Description

Technical Field

[0001] This utility model belongs to the field of net processing technology, specifically relating to a peephole retrieval net and its forming and processing equipment. Background Technology

[0002] The mesh basket of a stone retrieval basket is typically made of nickel-titanium alloy wire or 304 stainless steel wire. Nickel-titanium alloy has good shape memory and elasticity, allowing for flexible manipulation under endoscopy, while 304 stainless steel is widely used due to its corrosion resistance and strength.

[0003] Existing nets are usually made of two nickel-titanium alloy wires or 304 stainless steel wires fixed together end to end. The middle part is prone to displacement during movement, resulting in low accuracy in picking up objects. At the same time, existing nets require manual forming by workers, which is not only inconvenient but also prone to deviation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a peephole retrieval net and its forming and processing equipment to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A endoscopic retrieval net includes two nickel-titanium alloy wires, the central portions of the two nickel-titanium alloy wires are fixed to each other, the four ends of the two nickel-titanium alloy wires are fixedly connected to a connecting rod, and end caps are fixedly installed outward from the central fixed position of the two nickel-titanium alloy wires. The central portions of the two nickel-titanium alloy wires are fixed by a forming and processing equipment.

[0007] A forming processing device includes a processing table with an installation groove at its upper end. Four placement components are slidably connected inside the installation groove. The four placement components are driven to slide together by a transmission mechanism. Each placement component includes an arc-shaped plate slidably connected to the installation groove. The upper end of the arc-shaped plate has a wire groove. The four arc-shaped plates are close to each other on one side and have forming holes that match nickel-titanium alloy wires. A bending component is installed at the upper end of the processing table.

[0008] The transmission mechanism includes four transmission components. Each of the four transmission components includes a threaded rod that is threadedly connected to the arc-shaped plate. A transmission gear is fixedly installed on the threaded rod. A toothed ring that meshes with the four transmission gears is rotatably connected inside the processing table. Several meshing teeth are fixedly installed on the outer side of the toothed ring. A drive gear that meshes with the meshing teeth is rotatably installed inside the processing table. The drive gear is driven by a drive motor.

[0009] The bending assembly includes a mounting bracket fixed to the upper end of the processing table, a telescopic cylinder mounted on the upper end of the mounting bracket, a mounting plate mounted on the output end of the telescopic cylinder, and an abutment deformation rod fixedly mounted on the lower end of the mounting plate.

[0010] A spring is installed at the lower end of the mounting plate, and an abutment plate is installed at the lower end of the spring.

[0011] The upper end of the processing table is equipped with abutment components that match the four placement components. The abutment components include abutment rods that are rotatably connected to the processing table. The lower side of the abutment rods has a placement groove that matches the nickel-titanium alloy wire. An iron lifting ring is installed at the non-rotating connection end of the abutment rods. A magnet that attracts the iron lifting ring is installed at the upper end of the processing table.

[0012] This invention uses two nickel-titanium alloy wires fixed together to form four nickel-titanium alloy wires installed on the outside of the connecting rod. In the use of the endoscope, the four nickel-titanium alloy wires are used to clamp foreign objects. During the forming process, four arc-shaped plates can evenly fix the two nickel-titanium alloy wires. At the same time, the bending component and the sliding of the arc-shaped plates can make it easier to form the two nickel-titanium alloy wires. Attached Figure Description

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1: As Figure 1-7 As shown, the present invention provides a endoscopic retrieval net, comprising two nickel-titanium alloy wires 1, the central portions of the two nickel-titanium alloy wires 1 being fixed to each other, the four ends of the two nickel-titanium alloy wires 1 being fixedly connected to a connecting rod 11, and an end cap 12 being fixedly installed outward from the central fixed portion of the two nickel-titanium alloy wires 1, the central portions of the two nickel-titanium alloy wires 1 being fixed by a forming and processing equipment.

[0025] A forming processing device includes a processing table 2. The upper end of the processing table 2 is provided with an installation groove. Four placement components are slidably connected inside the installation groove. The four placement components are driven to slide together by a transmission mechanism. Each placement component includes an arc plate 21 slidably connected to the installation groove. The upper end of the arc plate 21 is provided with a wire groove 22. The four arc plates 21 are close to each other on one side and have forming holes 23 that match the nickel-titanium alloy wire 1. A bending component is installed on the upper end of the processing table 2.

[0026] The connecting rod 11 is installed together with the existing endoscope, thereby driving the retrieval net to move and retrieve objects inside the body. The end cap 12 can fix the two nickel-titanium alloy wires 1 by separating them in the middle, thereby making the two nickel-titanium alloy wires 1 into four nickel-titanium alloy wires 1, which not only saves materials but also facilitates processing and shaping.

[0027] Initially, the four arc-shaped plates 21 are far apart. During the forming process, two nickel-titanium alloy wires 1 are placed perpendicularly inside the four grooves 22, so that the two nickel-titanium alloy wires 1 are arranged vertically and cross each other at a 90-degree angle. Then, the two nickel-titanium alloy wires 1 are welded together at the intersection of their central overlapping points using the welding head of a welding machine in the prior art. After welding, the bending component causes the central part of the two nickel-titanium alloy wires 1 to deform and sink downward. Then, the transmission mechanism drives the four arc-shaped plates 21 to move closer to each other until the sides of the four arc-shaped plates 21 abut against each other and the four strands of nickel-titanium alloy wires 1 at the welded point of the two nickel-titanium alloy wires 1 abut against each other and are pressed tightly. After pressing, the transmission mechanism drives the arc-shaped plates 21 to return to their initial state, and then the end caps 12 are installed on the outside of the pressed nickel-titanium alloy wires 1.

[0028] This invention uses two nickel-titanium alloy wires fixed together to form four nickel-titanium alloy wires installed on the outside of the connecting rod. In the use of the endoscope, the four nickel-titanium alloy wires are used to clamp foreign objects. During the forming process, four arc-shaped plates can evenly fix the two nickel-titanium alloy wires. At the same time, the bending component and the sliding of the arc-shaped plates can make it easier to form the two nickel-titanium alloy wires.

[0029] Example 2: Based on Example 1, a further improvement is made. The transmission mechanism includes four transmission components. The four transmission components include a threaded rod 24 that is threadedly connected to the arc plate 21. A transmission gear 25 is fixedly installed on the threaded rod 24. A gear ring 26 that meshes with the four transmission gears 25 is rotatably connected inside the processing table 2. Several meshing teeth 27 are fixedly installed on the outer side of the gear ring 26. A drive gear 28 that meshes with the meshing teeth 27 is rotatably installed inside the processing table 2. A drive motor 29 is connected to the drive gear 28.

[0030] When the drive motor 29 drives its output shaft, it drives the drive gear 28 to rotate, which in turn drives the meshing teeth 27 and the gear ring 26 that mesh with it to rotate. Since the gear ring 26 meshes with the transmission gear 25, the rotation of the gear ring 26 will drive the transmission gear 25 and the threaded rod 24 to rotate. Since the threaded rod 24 is threadedly connected to the arc plate 21 and the arc plate 21 slides inside the mounting groove, when the threaded rod 24 rotates forward or backward, that is, when the drive motor 29 drives the drive gear 28 to rotate forward or backward, it will drive the arc plates 21 to move closer or further away from each other along the sliding direction. In this way, the forming hole 33 abuts and presses the recessed nickel-titanium alloy wire 1 part, so that the four strands of nickel-titanium alloy wire 1 at the fixed installation point can be pressed together to facilitate the subsequent installation of the end cap 12. The arc plates 21 moving away from each other makes it easy to remove the formed nickel-titanium alloy wire 1 and facilitate the next use.

[0031] The bending assembly includes a mounting bracket 30 fixed to the upper end of the processing table 2. A telescopic cylinder 31 is mounted on the upper end of the mounting bracket 30, and a mounting plate 32 is mounted on the output end of the telescopic cylinder 31. An abutment deformation rod 33 is fixedly mounted on the lower end of the mounting plate 32. The telescopic cylinder 31 drives the mounting plate 32 and the abutment deformation rod 33 to move downward, thereby abutting against the fixedly mounted nickel-titanium alloy wire 1 and moving downward, thus creating a depression that facilitates subsequent pressing of the depression.

[0032] A spring 34 is installed at the lower end of the mounting plate 32, and an abutment plate 35 is installed at the lower end of the spring 34. When the abutment plate rod 33 causes the nickel-titanium alloy wire 1 to be recessed, the abutment plate 35 first abuts against the arc plate 21, thereby overcoming the rebound force of the spring 34 and driving the abutment plate rod 33 to push the nickel-titanium alloy wire 1. After the nickel-titanium alloy wire 1 is recessed, the output shaft is retracted by the telescopic cylinder 31 to make the abutment deformation rod 33 flush with the arc plate 21. Under the rebound force of the spring 34, the abutment plate 35 is flush with the lower end of the abutment deformation rod 33. In this way, with the cooperation of the abutment deformation rod 33 and the abutment plate 35, the nickel-titanium alloy wire 1 inside the wire groove 22 is restricted to prevent it from tilting upward.

[0033] The upper end of the processing table 2 is equipped with abutment components that match the four placement components. The abutment components include abutment rods 36 that are rotatably connected to the processing table 2. The lower side of the abutment rods 36 is provided with placement grooves that match the nickel-titanium alloy wires 1. An iron lifting ring 37 is installed at the non-rotating connection end of the abutment rods 36. A magnet 38 that attracts the iron lifting ring 37 is installed at the upper end of the processing table 2. During installation, pulling the iron lifting ring 37 upwards opens the abutment rod 36, allowing the nickel-titanium alloy wire 1 to be placed inside the wire groove 22. Rotating the iron lifting ring 37 aligns the placement groove with the nickel-titanium alloy wire 1 until the iron lifting ring 37 and magnet 38 are attracted together. This limits the movement of the nickel-titanium alloy wire 1, facilitating welding. Simultaneously, when the bending component causes the nickel-titanium alloy wire 1 to be recessed, it slides within the placement groove, preventing the end of the nickel-titanium alloy wire 1 from tilting upwards during bending. The attraction of magnet 38 and iron lifting ring 37 further limits the movement of the nickel-titanium alloy wire 1.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
