Abstract

The utility model discloses a multifunctional hook special for abdominal cavity operations. The multifunctional hook special for the abdominal cavity operations is formed by a pull rod 1, a hook 6, a medical cold light source 7 and a draw hook 8. The multifunctional hook special for the abdominal cavity operations is characterized in that the pull rod 1 is a hollow straight rod, the hook 6 and the draw hook 8 are made of an organic glass material, and a light-emitting diode (LED) lamp 9 is embedded in a curved part. The multifunctional hook special for the abdominal cavity operations provides an objective indication on whether to enter an abdominal cavity in puncture, avoids backflow of air and puncture liquid, reduces damage to visceral organs caused by a steel puncture needle and enables a single person to perform operation conveniently. Compared with the prior art, the multifunctional hook special for the abdominal cavity operations has the advantages that the hook has light transmission performance, the mechanical intensity of the hook can meet the requirements for hook drawing, double claws are adopted in the special hook, the width of the hook is adjustable, the operating field can be exposed within a large range, and the hook is simple in structure, easy to process and difficult to damage.

Description

The special-purpose hook of multi-functional abdominal operation

One, technical field

This utility model relates to a kind of lighting for medical use drag hook, belongs to the special-purpose hook of multi-functional abdominal operation in technique with the apparatus field, medical surgery abdominal cavity.

Two, background technology

At present, hook, drag hook are a kind of surgery apparatuses commonly used, and its major function is to expose operating field through tractive, and the working place of operation is provided.Existing hook, drag hook are generally made with metal material; Its longitudinal section is similar to a question mark; The hook that has at present, drag hook can also provide illumination when realizing its major function, the structure of this type illuminating retractor has two kinds, and a kind of is that front end at hook, drag hook installs pea lamp additional; Another kind is an additional optical fibers on hook, drag hook.The Lighting hook of these two kinds of structures, the major defect of drag hook one are that the general drag hook of structure is complicated, have increased production cost and technology difficulty.The 2nd, all damage and illuminating effect are general easily for pea lamp and optical fibers.

Three, summary of the invention

The purpose of this utility model provides the special-purpose hook of a kind of multi-functional abdominal operation; The structure that overcomes existing metal material making employing pea lamp and fibre-optic Lighting hook, drag hook existence is more generally linked up with, drag hook is complicated; The deficiency that has increased production cost and technology difficulty and damaged easily; Simple through this utility model implementation structure, be easy to processing with not fragile.

The purpose of this utility model realizes through following technical scheme; The special-purpose hook of a kind of multi-functional abdominal operation is made up of pull bar (1), hook (6), Medical Cold Light Source (7) and drag hook (8), it is characterized in that described pull bar (1) is hollow direct rod shape; Its both sides are provided with grooved tracks (3); Hook (6) and drag hook (8) are fixed on the grooved tracks (3) through wing nut (4), can upper and lowerly move, and turn left and right; The handle place of its straight-bar is provided with an on and off switch (2), and the tail end of its straight-bar is fixedly connected the spring backguy (5) of Medical Cold Light Source (7); Wherein said hook (6) is the arc of curvature shape, and its front end head is ellipse, and the both sides, stage casing are curved down, and tail end is the Curved Flat arcuation, and its front end light-emitting area is an integral body to the tail end sensitive surface; Wherein said drag hook (8) is the arc of curvature shape, and the both sides, stage casing upwarp, and tail end is the Curved Flat arcuation, and its front end light-emitting area is an integral body to the tail end sensitive surface.

Described hook (6) and drag hook (8) adopt pmma material, and the front end light-emitting area is a surface polishing to the tail end sensitive surface, and the thickness of its crooked position is thicker than the evener position, and crooked position and evener interdigit seamlessly transit.

The embedded LED lamp of the crooked position of described hook (6) and drag hook (8) (9).

The beneficial effect of this utility model is:

1, has light transmission;

2, its mechanical strength can satisfy the needs of drag hook;

3, simple in structure, be easy to processing with not fragile,

4, this special use hook adopts two pawls, its width-adjustable joint, and operating field exposes on a large scale.

Four, description of drawings:

5, spring backguy 6, hook 7, Medical Cold Light Source 8, drag hook 9, LED lamp

Five, specific embodiment:

Come the technical scheme of this utility model is further specified below in conjunction with accompanying drawing 1.The special-purpose hook of described a kind of multi-functional abdominal operation is made up of pull bar 1, hook 6, Medical Cold Light Source 7 and drag hook 8, it is characterized in that described pull bar 1 is hollow direct rod shape; Its both sides are provided with grooved tracks 3; Hook 6 is fixed on the grooved tracks 3 through wing nut 4 with drag hook 8, can upper and lowerly move, and turns left and right; The handle place of its straight-bar is provided with an on and off switch 2, and the tail end of its straight-bar is fixedly connected the spring backguy 5 of Medical Cold Light Source 7; Wherein said hook 6 is the arc of curvature shape, and its front end head is ellipse, and the middle-end both sides are curved saddle down, and tail end is the Curved Flat arcuation, and its front end light-emitting area is an integral body to the tail end sensitive surface; Wherein said drag hook 8 is the arc of curvature shape, and its front end head is the snakehead type, and the middle-end both sides are and upwarp the ingot shape slightly, and tail end is the Curved Flat arcuation, and its front end light-emitting area is an integral body to the tail end sensitive surface.

Described hook 6 adopts pmma materials with drag hook 8, and the front end light-emitting area is a surface polishing to the tail end sensitive surface, and the thickness of its crooked position is thicker than the evener position, and crooked position and evener interdigit seamlessly transit.

The embedded LED lamp 9 of crooked position of described hook 6 and drag hook 8.

Clinically, hook 6 is fixed on the grooved tracks 3 through wing nut 4 with drag hook 8.Unclamp nut 4 adjustment hook 6 and drag hook 8 width and far and near distances, after adjustment finishes, tighten wing nut 4 will link up with 6 or drag hook 8 fix; Hook patient's tissues such as skin and flesh to hook 6 and drag hook 8, operative doctor is held pull bar 1 tight in one's hands it is suspended on the operating-table perimeter frame.Turn on the power switch 2, Medical Cold Light Source 7 and LED lamp 9 are thrown light on simultaneously, and pass through the elongation and the contraction of spring backguy 5; Intraperitoneal is thrown light on; It mainly is to utilize lucite to have the characteristics of light transmission, because lucite is a light substantia compacta, and air is a light thinning medium when light conducts therein; So total reflection can take place in the interface at lucite one air, can be effectively with the light of light source conduct to hook, the drag hook front end throws light on.

This utility model has also utilized lucite to have certain mechanical strength, can strengthen through particular structural, and its mechanical strength can satisfy the needs of hook, drag hook.
