Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and more specifically, to an electrode wire organization and fixation frame for cardiac surgery. Background Technology

[0002] Cardiac surgery is a crucial medical approach for treating heart and major blood vessel diseases. Through open-chest, thoracoscopic, or interventional procedures, it repairs, replaces, or reconstructs conditions such as congenital heart disease (e.g., ventricular septal defect, tetralogy of Fallot), coronary artery disease, valvular heart disease, and aortic aneurysms. For example, coronary artery bypass grafting restores blood supply to the heart muscle by transplanting a blood vessel around a narrowed coronary artery; heart valve replacement surgery uses an artificial valve to replace a diseased valve, improving heart function. With technological advancements, minimally invasive cardiac surgery and robot-assisted surgery are becoming increasingly common, achieving precise treatment with less trauma, significantly reducing surgical risks, shortening patient recovery time, and saving countless lives.

[0003] In cardiac surgery, devices such as pacemakers or defibrillators are connected to the heart via electrode leads. Current electrode lead organizers only provide cable management and support, resulting in low space utilization and ineffective protection of the leads. If the electrode leads between the patient and the device are long, they may dangle on the ground, increasing their risk of damage. Therefore, we propose an electrode lead organizer for cardiac surgery. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an electrode lead management and fixation frame for cardiac surgery, so as to solve the technical problems that the current equipment only has the functions of line management and support for electrode leads, with low space utilization and inconvenient and ineffective protection of electrode leads.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electrode lead handling and fixing frame for cardiac surgery, comprising a lead handling frame and a protective frame mounted on the lead handling frame. The lead handling frame includes a base, a second lead handling section, a first lead handling section, and an inlet section. The second lead handling section and the first lead handling section are located at both ends of the base. The inlet section is located at the end of the first lead handling section. Support legs are symmetrically arranged at the lower end of the inlet section. The protective frame includes a table panel, a bending section, and a first pressure section. The bending section is bent at 90 degrees and located at the end of the table panel. The first pressure section is bent at 90 degrees and located at the end of the bending section. A second pressure section and a telescopic rod are arranged at the lower end of the table panel.

[0006] Preferably, the angle between the second and first cable management sections and the base section is 80 degrees, the tail of the second cable management section is bent at 90 degrees, and the tail of the second cable management section is curved in an arc shape.

[0007] Preferably, the cable inlet section is arranged in a fan shape along the long axis, and the cable inlet section, the second cable management section and the first cable management section are each provided with a plurality of cable management grooves, and the cable management grooves of the cable inlet section are distributed radially.

[0008] Preferably, the cable management groove includes a limiting part and a receiving part. The receiving part is located at the lower end of the limiting part. The limiting part is a trapezoid that gradually increases in size from top to bottom, and the receiving part is semi-circular.

[0009] Preferably, both the upper ends of the tabletop and the first pressing part are provided with recessed portions. The shape of the first pressing part is consistent with the shape of the wire inlet. Two second pressing parts are symmetrically distributed at the lower end of the tabletop. The second pressing parts are distributed at an 80-degree angle to the tabletop. The outer surface of the second pressing part is provided with a pressing surface. The pressing surface is respectively attached to the second wire guiding part and the first wire guiding part. Positioning grooves are symmetrically provided on both sides of the second pressing part. The second pressing part is engaged with the second wire guiding part and the first wire guiding part through the positioning grooves.

[0010] Preferably, there are several telescopic rods arranged in a linear array along the horizontal direction and in a stepped staggered layout along the depth direction. Each telescopic rod consists of a rectangular sleeve rod and a rectangular solid rod. The rectangular solid rod is telescopically installed inside the rectangular sleeve rod. A tightening bolt is threaded onto the lower part of the outer surface of the rectangular sleeve rod. A pressure rod is provided at the lower end of the telescopic rod, and a pressure groove is provided at the lower end of the pressure rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a suture rack structure, features a unique suture rack structure where the second and first suture rack sections, together with the base, form a U-shape. The second suture rack section is 30 centimeters higher than the operating table, effectively shortening the length of the electrode leads from the first to the second suture rack section. This prevents the electrode leads from being dragged on the ground and trampled, and also prevents the end of the electrode lead connected to the patient from resting on the patient's body. The suture inlet is fan-shaped with radially distributed suture slots, facilitating the introduction of electrode leads from all directions and achieving efficient suture management. Furthermore, the protective frame's tabletop and the recessed portion at the upper end of the first suture pressing section form a placement platform, which can hold surgical instruments while protecting the electrode leads. This fully utilizes the operating room space, serving multiple functions simultaneously with suture management, avoiding wasted space in the cardiac surgery operating room. It solves the problem that current equipment only provides suture management and support, resulting in low space utilization and inconvenient and ineffective protection of the electrode leads.

[0013] 2. This utility model also features a protective frame structure. The first wire pressing part of the protective frame is identical in shape to the wire inlet part, fitting snugly against the wire inlet part to limit and support the electrode wires. The end of the table panel limits the electrode wires at the outlet of the wire management groove. The second wire pressing part fits snugly against the second and first wire management parts to limit the electrode wires on it, thus fully covering the electrode wires and providing excellent protection. At the same time, the telescopic rod drives the wire pressing rod to adjust the height, and multiple wire pressing rods can individually press different electrode wires to prevent the wires from dangling and tangling, further protecting the electrode wires.

[0014] 3. This utility model also features a telescopic rod structure. The telescopic rod consists of a rectangular sleeve rod and a rectangular solid rod. The telescopic rods, which are linearly distributed in the horizontal direction and staggered in the vertical direction, can be easily adjusted in length. The telescopic rod can be easily adjusted by loosening and tightening the top bolt, thereby flexibly adjusting the height of the pressure rod and adapting to the different requirements for fixing the electrode wires.

Detailed Implementation

[0022] like Figures 1 to 6As shown, this utility model relates to an electrode lead handling and fixing frame for cardiac surgery, including a lead handling frame 100 and a protective frame 200 mounted on the lead handling frame 100. The lead handling frame 100 includes a base portion 101, a second lead handling portion 102, a first lead handling portion 103, and an inlet portion 104. The second lead handling portion 102 and the first lead handling portion 103 are distributed at both ends of the base portion 101. The inlet portion 104 is located at the end of the first lead handling portion 103. Support legs 106 are symmetrically arranged at the lower end of the inlet portion 104. The protective frame 200 includes a table panel 201, a bending portion 202, and a first wire pressing portion 203. The bending portion 202 is bent at ninety degrees and located at the end of the table panel 201. The first wire pressing portion 203 is bent at ninety degrees and located at the end of the bending portion 202. A second wire pressing portion 205 and a telescopic rod 206 are arranged at the lower end of the table panel 201. This invention not only achieves efficient wire management, with its fan-shaped wire inlet and radial wire management grooves facilitating the introduction of wires from multiple directions, but also significantly improves space utilization. The protective frame protects the electrode wires while also providing space for surgical instruments, effectively solving the problems of low space utilization and insufficient protection performance of traditional equipment.

[0023] Specifically, the angle between the second suture guide 102 and the first suture guide 103 and the base 101 is 80 degrees. The tail of the second suture guide 102 is bent at 90 degrees, forming an arc. The height of the second suture guide 102 is 30 centimeters higher than the operating table. The second suture guide 102 and the first suture guide 103 form a U-shape with the base 101, which can support the protective frame 200. Furthermore, the certain height of the second suture guide 102 and the first suture guide 103 effectively shortens the length of the electrode wire from the first suture guide 103 to the second suture guide 102, preventing the electrode wire from being too long and resting on the ground, thus preventing the electrode wire from being stepped on. The height of the second suture guide 102, which is 30 centimeters higher than the operating table, can provide support between the electrode wire and the patient, preventing the end of the electrode wire connected to the patient from resting on the patient.

[0024] Furthermore, the cable inlet 104 is arranged in a fan shape along its long axis, and several cable management grooves 105 are provided on the cable inlet 104, the second cable management section 102, and the first cable management section 103. The cable management grooves 105 of the cable inlet 104 are distributed radially. The fan-shaped and radially distributed cable management grooves 105 of the cable inlet 104 can facilitate the introduction of electrode wires from the cable inlet 104 into the cable management grooves 105.

[0025] It is worth noting that the cable management groove 105 includes a limiting part and a receiving part. The receiving part is located at the lower end of the limiting part. The limiting part is trapezoidal in shape, gradually increasing in size from top to bottom, while the receiving part is semi-circular. The electrode wire is pressed into the cable management groove 105. The limiting part can limit the electrode wire and prevent it from automatically detaching from the cable management groove 105.

[0026] It is worth mentioning that both the upper end of the tabletop 201 and the first crimping part 203 are provided with a recessed part 204. The shape of the first crimping part 203 is consistent with the shape of the wire inlet part 104. Two second crimping parts 205 are symmetrically distributed at the lower end of the tabletop 201. The second crimping parts 205 are distributed at an 80-degree angle to the tabletop 201. The outer surface of the second crimping part 205 is provided with a crimping surface 2051. The crimping surface 2051 is respectively attached to the second wire management part 102 and the first wire management part 103. The two ends of the second crimping part 205 are symmetrically provided with positioning grooves 2052. The second crimping part 205 is engaged with the second wire management part 102 and the first wire management part 103 through the positioning grooves 2052. The shape of the first wire pressing part 203 is consistent with the shape of the wire inlet part 104, so that the first wire pressing part 203 can fit against the wire inlet part 104. This not only limits the electrode wire but also provides good support for the first wire pressing part 203. The end of the table panel 201 can press against the end bend of the second wire management part 102, thereby limiting the electrode wire at the outlet of the wire management groove 105. The angle of the second wire pressing part 205 can fit against the second wire management part 102 and the first wire management part 103, thereby limiting the electrode wire at the outlet of the second wire management groove 105. The electrode wires on part 103 are limited, which can cover the electrode wires in all directions and provide good protection for the electrode wires. Secondly, the protective frame 200 is supported on the suture rack 100. With the help of the positioning groove 2052, the protective frame 200 can be stably supported. With the help of the recessed part 204, the table panel 201 of the protective frame 200 and the upper end of the first suture pressing part 203 can form a placement platform, which can be used to place surgical instruments. This utility model makes full use of the operating room space and plays other roles while suture management, preventing the waste of space in the cardiac surgery operating room.

[0027] It is worth noting that there are several telescopic rods 206, which are arranged in a linear array along the horizontal direction and in a stepped staggered layout along the depth direction. Each telescopic rod 206 is composed of a rectangular sleeve rod and a rectangular solid rod. The rectangular solid rod is telescopically installed inside the rectangular sleeve rod. A tightening bolt is threaded at the lower part of the outer surface of the rectangular sleeve rod. A pressure rod 207 is provided at the lower end of the telescopic rod 206, and a pressure groove 2071 is provided at the lower end of the pressure rod 207. The telescopic rod 206 can adjust the height of the wire pressing rod 207. The wire pressing rod 207 can press the electrode wires between the second wire guiding section 102 and the first wire guiding section 103. Multiple wire pressing rods 207 can press different electrode wires individually to prevent the electrode wires from being suspended and thus tangling. The telescopic rods 206, which are linearly distributed in the horizontal direction and staggered in the vertical direction, can be easily adjusted in length. During adjustment, loosening the tightening bolt can stretch or retract the rectangular solid rod to adjust the height of the wire pressing rod 207. After adjustment, tighten the tightening bolt.

[0028] Working Principle: This embodiment provides an electrode lead management and fixation frame for cardiac surgery. In use, the lead frame 100 is first placed in a suitable position, with the tail of the second lead management section 102 facing the operating table and the lead inlet 104 facing the equipment. The base 101 provides stability, and the support legs 106 further stabilize the lead inlet 104. Then, electrode leads from various cardiac surgery devices are introduced along the fan-shaped and radially distributed lead management grooves 105 of the lead inlet 104. After the electrode leads enter the lead management grooves 105, the trapezoidal limiting part, which gradually increases in size from top to bottom, effectively restricts their position and prevents them from detaching automatically when pressed into place. The semi-circular receiving part... This provides a suitable placement space for the electrode leads. The electrode leads extend along the cable tray 105 of the first cable management section 103, enter the second cable management section 102, and exit from the tail end of the second cable management section 102. Because the second cable management section 102 and the first cable management section 103 form an 80-degree angle with the base section 101, and the tail end of the second cable management section 102 is curved at a 90-degree angle, with a height 30 centimeters higher than the operating table, the length of the electrode leads is effectively shortened during the process from the first cable management section 103 to the second cable management section 102, preventing them from being dragged on the ground and stepped on. It also provides support for the electrode leads connected to the patient. Then, the protective frame 200 is installed on the cable management frame 100, allowing the second cable to exit. The wire pressing part 205 is engaged with the second wire guiding part 102 and the first wire guiding part 103 via the positioning groove 2052. The wire pressing surface 2051 of the second wire pressing part 205 adheres to the second wire guiding part 102 and the first wire guiding part 103, limiting the electrode wires on the wire guiding part. The end of the platform 201 presses against the end bend of the second wire guiding part 102, limiting the electrode wires at the outlet of the wire guiding groove 105. The first wire pressing part 203, which has the same shape as the wire inlet part 104, adheres to the wire inlet part 104, not only limiting the electrode wires but also providing good support for the first wire pressing part 203. At the same time, the recessed part 204 at the upper end of the platform 201 and the first wire pressing part 203 constitute a placement platform. Surgical instruments can be placed there. If further fixation of electrode leads is required, the tightening bolts on the telescopic rod 206 can be loosened, the rectangular solid rod can be stretched or contracted, and the height of the pressure rod 207 can be adjusted so that it can press the electrode leads between the second wire management section 102 and the first wire management section 103 through the pressure groove 2071. Multiple telescopic rods 206 arranged in a horizontal linear array and staggered in a stepped layout in the depth direction can press different electrode leads separately to prevent the electrode leads from being suspended and tangled together. After adjustment, the tightening bolts are tightened to fix them. Through the above operations, the electrode leads in cardiac surgery can be organized, fixed and protected, while making reasonable use of the operating room space.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
