Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a skin suture device. Background Technology

[0002] In skin suturing, a skin stapler is typically used. Similar to the back of a stapler, the skin stapler secures the sutures to the skin and sutures it. Existing skin staplers include a handle with an anvil plate fixed to it. A suture staple anvil is mounted on the anvil plate. To secure the anvil plate and suture staple anvil together, a fixing post is provided on the anvil plate, and a fixing hole matching the fixing post is opened on the suture staple anvil. One end of the fixing post passes through the fixing hole, and then the end of the fixing post is heat-fused to form a rivet-like structure, completing the fixation. However, the lower end of the anvil plate is snapped into the suture staple anvil. Due to factors such as manufacturing and installation precision, it is easy for the anvil plate and suture staple anvil to not snap properly. Since a channel for the suture staple is formed between the suture staple anvil and the anvil plate, when the skin stapler is in use, the fixing post can easily detach due to improper riveting, and the lower end of the suture staple anvil can also detach, making skin suturing impossible and reducing surgical efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing anvil plate and the suture anvil plate are not properly riveted, resulting in the separation of the fixing post and the lower end of the suture anvil plate, a skin suture device is provided.

[0004] The technical solution adopted by this invention to solve its technical problem is: a skin suture device, including a handle and a staple storage box disposed on the handle. The staple storage box includes an anvil plate and a staple anvil plate. The staple anvil plate has a fixed section and a shaping section connected in sequence. The fixed section and the shaping section are arranged to cross each other along the axial direction of the staple anvil plate. The fixed section is engaged with the anvil plate. The anvil plate is provided with a limiting groove for limiting the displacement range of the staple anvil plate. The shaping section matches the limiting groove, and one end of the shaping section is disposed in the limiting groove. Compared with the prior art, this solution achieves a more stable and reliable positioning of the staple anvil plate and a more stable and reliable engagement of the staple anvil plate by interlocking the fixed section with the anvil plate and cooperating with the limiting groove of the anvil plate. That is, the fixed section and the shaping section are bent at one end angle to each other, forming a mutual constraint.

[0005] In some preferred embodiments, the anvil plate is provided with a locking block, and the sewing nail anvil plate is provided with a locking hole that matches the locking block, and the locking block is locked in the locking hole.

[0006] In some preferred embodiments, the limiting groove is arranged along the axial direction of the card hole.

[0007] In some preferred embodiments, the end of the forming section away from the fixed section abuts against the limiting groove.

[0008] In some preferred embodiments, the fixed section and the forming section have a rounded transition.

[0009] In some preferred embodiments, the anvil plate is provided with a positioning groove that matches the sewing nail anvil plate, and the sewing nail anvil plate is disposed in the positioning groove.

[0010] The beneficial effects of this invention are as follows: When the skin suture device of this invention is in use, the fixed section of the suture anvil and the anvil plate interlock with each other. At the same time, the forming section on the suture anvil, which is intersected with the fixed section, cooperates with the limiting groove of the anvil plate to limit the movement. That is, the fixed section and the forming section are bent at one end angle to each other, forming a mutual constraint. This ensures that the limiting of the suture anvil is stable and reliable, and also ensures that the interlocking of the suture anvil is stable and reliable. During the operation, the forming section will not loosen, avoiding the problem of the existing anvil plate and suture anvil not being riveted properly, which leads to the detachment of the fixed post and the lower end of the suture anvil.

[0022] The present invention will be further described in detail below with reference to the embodiments:

[0023] This invention is not limited to the specific embodiments listed below. Those skilled in the art can implement this invention using various other specific embodiments based on the content disclosed herein. Any modifications or alterations made to the design structure and concept of this invention fall within the protection scope of this invention. It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0024] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and for 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, and therefore should not be construed as a limitation of the invention.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] like Figure 1-9As shown, a skin suture device includes a handle 1, on which a staple storage box 2 is fixedly connected. The staple storage box 2 includes an anvil plate 3 and a staple anvil plate 4. The staple anvil plate 4 has a fixing section 5 and a shaping section 6, which are connected to each other in sequence. In this embodiment, both the fixing section 5 and the shaping section 6 are straight sections, and the fixing section 5 and the shaping section 6 are arranged to cross each other along the axial direction of the staple anvil plate 4. The anvil plate 3 is provided with a limiting groove 7 for limiting the displacement range of the staple anvil plate 4. The shaping section 6 matches the limiting groove 7, and one end of the shaping section 6 is disposed in the limiting groove 7.

[0027] A locking block 8 is provided on the anvil plate 3, and a locking hole 9 matching the locking block 8 is provided on the sewing anvil plate 4. The locking block 8 passes through the locking hole 9 and is locked in the locking hole 9, so that the fixing section 5 and the anvil plate 3 are mutually locked together. The sewing anvil plate 4 is located between the anvil plate 3 and the handle 1.

[0028] To facilitate the installation of the sewing anvil 4 on the anvil plate 3, the limiting groove 7 is set along the axial direction of the locking hole 9.

[0029] To ensure the stable and reliable positioning of the forming section 6 on the anvil plate 4 and the base plate 3, the end of the forming section 6 away from the fixed section 5 is placed against the limiting groove 7. By placing one end of the forming section 6 against the limiting groove 7, the forming section 6 is guaranteed to be positioned along the axial direction of the anvil plate 4, while also ensuring that the fixed section 5 is tightened, thus ensuring a stable and reliable engagement of the fixed section 5.

[0030] Since the fixed section 5 and the forming section 6 are bent at a certain angle to each other, a rounded transition is made between them to reduce stress concentration. This rounded transition eliminates stress concentration between the fixed section 5 and the forming section 6, ensuring a stable and reliable connection.

[0031] To facilitate the installation of the sewing anvil 4 on the anvil base 3, the anvil base 3 is provided with a positioning groove 10 that matches the sewing anvil 4, and the sewing anvil 4 is placed in the positioning groove 10.

[0032] When installing the above-mentioned skin suture device, first align the forming section 6 of the suture anvil 4 with the limiting groove 7 of the anvil plate 3, and at the same time align the suture anvil 4 with the positioning groove 10, and align the locking hole 9 on the fixing section 5 with the locking block 8 of the anvil plate 3. Then insert the forming section 6 into the limiting groove 7 until the suture anvil 4 enters the positioning groove 10, and the locking block 8 passes through and locks onto the locking hole 9, thus completing the installation of the suture anvil 4 on the anvil plate 3. The installation is simple and quick.

[0033] During use, the limiting groove 7 limits the forming section 6, preventing the separation phenomenon that occurs in the prior art. At the same time, the locking of the fixing section 5 is stable and reliable, preventing the separation phenomenon that occurs in the prior art. In addition, the fixing section 5 is provided with intersecting forming sections 6, that is, the fixing section 5 and the forming section 6 are bent at one end angle to each other, forming a mutual constraint between them, ensuring that the sewing nail anvil 4 is fixed stably and reliably when installed on the anvil plate 3.

[0034] The above description, based on the preferred embodiments of the present invention, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification but must be determined according to the claims.
