Description

Intravascular auxiliary opening device for complex interventional operation

Technical Field

The application relates to the technical field of minimally invasive vascular interventional operations, in particular to treatment of complex lesions in interventional operations, and particularly provides an intravascular auxiliary opening device capable of being applied to the complex interventional operations.

Background

The cardiovascular and cerebrovascular minimally invasive interventional therapy is a main treatment means for cardiovascular and cerebrovascular diseases. Compared with the traditional surgery, the method has the obvious advantages of small incision, short postoperative recovery time and the like. The cardiovascular and cerebrovascular intervention operation is a treatment process by a doctor manually sending the catheter, the guide wire, the bracket and other instruments into a patient.

For some patients with serious lesions, the blood vessels are seriously blocked and even completely blocked, and doctors often have difficulty in opening the lesion parts in the treatment process of using the guide wire catheter, so that the patients cannot be effectively treated.

Chinese patent No. CN212326522U discloses an auxiliary puncture balloon for coronary intervention diagnosis and treatment, which is divided into three parts, namely a continuous head section, a body section and a tail section; the head section and the body section are straight, and the head section is provided with an expandable balloon structure; the front part of the tail section is a conical control section, and the surface of the tail section is provided with grid lines; the rear part of the tail section is of a Y-shaped bifurcation structure, so that a pressure channel port and a guide wire channel port are formed; the pressure channel and the guide wire channel which are mutually independent extend from the tail section to penetrate through the head section and the body section; the pressure channel and the guide wire channel are parallel to each other, and are separately guided to the respective pressure channel port and guide wire channel port in the tail section; the pressure port is used for connecting a pressure pump, and the guide wire port is used for connecting a Y valve. Although the auxiliary puncture saccule disclosed in the document can ensure that the guide wire enters the occlusion section in the middle of the knife-cut sample occlusion proximal end fibrous cap, replaces the current micro-catheter or the conical head end saccule to directly control the guide wire to enter the occlusion section, can be better and tightly attached to the knife-cut sample occlusion proximal end fibrous cap, ensures that the guide wire enters the occlusion section from the inside of a vascular structure, and improves the efficiency and success rate of operation.

The Chinese patent No. 111588442A discloses a balloon auxiliary inferior vena cava puncture needle and a use method thereof, when the balloon auxiliary inferior vena cava puncture needle is used, a catheter fixing tube is held firstly, and the supporting property of a guide wire is utilized to drive the catheter fixing tube to puncture the internal parts of jugular vein and inferior vena cava; when the balloon mechanism at the top end of the catheter mechanism reaches the front end of the inferior vena cava occlusion section, the guide wire is drawn out; at the moment, physiological saline and contrast agent are injected into the balloon through the balloon injection tube and the injection cavity, the inferior vena cava is spread, a certain cavity is formed between the inferior vena cava and the inferior vena cava occlusion section by utilizing the supportability of the balloon, and the inferior vena cava can be changed by a certain angle; then bending the puncture head and the puncture needle point to a certain angle, and holding the pointer to enable the puncture needle rod, the puncture head and the puncture needle point to reach the occlusion section of the inferior vena cava through the hollow catheter, so that the puncture needle point is utilized for puncture and opening. Although the balloon-assisted inferior vena cava puncture needle disclosed in the patent document can effectively support the upper vena cava and the lower vena cava above a lesion part, improve the success rate of puncture of the inferior vena cava blocking section, avoid puncturing the vessel wall and improve the safety, but the balloon-assisted inferior vena cava puncture needle has the process of extracting a guide wire in the use process, when the balloon is used for expanding the inferior vena cava part, the puncture head and the puncture needle point are bent to a certain angle, the hand-held pointer is used for puncturing and opening by using the puncture needle point, the process needs to extract the guide wire, an operation instrument is replaced, the guide wire is also needed to be inserted back when the opening blocking part is continuously pushed backwards, and the operation method is repeated in the opening process, so that the problems of inconvenience in operation and low operation efficiency exist.

The Chinese patent No. 111150924A discloses a new clinical intervention diagnosis and treatment vascular occlusion structure and an opening method, and the process is as follows: identifying vascular occlusion lesions by an operator by contrast; pushing the system until the proximal end of the vascular occlusion lesion; the connecting inflatable device is arranged at the proximal end of the cavity channel; the balloon is fixed at the proximal end of the vascular occlusion lesion after being inflated; feeding the guide wire through the cavity, and pushing the guide wire until the tail end of the guide wire reaches the vascular occlusion lesion position; if the vessel occlusion lesion is longer, the air in the balloon can be released, the balloon is continuously pushed forward, and the operation is repeated. Although the clinical intervention diagnosis and treatment vascular occlusion structure and the opening method provided by the patent document simplify the clinical intervention operation flow and improve the success rate of occlusion vascular opening, in the guide wire pushing process, the guide wire passes through the saccule cavity, the guide wire is manually pushed, the force of pushing the guide wire by the rear end exists in the pushing process, the force is transmitted to the front end of the guide wire, more loss is caused, the force of the front end of the guide wire actually acting on a lesion plaque is insufficient, the guide wire is easy to deform, and the air bag is easy to slip.

Therefore, the whole proposal disclosed in the patent document has the problems that the pushing force is lost in the pushing process of the guide wire, the supporting force of the front end of the guide wire is insufficient, the balloon is easy to slip, and the blocking plaque cannot be opened.

Further, the inventors have realized in clinical practice that the present complex interventional procedures have problems in essentially the following ways during the procedure:

(1) The guide wire used at present is an elongated flexible object, and the doctor holds the part outside the human body and can reach the front end of the guide wire to act on the disease position through a long distance, so that the guide wire is easy to deform in the pushing process, the supporting force of the front end is insufficient, and the blocked plaque cannot be opened.

(2) The force of doctor at rear end propelling movement seal wire, the transmission to seal wire front end in-process, the loss is more, leads to seal wire front end actual effect not enough on the dynamics of lesion plaque for the seal wire can't pass through the plaque.

(3) The guide wire head is easy to deviate in the direction in the process of actually puncturing plaque, so that the guide wire penetrates into the wall of a blood vessel and even penetrates through the blood vessel, and surgical accidents are caused.

(4) At present, although some supporting force can be improved by the devices such as the microcatheter and the like, the supporting force is limited because the devices are flexible surgical consumable materials, the plaque is generally hard, the required supporting force is large, and the prior surgical instrument cannot meet the surgical requirement.

(5) At present, the treatment process for opening the plaque in the blood vessel is complicated, various consumables need to be replaced, the use is inconvenient, and the operation efficiency is low.

Therefore, a new solution is needed to solve the problems existing in the prior art.

Balloon catheter systems currently used in cardiovascular and cerebrovascular interventional procedures are those in which a flexible and bendable guidewire (typically made of a metal alloy) is passed through the lumen of the balloon catheter. The guide wire is used for guiding the balloon catheter to a position to be treated in a blood vessel, the distal end of the catheter (namely, the part with the balloon) is placed at a target position in the blood vessel, the proximal end of the catheter is left outside the body, and an interface is arranged on the proximal end catheter and used for being connected with an inflator pump; this interface is typically of standardized design to ensure a sealed connection between the inflator and the conduit. Although the existing balloon has the function of dilating blood vessels, the existing balloon also has the problems of slipping and incapability of opening when encountering hard plaque in blood vessels, in addition, the guide wire is arranged in the balloon catheter in a penetrating way, and when the balloon slips, the guide wire also deflects along with the balloon and cannot further open the blood vessels, so that the existing balloon catheter guide wire system has insufficient supporting force, the balloon cannot advance when encountering hard plaque, slipping occurs, the force acting on the guide wire cannot be accurately transmitted to the plaque, the force loss is serious, the guide wire is soft, and the guide wire is easy to deform under the condition that the guide wire cannot be pushed. Therefore, completing the opening of the occluded blood vessel in the current cardiovascular and cerebrovascular interventional operation is still an important problem to be solved urgently.

The puncture device 100 in the present application mainly includes a puncture needle 110, an external threaded rod 120 connected to the needle end of the puncture needle 110, and a guide wire 130 connected to the end of the external threaded rod 120, the guide wire 130 extending to the outside of the human body. The puncture needle 110 is a rigid cone-shaped needle body for directly contacting a portion inserted into plaque, and the puncture needle 110 is made of a metal material. The external threaded rod 120 arranged at the tail of the puncture needle 110 is used for being matched with the supporting part 200, so that stronger pushing force is improved, the guide wire 130 is provided with a pushing direction positioning function, the guide wire 130 is prevented from deviating and puncturing the vessel wall, the screwed external threaded rod 120 is prevented from retreating through the meshing function of threads, and the loss of pushing force is reduced.
