Description

Intraocular continuous suture needle

Technical Field

The utility model belongs to the technical field of ophthalmic medical instrument's technique and specifically relates to an intraocular continuous suture needle is related to.

Background

The connection part of the iris and the ciliary body is weak in tissue and is easy to break under the action of external force. The iris root is usually injured by eyes, and the iris root with medium size can deform pupils to cause vision disorder; the large iris root is broken, and double pupils can be generated, so that monocular diplopia appears.

The treatment method is to suture the root part of the separated iris by operation, and the traditional operation adopts a method of intermittent suture. For large-area iris root separation, the intermittent suture is very clumsy and troublesome, and simultaneously, a plurality of fiber sutures are consumed, so that the pain of a patient is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an intraocular continuous suture needle, solve the problem that the large tracts of land iris root is disconnected can not sew up fast.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the intraocular continuous suture needle is characterized by comprising a needle handle, a first needle body, a second needle body, a needle head, a wire inlet hole and a wire outlet hole, wherein the needle handle is sequentially connected with the first needle body, the second needle body and the needle head, the first needle body and the second needle body are connected in an obtuse angle, the second needle body is of a hollow structure, the wire inlet hole is formed in the joint of the first needle body and the second needle body, the wire outlet hole is formed in the joint of the second needle body and the needle head, and the wire inlet hole and the wire outlet hole are both positioned on one side far away from the needle handle.

Furthermore, an included angle of 120 degrees is formed between the first needle body and the second needle body.

Further, the needle handle is 5-10 cm in length and 1-5 mm in width, the first needle body is 5-20 mm in length and 0.3-0.8 mm in outer diameter, and the second needle body is 3-8 mm in length, 0.3-0.8 mm in outer diameter and 0.1-0.6 mm in inner diameter.

Further, the needle handle is 10 cm in length and 5 mm in width, the first needle body is 10 mm in length and 0.4 mm in outer diameter, and the second needle body is 5 mm in length, 0.4 mm in outer diameter and 0.2 mm in inner diameter.

To sum up, the utility model discloses a beneficial technological effect does:

(1) can realize continuous suture, reduce operation time and relieve the pain of patients;

(2) the difficulty and the time consumption of the operation are reduced, and the treatment efficiency of the patient is greatly improved.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of a first embodiment of the present invention;

fig. 2 is a schematic view of the sewing process of the present invention, wherein 2a is a first step of continuous sewing, and 2b is a second step of continuous sewing.

Description of reference numerals:

the needle comprises a needle handle 1, a first needle body 2, a second needle body 3, a needle head 4, a wire inlet hole 5 and a wire outlet hole 6.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings and technical solutions needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

The present invention will be further explained with reference to the accompanying drawings.

The continuous suture needle for eyes is composed of a needle handle 1 connected with a first needle body 2, a second needle body 3 and a needle head 4 in sequence.

The first needle body 2 and the second needle body 3 are integrally formed at an angle of 120 degrees.

The middle of the second needle body 3 is a cavity structure for the suture thread to pass through, and the combined positions of the second needle body 3 and the first needle body 2 and the second needle body 3 and the needle head 4 are respectively provided with a wire inlet hole 5 and a wire outlet hole 6.

The needle head is in the shape of a pen point, and the position of the wire outlet hole 6 is positioned on the inner side surface of the shape of the pen point and used for protecting the suture.

For the size of the dimensions, it is preferred according to practical experience: the needle handle is 1 cm long, 5 mm wide, the first needle body is 2 mm long and 10 mm in outer diameter, the second needle body is 3 mm long, the outer diameter is 0.4 mm, and the inner diameter is 0.2 mm.

The suturing process comprises two steps, namely, the step shown in 2a is firstly carried out, a suture thread penetrates into a thread inlet hole, a thread outlet hole penetrates out, a needle is inserted into one side of the eye where the iris is separated and broken, the suture thread penetrates out of the sclera, a certain length is reserved for pulling out the suture thread, the needle head returns along the original path, the suture thread penetrates out again at a certain interval and is reserved to form a lantern ring, the needle head is returned, and the steps are repeated until all parts needing to be sutured are covered; secondly, the step shown in 2b is carried out, the thread head left before is penetrated into the suture thread lantern ring, and the tightness is adjusted; finally, the suture is penetrated out and cut off and knotted with the first thread end, thus completing the continuous suture operation of iris separation.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
