In order to solve the problem of inconvenient installation of the electronic component 140 in the conventional head end structure 1, the present application provides a sensing module 10, and the sensing module 10 is generally used in head end structures 1 of various specifications, and is finally applied to various endoscope products.

Referring to fig. 1 to 7, an embodiment of a sensor module 10 applied in a head end structure 1 is shown.

Referring to fig. 3 to 5, the sensor module 10 provided by the present application includes a mounting base 110, at least two electrical connectors 130, and at least two electronic components 140. The mounting base 110 has a first end 111 and a second end 112 opposite to each other in the length direction thereof, and the first end 111 is provided with at least two mounting portions 120; at least two electric connectors 130 are formed on the outer wall of the mounting seat 110 in a sheet shape through laser, the electric connectors are arranged on the mounting seat 110 in a one-to-one correspondence manner and correspond to the mounting parts 120, one ends of the electric connectors 130 are arranged on the corresponding mounting parts 120, and the other ends of the electric connectors 130 extend towards the second end 112; at least two electronic components 140 are correspondingly mounted on the mounting portions 120 one by one, and the electronic components 140 have electrical connection portions connected with the electrical connectors 130 in the mounting portions 120 at the positions where the electrical connection portions are located.

In the technical scheme provided by the utility model, the mounting seat 110 is provided with the mounting part 120 in advance in the forming process, and the mounting part 120 is provided with enough space for arranging the power supply connecting piece 130; the electric connecting piece 130 is formed on the mounting seat 110 in a laser mode, so that on one hand, a thin sheet shape can be formed, which not only helps to save consumables, but also helps to form a larger and more uniform electric contact surface by uniformly spreading; on the other hand, the stability of the connection between the electrical connector 130 and the mounting seat 110 is enhanced; when the electronic component 140 is mounted on the mounting portion 120, the electrical connection portion thereof can be connected to the electrical connection member 130 at the mounting portion 120, compared to the conventional operation of peeling and welding the thin signal transmission line, since the electrical contact area between the electrical connection portion and the electrical connection member 130 is large enough, peeling operation is not required, and whether welding is performed or not, a sufficient operation space and a good electrical contact effect can be formed, which helps to simplify the mounting process and improve the mounting yield. In addition, the mounting base 110, the electrical connector 130 and the electronic component 140 are integrally mounted to form a universal module, which can be universally used in the head end structures 1 with various specifications, and is further helpful to improve the processing efficiency of the product and reduce the manufacturing cost of the product.

The specific expression form of the mounting seat 110 is not limited in the present application, and may be a block, a box, a frame, or a plate according to actual needs. In the following embodiments, the mounting base 110 is in a block shape to provide a sufficient mounting space for the electrical connector 130 and the electronic component 140, and to facilitate the mounting of the sensing module 10 in the endoscope.

The mounting seat 110 has a first end 111 and a second end 112 opposite to each other in a length direction thereof, and a side surface connecting the first end 111 and the second end 112. It is understood that, when the mount 110 is substantially polygonal, the number of side surfaces thereof is set to be not less than three corresponding to the number of edges thereof; when the mount base 110 has a substantially cylindrical shape, the number of side surfaces thereof is set to one. The mounting seat 110 may also be provided with a special shape, for example, as shown in fig. 1, the mounting seat 110 has four side surfaces, specifically, two first side surfaces 113 oppositely arranged along the thickness direction thereof, and two second side surfaces oppositely arranged along the width direction thereof.

The two first side surfaces 113 are substantially straight surfaces facing each other, and the power supply connection member 130 extends. It will be appreciated that when the electrical connector 130 is disposed on the first side surface 113 in any suitable manner, the flat disposed first side surface 113 is more prone to spreading of the electrical connector 130 without requiring bending deformation of the electrical connector 130. In practical applications, each electrical connector 130 may be selectively disposed on at least one of the two first side surfaces 113. The two second side surfaces are substantially arc-shaped in order to be able to adapt as much as possible to the shape of the inner wall of the tube when mounted as a head end structure 1 into an insertion tube of an endoscope.

The mount 110 is provided with at least two mounts 120 at the first end 111 and/or adjacent to the first end 111. The specific representation of the mounting portion 120 is also not limiting. Since the mounting portion 120 is used for mounting the electronic component 140, when the electronic component 140 is selected, the representation of the mounting portion 120 can be specifically designed according to the actual situation of the electronic component 140, for example, when the electronic component 140 is relatively large in volume and is in a block shape, the mounting portion 120 corresponding to the electronic component 140 can be provided in a groove shape; when the electronic component 140 is substantially sheet-shaped, the corresponding mounting portion 120 may be provided in a planar shape that is adapted to the shape of the tape connecting surface; when the detection surface of the electronic component 140 needs to be exposed, for example, the corresponding mounting portion 120 can be set to be an open structure; on the contrary, when the electronic component 140 needs to be protected in a closed manner, for example, protection against magnetic, heat, water, etc., the corresponding mounting portion 120 may be configured as a closed cavity structure.

The number of the electronic components 140 in the sensor module 10 is matched with the number of the mounting plates, and generally, each electronic component 140 is designed with a matching mounting portion 120. Since the present application mainly exemplifies the application of the sensing module 10 in an endoscope, the electronic element 140 may be an illumination device such as an LED (light-emitting diode) or an imaging device such as a CMOS (Complementary Metal Oxide Semiconductor) in general. For ease of understanding, each electronic component 140 is defined below to include a first electronic component 140a and a second electronic component 140b, wherein the first electronic component 140a may be an imaging device as described above and the second electronic component 140b may be an illumination device as described above.

When the structure of each mounting portion 120 is determined, the electrical connection members 130 may be provided for the electronic components 140 according to the structure of the mounting portion 120 and the type of the corresponding electronic component 140. Each electronic component 140 is necessarily matched with at least one electrical connector 130. For ease of understanding, the electrical connector 130 corresponding to the first electronic component 140a is defined as the first electrical connector 130a, and the electrical connector 130 corresponding to the second electronic component 140b is defined as the second electrical connector 130b. For example, in the present embodiment, the first electronic component 140a is correspondingly configured with four first electrical connectors 130a, and the four electrical connectors 130 are respectively arranged on two first side surfaces 113 two by two. Each second electronic component 140b is correspondingly configured with two second electrical connectors 130b, which are also respectively disposed on the two first side surfaces 113.

In view of the above, the mounting portion 120 at least presents a plane, i.e., provides sufficient design space for the layout of the electrical connector 130. In a further aspect, the electrical connecting member 130 may be substantially configured as a sheet and attached to the outer surface of the mounting portion 120, on one hand, the electrical connecting member 130 configured as a sheet may be spread out with limited material as much as possible to form a sufficient electrical connection area, so as to facilitate electrical connection with the corresponding electronic component 140, such as soldering; on the other hand, the thickness of the adhesive on the mounting base 110 of the electrical connector 130 is reduced as much as possible without interfering with other members on the peripheral side, and the adhesive is exposed outside the mounting base 110, so that the handling is easy and the defect is easy to find.

In a specific application, the electrical connector 130 may be formed into a sheet structure by a process such as stamping, or in an embodiment, the electrical connector 130 is formed into a sheet structure by laser and directly attached to the mounting base 110. The laser method facilitates the formation of thinner electrical connector 130, and a more precise and more stable connection between electrical connector 130 and mounting base 110 can be achieved without additional mounting operations between electrical connector 130 and mounting base 110.

Electrical connector 130 generally includes a first conductive segment 131, a second conductive segment 132, and a third conductive segment 133 connected in series along a length thereof. Where first conductive segment 131 and third conductive segment 133 act as input and output segments for a signal and second conductive segment 132 acts as a transmission segment for a signal. In the present embodiment, the first conductive segment 131 is disposed to electrically connect with the electronic component 140. It will be appreciated that the electronic component 140 itself is typically provided with electrical docking portions, which typically represent, for example, electrical terminals, electrical welding contacts, signal transmission wire cores, and the like. Third conductive segment 133 is configured to be electrically connected to, for example, a control system of the endoscope, so as to transmit a control signal from the control system to electronic component 140 via third conductive segment 133, second conductive segment 132, and first conductive segment 131 in sequence; or vice versa, the sensing signal from electronic component 140 is transmitted to the control system via first conductive segment 131, second conductive segment 132, and third conductive segment 133 in sequence.

In view of the above, by providing first conductive segment 131 at mounting portion 120 of first end 111, alignment of the electrical interface with first conductive segment 131 can be achieved during mounting of operative electronic component 140 to mounting portion 120. It can be understood that when the function of the mounting portion 120 for limiting the electronic element 140 is strong enough, the electronic element 140 can be limited by the mounting portion 120, and at the same time, the stable electrical connection between the electrical butting portion and the first conductive segment 131 is completed. Generally, however, in order to prevent poor contact between the electrical contact and the second conductive segment 132, the electrical contact and the point conductive segment are fixedly connected by welding or the like.

The electrical connection between the third conductive segment 133 and the control system is not limited. In a specific application, the third conductive segment 133 may be used as a pin, or integrated into an electrical connector such as a plug, so as to facilitate quick connection with an electrical connection end of the control system.

In the present application, the first conductive segment 131 is disposed at the mounting portion 120 of the first end 111, and the second conductive segment 132 extends and guides the third conductive segment 133 to the second end 112 or a position close to the second end 112, so that the first conductive segment 131 and the third conductive segment 133 are sufficiently spaced apart, and good structural independence is achieved.

Based on the above, referring to fig. 3 and fig. 4, in an embodiment, each of the electronic elements 140 includes the first electronic element 140a and the second electronic element 140b as described above; the first end 111 is provided with a through groove 121 extending along the width direction thereof, and divides the portion of the mounting base 110 close to the first end 111 into two protruding columns 122, the through groove 121 and the protruding columns 122 respectively form the mounting portion 120, wherein the first electronic component 140a is inserted into the through groove 121, and the second electronic component 140b is provided on at least one of the protruding columns 122.

Since the first electronic element 140a as the imaging device is in a block shape with a relatively large volume, the corresponding mounting portion 120 is provided as the through groove 121, which is not only convenient for the limited mounting of the first electronic element 140a, but also does not shield the sensing surface of the first electronic element 140 a. The second electronic element 140b as a lighting device is generally in the form of a lamp panel, and has a relatively thin thickness, so that the corresponding mounting portion 120 is disposed as an end surface of the boss 122, which is not only convenient for performing limit mounting on the second electronic element 140b, but also can heighten the second electronic element 140b, so that a light emitting surface of the second electronic element 140b is as close as possible to a sensing surface of the first electronic element 140 a.

The second electronic components 140b may be disposed at least two and distributed on the two protruding pillars 122, and are sufficiently close to the first electronic components 140a, which contributes to the overall compact structure.

In view of the above, in an embodiment, the mounting seat 110 has the first side surface 113 of connecting the first end 111 with the second end 112, the first side surface 113 is being close to the second end 112 is sunken to form and is dodging groove 114, dodging groove 114 runs through the second end 112 sets up, the electric connector 130 is including the first electrically conductive section 131, the second electrically conductive section 132 and the third electrically conductive section 133 that connect gradually, at least the first electrically conductive section 131 is located correspondingly in the installation department 120, the second electrically conductive section 132 is attached at the first side surface 113, the third electrically conductive section 133 is located dodge in the groove 114, or pass through dodge groove 114 and extend to the second end 112 department. By providing the slot 114, a slot may be formed at the mounting base 110 near the second end 112, and the third conductive segment 133 is exposed, so as to facilitate the electrical connection between the third conductive segment 133 and the control system.

Further, referring to fig. 4, in an embodiment, an area of the first conductive segment 131 is larger than an area of the second conductive segment 132 connected thereto. The first conductive segment 131 is electrically connected to the electronic component 140, and the area of the first conductive segment 131 is set to be larger, so that an adequate electrical connection surface can be formed, which is favorable for operations such as welding between the first conductive segment 131 and the electrical connection portion, and the electrical connection area between the first conductive segment 131 and the electrical connection portion is large enough, which is favorable for stable electrical performance.

In addition, referring to fig. 5, in an embodiment, each of the electronic components 140 includes a first electronic component 140a and a second electronic component 140b, and two second electronic components 140b are disposed on two sides of the first electronic component 140 a; the electrical connector 130 connected to the first electronic component 140a is a first electrical connector 130a, and the third conductive segment 133 of the first electrical connector 130a is disposed in the avoiding groove 114; the electrical connector 130 connected to the second electrical component 140b is a second electrical connector 130b, and the third conductive segments 133 of the second electrical connectors 130b connected to two of the second electrical components 140b are connected at the second end 112. It can be understood that, in the four second electrical connectors 130b of the two second electrical components 140b, the third conductive segments 133 of the corresponding two second electrical connectors 130b are connected in parallel, which further contributes to improving the light emitting effect and stabilizing the performance. Also, the third conductive segment 133 of the first electrical connector 130a is disposed at the first side surface 113 (free of the groove 114) and the third conductive segment 133 of the second electrical connector 130b is disposed at the second end 112 such that the first electrical connector 130a is substantially close to but independently spaced from the second electrical connector 130b.

In addition, please refer to fig. 1 to 2 and fig. 6 to 7, the present application further provides a head end structure 1, where the head end structure 1 includes the sensing module 10, the connecting member 20, and the outer sleeve 30. Wherein, the connecting piece 20 is connected to one side of the mounting base 110, and a through hole 210 is arranged along the length direction of the connecting piece 20; the outer sleeve 30 is sleeved on the periphery of the sensing module 10 and the connector 20.

The through hole 210 can be communicated with an insertion tube of an endoscope after the head end structure 1 is applied to the endoscope to form a channel for medical instruments such as a snare, a lithotomy basket, medical forceps and the like to pass through and perform surgical operation on a focus part.

The connection mode between the connection member 20 and the mounting base 110 is not limited, and any suitable detachable connection mode may be adopted, such as bolt connection fixation, magnetic attraction fixation, buckle fixation, adhesion fixation, and the like. Referring to fig. 5 to 6, in an embodiment, one of the connection portions of the connecting member 20 and the mounting base 110 is provided with a protrusion 115, and the other is provided with a groove 230, and the protrusion 115 is in concave-convex fit connection with the groove 230. The specific shape of the protrusion 115 and the groove 230 may be set according to the specific installation manner of the connection member 20 and the installation base 110.

After the mounting base 110 is provided with the through groove 121 and the two protruding columns 122 as described above, the connecting member 20 is connected to one side of the mounting base 110, and can limit and shield the first electronic component 140a installed in the through groove 121 and the two second electronic components 140b installed on the two protruding columns 122 in the connection orientation.

It can be understood that, after the sensing module 10 is modularized, the sensing module can be used in various head end structures 1, and in order to increase the adaptability between the sensing module 10 and a specific endoscope insertion tube, the outer sleeve 30 can select a required specification according to actual needs. It is understood that the diameter of the outer sleeve 30 is at least large enough to fit over the outer side of the connector 20 and the mounting seat 110, and is equal to or larger than the total outer diameter of the assembly formed by the connector 20 and the mounting seat 110.
