Description

Technical Field

[0001] The utility model relates to a stapler, in particular to a stapler capable of identifying the firing state of a staple box. Background Art

[0002] Stapler is a medical device that replaces manual suturing. Its main working principle is to use titanium nails to separate or staple tissues, similar to a stapler. Compared with traditional manual suturing, the advantages of using staplers are: 1. Simple and convenient operation, saving operation time; 2. Use titanium nails or stainless steel nails (skin staplers) to suture tightly with moderate tightness; 3. Smaller wound surface, so patients have fewer side effects and are more conducive to avoiding complications.

[0003] The stapler includes a stapler box and a body. The body is used for operation by medical staff, and the stapler box is used to provide titanium staples or stainless steel staples. In order to reduce the cost of use, a split stapler has now appeared, that is, the body and the stapler box are detachably connected. During the operation, medical staff select a stapler of corresponding specifications according to their needs, and then connect it to the body. This greatly reduces the cost of using the stapler, which is beneficial for patients to reduce the cost of seeing a doctor. However, this design has the following problems: medical staff may use multiple staplers during the operation. During the tense operation, medical staff may not be able to quickly distinguish between staplers that have been fired and staplers that have not been fired. They can only confirm whether the assembled stapler has not been fired by firing after assembly. This not only has potential risks such as unsanitary conditions and great psychological pressure on medical staff, but also may interrupt the doctor's feel, bringing considerable surgical risks to patients.

[0004] The Chinese patent with patent application number 2023104778478 discloses a stapler with an anti-misassembly function, but its structure is relatively complex, making the overall reliability relatively unstable. Summary of the invention

[0005] Purpose of the utility model: The purpose of the utility model is to provide a stapler with a relatively simple structure and capable of assisting medical personnel in quickly identifying the firing status of a staple magazine to be assembled (i.e., whether the staple magazine has been fired).

[0006] Technical solution: The utility model discloses a stapler capable of identifying the firing state of a stapler magazine, comprising a detachably connected stapler magazine assembly and a device body (the device body is used to connect to a handheld portion of a medical staff, not shown in the figure), wherein the stapler magazine assembly comprises a cylindrical stapler magazine inner core tube for inserting into the device body, a cutting knife is slidably arranged in the inner cavity of the stapler magazine inner core tube, a spring piece is arranged at the tail of the cutting knife, and the front end of the spring piece is fixedly connected to the cutting knife; an anti-misinstallation through groove is provided in the stapler magazine inner core tube, the anti-misinstallation through groove penetrates the stapler magazine inner core tube, and the position of the anti-misinstallation through groove corresponds to the position of the spring piece when the stapler magazine is not fired; a protective slider is slidably arranged on the surface of the stapler magazine inner core tube on one side close to the device body, the protective slider slides along the circumference of the stapler magazine inner core tube with the central axis of the stapler magazine inner core tube as the center, the protective slider is provided with a protective through groove, the protective through groove penetrates the protective slider, and the position of the protective through groove corresponds to the position of the spring piece when the stapler magazine is not fired.

[0007] Furthermore, a nail magazine sliding groove is provided on the tube wall of the core tube in the nail magazine, and a bottom guide block is provided at the bottom of the protective sliding block, and the bottom guide block is slidably connected to the nail magazine sliding groove.

[0008] Furthermore, the length of the protection slot is longer than the length of the anti-misinstallation slot.

[0009] Furthermore, a plurality of core tube guide blocks are arranged on the core tube in the nail magazine.

[0010] Furthermore, a plurality of introduction extension blocks are arranged on a side of the protection sliding block close to the device body.

[0011] Furthermore, a positioning bottom protrusion is arranged at the bottom of the introduction extension block, and a plurality of grooves for cooperating with the positioning bottom protrusion for positioning are arranged on the core tube in the nail magazine.

[0012] Furthermore, the nail magazine inner core tube comprises a hollow nail magazine inner core upper tube and a nail magazine inner core lower tube, and a cutting knife is slidably arranged in an inner cavity surrounded by the nail magazine inner core upper tube and the nail magazine inner core lower tube.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. The utility model has a simple structure; 2. When the cutting knife is not fired, the shrapnel is limited by the core tube in the nail magazine; when the nail magazine assembly needs to be used, the nail magazine assembly is inserted into the device body, and then the medical staff slides (can also be called rotated) the protective slider; when the cutting knife is fired, the core tube in the nail magazine gradually releases the limit on the shrapnel, and the shrapnel bounces upward; after use, the cutting knife is reset, and during the resetting process of the cutting knife, the shrapnel enters the protection groove for preventing misinstallation, and after the protection slider is reset, the shrapnel enters the protection groove, at this time, the shrapnel covers the outer wall of the core tube in the nail magazine, and the popped-up shrapnel limits the protection slider, and even if the fired nail magazine assembly is mistakenly installed again, the protection slider cannot slide again due to the limit of the shrapnel, thereby helping medical staff to quickly identify whether the nail magazine assembly has been fired.
