At the same time, there is no need to replace other measuring instruments, and the transparent cap can be used directly to complete the measurement, simplifying the operation process. And the number of instrument replacements is reduced, reducing the risk of cross infection.

[0035] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.
[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0037] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0040] In the related art, in diagnosis and surgery using an endoscope, it is often necessary to make a preliminary measurement of the lesion location to facilitate the selection of appropriate treatment methods or surgical instruments of appropriate sizes. However, there is currently no specific measuring instrument. The reason is that the disposable instrument itself has a certain cost, the operation of replacing the instrument during the endoscope is cumbersome and there is a risk of contamination. Usually, other necessary instruments are commonly used in clinical practice for rough measurement, such as using a biopsy forceps with an outer diameter of 2.4mm for measurement (using a biopsy forceps with an outer diameter of 2.4mm for measurement, the width of the measured component is about 5 / 0.3 biopsy forceps thick, then its width is about 10-15 / 0.6-0.9mm), but the deviation of this measurement result is relatively large. Based on this, how to improve the accuracy of measurement while saving costs and facilitating operation is a problem that technicians in this field urgently need to solve.
[0041] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a transparent cap, which includes a transparent cap body 100, and the transparent cap body 100 has a front end 110 and an end 120 that are relatively arranged; wherein, the front end 110 is provided with a plurality of preset marking points, and the plurality of preset marking points are arranged at intervals along the circumference of the transparent cap body 100, and the portion of the transparent cap body 100 located at the preset marking points is provided with a marking portion.
[0042] In these embodiments, it should be noted that the transparent cap is almost always used regardless of whether the endoscope is used for diagnosis or surgery. The transparent cap is an accessory fixed to the head end of the endoscope and exposed, and is often used to separate stacked tissues and expand the field of vision. The part exposed by the endoscope can be cylindrical or conical. The cylindrical field of vision is better, and the conical shape is easier to separate tissues. In this application, by adding marks on the transparent cap, the affected area (i.e., the measured tissue) can be easily measured.
[0043] The present application takes the transparent cap as a column as an example. Of course, in other embodiments, the transparent cap may also be a cone, and the same is applicable.
[0044] The transparent cap body 100 has a front end 110 and a rear end 120 , wherein the rear end 120 is used to be fixed on the head end of the endoscope, and the front end is the head of the transparent cap, that is, it passes over the endoscope in the axial direction.
[0045] Exemplarily, the present application takes a plurality of preset marking points including a plurality of first preset marking points 200 as an example. Of course, in other embodiments, a plurality of preset marking points may be separately set to include a plurality of second preset marking points 400; or, a plurality of preset marking points may be separately set to include a plurality of third preset marking points 500. Alternatively, at least two of the three are used in combination. A plurality of first preset marking points 200 are provided at the front end 110 of the transparent cap body 100, and these first preset marking points 200 are arranged at intervals along the circumference of the transparent cap body 100. A first marking portion is provided at the portion of the transparent cap body 100 located at the first preset marking point 200, and these first marking portions are clearly visible in the endoscopic image, thereby facilitating the measurement of the measured tissue.
[0046] Obviously, by adding first marking points on the transparent cap, and since the position of each first marking point is fixed, the distance between adjacent first marking points is also fixed, and the first marking points can be used to intuitively measure the size of the diseased tissue in the endoscopic image.
[0047] That is to say, the transparent cap body 100 is fixed to the head end of the endoscope, and the front end 110 of the transparent cap body 100 partially extends out of the field of view of the endoscope. During endoscopic examination or surgery, by observing the image displayed by the endoscope, the first preset marking point 200 of the front end 110 of the transparent cap body 100 can be seen. When the size of the diseased tissue needs to be measured, the boundary of the measured tissue can be determined according to the first preset marking point 200 on the front end 110 of the transparent cap body 100, and then the size of the measured tissue can be calculated. Of course, by adding the first marking point on the transparent cap, accurate measurement of the diseased tissue can be achieved, avoiding the error caused by using other instruments. And the transparent cap is usually disposable, but adding the first marking point on it does not increase too much cost, but improves its use value. At the same time, there is no need to replace other measuring instruments, and the measurement can be completed directly using the transparent cap, which simplifies the operation process. And the number of times the instrument is replaced is reduced, reducing the risk of cross infection.
[0048] Based on this, it is obvious that the transparent cap provided by the present application can be used in clinical practice. For example, in gastrointestinal endoscopy, the doctor can use a transparent cap with a first marking point to measure the size of polyps or other diseased tissues, so as to decide whether resection is needed and to select the appropriate resection tool. This not only improves the accuracy of the measurement, but also provides a reliable basis for subsequent treatment. In summary, through the above design, the present application provides a simple and effective solution, which not only solves the shortcomings of traditional measurement methods, but also brings higher accuracy and convenience to endoscopic examinations and surgeries.
[0049] like Figure 1 and Figure 2 As shown, in some embodiments, the multiple preset marking points include multiple first preset marking points 200, the portion of the transparent cap body 100 located at the first preset marking points 200 is provided with a first marking portion, the first marking portion includes a first protruding portion, the multiple first preset marking points 200 are located on the end surface of the front end 110, and the multiple first preset marking points 200 are evenly distributed along the circumference of the transparent cap body 100, and the first protruding portion is provided at the first preset marking point 200.
[0050] In these embodiments, the design of the transparent cap is not limited to a simple first preset marking point 200, but further optimizes the structure of the first preset marking point 200 to improve its visibility and measurement accuracy during endoscopic examination. Specifically, the design of the transparent cap body 100 is as follows:
[0051] A plurality of first preset marking points 200 are arranged on the end face of the front end 110 of the transparent cap body 100, and these first preset marking points 200 are evenly distributed along the circumference of the transparent cap body 100. The portion of the transparent cap body 100 located at the first preset marking point 200 is provided with a first marking portion, and the first marking portion includes a first protruding portion. In other words, the first marking portion is arranged at the first preset marking point 200 for easy observation and identification. And by setting the first marking portion as a first protruding portion, i.e., a protruding structure, it is avoided to be blocked. For example, in the present embodiment, the first protruding portion and the transparent cap body 100 are arranged in an integrated manner. Of course, in other embodiments, the first protruding portion can also be connected to the transparent cap body 100 by a fixing method such as bonding.
[0052] Obviously, a plurality of first preset marking points 200 are located on the end surface of the front end 110 and are evenly distributed along the circumference of the transparent cap body 100. The first protrusion is provided at the first preset marking point 200, so that the first preset marking point 200 is more obvious in the endoscope image, which is convenient for observation and measurement.
[0053] Therefore, the setting of the first raised portion makes the marking point more obvious and easy to identify in the endoscopic image, thereby improving the measurement accuracy. The design of the first raised portion makes the first preset marking point 200 more prominent in the endoscopic image, which is convenient for doctors to observe and record.
[0054] Furthermore, since the end face of the front end 110 of the transparent cap body 100 is provided with a first protrusion, during measurement, the front end 110 of the transparent cap body 100 abuts against the measured tissue through the first protrusion, so as to increase the friction between the transparent cap body 100 and the measured tissue, facilitate fixing the relative position between the transparent cap body 100 and the measured tissue, facilitate identification of the first protrusion, and ensure accurate measurement.
[0055] For example, the specific steps are as follows:
[0056] A plurality of first preset marking points 200 are arranged at the front end 110 of the transparent cap, and each of the first preset marking points 200 is provided with a first protrusion;
[0057] Bring the front end 110 of the transparent cap close to the measured tissue, and record the two first preset marking points 200 located at the two ends of the maximum width direction of the measured tissue respectively;
[0058] The distance between the two first preset marking points 200 respectively located at the two ends of the maximum width direction of the measured tissue is calculated to obtain the maximum width dimension of the measured tissue.
[0059] Among them, since the distance between adjacent first preset marking points 200 is set to a preset value, by reading the number of the first preset marking points 200 located between the two ends of the maximum width direction of the measured tissue, the distance between the two first preset marking points 200 located at the two ends of the maximum width direction of the measured tissue is calculated, that is, the maximum width dimension of the measured tissue.
[0060] Of course, the number of first protrusions covered in the measured tissue may also be read and recorded, and since the distance between adjacent first protrusions is known, the maximum width of the measured tissue may be directly obtained.
[0061] For example, in this embodiment, the first protrusion is set to be a triangle. Of course, in other embodiments, the first protrusion can also be set to be a circle, a hemisphere, a square or any other geometric shape that is easy to identify.
[0062] like Figure 2 As shown, in some embodiments, the first protrusion has a tip in a direction away from the front end 110, and the tip is blunted.
[0063] In these embodiments, the design of the transparent cap is not limited to a simple first preset marking point 200, but further optimizes the structure of the first preset marking point 200 to improve its visibility and measurement accuracy during endoscopic examination. In particular, the first raised portion has a tip in the direction away from the front end 110, and the tip is passivated. Specifically, in this embodiment, the tip design of the first raised portion makes the marking point more obvious, which is convenient for identification in the endoscopic image, thereby improving the measurement accuracy. After the tip is passivated, it can reduce damage to the tissue and improve the safety of use.
[0064] For example, the plurality of first preset marking points 200 are evenly distributed along the circumference of the transparent cap body 100, ensuring uniformity and consistency during measurement. In other words, no additional measuring tools are required, and the measurement can be completed directly using the first preset marking points 200 on the transparent cap, simplifying the operation process.
[0065] like Figure 3 and Figure 4 As shown, in some embodiments, the multiple preset marking points include multiple second preset marking points 400, the front end 110 is also provided with multiple second preset marking points 400, the multiple second preset marking points 400 are arranged on the inner wall of the front end 110, the multiple second preset marking points are arranged at intervals along the circumference of the transparent cap body 100, and the inner wall of the front end 110 is also set as the first reference point 300, and the first reference point 300 and the second preset marking point 400 are located on the same circumference or the first reference point 300 and the second preset marking point 400 are located on different circumferences.
[0066] In these embodiments, in addition to the first preset marking point 200, the front end 110 is also provided with a plurality of second preset marking points 400, and a first reference point 300. Specifically, a plurality of first preset marking points 200 are provided at the front end 110 of the transparent cap body 100, and these first preset marking points 200 are evenly distributed along the circumference of the transparent cap body 100, so as to roughly measure the width of the measured tissue.
[0067] A plurality of second preset marking points 400 are also provided at the front end 110, and these second preset marking points 400 are provided on the inner wall of the front end 110. The plurality of second preset marking points 400 are provided at intervals along the circumference of the transparent cap body 100. The inner wall of the front end 110 is also provided with a first reference point 300, and the first reference point 300 and the second preset marking point 400 are located on the same circumference or the first reference point 300 and the second preset marking point 400 are located on different circumferences. Of course, the first reference point 300 can also be formed by rays, as long as it has a marking function.
[0068] By adding the first reference point 300 and the second preset marking point 400 on the transparent cap, the linear size of the diseased tissue can be intuitively measured in the endoscopic image by using the fact that the linear distance between each second preset marking point 400 and the first reference point 300 is known. That is to say, in actual operation, the first reference point 300 and the second preset marking point 400 are located on the same circumference, so that the doctor uses the first reference point 300 as a reference in the endoscopic image and places it at one end of the measured tissue, and by obtaining the position of the second preset marking point 400 located at the other end of the measured tissue, the linear width of the measured tissue can be obtained.
[0069] During gastrointestinal endoscopy, doctors can use a transparent cap with a second preset marking point 400 to measure the size of polyps or other diseased tissues, so as to decide whether resection is necessary and to select the appropriate resection tool. Doctors can determine the boundary of the diseased tissue and place the first reference point 300 at the boundary of the diseased tissue as a reference point, which can provide a fixed positioning reference, and obtain the second preset marking point 400 located on the boundary to help doctors make better measurements. In other words, the combination of the first reference point 300 and the second preset marking point 400 can provide a clearer boundary indication, which is convenient for doctors to make accurate measurements.
[0070] Exemplarily, the second preset marking points 400 are non-uniformly distributed in the circumferential direction of the transparent cap body 100 to control the distance between the second preset marking points 400 and the first reference points 300 to be an integer for ease of use.
[0071] For example, the first reference point 300 can be set as an obvious marking point, such as a large protrusion or depression, so that the doctor can quickly identify it in the endoscopic image. The first reference point 300 should be located on the same circumference as the second preset marking point 400 to ensure that the relative position relationship between them is consistent.
[0072] Exemplarily, the material of the transparent cap body 100 and the second preset marking point 400 should be selected from materials with good biocompatibility, such as medical-grade plastics.
[0073] like Figure 4 As shown, in some embodiments, the distribution positions of the plurality of second preset marking points 400 are symmetrical about the longitudinal cross section of the transparent cap body 100 where the first reference point 300 is located.
[0074] In particular, a plurality of second preset marking points 400 are arranged at intervals along the circumference of the transparent cap body 100, and these second preset marking points 400 are symmetrically distributed about the longitudinal section of the transparent cap body 100 where the first reference point 300 is located. The first reference point 300 and the second preset marking point 400 are located on the same circumference, so that the second preset marking point 400 is more balanced in the endoscopic image, and both sides of the first reference point can be measured without a specific direction, which is convenient for doctors to perform accurate measurements. Among them, the distance between the second preset point and the first reference point directly opposite to the first reference point 300 is the maximum measurement range.
[0075] Exemplarily, the number of second preset marking points 400 is 9, among which the distance between the first second preset marking point 400 and the first reference point 300 is 2 mm, the distance between the second second preset marking point 400 and the first reference point 300 is 4 mm, the distance between the third second preset marking point 400 and the first reference point 300 is 6 mm, the distance between the fourth second preset marking point 400 and the first reference point 300 is 8 mm, the distance between the fifth second preset marking point 400 and the first reference point 300 is 10 mm, the distance between the sixth second preset marking point 400 and the first reference point 300 is 8 mm, the distance between the seventh second preset marking point and the first reference point 300 is 6 mm, the distance between the eighth second preset marking point 400 and the first reference point 300 is 4 mm, and the distance between the ninth second preset marking point 400 and the first reference point 300 is 2 mm. Of course, in other embodiments, the number of the second preset points is 2, 3, 4, 5, 6, 7, 8, etc.
[0076] It should be noted that the distances between adjacent second preset points can be configured so that the distance between the midpoint between the first second preset marking point 400 and the second second preset marking point 400 and the first reference point is 3 mm, the distance between the midpoint between the second second preset marking point 400 and the third second preset marking point 400 and the first reference point is 5 mm, the distance between the midpoint between the third second preset marking point 400 and the fourth second preset marking point 400 and the first reference point is 7 mm, the distance between the midpoint between the fourth second preset marking point 400 and the fifth second preset marking point 400 and the first reference point is 6 mm, and the distance between the midpoint between the fourth second preset marking point 400 and the fifth second preset marking point 400 and the first reference point is 7 mm. The distance between the first reference point is 9mm, so that the distance between the midpoint between the fifth second preset marking point 400 and the sixth second preset marking point 400 and the first reference point is 7mm, the distance between the midpoint between the sixth second preset marking point 400 and the seventh second preset marking point 400 and the first reference point is 5mm, the distance between the midpoint between the seventh second preset marking point 400 and the eighth second preset marking point 400 and the first reference point is 3mm, and the distance between the midpoint between the eighth second preset marking point 400 and the first reference point 300 and the first reference point is 1mm.
[0077] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, in some embodiments, the plurality of preset marking points include a plurality of second preset marking points 400, the front end 110 is further provided with a plurality of second preset marking points 400, the plurality of second preset marking points 400 are provided on the inner wall of the front end 110, the plurality of second preset marking points are provided at intervals along the circumference of the transparent cap body 100, and the inner wall of the front end 110 is further provided with a first reference point 300, and the first reference point 300 and the second preset marking point 400 are located on the same circumference or the first reference point 300 and the second preset marking point 400 are located on different circumferences;
[0078] The plurality of preset marking points include a plurality of third preset marking points 500, the front end 110 is further provided with a plurality of third preset marking points 500, the plurality of third preset marking points 500 are provided on the inner wall of the front end 110, the plurality of third preset marking points are provided at intervals along the circumference of the transparent cap body 100, and the inner wall of the front end 110 is further provided with a second reference point 600, and the second reference point 600 and the third preset marking point 500 are located on the same circumference or the second reference point 600 and the third preset marking point 500 are located on different circumferences;
[0079] Among them, the second preset marking point 400 is set on one side of the front end 110, and the third preset marking point 500 is set on the other side of the front end 110. The distance between the second preset marking point 400 and the first reference point 300 is an even number, and the distance between the third preset marking point 500 and the second reference point 600 is an odd number.
[0080] In these embodiments, in addition to the first preset marking point 200, the front end 110 is also provided with a plurality of second preset marking points 400 and a third preset marking point 500, the distance between the second preset marking point 400 and the first reference point 300 is an even number, and the distance between the third preset marking point 500 and the second reference point 600 is an odd number, and this design allows the doctor to select the marking points on the corresponding side for measurement according to different measurement requirements. For example, when the width of the measured tissue measured by the second preset marking point 400 in cooperation with the first reference point 300 does not meet an even number, in order to improve the measurement accuracy, the measured tissue is measured by the third preset marking point 500 in cooperation with the second reference point 600. Alternatively, when the width of the measured tissue measured by the third preset marking point 500 in cooperation with the second reference point 600 does not meet an odd number, in order to improve the measurement accuracy, the measured tissue is measured by the second preset marking point 400 in cooperation with the first reference point 300. It should be noted that the measurement method of the second preset marking point 400 in conjunction with the first reference point 300 and the measurement method of the third preset marking point 500 in conjunction with the second reference point 600 are the same.
[0081] Furthermore, the second preset marking point 400 and the third preset marking point 500 are respectively located on both sides of the transparent cap body 100 so as to facilitate quick distinction.
[0082] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the second preset marking point 400 is provided with a second marking portion, and the third preset marking point 500 is provided with a third marking portion, and the second marking portion and the third marking portion have different structures.
[0083] In these embodiments, the second marking portion and the third marking portion have different structures, so that the doctor can more easily distinguish different marking points in the endoscopic image. Thereby improving the accuracy and convenience of measurement. For example, the second marking portion can be designed to be different shapes, such as triangle, circle or square, etc., so as to facilitate distinction in the endoscopic image. In addition, the second marking portion can be designed to have different colors to make it more eye-catching in the endoscopic image. Furthermore, the second marking portion can be designed to have different textures or surface treatments to distinguish it from other marking portions.
[0084] For example, the third marking portion can be designed to have different shapes, such as a cross, an oval, or other unique shapes, so as to facilitate distinction in the endoscopic image. In addition, the third marking portion can be designed to have different colors to make it more eye-catching in the endoscopic image. Similarly, the third marking portion can be designed to have different textures or surface treatments to distinguish it from other marking portions.
[0085] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the second marking portion is set as a second protruding portion, and the third marking portion is set as a third protruding portion, and the structures of the second protruding portion and the third protruding portion are different.
[0086] As mentioned above, by providing the third convex portion and the second convex portion, it is easier for doctors to identify and improve the measurement accuracy. The second convex portion and the third convex portion are configured differently to facilitate the doctor to distinguish.
[0087] For example, the second protrusion is configured to be conical, and the third protrusion is configured to be arc-shaped. No specific limitation is given here, as long as the two can be distinguished.
[0088] In some embodiments, the first reference point 300 and the second reference point 600 overlap, and the first reference point 300 is provided with a fourth marking portion, and the structures of the second marking portion, the third marking portion and the fourth marking portion are all different.
[0089] In these embodiments, the first reference point 300 is also the second reference point 600, and the first reference point 300 is provided with a fourth marking portion, and the structures of the second marking portion, the third marking portion and the fourth marking portion are all different, so that the doctor can more easily distinguish different marking points in the endoscopic image, thereby improving the accuracy and convenience of the measurement.
[0090] Furthermore, the first reference point 300 and the second reference point 600 are combined into one, that is, the second preset marking point 400 and the third preset marking point 500 share one reference point, which makes it easier for doctors to identify and operate.
[0091] Exemplarily, the fourth marking portion is configured as a groove portion opened at the front end 110. Of course, in other embodiments, the fourth marking portion may also be configured as a fourth protrusion portion having a shape different from the first protrusion portion, the second protrusion portion, and the third protrusion portion.
[0092] In some embodiments, the present application further provides an endoscope system, which includes an endoscope and a transparent cap as in any of the above embodiments, wherein the transparent cap body 100 has a terminal end 120, and the terminal end 120 is connected to the head end of the endoscope.
[0093] Generally, the transparent cap body 100 has a front end 110 and a rear end 120 that are arranged opposite to each other. The front end 110 of the transparent cap body 100 is used to push aside the intestinal mucosa, so that the intestinal mucosa and the lens are separated by a certain distance. The rear end 120 of the transparent cap body 100 is plug-in connected to the head end of the endoscope.
[0094] In addition, since the above-mentioned transparent cap has the above-mentioned technical effects, the endoscope system including the transparent cap should have the same technical effects, which will not be repeated here.
