Abstract

The utility model provides a one-off limb fracture fixture, which comprises a cylindrical frame and splints and is characterized in that: The cylindrical frame is tapered with a large end and a slightly small end and composed of two semicircles. A joining line adopts moveable joint and the other joining line uses clasp joint. In addition, the cylindrical frame is circumferentially and vertically arranged with four outwards convex and equally distributed rectangular reinforcing rib lug bosses. A centerline of the lug boss is arranged with four equidistant thru screw holes. Slotted window holes are positioned amongst lug bosses. A slightly arch splint is arranged on a back side of the lug boss in the cylindrical frame. Blind holes with a quantity corresponding to the screw hole are positioned on the splint. Diameter of the blind hole is identical with that of the screw hole. Matched bolts are outwards screwed into the blind hole to joint. The fixture has the advantages of simple structure, lower production cost, reliable fixation, loosening and displacement prevention, operational convenience and using safety, enables fracture restoration details to be checked and corrected promptly, ensures cleanness and sanitation and particularly applies to hospitals.

Description

Disposable extremity fracture holder

(1) technical field:

This utility model belongs to medical equipment, specifically a kind of disposable extremity fracture holder.

(2) background technology:

At present, Chang Yong extremity fracture fixing means has two kinds basically clinically: the one, and train wheel bridge twines gauze to be fixed; The 2nd, do mould with Gypsum Fibrosum and fix.The former is little because of clamping plate plasticity, is easy to become flexible, and causes displacement, and clamping plate use repeatedly, and is very unhygienic; Latter's heaviness easily makes trouble limb blood circulation bad, in case generation displacement or para-position are bad, must cut Gypsum Fibrosum again, and program is loaded down with trivial details, wastes time, and causes patient's misery, and check is very inconvenient.

(3) utility model content:

The purpose of this utility model provides a kind of disposable extremity fracture holder, it have fixing reliable, safe in utilization, can not loose shift, can check and revise characteristics such as reduction of the fracture situation at any time.

In order to achieve the above object, the scheme that this utility model is taked is: this disposable extremity fracture holder comprises slightly curved clamping plate, it is characterized in that: one one big slightly, a slightly little slightly tapered tubular framework, involute by two semicircles, article one, involutory limit is for flexibly connecting, and another involutory limit is a snapping; Cylindrical shell circumferential periphery vertical direction be provided with 4 that outwards protrude, by the rectangle reinforcement boss that equal portions distribute, have 4 equidistant break-through screws on the centrage of boss, be provided with the fenestra of strip between each boss; The described curved splint of respective numbers is laid at the back side of boss platform in cylindrical shell, has on the clamping plate and the corresponding blind hole of screw number, and the aperture is consistent with the aperture of screw, is screwed in from the outside to put in the blind hole by the screw that matches to connect.

The utility model has the advantages that: simple in structure, cheap, fixing reliably, not become flexible, be not shifted, easy to operate, reset accurately, clarity, under X-ray, only need tight one tightly, unlay, the reduction of the fracture, fixing or correction can be made, and reduction of the fracture situation can be checked, revise at any time.

(4) description of drawings;

Fig. 1 is the structural representation of disposable extremity fracture holder.

(5) specific embodiment:

Below in conjunction with accompanying drawing this utility model is described in further detail: in Fig. 1, a is the viewgraph of cross-section of holder, and b is the expansion view of transversal line bottom semicircle, and c is the cutaway view of active connection, and d is the front view of clamping plate.As seen from the figure, it is a tubular framework 5 that is involuted by two semicircles (this framework is made of plastics or other plastic material), wherein one big slightly, one slightly little, it is slightly tapered that (upper end is narrower after seeing figure b expansion, the lower end broad can reflect), article one, involutory limit 6 is for flexibly connecting, take loose-leaf connected mode (seeing figure c) to embed indent by projection 8, long drift bolt 7 of reuse penetrates connection from the axis hole of upper end, make two lobes of framework can free folding, buckle is installed on another involutory limit 10, and (one has three, figure b is seen in the installation site), lockable when closing up can directly be pushed aside with hands.Cylindrical shell circumferential periphery vertical direction is provided with 4 rectangle reinforcement boss 1 (1 ' among the figure b only launches half for the boss of both sides) that outwards protrude, that distribute by equal portions, have 4 equidistant break-through screws 3 on the centrage of boss 1, be provided with strip fenestra 9 between each boss, the effect one of fenestra is ventilative, the 2nd, be convenient to observe.The back side of boss platform in cylindrical shell, lay the slightly curved clamping plate 11 (material of making clamping plate and cylindrical shell framework used material identical) of respective numbers, have on the clamping plate and the corresponding blind hole 4 of screw number, the aperture is consistent with the aperture of screw 3, screws in screw 3 from the outside by the screw 2 that matches and puts in directly that chucking connects in the blind hole 4 on the clamping plate 11.

The use of holder: in advance screw is screwed in the screw on the framework boss, makes blind hole suit on the clamping plate be clamped on the front end of screw.Face the time spent, push buckle aside the tubular framework is enclosed within patient's affected part, then with snap-lock, X-ray direct-view fracture reset or with manual reduction after, regulate each orientation screw to appropriate level, can play fixation to the reduction of the fracture.

Characteristics and needs according to age of patient, build, diseased region, this holder can be made the tandem product of different model, different specification size, designs the quantitative proportion of cylindrical shell, boss spacing, clamping plate, aperture size and the screw screw of different parameters on request.

Claims

1, a kind of disposable extremity fracture holder, comprise slightly curved clamping plate, it is characterized in that: one one big slightly, a slightly little slightly tapered tubular framework are involuted by two semicircles, article one, involutory limit is for flexibly connecting, and another involutory limit is a snapping; Cylindrical shell circumferential periphery vertical direction be provided with 4 that outwards protrude, by the rectangle reinforcement boss that equal portions distribute, have 4 equidistant break-through screws on the centrage of boss, be provided with the strip fenestra between each boss; The described curved splint of respective numbers is laid at the back side of boss platform in cylindrical shell, has on the clamping plate and the corresponding blind hole of screw number, and the aperture is consistent with the aperture of screw, is screwed in from the outside to put in the blind hole by the screw that matches to connect.
