Abstract
The invention relates to a medical apparatus and instrument, in particular to rotatable net-shaped foreign matter forceps. The rotatable net-shaped foreign matter forceps comprise a net-shaped forceps head, an inner tube, a core rod and a sliding ring; the sliding ring is arranged on the core rod and slides in the axial direction of the core rod; the inner tube is sleeved with an outer tube; the outer tube is fixedly connected with the core rod through a rotating cap; a flexible stop piece facing the center of the net-shaped forceps head is formed on a frame of the net-shaped forceps head; the tail end of the net-shaped forceps head is connected with a nickel-titanium wire through a butt joint pipe; the nickel-titanium wire is installed in the inner tube which is pushed by the sliding ring so that the inner tube can stretch out of the outer tube for treatment. The whole nickel-titanium wire is used for replacing a stainless steel wire rope, and rotating performance is better; the inner tube is used, idling of a handle is reduced, and hand feeling of operation is better; the flexible stop piece facing the center of the net-shaped forceps head is formed on the frame of the net-shaped forceps head, and it is guaranteed foreign matter does not slide out of the forceps in the taking-out process.
Description
Technical field
The present invention relates to a kind of medicine equipment, especially a kind of rotatable net type foreign body forceps.
Background technology
At present, net type foreign body forceps is mainly used in the taking-up to the polyp after being cut into or other foreign matters under scope. In clinical use procedure, need to adjust string bag direction according to lesions position, direction by the rotation string bag realizes, the common net type foreign body forceps using clinically at present, when rotation, head is beated, rotation has some setbacks, and is difficult to reach the requirement of the even smooth and easy rotation string bag of energy, and main cause is that common Cable cannot meet the demands.
The patent No. 201320511450.8 discloses a kind of easy rotation net type foreign body forceps, comprise the string bag, drag-line, outer tube, turncap, guide pipe, slip ring and handle, drag-line plug-in mounting within the outer tube, described drag-line comprises flexible steel cable and titanium-nickel wire, one end of flexible steel cable is fixedly connected with the tail end of the string bag, the other end is fixedly connected with one end of titanium-nickel wire, and the other end of titanium-nickel wire is fixedly connected with the head end of guide pipe. More difficult owing to restoring to the original state after stainless steel wire rotation, so in the time of operation, have rotation situation not in place and occur, and then affect result for the treatment of. In addition, when the polyp of taking-up or other foreign matters are less with respect to the string bag, likely skid off the string bag, make troubles to treatment.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides the rotatable net type foreign body forceps that better, the anti-foreign matter of a kind of rotatory skids off.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rotatable net type foreign body forceps is provided, comprise net type binding clip, inner tube, core bar and slip ring, described slip ring is arranged on core bar, and along its axial slip, described inner tube is set with outer tube outward, described outer tube is connected and fixed by turncap and core bar, described net type binding clip frame is provided with the flexible catch towards its center, the tail end of net type binding clip is connected with titanium-nickel wire by butt tube, described titanium-nickel wire is arranged in inner tube, inner tube is promoted by slip ring, treats to stretch out outer tube.
Further, the upper and lower end of described slip ring and the rear end of core bar are equipped with the finger-hole for finger manipulation.
The invention has the beneficial effects as follows: use whole titanium-nickel wire to replace stainless steel steel wire rope, rotatory is better; Use inner tube, reduce handle diastema, operating handle is better; Net type binding clip frame is provided with the flexible catch towards its center, ensures that in taking-up process, foreign matter does not skid off.

In figure: 1. net type binding clip, 2. butt tube, 3. titanium-nickel wire, 4. inner tube, 5. outer tube, 6. turncap, 7. finger-hole, 8. slip ring, 9. core bar, 10. flexible catch.
Detailed description of the invention
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention instead of limitation of the invention further.
As shown in Figures 1 to 3, a kind of rotatable net type foreign body forceps, comprises net type binding clip 1, inner tube 4, core bar 9 and slip ring 8, and slip ring 8 is arranged on core bar 9, and along its axial slip, the outer outer tube 5 that is set with of inner tube 4, outer tube 5 is connected and fixed by turncap 6 and core bar 9, and net type binding clip 1 frame is provided with the flexible catch 10 towards its center, the tail end of net type binding clip 1 is connected with titanium-nickel wire 3 by butt tube 2, titanium-nickel wire 3 is arranged in inner tube 4, and inner tube 4 is promoted by slip ring 8, treats to stretch out outer tube 5.
As shown in Figure 1, the rear end of the upper and lower end of slip ring 8 and core bar 9 is equipped with the finger-hole 7 for finger manipulation.
When use, operator's finger stretches into finger-hole 7 and handles slip ring 8 and release forward net type binding clip 1, in the time of needs rotation net type binding clip 1, and on the other hand fixing turncap 6, rotate on the other hand core bar 9, now core bar 9 drives titanium-nickel wire 3, has driven net type binding clip 1 to rotate simultaneously, reaches the requirement of use, polyp or other foreign matters fall into the flexible catch 10 of net type binding clip 1 interior quilt and block, can not skid off, the design uses whole titanium-nickel wire to replace stainless steel steel wire rope, and rotatory is better; Use inner tube, reduce handle diastema, operating handle is better. Net type binding clip 1 of the present invention has better rotatory, and rotation steadily evenly, facilitates clinical operation operation.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely. The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
