Description

Technical Field

[0001] The utility model relates to a skin stapler removal device, in particular to a skin stapler removal device provided with a wire cutting blade. Background Art

[0002] At present, skin staples have been widely used in clinical surgical operations to suture the outermost layer of skin. Compared with traditional surgical sutures, skin staples significantly shorten the operation time, reduce the risk of anesthesia for patients, and reduce the burden on surgeons. In addition, skin staples have moderate tension, which ensures blood supply to the skin after surgery, making the skin heal faster and better, and leaving shallower scars. In clinical practice, skin staples are often removed using a dedicated stapler.

[0003] The current problem is that the existing staple removers have a single function and can only be used to remove skin staples. However, in actual clinical operations, medical staff often need to remove some additional sutures while removing skin staples. For example, small incisions at the patient's drainage tube are mostly sutured with traditional sutures, and the sutures of these incisions are usually removed at the same time as the skin staples on the main incision are removed. In this way, after the skin staples are removed with the staple remover, it is still necessary to use traditional sterilized surgical scissors to remove the sutures. This requires medical staff to replace instruments during the operation, and the operation process is relatively cumbersome. Moreover, from a cost perspective, additional surgical scissors are required, which increases the cost of material use (standard cleaning, sterilization, and packaging of a pair of stainless steel surgical scissors requires at least 10-20 yuan in the entire process). Summary of the invention

[0004] The utility model aims to provide a skin stapler remover provided with a thread cutting blade. In addition to the original function of removing skin staples, the stapler can also be used for cutting sutures.

[0005] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0006] A skin stapler with a thread-cutting blade, the stapler comprising an upper stapler arm and a lower stapler arm, the upper stapler arm and the lower stapler arm being assembled together via a hinged shaft pin; the stapler further comprising a blade, the blade being assembled on the lower stapler arm via a guide displacement mechanism; based on the guide displacement mechanism, the blade can be displaced to an extended blade position state, or to a retracted blade position state; the extended blade position state is a position state where the blade edge end is at the working end of the lower stapler arm; the retracted blade position state is a position state where the blade edge end is away from the working end of the lower stapler arm.

[0007] Furthermore, the guide displacement mechanism is specifically implemented in the form of a structure in which a guide rail hole is provided in the middle of the blade, a guide shaft pin is provided on the lower nail removal arm, and the guide rail hole of the blade is sleeved and assembled on the hinge shaft pin and the guide shaft pin; based on the hinge shaft pin and the guide shaft pin, the blade can be displaced in the direction of the line connecting the hinge shaft pin and the guide shaft pin, thereby forming the guide displacement mechanism.

[0008] Furthermore, when the blade is displaced to a state where the end of the guide rail hole away from the blade end is in close contact with the guide shaft pin, the blade is in a blade-out position; when the blade is displaced to a state where the end of the guide rail hole adjacent to the blade end is in close contact with the hinge shaft pin, the blade is in a blade-retracting position.

[0009] Furthermore, the guide displacement mechanism is specifically implemented in the form of a structure in which a slide groove is provided on the lower nail removal arm, a slider is provided on the blade, and the slider of the blade is assembled with the slide groove of the lower nail removal arm to form the guide displacement mechanism.

[0010] Compared with the prior art, the nail remover of the utility model has the following beneficial effects:

[0011] The stapler of the utility model can not only remove skin staples, but also be used to cut sutures, and has two functions in one. When skin staples and sutures need to be removed at the same time, the stapler of the utility model is used to perform the operation, which not only makes the operation process more convenient, but also reduces the material use cost.

[0015] The utility model is further described below with specific embodiments:

[0016] See also Figures 1 to 5, this embodiment provides a skin staple remover provided with a wire cutting blade.

[0017] See also Figure 1 and Figure 2 The staple remover of this embodiment includes an upper staple remover arm 1 and a lower staple remover arm 2, which are hingedly assembled together through an axle pin, thereby forming a basic configuration of a staple remover, and its basic function is to remove skin staples.

[0018] For the convenience of description, in this article, the ends of the upper staple removal arm 1 and the lower staple removal arm 2 that directly contact the skin staples are referred to as working ends (eg, Figure 1 or Figure 2 The end of the upper nail removal arm 1 and the lower nail removal arm 2 that are held by hand are called the holding end (as shown in FIG. Figure 1 or Figure 2 the right end of the orientation shown in ).

[0019] For the convenience of description, the axle pin for hinged assembly between the upper nail removal arm 1 and the lower nail removal arm 2 is referred to as a hinge axle pin 4 .

[0020] The innovation of the staple remover is that a blade 3 is also provided on the staple remover, so that the staple remover of this embodiment can be used not only to remove skin staples but also to cut sutures.

[0021] Specifically, see Figure 3 The blade 3 is in the shape of a long strip as a whole, and a blade is provided at one end of the long strip. The end provided with the blade is called the blade end of the blade 3.

[0022] See also Figure 4 and Figure 5 The blade 3 is assembled at a position near the working end of the lower nail removal arm 2, and the cutting edge of the blade 3 faces the working end of the lower nail removal arm 2.

[0023] The blade 3 is assembled on the lower nail removal arm 2 through a guide displacement mechanism. Based on the guide displacement mechanism, the blade 3 can perform a one-dimensional displacement action on the lower nail removal arm 2.

[0024] Specifically, the blade 3 can be displaced to a position where the blade end of the blade 3 is at the working end of the lower nail removal arm 2 (eg Figure 4 and Figure 2 For the convenience of description, this position state is referred to as the "blade-out position state".

[0025] On the contrary, the blade 3 can be displaced to a position where the blade end of the blade 3 leaves the working end of the lower nail removal arm 2 (such as Figure 5 and Figure 1For the convenience of description, this position state is referred to as the "retracted blade position state".

[0026] See also Figures 3 to 5 The guiding displacement mechanism is specifically implemented in the following structural form:

[0027] A guide rail hole 31 is provided in the middle of the blade 3, and the guide rail hole 31 is essentially a long strip through hole opened in the middle of the blade 3; in addition to the original hinge axis pin 4, the lower nail removal arm 2 is also provided with a guide axis pin 5; the guide rail hole 31 of the blade 3 is simultaneously sleeved and assembled on the hinge axis pin 4 and the guide axis pin 5, or in other words, the hinge axis pin 4 and the guide axis pin 5 are both penetrated in the guide rail hole 31 of the blade 3, and the blade 3 can only be displaced in the direction of the line connecting the hinge axis pin 4 and the guide axis pin 5, thereby realizing the function of displacement guidance, that is, constituting the guide displacement mechanism.

[0028] See also Figure 4 and Figure 2 When the blade 3 is displaced to the state where "the end of the guide rail hole 31 away from the blade end is close to the guide shaft pin 5", the blade 3 is in the position state of "the blade end of the blade 3 is at the working end of the lower nail removal arm 2", that is, as mentioned earlier, the blade 3 can be displaced to the position state of "the blade end of the blade 3 is at the working end of the lower nail removal arm 2".

[0029] See also Figure 5 and Figure 1 When the blade 3 is displaced to the state where "the end of the guide rail hole 31 adjacent to the blade end is close to the hinge pin 4", the blade 3 is in the position state where "the blade end of the blade 3 leaves the working end of the lower nail removal arm 2", that is, as mentioned earlier, the blade 3 can be displaced to the position state where "the blade end of the blade 3 leaves the working end of the lower nail removal arm 2".

[0030] It should be noted that in other embodiments, other forms of guide displacement mechanisms may be used to achieve the guide displacement function, such as providing a slide groove on the lower nail removal arm 2, providing a slider on the blade 3, and assembling the slider of the blade 3 with the slide groove of the lower nail removal arm 2, which can also achieve the guide displacement function. In the nail remover of the utility model, there is no particular limitation on the specific implementation form of the guide displacement mechanism.

[0031] The staple remover of this embodiment has the basic function of removing skin staples. After the removal of the skin staples is completed, if there are additional sutures that need to be removed, the blade 3 can be moved to the blade-out position. At this time, the staple remover can be used as a pair of scissors to cut the sutures. After the removal of the sutures is completed, the blade 3 is moved to the blade-out position and then discarded into a dedicated medical waste bin for subsequent disinfection.

[0032] In addition to the original function of removing skin staples, the staple remover of this embodiment can also be used to cut sutures, which has two functions in one. When both skin staples and sutures need to be removed in a certain surgical scenario, the staple remover of this embodiment is used to perform the operation, which not only makes the operation process of the surgical operator more convenient, but also reduces the material usage cost.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
