Description

Technical Field

[0001] This application relates to the technical field of medical electrosurgical devices, and in particular to an adjustable smokeless LEEP knife. Background Technology

[0002] The LEEP (Loop Electrosurgical Excision Procedure) is a high-frequency electrosurgical unit primarily used for minimally invasive diagnosis and treatment of cervical diseases. LEEP employs directional radiofrequency wave emission technology. Within the tissue at the emitter electrode, a radiofrequency energy directly excites the liquid polar molecules within the tissue, causing plasma oscillations and breaking molecular bonds. This achieves precise and minimally invasive cutting at low temperatures (40℃~70℃), and is often used for hemostasis, tissue ablation, and shrinkage. However, LEEP generates smoke during the procedure, which obstructs the surgeon's view and affects the surgical process. Therefore, a smoking tube needs to be placed in the surgical area for continuous smoking during the procedure. Because gynecological surgeries are performed through the vagina, the surgical area is small, and placing a smoking tube can affect the surgeon's operating space, field of vision, and even surgical efficiency.

[0003] Chinese patent CN204169922U discloses an adjustable smokeless liposuction knife, comprising a blade head, a hollow blade rod, and a handle. The handle has a hollowed-out cavity. A first air intake is located at the blade head. One end of the hollow blade rod is connected to the blade head, and the other end is connected to the handle. A second air intake is located at the end of the handle away from the hollow blade rod, and this second air intake is connected to an external suction device. An airflow adjustment device is located inside the hollow handle, and an adjustment button linked to this device is located on the outer wall of the hollow handle. A linkage is provided between the airflow adjustment device and the adjustment button. The suction device effectively draws out exhaust gas from the hollow space between the blade rod and the handle. The airflow adjustment device, located within the suction channel, allows for adjustment of the suction volume.

[0004] The aforementioned technologies have the following drawbacks: Since bleeding may still occur during the procedure, although the suction device can remove the smoke generated when the blade is energized and in contact with the tissue, it will also remove any blood seeping from below the blade. Due to the obstruction of the blade's view, the surgeon may not be able to detect the bleeding immediately, which may affect the surgeon's judgment. Utility Model Content

[0005] In order to improve the problem that the suction device may draw out blood while smoking, which may not be easily noticed by the surgeon and may lead to surgical risks, this application provides an adjustable smokeless LEEP knife.

[0006] The adjustable smokeless LEEP knife provided in this application adopts the following technical solution:

[0007] An adjustable smokeless liposuction knife includes a blade head, a hollow blade rod, and a handle. The blade head has an air inlet communicating with the hollow portion of the hollow blade rod. The handle has an air outlet communicating with the hollow portion of the hollow blade rod. A transparent flexible tube located inside the handle is connected to the end of the hollow blade rod away from the blade head. The end of the transparent flexible tube away from the blade head communicates with the air outlet. The handle has a viewing window for displaying the transparent flexible tube and an adjustment component for squeezing the transparent flexible tube.

[0008] Furthermore, the handle has a receiving groove for accommodating the transparent flexible tube, and the adjustment assembly includes a control rod hinged to the wall of the receiving groove. One end of the control rod near the transparent flexible tube is fixed to a pressure plate orthogonal to the axial direction of the transparent flexible tube, and the other end extends to the outside of the handle.

[0009] Furthermore, the handle has a groove on the bottom wall of the receiving groove that is adapted to the gap between the pressure plate and the handle. When the control rod is flipped so that the pressure plate presses against the transparent hose, the pressure plate and the flattened transparent hose are embedded in the groove.

[0010] Furthermore, a paddle is fixed to one end of the control lever that protrudes from the handle and extends toward the blade head. The paddle and the pressure plate are located on the side of the hinge between the control lever and the handle, near the blade head.

[0011] Furthermore, the transparent hose is also provided with an anti-flow structure to prevent the liquid in the transparent hose from flowing towards the blade.

[0012] Furthermore, the anti-drainage structure includes a connecting cylinder installed on the transparent flexible tube, and a conical sleeve with its tip facing away from the blade is fixed to the inner wall of the connecting cylinder, and the tip of the conical sleeve has a through hole.

[0013] Furthermore, the tip of the conical sleeve is fixedly connected to an extension tube coaxial with the connecting cylinder at the perforation.

[0014] In summary, the beneficial technical effects of this application are as follows:

[0015] During the procedure, the air outlet is connected to an external negative pressure device. Using a transparent tube, a hollow blade, and an air inlet located at the blade tip, fumes from the surgical site are drawn in. By adjusting the transparent tube using an adjustable component, the flow rate of the fumes within it can be changed, thereby altering the suction force at the air inlet. This allows for controlled fume extraction during surgery. Furthermore, if bleeding occurs at the surgical site, the surgeon can observe the bleeding within the transparent tube through a viewing window on the handle, enabling timely prediction and improving the quality of the procedure while reducing risks.

[0019] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application discloses an adjustable smokeless LEEP knife. (Refer to...) Figure 1 An adjustable smokeless liposuction knife includes a blade head 11, a hollow blade rod 12, and a handle 13. The blade head 11 has an air inlet 14 communicating with the hollow portion of the hollow blade rod 12. The handle 13 has an air outlet 15 communicating with the hollow portion of the hollow blade rod 12, and the air outlet 15 is used to connect to an external negative pressure device. A transparent flexible tube 2 located inside the handle 13 is connected to the end of the hollow blade rod 12 away from the blade head 11. The end of the transparent flexible tube 2 away from the blade head 11 communicates with the air outlet 15. The handle 13 has a viewing window 16 for displaying the transparent flexible tube 2, and an adjustment component for squeezing the transparent flexible tube 2 is provided on the handle 13.

[0021] With this setup, during the surgeon's operation, the air outlet 15 is connected to an external negative pressure device. The transparent flexible tube 2, the hollow blade 12, and the air inlet 14 located on the blade head 11 can be used to draw in fumes from the surgical site. Furthermore, by adjusting the components to compress the transparent flexible tube 2, the flow rate of fumes within it can be changed, thereby altering the suction force of the air inlet 14. This allows for adjustable fume extraction during surgery. Additionally, when bleeding occurs at the surgical site, the surgeon can observe the bleeding within the transparent flexible tube 2 through the viewing window 16 on the handle 13, enabling timely prediction and thus improving the quality of the procedure and reducing surgical risks.

[0022] On the other hand, the handle 13 has a receiving groove 17 for accommodating the transparent flexible tube 2. The adjustment assembly includes a control rod 31 hinged to the wall of the receiving groove 17. One end of the control rod 31 near the transparent flexible tube 2 is fixedly connected to a pressure plate 32 orthogonal to the axial direction of the transparent flexible tube 2, and the other end extends out of the handle 13. Furthermore, the end of the control rod 31 protruding out of the handle 13 is fixedly connected to a paddle 33 extending towards the blade head 11. The paddle 33 and the pressure plate 32 are located on the side of the hinge between the control rod 31 and the handle 13 near the blade head 11.

[0023] With this setup, when the operator holds the handle 13, they can press the paddle 33 with their fingertips to make the paddle 33 drive the control lever 31 to rotate on the handle 13 toward the bottom wall of the receiving groove 17, so that the pressure plate 32 on the control lever 31 can squeeze the transparent tube 2, and the adjustable smoking effect of the LEEP knife of this application can be achieved with just one hand.

[0024] Meanwhile, the handle 13 has a groove 171 on the bottom wall of the receiving groove 17 that is adapted to the gap of the pressure plate 32. When the control rod 31 is flipped to the point where the pressure plate 32 presses against the transparent hose 2, the pressure plate 32 and the flattened transparent hose 2 are embedded in the groove 171.

[0025] With this setup, when the pressure plate 32 squeezes the transparent hose 2 into the groove 171, the transparent hose 2 is bent and pressed tightly in the groove 171, which can completely cut off the transparent hose 2, so that the practitioner can easily and completely turn off the smoking function of this application without having to operate the external negative pressure device.

[0026] Meanwhile, considering that after the external negative pressure equipment is turned off, some residual liquid in the transparent hose 2 may flow back to the blade head 11 along the transparent hose 2 and the hollow blade rod 12, which may cause secondary contamination to the wound, the transparent hose 2 is also equipped with an anti-flow structure to prevent the liquid in the transparent hose 2 from flowing towards the blade head 11. The anti-flow structure includes a connecting cylinder 41 installed on the transparent hose 2. The connecting cylinder 41 is coaxial with the transparent hose 2, and the connecting cylinder 41 is also made of transparent plastic. A conical sleeve 42 with its tip pointing away from the blade head 11 is fixed to the inner wall of the connecting cylinder 41, and the tip of the conical sleeve 42 has a through hole 43.

[0027] With this configuration, even if the external negative pressure equipment is turned off and the liquid in the transparent hose 2 flows back, this part of the liquid will first flow back into the connecting cylinder 41 for storage. The perforation 43 on the cone sleeve 42 can ensure the effective positive smoke extraction effect of the negative pressure equipment on the one hand; on the other hand, it can effectively prevent the guided liquid from passing through the cone sleeve 42 and flowing back into the hollow cutter bar 12 and the cutter head 11, thus effectively achieving the anti-flow effect.

[0028] Furthermore, the tip of the cone sleeve 42 is fixed to the through hole 43 with an extension tube 44 coaxial with the connecting cylinder 41, thereby increasing the liquid carrying capacity in the connecting cylinder 41. At the same time, the smaller opening of the extension tube 44 can further enhance the prevention of liquid backflow.

[0029] The implementation principle of an adjustable smokeless LEEP knife in this application embodiment is as follows:

[0030] During the procedure, the air outlet 15 is connected to an external negative pressure device. Using the transparent flexible tube 2, the hollow blade 12, and the air inlet 14 located on the blade head 11, fumes from the surgical site are drawn in. By pressing the lever, the pressure plate 32 on the control rod 31 is squeezed, altering the flow rate of fumes within the transparent flexible tube 2 and consequently changing the suction force of the air inlet 14. This allows for adjustable fume extraction during surgery. Furthermore, when bleeding occurs at the surgical site, the surgeon can observe the bleeding within the transparent flexible tube 2 through the viewing window 16 on the handle 13, enabling timely prediction and improving the quality of the procedure while reducing risks.
