[0047] It can be explained that the diameter of the second working channel 5 can be 6.5 mm, 6 mm, 5 mm, 4 mm, 3.8 mm, 3 mm, 2 mm, 1 mm, 0.5 mm, etc. The second working channel 5 can be used to place an endoscope channel and a water sheath device.

[0048] In a preferred embodiment, the second working channel 5 forms a certain angle with the first working channel 4, the first working channel 4 passes through the main body 11 in a straight line, and the angle between the first working channel 4 and the second working channel 5 is 1° to 15°. Of course, it can also exceed 15° without affecting the effect of the technical solution. In the preferred embodiments, the following can be listed: 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, and further preferably: 10°.

[0051] It is worth mentioning that, as shown in Figure 6, the end portion 12 has a third plane, a fourth plane, and a third and fourth arc surfaces connecting the third plane and the fourth plane, which match the first plane 111, the second plane 112, and the first arc surface 113 and the second arc surface 114 connecting the first plane 111 and the second plane 112 of the main body portion 11.

[0052] See also Figure 3 , Figure 4 , Figure 6 As shown, in some embodiments, the end portion 12 includes a sleeve section and a tip section, the sleeve section is an overlapping section of the main body portion 11 and the end portion 12, and the overlapping section is as shown in FIG. Figure 3 , Figure 4 As shown in the step shape, the end portion 12 is clamped on the step shape of the main body 11, and the end portion 12 and the main body 11 form a detachable structure. The detachable structure can be achieved by using a certain amount of force or tools, and the detachable structure can achieve the effect of recovering the end portion 12.

[0053] In a preferred embodiment, the tip section 12 is of duckbill design. The duckbill design provides a gradually expanding working channel, which can minimize damage to surrounding tissues while ensuring smooth passage of surgical instruments. This design enables surgeons to operate with smaller incisions, reducing postoperative pain and recovery time. In addition, the duckbill design can provide a better field of view and operating space. Through the duckbill expansion, endoscopes and surgical tools can enter at the same time, and there is enough space for complex operations. This is very beneficial for treating complex spinal lesions and improves the accuracy and safety of the operation. The duckbill design also helps to stabilize the surgical channel and prevent instruments from sliding. This stability allows surgeons to control surgical instruments more accurately during operation and reduce the possibility of operating errors.

[0054] In some preferred embodiments, it can also be set to a pointed cone shape. Both the duckbill shape and the pointed cone shape can well open the minimally invasive affected area to facilitate subsequent surgical operations.

[0055] See also Figure 5 As shown, in some preferred embodiments, the side-entry dual-channel system is further provided with an inner core structure 3 adapted to the first working channel 4, and the inner core structure 3 is inserted into the first working channel 4. The inner core structure 3 is used to seal the first working channel 4, and when the endoscope system or the water sheath system passes through the second working channel 5, blood or human tissue is prevented from entering the first working channel 4. When the operation officially begins, the inner core structure 3 needs to be removed, and then the orthopedic medical device product is passed into the first working channel 4.

[0056] See also Figure 7 As shown, in some preferred embodiments, the positioning component 2 is fixedly connected to the main body 11, and the positioning component 2 and the main body 11 are an integrally formed structure. The positioning component 2 includes a first through hole 8 and a second through hole 9 that are respectively connected to the first working channel 3 and the second working channel 4. The positioning component 2 is fixedly connected to the main body 11 to ensure the stability and consistency of the side-entry dual-channel system. In addition, the positioning component 2 is integrally formed with the main body 11 to avoid assembly errors and looseness problems, thereby improving the accuracy and safety during the operation.

[0057] The positioning component 2 is provided with a first through hole 8 and a second through hole 9 which are connected to the first working channel 4 and the second working channel 5, which not only provides a path for the endoscope and surgical tools to enter, but also accurately locates the positions of the first working channel 3 and the second working channel 4, ensuring that the surgical instruments can accurately reach the target area.

[0058] The angle design of the two working channels of the side-entry dual-channel system of the utility model significantly improves the accuracy and efficiency of the operation. By making the second working channel and the first working channel form a certain angle, this design ensures that the imaging area of ​​the endoscope just covers the treatment area, realizes real-time observation of the treatment area, and effectively solves the problem of inconsistency between the imaging and treatment areas. This precise surgical field of view not only improves the accuracy of the operation, but also shortens the operation time and reduces the pain of the patient.

[0059] The injection molding process is used to put the end into the mold to form the main body, ensuring the tightness of the connection between the main body and the end, avoiding loose connection or gaps, thereby preventing blood or flesh from getting stuck during surgery, greatly improving the comfort during surgery. At the same time, it reduces the overall weight and cost of the system. In addition, the stable connection between the main body and the end ensures that it will not loosen or fall off during use, improving the overall reliability and safety.

[0060] The duckbill design provides a gradually expanding working channel, ensuring smooth passage of surgical instruments while minimizing damage to surrounding tissues. This design enables surgeons to operate with smaller incisions, reducing postoperative pain and recovery time. The duckbill design also provides a better field of view and operating space, allowing endoscopes and surgical tools to enter at the same time, providing enough space for complex operations, facilitating the treatment of complex spinal lesions, and improving the precision and safety of surgery. In addition, the duckbill design helps stabilize the surgical channel, prevents instruments from slipping, and enables surgeons to control surgical instruments more precisely, reducing the possibility of operating errors.
