[0002] An endoscope is a commonly used medical device. In clinical use, an endoscope is inserted into the patient's body through natural openings or surgical incisions. It is typically equipped with a light source and a camera to transmit images to an external monitor for doctors to view and diagnose. In some applications, endoscopes need to be used with negative pressure suction devices to enable aspiration, allowing the removal of substances from the body, such as fluid accumulation or pathological samples.
[0003] The suction function of an endoscope relies on the connection between the negative pressure suction connector on its handle and the negative pressure suction tubing. In related technologies, the connection between the negative pressure connector and the handle housing is not secure, affecting the reliability of the negative pressure suction function.

[0036] An endoscope is a commonly used medical device. In clinical use, the endoscope is inserted into the patient's body through natural openings or surgical incisions. Then, using other surgical instruments and an image processor, surgical procedures can be performed inside the body from outside the body. In some applications, the endoscope needs to be used with a negative pressure suction device to enable suction capabilities, allowing the removal of substances from the body, such as fluid accumulation or pathological samples. The endoscope's suction function relies on the connection between the negative pressure suction connector on its handle and the negative pressure suction tubing. In current technology, the negative pressure suction connector is typically glued to the housing, making the glue bear the load of the negative pressure suction device tubing. During surgery, the tubing of the negative pressure suction device swings, constantly applying external force to the negative pressure suction connector, which accelerates the aging and failure of the glue, increasing the risk of the connector detaching from the housing and thus affecting the reliability of the negative pressure suction function.
[0037] Based on this, this application provides an endoscope handle structure that can solve the above-mentioned problems. The endoscope handle structure provided in one embodiment of this application will now be described in detail with reference to the accompanying drawings.
[0038] Referring to Figures 1 to 3, an embodiment of this application provides an endoscope handle structure 300 (hereinafter referred to as the handle structure), which includes a housing 310 and a first connector 320. The housing 310 is provided with a mounting cavity 311. The first connector 320 is used to communicate with a negative pressure suction device. A portion of the first connector 320 is accommodated in the mounting cavity 311. One of the first connector 320 and the cavity wall of the mounting cavity 311 is provided with a retaining bone 312, and the other is provided with a retaining groove 321. The first connector 320 is configured to be operably rotated so that the retaining bone 312 is screwed into and engaged with the retaining groove 321, and the groove wall of the retaining groove 321 prevents the retaining bone 312 from moving axially along the first connector 320. Understandably, the first connector 320 is provided with a first through hole extending along the axial direction (the axial direction is the up and down direction in the view of Figure 1, and it is also the length direction of the first connector 320). After the first connector 320 is connected to the housing 310, one end of the first through hole is used to connect to the pipeline of the negative pressure suction device, and the other end of the first through hole is used to connect to the mounting cavity 311. For example, in the embodiment shown in Figure 1, the upper end of the first connector 320 is used to connect to the negative pressure suction device, and the lower end of the first connector 320 is used to connect to the housing 310.
[0039] Compared to the prior art which uses glue for bonding, the handle structure 300 of the endoscope described above uses a corresponding retainer 312 and a retainer groove 321 between the first connector 320 and the housing 310. When the retainer 312 is engaged in the retainer groove 321, the groove wall of the retainer groove 321 prevents the retainer 312 from moving axially, thus reducing the possibility of the retainer 312 disengaging from the retainer groove 321. This reduces the problem of the swing load of the negative pressure suction device tubing being transmitted to the first connector 320 during surgery, which could lead to connection failure between the first connector 320 and the housing 310. It also improves the connection strength between the first connector 320 and the housing 310, enhances the reliability of the negative pressure suction function, and ensures clear vision in the surgical area.
[0040] In some embodiments, a retaining rib 312 may be provided on the outer wall of the first connector 320, and a retaining groove 321 may be provided on the cavity wall of the mounting cavity 311 of the housing 310; alternatively, a retaining groove 321 may be provided on the outer wall of the first connector 320, and a retaining rib 312 may be provided on the cavity wall of the mounting cavity 311 of the housing 310. Specifically, in the embodiments shown in Figures 1 to 3, the retaining groove 321 is provided on the outer wall of the first connector 320, and the retaining rib 312 is provided on the cavity wall of the mounting cavity 311. As shown in Figure 3, during assembly, the first connector 320 is first inserted into the mounting cavity 311 of the housing 310, and then the first connector 320 is rotated in the direction of the arrow shown in Figure 3, so that the retaining rib 312 on the housing 310 is engaged in the retaining groove 321 of the first connector 320. The groove wall of the retaining groove 321 prevents the first connector 320 from moving axially relative to the housing 310, reducing the possibility of the first connector 320 being dislodged from the housing 310 by external force load.
[0041] Furthermore, the gap between the first connector 320 and the housing 310 is filled with an adhesive such as glue. The glue bonding further enhances the connection between the first connector 320 and the housing 310, prevents the possibility of loosening, ensures the reliability of the first connector 320 set on the handle structure 300 housing 310, and improves the service life of the first connector 320.
[0042] Referring to Figures 3 to 5, in one embodiment, the first connector 320 is provided with an insertion groove 322 communicating with the slot 321. The insertion groove 322 extends axially along the first connector 320, and the slot 321 extends circumferentially along the first connector 320. That is, the insertion groove 322 and the slot 321 intersect and together form an L-shaped groove, so that when the first connector 320 is inserted axially into the mounting cavity 311 of the housing 310, the retaining bone 312 is correspondingly located in the insertion groove 322. In this position, the first connector 320 can move axially relative to the housing 310. As the first connector 320 rotates around its circumference, the retaining bone 312 can slide into the retaining groove 321 through the insertion slot 322, and then engage within the retaining groove 321. Without rotating the first connector 320 in the opposite direction, the retaining bone 312 will not exit from the retaining groove 321. Through the engaging cooperation between the retaining bone 312 and the retaining groove 321, the connection and fixation between the housing 310 and the first connector 320 are achieved. Simultaneously, as the usage time increases and the first connector 320 needs to be replaced, the insertion slot 322 allows the first connector 320 to be rotated out of the retaining groove 321 and into the insertion slot 322, thereby separating the first connector 320 from the housing 310 and facilitating replacement of the first connector 320.
[0043] Referring to Figures 3 to 5, in one embodiment, the first connector 320 has a first blocking portion 323 and a second blocking portion 324 protruding outwards radially (radial, i.e., perpendicular to the axial direction), which surround the slot 321. Thus, when the retaining clip 312 is engaged in the slot 321, the first blocking portion 323 and the second blocking portion 324 abut and limit the retaining clip 312, reducing the possibility of the retaining clip 312 disengaging from the slot 321. This, in turn, reduces the risk of relative movement between the first connector 320 and the housing 310, ensuring the reliability and stability of their connection.
[0044] Referring to Figures 3 to 5, in one embodiment, a portion of the first blocking portion 323 and the second blocking portion 324 extend circumferentially along the first connector 320, while another portion of the first blocking portion 323 extends axially along the first connector 320. That is, the first blocking portion 323 is an L-shaped blocking block, and the second blocking portion 324 can be an annular blocking block surrounding the outer wall of the first connector 320. For example, in this embodiment, the end of the first blocking portion 323 can abut against the second blocking portion 324. Of course, in other embodiments, there may be a gap between the end of the first blocking portion and the second blocking portion, the gap being smaller than the width of the locking bone (i.e., the axial dimension of the locking bone) to prevent the locking bone from dislodging from the slot.
[0045] Referring to Figures 3 to 5, in one embodiment, a limiting portion 314 is provided on the side of the retaining bone 312 opposite to the first connector 320 along the axial direction. When the retaining bone 312 is engaged with the retaining groove 321, the limiting portion 314 abuts against the side wall of the first blocking portion 323. This arrangement further increases the contact area between the first connector 320 and the housing 310, thereby reducing the possibility of relative displacement between the connector and the housing 310, improving the connection reliability and operational stability of the two, and reducing the possibility of loosening.
[0046] Referring to Figures 3 to 5, in one embodiment, the slots 321 include multiple slots 321, which are arranged circumferentially around the first connector 320. Correspondingly, multiple retaining bones 312 are provided, which are arranged circumferentially around the housing 310. For example, in this embodiment, there are two slots 321 and two retaining bones 312. The two slots 321 are evenly distributed on the first connector 320, and the two retaining bones 312 are evenly distributed on the housing 310. Through the cooperation of the multiple retaining bones 312 and slots 321, the contact area between the first connector 320 and the housing 310 is further increased, reducing the possibility of relative displacement between the connector and the housing 310, improving the connection reliability and usage stability, and reducing the possibility of loosening.
[0047] Referring to Figures 5 and 6, in one embodiment, one of the first connector 320 and the cavity wall of the mounting cavity 311 is provided with a foolproof rib 325, and the other is provided with a foolproof groove 313 for engaging with the foolproof rib 325. For example, in this embodiment, the outer wall of the first connector 320 is provided with a foolproof rib 325, and the cavity wall of the mounting cavity 311 of the housing 310 is provided with a foolproof groove 313. The foolproof rib 325 and the foolproof groove 313 limit the direction of the first connector 320 connected to the housing 310, preventing reverse installation and improving the assembly efficiency of the first connector 320 and the housing 310. In other embodiments, the positions of the foolproof rib and the foolproof groove can be interchanged, that is, the first connector is provided with a foolproof groove, and the cavity wall of the housing mounting cavity is provided with a foolproof rib.
[0048] Referring to Figures 3, 6 and 7, in one embodiment, the handle structure 300 further includes a second connector 330 for communicating with a negative pressure suction valve. A portion of the second connector 330 is accommodated in the mounting cavity 311. The second connector 330 is provided with a second through hole. When the first connector 320 is mated with the second connector 330, the second through hole and the first through hole of the first connector 320 are connected.
[0049] Specifically, one of the second connector 330 and the first connector 320 is provided with a backstop block 331, and the other is provided with a backstop groove 326 for engaging with the backstop block 331. For example, in this embodiment, the outer wall of the second connector 330 is provided with a backstop block 331, and the end of the first connector 320 facing the second connector 330 is provided with a backstop groove 326. Furthermore, multiple backstop blocks 331 and backstop grooves 326 are spaced apart, thus enabling quick docking of the first connector 320 and the second connector 330. In addition, when the first connector 320 is a straight tube and the second connector 330 is an L-shaped tube, by providing multiple backstop blocks 331 and backstop grooves 326, the interface orientation of the second connector 330 can be easily adjusted to adapt to actual usage requirements. In other embodiments, the positions of the backstop block and the backstop groove can be interchanged, that is, the first connector is provided with a backstop block, and the second connector is provided with a backstop groove.
[0050] In existing technologies, the negative pressure connector is integrated into the negative pressure suction valve, which causes the negative pressure suction device tubing to interfere with the operation of the negative pressure suction valve, thus causing inconvenience to the surgical procedure. This application connects the first connector 320 and the second connector 330 to the housing 310 of the handle structure 300. The first connector 320 is used to connect to the negative pressure suction device, and the second connector 330 is used to connect to the negative pressure suction valve. In other words, the first connector 320 and the second connector 330 spatially isolate the tubing of the negative pressure suction device from the negative pressure suction valve, thereby preventing the tubing from swinging during surgery and interfering with the surgeon's operation of the negative pressure suction valve, thus reducing the difficulty of the surgery and improving its convenience. Furthermore, the gap between the second connector 330 and the housing 310 can be filled with an adhesive such as glue to ensure a good connection between the second connector 330 and the housing 310.
[0051] In the assembly of the aforementioned endoscope handle structure 300, the first connector 320 is first inserted into the mounting cavity 311 of the housing 310, so that the retaining bone 312 inside the housing 310 is located in the insertion groove 322 of the first connector 320. During this process, the anti-misalignment rib 325 on the first connector 320 and the anti-misalignment groove 313 on the housing 310 cooperate to limit the direction and prevent the first connector 320 and the housing 310 from being installed backwards. After insertion, the first connector 320 is rotated, causing the bone clip 312 to slide from the insertion groove 322 into the clip groove 321. The clip groove 321's wall acts as a barrier, preventing the bone clip 312 from detaching and thus preventing the first connector 320 from separating from the housing 310. The second connector 330 is then inserted into the first connector 320, causing the anti-retraction block 331 on the second connector 330 to engage with the anti-retraction groove 326 on the first connector 320. Adhesive is then applied to the gap between the second connector 330 and the housing 310 to ensure a secure connection. Furthermore, the gap between the first connector 320 and the housing 310 can also be filled with adhesive to further enhance the connection, preventing loosening, improving the reliability of the negative pressure suction function, and ensuring a clear view of the surgical area.
[0052] Furthermore, one embodiment of this application also provides an endoscope (not shown) including the handle structure 300 of the endoscope as described above. Because this endoscope includes the handle structure of any of the above embodiments, the snap-fit engagement between the first connector and the housing reduces the problem of the swing load of the negative pressure suction device tubing being transmitted to the first connector during surgery, thus preventing connection failure between the first connector and the housing. This improves the connection strength between the first connector and the housing, enhances the reliability of the negative pressure suction function, and ensures clear visibility of the surgical area.
[0053] Understandably, the endoscope may also include an insertion section (not shown) and a display device (not shown), with a handle structure connected to the insertion section and also connected to the display device. During the use of the endoscope, the insertion section can be inserted into the patient's body, and images of the lesion area can be acquired through the camera module within the insertion section and displayed on the display device to facilitate diagnosis or treatment.
[0054] The endoscope in this embodiment can be a disposable endoscope, a reusable endoscope for a limited number of uses, or a reusable endoscope for an unlimited number of uses. The endoscope in this embodiment can be a bronchoscope, pyeloscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This embodiment does not specifically limit the type of endoscope.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
