Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The utility model provides a keep unchangeable electronic endoscope of camera imaging direction, including the portion of inserting, the portion of inserting includes the sleeve pipe and locates the camera module of sleeve pipe head end, sheathed tube front end stretches into to the human body chamber in saying. The tail end of the insertion part is connected with a handheld part, and an operator can operate the insertion part through the handheld part.
Referring to fig. 1 to 4, the cannula includes an inner tube 1 and an outer tube 2 sleeved outside the inner tube 1, and the inner tube 1 can be used as a water inlet/outlet channel and a surgical instrument channel. The camera module is arranged at the head end of the outer tube 2, and pictures in the cavity are shot through the camera module, so that medical workers can observe the pictures, the pathological changes can be found out, and the optimal treatment scheme can be worked out.
A gap is arranged between the inner pipe 1 and the outer pipe 2, and the inner pipe 1 and the outer pipe 2 are not fixedly connected, so that the inner pipe 1 can rotate in the outer pipe. The inner tube 1 comprises a bending end 11, a transition end 13 and a straight end 12, the bending end 11 is located at the head end of the inner tube 1, and the transition end 13 is connected with the bending end 11 and the straight end 12. The straight end 12 is straight, the transition end 13 is arc-shaped, the bending end 11 is straight, and an included angle is formed between the bending end 11 and the straight end 12. The inner pipe 1 is a hard pipe having a certain hardness, and may be made of stainless steel. The outer tube 2 is an elastic tube having elastic deformability. After the inner tube 1 is inserted into the outer tube 2, the bending end 11 and the transition end 13 push the head end of the outer tube 2 to have the same shape as the bending end 11 and the transition end 13. Therefore, when the inner tube 1 rotates, the bending end 11 rotates along the circumferential direction and touches the outer tube 2, so that the position of the outer tube 2 deviates, but because the inner tube 1 and the outer tube 2 are only in contact, not fixedly connected, and the outer tube 2 has certain elastic deformation capacity, the position of the arc-shaped part of the outer tube 2 only deflects and does not rotate, so that the camera module fixed on the outer tube 2 only can spatially translate, but the rotation cannot occur. Therefore, in the process of using the endoscope, the whole endoscope does not need to be rotated, the direction of the image and the direction of the display screen can be kept consistent forever, and medical staff can conveniently watch the image. Moreover, because only the inner tube 1 is rotated, the position of the outer tube 2 is basically kept unchanged, the inner wall of the cavity is not scraped, and the harm to the body of the patient is reduced to the minimum.
The bent end 11 and the straight end 12 of the inner tube 1 form an included angle, and the included angle ranges from 0 degree to 30 degrees. The movable range of the inner tube 1 is changed by changing the angle of the included angle, so that the movable range of the surgical instrument extending into the inner tube 1 is changed.
In the present embodiment, in order to provide the outer tube 2 with a certain elastic deformation capability, a spiral cut 21 is provided at the front end of the outer tube 2, so that the outer tube 2 has the capability of being elastically deformed like a spring tube, the spiral cut 21 completely covers the arc-shaped portion of the outer tube 2, and covers a portion of the flat end of the outer tube 2, and the outer tube 2 is also made of stainless steel. Because the outer tube 2 is cut with the spiral cut 21, the outer tube 2 has elasticity, and when the inner tube 1 rotates, the outer tube 2 has elastic deformation capacity and cannot rotate along with the inner tube 1.
Referring to fig. 5, in addition to the spiral cuts 21 cut on the outer tube 2, alternatively, staggered ring-shaped cuts may be cut at the front end of the outer tube 2 instead of the spiral cuts, so that the outer tube has elastic deformation capability. The staggered ring-shaped incisions comprise a plurality of ring-shaped incisions 22 which are arranged in the axial direction, each ring-shaped incision 22 has a seam 23, and the seams 23 are staggered in the radial direction.
The electronic endoscope further comprises a mainboard and a display screen, and the camera module and the display screen are respectively electrically connected with the mainboard. Image or video information transmission that the camera module was gathered gives the mainboard, the mainboard decodes the back and shows image or video information on the display screen to medical personnel observe.
The camera module comprises a CMOS imaging sensor and a plurality of LEDs, the CMOS imaging sensor is used for collecting images or video information in the cavity, and the LEDs are used for providing light sources for shooting of the CMOS imaging sensor. The size of the camera module is less than 3mm, and the camera module can easily enter the cavity through natural channels of most normal people for observation due to the greatly reduced volume,
the display screen with handheld portion connects as an organic wholely, handheld portion rotates and drives the display screen rotates. Particularly, the display screen can be arranged on the handheld portion, and medical staff can conveniently look over the display screen through eyes. The display screen may also be designed integrally with the hand-held portion.
To sum up, when medical personnel only rotate the inner tube, the inner tube is rotatory along the axial, the end of buckling of its front end rotates along the circumferencial direction, because the inner tube is the hard pipe, can contact with the outer tube when the end of buckling of inner tube is rotatory, and because there is the clearance between inner tube and the outer tube, and the outer tube is the elastic tube, consequently, the outer tube can not be along with the inner tube is rotatory, only can follow the inner tube and produce the deflection, consequently, fix the camera module on the outer tube and also can only produce the translation in space, can not appear rotatoryly, the direction that keeps image direction on the display screen and display screen is unanimous forever, make things convenient for medical. Moreover, because only the inner tube is rotated, the position of the outer tube is basically kept unchanged, and the harm to the body of a patient is reduced.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
