Abstract
The utility model relates to a mesh basket-shaped calculus protractor, which is characterized in that: draw steel wires connected with a moving handle pass through a four fluorine tube and then are connected with the mesh basket body respectively. When in use, the steel wires of the utility model will splay automatically according to the given crease when the mesh-shaped steel wires extending out of the four fluorine tube, wherein, the two pieces of steel wires at upper section are ranged widely in splaying, thus making the calculus easily dropped in the mesh basket; then the utility model fraps the steel wires through the operating handle and fixes the calculus into the mesh basket, then the protractor takes out the calculus together with the endoscope; therefore, the utility model can take out the calculus conveniently even in large bulk.
Description
Technical field:
This utility model relates to technical field of medical, and specifically a kind of biopsy channel hole that utilizes fujinon electronic video endoscope takes out the apparatus of calculus or foreign body.
Background technology:
The basket shape dislodger of prior art is all made with relatively-stationary four steel wires at present, a lot of weak points are arranged during use, be mainly reflected in need rely on when extracting JISHI and human body in wall friction slit between steel wire is enlarged just can pack into JISHI, therefore bigger JISHI is difficult to be entangled by basket, and less JISHI drops easily.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved basket shape calculus protractor, and it can overcome some shortcomings of the prior art.
To achieve these goals, the technical solution of the utility model is: basket shape calculus protractor, it mainly comprises the fixed handle of being with chute, the moving handle that is slidingly connected with fixed handle, the four fluorine tube that is connected with fixed handle is characterized in that: the traction steel wire that is connected with moving handle links to each other with the basket body respectively after passing four fluorine tube.
When the steel wire of basket shape of the present utility model stretches out four fluorine tube during use, steel wire can open automatically according to folding line in advance, the open scope of steel wire that the top is two is bigger, make calculus fall into basket easily, tighten up steel wire by operating grip then, the bigger calculus of volume calculus is fixed in the basket takes out together, even if also can be taken out easily with scope.
Description of drawings:
Fig. 1 is the structural representation of this utility model one embodiment
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
This utility model mainly comprises the fixed handle 1 of being with chute, the moving handle 2 that is slidingly connected with fixed handle 1, the four fluorine tube 9 that is connected with fixed handle 1 is characterized in that: the traction steel wire that is connected with moving handle 2 links to each other with the basket body respectively after passing four fluorine tube 9.The basket body is made up of four steel wires at least, and an end of basket body steel wire is combined into one, and as the front end of basket, one or two root knot integrators of the other end become one group, and remaining several root knot synthesizes another group of one, all as the rear end of basket.Moving handle 2 is made up of active part 7 and phantom element 6 two parts, supports with spring 8 between two parts.Traction drive steel wire 3 has two, and not isometric, is individually fixed in the active and the phantom element of moving handle 2.
In the present embodiment, far-end is the basket of a similar palace lantern shape of being made up of through bending four or four above steel wires, the front end of steel wire combines through processing at the front end of basket, rear end at basket, steel wire 4 is longer, steel wire 5 is to shorter, and two groups of steel wires link to each other with moving handle 2 by traction steel wire respectively.When moving handle 2 in the chute of fixed handle 1 when far-end moves because of the effect of spring 8, phantom element 6 and active part 7 keep synchronously, phantom element 6 is hindered by it when the mobile guide runner end, this moment, the front end basket stretched out fully, according to folding line, open shaping by elastic force, steel wire 5 promptly no longer forward.Continue forward and still can drive steel wire 4 behind the active part 7 compressed springs 8, make basket form door opening state, so that extract the JISHI foreign body, moving handle 2 is moving to travelling backwards during withdrawal, phantom element 6 and active part 7 restore by the elastic force of spring 8, basket is closed the door, tighten up steel wire by operating grip then, calculus is fixed in the basket takes out together with scope.
Claims (4)
