Description

Technical Field

[0001] The utility model relates to the field of vascular clamps, in particular to a simple forceps-type vascular clamp. Background Art

[0002] Vascular clamps, also known as hemostatic forceps, are an important instrument commonly used in surgical operations.

[0003] Traditional vascular clamps generally have a locking structure, such as the existing patent document "CN211460365U A General Surgery Illuminated Hemostatic Forceps", which provides a limit strip on the second clamp rod, and the limit strip is engraved with lines that allow the left and right second clamp rods to clamp each other. After the hemostatic forceps are closed to stop bleeding, the lines between the limit strips clamp each other to provide a limit lock; although the above-mentioned existing technology can provide locking after the hemostatic forceps are clamped, during the opening process of the hemostatic forceps, due to the mutually clamping locking design, the two clamp rods of the hemostatic forceps need to be pried apart with both hands using a large force, thereby causing a technical problem of inconvenience in opening the hemostatic forceps. For junior doctors who are not proficient in left and right hand operation, sometimes they cannot easily open the closed vascular clamp and need to change hands to operate, which in turn has a certain impact on the surgeon and wastes time.

[0040] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0041] like Figure 1-3 As shown, a simple forceps-type vascular forceps includes a first forceps rod 1 and a second forceps rod 2; also includes: a spring piece 4, which is installed between the first forceps rod 1 and the second forceps rod 2; a locking mechanism, which includes a locking block 6 installed on the first forceps rod 1 and a lock body 8 installed on the second forceps rod 2; after the locking block 6 is inserted into the lock body 8, the lock body 8 provides locking for the locking block 6; a press-unlocking part 7, which can release the lock of the locking block 6, and the press-unlocking part 7 is installed on the second forceps rod 2; an elbow 3, the number of the elbows 3 is two, and the two elbows 3 are respectively arranged at the bottom end of the first forceps rod 1 and the bottom end of the second forceps rod 2.

[0042] like Figure 1 As shown, as a specific technical solution, the side walls of the first clamp rod 1 and the side walls of the second clamp rod 2 are both provided with a plurality of evenly distributed anti-slip protrusions.

[0043] When holding it, the anti-slip protrusions come into contact with the hand to prevent slipping.

[0044] like Figure 1 As shown, as a specific technical solution, the spring piece 4 is U-shaped, and both ends of the spring piece 4 are fixedly connected to the first clamp rod 1 and the second clamp rod 2 respectively.

[0045] After the entire vascular clamp is closed, the spring piece 4 is compressed; when opening, the first clamp rod 1 and the second clamp rod 2 are moved away from each other by the compression force, so as to realize automatic opening.

[0046] like Figure 2-3As shown in the figure, as a specific technical solution, the lock body 8 includes a guide housing 801, a slider 803, a seat 805, and a spring piece 806. The guide housing 801 is fixedly mounted on the second clamp rod 2, and the slider 803 is slidably mounted in the guide housing 801. A third spring 802 is provided in the guide housing 801, one end of the third spring 802 is fixedly connected to the wall of the guide housing 801, and the other end of the third spring 802 is fixedly connected to the slider 803. The seat 805 is fixedly connected to the slider 803 facing the lock block 6, and a spring piece 806 is fixedly connected to both sides of the seat 805. A retaining ring 804 is fixedly installed in the guide housing 801, and the outer annular surface of the retaining ring 804 is fixedly connected to the inner wall of the guide housing 801.

The ends of the third spring 802 are respectively fixed to the wall of the positioning hole 8031 and the end face of the post 808. A slot 8011 is formed on the inner sidewall of the guide housing 801 to accommodate the post 808.

[0047] During the process of clamping the blood vessel, the first clamp rod 1 and the second clamp rod 2 move closer to each other, and the locking block 6 moves closer to the locking body 8. Figure 2 As shown, the lock block 6 is in a state where it is not inserted into the lock body 8; while the lock block 6 is inserted into the lock body 8, the lock block 6 pushes the seat body 805, causing the seat body 805 and the slider 803 to move into the guide shell 801, compressing the third spring 802 until the slider 803 contacts the retaining ring 804. During the above process, the spring piece 806 on the seat body 805 also moves into the guide shell 801 together, and the spring piece 806 is squeezed by the inner cavity of the guide shell 801. The protrusion at the end of the spring piece 806 wraps the head of the lock block 6, as shown in FIG. Figure 3 As shown, the insertion of the locking block 6 is completed and locking is achieved. At the same time, the column 808 is aligned with the slot 8011, wherein the fourth spring 807 in the positioning hole 8031 is in a compressed state. Through the elastic force of the fourth spring 807, the column 808 is inserted into the slot 8011 to achieve the positioning of the slider 803, thereby maintaining the locked state.

[0048] Through the above-mentioned design of the locking block 6 and the locking body 8, automatic locking in the clamped state is achieved after the vascular clamp is clamped.

[0049] like Figure 2-3As shown in the figure, as a specific technical solution, the press-unlocking portion 7 includes a pressing block 701, a movable rod 702, a first spring 703, a second spring 704 and a push block 705. A guide hole 201 and a concave hole 202 are opened on the side wall of the second clamp rod 2. The guide hole 201 extends into the guide shell 801, and the guide hole 201 is connected to the slot 8011. The movable rod 702 is connected to the guide hole 201, and the movable rod 702 passes through the concave hole 202. One end of the movable rod 702 is fixed A pressing block 701 is connected, and the pressing block 701 is elastically connected to the second clamp rod 2 via a first spring 703 provided in the recessed hole 202. The movable rod 702 extends into the slot 8011, and the push block 705 is slidably installed in the slot 8011, and the movable rod 702 contacts the push block 705. A second spring 704 is provided in the slot 8011, one end of the second spring 704 is fixedly connected to the push block 705, and the other end of the second spring 704 is fixedly connected to the wall of the slot 8011. A first inclined surface is provided on the side of the end of the movable rod 702 away from the pressing block 701, and a second inclined surface is provided on one side of the push block 705, and the first inclined surface and the second inclined surface are in contact with each other. The aperture of the recessed hole 202 is smaller than the diameter of the pressing block 701, and there is a distance between the pressing block 701 and the side wall of the second clamp rod 2.

[0050] When the clamp is opened, the pressing block 701 is pressed until the pressing block 701 fits into the surface of the second embedded rod. During the above process, the pressing block 701 compresses the first spring 703, and the movable rod 702 moves with the pressing block 701 and is guided by the guide hole 201, so that the movable rod 702 moves into the slot 8011. The first inclined surface of the movable rod 702 squeezes the second inclined surface of the pushing block 705, so that the pushing block 705 moves along the slot 8011, and the pushing block 705 pushes the plug 808 out of the slot 8011, while compressing the fourth spring 807 and stretching the second spring 704. After the pushing block 705 is pushed out, the slider 803 loses its position, and the elastic force of the third spring 802 pushes the slider 803 to reset, and the structure of the lock body 8 is restored to the state as shown. Figure 2 In the state shown, the locking of the locking block 6 is canceled. After unlocking, the elastic force of the spring piece 4 separates and opens the first pliers rod 1 and the second pliers rod 2.

[0051] In the above description, to open the vascular clamp, one only needs to press the pressing block 701 , which makes the opening operation simple and can be performed with one hand.
