Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a gastrointestinal polyp resection device and its usage method. Background Art

[0002] Gastrointestinal polyp resection is a common surgery for treating gastrointestinal diseases. Traditional treatment methods mainly rely on endoscopic techniques. Through an endoscopic device with a diameter of about 10 - 12 mm, doctors can locate, resect polyps, and retrieve specimens within the gastrointestinal tract. This technology has been widely applied in clinical practice and achieved certain therapeutic effects. Endoscopic devices are usually equipped with a high-precision image acquisition system and operating tools, which can help doctors precisely resect polyps and perform postoperative hemostasis and other treatments. However, despite the development of endoscopic treatment for many years, the operation process still requires the patient to undergo general anesthesia or deep sedation to ensure the smooth progress of the treatment.

[0003] Although existing gastrointestinal polyp resection methods have achieved certain clinical applications, there are still some problems that cannot be ignored. First, traditional endoscopic devices require general anesthesia or deep sedation, and patients may experience discomfort symptoms such as nausea and vomiting during the operation, and may also develop complications such as throat injury after the operation. Second, due to certain defects in the specimen retrieval system of traditional endoscopic devices, multiple polyps are prone to cross-contamination during the retrieval process, resulting in specimen fragmentation, which not only increases the difficulty of pathological diagnosis but also has a relatively high misdiagnosis rate. In addition, the hemostasis technology of traditional methods highly depends on the operator's experience, and the instability of electrocoagulation hemostasis technology makes some patients at risk of delayed bleeding. At the same time, the wound surface is exposed to digestive tract contents, increasing the probability of postoperative infection. Finally, due to the relatively single function of traditional devices, it is often necessary to frequently replace tools to complete different treatment tasks, which increases the treatment time, exacerbates the patient's discomfort, and makes the treatment process more complex. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a gastrointestinal polyp resection device and its usage method, which solve the problems of high anesthesia risk, specimen cross-contamination, postoperative complication risk, and single function of instruments existing in traditional gastrointestinal polyp resection techniques.

[0044] The present invention provides a gastrointestinal polyp resection device and a method of using the same. It has the following beneficial effects:

[0045] 1. The capsule-type gastrointestinal polyp treatment device composed of the upper shell and the lower shell of the present invention uses a traction rope to guide the device into the patient's body, avoiding the deep anesthesia or sedation required for traditional endoscope insertion, reducing the discomfort of the patient during the operation, and reducing the risks brought by general anesthesia or sedation. Compared with the endoscope used in the prior art, it solves the problems of nausea, vomiting and postoperative throat injury that are prone to occur in the traditional method.

[0046] 2. The present invention seals multiple resected polyps in different areas through a partition, effectively avoiding the risk of cross-contamination of polyps in the same instrument channel. Each polyp sample can be stored independently, maintaining its integrity, reducing the adhesion or fragmentation of polyps after resection. Compared with the risks of specimen cross-contamination and misdiagnosis existing in the prior art, it solves the problems of difficult pathological diagnosis and a misdiagnosis rate as high as 15% caused by specimen fragmentation in the traditional method.

[0047] 3. The present invention combines a micro forceps and a high-frequency electrocautery knife for polyp resection, and is equipped with an automatic hemostasis function, reducing the dependence of the operator's experience on the hemostasis effect. This device can accurately perform resection and hemostasis, avoiding the problem of delayed bleeding in some cases caused by unstable electrocoagulation hemostasis technology in traditional methods. At the same time, the postoperative wound can be promptly irrigated with normal saline and treated with hemostatic gel, greatly reducing the risk of postoperative infection and the infection rate caused by the exposure of the wound surface to digestive tract contents.

[0048] 4. The central hub of the present invention integrates multiple functions such as polyp resection, specimen storage, and hemostasis treatment, avoiding the inefficient operation of frequently changing tools in existing devices. Multiple components within the device work together, and one operation can complete resection, hemostasis, specimen storage, and postoperative treatment. Compared with the devices with only a single function in the prior art, the operation time is reduced, and the treatment efficiency is greatly improved, solving the deficiencies of traditional devices with a single function and frequent tool replacement.

[0061] Please see attached Figure 1 -Attached Figure 5 The embodiment of the present invention provides a gastrointestinal polyp removal device and a method of using the same, including:

[0062] The lower shell 1, which serves as the main body of the device and is used to store the spraying components;

[0063] An upper shell 2, which is arranged on the top of the lower shell 1 and is used to store the cutting assembly;

[0064] A storage plate 5 is arranged inside the upper shell 2 and has a groove for storing the lifting door 6, so as to provide a storage space for the lifting door 6 when it is lowered;

[0065] The partition 7 is fixed inside the upper shell 2 and is provided with a pH sensor inside, which is used to separate a plurality of closed and unconnected spaces and detect the pH value at the same time;

[0066] A central hub 10, which is disposed between the lower shell 1 and the upper shell 2, and is used to control the operation of the entire equipment structure;

[0067] A monitoring probe 11, which is disposed on the top of the central hub 10 and is used to view the specific conditions in the stomach and intestines using an image display;

[0068] A traction rope 24, which is arranged at the bottom of the lower shell 1 and is used to pull the device;

[0069] A rotating assembly, which is disposed between the lower shell 1 and the upper shell 2 and is used to control the rotation of the upper shell 2;

[0070] The cutting assembly includes a clamping jaw 8, which is arranged inside the upper shell 2, and the clamping jaw 8 is electrically connected to the central hub 10, and a high-frequency electric cutter 9 is arranged in the middle of the clamping jaw 8;

[0071] The rotating assembly includes a receiving ring 3, which is fixed to the outer wall of the lower housing 1. A rotating ring 4 rotates inside the receiving ring 3. A first rotating shaft 13 driven by a motor is arranged inside the receiving ring 3. A gear 14 is fixed to the outer wall of the first rotating shaft 13. A toothed ring 15 is fixed to the outer wall of the rotating ring 4. The first rotating shaft 13 meshes with the toothed ring 15. The rotating ring 4 is connected to the upper housing 2.

[0072] The spraying assembly includes a fixed frame 16, which is fixed inside the lower housing 1. A second rotating shaft 17 driven by a motor is arranged inside the fixed frame 16. A roller rod 18 is fixed to one side of the outer wall of the second rotating shaft 17, and a limiting rod 19 is fixed to the other side of the outer wall of the second rotating shaft 17.

[0073] A first capsule 20 is arranged inside the lower housing 1. A second capsule 21 is arranged on one side of the first capsule 20. Both ends of the first capsule 20 and the second capsule 21 are fixed with a conveying pipe 22. The conveying pipe 22 is in contact with the roller rod 18 and winds around the inner wall of the fixed frame 16. Both ends of the conveying pipe 22 far from the first capsule 20 and the second capsule 21 are fixed with a conveying head 23. The conveying head 23 is electrically connected to the central hub 10. The conveying head 23 is fixed inside the lower housing 1.

[0074] A scraper 12 driven by a motor is arranged inside the central hub 10. The scraper 12 touches the surface of the monitoring probe 11.

[0075] Specifically, the device enters the patient's gastrointestinal tract through the towing rope 24. With the help of the monitoring probe 11, the precise position of the device is tracked in real time to ensure that the device reaches the area to be treated. Once the positioning is completed, the central hub 10 controls the lifting hatch 6 to gradually descend, opening the cutting operation space to ensure that the clamping jaw 8 can extend smoothly and be ready to work.

[0076] Once the clamping jaw 8 is deployed, it starts to precisely grasp the target polyp and uses the high-frequency electrocision knife 9 to excise it. After the high-frequency electrocision knife 9 completes the task, it automatically shuts down. The clamping jaw 8 quickly retracts and firmly grasps the excised polyp, avoiding any secondary scattering and tissue damage. These excised polyps are then sent into the upper housing 2. Through the partitioning function of the partition 7, different polyp samples are clearly partitioned to prevent cross-contamination and maintain a good storage state.

[0077] To more efficiently utilize the space and process multiple cutting areas, the first rotating shaft 13 drives the gear 14 to rotate, and the toothed ring 15 further rotates the upper housing 2 to make it rotate. In this way, the device completes cutting operations at different positions without displacement, providing a new space for each excision.

[0078] After the resection is completed, the central hub 10 controls the rotation of the second rotating shaft 17, driving the roller rod 18 to precisely squeeze the delivery tube 22. The vacuum suction generated is used to suck the hemostatic gel in the second capsule 21 and accurately spray it onto the wound area through the delivery tube 22. During this process, the device also detects the environmental pH value. If the detected pH is greater than 6, it automatically releases an oxidant for acid resistance to avoid damage to tissues caused by an overly acidic environment and ensure the treatment effect.

[0079] Please refer to the appendix Figure 6 - Appendix Figure 9 , the inside of the central hub 10 includes:

[0080] The pH environmental perception module is used to continuously monitor the pH value of the gastrointestinal environment in real time, determine the position of the device, and accordingly control behaviors related to environmental response, such as the opening / closing of the hatch 6 and the selection of the type of postoperative treatment liquid;

[0081] The delivery path control module is used to select a suitable liquid from the first capsule 20 or the second capsule 21 according to the pH judgment result or the surgical process status and accurately deliver it to the surgical area;

[0082] The surgical navigation and decision-making module is used to combine infrared multi-spectral images and inertial navigation data to achieve precise positioning of polyps in the gastrointestinal tract, boundary judgment, and safe resection path planning;

[0083] The pH environmental perception module includes:

[0084] The pH microsensor unit is arranged on the internal partition 7 of the capsule and is used to detect the real-time pH value in the digestive tract;

[0085] The data acquisition unit is used to record and upload the pH data to the central processing unit;

[0086] The pH threshold judgment unit is used to compare the pH value with the set threshold to control the opening or closing of the lifting hatch 6;

[0087] The delivery path control module includes:

[0088] The liquid storage source selection unit is used to select to connect the first capsule 20 to release normal saline or the second capsule 21 to release hemostatic gel according to the pH value judgment result or the intraoperative state;

[0089] The micro peristaltic pump drive unit is used to control the rotation speed of the second rotating shaft 17, thereby driving the roller rod 18 to precisely adjust the delivery speed and flow rate;

[0090] The delivery path switching valve group is used to judge whether to perform delivery and control whether the position of the delivery head 23 is opened;

[0091] The surgical navigation and decision-making module includes:

[0092] An infrared multi-spectral imaging acquisition unit for acquiring images of the target area through the monitoring probe 11;

[0093] An inertial navigation unit for calculating the three-dimensional position of the device in the gastrointestinal tract;

[0094] An AI-assisted determination unit with a built-in training model for judging the polyp boundary and resection path and outputting a surgical execution instruction;

[0095] A control signal distribution unit connected to the jaw 8 and the high-frequency electrotome 9 to achieve precise control;

[0096] A cleaning unit for driving the scraper 12 to remove the attached mucus according to the image clarity.

[0097] Specifically, the pH environment perception module monitors the pH value in the gastrointestinal tract in real time, judges the current environment and feeds back to the central hub 10. The core function of this module is to identify environmental changes and provide a decision-making basis for other modules. For example, when the pH value is low, it may indicate that the device is in the stomach, while a higher pH value indicates that the device has entered the intestine. Based on this judgment, the delivery path control module will automatically select the appropriate liquid, such as releasing normal saline from the capsule one 20 or releasing hemostatic gel from the capsule two 21 for subsequent treatment. The cooperation between this module and the pH environment perception module ensures the precise delivery of the liquid and avoids the selection of the wrong liquid.

[0098] At the same time, the surgical navigation and decision-making module combines the information from the infrared multi-spectral imaging acquisition unit and the inertial navigation unit to provide precise polyp positioning and resection path planning. Based on the image and position information, this module accurately determines the boundary of the polyp to ensure that the surrounding tissues are not damaged during resection. It closely cooperates with the delivery path control module and the pH environment perception module to ensure that while precisely resected, it can timely judge whether liquid delivery or other treatment operations are needed.

[0099] In addition, the surgical navigation and decision-making module also transmits instructions to the jaw 8 and the high-frequency electrotome 9 through the control signal distribution unit to ensure the efficient execution of the resection operation. At the same time, if there is any mucus or other interfering substances affecting the image clarity during the operation, the cleaning unit will automatically drive the scraper 12 to clean according to the image quality to keep the image clear and avoid affecting the resection operation.

[0100] Please refer to the appendix Figure 10 , a method for using a gastrointestinal polyp resection device, including the following steps:

[0101] S1. Smoothly send the device into the patient's gastrointestinal tract through the towing rope 24 and monitor the progress of the device in real time with the monitoring probe 11;

[0102] After the device reaches the target position, the central hub 10 controls the lifting hatch 6 to descend through the electric push rod, preparing to enter the resection mode;

[0103] S3. After the jaws 8 extend and unfold, use the high-frequency electrotome 9 to resect the polyp. After the electrotome finishes, stop the operation. The jaws 8 retract and grasp the resected polyp;

[0104] The resected polyp is grabbed by the jaws 8 and recovered inside the upper shell 2. Multiple polyps are stored in a closed manner by area through the partition 7. The first rotating shaft 13 drives the gear 14 and the toothed ring 15 to rotate, causing the upper shell 2 to rotate self - clockwise to select a new cutting and storage area;

[0105] S5. After the operation, the central hub 10 drives the second rotating shaft 17, so that the second rotating shaft 17 drives the roller rod 18 to squeeze the delivery tube 22 and generate a vacuum suction force to suck the hemostatic gel from the second capsule 21;

[0106] S6. The hemostatic gel is sprayed onto the wound through the delivery tube 22 to ensure the hemostasis effect. If the pH value is greater than 6, the device releases an oxidant through the first capsule 20 for acid resistance.

[0107] Working principle: When polyp resection is required, the device is inserted into the patient's gastrointestinal tract through the towing rope 24. After monitoring by the monitoring probe 11 and finding that it has reached the designated position, the polyp resection operation begins. At this time, the central hub 10 controls the electric push rod to control the lifting hatch 6 to descend, and then controls the jaws 8 to extend and unfold. First, the high - frequency electrotome 9 is used to resect the polyp. After resection, the high - frequency electrotome 9 stops operating, and the jaws 8 begin to retract and grasp. At this time, the cut polyp is grabbed and then recovered inside the upper shell 2. Through the separation of the partition 7, multiple removed polyps can be placed in a closed manner in different areas. When operations in other position compartments are required, the first rotating shaft 13 can be driven so that it drives the toothed ring 15 to rotate through the gear 14. When the toothed ring 15 rotates, it drives the entire upper shell 2 to rotate through the rotating ring 4, so as to rotate self - clockwise without the device moving, and then select a new space for cutting and storing polyps for further polyp cutting operations. After the operation, for postoperative treatment, the central hub 10 can be used to drive the rotation of the second rotating shaft 17, so that the second rotating shaft 17 drives the roller rod 18, causing the roller rod 18 to intermittently squeeze the delivery tube 22, thereby generating a vacuum suction force to pump out the hemostatic gel in the second capsule 21. Finally, through the delivery of the delivery tube 22, it is sprayed onto the wound through the delivery head 23. When the pH value is greater than 6, the device releases an oxidant for acid resistance.

[0108] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

10. A method for using a gastrointestinal polyp resection device, which is a gastrointestinal polyp resection device according to any one of claims 1-9, characterized in that, It includes the following steps: S1. The device is smoothly sent into the patient's gastrointestinal tract through the towing rope (24), and the process of the device is monitored in real time with the help of the monitoring probe (11); S2. After the device reaches the target position, the central hub (10) controls the lifting hatch (6) to descend through the electric push rod to prepare to enter the resection mode; S3. When the jaw (8) extends and unfolds, the high-frequency electrotome (9) is used to resect the polyp, and the electrotome stops operating after completion. The jaw (8) retracts and grabs the resected polyp; S4. The resected polyp is grabbed by the jaw (8) and recovered inside the upper shell (2), and multiple polyps are stored in a closed manner by area through the partition (7). The rotating shaft one (13) drives the gear (14) and the toothed ring (15) to rotate, so that the upper shell (2) rotates itself to select a new cutting and storage area; S5. After the operation, the central hub (10) drives the rotating shaft two (17), so that the rotating shaft two (17) drives the roller rod (18) to squeeze the delivery tube (22) and generate a vacuum suction force to suck out the hemostatic gel from the capsule two (21); S6. The hemostatic gel is sprayed onto the wound through the delivery tube (22) to ensure the hemostatic effect. If the pH value is greater than 6, the device releases an oxidant through capsule one (20) for acid resistance.
