Abstract
The invention relates to the technical field of medical apparatus and instruments, in particular to an air sac expansible and extensible anti-collapse implantation framework special for caput femoris. The air sac expansible and extensible anti-collapse implantation framework special for the caput femoris is composed of an air nozzle, elastic strings, an air sac, vertical ribs, flat ribs and end shells. The vertical ribs, the flat ribs and the end shells are made of nickel-titanium alloy. The end shells are a pair of shell bodies. The shell bodies are vertically arranged and in a spherical shape. The plurality of flat ribs hinged with each end shell are arranged on the edge of each end shell. The lower end of each flat rib hinged with the end shells arranged above the each flat rib is hinged with the upper end of each flat rib arranged below the each flat rib. According to the air sac expansible and extensible anti-collapse implantation framework special for the caput femoris, the air bag is adopted to appropriately adjust the appearance of the whole framework, and therefore before the framework enters an inner cavity of the caput femoris, and the effective passing size of the framework reaches the minimum. Due to the technical advantage, sufficient guarantee is provided for achieving a minimally invasive effect during a framework implantation operation.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of air bag and expand and stretch the special-purpose collapse of formula femoral head and insert framework.
Background technology
When prior art is produced the bone that causes and is subsided because of femur head necrosis in treatment, need to be with a supporting member implantable bone inner chamber.In the operation with supporting member implantable bone inner chamber, Wicresoft is a major criterion of weighing the operation level.And the existing supporting member of the art, such as CN202235776, CN2699849 etc., a common defective is all arranged: supporting member can't dwindle its size by deformation before the implantable bone inner chamber, so that pass through from less wound.Due to the existence of this defective, the installation of existing femoral head supporting member operation all inevitably will be left the wound that the minimum with supporting member adapts by size, therefore can't reach " Wicresoft " this technique effect.
Summary of the invention
The present invention is for solving the deficiencies in the prior art, providing a kind of can significantly dwindle its minimum and pass through size before installation, can return to original size again after being installed to bone cavity, expanding with the air bag of Wicresoft's effect of reaching operation and stretch the special-purpose collapse of formula femoral head and insert framework.
The scheme that solves the technology of the present invention problem is:
The air bag expansion is stretched the special-purpose collapse of formula femoral head and is inserted framework, is made of valve, stretch cord, air bag, stud, flat muscle and end housing.Wherein, the material of stud, flat muscle and end housing is Nitinol.End housing is a pair of housing setting up and down, domed, and a plurality of flat muscle hinged with end housing are arranged on the edge of each end housing, and a plurality of flat muscle distribute along the even circumferential of end housing, and the extended line of the centrage of every flat muscle is all crossing with the axial line of end housing.Having with flat muscle on each flat muscle is holistic stud, and the cross section of the coalition of flat muscle and stud is the T font.The upper end of the flat muscle of the lower end of the flat muscle that the end housing of each root and top is hinged and its below is hinged.Stretch cord is the rope body of the latex material of a closure.The axle of the hinged place of the two flat muscle that often are hinged has a horizontal through hole, and described stretch cord all passes this horizontal through hole and horizontal through hole is bonding therewith.
Bonding pad is the hard plastic sheet of a circle, and the upper surface of bonding pad is bonding with the bottom surface of the end housing that is positioned at the top.Be provided with an air bag between described two end housings, air bag is provided with valve, and the end face of air bag has a circular hole, and the edge of this circular hole and the lateral edges of bonding pad are bonding is an integral body.
Adopt such scheme, can reach following effect:
1. when the present invention is in idle state, be not filled with air in air bag, distance between two end housings is the thickness sum of bonding pad and air bag, whole device is an oblate framework, at this moment, only need to offer a width greater than the gap of the vertex distance of two end housings on the bone cavity wall, just whole device can be sent in bone cavity.Then pass described gap and insert in described valve airbag aeration with air tube, expansion along with air bag, distance between two end housings is depressed continuous increase on the top of air bag, and the diameter of the excircle that is made of the pin joint of the flat muscle that is hinged constantly dwindles, whole device by original oblateness gradually to spherical transition.After inflation finished, the coalition of two bonding pads of the present invention and a plurality of flat muscle and stud had played supporting role at vertical direction and horizontal direction to the bone that subsides respectively.
2. because the present invention adopts air bag, the profile of whole device is in time regulated, therefore can be before entering bone cavity, what make device effectively reaches minimum by size, and can expand significantly its volume after entering bone cavity, this technical characterictic is " Wicresoft " effect that realizes the member implantation surgery, and sufficient assurance is provided.
3. flat muscle in the expansion process of air bag, had both needed to possess good bending rigidity, can not also will consider cost of manufacture to the air bag injury again, and can not materials too much, this be one group of insoluble contradiction of those skilled in the art.And the present invention is combined into flat muscle and stud the member that cross section is the T font, this shape not only improved member vertically and the bending rigidity of horizontal direction, but also the contact area that has increased member and air bag avoided also having saved cost of manufacture because of the excessive damage to air bag of pressure.
due to the sealing air bag in expansion process, its each particle is all constantly moving, therefore, air bag should be bonded between two end housings, avoid again bonding position to tear in expansion process, this is also the insoluble technical problems of those skilled in the art, the present invention is owing to being provided with bonding pad, make the bottom surface of the upper surface of bonding pad and end housing bonding, the side of end housing and air bag end face offer bore edges bonding, due to air bag in expansion process, the particle position of the junction, edge of it and hardened member can not change, bonding pad has played the effect of bridge in the combination with air bag and end housing, make both combinations well.
5. the present invention is designed to domed housing with end housing, compares with the cylindrical of prior art, and the effective contact area with the chamber wall in capital bone cavity is larger, makes the point of application of support force distribute more even.
