Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an electrocoagulation hemostasis device for ophthalmic surgery. Background Art

[0002] Electrocoagulation hemostasis instruments have become one of the important tools in current surgeries, playing an important role in various surgical hemostasis and tissue cutting. In various external ophthalmic surgeries such as pterygium resection, double eyelid correction, eyelid mass resection, conjunctival mass removal, dacryocystorhinostomy, and ophthalmic plastic and cosmetic surgery, thorough and safe hemostasis is required during the operation. Different tissues have different requirements for the current magnitude of electrocoagulation hemostasis. The hemostasis current intensity on the bulbar conjunctiva and scleral surface needs to be lower to prevent serious complications such as perforation of the eyeball tissue. The hemostasis current power for muscles and skin can be slightly stronger.

[0003] Currently, the main components of the currently applied electrocoagulation hemostasis instruments include a main unit and a handle connected with an electrode head. The main unit and the handle are connected through a cable to achieve the purpose of electrical conduction. However, when the handle rotates, it is easy to cause the cable to wind, resulting in physical damage or accidental disconnection, thus affecting the surgical process. In addition, the electrode head has a high temperature, which will cause the blood around the electrode head to quickly coagulate and dry, coating the electrode head, thus resulting in the phenomenon of "sticking knife". When the electrode head is coated with dried blood, the current cannot be transmitted to the tissue area, resulting in the loss of the hemostasis function. Therefore, there is room for improvement and development in view of the above problems. Summary of the Invention

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope that the present invention can implement.

[0020] Example 1, in combination with Figures 1 to 8 As shown, this embodiment provides an electrocoagulation hemostasis device for ophthalmic surgery, including a housing 1 and an electrode assembly 3. The electrode assembly 3 includes an electrode head 39 having two electrodes and an insulating sleeve 35. The two electrodes are close to each other and insulated from each other. The electrode head 39 is movably sleeved in the insulating sleeve 35; A cooling module 7, connected to the electrode assembly 3 for inputting or outputting a cooling medium; A power supply module 5, electrically connected to the electrode assembly 3 and the cooling module 7 respectively. The power supply module 5 has a USB interface and is connected to an external DC power supply through a Micro USB jack to supply power to the electrode assembly 3 and the cooling module 7; A control module 6, used to control the working state of the power supply module 5. Among them, the working state of the power supply module 5 includes an on state and an off state; A key module 2, used to conduct or disconnect the electrical connection between the power supply module 5 and the electrode assembly 3, and control the working state of the cooling module 7. The control module 6 has a circuit board, and the circuit board can capture and process the operation instructions of the key module 2 to allow the user to set the power or other parameters.

[0021] Micro USB is smaller than the traditional USB interface, which allows the user to conveniently insert devices that support USB DC output, such as mobile phones, computers, power banks, etc., and can ensure sufficient contact area to ensure good electrical contact, so as to achieve the charging function.

[0022] Exemplarily, the housing 1 is composed of two butt-jointed housing components, which are firmly connected together by screws to have a high connection strength and can also be conveniently disassembled for maintenance or replacement of internal functional components. The housing 1 is formed with a slot 13, and each functional module is sequentially received in the slot 13. Both housing components are disposed in grooves, and the two grooves are butted to form the slot 13 and an interface. Each functional module is sequentially arranged in the slot 13. Among them, the cooling module 7 is disposed at the head of the housing 1, and the power module 5 is disposed at the tail interface of the housing 1 for convenient insertion into the device. The device and the USB interface can be connected through a data cable to achieve the charging function. Integrating each function into the housing 1 can significantly reduce the volume of the device, make the arrangement of each functional module more compact, and thus facilitate operation.

[0023] The control module 6 includes a high-frequency generator that generates high-frequency current. The high-frequency current is introduced into the human tissue through the electrode head 39 to generate a thermal effect inside the tissue, thereby achieving the purpose of hemostasis. The high-frequency generator is connected to the power module 5 to provide a stable power supply. The control module 6 is integrated with a monitoring and protection circuit to ensure the safety and reliability of the device. The button module 2 includes a power-on / off button and a power parameter adjustment button. The power-on / off button is used to conduct or disconnect the electrical connection between the power module 5 and the electrode assembly 3 and control the working state of the cooling module 7. The power parameter adjustment button can select the required power. The signal is transmitted to the circuit board, and the circuit board adjusts the output power according to the control signal. The output electrical signal is transmitted to the high-frequency generator, and the electrical signal is converted into high-frequency current to perform electrocoagulation operation. The high-frequency current is transmitted to the target tissue area through the electrode head 39, thereby achieving the purpose of hemostasis in the eye.

[0024] Exemplarily, the housing 1 has a wire routing cavity, and the cable connected between the electrode head 39 and the power module 5 is disposed in the wire routing cavity. The wire routing cavity is opened in the wall of the housing 1 (not shown in the figure). The wire routing cavity can provide a path for the cable connected between the electrode head 39 and the power module 5 and can also arrange the connection cables of each functional module in an orderly manner, avoiding messy wiring situations and making the internal layout of the device more tidy and clear.

[0025] Specifically, when the electrode head 39 is coated with dried blood, the current cannot be transmitted to the tissue area, resulting in the loss of the hemostasis function. To solve the above problems, a cooling module 7 is installed in the housing 1. The cooling module 7 is in communication with the electrode assembly 3, so that the cooling medium of the cooling module 7 can flow into the electrode assembly 3, thereby realizing the cooling function of the electrode head 39. The housing 1 is provided with a first air vent 11 and a second air vent 17, and the first air vent 11 and the second air vent 17 correspond to the cooling module 7. Both the first air vent 11 and the second air vent 17 are in communication with the slot 13. The first air vent 11 is provided at the joint of the two housing components. The cooling module 7 is arranged in the area between the first air vent 11 and the second air vent 17. The cooling module 7 includes a driving part. The driving ports of the driving part are respectively docked with the first air vent 11 and the second air vent 17. The driving port docked with the second air vent 17 is used for inputting or outputting the cooling medium, and the driving port docked with the first air vent 11 is used for transmitting the cooling medium to the electrode assembly 3, so that there is a flow of cooling medium around the electrode assembly 3, which can absorb the heat of the electrode assembly 3, and thus realize the cooling of the electrode assembly 3.

[0026] In this embodiment, the driving part includes a thermoelectric cooler and micro fans respectively arranged at the hot end and the cold end of the thermoelectric cooler. The micro fan at the hot end of the thermoelectric cooler corresponds to the second air vent 17, and the micro fan at the cold end of the thermoelectric cooler corresponds to the electrode assembly 3. Among them, the cold energy generated by the thermoelectric cooler provides the cooling medium for the electrode assembly 3, and the heat energy generated is output by the micro fan at the hot end for dissipating the heat at the hot end to ensure the refrigeration effect at the cold end, thereby enhancing the cooling efficiency of the electrode assembly 3.

[0027] In this embodiment, a bracket 16 is provided between the cooling module 7 and the control module 6. The bracket 16 has an air passage 15, and the air passage 15 can allow the cooling medium to flow to the tail of the housing 1, thereby realizing the overall cooling function of the housing 1.

[0028] Exemplarily, in combination with Figure 5As shown, a cooling rack 8 is connected between the cooling module 7 and the electrode assembly 3. The cooling rack 8 is provided with at least one cooling channel, and the cooling channel is connected to the electrode assembly 3 to absorb the heat of the electrode head 39 by using a cooling medium. In this embodiment, the cooling rack 8 is provided with two cooling channels, namely a first cooling channel 82 and a second cooling channel 83. The first cooling channel 82 communicates with the driving port of the electrode assembly 3 and the driving part. The cooling medium in the first cooling channel 82 flows to the electrode assembly 3 to take away the heat of the electrode assembly 3. A communication port 84 is provided between the second cooling channel 83 and the first cooling channel 82 to make them communicate with each other. The cooling rack 8 is provided with a first output port 81 corresponding to the second cooling channel 83 and the first air outlet 11. The first output port 81 realizes the output of the cooling medium in the second cooling channel 83, and the cooling medium flowing in the second cooling channel 83 realizes the heat dissipation function of each functional device in the housing 1.

[0029] In specific applications, the cooling module 7 generates cold energy through a semiconductor refrigeration chip, so that the cold energy flows through the first cooling channel 82 and the second cooling channel 83 and is transmitted to the electrode assembly 3 and the housing 1, realizing the rapid cooling of the electrode head 39 and each functional device in the housing 1 and enhancing the overall cooling efficiency.

[0030] Specifically, an electrode ring is provided at the connection between the housing 1 and the electrode assembly 3. The electrode ring is adjacent to the head of the housing 1. The electrode ring connects the high-frequency generator and the electrode head 39. The high-frequency current generated by the high-frequency generator is transmitted to the electrode head 39 through the electrode ring, so as to play a role in current conduction. The two electrodes provided on the electrode head 39 are a first electrode and a second electrode respectively. The first electrode and the second electrode are opposite and insulated from each other. When the two electrodes clamp the tissue, the current only passes between the two electrodes and directly acts on the target tissue area, making the application of energy very concentrated and reducing the influence on the surrounding non-target tissues. To further improve the cooling efficiency of the electrode head 39, a cooling medium flow cavity 391 for the cooling medium to flow is formed in the electrode head 39. A cooling pipe 4 is provided in the cooling medium flow cavity 391. The cooling pipe 4 includes a cooling inlet pipe 41 and a cooling return pipe 42. The cooling inlet pipe 41 is connected to the cooling module 7, and the cooling return pipe 42 is arranged in the housing 1. The cooling pipe 4 is laid along the path of the cooling medium flow cavity 391. The driving part of the cooling module 7 drives the cooling medium to be transmitted to the cooling inlet pipe 41 through the first cooling channel 82. The pipe orifices of the cooling inlet pipe 41 and the cooling return pipe 42 are communicated. The pipe orifice of the cooling return pipe 42 is communicated with the second cooling channel 83. The cooling medium flowing to the head of the cooling inlet pipe 41 is output to the second cooling channel 83 through the cooling return pipe 42 and is output from the first air outlet 11. During the process of the cooling medium flowing in the cooling inlet pipe 41, the heat of the electrode head 39 is taken away by the cooling medium, so as to realize the cooling function of the electrode head 39.

[0031] Exemplarily, the cooling inlet pipe 41 is spirally coiled within the cooling medium flow cavity 391. The spirally arranged cooling inlet pipe 41 can enable the cooling medium to flow uniformly along the cooling medium flow cavity 391 of the electrode head 39, relatively increasing the total length of the pipeline, so that the cooling medium has more time and surface area to exchange heat with the electrode head 39, thereby improving the overall heat exchange efficiency.

[0032] Exemplarily, a number of heat conducting fins 34 are provided within the cooling medium flow cavity 391. The heat conducting fins 34 are in contact with the pipe wall of the cooling inlet pipe 41 for absorbing the heat of the electrode head 39. This enables the heat of the electrode head 39 to be conducted to the surface of the heat conducting fins 34 more quickly and further conducted to the cooling inlet pipe 41 to improve the heat conduction efficiency and make the heat dissipation more rapid and effective. Multiple protrusions are provided on the surface of the heat conducting fins 34, thereby increasing the surface area in contact with the cooling medium and further accelerating the cooling speed.

[0033] Specifically, the electrode assembly 3 is detachably connected to the housing 1. A connection seat 12 is provided at the head of the housing 1, and the electrode assembly 3 is provided with a card slot 32 corresponding to the connection seat 12. The connection seat 12 and the card slot 32 are snap-connected. The electrode assembly 3 includes a sleeve 31. The sleeve 31 is sleeved on the outer wall of the electrode head 39. The head of the electrode head 39 is located outside the sleeve 31. An insulating sleeve 35 is sleeved on the outer wall of the sleeve 31. A card slot 32 is provided at the pipe orifice of the sleeve 31 relative to the housing 1. The tail of the electrode head 39 is located outside the pipe orifice of the sleeve 31 and is inserted into contact with the electrode ring on the housing 1. The card slot 32 is of an annular structure. The connection seat 12 is provided with a clamping seat 14 corresponding to the card slot 32. The connection seat 12 drives the clamping seat 14 to be inserted into the card slot 32. A wedge-shaped groove 18 is provided on the clamping seat 14, and a buckle 33 engaged with the wedge-shaped groove 18 is provided on the card slot 32. The connection between the electrode assembly 3 and the housing 1 is achieved by the engagement of the buckle 33 and the wedge-shaped groove 18.

[0034] Exemplarily, a ring groove 36 is provided near the head of the electrode head 39 on the sleeve 31. An annular brush ring 37 is provided within the ring groove 36. The brush ring 37 has brush ring contacts 38. The brush ring contacts 38 are in contact with the electrode head 39. When the electrode assembly 3 is removed from the housing 1 and appropriately moved a certain distance so that the head of the electrode head 39 enters the sleeve 31, the brush ring contacts 38 scrape off the blood scab attached to the surface of the electrode head 39. After scraping, the electrode assembly 3 is cleaned and disinfected. The contact between the brush ring 37 and the electrode head 39 can also play a limiting role on the electrode head 39 to prevent the electrode head 39 from shifting within the sleeve 31.

[0035] In the specific operation of the present invention, first, the electrode assembly 3 is docked and engaged with the connection seat 12 of the housing 1. Press the power-on key of the key module 2 to make the power module 5 conduct with the electrode assembly 3 and control the cooling module 7 to turn on. The required power can be selected through the power parameter adjustment key, and the signal is transmitted to the circuit board. The circuit board adjusts the magnitude of the output power according to the control signal. The output electrical signal is transmitted to the high-frequency generator, and the electrical signal is converted into high-frequency current to perform the electrocoagulation operation. The high-frequency current is transmitted to the target tissue area through the electrode head 39, so as to achieve the purpose of hemostasis in the eye. At the same time, the semiconductor refrigerating sheet of the cooling module 7 generates cold energy, so that the cold energy flows through the first cooling channel 82 and the second cooling channel 83 and is transmitted into the cooling medium circulation cavity 391. Then, the heat of the electrode head 39 is conducted to the surface of the heat-conducting fin 34 faster by the heat-conducting fin 34 and further conducted to the cooling inlet pipe 41 to improve the heat conduction efficiency. Finally, the cold energy is transported to the inside of the housing 1 by the cooling return pipe 42, so as to quickly cool down the electrode head 39 and each functional device inside the housing 1, enhance the overall cooling efficiency, and effectively avoid the phenomenon of "adhesive knife" of the electrode head 39.
