With the increasing popularity of health examinations and gastroenteroscopy technology, endoscopic polyp treatment has become a routine diagnosis and treatment method in many medical institutions. After polyp treatment, in order to ensure the hemostasis effect of the wound, the endoscopist will carefully select the appropriate wound hemostatic clip according to the size and depth of the wound. Next, let us walk into the magical world of hemostatic clips and explore their mysteries.
Exploring the secrets of "hemostatic clips"
Hemostatic clips, a consumable that plays a key role in local wound hemostasis, consist of two parts: the clip part and the tail part. Its working principle is to achieve the purpose of hemostasis by tightly clamping blood vessels and surrounding tissues through mechanical closure, which is similar to the method of surgical vascular suturing or ligation, and will not cause coagulation, degeneration or necrosis of mucosal tissue. In addition, hemostatic clips are also favored for their non-toxicity, light weight, high strength and good biocompatibility. They are widely used in various endoscopic closed operations such as polypectomy, endoscopic submucosal dissection (ESD), hemostasis, and auxiliary positioning and other medical scenarios. After polypectomy or ESD, in order to prevent complications such as delayed bleeding and perforation, endoscopists will use titanium clips to clamp the wound according to the intraoperative situation.

Wide application of metal titanium clips in clinical practice
Metal titanium clips, as a common type of hemostatic clips, play an important role in clinical practice. Its unique physical properties, such as non-toxicity, light weight, high strength and excellent biocompatibility, make it an ideal choice for a variety of medical scenarios. In the process of endoscopic closure operations such as polypectomy, endoscopic submucosal dissection (ESD) and hemostasis, metal titanium clips have shown excellent hemostatic effects. In addition, it is often used for medical tasks such as auxiliary positioning, providing strong support for endoscopists. During the operation, in order to prevent potential risks such as delayed bleeding and perforation, endoscopists will flexibly use metal titanium clips to accurately clamp the wound according to the actual situation.
Metal titanium clips are made of titanium alloy and consist of two parts: clips and clamp tubes. The clips are designed for clamping and are intended to effectively prevent bleeding events. The clamp tube simplifies the release process of the clamp, making it more convenient. During the operation, negative pressure suction technology is used to promote the contraction of the wound surface, and then the titanium clamp is quickly closed to effectively clamp the bleeding site and its blood vessels. Through the endoscopic clamp channel, with the help of the titanium clamp pusher, the titanium clamp is accurately placed on both sides of the ruptured blood vessel. The design of the pusher knob enables the titanium clamp to vertically contact the bleeding site, and by slowly approaching and gently pressing the bleeding site, the operating rod is quickly retracted to lock the titanium clamp after the wound surface contracts, achieving precise hemostasis.

"Hemostasis operation of titanium clamp" should be treated with caution
When implementing titanium clamp hemostasis, a series of operating points must be followed. First, ensure that the design of the clamp and the clamp tube is appropriate. The clamp is used for clamping, while the clamp tube simplifies the release process. The two work together to achieve effective hemostasis. Secondly, the application of negative pressure suction technology is also crucial. It can promote wound contraction and create conditions for the precise placement and effective clamping of titanium clamps. In addition, through the cooperation of the endoscopic forceps channel and the titanium clip pusher, the metal titanium clip can be accurately placed on both sides of the ruptured blood vessel, and the design of the pusher knob allows the titanium clip to vertically contact the bleeding focus. During the operation, it is necessary to slowly approach and gently press the bleeding site, and quickly retract the operating rod to lock the metal titanium clip after the wound shrinks, so as to ensure the realization of accurate hemostasis.
Dietary recommendations
According to the size of the wound and the recovery situation, the patient needs to follow the doctor's advice to gradually transition from liquid diet to semi-liquid and normal diet. In the next 2 weeks, avoid eating crude fiber vegetables, fruits, and spicy, rough, and irritating foods, such as dragon fruit, animal blood and liver, which may change the color of the stool. At the same time, control the amount of food and keep the stool unobstructed to prevent constipation from causing increased abdominal pressure. If necessary, laxatives can be used to assist defecation.
Rest and activity guidance
Getting up and moving may cause dizziness and bleeding from the lesion, so it is recommended that patients reduce activity after treatment and rest in bed for at least 2-3 days after surgery. Avoid strenuous exercise. After the symptoms and signs stabilize, you can gradually increase the amount of aerobic exercise, such as walking, 3-5 times a week, but you still need to avoid sitting, standing, walking for a long time within 1 week, let alone strenuous exercise. At the same time, you should keep a happy mood and avoid coughing or holding your breath to prevent emotional excitement from causing adverse consequences. Physical activity should be avoided within 2 weeks after surgery.
Observation of titanium clip shedding
Within 1-2 weeks after surgery, the metal titanium clip may fall off by itself due to the formation of local granulation tissue in the lesion and be excreted from the body with feces. If it falls off too early, it may cause bleeding again. Therefore, patients need to pay attention to whether they have persistent abdominal pain, bloating, changes in stool color, etc. If the titanium clip does not fall off for a long time or is suspected to fall off too early, an X-ray abdominal plain film or endoscopic review can be performed to observe the shedding situation. It should be noted that the titanium clip of some patients may remain in the body for a long time or even for 1-2 years. In this case, the titanium clip can be removed under endoscopy according to the patient's wishes.

The impact of hemostatic clips on CT/MRI examinations
Hemostatic clips are a medical device that is often used to stop bleeding after surgery. However, this metal product may have a certain impact on subsequent CT or MRI examinations. Metal products will produce artifacts in CT scans, interfering with the clarity of the image, thereby affecting the doctor's diagnosis. Similarly, in MRI examinations, hemostatic clips may also shift due to the magnetic field, further affecting the accuracy of the examination results. Therefore, before undergoing such examinations, patients need to inform their doctors in advance of the presence of hemostatic clips in their bodies so that doctors can make corresponding preparations and adjustments.
Since titanium clips are non-ferromagnetic metals, this type of material will not move or shift significantly in a magnetic field, so its stability in the human body is excellent and will not pose a threat to the examiner. Despite this, the density of pure titanium is relatively high, and it will produce tiny artifacts during MRI imaging, but this effect usually does not interfere with the accuracy of the diagnosis.
