[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents the selected embodiments of the present application.

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0040] In the present application, unless otherwise clearly specified and limited, a first feature being above or below a second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them.

[0042] In the prior art, the handle housing of an endoscope is usually formed by docking two sub-housings. Multiple buckle structures are arranged at intervals on the docking parts of the two housings for buckling. When the two housings are buckled, it is necessary to ensure that the positions of each buckle structure are aligned to complete the buckling, which increases the difficulty of the assembly and disassembly processes, and the buckle structure is easily damaged during the disassembly process. Therefore, it is difficult to repair the handle housing of the endoscope during the preparation process or during use.
[0043] In view of this, the first aspect of the present application provides a handle housing for an endoscope, such as Figure 1-Figure 14 As shown, including:
[0044] The first sub-shell 10 has a first alignment end 11 and a first covering end 12 along an extending direction of the first sub-shell 10 , and the first alignment end 11 has an alignment groove 13 .
[0045] The second sub-shell 20 has a second alignment end 21 and a second covering end 22 along the extension direction of the second sub-shell 20 , and the second alignment end 21 has an alignment protrusion 23;
[0046] The alignment protrusion 23 can be buckled into the alignment groove 13 along the extension direction of the first sub-shell 10 , so that the second sub-shell 20 can rotate relative to the first sub-shell 10 around the alignment groove 13 until the first covering end 12 and the second covering end 22 are covered.
[0047] In the above scheme, the handle housing of the endoscope is formed by docking the first sub-housing 10 and the second sub-housing 20. The proximal end of the first sub-housing 10 is set as the first alignment end 11, which is used for alignment when docking with the second sub-housing 20, and the distal end of the first sub-housing 10 is set as the first covering end 12, which is used for covering after aligning with the second sub-housing 20. The proximal end of the second sub-housing 20 is set as the second alignment end 21, which is used for alignment when docking with the first sub-housing 10, and the distal end of the second sub-housing 20 is set as the second covering end 22, which is used for covering after aligning with the first sub-housing 10.
[0048] In the extension direction of the first sub-shell 10, an alignment groove 13 is provided on the inner wall of the first alignment end 11. Similarly, in the extension direction of the second sub-shell 20, an alignment protrusion 23 is provided on the second alignment end 21 at a position corresponding to the alignment groove 13. In this way, when the first sub-shell 10 and the second sub-shell 20 are docked, the alignment protrusion 23 extends into the alignment groove 13, the first alignment end 11 and the second alignment end 21 are aligned, and the alignment protrusion 23 can rotate in the alignment groove 13, so as to realize the second sub-shell 20 covering and docking with respect to the first sub-shell 10 by rotating.
[0049] Therefore, the handle housing provided by the present application includes a first sub-housing 10 and a second sub-housing 20. By setting an alignment groove 13 at the first alignment end 11 of the first sub-housing 10 and setting an alignment protrusion 23 at the second alignment end 21 of the second sub-housing 20, the alignment protrusion 23 rotates with the alignment groove 13 to realize the end clamping of the first sub-housing 10 and the second sub-housing 20, and also provides a positioning function for the subsequent covering of the first sub-housing 10 and the second sub-housing 20. In the process of covering, the first sub-housing 10 and the second sub-housing 20 only need to align the alignment protrusion 23 with the alignment groove 13 for clamping, so that the alignment of other parts of the handle housing can be achieved, thereby reducing the difficulty of alignment of the handle housing during the covering process. At the same time, when the handle housing is disassembled for inspection, since only one end of the handle housing is clamped and aligned, it is easy to separate the first sub-housing 10 and the second sub-housing 20 after removing the bolts on the handle housing, reducing the difficulty of disassembly, and the alignment protrusion 23 can rotate in the alignment groove 13, reducing the damage to other buckle structures of the housing during the disassembly process.
[0050] According to some optional embodiments, the alignment protrusion 23 includes a connecting section 231 and an alignment section 232, one end of the connecting section 231 is connected to the second alignment end 21, and the other end is connected to the alignment section 232; in the extension direction of the second sub-shell 20, the alignment section 232 protrudes in a direction away from the second covering end 22.
[0051] In the above solution, the width direction is the direction intersecting with the extension direction of the second sub-housing 20. The connecting section 231 extends along the width direction of the second alignment end 21, one end of the connecting section 231 is integrally formed with the inner wall of the second alignment end 21, and the other end of the connecting section 231 is integrally formed with the alignment section 232, fixedly connected by gluing or the like, and after the second alignment section 232 is connected to the connecting section 231, the whole presents a hook shape. The alignment section 232 protrudes toward the alignment groove 13, and then the protruding part of the alignment section 232 can smoothly extend into the alignment groove 13, and the two are snap-fitted.
[0052] According to some optional embodiments, the angle between the abutting surface 2311 of the connecting segment 231 and the buckling surface 2321 of the aligning segment 232 is less than 90°.
[0053] In the above scheme, the surface where the connecting section 231 contacts the alignment groove 13 is the abutment surface 2311, and the surface where the alignment section 232 is buckled into the alignment groove 13 and is adjacent to the abutment surface 2311 is the buckling surface 2321. After the connecting section 231 is connected to the alignment section 232, the abutment surface 2311 is connected to the buckling surface 2321, and the buckling surface 2321 is inclined relative to the abutment surface 2311, that is, the angle between the abutment surface 2311 and the buckling surface 2321 is an acute angle, such as 3°, 6°, 15°, etc., so that the buckling between the alignment protrusion 23 and the alignment groove 13 is more firmly secured, thus preventing the alignment protrusion 23 from detaching from the alignment groove 13.
[0054] According to some optional embodiments, in the extension direction of the first sub-shell 10, the alignment groove 13 is recessed in the direction away from the first covering end 12; and a first guide surface 131 is provided on the alignment groove 13, and the alignment protrusion 23 is buckled into the alignment groove 13 along the first guide surface 131.
[0055] In the above solution, an alignment groove 13 is provided on the inner wall of the first alignment end 11, and the shape of the alignment groove 13 matches the shape of the alignment protrusion 23, so that the alignment protrusion 23 and the alignment groove 13 are firmly buckled. The alignment groove 13 is provided with a first guide surface 131 on the insertion path of the alignment protrusion 23, so that the alignment protrusion 23 can quickly enter the alignment groove 13, and at the same time, the alignment protrusion 23 can also smoothly slide out along the first guide surface 131.
[0056] According to some optional embodiments, a snap-fit rib 14 is provided on the first docking wall 15 of the first sub-shell 10 , a snap-fit groove 24 is provided at a corresponding position of the second sub-shell 20 , and the snap-fit rib 14 extends continuously from the first alignment end 11 to the first covering end 12 .
[0057] Exemplarily, when the first sub-shell 10 and the second sub-shell 20 are connected by snap-fitting, a snap-fitting rib 14 can be provided on the docking part of the first sub-shell 10, that is, the first docking wall 15, and the snap-fitting rib 14 is located between the first alignment end 11 and the first covering end 12, and the snap-fitting rib 14 extends continuously between the first alignment end 11 and the first covering end 12 without interruption. A snap-fitting groove 24 is provided on the docking part of the second sub-shell 20, that is, the second docking wall 25, and the first sub-shell 10 and the second sub-shell 20 are snap-fitted by the snap-fitting rib 14 and the snap-fitting groove 24. At the same time, in the present application, there is no snap-fitting structure when the first sub-shell 10 and the second sub-shell 20 are connected, so the snap-fitting rib 14 and the snap-fitting groove 24 can be made continuous, and after the first sub-shell 10 and the second sub-shell 20 are snapped together, the sealing will be better.
[0058] According to some optional embodiments, at least two alignment posts 26 are provided on the inner wall of the second sub-housing 20, and a post groove 16 is provided at a corresponding position of the first sub-housing 10, and a second guide surface 261 is provided on the side wall of the alignment post 26 adjacent to the second docking wall 25 of the second sub-housing 20. Exemplarily, the side wall of the alignment post 26 adjacent to the second docking wall 25 of the second sub-housing 20 can be a side of the alignment post 26 adjacent to the outer surface of the second sub-housing 20. The outer surface of the second sub-housing 20 is the surface located outside after the second sub-housing 20 and the first sub-housing 10 are covered.
[0059] In some optional embodiments, such as Figure 8As shown, two alignment posts 26 are disposed on the inner side walls of the second sub-housing 20 on both sides perpendicular to the extension direction of the second sub-housing 20. During the process of covering the first sub-housing 10 and the second sub-housing 20, the second guide surface 261 can be supported on the inner side wall of the first sub-housing 10, so that the first sub-housing 10 can slide along the second guide surface 261 and cover the second sub-housing 20.
[0060] In the above scheme, at least two alignment posts 26 are arranged at intervals on each of the left inner wall and the right inner wall of the second sub-housing 20. Optionally, one of the two alignment posts 26 can be arranged at the second alignment end 21 and one at the second cover end 22, thereby improving the strength of the positioning and matching of the handle housing. Optionally, the side wall of the alignment post 26 close to the second docking wall 25 is provided with a second guide surface, and the second guide surface 261 is an inclined surface, which is used for guiding when the first sub-housing 10 and the second sub-housing 20 are connected, making it easier to accurately align the two. During the docking process of the first sub-housing 10 and the second sub-housing 20, the first alignment end 11 is first docked with the second alignment end 21, and the part contains a traction wheel, so that the traction wheel can be positioned and installed first, thereby avoiding loosening or displacement of the traction wheel during the subsequent installation process.
[0061] Reference Fig. 9 In some optional embodiments, the alignment post 26 has a limiting surface 262 on one side adjacent to the outer surface of the second sub-shell 20. Exemplarily, the limiting surface 262 extends along the direction in which the first sub-shell 10 and the second sub-shell 20 overlap. When the first sub-shell 10 and the second sub-shell 20 overlap, at least a portion of the limiting surface 262 can be in contact with the inner side wall of the first sub-shell 10.
[0062] In the above embodiment, the limiting surface 262 is provided on the alignment post 26 to facilitate limiting the first sub-shell 10 and the second sub-shell 20 in a direction perpendicular to the extension direction of the second sub-shell 20 , thereby improving the reliability of the covering of the first sub-shell 10 and the second sub-shell 20 .
[0063] Reference Figure 8 , Fig. 9 and Fig.11 In some optional embodiments, at least part of the alignment post 26 protrudes from the covering surface 221 in the second sub-shell 20 that covers the first sub-shell 10. In some embodiments, the second guide surface 261 is disposed at one end of the alignment post 26 adjacent to the first sub-shell 10. In this way, it is beneficial to ensure that the second guide surface 261 first stops against the inner wall of the first sub-shell 10 during the covering process between the first sub-shell 10 and the second sub-shell 20, thereby providing guidance for the covering of the first sub-shell 10 and the second sub-shell 20.
[0064] In some optional embodiments, the limiting surface 262 is located at the portion of the alignment post 26 protruding from the covering surface 221. This is beneficial for preventing the first sub-housing 10 and the second sub-housing 20 from moving in a direction perpendicular to the extension direction of the second sub-housing 20.
[0065] In some optional embodiments, the alignment post 26 is located between the clamping groove 24 and the alignment protrusion 23. Exemplarily, the end of the clamping groove 24 adjacent to the alignment protrusion 23 is the first end. The alignment post 26 is located between the first end of the clamping groove 24 and the alignment protrusion 23, so that the alignment post 26 can be used to guide the first sub-shell 10 and the second sub-shell 20 to align before the connecting rib 14 is inserted into the clamping groove 24, thereby eliminating the need for an operator to adjust the position of the first sub-shell 10 and the second sub-shell 20 during the assembly process so that the connecting rib 14 is aligned with the clamping groove 24.
[0066] According to some optional embodiments, a first support member 27 is provided on the inner wall of the second sub-shell 20 adjacent to the second docking wall 25, and the first support member 27 extends along the extension direction of the second sub-shell 20; wherein, a plurality of first reinforcing ribs 28 are arranged at intervals between the first support member 27 and the second docking wall 25, and a third guide surface 281 is provided on the side wall of the first reinforcing rib 28 adjacent to the second docking wall 25.
[0067] In the above solution, optionally, the first support member 27 is a support plate, and a receiving cavity is formed between the first support member 27 and the inner wall near the second docking wall 25. In the extension direction of the second sub-shell 20, a plurality of first reinforcing ribs 28 are arranged at intervals to strengthen the strength of the second sub-shell 20. Optionally, a third guide surface 281 is arranged on the side wall of the first reinforcing rib 28 adjacent to the second docking wall 25, and the third guide surface 281 is an inclined surface, so that the inner wall of the first sub-shell 10 can be buckled with the second sub-shell 20 along the third guide surface 281.
[0068] Optionally, the second supporting member 27 extends continuously from the second alignment end 21 to the second covering end 22 .
[0069] According to some optional embodiments, a second support member 17 is provided on the inner wall of the first sub-shell 10 adjacent to the first docking wall 15, and the second support member 17 extends along the extension direction of the first sub-shell 10; wherein, a threading channel 18 is defined between the second support member 17 and the inner wall of the first sub-shell 10, and a plurality of second reinforcing ribs 19 are arranged at intervals in the threading channel 18, and in the width direction of the first sub-shell 10, the size of the second reinforcing ribs 19 is smaller than the size of the second support member 17.
[0070] In the above solution, optionally, the second support member 17 is a support plate, and a receiving cavity is formed between the second support member 17 and the inner wall close to the first docking wall 15, and the receiving cavity is a threading channel 18. A plurality of second reinforcing ribs 19 are arranged at intervals in the threading channel 18, and the height of the second reinforcing ribs 19 is lower than the height of the second support member 17, so as to avoid the cable from being unable to be accommodated in the threading channel 18. After the first sub-shell 10 and the second sub-shell 20 are buckled, the cable is placed in the threading channel 18, which avoids interference between the cable and the traction rope, and also avoids the cable from being clamped during the covering process.
[0071] In some optional embodiments, the handle housing is divided into a first sub-housing 10 and a second sub-housing 20 along the axis of the traction wheel, so that the traction wheel is also more convenient to install.
