[0027] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 8 As shown, this utility model provides a preferred embodiment of a scalpel device with an illumination function.

[0029] A surgical scalpel device with illumination function includes a main body, a blade 100, and an illumination lamp 600. The main body includes a blade portion 200, an extension portion 300, and a handle 400. The main body also includes a through channel 101 that sequentially passes through the blade portion 200, the extension portion 300, and the handle 400. The blade portion 200 includes a connecting section 120 and a blade section 110. The connecting section 120 is connected to the end of the extension portion 300. The opening of the through channel 101 is formed on the front end face of the connecting section 120. The blade section 110... The rear end face of the blade 100 is disposed on the front end face of the connecting section 120 and covers part of the opening of the through channel 101; the blade 100 is fixed to the front end face of the blade section 110; the external guide rod can be inserted from the end of the handle 400 into the through channel 101 until it reaches the opening of the through channel 101 and abuts against the end face of the blade section 110; the mounting cavity 102 of the lighting lamp 600 is connected to the through channel 101, and the light emitted by the lighting lamp 600 illuminates along the through channel 101 and exits from the opening of the through channel 101.

[0030] Specifically, the handle 400 is a grip structure. By gripping the handle 400, the extension 300 is inserted deep into the body, thereby controlling the blade 200 to approach the flesh, and then cutting is performed through the blade 100. The handle 400 is ergonomic, allowing the doctor to comfortably grip and precisely control the movement of the blade 100. Through the operation of the handle 400, the doctor can adjust the position and angle of the blade 200 to ensure the accuracy and safety of the cutting.

[0031] Furthermore, the main body also incorporates a conductive wire connected to the blade 100. The conductive wire extends from the end of the handle 400 and is fitted with a plug 520, which connects to a high-frequency energy generator. Regarding the principle of high-frequency cutting, the blade 100 is made of conductive material and generates a high-frequency current through a high-frequency power supply. This high-frequency current typically ranges from tens to hundreds of kilohertz. When the high-frequency current passes through the blade 100 and enters human tissue, it encounters the resistance of the tissue, causing energy release and heat generation. This heat denatures the proteins in the human tissue, thereby achieving the purpose of cutting the tissue.

[0032] In this embodiment, the front end face of the cutting edge segment 110 is provided with a mounting groove 211. The cutting edge segment 110 and the connecting segment 120 are arranged perpendicularly, and the connecting segment 120 is disposed in the mounting groove 211. The mounting groove 211 is mainly provided for mounting and fixing the cutting edge 100 and for connecting the cutting edge 100 to the conductive wire. Positioning the blade at the foremost point of the cutting edge portion 200 facilitates cutting at the end of the cutting edge 100, making it easier for the end of the cutting edge 100 to reach the desired cutting position.

[0033] The bending design of the blade segment 110 increases the contact area of ​​the front end face of the blade 100, increases the cutting area, and allows for more even pressure distribution during cutting, thereby improving cutting efficiency.

[0034] In this embodiment, the opening of the through channel 101 is aligned with the blade section 110 to ensure that the light fully illuminates the surgical area, avoiding obstruction or shadows, thereby providing a better field of vision and operating environment, allowing the lighting lamp 600 to shine directly on the bent rod, making the cutting area of ​​the blade section 110 bright and easy to detect.

[0035] In this embodiment, the cross-sectional area of ​​the blade segment 110 gradually decreases from the rear end face to the front end face, which is more suitable for the movement of the blade segment 110, reduces movement resistance, and minimizes harm to the human body.

[0036] Preferably, the blade segment 110 further includes a first inclined end face 212 and a second inclined end face 213 disposed on the left and right sides. The surface of the first inclined end face 212 transitions to the surface of the connecting segment 120 and the front end face of the blade segment 110. One side of the surface of the second inclined end face 213 transitions to the front end face of the blade segment 110, and the other side of the surface is disposed on the front end face of the connecting segment 120.

[0037] The blade section 110 and the connecting section 120 are designed to form a cone-shaped structure with a smaller front and larger back to reduce the sliding resistance of the blade section 200. The first inclined end face 212 and the second inclined end face 213 further optimize the shape of the blade section 110, forming a cone-shaped structure that is more suitable for moving forward. On the other hand, the surface of the first inclined end face 212 transitions to the surface and top end face of the connecting section 120, making the outer side of the entire blade section 110 smoother.

[0038] In this embodiment, the front end face of the connecting segment 120 includes an arc-shaped inclined surface 221. One side of the arc-shaped inclined surface 221 transitions to the upper end face of the blade segment 110, and the other side of the arc-shaped inclined surface 221 transitions to the peripheral end face of the connecting segment 120.

[0039] The curved bevel 221, on the one hand, gives the blade 200 a cone-like structure that is pointed at the front and wide at the back, facilitating its movement through the human body and reducing tissue damage. On the other hand, the opening of the through-channel 101 is located on the bevel, preventing the light from the illumination lamp 600 from being blocked, and allowing for accurate acquisition of the current position of the blade tip 100 when used with an endoscope. Simultaneously, the curved bevel 221 makes the blade segment 110 more slender and easier to insert, and its smoother outer surface reduces unnecessary resistance and friction, making the blade segment 110 move more smoothly during operation.

[0040] In this embodiment, the lighting lamp 600 is also provided with a power supply line. The power supply line and the conductive line are integrally formed into a wire 510. The end of the wire 510 is connected to a plug 520. The plug 520 is provided with a multi-pin 521 structure. At least one pin 521 is the positive wire of the conductive line and at least one pin 521 is the positive wire of the power supply line.

[0041] The power supply line provides power to the lighting lamp 600. Simultaneously, the power supply line and conductive wire are integrated into a single cable 510, optimizing the wiring and simplifying the structure. This not only facilitates operation but also makes it convenient to use the scalpel device with lighting functionality. The plug 520 is a dedicated plug that can be used with a dedicated socket. The plug pin 521 also has a ground wire, forming a power supply circuit for the lighting lamp 600 through the positive terminal of the power supply line and the ground wire.

[0042] Furthermore, the top end of the wire 510 is connected to the lighting lamp 600, and a conductive wire extends from it. This conductive wire passes through the inner wall of the mounting cavity 102 and extends to the blade 100. The conductive wire enters from the inner wall of the mounting cavity 102, runs along the through channel 101, and reaches the mounting groove 211 of the blade 100, thereby achieving an electrical connection with the blade 100. The blade 100 is typically connected to a high-frequency power supply device via the conductive wire. One end of the conductive wire is connected to the output port of the high-frequency power supply device, and the other end is connected to the blade 100, ensuring that high-frequency current can flow through the metal blade 100, thereby generating high temperature and an electric arc for cutting and coagulation during surgery.

[0043] The blade 100 and the mounting groove 211 are fixedly connected, for example, by means of a complex shape, by means of injection molding, by means of adhesive bonding, or by means of interference fit.

[0044] In this embodiment, the end of the handle 400 includes a protruding opening 410, which connects to the end of the mounting cavity 102. The top of the mounting cavity 102 connects to the through channel 101. The mounting cavity 102 is inclined. The lighting lamp 600 enters the mounting cavity 102 through the protruding opening 410 and is fixed to the mounting cavity 102. The lighting lamp 600 and the mounting cavity 102 are sealed together, achieving a sealed arrangement between the inner and outer sides of the mounting cavity 102. The mounting cavity 102 is inclined, and the light emitted by the lighting lamp 600 enters the through channel 101 through the mounting cavity 102, then shines through the through channel 101 to the opening of the through channel 101, and finally exits outward.

[0045] In this embodiment, the end of the handle 400 is provided with another opening through the channel 101, and a switch valve structure 420 is provided therein; the switch valve structure 420 includes a valve body, a valve, a valve core and a seal. The valve body is usually a pipe and is located at the end of the mounting groove 211. The valve is rotary, push-pull, ball or other types and is located in the valve body to achieve sealing or opening of the valve body pipe. The valve core is a driving component that drives the movement of the valve to control the flow or sealing of the fluid. The valve seal is used to ensure the sealing performance when the valve is closed and to prevent fluid leakage.

[0046] The guide rod is inserted into the opening at the end of the handle 400 through the through channel 101, and extends all the way to the opening of the through channel 101, and abuts against the rear end face of the blade section 110, so that the blade part 200 and the extension part 300 are in a state of high hardness, which is determined according to the hardness and elasticity of the guide rod, so as to facilitate operation and insert the blade part 200 into the corresponding position of the human body.
