Abstract

Technical Field
[0001] The utility model belongs to the technical field of medical instruments, in particular to a kind of in vivo particle sampling forceps. Background Art
[0002] In the field of medicine and biology, one tool used for sampling particles in the body is the biopsy forceps. Biopsy forceps are surgical tools designed to obtain small samples from biological tissues for further pathological or cytological examination. These samples are usually collected through endoscopy or other surgical means. The types and designs of biopsy forceps vary depending on the purpose. Here are some common types: 1. Endoscopic biopsy forceps: This type of biopsy forceps is usually used for endoscopic examinations and is guided into the body through a tube or instrument to obtain samples in deeper tissues. Endoscopic biopsy can be used for internal organs such as the digestive tract and respiratory tract. 2. Surgical biopsy forceps: This type of biopsy forceps is designed more for surgical procedures, such as laparotomy or other surgical procedures. They can be used to obtain tissue samples during surgery. 3. Soft tissue biopsy forceps: Specialized biopsy forceps used to obtain soft tissue samples. These samples may come from skin, muscle or other soft tissue areas. 4. Bone biopsy forceps: Specially designed biopsy forceps used to obtain samples from bone structures. This may be used in the diagnosis of bone marrow or bone lesions. Tissue sampling with biopsy forceps is usually done to confirm or evaluate disease, understand cellular structure, or conduct biological research.
[0003] However, the following problems exist in the process of sampling particulate matter using biopsy forceps: due to the small size of particles in the body, the sampling forceps are often unable to clamp them well, and at the same time, the particles in the body and the sampling forceps will also have certain adhesion problems, making it difficult for them to fall off the sampling forceps. Utility Model Content

[0009] Furthermore, the push rod body is slidably mounted in the moving path and the moving hole.
[0010] Furthermore, the inner concave portion of the clamping concave plate is designed as a curved surface, which can well wrap and clamp the internal objects in the whole range. At the same time, the symmetrically distributed clamping concave plates can cooperate with each other to form a closed cavity to clamp and remove the particles.
[0011] Furthermore, the clamping concave plate is fixedly welded to the end portions of the first pliers body and the second pliers body respectively.
[0012] Furthermore, the first pressure plate is fixedly connected to the return spring, and the return spring is fixedly connected to the first caliper body and the second caliper body respectively.
