Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a continuous hair hemostatic clip device, which comprises an outer tube 1, a connecting tube 2 sleeved in the outer tube 1, and a fixing rod 3 sleeved in the connecting tube 2, and further comprises a plurality of hemostatic clips 4 accommodated in the outer tube 1.

As shown in fig. 1, 6 and 7, the outer tube 1 is a spring tube, the connecting tube 2 is a flat spring tube or a plastic tube with better toughness, and the connecting tube 2 is slidably connected with the outer tube 1. The fixing rod 3 is a nickel titanium polished rod or a stainless steel polished rod, the fixing rod 3 is in sliding connection with the connecting pipe 2, the hemostatic clips 4 are sequentially meshed and sleeved on the fixing rod 3, and one hemostatic clip 4 at the rearmost end of the hemostatic clips 4 is clamped with the connecting pipe 2. In this embodiment, three hemostatic clips 4 are sleeved on the fixing rod 3 in sequence, and it can be understood that in other embodiments, the number of hemostatic clips 4 sleeved on the fixing rod 3 may be two, four or more.

As shown in fig. 2 to 5, the hemostatic clip 4 is integrally formed by an elastic material, the hemostatic clip 4 is approximately V-shaped, the hemostatic clip 4 includes a connecting portion 41 and two clamping pieces 42, the two clamping pieces 42 are connected by the connecting portion 41, the connecting portion 41 is curved, two engaging pieces 43 are provided on one side of the connecting portion 41 away from the clamping pieces 42, and the engaging pieces 43 are in a convex structure. The front end of the clip 42 is bent inward, the front end of the clip 42 is provided with a clip edge 421, and the clip edge 421 is provided with a bite 422. The clamping edges 421 are also provided with clamping teeth 423, and the clamping teeth 423 on the two clamping edges 421 are meshed. The engagement openings 422 on the two clamping edges 421 of the hemostatic clip 4 are capable of engaging the two engagement members 43.

As shown in fig. 2 to 5, two clamping pieces 42 of the same hemostatic clamp 4 are respectively provided with an elastic arm 44 and a slotted hole 45, one end of the elastic arm 44 is fixedly connected with the clamping pieces, and the elastic arm 44 can deform. The elastic arm 44 is provided with a clamping hole 46 at one side far away from the clamping piece 42, a slot 47 is arranged at the slot 45, and the clamping hole 46 and the slot 47 can be clamped with each other in the clamping hole 46.

Specifically, as shown in fig. 6, the end of the connecting tube 2 is provided with a clamping groove 21, and two engaging members 43 of one hemostatic clip 4 at the rearmost end of the plurality of hemostatic clips 4 are engaged with the clamping groove 21.

As shown in fig. 7, when a plurality of hemostatic clips 4 are connected, the engagement opening 422 of the subsequent hemostatic clip 4 engages the two engagement members 43 of the previous hemostatic clip 4, thereby achieving connection between hemostatic clips 4. Two engaging members 43 on the rearmost one of the plurality of hemostatic clips 4 are engaged with the engaging grooves 21 on the connecting tube 2, thereby connecting the hemostatic clip 4 with the connecting tube 2.

The use process of the continuous hair hemostatic clamp device is as follows: as shown in fig. 1, 8 to 11, the hemostatic clip device of the present utility model is first extended into a human body near a mucosal tissue or a blood vessel to be hemostatic, the connecting tube 2 is driven to move forward by an external force, the connecting tube 2 sequentially pushes the plurality of hemostatic clips 4 to move forward, and when the elastic arm 44 in the first hemostatic clip 4 at the forefront is separated from the fixing rod 3, the elastic arm 44 is completely sprung under no force. Then the connecting pipe 2 continues to push the hemostatic clamp 4 to move forwards, the clamping piece 42 of the hemostatic clamp 4 gradually breaks away from the limit of the outer pipe 1, and the hemostatic clamp 4 is fully unfolded under the action of self elastic force due to the fact that the hemostatic clamp 4 is integrally formed by elastic materials.

After the hemostatic clamp 4 clamps the tissue wound or the blood vessel, the connecting pipe 2 is driven to move backwards by external force, so that the connecting pipe 2 drives the hemostatic clamp 4 to move backwards, the clamping piece 42 of the hemostatic clamp 4 is gradually tightened until the hemostatic clamp 4 is closed under the action of the outer pipe 1, and the elastic arm 44 is retracted into the slotted hole 45. The connecting pipe 2 continues to move backwards until the elastic arm 44 is abutted against the fixing rod 3, the elastic arm 44 rotates by a certain angle under the action of the force exerted by the fixing rod 3, the clamping hole 46 on the elastic arm 44 is propped against the groove buckle 47 of the groove hole 45 to be clamped together, and at the moment, the hemostatic clip 4 is locked and cannot be opened. Finally, the connecting pipe 2 is pushed to move forwards, and as the two clamping pieces 42 of the second hemostatic clamp 4 at the forefront are gradually opened, the clamping openings 422 on the clamping edges 421 of the hemostatic clamp 4 are not clamped with the clamping pieces 43 of the first hemostatic clamp 4 at the forefront, so that the first hemostatic clamp 4 is released, and the operation is simple. When the continuous hemostatic clip 4 is needed to perform hemostatic operation, the operation is repeated, and the use is very convenient.
