Capsule gastroscope remove deviceTechnical Field
The invention relates to the field of medical instruments, in particular to a capsule gastroscope taking-out device.
Background
With the development of medical technology, capsule gastroscopy has become the choice of more and more patients, and noninvasive painless and anesthesia gastroscopy is really realized. However, some patients have structural abnormalities in the digestive tract that do not allow for proper drainage, such as an obstruction in the digestive tract, a large ulcer, or an outward bulge in the intestinal wall that forms a diverticulum. At the moment, the capsule endoscope needs to be taken out of the body by means of a gastroscope or an enteroscope.
At present, no device specially used for taking out the capsule gastroscope exists, and the snare is stretched into an endoscope channel to sleeve the capsule gastroscope and then is withdrawn along with the endoscope in a common way. Because the surface of the capsule gastroscope is smooth and has no edges and corners, the snare is difficult to be sheathed, and the whole taking-out process is time-consuming and labor-consuming.
In view of the above, it is an object of the present invention to provide a capsule gastroscope removing device to achieve rapid capsule gastroscope removal.
Disclosure of Invention
In view of this, the main objective of the present application is to provide a capsule gastroscope extractor, which utilizes the magnetic positioning principle to quickly and axially position the head end of the capsule gastroscope, and utilizes the elastic gripper to stretch out and wrap the capsule gastroscope, so as to realize effective extraction of the capsule gastroscope.
The invention provides a capsule gastroscope extractor which comprises an outer sheath component, a mandrel component and an operation component, wherein the outer sheath component comprises an outer sheath body, a cross opening and a magnetic part, the cross opening is arranged at the far end of the outer sheath body, and the magnetic part is positioned in the middle of the cross opening; the mandrel component penetrates through the outer sheath component and comprises a mandrel body, a gripper and an elastic sleeve piece, the gripper extends out of the far end of the mandrel body, the gripper comprises four gripping arms, and the head ends of the gripping arms are connected in series through the elastic sleeve piece; the operating component is positioned at the near ends of the mandrel component and the sheath component and comprises a handle and a sliding block, a sliding groove for the sliding block to actuate is formed in the handle, the sliding block is fixedly connected with the near end of the mandrel body, and the handle is fixedly connected with the near end of the sheath body so as to realize the axial movement of the in-vitro sliding block relative to the handle and convert the axial movement of the mandrel component relative to the sheath component; the mandrel body slides towards the far end in the sheath body, and the hand grip extends out of the cross opening of the sheath component and is propped open at the near end under the interference of the magnetic part; meanwhile, the elastic sleeve provides tension for the head end of the gripping arm so as to realize radial contraction of the cantilever at the head end of the gripper after the cantilever extends out.
Optionally, in an embodiment of the present application, the outer sheath body has an outer diameter of 1mm to 3 mm.
Optionally, in an embodiment of the present application, the outer sheath body is a flexible member.
Optionally, in an embodiment of the present application, the mandrel body is a flexible member.
Optionally, in an embodiment of the present application, the grip is made of an elastic metal material.
When the capsule gastroscope extractor is used, the capsule gastroscope extractor is conveyed to a capsule gastroscope to be extracted through an endoscope channel, the far end of the capsule gastroscope extractor is quickly connected with the head end of the capsule gastroscope through the interaction of a magnetic part and a magnetic head in the capsule gastroscope, and the axis of the capsule gastroscope is connected with the axis of the end face of the capsule gastroscope extractor in a tangent mode; then the sliding block is pushed to realize that the gripper extends out of the cross-shaped opening, the proximal end of the gripper is opened under the collision of the magnetic part, and the head end of the gripper is bound by the elastic sleeve; along with stretching out of tongs, the increase of grabbing arm cantilever length, when the grabbing arm head end stretches to capsule gastroscope distal end, the tongs forms the binding off under the effect of elastic sleeve spare, wraps up the capsule gastroscope, can realize withdrawing when capsule gastroscope and scope this moment, and whole process of taking out is simple effective, reduces the painful time of patient.
