Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a special vascular endothelium flusher for minimally invasive conditions. Background Art
[0002] In today's rapidly evolving surgical landscape, the transition from complex surgeries to minimally invasive procedures has become a mainstream trend, offering advantages such as reduced trauma and improved recovery. Vascular anastomosis in minimally invasive settings, a key breakthrough in this field, faces the challenge of efficiently completing anastomosis within limited space and preventing thrombosis.
[0003] During vascular anastomosis, precise administration of anticoagulant flushing fluid is a key step in preventing thrombosis. However, current minimally invasive surgical systems, such as laparoscopy, lack flushing equipment specifically designed for this procedure. Intra-abdominal vascular anastomosis sites are hidden, requiring deep access to the body for operation. Traditional flushing methods are difficult to directly and effectively apply to the anastomotic surface, increasing the difficulty of the procedure and the risk of complications.
[0004] Therefore, in view of the problems existing in the prior art, it is necessary to design a technical solution to solve the above problems. Utility Model Content
[0005] In order to solve the technical problems existing in the prior art, the purpose of the present utility model is to provide a minimally invasive special vascular endothelial flusher to solve the above technical problems.
[0006] In order to achieve the purpose, the utility model adopts the following technical solutions:
[0007] A minimally invasive dedicated vascular endothelial flusher, comprising:
[0008] The external irrigation tube can pass through the patient's abdominal wall and penetrate deep into the patient's abdominal cavity;
[0009] an inner flushing tube, disposed within the outer flushing tube, with one end extending out of the outer flushing tube to connect to an external flushing fluid, and the other end passing through the outer flushing tube to output the flushing fluid into the patient's abdominal cavity; and
[0010] The flushing head is connected to the inner flushing tube and is used to output the flushing fluid transported by the inner flushing tube to the vascular endothelium of the patient's abdominal cavity for flushing.
[0011] Preferably, the end of the flushing head is bent.
[0012] Preferably, the flushing head is made of soft material.
[0013] Preferably, the inner flushing tube is a hose made of soft material and can be deformed and bent.
[0014] Preferably, the outer flushing tube is a hard tube made of hard material.
[0015] Preferably, the outer flushing tube is further provided with a connection portion for an external flushing liquid injection device.
[0016] Preferably, the connecting portion is provided at an end portion of the flushing inner tube where the flushing head is not provided.
[0017] Preferably, the connecting portion is an interface whose shape matches that of the syringe outlet.
[0018] This utility model features a minimally invasive, specialized endovascular irrigator with a sophisticated design. It allows for the infusion of irrigating fluid from outside the body, which is then dripped directly onto the surface of the vascular anastomosis within the body, achieving a precise and efficient irrigating process. This design not only addresses the difficulty of traditional irrigating methods in reaching deep anastomoses, but also significantly improves the irrigating effect and reduces the risk of thrombosis. Furthermore, the curved design of the irrigating head prevents damage to blood vessels while inside the body. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figures 1 to 3As shown, a minimally invasive special vascular endothelial flusher includes an outer flushing tube 1, an inner flushing tube 2 and a flushing head 3. The outer flushing tube 1 is provided with a cavity for the inner flushing tube 2 to pass through. The outer flushing tube 1 is used to enable the flushing end of the flusher to smoothly extend into the patient's abdominal cavity. The inner flushing tube 2 is used to transport flushing fluid. The flushing head 3 is connected to the end of the inner flushing tube 2 and is used to output flushing fluid for blood vessel flushing.
[0030] The outer flushing tube 1 described in the present invention is a hard tube that usually has a certain hardness, or can maintain its original state and is not easily deformed by force. It is usually used to penetrate the patient's skin and extend into the patient's abdominal cavity when in use. For example, the outer flushing tube 1 can penetrate the patient's abdominal wall 4 through an incised wound.
[0031] The outer flushing tube 1 is a tubular structure, and its inner diameter is much larger than that of the inner flushing tube 2, allowing the inner flushing tube 2 to move freely therein, making it convenient for the inner flushing tube 2 to extend into the patient's abdominal cavity to deliver flushing fluid for flushing.
[0032] The flushing inner tube 2 described in the present invention refers to a pipeline usually provided for liquid transportation, which is generally a flexible hose that can be bent at will. When in use, one end is usually connected to the injection device 6 to inject flushing liquid, and the other end outputs the flushing liquid for flushing.
[0033] Preferably, the outer irrigation tube 1 is a hard tube made of a hard material. For example, the outer irrigation tube 1 is made of stainless steel, has a diameter of approximately 3 mm to 5 mm, and a length of approximately 10 cm to 15 cm. Alternatively, in some other embodiments, the outer irrigation tube 1 can also be a hard plastic tube.
[0034] Preferably, the outer flushing tube 1 is a straight tube, which facilitates the movement of the inner flushing tube 2 therein.
[0035] Preferably, the inner pipe 2 is made of a soft material. For example, the inner pipe 2 is made of a soft material such as latex, silica gel, etc.
[0036] The flushing head 3 is connected to the end of the flushing inner tube 2. One end of the flushing head 3 is a liquid outlet 31, and the other end is connected to the flushing inner tube 2, so that the flushing liquid input into the flushing inner tube 2 can be discharged through the liquid outlet 31 of the flushing head 3 for flushing.
[0037] Similarly, the flushing head 3 is made of soft material and has a smooth surface, so that even if the flushing head 3 directly contacts the vascular endothelium 5 during flushing, it will not damage the vascular endothelium 5. For example, the flushing head is made of latex, silicone, etc.
[0038] Furthermore, the end of the flushing head 3 is also provided with a certain curvature to prevent the flushing head 3 from directly poking the vascular intima 5 and causing damage to the vascular intima 5, and facilitates the flushing head 3 to flush deeply into the blood vessel cavity. Preferably, the end of the flushing head 3 is curved, and the curvature of the flushing head 3 exceeds 30 degrees.
[0039] Of course, in order to prevent the flushing head 3 from causing damage to the vascular endothelium 5, the end of the flushing head 3 can also be set to be arc-shaped.
[0040] Preferably, the flushing head 3 is adhesively connected to the flushing inner tube 2. Alternatively, in some other embodiments, the flushing head 3 and the flushing inner tube 2 can also be integrally formed.
[0041] Preferably, the size of the flushing head 3 is slightly smaller than the inner diameter of the flushing outer tube 1 , so that the flushing head 3 and the flushing inner tube 2 can be withdrawn from the flushing outer tube 1 at the same time.
[0042] The inner irrigation tube 2 also includes a connection portion 21, which allows the inner irrigation tube 2 to be connected to an injection device 6 (e.g., a syringe, a surgical irrigation water bag, etc.), so that the inner irrigation tube 2 can be connected to the irrigation fluid for irrigation. Preferably, the connection portion 21 is provided at the other end of the inner irrigation tube 2 that is not provided with the irrigation head 3.
[0043] Alternatively, in some other embodiments, a branch tube may be provided at the end of the inner flushing tube 2 where the flushing head 3 is not provided as a connecting portion 21 for connecting to an injection device 6 such as a syringe and a surgical flushing water bag.
[0044] The connecting portion 21 is configured as an interface at the end of the flushing inner tube 2. The interface is open at one end away from the flushing inner tube 2, and its diameter gradually decreases in the direction approaching the flushing inner tube 2. The diameter of the opening is slightly larger than the diameter of the syringe outlet, so that it forms a structure adapted to the syringe outlet (i.e., similar to a needle seat structure), which is convenient for connecting to a syringe or a surgical flushing water bag.
[0045] Alternatively, in some other embodiments, the connecting portion 21 may also be configured as a common joint structure in existing infusion tubes.
[0046] Preferably, the connecting portion 21 is glued to the inner flushing tube 2. Alternatively, in some other embodiments, the connecting portion 21 and the inner flushing tube 2 may be integrally formed.
[0047] The flushing process of the utility model device is as follows:
[0048] refer to Figure 3The patient lies on the bed. After the vascular anastomosis operation is performed on the abdomen, the outer flushing tube 1 is inserted into the body through the laparoscopic instrument. The inner flushing tube 2 and the flushing head 3 are passed through the outer flushing tube 1 and inserted into the arterial lumen, aligned with the anastomotic position of the vascular endothelium 5. Then, the injection device 6 is connected to the inner flushing tube 2 outside the body, and the flushing fluid is injected to clean the anastomotic position of the vascular endothelium 5.
[0049] The present invention features a minimally invasive, specialized endovascular irrigator (5), featuring a sophisticated design. It allows for the infusion of irrigating fluid from outside the body, which is then dripped directly onto the surface of the vascular anastomosis within the body, achieving a precise and efficient irrigating process. This design not only addresses the difficulty of traditional irrigating methods in reaching deep anastomoses, but also significantly improves the irrigating effect and reduces the risk of thrombosis. Furthermore, the curved design of the irrigating head (3) prevents damage to blood vessels while inside the body.
[0050] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
