Abstract
Description
Technical Field
[0001] This application belongs to the field of medical equipment cleaning technology, specifically relating to an ultrasonic scalpel head cleaning device. Background Technology
[0002] Ultrasonic hemostasis systems, as key instruments in modern minimally invasive surgery, mainly consist of a high-frequency vibration generator, transducer assembly, titanium alloy ultrasonic scalpel tip, and multifunctional clamping mechanism. Their core working principle is based on the piezoelectric effect, generating 55.5kHz high-frequency mechanical vibration. The longitudinal vibration displacement is controlled within the range of 50-100μm through a scalpel tip amplitude amplification device. This vibrational energy generates instantaneous high temperatures (70-100℃) at the tissue contact surface through mechanical friction. Combined with the cavitation effect, this induces a phase transition of water within tissue cells, promoting the denaturation and cross-linking of collagen and elastin, forming a dense three-dimensional network hemostatic matrix.
[0003] Currently, the ultrasonic hemostasis devices used in clinical practice generally use FDA-certified DLC diamond-like carbon coated blades. Although they have excellent biocompatibility and wear resistance, they still have significant technical defects in the process of performing tissue cutting (especially in the blood-rich liver parenchyma or thyroid capsule): (1) Tissue dehydration and carbonization caused by vibration heat effect will adhere to the blade surface by van der Waals forces; (2) About 15%-23% of cases will have capillary oozing (<5ml / min), which mixes with lymph fluid to form a biocolloid covering the surgical field; (3) The current disposable blade design is limited by the aseptic packaging requirements. Its clamping surface lacks a directional irrigation channel, which requires the use of an additional 5Fr irrigation catheter for intermittent irrigation during the operation. This operation not only increases the average operation time by 15-20%, but may also cause fluctuations in pneumoperitoneum pressure due to instrument switching.
[0004] It is particularly important to note that unremoved adhering material can form a thermal resistance layer, causing the effective vibration energy of the scalpel head to decrease by more than 30%. This not only reduces cutting efficiency but may also lead to increased thermal damage to surrounding tissues due to abnormal heat conduction. The American College of Surgeons (ACS) 2022 Technical White Paper clearly states that the incidence of secondary bleeding due to tissue adhesion in complex hepatobiliary surgery using existing ultrasonic scalpels is as high as 8.7%, significantly higher than that of conventional electrosurgical equipment. Utility Model Content
[0005] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide an ultrasonic scalpel head cleaning device. This application can rinse the cutting clamp during the process of cutting and hemostasis with ultrasonic scalpel, and rinse the surgical area at the same time. This can not only ensure the use effect of the cutting clamp, but also improve the visibility of the surgical field.

[0025] The attached figure shows the preferred embodiment of the ultrasonic scalpel head cleaning device. The present application will be further described in detail below with reference to the attached figure.
[0026] like Figure 1-4 As shown, this embodiment provides an ultrasonic scalpel head cleaning device, which can be detachably mounted on an existing ultrasonic scalpel. The ultrasonic scalpel includes an ultrasonic scalpel body 1, a control rod 2 is provided on the ultrasonic scalpel body 1, and a cutting clamp 3 is provided at the end of the cutting clamp 3.
[0027] The ultrasonic scalpel head cleaning device includes a rinsing fluid box 4, which is detachably mounted on the ultrasonic scalpel body 1. The rinsing fluid box 4 is equipped with a cutting clamp rinsing mechanism 5 for rinsing the cutting clamp 3. A nozzle disassembly and positioning mechanism 6 for fixing the cutting clamp rinsing mechanism 5 is provided on the control rod 2 and the cutting clamp rinsing mechanism 5. A mounting base 7 is fixedly mounted on the bottom of the rinsing fluid box 4. The mounting base 7 is equipped with a box clamping and disassembly mechanism 8 for clamping and fixing the rinsing fluid box 4. A microcontroller 9 and a battery 10 are also provided on the mounting base 7.
[0028] The cutting clamp 3 is closed by adjusting the ultrasonic scalpel body 1. The spray end of the cutting clamp flushing mechanism 5 can be fixed to the control rod 2 and the cutting clamp 3 by the nozzle disassembly and positioning mechanism 6. The flushing fluid box 4 can be fixed to the ultrasonic scalpel body 1 by the box clamping and disassembly mechanism 8. A certain amount of flushing fluid is added to the flushing fluid box 4 in advance. Medical personnel operate the cutting clamp 3 to cut the tissue through the ultrasonic scalpel body 1. After cutting, the microcontroller 9 controls the cutting clamp flushing mechanism 5 to flush the blood and tissue fluid at the cut site of the patient's tissue. This process can be repeated after each cut. The tissue is clear during cutting, avoiding blood, tissue fluid and tissue fragments from clumping and obstructing the cutting path. After the operation is completed, the cutting clamp 3 is closed again. The cutting clamp flushing mechanism 5 is removed from the cutting clamp 3 by the nozzle disassembly and positioning mechanism 6. Then the box clamping and disassembly mechanism 8 is released from the ultrasonic scalpel body 1. The device can then be removed for cleaning and disinfection, which is convenient for the next use. The battery 10 can power the operation of the device, which does not require an external power source, making it convenient to use.
[0029] In this embodiment of the utility model, specifically, the cutting clamp rinsing mechanism 5 includes a micro pump 51 disposed on the rinsing liquid box 4. The inlet and outlet ends of the micro pump 51 are provided with a pumping pipe 52. A set of pumping pipes 52 are located on the inner and outer sides of the rinsing liquid box 4 respectively. A diverter 53 is fixedly installed on one pumping pipe 52.
[0030] A conduit 54 is fixedly installed on the diverter 53, a first conduit 55 is fixedly installed on the conduit 54, a second conduit 56 is fixedly installed on the first conduit 55, a collector 57 is fixedly installed on the second conduit 56, a diverter pipe 58 is fixedly installed on the collector 57, and an annular nozzle 59 is fixedly installed on the diverter pipe 58.
[0031] To flush the patient's tissue during cutting, a micro-pump 51 is activated by a micro-controller 9. The micro-pump 51 delivers the flushing fluid from the flushing fluid box 4 to a diverter 53 via a delivery tube 52. The fluid is then diverted through the diverter 53 into a set of first conduits 55, then into a second conduit 56, and finally into a collector 57. The fluid is then diverted again through the collector 57 into a set of diverting tubes 58, and finally into an annular nozzle 59. The annular nozzle 59 sprays the fluid onto the patient's tissue cutting site, flushing away blood and tissue fluid. This process can be repeated after each cut, ensuring clear tissue during cutting and preventing blood, tissue fluid, and tissue fragments from clumping and obstructing the cutting path.
[0032] In this embodiment of the utility model, specifically, the nozzle disassembly and positioning mechanism 6 includes a threaded groove 61 formed on the control rod 2, a threaded sleeve 62 and a platform-shaped fastening member 63 are sleeved on the control rod 2, and a threaded protrusion 64 is provided inside the threaded sleeve 62, which is adapted to the threaded groove 61.
[0033] To facilitate the installation of the cutting clamp flushing mechanism 5 on the control rod 2, the cutting clamp 3 is closed by adjusting the ultrasonic scalpel body 1, then the platform-shaped clamping part 63 is placed on the control rod 2, and the threaded sleeve 62 is screwed into the control rod 2 through the threaded groove 61. The end of the threaded sleeve 62 abuts against the platform-shaped clamping part 63, which can fix the platform-shaped clamping part 63 on the cutting clamp 3.
[0034] In this embodiment of the utility model, specifically, the box clamping and disassembly mechanism 8 includes a double-ended lead screw 81 rotatably installed in the mounting base 7, a lead screw sleeve 82 sleeved on the double-ended lead screw 81, a clamping plate 83 slidably installed in the mounting base 7, the clamping plate 83 being fixedly installed on the lead screw sleeve 82, and an anti-slip pad 84 being fixedly installed on the clamping plate 83.
[0035] To facilitate the fixing and removal of the irrigation fluid box 4, a set of clamping plates 83 is positioned between the ultrasonic scalpel bodies 1, and the knob 85 is rotated. Rotating the knob 85 will cause the double-ended lead screw 81 to rotate, which will cause a set of lead screw sleeves 82 to move and move closer to each other on the double-ended lead screw 81. Thus, the ultrasonic scalpel body 1 can be clamped and fixed by the set of clamping plates 83. The anti-slip pad 84 directly contacts the ultrasonic scalpel body 1 to increase contact friction and improve contact stability. The irrigation fluid box 4 can be fixed on the ultrasonic scalpel body 1. The set of clamping plates 83 can be released from the ultrasonic scalpel body 1 to remove the irrigation fluid box 4 from the ultrasonic scalpel body 1.
[0036] In this embodiment of the utility model, a knob 85 is fixedly installed at one end of the double-ended lead screw 81, and a limit ring 86 is fixedly sleeved on the double-ended lead screw 81.
[0037] To limit the movement of the double-ended lead screw 81 and facilitate its rotation, the knob 85 is turned, which will drive the double-ended lead screw 81 to rotate. The limiting ring 86 can limit the movement of the double-ended lead screw 81 and prevent it from moving left and right on the mounting base 7.
[0038] In use, the ultrasonic scalpel body 1 is adjusted to close the cutting clamp 3. Then, the platform-shaped clamping piece 63 is placed on the control rod 2, and the threaded sleeve 62 is screwed into the control rod 2 through the threaded groove 61. The end of the threaded sleeve 62 abuts against the platform-shaped clamping piece 63, which can fix the platform-shaped clamping piece 63 on the cutting clamp 3. Then, a set of clamping plates 83 are positioned between the ultrasonic scalpel bodies 1, and the knob 85 is rotated. The rotation of the knob 85 will drive the double-ended lead screw 81 to rotate. The rotation of the double-ended lead screw 81 will drive a set of lead screw sleeves 82 to move on the double-ended lead screw 81 and move closer to each other. Thus, the ultrasonic scalpel body 1 can be clamped and fixed by a set of clamping plates 83. The anti-slip pad 84 directly contacts the ultrasonic scalpel body 1 to increase contact friction and improve contact stability. The limiting ring 86 can limit the movement of the double-ended lead screw 81 and prevent the double-ended lead screw 81 from moving left and right on the mounting base 7. A certain amount of rinsing fluid is added to the rinsing fluid box 4 beforehand. Medical personnel use the ultrasonic scalpel body 1 to operate the cutting clamp 3 to cut the tissue. After cutting, the micro-controller 9 controls the micro-pump 51 to start. The micro-pump 51 delivers the rinsing fluid in the rinsing fluid box 4 to the diverter 53 through the suction tube 52. The diverter 51 then diverts the fluid to a first set of catheters 55, and through the first catheter 55 it enters the second catheter 56. The fluid then enters the collector 57 through the second catheter 56 and merges with the second catheter 56. The fluid is then diverted again through the collector 57 to a set of diverting tubes 58, and through the set of diverting tubes 58 it enters the annular nozzle 59. The annular nozzle 59 sprays the fluid onto the tissue cutting site of the patient to rinse the blood and tissue fluid at the tissue cutting site. This process can be repeated after each cutting. The tissue is clear during cutting, and blood, tissue fluid and tissue fragments are avoided from clumping and obstructing the cutting path. After the operation is completed, close the cutting clamp 3 again, unscrew the threaded sleeve 62 from the control rod 2 and the cutting clamp 3, and then loosen a set of clamps 83 from the ultrasonic scalpel body 1. The device can then be removed for cleaning and disinfection, making it convenient for the next use. The battery 10 can power the operation of the device, so no external power supply is required, making it convenient to use.
[0039] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
