Description

Technical Field

[0001] The present application relates to the technical field of medical instruments, and in particular to a distal end component of an endoscope and an endoscope. Background Art

[0002] With the rapid development of science and medical technology, the use of endoscopes for minimally invasive or non-invasive medical examinations and treatments has become widely popular. An endoscope generally consists of a handle, an insertion tube assembly, and a distal end, arranged from the proximal end (the end closest to the operator) to the distal end (the end away from the operator). The distal end typically includes a camera module and an illumination module. The illumination module illuminates the lesion area, allowing the camera module to capture images of the lesion.

[0003] In the related art, the lighting module is limited by space and cannot provide ideal lighting conditions for the camera module, thereby affecting the camera module's image acquisition effect on the lesions on the human body. Utility Model Content

[0032] See Figure 1 The front end component 100 of the endoscope provided in one embodiment of the present application includes a circuit board 110, a camera module 120 and at least one lighting module 130. The camera module 120 is arranged on the circuit board 110 and is electrically connected to the circuit board 110; at least one lighting module 130 is located on at least one side of the camera module 120; each lighting module 130 includes at least two light-emitting elements 131 electrically connected to the circuit board 110; at least two light-emitting elements 131 are arranged around the camera module 120. For example, Figure 1 In the embodiment shown, the lighting modules 130 include two, and the two lighting modules 130 are respectively located on both sides of the camera module 120 along the radial direction, where the radial direction is perpendicular to the axial direction of the camera module 120. Figure 1 In , radial direction can be left or right. Figure 1 In the embodiment shown, three light emitting elements 131 are provided on each lighting module 130. Of course, in other embodiments, the number of light emitting elements 131 can be set according to actual needs, for example Figures 2 to 6 As shown, the number of the light emitting elements 131 can be two to six, etc., and the specific number can be set according to the actual space.

[0033] The tip part 100 of the above-mentioned endoscope, by providing a plurality of light-emitting elements 131 surrounding the camera module 120, makes the distribution range of the light beam larger, thereby reducing the blind spot of the light beam, providing ideal lighting conditions for the camera module 120, and thus ensuring the image acquisition effect of the camera module 120 on the lesion of the human body. At the same time, the plurality of light-emitting elements 131 can be arranged as needed within a given limited space, so as to achieve the effect of obtaining greater brightness and less heat generation in the same space, thereby improving the imaging effect. The light-emitting element 131 includes but is not limited to LED. The circuit board 110 can be a hard PCB board, so it will not bend and deform during welding, which facilitates welding alignment, reduces the difficulty of the welding process, and improves production efficiency and product yield. In addition, the hard board can provide more stable support for the camera module 120 and the lighting module 130, thereby improving the structural stability of the imaging module.

[0034] See Figure 1 or Figure 2 As shown, in one embodiment, the lighting module 130 further includes at least one adjustment block 132, which is disposed on the circuit board 110. By disposing the adjustment block 132 between the light-emitting element 131 and the circuit board 110 to support the light-emitting element 131, the protrusion distance of the camera module 120 relative to the light-emitting element 131 is reduced, thereby reducing the possibility of the camera module 120 blocking the light of the lighting component, eliminating the blind spot of the light beam, providing ideal lighting conditions for the camera module 120, and ensuring the image acquisition effect of the camera module 120 on the human body lesions.

[0035] See Figure 1 As shown, in one embodiment, each lighting module 130 includes an adjustment block 132, and a plurality of light-emitting elements 131 are arranged in an array on the adjustment block 132. By arranging multiple light-emitting elements 131 on the same adjustment block 132, the number of adjustment blocks 132 to be processed is reduced, which helps to improve processing efficiency.

[0036] See Figure 2 As shown, in another embodiment, each of the lighting modules 130 includes a plurality of adjustment blocks 132 spaced apart on the circuit board 110, with at least one light-emitting element 131 disposed on each adjustment block 132. By providing multiple adjustment blocks 132, the positions of the light-emitting elements 131 can be arranged as needed within a given limited space, resulting in a more uniform light beam distribution, reduced blind spots, and improved imaging quality.

[0037] See Figure 2As shown, in one embodiment, each of the adjustment blocks 132 is provided with a light emitting element 131. In this way, the adjustment block 132 and the light emitting element 131 can be made as small as possible, achieving the effect of greater brightness and less heat generation in the same space, thereby improving the imaging effect.

[0038] In one embodiment, along the direction from the circuit board 110 to the light emitting element 131, at least two of the adjustment blocks 132 have different sizes. Figure 2 In the embodiment shown, the heights of the two adjustment blocks 132 may be different. For example, the height of the adjustment block 132 close to the camera module 120 is lower than the height of the adjustment block 132 away from the camera module 120. In this way, the possibility of the inner light-emitting element 131 blocking the outer light-emitting element 131 can be reduced, ensuring that each light-emitting element 131 can provide lighting effects for the camera module 120, thereby improving imaging clarity and imaging quality.

[0039] In one embodiment, the adjustment block 132 has a first connection surface and a second connection surface that are disposed opposite to each other, the first connection surface is electrically connected to the light emitting element 131, and the second connection surface is electrically connected to the circuit board 110. Figure 1 In the embodiment shown, the upper end surface of the adjustment block 132 is the first connection surface, and the upper end surface is provided with solder pads of different shapes corresponding to the positive and negative poles according to the arrangement of the light-emitting elements 131. The lower end surface of the adjustment block 132 is the second connection surface, and the lower end surface is provided with a group of solder pads of different shapes of the positive and negative poles corresponding to the position of the lighting module 130 on the circuit board 110.

[0040] In another embodiment, the adjustment block 132 includes a conductive member (not shown) that electrically connects the light-emitting element 131 to the circuit board 110. This arrangement achieves effective electrical connection between the light-emitting element 131 and the circuit board 110. Specifically, the two conductive members connect the positive and negative electrodes of the light-emitting element 131, respectively. Furthermore, the adjustment block 132 includes an insulating member (not shown) with conductive members attached to either side of the insulating member. By isolating the two conductive members, the insulating member can prevent short circuits in the light-emitting element 131.

[0041] like Figure 1 As shown, in one embodiment, the camera module 120 includes a lens 121 and an imaging chip 122. The imaging chip 122 is electrically connected to the circuit board 110, and the lens 121 is connected to the end of the imaging chip 122 facing away from the circuit board 110. The imaging chip 122 can be electrically connected to the circuit board 110 by welding or conductive glue, and the lens 121 is then bonded and packaged to the imaging chip 122 by conductive glue.

[0042] In some embodiments, the front-end component may also include a photosensitive element (not shown) located on the light-emitting side of the lens. The photosensitive element is electrically connected to the circuit board and is used to receive images generated by the lens for photoelectric conversion. Photosensitive elements include, but are not limited to, charge-coupled devices (CCDs) or complementary metal-oxide semiconductor sensors (CMOS sensors). The lens receives light from the lesion area. After being conditioned by the lens, the light is directed to the photosensitive element for photoelectric conversion, thereby outputting image information of the lesion area.

[0043] In some embodiments, the front-end component may further include a light shielding member (not shown), which covers both the circumferential outer side of the circuit board and the circumferential outer side of the lens to prevent light from entering the photosensitive element through the gap between the circuit board and the lens, thereby improving image display quality. The light shielding member may be a light shielding sleeve that provides light shielding, in which case the light shielding member may be a single-piece structure. Of course, the light shielding member may also include multiple light shielding sheets, which are bonded to the circumferential outer side of the circuit board and the circumferential outer side of the lens.

[0044] In one embodiment, the tip component includes a tip housing (not shown), which is provided with a mounting space for accommodating the camera module and the lighting module. In some embodiments, the main body of the tip housing can be a cylindrical structure, with an internal mounting space for mounting the camera module and the lighting module. The mounting space has an opening through which the lens receives light during use. The mounting space not only serves to mount the lens and light shield, but also provides a certain degree of protection for the lens and light shield, reducing the risk of damage to the lens and light shield.

[0045] In another embodiment, a working channel may be provided on the distal housing for passage of surgical instruments. To facilitate imaging by the camera module, the distal housing may also be provided with an exposure port or transparent window corresponding to the camera module. The working channel may be provided side by side radially on one side of the camera module. Of course, in other embodiments, the distal component may not include a working channel.

[0046] Alternatively, in one embodiment, during manufacturing, the front-end housing can be first injection molded, and then the camera module and lighting module can be installed in the installation space of the front-end housing. Finally, glue can be poured into the installation space to securely connect the front-end housing and the camera module. In another embodiment, the camera module and lighting module can be first fixed in the front-end housing mold, and then glue can be poured into the front-end housing mold. Finally, after curing and demolding, the front-end housing can be integrated with the camera module to form the front-end housing.

[0047] In some embodiments, the front-end component further includes a connector (not shown) electrically connected to the circuit board. The connector is used to electrically connect to the circuit board within the endoscope handle. Thus, during assembly, the front-end component circuit board and the handle circuit board can be electrically connected simply by plugging the connector into the circuit board within the handle, eliminating the soldering process and improving assembly efficiency.

[0048] In some embodiments, the front-end component further includes a temperature sensor (not shown), housed within the mounting space and configured to detect the temperature within the body cavity. The temperature sensor can be a non-contact optical fiber. The temperature sensor head is mounted on the front-end component and does not come into contact with the human body during use. The optical fiber is connected to the host computer via a cable, transmitting the measured results to the host computer for display.

[0049] In some embodiments, the front-end component further includes a pressure sensor housed within the mounting space for detecting pressure within the body cavity. The pressure sensor may be a contact-type pressure fiber optic. The pressure sensor is mounted on the front-end component and contacts the human body during use. The pressure fiber optic is connected to the host computer via a cable, thereby transmitting the measured results to the host computer for display.

[0050] Furthermore, one embodiment of the present application provides an endoscope (not shown) comprising the aforementioned distal end member of the endoscope. It is understood that the endoscope may further comprise a handle and an insertion portion, with the two ends of the insertion portion connected to the handle and distal end member, respectively. During use of the endoscope, the insertion portion may be inserted into a patient's body, and the light-emitting element may emit light to illuminate the lesion, thereby supplementing the lens with light. The lens is used to capture images of the lesion for diagnosis or treatment.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
