Abstract
Description
Technical Field
[0001] The utility model relates to a stapler assembly, in particular to a split stapler magazine assembly. 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 existing staplers have the following problems: in order to enable the stapler to be inserted into the skin and facilitate medical personnel to remove obstructing internal organs or other free tissues, an integrated guide head with a pointed tip is provided at the end of the existing stapler assembly. However, such a stapler assembly with an integrated guide head is very inconvenient for medical personnel. Medical personnel need to prepare stapler assemblies of various specifications before surgery, and the prepared stapler assemblies with guide heads may not be used during surgery, which not only increases the workload of medical personnel, but also occupies the already small preoperative instrument reserve space, squeezing out the space for other more needed instruments.
[0004] In order to solve the above problems, a detachable nail magazine assembly has also appeared in the existing market. The nail magazine assembly and the guide head are detachably connected, but the existing guide head is relatively small in size and has no good fulcrum. Therefore, it is very difficult for medical staff to install or remove the guide head by hand. Therefore, medical staff need auxiliary tools to quickly install and remove the guide head. Chinese patent application number 2023203779680 discloses a multifunctional auxiliary disassembly and assembly device for anastomosis.
[0005] However, the above patent still has the following problems: medical staff need to prepare additional auxiliary disassembly and assembly devices, which increases the preparation workload of medical staff, squeezes the preoperative equipment storage space, and the disassembly and assembly during the operation also takes a certain amount of time. Moreover, due to the tense operation process, the guide head may rupture during the tense disassembly and assembly process, posing a hidden danger to the patient's surgical safety. Summary of the invention
[0006] Purpose of the utility model: The purpose of the utility model is to provide a split nail magazine assembly that is easy to disassemble and assemble the guide head.
[0007] Technical solution: The utility model discloses a detachable nail magazine assembly, comprising a nail magazine and a guide head, wherein a guide slope is arranged at the rear end of the nail magazine, and an insertion groove is provided on the guide head for inserting the rear end of the nail magazine, and the cross section of the insertion groove matches the cross section of the rear end of the nail magazine.
[0008] Furthermore, a limiting protrusion is arranged in the insertion groove, and a limiting groove for limiting the limiting protrusion is arranged at the rear end of the nail magazine.
[0009] Furthermore, an expansion seam is provided at the top of the guide head, the expansion seam is communicated with the insertion slot, and the upper end surface of the expansion seam passes through the upper end surface of the top of the guide head. The expansion seam has two functions: 1. When the tail end of the nail magazine is inserted into the guide head, the top of the nail magazine may abut against the top of the guide head. If the expansion seam is not provided, the guide head may be broken and scrapped by the nail magazine. The expansion seam is used to actively deform when the nail magazine abuts against the guide head to prevent the guide head from being broken; 2. When the guide head is to be disassembled, the tail end of the nail magazine must be separated from the limit of the limit protrusion. During the separation process, the tail end of the nail magazine may abut against the top of the guide head, thereby breaking the guide head. The expansion seam can prevent the guide head from being broken during the disassembly process.
[0010] Further, the expansion seam is arranged in the middle of the top of the guide head.
[0011] Furthermore, one end of the expansion slot facing the nail magazine passes through the end surface of the guide head facing the nail magazine.
[0012] Furthermore, a through hole is provided on the top of the guide head, and the through hole is communicated with the expansion slot. The through hole is used to assist the deformation of the expansion slot and prevent the expansion slot from cracking during the deformation process.
[0013] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. The nail magazine and the guide head in the utility model are detachably connected. When the guide head is needed, the medical staff only needs to manually insert the nail magazine into the guide head. The medical staff only needs to prepare nail magazines of various specifications, saving preoperative instrument storage space; 2. The utility model is very convenient to disassemble and assemble. When the guide head is needed, it is only necessary to insert the nail magazine into the guide head along the insertion slot. When disassembling, it is only necessary to form a certain angle between the guide head and the nail magazine so that the nail magazine is out of the limit of the limit protrusion. The operation is simple and convenient for medical staff, and no other devices are needed, saving preoperative instrument storage space. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.
[0021] See attached Figure 1 to Figure 5 A detachable nail magazine assembly shown in the utility model includes a nail magazine 2 and a guide head 1.
[0022] The guide head 1 is provided with an insertion slot 101 for inserting the tail end of the nail magazine 2, a limiting protrusion 102 is arranged in the insertion slot 101, an expansion slot 104 is arranged at the center of the top of the guide head 1, the expansion slot 104 is communicated with the insertion slot 101, and the upper end surface of the expansion slot 104 passes through the upper end surface of the top of the guide head 1, and the end of the expansion slot 104 facing the nail magazine 2 passes through the end surface of the guide head 1 facing the nail magazine 2; a through hole 103 is arranged on the top of the guide head 1, and the through hole 103 is communicated with the expansion slot 104.
[0023] A guide slope 201 is provided at the rear end of the nail magazine 2 , the cross section of the insertion slot 101 matches the cross section of the rear end of the nail magazine 2 , and a limiting groove 202 is provided at the rear end of the nail magazine 2 for limiting the limiting protrusion 102 .
[0024] The expansion slit 104 has two functions. First, when the tail end of the nail magazine 2 is inserted into the guide head 1, the top of the nail magazine 2 may abut against the top of the guide head 1. If the expansion slit 104 is not provided, the guide head 1 may be broken and scrapped by the nail magazine. The expansion slit 104 is used to actively deform when the nail magazine 2 abuts against the guide head 1 to prevent the guide head 1 from being broken. Second, when the guide head 1 is to be disassembled, the tail end of the nail magazine 2 must be separated from the limit of the limit protrusion 102. During the separation process, the tail end of the nail magazine 2 may abut against the top of the guide head 1, thereby breaking the guide head 1. The expansion slit can prevent the guide head 1 from being broken during the disassembly process. The through hole 103 is used to assist the deformation of the expansion slit 104 to prevent the expansion slit 104 from breaking during the deformation process.
