Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a vascular occlusion device. Background Art

[0002] In vascular surgery, after fully exposing the blood vessel, temporary occlusion is required, which can achieve the purposes of controlling bleeding, maintaining a clear surgical field, reducing the operation time, reducing postoperative complications, improving the surgical precision, reducing the risk of cardiovascular events, protecting distal tissues, etc.

[0003] In vascular surgery, vascular occlusion often needs to be implemented quickly and conveniently, and at the same time, it can effectively control and quickly release the occlusion. The occlusion device is required to cause no iatrogenic trauma to the blood vessel.

[0004] Currently, the vascular occlusion devices used clinically are mainly vascular occlusion forceps, which achieve the purpose of vascular occlusion by the way of metal clamping. When applying the occlusion forceps, vascular slings are also required to cooperate at the distal and proximal ends of the blood vessel to effectively control the blood vessel. The commonly used vascular occlusion forceps are relatively large in size (the length of the forceps arm is more than 10 cm), and are of a metal mechanical structure, and cannot freely change the shape according to the surgical area and the blood vessel course. At the same time, after using the occlusion forceps to occlude the blood vessel, the occlusion forceps are located in the surgical area, which often affects further surgical operations and brings certain interference to delicate vascular surgeries, especially when performing surgeries in a narrow space (such as within a small incision). Summary of the Invention

[0005] In view of the above deficiencies of the prior art, the present invention provides a vascular occlusion device, which is used to solve the problem that the metal vascular occlusion forceps in the prior art cannot be bent, block the surgical field of view, and affect surgical operations.

[0006] To achieve the above invention purpose, the technical solution adopted by the present invention is as follows:

[0007] The present invention provides a vascular occlusion device, which includes an occlusion band and a locking mechanism. The occlusion band can be connected to the locking mechanism. The occlusion band is used to wind around the blood vessel of a patient, and the locking mechanism is used to tighten the occlusion band so that the occlusion band occludes the blood flow in the blood vessel.

[0008] Further, the occlusion band is a soft occlusion band.

[0009] Further, the occlusion band is an elastic occlusion band, which can be stretched and rebounded in the length direction, and thus can tighten the blood vessel.

[0010] Further, the locking mechanism includes a clamping unit and a clamping hole. Both the clamping unit and the clamping hole are arranged on the occlusion band, and the clamping unit can be inserted into the clamping hole to occlude the blood vessel.

[0011] Further, the clamping unit includes a clamping post disposed at an end of the blocking band. When the blocking band is bent, the clamping post can be inserted into the card hole, so that one end of the blocking band forms an elastic blocking loop for sleeving a blood vessel and blocking the blood vessel.

[0012] Further, the clamping unit further includes a blocking block disposed at an end of the clamping post; an outer diameter of the blocking block is greater than an inner diameter of the card hole, and the blocking block can prevent the clamping post from disengaging from the card hole.

[0013] Further, a plurality of the card holes are provided and are continuously arranged along a length direction of the blocking band; different ones of the card holes can be connected to the clamping post, thereby forming the blocking loops with different inner diameters.

[0014] Further, the locking mechanism includes a second locking block and a first clamping plate. The first clamping plate is disposed on the second locking block, and one end face of the first clamping plate and the second locking block forms a first clamping hoop.

[0015] Further, the locking mechanism further includes a second clamping plate, and the second clamping plate and the other end face of the second locking block form a second clamping hoop.

[0016] Further, the second locking block includes a second block body; the first clamping plate includes a plate body. One end of the plate body is connected to the second block body, and the other end of the plate body is a free end. The first clamping hoop can clamp the blocking band.

[0017] Compared with the prior art, the present invention can at least achieve one of the following beneficial effects:

[0018] (1) The blocking band of the blocking device of the present invention is a soft blocking band; during the operation, the blocking band can be bent. According to the operation needs, medical staff can bend the blocking band in any direction. The blocking band will not block the operation area and will not affect the operation; the blocking band is an elastic blocking band that can be stretched and rebounded in the length direction and can tighten the blood vessel.

[0019] (2) A plurality of the card holes are provided in the present invention and are continuously arranged along the length direction of the blocking band. Different card holes can be connected to the clamping post, thereby forming the blocking loops with different inner diameters, so that the blocking device of the present embodiment can be applicable to blood vessels of different thicknesses.

[0020] (3) The blocking band of the blocking device of the present invention can be adjusted steplessly and tighten the blood vessel. By pulling the free end of the belt body, the locking belt sleeve is tightened. The belt body is connected to the blocking band and locks the blocking band. The convex projection is connected to the card slot, which can prevent the inner diameter of the locking belt sleeve from becoming larger, thereby preventing the inner diameter of the blocking loop from changing and maintaining the blocking of the blood vessel.

[0021] (4) One end face of the first clamping plate and the second locking block of the blocking device of the present invention forms a first clamp, and the other end face of the second clamping plate and the second locking block forms a second clamp. The first clamp and the second clamp are respectively connected to both ends of the blocking belt, thereby locking the blocking belt, preventing the inner diameter of the locking belt sleeve from becoming larger, and maintaining the blockage of the blood vessel; medical staff only need to pinch the second locking block with one hand and pull the blocking belt with the other hand to block the blood vessel. The operation is simple and the operation time is shortened.

[0022] (5) The transmission unit of the present invention can drive the runner and drive the blocking belt to move in the first clamp, thereby changing the inner diameter of the locking belt sleeve and tightening or relaxing the blood vessel of the patient; when blocking the blood vessel, medical staff can perform the blocking operation outside the patient's body without touching the patient's blood vessel, reducing the risk of damaging the blood vessel.

[0023] In the present invention, the above technical solutions can be combined with each other to achieve more preferred combination solutions.

[0048] Embodiment 3:

[0049] When using the blocking device of Embodiment 2 to block the blood vessel, one medical staff needs to pull the blocking belt 1 with one hand, and another medical staff needs to pinch the first locking block 4 with one hand and pull the locking belt 5 with the other hand to block the blood vessel. Therefore, as Figure 4 shown, Embodiment 3 improves the locking mechanism of Embodiment 2. The first locking block 4 and the locking belt 5 are removed, and a second locking block 6, a first clamping plate 7 and a second clamping plate 8 are added. The first clamping plate 7 and the second clamping plate 8 are respectively arranged at both ends of the second locking block 6.

[0054] Embodiment 4:

[0055] When the blocking devices in Embodiments 1-3 block blood vessels, the hands of medical staff need to come into contact with the blood vessels of patients, which poses a risk of accidental contact and damage to the blood vessels. Therefore, as Figure 6As shown, on the basis of Embodiment 3, Embodiment 4 adds a transmission unit 9 and improves the second locking block 6 of Embodiment 3. The anti-slip teeth 62 provided on the end face opposite to the first clamping plate 7 are removed, and a runner 64 is added. The transmission unit 9 can drive the runner 64 and also prevent the runner 64 from rotating. The rolling surface of the runner 64 can be connected to the outer wall of the blocking belt 1. The runner 64 can rotate and drive the blocking belt 1 to move within the first clamp, thereby changing the inner diameter of the locking belt sleeve and tightening or loosening the patient's blood vessel. When blocking the blood vessel, medical staff can perform the blocking operation outside the patient's body without contacting the patient's blood vessel, reducing the risk of damaging the blood vessel.

[0056] Preferably, the runner 64 is arranged on the second block body 61. The second block body 61 includes a runner groove, and the runner 64 is rotatably connected to the runner groove.

[0057] Preferably, the runner 64 is a gear, and the teeth of the runner 64 increase the friction force with the outer wall of the blocking belt 1 to prevent the blocking belt 1 from slipping with the runner 64.

[0059] Preferably, the transmission unit 9 includes a housing 91, a driving gear 92 and a driving rack 93. The driving gear 92 is rotatably connected to the housing 91, and the driving rack 93 is arranged on the housing 91 and can slide on the housing 91. The housing 91 can be connected to the hook 65, and the hook 65 prevents the housing 91 from detaching from the second block body 61. The driving rack 93 can be engaged with the driving gear 92 and make the driving gear 92 rotate forward.

[0060] Preferably, in order to realize the quick connection between the transmission unit 9 and the runner 64, the second locking block 6 further includes a plug-in block 66, and the plug-in block 66 is connected to the end of the runner 64.

[0062] Preferably, in order to push the driving rack 93, the transmission unit 9 further includes an actuating assembly for pushing or pulling the driving rack 93. The actuating assembly can be connected to the housing 91 or detached from the housing 91. During the operation of blocking blood vessels, connecting the actuating assembly to the housing 91 enables pushing and pulling the driving rack 93 outside the patient's body to prevent damage to blood vessels; after blood vessel blocking, the actuating assembly can be detached from the housing 91 to avoid interfering with the operation.

[0063] Preferably, the actuating assembly includes a sheath 95 and a push rod 96. The sheath 95 can be connected to the housing 91, and the push rod 96 is arranged in the sheath 95.
