The suture needle of the present invention is a fast, non-wearing medical suture needle, which can greatly save the needle threading time, and does not require good eyesight and hand-eye coordination, thereby speeding up the operation and reducing the patient's pain.

Description

Non-wearing medical suture needle

technical field

The invention belongs to medical instruments, in particular to a non-piercing medical suture needle, which is an instrument used for suturing during surgical operations.

Background technique

The suture needle is one of the indispensable instruments in the surgical operation process. At present, the pinhole of the suture needle commonly used in China is a rectangular pinhole. When using it, the surgeon or nurse needs to pass the suture thread through the pinhole, turn back the thread, and turn it back. The thread card can only be used after it is fixed on the needle holder. There are the following deficiencies: ①The pinhole of the suture needle is very small, and the thick suture often cannot pass through the small suture needle hole; ②When the suture tip is bifurcated, it is difficult to penetrate the needle hole; ③The operator or nurse is required to have Good eyesight and hand-eye coordination are required to thread the needle accurately and quickly. Common suture needles are time-consuming and labor-intensive due to the long time of threading the needles, which affects the progress of the operation.

Contents of the invention

In order to overcome the above-mentioned shortcomings and better improve the operation efficiency, the purpose of the present invention is to invent a fast, non-wearing medical suture needle.

The purpose of the present invention is achieved in this way, a non-wearing medical suture needle, including a curved needle body, characterized in that: one end of the curved needle body is pointed, and the other end forms a U-shaped groove, and the upper end of the U-shaped groove is open, There are two surfaces extending inward at the left and right ends respectively, and the two surfaces interact in parallel. There is a gap between the two interactive surfaces, and the gap is less than or equal to the diameter of the threading wire.

The two mutual surfaces and the bottom surface of the U-shaped groove form an oval line hole.

The outer sides of the two mutual faces form a downwardly angled wire edge.

The inner sides of the two mutual surfaces form an upwardly curved retaining edge.

The arc diameter of the sewing needle is 14mm, the length of the needle body is 22±1mm, the needle tip is 0.3mm, and the needle tail is 1.2mm.

The advantages of the present invention are: one end of the curved needle body is sharp, the other end forms a U-shaped groove, the upper end of the U-shaped groove is open, and the left and right ends respectively have two surfaces extending inward, the two surfaces interact in parallel, and the two interactive surfaces There is a gap between them, the gap is less than or equal to the diameter of the threading thread, and the suture can enter the thread hole through the gap between the open interaction surfaces of the needle tail, but it cannot come out of the needle tail in the same way, which greatly saves the time of threading the needle, and does not require good eyesight and Hand-eye coordination, thus speeding up the operation and reducing the pain of the patient.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings of the embodiments (taking the 1/2 arc suture circular needle commonly used in clinical practice as an example):

Fig. 1 is the front view of the structure diagram of the embodiment of the present invention;

Figure 2 is an enlarged plan view of the pin tail in Figure 1;

Fig. 3 is an enlarged top view of the needle tail in Fig. 1 .

In the figure, 1. Needle body; 2. Needle tail; 3. Suture thread piercing the needle hole; 4. Oval thread hole; 5. Two interactive surfaces; 6. U-shaped groove; side; 9, gap.

Detailed ways

As shown in Fig. 1 and Fig. 2, a non-wearing medical suture needle includes a curved needle body 1, one end of the curved needle body 1 is pointed, and the other end is a needle hole 2 for suture threads.

As shown in Figure 2 and Figure 3, Figure 2 is an enlarged plan view of the needle tail 2; Figure 3 is an enlarged top view of the needle tail 2. The needle hole 3 of the suture thread is formed by two interactive surfaces 5 at the needle tail, and the two mutual surfaces 5 are inside the needle tail 2 . The suture thread passes through the needle hole 3 to form a U-shaped groove 6 at the end of the needle. The upper end of the U-shaped groove 6 is open, and the left and right ends respectively have two surfaces extending inward. The bottom surface of shaped groove 6 forms oval line hole 4. There is a gap 9 between the two interaction surfaces 5, and the gap 9 is smaller than or equal to the threading diameter.

The upper side of the two interaction surfaces 5 forms a downwardly angled wire edge 7 , and the inner side of the two interaction surfaces 5 forms an upwardly curved retaining line edge 8 . There is a gap 9 between the two interaction surfaces 5, and the gap 9 is smaller than or equal to the thread diameter. When threading, the wire slides into the oval wire hole 4 from the gap 9 between the two interaction surfaces 5, and the wire diameter becomes thinner due to the certain tension when the wire slides in, and it is easy to slide through any wire edge 7. Enter in the oval wire hole 4, after the line entered the oval wire hole 4, the lower end and both sides were in the naturally closed ellipse, and the upper end was blocked by the arc retaining line limit 8 again, and the line was not easy to slide out.

The needle arc diameter is 14mm, the needle body length is 22±1mm, the needle tip is 0.3mm, and the needle tail is 1.2mm.
