Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to a method for postoperative digital rectal stimulation. Background Technology

[0002] Surgical procedures, as a key means of treating various diseases in modern medicine, play an irreplaceable role in saving lives and improving quality of life. However, during surgical treatment, the patient's body is inevitably affected by a combination of factors, including anesthetic drugs, surgical trauma stress, and postoperative bed rest. Among these, postoperative gastrointestinal dysfunction, especially abdominal distension, is one of the most common and challenging complications in clinical practice. This functional disorder not only causes significant abdominal distension and discomfort, severely affecting the patient's subjective feelings and quality of rest, but more importantly, it directly delays the recovery process of normal gastrointestinal motility, thereby slowing down wound healing. In more severe cases, severe abdominal distension may trigger a series of chain pathophysiological reactions, including but not limited to respiratory restriction due to diaphragmatic elevation, inferior vena cava reflux obstruction due to increased intra-abdominal pressure, and even more dangerous intestinal paralysis and intestinal adhesions, increasing the patient's postoperative risks and recovery period.

[0003] In existing technologies, treatment typically involves using glycerin suppositories or applying traditional Chinese medicine hot compresses to the abdomen. However, after research, it was found that these methods still have the following problems: 1. Glycerin suppositories target the problem too "downstream," with their effects mainly limited to the anorectal region. They offer limited contribution to restoring the propulsive peristaltic capacity of the stomach, small intestine, and upper colon. While they can resolve the blockage at the "outlet," they cannot fundamentally drive the "upstream" motility system. Therefore, their therapeutic effect is often temporary and cannot systematically rebuild the motility rhythm of the entire digestive tract.

[0004] 2. Traditional Chinese medicine hot compresses lack precise control over key points. In particular, the stimulation intensity and specificity of the "anorectal reflex," a specific neural activity crucial for triggering the final defecation behavior, are insufficient, making it difficult to form an effective triggering signal. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a postoperative rectal digital stimulation method, which solves the problem of "low work efficiency" in the aforementioned background technologies.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a postoperative rectal digital stimulation method, comprising the following steps: Step 1: Targeted activation of the gastrocolic reflex, mainly by simulating physiological eating stimuli to remotely initiate mass movement of the colon; Step 2: After Step 1 is completed, a broad-spectrum enhancement of intestinal peristalsis is performed through a preset physiological response delay time. This is mainly achieved by using a combination of physical and chemical stimulation to enhance and maintain the intensity and duration of the intestinal peristaltic waves generated by the aforementioned steps. Step 3: After the broad-spectrum enhancement of the intestinal peristalsis function is completed, the pre-sensitization and emptying preparation of the rectal ampulla receptors are immediately performed. This mainly involves pre-treating the rectum using both chemical and physical methods to reduce fecal expulsion resistance and increase the sensitivity of rectal wall pressure receptors. Step 4: After the pre-sensitization and emptying preparation of the receptors in the rectal ampulla are completed, the precise mechanical triggering of the anorectal reflex is performed. This is mainly done by directly stimulating the key nerve reflexes that control defecation through standardized finger mechanical operation to complete the defecation action.

[0007] Preferably, the targeted activation of the gastrocolic reflex specifically includes: First, a standardized liquid nutrient bolus is prepared for the patient. The volume of the bolus is precisely limited to between 150 ml and 250 ml. The patient is then instructed to ingest the entire bolus at a uniform rate over 5 to 10 minutes. This creates effective volumetric and chemical stimulation in the stomach, triggering physiological propulsive peristaltic waves in the distal colon. The temperature of the bolus is controlled between 38 and 42 degrees Celsius. The bolus is composed of an isotonic or slightly hypertonic glucose electrolyte solution, with a glucose concentration of 5% to 10%, and contains physiological concentrations of sodium chloride and potassium chloride.

[0008] Preferably, the broad-spectrum enhancement of intestinal peristalsis specifically includes: (1) The heat-drug combined transdermal stimulation technology is used, and the stimulation source is a prefabricated combustible therapeutic body; (2) The operator holds a moxibustion device with the combustible therapeutic body fixed in hand and applies a suspended heat stimulation to a specific acupoint area on the abdomen with the burning end of the combustible therapeutic body. The specific acupoint area includes the Tianshu acupoint area located two inches to the side of the navel and the Zhongwan acupoint area located four inches above the navel on the anterior midline. (3) When applying stimulation, the vertical distance between the burning end of the combustible therapeutic body and the skin surface is dynamically adjusted to ensure that the vertical distance is maintained between 2 cm and 3 cm, and the skin surface temperature of the heated area is kept constant within the treatment window of 43 degrees Celsius to 45 degrees Celsius. (4) The moxibustion time for each specific acupoint area is set to 15 minutes, so as to comprehensively enhance the peristalsis of the stomach, small intestine and colon through the dual effects of heat energy and the pharmacologically active ingredients released by the combustion of the combustible therapeutic body.

[0009] Preferably, the combustible therapeutic body is made by mixing and pressing a variety of Chinese herbal powders with mugwort floss. The components of the Chinese herbal powders, by weight in grams, include: 50 grams of mugwort leaves, 10 grams of cinnamon, 10 grams of dried ginger, 5 grams of cloves, 5 grams of costus root, and 2 grams of borneol as a transdermal penetration enhancer.

[0010] Preferably, the process of ensuring that the skin surface temperature is kept constant within the treatment window of 43 to 45 degrees Celsius is achieved by using a non-contact infrared thermometer to monitor the skin temperature of the heated area in real time, and dynamically and finely adjusting the height of the moxibustion device based on the real-time monitored temperature value.

[0011] Preferably, the pre-sensitization and emptying preparation of the rectal ampulla receptor specifically involves: using a 20 ml hypertonic lubricant encapsulated in a disposable polyethylene container with a slender administration tube, the components of which, by volume fraction, include: 52.5% glycerol, 25% sorbitol, and the remainder purified water. With the patient in a left lateral decubitus position, the administration tube of the disposable container is slowly inserted into the patient's anus, and all 20 ml of liquid is injected into the rectal ampulla at once. After injection, the patient is asked to maintain the original supine position and retain the hypertonic lubricant in the rectum for 5 to 10 minutes to soften the stool and increase the volume of contents through hypertonic action, and to reduce the coefficient of friction of the rectal wall through lubrication.

[0012] Preferably, the precise mechanical triggering of the anorectal reflex specifically includes: (1) The operator wears double-layer sterile medical latex gloves coated with medical-grade water-soluble lubricant and slowly inserts his index finger into the rectal ampulla of the patient to a depth of 5 to 7 centimeters. (2) First, perform a preliminary exploration and clearing procedure. If a hard fecal mass is found, use the pad of your index finger to break it apart and remove it until the ampulla is clear. (3) After confirming that the ampulla is unobstructed, perform a standardized two-stage circular stimulation procedure; (4) After completing the two-stage circular stimulation procedure, completely withdraw the index finger and allow the patient to undergo a 2-minute resting period of nerve reflexes; (5) After the resting period of the nerve reflex is completed, the entire operation process from insertion and exploration to the two-stage stimulation procedure is repeated once, so that the precise mechanical triggering of the anorectal reflex includes two complete stimulation cycles.

[0013] Preferably, the first stage of the two-stage annular stimulation procedure is the rectal wall proprioceptor activation stage, and the specific operation of this stage is as follows: (31) The operator's index finger is inside the rectal ampulla, with its fingertip pressed tightly against the inner wall of the rectum; (32) Perform circular massage in a clockwise direction, wherein the rotation speed of the circular massage is controlled in a slow range of 10 to 15 revolutions per minute; The duration of this phase is precisely set to 60 seconds, aiming to fully activate the pressure receptors and tension receptors in the rectal wall.

[0014] Preferably, after completing the first stage, the second stage of the two-stage circular stimulation procedure is a targeted stimulation stage of the internal anal sphincter and puborectalis muscle complex. Specifically, the operator's index finger is slightly withdrawn from the ampulla, positioning its fingertip at the anatomical level where the upper edge of the internal anal sphincter and the puborectalis muscle ring are located. At this position, the index fingertip repeatedly stimulates the area with a short and forceful scraping motion from back to front and toward the pubic symphysis. The frequency of the scraping motion is 1 to 2 times per second. In addition, the duration of this stage is precisely set to 30 seconds, which mainly refers to the specific and high-intensity stimulation of the key afferent nerve fibers controlling the defecation reflex.

[0015] (III) Beneficial Effects This invention provides a method for postoperative digital rectal stimulation. It has the following beneficial effects: (1) When using this postoperative rectal digital stimulation method, it organically integrates multiple links such as gastrocolic reflex activation, whole intestinal peristalsis enhancement, rectal terminal presensitization and key nerve reflex precise triggering through four steps to construct a complete artificial intervention system. This system is used to simulate and repair the normal defecation physiological chain interrupted by surgical trauma. It has a high degree of systematicness, logic and synergy, which can fundamentally solve the problem of limited efficacy caused by fragmented intervention in existing technologies. This provides a rapid, effective and safe way to treat postoperative gastrointestinal dysfunction in clinical practice.

[0016] (2) When using this postoperative rectal digital stimulation method, key nodes are controlled through precise multi-stage design: in the gastrocolic reflex stage, the reflex arc is activated by a nutrient bolus with a specific formula, temperature and volume; in the intestinal enhancement stage, peristalsis is amplified by precise temperature control and acupoint-targeted thermo-pharmacy combined stimulation. Finally, through a standardized two-stage circular stimulation program, the "anorectal reflex" is precisely triggered, forming a strong and specific defecation signal, solving the problem that traditional methods are difficult to effectively trigger the terminal defecation reflex. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the method flow of the present invention. Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 This invention provides a method for digital stimulation of the posterior rectum, comprising four steps. First, targeted activation of the gastrocolic reflex serves as the physiological signal initiation stage of the entire process. Next, broad-spectrum enhancement of intestinal peristalsis amplifies and maintains the upstream activation signal. Then, pre-sensitization and emptying preparation of the rectal ampulla receptors are performed, serving as pre-treatment and clearance for the defecation terminal effectors. Finally, precise mechanical triggering of the anorectal-colonic reflex is executed, serving as the final trigger stage of the entire process. These four steps together constitute a complete, artificially constructed pathway for the restoration of motility and the triggering of defecation from the upper digestive tract to the anus and rectum.

[0020] Before formally initiating the entire procedure, a comprehensive baseline assessment of the patient's condition is conducted by qualified medical personnel to ensure the safety and appropriateness of the procedure. The primary step in the assessment is to rule out absolute contraindications such as mechanical intestinal obstruction, peritonitis, and intestinal perforation. Specific assessment methods include a systematic physical examination of the abdomen. The operator uses a standard medical stethoscope to auscultate bowel sounds in each of the four quadrants of the patient's abdomen—right upper quadrant, left upper quadrant, right lower quadrant, and left lower quadrant—for at least one minute. The frequency, pitch, and nature of bowel sounds per minute are recorded. A typical manifestation of postoperative gastrointestinal dysfunction is decreased or absent bowel sounds, i.e., less than 4 times per minute. Simultaneously, percussion is performed on the entire abdomen to determine if there is an enlargement of the tympanic area due to intestinal gas accumulation. Once it is confirmed that the patient has no signs of mechanical obstruction and that vital signs are stable, the intervention procedure described in this invention can begin.

[0021] The targeted activation of the gastrocolic reflex primarily utilizes the body's inherent physiological reflex arc to initiate mass movement of the distal colon in the most natural way. The carrier for this targeted activation is a liquid nutrient bolus. The total volume of the liquid nutrient bolus is set at 200 ml, sufficient to create effective mechanical expansion within the stomach, thereby activating stretch receptors in the stomach wall, but not enough to cause patient discomfort or increase the risk of aspiration. The temperature of the liquid nutrient bolus is precisely controlled at 40 degrees Celsius using a constant-temperature water bath. This temperature is close to the body's core temperature, avoiding the inhibitory effects of cold stimulation on the gastric mucosa and gastric smooth muscle. The specific formula for the liquid nutrient bolus is: dissolving 15 grams of medical-grade anhydrous glucose (forming a 7.5% microhypertonic solution), 0.7 grams of sodium chloride, and 0.3 grams of potassium chloride in 200 ml of sterile purified water, thus creating an isotonic or microhypertonic glucose electrolyte solution. During administration, the patient is required to ingest the entire liquid nutrient bolus over 5 to 10 minutes at a relatively uniform pace. The resulting increase in gastric volume and alteration of the gastric chemical environment transmit signals to the distal intestine via two parallel neurohumoral pathways: first, through the vagus-vagal reflex, the signal is directly transmitted to the colon; second, it stimulates G cells in the gastric antrum to secrete gastrointestinal hormones such as gastrin. These hormones, after entering the bloodstream, act on corresponding receptors on colonic smooth muscle cells. These two pathways work together to effectively stimulate several high-intensity, long-distance propulsive peristaltic waves in the transverse colon, descending colon, and even the sigmoid colon—a physiologically known as "mass movement"—providing the initial driving force for the subsequent downward transport of intestinal contents.

[0022] After the targeted stimulation of the gastrocolic reflex is completed, a preset physiological response delay time of 15 to 20 minutes needs to be set. This time is scientifically set based on the physiological conduction velocity of gastrointestinal neurohumoral regulation and the response time of colonic motility, ensuring that the physiological effects stimulated by the targeted stimulation of the gastrocolic reflex can be fully established and transmitted to the middle and lower intestines. After this delay time, the second stage of the process is immediately initiated, which is the broad-spectrum enhancement of intestinal peristalsis. The broad-spectrum enhancement of intestinal peristalsis mainly involves a powerful and broad-spectrum amplification and maintenance of the intestinal peristalsis initially initiated by the targeted stimulation of the gastrocolic reflex, ensuring that the intensity and duration of the peristaltic waves are sufficient to propel intestinal contents to the rectum, using a combined thermo-drug transdermal stimulation technique.

[0023] The combined heat-drug transdermal stimulation technology uses a pre-fabricated cylindrical combustible therapeutic body with specific specifications and components. The preparation process of the therapeutic body is as follows: First, various traditional Chinese medicinal herbs with the effects of warming and unblocking meridians and promoting blood circulation are selected, dried to a moisture content of less than 5%, and then pulverized into a fine powder that can pass through a 100-mesh sieve. The mass ratio of each component is as follows: 50 grams of aged mugwort leaves, which is the main heat-generating and drug carrier; 10 grams of cinnamon and 10 grams of dried ginger, both of which are pungent and hot, synergistically enhancing the warming effect and exerting their own pharmacological activity; 5 grams of cloves and 5 grams of costus root, both of which have the effects of promoting qi circulation, relieving pain, and promoting the secretion of digestive juices; and 2 grams of natural borneol, whose volatile components can significantly increase the permeability of the stratum corneum of the skin. The powder is mixed evenly with a small amount of refined honey water (Baumé degree 38-40) as a binder, and then pressed into a homogeneous cylinder with a diameter of 1.8 cm and a length of 20 cm using a mold. The cylinder is then placed in a ventilated and dry place to air dry until it has a solid structure and is stable to burn.

[0024] During this procedure, one end of the aforementioned combustible therapeutic object is ignited. Once it exhibits uniform, flameless combustion, it is secured within a specially designed moxibustion device. This device is made of high-temperature resistant brass or stainless steel and includes a support for holding the therapeutic object, a metal mesh cover to prevent ash from falling, and a heat-insulating wooden or polymer handle. The operator holds the device and applies suspended thermal stimulation to two specific treatment areas on the patient's abdomen. The first treatment area is the bilateral Tianshu acupoints, anatomically located two inches lateral to the umbilicus. The second treatment area is the Zhongwan acupoint, anatomically located on the anterior midline, four inches above the umbilicus. During stimulation, the vertical distance between the burning end of the therapeutic object and the skin surface is dynamically controlled between 2 and 3 centimeters. Additionally, the operator uses a high-precision non-contact infrared thermometer to continuously monitor the skin surface temperature of the heated area, fine-tuning the height of the moxibustion device to ensure the temperature is consistently maintained within a narrow therapeutic window of 43 to 45 degrees Celsius. The moxibustion time for each treatment area was precisely set to 15 minutes. During this process, the heat energy generated by the burning of the treatment body, along with the pharmacologically active volatile oil components released and deposited on the skin surface along with the hot airflow, are synergistically absorbed through the heat-dilated pores and the stratum corneum enhanced by borneol, directly stimulating the intestinal smooth muscle. The combined heat-drug transdermal stimulation technology constitutes a broad-spectrum peristalsis enhancement signal, ensuring that the upstream dynamics can be effectively amplified and transmitted downstream.

[0025] After broad-spectrum enhancement of intestinal peristalsis, pre-sensitization and emptying preparation of the rectal ampulla receptors are performed, specifically including softening the stool, lubricating the intestine, and pre-activating the receptors in the rectal wall. This is administered via a single rectal dose. The formulation used is a lubricating liquid with high osmotic pressure. The formulation is pre-packaged in a single-use container made of medical-grade low-density polyethylene through blow molding. This container is typically designed with a compressible corrugated bottle body and a slender, smooth applicator with a rounded tip, with a total volume of 20 ml.

[0026] The 20 ml lubricant consists of: 52.5% medical-grade glycerin, 25% 70% sorbitol solution, and the remainder is injection-grade purified water. These components are mixed thoroughly in a clean environment to obtain a clear, viscous liquid. Specifically, the high concentration of glycerin and sorbitol creates a strong hypertonic environment. When injected into the rectum, it actively draws water from the submucosal tissue of the rectal wall into the intestinal lumen through the osmotic pressure gradient, effectively softening any hardened feces that may be lodged in the rectal ampulla and increasing the total volume and fluidity of the intestinal contents. This increase in volume itself provides a mild, continuous stretching stimulation to the rectal wall, presensitizing the rectal pressure receptors. Simultaneously, glycerin is an excellent lubricant, forming a smooth liquid film on the rectal mucosa and fecal surface, reducing both static and dynamic friction coefficients and removing physical obstacles for subsequent fecal expulsion.

[0027] In addition, instruct the patient to assume a standard left lateral decubitus position with both knees bent towards the chest. This anatomical alignment of the rectal ampulla is more conducive to the injection and retention of the medication. After donning sterile gloves, the operator applies a small amount of lubricant to the tip of the disposable container's administration tube and gently and completely inserts it into the patient's anus until the tube reaches the root. Then, squeeze the entire 20 ml of liquid from the container into the rectum at once. After injection, remove the administration tube and instruct the patient to remain in the supine position while tightening the gluteal muscles to prevent premature leakage of the liquid. The patient should retain this liquid in the rectum for at least 5 to 10 minutes. This retention time is necessary to ensure the full effectiveness of the hyperosmolar effect and lubrication.

[0028] Once the presensitization of the rectal ampulla receptors and the fluid retention time for emptying preparation have reached the preset value, the precise mechanical triggering of the anorectal reflex is performed. Specifically, the first step is pre-operative preparation. The operator must wear double-layered sterile medical latex gloves to ensure the highest hygiene standards. A layer of medical-grade water-soluble lubricant (such as sterile paraffin oil or a special lubricating gel) approximately 1 mm thick is evenly applied to the surface of the right index finger used for the procedure to reduce friction and discomfort during the operation.

[0029] Next, the operator uses an extremely gentle rotating motion, positioning the lubricated tip of their index finger at the patient's anus, and slowly inserts it in sync with the patient's breathing, passing through the anal canal for about 3-4 centimeters, into the spacious rectal ampulla. The insertion depth is precisely controlled so that the base of the index finger (metacarpophalangeal joint) is completely submerged in the anal margin, typically corresponding to a depth of about 5-7 centimeters, ensuring the operating area is centered within the rectal ampulla. During this process, the operator's fingertip needs to sense the condition within the ampulla. If a hard, large, and immovable fecal mass is detected, a clearing procedure must be performed first. This procedure requires the operator to use the fingertip to break the impacted fecal mass into smaller pieces and remove them one by one until the rectal ampulla feels basically open, with no large physical obstructions remaining.

[0030] After confirming the patency of the rectal ampulla, the standardized two-stage circular stimulation procedure officially begins. The first stage is defined as "activation of rectal wall proprioceptors." The operator places their index finger inside the rectal ampulla, ensuring the fingertip is in close contact with the rectal wall with a large contact area. Then, using the wrist as an axis, the index finger is driven to perform a complete 360-degree circular massage in a clockwise direction within the ampulla. The angular velocity of this circular massage is strictly controlled within a slow range of 10 to 15 revolutions per minute, mainly to apply continuous and sufficient stretch stimulation to the pressure receptors and tension receptors in the intestinal wall, simulating the feeling of fecal fullness, thereby generating a large number of afferent nerve impulses to report the "rectum is full" signal to the spinal defecation center. The operation time is 60 seconds.

[0031] The second stage then begins, defined as targeted stimulation of the internal anal sphincter and puborectalis muscle complex. After 60 seconds of circular massage, the operator's index finger is withdrawn slightly outward from the ampulla of Vater, about 2-3 centimeters, so that the fingertip's positioning point moves to the key functional area anatomically known as the "anorectal ring," formed by the upper edge of the internal anal sphincter and the posterior puborectalis muscle ring. The operator then changes their movement pattern. The pad of the index finger repeatedly stimulates this area with a short, forceful "scraping" or "pressing" motion from back to front, i.e., towards the patient's pubic symphysis. The frequency is set to 1 to 2 times per second. The duration of this stage is precisely set to 30 seconds.

[0032] After completing the full stimulation procedure, which consists of two phases, the operator completely and smoothly withdraws the index finger from the anus. A two-minute "nerve reflex resting period" is then initiated. This resting period is designed to provide the nervous system with a window to process the large influx of incoming signals and organize coordinated outgoing motor commands. It also avoids nerve ending fatigue or adaptation that could result from continuous stimulation.

[0033] After the 2-minute rest period, the operator needs to repeat the entire procedure from "preparatory exploration" to "two-stage stimulation program" once. In other words, the precise mechanical triggering of the anorectal reflex involves two identical stimulation cycles consisting of "exploration - circular massage - targeted stimulation - rest," thus forming the final, decisive, and highly engineered artificial trigger signal for the anorectal reflex arc. Example

[0034] A 68-year-old male patient underwent laparoscopic sigmoid colectomy for colon cancer. On the third postoperative day, the patient complained of severe abdominal distension, with a distended abdomen and an abdominal circumference of 102 cm measured at the umbilicus. No bowel sounds were heard during abdominal auscultation for two minutes. The patient had not passed gas or stool since the surgery. The visual analog scale (VAS) was used to assess the degree of subjective discomfort due to abdominal distension, with the patient scoring 9 points (0 representing no discomfort, 10 representing the most severe discomfort). After ruling out mechanical obstruction, the method of this invention was applied to the patient, with the specific steps and time points as follows: Step 1: At the start time of the intervention process (denoted as T0), prepare 200 ml of 7.5% glucose electrolyte solution with the temperature precisely controlled at 40℃ for the patient (the formula is 200 ml of sterile purified water containing 100 g of medical-grade anhydrous glucose, 0.7 g of sodium chloride, and 0.3 g of potassium chloride). Instruct the patient to drink the solution at a steady rate and finish drinking all the liquid by T8 minutes to complete the gastrocolic reflex targeted stimulation operation.

[0035] Step Two: Set a 15-minute physiological response delay time (i.e., start timing from T8 minutes and delay to T23 minutes) to ensure that the mass movement effect triggered by the gastrocolic reflex is fully transmitted to the middle and lower intestines. Immediately at T23 minutes, initiate the broad-spectrum enhancement operation of intestinal peristalsis: Use the cylindrical combustible therapeutic body prepared with the aforementioned formula (50g of aged mugwort leaves, 10g of cinnamon, 10g of dried ginger, 5g of cloves, 5g of costus root, and 2g of natural borneol, pressed into a cylinder with a diameter of 1.8cm and a length of 20cm), ignite one end of the therapeutic body until it is in a state of uniform combustion without open flame, fix it in a specially made suspension moxibustion device, and sequentially apply suspension heat stimulation to the patient's Zhongwan, left Tianshu, and right Tianshu acupoint areas. The moxibustion time for each acupoint area is precisely controlled to the minute. The moxibustion period for Zhongwan acupoint is T23-T38 minutes, the moxibustion period for left Tianshu acupoint is T38-T53 minutes, and the moxibustion period for right Tianshu acupoint is T53-T68 minutes. During the moxibustion process, the skin temperature is monitored in real time by a high-precision non-contact infrared thermometer, and the temperature of the heated area is always kept stable at 44±1℃. At T68 minutes, the broad-spectrum enhancement of intestinal peristalsis is completed.

[0036] Step 3: At T68 minutes after the completion of Step 2, immediately instruct the patient to adjust to a standard left lateral decubitus position (both knees bent towards the chest). The operator, wearing sterile gloves, gently injects 20 ml of pre-prepared hypertonic lubricant (volume percentage: 52.5% medical-grade glycerin, 25% 70% sorbitol solution, and the remainder being injectable purified water) into the patient's rectum through a disposable injection tube. After injection, instruct the patient to maintain the left lateral decubitus position and tighten the gluteal muscles to ensure that the lubricant is fully retained in the rectum. At T78 minutes, the patient has completed 10 minutes of lubricant retention, and Step 3 is complete.

[0037] Step Four: First Stimulation Cycle (T78-T89 minutes): At T78 minutes after the end of Step Three, the operator immediately puts on double-layered sterile medical latex gloves, evenly applies a 1 mm thick layer of medical-grade water-soluble lubricant to the surface of the right index finger cot, and gently rotates the index finger in rhythm with the patient's breathing to insert it into the rectal ampulla (insertion depth until the metacarpophalangeal joint is completely submerged in the anal margin, about 5-7 cm). After confirming that there is no large fecal impaction obstructing the rectal ampulla, the first stage of "rectal wall proprioceptor activation" begins at T79 minutes: at a rate of 10-15 rotations per minute. Massage the rectal wall in a clockwise circular motion at an angular velocity until T80 minutes (60 seconds); then, starting from T80 minutes, perform the second stage of "targeted stimulation of the internal anal sphincter and puborectalis muscle complex": withdraw the index finger 2-3 cm outward to the anorectal ring area, and apply short, sharp pressure stimulation from back to front at a frequency of 1-2 times per second until T80 minutes 30 seconds (30 seconds); after the stimulation, smoothly withdraw the index finger to enter the "nerve reflex resting period" (T80 minutes 30 seconds - T82 minutes 30 seconds, 2 minutes), and the first stimulation cycle ends.

[0038] Step 5: Second Stimulation Cycle (T91-T102 minutes): At T82 minutes and 30 seconds after the end of the rest period of the first stimulation cycle, repeat the above "exploration-circular massage-targeted stimulation-rest" process. The second stage of targeted stimulation ends at T93 minutes and 30 seconds, and the rest period is from T93 minutes and 30 seconds to T95 minutes and 30 seconds. The second stimulation cycle is completed at T95 minutes and 30 seconds, and all operations in step 4 are completed.

[0039] Step Six: During the resting period of the second stimulation cycle (approximately T95 minutes and 30 seconds, about 95 minutes from the start of the entire procedure), the patient reported a strong urge to defecate, followed by the successful expulsion of a large amount of gas and approximately 300 grams of soft stool onto the bedpan. One hour after the completion of the entire intervention (T165 minutes and 30 seconds), the patient was reassessed: abdominal circumference decreased to 93 cm, active bowel sounds were audible on abdominal auscultation (approximately 7 times per minute), and the patient's VAS score decreased to 2 points.

[0040] Comparative example: Another patient was selected who was highly similar to the patient in the example in terms of age, gender, surgical procedure, and postoperative condition (postoperative day 3, abdominal circumference 101 cm, no bowel sounds, no flatus or defecation, VAS score 9). Routine clinical interventions were implemented. The specific procedures were as follows: Step 1: At the start of the intervention process (denoted as T0), prepare one standard clinical enema (main ingredient is 50% glycerin, total volume 20 ml), and instruct the patient to adjust to the left lateral decubitus position (both knees bent towards the chest), simulating the position for rectal administration in the example, to ensure consistency of operating conditions.

[0041] Step 2: Medication Injection (T0-T1 minutes): The operator wears sterile gloves, cuts open the tip of the enema (or removes the sealing cap), applies a small amount of medical lubricant to the open end to reduce insertion resistance, and then gently inserts the thin end of the enema tube into the patient's anus (insertion depth of about 3-4 cm, similar to the insertion depth of the medication tube in the example). Slowly squeeze the bulb of the enema until T1 minutes, when all 20 ml of medication is injected into the rectum. After injection, smoothly remove the thin end of the enema tube and instruct the patient to maintain a left lateral decubitus position and tighten the buttock muscles to prevent the medication from flowing out prematurely.

[0042] Step 3: Medication retention (T1-T16 minutes): The patient is asked to maintain a left lateral decubitus position to ensure that the enema is fully retained in the rectum; at T16 minutes, the patient has completed the retention of the medication (which is in line with the recommended retention time of 10-15 minutes for regular enema use) and can get up on their own to try to defecate.

[0043] Step 4: Defecation status (T16-T20 minutes): During the patient's attempt to defecate, only a small amount of gas and about 20 ml of clear liquid were expelled, and no formed stool was expelled. The patient reported that the urge to defecate was mild and brief, and the abdominal distension was not significantly relieved after defecation.

[0044] Step 5: Review Results (T76 minutes): One hour after the first intervention (i.e., T76 minutes), the patient was reassessed: the abdominal circumference was measured at 100 cm, only 1 cm less than before the intervention; no clear bowel sounds were heard during abdominal auscultation for 2 minutes; the degree of abdominal distension and discomfort was assessed using the VAS score, which was 8 points, only 1 point less than before the intervention. The overall gastrointestinal function recovery effect was significantly weaker than the intervention method in the example.

[0045] To illustrate the above practices more clearly, please see the table below for details: Evaluation indicators Example (Method of the Invention) Comparative example (conventional method) First time passing gas / bowel movement During the operation (approximately 95 minutes) Failure to defecate effectively Changes in abdominal circumference (1 hour after the procedure) Reduced by 9 cm (from 102 cm to 93 cm) Reduce by 1 cm (from 101 cm to 100 cm) Bowel sound recovery status (1 hour after procedure) Restored to 7 times / minute (active) Still not recovered (0 times / minute) VAS score change (1 hour after operation) Reduce by 7 points (from 9 points to 2 points). Decrease by 1 point (from 9 to 8). Stool volume Large amount of gas and about 300g of soft stool Small amounts of gas and liquid As can be seen from the above embodiments, comparative examples, and data comparisons, the present invention is significantly superior to traditional, single intervention methods.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Claims

1. A method for postoperative rectal digital stimulation, characterized in that, Includes the following steps: Step 1: Targeted activation of the gastrocolic reflex, mainly by simulating physiological eating stimuli to remotely initiate mass movement of the colon; Step 2: After Step 1 is completed, a broad-spectrum enhancement of intestinal peristalsis is performed through a preset physiological response delay time. This is mainly achieved by using a combination of physical and chemical stimulation to enhance and maintain the intensity and duration of the intestinal peristaltic waves generated by the aforementioned steps. Step 3: After the broad-spectrum enhancement of the intestinal peristalsis function is completed, the pre-sensitization and emptying preparation of the rectal ampulla receptors are immediately performed. This mainly involves pre-treating the rectum using both chemical and physical methods to reduce fecal expulsion resistance and increase the sensitivity of rectal wall pressure receptors. Step 4: After the pre-sensitization and emptying preparation of the receptors in the rectal ampulla are completed, the precise mechanical triggering of the anorectal reflex is performed. This is mainly done by directly stimulating the key nerve reflexes that control defecation through standardized finger mechanical operation to complete the defecation action.

2. The method for postoperative rectal digital stimulation according to claim 1, characterized in that: The targeted activation of the gastrocolic reflex specifically includes: First, a standardized liquid nutrient bolus is prepared for the patient. The volume of the bolus is precisely limited to between 150 ml and 250 ml. The patient is then instructed to ingest the entire bolus at a uniform rate over 5 to 10 minutes. This creates effective volumetric and chemical stimulation in the stomach, triggering physiological propulsive peristaltic waves in the distal colon. The temperature of the bolus is controlled between 38 and 42 degrees Celsius. The bolus is composed of an isotonic or slightly hypertonic glucose electrolyte solution, with a glucose concentration of 5% to 10%, and contains physiological concentrations of sodium chloride and potassium chloride.
