Problems solved by technology

However, the existing support members in this technical field, such as CN202235776, CN2699849, etc., all have a common defect: before the support member is implanted into the bone cavity, its size cannot be reduced by deformation, so as to pass through a smaller wound
Due to the existence of this defect, the installation operation of the existing femoral head support components will inevitably open an incision suitable for the minimum passing size of the support components, so the technical effect of "minimally invasive" cannot be achieved

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] The special anti-collapse insertion frame for the expansion-type femoral head of the airbag is composed of the air nozzle 01, the elastic cord 02, the airbag 03, the vertical rib 04, the flat rib 05 and the end shell 06. Wherein, the vertical rib 04, the flat rib 05 and the end shell 06 are made of nickel-titanium alloy. The end shell 06 is a pair of spherical crown-shaped shells arranged up and down. On the edge of each end shell 06, there are multiple flat ribs 05 hinged with the end shell 06. The multiple flat ribs 05 are along the edge of the end shell 06. The circumference is evenly distributed, and the extension line of the center line of each flat rib 05 intersects the axis line of the end shell 06 . There is a vertical rib 04 integrated with the flat rib 05 on each flat rib 05, and the cross section of the combination of the flat rib 05 ...

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 [0001] The invention relates to the field of medical devices, in particular to a special anti-collapse implantation frame for an airbag-expandable femoral head. Background technique [0002] In the prior art, when treating bone collapse caused by necrosis of the femoral head, it is necessary to implant a support member into the bone cavity. In the operation of implanting the support member into the bone cavity, minimally invasiveness is an important criterion for measuring the level of operation. However, the existing support members in this technical field, such as CN202235776, CN2699849, etc., all have a common defect: before the support members are implanted into the bone cavity, they cannot be deformed to reduce their size so as to pass through smaller wounds. Due to the existence of this defect, the installation operation of the existing femoral head support components will inevitably open a wound that is compatible with the minimum passing size of the ...
