Description

Technical Field

[0001] This disclosure relates to the field of medical device technology, and in particular to an endoscope. Background Technology

[0002] Endoscopes with insertion parts that can be inserted into body cavities, such as ureteropelvic endoscopes, bronchoscopes, biliary endoscopes, and cardiac endoscopes, are widely used for internal detection or treatment procedures.

[0003] An electronic endoscope with a headstock equipped with a camera module and an illumination device has been developed. For example, CN104812290A discloses an electronic endoscope including an insertion section, which has a top portion with a built-in camera unit, a curved portion, and a flexible tube portion from top to bottom. The top portion is provided with an observation window, an illumination window, and an opening communicating with a processing instrument channel and allowing the processing instrument to extend.

[0004] In existing endoscopes, the insertion section is typically constructed as a cylindrical structure, making accurate positioning of the headstock difficult. The headstock's orientation can only be determined when the illumination device within the headstock is lit, and assembling the various components of the insertion section is challenging. Furthermore, even after the insertion section is positioned and glued to the endoscope housing, a deviation in the positive direction of the image remains after assembly. Using other fixing methods (such as adding connecting rings) results in complex structures, difficult assembly, and higher costs. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model discloses an endoscope, including a tip base and a camera module assembled in the tip base; wherein, the tip base defines a longitudinal axis extending from the proximal end to the distal end; the tip base includes an opening, a working channel, and a transparent end face, the transparent end face having a non-arc portion and an arc portion; the arc portion is inclined from the non-arc portion toward the proximal end, the non-arc portion surrounds the opening, and the arc portion surrounds the working channel; the camera module includes an imaging module and a light source; the imaging module extends to the opening, and the light source is located in the projection area of ​​the arc portion perpendicular to the longitudinal axis; the light source is configured to emit light directly from the transparent end face.

[0006] The endoscope of this invention has an arc-shaped portion on the end face of the tip seat, which makes it easier to insert the tip seat into the body cavity and reduces trauma. Attached Figure Description

[0012] The endoscope disclosed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following detailed description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used for the purpose of conveniently and clearly illustrating the embodiments of this utility model.

[0013] like Figures 1 to 5 As shown, the endoscope includes a tip mount 10 and a camera module 20 mounted within the transparent tip mount 10. The transparent tip mount 10 defines a longitudinal axis extending from the proximal end to the distal end. The tip mount 10 includes an opening 11, a working channel 12, and a transparent end face 13, which has a non-arc portion 13a and an arc portion 13b. The arc portion 13b is inclined from the non-arc portion 13a towards the proximal end, with the non-arc portion 13a surrounding the opening 11 and the arc portion 13b surrounding the working channel 12. The camera module 20 includes an imaging module 21 and a light source 24. The imaging module 21 extends into the opening 11, and the light source 24 is located within a projection area of ​​the arc portion 13b perpendicular to the longitudinal axis. The light source 24 is configured to emit light directly from the transparent end face 13. By providing an arc portion on the end face of the tip mount, the endoscope facilitates insertion into the body cavity, reducing trauma.

[0014] As used herein, the term "proximal end" refers to the end that is closer to the operator during normal operation, and correspondingly, the term "distal end" refers to the end that is further away from the operator during normal operation.

[0015] The diameter of the proximal end of the tip 10 is less than or equal to 5.2 mm, and the diameter of the smallest circumscribed circle of the non-arc portion 13a is less than 3.3 mm. This reduction in size directly helps to reduce patient trauma.

[0016] The imaging module 21 includes a lens assembly and a CMOS module. The lens assembly and the CMOS module are bonded together to reduce the size of the imaging module 21.

[0017] The imaging module 21 has a cross-sectional area of ​​less than or equal to 3.61 square millimeters to reduce the size of the tip mount 10.

[0018] The imaging module 21 has a resolution of 1 million pixels or more to make the image clearer.

[0019] The terminal block 10 also includes a cavity 14, in which the camera module 20 is assembled along a single direction to avoid assembly errors.

[0020] The camera module 20 also includes a circuit board 22. The imaging module 21 and the light source 24 are connected to the circuit board 22. The circuit board 22 is assembled in the cavity 14 along a single direction to avoid assembly errors.

[0021] The imaging module 21 protrudes to the distal end of the opening 11 in order to form a high-definition image.

[0022] The arc-shaped portion 13b has a first arc-shaped portion and a second arc-shaped portion, the first arc-shaped portion surrounding the second arc-shaped portion, and the second arc-shaped portion surrounding the working channel 12. This construction of the arc-shaped portion 13b further increases the taper of the end face 13 of the tip seat 10, which further helps to reduce trauma to the patient.

[0023] The endoscope also includes a spiral tube 30 and a handle 40. The proximal end of the tip seat 10 is connected to the distal end of the spiral tube 30, and the proximal end of the spiral tube 30 is connected to the distal end of the handle 40.

[0024] The terms “first,” “second,” and “third” are not intended to indicate order or quantity; for example, a reference to a second element is not intended to limit the existence of a first element.

[0025] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] The singular forms “a,” “the,” and “the” used in this disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0028] Unless otherwise specified, the terms "multiple" or "a plurality of" in this disclosure and the appended claims refer to two or more.

[0029] Obviously, those skilled in the art can make various modifications and variations to the endoscope disclosed in this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
