Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a laparoscopic blood vessel repair device. Background Art

[0002] During thoracic surgery, free blood vessels are often involved, and the freeing process can easily lead to damage to the vessel walls, causing heavy bleeding and endangering the patient's life. To treat vascular injuries, needle and thread suturing is often required. Before suturing, a suction device is used to absorb the blood overflowing from the ruptured blood vessels to expose the field of view. However, the main operating port of current thoracoscopic surgery is often small, and it is impossible to insert multiple instruments at the same time to expose the field of view and adjust the angle, resulting in some angles that cannot be sutured. In addition, during the process of clearing the blood vessels, damage occurs on the back of the blood vessels, leaving almost no chance of suturing. This will lead to the failure of suture to stop bleeding, increase the chance of thoracotomy, and even death. Summary of the Invention

[0014] (3) Beneficial effects

[0015] The present invention provides a laparoscopic vascular lesion repair device.

The device is then adjusted to the appropriate position to aspirate bleeding. When no blood seeps out from the periphery of the device and all bleeding is aspirated by the device, it is determined that the device has completely covered the bleeding site. Liquid is then injected into the connecting tube via a syringe, and hydraulic pressure is applied to the rubber column in the branch tube, causing it to slide outward. During this sliding process, the rubber column abuts against the abutment portion of a titanium clip, causing the titanium clip to close the vascular lesion and achieve hemostasis. This method combines the device with the titanium clip, enabling the device to both aspirate bleeding and assist in locating the bleeding site while simultaneously clamping and stopping bleeding. This reduces the need for instruments to enter the patient's body, facilitates access to difficult angles or locations that are not directly exposed, improves surgical convenience, and reduces the learning curve for surgeons in learning hemostasis techniques.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] The present invention provides a laparoscopic vascular repair device, see Figure 1-Figure 5 The device comprises a vascular lesion repair device tube 100, one end of which is connected to a vacuum aspirator 400, and the other end of which is inserted into the patient's body for vacuum aspiration. The vacuum aspirator 400 is a device currently used in hospitals, and the end of the vascular lesion repair device tube 100, located near the vacuum aspirator 400, is configured to be connectable to the vacuum aspirator 400. The specific configuration is determined based on the model of the vacuum aspirator 400 and is not limited herein.

[0026] A titanium clip 200 is installed at the end of the vascular repair device 100, away from the vacuum aspirator 400. Part of the titanium clip 200 is located at the end of the vascular repair device 100. A drive assembly 300 is installed within the vascular repair device 100. The drive assembly 300 is connected to the titanium clip 200 and controls it to clamp the vascular lesion. With this arrangement, when performing thoracic surgery, if a blood vessel is damaged, the blood vessel damage repair device tube body 100 is inserted into the patient's body for negative pressure suction to suck out the bleeding and gradually find the bleeding point. When all the bleeding is sucked away from the blood vessel damage repair device tube body 100, it can be considered that the blood vessel damage repair device tube body 100 has covered all the bleeding points. The titanium clip 200 is controlled by the driving component 300 to clamp the bleeding point to achieve the purpose of hemostasis. This method combines the blood vessel damage repair device tube body 100 and the titanium clip 200, so that the structure can perform negative pressure suction on the bleeding and clamp to stop bleeding at the same time, reducing the number of instruments entering the patient's body, facilitating operations on positions with tricky angles or that cannot be directly exposed, and improving the convenience of the operation.

[0027] Among them, the titanium clamp 200 includes a first clamping part 210 and a second clamping part 220 in a V-shape. The first clamping part 210 and the second clamping part 220 are integrally formed at one end, and a clamping opening 230 for clamping the damaged blood vessel is formed at the other end. The first clamping part 210 and the second clamping part 220 are symmetrically arranged, and the clamping opening 230 is located on the side outside the blood vessel damage repairer tube body 100. The first clamping part 210 and the second clamping part 220 form an abutment part 240 on the side away from each other, and the driving component 300 controls the clamping opening 230 to perform a clamping action by abutting the abutment part 240.

[0028] An arc-shaped hole 110 is formed inside the vascular lesion repair device tube body 100 and at one end away from the negative pressure aspirator 400 . Two arc-shaped holes 110 are symmetrically formed on the tube wall of the vascular lesion repair device tube body 100 .

[0029] The arc-shaped hole 110 includes a first hole section 111 and a second hole section 112 that are interconnected. The ends of the first hole section 111 and the second hole section 112 that are away from each other respectively penetrate the inner wall of the vascular damage repair device tube body 100; the first hole section 111 is located at the end of the second hole section 112 away from the negative pressure suction device 400, and the end of the first hole section 111 that penetrates the inner wall of the vascular damage repair device tube body 100 is perpendicular to the inner wall.

[0030] Better yet, a V-shaped limiting groove 120 is formed on the inner wall of the vascular damage repair device tube body 100 and located at the end of the first hole section 111 away from the second hole section 112. Before clamping, the abutting portion 240 of the titanium clip 200 abuts against the limiting groove 120.

[0031] Furthermore, before the driver controls the titanium clip 200 to clamp, the first clamping portion 210 and the second clamping portion 220 are located within the arc-shaped hole 110 on their respective sides near the clamping opening 230, and the clamping opening 230 has the same inner diameter as the vascular lesion repair device tube 100. Furthermore, after the vascular lesion repair device tube 100 covers the bleeding point and aspirates the blood, if the bleeding point is determined to be within the vascular lesion repair device tube 100, by setting the clamping opening 230 and the inner diameter of the vascular lesion repair device tube 100 to be the same, the titanium clip's clamping range can be expanded as much as possible, thereby covering the bleeding point.

[0032] The driving assembly 300 passes through the two arc-shaped holes 110 and drives the titanium clip 200. When the titanium clip 200 opens under the action of elasticity, the abutment portion 240 abuts against the end of the second hole section 112. When entering the patient's body, the titanium clip 200 can be limited by the two second hole sections 112. It should be noted that during the operation, even if the titanium clip 200 falls, because the vascular lesion repair device tube body 100 always maintains a negative pressure suction state, and the titanium clip 200 is located at the tube mouth position of the vascular lesion repair device tube body 100, if the titanium clip 200 falls, it can be discharged from the body of the vascular lesion repair device tube body 100 and will not enter the blood circulation in the blood vessel.

[0033] The drive assembly 300 includes a connecting tube 310 located within the vessel repair device body 100. The connecting tube 310 has two taps formed on the end near the titanium clip 200. Each tap is connected to a branch tube 320. The end of each branch tube 320, distal from the connecting tube 310, is inserted into the arcuate hole 110, and the branch tubes 320 are fixedly connected to the arcuate hole 110. The taps and branch tubes 320 are fixedly connected.

[0034] A rubber column 330 slides within each branch tube 320, its inner wall abutting against the inner wall of the branch tube 320. A driver is connected to the end of the connecting tube 310, away from the branch tube 320, to inject liquid into the connecting tube 310. The driver uses the liquid to provide hydraulic pressure, forcing the rubber column 330 to slide out of the arcuate hole 110 and compress the titanium clip 200. After clamping and hemostasis, the rubber column 330 separates from the titanium clip 200, while the titanium clip 200 remains clamped and hemostatic.

[0035] The driver includes an external tube 340 and a syringe 350. A mounting hole is defined in the sidewall of the vascular repair device body 100, distal to the titanium clip 200. The outer wall of the external tube 340 is sealed and fixedly connected to the mounting hole. One end of the external tube 340, which extends into the vascular repair device body 100, communicates with the connecting tube 310, while the other end communicates with the outlet of the syringe 350.

[0036] The present invention provides a laparoscopic vascular damage repair device. During thoracic surgery, when a vascular damage is found, the vascular damage repair device tube body 100 is inserted into the patient's body for negative pressure suction, and the vascular damage repair device tube body 100 is adjusted to a suitable position to suck away the bleeding. When there is no blood oozing out of the periphery of the vascular damage repair device tube body 100 and all the bleeding is sucked out by the vascular damage repair device tube body 100, it can be determined that the vascular damage repair device tube body 100 completely covers the bleeding points. Liquid is injected into the connecting tube 310 through the syringe 350, and pressure is applied to the rubber column 330 in the branch tube 320 through hydraulic pressure, so that the rubber column 330 slides outward. During the sliding process, it presses against the abutment part 240 of the titanium clip 200, so that the titanium clip 200 clamps the vascular damage port to achieve the purpose of hemostasis. This method combines the vascular rupture repair device tube body 100 and the titanium clip 200, so that the structure can not only perform negative pressure suction on bleeding, but also assist in finding the bleeding point, and can clamp and stop bleeding at the same time, and reduce the number of instruments entering the patient's body, making it convenient to operate at positions with tricky angles or that cannot be directly exposed, thereby improving the convenience of the operation and reducing the learning curve for surgeons to learn hemostasis.
