Abstract
The invention discloses a kind of new and effective crystalline lenses and the dual-purpose cutting head of vitreum, including outer tube and inner tube, inner tube is set in outer tube, outer tube front end is cecum, at least two outer tube suckers are offered on the side wall of outer tube front end, wherein front end outer tube sucker length-width ratio is at least 1.5:1, inner tube is the hollow pipe of front opening, it is corresponding on the side wall of inner tube front end to offer at least one inner tube sucker, inner tube sucker outer edge and outer tube sucker inward flange are tangent, and outer tube sucker and inner tube sucker rear end outwardly protrude to form wedge angle.Vitreum can collect to sharp corner in cutting process, and in the design production process of cutting head, it is also easier to set closer contact point for the sharp corner of sucker, so being easier to thoroughly cut off vitreum, the front end that the cutting head not only passes through inner tube can be cut, it increases sucker on side wall simultaneously to be cut, cutting efficiency greatly improves, and can cut harder crystalline lens and very soft vitreum simultaneously.
Description
Technical field
The present invention relates to clinical treatment utensils, and in particular to a kind of new and effective crystalline lens and the dual-purpose cutting of vitreum
Head.
Background technique
In medical industry, tissue cutting now is generally completed using scalpel cutting operation mode,
But this mode wound face is big, and patient is more painful, and easily leaves scar etc., and the organ having on human body is more fine, also not
Easily completed by the way of scalpel cutting.Cutting tissue under such as laparoscope often with micro-scissors or stings cutter, still
The tissue mass of removal is very limited.It is for another example cut for the vitreum to ocular tissue, since the vitreum in eyes is in sticky
Shape is gradually blended removal to this thick vitreum, machine film and clot etc. to be able to achieve, is exactly cut using vitreum
Cutter is completed to cut vitreum and draw, but it includes interior that the cutting header structure of existing vitreous cutter, which is,
Pipe and outer tube offer sucker on outer tube, and inner tube front end is connected to outer tube, is moved forward and backward by inner tube by the glass at sucker
Body, cutting siphon away, and the cutting head of this structure only leans on the front end of inner tube to cut, and cutting efficiency is lower, and due to inner tube and outside
It manages and is not easy to guarantee to be bonded entire cut surface is all very close, due to the characteristic of vitreum, this cutting header structure is not
Easily cutting vitreum.Cutting head outer tube aperture length-width ratio is essentially 1:1 at present, and harder crystalline lens is difficult to be inhaled into lumen, general
It is extremely low or substantially invalid that logical cutting head handles harder crystalline lens efficiency.
Therefore, a kind of easily cutting vitreum and the high cutting head of cutting efficiency how are designed, while can also be taken into account to crystalline substance
The cutting of shape body is the technical problem that the relevant personnel are urgently to be resolved in industry.
Summary of the invention
The purpose of the present invention is to provide a kind of new and effective crystalline lens and the dual-purpose cutting head of vitreum, cutting head cuttings
It is high-efficient, it easily is switched off vitreum, while can also take into account to lenticular cutting, using effect is good.
In order to achieve the above objectives, technical scheme is as follows:
A kind of new and effective crystalline lens and the dual-purpose cutting head of vitreum, which is characterized in that including outer tube and inner tube, it is described in
Pipe is set in the outer tube, and the outer tube front end is cecum, offers at least two outer tubes on the side wall of the outer tube front end
Sucker, wherein front end outer tube sucker length-width ratio is at least 1.5:1, and said inner tube is the hollow pipe of front opening, said inner tube
It is corresponding on the side wall of front end to offer at least one inner tube sucker, said inner tube sucker outer edge and the outer tube sucker inner edge
Edge is tangent, and the outer tube sucker and inner tube sucker rear end outwardly protrude to form wedge angle.
Preferably, the outer tube sucker and inner tube sucker subcircular, the hole periphery corresponding to 210 degree or more central angles are circle
Other peripheries on shape periphery, hole are connect with circumferential edge, and are outwardly protruded and to be formed wedge angle.
Preferably, the outer tube sucker and inner tube sucker are closely rectangular, and the hole periphery corresponding to 210 degree or more central angles is side
Other peripheries on shape periphery, hole are connect with squared perimeter, and are outwardly protruded and to be formed wedge angle.
Preferably, other peripheries of the outer tube sucker and inner tube sucker are arcuate perimeter.
Preferably, the outer tube sucker and inner tube sucker wedge angle are towards rear end.
Preferably, certain radian is bent to the side surface direction for offering inner tube sucker at the 1-2mm of said inner tube front end.
Preferably, the distance between described outer tube sucker is the fixed value less than its own length.
Through the above technical solution compared with prior art, beneficial effects of the present invention are as follows: inner tube rear end is equipped with negative
Pressure device, vitreum are inhaled into inner tube from sucker, and inner tube moves forward and backward, and can vitreum be cut off and be siphoned away.Due to sucker
There is wedge angle, so vitreum can all collect to sharp corner, big in this way since the sharp corner area of sucker becomes smaller when cutting every time
It is big to reduce cutting area, it is easy to cut, and in the design production process of cutting head, it is also easier to the sharp corner of sucker
It is set as closer contact point, such cut point can be even closer, so easier to cut, which not only passes through described
The front end of inner tube can be cut, while being increased sucker on side wall and being cut, and interrupt liquid stream not, cutting efficiency is significantly
Raising, and harder crystalline lens and very soft vitreum can be cut simultaneously.
