CN2769692Y - Cold light source for direct-view minimally invasive gallbladder operation - Google Patents

Abstract

The utility model relates to a medical instrument, in particular to a direct-view minimally invasive gallbladder surgery retractor, which is a new surgery method and has high practical value. However, since the opening is small and needs to be enlarged, a draw hook is required. However, the use of this technique is limited because of the absence of a special retractor. Therefore, a direct-view minimally invasive gallbladder surgery retractor is developed. The method is characterized in that: the cold light source comprises an optical fiber 1, a metal hose 2 wrapped around the fiber, a tubular handle 3 behind the hose, and a connecting tube 4 screwed to the handle. When the light source works, the light source is connected through the wiring tube 4, and the front end of the hose 2 can emit light. The flexible tube 2 is inserted into the operation incision, so that the internal organs can be seen clearly, and the operation can be performed under direct vision.

Description

Direct-view Wicresoft operation on gallbladder cold light source

Technical field: the utility model relates to a kind of medicine equipment, promptly a kind of direct-view Wicresoft operation on gallbladder cold light source.

Background technology: direct-view Wicresoft operation on gallbladder is a kind of new operation method, mainly be by accurate in locating,, use special apparatus with the otch of 3-4mc, gall-bladder and region of interest are exposed under patient's the visual field, and then a kind of gallbladder removal operation of implementing.This method is littler than traditional cholecystectomy opening, and painful few, healing is fast, good effect.Though more greatly, appointed condition is required very low, be convenient to implement at basic hospital than the otch of Laparoscopic Cholecystectomy.Get a clear view, accurately and reliably, secondary damage is little, is easy to the patient accepts, thereby has very high practical value in addition., because opening is little, light is difficult to enter, and is difficult to see clearly situation in the abdomen, the carrying out of influence operation.

Summary of the invention: the purpose of this utility model provides a kind of lighting fixture that is suitable for looking at straight Wicresoft's operation on gallbladder.

Above-mentioned purpose is realized by following technical scheme, develop a kind of direct-view Wicresoft operation on gallbladder cold light source, be characterized in: this cold light source has an optical fiber, its coated outside metal hose, the optical fiber front end exposes, there is a pipe handle flexible pipe back, and the handle back is by the wire barrel that is threaded.

Adopt the direct-view Wicresoft operation on gallbladder cold light source of such scheme, can when operation, enter otch, illuminate the space in the otch, make the visual field more clear, bring convenience to operation.

Accompanying drawing is introduced: Fig. 1 is the front view of a kind of embodiment, and Fig. 2 is its left view.

Among the figure as seen: optical fiber 1, flexible pipe 2, handle 3, wire barrel 4.

Embodiment: as shown in the figure, this cold light source is made up of optical fiber 1, flexible pipe 2, handle 3, wire barrel 4 etc.During work, connect light source by wire barrel 4, the front end of flexible pipe 2 will send light.Flexible pipe 2 is inserted operative incision, can see the organ of the inside clearly, thereby under direct-view, undergo surgery.

Claims (1)

1. look at Wicresoft's operation on gallbladder cold light source straight for one kind, it is characterized in that: this cold light source has an optical fiber (1), its coated outside metal hose (2), optical fiber (1) front end exposes, there is a pipe handle (3) flexible pipe (2) back, and the handle back is by the wire barrel (4) that is threaded.
