The labels in the figure are: 1-surgical needle body, 2-U-shaped groove, 21-first side, 22-second side, 23-elastic guide strip, 24-protective strip, 25-guide opening and 26-inner cavity.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Examples
Fig. 1 shows the structure schematic diagram of the threading-free operation needle in the embodiment of the present invention, fig. 2 shows the structure schematic diagram of the embodiment of the present invention enlarged by a in fig. 1, the threading-free operation needle includes an operation needle body 1, the tail of the operation needle body 1 is provided with a U-shaped groove 2, a first side 21 of the U-shaped groove 2 is fixedly connected with an elastic lead line 23, and the outer end of a second side 22 of the U-shaped groove 2 and the elastic lead line 23 form an acute angle of a guide port 25. The surgical needle body 1 is arc-shaped, the arc-shaped surgical needle body 1 is easier to perform suture operation, the second side 22 of the U-shaped groove 2 and the elastic lead strip 23 form an acute-angle guide opening 25, and the elastic lead strip 23 is contacted with the second side 22 of the U-shaped groove 2. When threading, the wire is straightened, then the wire enters the inner cavity 26 of the U-shaped groove 2 through the guide opening 25, the inner cavity 26 of the U-shaped groove 2 is a cavity formed by the inner side of the U-shaped groove 2 and the elastic leading line strip 23, and the barb at the acute angle formed by the first side 21 of the inner side of the U-shaped groove 2 and the elastic leading line strip 23 can pull the wire to prevent the wire from falling off.
The second side 22 of the U-shaped groove 2 is fixedly connected with a guard bar 24, and the guard bar 24 is located below the elastic lead bar 23. Specifically, the outer end of the second side 22 of the U-shaped groove 2 forms an obtuse angle with the protection strip 24, and the protection strip 24 guides the wire into the inner cavity 26 of the U-shaped groove 2 when the wire enters the U-shaped groove 2 through the guide opening 25. When the threading-free surgical needle is used for surgical suture, the protective strip 24 can prevent the thread from sliding out of the U-shaped groove 2 through the guide port 25, and has good practicability.
The surgical needle body 1 is made of austenitic stainless steel materials, and can penetrate through the hardness of tissues and bear the suture strength for a plurality of times.
The surgical needle body 1 is coated with a black matt coating which does not reflect light under a black endoscope, has clear visual field and is convenient to operate with a needle.
The threading-free surgical needle provided by the embodiment of the utility model has the advantages that the elastic lead strip 23 is arranged on the U-shaped groove 2, the elastic lead strip 23 and the second side 22 of the U-shaped groove 2 form the guide port 25 for fast threading, the threading difficulty is reduced, the elastic lead strip 23 can block the gap of the U-shaped groove 2 to pull the thread, the thread can be normally sewn, and the threading efficiency is improved; the U-shaped groove 2 is provided with a protective strip 24 which protects the guide opening 25 to prevent the thread from threading the surgical needle from the falling surface of the guide opening 25 during sewing, and the practicability is improved.
The embodiments of the present invention have been described in detail, and the principle and the implementation of the present invention are explained herein by using specific embodiments, and the above description of the embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
