Description

A kind of operation small incision cataract incision

Technical field

The utility model relates to technical field of surgical instruments, specially a kind of operation small incision cataract incision.

Background technique

Although phacoemulsification technique is increasingly widespread, manual small incision cataract surgery still has there are advantage, It is still one of main modus operandi of basic hospital cataract, general manual small incision incision of cataract length is 6 millimeters, hand Method small incision cataract surgery, operation safety is high, but Surgical induced astigmatisn is big compared with cataract surgery, how that gimmick is small The notch of incision cataract surgery is made smaller, cataract operation is completed by smaller notch, than U.S. cataract ultrasonic emulsification Operation, in view of this, we devise gimmick miniature incision incision of cataract drag hook, this incision can stretching scleral tunnel cut Mouthful, while drawing subduction can be led to, cataract core block is facilitated to give birth to outside eye, realize that 3-4 millimeters of small fixation through scleral tunnels incision are completed Cataract operation.

Utility model content

The purpose of this utility model is to provide a kind of operation small incision cataract incisions, to solve above-mentioned background skill The relatively large problem of existing existing manual small incision cataract surgery notch is proposed in art.

To achieve the above object, the utility model provides the following technical solutions: a kind of operation small incision cataract notch drawing The upper end of hook, including handle cylinder, the handle cylinder is fixedly connected with the lower end of conical nose, the upper end of the conical nose It is fixedly connected with the lower end of connector, the upper end of the connector is fixedly connected with one end of hook end, the other end of the hook end It is provided with hook end head.

Preferably, the handle cylinder, conical nose, connector and hook end are all made of stainless steel or titanium alloy is made, And handle cylinder, conical nose, connector and hook end pass through welded connecting.

Preferably, the cylindrical body that the handle cylinder is 3 millimeters of diameter, and the length of handle cylinder is 100 millimeters.

Preferably, the connector be 0.3 millimeter of diameter rigidity cylindrical body and handle cylinder X-axis, Y-axis respectively at 135 ° of angles, and the length of connector is 10 millimeters.

Preferably, the hook end is 0.3 millimeter wide, thick 0.1 millimeter of bent bodies, and hook end and connector are in X-axis, Y-axis point Not at 135 ° of angles, and the length of hook end is 2 millimeters, 1 millimeter of gap.

Preferably, the hook end head is arc-shaped.

It is and existing compared with prior art, the utility model has the beneficial effects that the operation small incision cataract incision There is drag hook to compare and be made that very big improvement in structure, by the design of incision, 3-4 millimeters of sclera tunnels can be passed through Road notch completes cataract operation, performs the operation simple and easy, opens lesser notch sufficiently, draw out larger crystal nuclear block, avoid Big notch brings more complication, while can control the eyeball direction of patient, convenient to operate to disoperative patient, helps Hand allows patient's subduction while pulling eyeball, and operating doctor is facilitated smoothly to draw out cataract core block, particularly suitable base doctor Institute, the cataract ultrasonic emulsification instrument device for avoiding purchase expensive, can also implement the cataract operation of high quality.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of operation small incision cataract incision, Including handle cylinder 1, conical nose 2, connector 3, hook end 4 and hook end head 5, upper end and the conical nose 2 of handle cylinder 1 Lower end is fixedly connected, and the upper end of conical nose 2 is fixedly connected with the lower end of connector 3, the upper end of connector 3 and the one of hook end 4 End is fixedly connected, and the other end of hook end 4 is provided with hook end head 5；

Further, handle cylinder 1, conical nose 2, connector 3 and hook end 4 are all made of stainless steel or titanium alloy system At, and handle cylinder 1, conical nose 2, connector 3 and hook end 4 improve the service life of incision by being welded to connect；

Further, the cylindrical body that handle cylinder 1 is 3 millimeters of diameter, and the length of handle cylinder 1 is 100 millimeters, is convenient for The grasping of user；

Further, connector 3 be 0.3 millimeter of diameter rigidity cylindrical body and handle cylinder 1 X-axis, Y-axis respectively at 135 ° of angles, and the length of connector 3 is 10 millimeters, avoids incision block vision；

Further, hook end 4 is 0.3 millimeter wide, thick 0.1 millimeter of bent bodies, and hook end 4 and connector 3 are in X-axis, Y-axis point Not at 135 ° of angles, and the length of hook end 4 is 2 millimeters, 1 millimeter of gap, it is ensured that can complete cataract in small fixation through scleral tunnels incision Operation；

Further, hook end head 5 is arc-shaped, and hook end head 5 is avoided to scratch eyes of patients.

Working principle: when using operation small incision cataract incision, first to handle cylinder before operation carries out 1, conical nose 2, connector 3 and hook end 4 carry out disinfection, and when being performed the operation, assistant holds the handle cylinder 1 of incision, It is opened by the stretching that will dehisce of hook end 4, while drawing subduction help and drawing out crystal nuclear, instrument does not block operating field, thus not Observation of the operator patient to operative region is interfered, incision uses completion.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
