Description

Technical Field

[0001] This utility model relates to the field of minimally invasive surgical auxiliary positioning technology, and in particular to a wirelessly controlled gastrointestinal positioning device. Background Technology

[0002] The statements in this section are merely to provide background information related to the disclosure of this utility model and do not necessarily constitute prior art.

[0003] Precise localization of intestinal lesions during laparoscopic surgery relies heavily on preoperative imaging. Titanium clip localization is prone to deviation due to intestinal displacement during the procedure. In laparoscopic colorectal surgery, surgeons rely on instruments and lack direct tactile feedback, often depending on visual feedback to determine tumor location. For colorectal tumors not involving the serosa or with small diameters, repeated intraoperative exploration and localization are necessary, sometimes requiring manual assessment, leading to prolonged surgery time and poor localization accuracy. Staining and labeling methods (such as indocyanine green, methylene blue, and nano-carbon) are also used, with nano-carbon often used for endoscopic carbon injection localization. However, intraintestinal injection is complex, has a short duration of action, and is prone to diffusion and absorption by tissues, causing significant side effects. Therefore, intraoperative re-endoscopic or other imaging examinations are still necessary in clinical practice. These examinations and the equipment used require specialized personnel and equipment. Operating rooms often lack all the necessary imaging equipment, presenting both technical and equipment challenges. Therefore, assistance from endoscopists is frequently required for intraoperative lesion localization. Due to the movement of endoscopic equipment, it takes a long time to gather the endoscopic operation team, resulting in long waiting times during the operation and sometimes difficulty in obtaining assistance from endoscopists. This causes inconvenience to the operation, prolongs the anesthesia time, increases costs, adds surgical steps, makes the operation cumbersome, increases surgical costs, and increases the time cost of cross-departmental coordination. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a solution to the problem of inaccurate clinical positioning. It is simple to operate, optimizes the clinical examination and surgical procedures, eliminates the need for intraoperative endoscopy, reduces procedures, and lowers intraoperative costs. This can be extended to innovatively modify all surgical methods requiring positioning during laparoscopic surgery. During initial diagnosis, a wirelessly controlled positioning system can be placed into the lesion site using forceps to achieve fixation. It eliminates the need for interdepartmental consultations, external magnetic control devices, physical fixation, and inflation, thus preventing intestinal perforation, having no toxic side effects, simplifying the surgical procedure, and reducing surgical costs. This is a digestive tract wirelessly controlled intestinal positioning device and method.

[0005] The technical solution adopted in this utility model is: a wirelessly controlled gastrointestinal positioning device, the positioning device comprising: An intestinal marking module, placed on the inner wall of the intestine, includes a light source, a miniature receiver, and a receiver PCB integrated board, a housing for housing the light source, the miniature receiver, and the receiver PCB integrated board, and a suspension mechanism connected to the housing; and an external remote control module, which has a switch button for controlling the on / off state of the light source and a wireless transmission module to turn on the light source to illuminate the lesion location.

[0006] In this technical solution, the intestinal marking module also includes a housing for placing a light source, a miniature receiver, and a receiver PCB integrated board, as well as a suspension mechanism and a claw attached to the housing, the claw clamping the intestinal wall.

[0007] In this technical solution, the intestinal marking module also has a power supply unit, which provides power to the light source, the miniature receiver, and the receiver PCB integrated board.

[0008] In this technical solution, the external remote control module also includes a second power supply unit, which is connected to the switch button, the transmission indicator light, and the wireless transmission module for power supply.

[0009] In this technical solution, the external remote control module also has: An external body; and a sliding cover that slides on the external body to cover or expose a switch button arranged on the external body.

[0010] In this technical solution, the outer shell is a medical-grade transparent polymer shell with a diameter ≤12mm.

[0011] In this technical solution, the wireless transmission module is a PCB transmission integrated board with encoding and transmission functions. It can not only transmit wireless switch signals to a miniature receiver, but also has an independent encoding function. This allows it to avoid interference from similar signals when used in the same scenario with multiple wireless intestinal positioning devices for the digestive tract, thus ensuring its practical safety and reliability.

[0012] In this technical solution, the light source is a high-penetration LED cold light source, and the power supply unit one and power supply unit two are button batteries.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Wireless intestinal localization eliminates the need for interdepartmental consultations and cross-departmental collaboration, resulting in lower resource consumption and learning costs. Unlike preoperative titanium clip positioning, which requires titanium clips and abdominal X-rays / CT scans and is moderately expensive, or intraoperative colonoscopy positioning, which requires colonoscopes, gas, clamping devices, and cross-departmental collaboration and is expensive, or preoperative colonoscopy staining positioning, which requires staining consumables, injection needles, and colonoscope equipment and is expensive, wireless intestinal positioning eliminates the need for consultations with radiology and intestinal endoscopy departments during surgery. 2. No external magnetic control equipment required, accurate positioning: No external magnetic device is needed to strongly activate the internal magnetic capsule; it can be controlled with just a remote control. It allows for real-time visualization of the lesion location, precise positioning, and simple and convenient operation. 3. Physical fixation, no need for inflation, and will not cause intestinal perforation: Endoscopic procedures during surgery require a high level of skill from the surgical team. Currently, intestinal endoscopy during surgery requires insufflation. Even after the endoscope is removed, there is residual gas in the intestine. At this time, the laparoscope is continuously inflated with an insufflation machine. Due to the gas pressure difference, there is a risk of intestinal perforation. 4. No toxic side effects: It has the disadvantages of obvious staining leakage and excessively large staining area that affects the operation field. It also does not require the use of contrast agents or staining agents, which can significantly reduce surgical side effects. Staining agents have certain side effects. 5. Simplified surgical procedure, with excellent applicability: This invention reduces the number of examinations, eliminates the need for intraoperative imaging and endoscopy, and lowers surgical costs. For grassroots hospitals nationwide, operating rooms often lack dedicated intestinal endoscopy equipment. This invention only requires placement during colonoscopy examinations in the endoscopy department and does not need to be moved during surgery, thus simplifying the surgical procedure for doctors in grassroots hospitals. In summary, the entire resection surgery can be performed in the operating room without needing to move surgical equipment or the patient due to positioning issues, simplifying the surgical process. 6. Simplify procedures and reduce surgical costs: This procedure overcomes the current dual challenges of technology and equipment, which often require the assistance of endoscopic specialists for intraoperative lesion localization. The need to move endoscopic equipment and assemble the endoscopic team takes a long time, resulting in extended waiting times during the procedure and sometimes difficulty in obtaining assistance from endoscopists, causing inconvenience, prolonging anesthesia time, and increasing costs. The overall cost is lower than endoscopic examination (disposable, no risk of infection); and it offers excellent flexibility with real-time dynamic response via an external remote control module. 7. Simple to use and operate, no special training required: Specialized radiology personnel are not required. Colonoscopy and staining injection require specialized training, and many doctors need to learn them. This utility model's wireless control intestinal positioning device allows for clamping operations that almost every surgeon can perform, requiring no specialized training. 8. Wireless control for intestinal positioning, direct light source for lesion location: positioning accuracy can be accurate to ±1cm (direct light transmission), ensuring accurate positioning.

Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the combination or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, in the description of the embodiments of this utility model, the positional relationships of devices such as "upper," "lower," "front," "rear," "left," and "right" in all figures are based on... Figure 1 As the standard.

[0017] like Figure 1 As shown, a wirelessly controlled gastrointestinal positioning device includes an intestinal marking module 10 and an external remote control module 20. Among them, such as Figure 2 , Figure 3 and Figure 4 As shown, the intestinal marking module 10 is placed on the inner wall of the intestine and includes a light source 11, a micro receiver 12 and a receiving end PCB integrated board 13. It also includes a housing 14 for placing the light source 11, the micro receiver 12 and the receiving end PCB integrated board 13, and a suspension mechanism 15 connected to the housing 14. The suspension mechanism 15 is used to connect the entire intestinal marking module 10 to the lesion location in the digestive tract before surgery. The external remote control module 20 includes a switch button 21 for controlling the on / off state of the light source 11 and a wireless transmission module 23, so as to turn on the light source 11 to illuminate the lesion location.

[0018] The working process of the wirelessly controlled intestinal positioning device of this invention is as follows: 1. When a patient undergoes their first endoscopy and lesions such as early rectal cancer are found under endoscopy, in order to determine the location of the lesion, the doctor uses a colonoscope to clamp the intestinal marker module 10 at the proximal position of the lesion, and then fixes the intestinal marker module 10 to the lesion location using a harmonic clamp.

[0019] 2. During the operation, the surgeon triggers the switch button 21 before / during the operation via the external remote control module 20, sends a wireless command to activate the intestinal marker module 10 to locate the lesion, the light source 11 illuminates the intestinal wall, and a visible light spot is transmitted under the laparoscope to determine the location of the lesion. The surgeon determines the location of the lesion based on the location of the light spot, completes the operation, and retrieves the lesion tissue along with the device.

[0020] In at least one embodiment, such as Figure 4 As shown, the intestinal marking module 10 also includes a housing 14 for housing the light source 11, the miniature receiver 12, and the receiving end PCB integrated board 13, as well as a suspension mechanism 15 and a gripper 16 connected to the housing 14. The gripper 16 clamps the intestinal wall, thereby fixing the entire intestinal marking module 10 at the lesion location within the intestine for easy observation during surgery. In specific implementation, the gripper 16 adopts a flexible and adjustable structure, which can safely and reliably clamp the intestinal wall, allowing it to stably anchor the entire intestinal marking module 10 to the target lesion area without damaging the tissue. This fixation mechanism ensures that the marking module does not shift during subsequent surgery, thus providing clear and accurate visual and signal references for surgical positioning and real-time observation.

[0021] In at least one embodiment, such as Figure 4As shown, the intestinal marking module 10 also has a power supply unit 17, which provides power to the light source 11, the miniature receiver 12, and the receiving end PCB integrated board 13. The purpose of this design is twofold: firstly, to enable the intestinal marking module 10 to directly mark the location of lesions; and secondly, to directly illuminate the lesion location by turning on the light source 11 when needed during surgery, thus achieving lesion localization. In specific implementation, the miniature receiver 12 is mainly used to receive external signals. After receiving the external signal, it transmits the signal to the light source 11 (LED) and the power supply module on the receiving end PCB integrated board 13 to control the on / off state of the light source 11 (LED). After unpacking, pressing the switch button 21 on the wireless transmitter module 23 inside the external remote control module 20 connects it to the power supply, at which point the miniature receiver 12 enters standby mode.

[0022] Its miniaturized, high-capacity design provides a continuous and stable power supply to the internal light source 11, miniature receiver 12, and receiver PCB integrated board 13. Through this self-capacitive power supply design, the intestinal marking module 10 achieves two core functions: first, after placement, it can reliably operate at the lesion site for a long time, achieving a clear and lasting marking effect; second, during surgery, the light source 11 can be activated immediately as needed to directly illuminate the target area, assisting doctors in quickly and accurately identifying the lesion boundary and morphology in complex intracavitary environments, thereby significantly improving the intuitiveness of surgical positioning and operational efficiency.

[0023] In at least one embodiment, the external remote control module 20 further includes a second power supply unit 25, which supplies power to the switch button 21, the transmitter indicator light 22, and the wireless transmitter module 23, thereby providing sufficient power to the external remote control module 20. This embodiment, through the built-in second power supply unit 25 and the corresponding power management circuit, ensures stable voltage output of the external remote control module during operation, thus guaranteeing reliable wireless signal transmission and clear visibility of status indicators, providing users with intuitive and reliable human-machine interaction and remote control capabilities.

[0024] In at least one embodiment, such as Figure 5 As shown, the external remote control module 20 also has an external body 24, which typically supports the base plate and the remote control housing, thus serving as the main structure of the entire external remote control module; the external remote control module 20 also has a sliding cover 25, which slides on the external body 24 to cover or expose the switch button 21 arranged on the external body 24, so as to protect the switch button 21 arranged therein and ensure that it has good durability.

[0025] In at least one embodiment, the outer shell 14 is a medical-grade transparent polymer shell with a diameter ≤12mm, which can be safely placed inside the body and can detach from the body after being inside for a period of time, so as to assist the wireless control intestinal positioning device in the digestive tract to perform better positioning and ensure that it has good safety performance inside the body.

[0026] In at least one embodiment, the wireless transmission module 23 is a PCB transmission integrated board with encoding and transmission functions. It can not only transmit wireless switch signals to the miniature receiver 12, but also has an independent encoding function, so that when multiple digestive tract wireless control intestinal positioning devices are used in the same scenario, interference of the same type of signals is avoided, ensuring its practical safety and reliability.

[0027] In at least one embodiment, the light source 11 is a high-penetration LED cold light source with a specially optimized emission spectrum, possessing excellent tissue penetration capabilities. This effectively overcomes the absorption and scattering effects of the intestinal environment on light, ensuring sufficient and uniform illumination in the digestive tract. Simultaneously, its strong penetrability allows external surgical personnel to accurately locate lesions within the intestine. In specific implementation, power supply unit 17 and power supply unit 25 are button batteries, providing power to the intestinal marking module 10 and the external remote control module 20. Common batteries power both the intestinal marking module 10 and the external remote control module 20. This type of battery features high energy density, small size, stable discharge, and good safety, making it ideal for the long-term, low-power supply needs of in-vivo medical devices. The button battery provides reliable power for the light source, sensing, and circuit systems of the intestinal marking module 10, as well as the signal transmission, status indication, and control functions of the external remote control module 20. It can support and is an excellent power supply solution for portable and implantable medical electronic devices.

[0028] like Figure 6 As shown, a wireless control method for locating the gastrointestinal tract includes at least: placing the intestinal marker module 10 inside the digestive tract, clamping it at the proximal position of the lesion with the assistance of a colonoscope, fixing the intestinal marker module 10 to the lesion position through a suspension mechanism 15; and controlling the light source inside the intestinal marker module 10 to be turned on during surgery through an external remote control module 20, so as to locate the specific lesion position with the light source.

[0029] In the specific implementation process, the patient undergoes an initial endoscopic examination, which reveals early-stage rectal cancer. The lesion's location is determined, and with the aid of colonoscopy, the intestinal marker module 10 is clamped proximal to the lesion. Subsequently, a harmonic clamp is used to fix the intestinal marker module 10 to the lesion location. Based on clinical assessment, laparoscopic surgery is performed as soon as possible. Preoperative / intraoperative endoscopic examinations or other imaging examinations are no longer needed to locate the lesion. The doctor only needs to activate the positioning device via a remote control module 20, observe the light emanating from the placement site, locate the lesion under laparoscopy, and precisely remove the target intestinal segment. The positioning device can be removed along with the removed target intestinal segment. If not removed, it will naturally detach within one to two weeks and be automatically expelled with feces, fulfilling its purpose.

[0030] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
