Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a solderless bipolar electrocoagulation forceps. Background Technology
[0002] Bipolar electrocoagulation delivers high-frequency electrical energy to the diseased tissue through the two tips of bipolar forceps, causing the bleeding point between the two ends of the forceps to dehydrate and coagulate, thus achieving hemostasis. Because its effect is limited to the area between the two forceps tips, the damage and impact on adjacent tissues are minimal, making it quite safe. Currently, in traditional bipolar electrocoagulation forceps, the conductive plates of the forceps body are often connected to the wires using soldering. However, this method has the following drawbacks:
[0003] 1. The installation process is rather complicated, increasing production difficulty and time;
[0004] 2. Welding costs are high, which is not conducive to mass production and automated assembly;

[0015] Furthermore, anti-slip textures are provided on the opposite sides of both tweezers.
[0016] Furthermore, each of the two tweezers has a clearance groove on one side of its opposite side for pre-embedding a drip pipe.

[0038] Example 1
[0039] like Figure 1-5 As shown, an embodiment of this utility model provides a solderless bipolar electrocoagulation tweezers. The bipolar electrocoagulator can be tweezers or clamps. The description and drawings of this embodiment are based on the tweezers structure, but the improvement is also applicable to the clamps. It should be noted that the electrical parts and working principle of the electrocoagulation tweezers can be referred to the existing structure. This embodiment does not describe this, but only describes the structural improvements made to the electrocoagulation tweezers in detail.
[0040] Specifically, in this embodiment of the present invention, the solderless bipolar electrocoagulator includes two opposingly distributed tweezers 10 and a tweezers base 20. Each tweezers 10 includes a discharge end 11 and a conductive end 12 arranged opposite to each other. The conductive ends 12 of both tweezers 10 are connected to the tweezers base 20, so that the discharge ends 11 of the two tweezers 10 can be relatively close or far apart. The tweezers base 20 includes: two mounting grooves 21, which are opened on the left and right sides of the tweezers 10 and adapted to the conductive ends 12 of the tweezers 10, for mounting the conductive ends 12 of the two tweezers 10; and two wire pressing grooves 22, which are respectively opened on the two mounting grooves 21, for pressing the conductive part 31 of the wire 30. By installing the conductive ends 12 of the tweezers 10 in the mounting grooves 21, the conductive part 31 of the wire 30 placed in the wire pressing grooves 22 is pressed.
[0041] In this embodiment of the invention, by placing the conductive part 31 (exposed metal part) of the wire 30 into the wire-pressing groove 22 on the tweezers base 20, ensuring that the conductive part 31 is completely located within the wire-pressing groove 22, the conductive end 12 of the tweezers body 10 can then be placed into the mounting groove 21 of the tweezers base 20. This ensures an interference fit between the conductive end 12 and the mounting groove 21, improving the stability of the connection between the tweezers body 10 and the tweezers base 20, while simultaneously ensuring that the conductive end 12 fully presses against the conductive part 31 located within the wire-pressing groove 22. At this point, the conductive part 31 is firmly clamped between the conductive end 12 of the tweezers body 10 and the wire-pressing groove 22, thereby enabling a quick and stable connection between the tweezers body 10 and the wire 30. This avoids problems such as material damage, operational complexity, and weak welding that occur in traditional welding processes, simplifying the assembly process, effectively reducing production time, and improving production efficiency.
[0042] Specifically, such as Figure 4 As shown, the depth of the wire pressing groove 22 is less than the thickness of the conductive part 31 of the wire 30. Since the conductive part 31 of the wire 30 will slightly protrude from the groove opening, the conductive end 12 of the tweezers 10 can directly apply pressure to the conductive part 31, thereby achieving a tighter pressing connection. This makes it less likely for the conductive part 31 of the wire 30 to slide or shift in the groove, ensuring the reliability of the connection. Furthermore, since the depth of the wire pressing groove 22 is shallower, the conductive part 31 is subjected to a higher degree of compression, thereby increasing the contact area between the conductive part 31 and the conductive end 12 of the tweezers 10, so that the conductive part 31 of the wire 30 can better contact and conduct electricity with the conductive end 12 of the tweezers. The depth of the wire pressing groove 22 is 2 / 3 of the thickness of the conductive part 31 of the wire 30 (pre-compression 1 / 3).
[0043] Based on the above solutions, such as Figure 3-4 As shown in this embodiment of the utility model, the tweezers 10 has two wire-passing grooves 23 on its upper and lower sides, and the wire-passing grooves 23 are connected to the wire-pressing grooves 22 for placing the wires 30. The wire-passing grooves 23 provide a fixed and guiding position for the wires 30, preventing the wires 30 from affecting the connection of the conductive part 31 in the wire-pressing grooves 22 due to pulling or moving during use. The connection between the wire-passing grooves 23 and the wire-pressing grooves 22 enables rapid wiring and installation of the wires 30.
[0044] Secondly, the cable tray 23 has an L-shaped structure, and the inner wall of the cable tray 23 has rounded corners at its corners. The L-shape restricts the movement direction of the wire 30, making the wire 30 more stable in the cable tray 23 and less likely to slide or come out. The rounded corners make the wire 30 smoother when passing through the tray, preventing it from getting stuck or scratched, thus improving installation efficiency.
[0045] Specifically, such as Figure 2 and 5As shown, the tweezers base 20 is provided with a plurality of mounting holes 24, and the mounting holes 24 penetrate through the two mounting grooves 21; the conductive ends 12 of the two tweezers 10 are each provided with a plurality of positioning holes 121 that cooperate with the mounting holes 24. The mounting holes 24 and the positioning holes 121 are used for fasteners 40 to pass through, so as to install the conductive ends 12 of the two tweezers 10 onto the tweezers base 20. The conductive ends 12 of the tweezers 10 are fixed to the mounting grooves 21 of the tweezers base 20 by the fasteners 40, which further ensures that the conductive part 31 of the wire 30 in the wire pressing groove 22 is fully pressed, preventing it from shifting or loosening during use, reducing the risk of poor contact, and improving the stability of the connection.
[0046] In this embodiment, the fastener 40 is a positioning pin, which passes through the mounting hole 24 of the tweezers base 20 and is press-fitted with the positioning hole 121 of the conductive part 31, thereby firmly fixing the conductive end 12 of the tweezers body 10 in the mounting groove 21 of the tweezers base 20, thereby further pressing the conductive part 31 of the wire 30 in the wire pressing groove 22, achieving a fast and stable installation effect.
[0047] Based on the above solutions, such as Figure 1-2 As shown, in order to prevent the forceps 10 from slipping due to hand sweat, liquid contact or prolonged use during operation, so that the operator can more accurately control the opening and closing of the forceps 10 and the operating force, hold it more firmly, and improve surgical accuracy, in this embodiment of the utility model, anti-slip textures 13 are provided on the opposite sides of the two forceps 10. Specifically, the anti-slip textures 13 are wavy.
[0048] Based on the above solutions, such as Figure 5 As shown in this embodiment of the invention, each of the two forceps bodies 10 has a recessed groove 14 on one side for pre-embedding a drip tube 50. By installing the drip tube 50 in the recessed groove 14, the drip tube 50 allows the bipolar electrocoagulation forceps to have a flushing effect when performing electrocoagulation and hemostasis on the wound, thereby reducing the heat generated during electrocoagulation and reducing the adhesion of electrocoagulated tissue to the discharge end 11 of the bipolar electrocoagulation forceps, which affects its use. Secondly, recessed cavities 25 communicating with the mounting groove 21 are also provided on the left and right sides of the forceps base 20. The recessed cavity 25 and the recessed groove 14 together form an installation channel to facilitate the arrangement of the drip tube 50 and also to keep the drip tube 50 in a fixed position during use, avoiding loosening of the connection due to movement.
[0049] Specifically, in this embodiment of the invention, the tweezers base 20 is made of PEEK, which gives it excellent high-temperature resistance, electrical insulation, and corrosion resistance, as well as high mechanical strength.
[0050] Based on the above solutions, such as Figure 1-2 As shown in this embodiment of the present invention, a housing 60 is also provided on the conductive parts 31 of the tweezers base 20 and the two tweezers bodies 10 to increase insulation and safety of use. Furthermore, a clearance hole is provided on the housing 60 for the drip pipe 50 or the wire 30 to pass through, thereby facilitating operation and maintenance.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
