Description

Technical Field

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

[0002] The basic principle of electrocoagulation hemostasis is to concentrate high-frequency current on the bleeding site, so that the temperature of this site rapidly rises to the degree that can denature proteins (usually 60 - 100 degrees Celsius), thereby closing the blood vessels and preventing further bleeding. This technology can not only effectively reduce the intraoperative blood loss, but also reduce the risk of postoperative complications, and help improve the clarity of the surgical field. Electrocoagulation hemostasis devices are often used in surgical operations. An electrocoagulation hemostasis device is a medical device used to heat tissues through high-frequency current during the operation to achieve the purpose of hemostasis. It is mainly applied in surgical operations, especially for small blood vessel bleeding situations that are difficult to control by traditional methods.

[0003] Currently, the electrocoagulation hemostasis devices on the market are mainly used to control local bleeding, and have certain limitations in the application of large-area hemostasis. For large-area bleeding, each bleeding point needs to be processed one by one, which requires a large amount of surgical time. And the bleeding speed of large-area bleeding is relatively fast and the blood loss is relatively large. If each bleeding point is processed one by one, it may cause excessive blood loss of the patient. Therefore, there is room for improvement and development in view of the above problems. Summary of the Invention

[0004] The present invention provides an electrode assembly and an electrocoagulation hemostasis device thereof, which can control bleeding more quickly and effectively, can process multiple bleeding points simultaneously in one operation, are applicable to large-area wounds or complex surgical scenarios that require rapid hemostasis, thereby shortening the surgical time and reducing the occurrence of complications. The specific implementation manners are as follows: An electrode assembly includes a support body, an electrode main body movably arranged on the support body, and a plurality of needle-shaped electrode needles arranged on the electrode main body. The electrode main body can displace relative to the central axis of the support body. The plurality of electrode needles have the same length, and adjacent electrode needles are insulated from each other. The electrode needles are in direct contact with the human tissue, so that the current is transmitted to the human tissue through the support body, the electrode main body, and the electrode needles in sequence.

[0005] As a further scheme of the present invention, the distances between the plurality of electrode needles are set to be the same.

[0006] As a further scheme of the present invention, the distance between adjacent electrode needles is set to be 2 - 5 mm.

[0007] As a further solution of the present invention, a sphere is provided on the electrode body, and the support body is provided with a spherical socket corresponding to the sphere. The sphere is movably arranged in the spherical socket, so that the electrode body drives the electrode needle to rotate around the central axis of the support body.

[0008] As a further solution of the present invention, the support body is cylindrical, and an insulating member is provided on the support body. The insulating member is axially sleeved on the support body.

[0009] In addition, the present invention also provides an electrocoagulation hemostasis device, which includes an electrode assembly and a main body for generating high-frequency current. The electrode assembly is connected to the positive output terminal of the main body; An insulating sleeve, inside which there is a cable, is electrically connected to the main body and the support body respectively, and is used to transmit the high-frequency current generated by the main body to the electrode assembly; A negative electrode, which contacts the human tissue, and the negative electrode is connected to the negative output terminal of the main body; As a further solution of the present invention, a compression hemostasis member is connected to the human body through a fixing band. The compression hemostasis member is detachably connected to the fixing band. The compression hemostasis member is provided with a plurality of through holes, which correspond to the electrode needles one by one, so that the electrode needles act on the human tissue through the through holes.

[0010] As a further solution of the present invention, a plurality of compression hemostasis members are provided, and adjacent compression hemostasis members are connected through a connection structure and can rotate relative to each other.

[0011] As a further solution of the present invention, the connection structure is detachably arranged on the compression hemostasis member. Card slots are provided at the four corners of the compression hemostasis member. The connection structure includes an elastic buckle, and the connection between the connection structure and the compression hemostasis member is realized by elastic clamping of the elastic buckle and the card slot.

[0012] As a further solution of the present invention, the connection structure includes an elastic engaging member and a connection seat engaged with the engaging member. The engaging member has an engaging groove and a channel. The connection seat is provided with a transfer shaft corresponding to the engaging groove. The channel is smaller than the diameter of the transfer shaft. When adjacent compression hemostasis members are connected, the transfer shaft enters from the channel and elastically snaps into the engaging groove, so that the transfer shaft is limited in the engaging groove.

[0013] As a further solution of the present invention, a locking member is provided on the engaging member. The locking member has a stop surface. The transfer shaft presses the locking member and elastically snaps into the engaging groove. The locking member resets so that the stop surface abuts against the transfer shaft, so that the transfer shaft is limited in the engaging groove.

Detailed implementation manner

[0017] The following describes the specific implementation manner of the present invention in conjunction with the accompanying drawings and embodiments: It should be noted that the structures, ratios, sizes, etc. illustrated in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present invention. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope that the technical content disclosed by the present invention can cover.

[0018] At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of clear narration, and are not used to limit the scope that the present invention can be implemented. The change or adjustment of their relative relationship, without substantial change of the technical content, should also be regarded as the scope that the present invention can be implemented.

[0019] Example 1, in combination with Figures 1 to 3 As shown, this embodiment provides an electrode assembly, including a support body, an electrode main body 1 movably arranged on the support body, and a plurality of needle-shaped electrode needles 2 arranged on the electrode main body 1. The electrode main body 1 can displace relative to the central axis of the support body. The plurality of electrode needles 2 have the same length, and adjacent electrode needles 2 are insulated from each other. The electrode needles 2 are in direct contact with the human tissue, so that the current is sequentially transmitted through the support body, the electrode main body 1, and the electrode needles 2 to the human tissue.

[0020] Exemplarily, in combination with Figure 3 As shown, the electrode main body 1 is a rectangular structure. The electrode needles 2 are arranged on the fitting surface of the electrode main body 1. The needle tips of the electrode needles 2 extend in the opposite direction of the fitting surface. The needle tips of the electrode needles 2 are in direct contact with the human tissue and serve as a conduction medium for the current, introducing the generated high-frequency current into the human tissue area to be processed. Through the thermal effect of the current, the blood in the blood vessel is coagulated, thereby achieving the purpose of hemostasis.

[0021] Specifically, the spacing between multiple electrode needles 2 is set to be the same. Setting the same spacing allows the electrode needles 2 to be evenly distributed and arranged on the electrode body 1, ensuring that when treating a larger area or a longer incision, energy can be applied to the target tissue more evenly, avoiding excessive damage caused by overly concentrated energy in local areas, and thus contributing to a more uniform current distribution. The number of electrode needles 2 can be selected according to actual applications.

[0022] Specifically, the spacing between adjacent electrode needles 2 is set to be 2 - 5 mm. Preferably, the spacing between adjacent electrode needles 2 is set to be 2.5 mm, which can ensure there is enough space for the current to pass through the electrode needles 2 and act effectively on the target tissue, without being too large to affect the synergistic effect in the adjacent area, enabling medical staff to more precisely control the electrocoagulation process and reducing the impact on surrounding healthy tissues.

[0023] Specifically, in combination Figure 2 As shown, to enable the electrode body 1 to displace around the central axis of the support body, a sphere 31 is provided on the electrode body 1, and the support body is provided with a spherical socket 51 corresponding to the sphere 31. The sphere 31 is movably arranged in the spherical socket 51, such that the electrode body 1 drives the electrode needles 2 to rotate around the central axis of the support body. Both the support body and the electrode body 1 are made of metal materials, and copper, gold, aluminum, etc. can be selected to conduct current. The support body and the electrode body 1 are connected by a spherical hinge, which allows the electrode body 1 to rotate in multiple directions, so that the electrode body 1 connected to the sphere 31 can drive the electrode needles 2 to rotate omnidirectionally around the center of the sphere 31 of the sphere 31, thereby realizing the angle adjustment of the electrode needles 2 and improving the usability of the electrode assembly.

[0024] Exemplarily, the support body is cylindrical, and an insulating member is provided on the support body. The insulating member is axially sleeved on the support body. The support body includes a conductive rod 3 connected to the electrode body 1 and a handle 5 movably connected to the conductive rod 3. The spherical socket 51 is opened on the handle 5, and the sphere 31 is correspondingly arranged on the conductive rod 3 relative to the spherical socket 51, such that the bottom end of the conductive rod 3 can displace around the central axis of the handle 5, thereby realizing that the electrode body 1 drives the electrode needles 2 to rotate omnidirectionally around the center of the sphere 31 of the sphere 31, and further realizing the angle adjustment of the electrode needles 2, which is applicable to electrocoagulation hemostasis surgeries that require various angle adjustments.

[0025] In this embodiment, insulating members are sleeved on the outer walls of the conductive rod 3 and the handle 5. The insulating members are insulating protection materials, such as polyvinyl chloride (PVC). During the electrocoagulation operation, the energized handle 5 can generate heat at the contact part with the conductive rod 3, and the insulating protection materials provided on the conductive rod 3 and the handle 5 can play an electrical insulation role, avoiding current shunting caused by the energized support body contacting other parts during the surgery and affecting the wound treatment efficiency.

[0026] Example 2, in combination with Figure 1 As shown, this embodiment provides an electrocoagulation hemostasis device, which includes the electrode assembly described in the above-mentioned Embodiment 1, and further includes a main body 7 for generating high-frequency current, and the electrode assembly is connected to the positive output terminal of the main body 7; an insulating sleeve 6 with a cable inside, which is electrically connected to the main body 7 and the support respectively, for transmitting the high-frequency current generated by the main body 7 to the electrode assembly; a negative electrode in contact with human tissue, and the negative electrode is connected to the negative output terminal of the main body 7; a compression hemostasis member 4 connected to the human body through a fixing band 45, and the compression hemostasis member 4 is detachably connected to the fixing band 45. The compression hemostasis member 4 is provided with a plurality of through holes 43, and the through holes 43 correspond to the electrode needles 2 one by one, so that the electrode needles 2 act on the human tissue through the through holes 43.

[0027] Exemplarily, the main body 7 internally includes a power supply module, a high-frequency signal generator, a control circuit board, a power amplifier, a feedback system, a protection circuit, etc. The power supply module provides stable working voltage and current for the entire device. The high-frequency signal generator is responsible for generating high-frequency current. Using radio frequency (RF) technology, the frequency range is generally between 300 kHz and 1 MHz, which helps to reduce damage to surrounding tissues and achieve effective electrocoagulation effect. The control circuit board includes components such as a microprocessor or a single-chip microcomputer, which are used to control and adjust the output power, working mode, and respond to user input (such as a foot switch). The power amplifier is used to enhance the signal strength generated by the high-frequency signal generator, so as to provide sufficient energy for the electrode needles 2 to perform electrocoagulation operations. The feedback system is used to monitor output parameters (such as current, voltage, power, etc.) in real time. The protection circuit is designed with various protection mechanisms, such as overload protection, short-circuit protection, temperature protection, etc., to ensure the safety of the operator and the reliability of the device itself. The connection interface is used to connect the support, the negative electrode, the foot switch, and other external devices to ensure the safety and efficiency of signal and power transmission. The insulating sleeve 6 connected between the connection interface and the support is provided with insulating protection materials, which are the same insulating protection materials as the above-mentioned insulating parts, and play an electrical insulation and protection role for the cable.

[0028] Exemplarily, the pipe end of the insulating sleeve 6 is provided with an elastic snap joint 61, and the handle 5 is provided with an insertion port 52 corresponding to the elastic snap joint 61. The elastic snap joint 61 and the insertion port 52 are snap-fitted to realize the connection between the insulating sleeve 6 and the handle 5. The connecting part between the elastic snap joint 61 and the handle 5 is made of metal material, so that the cable in the insulating sleeve 6 conducts current to the handle 5.

[0029] In this embodiment, the compression hemostasis member 4 can be made of hard medical plastic. The medical plastic has insulation properties, which can avoid the risk of electric shock to patients or medical staff during the use of the compression hemostasis member 4, and can also ensure the normal operation of the device and is not affected by external electricity.

[0030] Specifically, in combination with Figure 4 As shown, the compression hemostasis component 4 includes a hemostasis plate 41. The hemostasis plate 41 is fixed on the human body through a fixing band 45. Connecting holes 44 are provided at the edges adjacent to the four sides of the hemostasis plate 41. The connecting holes 44 penetrate through the top surface and the bottom surface of the hemostasis plate 41. Magic tapes are provided at both the head end and the tail end of the fixing band 45. In specific applications, the head end of the fixing band 45 passes through the connecting hole 44 and is bonded through the magic tape to be fixed on the hemostasis plate 41. After the tail end of the fixing band 45 bypasses the human body, it passes through the connecting hole 44 and is bonded through the magic tape, thereby fixing the hemostasis plate 41 on the human body. For multiple connected hemostasis plates 41, the fixing bands 45 of the hemostasis plates 41 can be detached, and the multiple hemostasis plates 41 are connected through a connecting structure. Then, a fixing band 45 with a suitable length is selected to fix the hemostasis plates 41 at the four corners, thereby realizing the compression hemostasis function for large-area wounds.

[0031] In this embodiment, in combination with Figure 4 As shown, for large-area wounds, multiple hemostasis plates 41 need to be connected to ensure complete coverage of the wound surface. Adjacent compression hemostasis components 4 are connected through a connecting structure and can rotate relative to each other.

[0032] Specifically, in combination with Figure 5 、 Figure 6 As shown, the connecting structure is detachably arranged on the compression hemostasis component 4. The used compression hemostasis component 4 and the connecting structure can be disinfected separately to ensure the safety of use. Card slots 47 are provided at the four corners of the compression hemostasis component 4. The connecting structure includes an elastic buckle 461. The connection between the connecting structure and the compression hemostasis component 4 is realized through elastic clamping of the elastic buckle 461 and the card slot 47. The shape of the elastic buckle 461 matches that of the card slot 47. An incision is provided on the elastic buckle 461. When the elastic buckle 461 is inserted into the card slot 47, the elastic buckle 461 abuts against the inner wall of the card slot 47, causing the incision to gradually shrink. When inserted to the bottom of the card slot 47, the elastic buckle 461 restores its elasticity and abuts against the inner wall of the card slot 47.

[0033] In this embodiment, in combination with Figure 7 As shown, a pressure spring 467 is provided at the position corresponding to the incision on the card slot 47. The pressure spring 467 can use its own elasticity to more stably abut the elastic buckle 461 against the inner wall of the card slot 47.

[0034] Specifically, in combination with Figures 5 to 7As shown, the connection structure includes an elastic engaging member 46 and a connection seat 48 engaged with the engaging member 46. The engaging member 46 has an engaging groove and a channel. The connection seat 48 is provided with a transfer shaft 481 corresponding to the engaging groove. The channel is smaller than the diameter of the transfer shaft 481. When adjacent pressure hemostasis members 4 are connected, the transfer shaft 481 enters through the channel and elastically snaps into the engaging groove, so that the transfer shaft 481 is limited in the engaging groove. The engaging groove is set as a plugging hole 462 that matches the transfer shaft 481. The channel is composed of an elastic snap groove 464 and an elastic plugging groove 463 and is elastic. The elastic plugging groove 463 communicates with the plugging hole 462. The distance between the opposite groove walls of the elastic snap groove 464 is the same as the diameter of the transfer shaft 481, and the distance between the opposite groove walls of the elastic plugging groove 463 is smaller than the diameter of the transfer shaft 481. When adjacent pressure hemostasis members 4 are connected, the transfer shaft 481 sequentially enters the plugging hole 462 through the elastic snap groove 464 and the elastic plugging groove 463. Since the distance between the opposite groove walls of the elastic plugging groove 463 is smaller than the diameter of the transfer shaft 481, a stop is formed between the elastic plugging groove 463 and the plugging hole 462, thereby limiting the transfer shaft 481 in the plugging hole 462. The engaging member 46 can rotate around the axis of the transfer shaft 481, so that adjacent pressure hemostasis members 4 can rotate relative to each other, thereby making multiple spliced pressure hemostasis members 4 fit the human body better.

[0035] In this embodiment, a pre-cut chamfer 465 for guiding the clamping of the transfer shaft 481 is provided at the opening of the elastic snap groove 464; a limiting ring 482 is axially provided on the transfer shaft 481. In the state where the engaging member 46 and the connection seat 48 are engaged, the limiting ring 482 abuts against the engaging member 46, so that the engaging member 46 is limited on the connection seat 48, thereby making the connection of adjacent pressure hemostasis members 4 more stable.

[0036] Exemplarily, in combination with Figure 7As shown, a locking member 42 is provided on the engaging member 46. The locking member 42 has a stop surface. The transfer shaft 481 presses the locking member 42 and elastically snaps into the engaging groove. The locking member 42 resets so that the stop surface abuts against the transfer shaft 481, limiting the transfer shaft 481 in the engaging groove. The locking member 42 is arranged at the position of the elastic insertion groove 463. The locking member 42 includes a stop member 421 in a trapezoidal shape, a return spring 424, and a linkage rod 425 connected to the stop member 421. A groove 466 is formed on the elastic insertion groove 463. The groove 466 includes a large-diameter groove cooperating with the return spring 424 and a small-diameter groove slidably connected to the linkage rod 425. The two ends of the return spring 424 are respectively connected to the large-diameter groove and the stop member 421. The stop member 421 has an abutting surface 423 and a guiding surface 422 arranged obliquely. When the transfer shaft 481 passes through the engaging member 46, the transfer shaft 481 drives the guiding surface 422 to compress the return spring 424 downward, enabling the transfer shaft 481 to pass through the elastic insertion groove 463. After the transfer shaft 481 enters the insertion hole 462, the return spring 424 restores its elastic force and drives the stop member 421 to reset. The abutting surface 423 abuts against the transfer shaft 481, limiting the transfer shaft 481 in the insertion hole 462, thereby making the connection between the engaging member 46 and the connecting seat 48 more stable.

[0037] In this embodiment, to detach the connecting seat 48 from the engaging member 46, the linkage rod 425 is set in a U-shaped structure and connected to two oppositely arranged stop members 421. When detachment is required, the linkage rod 425 is pulled downward. The linkage rod 425 drives the stop member 421 to move downward into the groove 466, enabling the transfer shaft 481 to pass through the elastic insertion groove 463, thus realizing the detachment function of the connecting seat 48 and the engaging member 46.

[0038] During specific surgical operations, an appropriate number of compression hemostasis components 4 are selected according to the size of the patient's injured wound surface, so that the compression hemostasis components 4 can cover the tissue area to be treated for pre-hemostasis treatment of the wound surface. Secondly, the negative electrode is connected to the human body, and the main unit 7 is turned on. The main unit 7 is set with appropriate parameters, thus completing the preparation work.

[0039] When in use, the doctor picks up the handle 5, penetrates the electrode needle 2 through the through hole 43 to contact the tissue and perform electrocoagulation treatment on it, and steps on the foot pedal switch to activate the current. At this time, it is possible to judge whether the expected electrocoagulation effect is achieved by observing the tissue reaction around the electrode needle 2. Release the foot pedal switch to stop the current supply. Multiple electrode needles 2 can perform electrocoagulation hemostasis on multiple hemostasis points, significantly improving the hemostasis efficiency and effectively avoiding excessive blood loss of the patient.
