Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a disposable ureteroscope snake bone subassembly of sectional type.
Background
Endoscopes generally refer to medical instruments that enter a human body through various ducts to observe the internal conditions of the human body. Since a lesion which cannot be displayed by X-ray can be seen by an endoscope, it is very useful for a doctor. For example, an endoscopist can observe ulcers or tumors in the stomach, and an optimal treatment plan is made according to the observations. Some endoscopes can also be used for therapeutic purposes, such as urology scopes, bronchoscopes, gastroscopes, colonoscopes, and laparoscopes.
A snake bone pipe is arranged in an endoscope body of an existing endoscope, and the head of the endoscope can be bent and turned by drawing a steel wire rope connected with the snake bone pipe. The snake bone pipe adopts a steel wire rope to pull the endoscope body of the endoscope to bend and change direction. However, when the spring tube is welded, the spring tube is welded on the inner wall surface of the tail of the snake bone tube, the position of the spring tube is not accurate during welding due to the narrow space in the snake bone tube, time and labor are wasted during welding, the rejection rate is high, and when the flexible pipe is used, due to the deviation of the position of the spring tube, the deviation occurs when the traction rope pulls the snake bone tube, the snake bone tube cannot reach the required bending angle frequently, and the endoscope is influenced to use.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: in order to overcome the not enough among the prior art, the utility model provides a sectional type disposable ureteroscope snake bone subassembly.
The utility model provides a technical scheme that its technical problem will adopt is: the utility model provides a disposable ureteroscope snake bone subassembly of sectional type, includes snake bone pipe, spring pipe and haulage rope, seted up the multiunit on the snake bone pipe lateral wall and turned to the incision, with organizing turn to the incision and distribute along snake bone pipe axial, turn to crisscross the setting on snake bone pipe lateral wall in different groups, set up a plurality of U-shaped spacing grooves along snake bone pipe axial setting on the snake bone pipe afterbody lateral wall, the spring pipe penetrates from snake bone pipe afterbody, spring pipe tip part supports and locates on the U-shaped spacing groove diapire, the spring pipe lateral wall supports and locates on the U-shaped spacing groove lateral wall, the spring pipe external diameter is greater than the spacing groove width, spring pipe and U-shaped spacing groove welded connection, be equipped with many rope channels of crossing that supply the haulage rope to run through in the snake bone pipe body, the haulage rope passes the spring pipe with cross the rope channel with snake bone pipe front end fixed connection.
When the spring tube is welded, the end face of the spring tube is abutted against the bottom wall of the U-shaped limiting groove, so that the spring tube can be accurately positioned, the machining efficiency is improved, and the rejection rate is reduced; the spring pipe can be embedded into the U-shaped limiting groove, so that the weldable space is increased, and the welding strength is also improved. The steering cut on the side wall of the snake bone pipe can be directly formed by laser cutting on precise laser cutting equipment through the hollow pipe, and the processing efficiency is high. The haulage rope passes the spring pipe and crosses behind the rope passageway and with snake bone pipe front end welded connection, because the spring pipe position is accurate to ensure that the haulage rope position is accurate, through twitching a haulage rope, make a set of incision that turns to shrink, a set of incision that turns to opens, thereby make the snake bone pipe reach suitable bending angle. The spring tube and the rope passing channel are mainly used for protecting the traction ropes and preventing the traction ropes from being clamped or entangled with each other.
Furthermore, in order to ensure that the traction rope cannot be blocked by the bottom wall of the U-shaped limiting groove when penetrating into the snake bone tube from the spring tube, the thickness of the overlapping part of the end part of the spring tube and the bottom wall of the U-shaped limiting groove is smaller than the thickness of the side wall of the spring tube.
Furthermore, the rope passing channel comprises a plurality of rope passing holes, and the rope passing holes are formed by punching the side wall of the snake bone pipe towards the inner side direction of the snake bone pipe. Pass whole snake bone with the haulage rope, through crossing the mobilizable scope of rope hole restriction haulage rope, disturb other parts in the snake bone when preventing the haulage rope to use.
Furthermore, the distance between two adjacent steering incisions in the same group of steering incisions is gradually increased from the front end of the snake bone pipe to the tail end of the snake bone pipe. The requirements of different steering and bending amplitudes of the pipe body at different positions are met.
Furthermore, flaring parts are arranged at two ends of the turning notch. The amount of deformation of the steering cut can be increased and stress concentration can be reduced.
The utility model has the advantages that: the utility model provides a sectional type disposable ureteroscope snake bone component, when adopting the welding assembly of the spring tube, the end surface of the spring tube is close to the bottom wall of the U-shaped limiting groove, thus being capable of accurately positioning, improving the processing efficiency and reducing the rejection rate; the spring tube can be embedded into the U-shaped limiting groove, the welding space is increased, the welding strength is also improved, and the position of the spring tube is accurate, so that the position of the traction rope is accurate, and the snake bone tube can reach a proper bending angle by pulling the traction rope.
