Description

Technical Field

[0001] This utility model relates to the field of medical tools, and in particular to an easy-to-operate interventional catheter sheath fixation assembly. Background Technology

[0002] A catheter sheath is a device used in medical procedures, primarily to provide access within blood vessels or body cavities. Catheter sheaths are typically made of flexible materials with good biocompatibility and mechanical strength, and need to be secured during use to facilitate manipulation by medical personnel.

[0003] According to the Chinese patent "A Catheter Sheath Fixation Device Authorization Announcement No. CN217510978U", this utility model catheter sheath fixation device is designed with a fixing seat and a positioning frame. In use, the doctor inserts the puncture head into the patient's body according to the selected position, then peels off the protective layer of the fixation plate, and the adhesive layer of the fixation plate is attached to the human body, thereby fixing the positioning frame.

[0004] Although the above-mentioned application can fix the catheter sheath to the fixation base and then fix the fixation base to the fixation plate to achieve the fixation of the catheter sheath, the device requires the fixation base and fixation plate to be installed before operation. Because the area of ​​the fixation plate is too large, it can easily obstruct the operation process of medical personnel and cause inconvenience to operation.

[0005] Therefore, an easy-to-use interventional catheter sheath fixation assembly is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an easy-to-operate interventional catheter sheath fixation component to solve the above-mentioned problems and improve the inconvenience of operation.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: an easy-to-operate interventional catheter sheath fixation assembly, comprising: a sheath body, a fixing block and a fixing hole, wherein the sheath body is installed on the inner wall of the fixing block, and the fixing block has a fixing hole on its surface.

[0008] A fixing mechanism includes a connecting block fixedly connected to the bottom end of a fixing block. A sliding plate is fixedly connected to the bottom end of the connecting block. Limiting rods are fixedly connected to the inner walls of both sides of the sliding plate. Rotating blocks are rotatably connected to the surfaces of the limiting rods. Sliding grooves are formed on opposite sides of the two rotating blocks. Sliding blocks are slidably connected to the inner walls of the sliding grooves. Movable rods are hinged to the inner walls of the sliding blocks. Springs are fixedly connected to the opposite ends of the two movable rods. A positioning block is fixedly connected between the two springs. A locking plate is slidably connected to the surface of the sliding plate. Locking grooves are formed on the inner walls of both sides of the locking plate. A sliding rod is fixedly connected to the surface of the movable rod. A moving block is fixedly connected to the end of the sliding rod away from the spring. The sliding rod is slidably connected to the inner wall of the sliding plate.

[0009] Preferably, the fixing block is cube-shaped with an opening on one side, and a fixing groove is provided in the middle of the fixing block. This makes the sheath tube more stably fixed.

[0010] Preferably, a fixing pad is fixedly connected to the bottom end of the card plate. The fixing pad is circular with a rectangular opening on its surface, and the fixing pad is adhesively attached. This is to avoid obstructing the puncture head from performing punctures.

[0011] Preferably, the card plate has a rectangular cross-section, a strip-shaped opening on the side of the card plate near the moving block, and a rectangular opening at the top of the card plate with a length equal to that of the connecting block. This allows the fixing block to fit snugly against the card plate.

[0012] Preferably, the positioning block is fixedly connected to a slot in the inner wall of the slide plate, and the movable rod is slidably connected to the inner wall of the slot, allowing the movable rod to move in a straight line.

[0013] Preferably, the two movable blocks have arc-shaped cross-sections and are arranged opposite each other. This facilitates the retraction of the movable blocks.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting the sliding plate at the bottom of the fixing block and the locking plate on the surface of the fixing pad to cooperate with each other, the fixing block and the fixing pad can be detached. This allows medical staff to operate the catheter sheath without obstructing their operation. When medical staff need to fix the catheter sheath, they only need to slide the locking plate on the fixing pad and the sliding plate on the fixing block to fix the catheter sheath. This makes it convenient for medical staff to operate while fixing the catheter sheath.

[0016] 2. By setting a moving block to drive the sliding rod to move, the rotating block will rotate, making it convenient for medical staff to disassemble the fixing block and fixing pad. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-5 As shown, an easy-to-operate interventional catheter sheath fixation assembly includes: a sheath body 100, a fixation block 200 and a fixation hole 210. The sheath body 100 is installed on the inner wall of the fixation block 200, and the fixation hole 210 is provided on the surface of the fixation block 200.

[0025] The fixing mechanism 400 includes a connecting block 410 fixedly connected to the bottom of the fixing block 200. A sliding plate 420 is fixedly connected to the bottom of the connecting block 410. Limiting rods 423 are fixedly connected to the inner walls of both sides of the sliding plate 420. Rotating blocks 421 are rotatably connected to the surface of the limiting rods 423. Slide grooves 424 are opened on opposite sides of the two rotating blocks 421. A slider 425 is slidably connected to the inner wall of the slide groove 424. A movable rod 426 is hinged to the inner wall of the slider 425. Springs 427 are fixedly connected to the opposite ends of the two movable rods 426. A positioning block 428 is fixedly connected between the two springs 427. A locking plate 430 is slidably connected to the surface of the sliding plate 420. Locking grooves 431 are opened on the inner walls of both sides of the locking plate 430. A sliding rod 429 is fixedly connected to the surface of the movable rod 426. A moving block 422 is fixedly connected to the end of the sliding rod 429 away from the spring 427. The sliding rod 429 is slidably connected to the inner wall of the sliding plate 420.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the cross-section of the card plate 430 is rectangular. A strip-shaped opening is provided on the side of the card plate 430 near the moving block 422. A rectangular opening with the same length as the connecting block 410 is provided at the top of the card plate 430. The positioning block 428 is fixedly connected to the strip groove opened in the inner wall of the slide plate 420. The movable rod 426 is slidably connected to the inner wall of the strip groove.

[0027] In this embodiment, the connection angle between the movable rod 426 and the slide rod 429 is 90 degrees. The slide rod 429 is installed in the groove inside the slide plate 420. When the spring 427 is in the initial state, the rotating block 421 is in a state of unfolding to both sides. The two slide rods 429 are located at the far ends of the two grooves. At the same time, the slider 425 is hinged to the movable rod 426 and the slider 425 is slidably connected to the slide groove 424 so that when the rotating block 421 unfolds to both sides, the movable rod 426 can be connected to it in a straight line.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the fixing block 200 is a cube with an opening on one side, and a fixing groove is formed in the middle of the fixing block 200. The two moving blocks 422 have arc-shaped cross-sections and are arranged opposite to each other. A vertical strip opening is formed on the adjacent side of the opening side of the fixing block 200, and a fixing hole 210 penetrates the surface of the fixing block 200. The fixing holes 210 are distributed in steps, with half being equal to one end of the sheath and half being smaller than one end of the sheath.

[0029] A fixing pad 300 is fixedly connected to the bottom of the card plate 430. The fixing pad 300 is circular and has a rectangular opening on its surface. The fixing pad 300 is adhesively attached. The bottom of the fixing pad 300 is adhesively designed so that it can adhere to the surface of the human body.

[0030] In use, the sheath is first placed on the inner wall of the fixing block 200, then the catheter is passed through the positioning hole and connected to the sheath, followed by puncture. After puncture, when the sheath needs to be fixed, the fixing block 200 is placed in the fixed position, and then the clamping plate 430 on the fixing pad 300 is aligned with the connecting block 410 and the sliding plate 420. The clamping plate 430 is slid towards the end closer to the moving block 422. In the initial state, the rotating block 421 is in a state of unfolding towards both sides of the slider 425 under the action of the spring 427. When the slider 425 slides into the clamping plate 430, the two rotating blocks 421 are squeezed by the clamping plate 430 on both sides, squeezing the spring 427 while rotating relative to each other, completing the retraction. When the end of the sliding plate 420 away from the moving block 422 is aligned with the inner wall of the clamping plate 430... When one end contacts, the slide plate 420 fully enters the inner wall of the clamping plate 430, and at the same time, the two rotating blocks 421 simultaneously fully enter the clamping plate 430. The pressure on both sides of the clamping plate 430 is removed, and under the action of the spring force of the spring 427, they unfold to both sides again. At the same time, the end of the rotating block 421 near the moving block 422 abuts against the slot 431. Then, the bottom protective layer of the fixing pad 300 is removed, and the fixing pad 300, the fixing block 200 and the sheath are fixed to the preset position to complete the fixation. When it is necessary to separate the fixing block 200 from the fixing pad 300, the moving block 422 is manually squeezed relative to each other. The moving block 422 drives the slide rod 429 and the movable rod 426 to move relative to each other while squeezing the spring 427, so that the rotating block 421 rotates relative to each other to complete the retraction. Then, the clamping plate 430 is pulled out to complete the disassembly and separation.

[0031] It should be noted that the spring 427 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs, and will not be elaborated here.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
