Description

Technical Field

[0001] This utility model relates to the field of endoscopic snake bone testing, and in particular to an endoscopic snake bone bending fatigue testing device. Background Technology

[0002] The endoscopic stylus is a crucial component of an endoscope, primarily used to control the bending of the endoscope's tip, allowing for flexible observation of different areas during examinations. Composed of multiple segments, similar to a snake's spine, the stylus is highly flexible. It is typically made of stainless steel or nickel-titanium alloy, balancing strength and flexibility. The stylus is controlled by an operating handle, facilitating the endoscope's maneuverability within the body. This helps doctors accurately locate and observe target areas, improving examination accuracy. Endoscopic styluses are widely used in gastroscopy, colonoscopy, and bronchoscopy for examining the digestive and respiratory tracts. They are also sometimes applied in industrial settings, primarily for pipeline inspection and equipment maintenance, examining complex or confined spaces.

[0003] In the medical field, especially for endoscopes used for internal human examinations, fatigue damage to the stylus can cause the endoscope to malfunction and even harm the patient. In industrial inspection, it can also affect the accuracy of test results and the normal operation of equipment. Endoscopes are frequently manipulated in medical and industrial inspection scenarios, causing the stylus to bend continuously. Fatigue testing simulates this repeated bending motion to verify whether the stylus can withstand a specified number of cycles without failure.

[0004] Traditional fatigue testing is usually done manually, which has the disadvantages of low repeatability, poor accuracy, high manpower consumption and low efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies where fatigue testing is typically done manually, resulting in low repeatability, poor accuracy, high manpower consumption, and low efficiency, this invention provides an endoscopic snake skeleton bending fatigue testing device. The endoscopic snake skeleton includes a body and multiple steel wires, with the body connected to the multiple steel wires.

[0006] The support platform is equipped with a fixed seat and a traction assembly. The fixed seat is used to fix the body of the snake bone. The traction assembly includes a motor and a traction wheel. The motor and the traction wheel are connected by a drive, and the traction wheel is connected to the steel wire of the snake bone.

[0007] The first test module includes a first photoelectric sensor and a second photoelectric sensor, which are respectively mounted on both sides of the fixed base.

[0008] The second test module includes a first wire, a PCB board, and a second wire. The first wire and the second wire are respectively connected to the PCB board. The first wire is also connected to the snake body, and the second wire is also connected to the steel wire.

[0009] Optionally, a guide wheel is provided on the support platform, located between the direct fixing seat and the traction component, and the steel wire of the snake bone contacts the guide wheel.

[0010] Optionally, the bottom adjustment seat of the guide wheel has a mounting groove on the support platform, the adjustment seat is installed in the mounting groove, the adjustment seat has an elongated hole, and the support platform has a screw hole, the position of the screw hole corresponds to the position of the elongated hole.

[0011] Optionally, the mounting base includes a base and a connecting block, the connecting block being mounted on the base and connected to the snake bone body.

[0012] Optionally, the base has a groove, and multiple through holes are provided on both sides of the groove, and the connecting block has through holes.

[0013] Optionally, mounting components are provided on both sides of the support platform, with the first photoelectric sensor mounted on the mounting component on one side and the second photoelectric sensor mounted on the mounting component on the other side.

[0014] Optionally, the mounting assembly includes a base plate and a mounting plate. The base plate is connected to a support platform. The first photoelectric sensor or the second photoelectric sensor is mounted on the mounting plate. The base plate has multiple through holes, and the mounting plate has elongated holes. The mounting plate is fixed to the base plate with bolts.

[0015] Optionally, a chassis is also included, with a support platform mounted on top of the chassis.

[0016] Optionally, a controller is installed inside the chassis, which is electrically connected to the PCB board, the first photoelectric sensor, the second photoelectric sensor, and the traction component.

[0017] Optionally, a display is provided on the chassis, and the display is electrically connected to the controller.

[0018] The beneficial effects of this utility model are as follows: The motor drives the traction wheel to rotate, the traction wheel pulls the steel wire, the steel wire causes the snake bone to bend, and the traction wheel rotates repeatedly in different rotation directions, causing the snake bone to bend repeatedly at a predetermined force. The first photoelectric sensor and the second photoelectric sensor are used to sense the positional changes of the snake bone bending and record and provide feedback on the bending of the snake bone body. At this time, if the snake bone is damaged and the snake bone body cannot reach the predetermined degree of bending, the first photoelectric sensor or the second photoelectric sensor will promptly report the abnormal positional change of the snake bone body, thereby terminating the test. The first wire and the second wire are respectively connected to the body and the steel wire, and the first wire and the second wire... Two wires are connected to the PCB board respectively. Since both the snake-like body and the steel wire are made of metal and are conductive, the first and second wires form a circuit path between the body and the steel wire. If the steel wire breaks, the circuit becomes open, and it is no longer a circuit. The PCB board then feeds back the circuit change signal. The change in the continuity of the circuit determines whether the steel wire is broken, and thus determines whether to terminate the test. The first test module records the number of bends and determines whether to terminate the test by changing the bending position of the body. The second test module determines whether to terminate the test by checking whether the steel wire is broken. The first and second test modules work together to detect the overall test status of the snake-like body. Attached Figure Description

The fixing seat 201 is used to fix the body 101 of the snake skeleton; the traction assembly 202 includes a motor 203 and a traction wheel 204, which are connected to each other.

The second test module includes a first wire 401, a PCB board 402, and a second wire 403. The first wire 401 and the second wire 403 are respectively connected to the PCB board 402. The first wire 401 is also connected to the snake body 101, and the second wire 403 is also connected to the steel wire 102.

[0028] During implementation, a fixed base 201 and a traction assembly 202 are installed on the support platform 2. The snake bone body 101 is fixed on the fixed base 201. The motor 203 and traction wheel 204 of the traction assembly 202 are connected for transmission. The steel wire 102 on the snake bone is connected to the traction wheel 204. A first photoelectric sensor 301 and a second photoelectric sensor 302 are installed on both sides of the fixed base 201, respectively. The first wire 401 of the second test module is connected to the snake bone body 101, and the second wire 403 is connected to the steel wire 102. The first wire 401 and the second wire 403 are respectively connected to the PCB board 402; the motor 203 drives the traction wheel 204 to rotate, the traction wheel 204 pulls the steel wire 102, the steel wire 102 causes the snake bone to bend, and the traction wheel 204 rotates repeatedly in different rotation directions, causing the snake bone to bend repeatedly at a predetermined force. The first photoelectric sensor 301 and the second photoelectric sensor 302 are used to sense the positional change of the snake bone bending and record and provide feedback on the bending of the snake bone body 101. At this time, if the snake bone is damaged, the snake bone body 101 cannot reach the desired position. When the predetermined bending degree is reached, the first photoelectric sensor 301 or the second photoelectric sensor 302 will promptly report any abnormal positional change in the snake-like body 101, thereby terminating the test.

If the steel wire 102 breaks, the circuit becomes open, and it is no longer a circuit. The PCB board 402 then feeds back the circuit change signal. The change in the continuity of the circuit is used to determine whether the steel wire 102 is broken, thereby determining whether to terminate the test. The first test module records the number of bends and determines whether to terminate the test by measuring the bending position change of the body 101. The second test module determines whether to terminate the test by measuring whether the steel wire 102 is broken. The first test module and the second test module work together to detect the overall test status of the snake-like body.

The PCB board 402 has a connection circuit, and the first wire 401 and the second wire 403 are connected through the connection circuit.
