[0032] First embodiment

[0033] Please refer to Figure 1 and Figure 2 This embodiment provides a handle device, including a housing 100 and a slide bar 200 fixed on the housing 100, wherein a rotating shaft 300 capable of sliding along the axis direction of the sliding bar 200 is disposed in the housing 100, a rotating wheel 400 capable of rotating synchronously with the rotating shaft 300 is disposed in the housing 100, and a slideway 430 is disposed at one end of the rotating wheel 400 along the axis direction, and one end of the rotating shaft 300 penetrates into the slideway 430;

[0034] The rotating shaft 300 is provided with a guide wire installation position 330 , and the housing 100 or the sliding rod 200 is provided with a guide wire through hole 110 , and the axis of the guide wire through hole 110 coincides with the axis of the rotating shaft 300 .

[0035] The handle device provided in this embodiment is used to control instruments such as biopsy forceps, tissue forceps, foreign body forceps, hemostatic clips, snares, etc. Specifically, taking the control of tissue forceps as an example, one end of the guide wire is connected to the rotating shaft 300, and the other end of the guide wire is connected to the clamp of the tissue forceps. The rotation of the rotating wheel 400 will drive the rotating shaft 300 to rotate, and then drive the rotation of the tissue forceps through the guide wire. Therefore, the rotation of the tissue forceps can be controlled without rotating the entire handle device; when it is necessary to control the opening and closing of the tissue forceps, the rotating shaft 300 can be slid along the slide bar 200. Since the rotating shaft 300 can slide in the slideway 430, the existence of the rotating wheel 400 will not hinder the sliding of the rotating shaft 300. The handle device in this application is more convenient in the operation of the rotation function and axial sliding, and the operation is more in line with ergonomics.

[0036] Second embodiment

[0037] Based on the first embodiment, this embodiment further defines that: the rotating wheel 400 includes a rotating shaft 410 and a rotating dial 420 sleeved on the rotating shaft 410, the slideway 430 is located in the middle of the rotating shaft 410, and the housing 100 is provided with an operation port 120 at a position corresponding to the circumference of the rotating dial 420, such as Figure 3 shown.

[0038] Specifically, in this embodiment, the housing 100 is provided with an operation port 120, and the number of the operation ports 120 is two, and the two operation ports 120 are symmetrically arranged along the axis of the rotating wheel 400. In some other embodiments, the number of the operation ports 120 may also be one or more. The location of the operation port 120 corresponds to the circumference of the rotating dial 420, so that when the operator needs to rotate the shaft 300, the operator can rotate the rotating wheel 400 through the operation port 120, which is convenient for controlling the rotating wheel 400. When there are two operation ports 120 and they are symmetrically arranged along the axis of the rotating wheel 400, it is more convenient to rotate the rotating wheel 400.

[0039] It should be noted that the rotating dial 420 and the rotating shaft 410 in this embodiment can be fixedly connected or integrally formed, wherein the rotating shaft 410 is coaxially arranged with the rotating shaft 300, and in order to facilitate the operator's control, the outer surface of the rotating dial 420 can be provided with protrusions, grooves or patterns to increase the friction between the outer surface and the operator's hand.

[0040] In some embodiments, a rotating dial wheel 420 installation position is disposed in the housing 100 , and installation holes for the rotating shaft 410 to extend into are disposed on both sides of the rotating dial wheel 420 installation position.

[0041] In this embodiment, a cavity for mounting a rotating dial 420 is provided in the housing 100, and mounting holes are provided on both sides of the cavity. The rotating shafts 410 at both ends of the rotating dial 420 extend into the corresponding mounting holes respectively. In order to avoid the mounting holes hindering the rotation of the rotating dial 420 or the rotating shaft 410, the aperture of the mounting hole should be slightly larger than the outer diameter of the rotating shaft 410, so that the mounting holes can achieve axial limitation of the rotating dial 420 and the rotating shaft 410 without affecting the rotation of the rotating shaft 300 driven by the rotating dial 420.

[0042] In some embodiments, the cross-section of the slide 430 along the direction perpendicular to the axis is non-circular, and a synchronous rotation structure 320 is provided at one end of the rotating shaft 300 extending into the slide 430, and the cross-sectional size and shape of the synchronous rotation structure 320 along the direction perpendicular to the axis are adapted to the cross-sectional size and shape of the slide 430 along the direction perpendicular to the axis.

[0043] In this embodiment, since the rotating shaft 300 and the slide 430 need to rotate synchronously, the cross-section of the slide 430 cannot be circular, and specifically can be elliptical or square. In some embodiments, a positioning edge can also be set axially on the inner wall of the slide 430. In this case, the synchronous rotation structure 320 can include a positioning groove adapted to the positioning edge.

[0044] Third embodiment

Figure 4 and Figure 5 shown.

[0046] In this embodiment, the rotating shaft 300 is provided with an annular mounting groove 310, and the second sliding portion 520 of the push ring 500 extends into the annular mounting groove 310. When the rotating shaft 300 is driven by the rotating wheel 400 to rotate, the second sliding portion 520 can slide along the annular mounting groove 310, so that the push ring 500 does not need to rotate relatively along the slide bar 200. In addition, the slide bar 200 is provided with a slide groove 210. When the rotating shaft 300 needs to slide along the slide bar 200, the push ring 500 can drive the rotating shaft 300 to slide along the slide groove 210. Specifically, there can be one slide groove 210, or more than two slide grooves 210. In this embodiment, there are two slide grooves 210, which are respectively provided on both sides of the axis of the slide bar 200.

[0047] In some embodiments, the push ring 500 includes a shaft connecting through hole 530 , the second sliding portion 520 is disposed on the inner wall of the shaft connecting through hole 530 , and a slide rod connecting through hole 540 is disposed on the outer side of the shaft connecting through hole 530 .

[0048] In this embodiment, the two slide grooves 210 can divide the slide rod connecting hole 540 into two parts, and the rotating shaft connecting hole 530 is located in the middle of the two parts, so that the push ring 500 can drive the rotating shaft 300 to move axially without hindering the rotation of the rotating shaft 300. Specifically, the two parts of the slide rod connecting hole can form a square, circle, ellipse, etc., and the specific shape is adapted to the cross-sectional shape of the slide rod.

[0049] In some embodiments, axial push-pull rings 550 are provided on both sides of the push ring 500 to facilitate operation by operators.

[0052] Specifically, the guide wire through hole 110 is located at the bottom of the mounting hole and communicates with the mounting hole, so that the guide wire can pass through the housing and connect with the tissue forceps, etc. A hand ring 220 is provided at one end away from the guide wire through hole 110 to facilitate fixing or supporting the housing and the slide rod 200 as a whole.

[0053] In an optional embodiment, the housing 100 is provided with a mounting groove for the slide bar 200, and one end of the slide bar 200 is inserted into the mounting groove for the slide bar 200. Specifically, in this embodiment, the housing 100 and the mounting groove can be fixed by an existing connection method, such as interference fit.

[0054] In an optional embodiment, the housing 100 includes a first half shell and a second half shell that are spliced ​​together, and the installation slot of the slide bar 200 includes two half slots that are arranged opposite to each other, and each half slot has a portion located in the first half shell and another portion located in the second half shell. In this structure, the slide bar 200 can be fixed to the first half shell and the second half shell at the same time, which can improve the stability of the structure and facilitate installation; in addition, the first half shell and the second half shell can be connected by a bayonet connection, and screw holes can be set to fix them by screws.

[0055] Specifically, when assembling the handle in this embodiment, the rotating wheel 400 can be installed in the outer shell 100 first, and then the rotating shaft 300 and the push ring 500 can be pre-installed together, and then the rotating shaft 300-push ring 500 assembly can be installed in the outer shell 100 with the rotating wheel 400, and finally the slide bar 200 can be installed in the slide bar 200 installation groove through the slide bar connecting hole 540.
