Technical Field

[0001] The utility model relates to the technical field of general surgical treatment, in particular to a hemostatic device for general surgical treatment. Background Art

[0002] Hemostatic devices for general surgery are medical devices used to control bleeding during surgery and surgical treatment. In surgery, controlling bleeding is very important because heavy bleeding may cause excessive blood loss in patients and even endanger their lives.

[0003] Hemostatic devices for general surgical treatment can reduce tissue damage during surgery, shorten recovery time, and improve the success rate of surgery. Therefore, it has been widely used in modern surgery and provides surgeons with more options and higher treatment effects.

[0004] At present, hemostatic devices used in general surgical treatment directly compress injured blood vessels and stop blood from flowing out by applying pressure, such as tourniquets or hemostatic forceps. However, most devices such as tourniquets use Velcro when connecting the ends. After being torn many times, they will become easy to fall off to a certain extent. Secondly, Velcro is also easy to absorb some garbage such as hair on it. In addition, after connecting the ends, the tightness of the tourniquet cannot be further adjusted. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a hemostatic device for general surgical treatment, which solves the problem mentioned in the above background technology that the connection between the connecting plates is unstable and the tightness of the tourniquet cannot be further adjusted after the connecting plates are connected together.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 2 The utility model provides a hemostatic device for general surgical treatment, comprising a tourniquet 1, which is made of soft material and can prevent blood from flowing out of injured blood vessels by applying pressure, thereby helping to stop bleeding. The left end of the tourniquet 1 is fixedly connected to a first connecting plate 2, and the right end of the tourniquet 1 is fixedly connected to a second connecting plate 3. The inner wall of the second connecting plate 3 is rotatably connected to a rotating shaft a14, and the bottom end of the rotating shaft a14 is fixedly connected to an elliptical block 4. The inner wall of the elliptical block 4 is clamped with the outer wall of the first connecting plate 2. The inner wall of the first connecting plate 2 is provided with a plurality of groups of elliptical grooves 5, and the outer wall of the elliptical block 4 is plugged with the inner wall of the elliptical groove 5. The elliptical groove 5 is aligned with the elliptical block 4 and buckled. When it passes through the elliptical block 4, the rotating elliptical block 4 drives the rotating shaft a14 to rotate, clamps the outer wall of the first connecting plate 2, and fixes the first connecting plate 2 to the outside of the second connecting plate 3. Both connecting plates are made of hard materials and are not easy to deform. The tightness of binding the bleeding site can be preliminarily adjusted through the plurality of groups of elliptical grooves 5.

[0023] See also Figure 1 and Figure 3The outer wall of the tourniquet 1 is slidably connected with a lightweight plastic plate 6, and a hemostatic pad 7 is fixedly connected to the bottom of the lightweight plastic plate 6. The hemostatic pad 7 is applied to the affected area to achieve a certain hemostatic effect, preventing the lightweight plastic plate 6 from directly contacting the affected area and causing the wound to worsen. The inner wall of the lightweight plastic plate 6 is rotatably connected with a rotating shaft b8, and an extrusion block 9 is fixedly connected to the outer wall of the rotating shaft b8. The outer wall of the extrusion block 9 contacts the inner wall of the tourniquet 1. One half of the extrusion block 9 is circular, and the other half is elliptical. When the rotating shaft b8 rotates, the extrusion block 9 is driven to rotate. The circular half ensures that no pressure is generated on the outer wall above the lightweight plastic plate 6 during rotation, while the elliptical half squeezes the tourniquet 1 to lift it up, so that more tourniquet 1 slides above the lightweight plastic plate 6, so that the hemostatic device is further tightened and can be further adjusted after being buckled. The inner wall of the rotating shaft b8 is elastically connected with the rotating shaft through a reset spring 10. The rotating assembly includes a knob 11, a rectangular protrusion structure is provided on the outer wall of the knob 11, which clamps the inner wall of the rotating shaft b8 to prevent it from falling off, one end of the return spring 10 is fixedly connected to the inner wall of the rotating shaft b8, and the other end of the return spring 10 is fixedly connected to the inner end of the knob 11. Pulling the knob 11 outward can stretch the return spring 10 and move it outward. At the same time, the elastic force generated by the deformation of the return spring 10 gives the knob 11 an inward pulling force to reset it. The inner wall of the knob 11 is fixedly connected to the limiting block 12, and the outer wall of the lightweight plastic plate 6 is provided with a plurality of groups of limiting grooves 13. The outer wall of the limiting block 12 is clamped with the inner wall of the limiting groove 13. The knob 11 can be pulled outward until the limiting block 12 and the limiting groove 13 are released, and then the knob 11 can be rotated to drive the extrusion block 9 to rotate, so as to further adjust the tightness of the tourniquet 1.

[0024] Working principle: apply the tourniquet 1 to the affected area and tighten it, align the elliptical groove 5 with the elliptical block 4 and buckle it in. After the elliptical block 4 passes through the elliptical groove 5, rotate the elliptical block 4 to clamp the first connecting plate 2 to fix the tourniquet 1 to the affected area. The locking structure is more stable than the general tearing structure. When the tourniquet 1 needs to be further adjusted in a more specific situation, pull the knob 11 outward until the limit block 12 and the limit groove 13 are disengaged, rotate the knob 11 to drive the extrusion block 9 to rotate, further squeeze the inner wall of the tourniquet 1 above the lightweight plastic plate 6 to further tighten the tourniquet 1, thereby achieving further tightening or loosening after the tourniquet 1 is fixed. After the adjustment is completed, release the knob 11, and the reset spring 10 pulls it back to its original position, driving the limit block 12 to re-enter the limit groove 13 to fix the position of the extrusion block 9.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
