Abstract
The utility model provides an LED illuminating hook for oral and maxillofacial deep tissues. The hook with LED illuminating light for the oral and maxillofacial deep tissues is made of medical stainless steel, is L-shaped on the whole, and comprises a hook handle and a hook body, wherein the hook handle and the hook body are independent mutually and are used after being assembled. The hook handle is in the shape of a cylinder and is hollow; and two C batteries of 1.5 V can be installed in the hook handle. A metal cover plate with screw threads is arranged at the bottom of the hook handle. The top end of the hook handle is a concave handle connector which is used for fixing and connecting with the hook body. A raised button and a metal cross rod are arranged at the middle part of the handle connector, the button is equal to a switch and is used for communicating a circuit, and the metal cross rod is used for fixing and limiting the movement of the hook body.
Description
Technical field
This utility model relates to a kind of Oral and Maxillofacial Surgery instrument.
Background technology
Drag hook is one of Oral and Maxillofacial Surgery apparatus commonly used, is an indispensable instrument that guarantees surgical field of view, acts on very important.Due to the specific (special) requirements of Oral and Maxillofacial Surgery to aesthetic property, operative incision is chosen in hidden oral cavity as far as possible in principle, and this just needs the cooperation of drag hook.existing universal drag hook can only play the effect that appears the visual area, but oromaxillo-facial region complex structure, add upper cut less, operative site is dark, existing drag hook usually can not appear deep tissue visual area, oral cavity fully, also can't direct view irradiation even reveal Astral lamp light, the firm internal fixation operation of jaw fracture of otch route in per os particularly, many positions such as cheekbone, upper jaw bone, angle of mandibles etc. all can't accurately be located and reset under direct-view, can only look lower operation blind according to patient's experience, this has increased certain risk and difficulty to operation technique, easy injured blood vessel, the important feature such as nerve, and because the visual field exposes insufficient operating time that extended.
The utility model content
The purpose of this utility model patent be to provide a kind of easy to use, can fully appear and provide can knowing of illumination to show the oral and maxillofacial surgery deep tissue surgery tractor with the LED houselights of oral and maxillofacial surgery deep tissue.
The technical solution of the utility model is as follows:
A kind of oral and maxillofacial surgery deep tissue drag hook with the LED houselights is made by medical stainless steel, and integral body is L-type, is comprised of drag hook handle and drag hook body, and two parts are independent mutually, and assembly unit is used.The drag hook handle is cylinder moulding inner hollow, and No. 2 1.5V batteries of two joints can be installed.The bottom is a threaded metal cover plate.The handle top is the handle connector of " recessed " font, is used for being connected and fixed the drag hook body.Have a raised button and a metal cross bar, button to be equivalent to switch in the middle of the handle connector and be used for UNICOM's circuit, cross bar fixed constraints drag hook body moves.
The drag hook body is L-type, is made by the medical stainless steel sheet, and the periphery circle is blunt smooth, is divided into drag hook connector, coupler body and optical fibre tube three parts.The drag hook connector is positioned at the lower end of drag hook body, is a cube column, and its front end has a U-shaped groove, and during use, it may be stuck in that on the cross bar of handle connector, the restriction drag hook moves.There are a spill button and handle button in drag hook connector below, to being applied to UNICOM's circuit.The rear end of drag hook connector has a screw to outward winding, and interiorly is hollow and one of LED illuminating lamp is installed.Coupler body is also stretched out forward in drag hook connector top, and its leading edge slightly is convexly curved, and is used for pulling open tissue and exposes surgical field of view, and the coupler body front end has an aperture, and optical fibre tube passes thus.There is an optical fibre tube front upper place of drag hook connector, and it is close to and is fixedly welded on coupler body, and the aperture top of being fixed in the drag hook body out of shape on the drag hook body is passed in its below that begins to be positioned at the drag hook body out of shape to drag hook body end.Optical fibre tube top is the light source joint, contains optical fibers, and surgical field of view is illuminated in tail end light directive gib head the place ahead.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of oral and maxillofacial surgery deep tissue drag hook with the LED houselights is made by medical stainless steel, and integral body is L-type, is comprised of drag hook handle and drag hook body, and two parts are independent mutually, and assembly unit is used.The drag hook handle is cylinder moulding inner hollow, and No. 2 1.5V batteries of two joints can be installed.The bottom is a threaded metal cover plate.The handle top is the handle connector of " recessed " font, is used for being connected and fixed the drag hook body.Have a raised button and a metal cross bar, button to be equivalent to switch in the middle of the handle connector and be used for UNICOM's circuit, cross bar fixed constraints drag hook body moves.The drag hook body is divided into drag hook connector, coupler body and optical fibre tube three parts.The drag hook connector is positioned at the lower end of drag hook body, is a cube column, and its front end has a U-shaped groove, and during use, it may be stuck in that on the cross bar of handle connector, the restriction drag hook moves.There are a spill button and handle button in drag hook connector below, to being applied to UNICOM's circuit.The rear end of drag hook connector has a screw to outward winding, and interiorly is hollow and one of LED illuminating lamp is installed.Coupler body is also stretched out forward in drag hook connector top, and its leading edge slightly is convexly curved, and is used for pulling open tissue and exposes surgical field of view, and the coupler body front end has an aperture, and optical fibre tube passes thus.There is an optical fibre tube front upper place of drag hook connector, and it is close to and is fixedly welded on coupler body, and the aperture top of being fixed in the drag hook body out of shape on the drag hook body is passed in its below that begins to be positioned at the drag hook body out of shape to drag hook body end.Optical fibre tube top is the light source joint, contains optical fibers, and surgical field of view is illuminated in tail end light directive gib head the place ahead.
