Description

Scleral plate incision scalpel

Technical Field

The utility model belongs to the field of ophthalmic surgical instruments, in particular to a special scalpel for preparing scleral plate incision.

Background

The scleral plate layer incision is an operation incision with a half scleral depth and a valve formed on the sclera, has better incision tightness, and has important application in the operations of trabeculectomy, intraocular lens scleral layer fixation and the like.

The current sclera plate incision is made by using a metal tunnel knife, needs to be pushed along the tangent direction of the eyeball wall after the sclera plate is firstly incised according to the clinical experience of an operator, and has higher requirements on the operator and longer learning curve. The scleral lamina incision is not deep enough to cause the scleral flap to break easily, while the scleral lamina incision is too deep to increase the risk of perforation of the eyeball, and no effective surgical instrument is available at present to manufacture the scleral lamina incision in a more standardized way.

Disclosure of Invention

The utility model aims at providing a scleral plate layer incision scalpel further simplifies the notched preparation of scleral plate layer, improves the security and the standardization of operation.

The utility model aims at realizing through the following technical scheme: the utility model provides a scleral plate incision scalpel which characterized in that: comprises a cutter body, a side wing and a cut protection baffle; the cutter body is shovel-shaped and comprises a front-end blade and a rear-end cutter handle, a cutting edge is arranged at the front end of the blade, the side wings are perpendicular to the blade and symmetrically arranged on two sides of the blade along the longitudinal axis of the blade, the upper ends of the side wings are parallel to the blade and are provided with cut protection baffles, the cut protection baffles are located on the outer sides of the blade, and the front ends of the cut protection baffles are upward rolling curved surfaces.

The surface of the blade is a non-reflective surface.

The central axis of the knife handle and the blade form an included angle of 145 degrees.

The knife handle is connected with the blade through a coaxial connecting part.

The utility model has the advantages that:

1. the shovel blade type structure with the lateral wings on the two sides limits the cutting depth and plays a role in flap formation in the process of cutting the sclera, so that the process of making the incision of the scleral plate layer is simpler, more convenient and more standardized.

2. Through using this scleral lamina incision scalpel, the doctor can swiftly, make the scleral lamina incision of standard size safely, further reduce the risk of scleral lamina surgical incision preparation, improve the standardization level of operation.

Detailed Description

The embodiment is as follows: a scleral lamina incision scalpel comprises a scalpel body 1, a side wing 5 and an incision protection baffle 4; the cutter body 1 is shovel-shaped and consists of a front-end blade and a rear-end cutter handle 6, the blade is made of 4Cr13 stainless steel materials, the surface of the blade is a non-reflective surface, the width of the blade is 2mm, the front end of the blade is provided with a cutting edge 2, the cutting edge 2 is designed to be an upper inclined surface, the cross section of the side wing 5 is inverted L-shaped and perpendicular to the blade, the side wing is symmetrically arranged on two sides of the blade along the longitudinal axis of the blade, the height of the side wing is 0.3mm, the length of the side wing is 2mm, the front edge of the side wing 5 is 2.4mm away from the cutting edge, a notch protection baffle 4 at the upper end of the side wing 5 is positioned on the outer side of the blade, the width of the wing is 1mm, and the front end of the notch protection baffle 4 is an upward rolling curved surface; the handle 6 is made of PVC material and is connected with the blade through the coaxial connecting part 3, and the central axis of the handle and the plane of the blade form an included angle of 145 degrees

The design has the shovel blade type structure of two side flanks, limits the cutting depth and forms the flap effect in the process of cutting the sclera, so that the process of making the scleral slab incision is simpler and more convenient and standardized.

When making the sclera plate layer incision, a doctor holds the scalpel, firstly adjusts the angle of the scalpel handle to ensure that the cutting edge is perpendicular to the sclera of a target area, the knife handle is punctured to form the depth of the sclera incision to the contact incision protection baffle plate in a manner of being perpendicular to the sclera surface, then adjusts the angle of the scalpel handle to ensure that the plane of the scalpel body is parallel to the tangential direction of the sclera of the cutting part, and the scalpel is withdrawn after the incision length of the sclera reaches the length of the side wing, namely the sclera plate layer incision is made.
