Description

Technical Field

[0001] This application relates to the field of suture needles, and more particularly to a medical suture needle. Background Technology

[0002] At the end of a surgical procedure, doctors need to suture the wound. However, due to their structure, existing suture needles make it difficult to thread surgical sutures through the needle eye, causing inconvenience and affecting treatment outcomes. The difficulty and time-consuming nature of threading sutures hinders the rapid progress of the surgery. To overcome this problem, some techniques design the needle eye as an open shape with a suture inlet groove. However, the suture inlet groove is a straight-through structure, making it easy for the surgical suture to slip out.

[0003] Currently, Chinese invention patent application with patent number CN200920027059.4 discloses a surgical suture needle, including a needle body and a needle hole. The needle body is provided with a V-shaped guide groove, one end of which is connected to the needle hole, and the other end is a trumpet-shaped opening.

[0004] Regarding the aforementioned technologies, the inventors believe that during the suture-threading process, the needle is relatively smooth, causing the suture to easily slip off the needle. At the same time, the needle tip can easily scrape the patient's flesh during suturing, causing pain to the patient and greatly inconveniencing the doctor's work. Summary of the Invention

[0005] In order to reduce the occurrence of sutures slipping out of the needle opening of the surgical suture needle, and at the same time reduce the occurrence of the needle opening scraping the patient's wound, this application provides a medical suture needle.

[0006] The medical suture needle provided in this application adopts the following technical solution:

[0007] A medical suture needle includes a needle body, the needle body being arc-shaped, a needle tip being provided at one end of the needle body, and an insertion portion being provided at the end of the needle body away from the needle tip;

[0008] The insertion part includes a fixing part, a limiting part, a connecting part, and a sliding part. The fixing part is connected to the end of the needle body away from the needle tip, the limiting part is connected to the end of the needle body away from the needle tip, and the connecting part is fixedly connected to the end of the fixing part away from the needle body.

[0009] The end of the sliding part away from the connecting part is located between the fixing part and the limiting part. The connecting part is arc-shaped. The gap between the sliding part and the limiting part is the sliding entrance. The gap between the limiting part and the fixing part and the gap between the sliding part and the fixing part are the fixing entrances. The sliding entrance faces the center of the needle body.

[0010] By adopting the above technical solution, during the threading process, the suture slides along the needle body and the limiting part, and during the sliding process, it comes into contact with the sliding part and enters the sliding entrance. Then, it enters the fixing entrance along the sliding entrance. Since the sliding entrance is oriented towards the center of the needle body, the suture can slide into the sliding entrance along the arc and is not easy to fall off the needle body. At the same time, during the suturing process, it is mainly the fixing part that comes into contact with the patient's wound, and the limiting part and the sliding part are less likely to scrape the patient's muscle tissue, thus improving the safety of the suturing process.

[0011] Optionally, the limiting portion is positioned away from the needle body and towards the sliding portion.

[0012] By adopting the above technical solution, the end of the restrictor away from the needle body guides the suture, making it easier for the suture to slide into the insertion opening, while also preventing it from scratching the patient's wound.

[0013] Optionally, the thickness of the fixing part is greater than the thickness of the sliding part.

[0014] By adopting the above technical solution, the suture needle is less likely to break during the wound suturing process.

[0015] Optionally, the sliding part is elastic, and when no thread is being threaded, the sliding part abuts against the restricting part.

[0016] By adopting the above technical solution, the sliding part and the restricting part abut against each other, making it difficult for the suture to slip out of the fixing opening.

[0017] Optionally, the end of the sliding portion away from the connecting portion and the end of the limiting portion away from the needle body are smoothly disposed.

[0018] By adopting the above technical solution, the sliding part and the restriction part are less likely to scrape the patient's wound.

[0019] Optionally, the gap between the limiting part and the fixing part is arc-shaped.

[0020] By adopting the above technical solution, it is convenient for the suture to slide into the fixation opening.

[0021] Optionally, the center of the arc is located in the gap between the sliding part and the fixed part.

[0022] By adopting the above technical solution, the suture is less likely to slip out from the gap between the restricting part and the fixing part.

[0023] Optionally, the limiting part is located within the extension line of the arc where the needle body is located, and the end of the sliding part near the connecting part is located within the extension line of the arc where the needle body is located.

[0024] By adopting the above technical solution, the ends of the needle body, the limiting part, and the sliding part near the connecting part are located within the same arc, making it less likely to scratch the wound and improving safety during use.

[0025] Optionally, the limiting part is located within the extension line of the arc where the needle body is located, and the extension line of the arc where the needle body is located is located between the end of the sliding part near the connecting part and the fixing part.

[0026] By adopting the above technical solution, the suture contacts the end of the sliding part near the connecting part during the sliding process, and thus slides into the sliding entrance, which facilitates the threading process.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This invention incorporates a limiting part, a sliding part, and a fixing part. During threading, the suture slides along the needle body and the limiting part, and during this sliding process, it comes into contact with the sliding part and enters the sliding entrance. It then enters the fixing entrance along the sliding part. Since the sliding entrance faces the center of the needle body, the suture can slide into the sliding entrance along the arc, making it less likely to come off the needle body. At the same time, during the suturing process, it is mainly the fixing part that comes into contact with the patient's wound, while the limiting part and the sliding part are less likely to scrape against the patient's muscle tissue, thus improving the safety of the suturing process.

[0029] In this invention, the extension line of the arc of the needle body is set between the end of the sliding part near the connecting part and the fixing part. During the sliding process, the suture thread contacts the end of the sliding part near the connecting part, and thus slides into the sliding entrance, which facilitates the threading process.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 and Figure 2 The present invention provides a first embodiment of a medical suture needle, the medical suture needle including a needle body 1, the needle body 1 being arc-shaped, a needle tip 2 being provided at one end of the needle body 1, and an insertion part 3 being provided at the end of the needle body 1 away from the needle tip 2.

[0035] The insertion part 3 includes a fixing part 31, a limiting part 32, a connecting part 33 and a sliding part 34. The fixing part 31 is connected to the end of the needle body 1 away from the needle tip, the limiting part 32 is connected to the end of the needle body 1 away from the needle tip, and the connecting part 33 is fixedly connected to the end of the fixing part 31 away from the needle body 1.

[0036] The end of the sliding part 34 away from the connecting part 33 is located between the fixing part 31 and the limiting part 32. The connecting part 33 is arc-shaped. The gap between the sliding part 34 and the limiting part 32 is the sliding entrance 35. The gap between the limiting part 32 and the fixing part 31 and the gap between the sliding part 34 and the fixing part 31 are the fixing entrance 36. The sliding entrance 35 faces the center of the needle body 1.

[0037] During the threading process, the suture slides along the needle body 1 and the limiting part 32. During the sliding process, it comes into contact with the sliding part 34 and enters the sliding entrance 35. Then, it enters the fixing entrance 36 along the sliding entrance 34. Since the sliding entrance 35 is oriented towards the center of the needle body 1, the suture can slide into the sliding entrance 35 along the arc and is not easy to fall off the needle body 1. At the same time, during the suturing process, it is mainly the fixing part 31 that comes into contact with the patient's wound. The limiting part 32 and the sliding part 34 are less likely to scrape the patient's muscle tissue, which improves the safety of the suturing process.

[0038] The limiting part 32 is positioned away from the needle body 1 and facing the sliding part 34. The end of the limiting part 32 away from the needle body 1 guides the suture, making it easier for the suture to slide into the sliding entrance 35, while also preventing it from scratching the patient's wound.

[0039] The thickness of the fixing part 31 is greater than the thickness of the sliding part 34. This makes it less likely for the suture needle to break during wound closure.

[0040] The sliding part 34 is elastic, and when no thread is being threaded, the sliding part 34 abuts against the restricting part 32. The abutment between the sliding part 34 and the restricting part 32 makes it difficult for the suture to slip out of the fixing opening 36.

[0041] The end of the sliding part 34 away from the connecting part 33 and the end of the limiting part 32 away from the needle body 1 are smoothly disposed. The sliding part 34 and the limiting part 32 are less likely to scrape the patient's wound.

[0042] The gap between the restricting part 32 and the fixing part 31 is arc-shaped. This facilitates the suture sliding into the fixing opening 36. The center of the arc is located in the gap between the sliding part 34 and the fixing part 31. This prevents the suture from easily slipping out of the gap between the restricting part 32 and the fixing part 31.

[0043] The limiting part 32 is located within the extension line of the arc where the needle body 1 is located, and the end of the sliding part 34 near the connecting part 33 is also located within the extension line of the arc where the needle body 1 is located. The needle body 1, the limiting part 32, and the end of the sliding part 34 near the connecting part 33 are all located within the same arc, which makes it less likely to scratch the wound and improves safety during use.

[0044] Working principle:

[0045] During the threading process, the suture slides along the needle body 1 and the limiting part 32. During the sliding process, it comes into contact with the sliding part 34 and enters the sliding entrance 35. Then, it enters the fixing entrance 36 along the sliding entrance 34. Since the sliding entrance 35 is oriented towards the center of the needle body 1, the suture can slide into the sliding entrance 35 along the arc and is not easy to fall off the needle body 1. At the same time, during the suturing process, it is mainly the fixing part 31 that comes into contact with the patient's wound. The limiting part 32 and the sliding part 34 are less likely to scrape the patient's muscle tissue, which improves the safety of the suturing process.

[0046] Example 2

[0047] The difference between this embodiment and Embodiment 1 is that the limiting part 32 is located within the extension line of the arc where the needle body 1 is located, and the extension line of the arc where the needle body 1 is located between the end of the sliding part 34 near the connecting part 33 and the fixing part 31. During the sliding process, the suture contacts the end of the sliding part 34 near the connecting part 33, thereby sliding smoothly into the sliding entrance 35, which facilitates threading.

[0048] Working principle: During the sliding process, the suture comes into contact with the end of the sliding part 34 near the connecting part 33, and thus slides into the sliding entrance 35, which facilitates the threading process.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
