Abstract
The utility model discloses a membrane covered fabric body system for embolization of arterial aneurysm, which belongs to the field of medical instruments and includes a reticulate fabric body and a conveying system connected with the reticulate fabric body. After release, the fabric body is of a gourd-shaped double-layer sphere structure; the fabric body is flat at bottom; and the connection part of the fabric body and the conveying system are positioned inside the fabric body, that is, the connection is not protruded out of the fabric body. The inside surface or the outside surface of the fabric body is covered with a membrane. The membrane is made of polytetrafluoroethylene and the like. One layer of membrane or multiple layers of membranes is/are arranged. The fabric body is covered overall or partially, and the bottom part is required to be covered certainly. As compared with the fabric body without the membrane, the membrane-covered fabric body system can more effectively prevent blood from getting into the arterial aneurysm and further impacting the wall of the arterial aneurysm. More layers of membranes can lead to a more obvious effect. Meanwhile, as the inside of the fabric body is covered with the membrane, the grid on the surface of the fabric body can be produced to be relatively sloppy, the number of fabric silks of the fabric body can be reduced, and further, the contour of the fabric body can be reduced and the resistance to the fabric body during the conveying process can be lowered.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and more particularly, this utility model relates to a kind of novel aneurysmal overlay film knitted body of thromboembolism system that is used for.
Background technology
Aneurysm is a kind of common angiopathy.Instantly for how treating aneurysm, external doctor has brought into use netted knitted body to remove to carry out aneurysmal thromboembolism clinically.
People's such as A Tuluo patent (CN 102014769 A) has been set forth a kind of aneurysm embolization device of knitted body.But this kind device is difficult to the grid that it is surperficial and accomplishes very fine and close degree because its structural restriction, otherwise can cause excessive appearance profile and influence transportation performance.And its surface fine and close grid inadequately then can influence aneurysmal effect of embolization to a certain extent.
In view of the above about the deficiency of netted knitted body, need more preferably device of one of invention, neither can cause excessive appearance profile, can improve again because its surface mesh deficiency on the curative effect brought of densification inadequately.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, and a kind of novel aneurysmal overlay film knitted body of thromboembolism system that is used for is provided.
The purpose of the present utility model is achieved through the following technical solutions:
A kind of for the aneurysmal overlay film knitted body of thromboembolism system, comprise netted knitted body and the induction system that is connected with knitted body, described knitted body is double-deck sphere structure after discharging, the knitted body bottom flat, and place knitted body inside with the coupling part of induction system, namely this coupling part is not projected into the knitted body outside.Overlay film on the interior or outer body surface of described knitted body.
The purpose of the present utility model can also be achieved through the following technical solutions:
Described knitted body overlay film is one or more layers.Described knitted body film covering method adopts the binding agent with compatibility to stick on the body surface of knitted body, or adopts medical line that film is fixed on the knitted body body surface, can also adopt the method for mechanical grip to be fixed on the body surface of knitted body.Described knitted body overlay film position is that all standing or part cover, but must cover the knitted body bottom.
Compared with prior art, the utlity model has following beneficial effect:
Because the knitted body overlay film is the bottom overlay film at least and cover the aneurysm eck fully, for the knitted body that does not have overlay film, can more effectively stop blood to enter in the aneurysm tumor wall is impacted.Rete is more many, and this effect is more obvious.Simultaneously, because overlay film in the knitted body, it is laxer relatively to allow grid with the knitted body surface to manufacture, and can reduce the number of the braided wires of knitted body like this, thereby reduce its appearance profile, and reduce the resistance that it runs in course of conveying in vivo.

The specific embodiment
Below in conjunction with drawings and Examples essentiality content of the present utility model is described in further detail:
As shown in Figure 1: a kind of for the aneurysmal overlay film knitted body of thromboembolism system, comprise netted knitted body 1 and the induction system 3 that is connected with knitted body 1, after discharging, knitted body 1 is double-deck sphere structure, knitted body 1 bottom flat, and place knitted body 1 inside with the coupling part of induction system 3, namely this coupling part is not projected into knitted body 1 outside.
Shown in Fig. 2-1 and Fig. 2-2, Fig. 3-1 to Fig. 3-4: overlay film 2 on the interior or outer body surface of knitted body 1.Knitted body 1 overlay film 2 is one or more layers.Knitted body 1 overlay film 2 methods adopt the binding agent with compatibility to stick on the body surface of knitted body 1, or adopt medical line that film 2 is fixed on knitted body 1 body surface, can also adopt the method for mechanical grip to be fixed on the body surface of knitted body 1.Knitted body 1 overlay film 2 positions are that all standing or part cover, but must cover knitted body 1 bottom.
Embodiment one: utilize the non-sidewall aneurysm of knitted body system thromboembolism tremulous pulse.As shown in Figure 1, a kind of novel aneurysmal overlay film knitted body of thromboembolism system that is used for comprises the netted knitted body 1 and the induction system 3 that is connected with knitted body 1 of overlay film 2.Sheath pipe 4 and the microtubular 5 that is enclosed within outside the sheath pipe 4 in when implementing operation, also the overlay film knitted body need being compressed in.Microtubular 5 enters aneurysm 7, and whole film covering 2 knitted body systems advance at microtubular 5 inner chambers subsequently, arrives aneurysm tumor mouth until its far-end.Keep sheath pipe 4 motionless, promote induction system 3 forward, make overlay film 2 knitted bodies 1 in aneurysm, move gradually.In this process, overlay film 2 knitted bodies 1 can constantly expand automatically.Along with whole film covering 2 knitted bodies 1 are pushed out outside the sheath pipe 4, overlay film 2 knitted bodies 1 will be released in the aneurysm 7 fully.Start then be connected the induction system near-end free instrument 6, make the junction point fusing of induction system 3 and overlay film 2 knitted bodies 1, so induction system 3 is separated with overlay film 2 knitted bodies 1.Induction system 3 and sheath pipe 4 are withdrawn to outside the patient body, stay overlay film knitted body 1 in aneurysm 7 to make thromboembolism (referring to Fig. 4).These overlay film 2 knitted bodies 1 are lageniform double-deck sphere structure, are conducive to reduce the impact to aneurysm 7 tops.Overlay film 2 knitted bodies 1 bottom flat, and be rolled in overlay film 2 knitted bodies 1 inside with the coupling part of induction system 3 by receipts, namely this coupling part is not projected into the knitted body outside.This structure is conducive to knitted body bottom and is identical with carrying a tumor blood vessel, and does not fall into the flow direction of carrying tumor blood vessel internal interference blood flow with the coupling part of induction system 3.Before instrument 6 was freed in startup, induction system 3 can not separated with knitted body 1.Find the knitted body system that needs to adjust the position or change other specifications in the process of aneurysm 7 if discharge knitted body 1, the induction system 3 of can directly dropping back, thereby knitted body 1 is recovered in the sheath pipe 4 again, gets final product by above step operation again after readjusting the position of apparatus or changing knitted body 1 system of appropriate size.
