Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to an operating handle and an endoscope. Background Technology

[0002] Endoscopes, as minimally invasive medical devices for examination and treatment, can be used to diagnose and treat a variety of diseases. Endoscopes enter the body through natural orifices or small surgical incisions, allowing doctors to clearly observe the internal condition, diagnose various diseases, and provide various adjunctive treatments. A common function of suction endoscopes is the suction of bodily fluids, blood clots, or secretions during surgery. In traditional endoscopes with suction function, the suction nozzle and suction button are integrated. Pressing the suction button opens the suction inlet, allowing the suction device to aspirate bodily fluids, blood clots, or secretions. However, this design, to better accommodate the height of the suction nozzle, results in the suction button protruding significantly above the operating handle, making it inconvenient for operators with small hands. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide an operating handle and an endoscope, which aims to solve the problem that the traditional endoscope is not user-friendly for operators with small hands because the suction button is much higher than the operating handle, and the operation is relatively inconvenient.

[0004] To achieve the above objectives, the present invention provides an operating handle, comprising:

[0005] handle body;

[0006] A suction nozzle structure is provided on one side of the handle body, and a first channel is formed within the suction nozzle structure;

A second channel communicating with the first channel is formed in the first mounting base, and the pressing member and the suction nozzle structure are spaced apart.

[0008] When the pressing member is subjected to an external force, at least part of it can undergo elastic deformation and movement, so that the pressing member can conduct the second channel and the second channel is suitable for conducting the suction pipe and the first channel; when the external force on the pressing member is removed, under the action of the elastic restoring force of the pressing member, the pressing member can be reset to block the second channel.

[0009] Optionally, the elastically deformable portion of the pressing element protrudes from the handle body; and / or,

[0010] The pressing element is arranged to move linearly back and forth, and the direction of movement of the pressing element is adapted to form an obtuse angle with the central axis of the suction pipe.

[0011] Optionally, the pressing component includes a movable rod movably sleeved within the first mounting base, a silicone head disposed at a first end of the movable rod, and a sealing portion disposed at a second end of the movable rod;

[0012] The silicone head connects the first mounting base and the movable rod. When the silicone head elastically deforms, it drives the movable rod to move, so as to have a conductive state that opens the second channel and a blocking state that blocks the second channel.

[0013] Optionally, a first mounting hole is provided on one side of the handle body, the first mounting seat is sleeved in the first mounting hole and one end extends out of the first mounting hole and forms an installation gap with the handle body, and one side of the silicone head is engaged in the installation gap.

[0014] Optionally, the silicone head has a first connecting end, a second connecting end, and an elastic arm connecting the first connecting end and the second connecting end, wherein the first connecting end is engaged within the installation gap, and the second connecting end is sleeved on the first end of the movable rod.

[0015] Optionally, the first end of the movable rod protrudes with a first boss and a second boss arranged at intervals, and the second connecting end is sleeved on the outside of the first boss and at least partially engaged in the interval between the first boss and the second boss.

[0016] Optionally, the sealing portion includes a sealing protrusion protruding from the second end of the movable rod;

[0017] The first mounting base is arranged in a ring shape with openings at both ends. When in the blocked state, the first end of the movable rod can extend from one end opening of the first mounting base in the axial direction, and the blocking protrusion blocks the other end opening of the first mounting base in the axial direction.

[0018] Optionally, a first through hole is provided on one side of the first mounting base in the circumferential direction, and the first channel communicates with the first through hole;

[0019] When in the conducting state, the opening at the other end of the first mounting base along its axial direction is open and connects the first through hole and the first channel.

[0020] Optionally, a second mounting hole is provided on the handle body, and the second mounting hole and the first mounting hole are located on the same side of the handle body; the suction nozzle structure includes:

[0021] The second mounting base is disposed in the second mounting hole and is hollow. The first channel is disposed on one side of the second mounting base and connects the second mounting base and the first mounting base.

[0022] A suction nozzle is rotatably mounted on the second mounting base, with one end connected to the second mounting base, and the other end of the suction nozzle extends out of the handle body and extends laterally along the second mounting hole.

[0023] A limiting part protrudes from the outer periphery of the suction nozzle and is located inside the handle body. The limiting part is used to limit the rotation angle of the suction nozzle.

[0024] This utility model also provides an endoscope, including the aforementioned operating handle.

[0025] The technical solution provided by this utility model has the following beneficial effects:

[0026] The operating handle provided by this utility model includes a handle body, a suction nozzle structure, and a pressing structure. The handle body can be used for the operator to hold, and the suction nozzle structure is adapted to connect to an external suction device. When the suction nozzle structure and the pressing structure are connected, fluids (such as bodily fluids, blood clots, or secretions) in the patient's body can be suctioned out through the suction nozzle structure. The pressing structure can control the opening and closing of the entire suction circuit. Specifically, by setting the pressing element to have elastic deformation, the pressing element can be moved by elastic deformation under the action of external force, so that the pressing element can be connected to a second channel, which can be connected to the suction circuit and the first channel. The fluid in the patient's body can enter the second channel along the suction circuit, flow into the first channel, and then exit the endoscope through the suction nozzle structure, thus better completing the suction of fluids in the patient's body. When it is not necessary to suction fluids, the pressing element will return to its natural state under the action of the elastic restoring force of the elastic part. At this time, the pressing element can block the second channel, and the fluid in the patient's body will not flow out. Furthermore, the travel of the pressing element is not limited by the height of the suction nozzle structure, and the setting height of the pressing element is more flexible, making it easier for operators to operate and making the use of the endoscope more convenient.

[0038] This invention provides an operating handle 100, which is suitable for endoscopes, especially endoscopes with suction function, so that the amount of fluid discharged from the patient's body can be better controlled during surgery.

[0039] Specifically, please refer to Figure 1 and Figure 2 In this embodiment, the operating handle 100 includes a handle body 1, a suction nozzle structure 2, and a pressing structure 3. The suction nozzle structure 2 is disposed on one side of the handle body 1, and a first channel 25 is formed within the suction nozzle structure 2. The pressing structure 3 includes a first mounting base 31 disposed on the handle body 1 and a pressing member 32 movably disposed on the first mounting base 31. A second channel communicating with the first channel 25 is formed within the first mounting base 31. The pressing member 32 is spaced apart from the suction nozzle structure 2. When the pressing member 32 is subjected to external force, at least part of it can undergo elastic deformation and movement, so that the pressing member 32 can conduct the second channel and the second channel is suitable for conducting the suction tube 12 and the first channel 25. When the external force on the pressing member 32 is removed, under the action of the elastic restoring force of the pressing member 32, the pressing member 32 can reset to block the second channel.

[0040] In this embodiment, the handle body 1 can be used for the operator's hand to hold, and the suction nozzle structure 2 can be adapted to connect to an external suction device. When the suction nozzle structure 2 is connected to the pressing structure 3, the fluid (such as body fluid, blood clots, or secretions) in the patient's body can be suctioned out through the suction nozzle structure 2; and the pressing structure 3 can control the opening and closing of the entire suction circuit. Specifically, by setting the pressing member 32 to have elastic deformation, the pressing member 32 moves due to elastic deformation under the action of external force. This design allows the pressing element 32 to open the second channel, which in turn connects the suction tube 12 and the first channel 25. Fluid from the patient's body can flow along the suction tube 12 into the second channel and then into the first channel 25 before exiting the endoscope through the suction nozzle structure 2, thus better facilitating the suction of fluid from the patient's body. When suction is not needed, the pressing element 32 returns to its natural state under the elastic restoring force of its elastic portion. At this time, the pressing element 32 blocks the second channel, preventing fluid from flowing out of the patient's body. Furthermore, the pressing element 32 is spaced apart from the suction nozzle structure 2, ensuring that the movement of the pressing element 32 is not related to the suction nozzle structure 2, and that the travel distance of the pressing element 32 is not limited by the suction nozzle structure 2. The height of the pressing element 32 is more flexible, making it easier for operators to use and thus more convenient for endoscope use.

[0041] Among them, such as Figure 2 As shown, the handle body 1 includes a housing 11 and a suction tube 12 disposed within the housing 11. The housing 11 is generally gun-shaped for easy hand grip. Preferably, the suction nozzle structure 2 and the pressing structure 3 are located on the same side of the housing 11, and both are located on the upper side of the housing 11, i.e., the side that is easy for the thumb to press when the hand grips the handle body 1. The elastic deformable portion of the pressing member 32 protrudes from the handle body 1. The operator can press the elastic deformable portion of the pressing member 32 to drive the pressing member 32 to move, thereby blocking and opening the second channel for suction of bodily fluids.

[0042] Preferably, the pressing member 32 is arranged to move linearly back and forth, and the moving direction of the pressing member 32 is adapted to be set at an obtuse angle with the central axis of the suction tube 12. When the pressing member 32 opens the second channel, the end of the pressing member 32 will not completely fit with the tube wall of the suction tube 12. The pressing member 32 is not likely to block the suction tube 12, ensuring that the liquid in the suction tube 12 can be better drawn out when the second channel is in the conductive state.

[0043] Preferably, combined with Figure 2 and Figure 3As shown, the pressing member 32 includes a movable rod 321 movably sleeved within the first mounting base 31, a silicone head 322 disposed at a first end of the movable rod 321, and a sealing portion 33 disposed at a second end of the movable rod 321. The silicone head 322 connects the first mounting base 31 and the movable rod 321. When the silicone head 322 elastically deforms, it drives the movable rod 321 to move, thus having a conductive state that opens the second channel and a sealing state that blocks the second channel. During operation, the operator manipulates the silicone head 322, causing it to elastically deform, thereby driving the movable rod 321 to move as well. This allows the movable rod 321 to switch between the conductive state and the sealing state, providing better control over the suction of the patient's bodily fluids.

[0044] Furthermore, a first mounting hole is provided on one side of the handle body 1, and the first mounting seat 31 is fixedly sleeved in the first mounting hole. The shape of the first mounting seat 31 is adapted to the shape of the first mounting hole. One end of the first mounting seat 31 extends out of the first mounting hole and extends laterally toward the first mounting hole to form an installation gap with the handle body 1. One side of the silicone head 322 is engaged in the installation gap, thereby positioning the silicone head 322 and limiting and fixing the silicone head 322 between the housing 11 and the first mounting seat 31, so as to better prevent the silicone head 322 from falling off.

[0045] Specifically, regarding the silicone head 322, in combination with Figure 3 and Figure 4 As shown, the silicone head 322 has a first connecting end 3221, a second connecting end 3222, and an elastic arm 3223 connecting the first connecting end 3221 and the second connecting end 3222. The first connecting end 3221 is engaged within the mounting gap to ensure that one end of the silicone head 322 can be better fixed between the housing 11 and the first mounting base 31. The second connecting end 3222 is sleeved on the first end of the movable rod 321 to ensure that the other end of the silicone head 322 can be reliably connected to the movable rod 321. Furthermore, the elastic arm 3223 can generate sufficient elastic deformation, allowing the movable rod 321 to move more effectively after the silicone head 322 deforms. This allows for better suction of fluid from the patient's body when the movable rod 321 is in the conductive state, resulting in smoother aspiration.

[0046] More preferably, such as Figure 4As shown, a first boss 3211 and a second boss 3212, spaced apart, protrude from the first end of the movable rod 321. The first mounting base 31 is generally annular with open ends, and preferably annular. The shape of the movable rod 321 matches the shape of the first mounting base 31, and the movable rod 321 is generally cylindrical, so as to be movably fitted inside the first mounting base 31. The first boss 3211 and the second boss 3212 both protrude from the outer periphery of the movable rod 321 and are arranged in parallel at intervals. Preferably, the first boss 3211 and the second boss 3212 are arranged in a complete circle around the periphery of the movable rod 321. The first protrusion 3211 is located at the end of the first end of the movable rod 321. The second connecting end 3222 is sleeved on the outside of the first protrusion 3211 and is at least partially engaged in the gap between the first protrusion 3211 and the second protrusion 3212. On the one hand, the silicone head 322 can cover the end of the movable rod 321, making the operator feel better when pressing. On the other hand, it can make the silicone head 322 reliably connected to the movable rod 321, ensuring that the silicone head 322 will not come loose after multiple presses.

[0047] It is understood that when the first mounting base 31 is configured with openings at both ends, the inner side of the first mounting base 31 forms the second channel. Therefore, by blocking and opening one end of the first mounting base 31 located inside the handle body 1, the second channel can be blocked and opened. Specifically, the blocking part 33 includes a blocking protrusion 331 protruding from the second end of the movable rod 321; when in the blocking state, such as Figure 4 As shown, the first end of the movable rod 321 can extend from one axial end opening of the first mounting base 31, allowing at least a portion of the silicone head 322 and the movable rod 321 to extend outside the housing 11 for easy operation. Simultaneously, the sealing protrusion 331 seals the other axial end opening of the first mounting base 31, thereby blocking the second channel. When suction is required, the operator can press the end of the movable rod 321, causing the silicone head 322 to elastically deform. Simultaneously, the sealing part 33 opens the end opening of the first mounting base 31, connecting the second channel with the suction tube 12 inside the housing 11. Fluid from the patient's body can then enter the second channel through the suction tube 12, and after entering the first channel 25, be discharged through the suction nozzle structure 2. When the operator releases the movable rod 321, the elastic restoring force of the silicone head 322 drives the movable rod 321 back to its original position, and the sealing part 33 re-seals the end opening of the second channel.

[0048] Moreover, such as Figure 4 As shown, an installation groove is provided on the outer periphery of the sealing protrusion 331, and the pressing structure 3 also includes a first sealing ring 34. The first sealing ring 34 is fitted into the installation groove, so that when the movable rod 321 is in the sealing state, the sealing effect is better and it is not easy to form liquid leakage.

[0049] A first through hole is provided on one circumferential side of the first mounting base 31, and the first channel 25 is connected to the first through hole. When in the conductive state, the opening at the other end of the first mounting base 31 along its axial direction is open and connects the first through hole and the first channel 25. That is, when the movable rod 321 is in the conductive state, the fluid in the patient's body can enter the second channel through the suction tube 12, flow through the first through hole to the first channel 25, and flow out through the self-suction nozzle structure 2.

[0050] There are several ways to form the first channel 25. The first channel 25 can be formed in a connecting pipe, or it can be enclosed by the internal structure of the suction nozzle structure 2. Preferably, the suction nozzle structure 2 further includes a guide pipe, one end of which is inserted into the first through hole, and the other end of which is in communication with the suction nozzle structure 2.

[0051] Furthermore, a second mounting hole is provided on the handle body 1. The second mounting hole and the first mounting hole are located on the same side of the handle body 1 to facilitate observation of the working status of the suction nozzle structure 2 when operating the pressing structure 3. Specifically, in conjunction with Figure 2 and Figure 4 As shown, the suction nozzle structure 2 includes a second mounting base 21, a suction nozzle 22, and a limiting part 23. The second mounting base 21 is disposed within a second mounting hole and is hollow. The first channel 25 is disposed on one side of the second mounting base 21 and connects the second mounting base 21 and the first mounting base 31. The suction nozzle 22 is rotatably mounted on the second mounting base 21, with one end connected to the second mounting base 21. The other end of the suction nozzle 22 extends out of the handle body 1 and extends laterally along the second mounting hole, so that the suction nozzle 22 can better connect with the external suction device from different angles. The limiting part 23 protrudes from the outer periphery of the suction nozzle 22 and is located inside the handle body 1. The limiting part 23 is used to limit the rotation angle of the suction nozzle 22 to prevent the suction nozzle 22 from rotating 360° and causing entanglement of the guide tube.

[0052] Preferably, the rotation angle of the suction nozzle 22 is 180°, and a limiting groove is provided on the inner side of the housing 11 corresponding to the second mounting hole. The limiting part 23 includes a limiting protrusion 231 protruding from the outer periphery of the suction nozzle 22. The limiting protrusion 231 abuts against the limiting groove to control the rotation angle of the suction nozzle 22.

[0053] Furthermore, a second sealing ring 24 is provided between the suction nozzle 22 and the second mounting base 21. The second sealing ring 24 can prevent external dirt from entering the inside and can also prevent liquid from leaking between the suction nozzle 22 and the second mounting base 21.

[0054] This utility model also provides an endoscope, which includes the aforementioned operating handle 100. The operating handle 100 makes suction operations easier during use, better meeting the usage habits and methods of different users, resulting in smoother operation and thus smoother surgical procedures, thereby improving surgical efficiency.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
