Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a device for detecting the flexibility of an endoscope hose. Background Art

[0002] The insertion part of the flexible endoscope can be bent and deformed, so that the working channel inside the insertion part can be bent together. The working channel is a plastic hose structure. Because the insertion part of the endoscope needs to be bent repeatedly during normal operation, the working channel inside it is bent. If the flexibility of the working channel is poor, it is easy to cause the working channel to bend and damage during the use of the endoscope, resulting in creases on the working channel, and it cannot be completely restored to its original shape, which makes it impossible to insert instruments or transport liquids from the working channel during use.

[0003] Therefore, in the production process of endoscopes, it is necessary to test the flexibility of the working channel hose to determine whether it meets the requirements. In the prior art, the flexibility test of the working channel hose is to print circles of different diameters on paper, and then bend the hose according to the circles to determine its flexibility. Because this method is different from the actual use environment of the hose, it cannot truly reflect the flexibility of the product when it is used, and the detection efficiency is not high.

[0032] The utility model provides an endoscope hose flexibility detection device 100, which can be used to detect the flexibility of a hose 200 forming a working channel in an endoscope to ensure that the hose 200 can meet the bending requirements of a corresponding type of endoscope.

[0033] See also Figure 1 to Figure 2 In this embodiment, the endoscope hose flexibility detection device 100 includes a detection body 1 and a detection member 2; the detection member 2 is arranged on the detection body 1, and a detection channel is formed on the detection member 2, the detection channel is arranged in an arc shape, and the extension path of the detection channel is bent along the same plane.

[0034] In this embodiment, the detection body 1 can be suitable for being fixed on a detection platform or other structures; the detection member 2 is arranged on the detection body 1, and a detection channel is formed on the detection member 2. The detection channel is arranged in an arc shape, so that the hose 200 can bend along with the bending of the detection channel when it is accommodated in the detection channel; and the bending path of the detection channel is on the same plane. When the hose 200 is accommodated in the detection channel, the detection channel can provide a certain abutting force on the hose 200, which is more in line with the actual working relationship between the hose 200 and the insertion part in the actual use environment of the insertion part of the endoscope. Therefore, the flexibility of the hose 200 can be better detected, the detection result is more accurate and reliable, and the detection efficiency is also higher.

[0035] The shape of the detection body 1 is not specifically limited. Preferably, the detection body 1 is substantially cylindrical so as to be suitable for the hose 200 to be wound around.

[0036] It can be understood that the detection member 2 can be detachably connected to the detection body 1. Alternatively, the detection member 2 can be integrally formed with the detection body 1, and the detection member 2 is formed as a part of the detection body 1.

[0037] Specifically, when the detection member 2 and the detection body 1 are integrally arranged.

[0038] In one embodiment, in combination Figures 1 to 3 As shown, the detection member 2 may include a first detection groove 21 disposed on the outer peripheral side of the detection body 1, the notch of the first detection groove 21 is disposed outward, and the groove cavity thereof forms the detection channel. The specific detection method is: the hose 200 can be wound in the first detection groove 21 from the notch of the first detection groove 21. Since the hose 200 is generally made of plastic, if the hose fails after bending, creases will appear, which will affect the complete recovery of the hose 200. Therefore, after the hose 200 is wound in the first detection groove 21, the condition of the hose 200 can be observed. If the hose 200 does not have bending creases, it means that the hose 200 meets the standards and meets the requirements; if the hose 200 has creases after bending in the first detection groove 21, it means that the hose 200 does not meet the standards and does not meet the standards.

[0039] Among them, the inside and outside in the utility model are relative to the detection body 1 itself, the center of the detection body 1 in its radial direction is the inside, and the side away from the center to form the appearance surface is the outside. Therefore, the notch of the first detection groove 21 extends along the circumference of the detection body 1 and is set away from the center of the detection body 1. The groove bottom of the first detection groove 21 is the side opposite to the notch, and the groove depth is the distance between the notch and the groove bottom. Preferably, the groove depth is greater than or equal to half the diameter of the hose 200, so that the hose 200 can be better accommodated in the first detection groove 21.

[0040] In another embodiment, Figure 4As shown in , when the detection body 1 is arranged in a circular ring shape, the detection member 2 may include a second detection groove 22 arranged on the inner side wall of the detection body 1, the notch of the second detection groove 22 is arranged inward, and its groove cavity forms the detection channel, and an opening is arranged on one side of the second detection groove 22, and the opening is suitable for the hose 200 to pass from the outside of the detection body 1 into the second detection groove 22, so as to facilitate the hose 200 to be wound from the outside of the detection body 1 into the second detection groove 22, and the second detection groove 22 is used to form a bending channel of the hose 200, so as to detect the flexibility of the soft. The specific detection method can refer to the above, after the hose 200 is wound in the second detection groove 22, observe the condition of the hose 200, if the hose 200 has no bending crease, it means that the hose 200 meets the standard and meets the requirements; if the hose 200 has creases after bending in the second detection groove 22, it means that the hose 200 does not meet the standard.

[0041] In another embodiment, the detection channel can be configured as an annular through hole on the detection body, the annular channel is extended around the circumference of the detection channel, and the hose 200 is passed through the annular channel to detect the hose 200 .

[0042] When the detection member 2 and the detection body 1 are detachably connected.

[0043] A first limiting groove may be provided on the detection body 1, and a second limiting groove may be provided on the detection member 2. The notch of the first limiting groove and the notch of the second limiting groove are opposite to each other, and the first limiting groove and the second limiting groove together form the detection channel. The first limiting groove and the second limiting groove are respectively limited to the two sides of the hose 200, so that the hose 200 is more adapted to the curved shape of the detection channel when bending, so that the detection accuracy is better. The specific detection method is also similar to the above. The hose 200 can be firstly wound in the first limiting groove or the second limiting groove, and then the detection member 2 and the detection body 1 are connected and fixed, so that the hose 200 can be kept in the bent state for a longer time, so that the detection result can be more accurate.

[0044] Of course, when the detection member 2 is disposed on the outer peripheral side of the detection body 1 , the hose 200 can be better exposed, so that it is more convenient for the detection personnel to observe the hose 200 .

[0045] There may be a plurality of detection members 2, so that one endoscope hose flexibility detection device 100 can detect a plurality of hoses 200 at the same time, thereby improving detection efficiency.

[0046] In addition, since there are many types of endoscopes, such as ureteroscopes, bronchoscopes, choledochoscopes, etc., the diameters of the insertion parts of different types of endoscopes are different, so the diameters of the corresponding hoses 200 are also different. Therefore, when there are multiple detection members 2, the diameters of the detection channels on the multiple detection members 2 can be set differently, so that the hoses 200 on different types of endoscopes can be detected, so that the detection range of the endoscope hose flexibility detection device 100 is wider.

[0047] Preferably, if Figure 3 As shown in the figure, along the axial direction of the detection body 1, the diameters of the plurality of detection channels are arranged in increasing or decreasing order, and a mark may be provided on each detection member 2. Different detection members 2 may correspond to the detection of different endoscope hoses 200, so that the detector can perform matching more quickly and the detection efficiency is higher.

[0048] In one embodiment, each of the detection members 2 can be configured as a detection cylinder, each detection cylinder is sleeved on the outer ring side of the detection body 1, and the detection channel is disposed on the outer ring side of the detection cylinder; or Figure 4 As shown in , each detection cylinder is sleeved on the inner ring side of the detection body 1, and the detection channel is arranged on the inner ring side of the detection cylinder. Each detection cylinder and the detection body 1 can be quickly disassembled and assembled, so different types of detection cylinders can be installed on the detection body 1, so that the detection range of the endoscope hose flexibility detection device 100 is larger.

[0049] Furthermore, the detection channel can be arranged in a full circle, so that the hose 200 can be arranged in a full circle in the detection channel, so as to better detect the flexibility of the hose 200 at various bending angles. Alternatively, the detection channel is arranged in a non-closed ring, for example, the detection channel is a semicircle, or a quarter circle arc segment, or a three-quarter circle arc segment, etc., so that the detection of the hose 200 can be more consistent with its actual use conditions.

[0050] Furthermore, the diameter of the detection channel is suitable to be equivalent to the bending diameter of the insertion part of the endoscope, or the diameter of the detection channel is slightly smaller than the bending diameter of the insertion part of the endoscope, so that the detection conditions of the hose 200 are more stringent than the actual use conditions, thereby making the flexibility of the hose 200 better and better meeting the use requirements of the endoscope.

[0051] It can be understood that the implementation methods of the endoscope hose flexibility detection device 100 include but are not limited to the above, and the configuration method of the endoscope hose flexibility detection device 100 can also be a combination of two or more of the above-mentioned implementation methods. When the detection conditions of the hose 100 are better met, reasonable adaptive adjustments can be made.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the specification and drawings of the present invention, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
