Description

Technical Field

[0001] This utility model relates to the field of electrosurgical instruments, specifically to an electrosurgical knife equipped with a light source. Background Technology

[0002] Existing traditional electrosurgical units produce smoke due to the thermal effect during use. The smoke contains harmful gases, which not only have a certain impact on the health of the surgeon, but also obstruct the surgical field of vision, making it difficult for the surgeon to operate. Insufficient illumination from the surgical light source can also cause visual obstruction, limiting the surgeon's operation and making it difficult to operate the electrosurgical unit for precise cutting.

[0003] Although existing technologies use surgical lights to supplement illumination and reduce visual obstruction, traditional surgical lights are still bulky and inflexible in terms of light distribution during surgery, and cannot illuminate deep tissues, thus still causing blind spots.

[0004] Furthermore, surgeons cannot adjust the light source at any time, and need to free up their hands to operate, which is very time-consuming and not conducive to improving surgical efficiency. The surgeon may also unconsciously block the light source due to body movement or changes in posture, which will further obstruct the surgical field of vision and make the operation more difficult, thereby increasing the surgical risk and the risk of postoperative complications for the patient. Utility Model Content

[0005] The purpose of this invention is to provide an electrosurgical unit with a light source, so as to solve the technical problem that the light source is easily blocked and the field of vision is obstructed when the electrosurgical unit is operated.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] An electric knife equipped with a light source includes a handle, a lamp tube arranged parallel to the handle, a lamp head at one end of the lamp tube, a push rod at the lamp head, the push rod being mounted inside the lamp tube via a shaft, and one end of the shaft penetrating the outer wall of the lamp tube and having an adjustment knob.

[0008] The handle is provided with a blade at one end near the lamp head, and the lamp head swings around the horizontal center line extension of the blade to form an angle adjustment structure.

[0009] As a preferred embodiment of this utility model, the handle and the lamp tube are an integral structure, and a button is provided on one side of the handle, with the plane of the button being perpendicular to the plane of the adjustment knob.

[0010] As a preferred embodiment of this utility model, the push rod includes a short rod and a long rod, the long rod and the short rod are hinged together by a pivot to form an L-shaped structure, and one end of the long rod is hinged to the lamp head by a pivot.

[0011] In a preferred embodiment of this utility model, the shaft swings back and forth around its connection with the lamp tube, causing the short rod to rotate synchronously, and the long rod translates along the length of the lamp tube, pushing the lamp head to swing around its connection with the lamp tube for angle adjustment.

[0012] As a preferred embodiment of this utility model, the outer wall of the shaft is provided with a driving gear, and a driven gear that meshes with the driving gear is provided inside the lamp tube.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This utility model adopts an integrated form to construct an electrosurgical structure with an adjustable light source. By setting a light group on the handle to supplement the light source in the direction of the blade head, the aim is to reduce visual obstruction. Moreover, the integrated design allows the operator to coordinate operation with one hand, reducing the burden and inconvenience of the operator. The adjustment is more precise by swinging, and the purpose of precise supplemental lighting is achieved by adjusting the angle of the light source, thereby improving the operation efficiency and reducing the surgical risk.

[0024] 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.

[0025] like Figure 1 and Figure 2 As shown, this utility model provides an electric knife with a light source, including a handle 10, a lamp tube 20 arranged parallel to the handle 10, a lamp head 21 arranged at one end of the lamp tube 20, a push rod 22 arranged on the lamp head 21, the push rod 22 is installed in the lamp tube 20 through a shaft 23, one end of the shaft 23 passes through the outer wall of the lamp tube 20 and is provided with an adjustment knob 24;

[0026] A blade 11 is provided at one end of the handle 10 near the lamp head 21. The lamp head 21 swings around the horizontal center line extension of the blade 11 to form an angle adjustment structure.

[0027] This utility model adopts an integrated form to construct an electrosurgical structure with an adjustable light source. By setting a light group on the handle to supplement the light source in the direction of the blade head, the aim is to reduce visual obstruction. Moreover, the integrated design allows the operator to coordinate operation with one hand, reducing the burden and inconvenience of the operator. The adjustment is more precise by swinging, and the purpose of precise supplemental lighting is achieved by adjusting the angle of the light source, thereby improving the operation efficiency and reducing the surgical risk.

[0028] The lamp tube 20 installed on the handle 10 provides space for the installation and movement of the lamp head 21. When operating by hand, the lamp head 21 can be used to install a bulb to provide supplemental lighting to the processing position of the blade head 11. The lamp tube 20 is parallel to the handle 10, which reduces the obstruction of the light source when operating by hand. Furthermore, the direction of the light emission from the lamp head 21 is consistent with the direction of the blade head 11, which reduces the obstruction of the light source by the blade head 11 and the occurrence of shadows or other visual obstacles.

[0029] like Figure 1 and Figure 2As shown, the handle 10 and the lamp tube 20 are integrated into one piece, and a button 12 is provided on one side of the handle 10. The plane of the button 12 is perpendicular to the plane of the adjustment knob 24.

[0030] By combining the handle 10 and the lamp tube 20, an integrated structure is formed, realizing the integration of lighting and cutting functions, simplifying the use of surgical tools. The adjustment knob 24 can be operated while holding the handle 10 to operate the button 12. The purpose of single-handed operation is achieved through the coordination of different fingers, which can reduce the burden on medical staff who need to coordinate with other light source devices during operation, and reduce the situation where other light source devices may cause obstruction or make single-handed operation impossible.

[0031] It helps reduce the time spent adjusting the lighting during surgery and improves surgical efficiency. The 24-roll adjustment knob takes into account the surgeon's grip comfort and is less likely to cause hand fatigue.

[0032] By positioning the button 12 and the adjustment knob 24 on different sides of the handle 10, it is convenient to operate the handle with one hand by using other fingers to move the adjustment knob 24. This allows for single-handed operation and also enables the integration of the light source and the electrosurgical unit, reducing interference from lighting equipment during surgery and improving surgical safety.

[0033] like Figure 2 and Figure 3 As shown, the push rod 22 includes a short rod 221 and a long rod 222. The long rod 222 and the short rod 221 are hinged together by a pivot to form an L-shaped structure. One end of the long rod 222 is hinged to the lamp head 21 by a pivot.

[0034] The L-shaped push rod 22 can drive the short rod 221 to rotate when the shaft 23 rotates, further pushing the long rod 222 to one end, thereby causing the lamp head 21 to swing. The lamp head 21, the long rod 222 and the push rod 22 are all hinged by a pivot, which makes it less likely to jam when the shaft 23 rotates.

[0035] An LED pen-shaped bulb is installed on the lamp holder 21, and the lamp holder 21 is a waterproof lamp holder adapted for the LED pen-shaped bulb, which has good waterproof performance and is suitable for use in medical environments.

[0036] like Figure 2 and Figure 3 As shown, the shaft 23 swings back and forth around its connection with the lamp tube 20, causing the short rod 221 to rotate synchronously, and the long rod 222 moves along the length of the lamp tube 20, pushing the lamp head 21 to swing around its connection with the lamp tube 20 to adjust the angle.

[0037] The lamp head 21 is hinged to one end of the lamp tube 20 via a rotating shaft. By rotating the adjustment knob 24, the shaft 23 and the short rod 221 rotate synchronously. The tilting of the short rod 221 during rotation pushes the long rod 222 to move, which in turn pushes a point on the lamp head 21 to move, thereby tilting the lamp head 21 to adjust the angle of the emitted light source. This allows medical staff to adjust the light source angle according to actual operational needs during operation, thereby reducing visual obstruction and facilitating surgery. It is also suitable for adjusting the angle for different surgical sites to meet different operational needs and improve the safety of the operation.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, a drive gear 231 is provided on the outer wall of the shaft 23, and a driven gear 232 that meshes with the drive gear 231 is provided inside the lamp tube 20.

[0039] The meshing connection between the driving gear 231 and the driven gear 232 helps to reduce the change in the angle of the lamp head 21 caused by shaking when operating the handle 10;

[0040] During adjustment, rotating the shaft 23 drives the active gear 231 to rotate synchronously, while simultaneously engaging the driven gear 232 to rotate. This improves the stability of the shaft 23 when operating without external force and allows the operator to better feel the adjustment range of the lamp head 21. This enables medical staff to adjust and use the lamp more precisely, allowing the precise light source to assist the electrosurgical unit in achieving better hemostasis and reducing bleeding.

[0041] Precise adjustment of the light source facilitates accurate cutting, thereby reducing the smoke generated during electrosurgical operation and minimizing its impact on the operating room environment and personnel.

[0042] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
