Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a capsule wall supporting micro-valve cap for endoscopic surgery of the digestive system. Background Art

[0002] With the continuous advancement of medical technology, endoscopic technology has become an important tool in the diagnosis and treatment of digestive system diseases. Compared with traditional surgical operations, minimally invasive endoscopic surgery has the advantages of less trauma, faster recovery, and fewer complications. The advancement of endoscopic technology has not only improved the accuracy of diagnosis, but also expanded the possibilities of treatment. For example, polypectomy, stent placement, tumor ablation and other treatments can be performed under endoscopy. These operations are usually more delicate and safer than traditional operations.

[0003] In addition, with the development of technology, the resolution and flexibility of endoscopic equipment have been continuously improved, allowing doctors to observe lesions under direct vision and perform precise interventions. This minimally invasive method reduces patients' pain and recovery time, while also reducing the risk of infection caused by surgery.

[0004] However, despite its obvious advantages, endoscopic surgery still faces some challenges in actual operation. When removing tumors in the digestive system, the edge of the tumor may be difficult to accurately identify due to the limited field of view provided by the endoscope, resulting in the collapse or movement of the tumor edge during the operation. This situation not only increases the difficulty of the operation, but may also affect the final outcome of the operation and even increase the risk to the patient.

[0005] At present, most endoscopic-assisted tools cannot effectively maintain the stability of tumors during surgery. On the one hand, the collapse or movement of the tumor edge makes the surgical operation more complicated and increases the risk of surgical failure. On the other hand, in order to maintain a clear field of view, the position of the endoscope may need to be continuously adjusted during the operation, which not only prolongs the operation time but also increases the difficulty of the doctor's operation. Therefore, it is particularly important to develop a new endoscopic-assisted tool that can stabilize the tumor edge during surgery while reducing the frequency of endoscope adjustment.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-3 The present invention provides a technical solution: a capsule wall supporting microvalve cap for endoscopic surgery of the digestive system, comprising an endoscope body 1, on which an auxiliary supporting mechanism 200 for supporting the mucosa and expanding the field of view is installed;

[0026] By cooperating with each other and providing a stable support platform for inflating the airbag, the tumor is ensured to be always in a relatively stable and easy-to-operate position during the operation, reducing the surgical risks of bleeding and damage to adjacent healthy tissues due to movement of the tumor. At the same time, it can maintain a clear line of sight during the operation without any obstruction. Its flat, curved and inclined design allows it to be easily placed in the patient's polyp, which not only improves the adaptability of the device, but also ensures that the device fits closely to the patient's body, reducing the number of adjustments required during the operation, thereby improving the efficiency and safety of the operation.

[0027] In this embodiment, the auxiliary supporting mechanism 200 is a structure used to ensure that the tumor is always kept in a relatively stable and easy-to-operate position during the operation.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, the auxiliary support mechanism 200 includes an expansion support assembly installed on a port on one side of the endoscope body 1 and a No. 1 connecting tube 202 and a No. 2 connecting tube 203 respectively connected to one side of the expansion support assembly, and the other ends of the No. 1 connecting tube 202 and the No. 2 connecting tube 203 are connected to an inflation assembly.

[0029] The two pumping components are connected to the expansion and propping component through the No. 1 connecting pipe 202 and the No. 2 connecting pipe 203. The expansion and propping component is expanded and propped up under the pressure of the pumping components.

[0030] The auxiliary support mechanism 200 is designed to effectively expand the surgical field of view by expanding the digestive tract mucosa. It can automatically expand the mucosa when performing tissue resection in the submucosal layer. This function not only provides a larger surgical field of view, but also can effectively expand the mucosa by physical means, so as to facilitate the precise execution of surgical operations.

[0031] It should be noted that the inflation component includes an inflation bag 2011, an air inlet 2012, an air release valve 2013 and an air guide tube 2014; one end of the air inlet 2012 passes through the inflation bag 2011 and is fixedly connected to the inner side of the inflation bag 2011, and one side of the air release valve 2013 is fixedly connected to the other side opposite to the inflation bag 2011, and the side of the air release valve 2013 away from the inflation bag 2011 is fixedly connected to one side of the air guide tube 2014. This is to enable the inflation bag 2011 to be inflated through the air inlet 2012 and the gas to be safely released through the air release valve 2013. By controlling the inflation bag 2011 and the air release valve 2013, the pressure in the inflation bag can be accurately controlled to ensure safe use, so that the operator can accurately control the expansion degree of the expansion and support component according to surgical requirements, and realize precise control of support and field of view expansion. This manual control method provides great flexibility and precision for the surgical operator, ensuring the smooth progress of the surgical process.

[0032] It can be understood that one end of one of the air guide tubes 2014 away from the air release valve 2013 is fixedly connected to one end of the No. 1 connecting tube 202, and the other end of the air guide tube 2014 away from the air release valve 2013 is fixedly connected to one end of the No. 2 connecting tube 203. This is to ensure the fluidity of the gas when it is pressurized, so as to ensure that the expansion support component can work normally, and to play a role in regulating and inflating the expansion support component. The expansion of the expansion support component is achieved by regulating and inflating, so as to achieve appropriate stretching of the mucosa in the surgical area, thereby optimizing the surgical operating environment. This design not only improves the accuracy of the operation, but also ensures the clarity of the surgical field of view, and provides a good operating platform for the surgical operator.

[0033] In addition, the expansion support assembly includes a mounting ring 2041, a transparent hollow cap body 2042 and a support airbag 2043; the inner side of the mounting ring 2041 is fixedly mounted at the outer port of the endoscope body 1, and one side of the transparent hollow cap body 2042 is fixedly mounted on the side of the mounting ring 2041 away from the endoscope body 1. The outer side of the support airbag 2043 is mounted on the inner side of the transparent hollow cap body 2042. There are two transparent hollow cap bodies 2042 and they are distributed in a mirror-symmetrical manner. The transparent hollow cap body 2042 is made of highly transparent material to ensure that the surgical field of view is clear. The transparent hollow cap body 2042 has a certain rigidity to maintain its shape stability, ensuring that while providing effective inflation for the support airbag 2043, it will not interfere with the field of view of the endoscope and can maintain a stable shape during the operation.

[0034] In this embodiment, the transparent hollow cap body 2042 is flat and arc-shaped, and the two transparent hollow cap bodies 2042 are inclined at a certain angle in opposite directions, so that they can be easily placed in the patient's polyps, which not only improves the adaptability of the device, but also ensures that the device fits closely with the patient's body.

[0035] It should also be noted that the interior of the transparent hollow cap body 2042 is hollow, and the two opposite sides of the transparent hollow cap bodies 2042 are provided with mounting holes 205 for the support airbag 2043 to pass through. This is to enable the support airbag 2043 to be connected to the transparent hollow cap body 2042 through the mounting hole 205, and during the operation, the support airbag 2043 can be inflated to provide a stable support platform, which not only provides a stable support point for the tumor, but also can effectively expand and stretch the tumor during the operation. In this way, the operator can observe the structure of the tumor more clearly, and at the same time create favorable conditions for subsequent resection or treatment work, improve the efficiency of the operation, and ensure the safety and accuracy of the operation. By precisely controlling the inflation and deflation of the support airbag 2043, the doctor can flexibly adjust the position and shape of the tumor during the operation, so as to better adapt to the needs of the operation.

[0036] The working principle of the above embodiment is:

[0037] 1. Preparation stage:

[0038] Before the operation begins, ensure that all devices have been inspected by professionals to confirm that they are functioning properly without damage or leakage. Place the endoscope body 1 into the patient's body through an appropriate route to ensure that the endoscope can reach the surgical area. Adjust the auxiliary support mechanism 200 to ensure that the expansion support assembly is in a ready-to-work state. At the same time, check whether the inflation assembly is intact, including the functionality of components such as the inflation bag 2011, the air inlet 2012, the air release valve 2013 and the air guide tube 2014.

[0039] 2. Entering the body:

[0040] The transparent hollow cap (2042) enters the patient's body through the endoscope body 1 and reaches the predetermined surgical area, ensuring that the endoscope body 1 is stable and correctly aligned with the surgical area so that the auxiliary support mechanism 200 can work effectively.

[0041] 3. Resection of tumor:

[0042] During the operation, the operator applies pressure by controlling the pressing and punching of the airbag 2011, and delivers external air to the airway 2014 through the air inlet 2012 and transmits it to the No. 1 connecting tube 202 and the No. 2 connecting tube 203. The No. 1 connecting tube 202 and the No. 2 connecting tube 203 are respectively connected to the two sides of the mounting fixing ring 2041. As the gas is injected, the supporting airbag 2043 expands and props up, stretching the digestive tract mucosa, thereby expanding the surgical field of view. The stretched mucosa provides a larger operating space for the operation, allowing surgical instruments to more easily approach and remove the tumor. During the resection process, the transparent hollow cap 2042 keeps the tumor stable, preventing it from moving during the operation, and ensuring the accuracy of the operation.

[0043] 4. Complete the resection:

[0044] After removing the tumor, the operator controls the deflation valve 2013 to release the gas, and safely discharges the gas in the support balloon 2043 through the deflation valve 2013, causing the expansion support balloon 2043 to retract and return to its original state. Finally, the endoscope body 1 and the expansion and support assembly are taken out of the body together, completing the entire surgical process.

[0045] Compared with the existing technology: the capsule wall supports the micro-flap cap for endoscopic surgery of the digestive system, through the mutual cooperation between the auxiliary support mechanism 200 on the endoscope body 1, by inflating the airbag to provide a stable support platform, ensuring that the tumor is always in a relatively stable and easy-to-operate position during the operation, reducing the surgical risks of bleeding and damage to adjacent healthy tissues due to movement of the tumor, and at the same time, being able to maintain a clear line of sight during the operation without any obstruction. Its flat, arc-shaped and inclined design enables it to be easily placed in the patient's polyp, which not only improves the adaptability of the device, but also ensures that the device fits closely to the patient's body, reducing the number of adjustments required during the operation, thereby improving the efficiency and safety of the operation, and solving the problems of difficult to accurately identify and stabilize the edge of the tumor, complicated surgical operation and affected visual clarity in existing endoscopic surgery.

[0046] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
