Abstract
The utility model discloses an improved sewing needle and line, which comprises a sewing needle and a sewing line, wherein the tail part of the sewing needle is provided with a needle hole, and the improved sewing needle and line is characterized in that the sewing line comprises a main body using section and a needle line connecting section, the outer diameter of the needle line connecting section is smaller than that of the main body using section, the needle line connecting section is connected with the main body using section through a transition section which is gradually thickened, the outer diameter of the needle line connecting section is matched with the inner diameter of the needle hole, the needle line connecting section is fixedly connected with the needle hole at the tail part of the sewing needle, and the maximum outer diameter ratio of the sewing needle to the sewing line is close to 1: 1.
Description
Technical Field
The utility model relates to a surgical instrument, in particular to an improved structure of a suture needle and a suture thread.
Background
According to the common suture needle and the suture thread, the needle needs to be connected with the thread, the needle diameter needs to be larger than the thread diameter, sometimes the needle diameter is large, the thread cannot block a needle eye, blood seepage from the needle eye is common, the visual field is influenced, the operation difficulty is increased, chronic blood loss of a patient is caused, the infection chance of the patient is increased, and if the needle diameter is close to the thread diameter as much as possible, the needle eye can be blocked by the thread, and the blood seepage from the needle eye is reduced or prevented.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a structural design that the outer diameters of a suture needle and a suture line are as close as possible.
The technical scheme for realizing the aim is as follows: an improved suture needle and thread, comprising a suture needle and a suture thread, wherein the tail part of the suture needle is provided with a needle hole, the suture thread comprises a main body using section and a needle thread connecting section, the outer diameter of the needle thread connecting section is smaller than that of the main body using section, the needle thread connecting section is connected with the main body using section through a transition section which is gradually thickened, the outer diameter of the needle thread connecting section is matched with the inner diameter of the needle hole, the needle thread connecting section is fixedly connected with the needle hole at the tail part of the suture needle, and the maximum outer diameter ratio of the suture needle to the suture thread is close to 1: 1.
preferably, the suture needle is a round needle or a round angle needle.
Preferably, the total length of the needlework connecting section and the transition section is less than 2 cm.
The suture needle line has the advantages that the needle line connecting section is thin, so that a thin needle hole can be inserted, and a thin suture needle can be selected, so that the outer diameters of the main body using section and the suture needle are close to each other as much as possible, and the purpose of blocking a needle hole and preventing the needle hole from bleeding is achieved.
The use of a round needle is preferred because the eye of the round needle is the smallest.
Round angle needles are preferred because of the sharp tip and lower penetration force.
The suture needle and the suture thread of the utility model have simple design and easy production by the existing processing means, and can solve the common needle eye bleeding problem in the clinical surgery, in particular to the micro-wound operation.
Drawings
FIG. 1 is a schematic view of the structure of the suture of the present invention.
FIG. 2 is a schematic view of a needle hole at the end of a suture needle.
In the figure: 1. the needle comprises a suture needle, 2 a suture line, 3 a needle hole, 4 a needle line connecting section, 5 a main body using section and 6 a transition section.
Detailed Description
The following detailed description is to be read with reference to the drawings and the accompanying detailed description.
Referring to fig. 1 and 2, the suture needle and thread of the present invention comprises a suture needle 1 and a suture thread 2, wherein the tail part of the suture needle 1 is provided with a needle hole 3, the suture thread 2 comprises a needle and thread connecting section 4 and a main body using section 5, the outer diameter of the needle and thread connecting section 4 is smaller than the outer diameter of the main body using section 5, the outer diameter of the needle and thread connecting section 4 is matched with the inner diameter of the needle hole 3, and the needle and thread connecting section 4 and the needle hole 3 at the tail part of the suture needle are pressed into a whole.
Between the needle thread connecting section 4 and the main body using section 5 is a transition section 6 which is gradually increased from thin to thick. The ratio of the outer diameter of the main body using section 5 to the maximum outer diameter of the suture needle 1 is close to 1: 1, thereby the stylolite can be fine the pinhole shutoff suture needle, plays the effect of preventing the pinhole seepage blood, produces cleaner operation surface of a wound.
The sewing needle 1 is a round needle or a round angle needle.
The total length of the needle thread connecting section 4 and the transition section 6 is less than 2 cm.
In surgical practice, the suture is hardly used for the needle and thread connecting section 4 and the transition section 6, the needle and thread connecting section 4 and the transition section 6 have only connecting function and no sewing function actually, and only the main body using section 5 has the sewing function, so that the needle and thread connecting section 4 has a thinner caliber and does not influence the use strength of the suture.
Claims (3)
1. An improved suture needle and thread, comprising a suture needle and a suture thread, wherein the tail part of the suture needle is provided with a needle hole, the suture thread comprises a main body using section and a needle thread connecting section, the outer diameter of the needle thread connecting section is smaller than that of the main body using section, the needle thread connecting section is connected with the main body using section through a transition section which is gradually thickened, the outer diameter of the needle thread connecting section is matched with the inner diameter of the needle hole, the needle thread connecting section is fixedly connected with the needle hole of the tail part of the suture needle, and the maximum outer diameter ratio of the suture needle to the suture thread is close to 1: 1.
2. the improved needle thread of claim 1 wherein said needle is a round or round angle needle.
3. The improved needle thread of claim 1 wherein the combined length of said needle thread connecting and transition sections is less than 2 cm.
