[0040] See also Figure 1 , Figures 4 to 6An embodiment of the utility model provides a visual module 100, which is applied to a drainage tube 200, and the drainage tube 200 includes an inlet and outlet channel; the visual module 100 includes a visual tube 110 and a visual component 120, the visual tube 110 is configured with a wire passage for allowing cables to pass through, and an installation cavity with an opening at one end connected to the wire passage, and the visual tube 110 can be inserted into the inlet and outlet channel; the visual component 120 is arranged in the installation cavity and exposed from the opening of the installation cavity, and the visual component 120 is used to obtain an image signal of the drainage position.

[0041] The present technical solution provides a visual module 100, which is applied to the drainage tube 200 to assist the doctor in detecting the specific situation of the drainage position, so that the doctor can accurately determine the puncture position. The visual tube 110 is used to be placed in the inlet and outlet channel of the drainage tube 200, driving the visual component 120 to move along the inlet and outlet channel, and then detecting the drainage position driven by the drainage tube 200. The installation cavity on the visual tube 110 is used to install the visual component 120, and the image signal of the drainage position is obtained through the visual component 120 to assist the doctor in detecting the drainage position, thereby improving the accuracy of the puncture. By setting up the visual module 100, it is helpful to improve the accuracy of the puncture, improve the quality of the drainage operation, improve the pre-sale of the operation, and increase the safety and effectiveness of the drainage operation.

[0042] like Figure 5 As shown, in one embodiment, the visual module 100 also includes a socket 130, which is connected to the visual component 120 through a cable. The visual tube 110 and the plug are used to connect the visual component 120 to the image processing system. The visual tube 110 includes an outer sheath and an internal cable. The outer sheath is placed in the inlet and outlet channel of the drainage tube body 210. The outer sheath material of the visual tube 110 can be TPU (thermoplastic polyurethane elastomer rubber), FEP (fluorinated ethylene propylene copolymer) or PE (polyethylene). Preferably, the outer sheath is selected from PE. The plug is used to connect the visual module 100 to the image processor.

[0043] like Figure 4 and Figure 6 As shown, specifically, the visual component 120 includes a packaging outer tube 121, a support seat 122, an image module 123 and a light source 124, the packaging outer tube 121 is provided with a accommodating cavity; the support seat 122 is arranged in the accommodating cavity; the image module 123 is fixedly supported on the support seat 122, and the image module 123 is used to obtain an image signal of the drainage position; the light source 124 is fixedly supported on the support seat 122, and is arranged adjacent to the image module 123, and the light source 124 is used to provide lighting for the image module 123.

[0044] The light source 124 is used to realize illumination of the observed part. The light source 124 can be LED lighting, which is arranged at the end of the package outer tube 121. The solution of optical fiber transmitting the cold light source 124 can also be adopted, and the external cold light source 124 is connected separately to realize illumination.

[0045] The packaging outer tube 121 is a tube used to package the image module 123, and can be made of stainless steel, titanium alloy, or biocompatible polymer material.

[0046] The support base 122 is used to place the image module 123 and the light source 124. The package support base 122 is a hollow structure, the light source 124 and the image module 123 are arranged at the front end, and a cable hole is reserved at the rear for transmitting image information and light source 124 signals.

[0047] like Figure 4 As shown, in one embodiment, the support base 122 includes a plurality of adjacent side surfaces, each of which is configured with a mounting groove, and each mounting groove is provided with at least one image module 123. By providing mounting grooves on a plurality of adjacent side surfaces of the support base 122, it is convenient to provide an image module 123 on each mounting groove, so that a visual component has a plurality of image modules 123, so that the drainage area can be detected from different directions and angles, thereby improving the detection efficiency and accuracy.

[0048] There is no limitation on the specific structure of the support base 122. In the present embodiment, the support base 122 is constructed as a square structure as a whole. A mounting groove is provided on the end face of the support base 122 which is away from the visual tube 110, that is, a mounting groove is provided on the end face of the front end of the support base 122, so that the image module 123 installed on the front end of the support base 122 can obtain the image information of the front end of the visual component 120. A mounting groove is provided on each of the four sides of the support base 122, and an image component is provided in each mounting groove, so that the four sides of the visual component 120 can obtain the image information corresponding to the corresponding side. In this way, the entire visual module 100 can detect the drainage position in five directions, thereby improving the efficiency of detection. It is understandable that each edge of the support base 122 should be rounded.

[0049] It should be noted that the mounting grooves on the support base 122 are connected to the wire passages on the visual tube 110 , so that the cables on the image module 123 and the light source 124 can pass through the wire passages and be connected to the socket 130 .

[0050] like Figure 6As shown, accordingly, a visual window corresponding to the mounting groove of the support seat 122 is provided on the side of the package outer tube 121, and the visual end of the image module 123 is provided in the visual window. By providing a visual window on the package outer tube 121, the visual end of the image module 123 can obtain image information of the drainage position from the visual window. It can be understood that the package outer tube 121 is made of titanium alloy or stainless steel and is itself opaque. Therefore, it is necessary to open a window on the package outer tube 121 so that the image component can detect the scene outside the package outer tube 121.

[0051] In this embodiment, the number of visible windows on the packaging outer tube 121 is set to correspond to the mounting slots on the support seat 122, so that the image module 123 installed on each mounting slot can detect the image information of the drainage position in the corresponding direction through the visible window.

[0052] It should be understood that five visual windows are provided on the package outer tube 121, and an image module 123 is provided at each visual window. Accordingly, at least one light source 124 is provided on each image module 123 to provide the required illumination for the image module 123 to obtain image information of the corresponding position. In addition, the overall shape of the package outer tube 121 is the same as that of the support seat 122, which is a roughly square structure. Of course, the edges of the package outer tube 121 are rounded.

[0053] like Figure 4 As shown, the visual module 100 further includes a first convex mirror 125, which is arranged in the visual window. By installing the first convex mirror 125 in the visual window, the visual field is expanded through the first convex mirror 125, so as to improve the detection range of the image module 123 at the corresponding position.

[0054] In one embodiment, the image module 123 includes an imaging element and a lens, and the imaging element is used to obtain an image signal of the drainage position; the lens is arranged at the front end of the imaging element to expand the field of view of the imaging element. The image module 123 is used to realize the acquisition of image signals, and includes a lens and an imaging element inside. The lens is a convex lens, which is used to achieve a larger viewing angle. The lens can be a single piece or a lens group. The imaging element can be a CCD camera or a CMOS camera. Preferably, the imaging element adopts a CMOS camera. Optionally, the CMOS camera models include OH0B and OV6946 produced by OMNIVISION (Haowei Technology). The lens system is arranged at the front end of the imaging element, and the image signal enters the imaging element through the lens, and is converted into an electrical signal, which is transmitted to the image processor through the rear visual tube 110 and the plug to realize the image display function.

[0055] like Figure 6As shown, in one embodiment, a plurality of light sources 124 are arranged around the imaging element. A plurality of light sources 124 are arranged around each imaging element to improve the lighting effect, thereby avoiding the blind area caused by poor lighting, and further improving the detection effect. In this embodiment, the imaging element is a square structure, and light sources 124 are arranged around the imaging element.

[0056] like Figures 1 to 3 As shown, an embodiment of the utility model further provides a drainage tube 200, and the drainage tube 200 includes the above visual module 100. The above visual module 100 is applied in the drainage tube 200 to assist the doctor in detecting the specific situation of the drainage position, so that the doctor can accurately determine the puncture position. The visual tube 110 is used to be placed in the inlet and outlet channel of the drainage tube 200, driving the visual component 120 to move along the inlet and outlet channel, and then the drainage position is detected under the drive of the drainage tube 200. The mounting cavity on the visual tube 110 is used to install the visual component 120, and the image signal of the drainage position is obtained through the visual component 120 to assist the doctor in detecting the drainage position, thereby improving the accuracy of the puncture. By setting the visual module 100, it is helpful to improve the accuracy of the puncture, improve the quality of the drainage operation, improve the pre-sale of the operation, and increase the safety and effectiveness of the drainage operation.

[0057] like Figure 2 As shown, in one embodiment, the drainage tube 200 includes a drainage tube body 210, a pipe joint 220, a drainage cavity branch 230, a drainage Luer joint 240 and a T-valve 250. The drainage cavity branch 230 is connected to the drainage tube body 210 through the pipe joint 220; the drainage Luer joint 240 is connected to one end of the drainage cavity branch 230 away from the drainage tube body 210; the T-valve 250 is connected to the drainage Luer joint 240; wherein the drainage tube body 210, the pipe joint 220, the drainage cavity branch, the drainage Luer joint 240 and the T-valve 250 are connected in sequence to form an inlet and outlet channel.

[0058] It can be understood that the inlet and outlet channels can be used for the visual module to enter and exit to obtain images of the drainage position and thus determine the lesion; they can also be used as drainage channels to drain the liquid in the drainage area out of the body.

[0059] The length of the drainage tube body 210 is set between 200-300 mm; the material of the drainage tube body 210 is any one of silicone, polyvinyl chloride or polyurethane. Preferably, the material of the drainage tube body 210 is silicone. The front end of the drainage tube body 210 is provided with a hydrophilic coating, for example, a silver coating. And a plurality of drainage holes 211 are provided on the outer peripheral surface of the front end of the drainage tube, so that the liquid to be drained flows from the drainage hole 211 into the inlet and outlet channel and flows out of the body.

[0060] The pipe joint 220 realizes the connection between the drainage tube body 210 and the drainage cavity branch 230. The material of the pipe joint 220 is engineering plastics such as ABS (acrylonitrile-butadiene-styrene copolymer) or HIPS (high impact polystyrene), or metals such as stainless steel and titanium alloy. The drainage cavity branch 230 is used to connect the drainage Luer connector 240. The material of the drainage cavity branch 230 is consistent with that of the drainage tube body 210. The T-valve 250 realizes the locking of the visual module 100 and the switch control of the drainage channel, and can also be used to realize the operation of drug injection. Its material can be PC (polycarbonate).

[0061] In this embodiment, the drainage tube body 210 is characterized in that a structure that cooperates with the visual module 100 is provided at its front end, and the visual module 100 can be conveniently placed in and out of the drainage tube 200. The matching structure 212 can be a concave-convex matching structure 212, and the inner cavity at the front end of the drainage tube body 210 is set to be concave, and the front end of the visual module 100 is set to be convex, so that the visual module 100 and the drainage tube 200 form a match, which facilitates the placement and withdrawal of the visual accessory.

[0062] like Figure 2 As shown, in one embodiment, the drainage tube 200 includes a drainage tube body 210, and a visible second convex mirror 2121 is provided at the end of the drainage tube body 210, and the visible end of the visual component 120 is provided at the second convex mirror 2121. The drainage tube body 210 is also characterized in that a convex lens structure is also provided at the portion where it cooperates with the image module 123 of the visual module 100, so as to form a "fish-eye effect" and achieve a larger field of view.

[0063] participate Figures 1 to 6 It is understood that the method of using the drainage tube 200 provided by the utility model is as follows:

[0064] When in use, the doctor first places the visual module 100 into the inlet and outlet channel of the drainage tube 200, and moves it to the matching structure 212 at the end of the drainage tube body 210, so that the visual module 100 and the end of the drainage tube body 210 are matched, and then the visual module 100 is locked using the T-valve 250. Subsequently, the doctor places the drainage tube 200 into the part that needs drainage under image guidance, and then takes out the visual module 100 to perform the drainage operation. During the drainage process, the visual module 100 can be placed again to confirm whether the drainage is completed, or to find other parts that need drainage, and adjust the drainage position until the drainage is completed. The drainage tube 200 provided by the embodiment of the utility model can help clarify the drainage position in the early stage of drainage, and can assist in exploring more lesions that need drainage during the drainage process, which helps to improve the accuracy of puncture, improve the quality of drainage surgery, improve the prognosis of drainage surgery, and increase the safety and effectiveness of drainage surgery.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0066] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
