As endoscopic diagnosis and treatment technologies advance rapidly, how can gastrointestinal lesions be resected with minimal trauma and high efficiency? The emergence of Disposable Polypectomy Hot Snare offers a novel solution for both clinicians and patients. These devices are not merely precise instruments for minimally invasive surgery, they represent an innovative tool that reduces infection risks and enhances surgical safety.
Disposable Hot Polypectomy Snares are common endoscopic consumables used in endoscopic therapy. The product primarily consists of a handle, finger loops, electrodes, end caps, soft tips, outer sheaths, and cutting wires. Through the synergistic effect of high-frequency current and mechanical cutting, it enables precise resection of lesion tissues.
It is indicated for the removal of gastrointestinal polyps, as well as elevated and flat lesions, and even early gastrointestinal cancers (e.g., MBM). It serves as a core instrument for endoscopic procedures such as Endoscopic Mucosal Resection (EMR) and polypectomy.
Advantages of the Hot Polypectomy Snares
Snares are categorized into Hot Polypectomy Snares and Cold Polypectomy Snares based on whether they conduct electricity.
In clinical applications, Hot Polypectomy Snares (specifically, snares combined with high-frequency current) demonstrate significant advantages over traditional Cold Polypectomy Snares. They excel particularly in terms of hemostatic effect, surgical efficiency, range of indications, and complication control. Below is a detailed analysis of these specific clinical advantages:
|
Item |
Polypectomy Hot Snares |
Polypectomy Cold Snares |
| Hemostatic Capacity | Hemostasis through high-frequency current: Minimizes bleeding during and after surgery. | Relies solely on mechanical constriction, offering limited hemostatic efficacy and posing a high risk of delayed bleeding. |
| Cutting Efficiency | Combines electro-cutting and mechanical action to swiftly sever tissue. | Mechanical cutting only; time-consuming. |
| Range of Indications | Suitable for the resection of flat-based polyps, larger lesions, and hypervascular tissue. | Limited to small polyps or those with thin, long peduncles. |
| Risk of Tissue Damage | Targeted coagulation prevents collateral tissue damage. | The mechanical traction force can easily cause submucosal tearing or perforation. |
| Postoperative Complications | Significantly reduces the risk of bleeding and perforation. | High risk of bleeding and infection. |
Data support: Clinical statistics indicate that the postoperative bleeding rate with Hot Polypectomy Snare is 50%-70% lower than that of Polypectomy Cold Snare.
Applications of Different Loop Shapes
Snare loops are categorized by shape into: Oval, Crescent and hexagonal. These variations allow for precise ligation of lesions ranging from diminutive polyps to larger flat lesions, minimizing the need for piecemeal resection and thereby enhancing procedural efficiency.
1. Oval: The most common shape, suitable for capturing typical polyps.
2. Crescent: Designed for capturing polyps in challenging or hard-to-reach locations.
3. Suitable for capturing flat polyps.
Clinical Applications: From Polypectomy to Early Cancer Intervention
● Colorectal Polypectomy: Rapid Eradication, Reduced Recurrence
Pain Point: Sessile polyps have rich blood supply at the base. Traditional ligation often results in residual tissue or delayed hemorrhage.
Solution:
1．Versatile Sizing: A range of loop diameters (10–30mm) ensures precise matching to polyp size, enabling rapid capture at the base and complete lesion resection, thereby minimizing the risk of residue.
2．Simultaneous Hemostasis: The high-frequency electrosurgical mode provides concurrent hemostasis, significantly reducing the risk of postoperative bleeding.
3．Clinical Evidence: Comparative studies at a specific hospital demonstrated that the use of disposable snares reduced polyp residual rates from 8% to 2%, with a 40% decrease in postoperative bleeding rates.
● EMR for Early GI Neoplasia: Complete Excision, Reliable Diagnosis
Figure Legend: EMR Procedure Steps Panel A: A 0.8 × 0.8 cm semi-pedunculated polyp is observed in the colon. Panel B: The lesion exhibits a distinct lift (positive lift sign) following submucosal injection of a solution containing indigo carmine, epinephrine, and normal saline. Panels C–D: The lesion is progressively encircled at its base using a snare. The wire is tightened, and the lesion is resected via electrosurgical current.Panel F: The wound defect is closed with endoclips to prevent hemorrhage.
● Emergency Hemostasis: Rapid Response, Saving Lives in Critical Situations
Pain Point: The bleeding sites of ulcerative hemorrhage or Dieulafoy lesions are often concealed, making precise localization difficult for conventional electrosurgical forceps.
Solution: Featuring a 360° rotating handle and a slim catheter design, the device easily accesses complex anatomical regions such as the descending duodenum. The intelligent coagulation mode rapidly seals the bleeding point, significantly shortening rescue time.

ZRHmed Disposable Hot Polypectomy Snare is designed to work in conjunction with flexible endoscopes and high-frequency surgical generators for the resection of gastrointestinal polyps.
It utilizes the thermal energy generated by high-frequency current to rapidly heat the targeted tissue, causing protein denaturation, coagulation, and vaporization, thereby achieving a precise cutting effect. This technology offers the advantages of minimal invasiveness, rapid recovery, and reduced bleeding, making it widely adopted in clinical practice.
