Description
Technical field
This utility model relates to medical instruments field, and the spiral that particularly a kind of blood vessel is got involved the class apparatus pushes handle arrangement.Described blood vessel is got involved the class apparatus and is meant self-inflated intravascular stent, the vascular filter that adopts interventional therapy operative treatment angiopathy and is used for the treatment of cardiopathic stopper etc.
Background technology
The interventional therapy method of blood vessel kind disease is to be applied to a clinical new technique in recent years, its ultimate principle is the concrete condition according to blood vessel kind disease, with the corresponding treatment apparatus, such as intravascular stent, vascular filter and stopper etc., adopt conveyer device to import diseased region by blood vessel, and under the monitoring of X fluoroscopic apparatus, apparatus is discharged, thereby reach therapeutic purposes.
Adopt interventional therapy treatment blood vessel kind disease to be unable to do without dispensing device, having announced the patent No. such as, Chinese patent October 17 calendar year 2001 is " abdominal aortic aneurysm is by membrane support and conveyer device thereof " utility model patent of 00265484.9; Again such as, calendar year 2001 December to announce the patent No. on the 5th be " monolithic entity fork type hemangioma is by the membrane support transmitting system " utility model patent of 01210591.0; For another example, on May 7th, 2003 announcing the patent No. again is " abdominal aortic aneurysm is by the membrane support dispensing device " utility model patent of 02263040.6.Such scheme has disclosed research trend and the characteristics that blood vessel is got involved class apparatus dispensing device as the representative of intravascular stent, wherein, has comprised many technical conceives with practical value.But on the whole, what the class of blood vessel intervention in the past apparatus adopted basically is coaxial slidingtype propelling movement handle arrangement, and referring to illustrated in figures 1 and 2, promptly one of doctor holds lever 2 in the operation, and the another hands pushes apparatuses such as intravascular stent by pushing a slip.Though the propelling movement mode in this handle is simple, but also there are some drawbacks in the practical application, such as, first, because each gets involved the transporting resistance difference of class medical apparatus and instruments, the doctor has only by long-time use could obtain conveying, release experience, very high to doctor's requirement when therefore using, and often the grasp meeting of surgical experience and concrete action directly influences surgical effect; The second, because resistance is bigger in the propelling movement process, the doctor is difficult to the size and the rhythm of control propelling movement power, and the difficulty of operation is strengthened, and also causes operative failure easily, thereby has reduced the popularity rate of apparatus.In a word, existing dispensing device is because coaxial slidingtype pushes handle arrangement, and the size and the rhythm that push power are difficult to control, therefore bring some anthropic factors directly to influence surgical effect.
Summary of the invention
The spiral that this utility model provides a kind of blood vessel to get involved the class apparatus pushes handle arrangement, its purpose is that original coaxial slidingtype is pushed handle arrangement is improved to coaxial screw-pushing type handle arrangement, thereby solve the ubiquitous propulsive force size of dispensing device, the unmanageable problem of rhythm and position of the class of blood vessel intervention in the past apparatus, improve the controllability and the safety that push structure.
For achieving the above object, the technical solution adopted in the utility model is: the spiral that a kind of blood vessel is got involved the class apparatus pushes handle arrangement, comprise lever and push axle, lever is axially established through hole, push in the coaxial through hole that is arranged on lever of axle afterbody, rotary handle is set on the lever, described rotary handle is rotationally connected with lever on the one hand, and be axially arranged with position limiting structure between rotary handle and the lever, this rotary handle cooperates with the female thread external screw thread set with pushing the axle afterbody on the other hand, constitutes coaxial spiral with this and pushes structure.
Related content in the technique scheme is explained as follows:
1, this programme theme " spiral of blood vessel intervention class apparatus pushes handle arrangement " is that the general reference blood vessel is got involved spiral propelling movement handle arrangement in the class apparatus dispensing device, and blood vessel intervention class apparatus comprises self-inflated intravascular stent, vascular filter and is used for the treatment of cardiopathic stopper etc.
2, in the such scheme, a kind of member that described " rotary handle " is provided in a side of on the lever or is connected with lever, rotary handle and lever have following annexation: the first, rotary handle and lever are rotationally connected, and promptly rotary handle can rotate around axis relative to lever; The second, rotary handle axially can not move with respect to lever.
3, in the such scheme, rotary handle can have following change with respect to the position relation of lever:
(1), rotary handle can be located at the afterbody of lever, this design is the simplest, best results.
(2), rotary handle can be located at the front portion of lever.
(3), rotary handle can be located at the middle part of lever, this design is more complicated structurally.
4, in the such scheme, in transportation, push the unexpected motion of axle in order to ensure product, on the footpath of lever or rotary handle, be provided with the door bolt hole, be inserted with safety latch in this door bolt hole, the propelling movement axle outer rim of the head correspondence of safety latch is provided with tongue-and-groove, the safety latch head inserts in this tongue-and-groove, constitutes the safety latch lock construction with this.
5, in the such scheme, the described afterbody that pushes axle is provided with external screw thread, can adopt following dual mode: first kind is directly to process external screw thread at the afterbody that pushes axle; Second kind is that whole propelling movement axle is made two sections, and one section is common push shaft, and another section is a screw rod, by modes such as bonding or welding both is fixedly connected as overall structure then; The third is to have externally threaded metal or non-metallic casing, by modes such as bonding or welding both is fixedly connected as overall structure.
This utility model operation principle is: utilize a kind of screw-pushing type handle of screw mechanism principle design to replace in the past the pusher handle of common slip.According to the operation principle of screw pair, screw propulsion mechanism can promote big resistance under the very little situation of rotational resistance object advances, but and the size of propulsive force, rhythm easy adjustment, advance the position to control easily.
Because the technique scheme utilization, this utility model compared with prior art has following advantage:
1, this utility model is owing to adopt screw propulsion mechanism, and the size of propulsive force, rhythm can easily be controlled, and advances the position to control easily and regulate.
2, this utility model simple operation, safe, the operation easier when greatly reducing operation.
