Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0040] Such as figure 1 As shown, a magnetically controlled biopsy forceps device for capsule endoscope provided according to the present invention includes a housing, a biopsy forceps, and a one-way ratchet, a ratchet baffle, a shape memory spring group, and a ratchet shifting piece arranged in the housing. The biopsy forceps can extract sample tissue; the one-way ratchet is used to release the biopsy forceps to the sampling area, and recover the biopsy forceps and the samples on them under the conditi...

Abstract

The invention provides a magnetically controlled biopsy forceps device for capsule endoscope and a using method thereof. The device comprises a shell, a pair of biopsy forceps, and a one-way ratchet wheel, a ratchet wheel baffle, a shape memory spring assembly, a ratchet wheel stirring sheet and other parts which are arranged in the shell, wherein the shape memory spring assembly can be extended or retracted by changing temperature, so that opening and closing of the ratchet wheel baffle can be controlled, and releasing and winding up of wires of the biopsy forceps can be controlled; the one-way ratchet wheel can complete wire winding-up of the biopsy forceps under control of the ratchet wheel stirring sheet, and passive driving of an in-vitro permanent magnet is formed on the ratchet wheel stirring sheet; and the spring piston can be used for assisting the biopsy forceps to clamp an extracted tissue sample in the winding-up phase of the biopsy forceps.

Description

technical field [0001] The invention relates to the technical expansion of capsule endoscopy and the field of medical monitoring, in particular to a magnetically controlled biopsy forceps for capsule endoscopy and a method for using the same. Background technique [0002] Endoscopic examination or surgery is one of the most commonly used clinical methods, and various biopsy materials obtained through endoscopy are indispensable methods for confirming diseases. With the current development of medicine, the limitations of conventional endoscopy are gradually solved by capsule endoscopy, which also stimulates the development of capsule endoscopy biopsy sampling equipment. [0003] At present, most of the medical biopsy forceps are designed based on conventional endoscopes. These biopsy forceps are connected by wires, and due to the limitations of conventional endoscopes, it is necessary to open holes in the subject's body or insert them through the esophagus. To the lesion are...
