[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the medical device handle provided in this embodiment of the present invention includes: a handle frame and a control component mounted on the handle frame; the handle frame includes: an opening frame 100 and a fastener 200 movably mounted on the opening frame 100; the opening frame 100 has a clamping opening 101 and a side opening 102 communicating with the clamping opening 101; the fastener 200 is used to drive the side opening 102 to retract and reduce the radial dimension of the clamping opening 101.

[0029] In an optional embodiment, the medical device handle is used to operate the operating end of a medical device, such as an endoscope, surgical instrument, or other minimally invasive treatment device. The side opening 102 provides the clamp 101 with a certain elastic deformation space, facilitating changes in the radial dimension of the clamp 101. A fastener 200 is movably mounted on the opening frame 100 and correspondingly positioned to the side opening 102. Adjusting the fastener 200 applies force to the width of the side opening 102, causing it to contract. When the side opening 102 contracts, the radial dimension of the clamp 101 decreases, thereby achieving the clamping function of the clamp 101 on the held component.

[0030] Specifically, the fastener 200 can be a threaded connection structure, such as a bolt and nut assembly, or a quick-release structure such as an elastic snap-fit ​​structure or a sliding locking structure. For example, in one embodiment, the fastener 200 includes an adjusting bolt and a threaded hole provided on the opening bracket. Rotating the adjusting bolt moves it towards the side opening, thereby pushing the elastic arms on both sides of the side opening inward, which in turn causes the inner diameter of the clamp 101 to decrease, achieving clamping.

[0031] In this embodiment of the invention, the fastener 200 includes a rod 210 and a knob 220 threadedly engaged with the rod 210. The rod 210 is hinged to one side wall of the side opening 102, and the other side wall of the side opening 102 has a notch 103 corresponding to the rod 210. This increases the pitch of the thread on the rod 210. The knob 220, threadedly engaged with the rod 210, allows for increased axial movement of the knob 220 with fewer rotations (smaller rotation angles), thereby improving the efficiency of assembling and disassembling the medical device handle.

[0032] See Figure 1 , Figure 2 and Figure 13 When the rod 210 disengages from the notch 103 and the side opening 102 is fully open, the conical rod 010 of the endoscope can be inserted into the clamp 101 through the side opening 102. Subsequently, the rod 210 is rotated and placed into the notch 103, and the knob 220 is tightened. The knob 220 compresses the side wall of the side opening 102, thereby reducing the width of the side opening 102 and clamping the conical rod 010 into the clamp 101.

[0033] In an optional embodiment, the other sidewall of the side opening 102 is provided with a limiting portion adapted to the knob 220; the knob 220 engages with the limiting portion, keeping the rod 210 within the notch 103. The limiting portion can be configured as a groove to accommodate the knob 220, or it can be configured as a wedge or similar element to prevent the knob 220 from sliding along the extension direction of the notch 103. When the rod 210 is rotated and positioned within the notch 103, the limiting portion prevents the knob 220 from sliding along the extension direction of the notch 103, thereby keeping the rod 210 within the notch 103.

[0034] See Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 The limiting part includes a boss 104 located on the other side wall of the side opening 102 and protruding outward; the knob 220 is provided with a circular groove 201 that matches the boss 104. When the knob 220 is locked, the boss 104 fits into the circular groove 201, which ensures that the knob 220 can still rotate smoothly, and prevents the knob 220 from sliding and loosening relative to the opening frame 100, and keeps the rod 210 in the notch 103.

[0035] Furthermore, the diameter of the boss 104 decreases from the root to the tip, or the diameter of the circular groove 201 decreases inward from the opening. Alternatively, the diameter of the boss 104 can decrease from the root to the tip, and the diameter of the circular groove 201 can decrease inward from the opening. As the knob 220 is tightened, the boss 104 engages with the circular groove 201, and coaxial alignment is achieved through pressing.

[0036] In an optional embodiment, the end of the rod 210 is provided with a flange 211 or a limiting cap 212 to prevent the knob 220 from falling off the rod 210. The knob 220 may have a non-metallic shell and a core embedded within the non-metallic shell, with the core threadedly engaging the rod 210. The end of the rod 210 where the knob 220 is mounted has a flange 211 that increases its radial dimension; alternatively, the limiting cap 212 is mounted on the end of the rod 210 where the knob 220 is mounted via a threaded engagement or snap-fit ​​connection. The flange 211 or the limiting cap 212, with a diameter larger than the inner diameter of the threaded hole in the core, prevents the knob 220 from falling off the rod 210.

[0037] See Figure 1 and Figure 13A first limiting protrusion 105 is provided on one side wall of the side opening 102, and a second limiting protrusion 106 is provided on the other side wall of the side opening 102. The first limiting protrusion 105 and the second limiting protrusion 106 are arranged opposite to each other and extend towards each other. When the tapered rod portion 010 is placed inside the side opening 102, the first limiting protrusion 105 and the second limiting protrusion 106 can abut against the tapered rod portion 010, thereby preventing the tapered rod portion 010 from coming out of the side opening 102.

[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the handle frame also includes: a first arm 300 and a second arm 400 connected to the opening frame 100; the first arm 300 and the second arm 400 are spaced apart; the control element includes a reel 500 rotatably connected between the first arm 300 and the second arm 400. The reel 500 can be used with an external control cable, for example, for adjusting the equipment angle, controlling the movement of accessories, etc. The rotation of the reel 500 can be manually operated by the user, or it can be automatically controlled in conjunction with an electric drive mechanism; the specific control method can be designed according to the actual application scenario.

[0039] In an alternative implementation, the opening frame 100, the first boom 300, and the second boom 400 can be integrally formed, thereby reducing production and assembly costs.

[0040] like Figure 4 and Figure 5 As shown, the open frame 100 is connected to a limiting member 600. The spool 500 is provided with multiple positioning parts 501, which are spaced apart circumferentially along the spool 500. The limiting member 600 and the positioning parts 501 are adapted to each other, and at least one of them is elastic, so that the multiple positioning parts 501 can be separably engaged with the limiting member 600 one by one during the rotation of the spool 500. When the limiting member 600 is engaged with one of the positioning parts 501, the rotation of the spool 500 can be locked. When an external force drives the spool 500 to rotate and overcomes the elastic force to disengage the limiting member 600 from one of the positioning parts 501, the limiting member 600 will engage with another positioning part 501 as the spool 500 rotates.

[0041] Furthermore, the medical device handle also includes a support platform 700; at least one of the first arm 300 and the second arm 400, as well as the opening frame 100, are connected to the support platform 700; a limiting member 600 is connected to the support platform 700, and the support platform 700 allows the limiting member 600 to be closer to the reel 500, and the support platform 700 can reinforce the connection of the opening frame 100 to the first arm 300 or the second arm 400.

[0042] At least one of the first boom 300 and the second boom 400 is connected to an anti-slip portion 800 extending toward the opening frame 100. The anti-slip portion 800 may be configured with raised or recessed textures to prevent slippage when touched.

[0043] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 10 As shown, the open frame 100 is connected to a sheath joint 900. The sheath joint 900 has a pipe hole, the axis of which coincides with or is parallel to the other tangent of the spool 500. The pull line 014 is connected to and wound around the spool 500, and the pull line 014 can extend to the far end through the sheath joint 900. The pull line 014 can be tightened by rotating the spool 500. The pull line 014 extending from the sheath joint 900 to the spool 500 coincides with or is parallel to the other tangent of the spool 500, thereby ensuring that the pull line 014 slides smoothly along the sheath joint 900.

[0044] See Figure 10 and Figure 11 As shown, a sealing ring 901 is provided inside the sheath connector 900. The pull wire 014 of the transmission connecting pulley 500 passes through the pipe hole and is press-fitted with the sealing ring 901. While the pull wire 014 is pulled towards the proximal end to control the actuator, the sealing ring 901 can seal the gaps around the pull wire 014, thereby preventing air leakage from the sheath connector 900 and the plastic-sealed spring tube 013 connected to the sheath connector 900.

[0045] like Figure 1 , Figure 10 and Figure 13 As shown, the endoscope combination device provided in this embodiment of the present invention includes: an endoscope, an actuator, and a medical device handle as described in the above embodiments; the handle of the endoscope has a conical rod portion 010 that can be detachably installed in the clamp 101; the actuator is installed at the head end of the endoscope, and the actuator is connected to the control component in a transmission manner.

[0046] In an optional implementation, the actuator can be configured as a minimally invasive treatment device such as a suture device or a clamp, and the control element can be a flexible shaft, a connecting rod, or a pull wire to control and drive the actuator.

[0047] See Figure 11 and Figure 12In this embodiment of the invention, the actuator includes: an end cap 011 and several loops 012; the end cap 011 is sealed and installed at the distal end of the endoscope, and the end cap 011 has a sheath tube 111 extending from the outside to the inside, and a plastic-sealed spring tube 013 is sealed between the sheath tube 111 and the handle frame; several loops 012 are sequentially sleeved on the end cap 011 along the axial direction, and a pull wire 014 is threaded through the plastic-sealed spring tube 013, one end of the pull wire 014 is connected to the control component, and the other end of the pull wire 014 extends from the inside of the end cap 011 to the distal end and is drively connected to the several loops 012. On the one hand, the plastic-sealed spring tube 013 is self-sealing, which can prevent gas or other fluids from leaking through the plastic-sealed spring tube 013; on the other hand, the gap between the proximal end of the plastic-sealed spring tube 013 and the pull wire 014 can be sealed by a sealing ring 901, thereby preventing the interior of the plastic-sealed spring tube 013 from becoming a channel for gas or tissue fluid leakage. The endoscope's clamp channel 015 can serve as a negative pressure suction channel, allowing lesions such as polyps or varicose veins to be drawn into the end cap 011. Subsequently, the released ligature ring 012 can be used to ligate the lesion site.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
