[0035] In a specific embodiment, the system for implanting multiple nails with wires with a magazine provided by the present invention includes a puncher, a pusher, and a magazine nail gun. The puncher can be a drill or a punch, and the punch usually has a point at one end, and its material can be stainless steel or titanium alloy; the pusher usually includes a pusher body 21 and a pusher head 22, and the length of the pusher is greater than the barrel 1.

[0036] The cartridge nail gun includes a gun barrel 1 and a nail cartridge 2. The gun barrel 1 is provided with a nail channel 6 and a punching channel 5. The nail channel 6 is used to pass the wire nail 9. Specifically, the pusher sends the wire nail 9 from the outer end to the inner end of the nail channel 6. The punching channel 5 is used to pass the puncher. The two can be two different channels or the same channel. The diameter range of the nail channel 6 and / or the punching channel 5 is 1.5-15 mm, which is suitable for different types of punchers and pushers. The hole formed by the nail channel 6 and / or the punching channel 5 can be a circular hole, a square hole, or a regular polygonal hole. For the purpose of convenient processing, the cross section of the hole is preferably a circular hole, a square hole, or a regular polygonal hole.

[0037] The nail magazine 2 is arranged at the tail of the barrel 1, that is, the position of the barrel tail 4, and it can be fixedly connected to the barrel 1 or slidably connected. In addition, the outer end surface of the nail magazine 2 can be located in the same plane as the outer end surface of the barrel tail 4, that is, the outer ends of the two are flush, and can also be located in different planes, that is, the nail magazine 2 is arranged within a certain distance range from the barrel tail 4.

[0038] The head of the gun barrel 1, i.e., the gun barrel head 3, is provided with a positioning tip 8, which is usually provided on the inner end surface of the gun barrel head 3, and may be provided with one, two or more positioning tips 8, and is used to fix the gun barrel 1 at the fracture site to prevent it from sliding during use. For ease of use, a handle for easy gripping may also be provided on the outside of the gun barrel 1.

[0039] The outer end or inner end mentioned above are relative, the end closer to the wound is the inner end, and the opposite end is the outer end.

[0040] A plurality of staples 9 with threads are arranged in the staple magazine 2, which are connected in sequence through sutures 10. Specifically, the staple magazine 2 can be a square magazine or a circular magazine, and the staples 9 with threads can be arranged side by side or separately.

[0041] The invention provides a system for implanting multiple wire-carrying nails with a magazine, which comprises a puncher, a pusher and a magazine-type nail gun. When a bone fracture, detachment or rupture of a ligament or tendon occurs, the free bone, ligament or tendon is first reset, and then the nail gun of the system for implanting multiple wire-carrying nails with a magazine is sent through an incision to the part that needs to be fixed, and the nail gun is fixed with a positioning tip of the nail gun head to prevent sliding, and then a matching puncher is used to drill a nail channel under the guidance of a punching channel. After the drilling of the nail channel is completed, the pusher is operated to allow each of the wire-carrying nails to pass through the nail channel and be implanted into the nail channel.

[0042] The wire nail and the suture are fixed by utilizing the interference fit between the wire nail and the nail channel, and then the pusher is pulled out. Next, the nail gun head is translated to the second fixed position along the bone surface or the soft tissue surface. The second wire nail is implanted by the same operation. While implanting, the suture is pulled by hand. The suture connecting the two wire nails is tightened as the wire nail is implanted into the nail channel, thereby achieving fixation between bone blocks or between soft tissue and bone.

[0043] The above-mentioned system for implanting multiple nails with wires with a magazine sets multiple nails with wires on the same nail gun, so that it is convenient to implant multiple nails with wires into the fracture site in sequence. The nail channels can be drilled and the nails with wires can be implanted continuously. There is no need to thread sutures in sequence and there is no need to open multiple holes in the skin. Therefore, the difficulty of surgery can be reduced, the cost of surgery can be reduced, and the efficiency of surgery can be improved.

[0044] In a specific embodiment, the nail channel 6 and the punching channel 5 are the same channel. Figure 8 and Fig. 9In this case, the gun barrel 1 may be a cylindrical gun barrel, and a nail magazine axis 13 is provided at the gun barrel tail 4, which is arranged parallel to the gun barrel 1. In this case, the nail magazine 2 is a circular ring magazine, which is sleeved on the outside of the nail magazine axis 13 and can rotate around its axial direction. Each of the threaded nails 9 in the nail magazine 2 is located in a different nail hole, and each of the nail holes is usually evenly arranged around the nail magazine 2. When the nail magazine 2 rotates axially around the nail magazine axis 13, each of the nail holes can overlap with the nail channel 6, so each of the threaded nails 9 can enter the nail channel 6 under the action of the pusher.

[0045] It should be noted that the nail holes in the nail magazine 2 can not only be set with wire nails 9 but also pass through pushers and punchers. In addition, since the wire nails 9 need to be punched before entering the nail channel 6, one of the nail holes needs to be vacant, that is, the number of nail holes is one more than the number of wire nails 9. According to the specific situation, the position of the vacant nail hole can be fixed and set as a special channel for the puncher, or all nail holes can be set to the same specification and one can be randomly selected as vacant.

[0046] In a specific embodiment, the nail channel 6 and the punching channel 5 are channels independently arranged from each other, that is, two different channels. Usually, a movable partition 7 is arranged in the gun barrel 1, and the partition 7 divides the inside of the gun barrel 1 into the nail channel 6 and the punching channel 5. At this time, the gun barrel 1 is mostly a conical circular tube, and the inner and outer diameters of the gun barrel tail 4 are larger than the inner and outer diameters of the gun barrel head 3. Correspondingly, the surgical incision can also be reduced, thereby reducing the harm to the patient.

[0047] The partition 7 is usually an elastic sheet that can be moved to change the size of the hole formed by the nail channel and the punch channel. Specifically, the outer end of the partition 7 can be fixedly connected to the barrel tail 4 and is generally located in the middle of the inner hole of the barrel tail 4, while its inner end is not connected to the barrel head 3, that is, the AB section of the partition 7 is fixed and the BC section is movable, so when the punch is inserted into the punch channel 5 or the pusher is inserted into the nail channel 6, the inner diameters of the nail channel 6 and the punch channel 5 can be changed as the partition 7 moves.

[0048] On the basis of the above embodiment, there are two ways to connect the nail magazine 2 and the gun barrel 1, one is fixed connection, the other is movable connection, which can be set to be detachable connection, specifically sliding connection. When fixed connection, the structure of the nail magazine 2 is relatively simple, and when movable connection, the storage of the wire nail 9 is relatively convenient. However, no matter which connection method is used, the nail magazine 2 is connected to the nail channel 6, so that the wire nail 9 can enter the nail channel 6.

[0049] Specifically, when the nail magazine 2 is fixedly connected to the gun barrel 1, as shown in FIG. Figure 1, which is usually arranged at one side of the nail channel 6 and connected thereto, in this case, the nail magazine 2 can be a square three-dimensional structure and arranged vertically to the gun barrel 1, so that it is convenient for each wire nail 9 to be arranged side by side in the nail magazine 2, and then a compression spring is arranged at the bottom of the nail magazine 2 to automatically send the wire nail 9 into the connection between the nail channel 6 and the nail magazine. In this case, there is no need to set a special nail hole for placing the wire nail, and the structure is the simplest.

[0050] Of course, the nail magazine 2 can also be a three-dimensional structure of other shapes, as long as the threaded nails 9 can enter the nail channels 6.

[0051] When the nail magazine 2 and the gun barrel 1 are in sliding connection, the nail magazine 2 and the nail channel 6 are still connected, and as the relative positions of the nail magazine 2 and the gun barrel 1 move, each of the threaded nails 9 can enter the nail channel 6. Specifically, the nail magazine 2 can be configured as follows:

[0052] For example, Figure 3 , Figure 4 and Figure 5 The nail magazine 2 is a square magazine, and each wire nail 9 in the nail magazine 2 is set in a corresponding nail hole. The nail magazine 2 slides up and down in a direction perpendicular to the barrel 1. During the sliding process of the nail magazine 2 along the barrel 1, there is a nail hole that can coincide with the nail channel 6.

[0053] In addition, if Figure 6 and Figure 7 The nail magazine 2 can be a circular ring magazine, and each wire nail 9 in the nail magazine 2 is set in the corresponding nail hole. The nail magazine 2 is sleeved on the outside of the punching channel 5 and can rotate axially around the punching channel 5. During the sliding process of the nail magazine 2, one nail hole can coincide with the nail channel 6.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0055] The above is a detailed introduction to the multiple-wire nail implantation system with a magazine provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
