DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0020] Embodiment: A vascular clamp frame for vascular surgery, see Figure 1-4The vascular clamp 1 includes two hingedly connected left and right movable rods 11, and the two movable rods 11 are arranged in an X shape. One end of the movable rod 11 is connected to a clamping block 12, and the other end of the movable rod 11 is connected to a grip ring 13. The hingedly connected left and right movable rods 11 enable the vascular clamp 1 to be flexibly opened and closed during use. The two movable rods 11 are arranged in an X shape so that the vascular clamp 1 can provide more stable support when clamping a blood vessel, thereby ensuring the stability and flexibility of the vascular clamp 1 during surgery. The two clamping blocks 12 are close to each other on one side. A rubber block 7 is connected, which can provide a buffer when clamping, so as to prevent the clamping block 12 from directly contacting the blood vessel, thereby protecting the blood vessel, and increasing the friction between the blood vessel and the clamping block 12, so as to firmly clamp the blood vessel and enhance the stability of clamping. A rubber ring 8 is connected inside the grip ring 13, and the rubber ring 8 can increase the friction with the fingers to prevent slipping, so as to ensure that the doctor can stably hold the vascular clamp 1 for surgery. An arc-shaped rack 2 is connected to the side of the left movable rod 11 close to the grip ring 13, and the right movable rod 11 is connected to the left movable rod 11. A guide frame 3 that fits with the arc-shaped rack 2 is connected to one side of the upper grip ring 13, an inverted U-shaped slide bar 4 is slidably connected to the right movable rod 11, the inverted U-shaped slide bar 4 is located outside the guide frame 3, a clamping block 41 for clamping the arc-shaped rack 2 is connected to the side of the inverted U-shaped slide bar 4 close to the guide frame 3, the clamping block 41 is slidably connected to the guide frame 3 and extends into the guide frame 3, the side of the clamping block 41 facing the arc-shaped rack 2 is an inclined surface, a first spring 51 is connected between the inverted U-shaped slide bar 4 and the guide frame 3, and an end of the inverted U-shaped slide bar 4 away from the clamping block 41 is connected to the guide frame 3. A pressing block 5 is connected, a guide sleeve 6 is connected to the side of the right movable rod 11 away from the upper clamping block 12, an arcuate sliding rod 62 is connected to the side of the left movable rod 11 away from the upper clamping block 12, and the arcuate sliding rod 62 is slidably connected in the guide sleeve 6, a second spring 61 is connected between the arcuate sliding rod 62 and the guide sleeve 6, and a hanging ring 9 is connected to the outer wall of the left grip ring 13, through which the blood vessel clamp rack can be conveniently hung on an operating table, a surgical stand or other supporting equipment, so that the doctor can quickly take and place the blood vessel clamp rack during the operation.
[0021] Put your finger into the grip ring 13 and press the grip ring 13 to make the two grip rings 13 approach each other, so that the two movable rods 11 can drive the two clamping blocks 12 to approach each other to clamp the blood vessel, and the arc-shaped rack 2 and the guide frame 3 are close to each other, so that the arc-shaped rack 2 moves into the guide frame 3. When the arc-shaped rack 2 contacts the clamping block 41, the arc-shaped rack 2 continues to move and squeeze the inclined surface on the clamping block 41, so that the clamping block 41 moves away from the arc-shaped rack 2, and the inverted U-shaped slide bar 4 moves accordingly to compress the first spring 51. When the tooth gap on the arc-shaped rack 2 is aligned with the clamping block 41, the first spring 51 is reset. Down, the inverted U-shaped slide bar 4 moves to reset, so that the clamping block 41 moves toward the direction close to the arc-shaped rack 2, so as to be inserted into the tooth gap on the arc-shaped rack 2 to lock the arc-shaped rack 2, so that the movable rod 11 and the clamping block 12 can be locked, and there is no need for manual force on the grip ring 13 all the time, which is convenient for doctors to perform surgical operations and effectively relieve hand fatigue and soreness; and locking the clamping block 12 can ensure that the clamping block 12 maintains a stable position and strength during the operation, so that the doctor can focus on the surgical operation without worrying about the clamping block 12 being accidentally loosened or shifted. This stability helps to improve the accuracy, safety and efficiency of the operation. The force with which the clamping block 12 clamps the blood vessel can be adjusted by adjusting the length of the arc-shaped rack 2 moved into the guide frame 3, the two movable rods 11 approach each other and make the guide sleeve 6 slide on the arc-shaped slide bar 62, and the second spring 61 is compressed accordingly; when the two clamping blocks 12 are to be moved away from each other to release the blood vessel, the pressing block 5 is pressed to move the pressing block 5 toward the guide frame 3, so that the inverted U-shaped slide bar 4 drives the clamping block 41 to move out of the tooth gap on the arc-shaped rack 2 to release the lock on the arc-shaped rack 2, and under the resetting action of the second spring 61, the two movable rods 11 drive the two clamping blocks 12 to move away from each other to release the blood vessel.
[0022] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
