Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a surgical suture needle threading device. Background Technology

[0002] Needle threading is a crucial step in surgical procedures, and its efficiency and precision directly impact the surgical outcome. With the rapid development of minimally invasive techniques, the need for needle threading by operating room nurses has decreased. However, in complex open surgeries and emergency intraoperative suturing, automated needle threading devices can shorten threading time and ensure accuracy, improving surgical efficiency. These devices also integrate sharps storage and management functions, minimizing direct contact between nurses and suture needles, fundamentally reducing the probability of sharps injuries and providing strong protection for the occupational safety of medical personnel.

[0003] A medical suture threader, disclosed in CN211796668U, includes a base with multiple needle grooves compatible with different suture needle models. The tails of the needle grooves overlap. A threading groove extends laterally through the tail of each needle groove and protrudes outward from the side of the base. A suture guide ring is slidably installed within the threading groove, allowing the suture needle to pass through its threading hole when installed in the needle groove. A left-right extending screw is rotatably mounted on the base, automatically threading the suture needle via the suture guide ring. This method is fast, requires minimal visual acuity from the user, and allows for continuous threading, preventing delays in surgical progress. While existing medical suture threaders can accelerate threading, they typically only allow threading one suture needle at a time. In complex surgeries with large wounds or complex anatomical areas requiring multiple repairs, and where different tissues require different suturing methods, dozens of suture needles are often used, resulting in low threading efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that in some complex surgeries, up to dozens of suture needles are often used, and the needle threading efficiency is low. It provides a surgical suture needle threading device that can push the threading holes of multiple suture needles on the placement component to the threading component for threading, thereby speeding up the threading efficiency. At the same time, it can be replaced by sliding a slide to another placement component with a fixed suture needle, thereby improving the threading efficiency in more complex surgeries.

[0005] To achieve the above objectives, this utility model provides a surgical suture needle threading device, including a base, an installation component and a pushing component connected above the base, a plurality of threading components connected to one side of the installation component, and a placement component detachably connected to one side of the pushing component, wherein a plurality of suture needles are disposed on the placement component; the placement component includes a sliding plate, which is slidably connected to the pushing component, and a plurality of fixing blocks are disposed on the sliding plate, each fixing block having a needle groove for fixing the suture needle.

[0006] As a further description of the above technical solution: the installation assembly includes an electric lifting rod, the lower part of which is connected to a base, and an installation plate is connected to the upper part of the electric lifting rod, the installation plate being connected to multiple wiring assemblies.

[0007] As a further description of the above technical solution: the pushing component includes an electric retractable rod, the lower part of which is connected to the base, and one end of the electric retractable rod is connected to a push plate, the push plate having a groove adapted to the sliding plate.

[0008] As a further description of the above technical solution: the threading assembly includes a connecting rod, one end of which is connected to the mounting assembly, and the other end of which is connected to a threading ring, which can pass through the threading hole of the suture needle.

[0009] As a further description of the above technical solution: the threading loop is in the shape of a rhombus, with one vertex of the long diagonal of the rhombus pointing toward the threading hole of the suture needle.

[0010] As a further description of the above technical solution: the connecting rod is detachably connected to the mounting plate by bolts.

[0011] As a further description of the above technical solution: a limiting groove is provided on the base.

[0012] As a further description of the above technical solution: the bottom of the base is provided with an anti-slip pad, and a control panel is provided on one side of the base.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] This invention controls the operation of the push component, which can push the threading holes of multiple suture needles on the placement component towards the threading component for threading, thus speeding up the threading efficiency. At the same time, multiple suture needles can be pre-clamped and fixed on multiple placement components. After the suture needle on one placement component is threaded, it can be slid on a slide to replace it with another placement component with a fixed suture needle, thus improving the threading efficiency in more complex surgeries.

[0021] 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.

[0022] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-4 As shown, the surgical suture needle threading device of this utility model includes a base 1, an installation component 2 and a pushing component 3 connected above the base 1, a plurality of threading components 4 connected to one side of the installation component 2, and a placement component 5 detachably connected to one side of the pushing component 3. A plurality of suture needles 6 are provided on the placement component 5. The placement component 5 includes a slide plate 51, which is slidably connected to the pushing component 3. A plurality of fixing blocks 52 are provided on the slide plate 51, and each fixing block 52 is provided with a needle groove 53 for fixing the suture needle 6.

[0025] In the technical solution of this utility model, multiple suture needles 6 to be threaded are snapped into the needle grooves 53 of the fixing block 52, and then the multiple fixing blocks 52 and their fixed suture needles 6 are slidably connected to the pushing component 3 by the sliding plate 51. By controlling the operation of the pushing component 3, the threading holes of multiple suture needles 6 on the placement component 5 can be pushed towards the threading component 4 for threading, which speeds up the threading efficiency. At the same time, multiple suture needles 6 can be snapped and fixed on multiple placement components 5 in advance. After the suture needle 6 on one placement component 5 is threaded, it can be slidably replaced by another placement component 5 with a fixed suture needle 6 by the sliding plate 51, which improves the threading efficiency in more complex surgeries.

[0026] like Figure 1 As shown, specifically, the mounting component 2 includes an electric lifting rod 201, which is connected to the base 1 at the bottom and a mounting plate 202 is connected to the top of the electric lifting rod 201. The mounting plate 202 is connected to multiple threading components 4. By controlling the operation of the electric lifting rod 201, the mounting plate 202 can be raised and lowered, and the height of the threading components 4 can be adjusted to accommodate different sizes of suture needles 6.

[0027] like Figure 1 and Figure 4 As shown, specifically, the pushing component 3 includes an electric retractable rod 31, which is connected to the base 1 at the bottom. One end of the electric retractable rod 31 is connected to a pushing plate 32, and the pushing plate 32 has a groove 33 that is adapted to the sliding plate 51. By controlling the operation of the electric retractable rod 31, the pushing plate 32 can be moved, which in turn moves the placement component 5 and the suture needle 6 fixed above it, so that the threading hole on the suture needle 6 passes through the threading ring 42, which facilitates threading the suture through the threading ring 42.

[0028] like Figure 1 and Figure 3As shown, specifically, the suture assembly 4 includes a connecting rod 41, one end of which is connected to the mounting assembly 2, and the other end of which is connected to a suture ring 42. The suture ring 42 can pass through the suture hole of the suture needle 6. The suture ring 42 automatically sutures the suture needle 6, and the suture is sutured quickly, requiring less visual acuity from the user. It can suture continuously, speeding up the suture process and preventing delays in the surgical procedure.

[0029] Specifically, the thread loop 42 is a rhomboid ring, with one apex of the long diagonal of the rhomboid ring facing the thread hole of the suture needle 6. The thread loop 42 can be made of shape memory metal such as nickel-titanium alloy. Since one apex of the long diagonal of the rhomboid ring 42 faces the thread hole of the suture needle 6, the thread loop 42 can pass through the thread hole of the suture needle 6. With the above structure, the thread loop 42 can be made in a larger size, deforms when passing through the thread hole of the suture needle 6, and returns to a rhomboid shape after passing through the thread hole of the suture needle 6, making it convenient for the user to pass the suture thread through the thread loop 42. Furthermore, the rhomboid shape of the thread loop 42 makes it easier for the user to pass the suture thread through the thread hole of the suture needle 6.

[0030] like Figure 1 and Figure 3 As shown, specifically, the connecting rod 41 is detachably connected to the mounting plate 202 by bolts 7; the bolts 7 facilitate the installation and removal of the connecting rod 41, and make it easy to remove and install the threading ring 42 on the connecting rod 41, and to disinfect and replace the threading ring 42.

[0031] like Figure 1 As shown, specifically, a limiting groove 8 is provided on the base 1, an anti-slip pad 9 is provided at the bottom of the base 1, and a control panel 10 is provided on one side of the base 1; the limiting groove 8 can limit the push plate 32, which enhances the stability of the push plate 32 when it moves, and the control panel 10 can control the operation of the threading device.

[0032] Working principle: By engaging multiple suture needles 6 to be threaded in the needle grooves 53 of the fixing block 52, and then sliding the multiple fixing blocks 52 and their fixed suture needles 6 onto the pushing component 3 via the sliding plate 51, the pushing component 3 can be controlled to push the threading holes of multiple suture needles 6 on the placement component 5 toward the threading component 4 for threading, thus speeding up the threading efficiency. At the same time, multiple suture needles 6 can be pre-engaged and fixed on multiple placement components 5. After the suture needles 6 on one placement component 5 are threaded, they can be slidably replaced by another placement component 5 with fixed suture needles 6 via the sliding plate 51, thus improving the threading efficiency in more complex surgeries.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
