Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a carotid shunt tube and a carotid artery surgical appliance.
Background
Carotid stenosis (carotidid stenosis) is one of the etiologies of the initiation of ischemic stroke. Carotid stenosis is mainly caused by atherosclerosis. Risk factors for carotid stenosis include hypertension, smoking, diabetes, hyperlipidemia, familial genetic factors, and the like. Although the good sites of carotid stenosis are the carotid sinus and the initial segment of the internal carotid artery, the detection rate of intracranial and extracranial carotid tandem lesions is increasing year by year. As shown in fig. 1, the carotid bifurcation combined total carotid (common carotid stenosis, CCA)/innominate arterial (innominate artery, IA) stenosis was 4.8% of total carotid stenosis. About 1/6 of patients with acute ischemic stroke present with intracranial (intracranial internal carotid artery, ICA) and extracranial tandem lesions of the carotid artery. The carotid cascade lesion is heavier than the stenosis of a single part, and the incidence rate of ischemic cerebral apoplexy of patients with the stenosis at the joint and bifurcation of the common carotid artery and the innominate carotid artery is up to 17% -30%.
Carotid endarterectomy (carotid endarterectomy) is currently considered the preferred surgical intervention as a surgical intervention to ablate the C1 segment of the carotid artery, the distal plaque of the common carotid artery and remove stenosis. Stenosis of the cervical total/innominate initial part, and stenosis of the C2 section and above of the internal carotid artery, because of great anatomical difficulty and great surgical trauma, vascular intervention is the first choice.
Carotid shunt (shunt) plays a very important role in carotid endarterectomy surgery, and can reduce cerebral ischemia time caused by carotid occlusion. When the existing carotid shunt is used, after a carotid sinus is incised by an operation, the inner end of a shunt neck is reversely inserted into the carotid artery, a priming shunt balloon is fixed, then the main end of the shunt neck is inserted into the common carotid artery, the priming shunt balloon is fixed, an open system realizes that arterial blood flows into the carotid artery from the common carotid artery through the shunt, and temporary blood perfusion of brain tissue at one side of the operation is established.
The prior art means can not simultaneously complete the carotid endangium peeling operation and the intervention treatment of carotid serial lesions (the positions comprise the proximal end of the common carotid artery, the distal end of the internal carotid artery and the intracranial segment of the internal carotid artery) through one vascular incision, and the lesions comprise stenotic lesions and neoplastic lesions such as aneurysms, or the risk of cerebral infarction caused by thrombus and debris falling in the operation is not effectively avoided. If the lesions of the initial segment of the common carotid artery and the lesions of the internal carotid artery are to be treated synchronously, additional direct-vision carotid artery puncture or establishment of a vascular access through femoral artery is often required, the risks of surgical trauma and vascular injury at the puncture part are increased, and a certain cerebral infarction risk is faced.

Fig. 2 is a schematic structural diagram of a carotid shunt according to an embodiment of the present invention.
As shown in fig. 2, the carotid shunt includes a shunt body 10 and a sheath 20. The outer walls of the tube bodies at the two ends of the diversion tube body 10 are provided with a balloon 11 and a balloon 12; one end of the sheath 20 is communicated with the middle part of the diversion pipe body 10 and is arranged at a preset angle with the diversion pipe body 10, and the other end of the sheath 20 is a free end; the carotid shunt further comprises balloon catheters 13 which are matched with the balloons 11 and the balloons 12, one end of one balloon catheter 13 is communicated with the balloon 11, the other balloon catheter 13 is communicated with the balloon 12, and the other end of each balloon catheter 13 is provided with a stop valve 14 for preventing the balloon from leaking gas.
The carotid shunt tube provided by the invention realizes the function of a conventional carotid shunt tube in carotid endarterectomy through a vascular incision, and then is sent into a guide wire, a catheter and various interventional instruments through a sheath tube, so that the serial lesions at the proximal end of the carotid artery or the distal end of the carotid artery can be treated synchronously.
According to an embodiment of the present invention, the sheath 20 is flexibly connected to the transfer tube 10. For example, the connection portion may be made of a flexible material, and the material may be appropriately selected with reference to the prior art, which will not be described herein.
According to an embodiment of the present invention, a transition pipe (not shown) is provided between the sheath 20 and the transfer pipe body 10.
According to an embodiment of the present invention, the transition pipe is disposed at a predetermined angle with respect to the diverting pipe body 10. When the sheath 20 is flexibly connected to the shunt body 10, the predetermined angle is preferably an oblique angle, for example, the predetermined angle is 30-45 degrees, more preferably 45 degrees, so that the interventional instrument can be delivered to the site of the tandem lesion. In some cases, the predetermined angle may be 90 degrees, considering the elasticity of the flexible material, as shown in fig. 2, and simply bent upward or downward in use to adaptively deliver the access instrument into the common carotid artery or the internal carotid artery.
According to an embodiment of the invention, a haemostatic valve is connected at the free end. Specifically, the free end of the sheath 20 is passed by an interventional instrument, and a hemostatic valve 22 is connected to the free end via a hose 21 to prevent blood from flowing out of the free end during surgery.
According to the embodiment of the invention, the inner wall of the diversion pipe body 10 is provided with scale marks, so that the position of the diversion pipe body stretching into the blood vessel can be conveniently determined.
According to the embodiment of the invention, the inner diameters of the diversion tube body 10 and the sheath tube 20 are not smaller than 5-6F, and further, the inner diameter of the transition tube is not smaller than 5-6F, so that the diversion tube is convenient for passing through interventional instruments such as a 0.014 inch-0.038 inch guide wire, a 5-6F catheter, a 5-6F balloon and a 5-6F bracket.
Fig. 3 is a schematic structural diagram of a carotid shunt according to another embodiment of the invention. Fig. 3 shows the number of the sheath pipes 20 as one and forms a predetermined angle with the transfer pipe body 10 in the obliquely downward direction, specifically, the predetermined angle is 45 degrees. Other technical details may refer to the embodiment shown in fig. 2, and will not be described here. It should be noted that, in the embodiment shown in fig. 3, for example, if the lower end of the shunt body 10 is placed in the common carotid artery, since the preset angle of the sheath 20 is set in the obliquely downward direction, the catheter is suitable for passing the interventional instrument into the internal carotid artery to treat the tandem lesion, and the interventional instrument cannot be delivered into the common carotid artery any more.
Fig. 4 is a schematic structural view of a carotid shunt according to another embodiment of the invention.
As shown in fig. 4, the number of the sheath pipes 20 is two, one sheath pipe forms a preset angle with the transfer pipe 10 in the obliquely downward direction, and the other sheath pipe 20 forms a preset angle with the transfer pipe 10 in the obliquely upward direction. Other technical details may refer to the embodiment shown in fig. 2, and will not be described here. Unlike the embodiment of fig. 3, by providing two sheaths 20, the interventional instrument can be delivered into the internal carotid artery through the sheaths 20 in the obliquely downward direction to treat the tandem lesion, and the interventional instrument can be delivered into the common carotid artery through the sheaths 20 in the obliquely upward direction to treat the tandem lesion at the same time, so that the surgical operation is further simplified, and the complications related to the surgical approach are reduced.
According to an embodiment of the present invention, the two sheaths 20 may communicate with the diverting tube body 10 through one transition tube each, so that the two sheaths 20 may not communicate with each other and may be spaced apart from each other. Of course, under suitable process, two sheath tubes 20 may also be in communication with the transfer tube body 10 through one transition tube, which is not limited in this regard by the present invention.
It should be understood that the carotid shunt in the embodiment of fig. 4 is schematically illustrated by using only two sheaths 20 as an example, and that more sheaths 20 may be provided as needed, which is not described herein.
Taking the carotid artery transfer tube in the embodiment of fig. 4 as an example, when the carotid artery transfer tube is used, after the carotid artery sinus is incised by an operation, one end of the carotid artery transfer tube is inserted into the carotid artery, the carotid artery transfer tube is fixed by inflating a balloon through a balloon catheter, then the other end of the carotid artery transfer tube is inserted into the common carotid artery, the carotid artery is fixed by inflating a balloon through a balloon catheter, arterial blood flows into the carotid artery from the common carotid artery through the carotid artery transfer tube, and temporary blood perfusion of brain tissue at one side of the operation is established.
Referring to fig. 1, in particular, when treating a carotid artery (CCA) tandem lesion (not shown in the figure), an interventional instrument is delivered through a sheath, and a temporary hemostatic forceps clamp one end of a carotid shunt tube, which is close to an Internal Carotid Artery (ICA), so as to avoid micro emboli and air entering the internal carotid artery along with blood flow during operation and reduce risk of postoperative cerebral infarction. When the internal carotid artery serial lesion is treated, the interventional instrument is sent into through the sheath tube, the temporary hemostatic forceps clamp one end of the internal carotid artery current transfer tube, which is close to the common carotid artery, so that the internal carotid artery blood flow is reversed in a short time, and the micro-emboli generated in the internal carotid artery lesion treatment process can flow along with the reverse blood flow, flow out of the body through the current transfer tube, and the risk of postoperative cerebral infarction is reduced.
Based on the same or similar inventive concept, the present invention also provides a carotid artery surgical instrument comprising a carotid shunt as described in the above embodiments and an interventional instrument delivered into the carotid artery via the sheath.
According to an embodiment of the invention, the interventional instrument comprises one or more of the following: guide wires, catheters, balloons and stents.
