Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable electrocoagulation hook for surgery. Background Technology

[0002] Electrocautery hooks are commonly used medical instruments in surgical procedures. By controlling the electrical energy output and time, they can achieve precise cutting, improving the cutting accuracy of the surgery. In addition, another important function of electrocautery hooks is hemostasis. By heating the tissue near the incision with electrical energy, the tissue is heated and adhered together, achieving the purpose of hemostasis. During the operation, in addition to electrocautery hooks, doctors may also use medical instruments such as electrocautery knives and electroacupuncture needles. However, ordinary electrocautery hooks do not have the function of switching between instruments. Doctors will frequently switch instruments during the operation, increasing the range of motion of the doctor and increasing the probability of secondary injury to the patient. Therefore, an adjustable electrocautery hook for surgery is designed to solve the above problems.

[0003] On January 18, 2022, Chinese Patent CN215534973U announced an adjustable electrocoagulation hook for urological surgery, comprising an electrocoagulation hook clamp, a first electrocoagulation tube, a power cord, and an electrocoagulation hook; one end of the first electrocoagulation tube is connected to the electrocoagulation hook clamp, and the other end is connected to the power cord; the open end of the electrocoagulation hook clamp is provided with an electrocoagulation hook; this utility model adds an adjustable electrocoagulation hook clamp to the original electrocoagulation hook and designs a variety of electrocoagulation hooks with different functions, including an electrocution hook, an electrocautery knife, and an electrocautery needle; in order to adapt to surgeries of different sizes, the main body of the electrocoagulation hook also has two different specifications, which greatly improves the practicality of the electrocoagulation hook.

[0004] The aforementioned prior art announcement describes an adjustable electrocoagulation hook for surgery, which adds an adjustable function to the electrocoagulation hook clamp, allowing it to hold not only the electrocoagulation hook but also instruments such as electrocautery knives and electroacupuncture needles. However, the aforementioned adjustable electrocoagulation hook for surgery does not have an automatic instrument switching function. Doctors must manually change the required instruments as needed, increasing the range of motion for doctors and the risk of secondary injury to patients. The changed instruments need to be manually disinfected before they can be changed and used again, making the operation cumbersome.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0042] To address the technical problem of surgeons frequently switching instruments and making large movements during surgery, which could easily cause secondary injury to patients, such as... Figure 1-13 As shown, the following preferred technical solutions are provided:

[0043] An adjustable electrocoagulation hook for surgery includes a gripping component 1 and a controller 2 fixedly mounted on the top of the gripping component 1. The gripping component 1 is designed to provide a good grip for the operator. The controller 2 controls and coordinates the various components. A power cord 3 is electrically connected to the controller 2 and connected to a power source to provide energy. An extension rod 4 is fixedly mounted on the bottom of the gripping component 1. A conversion component 5 is rotatably mounted at the lower end of the extension rod 4. Different instruments are mounted at both ends of the conversion component 5. By rotating the conversion component 5, different instruments can be switched. The instruments mounted at both ends of the conversion component 5 can be selectively mounted by the doctor according to the instruments required during the operation. A cleaning component 6, a disinfection component 7, and a wiping component 8 are respectively fixedly mounted in the lower end of the extension rod 4. The conversion component 5 rotates during instrument switching. During rotation, the used instruments first pass through the cleaning component 6 to wipe away residual blood and tissue fluid, and then continue rotating to the disinfection component 7 to disinfect the wiped instruments for the next use.

[0044] When the switching component 5 rotates again to switch instruments, the sterilized instruments will pass through the wiping component 8 to wipe away any residual disinfectant, preventing secondary damage to the patient's wound during use. The other instrument will then repeat the same steps. This process can be repeated to clean and sterilize instruments during the switching process, eliminating the need for frequent sterilization work, saving manpower, and reducing the risk of wound infection due to untimely instrument sterilization.

[0045] An internal sliding push assembly 9 is embedded in the extension rod 4, and is fixedly connected to the disinfection assembly 7. The push assembly 9 controls the amount of disinfectant on the disinfection assembly 7 to prevent excessive disinfectant from dripping onto the patient's wound. An internal sliding hydraulic assembly 10 is embedded in the extension rod 4 to drive the push assembly 9. A first compression assembly 20 and a second compression assembly 30 are respectively embedded and slidably arranged on the outer periphery of the conversion assembly 5. The hydraulic assembly 10 is engaged with the first compression assembly 20 and the second compression assembly 30. The hydraulic component 10 is driven by the hydraulic component 10, which in turn drives the drive component 9. The outer wall of the conversion component 5 is fixedly installed with a first terminal 40 and a second terminal 50. The extension rod 4 is internally fitted with a telescopic terminal 60, which is engaged with the first terminal 40 and the second terminal 50. The conversion component 5 can be powered on and off by the cooperation of the first terminal 40, the second terminal 50 and the telescopic terminal 60. The extension rod 4 is also internally fitted with a motor 70, which is fixedly connected to the conversion component 5.

[0046] The grip assembly 1 includes a grip 11 and several buttons 12 that are movably mounted on the outer periphery of the grip 11. A controller 2 is fixedly mounted on the top of the grip 11. All buttons 12 are electrically connected to the controller 2. The grip 11 is ergonomically designed to provide a good grip experience for the user. Pressing the buttons 12 will transmit electrical signals to the controller 2 to control the amount and duration of electrical output, as well as to control the switching of the device.

[0047] The extension rod 4 includes a rod body 41 fixedly installed at the bottom of the handle 11 and a U-shaped groove 42 opened in the middle of the bottom surface of the rod body 41. A cleaning component 6 and a wiping component 8 are fixedly installed on the top surface of the inner cavity of the U-shaped groove 42. A disinfection component 7 is also fixedly installed on the top surface of the inner cavity of the U-shaped groove 42. The cleaning component 6 and the wiping component 8 are fixedly arranged on both sides of the disinfection component 7, and the cleaning component 6, the disinfection component 7 and the wiping component 8 are arranged in a linear manner. A sealing plug 43 and a protective shell 44 are embedded and fixedly installed on the outer wall of the outer periphery of the rod body 41. Disinfectant can be added to the inside of the rod body 41 by removing the sealing plug 43. The sealing plug 43 is set to prevent the disinfectant from leaking inside the rod body 41. The protective shell 44 protects the motor 70.

[0048] A storage chamber 411 is formed in the center of the top surface of the U-shaped groove 42. The storage chamber 411 stores disinfectant. The storage chamber 411 is connected to the outer wall of the rod 41. A sealing plug 43 is embedded and fixed at the connection between the storage chamber 411 and the outer wall of the rod 41. The storage chamber 411 is connected to the disinfection component 7. A hydraulic chamber 412 is formed on one side of the rod 41. The hydraulic chamber 412 is connected to one side of the inner wall of the rod 41. The hydraulic chamber 412 contains hydraulic oil. The pushing component 9 is horizontally and slidably embedded in the upper end of the hydraulic chamber 412. The hydraulic component 10 is horizontally and slidably embedded in the hydraulic chamber 412. At the lower end, when the hydraulic component 10 is in operation, the hydraulic oil in the hydraulic chamber 412 can drive the component 9 to operate. A first chamber 413 is provided on one side of the lower end of the rod 41. The motor 70 is embedded and fixedly installed in the inner cavity of the first chamber 413. The first chamber 413 is connected to the outer wall of the rod 41. The protective shell 44 is embedded and fixedly installed at the connection between the first chamber 413 and the outer wall of the rod 41. The output end of the motor 70 passes through the inner end side wall of the first chamber 413. A second chamber 414 is provided on the other side of the lower end of the rod 41. The second chamber 414 is connected to the inner wall of the other side of the rod 41. The telescopic terminal 60 is embedded and slidably installed in the inner cavity of the second chamber 414.

[0049] The conversion assembly 5 includes a rotating rod 51 embedded and rotatably mounted on the inner walls of both sides of the inner cavity of the U-shaped groove 42, and an electrocoagulation hook 52 and an electric knife 53 respectively threaded to both ends of the rotating rod 51. A pair of sliding grooves 54 are provided on the outer wall of the outer periphery of the rotating rod 51, and a first extrusion assembly 20 and a second extrusion assembly 30 are respectively embedded and slidably mounted in the inner cavity of the pair of sliding grooves 54.

[0050] The rotating rod 51 includes a rotating rod body 511 embedded and rotatably mounted on the inner walls of both sides of the inner cavity of the U-shaped groove 42, and a pair of rotating shafts 512 fixedly mounted on the outer wall of the outer periphery of the rotating rod body 511. The two rotating shafts are symmetrically arranged, and the rotating shaft on one side of the rotating rod body 511 is fixedly connected to the output end of the motor 70.

[0051] The electrosurgical knife 53 includes a cutting head 531 threadedly connected to the upper end of the rotating rod body 511 and a fixed terminal 532 fixedly installed in the middle of the top surface of the inner cavity of the cutting head 531. The fixed terminal 532 is inserted into the rotating rod body 511. Except for the cutting tool, the electrosurgical knife 53 and the electrocoagulation hook 52 have the same composition and connection method. When the electrosurgical knife 53 and the electrocoagulation hook 52 are installed at both ends of the rotating rod body 511, the fixed terminal 532 will be inserted into the rotating rod body 511, so that the electrosurgical knife 53 and the electrocoagulation hook 52 can be energized to perform cutting and hemostasis.

[0052] The telescopic terminal 60 includes a first electromagnet 601 embedded and fixedly installed on the inner wall of the second chamber 414 and a movable terminal 602 slidably installed in the inner cavity of the second chamber 414. The movable terminal 602 forms a snap-fit ​​relationship with the first terminal 40 and the second terminal 50 respectively, and the movable terminal 602 is elastically connected to the inner wall of the second chamber 414 by a first spring 603. When switching instruments, the first electromagnet 601 is energized, and under the action of magnetic force, the movable terminal 602 will retract into the inner cavity of the second chamber 414, releasing the snap-fit ​​relationship with the first terminal 40 or the second terminal 50, so that the switching component 5 is in a de-energized state. When the instrument switching is completed, the first electromagnet 601 is de-energized, and under the action of the elastic force of the first spring 603, the movable terminal 602 will extend out of the second chamber 414, restoring the snap-fit ​​relationship with the first terminal 40 or the second terminal 50, so that the switching component 5 returns to the on / off state.

[0053] When the instrument needs to be changed, the telescopic terminal 60 is energized and retracts into the extension rod 4, disengaging from the first terminal 40 and disconnecting the power supply to the conversion assembly 5. Simultaneously, the first compression assembly 20 remains energized, continuously retracting into the conversion assembly 5, thus disengaging from the hydraulic assembly 10. The hydraulic assembly 10, under the thrust of the pushing assembly 9, extends outward from the extension rod 4. At this point, the controller 2 starts the motor 70, which drives the conversion assembly 5 to rotate and switch instruments. Once the rotation reaches 180°, the instrument switching is complete. Then, the second compression assembly 30 is de-energized and extends out from the conversion assembly 5 to engage with the first terminal 4. On the hydraulic assembly 10, the hydraulic assembly 10 is pushed inward toward the extension rod 4 to drive the push assembly 9. At the same time, the telescopic terminal 60 is de-energized and extends outward toward the extension rod 4 to engage with the second terminal 50, restoring the conversion assembly 5 to the energized state. By repeating the above operation, continuous switching of instruments can be achieved. With the above settings, doctors can independently operate and change the required instruments during surgery without the need for other personnel to pass them on. This not only saves surgical time but also reduces the range of motion of the doctor and reduces the risk of secondary injury to the patient. Doctors can install different instruments on the conversion assembly 5 according to the instruments required for different surgeries, which has good flexibility and strong practicality.

[0054] To address the technical problem of inadequate cleaning of switched instruments, which could easily lead to wound infection in patients, such as... Figure 2 , Figure 4 , Figure 8 and Figure 11 As shown, the following preferred technical solutions are provided:

[0055] The cleaning assembly 6 includes a fixed plate 61 fixedly installed on the top surface of the inner cavity of the U-shaped groove 42 and a pair of support frames 62 fixedly installed on the bottom surface of the fixed plate 61. A cleaning plate 63 is fixedly installed on each of the pair of support frames 62.

[0056] When switching instruments, the rotating rod 51 drives the electrocautery hook 52 and the electrosurgical knife 53 to rotate. The electrocautery hook 52 or the electrosurgical knife 53 will first slide between the two cleaning plates 63, so that the cleaning plates 63 clean the blood and tissue fluid remaining on the surface of the electrocautery hook 52 or the electrosurgical knife 53. Through the above settings, the instruments after use can be initially cleaned during the instrument switching process, so as to improve the cleanliness of the instruments and prevent infection of the patient's wound caused by unclean instruments.

[0057] To address the issues of frequent disinfection of equipment after switching, which wastes manpower, and the technical challenges of controlling disinfectant seepage and preventing it from dripping onto patient wounds, such as... Figure 2 , Figure 4-5 , Figure 8 and Figure 11-13 As shown, the following preferred technical solutions are provided:

[0058] The disinfection component 7 includes a hollow fixing block 71 that is fixedly installed on the top surface of the inner cavity of the U-shaped groove 42 and a sealing plate 72 that is embedded and slidably disposed in the hollow fixing block 71. The sealing plate 72 is fixedly connected to the pushing component 9. Several through holes 73 are provided on the top surface of the hollow fixing block 71. A pair of disinfection plates 74 are fixedly installed on the bottom surface of the hollow fixing block 71, and the pair of disinfection plates 74 are connected to the storage chamber 411 through several through holes 73.

[0059] The wiping assembly 8 includes a load-bearing plate 81 fixedly installed on the top surface of the inner cavity of the U-shaped groove 42 and a pair of wiping plates 82 fixedly installed on the bottom surface of the load-bearing plate 81.

[0060] The pushing component 9 includes a slider 91 that is horizontally embedded and slidably installed in the upper inner cavity of the hydraulic chamber 412. The slider 91 is fixedly connected to the sealing plate 72, and the slider 91 is elastically connected to the side wall of the inner cavity of the hydraulic chamber 412 by a second spring 92. The hydraulic component 10 drives the slider 91 to slide horizontally in the inner cavity of the hydraulic chamber 412 by squeezing the hydraulic oil in the hydraulic chamber 412. The slider 91 drives the sealing plate 72 to move together to control the amount of disinfectant seepage, while the second spring 92 plays the role of returning the slider 91 to its original position.

[0061] The hydraulic component 10 is horizontally embedded and slidably installed in the lower end cavity of the hydraulic chamber 412. The extrusion block 101 is movably connected to the side wall of the inner cavity of the hydraulic chamber 412 by a pull rope 102. The pull rope 102 limits the extrusion block 101 and prevents the extrusion block 101 from falling out of the inner cavity of the hydraulic chamber 412.

[0062] An adjustable electrocoagulation hook for surgery according to claim 9, characterized in that: the first compression assembly 20 includes a second electromagnet 201 embedded and fixedly installed on the side wall of the inner cavity of the slide groove 54 and a push rod 202 embedded and slidably installed in the inner cavity of the slide groove 54. The push rod 202 is elastically connected to the side wall of the inner cavity of the slide groove 54 by a third spring 203. The push rod 202 and the compression block 101 are in a snap-fit ​​relationship. The composition structure and connection method of the first compression assembly 20 and the second compression assembly 30 are the same. When the second electromagnet 201 is energized, the push rod 202 will retract into the inner cavity of the slide groove 54 under the action of magnetic force, and the force applied to the compression block 101 will be removed. The compression block 101 will extend outward under the action of the pushing assembly 9.

[0063] When switching instruments, the first compression assembly 20 remains energized, causing it to retract continuously into the conversion assembly 5. This removes the thrust applied to the hydraulic assembly 10. Under the thrust of the pushing assembly 9, the hydraulic assembly 10 extends outwards towards the extension rod 4. During this movement, the pushing assembly 9 moves the sealing plate 72, causing it to misalign with the through hole 73. At this time, the disinfectant in the storage chamber 411 permeates through the through hole 73 onto the disinfection plate 74 to disinfect the used instruments. After the instrument switching is complete, the second compression assembly 30 is de-energized and extends out from the conversion assembly 5, engaging with the hydraulic assembly 4. Pressure is applied to the hydraulic component 10, causing it to squeeze the hydraulic oil in the hydraulic chamber 412. This, in turn, drives the push component 9 to slide within the hydraulic chamber 412, causing the push component 9 to reset the sealing plate 72 and seal the through hole 73. This setup controls the amount of disinfectant seepage, preventing excessive seepage and dripping onto the patient's wound, which could cause secondary injury. When switching instruments, the disinfected instruments will pass through the wiping plate 82 during rotation to wipe away any residual disinfectant, preventing it from dripping onto the patient's wound as the instruments rotate.
