Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multi-needle rotary electrocoagulation hemostasis device. Background Technology

[0002] In modern medicine, especially in escharotomy for patients with extensive burns, effective bleeding control is a key factor in ensuring surgical success. However, in practice, wound bleeding often presents as widespread and difficult to control. While widely used needle electrocoagulation devices can achieve hemostasis to some extent, their working principle limits them to treating only a single bleeding point at a time. This single-point hemostasis method is not only inefficient but also significantly prolongs surgical time, increasing the risks to the patient during the procedure and the difficulty of postoperative recovery.

[0003] Specifically, traditional electrocoagulation devices typically consist of only one electrocoagulation needle, requiring the application of electrical energy to different bleeding points on the wound surface to achieve hemostasis. This method may be sufficient for small wounds or a few bleeding points, but it falls short when dealing with extensive bleeding caused by escharotomy for large burns. The surgeon must repeatedly move and adjust the position of the electrocoagulation needle, which not only wastes valuable surgical time but may also lead to incomplete hemostasis, affecting surgical outcomes and the patient's postoperative recovery.

[0004] Furthermore, prolonged surgical procedures increase the physiological burden on patients and raise the risk of complications such as infection. Therefore, developing a medical device that can quickly and efficiently achieve hemostasis over large wounds has become an urgent problem to be solved in the field of medical technology.

[0005] To address the aforementioned challenges, there is an urgent need for a novel hemostatic device capable of simultaneously managing multiple bleeding points, thereby significantly improving the speed and efficiency of hemostasis. The ideal solution should simplify surgical procedures, shorten surgical time, and reduce the various risks associated with prolonged surgery, providing a safer and more effective means of hemostasis for surgeries involving extensive burns and other conditions with widespread bleeding. This invention is based on this need, aiming to overcome the shortcomings of existing technologies and meet the practical needs of clinical treatment through innovative design concepts and technical means. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-needle rotary electrocoagulation hemostasis device to solve the technical problems of slow hemostasis speed and low efficiency in the face of extensive bleeding caused by escharotomy in large-area burns in the prior art. The various technical effects of the preferred technical solutions provided by this invention are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A multi-needle rotary electrocoagulation hemostasis device includes: a roller and a support, wherein the roller is rotatably mounted on the support for rolling along the skin surface of the patient where hemostasis is required;

[0009] An electrocoagulation mechanism is mounted on the drum and includes multiple electrocoagulation needles electrically connected to an external electrocoagulation instrument. These electrocoagulation needles are evenly arranged and fixed on the circumferential sidewall of the drum.

[0010] The roller is rotatably mounted on the support and parallel to the center line of the roller. When in use, it is located in front of the roller in the direction of travel and is used to roll and clean the skin that needs to stop bleeding.

[0011] Furthermore, the electrocoagulation mechanism also includes multiple arc-shaped strips detachably connected to the drum, each arc-shaped strip being inserted into a slot opened in the circumferential direction of the drum, the electrocoagulation needle being fixed on the arc-shaped strip, and a fixing component being provided between the arc-shaped strip and the drum.

[0012] Furthermore, the fixing component includes an extension block and a wedge block, wherein the groove sidewall of the roller is provided with a limiting groove that cooperates with it, the extension block is fixed to the sidewall of the arc strip, and the large end of the wedge block is fixed to the end of the extension block. When the arc strip is inserted into the groove, the wedge block and the extension block are inserted into the limiting groove in sequence to achieve an interference fit.

[0013] Furthermore, the bottom of the limiting groove is equipped with an iron sheet, and the extension block is made of magnetic material. When the wedge block and the extension block are inserted into the limiting groove, the connection stability between the arc strip and the roller is enhanced by magnetic force.

[0014] Furthermore, the diameter of the roller is 2 to 5 centimeters.

[0015] Furthermore, the roller includes at least one sub-roller, each sub-roller is equipped with an independent electrocoagulation mechanism, and adjacent sub-rollers can be spliced ​​together to extend their axial length.

[0016] Furthermore, each sub-roller has a protruding ring at one end and an annular groove at the other end. When two adjacent sub-rollers are spliced ​​together, the protruding ring of one sub-roller is inserted into the annular groove of the other sub-roller to achieve fixation.

[0017] Furthermore, the protruding ring is provided with a plurality of evenly distributed protrusions, and the end of the sub-roller is provided with an inner arc-shaped groove. During splicing, the sub-roller is rotated to make the protrusions completely enter the inner arc-shaped groove, thereby restricting axial movement.

[0018] Furthermore, the bracket is equipped with at least two sets of positioning components, each set including a positioning ring and a conical ring. The latter is sleeved on the bracket and consists of three arc-shaped plates. The positioning ring is screwed onto the conical ring. By tightening the positioning ring, the conical plates are squeezed to fix the roller and prevent axial movement.

[0019] Furthermore, the drum is internally equipped with an auto-aligning bearing, through which a bracket passes to support the drum's rotation.

[0020] The multi-needle rotary electrocoagulation hemostasis device of the present invention achieves the following technical effects through innovative design concepts and technical means:

[0021] Improved hemostasis efficiency: The design employs multiple electrocoagulation needles evenly arranged and fixed to the circumferential sidewall of the roller, allowing for simultaneous electrocoagulation of multiple bleeding points as the roller rolls along the skin surface. Compared to traditional single-needle or few-needle electrocoagulation devices, this design significantly improves the speed and efficiency of hemostasis, particularly in cases of extensive bleeding resulting from large-area burn escharotomy.

[0022] Simplified surgical procedure: Because the electrocautery needle can cover a large wound area at once, and its position is automatically adjusted by the continuous rolling of the roller, the need for doctors to manually adjust the position of the electrocautery needle is reduced. This not only simplifies the surgical procedure but also significantly shortens the operation time, reducing the patient's physiological burden and risk of infection.

[0023] Enhanced hemostasis: The rollers designed in this invention are located in front of the rollers in the direction of travel, and are used to roll and clean the skin requiring hemostasis. This pre-step helps to remove blood and other obstructions, allowing the electrocoagulation needle to contact the bleeding point more directly, thereby improving the effectiveness and thoroughness of hemostasis.

[0024] Reduced surgical risks: Reducing surgical time and the patient's exposure to the surgical environment effectively lowers the incidence of postoperative complications, such as infection. Furthermore, the faster and more efficient hemostasis process accelerates patient recovery, further reducing hospitalization time and medical costs.

[0025] Highly adaptable: This device can flexibly adjust parameters such as the length of the roller, rotation speed, pressure, electrocoagulation intensity, and density of the electrocoagulation needle according to the specific conditions of different patients, so as to adapt to different wound sizes and bleeding degrees, and has strong clinical applicability and flexibility.

[0026] In summary, the multi-needle rotary electrocoagulation hemostasis device proposed in this invention, through its unique structural design and working principle, solves the problems of slow hemostasis speed and low efficiency in existing technologies, providing a safe and effective solution for surgeries involving large-area burns and other conditions with extensive bleeding. This not only improves treatment outcomes but also brings a better prognosis to patients. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0036] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] The present application will be further described in detail below with reference to Figures 1-6. The embodiments of the present application disclose a multi-needle rotary electrocoagulation hemostasis device.

[0039] Referring to Figures 1 and 2, the present invention provides a multi-needle rotary electrocoagulation hemostasis device, including a support 100, a roller 200, a wheel 400, and an electrocoagulation mechanism 300.

[0040] The support 100 adopts an E-type design, with three horizontal bars for the user to hold, mount the roller 200, and mount the roller 400, respectively. This structure not only ensures the stability and ease of operation of the equipment but also ensures that the roller 200 and roller 400 are parallel in their axial directions, guaranteeing smoothness and consistency during operation. During use, the roller 400 is positioned in front of the roller 200. When using hemostatic instruments to stop bleeding on the patient's skin, the roller 400 first rolls over the patient's skin, pressing and squeezing the burn eschar area to flatten the tissue and force blood to other parts of the skin, thus clearing the blood clot and creating optimal conditions for subsequent electrocoagulation. Immediately afterwards, the roller 200 rolls along the same path, further achieving efficient hemostasis.

[0041] An electrocoagulation mechanism 300 is mounted on a roller 200, which performs electrocoagulation as it rolls along the patient's skin wound. This design greatly improves the speed and efficiency of hemostasis, especially in treating extensive bleeding caused by escharotomy in large-area burns.

[0042] Referring to Figures 1 and 2, the support 100 is equipped with two sets of positioning components, each set of positioning components being installed on the transverse rod of the support 100 corresponding to the roller 200 and the wheel 400, respectively. This design ensures precise alignment between the components, thereby improving the overall operational accuracy of the instrument.

[0043] Each positioning component includes a positioning ring 120 and a conical ring 110. The conical ring 110 is formed by three arc-shaped pieces arranged in a circumferential shape, with the tail ends of the arc-shaped pieces fixedly connected to each other to form a complete ring, which is fitted onto the bracket 100. The positioning ring 120 is fitted onto the outside of the conical ring 110 and connected to the conical ring 110 by threads. When it is necessary to limit the axial position of the roller 200 or roller 400, the conical ring 110 is first slidably adjusted to the appropriate position, and then the positioning ring 120 is rotated to gradually approach the annular end of the conical ring 110. The tightening force of the threads compresses the three arc-shaped pieces, making them tightly press against the bracket 100, thereby achieving axial positioning of the roller 200 or roller 400.

[0044] The roller 200 is internally equipped with an auto-aligning bearing 210, through which the bracket 100 supports the rotation of the roller 200, ensuring stability when rolling on uneven surfaces. Specifically, the design of the auto-aligning bearing 210 allows the roller 200 to automatically adjust its axial position when encountering uneven or slightly tilted surfaces, thereby reducing vibration and instability caused by surface unevenness. This improves the smoothness of the roller 200's operation.

[0045] Referring to Figures 3 and 4, one end of the roller 400 in the axial direction is provided with a protrusion 410, while the other end of the roller 400 in the axial direction is provided with a corresponding groove 420. This unique design allows for increasing the extrusion area of ​​the roller 400 in the axial direction by adjusting the position of the positioning components and increasing the number of rollers 400. Specifically, adjacent rollers 400 are tightly connected by precisely inserting the protrusion of one roller 400 into the groove 420 of another roller 400, thereby effectively expanding the overall extrusion contact surface. In this way, not only can the overall length and extrusion area of ​​the roller group 400 be flexibly adjusted according to actual production needs, but also good alignment and stable operating performance between the rollers 400 can be ensured.

[0046] Referring to Figures 3 and 4, the diameter of the roller 200 in this invention is set in the range of 2 to 5 cm, preferably 4 cm. This size design not only ensures sufficient strength and stability, but also takes into account the best balance between operational flexibility and material utilization.

[0047] The roller 200 consists of at least one sub-roller 200. In practical applications, one or more sub-rollers 200 can be selected according to requirements. Two adjacent sub-rollers 200 can be spliced ​​together to extend their axial length, thereby flexibly adjusting the overall length of the roller 200 to adapt to the needs of different working scenarios.

[0048] Referring to Figures 4 and 5, each sub-roller 200 has a protruding ring 330 at one end in the axial direction, and a corresponding annular groove 320 at the other end. When the sub-rollers 200 are spliced, the protruding ring 330 of one sub-roller 200 can be accurately inserted into the annular groove 320 of another sub-roller 200, ensuring a stable connection between the two. In addition, a plurality of circumferentially evenly distributed protrusions 340 are fixedly connected to the protruding ring 330 of each sub-roller 200. An inner arc-shaped groove 321 is also provided at the end of the sub-roller 200 where the annular groove 320 is formed in the axial direction. One end of the inner arc-shaped groove 321 is connected to the annular groove 320 and extends into the interior of the sub-roller 200.

[0049] During the splicing process, the protrusion 340 is inserted together with the protruding ring 330 into the connection point between the inner arc groove 321 and the ring groove 320 in the axial direction of the sub-roller 200. By rotating, the protrusion 340 is completely located in the inner arc groove 321, so that the protrusion 340 abuts against the side wall of the inner arc groove 321 at both ends of the sub-roller 200, effectively restricting the axial movement between the two spliced ​​sub-rollers 200.

[0050] This design not only enhances positioning accuracy during assembly but also improves the overall structural stability and reliability. This precise design ensures tight fit and long-term stable operation between components, even under high-intensity working conditions, significantly reducing maintenance frequency and costs.

[0051] Referring to Figures 3 and 4, each sub-roller 200 in this invention is equipped with an independent electrocoagulation mechanism 300. This design ensures efficient and uniform electrocoagulation when treating multiple bleeding points. The electrocoagulation mechanism 300 includes a fixing component and multiple arc-shaped bars 360, each arc-shaped bar 360 being equipped with multiple electrocoagulation needles 310. These electrocoagulation needles 310 are evenly distributed on the arc-shaped bars 360 and are electrically connected to an external electrocoagulation instrument to receive electrocoagulation energy.

[0052] To achieve precise treatment of bleeding points of different sizes and locations, the roller 200 has slots 350 on its circumferential sidewalls in the axial direction, and the arc-shaped strip 360 is inserted into these slots 350 for secure fixation. The electrocoagulation needle 310 faces outward and contacts the patient's skin during the rotation of the roller 200, allowing for effective electrocoagulation treatment of multiple bleeding points simultaneously. Furthermore, depending on specific needs, the arc-shaped strip 360 without the electrocoagulation needle 310 can be replaced, thereby flexibly adjusting the density of the electrocoagulation needle 310 to adapt to different clinical application requirements.

[0053] Referring to Figures 4 and 6, the fixing assembly consists of an extension block 370, a wedge block 380, and an iron sheet 390, ensuring a stable connection between the arc-shaped strip 360 and the roller 200. Specifically, the side wall of the slot 350 of the roller 200 is provided with a matching limiting groove. The extension block 370 is fixed to the side wall of the arc-shaped strip 360, while the larger end of the wedge block 380 is fixed to the end of the extension block 370. When the arc-shaped strip 360 is inserted into the slot 350, the wedge block 380 and the extension block 370 are sequentially inserted into the limiting groove, forming an interference fit, thereby ensuring a tight connection between the two. An iron sheet 390 is installed at the bottom of the limiting groove, and the extension block 370 is made of magnetic material. When the wedge block 380 and the extension block 370 are inserted into the limiting groove, the magnetic force further enhances the connection strength between the arc-shaped strip 360 and the roller 200.

[0054] The positive electrode of the electrocoagulation instrument is electrically connected to the arc-shaped bar 360, and the negative electrode of the electrocoagulation instrument is in direct contact with the human body. Thus, during use, the electrocoagulation needle 310 on the arc-shaped bar 360 performs electrocoagulation hemostasis when it comes into contact with the patient's skin.

[0055] In a preferred embodiment of the invention, the positive electrode of the electrocoagulation instrument passes through the support and achieves a stable and low-resistance electrical connection with the arc-shaped strip 360. The negative electrode directly contacts the human body through a soft and highly conductive contact pad. During use, the electrocoagulation instrument automatically adjusts its output power according to preset parameters to achieve optimal hemostasis without damaging surrounding healthy tissue.

[0056] The roller 200 is also covered with an insulating sleeve 130, through which the electrocoagulation needle 310 passes. The sleeve encloses the arc-shaped strip 360 inside the sleeve 130, so that when using this device, only the electrocoagulation needle 310 carries electrocoagulation energy and comes into contact with the patient's skin.

[0057] Therefore, this instrument can cover a large wound area in one operation, and its position is automatically adjusted by the continuous rolling of the roller 200, reducing the need for doctors to manually adjust the position of the electrocautery needle 310. This not only significantly shortens the operation time but also reduces the physiological burden on the patient.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
