Description
Technical field
The present invention relates to operation shadowless lamp technical field, and in particular to a kind of shadowless lamp sterilization of any angle installing/dismounting
Handle.
Background technology
The rotation or movement of operation class shadowless lamp all realize that handle jacket is doctor or nurse in hand by handle
One of device that must be operated during art；In order to avoid germ contamination, handle jacket is needing high-temperature steam to disappear using front and rear
Poison processing；Sterile handle overcoat must be easily installed or dismantle, and easily installation Post operation is easily disassembled before surgery, and ensures
Liquid is not easily accessible inside it in operation.Existing sterile handle generally comprise handle jacket, inner handle support, button, neck and
The devices such as spring, it is before handle is installed, it is necessary to which handle jacket, this single angle installation can just be installed by finding groove position accurately
Or the structure application of dismounting is inconvenient, and the problem of blood and body fluid enter its internal structure in surgical procedure be present, and
Loss problem of the high-temperature sterilization to handle jacket.
The content of the invention
The present invention is intended to provide a kind of shadowless lamp sterile handle of any angle installing/dismounting, to realize handle any angle
Installation, dismounting, avoid blood and body fluid in operation from entering handle inner, be easy to decontamination cycle to use.
Technical scheme is as follows：
A kind of shadowless lamp sterile handle of any angle installing/dismounting, includes handle jacket, push rod and inner handle support；Push rod
The tail end of handle jacket is arranged on by way of interference fit, push rod has leading section, and the rear of leading section is provided with annulus
The spacing back-up ring of shape；Inner handle support is placed in handle jacket, and the rear end of inner handle support is with by bearing pin connection and symmetrically
There is the buckle slot engaged with the spacing back-up ring of annular on push rod the limit fastener of distribution, the lower end of limit fastener, limit fastener
There is recess in outside, and inner handle support also has rubber o-ring, and rubber o-ring is stuck in the indent of limit fastener.
Handle jacket uses PPSU macromolecule engineering plastics.
The inner chamber rear portion of handle jacket has limiting stand, to limit the position of inner handle support axially backward.
The width of buckle slot is more than the width of spacing back-up ring, to hold the axial movement of push rod certain size.
The medial surface of limit fastener is inclined plane, the radial dilatation with the reach with push rod leading section, departs from buckle slot
Spacing back-up ring.
In the present invention, according to handle jacket PPSU macromolecule engineering plastics performances, handle jacket push rod is installed with external force
In handle casing neck, interference fit mounting means ensures that handle jacket push rod will not fall off.Sterilize and complete in handle jacket
Afterwards, inner handle support can be inserted from any angle, the limit fastener of inner handle support can block in the presence of rubber o-ring
The spacing back-up ring of the annular of push rod in handle jacket, ensure difficult for drop-off；When disassembled, handle jacket, thumb press top are held
Bar makes push rod move forward, and the leading section extruding limit fastener introversion inclined-plane of push rod is so that buckle slot departs from spacing back-up ring.
The beneficial effects of the present invention are：The present invention can any angle installation or removal handle jacket, facilitate application；Hand
The encapsulation of handle overcoat ensures that blood and body fluid will not enter its internal structure in surgical procedure；Handle jacket PPSU macromolecules
Engineering plastics performance guarantee will not lose in high-temperature sterilization.
Brief description of the drawings
Below according to accompanying drawing, the present invention will be described：
Accompanying drawing 1 is the structural representation of handle jacket in the present invention；
Accompanying drawing 2 is the structure decomposition figure of inner handle support in the present invention；
Accompanying drawing 3 is mounting structure schematic diagram of the invention；
In figure, 1 handle jacket, 1-1 limiting stands, 2 push rods, the spacing back-up rings of 2-1,2-2 leading sections, 3 inner handle supports, 4 limiting cards
Button, 4-1 buckle slots, 4-2 recesses, 4-3 pin-and-holes, 4-4 bearing pins, 5 rubber o-rings.
Embodiment
With reference to specific embodiment, the present invention is further illustrated.
Embodiment 1
Include handle jacket as illustrated in the accompanying drawings from 1 to 3 for a kind of embodiment of shadowless lamp sterile handle in the present invention, the embodiment
1st, push rod 2 and inner handle support 3；Push rod is arranged on the tail end of handle jacket by way of interference fit, and push rod has front end
Portion 2-2, the rear of leading section are provided with the spacing back-up ring 2-1 of annular；Inner handle support is placed in handle jacket, inner handle branch
The rear end of frame has and had and annular on push rod by bearing pin connection and symmetrical limit fastener 4, the lower end of limit fastener
The buckle slot 4-1 of spacing back-up ring engaging, there is recess 4-2 on the outside of limit fastener, inner handle support also has rubber o-ring 5, rubber
Glue O-ring is stuck in the indent of limit fastener.
The spacing back-up ring of above-mentioned cirque structure can ensure that to be engaged from any angle with limit fastener installation.
Handle jacket uses PPSU macromolecule engineering plastics.The inner chamber rear portion of handle jacket has limiting stand, with restriction
The position of handle bracket axially backward.The width of buckle slot is more than the width of spacing back-up ring, to hold the axial direction of push rod certain size
It is mobile.The medial surface of limit fastener is inclined plane, the radial dilatation with the reach with push rod leading section, departs from buckle slot spacing
Back-up ring.
