Endoscopic anchoring clips eac

Abstract

The Endoscopic Anchoring Clip (EAC) represents a breakthrough in the field of endoscopic clips, offering a safe and secure solution for fixation and anchoring barriers, tubes and devices inside body. Crafted from high-quality and stable materials which not affected by acid and alkaline and not carcinogenic such material like titanium and polyurethanes, the EAC is designed to piercing targeted tissue with precision and maintain a secure fixation of tubes, barriers, and medical devices. Its unique design does not cause ischemia by ensuring that blood flow to the grasped tissues remains unaffected, making it ideal for anchoring devices and management of mucosal defect and fistulas The EAC can be used in endoscopic, laparoscopic and open procedures and is applicable to be applied to the skin. Furthermore, the clip can be easily removed when indicated, allowing for flexible fixation durations.

Description

[0001] Description

[0002] Title of the innovation: Endoscopic Anchoring Clips EAC

[0003] Field of the invention:

[0004] Endoscopic clips have a crucial role in endoscopic interventions such as for bleeding and closure of the mucosal defect after endoscopic mucosal resection.

[0005] EAC is an invention in the field of endoscopic clips and has a unique property which not causing ischemia and stay for a long period of time

[0006] Background of innovation:

[0007] Endoscopic clips are widely used in medical procedures, particularly in managing endoscopic gastrointestinal bleeding, approximating mucosal defects after endoscopic mucosal resection (EMR), and can be used in conditions such as gastrointestinal and rectovaginal fistulas. The retention time of these clips varies depending on the type and orientation during application, typically ranging from 1 to 4 weeks. One of the most important factors influencing the clip's retention time is decreased blood supply and necrosis that occurs in the tissue grasped by the clip arms due to reduced blood flow.

[0008] General Applications of Endoscopic Clips:

[0009] 1. Gastrointestinal Bleeding Management: Endoscopic management of Gl bleeding is one of the fundamental way and endoscopic clips play an important role

[0010] 2. Mucosal Defect Approximation: Following endoscopic mucosal resection (EMR), the defect can be approximated using endoscopic clips.

[0011] 3. Fistula Management: sealing the fistula opening by clips will assist in its complete closure such as enterocutaneous and rectovaginal fistula common Types of clips

[0012] 1 -Traditional Endoscopic Clips:

[0013] - Retention Time: Typically lasts between 1 to 4 weeks.

[0014] - Mechanism of action: it works by grasping or approximation the mucosa tightly and this will cause decrease in diminished blood supply

[0015] -Applications: Primarily used for control of bleeding and closure of mucosal defects.

[0016] - Flexibility: Generally, low flexibility for long-term use due to dislodgment and generally not use for secure anchoring.

[0017] - Removal: dislodged naturally due to tissue necrosis, generally no need intervention for removal.

[0018] 2- Specialized Clips:

[0019] A- Ovesco Clips (OTSC):

[0020] - Retention Time: Can remain in place for long periods (weeks to months).

[0021] - Mechanism: has strong gripping and suction forces, making them effective in closing large defects.

[0022] - Flexibility: effective in emergency situations and severe Gl bleeding

[0023] - Removal: Can be removed endoscopically using specialized instrument

[0024] B- Hemoclips:

[0025] - Retention Time: usually remains in place for several weeks.

[0026] - Mechanism: Designed to tightly grasp the mucosal to stop bleeding.

[0027] - Applications: Primarily used for control of bleeding.

[0028] - Flexibility: short term uses due to dislodgment.

[0029] - Removal: usually dislodges over time.

[0030] Technical problems:

[0031] Dislodgment of the clips is one of the most important problem of clips and to great extend it related to decrease or diminished blood supply to grasped part

[0032] This limits their use as an anchoring for devices and tubes Solution to problems:

[0033] EAC will remain in place for a long period of time with ability to remove it when indicated, as it does not cause ischemia to the clipped part and suitable for approximation of mucosal defects and fistula management as blood supply not compromised and this is due to its unique design and application

[0034] And it’s suitable for anchoring tubes and devices.

[0035] Brief Description of the Drawings and Figures:

[0036] Figure 1 : illustrates the endoscopic anchoring clips, clips consisting of two arms. One of the arms is equipped with a sharp tip, which is highlighted in the figure. This sharp tip is designed to penetrate the target tissue during application. The figure shows the structure of the clip, especially the function of the sharp tip in tissue penetration.

[0037] Figure 2: emphasize the endoscopic anchoring clip (EAC) with a slot in one of the arms. This slot is designed to receive the sharp tip of the other arm when the clip is applied. The slot facilitates precise and secure closure of the clip on the tissue, enhancing the effectiveness and stability of the tubes or barriers anchored by this clip.

[0038] Figure 3: shows the endoscopic anchoring clip (EAC) in use, securing a barrier within the stomach. The figure shows the meeting point of the two arms at the anchoring site and highlights the area between the arms where they do not fully adhere, preventing ischemia in the grasped tissues. This design ensures the preservation of blood flow to the tissue, reducing the risk of ischemia on the tissue grasped by the clip.

[0039] General Description of the invention:

[0040] Endoscopic Anchoring Clips are advanced clips, designed for use in endoscopic procedures and special forms can be used for laparoscopic and open procedures. These clips consist of two arms: one semicircular sharp tip arm and one more straight arm with hole at the tip, where the sharp arm is received into the hole in the other arm when the clip is applied.

[0041] Components of the Invention:

[0042] 1. Design and Materials:

[0043] - Materials: The clips can be made from materials with similar properties, such as high strength, resistance to acidity and alkalinity, and biocompatibility, ensuring no adverse tissue reactions such as titanium or polyurethanes or any other material with similar property

[0044] - Design: The clip features one semi-circular arm and one straight arm:

[0045] - The first arm is sharp, allowing it to penetrate tissues.

[0046] - The second arm has a hole at its tip, designed to receive the sharp arm, ensuring stable and secure fixation.

[0047] 2. Mechanism of Action:

[0048] - Application: When applied, the sharp arm penetrates the tissue with minimal damage received by the hole in the other arm. Both arms do not adhere together in their long axis thereby preventing tissue necrosis. This design ensures long-term stability.

[0049] - Usage: The clip can be used for long periods, either temporarily or permanently, as indicated

[0050] 3. Functions and Uses:

[0051] Endoscopic Anchoring Clips are used to fix and secure medical devices, tubes, and barriers within the body for short and long periods, and for closure of fistulas and mucosal defects

[0052] 4. Removal

[0053] - Endoscopic Removal: The clip can be removed endoscopically when necessary, using double channel OGD with an endoscopic grasper and by reattaching the clip to the distal handle.

[0054] Professional Benefits: - not affect blood supply: The design of the clip does not cause ischemia and mucosal necrosis, ensure safe and effective anchoring and insure good blood supply to mucosal edges in mucosal defect approximation.

[0055] - used as long term: These clips can remain in place for long periods, making them ideal for both permanent and temporary applications.

[0056] - Applicable Removal: The clips can be removed when needed with endoscopy, providing flexibility in management with no or little complication.

[0057] These characteristics make Endoscopic Anchoring Clips (EAC) a good choice for anchoring devises and tubes and closure of mucosal defects
