Furthermore, the cooperation of the positioning holes and mounting holes makes the assembly process of the forceps handles and the forceps base simpler and faster.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bipolar electrocoagulation forceps for preventing misalignment. Background Technology

[0002] Bipolar electrocoagulation uses the two tips of bipolar forceps to deliver high-frequency electrical energy to the diseased tissue, causing the bleeding point between the two ends of the forceps to dehydrate and coagulate, thereby achieving the purpose of hemostasis. Since its range of action is limited to the area between the two forceps tips, the degree of damage and impact on adjacent tissues is very small, making it quite safe. When it is not energized, it can also be used as ordinary medical forceps.

[0003] Currently, traditional bipolar electrocoagulation forceps suffer from poor fixation at the tails of the two forceps, which can easily lead to inaccurate positioning and misalignment of the forceps tips during use. This is especially noticeable with forceps that have finer tips, making it difficult for surgical operators to make accurate cuts and increasing the difficulty of delicate operations.

The mounting holes and the positioning holes are used for fasteners to pass through, so as to fix the conductive ends of the two tweezer handles on the tweezer base.

[0007] Furthermore, the tweezers base has grooves on both sides that are adapted to the conductive end, and the mounting hole passes through the grooves.

[0008] Furthermore, it also includes a housing, which is fitted onto the tweezers base and the two conductive ends; the tweezers base is provided with a potting hole, and the potting hole extends through the tweezers base;

[0009] By filling the potting hole with glue, the two discharge terminals, the tweezers holder, and the outer shell are encapsulated.

[0010] Furthermore, a positioning post is provided on the inner side of the outer casing, and the positioning post is inserted into the potting hole.

[0011] Furthermore, the end of the conductive terminal has a guide bevel.

[0012] Furthermore, one of the two tweezer handles is provided with a positioning groove, and the other of the two tweezer handles is provided with a positioning protrusion that can be inserted and engaged with the positioning groove.

[0013] Furthermore, the inner contour of the positioning groove is elliptical, and the outer contour of the corresponding positioning protrusion is elliptical.

[0014] Furthermore, the tweezers base is provided with a wire passage groove for accommodating the power supply line, and the conductive end of each tweezers handle is electrically connected to the power supply line.

[0015] Furthermore, each of the two tweezer handles has a clearance groove on its opposite side for pre-embedding a drip pipe.

[0034] Example 1

[0035] like Figure 1-6 As shown, an embodiment of this utility model provides a bipolar electrocoagulation forceps to prevent misalignment. 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 forceps can be referred to the existing structure. This embodiment does not describe this, but only describes the structural improvements made to the electrocoagulation forceps in detail.

[0036] Specifically, in this embodiment of the present invention, the anti-dislocation bipolar electrocoagulation forceps includes two oppositely distributed forceps handles 10 and forceps bases 20. Each forceps handle 10 includes a discharge end 11 and a conductive end 12 arranged opposite to each other. The conductive end 12 of each forceps handle 10 is connected to the forceps base 20, so that the discharge ends 11 of the two forceps handles 10 can be relatively close or far apart. That is, by supplying power to the forceps base 20, the discharge ends 11 can be used to electrocoagulate and clamp the wound. The forceps base 20 is provided with a plurality of mounting holes 21, and the mounting holes 21 penetrate the forceps base 20. Each conductive end 12 of each forceps handle 10 is provided with a plurality of positioning holes 121 that cooperate with the mounting holes 21. The mounting holes 21 and the positioning holes 121 are used for fasteners 30 to pass through, so as to fix the conductive ends 12 of the two forceps handles 10 to the forceps base 20.

[0037] In this embodiment of the utility model, by passing fasteners 30 through several positioning holes 121 and several mounting holes 21, the conductive end 12 of the tweezer handle 10 is firmly fixed on the tweezer base 20, which avoids misalignment or inaccurate positioning of the electrocoagulation tweezers during use. At the same time, the cooperation of positioning holes 121 and mounting holes 21 makes the assembly process of tweezer handle 10 and tweezer base 20 simpler and faster.

[0038] In this embodiment, the fastener 30 is a positioning pin, which passes through the mounting hole 21 of the tweezers base 20 and is interference-fitted with the positioning hole 121 of the conductive end 12, thereby firmly fixing the conductive end 12 of the tweezers body in the mounting groove of the tweezers base 20, thus achieving a fast and stable installation effect.

[0039] Specifically, such as Figure 4 As shown in this embodiment of the present invention, the tweezers base 20 has grooves 22 on both sides that are adapted to the conductive end 12. The mounting hole 21 passes through the groove 22. The groove 22 can not only effectively guide and position the conductive end 12 of the tweezers handle 10, making the tweezers handle 10 more stable and accurate during installation, but also facilitates installation and disassembly.

[0040] In this embodiment of the invention, the groove 22 and the conductive end 12 are connected by an interference fit, so that when the conductive end 12 of the tweezer handle 10 is installed into the tweezer base 20, a certain pressure is generated, which further ensures that they fit tightly together, prevents loosening during use, and ensures the efficiency and safety of electrocoagulation operation.

[0041] Based on the above solutions, such as Figure 1-2 As shown in this embodiment of the invention, the anti-misalignment bipolar electrocoagulation tweezers further includes a housing 40, which is sleeved on the tweezer base 20 and the two conductive ends 12 to provide protection and support. The tweezer base 20 has a potting hole 23 that penetrates through it. By potting glue into the potting hole 23, the two discharge ends 11, the tweezer base 20, and the housing 40 are encapsulated, thereby effectively improving the insulation, sealing, and stability between the tweezer handle 10 and the tweezer base 20. Additionally, the housing 40... The inner side is provided with a positioning post 41, which is inserted into the potting hole 23. During the potting process, the glue flows in through the potting hole 23, and the positioning post 41 plays a guiding and fixing role to ensure that the glue is filled evenly and the sealing effect is more stable. At the same time, the positioning post 41 also forms a firm connection between the outer shell 40 and the tweezers base 20, further enhancing the stability and sealing of the structure. In addition, the end of the conductive end 12 has a guide bevel 122 so that when the conductive end 12 is installed on the tweezers base 20, the outer shell 40 is more smoothly fitted onto the tweezers base 20.

[0042] Based on the above solutions, such as Figure 5 As shown in this embodiment of the invention, a positioning groove 50 is provided on one of the two tweezer handles 10, and a positioning protrusion 60 is provided on the other of the two tweezer handles 10, which can be inserted and engaged with the positioning groove 50. By inserting the positioning protrusion 60 into the positioning groove 50, the tweezer handle 10 is precisely positioned, preventing the two tweezer handles 10 from shifting or misaligning during use. At the same time, the positioning protrusion 60 and the positioning groove 50 can limit the distance between the two tweezer handles 10 when they are closed, so that the two discharge ends 11 are not squeezed and pressed against each other to a certain extent. The pressure applied to the bipolar electrocoagulator provides some protection, preventing damage to the tweezer handles 10 or discharge ends 11 due to excessive pressure. Specifically, when the two tweezer handles 10 are brought together, the positioning protrusion 60 moves toward the positioning groove 50 until it extends into the groove and abuts against the bottom. In this state, the discharge ends 11 of the two tweezer handles 10 are close to each other without being squeezed. The inner contour of the positioning groove 50 is elliptical, and the outer contour of the positioning protrusion 60 is also elliptical.

[0043] Specifically, such as Figure 4As shown in this embodiment of the utility model, the tweezers base 20 is provided with a wire groove 24 for accommodating the power supply line 70. The conductive end 12 of each tweezer handle 10 is electrically connected to the power supply line 70. The wire groove 24 not only optimizes the routing of the power supply line 70, enabling the electrocoagulation tweezers to be connected to the power supply more stably, but also effectively avoids the line from being squeezed or pulled, thereby improving its durability and operational safety.

[0044] Based on the above solutions, such as Figure 3 As shown in this embodiment of the present invention, each of the two forceps handles 10 is provided with a recessed groove 13 for pre-embedding a drip tube 80 on one side. By installing the drip tube 80 in the recessed groove 13, the drip tube 80 enables 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.

[0045] 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.
