Description

Technical Field

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

[0002] A needle holder is a commonly used instrument in medical and surgical procedures, primarily used to hold suture needles for suturing. Its design considers ergonomics and ease of operation, featuring a needle-holding section at the head, with the gripping force and direction controlled by a handle. Needle holders are typically made of stainless steel, offering excellent corrosion resistance and durability. Various models and designs of needle holders are available depending on the surgical site and requirements. Common needle holders include long needle holders, short needle holders, micro-needle holders, etc. When using a needle holder, the doctor selects the appropriate model to accurately hold the suture needle for suturing. The design of needle holders may vary depending on the department, but their basic function remains the same: to hold the needle. Different models of needle holders have varying degrees of internal texture; the finer the needle, the denser the texture; some models even have no texture, being very smooth.

[0003] Although needle holders come in various styles, they all have one thing in common: a locking mechanism that locks the needle in place. While the locking mechanisms have different designs, they all suffer from being difficult to open and close, meaning the process is laborious and inflexible.

[0004] Furthermore, current needle holders have two horizontal rings. Users typically place their thumb and index finger into one ring to control the opening and closing of the holder. However, everyone's hand size is different, making operation less flexible. Additionally, the overall stability is low when the thumb and other fingers are each in a separate ring, and it's inconvenient to apply force while holding the needle. These issues are particularly pronounced for novice doctors. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0026] In the accompanying drawings, the same reference numerals represent the same parts. It should be noted that the described embodiments are only some, not all, of the embodiments disclosed herein.

[0027] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0028] This utility model needle holder, such as Figures 1 to 3As shown, the device includes a first handle 1, one end of which has a first clamping part 2, the other end of which has a first finger ring 3, and a first connecting part 4 in the middle. It also includes a second handle 6, one end of which has a second clamping part 7, the other end of which has a second finger ring 8, and a second connecting part 9 in the middle. The second connecting part 9 and the first connecting part 4 are movably connected. The first handle 1, second clamping part 2, first finger ring 3, first connecting part 4, second handle 6, second clamping part 7, second finger ring 8, and second connecting part 9 are all existing products, so details will not be elaborated further. The key point is that the first handle 1 has a fixedly connected first sliding sleeve 5. Figure 1 , Figure 2 and Figure 3 The specific structure of the first sliding sleeve 5 is shown; it also includes the first arc-shaped rack 10. Figures 1 to 3 The structure of the first arc-shaped rack was shown from different angles, such as Figure 3 As shown, one end of the first arc-shaped rack 10 is fixedly connected to the first handle 1; the other end of the first arc-shaped rack 10 at least partially passes through the first sliding sleeve 5; further comprising a second arc-shaped rack 11, as shown... Figure 3 As shown, the second arc-shaped rack 11 is movably connected to the first sliding sleeve 5 and / or the first handle 1. Specifically, as... Figure 3 As shown, the first sliding sleeve 5 has a fixedly connected connecting shaft 16; the second arc-shaped rack 11 is movably connected to the connecting shaft 16, that is, the second arc-shaped rack 11 is movably connected to the first sliding sleeve 5 through the connecting shaft 16. Furthermore, as... Figure 2 As shown, the positions of the first arc-shaped rack 10 and the second arc-shaped rack 11 are respectively centered on the first connecting part 4 and / or the second connecting part 9. In this needle holder, when the first handle 1 and the second handle 6 open and close, the second handle 6 drives the second arc-shaped rack 11 to slide back and forth within the first sliding sleeve 5. Since it also includes the second arc-shaped rack 11, when the second arc-shaped rack 11 moves away from the first arc-shaped rack 10, the first arc-shaped rack 10 can slide within the first sliding sleeve 5; however, when the second arc-shaped rack 11 is engaged with the first arc-shaped rack 10, the first arc-shaped rack 10 cannot slide. This utility model needle holder provides a guide rail for the first arc-shaped rack 10 of the second handle 6 by using a first sliding sleeve 5 on the first handle 1; and by using a second arc-shaped rack 11, the first arc-shaped rack 10 can be locked by simply adjusting the position of the second arc-shaped rack 11 and adjusting the engagement or disengagement between the second arc-shaped rack 11 and the first arc-shaped rack 10.

[0030] like Figures 1 to 3 As shown, the needle holder of this utility model also includes a second sliding sleeve 12. Figure 1 , Figure 2 and Figure 3 The renderings of the second sliding sleeve 12 are shown respectively, such as Figure 3 As shown, the second sliding sleeve 12 is slidably mounted on the second handle 6; the second finger ring 8 is fixedly connected to the second sliding sleeve 12. Fasteners 13 are also included. Figures 1 to 3 The fastener 13 is shown to be threadedly connected to the second sliding sleeve 12. Specifically, a threaded hole is provided on the side of the second sliding sleeve 12, and the fastener 12 is threadedly connected to the second sliding sleeve 12 through the screw hole. Furthermore, the end of the fastener 13 is at least partially located within the second sliding sleeve 12. This utility model's needle holder, by adding a second sliding sleeve 12 and installing a second finger ring 8 on it, allows the position of the second finger ring 8 to be adjusted above the second handle 6. This allows the user to adjust the position of the second finger ring 8 towards the second connecting part 9, adapting to different hand sizes and making the operator's hand operation more flexible. Additionally, the operator can place their thumb inside the second finger ring 8 and their middle or ring finger inside the first finger ring 3, with the index and / or middle fingers assisting in gripping the first handle 1. The needle holder is positioned at the web of the hand, thus increasing the stability of the needle holder and making it easier for the operator to apply force.

[0031] like Figure 3 As shown, in this needle holder, the second sliding sleeve 12 has a slider 14 fixedly connected inside; the second handle 6 has a groove 15, and the slider 14 is at least partially slidably installed in the groove 15. The slider 14 and the groove 15 make the sliding between the second sliding sleeve 12 and the second handle 6 more stable.
