Description

Technical Field

[0001] The utility model generally relates to the technical field of medical devices, and in particular to a visual flushing and suction device. Background Art

[0002] Irrigation and suction devices have long been widely used in surgical clinical procedures and are relatively common surgical instruments. Conventional irrigation and suction devices used in surgical clinical procedures do not have a camera function. Once inserted into human tissue, the device becomes blindly inserted, making it impossible to observe the tissue's real-time dynamics. Sometimes, to facilitate real-time observation of the tissue's dynamics and facilitate operation of the irrigation and suction device, the tissue must be expanded and a specialized endoscope inserted for observation. This operation is difficult and causes greater trauma to the patient's tissue.

[0003] Currently, there are flushing and aspiration devices that integrate a camera and an irrigation and aspiration device with an image display function. This allows doctors to directly view the display while operating, thereby achieving fast and accurate operation and causing less harm to the patient. For example, Chinese patent application number CN202311103394.9 is available. However, the existing design structure still has the following problems:

[0004] 1. The camera is located at the front end of the catheter, which is too close to the observation target, resulting in insufficient imaging distance and unclear images.

[0005] 2. The flushing and suction channel adopts a single-channel outlet, which has a large flow rate limitation, cannot achieve a good flushing effect, and is prone to blockage;

[0006] 3. The flushing and suction channels overlap, and they need to be operated alternately during use. This can easily flush the exudate remaining on the tube wall after suction back into the surgical space, increasing the chance of surgical infection. Utility Model Content

[0007] The present application provides a visual irrigation and suction device to solve the above problems.

[0008] The present application provides a visual flushing and suction device, comprising a shell, one end of which is connected to a catheter, a camera being provided at the end of the catheter away from the shell, and an integrated end head, the integrated end head being provided at the end of the catheter away from the shell, a cavity for accommodating the camera being provided in the middle of the integrated end head, the camera being provided in the cavity, an imaging lens being provided at the end of the cavity close to the lens of the camera, and one or more liquid channels being provided in the circumferential direction of the integrated end head.

[0009] According to some embodiments of the present invention, the end of the imaging lens away from the camera lens adopts a spherical surface.

[0010] According to some embodiments of the present invention, the imaging lens is made of transparent resin material.

[0011] According to some embodiments of the present invention, the imaging lens and the integrated end head are integrally formed.

[0012] According to some embodiments of the present invention, four groups of liquid channels are arranged at equal intervals along the circumference of the integrated end head.

[0013] According to some embodiments of the present invention, a data cable channel for laying the data cable of the camera is provided in the middle of the conduit.

[0014] According to some embodiments of the present invention, the space between the data line channel and the inner wall of the conduit is divided into two parts by a partition, one part is a flushing channel, and the other part is a suction channel.

[0015] According to some embodiments of the present invention, the flushing channel corresponds to the two liquid channels on one side of the integrated end head; the suction channel corresponds to the two liquid channels on the other side of the integrated end head.

[0016] According to some embodiments of the present invention, a protective cover is detachably provided at one end of the catheter.

[0017] It can be seen from the above technical solution that the advantages and positive effects of the visual flushing and suction device of the utility model are: by setting an integrated end head and setting a camera inside the integrated end head, the camera increases the imaging distance through the imaging lens, making the collected image clearer; at the same time, liquid channels are set in the circumferential direction of the integrated end head, and the flow rate can be increased by increasing the number of channels, and the occurrence of blockage can be reduced; the liquid channels can also be separated according to needs to achieve independent circulation and reduce the chance of surgical infection.

[0027] The following detailed description of the embodiments of the present application is provided in conjunction with the accompanying drawings and examples. The detailed description of the following examples and the accompanying drawings are intended to illustrate the principles of the present application, but are not intended to limit the scope of the present application. The present application may be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but rather includes all technical solutions within the scope of the claims.

[0028] The present application provides these embodiments to make this application thorough and complete, and to fully express the scope of this application to those skilled in the art. It should be noted that: unless otherwise specifically stated, the relative arrangement of parts and steps, the composition of materials, numerical expressions and numerical values ​​set forth in these embodiments should be interpreted as merely exemplary, and not as limiting.

[0029] It should be noted that, in the description of this application, unless otherwise specified, "plurality" means greater than or equal to two; the terms "upper," "lower," "left," "right," "inner," "outer," and the like, indicating directions or positional relationships, are intended solely to facilitate the description of this application and simplify the description, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0030] In addition, the terms "first," "second," and similar terms used in this application do not denote any order, quantity, or importance, but are simply used to distinguish different parts. "Perpendicular" does not mean perpendicular in the strict sense, but rather means within the tolerance range. "Parallel" does not mean parallel in the strict sense, but rather means within the tolerance range. "Include" or "comprising" and similar terms mean that the elements preceding the word include the elements listed after the word, and do not exclude the possibility of other elements being included.

[0031] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediary. A person of ordinary skill in the art will understand the specific meanings of the above terms in this application depending on the specific circumstances. When a specific device is described as being located between a first device and a second device, there may or may not be an intervening device between the specific device and the first or second device.

[0032] All terms used in this application have the same meaning as understood by one of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and should not be interpreted in an idealized or highly formal sense, unless explicitly defined as such herein.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] like Figures 1 to 5As shown in the embodiment, a visual irrigation and aspiration device includes a housing 1, one end of which is connected to a catheter 2, and an end of the catheter 2 away from the housing 1 is provided with a camera 3. The device also includes an integrated endpiece 4, which is provided at the end of the catheter 2 away from the housing 1. A cavity 40 is provided in the middle of the integrated endpiece 4 to accommodate the camera 3. The camera 3 is provided in the cavity 40, and an imaging lens 41 is provided at the end of the cavity 40 near the lens of the camera 3. One or more liquid channels 42 are provided circumferentially of the integrated endpiece 4. By providing the integrated endpiece 4 and arranging the camera 3 within the integrated endpiece 4, the imaging distance between the camera 3 and the observed object is increased through the imaging lens 41, making the image captured by the camera 3 clearer. At the same time, the integrated endpiece 4 is provided with liquid channels 42 in the circumferential direction. By increasing the number of channels, the liquid flow rate can be increased and the occurrence of blockage can be reduced. For example, if one liquid channel 42 is blocked, the other liquid channels 42 can still be used normally, ensuring smooth liquid flow. It is particularly noted that the cavity 40 for accommodating the camera 3 is arranged in the middle of the integrated end 4. This is only a rough description and should not be over-interpreted. Its arrangement above or below should be included in the protection scope of this application. Other structures of the visual flushing and suction device can adopt structures in the existing technology, and the specific structure is not limited here.

[0035] like Figure 5 As shown, in some embodiments of the present invention, the imaging lens 41 is spherical at one end of the lens away from the camera 3. The spherical imaging lens 41 conforms to the imaging law of a convex lens, that is, when an object is placed outside the focus, an inverted real image is formed on the other side of the convex lens. The real image has three types: reduced, equal, and enlarged. The smaller the object distance, the larger the image distance, and the larger the real image. When the object is placed within the focus, an upright and enlarged virtual image is formed on the same side of the convex lens. The larger the object distance, the larger the image distance, and the larger the virtual image. The spherical curvature of the imaging lens 41 can be determined according to actual conditions to achieve the best imaging effect.

[0036] In some embodiments of the present invention, the imaging lens 41 is made of a transparent resin material, which has the characteristics of good light transmittance, easy processing and manufacturing, good biocompatibility, and corrosion resistance.

[0037] like Figures 3 to 5 As shown, in some embodiments of the present invention, the imaging lens 41 is integrally formed with the integrated terminal 4. The imaging lens 41 and the integrated terminal 4 are integrally formed to facilitate production and processing, and the overall design makes the structure more compact and easy to assemble and use.

[0038] like Figures 3 to 5As shown, in some embodiments of the present invention, four groups of liquid channels 42 are arranged at equal intervals along the circumference of the integrated endpiece 4. Increasing the number of channels can increase liquid flow and reduce the likelihood of blockage. For example, if one liquid channel 42 becomes blocked, the other liquid channels 42 can still function normally, ensuring smooth liquid flow. It should be noted that the arrangement of four groups of liquid channels 42 at equal intervals along the circumference of the integrated endpiece 4 is merely a preferred embodiment of the present invention and does not limit the actual number.

[0039] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, a data line channel 20 is provided in the middle of the catheter 2 for routing the data line of the camera 3. The independent data line channel 20 allows the data line to be routed separately from the flushing and suction channels 23, thereby preventing the data line from contaminating the flushing fluid.

[0040] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, the space between the data line channel 20 and the inner wall of the catheter 2 is divided into two sections by a partition 21, one of which is an irrigation channel 22 and the other is a suction channel 23. This achieves independent circulation of the irrigation channel 22 and the suction channel 23, eliminating the need to operate them alternately during use. Exudate remaining on the tube wall after suctioning is prevented from re-entering the surgical space, thereby reducing the risk of surgical infection. It is particularly noteworthy that when implementing the above embodiments, independent switches and pipes can be used to connect the irrigation channel 22 and the suction channel 23, respectively, to achieve independent control of the irrigation channel 22 and the suction channel 23. Alternatively, the structure disclosed in Chinese patent application No. CN202311103394.9 can be adopted, in which the irrigation channel 22 and the suction channel 23 share a common section in the control section. However, since the section near the surgical space is an independent channel, less exudate remains on the tube wall after suctioning, also reducing the risk of surgical infection.

[0041] like Figure 6 As shown, in some embodiments of the present invention, the flushing channel 22 corresponds to the two liquid channels 42 on one side of the integrated endpiece 4; the suction channel 23 corresponds to the two liquid channels 42 on the other side of the integrated endpiece 4. Since both the flushing channel 22 and the suction channel 23 correspond to two liquid channels 42, blockage can be reduced. For example, if one liquid channel 42 becomes blocked, the other liquid channels 42 can still be used normally, ensuring smooth liquid flow.

[0042] like Figure 2As shown, in some embodiments of the present invention, a protective cover 5 is detachably provided at one end of the catheter 2. When the visual irrigation and suction device is not in use, the catheter 2 of the visual irrigation and suction device is wrapped with the protective cover 5 for protection, thereby preventing the external environment from contaminating or damaging the integrated end 4.
