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.

[0036] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. 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.

[0037] 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. Moreover, a first feature being above, above, and above a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below a second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] In addition, in the present application, "proximal" and "distal" refer to the far and near positions of the structure relative to human operation in the use environment, so as to facilitate the description of the positional relationship between components and facilitate understanding; for the same component, "proximal" and "distal" are the relative positional relationship of the component, not absolute; therefore, it should be understood from the perspective of realizing the principles of the present application, and should not deviate from the essence of the present application.

[0039] The inventors found in their research that in order for an endoscope to achieve the above-mentioned multiple functions, multiple functional devices need to be installed in the endoscope handle, which places high requirements on the endoscope handle housing. In the prior art, in order to reasonably arrange multiple functional devices on the handle housing, the handle housing is usually assembled from multiple sub-housings. After assembly, there will be multiple gaps between the sub-housings, and the gap between the functional devices installed at the joints of the multiple sub-housings and the sub-housings will increase, which reduces the sealing of the handle housing, reduces its strength, and makes it easy to be violently disassembled.

[0040] In view of this, the first aspect of the present application provides a handle housing for an endoscope, such as Figure 1-Figure 10 As shown, including:

[0041] The first sub-shell 10 and the second sub-shell 20 are butted against each other, and a butt joint 1020 is formed at the butt joint of the first sub-shell 10 and the second sub-shell 20. Exemplarily, in the present application, the handle shell adopts a structure in which the handle shell is split in half, that is, the handle shell is formed by butt jointing two sub-shells. In some optional embodiments, the first sub-shell 10 and the second sub-shell 20 can be butt jointed by gluing, clamping, etc.

[0042] At least one of the first sub-shell 10 and the second sub-shell 20 is provided with a mounting position 11, and the mounting position 11 is used to install functional devices. Exemplarily, functional devices such as a camera button, a suction valve, and an instrument mouth can be installed in the mounting position 11. Exemplarily, the first sub-shell 10 and the second sub-shell 20 are provided with at least one mounting position 11. Optionally, the mounting position 11 can be arranged in a variety of ways on the sub-shell, such as all the mounting positions 11 are arranged on the first sub-shell 10, all the mounting positions 11 are arranged on the second sub-shell 20, one mounting position 11 is arranged on the first sub-shell 10, and two are arranged on the second sub-shell 20, etc. In this application, there is no restriction on the number of mounting positions 11. In the extension direction of the butt joint 1020, the butt joint 1020 avoids the mounting position 11. Preferably, the mounting position 11 in the present application is a closed structure, such as the mounting position 11 is a mounting hole structure, and the mounting hole is a complete hole, not an open groove, nor a circular hole composed of two semicircular holes. The installation position 11 is completely disposed on one of the first sub-shell 10 and the second sub-shell 20 , and the joint 1020 avoids all the installation positions 11 and does not separate the installation positions 11 .

[0043] Therefore, the handle housing of the present application includes a first sub-housing 10 and a second sub-housing 20, and the butt joint 1020 of the first sub-housing 10 and the second sub-housing 20 avoids the installation position 11, so that the installation position 11 is completely set on one of the first sub-housing 10 and the second sub-housing 20. In this way, the handle housing is only formed by butting two sub-housings, and the butt joint 1020 is reduced; secondly, the installation position 11 is completely set on one sub-housing, which reduces the gap between the butt joint 1020 and the installation position 11, so that the strength of the handle housing is increased, the airtightness is increased, and it is not easy to be disassembled violently.

[0044] According to some optional embodiments, a connection joint 12 is provided at the distal end of one of the first sub-shell 10 and the second sub-shell 20. Exemplarily, the connection joint 12 is provided at the distal end of the first sub-shell 10, or the connection joint 12 is provided at the distal end of the second sub-shell 20, which is not limited here. The connection joint 12 is cylindrical, and the connection joint 12 is a complete closed structure, which is not spliced. The connection joint 12 is connected to the insertion sheath of the endoscope, and the distal end of the other extends to a position adjacent to the connection joint 12, so that the joint 1020 avoids the connection joint 12.

[0045] Exemplarily, the connection connector 12 is completely disposed at the distal end of one of the first sub-shell 10 and the second sub-shell 20, so that the connection connector 12 can be quickly docked with the insertion sheath of the endoscope and ensure the airtightness between the connection connector 12 and the insertion sheath of the endoscope.

[0046] According to some optional embodiments, an instrument port 13 is provided on the outer circumference of one of the first sub-shell 10 and the second sub-shell 20 , and the instrument port 13 is used to allow treatment instruments to enter the endoscope, and the joint 1020 avoids the instrument port 13 .

[0047] In the above embodiment, the instrument port 13 is arranged on the outer circumference of the first sub-shell 10, or the instrument port 13 is arranged on the outer circumference of the second sub-shell 20. The instrument port 13 is located on one side of the butt joint 1020, and the instrument port 13 is completely arranged on the outer circumference of one of the first sub-shell 10 and the second sub-shell 20, so that the instrument port 13 is not arranged on the butt joint 1020, and a new gap is formed between the instrument port 13 and the butt joint 1020, thereby ensuring the airtightness of the instrument port 13 and increasing the strength of the instrument port 13.

[0048] According to some optional embodiments, a wiring connector 23 is disposed at the proximal end of one of the first sub-shell 10 and the second sub-shell 20 , the butt joint 1020 avoids the wiring connector 23 , and the wiring connector 23 extends in a direction away from the butt joint 1020 .

[0049] In the above embodiment, the proximal end of the outer circumference of the first sub-shell 10 is provided with a wiring connector 23, or the proximal end of the outer circumference of the second sub-shell 20 is provided with a wiring connector 23. The wiring connector 23 is located on one side of the butt joint 1020, that is, the wiring connector 23 is completely provided on the proximal end of one of the first sub-shell 10 and the second sub-shell 20, which avoids the wiring connector 23 being provided on the butt joint 1020, and the wiring connector 23 and the butt joint 1020 form a new gap, thereby ensuring the airtightness of the wiring connector 23 and increasing the strength of the wiring connector 23.

[0050] According to some optional embodiments, a snap-in groove 22 is provided on the docking position of one of the first sub-shell 10 and the second sub-shell 20, and a snap-in rib 15 is correspondingly provided on the other. Exemplarily, when the first sub-shell 10 and the second sub-shell 20 are docked, the snap-in rib 15 is embedded in the snap-in groove 22. In some optional embodiments, when the first sub-shell 10 and the second sub-shell 20 are docked, glue is pre-placed in the snap-in groove 22, so that the docking of the first sub-shell 10 and the second sub-shell 20 is more stable and has better sealing. Among them, a limiting protrusion 21 is provided at the tail end of the outer groove top wall of the snap-in groove 22, and a limiting groove 14 cooperating with the limiting protrusion 21 is provided on the housing where the snap-in rib 15 is located.

[0051] In the above embodiment, it should be noted that the front end of the clamping groove 22 is the end adjacent to the distal end of the handle housing, and the tail end of the clamping groove 22 is the end adjacent to the proximal end of the handle housing. A limiting protrusion 21 is provided at the tail end of the outer groove top wall of the clamping groove 22, that is, the tail end of the outer groove of the clamping groove 22 will be raised in height. Similarly, a limiting groove 14 is provided at the corresponding position of the housing where the clamping rib 15 is located. Through the limiting cooperation of the limiting protrusion 21 and the limiting groove 14, the stopping effect of the first sub-housing 10 and the second sub-housing 20 at the tail end of the clamping groove 22 is increased, so that the first sub-housing 10 and the second sub-housing 20 are more firmly docked.

[0052] In some optional embodiments, a limiting protrusion may also be provided at the tail end of the inner groove top wall of the snap-fit ​​groove 22 to further enhance the limiting effect on the first sub-shell 10 and the second sub-shell 20 .

[0053] According to some optional embodiments, the limiting protrusion 21 extends in an arc shape along the circumferential direction of the outer groove of the clamping groove 22 .

[0054] In the above embodiment, the limiting protrusion 21 is an arc-shaped protrusion, and both ends of the limiting protrusion 21 extend along the circumferential arc of the outer groove top wall of the clamping groove 22, so that the first sub-shell 10 and the second sub-shell 20 can be more closely connected and have better sealing.

[0055] According to some optional embodiments, the extending height of the limiting protrusion 21 close to the outer groove tail end of the clamping groove 22 gradually increases.

[0056] In the above embodiment, the height of the limiting protrusion 21 near the rear end of the clamping groove 22 is greater than the height near the front end.

[0057] According to some optional embodiments, the thickness of the inner groove of the clamping groove 22 at the front end position of the turning point is greater than the thickness at other positions. That is, the radial dimension of the turning point of the inner groove of the clamping groove 22 at the front end position is increased, which greatly improves the strength of the handle housing, and also improves the anti-damage effect of the handle housing, and increases the life of the handle housing. Exemplarily, the thickness d1 of the inner groove of the clamping groove 22 at other places is greater than d2. <d2。

[0058] A second aspect of the present application provides an endoscope handle, comprising the above-mentioned handle housing.
