Abstract
The utility model relates to the technical field of medical instruments and aims at providing a device which can heat an endoscope eyepiece constantly and thermostatically in a surgical operation in which an endoscope is used. The utility model provides a warming sleeve for the endoscope eyepiece. The warming sleeve for the endoscope eyepiece is composed of a heating sleeve (1), an extension cord (2), a power supply switch device (3) and a fixed ring clip (4). The warming sleeve for the endoscope eyepiece is simple in structure, convenient to operate, time-saving, labor-saving, and capable of well reducing the condition that eyepiece fuzziness is caused by condensation of water vapor on the eyepiece by keeping the temperature of the endoscope eyepiece, and providing a reliable and clear view image for operation of the endoscope as much as possible.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of chamber mirror eyepiece steam jacket.
Background technology
The chamber mirror is a kind of as minimally invasive medical, is bringing into play more and more important effect in the operative treatment of the human body lacunas such as abdominal cavity, uterine cavity.In the endoscope-assistant surgery process, can't look at the visual area straight, need by mirror eyepiece direct observation visual area, chamber situation, or the eyepiece signal of video signal is transferred to display to observe the visual area situation.It is the prerequisite that endoscope-assistant surgery is carried out that chamber mirror eyepiece is clearly observed the visual area.
The reason that chamber mirror eyepiece is fuzzy has many, but the situation that each case all can run into is exactly owing to chamber mirror eyepiece temperature is low than temperature in the body cavity, and causing chamber mirror eyepiece one to enter in the body cavity will be at the eyepiece surface condensation globule, thereby affects the clear of chamber mirror eyepiece.Common solution clinically is with hot water chamber mirror eyepiece to be heated in advance.But this kind way can't be grasped the time that chamber mirror eyepiece need be heated accurately, in case and the attenuating of chamber mirror eyepiece temperature, water vapour can occur condensing again affects the visual field, needs again heat to it, thereby increases operator's operating time and difficulty.
There is no at present and be exclusively used in device lasting to chamber mirror eyepiece, heated at constant temperature.
The utility model content
The purpose of this utility model provide a kind of when using the chamber mirror to carry out operation technique to chamber mirror eyepiece continue, the device of heated at constant temperature.
This utility model provides a kind of chamber mirror eyepiece steam jacket, is comprised of heating jacket, extended line, power switch device and retainer ring folder; Wherein heating jacket is resilient cylinder-like structure, is evenly distributed with resistance wire in the heating jacket, and the set temperature inductive means; Extended line couples together heating jacket and power switch device, and extended line is provided with at least one retainer ring folder.
Described heating jacket can be stablized and surrounds chamber mirror eyepiece head end, equally distributed resistance wire in the heating jacket can make the temperature of heating jacket evenly rise, also have the temperature sense parts in it, when surpassing design temperature, thereby the supply of electric power that can cut off resistance wire makes the temperature of heating jacket stop to rise; When temperature is lower than design temperature, thereby the supply of electric power of resistance wire recovers to make the temperature of heating jacket to rise.
Described retainer ring folder can be more than two, and extended line is fixed on the mirror eyepiece of chamber, thereby avoids increase equipment on the impact of original chamber mirror operation.
The resistance wire that power switch device can be connected in the heating jacket with the power-supply device of routine provides electric power, and by handling the user mode of power switch device.
During use, heating jacket is enclosed within chamber mirror eyepiece head end, by the retainer ring folder extended line is fixed on the mirror eyepiece of chamber, connect power supply by power switch device, open switch energising heating jacket and namely start working the heating of chamber mirror eyepiece, reach target temperature (human body core temperature) and remain on this temperature levels.Get final product with complete this device is taken off from chamber mirror eyepiece.
This utility model is simple in structure, and is easy to operate, economizes time power, can be preferably by holding chamber mirror eyepiece temperature to reduce the eyepiece eyepiece ambiguity that steam produces of condensing, provide safe, field-of-view image clearly for the operation of chamber mirror as much as possible.
Description of drawings
Fig. 1 is overall structure sketch map of the present utility model;
Wherein: heating jacket 1, extended line 2, power switch device 3, retainer ring folder 4.
The specific embodiment
Now in conjunction with the embodiments and accompanying drawing, this utility model is further described, but enforcement of the present utility model is not limited in this.
Embodiment 1:
A kind of chamber mirror eyepiece steam jacket as shown in Figure 1, is comprised of heating jacket 1, extended line 2, power switch device 3 and retainer ring folder 4.Wherein heating jacket 1 is resilient cylinder-like structure, can stablize and surround chamber mirror eyepiece head end, equally distributed resistance wire in the heating jacket 1 can make the temperature of heating jacket 1 evenly rise, also have the temperature sense parts in it, when surpassing design temperature, thereby the supply of electric power that can cut off resistance wire makes the temperature of heating jacket 1 stop to rise; When temperature is lower than design temperature, thereby the supply of electric power of resistance wire recovers to make the temperature of heating jacket 1 to rise.Extended line 2 can couple together heating jacket 1 and power switch device 3, and two retainer ring folders 4 are arranged on the extended line 2, and extended line 2 is fixed on the mirror eyepiece of chamber.The resistance wire that power switch device 3 can be connected to the power-supply device of routine in the heating jacket 1 provides electric power, and by handling the user mode of power switch device 3.
This utility model can need be made different specifications and models by the specification of different cavity mirror eyepiece.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in above-described embodiment and the description just illustrates principle of the present utility model; this utility model also has various changes and modifications under the prerequisite that does not break away from this utility model spirit and scope, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
