Description
Technical field
This utility model relates to a kind of medical apparatus, relates in particular to a kind of trocar sheath of soft endoscope.
Background technology
In the prior art, endoscope is a pipe that is equipped with light and photographic head, and it can enter gastric through the oral cavity or enter in the body through other natural ducts.Utilize endoscope can see the pathological changes that X ray can not show, so it is very useful to the doctor.
Can change direction according to endoscope's shank clinically classifies: be divided into rigid endoscope and soft endoscope.The shank of described rigid endoscope is a hard material, can not change direction, its advantage is to stretch into the intravital shank of people can not change the position because of the extruding of organ in the human body, and the doctor can stretch out the direction of the outer shank control camera lens of human body by control, thereby reasonable visual angle is provided; The defective of rigid endoscope is that its flexibility ratio is not enough, and in some narrow and small cavity space or in some crooked ducts, rigid endoscope can't further stretch into focus, thereby reliable image can't be provided.The shank of described soft endoscope is that soft material is made, and bending by a relatively large margin can take place, and changes the direction of camera lens, and it can enter position comparatively narrow and crooked in the body cavity, directly arrives lesions position, and reliable lesion image is provided; But the rigidity of soft endoscope is not enough, the doctor controls the direction of soft endoscope external being difficult to, and under the extruding of organ, endoscope departs from the operating position easily, and the doctor is difficult to the direction of shank is adjusted and proofreaied and correct, thereby influences the carrying out of medical care precess.
Summary of the invention
The purpose of this utility model provides a kind of trocar sheath that is used for the soft endoscope of assist control endoscope shank direction.
For achieving the above object, the shank of endoscope partly is sheathed in the body of trocar sheath in this utility model, and the camera lens of endoscope stretches out from an end of body, wherein, the camera lens protruding end portion of described body is the bendable portion of plasticity, and the remainder of body is rigid sleeve pipe.Described bendable portion is mouldable snake-like hose.Adopt above structure, before trocar sheath inserts human body, the mouldable bendable portion of trocar sheath is adjusted to the degree of crook that needs, after inserting human body, the doctor holds in the body of trocar sheath, and the degree of depth that body control endoscope enters human body is adjusted in front and back, rotation body control endoscope shank direction.When the narrow or crooked position of endoscopy reaching, can fixed jacket pipe position, promote soft endoscope, make between endoscope and the trocar sheath relative slips takes place, soft endoscope further stretches into focus, for operation or diagnose the image document that the best is provided.
Be provided with airtight lobe in the tube chamber of the other end of body of the present utility model, between the outer wall of described endoscope shank and the inwall of trocar sheath body for hermetic seal, the tube wall of body be provided with fill air entry, described fill air entry be connected with tube chamber.Will to/deflated air pump be connected to fill on the air entry, can in the body cavity of human body, inflate by the body of trocar sheath on the one hand, make its expansion, body cavity walls can be separated with organ, thereby provides enough spaces for the observation or the operation technique of focus.On the other hand, also can discharge endoceliac gas, or the intraluminal tissue organ is adsorbed on the trocar sheath, suitably the position of moving tissue organ is operation technique or diagnostic observation slot milling.
One end of body of the present utility model is provided with air bag near the periphery of camera lens, and air bag is connected with the airbag aeration mouth that is arranged at the body other end by the connecting pipeline on the body.The described connecting pipeline that is connected with air bag can be arranged on the inwall or outer wall of body, perhaps is arranged in the tube wall of body.To be connected on the trachea to/deflated air pump, and as required air bag be inflated and aerofluxus, after airbag aeration expanded, the histoorgan around can propping up was for the observation or the operation technique of focus provides the space.
The outer wall axial direction of described body is provided with scale, and this design can make the doctor confirm that trocar sheath inserts the degree of depth of human body.The outer wall circumferencial direction of described body is provided with mark line, and the bending direction of body bendable portion can corresponding certain root mark line, inserts human body at trocar sheath, when the doctor can't perusal body bendable portion, confirms its bending direction by mark line.
The part that matches between the outer wall of the inwall of described body and endoscope's shank is coated with lubriation material.This design makes the inwall of body and the frictional resistance between endoscope's outer wall suitably reduce, and makes things convenient for doctor's operation.Described lubriation material can be a medical lubriation material of the prior art.
In sum, this utility model makes endoscope possess the advantage that the advantage of rigid endoscope handled easily shank direction and soft endoscope can deep enough focuses simultaneously, for doctor's diagnosis and operation technique provides reliable image document.

The specific embodiment
Shown in Fig. 1,2 or 3, shank 22 parts of endoscope 2 are sheathed in the body 1 of trocar sheath in this utility model, the camera lens 21 of endoscope 2 stretches out from an end 11 of body 1, wherein, the camera lens protruding end portion of described body 1 is the bendable portion 12 of plasticity, and the remainder of body 1 is rigid sleeve pipe.Described bendable portion 12 is mouldable snake-like hose.
Be provided with airtight lobe 14 in the tube chamber of the other end 13 of body 1 of the present utility model, be hermetic seal between the outer wall of described endoscope 2 shanks 22 and the inwall of trocar sheath body 1, the tube wall of body 1 be provided with fill air entry 15, described fill air entry 15 be connected with tube chamber.
One end 11 of body 1 of the present utility model is provided with air bag 3 near the periphery of camera lens 21, and air bag 3 is connected with the airbag aeration mouth 32 that is arranged at body 1 other end 13 by the connecting pipeline on the body 1 31.
Shown in Fig. 4,5 or 6, the described connecting pipeline 31 that is connected with air bag 3 can be arranged on the inwall or outer wall of body 1, perhaps is arranged in the tube wall of body 1.
The outer wall axial direction of described body 1 is provided with scale 16, and the outer wall circumferencial direction of described body 1 is provided with mark line 17.
The part that matches between the outer wall of the inwall of described body 1 and endoscope's 2 shanks 22 is coated with lubriation material.
Adopt above structure, before trocar sheath inserts human body, the mouldable bendable portion 12 of trocar sheath is adjusted to the degree of crook that needs, after inserting human body, the doctor holds in the body 1 of trocar sheath, the degree of depth that body 1 control endoscope enters human body is adjusted in front and back, rotation body 1 control endoscope 2 shanks, 22 directions.When endoscope 2 arrives narrow or crooked position, can fixed jacket pipe position, promote soft endoscope 2, make between endoscope 2 and the trocar sheath relative slip takes place, the camera lens 21 of soft endoscope 2 further stretches into focus, for performing the operation or diagnosing the image document that provides best.
Can in the body cavity of human body, charge into noble gas by tube chamber, make its expansion; Also can strut the histoorgan of obstruct the view to air bag 3 inflations, these designs can help the doctor to obtain best observation visual angle, and are the operation technique slot milling.
Simultaneously, can by fill air entry 15 discharge endoceliac gas, or the intraluminal tissue organ is adsorbed on the trocar sheath, suitably the position of moving tissue organ is operation technique or diagnostic observation slot milling.
The doctor can judge the insertion depth of endoscope 2 and trocar sheath body 1 and the direction of shank, thereby make things convenient for the doctor to adjust viewing angle by observing the scale 16 and the mark line 17 of body 1 outer wall.
