[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] Please refer to Figures 1 - 3, An epidural catheter clamping forceps for probing the eustachian tube, comprising a bracket 1. The upper surface of the bracket 1 is provided with anti-slip ridges 2. The upper surface of the bracket 1 is provided with a notch 3. A rotating rod 4 is rotatably arranged between the front and rear inner walls of the notch 3. A turntable 5 is fixedly connected to the outer surface of the rotating rod 4. A support rod 6 is fixedly inserted into the outer surface of the turntable 5. The other end of the support rod 6 is fixedly connected to a chuck 7. An arc-shaped groove 8 is provided on the lower surface of the chuck 7. A dial 9 is fixedly connected to the lower end of the outer surface of the turntable 5. A spring 10 is fixedly connected between the right surface of the dial 9 and the left surface of the bracket 1.
[0023] Specifically, through the cooperation among structures such as the bracket 1, the anti-slip ridges 2, the notch 3, the rotating rod 4, the turntable 5, the support rod 6, the chuck 7, the arc-shaped groove 8, the dial 9, and the spring 10, when using an epidural catheter to perform eustachian tube probing during the operation, the catheter can be stably clamped by the clamp forceps to prevent the catheter from falling off, ensuring the clamping force of the forceps without flattening the catheter, so as to ensure that medical staff can stably use the forceps to assist in pushing the catheter.
[0024] In this implementation scheme: The arc-shaped groove 8 and the anti-slip ridges 2 are arranged in correspondence, and the dial 9 and the bracket 1 are arranged in corresponding staggered manner.
[0025] Specifically, the arc-shaped groove 8 can effectively fit the surface of the catheter to expand the clamping area.
[0026] In this implementation scheme: The chuck 7 and the anti-slip ridges 2 are arranged in correspondence, and the turntable 5 and the notch 3 are arranged in correspondence.
[0027] Specifically, through the cooperation between the chuck 7 and the anti-slip ridges 2, the catheter can be stably clamped.
[0028] Working principle: When medical staff need to perform ear probing on a patient, place the outer side of the epidural catheter on the anti-slip edge 2 of the bracket 1. By simultaneously holding the two dial plates 9 and the bottom end of the bracket 1 and approaching each other to squeeze the spring 10. At the same time, the dial plate 9 rotates in the notch 3 with the rotating rod 4 as the reference through the turntable 5. The turntable 5 drives the chuck 7 on the support rod 6 to approach the top of the bracket 1. Then, by bringing the chuck 7 close to the catheter on the bracket 1, the arc-shaped groove 8 is fitted to the surface of the catheter. Through the relative acting force between the chuck 7 and the bracket 1, the catheter is stably fixed through the cooperation of the arc-shaped groove 8 and the anti-slip edge 2, effectively ensuring the stability of clamping the catheter. The elastic force of the spring 10 can generate a certain rebounding acting force between the bracket 1 and the dial plate 9, which is opposite to the gripping force of the medical staff, thereby reminding the staff of the critical point of the clamp clamping, ensuring the concentration of the medical staff's clamping attention, and ensuring that the catheter is stably sent into the middle ear of the ear for eustachian tube probing work. After use, take out the catheter from the ear, then loosen the dial plate 9 and the bracket 1. The elastic force of the spring 10 pushes the dial plate 9 and the bracket 1 away from each other, which can cooperate with the turntable 5 to separate the chuck 7 and the top of the bracket 1 from clamping the catheter, and then take out the catheter.
[0029] Embodiment 2
[0030] Please refer to Figure 1 , on the basis of Embodiment 1, the present utility model provides a technical solution:
[0031] In this embodiment: The lower surfaces of the bracket 1 and the dial plate 9 are both fixedly connected with collar rings 11, and an anti-slip pad 12 is fixedly arranged on the inner surface of the collar ring 11.
[0032] Specifically, through structures such as the collar rings 11 and the anti-slip pads 12, when medical staff use the clamp, they can relatively pinch the two collar rings 11 to approach and separate with their fingers, thereby driving the bracket 1 to perform clamping and releasing work, and ensuring the stable grasping of the collar rings 11 through the anti-slip pads 12.
[0033] Working principle: When medical staff use the clamp to hold the catheter, they can put the thumb into the collar ring 11 on the bracket 1 and the index finger into the collar ring 11 on the dial plate 9. By fitting the fingers to the anti-slip pads 12 on the inner wall of the collar ring 11, the bracket 1 and the dial plate 9 can be conveniently and stably linked, ensuring stable and labor-saving use.
[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
