Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a hemostatic device for surgery. Background Technology

[0002] In vascular surgery, after fully exposing the blood vessels, temporary occlusion is necessary to control bleeding, maintain a clear surgical field, reduce surgical time, decrease postoperative complications, improve surgical precision, reduce the risk of cardiovascular events, and protect distal tissues.

[0003] In vascular surgery, vascular occlusion often needs to be performed quickly and easily, while also being able to effectively control and rapidly release the occlusion. The hemostatic device must meet requirements such as preventing iatrogenic trauma to the blood vessel.

[0004] Currently, the primary hemostatic device used in clinical surgery is the vascular clamp, which achieves vascular occlusion by clamping the vessel with a metal clamp. While using the clamp, vascular slings are also needed at the proximal and distal ends of the vessel to effectively control it. Commonly used vascular clamps are relatively large (arms longer than 10cm) and are of a mechanical metal structure, making it impossible to freely change shape according to the surgical area and the vessel's course. Furthermore, after occluding the vessel, the clamp remains within the surgical area, often affecting further surgical procedures and interfering with delicate vascular surgeries, especially in confined spaces (such as small incisions). Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a hemostatic device for surgery, which solves the problem that the metal vascular clamps in the prior art cannot be bent, thus obstructing the surgical field of vision and affecting the surgical operation.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a hemostatic device for surgery, including a tourniquet and a binding structure. The tourniquet can be connected to the binding structure. The tourniquet can be infinitely adjusted and tightened to bind blood vessels. The binding structure is used to lock the tourniquet.

[0008] The binding structure includes a first connecting seat and a cable tie, the cable tie being able to pass through the first connecting seat and wrap around the tourniquet;

[0009] The first connecting seat includes a first seat body, a cable tie groove, and a locking tooth. The cable tie groove is disposed on the first seat body, and the locking tooth is disposed on the cable tie groove. The cable tie can pass through the cable tie groove and form a cable tie sleeve with the first seat body. The cable tie sleeve is used to lock the tourniquet.

[0010] The cable tie includes a cable body and connecting grooves. The connecting end of the cable body is connected to the first base, and the other end of the cable body is a free end. Multiple connecting grooves are provided and arranged on the cable body along the length direction of the cable body. The locking teeth can connect with the connecting grooves and prevent the cable body from moving in the direction of the tourniquet, and prevent the inner diameter of the cable tie sleeve from increasing.

[0011] Alternatively, the binding structure includes a second connecting seat, a first connecting strip, and a second connecting strip. The first connecting strip and the second connecting strip are respectively disposed at both ends of the second connecting seat. One end face of the first connecting strip and the second connecting seat forms a first clamp, and the other end face of the second connecting strip and the second connecting seat forms a second clamp. The first clamp and the second clamp are respectively used to connect to both ends of the tourniquet, thereby locking the tourniquet.

[0012] Furthermore, the second connecting seat includes a second seat body; the first connecting strip includes a retaining strip, one end of which is connected to the second seat body, and the other end of which is a free end.

[0013] Furthermore, the clamping strip is a C-shaped connecting strip, and the distance between the inner wall of the clamping strip and the second connecting seat and the second seat body is smaller than the outer diameter of the tourniquet, so that the first clamp can clamp the tourniquet.

[0014] Furthermore, the second connecting seat also includes a seat protrusion, which is disposed on the end face of the second seat body opposite to the first connecting bar and the second connecting bar.

[0015] Furthermore, the first connecting strip also includes a toothed strip, which is disposed on the clamping strip; both the seat tooth and the toothed strip can connect with the outer wall of the tourniquet, increasing the contact area between the first clamp and the tourniquet.

[0016] Furthermore, the second connecting seat also includes a connecting groove, which is disposed on the outer wall of the second seat body.

[0017] Furthermore, the first connecting strip also includes a strip protrusion, which is disposed on the free end of the locking strip; when the locking strip is pressed toward the second seat, the strip protrusion can connect with the connecting strip groove, the distance between the locking strip and the second seat becomes smaller, and the first clamp further tightens the tourniquet.

[0018] Furthermore, the first connecting strip and the second connecting strip have the same structure, and the first clamp and the second clamp have the same structure.

[0019] Furthermore, the tourniquet is a soft tourniquet.

[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0021] (1) The tourniquet of the hemostatic device of this utility model can be infinitely adjusted and tightened to the blood vessel. Pulling the free end of the tourniquet body tightens the tourniquet sleeve. The tourniquet body is connected to the tourniquet and the tourniquet is locked. The locking teeth are connected to the connecting groove, which can prevent the inner diameter of the tourniquet sleeve from increasing, thereby preventing the inner diameter of the blocking loop from changing and maintaining the blockage of the blood vessel.

[0022] (2) The tourniquet of the hemostatic device of this utility model is a soft tourniquet; during the operation, the tourniquet can be bent. According to the needs of the operation, the medical staff can bend the tourniquet in any direction. The tourniquet will not cover the operation area and will not affect the operation; the tourniquet is an elastic tourniquet that can be stretched and rebounded in the length direction and can tighten blood vessels.

[0023] (3) The present invention has multiple locking holes, which are continuously arranged along the length of the tourniquet. Different locking holes can be connected to locking posts to form blocking loops with different inner diameters, so that the hemostasis device of this embodiment can be applied to blood vessels of different thicknesses.

[0024] (4) In this utility model, the first connecting strip and the second connecting seat of the hemostatic device form a first clamp at one end, and the second connecting strip and the second connecting seat form a second clamp at the other end. The first clamp and the second clamp are respectively connected to the two ends of the tourniquet, thereby locking the tourniquet, preventing the inner diameter of the tourniquet sleeve from increasing, and maintaining the blockage of the blood vessel. Medical staff only need to pinch the second connecting seat with one hand and pull the tourniquet with the other hand to block the blood vessel. The operation is simple and shortens the operation time.

Detailed Implementation

[0033] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.

[0034] Example 1:

[0035] A specific embodiment of this utility model is as follows: Figure 1 As shown, a hemostatic device for surgery (hereinafter referred to as the hemostatic device) includes a tourniquet 1 and a binding structure, wherein the tourniquet 1 can be connected to the binding structure. The tourniquet 1 is used to wrap around the patient's blood vessels, and the binding structure is used to tighten the tourniquet 1, thereby blocking the blood flow in the blood vessels.

[0036] Preferably, tourniquet 1 is a soft tourniquet. During surgery, tourniquet 1 can be bent, and medical staff can bend tourniquet 1 in any direction as needed. Tourniquet 1 will not obstruct the operating area and will not affect the surgical procedure.

[0037] Preferred, such as Figure 1 As shown, the binding structure of this embodiment includes a snap-fit ​​unit 2 and a snap-fit ​​hole 3. Both the snap-fit ​​unit 2 and the snap-fit ​​hole 3 are disposed on the tourniquet 1. The snap-fit ​​unit 2 can be inserted into the snap-fit ​​hole 3 to block the blood vessel.

[0038] Preferably, tourniquet 1 is an elastic tourniquet that can stretch and rebound in the length direction, thereby tightening the blood vessel.

[0039] Preferably, the locking unit 2 includes a locking post 21 and a blocking block 22. The locking post 21 is disposed at the end of the tourniquet 1, and the blocking block 22 is disposed at the end of the locking post 21. When the tourniquet 1 is bent, the locking post 21 can be inserted into the locking hole 3, thereby forming an elastic blocking loop at one end of the tourniquet 1. The blocking loop is used to encircle and block the blood vessel. The outer diameter of the blocking block 22 is larger than the inner diameter of the locking hole 3, and it can prevent the locking post 21 from disengaging from the locking hole 3.

[0040] Preferably, multiple locking holes 3 are provided and are continuously arranged along the length of the tourniquet 1. Different locking holes 3 can be connected to the locking post 21 to form blocking loops with different inner diameters, thereby enabling the hemostasis device of this embodiment to be applicable to blood vessels of different diameters.

[0041] Compared to existing technologies, the tourniquet 1 of the hemostasis device in this embodiment is a soft tourniquet. During surgery, the tourniquet 1 can be bent, and medical staff can bend the tourniquet 1 in any direction as needed. The tourniquet 1 will not obstruct the operating area and will not affect the surgical procedure. The tourniquet 1 is an elastic tourniquet, which can be stretched and rebounded in the length direction, and can tighten the blood vessel. Multiple locking holes 3 are provided and are continuously arranged along the length direction of the tourniquet 1. Different locking holes 3 can be connected to the locking post 21 to form blocking loops with different inner diameters, so that the hemostasis device of this embodiment can be applied to blood vessels of different thicknesses.

[0042] Example 2:

[0043] In Example 1, the distance of the locking hole 3 is fixed, and the inner diameter of the blocking loop cannot be adjusted steplessly. Therefore, as... Figure 2 As shown, based on Embodiment 1, Embodiment 2 improves the binding structure of Embodiment 1 by removing the snap-fit ​​unit 2 and the snap-fit ​​hole 3, and adding a first connecting seat 4 and a cable tie 5. The connecting end of the cable tie 5 is connected to the first connecting seat 4, and the other end of the cable tie 5 is a free end that can pass through the first connecting seat 4 and wrap around the tourniquet 1. The tourniquet 1 can be infinitely adjusted and tightened to bind the blood vessel. The binding structure of this embodiment is used to lock the tourniquet 1, prevent the inner diameter of the occlusion loop from changing, and maintain the occlusion of the blood vessel.

[0044] Preferred, such as Figure 3 As shown, the first connecting seat 4 includes a first seat body 41, a cable tie groove, and a locking tooth 42. The cable tie groove is disposed on the first seat body 41, and the locking tooth 42 is disposed on the cable tie groove. The cable tie 5 can pass through the cable tie groove and form a cable tie sleeve with the first seat body 41. The cable tie sleeve is used to lock the tourniquet 1. The locking tooth 42 is used to connect with the cable tie 5 to prevent the inner diameter of the cable tie sleeve from increasing.

[0045] Preferably, the cable tie 5 includes a tie body 51 and connecting grooves 52. The connecting end of the tie body 51 is connected to the first connecting seat 4, and the other end of the tie body 51 is a free end. Multiple connecting grooves 52 are provided and arranged on the tie body 51 along its length. The locking teeth 42 can connect with the connecting grooves 52 and prevent the tie body 51 from moving towards the tourniquet 1, thus preventing the inner diameter of the cable tie sleeve from increasing.

[0046] Medical staff pass the free end of the band body 51 through the band groove, forming a band sleeve with the first seat 41. They then pass both ends of the tourniquet 1 wrapped around the blood vessel through the band sleeve and pull the tourniquet 1 away from the blood vessel, thus blocking the blood vessel. Pulling the free end of the band body 51 tightens the band sleeve, connecting the band body 51 with the tourniquet 1 and locking the tourniquet 1. The locking teeth 42 connect with the connecting groove 52 to prevent the inner diameter of the band sleeve from increasing, thereby preventing changes in the inner diameter of the blocking loop and maintaining the blockage of the blood vessel.

[0047] Compared to Embodiment 1, the tourniquet 1 of the hemostatic device in this embodiment can be infinitely adjusted and tightened to the blood vessel. Pulling the free end of the tourniquet body 51 tightens the tourniquet sleeve. The tourniquet body 51 is connected to the tourniquet 1 and the tourniquet 1 is locked. The locking teeth 42 are connected to the connecting groove 52, which can prevent the inner diameter of the tourniquet sleeve from increasing, thereby preventing the inner diameter of the blocking loop from changing and maintaining the blockage of the blood vessel.

[0048] Example 3:

[0049] When using the hemostatic device of Embodiment 2 to occlude a blood vessel, one medical worker needs to pull the tourniquet 1 with one hand, while another medical worker needs to pinch the first connecting seat 4 with one hand and pull the cable tie 5 with the other hand to occlude the blood vessel. Therefore, as... Figure 4 As shown, Embodiment 3 improves upon the binding structure of Embodiment 2 by removing the first connecting seat 4 and the cable tie 5, and adding a second connecting seat 6, a first connecting strip 7, and a second connecting strip 8. The first connecting strip 7 and the second connecting strip 8 are respectively positioned at both ends of the second connecting seat 6. One end face of the first connecting strip 7 and the second connecting seat 6 forms a first clamp, and the other end face of the second connecting strip 8 and the second connecting seat 6 forms a second clamp. The first clamp and the second clamp are used to connect to both ends of the tourniquet 1, thereby locking the tourniquet 1, preventing the inner diameter of the cable tie from increasing, and maintaining the occlusion of the blood vessel. Medical personnel only need to pinch the second connecting seat 6 with one hand and pull the tourniquet 1 with the other hand to perform the occlusion operation. The structures of the first connecting strip 7 and the second connecting strip 8 are identical, as are the structures of the first clamp and the second clamp.

[0050] Preferred, such as Figure 5As shown, the second connecting seat 6 includes a second seat body 61. The first connecting strip 7 includes a retaining strip 71, which is a C-shaped connecting strip. One end of the retaining strip 71 is connected to the second seat body 61, and the other end of the retaining strip 71 is a free end. The distance between the inner wall of the retaining strip 71 and the second seat body 61 is less than the outer diameter of the tourniquet 1, and the first clamp can clamp the tourniquet 1.

[0051] Preferably, to enhance the anti-slip performance of the binding structure in this embodiment, the second connecting seat 6 further includes a seat tooth 62, which is disposed on the end face of the second seat body 61 opposite to the first connecting strip 7 and the second connecting strip 8. The first connecting strip 7 also includes a strip tooth 72, which is disposed on the retaining strip 71. Both the seat tooth 62 and the strip tooth 72 can connect with the outer wall of the tourniquet 1, increasing the contact area between the first clamp and the tourniquet 1 and enhancing the anti-slip performance of the binding structure in this embodiment.

[0052] Preferably, to further tighten the tourniquet 1, the second connecting seat 6 also includes a connecting groove 63, which is disposed on the outer wall of the second seat body 61. The first connecting strip 7 also includes a protrusion 73, which is disposed on the free end of the retaining strip 71. When the retaining strip 71 is pressed towards the second seat body 61, the protrusion 73 can connect with the connecting groove 63, the distance between the retaining strip 71 and the second seat body 61 decreases, and the first clamp further tightens the tourniquet 1.

[0053] Compared to Embodiment 2, in this embodiment, one end face of the first connecting strip 7 and the second connecting seat 6 of the hemostatic device constitutes a first clamp, and the other end face of the second connecting strip 8 and the second connecting seat 6 constitutes a second clamp. The first clamp and the second clamp are respectively connected to both ends of the tourniquet 1, thereby locking the tourniquet 1, preventing the inner diameter of the tourniquet sleeve from increasing, and maintaining the occlusion of the blood vessel. Medical personnel only need to pinch the second connecting seat 6 with one hand and pull the tourniquet 1 with the other hand to perform the occlusion operation, which is simple and shortens the operation time.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
