Technical Field
[0001] The utility model relates to the technical field of bipolar electrocoagulation forceps, in particular to a pair of bipolar electrocoagulation forceps. Background Art
[0002] Bipolar electrocoagulation forceps are important surgical instruments, mainly used for local electrocoagulation hemostasis of bleeding points. Its working principle is to use a high-frequency power supply that is completely isolated from the ground, so that it is released at the two tips of the bipolar electrocoagulation forceps, thereby producing a thermal effect on the human tissue between the electrocoagulation forceps, causing the local temperature to rise, and gradually causing tissue degeneration, necrosis, drying, gasification, and carbonization, so as to achieve hemostasis and separation, thereby coagulating the protein in the blood and achieving a hemostatic effect. This hemostasis method not only has a fast hemostasis speed, good hemostasis effect, but also less damage. At present, conventional bipolar electrocoagulation forceps on the market mainly include a pair of forceps bodies, an electrode seat for power supply, a wire, and a power supply, etc.; wherein, the front section of the forceps body is a rod-shaped forceps rod and a forceps tip, and the rear section is a sheet-shaped forceps handle. The one-piece molding method is used during processing, so that the overall structural strength of the forceps body is higher and more durable. However, the one-piece structural design of the forceps body also makes processing difficult, especially the forceps tip part, which often needs to be manually polished and trimmed in the later stage, which is time-consuming and labor-intensive. Due to the existence of processing errors, the two forceps tips are often misaligned, affecting use. Utility Model Content

[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0031] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a bipolar electrocoagulation forceps, including: a forceps rod 1, one end of which is provided with a forceps tip 2, and the other end is provided with a first connection structure; a forceps handle 3, one end of which is provided with a second connection structure adapted to the first connection structure, and the forceps handle 3 is arranged on the forceps rod 1 through the first connection structure and the second connection structure; wherein the forceps rod 1 and the forceps handle 3 are arranged in pairs. The first connection structure and the second connection structure can be connection structures designed based on plug-in connection, mortise and tenon connection, screw connection, snap-on connection, etc., with the purpose of enabling the forceps rod 1 and the forceps handle 3 to be assembled together after independent processing.
[0032] In the bipolar electrocoagulation forceps provided in this embodiment, the forceps rod 1 and the forceps handle 3 are two independent components, which are assembled and connected by a first connecting structure and a second connecting structure. The forceps rod 1 and the forceps handle 3 can be processed by different processes respectively, which reduces the processing difficulty; for example, the forceps rod 1 can be processed by a turning and milling process that is more suitable for a rod-like structure, and the forceps handle 3 can be formed by a stamping process that is more suitable for a plate-like structure. Moreover, for the forceps tip 2, it can be processed together when the forceps rod 1 is processed by a machine tool, avoiding manual secondary trimming at a later stage, saving time and labor, and helping to reduce processing errors and avoid misalignment of the two forceps tips 2 after assembly.
[0033] The first connection structure may be a recessed portion 7 disposed on the tweezers rod 1, and the second connection structure may be a protruding portion 6 disposed on the tweezers handle 3, and the tweezers rod 1 and the tweezers handle 3 are plug-in connected via the recessed portion 7 and the protruding portion 6. For example, the recessed portion 7 may be a groove-shaped or hole-shaped structure, and the protruding portion 6 may be a columnar or block-shaped structure, and the connection between the tweezers rod 1 and the tweezers handle 3 is achieved through the convex-concave fit.
[0034] For example, the recess 7 can be provided at the end of the forceps rod 1, and correspondingly, the protrusion 6 is also provided at the end of the forceps handle 3, in which case the forceps rod 1 and the forceps handle 3 are plugged in along the axial direction. For another example, the recess 7 can be provided on the side wall of the forceps rod 1 near the end, and correspondingly, the protrusion 6 is provided on the side wall of the forceps handle 3 near the end, in which case the forceps rod 1 and the forceps handle 3 are plugged in along the radial direction.
[0035] like Figure 4 , Figure 5 as well as Figure 6 As shown, the bipolar electrocoagulation forceps further include a limiting plug-in 4 and a limiting slot 5; the limiting plug-in 4 is arranged on one of the forceps handles 3, and the limiting slot 5 is arranged on the other forceps handle 3. When the two forceps handles 3 are close to each other, the limiting plug-in 4 is inserted into the limiting slot 5 to limit the movement of the two forceps handles 3 that causes the forceps tips 2 to be misaligned. For example, the main body of the limiting plug-in 4 can be a plate-like structure, a columnar structure is arranged on the plate surface, and the main body of the limiting slot 5 can be a plate-like structure, a U-shaped groove structure is arranged on the plate surface, and an annular groove structure can also be arranged on the plate surface. When the user squeezes the two forceps handles 3 with force, the columnar structure is inserted into the U-shaped groove structure. At this time, the two forceps handles 3 can only perform specific movements within the space defined by the limiting slot 5 and the limiting plug-in 4, that is, the two forceps handles 3 can only approach or move away from each other, thereby ensuring that the two forceps tips 2 can only approach or move away from each other to avoid misalignment.
[0036] like Figure 7As shown, the bipolar electrocoagulation forceps further includes a slot support 9; the main body of the slot support 9 can be a plate-shaped structure, and a plurality of connecting columns 11 are arranged on the plate surface, and the slot support 9 is embedded in the forceps handle 3 adapted by the limiting slot 5 through the connecting columns 11; the limiting slot 5 is arranged on the slot support 9. For example, two connecting columns 11 can be symmetrically arranged on the slot support 9, and such arrangement can increase the contact area between the slot support 9 and the forceps handle 3, and indirectly improve the connection strength between the limiting slot 5 and the forceps handle 3.
[0037] like Figure 8 As shown, an anti-falling hole 10 is provided on the slot support 9, and an anti-falling column 8 is provided on the side of the limiting slot 5 facing the slot support 9; the anti-falling column 8 is pluggable and arranged in the anti-falling hole 10, and when the anti-falling column 8 is inserted into the anti-falling hole 10, the anti-falling column 8 rotates along its own axis at a preset angle so that the edge of the anti-falling hole 10 is abutted against the anti-falling column 8, so as to limit the anti-falling column 8 from falling off from the anti-falling hole 10. For example, the anti-dropping hole 10 can be a long strip hole, and a cap body can be provided at the end of the anti-dropping column 8 away from the limiting slot 5, and the shape and size of the cap body are adapted to the shape and size of the anti-dropping hole 10, so that in a certain direction, the cap body of the anti-dropping column 8 can pass through the anti-dropping hole 10 normally, and after the anti-dropping column 8 is inserted into the anti-dropping hole 10, once the anti-dropping column 8 is rotated, the cap body on the anti-dropping column 8 can be abutted against the edge of the anti-dropping hole 10, so that the anti-dropping column 8 cannot be pulled out of the anti-dropping hole 10. Among them, the preset angle described in the above embodiments can be 30°, 45°, 90°, etc.
[0038] There is an adhesive between the contact surface of the limit plug 4 and the tweezers handle 3, and an adhesive between the contact surface of the slot support 9 and the tweezers handle 3. For example, the adhesive can be glue, or metal welding liquid, etc., in order to improve the strength of the connection.
[0039] like Fig. 9 As shown, the surface of the tweezers rod 1 is provided with a plastic insulating layer 12 so that the current is released only at the tweezers tip 2 .
[0040] The bipolar electrocoagulation forceps further include a silicone wrapping layer 13, which is arranged on the outside of the forceps handle 3 to wrap the forceps handle 3 therein. Such a configuration can not only achieve an insulating effect but also improve the comfort of holding.
[0041] It should be noted that the bipolar electrocoagulation forceps in the present application also include wires, electrode holders, power supplies, etc., which are all existing technologies known to those skilled in the art and will not be described in detail here.
[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
