Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a micro-vibration flexible ureteroscope sheath for preventing blockage. Background Technology
[0002] During laser lithotripsy, the resulting stone fragments vary in size and shape. When it is necessary to remove these fragments from the guide sheath, they can easily become lodged within the sheath. Traditional methods involve using the tip of a flexible ureteroscope to push away the obstructing fragments, or re-lightning the sheath with the laser. However, these methods are prone to damage to the ureteroscope, fiber optic cable, or the sheath itself. Furthermore, the procedures are cumbersome, inefficient, prolong the surgery time, and increase the risks.
[0003] Therefore, in order to solve the above problems, the present invention proposes a micro-vibration flexible ureteroscope sheath to prevent blockage. Summary of the Invention
[0004] The present invention aims to provide a micro-vibration flexible ureteroscope sheath to prevent blockage, thereby solving the problem of low surgical efficiency caused by stone fragment blockage.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A micro-vibration ureteroscope sheath for preventing blockage includes a sheath body and a steel wire. The sheath body has a flexible endoscope channel for the flexible endoscope to pass through. The sheath body is divided into a main body and a fixing part. Both ends of the steel wire are located on the outside of the sheath body. The two ends of the steel wire are used to connect with an external power source to form an alternating current circuit. The fixing part has a steel wire channel and a magnet. The steel wire passes through the steel wire channel, and the magnet is located on both sides of the steel wire channel. The two sides of the main body are filled with several sets of magnetic particles.
[0007] Furthermore, the bottom end of the steel wire is divided into a spiral structure, and an insulating tube is installed in the flexible lens channel. The steel wire passes through the insulating tube, which is used to prevent short circuits between the steel wires.
[0008] Furthermore, the magnet has an arc-shaped structure.
[0009] Furthermore, the external power source generates alternating current through the inverter.
[0010] Furthermore, the outer side of the fixing part is provided with anti-slip texture.
[0011] Furthermore, a protective mucosa is provided on the outer side of the soft endoscope sheath.
[0012] The principle and beneficial effects of this technical solution: This invention connects the internal steel wire, originally used for support, to an external alternating circuit, and sets a magnetic field inside the soft endoscope sheath. This allows the steel wire to both provide support and vibrate in a conductive state. The vibrating steel wire can then transmit the vibration to the stuck stone fragments, causing the stone fragments to change direction and no longer block the blockage. The stone fragments can then be removed more easily, effectively solving the problem of stuck stone fragments, improving the efficiency of the surgical procedure, and reducing the risks of the surgical procedure.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0019] like Figures 1-4The illustrated anti-blockage micro-vibration ureteroscopic sheath includes a flexible sheath body 1 and a steel wire 2. The outer wall of the flexible sheath body 1 is covered with a protective mucosa 11 to reduce external vibration. The flexible sheath body 1 includes a main body portion 4 and a fixing portion 5. The lower section of the flexible sheath body 1 is a flexible tube that needs to be inserted into the patient's body, facilitating directional changes. An endoscope channel 3 is provided inside the flexible sheath body 1, through which stone fragments can be removed. The steel wire 2 primarily serves a supporting function, preventing external pressure from blocking the endoscope channel 3. The outer surface of the fixing portion 5 has anti-slip textures. The steel wire 2 passes through the steel wire channel 51 of the fixing portion 5 and then through the steel wire channel 51 into the endoscope channel 3. Both sides of the flexible mirror sheath 1 are provided with arc-shaped magnetic blocks 52. The steel wire 2 is folded back at the bottom end of the flexible mirror sheath 1. The lower end of the steel wire 2 is divided into a spiral structure. The spiral structure can effectively improve the support effect. An insulating pipe 31 is provided in the flexible mirror channel 3 of the spiral structure. The insulating pipe 31 is fixedly connected to the inner wall of the main body 4. The folded steel wire 2 passes through the insulating pipe 31. The insulating pipe 31 can prevent the folded steel wire 2 from contacting the spiral steel wire 2, thereby preventing the lower half of the steel wire 2 from having no current. The two ends of the steel wire 2 are inserted to the outside of the flexible mirror sheath 1. The two ends of the steel wire 2 are used to connect with the external power supply 6 to form an alternating current circuit 7. The external power supply 6 generates alternating current through an inverter. At the same time, both sides of the main body 4 are filled with embedded magnetic particles 41.
[0020] The specific implementation process is as follows: When the stone fragment is stuck inside the flexible endoscope channel 3, the external power supply 6 can be turned on. The external power supply 6 generates alternating current through the inverter. Because the steel wire 2 is conductive, the alternating current will pass through the steel wire 2. At this time, magnet blocks 52 are set on both sides of the steel wire in the fixing part 5. The magnet blocks 52 on both sides form a magnetic field. Several magnetic particles 41 are filled and embedded in the interior of both sides of the main body part 4. The magnetic particles 41 on both sides will also form a magnetic field together. The current-carrying conductor will be subjected to force in the magnetic field. At this time, the current loop is an alternating current. Therefore, the steel wire 2 will be subjected to the forces on both sides alternately under the action of the Lorentz force, thereby generating vibration. The vibration of the steel wire 2 can change the direction of the stuck stone fragment. Therefore, the stone fragment can be better sucked out and removed, effectively improving the efficiency of stone removal.
[0021] The above descriptions are merely embodiments of the present invention, and common technical solutions or characteristics known in the schemes are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
