Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a nail magazine assembly of a linear cutting closer. Background Art
[0002] In the modern medical field, linear cutting and sealing devices are an important surgical instrument and are widely used in various surgeries, especially in gastrointestinal and other digestive tract surgeries, where they play a vital role in tissue resection, transection and anastomosis. Traditional surgical methods are often complicated and time-consuming, which brings great inconvenience to doctors and patients.
[0003] At present, there are many types of linear cutting closure nail magazine components on the market, but most products still need to be improved in terms of operational convenience and functional perfection. In particular, in terms of clamping the patient's internal tissue, anti-slip and titanium nail guidance, traditional products often find it difficult to achieve ideal results. Therefore, in order to solve the above problems, we propose a linear cutting closure nail magazine component. Utility Model Content
[0004] The utility model aims to solve the defects in the prior art and proposes a linear cutting closer nail magazine assembly.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A linear cutting closer nail magazine assembly comprises a nail magazine, a knife groove is provided inside the nail magazine, a plurality of nail grooves are provided inside the nail magazine, and the plurality of nail grooves are equidistantly arranged on both sides of the knife groove. The invention is characterized in that a detachable hook head is installed at the front end of the nail magazine, guide blocks are fixedly installed on both sides of the top of the nail groove, and anti-slip protrusions are fixedly installed on both sides of the top of the nail magazine at equal distances.
[0007] Furthermore, a screw is fixedly installed on one side of the hook head close to the nail magazine, a threaded hole is opened at the front end of the nail magazine, and the screw is threadedly installed inside the threaded hole.
[0008] Furthermore, the opposite sides of the two guide blocks at the top of the nail groove are both inclined surfaces, and the distance between the two inclined surfaces gradually decreases from the lower right to the upper side.
[0009] Furthermore, a plurality of arc-shaped plates are fixedly installed at equal distances on both sides of the interior of the knife groove.
[0010] Furthermore, the anti-slip protrusion is a triangular structure.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] After the nail magazine contacts the tissue, the guide block and anti-slip protrusion on the top of the nail magazine can be embedded in the tissue to increase the friction between the nail magazine and the tissue and prevent the tissue from falling off. Medical staff can quickly install or remove the hook head as needed, which is convenient for doctors to quickly and accurately extend the nail magazine into the tissue to hook and clamp the tissue to be cut during surgery. At the same time, the shape and size of the hook head have various specifications and can be adjusted according to different surgical needs to adapt to the clamping of different tissues.
[0013] The guide block of the utility model can squeeze the titanium nail so that the top end of the titanium nail is deformed inwardly, so that after the top end of the titanium nail contacts the nail anvil, the top end of the titanium nail can be accurately squeezed and bent inwardly, avoiding the situation where part of the titanium nail is bent outwardly due to position deviation, resulting in suturing failure.
[0014] When the cutter moves along the inside of the cutter groove, the arc-shaped plate of the utility model can squeeze the cutter from both sides of the cutter, so that the cutter remains stable during the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0022] Reference Figure 1-4A linear cutting closer nail magazine assembly includes a nail magazine 1, a knife groove 4 is opened inside the nail magazine 1, a plurality of nail grooves 3 are opened inside the nail magazine 1, and the plurality of nail grooves 3 are equidistantly arranged on both sides of the knife groove 4, a detachable hook head 2 is installed at the front end of the nail magazine 1, guide blocks 6 are fixedly installed on both sides of the top of the nail groove 3, and anti-slip protrusions 5 are fixedly installed at equidistant distances on both sides of the top of the nail magazine 1, and the anti-slip protrusions 5 are triangular structures.
[0023] The nail magazine 1 can be installed inside the nail magazine seat of the linear cutting and closing device, and titanium nails are arranged inside the nail groove 3. When the linear cutting and closing device is used to clamp the tissue in the patient's body, the linear cutting and closing device can be operated to make the cutter enter the knife groove 4. The cutter can move along the knife groove 4 to cut the clamped tissue and at the same time push out the titanium nails inside the nail groove 3 so that the titanium nails are nailed into the tissue to achieve cutting and suturing.
[0024] After the nail magazine 1 contacts the tissue, the guide block 6 and the anti-slip protrusion 5 on the top of the nail magazine can be embedded in the tissue to increase the friction between the nail magazine 1 and the tissue to prevent the tissue from falling off. Medical personnel can quickly install or remove the hook head as needed, which is convenient for doctors to quickly and accurately extend the nail magazine 1 into the tissue to hook and clamp the tissue to be cut during surgery. At the same time, the shape and size of the hook head have various specifications and can be adjusted according to different surgical requirements to adapt to the clamping of different tissues.
[0025] A screw rod 9 is fixedly installed on one side of the hook head 2 close to the nail magazine 1, and a threaded hole 8 is opened at the front end of the nail magazine 1. The screw rod 9 is threadedly installed inside the threaded hole 8. The hook head 2 can be installed at the front end of the nail magazine 1 through the screw rod 9 and the threaded hole 8, and the hook head 2 can be installed and removed by rotating the hook head 2.
[0026] The opposite sides of the two guide blocks 6 at the top of the nail groove 3 are both inclined surfaces, and the distance between the two inclined surfaces gradually decreases from the lower right to the upper side. The width of the nail groove 3 is slightly larger than the width of the titanium nail. When the titanium nail is pushed out from the inside of the nail groove 3, the top of the titanium nail will contact the inclined surface of the guide block 6, and the guide block 6 will squeeze the titanium nail, causing the top of the titanium nail to deform inward. Therefore, after the top of the titanium nail contacts the nail anvil, the top of the titanium nail can be accurately squeezed and bent inward, avoiding the situation where some titanium nails bend outward due to position displacement, resulting in suture failure.
[0027] A plurality of arc plates 7 are fixedly installed at equal distances on both sides of the knife groove 4. When the cutter moves along the inside of the knife groove 4, the arc plates 7 can squeeze the cutter from both sides of the cutter to keep the cutter stable during the cutting process.
