Description

Technical Field

[0001] The present invention relates to a sleeve assembly and an endoscope device, and particularly to a sleeve assembly and an endoscope device capable of reducing interference between instruments and facilitating adjustment of the viewing angle. Background Art

[0002] Generally, many surgical operations need to be assisted by an endoscope device. However, the existing endoscope devices have many aspects to be improved. For example, the internal space of the sleeve in the endoscope device is limited. Therefore, surgical tools and the endoscope inserted into the sleeve are prone to instrument interference. In addition, the field of view seen by the doctor through the endoscope inserted into the sleeve is also limited, and the appearance of the treatment site cannot be completely seen, easily resulting in imaging dead angles. The above situations may all cause risks during treatment.

[0003] Therefore, how to overcome the above defects through the improvement of structural design has become one of the important issues to be solved in this field. Summary of the Invention

[0004] The present invention provides a sleeve assembly and an endoscope device to solve the defects of the existing endoscope devices mentioned above.

[0005] To solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a sleeve assembly, which includes an outer sleeve and an inner sleeve. The outer sleeve has a first opening and a second opening that communicate with each other. The outer sleeve defines a central axis, and the central axis passes through the first opening and the second opening. The inner sleeve is detachably installed in the outer sleeve. The inner sleeve includes an annular member, and the annular member is disposed outside the outer sleeve and surrounds the outer sleeve. A part of the inner sleeve is disposed inside the outer sleeve and is in close contact with the inner wall of the outer sleeve. When the inner sleeve is operated, it can rotate about the central axis.

[0006] To solve the above technical problems, another technical solution adopted by the present invention is to provide an endoscope device, which includes a sleeve assembly and a lens assembly. The sleeve assembly includes an outer sleeve and an inner sleeve. The outer sleeve has a first opening and a second opening that communicate with each other. The outer sleeve defines a central axis, and the central axis passes through the first opening and the second opening. The inner sleeve is detachably installed in the outer sleeve. The inner sleeve includes an annular member, and the annular member is disposed outside the outer sleeve and surrounds the outer sleeve. A part of the inner sleeve is disposed inside the outer sleeve and is in close contact with the inner wall of the outer sleeve. When the inner sleeve is operated, it can rotate about the central axis. The lens assembly is installed in the inner sleeve.

[0007] One of the beneficial effects of the present invention is that in the sleeve assembly and the endoscope device provided by the present invention, a part of the inner sleeve is arranged on the side wall of the outer sleeve and surrounds the outer sleeve, and another part of the inner sleeve can be arranged inside the outer sleeve and closely attached to the inner wall of the outer sleeve. Thus, when the lens assembly is installed in the inner sleeve, it will closely lean against the inner wall of the outer sleeve, avoiding occupying too much internal space of the outer sleeve and interfering with other surgical instruments. In addition, through the design of the annular part of the inner sleeve surrounding the outer sleeve, the endoscope can freely move along the inner wall of the outer sleeve, enabling the user (i.e., the doctor) to see different areas of the hand part, so as to solve the problem of image dead angles in existing endoscopes.

[0018] Embodiment

[0019] Refer to Figure 1 and Figure 2 as shown, Figure 1 which is a three-dimensional schematic view of the sleeve assembly of the present invention, Figure 2 and which is a side view schematic view of the sleeve assembly of the present invention. The present invention provides a sleeve assembly M, which includes an outer sleeve 1 and an inner sleeve 2. The inner sleeve 2 is detachably installed in the outer sleeve 1.

[0020] The outer sleeve 1 is a cylindrical hollow sleeve having a first opening 11 and a second opening 12 that communicate with each other. Along the direction from the first opening 11 of the outer sleeve 1 to the second opening 12, the outer sleeve 1 can define a central axis C passing through the first opening 11 and the second opening 12. Further, the outer sleeve 1 further includes a connecting rod 13. The present invention does not limit the shape of the connecting rod 13. The connecting rod 13 has a first end 131 and a second end 132. The first end 131 is connected to the outer wall 101 of the outer sleeve 1, and the second end 132 has an end face E, and the central axis C is perpendicular to the end face E.

[0021] As Figure 1 shown, the second end 132 of the outer sleeve 1 has a notch, so the outer sleeve 1 can be fixed to an external device in various ways, such as by snap connection, mortise and tenon connection, or by stud connection, through the notch on the connecting rod 13 to ensure that the installation direction of the outer sleeve 1 is perpendicular to the end face E.

[0022] Refer to Figures 3 to 5 as shown, Figure 3 which is a first three-dimensional schematic view of the inner sleeve of the sleeve assembly of the present invention, Figure 4The second three-dimensional schematic diagram of the inner sleeve of the sleeve assembly of the present invention, Figure 5 is the third three-dimensional schematic diagram of the inner sleeve of the sleeve assembly of the present invention. The inner sleeve 2 includes an annular member 21, a body 22, a first end 23 and a second end 24. The first end 23 and the second end 24 are respectively connected to both ends of the body 22. A first card slot 231 is formed on the top end face 230 of the first end 23, and a connecting portion 233 is provided on the opposite side of the top end face 230 of the first end 23. Further, the first end 23 protrudes from one side of the body 22, so that the first end 23, the connecting portion 233 and the body 22 can jointly form a second card slot 232.

[0023] Further, the annular member 21 further has an opening 211, and the connecting portion 233 of the first end 23 is connected to the annular member 21 on the opposite side of the opening 211. As Figure 1 shown in Figure 3 , due to the opening 211 structure of the annular member 21, the annular member 21 is basically an annular cantilever. When the outer sleeve 1 and the inner sleeve 2 are assembled with each other, the annular member 21 of the inner sleeve 2 is clamped on the outside of the outer sleeve 1 and surrounds the outer wall 101 of the outer sleeve 1. In addition, the second card slot 232 is clamped on the edge 110 of the first opening 11 of the outer sleeve 1, so that the inner sleeve 2 is closely attached to the inner wall 102 of the outer sleeve 1. Through the structural design of the annular member 21 and the second card slot 232, the inner sleeve 2 can be stably installed on the outer sleeve 1, and can also be closely attached to the inner wall 102 of the outer sleeve 1 and move freely along the inner wall 102, so that the inner sleeve 2 can rotate along the central axis C of the outer sleeve 1.

[0024] Continuing to refer to Figures 3 to 5 , the inner sleeve 2 has a first channel opening 251 and a second channel opening 252 that communicate with each other. The first channel opening 251 is arranged in the first card slot 231, and the second channel opening 252 is arranged at the second end 24. As Figure 4 shown in Figure 1 , the contour of the second end 24 is tapered along the body 22 in the direction of the second channel opening 252. The inner sleeve 2 also has a third channel opening 253 and a fourth channel opening 254 that communicate with each other. The third channel opening 253 is arranged on the top end face 230 of the first end 23. Specifically, a convex column B (see Figure 1 ) can be formed on the top end face 230 of the first end 23, and the third channel opening 253 is the through opening on the convex column B. The fourth channel opening 254 is arranged on the side of the body 22 and close to the second end 24. In addition, as Figure 4 shown in

[0025] Referring to Figure 6 and Figure 7 shown in Figure 6Schematic diagram of the assembly of the endoscope and the inner sleeve of the present invention Figure 7 Stereoscopic schematic diagram of the endoscope device of the present invention. The present invention provides an endoscope device D, which may include the above-mentioned sleeve assembly M and a lens assembly P. The lens assembly P may be installed in the inner sleeve 2. Specifically, the lens assembly P is an endoscope, which can be inserted into the first channel opening 251 along a direction S1 and exposed from the second channel opening 252. In addition, the endoscope device D can also be externally connected to a flushing pipeline (not shown in the figure), and the flushing pipeline can be inserted into the third channel opening 253 (shown in Figure 3 and water is transported out from the fourth channel opening 254 (shown in Figure 6 ).

[0026] When the user (i.e., the doctor) operates the endoscope device D of the present invention to perform minimally invasive surgery, the sleeve assembly M extends from the surface surgical incision of the patient into the patient's body. Then, the lens assembly P extends into the inner sleeve 2, and the surgical tool can extend into the outer sleeve 1 to reach the part of the patient where surgery is required. The lens assembly P can be electrically connected to an external microscope device or display screen (not shown in the figure). Therefore, the doctor can see the actual situation of the surgical site recorded by the lens assembly P through the microscope while operating the surgical tool to perform minimally invasive surgery.

[0027] As Figure 3 and Figure 6 shown, the head P1 of the lens assembly P can be clamped in the first card slot 231. Thus, the lens assembly P can be fixed to the inner sleeve 2 and will not shake when the inner sleeve 2 moves along the inner wall 102 of the outer sleeve 1, which affects the user's viewing of the picture. Since a part of the inner sleeve 2 abuts against the inner wall 102 of the outer sleeve 1 and rotates along the central axis C of the outer sleeve 1, the lens assembly P does not occupy too much space inside the outer sleeve 1. Therefore, when the doctor operates the surgical tool to perform surgery, there is enough space inside the outer sleeve 1 for the doctor to operate the surgical tool, and the surgical tool will not interfere with the lens assembly P. In addition, since the inner sleeve 2 can move along the inner wall 102 of the outer sleeve 1, the user can conveniently change the position of the lens assembly P to adjust the viewing angle and see different areas of the hand part, avoiding blind spots in the field of view.

[0028] In addition, during the surgery, sometimes a small part of the body tissue needs to be removed. For example, in minimally invasive spinal decompression surgery, a surgical drill is used to drill holes or grind the bone spurs of the intervertebral disc, so a small amount of bone debris will be generated. These surgical products may remain at the surgical site and block the lens of the lens assembly P. At this time, water can be transported through the flushing pipeline to clean the surgical site.

[0029] Continue to refer to Figure 6 and Figure 7, the second end portion 24 further has a notch 241 which communicates with the second channel opening 252 and is adjacent to the fourth channel opening 254. The contour of the notch 241 gradually widens from narrow to wide along the body 22 in the direction of the second channel opening 252. Through the structural design of the notch 241, more parts of the lens assembly P extending to one end of the second end portion 24 can be exposed, and the water flowing out of the fourth channel opening 254 of the flushing tube can flow down along the notch 241 to further clean the lens of the lens assembly P.

[0030] Furthermore, in one embodiment of the present invention, the inner sleeve 2 and the outer sleeve 1 can be transparent or semi-transparent, so that light can penetrate through the inner sleeve 2 and the outer sleeve 1 to illuminate the surgical site. In other words, the brightness of the image seen by the user from the lens assembly P can be greatly improved.

[0031] In addition, as Figure 7 shown, the endoscope device D of the present invention may further include a marking module 3 and at least one marking component 4. The marking module 3 can be arranged on the connecting rod 13 of the outer sleeve 1, and at least one marking component 4 is arranged on the inner sleeve 2. The marking module 3 can be composed of a plurality of infrared reflective balls; similarly, at least one marking component 4 can be an infrared reflective ball. The marking module 3 and at least one marking component 4 can form a spatial coordinate system by using infrared positioning technology. Therefore, when the inner sleeve 2 and the lens assembly P arranged thereon rotate relative to the outer sleeve 1, the rotation angle of the inner sleeve 2 and the lens assembly P relative to the outer sleeve 1 can be calculated through the configuration of the marking module 3 and at least one marking component 4, so as to correct the orientation of the endoscope image displayed on the screen.

[0032] Advantageous effects of the embodiment

[0033] The sleeve assembly M and the endoscope device D provided by the present invention can be arranged on the side wall of the outer sleeve 1 and surround the outer sleeve 1 through the design of the annular part 21 and the second card slot 232 of the inner sleeve 2, so that a part of the inner sleeve 2 can be arranged inside the outer sleeve 1 and closely attached to the inner wall 102 of the outer sleeve 1. Thus, when the lens assembly P (i.e., the endoscope) is installed on the inner sleeve 2, it will closely adhere to the inner wall 102 of the outer sleeve 1, avoiding occupying too much internal space of the outer sleeve 1 and interfering with other surgical instruments. In addition, through the design that the annular part 21 of the inner sleeve 2 clamps and surrounds the outer sleeve 1 and the second card slot 232 is clamped on the edge 110 of the first opening 11, the lens assembly P can freely move along the inner wall 102 of the outer sleeve 1, enabling the user (i.e., the doctor) to conveniently change the position of the lens assembly P to adjust the viewing angle and see different areas of the hand part, so as to solve the problem of image dead angles in existing endoscope devices.

[0034] In addition, the endoscope device D can also be externally connected to a flushing pipeline (not shown in the figure). The flushing pipeline can be inserted into the third channel port 253 and deliver water to flow out from the fourth channel port 254 to clean the generated substances remaining at the surgical site. Further, through the design of the incision 241 at the second end portion 24 of the inner sleeve 2, the water flowing out from the fourth channel port 254 along the flushing tube can flow down along the incision 241 to further clean the lens of the lens assembly P.
