It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] Reference Figures 1 to 7 As shown, the present application discloses an endoscope, which includes an endoscope handle, wherein the endoscope handle includes a housing 100, a mounting bracket 200, an operating module 300, an adjustment module 400 and a suction module 500, wherein the housing 100 is provided with a mounting cavity 110; the mounting bracket 200 is mounted on the mounting cavity 110; the operating module 300 can be detachably mounted on one end of the mounting bracket 200 and pass through the housing 100; the adjustment module 400 is mounted on the mounting bracket 200, and the working end of the adjustment module 400 is connected to the input end of the operating module 300; the suction module 500 is mounted on the mounting bracket 200; and the suction module 500 is connected to the operating module 300. The mounting bracket 200 is a flat plate structure, wherein in order to adapt to the installation of different components, it can be bent to adapt to different installation components. The housing 100 may be designed as a housing of a conventional endoscope, and the operating module 300, the adjusting module 400 and the suction module 500 may also be common modules, thus reducing the production cost.

[0033] It should be noted that in order to add other functions, such as a biopsy function, a mounting position can be reserved on the mounting bracket 200, and the mounting position of the biopsy module can be adapted on the housing 100. In the present application, the operating module 300 includes an insertion tube, a curved portion connected to the insertion tube, and a head end connected to the curved portion. The insertion tube has a built-in light beam, an image signal transmission cable, a working channel, a water jetting channel, an adjustment rope, and a spring tube; the curved portion has a built-in snake bone, which is pulled by the adjustment rope to achieve bending; the head end has a built-in image sensor, a light beam, a working channel, and a water jetting hole. The adjustment rope is connected to the output end of the adjustment module 400, so that the operator can adjust the adjustment rope through the adjustment module 400 to achieve relative movement of the snake bone inside the curved portion, thereby achieving bending of the curved portion.

[0034] In some possible implementations, in order to facilitate the installation of the operating module 300, a holder 250 is provided on one end of the mounting bracket 200, and the operating module 300 is mounted on the holder 250 and the output end passes through the housing 100. More specifically, a mounting head is provided at the end of the insertion tube, and the mounting head is mounted on the holder 250, and the outward end of the insertion tube is located outside the housing 100. In addition, in some embodiments, in order to facilitate manufacturing, assembly and transportation, a hook is also provided on the mounting bracket 200, the main purpose of which is to facilitate the mounting bracket 200 to be hung up in the production line and follow the production line to enter different processing stations.

[0035] The endoscope handle is designed with a mounting bracket 200 based on the traditional housing 100, and the operating module 300, the adjustment module 400 and the suction module 500 are all mounted on the mounting bracket 200, which is convenient for workers to operate. After all the parts are mounted on the mounting bracket 200, all the assemblies are directly and synchronously mounted on the housing 100, which greatly improves the operating space and installation flexibility of the operator and improves the assembly efficiency. At the same time, all the parts are mounted on the mounting bracket 200, which can relatively fix the relative positions of all the parts to a large extent, avoiding installation errors during the installation process.

[0036] See also Figures 3 to 5 In the present application, in order to facilitate disassembly and assembly, the housing 100 includes a first cover 130 and a second cover 140, which are buckled together to form the installation cavity 110. The first cover 130 and the second cover 140 are connected in a buckled manner, which can facilitate on-site disassembly and assembly and reduce the difficulty of assembly. The first cover 130 is provided with a positioning column 150, and the mounting bracket 200 is movably inserted on the positioning column 150. The first cover 130 and the second cover 140 are both provided with a limit block for supporting the mounting bracket 200. In fact, in the actual installation process, the mounting bracket 200 is fixed by two limit blocks on the first cover 130 and the second cover 140 to prevent it from moving in the housing 100 after the first cover 130 and the second cover 140 are firmly buckled. In fact, a number of card seats are provided on the first cover 130 or the second cover 140, and the mounting bracket 200 is clamped on the card seat, which reduces the trouble of fixing with screws.

[0037] See also Figures 2 to 5In order to facilitate operation, the adjustment module 400 includes an adjustment wheel 410 and two groups of operating ropes 420; the adjustment ends of the two groups of operating ropes 420 are respectively connected to the two sides of the outer periphery of the adjustment wheel 410, and the operating ends of the two groups of operating ropes 420 are simultaneously connected to the input end of the operation module 300; the adjustment wheel 410 is clamped on the mounting bracket 200 and can rotate relative to the mounting bracket 200, and the mounting bracket 200 is provided with two groups of wire limiting blocks 210, each of which is provided with a limiting groove 220, and the two groups of operating ropes 420 are respectively movably clamped in the limiting groove 220 on the corresponding side. Among them, the adjustment wheel 410 is provided with two clamping slots, and one end of the operation of the two operating ropes 420 is connected to a fixed head, and the fixed head is clamped in the corresponding clamping slot. Among them, the operator can drive the corresponding two sides of the operating ropes 420 to move by rotating the adjustment wheel 410, and then drive the adjustment ropes in the operation module 300 to move. In addition, the limiting groove 220 can not only limit the movable position of the operating rope 420 , but also adjust the direction of the operating rope 420 to a certain extent so that it adapts to the movement of the entire adjusting wheel 410 .

[0038] In some possible implementations, for ease of operation, a driving handle 430 is provided on the adjusting wheel 410, and a driving hole 120 is provided at a position of the housing 100 corresponding to the driving handle 430, and an end of the driving handle 430 that is operated movably extends out of the driving hole 120. A semi-ring stopper is provided on the driving handle 430, which can effectively block the driving hole 120, so that when the adjusting wheel 410 rotates, the outer wall of the semi-ring stopper always abuts against the inner wall of the driving hole 120, ensuring that the inner wall of the entire housing 100 is closed. It should be supplemented that the driving hole 120 is an arc-shaped slot hole, which facilitates the movement of the driving handle 430.

[0039] In some possible implementations, in order to facilitate the movement of the two groups of operating ropes 420 and avoid being clamped by the limiting groove 220, in one embodiment of the present application, a capillary steel sleeve is sheathed on the operating rope 420, wherein the capillary steel sleeve is fixedly clamped by the limiting groove 220, and the operating rope 420 can move relative to the capillary steel sleeve. Such a design can prevent the operating rope 420 from cutting the limiting groove 220 to a certain extent, so as to effectively protect the limiting groove 220. The capillary steel sleeve is arranged on one end of the operating rope 420 close to the operating module 300.

[0040] It should be noted that in the above design, the adjustment module 400 is installed on one side of the mounting bracket 200, and the attraction module 500 can be installed on the other side. Such a design can effectively utilize the space. Of course, in some embodiments, the attraction module 500 can also be installed on both sides of the mounting bracket 200 at the same time, that is, the mounting bracket 200 can be provided with a notch structure, and the attraction module 500 bypasses the notch structure and enters the other side of the mounting bracket 200. Such a design can effectively utilize the installation space and clamp the attraction module 500 at the same time.

[0041] See also Figures 2 to 5 In some possible implementations, the suction module 500 includes a suction seat 510 and a connecting pipe 520, the suction seat 510 is clamped on the mounting bracket 200, one end of the connecting pipe 520 is connected to the connecting end on the suction seat 510, and the other end of the connecting pipe 520 is connected to the input end of the operation module 300 through a three-way joint 530, the three-way joint 530 is clamped on the mounting bracket 200, and the remaining interface of the three-way joint 530 passes through the shell 100, and the outward end of the suction seat 510 is placed on the shell 100 and communicated with the outside of the shell 100. The suction module 500 adopts a detachable module, which is convenient for workers to install and process; at the same time, the connecting pipe 520 is a silicone hose, which is convenient for adapting to the shape of the mounting bracket 200 and reducing the difficulty of installation. In this application, the suction seat 510 is actually clamped in the shell 100 through a clamping head structure. A clamping head structure is also provided on the three-way joint 530 for easy clamping.

[0042] See also Figure 6 and Figure 7 In some possible implementations, in order to ensure the sealing and the stability of the subsequent installation, the part of the suction seat 510 located outside the shell 100 forms an anti-falling baffle ring 540, and the suction seat 510 is detachably mounted with a negative pressure suction head 550, and a positioning rib 560 is provided on the outward end of the suction seat 510, and a rubber piece is installed at one end of the negative pressure suction head 550, and a positioning slot 570 for matching the positioning rib 560 is provided on the rubber piece. Among them, the negative pressure suction head 550 is a configuration structure, which is used to adapt to the suction seat 510. In addition, in the present application, the suction seat 510 is made of plastic material, which has a certain elasticity. When the negative pressure suction head 550 is installed on the suction seat 510, the sealing is achieved by the positioning rib 560 being inserted into the positioning slot 570, and secondly, the anti-falling baffle ring 540 can fit tightly with the outer wall of the shell 100.

[0043] See also Figure 3 and Figure 6The mounting bracket 200 is provided with a mounting position 240, on which a PCB circuit board 600 can be detachably mounted, and a TYPE-C connector 610 is provided on the PCB circuit board 600, and the TYPE-C connector 610 passes through the housing 100.

Such a design can effectively protect the PCB circuit board 600.

[0044] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
