Description

Technical Field

[0001] This utility model relates to the field of endoscopy, and more specifically, to an endoscope snake-bone bending test fixture. Background Technology

[0002] An endoscope works by inserting a tube into a body cavity. The end of the tube is equipped with a light source and a camera assembly. The camera assembly connects to an external image processor and monitor to observe lesions within the body cavity. The direction of the tube's movement is controlled by a serpentine skeleton; adjusting the skeleton's bending angle controls its direction. Specifically, the skeleton has internal steel wires; pulling these wires controls the skeleton's bending angle.

[0003] Currently, controlling the bending angle of the skeletal skeleton by pulling the steel wire mainly relies on the experience and feel of technicians. The operation is highly subjective, and it is impossible to accurately compare the bending deformation angle of the skeletal skeleton with the tension of the steel wire. In actual use, it may not be possible to control it accurately, which can easily lead to operational errors and affect the reliability of endoscopic observation. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] As described in the background section, the bending and deformation angle of the endoscopic serpentine is mainly achieved by manipulating the steel wire. However, manipulating the steel wire relies heavily on the technician's feel and experience, which makes the operation highly subjective and unfriendly to novices. Furthermore, it is difficult to guarantee the consistency and accuracy of operation for different technicians. In particular, when the insertion depth of the serpentine is large, relying on experience and feel is not only unreliable but also prone to errors, thus affecting the normal observation and use of the endoscope.

[0037] Based on the above problems, this utility model provides an endoscopic snake bone bending test fixture. This test fixture establishes a one-to-one correspondence between the snake bone bending angle and the wire tension by testing the wire tension at different bending angles of the snake bone. This solves the problem that existing methods relying on the operating experience of technicians are unreliable. The endoscopic snake bone bending test fixture will be described in detail below.

[0038] Please refer to Figures 1 to 3The endoscopic snake bone bending test fixture includes: a base 1, a guide rail 2, a slider 21, and a tension detector 22. The guide rail 2 is set on the base 1, the slider 21 is fitted onto the guide rail 2 and slides with the guide rail 2, and the tension detector 22 is set on the slider 21. The tension detector 22 is connected to one end of a steel wire 6, and the other end of the steel wire 6 is connected to the snake bone 5. When the slider 21 slides on the guide rail 2, it drives the tension detector 22 to move, and the steel wire 6 connected to the tension detector 22 is also driven to move. The steel wire 6 drags the snake bone 5 at the other end, causing the snake bone 5 to bend and deform. At this time, the bending deformation angle of the snake bone 5 corresponding to the tension value on the tension detector 22 can be viewed, and this correspondence can be recorded. By testing the bending deformation angle of the snake bone 5 corresponding to different tension values ​​multiple times, a rich correspondence can be obtained. These correspondences can be used to guide the endoscope user. Even if the user does not have sufficient experience, they can operate the endoscope accurately and reliably. Moreover, the correspondences are accurate and misjudgment is not easy, thereby greatly improving the normal observation effect of the endoscope.

[0039] Specifically, the base 1 is block-shaped and has a flat surface. Multiple guide rails 2 are arranged on this surface, and the multiple guide rails 2 are independently set and parallel to each other. The slider 21 is locked onto the guide rails 2 and slides with them. A tension detector 22 is fixedly installed on the top of the slider 21, and the tension detector 22 is connected to the steel wire 6. There are at least two tension detectors 22, and two or more tension detectors 22 are independently set. Each tension detector 22 is individually connected to a steel wire 6, and the end of each steel wire 6 is connected to the snake bone 5. When the ends of multiple steel wires 6 are connected to different parts of the snake bone 5, pulling different steel wires 6 can control the snake bone 5 to bend and deform at different angles.

[0040] The number of sliders 21 is at least two, and the number of sliders 21 is the same as the number of tension detectors 22. One tension detector 22 is fixed on one slider 21. In this embodiment, there are two tension detectors 22 and two sliders 21. There are four guide rails 2, which are arranged in parallel with intervals. One slider 21 is slidably fitted on two guide rails 2, and the other slider 21 is fitted on the other two guide rails 2.

[0041] The slider 21 is connected to a driving component, and the slider 21 is driven to slide through the driving component.

[0042] The driving components include various types, which can be divided into manual and non-manual types. The manual type is operated manually, while the non-manual type is driven by pneumatic, electric or hydraulic devices. The embodiments of this utility model are illustrated by the manual type.

[0043] refer to Figure 2The driving components are a lead screw 3 and a handwheel 31. A threaded hole is provided on the slider 21, and one end of the lead screw 3 passes through the threaded hole and is threadedly connected to the slider 21. A handwheel fixing block 32 is also installed on the base 1. The handwheel fixing block 32 is provided with a threaded hole, and the other end of the lead screw 3 passes through the threaded hole on the handwheel fixing block 32 and is connected to the handwheel 31. The lead screw 3 and the handwheel fixing block 32 only rotate and do not move axially. When the lead screw 3 rotates, the slider 21 and the lead screw 3 rotate relative to each other, so that the lead screw 3 drags the slider 21 to move on the guide rail 2.

[0044] Of course, the lead screw 3 and the slider 21 can also be fixed together. The lead screw 3 and the handwheel fixing block 32 can rotate relative to each other and move axially. In use, the handwheel 31 is turned manually to drive the lead screw 3 to rotate. The lead screw 3 moves towards the handwheel fixing block 32, dragging the slider 21 to move, which in turn drives the steel wire 6 connected to the tension detector 22 to move. It can be seen that the handwheel fixing block 32 is at the end of the guide rail 2, and the lead screw 3 is parallel to the guide rail 2.

[0045] In addition to quantifying the bending angle of the snake bone 5 by measuring the tension value of the tension detector 22, the bending angle of the snake bone 5 can also be determined by measuring the movement distance of the slider 21. Specifically, a scale is set on the base 1, with the scale distributed on the side of the guide rail 2 and extending along the length of the guide rail 2. During the test, the distance the slider 21 moves corresponds to the bending angle of the snake bone 5.

[0046] To facilitate the user in determining the tension of the steel wire 6 by the number of rotations of the handwheel 31, an angle scale is provided on the handwheel 31, and a pointer is provided on the handwheel fixing block 32. The pointer matches the angle scale and remains stationary. For example, when the handwheel 31 is rotated half a turn, the corresponding angle scale is exactly aligned with the pointer, thereby precisely controlling the tension of the steel wire 6 in conjunction with the tension detector 22, and thus precisely controlling the deformation and bending angle and orientation of the snake bone 5.

[0047] To facilitate the connection between the tension detector 22 and the steel wire 6, the tension detector 22 is provided with an adapter shaft 24. One end of the steel wire 6 is connected to the adapter shaft 24, and the other end of the steel wire 6 is connected to the snake bone 5. The adapter shaft 24 is connected to the tension detector 22. For example, the adapter shaft 24 is a hollow tube with internal threads on its inner wall. The tension detector 22 includes a connecting part corresponding to the internal threads, and the tension detector 22 is threadedly connected to the adapter shaft 24.

[0048] The adapter shaft 24 is equipped with a latch, which is used to lock or unlock the steel wire 6. The latch can be a screw that applies radial pressure to the steel wire 6, or a winding post that winds and fixes the steel wire 6 to the winding post; or the latch can be in other forms.

[0049] In this embodiment, the tension detector 22 is communicatively connected to a detection panel 23, which displays the tension value of the tension detector 22. The detection panel 23 can be an LCD screen and is connected to the tension detector 22 via a data transmission line. The tension detector 22 can be a tension sensor; in other embodiments, the tension detector 22 can also be other detection devices.

[0050] Continue to refer to Figure 2 The base 1 is also provided with a wire fixing frame 4. The wire fixing frame 4 includes a fixed base 41 and a guide tube 42. The fixed base 41 is fixed on the base 1. The guide tube 42 is a hollow tube and is set on the fixed base 41. The axial direction of the guide tube 42 is parallel to the guide rail 2 and the lead screw 3. The wire 6 passes through the guide tube 42. The wire fixing frame 4 is used to limit the spatial position of the wire 6 and prevent the wire 6 from moving in any direction other than the axial direction.

[0051] When the snake bone 5 needs to be inserted into a deeper body cavity, the end of the snake bone 5 is connected to an insertion tube 51, the end of the insertion tube 51 is connected to a connecting sleeve 52, the connecting sleeve 52 is fixed to the threaded tube 53, the steel wire 6 is placed inside the threaded tube 53, and the threaded tube 53 passes through the guide tube 42.

[0052] It is worth mentioning that the bending angle of the snake bone 5 can be in any direction, and the specific direction needs to be achieved by setting the corresponding steel wire 6. In this embodiment, only two steel wires 6 are set as an example. In other embodiments, multiple steel wires 6 can be set for testing. When the steel wires 6 are in different spatial positions of the snake bone 5, the height and position of the slider 21 also correspond accordingly to ensure that all steel wires 6 are always parallel, and the direction of the tension detected by the tension detector 22 is along the axial direction of the steel wire 6.

[0053] The endoscopic snake bone bending test fixture of this utility model, through the cooperation of components such as guide rail 2, slider 21 and tension detector 22, can accurately test the relationship between the bending angle of snake bone 5 and the tension of steel wire 6, providing an accurate and reliable basis for actual operation. Compared with the original operation that relies on the experience and feel of technicians, the control accuracy is high and the reliability is good. All operators can complete the operation, avoiding defects such as operational errors caused by human perception factors.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
