Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and in particular to an endoscopic stone removal basket device and a method for using the same. Background Art

[0002] Endoscopes are inspection instruments that integrate technologies from multiple fields, including traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. They can enter the body through natural orifices or small surgical incisions. They can be categorized as rigid or flexible. Rigid instruments, such as cystoscopes and laparoscopes, have fixed structures, while flexible instruments, such as gastroscopes and colonoscopes, have flexible bodies and tips. They primarily utilize a charge-coupled device (CCD) at the tip to convert optical signals into electrical signals, which are then processed and displayed on a monitor. In the medical field, they are used for diagnosis and surgery in various departments, including gastrointestinal, urological, and thoracic surgery. In the industrial field, they can provide indirect visual inspection of the interior of equipment. Since its origin in 1795, continuous technological innovation has continuously driven development in various fields. Endoscopic lithotripsy is a minimally invasive procedure for removing stones with the help of an endoscope. Taking endoscopic retrograde cholangiopancreatography lithotripsy as an example, the doctor first passes the duodenoscope through the mouth, esophagus, and stomach to the descending duodenum, finds the duodenal papilla, inserts a tube to inject contrast agent, and determines the location, size, and number of stones in the common bile duct. The stones are then removed using instruments such as a basket and a balloon. In addition, there are also ureteroscopic lithotripsy and cystoscopic lithotripsy. This procedure has minimal trauma, fast recovery, and relatively few complications, but there are also risks such as bleeding, infection, and perforation. The endoscopic lithotripsy basket is a surgical instrument used in conjunction with an endoscope to remove stones or foreign bodies from the body. The basket wire is mostly a metal woven structure that can trap and capture targets to prevent stones from slipping. Some use memory alloys that are repeatedly stretched and not easily deformed, which can improve stone removal efficiency and shorten operation time. Traditional surgical treatment of stones often results in large incisions, causing serious damage to the patient's body and a long recovery period. Even some relatively minimally invasive existing technologies often seem powerless when faced with complex stone situations. When operating in narrow human ducts, it is difficult to accurately locate and grasp stones, which can easily cause residual stones and require a second operation, adding to the patient's pain. To this end, we propose an endoscopic stone removal basket device and its use method. Summary of the Invention A solved problem

[0003] In response to the shortcomings of the existing technology, the present invention provides an endoscopic stone removal basket device and a method for using the same, which solves the problem that the existing traditional surgical treatment of stones often causes large wounds, serious damage to the patient's body, and a long recovery period. Even some relatively minimally invasive existing technologies often seem powerless when faced with complex stone situations. When operating in narrow human channels, it is difficult to accurately locate and grasp stones, which can easily cause stone residues and require a second operation, adding to the patient's pain. Second technical solution

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an endoscopic stone removal basket device and a method of using the same, comprising a handle shell, an inner wall of the handle shell being inserted with a handle body, one end of the handle shell being fixedly connected to a fixed handle assembly, a surface of the fixed handle assembly being provided with a thread, one end of the fixed handle assembly being threadedly connected to a handle back cover, an end of the handle shell away from the handle back cover being threadedly connected to a handle front cover, an end of the handle body close to the handle front cover being fixedly connected to a movable handle assembly, a surface of the handle front cover being fixedly connected to a protective sheath tube, an inner wall of the protective sheath tube being provided with an outer sheath tube, an inner wall of the outer sheath tube being provided with a hose sheath tube, an inner wall of the hose sheath tube being provided with an inner core, one end of the inner core being fixedly connected to a basket head, the protective sheath tube being provided to protect the internal structure, being provided outside the outer sheath tube, and being effectively prevented from being damaged by external friction, extrusion, etc. during operation, thereby preventing deformation and damage of the internal components due to external forces, and ensuring that the basket head can operate normally.

[0005] Preferably, the mesh basket head is made of nickel-titanium alloy, and the outer sheath and hose sheath are made of polyetheretherketone. By setting the mesh basket head, the three key aspects of stone grasping and fixation, stone crushing assistance, and adaptation to the human body cavity are mainly reflected. The stone can be accurately grasped and fixed. The mesh basket head can open and cover the stone, and firmly fix the stone by contraction, ensuring that the stone will not fall off during the removal process, providing protection for safe stone removal.

[0006] Preferably, the sheath tube is made of polyurethane, and the handle body is made of acrylonitrile-butadiene-styrene. By setting the handle body, the ABS material has the hardness and chemical resistance of acrylonitrile, the toughness of butadiene, and the gloss and processability of styrene, so that it has high hardness and strong impact resistance, can withstand extrusion and collision during use and is not easily damaged, has a smooth surface and is easy to process and shape, and can be made into various shapes according to design requirements, which is convenient for the structural design and function realization of the handle body, has good chemical corrosion resistance, can resist the erosion of common disinfectants, detergents and other chemical substances in the medical environment, is easy to clean and disinfect, meets the hygiene requirements of medical equipment, has certain heat resistance, can be used stably within the appropriate temperature range, and has good insulation performance to ensure the safety of circuit components in the handle body. At the same time, the material is relatively light, which can reduce the overall weight of the handle and improve the comfort and convenience of medical staff during operation.

[0007] Preferably, a switch is installed on the upper surface of the handle body, and anti-slip grooves are provided on the surface of the handle body.

[0008] Preferably, the inner core and the soft tube sheath are telescopically slidable, and the outer sheath is made of a soft material and is bendable.

[0009] Preferably, the switch on the upper surface of the handle body can control the opening and closing of the basket head, and the upper surface of the handle body is provided with a protrusion for placing fingers.

[0010] Preferably, S1. Preoperative preparation: Based on the type of endoscope used, the size of the stone, and the location of the stone removal, select a basket head of specifications such as Olympus UCR-3S-1 or Cook CB-STONE-3F. Carefully check whether the product packaging is intact. If the packaging is damaged or the product is damaged, it is strictly prohibited to use it. Open the package and take out the basket head. Use the switch on the control handle to test whether the basket head can open and close smoothly. It can only be used after confirming that there is no abnormality. S2. Intraoperative operation: Use the switch on the handle to adjust the basket head to the closed state. After the basket head is completely closed, insert the basket head into the body through the working channel of the endoscope and slowly push it to the vicinity of the stone. Push the handle switch to fully open the basket head and insert the stone into the center of the basket head. Push the handle switch again to retract the basket head until the stone is completely fixed. If the stone is too large, laser lithotripsy can be used after the basket head fixes the stone. Fix the handle to ensure that the stone is firmly trapped. Finally, slowly withdraw the endoscope and basket head together from the cavity. S3. Postoperative treatment: After removing the device, clean, disinfect and maintain it, dispose of medical waste according to standard procedures, closely observe the patient's postoperative reactions, such as whether complications such as bleeding and infection occur, and keep corresponding records.

[0011] In summary, the technical effects and advantages of the present invention are as follows: In the present invention, according to the type of endoscope used, the size of the stone and the location of the stone removal, a basket head of specifications such as Olympus UCR-3S-1 or Cook CB-STONE-3F is selected. The product packaging is carefully checked to see if it is intact. If the packaging is damaged or the product is damaged, it is strictly prohibited to use it. Open the package and take out the basket head. By controlling the switch on the handle body, test whether the basket head can be opened and closed smoothly. It can be used only after confirming that there is no abnormality. Use the switch on the handle body to adjust the basket head to the closed state. After the basket head is completely closed, the basket head is inserted into the body through the working channel of the endoscope and slowly pushed to the vicinity of the stone. Push the handle switch to fully open the basket head and insert the stone into the center of the basket head. Push the handle switch again to retract the basket head until the stone is completely fixed. If the stone is too large, laser lithotripsy can be used after the basket head fixes the stone. Fix the handle to ensure that the stone is firmly fixed. Finally, slowly withdraw the endoscope and basket head together from the cavity. After the device is removed, it is cleaned, disinfected and maintained, medical waste is handled according to standard procedures, and the patient's postoperative reactions are closely observed, such as whether complications such as bleeding and infection occur, and corresponding records are kept. By setting up the present invention, during the operation, the basket head of suitable specifications and models is accurately selected and strictly tested, and the opening and closing of the basket head is accurately controlled in conjunction with the handle switch, which can accurately locate and fit the stones and achieve fine operation. The handle shell is tightly connected and stably assembled with each component to ensure that the device operates stably throughout the operation without being interfered with by human tissue. The structural design of the hose sheath, inner core, etc. enables the basket head to flexibly penetrate into the complex cavity to reach the stone site, and the basket head can be quickly opened and closed and recovered, combined with efficient lithotripsy, which greatly shortens the operation time. The nickel-titanium alloy basket head, polyetheretherketone sheath and other materials, combined with the gentle operation method, minimize damage to tissues and reduce the risk of intraoperative bleeding, fully realizing the advantages of fine, stable, flexible, fast and less bleeding in the operation process.
