Description

A kind of shadowless lamp sterile handle of any angle installing and dismounting

Technical field

The utility model is related to operation shadowless lamp technical fields, and in particular to a kind of shadowless lamp of any angle installing and dismounting Sterile 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 needs high-temperature steam to disappear afterwards before use Poison processing；Sterile handle housing must be easily installed or dismantle, easily easily disassembled after installation operation before surgery, and ensure Liquid is not easily accessible inside it in operation.Existing sterile handle generally comprise handle jacket, inner handle stent, button, card slot and The devices such as spring, 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 there are problems that in surgical procedure blood and body fluid into its internal structure and High-temperature sterilization is to the loss problem of handle jacket.

Utility model content

The utility model is intended to provide a kind of shadowless lamp sterile handle of any angle installing and dismounting, to realize that handle is arbitrary Installation, the dismounting of angle, avoid blood and body fluid in operation from entering handle inner, are used convenient for decontamination cycle.

The technical solution of the utility model is as follows：

A kind of shadowless lamp sterile handle of any angle installing and dismounting, includes handle jacket, mandril and inner handle stent； Mandril is mounted on the tail end of handle jacket by way of interference fit, and mandril has front end, and the rear of front end is provided with The limit stop ring of circular ring shape；Inner handle stent is placed in handle jacket, the rear end of inner handle stent have connected by axis pin and Symmetrical limit fastener, the lower end of limit fastener have and the buckle slot that circular ring shape limit stop ring engages on mandril, limiting card There is recess on the outside of button, inner handle stent 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 cavity rear portion of handle jacket has limiting stand, to limit the position of inner handle stent axially backward.

The width of buckle slot is more than the width of limit stop ring, to hold the axial movement of mandril certain size.

The medial surface of limit fastener is inclined surface, and the radial dilatation with the Forward with mandril front end departs from buckle slot Limit stop ring.

In the utility model, according to handle jacket PPSU macromolecule engineering plastics performances, with external force by handle jacket mandril In handle casing card slot, interference fit mounting means ensures that handle jacket mandril will not fall off.It is sterilized in handle jacket After finishing, inner handle stent can be inserted into from any angle, the limit fastener of inner handle stent, can under the action of rubber o-ring The circular ring shape limit stop ring of mandril in handle jacket is blocked, is ensured not easily to fall off；When disassembled, handle jacket is held, thumb is pressed The bar that bears down on one makes mandril move forward, and the front end of mandril squeezes limit fastener introversion inclined-plane so that buckle slot departs from limit stop ring.

The beneficial effects of the utility model are：The utility model can any angle installation or removal handle jacket, it is convenient Application；The encapsulation of handle jacket ensures that blood and body fluid will not enter its internal structure in surgical procedure；Handle jacket PPSU macromolecule engineering plastics performances ensure to lose in high-temperature sterilization.

Description of the drawings

The utility model is illustrated below according to attached drawing：

Attached drawing 1 is the structure diagram of handle jacket in the utility model；

Attached drawing 2 is the structural exploded view of inner handle stent in the utility model；

Attached drawing 3 is the mounting structure schematic diagram of the utility model；

In figure, 1 handle jacket, 1-1 limiting stands, 2 mandrils, 2-1 limit stop rings, 2-2 front ends, 3 inner handle stents, 4 limits Position buckle, 4-1 buckle slots, 4-2 recesses, 4-3 pin holes, 4-4 axis pins, 5 rubber o-rings.

Specific embodiment

The utility model is further described with reference to specific embodiment.

Embodiment 1

It is as illustrated in the accompanying drawings from 1 to 3 a kind of embodiment of shadowless lamp sterile handle in the utility model, which includes Handle jacket 1, mandril 2 and inner handle stent 3；Mandril is mounted on the tail end of handle jacket, mandril by way of interference fit With front end 2-2, the rear of front end is provided with the limit stop ring 2-1 of circular ring shape；Inner handle stent is placed in handle jacket, The rear end of inner handle stent has through axis pin connection and symmetrical limit fastener 4, and the lower end of limit fastener has and mandril The buckle slot 4-1 of upper circular ring shape limit stop ring engaging has recess 4-2 on the outside of limit fastener, and inner handle stent also has RUBBER O Type circle 5, rubber o-ring are stuck in the indent of limit fastener.

The limit stop ring of above-mentioned cirque structure can ensure that be engaged from any angle with limit fastener installation.

Handle jacket uses PPSU macromolecule engineering plastics.The inner cavity rear portion of handle jacket has limiting stand, in restriction The position of handle bracket axially backward.The width of buckle slot is more than the width of limit stop ring, to hold the axial direction of mandril certain size It is mobile.The medial surface of limit fastener is inclined surface, and the radial dilatation with the Forward with mandril front end makes buckle slot depart from /V Baffle ring.

In the embodiment, according to handle jacket PPSU macromolecule engineering plastics performances, handle jacket mandril is pacified with external force In handle casing card slot, interference fit mounting means ensures that handle jacket mandril will not fall off.It has been sterilized in handle jacket Cheng Hou can be inserted into inner handle stent from any angle, and the limit fastener of inner handle stent is under the action of rubber o-ring, cocker Firmly in handle jacket mandril circular ring shape limit stop ring, ensure it is not easily to fall off；When disassembled, handle jacket, thumb press are held Mandril makes mandril move forward, and the front end of mandril squeezes the interior lateral incline of two limit fasteners, and two limit fasteners are by mandril front end Extruding force and be turned out around axis pin so that limit fastener buckle slot depart from limit stop ring, it is ensured that smoothly remove hand Handle housing.

Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover among the right of the utility model.
