Description

Novel nucleus splitting protection pad

Technical Field

The utility model relates to a surgical instrument, in particular to a novel nucleus splitting protection pad which is applicable to cataract surgery and is convenient to use.

Background

The cataract crystal is composed of crystal capsule, crystal epithelium and crystal fiber with abundant protein content, and the normal crystal is transparent and has no blood vessel, and the nutrition mainly comes from aqueous humor. When the aqueous humor component and the lens capsule permeability are changed and the metabolism is disturbed due to various reasons, the crystal protein is denatured, edema, water cracks and vacuoles appear among fibers, and epithelial cells are proliferated, and then the crystal is changed from transparent to turbid. Whether the location, extent and vision of the crystal opacity are affected or not, it is called cataract.

The cataract ultrasonic emulsification technology is a great achievement of microsurgery, the first ultrasonic emulsification instrument is invented by KELMAN doctors in the United states in 1967 and is used clinically, and then the cataract ultrasonic emulsification technology becomes a world-recognized and early and mature operation mode after 30 years of continuous improvement and perfection by a plurality of ophthalmologists. When in operation, a hyper-breast probe is inserted into a small incision of a cornea or a sclera of an operative eye to break turbid crystalline lens and cortex into chyle, the chyle is sucked out by an aspiration and perfusion system while maintaining the filling of the anterior chamber, and then an artificial lens is implanted to ensure that a patient can see the light. The ultrasonic emulsification technique really realizes the ideal operation of small incision, no pain, short operation time, no need of hospitalization and quick recovery.

Compared with the traditional operation, the cataract ultrasonic emulsification artificial lens implantation has the following advantages:

1. the surgical incision is small, the traditional surgical incision is 8MM, and the surgical incision is smaller than 3 MM;

2. the postoperative reaction is light, the incision is quickly healed, and the vision is quickly and better recovered;

3. the astigmatism after operation is small, and the correction or the control is easier;

4. the operation control degree is better, and the operation is safe and stable;

5. the operation time is short, generally only about 15-30 minutes;

6. the patient does not need to be hospitalized, and can get home after 1 hour of operation;

7. the operation is not performed until the cataract is mature.

In the process of cataract ultrasonic emulsification operation, a nucleus splitting hook is used for splitting the nucleus, so that the ultrasonic emulsification head can conveniently crush the small nucleus. In the existing ultrasonic emulsification operation process, a ultrasonic emulsification head is adopted to suck a core, and a core splitting hook extends into the core to perform cutting. In the process, the posterior capsule under the core cannot be protected at all, the conditions that the posterior capsule is easily punctured by a nucleus splitting hook, the posterior capsule is damaged by an ultrasonic emulsification head, the capsule is damaged after the core slides in the capsule bag and rolls and extrudes, and the like, particularly, a doctor who learns the ultrasonic emulsification technology difficultly masters the safe and skilled nucleus splitting technology in a short time, and the feeling of fear for learning the ultrasonic emulsification operation can be psychologically generated. Therefore, an auxiliary tool for assisting safe nucleus splitting is particularly needed, which can effectively split the nucleus and simultaneously protect the integrity of the posterior capsule, has stable support below the nucleus, facilitates the force application of a nucleus splitting hook, is also suitable for the hard nucleus above IV, and can not finish the nucleus splitting case by using the traditional nucleus splitting method.

Disclosure of Invention

The utility model aims to solve is that in the present conventional cataract ultrasonic emulsification operation, to the doctor of beginner's phacoemulsification technique very much, perhaps the hard core more than the IV utmost point, the tradition is split nuclear ware and phacoemulsification head and is splitting the in-process of nuclear, and the nuclear does not have the support down, and the nuclear slip takes place, and the easy damage of back cyst membrane causes the fracture, and nuclear fragment falls into the vitreous cavity even, causes the unnecessary damage.

The utility model discloses a novel nucleus splitting protection pad, which is characterized in that the protection pad comprises a handle, a connecting rod and a gasket, wherein the handle is a prism, the handle, the connecting rod and the gasket are sequentially connected, and the connecting rod is a cylinder; the packing ring sets up in connecting rod one end, makes the strip through metal wire drawing technology, and the interlude becomes the ellipse circular ring after the fifty percent discount, and two ends all are connected with the connecting rod end, and the ellipse is encircleed middle part, wholly becomes the spoon form, and packing ring length is 20mm, and the diameter is 2mm, and ellipse ring length is 6 mm.

The surface of the elliptical ring is provided with a tooth-shaped fine groove so as to increase the friction force between the bottom of the nucleus and the gasket and prevent the nucleus from sliding.

The handle on parallel be provided with several recesses, the recess is perpendicular with the handle axis, through setting up the recess, frictional force when can effectively increase and grip.

The connecting rod length be no longer than 20mm, suitably reduce connecting rod length, can increase the intensity of connecting rod self, avoid at the operation in-process, connecting rod atress deformation adopts straight banding connecting rod simultaneously, can reduce the mistake and bump the condition and take place.

The utility model discloses a novel split nucleus protection pad, simple structure, the design science, convenient to use makes it can satisfy the operation requirement, reduces connecting rod length, effectively increases intensity, can also stop the mistake and bump the condition and take place, increases the recess on the handle simultaneously, has improved the frictional force of handle, the operation in-process of being convenient for grips the handle.

Detailed Description

Example 1: a novel nucleus splitting protection pad comprises a handle 1, a connecting rod 2 and a gasket 3, wherein the handle 1 is a prism, the handle 1, the connecting rod 2 and the gasket 3 are sequentially connected, and the connecting rod 2 is a cylinder; the packing ring 3 sets up in connecting rod 2 one end, makes the strip through metal wire drawing technology, and the interlude becomes the ellipse circular ring form after the fifty percent discount, and two ends all are connected with connecting rod 2 ends, and the ellipse is encircleed middle part, wholly becomes the spoon form, and 3 length of packing ring are 20mm, and the diameter is 2mm, and ellipse ring length is 6 mm. The surface of the oval ring is provided with fine grooves in the form of teeth so as to increase the friction between the bottom of the nucleus and the washer 3 and prevent the nucleus from sliding. A plurality of grooves are arranged on the handle 1 in parallel and are perpendicular to the axis of the handle 1, and friction force during holding can be effectively increased by arranging the grooves. 2 length of connecting rod is no longer than 20mm, suitably reduces 2 length of connecting rod, can increase the intensity of 2 self of connecting rod, avoids at the operation in-process, and 2 atress deformations of connecting rod adopt straight banding connecting rod 2 simultaneously, can reduce the mistake and bump the condition and take place.
