1 TARIFF NON-SURGICAL TREATMENT FOR THE BREAKDOWN OF LARGE AND HARD GASTRIC GLANDURAL TUBES. ENDOSCOPIC CANNULA DESIGN TECHNICAL AREA 5 The invention addresses the need for surgical intervention in large and hard gastric bezoars. to enable the endoscopic disintegration of the tissue without being detected, using an endoscope A device that can be advanced through the biopsy channel, carrying basket wires and a metal head, metal It involves an endoscopic cannula consisting of a wire mesh section and a spiral tube. PREVIOUS TECHNIQUE Bezoars are structures that can form inside the stomach due to various reasons. Bezoars are structures that accumulate and form masses within the gastrointestinal system. The size and hardness of the bezoar are important in determining the treatment method to be applied. It is important. In current practices, chemical substances are used for the treatment of bezoars. or softening the bezoar using substances similar to Coca-Cola, endoscopically Methods such as breaking it into pieces or surgically removing it are used. Within the scope of known endoscopic treatments, through the biopsy channel of the endoscope The bezoar is removed using a water jet, forceps, snare, or basket-like apparatus that is advanced through the water. The aim is to break it down mechanically. These methods are particularly relevant in the 20s. Although it can be used to break up relatively small and soft bezoars, sufficient mechanical during the fragmentation of large and / or rigid bezoars Due to the inability to provide strength and support, the desired result cannot be achieved in every case. is unable to provide. The basket structures used in the endoscopic fragmentation of bezoars are 25 different. They can be created in various geometries and with different wire arrangements. The existing basket... In these systems, basketball hoops generally move inside a plastic cannula. This is done by placing the bezoar into basket wires, after which the wires are inserted into a cannula. By pulling it back inwards, a crushing force is created on the bezoar. However, especially during the disintegration of a large and hard bezoar, basket 30 A high force must be applied to retract the strings. This force creating high mechanical stress on the plastic cannula and the plastic cannula This can cause the plastic to tear or lose its mechanical support. In case of cannula rupture, the basket wires can be removed from either the cannula or the endoscope. 2 The biopsy channel does not receive sufficient mechanical support, and therefore the bezoar... The force required to break it apart cannot be applied effectively. This... As a result, the endoscopic dissection procedure may fail, and large and / or hard tissue may be found. Surgical intervention may be required in the treatment of bezoars. Another problem that arises in existing structures is higher fragmentation 5 using larger basketball structures suitable for the application of their forces The limitation is the mechanical strength of the cannula, especially for plastic cannulas. The system is susceptible to mechanical damage under high loads, leading to the development of hard bezoars. This limits its applicability. THE PURPOSE OF THE INVENTION The aim of the invention is to overcome the problems encountered in the previous technique. This allows for the endoscopic fragmentation of large and hard gastric bezoars. The goal is to develop a high-strength cannula structure that provides this. Another purpose of the invention is to enclose basketball strands inside a large, rigid bezoar. the forces that occur when it is withdrawn back into the cannula after it has been taken in the encounter of forces via the cannula and the breakdown of the bezoar The aim is to ensure that it is used effectively for its intended purpose. Another purpose of the invention is to prevent the stress that occurs when basketball hoops are pulled back. Compression of the metal wire mesh area under mechanical load and biopsy 20 of the endoscope by making contact with the channel, enabling it to receive mechanical support from that channel The goal is to obtain a cannula structure. Another aim of the invention is to ensure that the basketball hoops remain stable inside the cannula. the retention and pressure and pulling that occurs during the breakdown of the bezoar metal 25 which enables the creation of a connection zone resistant to forces The goal is to develop a structure with a title. Another objective of the invention is to ensure that the cannula is made of metal and has high strength. despite the fact that the endoscope could be advanced within the convoluted structure of the biopsy channel and It utilizes a flexible spiral hose structure that allows for retraction. Another aim of the invention is to eliminate the force applied to break up the bezoar. when lifted, the compressed metal wire mesh area returns to its free form. by ensuring the cannula's mobility within the endoscope is preserved to provide. 3 Another objective of the invention is to improve the mechanical strength of the cannula and the metal wire mesh. mechanical support provided through the biopsy channel of the endoscope via the region by increasing the size of the basketball structures, it is possible to use larger and more aggressive basketballs. The aim is to enable the bezoars to be broken down. Another aim of the invention is to break down large 5-core cells that are difficult to break down using endoscopic methods. and the breakdown of hard gastric bezoars without the need for surgical intervention by enabling the patient's treatment process to be shortened and long hospital stays to be avoided. to reduce, prevent surgical-related morbidity and related The aim is to reduce costs and labor losses.

It is coming. The subject of the invention is the gripping and breaking of the bezoar (6) by basket wires. (1) is carried out by means of. Basket wires (1), suitable for their intended use. It consists of more than one wire, and these wires are joined together by 15 wires. The wires are brought together in the region (2). The joining area of ​​the wires (2) is where the basketball wires come together. (1) moving together inside the cannula and opening the basket form or It ensures that the wires remain connected to each other when the power is turned off. When the basket wires (1) are retracted inside the cannula, the cannula It is located in a compressed position inside. The cannula is the biopsy channel of the endoscope 20 After being advanced through the cannula and delivered into the stomach, the basket wires (1) of the cannula It is advanced outwards from the distal side. Basket wires (1) out of the cannula By removing the wires, the wires are opened and a basket form into which the bezoar (6) can be placed. is occurring. The invention consists of a cannula with a metal head (3), a metal wire mesh section (4) and 25 It consists of a spiral tube (5). The regions in question are different parts of the cannula. They are interconnected to meet the working requirements. Metal head (3), The metal wire provides mechanical strength in the distal region where the basketball wires (1) are located. knitting region (4) forces occurring during fragmentation endoscope biopsy It allows transfer to the canal and the spiral hose (5) allows the cannula to be transferred to the endoscope 30 It adapts to the advancement and retraction movements within the biopsy channel. The metal cap (3) is located at the continuation of the wire joining area (2) and the metal wire mesh. It is located on the front of the region (4). The metal header (3) is positioned on the basketball wires (1) to maintain stability within the cannula and during the disintegration of the bezoar (6) It forms a resistant area where the mechanical forces that occur are resisted. The metal head (3) is made of metal material, a plastic cannula in the same area risk of tearing or mechanical deformation that may occur if used It helps to reduce [the decrease]. Following the metal head (3) is the metal wire mesh area (4). Metal 5 The wire mesh area (4) is shaped under flexible and mechanical load in a specific part of the cannula. It creates a modifiable buffer zone. The metal wire mesh in question... region (4), which occurs on the cannula during the withdrawal of the basket wires (1) It is structured in such a way that it can be compressed in the direction of the forces. The spiral hose (5) is located after the metal wire mesh area (4). Spiral 10 hose (5) is used to advance the cannula through the biopsy channel of the endoscope and back It creates a flexible region that allows for its stretching. Spiral structure thanks to the cannula, the curved or curved shape that the endoscope takes during use adaptable and nevertheless for carrying the basketball hoops (1) It maintains its integrity. 15 During use, the cannula, which is the subject of this invention, is inserted into the biopsy channel of the endoscope. It is being advanced. The bending capability of the spiral tube (5) allows the biopsy channel of the cannula to be extended. This ensures that it moves in accordance with its geometry. The distal end of the cannula After reaching the stomach, the basket wires (1) are pulled out of the cannula It is being advanced and by opening the basket wires (1) a basket that can surround the bezoar (6) 20 The structure is created. After the basketball wires (1) are opened, they are broken apart. The desired large and hard bezoar (6) is placed inside the volume created by the basket wires (1). It is taken. After the bezoar (6) is taken into the basket wires (1), the basket wires (1) are being pulled back into the cannula. The retraction of the basket wires (1) is the wires the narrowing around the bezoar (6) and the mechanical disintegration force on the bezoar 25 This leads to the application of the large and hard bezoar (6) of the basket wires (1). due to the mechanical resistance exhibited by the bezoar during its constriction around the basket Force (7) is generated on the wires (1) and the cannula. This force (7) is produced on the metal head. (3) is transferred to the region and the metal wire mesh region (4). The metal head (3) is high Thanks to its mechanical strength, the basketball wires (1) remain stable under the said force. It supports in this way. When the basketball hoops (1) continue to be pulled back The force transferred onto the metal wire mesh area (4) (7), the mesh structure in question This causes it to get stuck. As a result of the metal wire mesh area (4) getting stuck. The contact between the knitted area and the inner surface of the endoscope's biopsy channel and the cannula is increased. 6 It receives mechanical support from the biopsy channel. Thus, it is attached to the basketball wires (1) The pulling force applied (7) must be met not only by the cannula’s own structure, The biopsy channel of the endoscope also contributes through the metal wire mesh area (4) It is located. Mechanical interaction of the metal wire mesh area (4) with the biopsy channel, 5 high required during the breakdown of hard and large bezoars (6) It allows for the application of forces. This structure also enables basketball. It works by supporting its wires (1) by the metal head (3) and thus sufficient mechanical effect on the basket wires (1) to break the bezoar (6) It enables its creation. 10 In the working principle of the invention, the metal wire mesh area (4) is only a fixed one It does not function as a load-bearing area; its mechanical properties depend on the applied force. It creates a support zone whose behavior changes. The breakdown of the bezoar (6) The area of ​​metal wire mesh that is compressed under force during the biopsy of the endoscope (4) It receives support from the channel, the completion of the shredding process and the 15 on the basketball wires. (1) After the force (7) is removed, it becomes free and opens again. It returns to its form. Thanks to the variable structure dependent on this force (7), the cannula It provides mechanical support during dissection and movement within the endoscope. The preservation of its capability is achieved together. Metal wire mesh area (4) force Since it exhibits a more free structure when not present, the biopsy channel of the cannula is 20 It becomes easier to move it forward or backward inside. The crushing force. When applied, additional mechanical drainage is required through the biopsy channel due to compression of the same area. Support is being obtained. Mechanical strength of the metal head (3) and the shearing of the metal wire mesh area (4) under the force of the biopsy channel and the spiral tube (5) endoscope 25 When the mobility within it is considered together, the cannula that is the subject of the invention is large and can be used in the endoscopic fragmentation of hard gastric bezoars It forms an integrated structure. Thanks to the structure of the invention, large and rigid cannulas can be replaced with existing plastic cannulas. Tearing that can occur during the disintegration of bezoars and the resulting mechanical damage 30 The aim is to prevent loss of support. Provided by the metal head (3) strength and the area of ​​metal wire mesh (4) taken from the biopsy channel of the endoscope Mechanical support allows the use of larger basketball structures and a more rigid structure. It is made possible to break down bezoars. In this way, endoscopically 7 Large and hard gastric bezoars that are difficult to break down by conventional methods do not require surgery. This allows for treatment by breaking it down without leaving any residue. Thus, surgery intervention-related morbidity, long hospital stay, high treatment costs, and occupational problems The aim is to reduce loss of power and increase patient comfort. 10 20 30
