Description

Technical Field

[0001] The utility model relates to the technical field of medical device equipment, and more specifically, to a hemostatic device for emergency digestive medicine. Background Technique

[0002] A hemostatic clip is a common hemostatic device for emergency digestive medicine. The hemostatic clip can clamp the bleeding blood vessel to prevent bleeding, and can maintain the clamping state of the blood vessel during the operation, making the operation safer and more convenient.

[0003] Chinese Patent Authorization Publication No.: CN220477628U provides a blood vessel hemostatic clip. This solution realizes rapid lateral movement by setting an activity sleeve. Through the contact between the inner diameter of the activity sleeve and the outer side of the clip arm, the V-shaped clip arms move closer to the middle. The operation is convenient, fast, and time-saving. Cooperating with the locking component, through the contact between the inclined plate and the tooth groove, it effectively prevents the activity sleeve from sliding backward, making the activity sleeve more stable after clamping. By lifting the L-shaped plate, driving the inclined plate to lift upward, the activity sleeve moves backward to release the clamping of the blood vessel, which is convenient and fast, and reduces the operation time during the operation.

[0004] During the operation, if it is found that the clamped blood vessel bleeds again, medical staff may need to readjust the position or clamping force of the hemostatic clip to ensure the smooth progress of the operation. However, in this solution, medical staff lack a strong hand support point when sliding the activity sleeve, and the clip arm may shake violently during the sliding process, thereby damaging the blood vessel trauma of the patient. Moreover, in this solution, medical staff must use both hands to slide the activity sleeve, which may cause inconvenience during the operation. Therefore, a hemostatic device for emergency digestive medicine is proposed for the above problems. Content of the Utility Model

[0026] Embodiment:

[0027] Please refer to Figures 1-3 , a hemostatic device for emergency gastroenterology, including a handle 1. One end of the handle 1 is integrally formed with a pair of symmetrically arranged clamping arms 2, and tooth grooves 3 are provided at both ends of the handle 1. An activity sleeve 4 is slidably connected to the outer end of the handle 1, and a handle 5 is fixedly connected to the end of the handle 1 away from the clamping arm 2. A pair of symmetrically arranged rotating rods 6 are rotatably connected to the outer end of the activity sleeve 4. One ends of the pair of rotating rods 6 close to each other extend to the inner side of the activity sleeve 4 and are fixedly connected with teeth 9 matching the tooth grooves 3.

[0028] Both pairs of teeth 9 are engaged with the tooth grooves 3 to fix the position of the activity sleeve 4. Restricted by the teeth 9, the user cannot slide the activity sleeve 4. When the user needs to slide the activity sleeve 4, place the palm against the handle 5, and then rotate the rotating rods 6 towards the handle 5 with the index finger and middle finger respectively, so that the rotating rods 6 drive the teeth 9 to rotate, and then the teeth 9 disengage from the tooth grooves 3. After the teeth 9 disengage from the tooth grooves 3, the user can directly pull the activity sleeve 4 to slide it on the outer end of the handle 1.

[0029] The pair of clamp arms 2 are both elastic. When the movable sleeve 4 moves toward the direction of the clamp arms 2, the pair of clamp arms 2 will be squeezed, so that the pair of clamp arms 2 are closed. When the movable sleeve 4 moves in the direction away from the clamp arms 2, the pair of clamp arms 2 will be reset under the action of elasticity, so that the clamping force of the pair of clamp arms 2 can be adjusted by sliding the movable sleeve 4. During the adjustment process, the user can operate it with one hand, which brings convenience to use. The handle 5 can serve as a strong support point for the user's hand, so that in the process of moving the movable sleeve 4, the shaking of the pair of clamp arms 2 can be greatly reduced, avoiding damage to the patient's vascular trauma.

[0030] The pair of clamp arms 2 are both arranged in an arc shape, and the tooth groove 3 extends from the surface of the handle 1 to the surface of the clamp arm 2 .

[0031] The arc-shaped clamping arm 2 can better adapt to the shape of the blood vessel, improve the stability of the blood vessel clamping during the hemostasis process, and will not cause severe compression to the blood vessel.

[0032] A spring 7 is provided between the handle 5 and the movable sleeve 4. The spring 7 is sleeved on the outer end of the handle 1. Both ends of the spring 7 are fixedly connected to the movable sleeve 4 and the handle 5 respectively. The spring 7 is in an expanded state and has compression capability.

[0033] In this solution, the spring 7 is in an expanded state, which means that in the initial state, it squeezes a pair of clamp arms 2, so that the pair of clamp arms 2 are in a clamped state. When the user pulls the movable sleeve 4 toward the handle 5, the movable sleeve 4 will squeeze the spring 7. When the user appropriately reduces the force of pulling the rotating rod 6, the movable sleeve 4 will reset under the elastic force of the spring 7.

[0034] Through holes 8 are formed at both ends of the movable sleeve 4 , and teeth 9 pass through the through holes 8 .

[0035] The setting of the through hole 8 allows the teeth 9 to move inside the through hole 8 when the rotating rod 6 rotates. In this solution, the rotation angle of the rotating rod 6 is limited, and it can only rotate in the direction close to the handle 5. When the spring 7 applies a thrust to the rotating rod 6 in the direction of the clamping arm 2, since the rotating rod 6 cannot rotate in the direction close to the clamping arm 2, the teeth 9 will not disengage from the tooth groove 3 and the movable sleeve 4 cannot move.

[0036] A torsion spring 10 is installed at the position where the rotating rod 6 is rotatably connected to the movable sleeve 4.

[0037] The torsion spring 10 is arranged so that after the user releases the rotating rod 6, the rotating rod 6 will be reset under the elastic force of the torsion spring 10. Therefore, when the user moves the handle 5 to any position, he only needs to slightly loosen the rotating rod 6 to reset it, so that the teeth 9 can be engaged with the tooth groove 3 at the current position, thereby fixing the movable sleeve 4 at the current position.

[0038] Working principle:

[0039] When in use, the user presses the palm against the handle 5, and then rotates the rotating rod 6 towards the handle 5 with the index finger and middle finger respectively, so that the rotating rod 6 drives the tooth 9 to rotate in the through hole 8, and squeezes the torsion spring 10, thereby making the tooth 9 disengage from the tooth groove 3. When the tooth 9 disengages from the tooth groove 3, the user can directly pull the movable sleeve 4 to slide at the outer end of the handle 1. When the movable sleeve 4 moves towards the clamping arm 2, it will squeeze a pair of clamping arms 2, causing the pair of clamping arms 2 to close. When the movable sleeve 4 moves away from the clamping arm 2, the pair of clamping arms 2 will reset under the elastic action. Thus, by sliding the movable sleeve 4, the clamping force of the pair of clamping arms 2 can be adjusted. When the user pulls the movable sleeve 4 towards the handle 5, the movable sleeve 4 will squeeze the spring 7. When the user appropriately reduces the pulling force on the rotating rod 6, the movable sleeve 4 will reset under the elastic force of the spring 7, and at the same time, the rotating rod 6 will reset under the elastic force of the torsion spring 10. When the user completely releases the rotating rod 6, the tooth 9 will be engaged with the tooth groove 3 at the current position, thereby fixing the movable sleeve 4 at the current position.

[0040] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improved concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
