Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an endoscope external instrument channel structure. Background Art

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has an image sensor, optical lens, light source, mechanical device, etc. It can enter the stomach through the mouth or enter the body through other natural channels. An endoscope can be used to see lesions that cannot be displayed by X-rays, so it is very useful for doctors. During surgical operations, an endoscope is often used in conjunction with a biopsy forceps or a basket to remove objects. On the one hand, an endoscope is needed, and on the other hand, a biopsy forceps or a basket is needed to operate together. This process is relatively cumbersome, and existing endoscopes do not have accompanying instrument channels, which is very troublesome during surgical operations and easily reduces the efficiency of surgical operations.

[0003] After searching, the existing Chinese patent publication number: CN208464027U is a medical endoscope, including an operating part and an insertion tube, a micro ultraviolet generator is installed on the top of the operating part, the right end of the operating part is connected to the insertion tube, and a central pipeline, an infusion pipeline, a liquid extraction pipeline and a first light guide are arranged inside the insertion tube, the infusion pipeline and the liquid extraction pipeline are respectively located at the top and bottom of the central pipeline, and light guide fibers are evenly arranged on the inner walls of the infusion pipeline and the liquid extraction pipeline.

[0004] The cited patent document also has the same problem. The insertion end of the endoscope does not have an instrument channel. During the surgical operation, since objects need to be removed, they often need to be removed with biopsy forceps or a basket. On the one hand, an endoscope is required, and on the other hand, biopsy forceps or a basket need to be used together. This process is relatively cumbersome and easily reduces the efficiency of the surgical operation. Utility Model Content

This structure includes a surgical instrument channel tube 2 arranged parallel to the peripheral outer wall of the endoscope insertion end component 1. The surgical instrument channel tube 2 can be combined with the endoscope insertion end component 1 to perform surgical operations, thereby replacing the use of biopsy forceps or net basket removal operations. The surgical instrument channel tube 2 is outside the endoscope insertion end component 1, so it can be disassembled and installed, which helps to install the surgical instrument channel tube 2 only when the operation needs to use it, without affecting the normal use of the endoscope insertion end component 1, thereby increasing the convenience of the operation and improving the efficiency of the surgical operation.

[0035] In this embodiment, the endoscope insertion end component 1 and the surgical instrument channel tube 2 are connected together by a channel fixing assembly 4, and the channel fixing assembly 4 includes a plurality of C-shaped fixing ring components 5 equidistantly sleeved on the outer wall of the endoscope insertion end component 1, and a plurality of fixing clamp components 7 equidistantly clamped on the outer wall of the surgical instrument channel tube 2.

[0036] Specifically, the fixing collar 5 is preferably in an annular structure, so that it can be sleeved on the peripheral side of the endoscope insertion end component 1, so that it can be assembled and used together with the fixing clamp 7. The fixing clamp 7 is preferably in a horizontal C-shaped structure, so that surgical instrument channel tubes 2 of different specifications and sizes can be clamped and installed. Since the fixing clamp 7 is made of elastic plastic material, it can be elastic, thereby clamping the surgical instrument channel tube 2 to prevent the surgical instrument channel tube 2 from falling off.

[0037] In this embodiment, the fixed collar member 5 and the fixed clamp member 7 are connected together in a detachable manner, and an upper convex platform 10 is integrally formed on the side of the fixed collar member 5 facing the fixed clamp member 7, and a lower convex platform 11 is integrally formed on the side of the fixed clamp member 7 facing the fixed collar member 5, a screw component 13 is integrally formed in the middle position of the bottom surface of the lower convex platform 11, and an internal threaded hole member 12 for the screw component 13 to be adapted and installed is provided in the middle position of the top surface of the upper convex platform 10.

[0038] Specifically, during installation, the fixing collar 5 is first equidistantly sleeved on the outer wall of the endoscope insertion end component 1, and the fixing clamp 7 is hand-held and screwed so that the screw component 13 and the internal threaded hole component 12 are threadedly connected together, so that the fixing clamp 7 is fixedly installed on the top surface of the fixing collar 5, and the upper convex platform 10 and the lower convex platform 11 are relatively abutted to increase the connection stability. At this time, the surgical instrument channel tube 2 is clamped in multiple fixing clamps 7, so that the fixing clamp 7 clamps the surgical instrument channel tube 2, so that the endoscope insertion end component 1 and the surgical instrument channel tube 2 are assembled and used, which is not only convenient for installation and disassembly, but also can meet the installation of surgical instrument channel tubes 2 and fixing clamps 7 of different specifications and sizes, thereby improving the use efficiency.

[0039] In the present embodiment, a linkage block component 6 capable of assisting the bending of the endoscope insertion end component 1 and the surgical instrument channel tube 2 is clamped between two adjacent fixed collar components 5 and between the endoscope insertion end component 1 and the surgical instrument channel tube 2. A first inner groove 15 for fitting and installing the surgical instrument channel tube 2 is transversely arranged in the middle position of the top surface of the linkage block component 6, and a second inner groove 16 for fitting and installing the endoscope insertion end component 1 is transversely arranged in the middle position of the bottom surface of the linkage block component 6.

[0040] Specifically, the first inner groove 15 is fitted and installed with the surgical instrument channel tube 2, and the second inner groove 16 is fitted and installed with the endoscope insertion end component 1, so that the linkage block component 6 is connected between the endoscope insertion end component 1 and the surgical instrument channel tube 2. When the endoscope insertion end component 1 needs to be bent, the linkage block component 6 can increase the friction between the endoscope insertion end component 1 and the surgical instrument channel tube 2, so that the endoscope insertion end component 1 and the surgical instrument channel tube 2 are tightly connected and will not fall off, thereby improving the connection stability.

[0041] In this embodiment, the circumferential outer walls between two adjacent fixed ring members 5 are symmetrically and integrally connected with auxiliary support connecting parts 8, the inner wall of each auxiliary support connecting part 8 abuts against the outer wall of the endoscope insertion end part 1, and the inner wall of each auxiliary support connecting part 8 is equidistantly and integrally formed with snap-fitting bosses 9, which are squeezed into the outer wall of the endoscope insertion end part 1, and the material of the auxiliary support connecting parts 8 is elastic plastic material.

[0042] Specifically, the auxiliary support connecting component 8 can connect multiple fixed ring components 5 without falling off or tilting, and the snap-fit ​​protrusion 9 squeezed into the outer wall of the endoscope insertion end component 1 can increase the friction of the fixed ring components 5 and improve the installation stability of the fixed ring components 5.

[0043] In this embodiment, the inner wall of each fixing clamp 7 is bonded with an anti-skid rubber pad 14, and the inner wall of the anti-skid rubber pad 14 abuts and wraps around the outer wall of the surgical instrument channel tube 2. Under the action of the anti-skid rubber pad 14, the friction with the surgical instrument channel tube 2 can be increased.

[0044] Working principle:

[0045] When installing the endoscope external instrument channel structure, firstly, the fixing collar 5 is equidistantly sleeved on the outer wall of the endoscope insertion end component 1, and the fixing clamp 7 is screwed by hand, so that the screw component 13 and the internal threaded hole component 12 are threadedly connected together, so that the fixing clamp 7 is fixedly installed on the top surface of the fixing collar 5, and the upper convex platform 10 and the lower convex platform 11 are relatively abutted to increase the connection stability. At this time, the surgical instrument channel pipe 2 is clamped in the multiple fixing clamps 7, so that the fixing clamp 7 clamps the surgical instrument channel pipe 2, so that The endoscope insertion end component 1 and the surgical instrument channel fitting 2 are assembled for use, the first inner groove 15 and the surgical instrument channel fitting 2 are fitted together, and the second inner groove 16 and the endoscope insertion end component 1 are fitted together, so that the linkage block component 6 is connected between the endoscope insertion end component 1 and the surgical instrument channel fitting 2. When the endoscope insertion end component 1 needs to be bent, the linkage block component 6 can increase the friction between the endoscope insertion end component 1 and the surgical instrument channel fitting 2 and will not fall off. The snap-on protrusion 9 is squeezed into the outer wall of the endoscope insertion end component 1.
