Description

Suction perfusion needle head for preventing damage caused by suction of capsule membrane

Technical Field

The utility model relates to the field of medical appliances, in particular to a suction perfusion needle for absorbing emulsion in cataract surgery to prevent damage caused by broken absorption of a capsule membrane.

Background

During cataract operation, the turbid crystalline lens needs to be removed after ultrasonic emulsification, and then an artificial crystalline lens is implanted. After ultrasonic emulsification and suction of lens nucleus and lens cortex, colored liquid medicine is injected into the capsular bag to act for a certain time and then suction is carried out. When the substances in the capsular bag are sucked, due to the problems of sight line and angle, the needle point part of the suction needle is easy to touch the wall of the posterior capsular sac, so that the liquid in the capsular bag permeates into the vitreous body, and the surgical complications of poor toxicity of cornea and retina are caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses absorb the problem of bumping the back cyst wall easily with the needle point of suction needle after phacoemulsification among the prior art, provide a suction perfusion syringe needle that prevents that the damage is inhaled to the cyst membrane, through set up at the needle point position and separate the cowl who keeps off the usefulness to avoid needle point and the direct touch contact of back cyst membrane and puncture back cyst membrane position.

The utility model aims at realizing like this, a prevent that cyst membrane from inhaling suction perfusion syringe needle of broken damage, include suction needle pipe and perfusion needle pipe, suction needle pipe and perfusion needle pipe one end are connected the suction respectively and are connected and are connect and fill the joint, suction needle pipe and the main part pipe part that fills the needle pipe laminate side by side, its characterized in that, the pipe wall at the terminal suction mouth position of suction needle pipe and perfusion needle pipe is pasted outward and is equipped with cowl, cowl is connected with the pipe wall laminating of suction needle pipe and perfusion needle pipe along needle pipe length direction's partly, and cowl's another part is the arc extension and stretches out to pitch arc extending direction orientation suction needle pipe and the one side of filling the needle.

The utility model discloses a prevent that suction of rupture of membranes of capsules damage fills syringe needle, when the suction operation, when the needle point stretched into the operation of sucking in the eye lens sack, direct contact in cowl and the bag had avoided the needle point to contact the rupture of capsules wall to the rupture of capsules wall has effectively been avoided.

Furthermore, the radian of the arc-shaped baffle is adapted to the shape of the posterior capsule wall of the eyes of the human body.

Furthermore, the arc-shaped baffle is rectangular after being unfolded, and four corners of the arc-shaped baffle are smooth.

In order to prevent the suction opening from being blocked, the needle tip pipe orifices of the suction needle pipe and the perfusion needle pipe are oblique incisions, the oblique incisions of the two needle pipes face towards the same direction, and the arc-shaped baffle is attached to the back side of the oblique incisions.

For the convenience of operation, the ends of the tube body parts of the suction needle tube and the perfusion needle tube are in arc-shaped bending.

In order to be convenient for repeated use, the suction needle tube, the perfusion needle tube and the arc-shaped baffle are made of medical-grade stainless steel materials.

Drawings

Fig. 1 is a front view of the suction perfusion needle head for preventing the damage of the sucking and breaking of the capsule membrane.

Fig. 2 is a left side view of fig. 1.

Wherein, 1, the needle tube is sucked; 2, filling a needle tube; 3, sucking the needle head; 4, filling a needle head; 5 arc-shaped baffle plates.

Detailed Description

Fig. 1 and fig. 2 show that the utility model discloses a prevent that capsule from inhaling suction perfusion syringe needle of broken damage, including suction needle 1 and perfusion needle 2, suction needle 1 and perfusion needle 2 one end connect respectively suction joint 3 and perfusion joint 4, suction needle 1 and perfusion needle 2's main part pipe part laminates side by side, the pipe wall of the terminal suction mouth position of suction needle 1 and perfusion needle 2 pastes outward and is equipped with cowl 5, cowl 5 is connected with suction needle 1 and perfusion needle 2's pipe wall laminating along the partly of needle tube length direction, cowl 5's another part is the arc extension and stretches out, and the arc extending direction is towards one side of suction needle and perfusion needle; for the convenience of operation, the ends of the tube body parts of the suction needle tube 1 and the irrigation needle tube 2 are arcuately curved.

In order to facilitate the attachment of the arc-shaped baffle 5 and the posterior capsule wall in the operation, the radian of the arc-shaped baffle 5 is adapted to the shape of the posterior capsule wall of the human eyes; the arc-shaped baffle 5 is rectangular after being unfolded, and four corners of the arc-shaped baffle are smooth.

In order to prevent the suction opening from being blocked, the needle tip end mouths of the suction needle tube 1 and the perfusion needle tube 2 are oblique openings, the oblique openings of the two needle tubes face the same direction, and an arc-shaped baffle plate 5 is attached to the back side of the oblique openings.

In order to be convenient for repeated use, the suction needle tube 1, the perfusion needle tube 2, the suction needle head 3, the perfusion needle head 4 and the arc-shaped baffle plate 5 are made of medical-grade stainless steel materials, so that the needle head can be reused after being sterilized after each operation.

The utility model discloses a prevent that cyst membrane from inhaling the suction filling needle of breaking the damage, during the operation, after phaco nucleus and crystalline cortex were inhaled in the phacoemulsification, inject into coloured liquid medicine in the bag, after acting on certain time, will the utility model discloses a prevent that cyst membrane from inhaling the suction filling needle of breaking the damage and insert the sack from operation incision passageway in, cowl and the back cyst membrane wall laminating contact of bag this moment, avoided the needle point to contact the cyst membrane wall, inject into the perfusate on one side and aspirate coloured liquid, until the liquid medicine is inhaled completely, effectively avoided the back cyst membrane wall to be punctured.
