Description

Technical Field

[0001] The utility model relates to the technical field of skin staplers, and more particularly to a non-invasive skin stapler that is quick and easy to use. Background Art

[0002] Non-invasive skin staplers can reduce patient pain, improve surgical efficiency, improve blood circulation, accelerate wound healing, and facilitate dressing changes and disinfection, thereby reducing the chance of infection. However, existing non-invasive skin staplers require repeated operation of multiple sets of separate staplers one by one when performing anastomosis on a wound, thereby increasing the operation complexity and anastomosis time of the stapler, and are prone to errors, resulting in irregular wound anastomosis.

[0003] In this regard, Chinese Patent Publication No. CN218899557U discloses "a non-invasive skin stapler that is easy to use quickly, comprising a connecting stapler assembly, wherein the stapler assembly is provided in two groups, and the middle portions of the two groups of stapler assemblies are slidably connected by fixed guide bars, the outer end surfaces of the fixed guide bars are symmetrically provided with connecting guide bars, and the inner end surfaces of the two groups of stapler assemblies are threadedly connected near the upper portions by stapler limiter assemblies that are evenly and equidistantly distributed."

[0004] The above patent synchronously holds two sets of adjacent connecting knobs, so that the two sets of bidirectional screw rods drive the two sets of anastomosis adhesive plates to move centripetally, and then the anastomosis adhesive plates can be used to pull the skin. This method can only operate two sets of anastomosis adhesive plates at a time. Since multiple sets of anastomosis adhesive plates are required for anastomosis during the skin anastomosis operation, the operation method of this patent is still inconvenient. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a non-invasive skin stapler that is quick and easy to use and has the advantage of enabling multiple groups of anastomotic adhesive seats to move simultaneously to perform skin anastomosis by rotating a worm, thereby increasing the anastomosis speed.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a non-invasive skin stapler that is easy to use quickly, comprising a plurality of parallel guide rods, both ends of which are fixedly connected with blocks, a plurality of guide rods are slidably connected with anastomotic adhesive seats symmetrically distributed along the midline of the guide rods, a mounting frame is provided between the anastomotic adhesive seats at the same end, a positioning member for positioning and fixing the mounting frame is provided at the top end of the plurality of anastomotic adhesive seats, and a driving component for driving the two mounting frames to move toward or away from each other is provided between the two mounting frames.

[0007] As a preferred technical solution of the present invention, the vertical cross-section of the mounting frame is an L-shaped structure, and the vertical cross-section of the anastomotic adhesive seat is a U-shaped structure.

[0008] As an optimal technical solution of the present invention, the driving assembly includes several bidirectional screws corresponding one to one with the guide rods, the two ends of the bidirectional screws are respectively threadedly connected to two mounting brackets, the ends of the two bidirectional screws are fixedly connected to the limiting blocks, the middle parts of the several bidirectional screws are fixedly connected to the worm gears, and the two mounting brackets are provided with manual parts for driving the several worm gears to rotate simultaneously.

[0009] As a preferred technical solution of the present invention, the manual part includes two sleeves, both ends of the two sleeves are slidably connected with a sleeve rod, the end of the sleeve rod away from the corresponding sleeve is fixedly connected to the corresponding mounting frame, the bottoms of the two sleeves are fixedly connected with a mounting plate, a worm is rotatably connected between the two mounting plates, several worm wheels are engaged with the worm, and one end of the worm is fixedly connected to a handwheel.

[0010] As an optimal technical solution of the present invention, the positioning member includes a sliding rod, which passes through the top wall of the anastomotic bonding seat and is slidably connected to the anastomotic bonding seat. The bottom end of the sliding rod is fixedly connected to a wedge-shaped limit block, and the top end of the sliding rod is fixedly connected to a pull block. The bottom end of the mounting frame is provided with a plurality of slots that slideably cooperate with the wedge-shaped limit block.

[0011] As an optimal technical solution of the present invention, the top wall on the inner side of the anastomotic bonding seat is provided with a receiving groove that slides with the wedge-shaped limit block, and a spring is sleeved on the sliding rod. The top end of the spring contacts the inner wall of the receiving groove, and the bottom end of the spring contacts the wedge-shaped limit block.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: by rotating the handwheel to rotate the worm, all the worm wheels rotate synchronously, which also causes all the bidirectional screws to rotate synchronously, so that the two mounting frames can move toward each other, thereby causing the two anastomotic adhesive seats on the same bidirectional screw to slide toward each other, which also causes multiple groups of anastomotic adhesive seats to move toward each other at the same time and pull the skin, quickly and stably closing the wound, and greatly improving the anastomosis speed of the wound.

[0019] like Figures 1 to 4 As shown, the utility model provides a non-invasive skin stapler that is easy to use quickly, including a number of parallel guide rods 2, both ends of which are fixedly connected with blocks 3, and a number of guide rods 2 are slidably connected with anastomotic adhesive seats 1 symmetrically distributed along the midline of the guide rods 2, a mounting frame 4 is provided between the anastomotic adhesive seats 1 at the same end, the vertical cross-section of the mounting frame 4 is an L-shaped structure, and the vertical cross-section of the anastomotic adhesive seat 1 is a U-shaped structure, the top ends of the several anastomotic adhesive seats 1 are provided with positioning members 5 for positioning and fixing the mounting frame 4, and a driving component 6 for driving the two mounting frames 4 to move toward or away from each other is provided between the two mounting frames 4.

[0020] Among them, the driving assembly 6 includes several bidirectional screws 61 corresponding to the guide rods 2 one by one, and the two ends of the bidirectional screws 61 are respectively threadedly connected to the two mounting brackets 4, the ends of the two bidirectional screws 61 are fixedly connected to the limiting blocks 62, and the middle parts of the bidirectional screws 61 are fixedly connected to the worm gears 63. The two mounting brackets 4 are provided with manual parts 64 for driving the worm gears 63 to rotate simultaneously. The manual parts 64 include two sleeves 641, and the two ends of the two sleeves 641 are slidably connected to the sleeve rods 642. The ends of the sleeve rods 642 away from the corresponding sleeves 641 are fixedly connected to the corresponding mounting bracket 4. The bottoms of the two sleeves 641 are fixedly connected to the mounting plates 643, and the worm 644 is rotatably connected between the two mounting plates 643. The several worm gears 63 are meshed with the worm 644, and one end of the worm 644 is fixedly connected to the handwheel 645.

[0021] By turning the hand wheel 645 to rotate the worm 644, all the worm wheels 63 are rotated synchronously, and all the bidirectional screws 61 are rotated synchronously, so that the two mounting frames 4 can move toward each other, thereby making the two anastomotic adhesive seats 1 on the same bidirectional screw 61 slide toward each other, and multiple groups of anastomotic adhesive seats 1 move toward each other at the same time and pull the skin, closing the wound quickly and stably, greatly improving the anastomosis speed of the wound.
