Detailed Description

The utility model is further illustrated in the following, in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present utility model are described by way of illustration only. It is needless to say that the person skilled in the art realizes that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive in scope.

As shown in fig. 1, 3 and 4, an intraocular microsurgical suture remover is used for rapid removal of intraocular microsurgical sutures 10 by means of a microscope or slit lamp. The operation handle 1 is in a round rod shape, and the operation is finer and is implemented by wearing sterile silica gel, rubber gloves and the like, the gloves are stained with disinfectant or liquid medicine, then the operation handle 1 is held relatively smooth, the gloves are easy to slip from hands, the operation difficulty is increased, and therefore anti-slip patterns 2 are generally arranged on the surface of the operation handle 1 to eliminate the defects. One end of the operating handle 1 is connected with a stitch removing connecting rod 3, a stitch removing head 4 which extends outwards is fixedly arranged on the side wall of the end part of the stitch removing connecting rod 3, and when the stitch 10 is removed, the stitch removing head 4 is sent into eyes through the cooperation of the operating handle 1 and the stitch removing connecting rod 3, so that the stitch 10 is lifted and cut off.

Specifically, a stitch removing notch 5 is formed on one side of the stitch removing head 4 facing the operating handle 1, a stitch removing blade 6 is formed at the edge of the stitch removing notch 5, the stitch removing notch 5 is a crescent arc notch, after the stitch 10 enters the stitch removing notch 5, the stitch 10 is lifted up by lifting the operating handle 1, and the stitch 10 is cut off by the stitch removing blade 6 after being stressed.

The line body demolishs head 4 of this embodiment be with the triangle-shaped lamellar body structure of taking out the perpendicular connection of line connecting rod 3, just the outer end that the line body demolishs head 4 sets up to curved anti-stab end 7, anti-stab end 7 is blunt relatively, and the surface is smooth, is difficult to harm the intraocular tissue around the suture 10 after entering the eye, uses safelyr. The two ends of the unraveling notch 5 and the edge of the thread body removing head 4 can be respectively provided with arc-shaped anti-injury transition parts 8 so as to prevent the thread body removing head 4 from scratching the surface of the tissue when being sent under the suture thread 10.

As shown in fig. 4 and 5, the wire body removing head 4 is provided as an arc-shaped sheet body protruding toward a side away from the operating handle 1. When the wire body dismantling head 4 enters the eye, the wide surface of the wire body dismantling head is contacted with the inner surface of the eye, and the wire body dismantling head is similar to lying and feeding the wire body dismantling head, the suture 10 enters the arc-shaped position of the wire body dismantling head in the feeding process, and the outer end of the wire body dismantling head is slightly higher than the arc-shaped position, so that the effect of preventing the suture 10 from falling off is achieved, and the positioning of the suture 10 during cutting is facilitated.

In this embodiment, in order to reduce the occurrence of edges on the parts entering the eyes and scratch the tissues in the eyes, the end of the disconnecting connecting rod 3 is provided with a hemispherical smooth end 9, the surface is smooth and blunt, and the injury preventing effect is remarkable. As shown in fig. 1 and 2, the disconnecting link 3 is either a straight rod arranged in a cylindrical shape or a bent rod with an included angle α of 120-160 °. In this embodiment, the disconnecting connecting rod 3 is preferably configured as a bent rod, which is equivalent to sending the wire body dismantling head 4 to the outside of the operating handle 1 for a distance, so that the wire body dismantling head can be better exposed in the vision of medical staff, and the observation is more convenient when the suture 10 is dismantled.

The use process of the embodiment is as follows: after the surface of a patient is anesthetized, the patient lies flat or sits in a sitting position, a stitch removing doctor adjusts a microscope or a slit lamp to the clearest visual field, holds the operating handle 1, enables the wide surface of the stitch removing head 4 to be in an up-down state, and horizontally moves into eyes, enables the stab preventing end 7 to be aligned below the stitch 10, continuously feeds the stitch 10 into the curved arc of the stitch removing head 4, rotates the operating handle 1 to enable the stitch removing head 4 to stand up, and at the moment, the stitch 10 is just positioned in the stitch removing notch 5, lifts the operating handle 1, cuts the stitch 10 by utilizing the stitch removing blade 6, and then uses stitch removing forceps to forceps out the stitch 10. The curved arc design of the wire body dismantling head 4 and the concave design of the wire dismantling notch 5 have good anti-disengaging effect of the suture 10, so that the repeated matching of the instrument and the suture 10 in eyes is avoided, the wire dismantling efficiency is improved to a certain extent, and the probability of damaging the tissues in eyes is reduced.

The description of the present utility model has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.
