Description
Technical field
The utility model relates to medical instrument, more specifically to a kind of blood vessel separating knife.
Background technique
Currently without the surgical instrument separated dedicated for ciliary anterior artery, once had scholar using iridectomy hook, foreign matter pick knife,
A variety of auxiliary tools such as cystotome, article tape could complete the separation of blood vessel, and operating procedure is many and diverse, and time-consuming, inefficiency.Afterwards
Come, clinical workers simplifies auxiliary tool in separating blood vessel, is cut using cyst membrane come separating blood vessel and muscular fascia group merely
It knits.But cyst membrane, which is cut, to be not easy to separate from muscle or fascia tissue, exposes blood vessel, so that separating blood vessel inefficiency, time-consuming；
It is also easy accidental injury blood vessel and causes bleeding；After cyst membrane cuts use for several times, the easy rust of the knife edge of scissors is even crimped, shearing effect
Rate is low.
In view of this, the designer passes through the experience accumulation of blood vessel lock out operation and continuous clinical test of many years, deeply
Design, and actively research improvement has a fling at and develops and design the utility model, with can be dedicated for being separated in micro- strabotomy
Ciliary anterior artery.
Utility model content
The purpose of this utility model is to provide a kind of blood vessel separating knives, can be good at separating blood vessel and muscle or fascia group
It knits, is not easy to accidentally injure blood vessel, simplify blood vessel separation application, reduce blood vessel separating difficulty.
In order to achieve the above objectives, the solution of the utility model is:
A kind of blood vessel separating knife is included in knife handle front end equipped with blade, and blade forms the cutter hub of an arc in knife handle front end,
Cutter hub front end forms point of a knife, and cutter hub two sides put the first edge on a knife or a pair of scissors to form side edge.
Further, the flat sheet body of the arc-shaped strip of cutter hub shape, forms side edge at left and right sides of sheet body, and sheet body front end is upwards gradually
Arc bending is at the point of a knife for tilting shape.
Further, the length of cutter hub is 6mm, and the length for the point of a knife being upturned is 1.5 ± 0.1mm, the cutter hub of sheet
With a thickness of 0.5-0.8mm.
Further, the front end of knife handle is equipped with the connector of a taper, and cutter hub is arranged in connector front end.
Further, the end of cutter hub forms rod-shaped linkage section, and linkage section is arranged in connector front end.
Further, the length of knife handle is 75-87mm, and the width of knife handle is 4.5-5.3mm, the length of the connector of knife handle front end
Degree is 5mm, and the length of linkage section is 10mm.
Further, knife handle forms flat bar, is formed with anti-skid design in the grip portions of knife handle.
After adopting the above structure, the utility model can operate with and separate ciliary anterior artery in micro- strabotomy, this is practical
Novel parting tool has the advantage that
1, instrument good hand touch operates conveniently, and simplifies blood vessel separation application, reduces blood vessel separating difficulty, greatly shortens
Operating time；
2, be readily cleaned with aseptic process, be used for multiple times and will not reduce service efficiency；
3, it is good at separating blood vessel and muscle or fascia tissue, is not easy to accidentally injure blood vessel, operative hemorrhage is few, can separate various types of
The blood vessel of type.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the utility model；
Fig. 2 is the side view of the utility model；
Fig. 3 is the top view of the utility model.
Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
In conjunction with shown in Fig. 1 to Fig. 3, a kind of blood vessel separating knife of the utility model comprising one knife is set in 1 front end of knife handle
Piece, the blade in the utility model form the cutter hub 2 of an arc in knife handle front end, and 2 front end of cutter hub forms point of a knife 21, cutter hub two sides
It puts the first edge on a knife or a pair of scissors to form side edge 22.
The connector 3 of one taper first can be set in the front end of knife handle 1, cutter hub 2 is arranged in the front end of connector 3, enables cutter hub 2
End form rod-shaped linkage section 23, linkage section 23 is arranged in 3 front end of connector.Cutter hub 2 can form the flat piece of arc strip
Body, forms side edge 22 at left and right sides of sheet body, and sheet body front end upwards gradually arc bending at the point of a knife 21 for tilting shape.Meanwhile knife handle 1 can
Flat bar is formed, is formed with anti-skid design (not shown) in the grip portions of knife handle, it can more firm grasping.Wherein, knife
The length of handle 1 can be 75-87mm, and the width or diameter of knife handle can be 4.5-5.3mm, and the length of the connector 3 of 1 front end of knife handle can
For 5mm or so.For being about 10mm positioned at the length of rear end linkage section 23 in cutter hub 2, and the length of cutter hub 2 is about 6mm,
Wherein, the length for the point of a knife 21 being upturned can be 1.5 ± 0.1mm, and the thickness of the cutter hub of sheet can be 0.5-0.8mm.
The blood vessel separating knife of the utility model when in use, for blood vessel before the ciliary in eye rectus, passes through blood vessel
After tweezer tweezer lives blood vessel, using the point of a knife 21 of the blood vessel separating knife front end of the utility model, the fascia between blood vessel and muscle is pierced through, is
