Description

The middle ear polypus forceps of clamping polyp downwards

Technical field

The utility model belongs to middle ear polypus forceps field, more particularly to a kind of middle ear polypus forceps of the polyp of clamping downwards.

Background technique

Middle ear polypus forceps is a kind of medical instrument, for clamping the polyp at middle ear, middle ear polypus forceps in operation on the middle ear It generally requires and works under Endoscope-assisted.It includes fixing head and activity that directly pincers, which take the collet of polyp, on middle ear polypus forceps Head, movable head are located at the top of fixing head, and always with two tong arms all in linear state, movable head is only being closed fixing head When with two tong arms be in linear state, when movable head open when, movable head is dug upwards, i.e., upwards clamping cease Meat.The clamping of this structure is also inconvenient to clamp the polyp positioned at middle ear lower part less than the polyp of endoscopic visual edge. When firmly clamping polyp, longer tong arm is easily deformed existing middle ear polypus forceps, is easy between two tong arms lateral Separation causes polyp clamping failure.

Therefore, existing middle ear polypus forceps, which exists, clamps less than endoscopic visual edge polyp, is inconvenient to clamp middle ear Lower part polyp and the defect for be easy to causeing polyp clamping failure.

Utility model content

The purpose of the utility model is to provide a kind of middle ear polypus forceps.The utility model have can clamp interior peep Polyp at mirror vision periphery facilitates clamping middle ear lower part polyp and does not allow the advantages of easily causing polyp clamping failure.

The technical solution of the utility model includes: the middle ear polypus forceps of clamping polyp, including first handle downwards, first handle Lower end is equipped with first and refers to circle, and the top of first handle is connect by first rotating shaft with second handle, and the upper end of first handle is fixed There is the first tong arm, the end of the first tong arm is equipped with fixing head obliquely, and 40-50 ° of angle of fixing head and the first forearm；Second The lower end of handle is equipped with second and refers to circle, and second handle upper end is connect by the second axis with the second tong arm, and the second tong arm passes through third Axis is connect with movable head, and movable head is connect by the 4th shaft with the end of the second tong arm, and the movable head is located at fixing head Lower section.

In the middle ear polypus forceps of downward clamping polyp above-mentioned, first tong arm includes the connect with first handle One postbrachium, the first postbrachium are connect by the first transfer block with the first forearm, and the fixing head and the end of the first forearm are mutually solid It is fixed；Second tong arm includes the second postbrachium connecting with second handle, before the second postbrachium passes through the second transfer block and second Arm connection, the movable head are connect with the end of the second forearm；First postbrachium is located at the lower section of the second postbrachium, and described One transfer block is located at the side of the second transfer block, and first forearm is located at the top of the second forearm.

In the middle ear polypus forceps of downward clamping polyp above-mentioned, the junction of the first handle and the first tong arm is equipped with logical Hole, the upper end of second handle are connect after passing through through-hole with the second tong arm, the first rotating shaft pass perpendicularly through through-hole with it is first-hand Handle is mutually fixed；The bottom surface of first forearm is equipped with sliding slot, and the top surface of second forearm is equipped with to be matched with sliding slot Sliding block.

Compared with prior art, the collet of the utility model is direction obliquely, digs direction when movable head is opened It is that downward, i.e., clamping polyp, the collet being arranged so more adapt to the structure of middle ear downwards, is not only able to clamping and is regarded to endoscope The polyp of wild edge, and the polyp positioned at middle ear lower part can easily be clamped.By the cooperation of sliding slot and sliding block, so that The limit point for preventing tong arm from deforming is increased between first tong arm and the second tong arm newly, so that between the first tong arm and the second tong arm It is not easy laterally separated, it is not easy to cause polyp clamping failure.

Therefore, the utility model, which has, can clamp endoscopic visual edge polyp, facilitate clamping middle ear lower part breath Meat and not allowing easily causes the advantages of polyp clamping failure.
