Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following description of the present invention with reference to the accompanying drawings and specific embodiments is provided for clarity and completeness.

Example 1

The fetching device shown in fig. 1-7 comprises a conduit 1, a pull rod 6 and a collecting part, wherein the pull rod 6 is driven to drive the collecting part to be pushed out or retracted along the conduit 1. The volume of the collecting part becomes larger after the pull rod 6 is pushed out.

As shown in fig. 1 to 5, the collecting part includes a circular supporting member 2, a plurality of spring strips 3, and a collecting bag 4, one end of each of the spring strips 3 is fixed on the supporting member 2, the other end is freely disposed, the collecting bag 4 covers the outside of each of the spring strips 3, and a pathological inlet 5 is disposed on the collecting bag 4.

The pull rod 6 is driven to push out the collecting part along the catheter 1, the free end of the spring piece 3 is scattered, and the collecting bag 4 and the pathological entrance 5 are spread and enlarged to form a collecting cavity. The volume of the collection bag 4 after being unfolded is enlarged, and the pathological entrance 5 is correspondingly opened while being unfolded. The pull rod 6 is driven to pull the collecting part along the catheter 1, and the spring piece 3 drives the collecting bag 4 to be tightened and retracted to the catheter 1.

A plurality of spring leaves 3 evenly distributed are on support piece 2, and spring leaf 3 free end outwards struts under free state, and after a plurality of spring leaves 3 strut, make the volume grow of collecting bag 4, conveniently put into pathological tissue, and the area that the free end struts is greater than support piece 2's cross-sectional area, makes the cross section of collecting bag 4 after strutting to be big to be isosceles trapezoid. The spring leaf 3 can also bulge outwards after being opened, so that the whole collecting bag 4 is in a lantern shape and the size is increased. In this embodiment, the cross-sectional area of the stretched collecting bag 4 is substantially isosceles trapezoid.

In this embodiment, the free end ring of the spring plate 3 is provided with the supporting ball 20, which can effectively prevent the spring plate 3 from puncturing the collecting bag when being opened, and avoid hidden troubles such as liquid leakage.

The edge of the pathological inlet 5 is penetrated with a closing line 7, and when the spring piece 3 props the collecting bag 4, the closing line 7 at the pathological inlet 5 is not also propped. In this embodiment, the support member 2 is a support ring, and the support ring is matched with the inner wall of the conduit 1. A sealing rubber 8 is fixed in the supporting ring, a cut 9 which can be opened in a sealing way is formed in the sealing rubber 8, and a tensioning end 10 of the closing-in line 7 penetrates through the sealing rubber 8 and the conduit 1 and then is exposed outside.

When the collecting part is drawn towards the catheter 1, the tightening end 10 can be drawn simultaneously to tighten the closing-up line 7, so that the pathological entrance 5 is tightened and sealed, and the outflow of pathological tissues or liquids carried by the pathology is prevented. The cut 9 arranged on the sealing rubber 8 can enable the closing-in line 7 to pass through and can play a role of sealing. The notch 9 is formed by cutting through and penetrating the sealing rubber 8 by a knife or the like, but the lower corner is not cut off or cut off, the sealing rubber 8 is in a normal sealing state under an unstressed state, and an object starts to pass through when the stress is applied.

As shown in fig. 1-5, a sealing member 11 is disposed at a push-pull port of the catheter 1, an operation window 12 is disposed on a wall of the catheter 1, and a protective cover 13 capable of being opened and closed is disposed on the operation window 12. In this embodiment, an operating forceps is further provided, and the operating forceps is gun-shaped and includes two forceps handles 14 hinged together, a forceps rod 15 driven by the two forceps handles 14, and two jaw pieces 16 disposed at the end of the forceps rod 15.

As shown in fig. 5, the forceps rod 15 of the operating forceps can pass through the sealing rubber 8 into the collecting bag 4 through the operating window 12 for related operation, and because the sealing rubber 8 provided with the notch 9 is used for sealing, when the operating forceps extend into the collecting bag 4 from the sealing rubber 8, the insertion opening of the sealing rubber 8 can be in a sealed state because of the flexibility and elasticity of the rubber.

After the catheter 1 is inserted into the abdominal cavity along the abdominal incision, the collection bag 4 is pushed open by the physician, and the relevant pathological tissue (e.g., appendix, cecum, etc.) is then inserted into the collection bag 4 through the pathological entrance 5. When the collecting bag 4 is tightened to the catheter, in order to prevent the pathological tissues from being clustered, the operating forceps can be extended from the operating window 12 and the sealing rubber 8 to put or pull the pathological tissues into a strip shape, so that the collecting bag 4 can be conveniently put into the catheter 1. The pathological tissue can also be straightened out by operating the forceps while the collection bag 4 is drawn into the catheter 1. When the collecting bag is pulled into the catheter 1, the spring piece 3 can generate certain deformation, so that the pathological tissues can be clamped, and the pathological tissues are prevented from falling off when the collecting bag 4 is folded. When the operation is performed, the protective cover 13 is opened, and when the operation window 12 is not used, the protective cover 13 is tightly closed.

When taking out pathological tissues such as gall bladder, the puncture needle, the liquid aspirator and the like can also be inserted from the operation window 12 and the sealing rubber 8 to aspirate the gall bladder liquid first, so as to avoid liquid leakage and reduce the volume of the gall bladder liquid, so that the collection bag 4 can be pulled to the catheter 1 more smoothly.

The two jaw pieces 16 are oval, and in order to effectively clamp pathological tissues, a protrusion 17 and a groove matched with the protrusion 17 are respectively arranged at the engagement part of the two jaw pieces 16.

As shown in fig. 1 to 5, the pull rod 6 comprises a handle 18 and a connecting rod 19, wherein one end of the connecting rod 19 is fixed on the handle 18, and the other end is fixed on the support 2. In order to facilitate the smooth passing of the operation forceps through the inner cavity of the catheter 1 and avoid the interference between the operation forceps and the connecting rod 19, the connecting rod 19 is made of hard medical metal material and is embedded in the groove on the inner wall of the catheter 1, and the whole collecting part can be effectively prevented from rotating in the catheter 1 to influence the operation forceps when the collecting bag 4 is tightened.

Example 2

As shown in fig. 8 to 10, unlike embodiment 1, the collecting part includes a collecting box 21 having an internal cavity, and a collecting port 22 is opened on a side wall of the collecting box 21. The collecting box 21 is adapted to the catheter 1; the pull rod 6 comprises a handle 18 and a connecting rod 19, and the connecting rod 19 is connected with the end part of the collecting box 21.

The collection box 21 can hold strips of pathological tissue, such as appendices, cecum, etc. In use, the collecting box 21 is pushed out, and then pathological tissues are put into the collecting box 21 along the collecting opening 22, and then the collecting box 21 is put into the catheter 1. After the collecting box 21 is put into the guide pipe 1, both ends of the collecting box 21 are sealed with the guide pipe 1, so that liquid can be effectively prevented from spilling.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
