Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a multi-needle rotary electrocoagulation hemostasis device. Background Art

[0002] In the field of modern medicine, especially in the escharotomy surgery for patients with extensive burns, effectively controlling bleeding is one of the key factors to ensure the success of the surgery. However, during the actual operation process, the bleeding from the wound surface often presents the characteristics of being extensive and difficult to control. Although the currently widely used needle-type electrocoagulation device can achieve the purpose of hemostasis to a certain extent, its working principle limits that it can only perform electrocoagulation treatment on a single bleeding point each time. This single-point hemostasis method is not only inefficient but also greatly prolongs the operation time, increases the risk of the patient during the operation, and the difficulty of postoperative recovery.

[0003] Specifically, traditional electrocoagulation devices usually consist of only one electrocoagulation needle, and electric energy needs to be applied to different bleeding points on the wound surface one by one to achieve the purpose of hemostasis. This method may be sufficient for small-area wounds or a small number of bleeding points, but it is inadequate when facing the extensive bleeding caused by extensive burns and escharotomy surgery. The surgeon has to repeatedly move and adjust the position of the electrocoagulation needle, which not only consumes a large amount of precious operation time but also may lead to incomplete hemostasis, affecting the operation effect and the patient's postoperative recovery.

[0004] In addition, long-term operation will also increase the physiological burden of the patient and the risk of complications such as infection. Therefore, how to develop a medical device that can quickly and efficiently achieve hemostasis for large-area wound surfaces has become an urgent problem to be solved in the current medical technology field.

[0005] In response to the above challenges, there is an urgent need for a new type of hemostasis device that should have the ability to handle multiple bleeding points simultaneously, thereby significantly improving the hemostasis speed and efficiency. The ideal solution should simplify the operation process, shorten the operation time, and reduce various risks brought by long-term operation, providing a safer and more effective hemostasis method for extensive burns and other surgeries with extensive bleeding. The present invention is proposed based on such a need, aiming to overcome the deficiencies of the existing technology through innovative design concepts and technical means, and meet the actual needs of clinical treatment. Summary of the Invention

[0006] The purpose of the present 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 extensive burns and escharotomy surgery in the existing technology. The many technical effects that can be produced by the preferred technical solutions among the many technical solutions provided by the present invention are described in detail below.

[0007] To achieve the above object, the present invention provides the following technical solutions: A multi-needle rotary electrocoagulation hemostasis instrument, comprising: a drum and a bracket, the drum is rotatably arranged on the bracket for rolling along the skin surface where hemostasis is required for the patient; An electrocoagulation mechanism, mounted on the drum, and comprising a plurality of electrocoagulation needles electrically connected to an external electrocoagulation instrument, these electrocoagulation needles are evenly arranged and fixed on the circumferential side wall of the drum; A roller, rotatably arranged on the bracket and parallel to the axis of the drum, located in front of the drum in the traveling direction during use, for rolling and clearing blood from the skin where hemostasis is required.

[0008] Further, the electrocoagulation mechanism further comprises a plurality of arc-shaped strips detachably connected to the drum, each arc-shaped strip is correspondingly inserted into a card slot opened in the circumferential direction of the drum, the electrocoagulation needles are correspondingly fixed on the arc-shaped strips, and a fixing component is provided between the arc-shaped strip and the drum.

[0009] Further, the fixing component includes an extension block and a wedge block, wherein a limiting groove matching therewith is provided on the side wall of the card slot of the drum, the extension block is fixed on the side wall of the arc-shaped strip, the large end of the wedge block is fixed at the end of the extension block, when the arc-shaped strip is inserted into the card slot, the wedge block and the extension block are sequentially inserted into the limiting groove to achieve interference fit.

[0010] Further, an iron sheet is installed at the bottom of the limiting groove, the extension block is made of a magnetic material, when the wedge block and the extension block are inserted into the limiting groove, the connection stability between the arc-shaped strip and the drum is enhanced by magnetic force.

[0011] Further, the diameter of the drum is 2 to 5 centimeters.

[0012] Further, the drum at least includes one sub-drum, each sub-drum is equipped with an independent electrocoagulation mechanism, and adjacent sub-drums can be spliced to extend the axial length.

[0013] Further, a protruding ring is provided at one end of each sub-drum, and a ring groove is opened at the other end. When adjacent two sub-drums are spliced, the protruding ring of one sub-drum is inserted into the ring groove of the other sub-drum to achieve fixation.

[0014] Further, a plurality of evenly distributed convex blocks are provided on the protruding ring, and an inner arc-shaped groove is provided at the end of the sub-drum. During splicing, the sub-drum is rotated to make the convex blocks completely enter the inner arc-shaped groove, thereby restricting axial movement.

[0015] Further, at least two groups of positioning components are installed on the bracket, each group includes 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 on the conical ring, and the conical plates are squeezed by tightening the positioning ring to fix the drum to prevent radial movement.

Compared with traditional single-needle or few-needle electrocoagulation devices, this design greatly improves the speed and efficiency of hemostasis, especially in the case of extensive bleeding caused by large-area burn escharotomy surgery.

[0018] Simplify the surgical procedure: Since the electrocoagulation needles can cover a large area of the wound surface at one time and automatically adjust the position through the continuous rolling of the drum, the need for doctors to manually adjust the position of the electrocoagulation needles is reduced. This not only simplifies the surgical operation process but also significantly shortens the surgical time, reduces the physiological burden and infection risk of patients.

[0019] Enhance the hemostasis effect: The roller designed in the present invention is located in front of the drum in the traveling direction and is used to roll and clear the blood on the skin that needs to be hemostatic. This pre-step helps to remove blood and other obstacles, enabling the electrocoagulation needles to directly contact the bleeding points, thereby improving the effectiveness and thoroughness of hemostasis.

[0020] Reduce the surgical risk: Reducing the surgical time and the time of patients' exposure to the surgical environment can effectively reduce the incidence of postoperative complications such as infection. In addition, due to the faster and more efficient hemostasis process, the recovery speed of patients will also be accelerated, further reducing the hospital stay and medical costs.

[0021] Strong adaptability: The instrument can flexibly adjust parameters such as the length, rotation speed, pressure, electrocoagulation intensity, and density of electrocoagulation needles of the drum according to the specific conditions of different patients to adapt to different wound sizes and bleeding degrees, and has strong clinical applicability and flexibility.

[0022] In summary, the multi-needle rotary electrocoagulation hemostasis instrument proposed by the present invention solves the problems of slow hemostasis speed and low efficiency in the prior art through its unique structural design and working principle, and provides a safe and effective solution for surgeries such as large-area burns and other surgeries with extensive bleeding.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following will further elaborate on the present application in conjunction with the attached Figure 1-6 This application embodiment discloses a multi-needle rotary electrocoagulation hemostasis instrument to further illustrate the present application in detail.

[0030] Referring to Figure 1 and Figure 2 As shown, the present invention provides a multi-needle rotary electrocoagulation hemostasis instrument, including a bracket 100, a drum 200, a roller 400, and an electrocoagulation mechanism 300.

[0031] The bracket 100 adopts an E-shaped design, and its three transverse rods are respectively used for the user to hold, mount the drum 200, and mount the roller 400. This structure not only ensures the stability and operability of the device, but also makes the axial directions of the drum 200 and the roller 400 parallel, ensuring the smoothness and consistency during the operation process. During use, the roller 400 is located in front of the drum 200. When using the hemostasis instrument to stop bleeding on the patient's skin, first, the roller 400 rolls over the patient's skin, and the position of the burn escharotomy is squeezed by the rolling of the roller 400 to push the tissue at the wound to be flat so as to squeeze the blood to other positions of the skin, thereby realizing the extrusion and removal of stasis and creating the best conditions for subsequent electrocoagulation treatment. Immediately afterwards, the drum 200 rolls along the same path to further achieve efficient hemostasis.

[0032] The electrocoagulation mechanism 300 is installed on the roller 200, and when the roller 200 rolls along the skin wound of the patient, electrocoagulation treatment can be carried out. This design greatly improves the hemostasis speed and efficiency, especially when dealing with extensive bleeding caused by large-area burn escharotomy surgery.

[0033] Referring to Figure 1 and Figure 2 As shown, two sets of positioning components are provided on the bracket 100, and each set of positioning components is respectively installed on the transverse rod of the bracket 100 corresponding to the roller 200 and the roller 400. This design ensures the precise alignment between components, thereby improving the operation accuracy of the entire instrument.

[0034] Each positioning component includes a positioning ring 120 and a tapered ring 110. The tapered ring 110 is formed by three arc-shaped pieces arranged circumferentially, where the tails of the arc-shaped pieces are fixedly connected to form a complete ring and sleeved on the bracket 100. The positioning ring 120 is sleeved outside the tapered ring 110 and connected to the tapered ring 110 by threads. When axial position limitation of the roller 200 or the roller 400 is required, first slide the tapered ring 110 to an appropriate position, and then rotate the positioning ring 120 to gradually approach the circular ring end of the tapered ring 110. Use the tightening force of the threads to squeeze the three arc-shaped pieces so that they tightly abut against the bracket 100 to achieve axial limit of the roller 200 or the roller 400.

[0035] An automatic self-aligning bearing 210 is configured inside the roller 200, and the bracket 100 supports the rotation of the roller 200 through this bearing 210 to ensure stability even when rolling on an uneven surface. Specifically, the design of the automatic self-aligning bearing 210 allows the roller 200 to automatically adjust its axis position when encountering an uneven ground or a slight inclination, thereby reducing vibrations and instability caused by surface unevenness. The smoothness of the operation of the roller 200 is improved.

[0036] Referring to Figure 3 and Figure 4 As shown, a convex structure 410 is provided at one end in the axial direction of the roller 400, and a corresponding groove 420 is configured at the other end in the axial direction of the roller 400. This unique design enables the extrusion area of the roller 400 in the axial direction to be increased by adjusting the position of the positioning component and increasing the number of rollers 400. Specifically, adjacent rollers 400 are tightly connected by precisely inserting the convex part 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 400 group be flexibly adjusted according to actual production requirements, but also good alignment and stable operation performance can be ensured between each roller 400.

[0037] Referring to Figure 3 and Figure 4 As shown, the diameter of the drum 200 in the present invention is set within 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 rate.

[0038] The drum 200 consists of at least one sub-drum 200. In practical applications, a single or multiple sub-drums 200 can be selected according to requirements. Two adjacent sub-drums 200 can extend their axial lengths through splicing, so as to flexibly adjust the overall length of the drum 200 to meet the needs of different working scenarios.

[0039] Referring to Figure 4 and Figure 5 As shown, at one end of each sub-drum 200 in its axial direction, there is a protruding ring 330, and at the other end, there is a corresponding ring groove 320. When splicing the sub-drums 200, the protruding ring 330 of one sub-drum 200 can be accurately inserted into the ring groove 320 of another sub-drum 200 to ensure their stable connection. In addition, a plurality of bumps 340 evenly distributed in the circumferential direction are fixedly connected to the protruding ring 330 of each sub-drum 200. At one end of the sub-drum 200 where the ring groove 320 is opened in the axial direction, there is also an inner arc groove 321, and one end of the inner arc groove 321 is connected to the ring groove 320 and extends into the interior of the sub-drum 200.

[0040] During the splicing process, the bumps 340 are inserted into the connection point of the inner arc groove 321 and the ring groove 320 provided in the axial direction of the sub-drum 200 together with the protruding ring 330, and the bumps 340 are rotated to be completely located in the inner arc groove 321. Finally, the bumps 340 abut against the side walls of the inner arc groove 321 at both ends of the sub-drum 200, effectively restricting the axial movement between the two spliced sub-drums 200.

[0041] This design not only enhances the positioning accuracy during the splicing process, but also improves the overall structural stability and reliability. Through this precise design, even in a high-intensity working environment, it can ensure the close cooperation between components and long-term stable operation, greatly reducing the maintenance frequency and cost.

[0042] Referring to Figure 3 and Figure 4As shown, each sub-drum 200 in the present invention is equipped with an independent electrocoagulation mechanism 300. This design ensures that an efficient and uniform electrocoagulation effect can be provided when dealing with multiple bleeding points. The electrocoagulation mechanism 300 includes a fixed component and a plurality of arc-shaped strips 360. A plurality of electrocoagulation needles 310 are installed on each arc-shaped strip 360. These electrocoagulation needles 310 are evenly distributed on the arc-shaped strip 360 and are electrically connected to an external electrocoagulation instrument to receive electrocoagulation energy.

[0043] To achieve precise treatment of bleeding points of different sizes and positions, the drum 200 is provided with card slots 350 at the circumferential side walls in its axial direction. The arc-shaped strips 360 are inserted into these card slots 350 to achieve stable fixation. The electrocoagulation needles 310 face outward and can contact the patient's skin during the rotation of the drum 200, enabling effective electrocoagulation treatment of multiple bleeding points simultaneously. In addition, according to specific requirements, the arc-shaped strips 360 without electrocoagulation needles 310 can be replaced, thereby flexibly adjusting the density of the electrocoagulation needles 310 to meet different clinical application requirements.

[0044] Refer to Figure 4 and Figure 6 As shown, the fixed component is composed 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 drum 200. Specifically, the side wall of the card slot 350 of the drum 200 is provided with a matching limit groove. The extension block 370 is fixed to the side wall of the arc-shaped strip 360, and the large 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 card slot 350, the wedge block 380 and the extension block 370 are sequentially inserted into the limit groove to form an interference fit, thus ensuring a tight connection between the two. An iron sheet 390 is installed at the bottom of the limit groove. The extension block 370 is made of a magnetic material. When the wedge block 380 and the extension block 370 are inserted into the limit groove, the connection strength between the arc-shaped strip 360 and the drum 200 is further enhanced by magnetic force.

[0045] Among them, the positive electrode of the electrocoagulation instrument is electrically connected to the arc-shaped strip 360, and the negative electrode of the electrocoagulation instrument is in direct contact with the human body, so that the electrocoagulation needles 310 on the arc-shaped strip 360 perform electrocoagulation hemostasis when contacting the patient's skin during use.

[0046] In a preferred embodiment of the present invention, the positive electrode of the electrocoagulation instrument passes through the bracket and is firmly and low-resistance electrically connected to the arc-shaped strip 360. The negative electrode is directly in contact with the human body through a soft and excellent conductive contact pad. During use, the electrocoagulation instrument will automatically adjust the output power according to preset parameters to achieve the best hemostasis effect without damaging the surrounding healthy tissues.

[0047] Among them, a sleeve 130 made of insulating material is also sleeved outside the drum 200, and its electrocoagulation needle 310 passes through the sleeve 130, so that the sleeve wraps the arc-shaped strip 360 inside the sleeve 130, so that only the electrocoagulation needle 310 carries electrocoagulation energy to contact the patient's skin when using this device.

[0048] Thus, the instrument can cover a large area of the wound surface at one time and automatically adjust the position through the continuous rolling of the drum 200, reducing the need for doctors to manually adjust the position of the electrocoagulation needle 310. This not only significantly shortens the operation time but also reduces the physiological burden on the patient.

[0049] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
