Description

Technical Field

[0001] This utility model relates to the field of high-frequency surgical electrode technology, specifically a disposable high-frequency surgical electrode. Background Technology

[0002] A high-frequency surgical electrode knife is an electrosurgical instrument used in conjunction with a high-frequency surgical device to cut and coagulate tissue. The high-frequency generator inside the high-frequency electrosurgical knife generates a high-frequency, high-voltage current, which is transmitted to the surgical site on the patient's body through the connected surgical electrode. Because the contact area between the surgical electrode tip and the biological tissue is very small, the current density is very high, generating heat in the tissue, causing the cells to expand, burst, and vaporize, thereby achieving the cutting effect.

[0003] Compared to traditional mechanical scalpels, electrosurgical units can complete tissue cutting and hemostasis more quickly, reducing the risk to patients during surgery. Doctors can easily control the start, stop, and power adjustment of the electrosurgical unit using hand or foot switches, making the operation relatively simple. However, existing high-frequency surgical electrodes have an excessively large area covered by the doctor's hand during operation. This can easily lead to accidental activation of operation buttons when the electrode encounters resistance while cutting muscle tissue, reducing the safety of using high-frequency surgical electrodes.

[0004] Therefore, it is necessary to redesign the high-frequency surgical electrode to effectively prevent the problem that the doctor's hand covering too large an area of ​​the electrode during operation may accidentally touch the operation button when the electrode encounters resistance while cutting muscle tissue, leading to safety accidents. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a disposable high-frequency surgical electrode knife with the advantage of good protection. It solves the problem that during the operation of the high-frequency surgical electrode knife, the doctor's hand holding the electrode knife covers too large an area, which can easily lead to accidental touch of the operation button when the electrode knife encounters resistance while cutting muscle tissue, causing the palm to slide on the surface of the electrode knife.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a disposable high-frequency surgical electrode knife, comprising; The housing has a threaded sleeve fixedly connected to the left side of its inner wall. The inner cavity of the threaded sleeve is movably connected to a cutting head via a thread. The left side of the cutting head extends through to the left side of the housing.

A moving mechanism is horizontally fixedly connected to the bottom of the inner cavity of the connecting box. The moving mechanism includes a crossbar, a sleeve rod, a support, a plate, a connecting rod, a hollow cylinder, a rotating rod, a turntable, and a double-headed retaining ring. A crossbar is horizontally fixed to the bottom of the inner cavity of the connecting box. A sleeve rod is slidably sleeved on the left side of the crossbar surface. A support is fixedly connected to the top of the sleeve rod. A plate is fixedly connected to the top of the right side of the inner wall of the connecting box. The left side of the plate passes through the left side of the support and is fixedly connected to the left side of the inner wall of the connecting box. A connecting rod is fixedly connected to the back end of the support. The back end of the connecting rod is slidably connected to the back end of the inner wall of the connecting box. A hollow cylinder is fixedly connected to the front end of the support. A rotating rod is movably connected to the right side of the inner wall of the connecting box via a bearing seat. A turntable is fixedly connected to the right side of the rotating rod. A double-headed retaining ring is fixedly connected to the left side of the rotating rod, penetrating into the interior of the connecting box. A protective component is fixedly connected to the top of the connecting rod, penetrating the top of the connecting box.

[0007] As a preferred embodiment of this utility model, the protective component includes a contact plate and an acrylic plate. The top of the connecting rod is fixedly connected to the contact plate through the top of the connecting box. An acrylic plate is fixedly connected to the left side of the contact plate. The bottom of the acrylic plate contacts the top of the housing. The acrylic plate is located on top of the electric cutting button.

[0008] As a preferred embodiment of this utility model, anti-slip blocks are fixedly connected to the left and right sides of the top of the acrylic sheet.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 5 As shown, the present invention provides a disposable high-frequency surgical electrode knife, comprising: The housing 1 has a threaded sleeve 2 fixedly connected to the left side of the inner wall of the housing 1. The inner cavity of the threaded sleeve 2 is connected to the cutter head 3 by a thread. The left side of the cutter head 3 extends through to the left side of the housing 1. The top of the housing 1 is provided with an electric cutting button 4. The front and back ends of the housing 1 are both fixedly connected with a connecting box 5. The bottom of the inner cavity of the connecting box 5 is horizontally fixedly connected with a moving mechanism 6. The moving mechanism 6 includes a crossbar 61, a sleeve rod 62, a support 63, a plate 64, a connecting rod 65, a hollow cylinder 66, a rotating rod 67, a turntable 68, and a double-headed retaining ring 69. The crossbar 61 is horizontally fixedly connected to the bottom of the inner cavity of the connecting box 5. The sleeve rod 62 is slidably sleeved on the left side of the surface of the crossbar 61. The support 63 is fixedly connected to the top of the sleeve rod 62. The plate 64 is fixedly connected to the top of the right side of the inner wall of the connecting box 5. The left side of the plate 64 passes through the left side of the support 63 and connects with the left side of the inner wall of the connecting box 5. The support 63 is fixedly connected to the back end of the support 63. The back end of the connecting rod 65 is slidably connected to the back end of the inner wall of the connecting box 5. The front end of the support 63 is fixedly connected to the hollow cylinder 66. The right side of the inner wall of the connecting box 5 is movably connected to the rotating rod 67 through the bearing seat. The right side of the rotating rod 67 is fixedly connected to the turntable 68. The left side of the rotating rod 67 extends through the interior of the connecting box 5 and is fixedly connected to the double-headed retaining ring 69. The top of the connecting rod 65 extends through the top of the connecting box 5 and is fixedly connected to the protective component 7.

[0017] refer to Figure 3 The protective component 7 includes a contact plate 71 and an acrylic plate 72. The top of the connecting rod 65 passes through the top of the connecting box 5 and is fixedly connected to the contact plate 71. The left side of the contact plate 71 is fixedly connected to the acrylic plate 72. The bottom of the acrylic plate 72 contacts the top of the housing 1. The acrylic plate 72 is located on top of the electric cutting button 4.

[0018] As a technical optimization of this utility model, by setting the protective component 7, the contact plate 71 can drive the acrylic plate 72 to cover the surface of the electric cutting button 4 for shielding and protection.

[0019] refer to Figure 3 Anti-slip blocks 8 are fixedly connected to the left and right sides of the top of the acrylic sheet 72. There are several anti-slip blocks 8, which are evenly distributed. The anti-slip blocks 8 are used in conjunction with the acrylic sheet 72.

[0020] As a technical optimization of this utility model, the anti-slip block 8 can assist the acrylic plate 72 in its work, while increasing frictional resistance and preventing the smooth surface of the acrylic plate 72 from having no force points that would affect operation.

[0021] refer to Figure 5 A groove 9 is provided on the inner side of the support 63 and at the position corresponding to the plate 64. The groove 9 is used in conjunction with the plate 64.

[0022] As a technical optimization of this utility model, the groove 9 can assist the plate 64 in its work and also serve as a limit, preventing the support 63 from tilting during movement.

[0023] refer to Figure 5The hollow cylinder 66 has an inner cavity with a receiving groove 10, which is used in conjunction with the double-headed retaining ring 69.

[0024] As a technical optimization of this utility model, by setting the receiving groove 10, the double-headed retaining ring 69 can pass completely through the receiving groove 10, avoiding the phenomenon that the double-headed retaining ring 69 will get stuck inside the hollow cylinder 66 due to the small diameter of the receiving groove 10.

[0025] refer to Figure 4 A spring 11 is sleeved on the surface of the crossbar 61. The left and right sides of the spring 11 are fixedly connected to the right side of the sleeve 62 and the surface of the crossbar 61, respectively.

[0026] As a technical optimization of this utility model, the spring 11 can assist the sleeve rod 62 in working and at the same time play a role in reset and buffering, so as to prevent the sleeve rod 62 from failing to reset after moving, which would cause the machine to stop working continuously.

[0027] The working principle and usage process of this utility model are as follows: When in use, hold the housing 1 and the cutter head 3. Align the threaded end of the cutter head 3 with the center of the threaded sleeve 2, then rotate the cutter head 3 clockwise to screw it into the threaded sleeve 2 to complete assembly. Similarly, rotate the cutter head 3 counterclockwise to disassemble it from the threaded sleeve 2. The disassembled cutter head 3 is disposable. When using it again, take a new cutter head 3 and reassemble it according to the above operation. After assembly, manually push the acrylic plate 72 to the right. The movement of the acrylic plate 72 to the right causes the contact plate 71 and the connecting rod 65 to move synchronously. The movement of the acrylic plate 72 exposes the electric cutting button 4, while the connecting rod 65 moves... The movement of the support 63 causes it to move, and the support 63 moves stably on the surface of the plate 64 in conjunction with the groove 9. The movement of the support 63 to the right causes the sleeve rod 62 to move along the surface of the crossbar 61. During the movement of the sleeve rod 62, the spring 11 is compressed. At the same time, the hollow cylinder 66 also moves to the right with the support 63. When the hollow cylinder 66 moves to the double-headed retaining ring 69, it engages with the receiving groove 10 to allow it to pass through and protrude on the left side. Then, the turntable 68 is manually rotated 90 degrees clockwise. The rotation of the turntable 68 causes the rotating rod 67 and the double-headed retaining ring 69 to rotate as well. The rotation of the double-headed retaining ring 69 changes its angle so that it can no longer pass through the receiving groove 10. The rotated double-headed retaining ring 69 locks the hollow cylinder 66 in place. The fixed position of the hollow cylinder 66 fixes the positions of the support 63 and connecting rod 65. The fixed position of the connecting rod 65 fixes the positions of the contact plate 71 and acrylic plate 72. The fixed position of the acrylic plate 72 prevents it from covering the electrosurgical cutting button 4. At this time, the operator presses the electrosurgical cutting button 4, causing the high-frequency generator inside the housing 1 to generate a high-frequency, high-voltage current. This current is transmitted to the surgical site on the patient's body through the connected cutting head 3. Because the contact area between the cutting head 3 and the biological tissue is very small, the current density is very high, generating heat in the tissue, causing the cells to expand, burst, and vaporize, thereby achieving the cutting... Before surgery, the turntable 68 is rotated 90 degrees counterclockwise. The rotation of the turntable 68 causes the rotating rod 67 and the double-headed retaining ring 69 to rotate and reset to their initial angle. The double-headed retaining ring 69 can release the fixation of the hollow cylinder 66 through the receiving groove 10. Under the reset of the spring 11, the sleeve rod 62 and the support 63 are pushed to the left to reset. The left reset of the support 63 causes the connecting rod 65 and the contact plate 71 to move accordingly. The left reset of the contact plate 71 causes the acrylic plate 72 to cover the surface of the electric cutting button 4 again, so that even if the operator slips while holding the housing 1 during surgery, he cannot contact the electric cutting button 4, thus achieving the function of safe use.

[0028] In summary, this disposable high-frequency surgical electrode knife, through the coordinated use of the housing 1, threaded sleeve 2, blade 3, electrocautery button 4, connecting box 5, moving mechanism 6, crossbar 61, sleeve rod 62, support 63, flat plate 64, connecting rod 65, hollow cylinder 66, rotating rod 67, turntable 68, double-headed retaining ring 69, and protective component 7, solves the problem of existing high-frequency surgical electrode knives where the doctor's hand covering the electrode knife is too large during operation, making it easy for the palm to slide on the electrode knife surface and accidentally touch the operation button when the electrode knife encounters resistance while cutting muscle tissue, leading to safety accidents.
