Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to bipolar electrocoagulation separation forceps for open surgery. Background Technology

[0002] Surgical forceps play a crucial role in surgery, serving functions such as tissue separation, clamping, traction, and hemostasis. In open surgery, energy instruments can be used to separate tissues, grasp them, and coagulate severed blood vessel ends. Currently, ultrasonic scalpels and high-frequency bipolar electrocoagulation forceps are commonly used. High-frequency bipolar electrocoagulation forceps are further divided into laparoscopic surgical electrocoagulation forceps and open surgical electrocoagulation forceps depending on the specific surgery. Bipolar electrocoagulation forceps provide high-frequency electrical energy to the body tissue through the two conductive structures of the bipolar forceps head, causing the tissue between the bipolar forceps head to electrocoagulate and the blood vessels to dehydrate and coagulate, achieving the effect of hemostasis. Its tissue electrocoagulation range is limited to between the bipolar forceps head, minimizing the risk of collateral damage caused by diffused energy. It has the advantages of good hemostasis and minimal collateral damage.

[0003] Open surgery often requires electrocoagulation and cutting of body tissues. Electrocoagulation forceps are widely used in open surgery due to their effectiveness in tissue electrocoagulation. However, some current open surgical electrocoagulation forceps have limited functionality, only capable of electrocoagulating tissue and lacking tissue cutting and separation capabilities. For example, Chinese utility model patent CN214208477U discloses an electrocoagulation hemostatic forceps for anorectal surgery. This patent is for an open surgical procedure, but it only provides hemostasis through electrocoagulation; the forceps head cannot cut or separate the electrocoagulated tissue. Therefore, some existing open surgical electrocoagulation forceps suffer from functional limitations. When cutting and separating electrocoagulated tissue is required, the surgeon must change instruments, which is cumbersome and complicates the tissue separation process, affecting the quality of the surgery. Summary of the Invention

[0004] To address the problem that existing open surgery electrocoagulation forceps have limited functionality, this invention provides a bipolar electrocoagulation separation forceps for open surgery. This bipolar electrocoagulation separation forceps is easy to operate, has a good effect on tissue electrocoagulation, and can effectively cut and separate electrocoagulated tissue. This allows the surgeon to complete the tissue electrocoagulation separation operation without changing other surgical instruments during the operation, thus improving the efficiency of the operation.

[0005] To achieve the above objectives, the technical solution of the present invention is: a bipolar electrocoagulation separation forceps for open surgery, comprising a handle portion, the front end of which is connected to an electrocoagulation forceps head, the electrocoagulation forceps head comprising a first forceps head and a second forceps head movably connected in a scissor-like manner, the handle portion comprising a first handle connected to the first forceps head and a second handle connected to the second forceps head; a blade control mechanism and a blade assembly are disposed within the first handle, the blade pushing mechanism being connected to the blade assembly, one end of the blade assembly being located within the first handle and the other end being located within the electrocoagulation forceps head; a forceps head connecting wire electrically connected to the first and second forceps heads is disposed within the second handle, the electrocoagulation forceps head being used to close and clamp tissue and electrocoagulate the tissue to achieve hemostasis through tissue electrocoagulation.

[0012] Furthermore, the inner plate is also provided with a limiting post for limiting the counterclockwise rotation of the rotating plate; both ends of the spring are connected with spring hooks, one of the spring hooks is hung in the hanging groove and the other spring hook is hung in the hanging hole. Under the action of the spring, the pushing component can achieve the effect of controlling the extension and retraction of the blade assembly.

[0013] Furthermore, the blade control mechanism also includes a pressing assembly, which includes a limiting shaft, a push plate, and a pressing plate. The limiting shaft is fixedly mounted on the inner solid plate. The push plate has a shaft hole and a strip hole. The push plate is movably sleeved on the limiting shaft through the shaft hole. A connecting post is fixedly mounted on the pressing plate. One end of the pressing plate is located outside the first handle, and the other end is connected to a connecting rod. The connecting post is slidably sleeved in the strip hole, and the connecting rod is connected to the first handle.

[0014] Furthermore, a first handle head is connected to the rear end of the first handle, and a second handle head is connected to the rear end of the second handle. The arrangement of the first handle head and the second handle head facilitates the surgeon's operation of the bipolar electrocoagulation separation forceps.

[0015] Furthermore, one end of the clamp head connecting wire extends to the outside of the second handle head. The clamp head connecting wire includes two electrode wires. One of the electrode wires is electrically connected to the first conductive plate at one end and connected to an electrical plug at the other end. The other electrode wire is electrically connected to the second conductive plate at one end and also connected to an electrical plug at the other end. The bipolar electrocoagulation separation clamp can be connected to a power source through the two electrical plugs so that high-frequency energy can be passed into the electrocoagulation clamp head through the clamp head connecting wire.

[0016] The beneficial effects of the present invention through the above technical solution are as follows:

[0017] 1. The first handle and the second handle of the present invention can control the opening and closing of the first clamp and the second clamp through the rotating component to achieve the purpose of clamping and electrocoagulating the tissue. Furthermore, the extension and retraction of the blade assembly can be controlled through the blade control mechanism to achieve the effect of cutting the electrocoagulated tissue. This bipolar electrocoagulation separation forceps has the functions of electrocoagulating and cutting and separating tissue. After electrocoagulating the tissue, the electrocoagulated tissue can be cut and separated. During use, the surgeon does not need to change to other surgical instruments to cut the electrocoagulated tissue. It is simple to operate, has a good tissue electrocoagulation effect, and high efficiency in cutting electrocoagulated tissue, thereby improving the efficiency of surgical operation.

[0018] 2. This invention uses two electrode wires to ensure that both the first and second conductive plates have electrodes. By rotating the assembly, the first and second clamps can open and close, achieving the purpose of clamping the tissue with the first and second clamps closed. This allows for electrocoagulation of the tissue between the first and second conductive plates, enabling hemostasis of the tissue in contact with the first and second conductive plates and forming electrocoagulated tissue to be cut. The stripes on the first and second conductive plates can increase the clamping force between the first and second clamps, improving the effect of tissue electrocoagulation.

[0019] 3. After electrocoagulation of the tissue, the present invention can control the blade assembly to cut and separate the electrocoagulated tissue through the blade control mechanism. The surgeon can rotate the movable handle and the rotating handle to drive the rotating plate to rotate. The rotating plate causes the push bar to push the strip blade to move in the direction of the electrocoagulation forceps head in the first slide groove and the second slide groove. The first slide groove and the second slide groove facilitate the movement of the strip blade, and the setting of the first guide groove and the second guide groove facilitates the movement of the blade head between the first forceps head and the second forceps head, so that the blade head can easily cut the electrocoagulated tissue.

[0020] 4. The spring in this invention allows the blade assembly to return to its initial position after cutting the electrocoagulated tissue by pushing the assembly, while the limiting post limits the rotating plate to prevent it from rotating counterclockwise. Attached Figure Description

Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0039] Example 1:

[0040] like Figures 1 to 13As shown, the bipolar electrocoagulation dissection forceps for open surgery includes a handle portion, the front end of which is connected to an electrocoagulation forceps head. The electrocoagulation forceps head includes a first forceps head 3 and a second forceps head 4 movably connected in a scissor-like manner. The handle portion includes a first handle 1 connected to the first forceps head 3 and a second handle 2 connected to the second forceps head 4. The first forceps head 3 and the second forceps head 4 are rotatably connected. The surgeon can control the opening and closing of the first forceps head 3 and the second forceps head 4 through the first handle 1 and the second handle 2. When the first handle 1 and the second handle 2 are far apart, the first forceps head 3 and the second forceps head 4 move apart; when the first handle 1 and the second handle 2 are close together, the first forceps head 3 and the second forceps head 4 move closer together. When the first clamp head 3 and the second clamp head 4 close, they can clamp and electrocoagulate the tissue. The first handle 1 is equipped with a blade control mechanism and a blade assembly. The blade control mechanism can control the blade assembly to perform telescopic movements to achieve the purpose of cutting and separating the electrocoagulated tissue. The blade control mechanism is connected to the blade assembly. One end of the blade assembly is located in the first handle 1 and the other end is located in the electrocoagulation clamp head. The second handle 2 is equipped with a clamp head connecting line 32 that is electrically connected to the first clamp head 3 and the second clamp head 4. High-frequency energy can be provided to the first clamp head 3 and the second clamp head 4 through the clamp head connecting line 32 to achieve electrocoagulation of human tissue.

[0041] The blade control mechanism includes an inner retaining plate 16, a cutting control assembly, a pushing assembly, and a spring 25 disposed above the inner retaining plate 16. The inner retaining plate 16 is fixedly disposed inside the first handle 1, wherein an insert post is installed inside the first handle 1, and an insert hole matching the insert post is opened on the inner retaining plate 16. The inner retaining plate 16 is installed inside the first handle 1 through the cooperation of the insert post and the insert hole. The cutting control assembly is connected to the pushing assembly, and the pushing assembly is connected to the blade assembly. One end of the spring 25 is connected to the pushing assembly, and the other end is connected to the inner retaining plate 16. After the first clamp head 3 and the second clamp head 4 clamp the tissue for electrocoagulation, the surgeon can cause the pushing assembly to move by using the cutting control assembly. The pushing assembly pushes the blade assembly to move between the first clamp head 3 and the second clamp head 4 to achieve the purpose of cutting the electrocoagulated tissue.

[0042] The first clamp head 3 includes a first clamp head plate 5 and a first clamp head block 6. The front end of the first clamp head plate 5 is connected to the first clamp head block 6, and the rear end is connected to the inner solid plate 16. A first conductive sheet 7 is provided on the inner surface of the first clamp head block 6. Both the first clamp head block 6 and the first conductive sheet 7 are arc-shaped structures. A plurality of spherical protrusions 9 are provided on the upper surface of the first conductive sheet 7, and a striped grid is also provided on the upper surface of the first conductive sheet 7. A first sliding groove 501 is opened on the inner surface of the first clamp head plate 5. A first guide groove 8 corresponding to the first sliding groove 501 is opened in the middle of the first clamp head block 6 and the first conductive sheet 7. In this embodiment, there are 5 spherical protrusions 9. The spherical protrusions 9 are made of conductive material and are fixed to the first conductive sheet 7. Because the concentration of charge on the spherical surface is greater than that on the plane, the electrocoagulation effect on the tissue is improved. The striped grid can increase the clamping force between the first clamp head 3 and the second clamp head 4 to prevent the first clamp head 3 and the second clamp head 4 from slipping when clamping the tissue, which would affect the electrocoagulation effect on the tissue.

[0043] The second clamp head 4 includes a second clamp head plate 10 and a second clamp head block 11. The front end of the second clamp head plate 10 is connected to the second clamp head block 11, and the rear end is connected to the second handle 2. A second conductive sheet 12 is provided on the inner surface of the second clamp head block 11. The second conductive sheet 12 is also provided with stripes. A second guide groove is also provided on the second clamp head block 11 and the second conductive sheet 12. The second guide groove corresponds to the first guide groove 8 vertically. Both the second guide groove and the first guide groove 8 have an arc-shaped structure. When this bipolar electrocoagulation separation clamp electrocoagulates human tissue, the clamp head connecting wire 32 enables the first conductive sheet 7 and the second conductive sheet 12 to have different electrodes. When the first clamp head 3 and the second clamp head 4 close to clamp the tissue, a closed circuit is formed between the first conductive sheet 7 and the second conductive sheet 12. The tissue located between the first conductive sheet 7 and the second conductive sheet 12 is electrocoagulated. The tissue in contact with the first conductive sheet 7 and the second conductive sheet 12 forms the electrocoagulated tissue that needs to be cut. In this embodiment, the first clamp head block 6 and the second clamp head block 11 are both made of insulating polytetrafluoroethylene.

[0044] The first pliers 3 is rotatably connected to the second pliers 4 via a rotating assembly 13. The rotating assembly 12 includes a rotating plate 15 and an arc-shaped column 14. A groove is provided on the upper surface of the second pliers plate 10, and an opening for the arc-shaped column 14 to pass through is provided in the groove. The rotating plate 15 is rotatably disposed in the groove. One end of the arc-shaped column 14 is connected to the first pliers plate 5, and the other end is fixedly connected to the rotating plate 15. The opening and closing effect of the first pliers 3 and the second pliers 4 can be achieved by rotating the assembly 13. There are two arc-shaped columns 14, which are symmetrically installed on both sides of the first sliding groove 501.

[0045] The inner retaining plate 16 has a second sliding groove 27 at its front end and a hanging groove 30 at its rear end. The second sliding groove 27 corresponds to the first sliding groove 501 on the first pliers plate 5. The first sliding groove 501 and the second sliding groove 27 facilitate the movement of the blade assembly and also limit the position of the blade assembly. A limiting groove is also formed in the second sliding groove 27. The width of the limiting groove matches the diameter of the push shaft 2601. The push shaft 2601 at the end where the push bar 26 is connected to the strip blade 28 is located in the limiting groove. Inside, the push shaft 2601 is slidably connected to the inner solid plate 16. The blade assembly is slidably disposed in the second slide groove 27. The blade assembly includes a strip blade 28. The front end of the strip blade 28 is connected to a cutting head 29, and the rear end is provided with an end hole 2801. The width of the front end of the strip blade 28 is smaller than the width of the rear end. The purpose is to facilitate the cutting head 29 to cut the electrocoagulated tissue. When the cutting head 29 moves in the first guide groove 8 to cut the electrocoagulated tissue, the front half of the strip blade 28 slides in the first guide groove 8 and is concealed in the first guide groove 8.

[0046] The cutting control assembly includes a rotating shaft 19 rotatably disposed within a first handle 1. One end of the rotating shaft 19 is connected to a rotating handle 17, and the other end is connected to a movable handle 18. Rotating shaft holes matching the rotating shaft 19 are provided on both sides of the first handle 1 and on the inner fixed plate 16. Both ends of the rotating shaft 19 pass through the rotating shaft holes and extend to the outside of the first handle 1. The rotating handle 17 and the movable handle 18 are located on the outer sides of the first handle 1. The rotating handle 17 is fixedly connected to the rotating shaft 19, and a sleeve matching the rotating shaft 19 is installed on the movable handle 18. The movable handle 18 is connected to the rotating shaft 19 through the sleeve. The pushing assembly includes a rotating plate 22 and a pushing bar 26. One end of the rotating plate 22 has a rotating shaft hole 2201, and the other end has... The rotating plate 22 is provided with a limiting hole 2202 and a hanging hole 2203. The rotating plate 22 is sleeved on the rotating shaft 19 through a rotating shaft hole 2201. A cutting opening is provided in the rotating shaft hole. A cutting part corresponding to the cutting opening is provided on the rotating shaft 19. Through the cooperation between the cutting opening and the cutting part of the rotating shaft 19, the rotating plate 22 can be driven to rotate when the rotating shaft 19 rotates. Both ends of the push bar 26 are provided with push shafts 2601. One push shaft 2601 is sleeved in the limiting hole 2202 and the other push shaft 2601 is sleeved in the end hole 2801. Both ends of the push bar 26 are movably connected to the rotating plate 22 and the strip blade 28 through the push shafts 2601. The push shafts 2601 are rotatably connected to the rotating plate 22 and the strip blade 28.

[0047] The inner plate 16 is also provided with a limiting post 20 for limiting the counterclockwise rotation of the rotating plate 22. The rotating plate 22 has an inner groove on one side. The limiting post 20 is located in the inner groove and is in contact with the rotating plate 22. The limiting post 20 is installed at the corner of the inner groove, and the lower part of the inner groove has a certain curvature so as to limit the position of the rotating plate 22 by the limiting post 20 and prevent the rotating plate 22 from rotating counterclockwise when it is in the prohibited state. Both ends of the spring 25 are connected to spring hooks 2501. One spring hook 2501 is hung in the hanging groove 30 and the other spring hook 2501 is hung in the hanging hole 2203. The hanging groove 30 has a "V" shaped structure. After the blade assembly cuts the electrocoagulated tissue, the spring 25 can drive the pushing assembly to return the blade assembly to the initial position.

[0048] The blade control mechanism also includes a pressing assembly, which includes a limiting shaft 21, a push plate 23, and a pressing plate 24. The limiting shaft 21 is fixedly mounted on the inner plate 16. The push plate 23 has a shaft hole 2301 and a strip hole 2302. The push plate 23 is movably sleeved on the limiting shaft 21 through the shaft hole 2301. A connecting post 2402 is fixedly mounted on the pressing plate 24. One end of the pressing plate 24 is located outside the first handle 1, and the other end is connected to a connecting rod 2401. The connecting rod 2401 is located inside the first handle 1 and has a certain elasticity. The connecting post 2402 is slidably sleeved in the strip hole 2302. The connecting rod 2401 is connected to the first handle 1. An opening is opened on the inner side of the first handle 1, and the pressing plate 24 is movably installed to the opening. When the first jaw 3 and the second jaw 4 are closed, the pressing plate 24 is in contact with the second handle 2.

[0049] The rear end of the first handle 1 is connected to a first handle head 101, and the rear end of the second handle 2 is connected to a second handle head 201. The first handle head 101 and the second handle head 201 facilitate the surgeon's operation of the bipolar electrocoagulation separation forceps.

[0050] One end of the pliers head connecting wire 32 extends to the outside of the second handle head 201. The pliers head connecting wire 32 includes two electrode wires. One of the electrode wires is electrically connected to the first conductive plate 7 at one end and connected to an electrical plug at the other end. The other electrode wire is electrically connected to the second conductive plate 12 at one end and also connected to an electrical plug at the other end. In actual use, the electrical plug is connected to the high-frequency electrosurgical unit, and the high-frequency energy is controlled by the foot switch connected to the high-frequency electrosurgical unit to be transmitted to the first conductive plate 7 and the second conductive plate 12 through the pliers head connecting wire. In this embodiment, the inner sides of the first pliers head plate 5 and the second pliers head plate 10 are provided with pre-embedded grooves for the electrode wires to pass through. The electrode wires are connected to the first conductive plate 7 and the second conductive plate 12 through the pre-embedded grooves.

[0051] The working principle of this invention is as follows: First, two electrical plugs are connected to the high-frequency electrosurgical unit. The surgeon, using the first handle head 101 and the second handle head 201, opens the first clamp head 3 and the second clamp head 4 away from each other under the action of the rotating component 13, and moves the electrocoagulation clamp head to the tissue to be electrocoagulated. Then, the rotating component 13 closes the first clamp head 3 and the second clamp head 4, clamping the tissue to be electrocoagulated. During the opening or closing of the first clamp head 3 and the second clamp head 4, the rotating plate 15 rotates within the groove on the second clamp head plate 10.

[0052] The surgeon then controls the high-frequency alternating current energy output via a foot switch. The high-frequency electrosurgical unit outputs high-frequency alternating current energy, which is transmitted to the first conductive plate 7 and the second conductive plate 12 through two electrode wires. Under the action of the electrode wires and the plug, the first conductive plate 7 and the second conductive plate 12 are respectively charged with positive and negative poles, so as to energize the tissue between the first conductive plate 7 and the second conductive plate 12, causing the tissue to produce an electrocoagulation effect, and the protein denatures and coagulates. During this process, when the first clamp 3 and the second clamp 4 clamp the tissue and the second handle 2 is in contact with the pressure plate 24, the second handle 2 presses against the pressure plate 24, and the pressure plate 24 moves inward to the first handle 1. The pressure plate 24 causes the push plate 23 to rotate around the limiting shaft 21. During the rotation of the push plate 23, it pushes the rotating plate 22 to rotate, and the rotating plate 22 pushes the push bar 26 to move. The push bar 26 pushes the blade assembly forward. During this process, the blade assembly does not cut the electrocoagulated tissue.

[0053] After the tissue electrocoagulation is completed, the movable handle 18 and the rotating handle 17 are rotated clockwise. The movable handle 18 and the rotating handle 17 drive the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating plate 22 to rotate clockwise. The rotating plate 22 stretches the spring 25 and pushes the push bar 26 to move. The push bar 26 pushes the strip blade 28 to move into the first guide groove 8 and the second guide groove within the first slide groove 501 and the second slide groove 27. The push shaft 2601, which is connected to the strip blade 28 at one end, moves within the limiting slide groove. When the blade head 29 moves into the first guide groove 8 and the second guide groove, the forward movement of the blade head 29 cuts off the electrocoagulated tissue. After the electrocoagulated tissue is cut, release the movable handle 18 and the rotating handle 17. The spring 25 pulls the rotating plate 22 back to its original position, which in turn pulls the push bar 26 back to its original position. This causes the push bar 26 to pull the strip blade 28 backward, moving the blade head 29 out of the first guide groove 8 and the second guide groove. The strip blade 28 and the blade head 29 then return to their original positions. This completes the electrocoagulation and cutting of the human tissue.

[0054] Example 2:

[0055] like Figures 14-15As shown, the similarities between Embodiment 2 and Embodiment 1 will not be described in detail. The difference is that the blade control mechanism in Embodiment 2 does not include the pressing component and the spring 25, and the cutting control component does not include the rotating handle 17 and the movable handle 18. The first handle head 101 is rotatably connected to the first handle 1 through the rotating shaft 19, and the first handle head 101 is fixedly connected to the rotating shaft 19. A compression spring is provided between the first handle head 101 and the second handle head 201. One end of the compression spring is connected to the first handle head 101, and the other end is connected to the second handle head 201.

[0056] When the first clamp head 3 and the second clamp head 4 are open, the compression spring is in a stretched state; after the first clamp head 3 and the second clamp head 4 close and clamp the tissue, the surgeon can control the high-frequency alternating current energy output through the foot switch. The high-frequency electrosurgical unit outputs high-frequency alternating current energy and supplies it to the first conductive plate 7 and the second conductive plate 12 through the two electrode wires to electrocoagulate the tissue between the first conductive plate 7 and the second conductive plate 12.

[0057] Then, the first handle head 101 is rotated to rotate towards the second handle head 201. During the rotation of the first handle head 101, the compression spring is compressed, and the first handle head 101 drives the rotating plate 22 to rotate counterclockwise. The rotating plate 22 drives the push bar 26 to move, and the push bar 26 pushes the strip blade 28 forward in the first slide groove 501 and the second slide groove. Under the action of the rotating plate 22 and the push bar 26, the cutter head 29 moves into the first guide groove 8 and the second guide groove to cut the electrocoagulated tissue. After the electrocoagulated tissue is cut, the first handle head 101 is released. Under the force of the compression spring, the first handle head 101 returns to its original position, so that the rotating plate 22, the push bar 26 and the blade assembly return to their original positions.

[0058] The embodiments described above are merely preferred embodiments of the invention and are not intended to limit the scope of the invention. Therefore, any equivalent changes or modifications made to the technical solutions described in the claims of this invention should be included within the scope of the patent application of this invention.
