Description

Technical Field

[0001] This utility model relates to the field of suture needle technology, specifically a medical suture needle. Background Technology

[0002] Suture needles are commonly used suturing instruments in medical surgery. Existing curved suture needles generally have a sharpened edge at one end and an eye at the other. During use, the suture thread needs to be passed through the eye and tied, and then the needle tip is manipulated to repeatedly puncture and suture the tissue. Because this type of suture needle requires repeated punctures, it necessitates repeated needle withdrawals, which can lead to tissue depression. Furthermore, the suture thread tying after passing through the eye is extremely cumbersome, significantly reducing suturing efficiency. Therefore, we propose a new medical suture needle. Utility Model Content

[0003] The purpose of this invention is to provide a medical suture needle to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a medical suture needle, comprising a needle shaft, wherein a first needle eye and a second needle eye are provided through the waist of the needle shaft from the inside to the outside, and a first needle tip and a second needle tip are respectively provided at the upper and lower ends of the needle shaft, and the connection between the first needle tip and the second needle tip and the needle shaft is streamlined, and side blades are provided on the front and rear sides of the first needle tip and the second needle tip, and the side blades are arc-shaped near the position of the needle shaft.

[0005] Preferably, the needle bar is a solid alloy steel needle with an outer diameter of 1.1 mm and a length of 10 cm.

[0006] Preferably, the first and second needle holes are located on the section of the needle bar near the second needle tip, and the distance between the first and second needle holes is less than 10 mm.

[0007] Preferably, the outer ends of the first and second needle tips are sharp, the sides are flat, and the maximum width is equal to the outer diameter of the needle shaft.

[0008] Preferably, the side blade extends from the tips of the first and second needle tips to their junction with the needle shaft.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This medical suture needle, by setting a first needle tip and a second needle tip at both ends of the needle bar, allows suturing operations to be performed at both ends without the need for one end to puncture back and forth. Both ends are sharp and can pass back and forth through the tissue without needing to withdraw the needle, reducing tissue depression caused by needle withdrawal and re-entry. At the same time, both the first and second needle tips have side blades, which can improve the puncture sharpness of the needle tip, reduce puncture resistance, and improve the smoothness of suturing. By setting a first needle eye and a second needle eye at the waist of the needle bar, the friction between the suture and the needle eye can be increased by increasing the complexity of the path of the suture through the first and second needle eyes, thereby achieving the effect of locking the suture position. This allows the suture to be automatically locked without the need for knotting, improving suturing efficiency. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2This utility model provides a technical solution: a medical suture needle, including a needle shaft 1, which is a solid alloy steel needle with an outer diameter of 1.1 mm and a length of 10 cm. The needle shaft 1 is initially straight and can be manually bent into a V-shape or an arc shape. A first needle eye 5 and a second needle eye 6 are provided through the waist of the needle shaft 1 from the inside to the outside. The suture thread passes through the first needle eye 5 and the second needle eye 6 in sequence. The suture thread is locked by the large friction between the bend after passing through the needle eye and the two needle eyes, eliminating the need for knotting before suturing. The first needle eye 5 and the second needle eye 6 are located on the section of the needle shaft 1 near the second needle tip 3, and the distance between the first needle eye 5 and the second needle eye 6 is less than 10 mm. When the suture thread passes through the first needle eye 5 and the second needle eye 6 in sequence, there will be a bend or break at the connection between them. This increases the complexity of the suture path and greatly increases the risk of breakage between the suture thread and the needle eye. The friction between them can meet the locking requirements of the suture line position during suturing. The needle bar 1 has a first needle tip 2 and a second needle tip 3 at its upper and lower ends, respectively. The connection between the first needle tip 2 and the second needle tip 3 and the needle bar 1 is streamlined. The outer ends of the first needle tip 2 and the second needle tip 3 are sharp, and the sides are flat. The maximum width is equal to the outer diameter of the needle bar 1. The first needle tip 2 and the second needle tip 3 set at both ends of the needle bar 1 can be used for suturing operations at both ends. No one end needs to puncture back and forth. The sharp ends can pass back and forth in the tissue without the need to withdraw the needle. This reduces the tissue depression caused by withdrawing and re-entering the needle. The first needle tip 2 and the second needle tip 3 both have side blades 4 on their front and rear sides. The side blades 4 are arc-shaped near the needle bar 1. The side blades 4 are opened from the tips of the first needle tip 2 and the second needle tip 3 to their connection with the needle bar 1. The opening of the side blades 4 can improve the puncture sharpness of the needle tip, reduce puncture resistance, and improve the smoothness of suturing.

[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
