Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a dilator with adjustable smoke suction port. BACKGROUND

[0002] With the popularization and development of minimally invasive surgery technology, surgical dilators have become an indispensable tool in various surgical operations. Modern surgical dilators not only can effectively expand the surgical field and improve the accuracy of surgical operation, but also integrate various auxiliary functions to meet the needs of complex surgical environment. Among them, the smoke suction function is one of the standard configurations of high-end surgical dilators, which can timely exhaust the smoke generated by electric knives, lasers and other surgical instruments through the built-in smoke duct system.

[0003] In the existing technical solutions, surgical dilators usually adopt fixed smoke suction port design, and the smoke duct penetrates through the dilator main body and is connected with the external negative pressure suction system. This design can meet the basic needs in the conventional surgical scene, but when the smoke volume suddenly increases, such as using high-frequency electric knives for large-area tissue cutting, the fixed size and position of the smoke suction port cannot timely cope with the sudden increase in smoke volume. In addition, due to the space limitation of the surgical area, the dilator often needs to maintain a specific angle and position, which further limits the capture efficiency of the smoke suction port to the dynamically changing smoke.

[0004] Research has found that when the smoke volume exceeds the system processing capacity, the smoke that is not timely exhausted will accumulate in the surgical area, not only affecting the clarity of the surgical field, but also potentially harming the respiratory system of medical staff.

[0032] As Figure 1As shown, the present application provides a smoke suction adjustable dilator, which comprises a shell 1 and a smoke cover assembly; the shell 1 is formed with smoke inlets 1014, the smoke inlets 1014 are multiple, the smoke cover assembly comprises multiple cover bodies 5, the multiple cover bodies 5 are arranged corresponding to the smoke inlets 1014, and one end of the cover body 5 is rotationally connected with the shell 1, and the other end can open or close the smoke inlets 1014; a flue is formed in the shell 1, and a smoke outlet nozzle 1012 is integrated at the tail of the shell 1, and the flue is respectively connected with the smoke inlets 1014 and the smoke outlet nozzle 1012.

[0033] Compared with the prior art, the smoke suction adjustable dilator provided by the present application has the following advantages: The smoke suction adjustable dilator provided by the present application, the shell 1 as a whole support structure, provides a mounting base for the smoke cover assembly and other components. The shell 1 is formed with a flue inside for guiding the flow of smoke. Connection, the shell 1 is integrated with multiple smoke inlets 1014 and a smoke outlet nozzle 1012, one end of the flue is connected with all the smoke inlets 1014, and the other end is connected with the smoke outlet nozzle 1012, so that the suction and discharge of smoke can be realized.

[0034] And in the present application, the cover body 5 is rotationally connected with the shell 1, which can realize the opening and closing and opening degree adjustment of the smoke inlets 1014. When the smoke concentration changes during the operation, the user can rotate the cover body 5 to adjust the size of the smoke inlets 1014, for example, when the smoke amount increases greatly, the cover body 5 is rotated to the maximum opening angle to increase the smoke suction area, and when the smoke is low, the cover body 5 is partially closed, so that the opening degree of the smoke inlets 1014 is smaller, so that the air flow can be optimized. When there is no smoke, the cover body 5 can be completely closed, so that dust or liquid splashed in the operation can be avoided in the shell 1, the cleanliness in the shell 1 is improved, and the service life of the whole dilator is increased.

[0035] It can be understood that, by rotationally connecting the cover body 5 with the shell 1 and dynamically adapting the smoke inlets 1014 to the smoke concentration, the smoke suction efficiency can be improved to a certain extent, the operation environment is kept clean, and the limitation of fixed smoke inlets is overcome.

[0036] Optionally, as shown in the drawings, Figure 1 Combined with the drawings, Figure 4 As shown, the smoke suction adjustable dilator provided by the present application further comprises a suction assembly, the suction assembly comprises a gas pump 2 and a gas pipe 3, the gas pump 2 is arranged in the shell 1, and the gas inlet end of the gas pump 2 is connected with one end of the gas pipe 3, and the other end of the gas pipe 3 is connected with the smoke inlets 1014.

[0037] The suction assembly provided by the application is composed of an air pump 2 and an air pipe 3. The air pump 2 can actively suck smoke, thereby enhancing the suction capacity. The air pump 2 is arranged in the shell 1. The air inlet end of the air pump 2 is connected to one end of the air pipe 3, and the other end of the air pipe 3 leads to the smoke inlet 1014 area, thereby forming a negative pressure suction force in the smoke inlet 1014 area. When smoke needs to be absorbed, the air pump 2 is started, and smoke is actively extracted through the air pipe 3, thereby increasing the smoking speed to a certain extent and effectively dealing with high smoke volume. It can be understood that when the smoke volume increases sharply, the negative pressure formed by the air pump 2 is used to open the cover 5 to the maximum angle, thereby enabling the smoke to quickly enter the shell 1, guiding the smoke to the smoke outlet 1012 through the air pipe 3, and finally discharging into the recycling area.

[0038] Optionally, as Figure 1 combined Figure 4 shown, the shell 1 in the application includes an upper cover 101 and a bottom shell. The smoke inlet 1014 is formed in the upper cover 101. The inner part of the upper cover 101 is formed with a baffle 1015. When the upper cover 101 is connected with the bottom shell, the baffle 1015 divides the shell 1 into a smoke guide cavity and a containing cavity. The air pump 2 is arranged in the containing cavity. The end of the air pipe 3 away from the air pump 2 is connected with the smoke guide cavity.

[0039] The upper cover 101 and the bottom shell in the application are detachably connected. When internal devices need to be repaired or replaced, the upper cover 101 can be removed to quickly maintain and update the internal structure. The smoke inlet 1014 and the light outlet 1013 described below can also be integrated through the upper cover 101. The bottom shell can provide structural support for the overall dilator.

[0040] In connection, the two are combined by buckling. The application further provides the baffle 1015 arranged on the inner side of the upper cover 101, which can divide the inside of the shell 1, thereby forming the containing cavity and the smoke guide cavity. The containing cavity is used for installing the air pump 2 and the control member 11 and other structures. When the upper cover 101 is installed with the bottom shell, the position corresponding to the smoke inlet 1014 can form a relatively sealed smoke guide cavity through the baffle. By connecting the air pipe 3 with the smoke guide cavity, the smoke can only flow through the air pipe 3, avoiding the escape of smoke. Correspondingly, when the air pump 2 is started, the air pipe 3 can form a negative pressure in the smoke guide cavity, realizing the suction of smoke.

[0041] Optionally, as Figure 1 combined Figure 4 shown, the suction assembly in the application further includes a filter 4. The filter 4 is arranged outside the shell 1, and the air inlet end of the filter 4 is connected to the smoke outlet 1012.

[0042] By providing a filter element 4 outside the housing 1, and connecting the air inlet end of the filter element 4 to the exhaust nozzle 1012, the harmful fumes discharged from the housing 1 can be filtered and purified. The purified gas can be directly discharged into the air without connecting to the existing smoke return pipeline. This allows the expander provided in this application to be used independently without connecting to other structures, thereby avoiding the problem of pipelines connected to the expander affecting the surgical environment.

[0043] Preferably, such as Figure 3 As shown, the end face of the opening and closing end of the cover 5 in this application includes an arc segment 501 and a straight segment 502. When the straight segment 502 abuts against the inner wall of the smoke inlet 1014, the cover 5 stops rotating.

[0044] The end face of the opening and closing end of the cover 5 includes an arc-shaped segment 501 and a straight segment 502. The inner wall of the smoke inlet 1014 is a flat plane. Therefore, the arc-shaped segment 501 allows for free movement of the opening and closing end of the cover 5. When the cover 5 rotates to the point where the straight segment 502 contacts the inner wall of the smoke inlet 1014, the contact between the two flat planes restricts the rotation of the cover 5, thus stopping the cover 5 and preventing it from being over-opened.

[0045] More preferably, the area of ​​the arc-shaped segment 501 is covered with a filter screen 6, so that when the cover 5 is opened, it can filter dust or other debris to a certain extent and ensure the cleanliness of the inner cavity of the housing 1.

[0046] It should be added here that, such as Figures 1-4 As shown in the figure, in the scheme illustrated in this application, there are three smoke inlets 1014, and correspondingly, there are three hoods 5. Each hood 5 can be controlled individually. That is, in actual operation, one hood 5, two hoods, or all hoods 5 can be opened, thereby making the adjustment of the smoke inlet area more flexible.

[0047] Optionally, such as Figure 2 Combination Figure 3 As shown, in this application, the upper cover 101 has a buckle groove 1011 at the position of the side wall of the cover 5, and the cover 5 has a buckle handle 505 at the position of the buckle groove 1011.

[0048] Since the cover 5 is on the same plane as the outer wall of the top cover 101 when closed, this application forms a buckle groove 1011 on the side wall of the top cover 101 and a handle 505 on the cover 5 corresponding to the buckle groove 1011, which facilitates operation by medical staff. Furthermore, since medical staff always wear gloves during surgery, the outwardly extending handle 505 also facilitates the movement of the cover 5 by medical staff, thus achieving the above-mentioned smoking function.

[0049] In the preferred embodiment of this application, such as Figure 3As shown, the smoking cover assembly in the application further comprises a connecting rod 7, the side of each of the plurality of cover bodies 5 is formed with a connecting lug 503, the connecting lug 503 is formed with a connecting protrusion, the connecting rod 7 is rotationally connected with the connecting protrusion, so as to realize synchronous movement of the plurality of cover bodies 5.

[0050] Through the connecting rod 7, the three cover bodies 5 can be connected in series, so that when one cover body 5 rotates, the connecting rod 7 can realize synchronous movement of the three cover bodies 5, i.e. synchronous opening and synchronous closing, thereby greatly improving the operation efficiency and reducing the operation difficulty.

[0051] Optionally, as shown, Figures 1-4 As shown, the smoking port adjustable dilator provided by the application further comprises an illumination assembly, the upper cover 101 is formed with a light outlet 1013, the illumination assembly comprises a lamp strip 8, a lamp bead, an electric wire 9, a power supply 10 and a control member 11; the light outlet 1013 is located between adjacent smoke inlets 1014, the lamp bead is arranged corresponding to the light outlet 1013, and the lamp bead is integrated on the lamp strip 8, the tail of the lamp strip 8 is connected with the electric wire 9, the electric wire 9 passes through the baffle 1015 and is connected with the control member 11, and the power supply 10 is integrated on the control member 11.

[0052] Since the lamp strip 8 is arranged in the smoke guide cavity, the application further forms a through hole in the baffle 1015, so as to realize the passing of the electric wire 9 and ensure the sealing of the smoke guide cavity, and correspondingly, the lamp strip 8 and the control member 11 can be connected through the electric wire 9, and the power supply 10 in the application is integrated on the control member 11, so that the power supply 10 can provide power supply for the whole lamp strip 8 and the lamp bead, and can also provide power supply for the above-mentioned air pump 2, so as to realize the power demand inside the whole dilator. The air pump 2 is also connected with the control member 11 through a wire, so that the opening and closing of the illumination assembly and the opening and closing of the air pump 2 can be realized by integrating a button outside the shell 1.

[0053] It should be noted here that the lamp bead in the application corresponds to the light outlet 1013 formed by the upper cover 101, and the light outlet 1013 is covered with a light transmission plate, so as to ensure the sealing degree and cleanliness in the smoke guide cavity.

[0054] Optionally, as shown, Figure 4 In combination with Figure 5As shown, the smoking port adjustable dilator provided by the present application further comprises a first adjusting assembly. The side of the cover body 5 facing the lamp strip 8 is formed with a linkage block 504, the lamp strip 8 is formed with a avoiding hole corresponding to the position of the linkage block 504, and the linkage block 504 is arranged through the avoiding hole. The first adjusting assembly comprises a first positioning block 12, a first elastic member 15, a first mounting block 14, a first rotating wheel 13, a first rotating shaft and a first knob. The first knob is connected with one end of the first rotating shaft, the other end of the first rotating shaft is rotatably connected with the first mounting block 14 extending into the shell 1, and the first rotating wheel 13 is mounted on the first rotating shaft. The first positioning block 12 is fixed on the bottom shell, and the first elastic member 15 is located between the first positioning block 12 and the first mounting block 14, so that the first mounting block 14 can move towards or away from the first positioning block 12. The outer wall of the first rotating wheel 13 and the outer wall of the linkage block 504 are both formed with engagement portions 5041, so that the first rotating wheel 13 and the linkage block 504 are engaged.

[0055] Based on the above structure, the present application further provides an embodiment of opening and closing the cover body 5. Specifically, in the embodiment, the first positioning block 12 is mounted on the bottom shell, thereby providing a basis for the installation of the first elastic member 15 and the first mounting block 14. It can be understood that the first mounting block 14 and the first positioning block 12 are arranged in the vertical direction, i.e. the thickness direction of the dilator, and the first mounting block 14 and the first positioning block 12 are movably connected. That is, when the first elastic member 15 is not arranged, the first mounting block 14 falls on the first positioning block 12 due to its own gravity. By arranging the first elastic member 15, the first mounting block 14 and the first positioning block 12 can be arranged at intervals, and the movement of the first mounting block 14 relative to the first positioning block 12 can be realized.

[0056] Since the outer wall surface of the first rotating wheel 13 and the outer wall surface of the linkage block 504 are both formed with engagement portions 5041 in the present embodiment, the first rotating wheel 13 and the linkage block 504 are engaged with each other. When the first rotating wheel 13 rotates, it can drive the linkage block 504 to rotate, thereby realizing the rotation of the cover body 5, and further realizing the opening and closing of the cover body 5 relative to the upper cover 101.

[0057] Therefore, by further arranging the first rotating shaft connected with the first rotating shaft and the first knob arranged outside the shell 1, the operation of the cover body 5 can be realized. That is, in actual operation, the operator can drive the first rotating shaft to rotate by rotating the knob, thereby driving the first rotating wheel 13 arranged on the first rotating shaft to rotate, and further realizing the rotation of the linkage block 504 through the engagement relationship, so that the cover body 5 rotates and realizes the opening and closing action of the cover body 5.

[0058] It can be understood that, as Figure 5As shown, since the linkage block 504 is an extension of the tail of the cover 5, when the cover 5 rotates along its own rotation axis, the trajectory of the end of the linkage block 504 is arc-shaped. Therefore, when the end of the linkage block 504 is closer to the bottom shell during movement, the first elastic member 15 can be compressed, thereby ensuring the movement of the overall structure.

[0059] Preferably, a damping ring is further arranged on the first rotating shaft in the application. The damping ring can stop the rotating wheel at the required adjustment position, thereby ensuring the stability of the opening degree of the cover 5 to a certain extent.

[0060] It should be noted that in the present mode, when the cover 5 is closed, the end of the linkage block 504 close to the side surface is in abutment with the first rotating wheel 13. At this position, the first elastic member 15 drives the first rotating wheel 13 to generate an upward thrust, thereby making the cover 5 more stable in the closed state, and thereby avoiding the problem that the opening of the cover 5 during the operation process due to misoperation affects the operation process to a certain extent, and protecting the patient from being injured by the accidental opening of the cover 5.

[0061] It should be further noted that since the cover 5 provided in the application is three, in actual application, the first adjusting assembly can correspond to the cover 5 one by one, and of course, can be combined with the connecting rod 7 described above, thereby realizing the synchronous adjustment of the three covers 5 through one first knob. The above two modes have advantages and can be reasonably combined according to specific needs, and the operation logic is the same, which will not be described here.

[0062] Optionally, as Figure 4 In combination Figure 6 As shown, the smoke-adjustable dilator provided in the application further comprises a second adjusting assembly, the cover 5 is formed with a linkage block 504, and the linkage block 504 passes through the avoiding hole; the second adjusting assembly comprises a second positioning block 16, a second elastic member 19, a second mounting block 18, a second rotating wheel 17, a second rotating shaft, and a second knob; the second knob is connected with one end of the second rotating shaft, the other end of the second rotating shaft is rotatably connected with the second mounting block 18 which extends into the shell 1, the second rotating wheel 17 is installed on the second rotating shaft; the second positioning block 16 is fixed on the inner wall of the upper cover 101, and the second positioning block 16 and the second mounting block 18 are arranged in the length direction of the upper cover 101; the second elastic member 19 is located between the second positioning block 16 and the second mounting block 18, so that the second mounting block 18 can move towards or away from the second positioning block 16; the outer wall of the second rotating wheel 17 and the outer wall of the linkage block 504 are both formed with engaging portions 5041, so that the second rotating wheel 17 is engaged with the linkage block 504.

[0063] The second cover 5 opening and closing embodiment is further provided in the application, in which the second positioning block 16 is installed on the inner wall of the upper cover 101, thereby providing a basis for the installation of the second elastic member 19 and the second mounting block 18. It can be understood that the second mounting block 18 and the second positioning block 16 are arranged in the horizontal direction, i.e., the length direction of the dilator, and the second mounting block 18 is movably connected with the second positioning block 16. By arranging the second elastic member 19, the second mounting block 18 and the second positioning block 16 can be spaced apart, and the movement of the second mounting block 18 relative to the second positioning block 16 can be realized.

[0064] In the present embodiment, the outer wall surface of the second rotating wheel 17 and the outer wall surface of the linkage block 504 are both formed with the engaging portion 5041, so that the second rotating wheel 17 and the linkage block 504 are engaged with each other. When the second rotating wheel 17 rotates, the linkage block 504 can be driven to rotate, thereby realizing the rotation of the cover 5, and further realizing the opening and closing of the cover 5 relative to the upper cover 101.

[0065] Therefore, by further arranging the second rotating shaft and the second knob connected with the second rotating shaft and arranged outside the shell 1, the operation of the cover 5 can be realized. In actual operation, the operator can drive the second rotating shaft to rotate by rotating the second knob, thereby driving the second rotating wheel 17 arranged on the second rotating shaft to rotate, and further realizing the rotation of the linkage block 504 through the engagement relationship, so that the cover 5 rotates and the opening and closing action of the cover 5 is realized.

[0066] It can be understood that, as shown in Figure 6 Since the linkage block 504 is an extension of the tail portion of the cover 5, when the cover 5 rotates along the rotating shaft thereof, the movement track of the end portion of the linkage block 504 is arc-shaped. Therefore, when the end portion of the linkage block 504 is closer to the upper cover 101 during movement, the second elastic member 19 can be compressed by the second mounting block 18 and the second elastic member 19 arranged in the application, thereby ensuring the movement of the overall structure.

[0067] Preferably, the second rotating shaft is further provided with a damping ring in the application. The rotating wheel can be stopped at the required adjustment position by arranging the damping ring, thereby ensuring the stability of the opening degree of the cover 5 to a certain extent.

[0068] It should be noted that, in the present embodiment, as shown in Figure 6 When the cover 5 is opened to the maximum position, the end portion of the linkage block 504 close to the side surface will be abutted with the second rotating wheel 17, and at this state, the second elastic member 19 will drive the second rotating wheel 17 to generate a forward thrust, thereby making the cover 5 more stable in the opened state, and further avoiding the problem that the closure of the cover 5 during the operation process due to misoperation affects the operation process to a certain extent.

[0069] It needs to be further supplemented here that since the cover body 5 provided by the present application is three, in actual application, the second adjusting assembly can correspond to the cover body 5 one by one, and of course, can be combined with the connecting rod 7 described above, so as to realize the synchronous adjustment of the three cover bodies 5 through one second knob. The above two ways have advantages respectively, and can be reasonably combined according to specific needs, and the operation logic is the same, which will not be repeated here.

[0070] Preferably, in order to ensure the stability of the cover body 5 in the closed state, a locking groove 1016 is further formed on the upper cover 101, and the arc-shaped section 501 of the cover body 5 is provided with a locking member 20, and the locking member 20 in the present application can be a ball plunger, when the cover body 5 is opened, the ball head of the ball plunger protrudes, and when the cover body 5 is closed, the ball head is pressed back, and when encountering the locking groove 1016, it protrudes again, thereby completing the locking of the cover body 5.

[0071] The further provided locking member 20 can further ensure the closure stability of the cover body 5 and ensure the safety of the operation.

[0072] The above only describes the preferred embodiments of the present application and does not limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
