Description

A kind of novel high-frequency glass cutting head

Technical field

The utility model relates to medical instruments fields, and in particular to a kind of novel high-frequency glass cutting head.

Background technique

Currently in medical industry, for the vitreum cutting to ocular tissue, typically using vitreous cutter come It completes to cut vitreum and draw, since the vitreum in eyes is in thick, in order to be able to achieve to this sticky Vitreum, machine film and clot of shape etc. gradually blend removal, existing vitreous cutter structure all design it is complex, The high pipeline of the generally double-deck fitness, inner tube high speed reciprocating motion when work, the vitreous cutter of this structure is not only Volume is larger, and inconvenient, and cutting and extraction efficiency are lower, it is difficult to further be miniaturized, can not handle harder lesion Organize (such as lens nucleus), in the course of surgery to vitreum, machine film, crystalline lens and the clot etc. in eyes carry out cutting and Draw less effective.Meanwhile off and on because of its liquid stream, it significantly shakes, is easy to cause causing eye inner tissue to generate therewith Tears retinal or accidental injury.

Therefore, how designing a kind of cutting efficiency height, to draw effect good and can reduce operating time, reduce complication with The high frequency glass cutting head for mitigating patient's pain, is the technical problem that the relevant personnel are urgently to be resolved in industry.

Utility model content

In order to solve the above technical problems, the present apparatus can be in operated eye we have proposed a kind of cutting head of novel high-frequency glass When efficiently cut and aspirate in time the more fragile foreign matter of the tissues such as vitreum, machine film, crystalline lens and clot and part Deng gradually blending removal, in order to siphon away after quickly cutting, the dependence to other instruments is reduced, operating time is reduced, is reduced Complication improves surgical effect, reduces patient's pain.

In order to achieve the above objectives, the technical solution of the utility model is as follows:

A kind of novel high-frequency glass cutting head, including insert structure, the insert structure is including being in single-layer pipeline shape structure The main part and cutting part that portion communicates, the cutting part are set to the front end of main part；

At least one sucker is offered on the cutting part surface, the sucker is communicated with insert structure inner cavity；Sucker mouth Also cutting wire of the rule equipped with plural item, the cutting wire are crossed over above sucker on face, and both ends are fixed on cutting part table On face, and the incision position of cutting part is equipped with indentation at the sucker one side edge, between the indentation includes Every the teeth and tooth socket of setting, and the cutting wire above indentation is respectively positioned on the surface of the tooth socket；

Insert structure is driven in high-frequency vibration source or is moved forward and backward or rotary motion, or carries out front and back and rotation fortune simultaneously When dynamic high-frequency vibration, cutting wire, which vibrates with it and increases amplitude, carries out left and right shearing, In to tissue at indentation Insert structure inner cavity forms subnormal ambient when external negative pressure device works, and vitreum, machine film, crystalline lens and clot are by high frequency vibrating Dynamic cutting wire is shredded, and is flowed at indentation under the action of surface tension and negative-pressure sucking, then be inhaled into In sucker, while after the tissue shredded is inhaled into insert structure inner cavity, enter back into external liquid storage container.

Preferably, the indentation is obliquely installed at edge along cutting part surface to sucker.

Preferably, the indentation is located at the sucker posterior edges, and is arranged close to the main part.

Through the above technical solutions, the utility model on the cutting part surface of the device by offering at least one suction Hole, the sucker are communicated with insert structure inner cavity；The also rule cutting wire that is equipped with plural item on sucker mouth face, the cutting wire across More above sucker, both ends are fixed on cutting part surface, and at the sucker one side edge cutting part incision position Equipped with indentation, the indentation includes spaced teeth and tooth socket, and the cutting above indentation Silk is respectively positioned on the surface of the tooth socket；Insert structure is driven in high-frequency vibration source or is moved forward and backward or rotary motion, or simultaneously When carrying out front and back and rotary motion high-frequency vibration, cutting wire vibrates with it and increases amplitude at indentation to tissue Left and right shearing is carried out, insert structure inner cavity forms subnormal ambient in the work of external negative pressure device, vitreum, machine film, crystalline Body and clot are shredded by the cutting wire of high-frequency vibration, and are flowed to zigzag under the action of surface tension and negative-pressure sucking and lacked After the tissue at mouthful, then being inhaled into sucker, while shredding is inhaled into insert structure inner cavity, external liquid storage is entered back into In container.Not only good cutting effect, and be also conducive to draw, it is promoted and draws effect, reduce the dependence to other instruments, reduction operation Time and replacement instrument number, reduce complication, improve surgical effect, reduce patient's pain, have reached novel in design, structure is closed The purpose of reason and good application effect.
