Abstract

The utility model relates to a visible operating apparatus for mini-incision percutaneous paracentesis lumbar intervertebral disc operation, comprising an operating tube, an optical interface, a chassis and a rear main body. The operating tube is provided with an endoscope cavity and a working cavity inside, and connected with the chassis at the rear. The chassis is connected with the optical interface and the rear main body. The interface of the rear main body is connected with the upper portion of the right side of the chassis and integrated with an ocular connection tube and an ocular cap by a joint. A visible passage is formed by the endoscope cavity of the rear main body of the operating tube and the endoscope cavity of the operating tube through a reflecting mirror, and the working cavity is electrode or fiber passage. The utility model solves the problem that the doctor operates according to experiences in an invisible state in the mini-incision percutaneous paracentesis lumbar intervertebral disc operation and can't perform melting and vapourization aiming at the tissues compressing the nerve thereby making a bad influence on the curative effect. The utility model makes the mini-incision percutaneous paracentesis lumbar intervertebral disc operation performed in a visible state, thereby enabling the melting and vapourizations on the tissues compressing the nerve, eliminating the potential existing risks, and improving the curative effect.

This utility model purpose is to be achieved by following technical proposals: comprise operation pipe, optical interface, base, back main body; The continuous base in the rear end of operation pipe, base connect optical interface, back main body; Back main body comprises that interface, eyepiece are taken over, eyepiece hood, and interface directly connects the right part upper end of base, is 35-40 ° of angle with base; Connect into an integral body by joint between interface and eyepiece adapter, the eyepiece hood, whole center cavity is the endoscope chamber; In the operation pipe endoscope chamber and working chamber are arranged; The endoscope chamber of back main body constitutes visual channel with the endoscope chamber of operation pipe by reflecting mirror, and working chamber is electrode or optical-fibre channel.

Endoscope's chamber diameter is the 2.6-2.8 millimeter.

The working chamber diameter is the 2.6-2.8 millimeter.

The utlity model has following advantage and good effect: have endoscope chamber and working chamber to constitute two passages in the operation pipe of this operator, a passage is placed endoscope, another passage is placed electrode special or special optic fibre, the main intravital endoscope in back can make operation carry out under visual state with the endoscope chamber of operation pipe by the visual channel that reflecting mirror constitutes, organizing of pressuring nerve melted targetedly or vaporized, eliminate the potential risk in the art, improved curative effect.

Four, description of drawings:

Fig. 1 is this utility model agent structure cutaway view.

Among the figure 1-operation pipe, 2-endoscope chamber, 3-working chamber, 4-optical interface, 5-base, 6-interface, 7-joint, adapters of 8-eyepiece, 9-reflecting mirror, 10-eyepiece hood, 11-quartz body, 12-eyepiece, 13-adjust circle, 14-fill in block up, 15-seal cover, 16-baffle ring, 17-support set, 18-support ring, 19-screening glass.

Five, the specific embodiment:

As shown in Figure 1, percutaneous puncture lumbar intervertebral disc Minimally Invasive Surgery visual operation device comprisesoperation pipe 1,optical interface 4,base 5, backmain body.Base 5 is inserted inoperation pipe 1 rear end, is divided intoendoscope chamber 2 and workingchamber 3 in theoperation pipe 1, and the optical channel thatendoscope chamber 2 is made up of quartz body is electrode special or special optic fibre passage in the working chamber 3.Base 5 is front and back two parts, and is plug-in between two parts, andoperation pipe 1 is played fixation.Optical interface 4 is contained inbase 5 left parts upper end, specifically be to open the hole that links to each other withoptical interface 4 inbase 5 left parts upper end, the hole can be screwed hole,optical interface 4 can be adopted withbase 5 be threaded, the hole communicates withendoscope chamber 2, and the light source that enters fromoptical interface 4 can directly enter endoscope chamber 2.Back main body comprisesinterface 6,eyepiece adapter 8,eyepiece hood 10, andinterface 6 directly connects the right part upper end ofbase 5, is 35 ° of oblique states of-40 ° of angle lappings withbase 5 and installs.Connect into an integral body byjoint 7 betweeninterface 6 andeyepiece adapter 8, theeyepiece hood 10, whole center cavity is the endoscope chamber.Endoscope's intracavity is put reflectingmirror 9,quartz body 11, eyepiece 12.Reflectingmirror 9 is contained in the seam of endoscope's chamber front end andbase 5, and the thing of looking in theendoscope chamber 2 is reflexed on theeyepiece 12, and byquartz body 11 transitive graph pictures,eyepiece 12 is adjusted the focal length observed image by adjustingcircle 13, byeyepiece hood 10 protection eyepieces.The related optics of endoscope's intracavity is commercially available finished product, and its imaging technique is a known technology.The right-hand member outside ofoperation pipe 1 andbase 5 and back body interior are equipped with support set 17,support ring 18 and inbase 5operation pipe 1 are played a supporting role, the effect that eyeglass in 16 pairs of endoscope chambeies ofbaffle ring 2 plays to stop, plug stifled 14 andseal cover 15 play dustproof, waterproof effect.
