Description

Technical Field

[0001] This invention relates to the field of endoscopy technology, and more particularly to an endoscope handle and an endoscope. Background Technology

[0002] As a commonly used medical device, the sputum suction endoscope can perform functions such as suctioning, washing, and retrieval. Suctioning refers to the negative pressure suction function, which is used to aspirate viscous sputum, bloody secretions, and mixed fluids after irrigation. Washing refers to the irrigation function, which injects pre-warmed saline into the body cavity to soften and aspirate viscous sputum plugs / crusts. Retrieval refers to removing samples from the body cavity, which can be done through negative pressure suction or by surgical instruments.

[0003] To achieve functions such as suctioning, washing, and retrieval, multiple interfaces are typically integrated into the suction endoscope, corresponding to the negative pressure source, irrigation fluid source, and surgical instrument insertion. However, in the process of developing this invention, the applicant discovered that for the interface connected to the irrigation fluid source, in order to control the flow of the irrigation fluid, the existing technology adds a rotary switch to the irrigation fluid source interface. This requires the operator to hold the endoscope handle with one hand and operate the rotary switch with the other, which limits the operator's operational flexibility. Summary of the Invention

[0004] The purpose of this application is to provide an endoscope handle and an endoscope, at least to solve the technical problem of limited operational flexibility caused by rotary switches.

[0005] This application is implemented as follows: In a first aspect, this application provides an endoscope handle, comprising: The housing has a gripping part and an operating component, the operating component being close to the gripping part, and a mounting part being provided at the far end of the housing. The mounting part has a through hole along the axial direction for inserting an insertion part, and a first mounting groove is provided on the outer peripheral wall of the mounting part. The adapter has a first connecting part at its distal end, which is used to connect with the insertion part, and a second connecting part at its proximal end, which is used to connect with the housing. The proximal end of the adapter has a groove, and the mounting part is located in the groove. A second mounting groove is provided on the inner wall of the groove. The second mounting groove corresponds to the first mounting groove, and the second mounting groove and the first mounting groove form a sliding cavity. A sliding body is slidably disposed in a sliding cavity along the axial direction. The sliding body is provided with a first connecting hole. The adapter is provided with a connecting channel. The first connecting hole is used to realize the communication between the connecting channel and the insertion part. The sliding body is connected to the operating component through a linkage component. The operating component is used to control the sliding body to slide along the through hole axially in the sliding cavity, so as to realize the adjustment of the communication opening between the first connecting hole and the connecting channel.

[0006] Secondly, this application provides an endoscope, including an insertion part and the aforementioned handle. The proximal end of the insertion part passes through a through hole, and a second connecting hole is provided on the peripheral wall of the insertion part. The second connecting hole corresponds to a connecting channel, and the first connecting hole is used to realize communication between the connecting channel and the second connecting hole.

[0007] The technical solution provided in this application can achieve the following beneficial effects: This application integrates the fluid channel on / off control structure at the connection between the insertion part and the handle, allowing the on / off control structure to pre-position the connection between the insertion part and the handle. The connection structure between the insertion part and the handle protects the channel control structure. By placing the operating part of the on / off control structure close to the grip, it is possible to control the fluid channel on / off with one hand, reduce the increase or decrease in the size of the endoscope space caused by the channel control structure, reduce the risk of accidental activation of the channel control structure, improve the safety of endoscope use, increase the convenience of endoscope assembly and production, and reduce production costs.

[0011] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0012] In the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] In various embodiments of this application, "proximal end" and "distal end" refer to the position of the endoscope and its accessories relative to the user in the usage environment. The end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "distal end".

[0014] Existing flexible endoscopes, in order to meet the needs of processing samples within body cavities, require the establishment of fluid channels on the endoscope. These fluid channels are used to perfuse, dilute, or perform negative pressure aspiration of the samples within the body cavity. To reduce the cost of endoscopes, current technology generally adds a commercially available standard rotary switch directly to the fluid channel interface of the endoscope. However, this rotary switch design has several drawbacks. First, it requires the operator to hold the endoscope handle with one hand and operate the rotary switch with the other, limiting the operator's flexibility. Second, the rotary switch's horizontal placement on the endoscope handle not only increases the lateral size of the endoscope product, raising packaging and transportation costs, but also increases the risk of accidental activation during use (such as when rotating the endoscope handle circumferentially to adjust the insertion direction of the insertion part), thus increasing surgical risks.

[0015] Therefore, this application provides an endoscope handle and an endoscope, in which the fluid channel on / off control structure is integrated and set at the connection between the insertion part and the handle. The on / off control structure pre-positions the connection between the insertion part and the handle, while the connection structure between the insertion part and the handle protects the channel control structure. With the operating part of the on / off control structure set close to the grip, it can realize one-handed operation of the fluid channel on / off control, reduce the increase or decrease in the size of the endoscope space caused by the channel control structure, reduce the risk of accidental activation of the channel control structure, improve the safety of endoscope use, increase the convenience of endoscope assembly and production, and reduce production costs, as specifically described in the following embodiments.

[0016] Example 1

[0017] This embodiment provides an endoscope, such as Figure 1 As shown, the endoscope includes a handle and an insertion part 400. The insertion part 400 has an instrument channel along the axial direction. The proximal port of the instrument channel can be located on the handle. There can be one or more proximal ports of the instrument channel. The distal port of the instrument channel is located at the distal end of the insertion part 400. The instrument channel is used to allow surgical instruments, irrigation fluid, or negative pressure aspiration fluid to pass through. The surgical instruments are existing technologies and can be injection needles, dilators, stents, stone retrieval baskets, optical fibers, biopsy forceps, hemostatic clips, etc., without specific limitations. The irrigation fluid can be physiological saline, a drug, or a gas, without specific limitations.

[0018] like Figures 2-10 As shown, the endoscope handle includes: The housing 100 is provided with a gripping part 110 and an operating member 120. The operating member 120 is close to the gripping part 110. The far end of the housing 100 is provided with a mounting part 130. The mounting part 130 is provided with a through hole 131 along the axial direction. The through hole 131 is used to pass through the insertion part 400. The outer peripheral wall of the mounting part 130 is provided with a first mounting groove 132. The adapter 200 has a first connecting portion 210 at its distal end, which is used to connect with the insertion portion 400. The adapter 200 also has a second connecting portion 220 at its proximal end, which is used to connect with the housing 100. The adapter 200 has a groove 240 at its proximal end, and the mounting portion 130 is located in the groove 240. The inner wall of the groove 240 has a second mounting groove 250, which corresponds to the first mounting groove 132. The second mounting groove 250 and the first mounting groove 132 form a sliding cavity. A sliding body 300 is slidably disposed in a sliding cavity along the axial direction. The sliding body 300 is provided with a first connecting hole 310. The adapter 200 is provided with a connecting channel 230. The first connecting hole 310 is used to realize the communication between the connecting channel 230 and the insertion part 400. The sliding body 300 is connected to the operating member 120 through the linkage component 160. The operating member 120 is used to control the sliding body 300 to slide axially along the through hole 131 in the sliding cavity, so as to adjust the communication opening between the first connecting hole 310 and the connecting channel 230.

[0019] Based on the above structural design, during the assembly and production of the endoscope, the insertion part 400 and the adapter 200 can be fixed first, and the slider 300 can be placed into the first mounting groove 132. The proximal end of the insertion part 400 passes into the through hole 131 of the handle, so that the second mounting groove 250 in the adapter 200 corresponds to the slider 300. The slider 300 pre-positions the connection between the adapter 200 and the housing 100, and ensures that the slider 300 and the connecting channel 230 are in the same radial direction. A second connecting hole 410 corresponding to the connecting channel 230 is opened on the insertion part 400. During the fixed connection of the adapter 200 and the handle, the second connecting hole 410, the first connecting hole 310 and the connecting channel 230 are in the same radial direction, eliminating the need for alignment and adjustment steps between the second connecting hole 410, the first connecting hole 310 and the connecting channel 230. During application, when intracavitary perfusion is required, the connecting channel 230 is connected to the perfusion fluid source. The connecting channel 230, the first connecting hole 310, the second connecting hole 410, and the instrument channel on the insertion part 400 constitute a fluid channel. When the operator holds the grip part 110, some fingers can be placed on the operating part 120, allowing the operator to control the endoscope axially, circumferentially, and laterally with one hand, and also drive the operating part 120 with their fingers to move the sliding body 300 within the sliding cavity. This allows the connection opening between the first connecting hole 310 and the connecting channel 230 to change during the movement of the sliding body 300, enabling single-handed control of the flow rate of the perfusion fluid source into the body cavity, reducing the need for manual operation. The difficulty lies in the fact that by setting up a sliding body 300, a sliding cavity, a connecting channel 230, and a second connecting hole 410, a fluid channel on / off control structure is formed. This on / off control structure is integrated at the connection between the insertion part 400 and the handle, allowing the on / off control structure to pre-position the connection between the insertion part 400 and the handle. The connection structure between the insertion part 400 and the handle protects the channel control structure. In conjunction with placing the operating part 120 of the on / off control structure close to the grip part 110, it is possible to control the on / off of the fluid channel with one hand, while also reducing the increase or decrease in the size of the endoscope space caused by the channel control structure, reducing the risk of accidental activation of the channel control structure, improving the safety of endoscope use, increasing the convenience of endoscope assembly and production, and reducing production costs.

[0020] In some embodiments, to reduce operational burden, the handle may further include a reset member 180, which is connected to the operating member 120 or the sliding body 300 to ensure that the sliding body 300 remains in a normal state within the sliding cavity, with the opening of the second connecting hole 410, the first connecting hole 310, and the connecting channel 230 in a coaxial state being 100%. The normal state corresponds to any value between 0% and 100% opening. In this embodiment, the normal state preferably corresponds to the 0% opening value, that is, when no external force is applied, the sliding body 300 is in the closed position, the first connecting hole 310 is misaligned with the connecting channel 230, and the fluid channel is disconnected. When the operating member 120 is pressed or moved, the linkage component 160 drives the sliding body 300 to move, so that the first connecting hole 310 gradually aligns with the connecting channel 230, thereby realizing continuous adjustment of the flow rate from zero to maximum. The reset member 180 can be a spring, sheet, or elastic rubber structure. One end of the reset member 180 is connected to the housing 100, and the other end acts on the operating member 120. One end of the reset member 180 is connected to the inner wall of the sliding cavity, and the other end acts on the sliding body 300, ensuring automatic return to its original position after operation. This prevents continuous outflow of irrigation fluid or negative pressure leakage due to forgetting to close the door, further improving the safety and reliability of use. In some embodiments, the second mounting groove 250 extends proximally to the end face of the groove 240 to allow the sliding body 300 to be pre-positioned during assembly, reducing assembly difficulty.

[0021] In some embodiments, to facilitate the transmission of finger driving force to the slider 300 via the operating member 120, allowing the slider 300 to slide axially within the sliding cavity, the operating member 120 may include a free end 121, a fixed end 123, and a rotating part 122. The rotating part 122 is located between the free end 121 and the fixed end 123, and is rotatably connected to the housing 100. The fixed end 123 is located inside the housing 100 and is connected to the linkage assembly 160. The free end 121 is located near the grip portion 110 outside the housing 100, so that the operator can naturally reach and apply force when gripping the handle. By pressing or flicking the free end 121, the operating member 120 swings around the rotating part 122, thereby driving the linkage assembly 160 to push the slider 300 to move axially, achieving precise control of the fluid channel opening. The outer contour of the operating member 120 can be ergonomically optimized to fit the finger contact surface, improving operating comfort and responsiveness.

[0022] In some embodiments, to enable the linkage assembly 160 to transmit the driving force of the operating member 120 to the sliding body 300, the linkage assembly 160 may include a first linkage member 161 and a second linkage member 162. One end of the first linkage member 161 passes through the sliding cavity and is connected to the sliding body 300. The other end of the first linkage member 161 is rotatably connected to one end of the second linkage member 162. The other end of the second linkage member 162 is rotatably connected to the fixed end 123, so as to convert the swing motion of the operating member 120 into the axial linear motion of the sliding body 300. The first linkage member 161 can extend axially along the sliding cavity and is fixedly connected to the sliding body 300 or reliably connected by means of snap-fit, thread, etc. The overall structure of the linkage assembly 160 is compact and arranged inside the housing 100 without increasing the outer contour size of the handle, while avoiding the intrusion of external liquids or contaminants that may affect the transmission performance.

[0023] In some embodiments, to avoid stress concentration between the first linkage 161 and the sliding cavity, a constraint portion 170 can be provided inside the housing 100. The first linkage 161 is axially slidably connected to the constraint portion 170, and the constraint portion 170 disperses the stress on the first linkage 161, thereby improving the motion stability and service life of the linkage assembly 160. The constraint portion 170 can be a guide groove or guide post provided on the inner wall of the housing 100, and its extension direction is consistent with the axial direction of the sliding cavity, ensuring that the first linkage 161 slides only in a predetermined direction during the transmission of driving force, preventing deflection or jamming. In addition, the constraint portion can also limit the first linkage 161, preventing it from deviating from the preset motion trajectory during operation, further ensuring the accuracy and repeatability of fluid channel opening adjustment.

[0024] Specifically, the first mounting groove 132 is connected to the through hole 131 so that the first connecting hole 310 on the sliding body 300 is connected to the instrument channel inside the insertion part 400 through the second connecting hole 410 on the insertion part 400. During the assembly process, the insertion part 400 and the adapter 200 can be fixed first, and then the second connecting hole 410 can be machined on the insertion part 400. This eliminates the need for alignment and adjustment steps between the first connecting hole 310, the second connecting hole 410 and the connecting channel 230, simplifies the assembly process, and reduces assembly difficulty and production costs.

[0025] In some embodiments, to reduce assembly resistance, the inner diameter of the through hole 131 can be set to be no less than the outer diameter of the insertion part 400, so as to ensure that the insertion part 400 can smoothly penetrate into the housing 100 and avoid assembly difficulties or damage to the surface of the component due to dimensional interference. At the same time, a guide bevel or chamfer structure can be provided at the distal end of the through hole 131 to further guide the insertion part 400 to be accurately aligned, thereby improving assembly efficiency and consistency.

[0026] In some embodiments, a negative pressure interface 140 may be provided on the housing 100. The negative pressure interface 140 is used to connect the insertion part 400 with a negative pressure source so as to connect the negative pressure source and the instrument channel inside the insertion part 400 for suction operation.

[0027] In some embodiments, an instrument interface 150 may be provided on the housing 100. The instrument interface 150 is used to insert surgical instruments into the insertion part 400. The instrument interface 150 is independently provided from the negative pressure interface 140 and the irrigation interface, allowing surgical instruments to enter the body cavity through the instrument channel during negative pressure aspiration and irrigation, thereby improving the flexibility and convenience of endoscopy. The instrument interface 150 is existing technology, and it is preferable to use an instrument interface 150 with a sealing function or a sealing plug.

[0028] In some embodiments, an endoscope includes an insertion part 400 and a handle as described in any of the above embodiments. The proximal end of the insertion part 400 passes through a through hole 131. A second connecting hole 410 is provided on the peripheral wall of the insertion part 400. The second connecting hole 410 corresponds to a connecting channel 230. The first connecting hole 310 is used to enable communication between the connecting channel 230 and the second connecting hole 410. By setting up a slider 300, a sliding cavity, a connecting channel 230, and a second connecting hole 410, a fluid channel on / off control structure is formed. The on / off control structure is integrated at the connection between the insertion part 400 and the handle, allowing the on / off control structure to pre-position the connection between the insertion part 400 and the handle. The connection structure between the insertion part 400 and the handle protects the channel control structure. With the operating part 120 of the on / off control structure positioned close to the grip part 110, it is possible to control the on / off of the fluid channel with one hand, reduce the increase or decrease in the size of the endoscope space caused by the channel control structure, reduce the risk of accidental activation of the channel control structure, improve the safety of endoscope use, increase the convenience of endoscope assembly and production, and reduce production costs.

[0029] In some embodiments, to improve product manufacturing quality, such as Figure 11As shown, an attachment layer 430 can be provided on the insertion part 400. The attachment layer 430 is located within the first mounting groove 132, and the second connecting hole 410 penetrates the attachment layer 430. During assembly, the adapter 200 can be fixedly connected to the insertion part 400 first, and then the proximal end of the insertion part 400 can be inserted into the through hole 131. The attachment layer 430 is then installed at the corresponding position of the insertion part 400 and the first mounting groove 132. Specifically, the attachment layer 430 can be glued to the insertion part 400, or it can be heat-fused to the insertion part 400. The attachment layer 430 enhances the strength of the corresponding part of the insertion part 400 in the first mounting groove 132. Then, a second connecting hole 410 is formed in the insertion part 400, penetrating the attachment layer 430 and the insertion part 400. The second connecting hole 410 is protected by the attachment layer 430 during this process, reducing the risk of damage to the insertion part during the opening of the second connecting hole 410. Simultaneously, it improves the structural strength of the second connecting hole 410, enabling it to stably resist fluid flow and sliding wear of the slider 300 during application, thus preventing damage and deformation. This enhances the connection sealing and structural stability between the second connecting hole 410 and the slider 300, avoiding problems with fluid channel connectivity and sealing caused by structural changes at the second connecting hole 410, and effectively improving the safety and stability of the equipment. In other embodiments, the attachment layer 430 can be fixed to the insertion part 400 first, then the second connecting hole 410 can be opened, and then the adapter 200 can be fixed to the insertion part 400. Subsequently, the insertion part 400 and the handle are fixedly connected.

[0030] In some embodiments, to improve the sealing performance between the second connecting hole 410 on the insertion part 400 and the first connecting hole 310 on the sliding body 300 during the sliding process of the sliding body 300, and to reduce the risk of fluid leakage, a first annular groove can be provided on the side of the attachment layer 430 near the sliding body 300. The first annular groove is used to install a first flexible sealing ring 420. The first annular groove surrounds the second connecting hole 410. The first flexible sealing ring 420 remains in contact with the outer wall of the sliding body 300 during the movement of the sliding body 300, forming a dynamic sealing interface, effectively preventing fluid leakage from the mating area between the second connecting hole 410 and the first connecting hole 310. Preferably, the first flexible sealing ring 420 can be made of a material with corrosion resistance, wear resistance and good elasticity, such as silicone or fluororubber, to adapt to the use environment of different fluid media and ensure stable sealing performance during repeated opening and closing operations. In addition, the cross-sectional shape of the first annular groove can be designed as rectangular, trapezoidal or dovetail to enhance the positioning stability of the first flexible sealing ring 420 and prevent it from shifting or falling off under high pressure or high frequency operation, thereby further ensuring the sealing reliability of the fluid channel.

[0031] In some embodiments, to improve the sealing performance between the first connecting hole 310 and the connecting channel 230 on the sliding body 300 during sliding, a second annular groove 251 can be provided on the inner wall of the second mounting groove 250. The second annular groove 251 is used to install a second flexible sealing ring 260. The second annular groove 251 surrounds the port of the connecting channel 230. The second flexible sealing ring 260 remains in contact with the outer wall of the sliding body 300 during the movement of the sliding body 300, forming another dynamic sealing interface, effectively preventing fluid leakage from the docking area between the first connecting hole 310 and the connecting channel 230. Preferably, the second flexible sealing ring 260 can also be made of a corrosion-resistant, wear-resistant, and elastic material, such as silicone or fluororubber, to adapt to the working conditions of various media such as injection fluid, pharmaceuticals, or gases, and to ensure a stable sealing effect during long-term repeated adjustment of the opening. In addition, the cross-sectional shape of the second annular groove 251 can also be designed as a rectangular, trapezoidal or dovetail structure to enhance the installation firmness of the second flexible sealing ring 260 and prevent it from shifting, flipping or falling off under high pressure differential or frequent operation, thereby further improving the sealing integrity and operational reliability of the fluid passage during the adjustment process.

[0032] In some embodiments, a lever structure may be provided on the handle, which controls the directional bending of the distal end of the insertion part 400. The lever structure is prior art. Exemplarily, the lever structure includes a lever, a traction wheel, and a traction rope. The distal end of the traction rope is connected to the distal end of the insertion part, and the proximal end of the traction rope is connected to the traction wheel. The lever is connected to the traction wheel. By manipulating the lever, the traction wheel is rotated, pulling the traction rope on one side of the insertion part 400 towards the proximal end, while simultaneously releasing the traction rope on the other side of the insertion part 400 towards the distal end. The insertion part 400 is bent at both ends. The traction rope moves in the opposite direction, thereby causing the distal end of the insertion part 400 to bend in a specific direction. In other examples, a single traction rope can control the unilateral directional bending of the insertion part 400. Multiple traction ropes can also be used to achieve four-way bending of the insertion part 400. The above examples of lever structures that realize the directional bending function of the insertion part 400 can all directly adopt existing designs. An illumination unit and a camera module are provided on the distal end surface of the insertion part 400. The illumination unit is used to provide illumination light, and the camera module is used to acquire image information of the interior of the distal cavity of the insertion part.

[0033] In some embodiments, the axial length of the attachment layer 430 may be set to match the first mounting groove 132.

[0034] The endoscope provided in this application embodiment can be a suction endoscope, or a bronchoscope, nephroscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This application embodiment does not specifically limit the type of endoscope.

[0035] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
