[0035] Embodiment 1
[0036] This embodiment provides a medical knot-tying training device that can be fixed on a desktop. Figure 1 As shown, in a preferred embodiment, the medical knotting training device includes a cross bar 20 made of a hard material extending along the length direction of the desktop 10, and a fixing seat 30 connected to both ends of the cross bar 20 for supporting the cross bar 20. The cross bar 20 can be made of hard plastic or metal. The fixing seat 30 extends along the width direction of the desktop 10, and the two ends of the fixing seat 30 have two clamping blocks that can be clamped on both sides of the width direction of the desktop 10 respectively. The cross bar 20 is suspended to facilitate the insertion of the knotting training rope. The knotting training rope is sleeved on the cross bar 20 at intervals for trainees to train; preferably, the outer wall of the cross bar 20 is provided with a plurality of grooves 21 for fixing the position of the knotting training rope, and the plurality of grooves 21 are spaced apart along the length direction of the cross bar 20.
[0037] When knotting training is needed, the fixing seat 30 clamps the two sides of the desktop 10 in the width direction through two clamping blocks to be clamped and fixed on the desktop 10. The two fixing seats 30 are clamped and fixed on the desktop 10 at intervals along the length direction of the desktop 10. The crossbar 20 is supported by the two fixing seats 30 and extends along the length direction of the desktop 10. The medical knotting training device in use is "H" shaped. When teaching knotting, multiple students are located on one side or both sides of the desktop 10, and the knotting training rope loop is set in the groove 21 of the crossbar 20 and fixed on the crossbar 20, and then practice knotting, such as single knot, square knot, etc. When the knotting training device is not in use, the knotting training device is removed from the desktop 10 by removing the two fixing seats 30.
[0038] In the present invention, one of the two blocks at both ends of the fixed seat 30 is a fixed block 31, and the other is a movable block 32. For example, the fixed block 31 is on the front side of the desktop 10, and the movable block 32 is on the back side of the desktop 10. The movable block 32 can slide along the length direction of the fixed seat 30 and be clamped and fixed on the outside of the desktop 10. For example, the back side of the fixed seat 30 has a slide groove 33 extending along its length direction, and a slide rod 34 is slidably connected in the slide groove 33. The movable block 32 is fixedly connected to the rear end of the slide rod 34. The slide rod 34 is elastically connected to the slide groove 33 through an elastic member 35 (columnar spring). The rear end of the elastic member 35 is fixedly connected to the front end of the slide rod 34, and the front end of the elastic member 35 is fixedly connected to the bottom of the slide groove 33.
[0039] When installing the fixing seat 30, the elastic force of the elastic member 35 is overcome, and the movable block 32 or the slide bar 34 is pulled so that the distance between the two blocks is greater than the width of the desktop 10, so that the two blocks are clamped on both sides of the desktop 10. The movable block 32 or the slide bar 34 is released, and under the action of the elastic member 35, the slide bar 34 retracts into the slide groove 33 to reduce the distance between the movable block 32 and the fixed block 31, so that the two blocks clamp both sides of the desktop 10, so as to clamp and fix the fixing seat 30 on the desktop 10.
[0040] Preferably, the inner sides of the fixed card block 31 and the movable card block 32 that are in contact with the desktop 10 are both provided with rubber pads, which are soft and non-slip, have a better clamping effect, and can prevent the hard buckle from scratching the side of the desktop 10.
[0041] It should be noted that the elastic member 35 may not be provided, and instead a locking member for locking the slide bar 34 may be connected to the fixed seat 30. The locking member is a locking bolt that can be tightly pressed against the outer wall of the slide bar 34. By loosening the locking member, the slide bar 34 can slide in the slide groove 33. The slide bar 34 can be slid along the length direction of the fixed seat 30 to adjust the distance between the movable block 32 and the fixed block 31. By tightening the locking member, the position of the movable block 32 can be fixed.
[0042] In another preferred embodiment, a storage cavity 36 for placing items is provided on the fixing seat 30. The storage cavity 36 can be used to place knotting training ropes and scissors. A cover is provided at the opening of the storage cavity 36 to prevent the items in the storage cavity 36 from scattering.
[0043] In another preferred embodiment, the two ends of the crossbar 20 are respectively detachably fixedly connected to the two fixing seats 30, such as by clamping or bolting; preferably, a strap 40 for fixing the two fixing seats 30 and the crossbar 20 together is connected to the fixing seats 30 or the crossbar 20. When the medical knot-tying training device is not in use, the crossbar 20 is removed from the two fixing seats 30, the crossbar 20 and the two fixing seats 30 are folded side by side, and then tied and fixed with the strap 40 for easy storage.
[0044] Further preferably, the crossbar 20 is a telescopic rod to reduce the overall length of the storage, and the length of the crossbar 20 can be adjusted according to the number of people. In this case, the two fixing seats 30 can be fixed on the desktop 10 first, and then the length of the crossbar 20 can be adjusted according to the distance between the two fixing seats 30, and then the two ends of the crossbar 20 are respectively connected to the two fixing seats 30.

[0047] When the medical knot-tying training device is not used, the two fixed seats 30 are rotated relative to the cross bar 20 through the first hinge seat 50 and the second hinge seat 60, and the cross bar 20 fits with the two fixed seats 30 to be folded. After folding, the medical knot-tying training device is in a long strip shape, which is tied and fixed by the strap 40 for easy storage. Preferably, the cross bar 20 is also a telescopic rod to reduce the overall length when folded.
[0048] In another preferred embodiment, the first articulated seat 50 is fixedly connected to the middle of the corresponding fixed seat 30, such as the fixed seat 30 on the left; the second articulated seat 60 is clamped to the middle of the corresponding fixed seat 30, and the second articulated seat 60 can slide along the length direction of the fixed seat 30, such as the left side of the fixed seat 30 on the right is provided with a strip groove, and the front end of the strip groove has a clamping groove located in the middle of the fixed seat 30. When the medical knotting training device is used, the second articulated seat 60 is clamped and fixed to the clamping groove. When the medical knotting training device is folded, as shown in FIG. Figure 3As shown, the second hinged seat 60 slides backward on the fixed seat 30 on the right side to shorten the overall length of the folded medical knot-tying training device for easy storage.
