of the positioning section 14, the left side surface 13b of the positioning section 15, and the bottom surface 13c of the positioning section 16 form a recessed sensor storage section 13A.

As shown in FIGS. 2 and 3, the sensor 20 is attached to be housed in the sensor housing 13A, and is electrically connected to four terminals 30 arranged on the distal end surface 13d.

Further, on the distal end side of the positioning part 14, a light source bottom surface 13g on which two terminals 30 are arranged, a left side surface 13e for the light source, and a bottom surface 13c of the sensor positioning part 16 form a recessed light source storage part. 13B is formed. Similarly, on the tip side of the positioning portion 15, a light source bottom surface 13h on which two terminals 30 are arranged, a left side surface 13f for the light source, and a bottom surface 13c of the positioning portion 16 form a recessed light source storage portion 13C. is formed.

Each light source section 21 is attached to the tip end of the positioning sections 14 and 15, respectively, and arranged on the light source bottom surface 13g and the light source bottom surface 13h so as to be stored in the light source storage sections 13B and 13C. It is electrically connected to a plurality of terminals 30. That is, each light source section 21 is attached to the light source storage sections 13B and 13C formed at the tip of the positioning sections 14 and 15. In this embodiment, the light source bottom surface 13g and the light source bottom surface 13h also constitute the first terminal portion. That is, in this embodiment, the light source terminal 30 and the sensor terminal 30 are arranged at different positions in the front-rear direction.

Here, the material constituting the terminal 30 is not particularly limited as long as it has conductivity, but examples include brass, cupronickel, beryllium copper, titanium copper, zirconium copper, iron-containing copper, Corson alloy, and tin-containing copper. Examples include high copper alloys containing.

As described above, since the sensor 20 is installed so as to be stored in the sensor storage section 13A, the sensor 20 can be easily positioned during the assembly process, and the sensor 20 can be prevented from falling off. can. As a result, the work efficiency of the sensor mounting process can be improved.

Similarly, each light source section 21 is attached so as to be stored in the light source storage sections 13B and 13C, respectively, so that the light source section 21 can be easily positioned in the assembly process, and the light source sections 21 can be easily positioned. etc. can be prevented. As a result, the work efficiency of the process of attaching the light source section 21 can be improved.

In addition, as shown in FIGS. 4(a) and 4(b), two light source units 21 are arranged adjacently on both sides of the sensor 20 so as to be almost in contact with each other, and when viewed from the front (when viewed from the tip side) By arranging the distal end of the sensor 20 and the distal end of the light source section 21 so that they are almost flush with each other, the width and height can be made compact, and the electronic unit 1 can be made more compact. can do. Note that by locating the tip of the light source section 21 at the rear of the tip of the sensor 20, it is possible to widen the field of view of the sensor 20.

In this embodiment, the sensor 20 is a camera, and the light source section 21 is an LED light source. Further, the sensor 20 may be a CCD (Charge Coupled Device) camera, but a CIS (CMOS Image Sensor) camera, which is more compact than a CCD camera, is used. A CIS camera can form an image on a light receiving element using a very small equal-magnification lens.

Next, the relationship between the terminals of the electronic unit 1 will be explained. FIG. 5 is a circuit diagram showing the relationship between the terminals of the electronic unit according to the present invention.

The circuit diagram shown in FIG. 5 is an example of electrical connection between the terminals 30 arranged in the first terminal part 31 and the second terminal part 32, and only shows the terminals 30 and the conductive wires 33. This circuit is applied when the sensor 20 is a CIS camera and the light source section 21 is an LED light source. Note that the conducting wire 33 is formed three-dimensionally inside the main body 10, so that the conducting wire 33 for the CIS camera and the conducting wire 33 for the LED light source will not be short-circuited.

A CIS camera is composed of a power supply (+), data, clock, and GND (ground, -). The power supply terminal 30V1 of the first terminal section 31 and the power supply terminal 30V2 of the second terminal section are electrically connected by a conductive wire 33. The last digits "1" and "2" mean that they are arranged on the first terminal section 31 side and on the second terminal section side, respectively. The same applies below, and the data terminals 30D1 and 30D2, the clock terminals 30C1 and 30C2, and the GND terminals 30G1 and 30G2 are electrically connected by conductive wires 33, respectively.

Further, the LED light source is connected to a power source and GND, and a power terminal 30LV1 on the first terminal section 31 side and a power terminal 30LV2 on the second terminal section 32 side are electrically connected by a conductor 33, and GND is also connected in the same way. GND terminals 30LG1 and 30LG2 are electrically connected with a conductive wire. In this embodiment, there are two LED light sources, but since they can be wired in parallel or in series on the circuit, only one power terminal 30LV2 and one GND terminal 30LG2 on the second terminal section 32 side are required. It has become.

FIG. 6 shows the arrangement of the terminals 30 exposed from the main body 10. As shown in this figure, in this embodiment, there are four terminals 30 for the sensor 20 and two terminals 30 for the light source section 21. In the first terminal portion 31, eight terminals 30 are arranged as shown in FIG. 6(a). On the other hand, in the second terminal portion 32, six terminals 30 are arranged as shown in FIG. 6(b). Further, in the second terminal section 32, four terminals 30 are arranged at the upper part, and two terminals 30 are arranged at the lower part. That is, the number of terminals arranged in the second terminal section is different between the upper and lower parts. It goes without saying that the number of terminals 30 differs depending on the type of sensor 20, the number of light source sections 21, etc.

Here, the circuit formed by the terminal 30, the conductive wire 33, etc. may be mounted on a substrate and embedded in the main body 10, or may be mounted when the main body 10 is molded. For example, the module-type main body 10 can be formed by partially exposing the terminals 30 and embedding a circuit in the main body 10 using a 3D printer or the like. Alternatively, a module-type main body 10 may be formed by providing a hole for a circuit board in the main body 10, inserting the circuit board into the hole, and filling the gap with an adhesive. Since the circuit board can be formed from insulating ceramics or the like which is harder than resin, the strength of the main body 10 can be improved by using ceramics or the like. The exposed shape of the terminal 30 can be selected from circular, rectangular, etc., and the terminal 30 can be selected from pads, lands, etc. that are body parts for soldering.
<Arrangement of terminals 30>

The terminals 30 of the first terminal section 31 are arranged at different positions for the sensor 20 and for the light source section 21. That is, the terminals 30 for the sensor 20 are arranged on the tip side end surface 13d to form one array, and the terminals 30 for the light source section 21 are arranged on the bottom surface 13g for the light source formed at the tips of the positioning sections 14 and 15, 13h (see FIG. 3 and FIG. 6(a)). By configuring the electronic unit 1 in this manner, the depth dimension of the main body 10 (the dimension from the front end to the rear end of the main body) can be made compact.

The same applies to each terminal 30 of the second terminal portion 32, and when viewed from the rear end portion 12 side, one array is arranged at the upper part and the other array is arranged at the lower part (see FIG. 6(b)). . Rather than arranging them in a horizontal row, they are arranged in different positions vertically, and by reducing the number of terminals arranged horizontally, the left and right width dimensions can be made more compact. Here, by devising the arrangement relationship between the sensor 20 and the light source section 21 and the arrangement position of each terminal 30 in the first terminal section 31 and the second terminal section 32, the electronic unit 1 can be miniaturized to about several millimeters. It can be realized.
<Soldering work efficiency>

The electronic unit 1 is a more compact product, and the width of the terminal 30 is only about 0.2 to 0.3 mm. If the quantity can be mass-produced, it is possible to mechanically control soldering, but it is extremely difficult to solder manually. In this embodiment, the number of terminals 30 arranged in the first terminal part 31 and the second terminal part 32 is divided into different numbers for the front and back and the top and bottom of the main body 10, thereby preventing short circuits during soldering, etc. This clarification prevents incorrect assembly and improves the efficiency of assembling small parts.

In the second terminal portion 32, the number of terminals 30 arranged on the upper side of the main body 10 is greater than the number of terminals 30 arranged on the lower side. This takes advantage of the fact that the vertical cross-sectional shape of the main body 10 is flat at the top, but semicircular from the side to the bottom along the inner diameter of the insertion portion 101. In other words, the main body 10 has a shape that is wide near the circular center and becomes narrower as it approaches the periphery (lower part). By effectively utilizing the shape of the main body 10 and accepting the dimensions secured by the sensor 20 and the light source section 21 as one of the constraints, the electronic unit 1 can be made more compact, and at the same time, the size of the soldering terminal can be reduced. Since the width of 30 can be made larger, the efficiency of soldering work is improved.

Furthermore, in the second terminal section 32 of this embodiment, the partition wall section 40 is provided between each terminal 30, so that short circuit between the terminals can be prevented and the soldering work efficiency can be further improved. In the first embodiment shown in FIG. 6(b), the partition wall 40 is a vertical wall that stands up on the side of the terminal 30 toward the top or bottom of the main body 10, and in the second embodiment shown in FIG. It is a cylindrical wall (cylindrical wall) surrounding 30 in a circular shape (the cross-sectional shape of the hollow part is circular). Note that the shape of the embodiment is not particularly limited as long as the partition wall portion 40 is provided. Each terminal 30 of the second terminal portion 32 is electrically connected to an electric wire 50, but the electric wire 50 is easily moved and unstable during operation. By providing the partition wall 40, the position of the electric wire 50 is stabilized, and work efficiency including positioning and soldering of the electric wire 50 can be improved.

Note that the cross-sectional shape of the hollow portion of the cylindrical wall is preferably a tunnel type or a semicylindrical shape. If the cross-sectional shape of the hollow part of the cylindrical wall has such a shape, the electronic unit 1 can be made more compact.

Here, in the cylindrical partition part 40 of the second embodiment of the partition part 40, by providing a tapered part 41 with a larger inner diameter toward the inlet, hot air generated by a heat gun or the like during reflow soldering can easily enter the cylindrical part. (See FIG. 7(c)).

The electronic unit 1 is easily completed by electrically connecting the sensor 20 and the light source section 21 to the module-type main body 10 described above by soldering or the like, and the electronic unit 1 and the electric wire 50 are electrically connected by soldering or the like. The electronic unit 1 functions by connecting it to. For soldering, reflow soldering is particularly preferred for the first terminal section 31 in terms of work efficiency, but either normal soldering or reflow soldering can be selected for the second terminal section 32. The electric wires 50 that have been electrically connected to the electronic unit 1 are bundled, inserted into the insertion section 101, and connected to the operation section 102 using a connector or the like.

Power (power) is supplied from the control box 104 via the electric wire 50 inserted into the insertion section 101. Further, information from the sensor 20 is transmitted to the control box 104 via the electric wire 50, and output to the monitor 105 as necessary. For example, an image captured by a CIS camera is converted into an electrical signal and transmitted as image data. The power supplied from the control box 104 turns on the light source section 21, making it easier to take an image of the sensor 20, etc. The light source section 21 can be turned on and off using the control box 104.

FIG. 8 shows an example of the distal end side of the insertion section of the endoscope apparatus of FIG. 1, in which (a) is a schematic front view and (b) is a schematic cross-sectional view taken along the line AA in (a). The structure of the distal end of the insertion section will be explained based on FIG. 8.

In addition to the electronic unit 1, a forceps channel 200 for a treatment tool is opened at the tip of the insertion section 101, and the electronic unit 1 is compact, allowing cleaning without increasing the tube diameter of the insertion section 101. An air/water channel 201 can be installed to send out gas or liquid for use. Since the electronic unit 1 is small, the tube diameter of the insertion section 101 can be reduced, and the burden on the patient when the insertion section 101 is moved within the body can be reduced, thereby providing an endoscopic device 100 that can contribute to minimally invasive medical care. can.

Further, by configuring the electronic unit 1 in this way, by changing the arrangement positions of the terminals 30 arranged in each of the first terminal part 31 and the second terminal part 32, the main body 10 can be By distributing the front and rear depth dimensions and the number of terminals 30 arranged in the second terminal section 32, the left and right width dimensions of the main body 10 can be made compact, so a more compact electronic unit 1 can be realized. By preventing short circuits and incorrect assembly during electrical connection work such as soldering, the efficiency of assembly work can be improved.

The endoscope apparatus 100 includes the electronic unit 1 described above. By configuring the endoscope device 100 in this way, the outer diameter of the insertion section 101 can be further reduced by attaching the smaller electronic unit 1, and minimally invasive medical care can be realized.

The endoscope apparatus 100 is also configured to include an insertion section 101, an operation section 102 connected to the insertion section 101, a control box 104 and a monitor 105 electrically connected to the operation section 102 via a cable 103. may be configured. By configuring the endoscope device 100 in this way, the operation section 102 can be used to reduce the burden on the patient by using the insertion section 101 with a suppressed outer diameter, and power is supplied to the electronic unit 1, allowing the insertion section 101 to be used for purposes inside the body. The site can be illuminated and imaged.
