Description

Technical Field

[0001] This utility model relates to the field of high-energy surgical scalpels, and in particular to a dual-energy surgical scalpel. Background Technology

[0002] In modern surgery, high-frequency electrosurgical units and ultrasonic scalpels are two core energy devices, but their principles and clinical applications differ significantly: High-frequency electrosurgical units use high-frequency current to generate Joule heating for tissue cutting and coagulation. Their advantages include rapid hemostasis and lower cost, but they have limitations such as a large area of ​​thermal damage, excessive smoke generation, and difficulty in handling large blood vessels. Ultrasonic scalpels utilize piezoelectric ceramic transducers to convert electrical energy into high-frequency mechanical vibration (typically 55.5 kHz). Through cavitation and frictional heat, they achieve precise cutting and protein coagulation, characterized by minimal thermal damage (approximately 80-100°C) and less smoke. However, they are less effective at closing high-tension blood vessels (e.g., those with a diameter >5 mm).

[0003] In the prior art, electrosurgical units and ultrasonic scalpels are mostly independent devices. For example, the invention patent with smoke absorption function disclosed in CN115363700B discloses an anti-tangle ultrasonic surgical scalpel, which only has a single ultrasonic scalpel function; the utility model disclosed in CN219000525U discloses a medical electrosurgical head assembly structure and a multifunctional electrosurgical unit using the same, which only has a single electrosurgical function.

[0004] The main problems with this single-function scalpel in practical use are as follows:

[0005] 1. Low operational efficiency: Complex surgeries require frequent instrument changes, prolonging surgical time and increasing patient risk. 3. Functional limitations: The system cannot dynamically switch energy modes based on real-time intraoperative needs (such as tissue type and blood vessel diameter), lacking flexibility in areas like delicate nerve dissection (requiring low-thermal damage from an ultrasonic scalpel) and cutting thick, tough tissues (requiring efficient hemostasis from an electrocautery scalpel). 3. Instrument redundancy and cost pressure: Medical institutions must purchase two systems simultaneously, occupying operating room space and incurring high maintenance costs. Utility Model Content

[0006] In view of this, the present invention provides a dual-energy surgical knife to solve the above problems.

[0007] A dual-energy surgical scalpel includes a handle assembly, a conductive socket disposed on the handle assembly, an electrosurgical assembly connected to the conductive socket, and an ultrasonic component connected to the conductive socket. The ultrasonic component includes a transducer and two wires connecting the transducer to the conductive socket. The two wires are connected to the positive and negative poles of the ultrasonic component. The electrosurgical assembly includes a blade assembly and a second wire connecting the blade assembly to the conductive socket. The blade assembly includes a waveguide rod, an insulating tube sleeved around the waveguide rod, an inner sleeve disposed around the insulating tube, an outer sleeve disposed around the inner sleeve, an upper clamp connected to the inner sleeve and the outer sleeve via a pivot, and an ultrasonic blade tip disposed at one end of the waveguide rod. The waveguide rod is insulated from the outer sleeve. When using the electrosurgical assembly, the wire at one pole of the ultrasonic component is de-energized, and the electrosurgical assembly utilizes the other pole of the ultrasonic component. The second wire connects to the outer sheath to connect to the other pole of the electrosurgical unit, forming a complete circuit when the ultrasonic blade head and the upper jaw clamp and cut human tissue. Alternatively, both the first wire and the second wire can be energized, allowing the electrosurgical and ultrasonic functions to be implemented simultaneously.

[0008] Furthermore, the transducer includes a piezoelectric ceramic, a conductive post connected to the piezoelectric ceramic, and an electrode holder connected to the positive and negative electrodes of the piezoelectric ceramic through the conductive post. The electrode holder is provided with a large copper ring and a small copper ring respectively connected to the positive and negative electrodes of the piezoelectric ceramic.

[0009] Furthermore, the waveguide rod is screwed to the conductive post.

[0010] Furthermore, the dual-energy scalpel includes a universal wheel assembly disposed on the handle assembly. The handle assembly includes a spring piece disposed near the universal wheel assembly. The universal wheel assembly includes a conductive ring sleeved on the outer periphery of the universal wheel assembly and a spring pin disposed inside the universal wheel assembly. The conductive ring abuts against the spring piece, and the spring pin connects the conductive ring and the scalpel assembly.

[0011] Furthermore, the outer sleeve is disposed on the inner circumference of the universal wheel assembly, the second wire is connected to the spring piece, and is connected to the upper clamp through the conductive ring, the spring pin, and the outer sleeve.

[0012] Furthermore, the waveguide rod is provided with an insulating tube that is insulated from the outer sleeve by insulating the inner sleeve. The waveguide rod is limitedly connected to the universal wheel assembly and the sleeve adapter assembly. The inner sleeve is disposed on the inner circumference of the sleeve adapter assembly. The universal wheel assembly and the sleeve adapter assembly are made of insulating material.

[0013] Furthermore, the handle assembly includes a housing with a grip portion, the conductive socket being disposed on the grip portion and externally connected to an operating device from below the grip portion.

[0014] Furthermore, the dual-energy scalpel also includes a power button assembly connected to the conductive socket. The power button assembly includes a power button and at least two third wires connecting the power button and the conductive socket. The third wires provide power to the power button to achieve the function of adjusting the power.

[0015] Furthermore, the dual-energy scalpel also includes a mode switching button assembly connected to the conductive socket. The mode switching button assembly includes a mode switching button and a fourth wire connecting the mode switching button and the conductive socket. One pole of the mode button is connected to the third wire to borrow one pole of the power button assembly, and the other pole of the mode button is connected to the electrode holder through the fourth wire.

[0016] Compared with existing technologies, this utility model provides a dual-energy bipolar surgical scalpel equipped with an ultrasonic component, an electrosurgical component, and a mode switching button to achieve both electrosurgical and ultrasonic scalpel functions. The ultrasonic component is connected to a conductive socket via two wires to achieve the ultrasonic scalpel function. One end of the electrosurgical component is connected to a spring contact via a second wire, and then connected to the upper clamp via the spring contact, conductive coil, spring pin, and outer sleeve. The other pole is connected to a conductive post via a waveguide rod to utilize one pole of the ultrasonic component. The mode switching button is used to change the energization status of the wires (the non-shared poles of the ultrasonic component and the electrosurgical component) and the second wire to switch between ultrasonic and electrosurgical modes. When the non-shared pole wire is de-energized, the electrosurgical function is activated; when the second wire is de-energized, the ultrasonic scalpel function is activated. Alternatively, both the wires and the second wire can be energized, allowing the electrosurgical and ultrasonic functions to be activated simultaneously. Attached Figure Description

[0021] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0022] like Figures 1 to 4 The diagram shown is a structural schematic of a dual-energy ultrasonic scalpel provided by this utility model. The dual-energy ultrasonic scalpel includes a handle assembly 10, a conductive socket 20 disposed on the handle assembly 10, a caster wheel assembly 30 disposed on the handle assembly 10, an ultrasonic component 40 connected to the conductive socket 20, an electrosurgical component 50 connected to the conductive socket 20, a power button assembly 60 connected to the conductive socket 20, and a mode switching button assembly 70 connected to the conductive socket 20. It is conceivable that the dual-energy ultrasonic scalpel should also include other functional components, such as a smoking component, etc., all of which are prior art known to those skilled in the art.

[0023] The handle assembly 10 includes a housing 11, which includes a grip portion 111 and a spring piece 112 disposed near the universal wheel assembly 30. The handle assembly 10 is used to limit the circuit connection of the wire 42 to prevent the circuit connection from getting tangled with other functional components when they rotate, thereby avoiding damage to the circuit.

[0024] The conductive socket 20 is disposed on the grip portion 111 and an operating device is externally connected from below the grip portion 111 to avoid wire tangling.

[0025] The caster wheel assembly 30 includes a conductive ring 31 sleeved on the outer periphery of the caster wheel assembly 30, and a spring pin 32 disposed inside the caster wheel assembly 30. The conductive ring 31 abuts against the spring piece 112, and the spring pin 32 connects the conductive ring 31 and the electrosurgical assembly 50. The caster wheel assembly 30 is used to assist in the installation of the ultrasonic component 40 and the electrosurgical assembly 50, and to prevent damage during installation.

[0026] The ultrasonic component 40 includes a transducer 41 and two wires 42 connecting the transducer 41 to the conductive socket 20. The transducer 41 includes a piezoelectric ceramic 411, a conductive post 412 connecting the piezoelectric ceramic 411, and an electrode holder 413 connected to the positive and negative terminals of the piezoelectric ceramic 411 via the conductive post 412. The piezoelectric ceramic 411 converts electrical energy into high-frequency vibration. The conductive post 412 conducts electricity, assisting the operation of the electrosurgical unit 50. The electrode holder 413 has a large copper ring 4131 and a small copper ring 4132 respectively connected to the positive and negative terminals of the piezoelectric ceramic 411. The connection structure between the conductive post 412 and the electrode holder 413 is a common technology and will not be described in detail here.

[0027] The two wires 42 are connected to the positive and negative poles of the ultrasonic component 40 to provide power to the piezoelectric ceramic 411, which emits high-frequency vibrations to realize the function of an ultrasonic scalpel.

[0028] The electrosurgical unit 50 includes a cutting tool assembly 51 and a second wire 52 connecting the cutting tool assembly 51 and the conductive socket 20. The cutting tool assembly 51 includes a waveguide rod 511, an insulating tube 512 sleeved on the outer periphery of the waveguide rod 511, an inner sleeve 513 disposed on the outer periphery of the insulating tube 512, an outer sleeve 514 disposed on the outer periphery of the inner sleeve 513, an upper clamp 515 connected to the inner sleeve 513 and the outer sleeve 514 via a rotating shaft, and an ultrasonic cutting head 516 disposed at one end of the waveguide rod 511.

[0029] The waveguide rod 511 is insulated from the outer sleeve 514 to avoid short circuits. The insulating tube 512 is insulated from the outer sleeve 514 by insulating with the inner sleeve 513. Since the waveguide rod 511 is limitedly connected to the universal wheel assembly 30 and the sleeve adapter assembly, and the inner sleeve 513 is disposed on the inner circumference of the sleeve adapter assembly, and the universal wheel assembly 30 and the sleeve adapter assembly use insulating materials, they are insulated from the outer sleeve 514. The inner sleeve 513, outer sleeve 514, upper clamp 515, and ultrasonic cutter head 516 are common technologies and will not be described in detail here.

[0030] When using the electrosurgical unit 50, the lead wire 42 of one pole of the ultrasonic component 40 is de-energized, and the electrosurgical unit 50 utilizes the other pole of the ultrasonic component 40. The waveguide rod 511 is screwed to the conductive post 412. Since the conductive post 412 is conductive and connected to the electrode base 413, the waveguide rod 511 can connect to and utilize the lead wire 42 of the other pole of the transducer 41 assembly, thereby allowing current to be transmitted from the ultrasonic blade head 516 of the waveguide rod 511 to the lead wire 42, and also from the lead wire 42 to the ultrasonic blade head 516.

[0031] The second wire 52 connects to the outer sleeve 514 to connect to the other pole of the electrosurgical assembly 50. The outer sleeve 514 is disposed on the inner circumference of the universal wheel assembly 30. The second wire 52 connects to the spring piece 112 and is connected to the upper clamp 515 through the conductive ring 31, the spring pin 32, and the outer sleeve 514, so that current can be transmitted from the upper clamp 515 to the second wire 52, and vice versa. A complete circuit is formed when the ultrasonic blade head 516 clamps and cuts human tissue with the upper clamp 515.

[0032] The power button assembly 60 includes a power button 61 and at least two third wires 62 connecting the power button 61 and the conductive socket 20.

[0033] The power button 61 includes a maximum button and a minimum button. The maximum button and the minimum button are connected in parallel. The power button 61 is used to adjust the output power. The power button 61 is a common technology and will not be described in detail here.

[0034] The third wire 62 provides power to the power button 61, enabling the power adjustment function.

[0035] The mode switching button assembly 70 includes a mode switching button 71 and a fourth wire (not shown) connecting the mode switching button 71 and the conductive socket 20.

[0036] One pole of the mode switching button 71 is connected to the third wire 62 to utilize one pole of the power button assembly 60. The other pole of the mode switching button 71 is connected to the electrode base 413 via the fourth wire. The mode switching button 71 is used to switch between the ultrasonic and electrosurgical modes. The mode switching button 71 is a common technology and will not be described in detail here. The mode switching button 71 changes the mode by altering the energizing state of the wires 42 and 52 (which do not share a common pole) in the electrosurgical assembly 50 and the ultrasonic assembly 40. When the wire 42 is de-energized, the electrosurgical function is activated; when the second wire 52 is de-energized, the ultrasonic function is activated. Alternatively, both the wires 42 and 52 can be energized, allowing the electrosurgical and ultrasonic functions to be activated simultaneously.

[0037] Compared with the prior art, the present invention provides a dual-energy scalpel by incorporating an ultrasonic component 40, an electrosurgical component 50, and a mode switching button component 70 to achieve a dual-energy bipolar scalpel with switchable electrosurgical and ultrasonic scalpel functions. The ultrasonic component 40 is connected to the conductive socket 20 via two wires 42 to realize the ultrasonic scalpel function. One end of the electrosurgical component 50 is connected to the spring contact 112 via the second wire 52, and is connected to the upper clamp 515 via the spring contact 112, the conductive coil 31, the spring pin 32, and the outer sleeve 514. The other end is connected to the conductive post 412 via the waveguide rod 511 to utilize one end of the ultrasonic component 40. The mode switching button 71 is used to change the energizing status of the non-shared pole wire 42 and the second wire 52 of the ultrasonic component 40 and the electrosurgical component 50 to switch between ultrasonic scalpel and electrosurgical modes. When the non-shared pole wire 42 is not energized, the electrosurgical function is activated; when the second wire 52 is not energized, the ultrasonic scalpel function is activated. Alternatively, both wire 42 and the second wire 52 can be energized, allowing the electrosurgical and ultrasonic functions to be activated simultaneously.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
