Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

Wherein, 1 is coil, 101 is coil head, 102 is thermal fusion, 103 is pull ring, 2 is fetching bag, 3 is sleeve pipe, 4 is control guide wire, 5 is developing mark.

Detailed Description

The invention will now be further described with reference to the accompanying drawings and examples.

Fig. 1 shows a preferred embodiment of the invention. In the embodiment, the foreign body taking net bag for the endoscope comprises a coil 1, an object taking bag 2, a sleeve 3 and a control guide wire 4; wherein, the article taking pocket 2 is made of a plastic film and is provided with an opening; the coil 1 is made of nickel-titanium alloy, stainless steel or nylon and has good elasticity and strength, and the coil 1 comprises a coil head 101, a hot melt bond 102 and a pull ring 103. The loop head 101 is an annular handle structure formed by a filament loop, and the annular part of the loop head is oval or circular. The proximal end of the coil head 101 and the distal end of the pull ring 103 are connected into an integral structure through a hot melt bond 102; the sleeve 3 is a transparent hollow tubular structure, the wall thickness of the sleeve is 0.15 mm-0.25 mm, and the sleeve has certain elasticity.

When the foreign body taking net bag for the endoscope is in a conveying state in a cavity, the coil 1 and the object taking bag 2 are both contracted in the sleeve 3, and the near end of the sleeve 3 is held by an operator; when the object-taking place is reached, the coil 1 and the object-taking pocket 2 are pushed out of the sleeve 3 by controlling the guide wire 4 to take the object; after the target object is taken, the control guide wire 4 is pulled back to retract the coil 1, the object fetching pocket 2 and the target object into the sleeve 3.

The coil head 101 of the coil 1 is tightly glued with the outer edge of the object taking pocket 2, so that the object taking pocket 2 is fixed on the coil 1 through an opening; preferably, get the thing pocket and open and have 2 apertures, snatch the foreign matter fast after, can effectively get rid of the air and the internal liquid in the pocket. The coil head 101 of the coil 1 is provided with development marks 5, and the number of the development marks 5 is generally 1 to 3. In actual operation, the developing mark 5 can effectively position the fetching pocket 2 in the human body, thereby facilitating the operation of doctors.

The control guide wire 4 is fixedly connected with the pull ring 103. In the actual operation process, an operator can control the whole retraction of the coil 1 or the pushing out of the sleeve 3 at the far end by controlling the operation of the guide wire 4. The coil head 101 and the retrieval bag 2 fixed thereon are pulled into the sleeve 3 in vitro. When the endoscope system is in a human body, the coil head 101 reaches a position where foreign matters exist under the guidance of the endoscope system, the coil head 101 fixed with the object taking pocket 2 is pushed out of the sleeve 3 through the control guide wire 4, the foreign matters are accurately positioned through the developing marks 5 on the object taking pocket 2, and then the foreign matters are captured by the object taking pocket 2. The captured foreign body is pulled back by the control guide wire 4, so that the fetching bag 2 wrapping the foreign body is fixed at the head part at the far end of the sleeve 3 together with the foreign body, and the human body is withdrawn along with the sleeve 3, thereby achieving the purpose of treatment.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
