Description

Technical Field

[0001] The invention belongs to the technical field of suturing tools, in particular to a multifunctional skin stapler used for animal experiments. Background Art

[0002] Although skin staplers have been widely used in surgical operations, traditional sutures are still used to close skin incisions in animal experiments. The many disadvantages of sutures in animal experiments are a headache for experimenters. Similar to human surgery, the use of sutures to close skin incisions in animal experiments also has disadvantages such as being time-consuming and prone to infection. The differences between experimental animals and humans in terms of body shape, skin texture, and anti-infection ability may further amplify the disadvantages of sutures.

[0003] Based on the many advantages of skin staplers in human surgery, their application in animal experiments is expected to significantly shorten skin suturing time, reduce wound infection rates, and promote wound healing. At the same time, skin staplers are hard and firmly fixed, and are not easily damaged by experimental animals. In addition, skin staplers can avoid needle punctures and reduce the pain of removal, which is beneficial to protecting the safety of experimenters and improving the welfare of experimental animals. Unfortunately, the application value of skin staplers in the field of animal experiments lacks attention, and skin staplers for animal experiments have not yet been developed, so there is a gap in this field that needs to be filled urgently.

[0004] After searching, in the skin stapler with replaceable stapler magazine with announcement number CN117982186A, the application provides a skin stapler with replaceable stapler magazine, which relates to the field of medical device technology. The skin stapler with replaceable stapler magazine includes a firing assembly and a stapler magazine, the firing assembly includes a bracket, the stapler magazine and the bracket are slidably connected, and a lock buckle is rotatably provided on the bracket, which can be engaged with the stapler magazine, which can improve the utilization rate of the skin stapler and reduce product consumption, but the device still has some problems in actual operation:

[0005] 1. When the above-mentioned skin stapler is in use, there is no limit assembly between the two handles, which may easily cause the device to be accidentally touched during use, which may cause the risk of accidental injury;

[0006] 2. When the above-mentioned skin stapler is in use, when the staple cartridge needs to be replaced, the connecting column needs to be twisted to separate it from the hook before the staple cartridge can be pulled out. The operation process is not only cumbersome, but also after the connecting column is separated from the hook, the staple cartridge cannot pop out by itself, and the user needs to pull it out to remove the staple cartridge, which is more troublesome.

[0007] Therefore, in view of the above problems, a multifunctional skin stapler for animal experiments is proposed. Summary of the invention

[0045] Through the above scheme: by providing a nail pushing plate 46 connected by two fourth springs 45 in the magazine box 41, after the magazine box 41 is loaded with nails, the nails can be pushed by the nail pushing plate 46 and always kept on the right side of the magazine box 41, thereby preventing the situation where the nails are not used up but the gun is empty when the device is used.

[0046] Further Figure 8 and Fig. 9As shown, the connecting member 43 includes a third fixing plate 431 and a second fixing rod 432, a circular through hole 433 is opened in the middle of the right side of the third fixing plate 431, a soft rubber ring 434 is fixedly connected to the inner surface of the circular through hole 433, a cone ring 435 and a second limiting ring 436 are fixedly connected to the left side of the second fixing rod 432 and a double-headed cone block 437 is slidably connected, the third fixing plate 431 is fixedly connected to the middle side of the inside of the second mounting groove 16, the second fixing rod 432 is fixedly connected to the extension block 42, the cone ring 435 is located on the left side of the second limiting ring 436, and the double-headed cone block 437 is located between the cone ring 435 and the second limiting ring 436, and both the cone ring 435 and the double-headed cone block 437 can pass through the soft rubber ring 434.

[0047] Through the above solution: by providing a connecting member 43 between the lower component 1 and the magazine box 41, when the device is replacing nails, the magazine box 41 can be easily taken out and installed, making the device more convenient to use.

[0048] Working principle: When using the device, the upper component 2 and the lower component 1 of the handheld device are pressed, and the lower pressing plate 24 in the upper component 2 presses the nail pressing member 14 in the lower component 1.

[0049] When the device is not in use, the limit assembly 3 in the upper assembly 2 can be pressed to make the protrusions 36 on the two elastic strips 35 in the limit assembly 3 engage with the two limit holes in the movable hole 25 of the upper assembly 2 respectively. At the same time, the first fixing rod 31 in the limit assembly 3 extends downward to contact the lower assembly 1 to prevent the device from being accidentally triggered when other people touch the device.

[0050] When the device needs to be used again, the limit assembly 3 is rotated counterclockwise to separate the protrusion 36 in the limit assembly 3 from the limit groove 27, and the limit assembly 3 can be automatically reset by the spring arranged inside. The user then rotates the limit assembly 3 clockwise to assist the limit assembly 3 in restoring the initial position.

[0051] When the device is in use and the nails in the nail magazine structure 4 are used up and need to be replaced, the magazine box 41 can be directly pressed to make the magazine box 41 and the second fixing rod 432 in the connecting member 43 slide into the first mounting groove 15 at the same time. When the second fixing rod 432 slides, the double-headed cone block 437 will be pushed through the circular through hole 433 in the third fixing plate 431 via the second limiting ring 436. When the magazine box 41 is directly released after pressing the magazine box 41, the magazine box 41 will move to the outside of the first mounting groove 15 due to the thrust of the two springs inside the first mounting groove 15, and pull the second fixing rod 432. At the same time, the two cones on the second fixing rod 432 are pulled out of the second mounting groove 16 through the circular through hole 433, so that the magazine box 41 can be easily taken out.

[0052] After the nails in the magazine 41 are replenished, the magazine 41 is directly installed into the first installation groove 15, and the magazine 41 can be automatically fixed and installed by the connecting member 43, so that the nails in the magazine 41 can be replaced very conveniently.
