It is usually equipped with a light source and a camera, which can transmit images to an external display for doctors to view and diagnose. In some application scenarios, the endoscope needs to be equipped with a negative pressure suction device to enable the endoscope to have suction capabilities to suck out the objects to be sucked in the human body, such as effusions, pathological samples, etc.

[0003] The suction function of the endoscope depends on the connection between the negative pressure suction connector on the handle and the negative pressure suction pipeline. In the related art, the connection between the negative pressure connector and the handle housing is not firm, which affects the reliability of the negative pressure suction function.

[0036] Endoscope is a commonly used medical device. In clinical use, the endoscope enters the patient's body through the natural orifices of the human body or the incision formed by surgery, and then other surgical instruments and image processors can be used to perform in vivo surgical operations in vitro. In some application scenarios, the endoscope needs to be equipped with a negative pressure suction device to enable the endoscope to have suction capabilities to suck out the objects to be sucked in the human body, such as effusions, pathological samples, etc. The suction function of the endoscope depends on the connection between the negative pressure suction connector on its handle and the negative pressure suction pipeline. In the prior art, the negative pressure suction connector and the shell are usually fixed by glue, so that the glue bears the load of the negative pressure suction device pipeline. During the operation, the negative pressure suction device pipeline swings, and the negative pressure suction connector is continuously applied with external force, which will accelerate the aging and failure of the glue, and increase the risk of the negative pressure suction connector falling off from the shell, thereby affecting the reliability of the negative pressure suction function.

[0037] Based on this, the present application provides a handle structure of an endoscope, which can solve the above problems. The handle structure of an endoscope provided by an embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0038] Referring to Figures 1 to 3, a handle structure 300 (referred to as the handle structure) of an endoscope provided in an embodiment of the present application includes a shell 310 and a first joint 320, wherein the shell 310 is provided with a mounting cavity 311; the first joint 320 is used to communicate with a negative pressure suction device, a portion of the first joint 320 is accommodated in the mounting cavity 311, and one of the first joint 320 and the cavity wall of the mounting cavity 311 is provided with a clamping bone 312, and the other is provided with a clamping groove 321; the first joint 320 is configured to be operably rotated so that the clamping bone 312 is screwed into and clamped in the clamping groove 321, and the groove wall of the clamping groove 321 blocks the clamping bone 312 from moving axially along the first joint 320. It can be understood that the first connector 320 is provided with a first through hole extending in the axial direction (the axial direction is the up and down direction in the view of Figure 1, and is also the length direction of the first connector 320). After the first connector 320 is docked with the shell 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 installation 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 shell 310.

[0039] Compared with the prior art which adopts the glue bonding method, the handle structure 300 of the above-mentioned endoscope adopts the method of setting corresponding clamping bones 312 and slots 321 between the first joint 320 and the shell 310 in the present application. When the clamping bones 312 are clamped in the slots 321, the slot walls of the slots 321 prevent the clamping bones 312 from moving axially, thereby reducing the possibility of the clamping bones 312 being separated from the slots 321, thereby reducing the problem of the swing load of the pipeline of the negative pressure suction device being transmitted to the first joint 320 during the operation, resulting in the connection failure between the first joint 320 and the shell 310, thereby improving the connection firmness between the first joint 320 and the shell 310, improving the reliability of the use of the negative pressure suction function, and ensuring the clarity of the field of view in the surgical area.

[0040] In some embodiments, the first joint 320 may be provided with a clamping bone 312 on the outer wall, and the housing 310 may be provided with a clamping groove 321 on the cavity wall of the housing 310 installation cavity 311; or the first joint 320 may be provided with a clamping groove 321 on the outer wall, and the housing 310 may be provided with a clamping bone 312 on the cavity wall of the housing 310 installation cavity 311. Specifically, in the embodiments shown in FIGS. 1 to 3, the clamping groove 321 is provided on the outer wall of the first joint 320, and the clamping bone 312 is provided on the cavity wall of the housing 310 installation cavity 311. As shown in FIG. 3, during assembly, the first joint 320 is first inserted into the installation cavity 311 of the housing 310, and then the first joint 320 is rotated in the direction of the arrow shown in FIG. 3, so that the clamping bone 312 on the housing 310 is clamped into the clamping groove 321 of the first joint 320, and the first joint 320 is blocked from moving axially relative to the housing 310 by the groove wall of the clamping groove 321, thereby reducing the possibility of the first joint 320 being separated from the housing 310 by external force load.

[0041] Furthermore, the gap between the first joint 320 and the shell 310 is filled with an adhesive such as glue, and the connection effect between the first joint 320 and the shell 310 is further improved through glue bonding to prevent the possibility of loosening, thereby ensuring the reliability of the first joint 320 arranged on the handle structure 300 shell 310 and improving the service life of the first joint 320.

[0042] Referring to Figures 3 to 5, in one embodiment, the first connector 320 is provided with an insertion groove 322 connected to the card slot 321, the insertion groove 322 extends axially along the first connector 320, and the card slot 321 extends circumferentially along the first connector 320, that is, the insertion groove 322 and the card slot 321 intersect, and the two together form an L-shaped groove, so that when the first connector 320 is axially inserted into the mounting cavity 311 of the shell 310, the card bone 312 is correspondingly located in the insertion groove 322. In this position, the first connector 320 can move along its own axial direction relative to the housing 310. As the first connector 320 rotates around its own circumference, the clamping bone 312 can slide into the clamping groove 321 through the insertion groove 322, and then be clamped in the clamping groove 321. When the first connector 320 is not rotated in the opposite direction, the clamping bone 312 will not withdraw from the clamping groove 321. The clamping cooperation between the clamping bone 312 and the clamping groove 321 realizes the connection and fixation of the housing 310 and the first connector 320. At the same time, as the use time increases, when the first connector 320 needs to be replaced, through the setting of the insertion groove 322, the first connector 320 can also be rotated to withdraw from the clamping groove 321 to the insertion groove 322, thereby realizing the separation of the first connector 320 from the housing 310, and then facilitating the replacement of the first connector 320.

[0043] Referring to FIGS. 3 to 5 , in one embodiment, the first connector 320 is provided with a first blocking portion 323 and a second blocking portion 324 protruding outward in a radial direction (i.e., a direction perpendicular to the axial direction), and the first blocking portion 323 and the second blocking portion 324 surround the clamping slot 321. Thus, when the clamping bone 312 is clamped into the clamping slot 321, the first blocking portion 323 and the second blocking portion 324 abut against and limit the clamping bone 312, thereby reducing the possibility of the clamping bone 312 being separated from the clamping slot 321, thereby reducing the risk of relative movement between the first connector 320 and the housing 310, and ensuring the reliability and stability of the connection between the two.

[0044] Referring to FIGS. 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 joint 320, and another portion of the first blocking portion 323 extends axially along the first joint 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 joint 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 can also be a gap between the end of the first blocking portion and the second blocking portion, and the gap can be smaller than the width of the card bone (i.e., the size of the card bone along the axial direction) to prevent the card bone from falling out of the card slot.

[0045] Referring to FIGS. 3 to 5 , in one embodiment, along the axial direction, a limiting portion 314 is provided on the side of the clamping bone 312 away from the first joint 320, and when the clamping bone 312 is clamped in the clamping groove 321, the limiting portion 314 abuts against the side wall of the first blocking portion 323. Through this arrangement, the contact area between the first joint 320 and the housing 310 is further increased, thereby reducing the possibility of relative displacement between the joint and the housing 310, improving the connection reliability and use stability of the two, and reducing the possibility of loosening.

[0046] Referring to FIGS. 3 to 5 , in one embodiment, the slot 321 includes a plurality of slots 321, which are arranged at intervals along the circumference of the first joint 320. Correspondingly, a plurality of ribs 312 are provided, which are arranged at intervals along the circumference of the housing 310. For example, in this embodiment, there are two slots 321 and two ribs 312, the two slots 321 are evenly distributed on the first joint 320, and the two ribs 312 are evenly distributed on the housing 310. Through the cooperation of the plurality of ribs 312 and the slots 321, the contact area between the first joint 320 and the housing 310 is further increased, the possibility of relative displacement between the joint and the housing 310 is reduced, the connection reliability and use stability of the two are improved, and the possibility of loosening is reduced.

[0047] Referring to FIGS. 5 and 6 , in one embodiment, one of the first connector 320 and the wall of the installation cavity 311 is provided with an anti-foolproof rib 325, and the other is provided with an anti-foolproof groove 313 for engaging with the anti-foolproof rib 325. For example, in this embodiment, the outer wall of the first connector 320 is provided with an anti-foolproof rib 325, and the wall of the installation cavity 311 of the shell 310 is provided with an anti-foolproof groove 313. The direction in which the first connector 320 is connected to the shell 310 is limited by the anti-foolproof rib 325 and the anti-foolproof groove 313 to prevent reverse installation, thereby improving the assembly efficiency of the first connector 320 and the shell 310. In other embodiments, the setting positions of the anti-foolproof rib and the anti-foolproof groove can be interchanged, that is, the first connector is provided with an anti-foolproof groove, and the wall of the shell installation cavity is provided with an anti-foolproof rib.

[0048] Referring to Figures 3, 6 and 7, in one embodiment, the handle structure 300 also includes a second connector 330 for communicating with the negative pressure suction valve, and a portion of the second connector 330 is accommodated in the mounting cavity 311, wherein the second connector 330 is provided with a second through hole, and when the first connector 320 is docked with the second connector 330, the second through hole is connected to the first through hole of the first connector 320.

[0049] Specifically, one of the second joint 330 and the first joint 320 is provided with a stop block 331, and the other is provided with a stop groove 326 for engaging with the stop block 331. For example, in the present embodiment, the outer wall of the second joint 330 is provided with a stop block 331, and the first joint 320 is provided with a stop groove 326 facing one end of the second joint 330. Further, a plurality of stop blocks 331 and stop grooves 326 are provided at intervals, so that the first joint 320 and the second joint 330 can be quickly docked. In addition, when the first joint 320 is a straight tube and the second joint 330 is an L-shaped tube, by providing a plurality of stop blocks 331 and stop grooves 326, the interface orientation of the second joint 330 can also be conveniently adjusted to meet actual use requirements. In other embodiments, the setting positions of the stop blocks and the stop grooves can be interchanged, that is, the first joint is provided with a stop block, and the second joint is provided with a stop groove.

[0050] In the prior art, the negative pressure connector is integrated into the negative pressure suction valve, which causes the pipeline of the negative pressure suction device to interfere with the operation of the negative pressure suction valve, thereby causing inconvenience to the surgical operation. In the present application, the first connector 320 and the second connector 330 are respectively connected to the shell 310 of the handle structure 300, and 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. That is to say, the first connector 320 and the second connector 330 spatially isolate the pipeline of the negative pressure suction device from the negative pressure suction valve, thereby preventing the swing of the pipeline of the negative pressure suction device during the operation from interfering with the doctor's operation of the negative pressure suction valve, thereby reducing the difficulty of the operation and improving the convenience of the operation. Among them, the gap between the second connector 330 and the shell 310 can also be filled with an adhesive such as glue to ensure the connection effect between the second connector 330 and the shell 310.

[0051] When assembling the handle structure 300 of the endoscope, the first connector 320 is first inserted into the installation cavity 311 of the shell 310, so that the clamping bone 312 in the shell 310 is located in the insertion groove 322 of the first connector 320. During this process, the anti-crash rib 325 on the first connector 320 and the anti-crash groove 313 on the shell 310 cooperate to limit the direction, thereby preventing the first connector 320 and the shell 310 from being installed upside down. After insertion, the first joint 320 is rotated again so that the clamping bone 312 slides from the insertion groove 322 into the clamping groove 321, and the clamping bone 312 is prevented from being separated from the clamping groove 321 by the blocking and limiting of the groove wall of the clamping groove 321, thereby preventing the first joint 320 from being separated from the shell 310; the second joint 330 is then installed on the first joint 320, so that the stop block 331 on the second joint 330 is inserted into the stop groove 326 on the first joint 320, and glue is applied to the gap between the second joint 330 and the shell 310 to ensure the connection effect between the second joint 330 and the shell 310. Furthermore, the gap between the first joint 320 and the shell 310 can also be filled with glue, and the connection effect between the first joint 320 and the shell 310 is further improved by glue bonding, preventing the possibility of loosening, improving the reliability of the negative pressure suction function, and ensuring the clarity of the field of vision in the surgical area.

[0052] Furthermore, an embodiment of the present application also provides an endoscope (not shown), including the handle structure 300 of the endoscope as described above. Since the endoscope includes the handle structure of any of the above embodiments, the swing load of the pipeline of the negative pressure suction device during surgery is transmitted to the first joint through the snap-fitting of the first joint and the shell, which can reduce the problem of failure of the connection between the first joint and the shell, thereby improving the firmness of the connection between the first joint and the shell, improving the reliability of the use of the negative pressure suction function, and ensuring the clarity of the field of view in the surgical area.

[0053] It can be understood that the endoscope may further include an insertion portion (not shown) and a display device (not shown), the handle structure is connected to the insertion portion, and the handle structure is also connected to the display device. During the use of the endoscope, the insertion portion can be extended into the patient's body, and the image of the lesion area is obtained through the camera module in the insertion portion, and displayed on the display device for diagnosis or treatment.

[0054] The endoscope of this embodiment may be a disposable endoscope, a limited-time multiplex endoscope, or an unlimited-time multiplex endoscope. The endoscope of this embodiment may be a bronchoscope, a pyeloscope, an esophagoscope, a gastroscope, a colonoscope, an otoscope, a nasal mirror, a stomatoscope, a laryngoscope, a colposcope, a laparoscope, an arthroscope, etc. This embodiment does not specifically limit the type of endoscope.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
