Technical Field

The utility model belongs to the field of medical equipment, concretely relates to rotation type capsule membrane is cut.

Background

In cataract surgery, when cutting capsular sac or organizing the capsular sac, the surgeon generally extends the capsular sac scissors from the incision to the edge along the pupil to cut the capsular sac open. Because the pupil is round, when the positions close to the two sides of the incision are spliced, a doctor can cut the pupil into an arc shape fitting the edge of the pupil by adjusting the angle of the capsular scissors; however, when the inner side of the scissors is opposite to the incision, the width of the incision is limited, and the adjustment angle of the capsular scissors is limited, so that the opposite side of the incision cannot cut an arc shape attached to the edge of the pupil, and most of the capsular edges cut in the existing operation process are uneven in saw-tooth shape, which is not beneficial to subsequent operation.

In order to solve the shortcoming that exists among the above-mentioned prior art, the utility model provides a rotation type capsule is cut, concrete scheme is as follows:

including two articulated scissors bodies, its characterized in that: the working ends of the two scissors bodies are respectively hinged with an arc-shaped blade, the cutting edges of the two blades are arranged oppositely, and the rotating planes of the blades are perpendicular to the moving plane of the scissors bodies.

Furthermore, the working end of the scissors body is bent outwards for a certain distance to form two parallel rod bodies, and the blade is arranged between the two rod bodies; the tail ends of the two rod bodies are provided with opposite shaft sleeves, one side of the blade is connected with a rotating shaft matched with the shaft sleeves, and the blade is connected with the rod bodies through the rotating shaft and the shaft sleeves.

Furthermore, an operating rod is hinged to one side, located on the rotating shaft, of the blade.

Furthermore, an axial cavity is formed in the scissors body, the operating rod extends out of the scissors body through the cavity, the operating rod is connected with the blades through a connecting rod, and two ends of the connecting rod are hinged with the operating rod and the blades.

Furthermore, be equipped with the screens on the action bars, the end of holding of scissors body still be equipped with the screens cooperation just has reset function's jack catch, be equipped with on the action bars with the scale that the screens corresponds.

The utility model provides a pair of rotation type cyst membrane is cut, simple structure, convenient operation can be under the limited prerequisite of incision width, and the edge is a smooth arc when guaranteeing to cut the cyst membrane of anterior chamber internal and incision relative position, more is favorable to subsequent implantation operation.

Detailed Description

In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.

Example 1

With reference to fig. 1-3, the utility model discloses a conjunctival flap material taking device, including two articulated scissors bodies 1, the working end of two scissors bodies 1 respectively articulates has an arc blade 2, and the cutting edge mutual disposition of two blades 2, blade 2 pivoted plane and the plane mutually perpendicular of scissors body 1 motion.

The working end of the scissors body 1 is bent outwards for a certain distance to form two parallel rod bodies 101, and the blade 2 is arranged between the two rod bodies 101; the tail ends of the two rod bodies 101 are provided with opposite shaft sleeves 102, one side of the blade 2 is connected with a rotating shaft 201 matched with the shaft sleeves 102, and the blade 2 is connected with the rod bodies 101 through the rotating shaft 201 and the shaft sleeves 102.

The working principle of the utility model is as follows:

when the positions close to two sides of the cut are spliced, the two blades are operated to rotate to the state shown in figure 2, and then the two scissors bodies are normally operated to drive the blades to move to cut the capsular sac along the arc;

when the cutting inner side is opposite to the cut, the two blades are operated to rotate to the state shown in fig. 3, and then the two scissors bodies are normally operated to drive the blades to move so as to cut the edge of the inner side of the cyst membrane into an arc shape corresponding to the blades.

Example 2

With reference to fig. 4 and 5, the present embodiment differs from embodiment 1 in that: an operating rod 3 is hinged to one side of the blade 2, which is positioned on the rotating shaft 201.

Axial cavity 4 has been formed to scissors body 1 internal shaping, and the action bars 3 stretches out scissors body 1 through cavity 4, is connected through connecting rod 5 between action bars 3 and the blade 2, and the both ends of connecting rod 5 are all articulated with action bars 3 and blade 2.

The operating rod 3 is provided with a clamping position 301, the holding end of the scissors body 1 is also provided with a clamping jaw 103 which is matched with the clamping position 301 and has a reset function, and the operating rod 3 is provided with scales corresponding to the clamping position 301.

Compared with the embodiment 1, the blade angle of the embodiment can be adjusted by pushing the operating rods, the claw is used for extending into the angle of the clamping fixed blade, and the two blade angles are ensured to correspond by comparing scales on the two operating rods in actual operation.

Example 3

As another embodiment, the blade and the scissors body are hinged by a structure with a self-locking function, the structure comprises a chuck arranged around a rotating shaft, a plurality of clamping grooves are arranged on the chuck, a movable disc corresponding to the chuck is arranged on the blade or the scissors body, and spring clamping columns (not shown in the attached drawings) matched with the clamping grooves are arranged on the movable disc; adopt above-mentioned structure articulated between blade and the scissors body for the angle between blade and the scissors body can be adjusted according to the user demand, guarantees the relatively stable of this angle when performing the operation simultaneously.

In summary, the preferred embodiments of the present invention are only examples, and the scope of the present invention is not limited thereto, and all equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope covered by the present invention.
