Description

A multifunctional maxillary sinus mirror TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a multifunctional maxillary sinus mirror. BACKGROUND

[0002] When teeth in the posterior maxillary region are lost and need to be implanted, if the bone height in this region is insufficient to place an implant, maxillary sinus lifting surgery is needed to separate the maxillary sinus mucosa from the sinus floor bone wall and implant bone in the space separated, that is, to lift the maxillary sinus floor bone height. After obtaining sufficient bone height, the subsequent implant implantation can be completed. However, the maxillary sinus lifting surgery is generally operated under blind vision, and the maxillary sinus mucosa perforation is easy to occur. After the perforation, the maxillary sinus surgery failure is easy to occur, and the maxillary sinus infection and even the implant bone healing are easy to be affected, which increases the risk of implant surgery failure. In order to reduce the probability of maxillary sinus mucosa perforation, after the 1990s, the endoscope-assisted maxillary sinus lifting surgery was proposed and applied.

[0003] Through the analysis of the current endoscope-assisted maxillary sinus lifting surgery method, it is found that these methods have the following main shortcomings: 1. There is no observation and operation integrated multifunctional mirror specially designed for maxillary sinus lifting surgery. 2. The current endoscope-assisted maxillary sinus lifting surgery approach is nasal cavity, which will cause additional surgical path trauma to the implant patient during the operation; 3. The current endoscope-assisted maxillary sinus lifting surgery cannot simultaneously enter the operation area with the endoscope and the lifting instrument, and cannot observe and operate synchronously; some are operated by two people, which needs more manpower and cannot be completed by a single person.

[0004] SUMMARY

[0005] The core problems existing in the current original instrument include: 1. The observation and operation of the current original instrument are completed by two different instruments, and the observation and operation cannot be performed synchronously; 2. The approach of the current original instrument is nasal cavity, and some are upper maxillary sinus lateral wall or alveolar ridge top approach, and a set of instruments cannot be used for multiple approach operations; 3. The current original ear-nose-throat nasal endoscope is often used for maxillary sinus lifting surgery, which does not have the functions of lateral observation, flushing, air injection and negative pressure suction; 4. The current original instrument cannot achieve large-range maxillary sinus mucosa stripping; 5. The current original instrument cannot strip the mucosa in the complex structure area (such as the maxillary sinus septum or the maxillary sinus medial wall); 6. The current observation and operation tools are large, and a set of observation and operation tools can still complete the implant implantation after the maxillary sinus lifting through the lifting operation hole.

[0006] To solve one or more of the above problems, the present application describes a multifunctional maxillary mirror, which integrates the operation function, video acquisition function, liquid spraying function, air spraying function, and negative pressure suction function into a thin tube body that can pass through the prepared bone hole, so as to achieve safer and more effective surgical treatment.

[0007] Specifically, the present application describes a multifunctional maxillary mirror, which includes a main tube body, the main tube body including a main tube body body part and a main tube body top operation end,

[0008] The main tube body top operation end is used to pass through the prepared bone hole in the maxilla of a human or animal body to enter the operation area for operation; and the diameter of the main tube body top operation end is less than 6 mm.

[0009] The main tube body top operation end includes:

[0010] A video acquisition module is used to observe the surgical field area during surgery.

[0011] A data cable channel is used to set a data cable for data transmission.

[0012] An operation channel is used to guide the operation assembly into the operation area for operation.

[0013] A liquid spraying channel is used to spray water for flushing the operation area.

[0014] An air spraying channel is used to spray air for the operation area.

[0015] A negative pressure channel is used to extract blood generated during operation and liquid generated during flushing in the operation area by negative pressure.

[0016] The paths of the data cable channel, the liquid spraying channel, the air spraying channel, the negative pressure channel, and the operation channel in the main tube body body part and the main tube body top operation end are continuous.

[0017] By setting the data cable channel, the liquid spraying channel, the air spraying channel, the negative pressure channel, and the operation channel in the main tube body top operation end, the video acquisition function, the water flushing function, the air spraying function, the negative pressure suction function, and the operation function are integrated into the main tube body top operation end with a diameter of less than 6 mm, so that safe operation on the operation area can be completed under the condition of video acquisition.

[0018] Further, the negative pressure channel and the operation channel are integrated into one channel, which is defined as a negative pressure operation channel.

[0019] The cross-sectional area of the negative pressure operation channel accounts for 50% or more of the cross-sectional area of the main tube body body part.

[0020] The diameter of the main tube body top operation end is not less than the diameter of the main tube body body part.

[0021] The main pipe body is provided with an operation inlet on the body part, which is used for the operation tool to enter; the operation inlet is communicated with the negative pressure operation channel; the pressure in the negative pressure operation channel is adjusted by adjusting the size of the operation inlet;

[0022] The first end of the top operation end of the main pipe body is the first end which enters the surgical area first; the other end opposite to the first end is the second end; the first end of the top operation end of the main pipe body is the total outlet end; the total outlet end includes the data cable channel, the liquid spraying channel, the air spraying channel and the outlet of the negative pressure operation channel.

[0023] Further, the operation on the side tissue is completed by setting the total outlet on the side of the main pipe body; for example, the negative pressure operation outlet is taken as an example for illustration, and the specific scheme is as follows: the operation assembly is used for stretching into the surgical area in the side direction of the main pipe body body part under the guidance of the negative pressure operation channel and the negative pressure operation outlet and the image guidance of the video acquisition module (2) to perform the operation.

[0024] Further, the video acquisition module is used to enter the surgical area first to ensure that the surgical area is observed first before subsequent operations are performed, so as to avoid mucosa damage caused by improper entry; the specific scheme is as follows: the video acquisition module includes a camera and a signal line; the camera and the negative pressure operation outlet are both arranged at the first end of the main pipe body body part; when entering the surgical area along the operation path, the video acquisition opening enters the surgical area first; in addition, the camera is embedded in the top operation end of the main pipe body body part and is connected with the rear-end power supply and the video display device through the lead wire and the transmission line.

[0025] Further, the mirror front operation section is arranged perpendicularly to the main pipe body body part to ensure the realization of the side opening.

[0026] Further, the length of the main pipe body body part is limited to ensure that the main pipe body body part has sufficient penetration strength under a relatively small pipe diameter; and in order to meet the needs of short-path small-operation-inlet-diameter surgery, the specific technical scheme is as follows: the length of the main pipe body body part ranges from 0.4 cm to 20 cm; further, the length ranges from 0.4 cm to 10 cm; the main pipe body body part is arranged as a hard pipe body, such as a hard plastic pipe body or a metal pipe body, to further ensure the strength of the pipe body when penetrating the operation path and entering the surgical area.

[0027] Further, the hand-held sleeve is arranged at the second end of the main pipe body body part to facilitate the operation of the main pipe body body part; the specific technical scheme is as follows: the maxillary sinus mirror includes a hand-held sleeve which is used for holding to complete the operation; further, the main pipe body body part is communicated with the channels in the hand-held sleeve in a corresponding manner; further, the main pipe body body part is connected with the hand-held sleeve in an angle manner; further, the size of the hand-held sleeve is larger than that of the main pipe body body part, and the hand-held sleeve is provided with channels consistent with the main pipe body body part.

[0028] Further, the above maxillary sinus mirror is generated according to the problems of the maxillary sinus, but its application is not limited to performing maxillary sinus related surgery, and specifically can also be: maxillary sinus stripping, maxillary sinus foreign body clipping, root tip surgery, root canal broken needle, puncture sampling, dislocation broken root clipping; temporomandibular joint mirror examination; root canal side puncture diagnosis and treatment; treatment of jaw cysts; observation operation mirror for pathological biopsy, external ear canal cleaning surgery, etc.

[0029] Further, the control box is arranged to realize the various function operations and implementations in the channel of the main pipe body, and the specific scheme is that the main pipe body is connected with the control box through the connecting pipe, and the control of the flushing action and the video acquisition module is completed by one control box; the control box is further connected with the flushing instrument and the video acquisition end. Finally, an effective system for observing and operating the maxillary sinus is formed.

[0030] The advantages of the present application are as follows:

[0031] 1. Through the ingenious structure, the video acquisition module is arranged in the middle of the upper half circle of the main pipe body (viewed from the cross-sectional angle), the liquid spraying channel and the air spraying channel are arranged on both sides of the main pipe body, and then the negative pressure channel is arranged in the lower half circle, and the operation channel is preferably integrated in the negative pressure channel, so that the space is compressed to the maximum, and multiple functions such as operation, observation, flushing and air spraying can be realized by one instrument, the problem that one person cannot simultaneously complete observation and operation is solved, and flushing, air spraying and negative pressure suction in the maxillary sinus surgery can be completed without changing the instrument. In addition, through a thin main pipe body, the present application can be applied to various surgeries of the maxillary sinus, and is especially suitable for the surgical method through the alveolar ridge top approach.

[0032] 2. By arranging the total outlet on the side of the main pipe body, the negative pressure operation outlet on the total outlet is also arranged on the side of the main pipe body, so that the operation on the lateral surgical area can be effectively completed, and the maxillary sinus mucosa stripping operation can be realized, and the maxillary sinus mucosa stripping operation can be realized.

[0033] 3. By arranging the main pipe body and the hand-held sleeve connected at an angle, and by arranging the hand-held sleeve to be larger than the main pipe body, the operation convenience of the entire maxillary sinus mirror can be increased under the premise that the main pipe body is thin.

[0034] 4、By setting the video acquisition module, various operations can be completed under visualization, so that the operation tool is highly integrated with the endoscope function, greatly reducing the blindness of the operation, the camera is embedded in the top operating end of the main pipe body, the image clarity is higher than that of the endoscope equipment using optical fiber transmission image in the current clinic, and the camera can take pictures and record videos during the operation, and the real-time transmission can be viewed on the video display device, in addition to the operator, the operation and key steps can also be clearly seen by the observers, which is helpful for medical teaching.

[0035] 5、The maxillary sinus mirror of the present application can be applied to various actual operation conditions, the operation assembly can be randomly replaced according to actual needs, and different length and diameter stripping assemblies can be selected according to needs, in addition to meeting the needs of the oral cavity, the maxillary sinus mirror can also be used to enter the nasal cavity through the oral cavity to perform nasal cavity related operations, and can also be applied to any application scene with short and thin operation path, and the operation tool can be selected according to needs, so that the problem of limited and single function is eliminated.

Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the present application. The present application can also be implemented or applied by other different specific embodiments. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0064] Referring to FIGS. 1-8, a maxillary sinus mirror comprises a main pipe body 1, which comprises a main pipe body body part 161 and a main pipe body top operation end 15,

[0065] The main pipe body top operation end 15 is arranged at the top of the main pipe body body part 161 and is used for entering the operation area through the prepared bone hole in the maxilla of a human or animal body; the diameter of the main pipe body top operation end 15 is less than 6 mm; more preferably, less than 4 mm.

[0066] The main pipe body top operation end 15 comprises:

[0067] Video acquisition module 2, video acquisition module 2 includes a camera and a signal line; for observing the surgical field area during surgery;

[0068] Data cable channel 12;

[0069] Operation channel, for guiding the operation assembly into the operation area for operation;

[0070] Liquid spray channel 13, for water flushing of the operation area;

[0071] Air spray channel 14, for air spraying of the operation area; air spraying is used to fill the operation area;

[0072] Negative pressure channel, for negative pressure extraction of blood generated during operation of the operation area and liquid generated during flushing;

[0073] Data cable channel 12, liquid spray channel 13, air spray channel 14, negative pressure channel, operation channel in the path of other parts of the main body body part 161 and the main body top operation end 15 continue;

[0074] By setting data cable channel 12, liquid spray channel 13, air spray channel 14, negative pressure channel, operation channel 11 in the main body top operation end 15, the video acquisition function, water flushing function, air spraying function, negative pressure suction function and operation function are integrated into the main body top operation end 15 with a diameter less than 6mm, which can complete the safe operation of the operation area under the condition of video acquisition.

[0075] More preferably, the main body top operation end 15 has a diameter not less than the diameter of the other parts of the main body body part 161; such size setting can meet the diameter requirement of the main body top operation end 15, and the other parts can be smaller than the main body top operation end 15.

[0076] In the embodiment of the application, the main body top operation end 15 and the main body body part 161 have the same diameter as an example for scheme setting. In specific implementation, the main body body part 161 is a hard straight pipe as a whole.

[0077] When the maxillary sinus mirror is operated and the implant such as implant tooth is implanted at the same time, in order to ensure the initial stability of the implant, the implanted bone hole is required to be smaller than the diameter of the implant; the diameter of the main body body part 161 is slightly smaller than the diameter of the bone hole, and such size setting can ensure the smooth operation of the maxillary sinus mirror. The diameter of the part of the implant extending into the bone is commonly about 3.0-5.5mm; the diameter of the main body body part 161 can be but is not limited to the size between 2.8mm and 5.3mm.

[0078] In a specific implementation, the integration of any two channels achieves the purpose of increasing the workspace of each channel, ensuring the effective operation, wherein more preferably: the negative pressure channel and the operation channel are integrated into one channel, defined as the negative pressure operation channel 11; wherein the negative pressure operation channel 11 occupies half or more of the cross-sectional area of the main pipe body 1; more preferably: the liquid injection channel 13, the air injection channel 14, and the data cable channel 12 occupy half of the cross-sectional area of the main pipe body 1 in the main pipe body portion 161; the negative pressure operation channel 11 occupies half of the cross-sectional area of the main pipe body 1; through the above arrangement, the required workspace for operation can be prioritized, and the space required for negative pressure suction of blood and liquid generated during flushing and viscous liquid can be prioritized. Further, by integrating the liquid injection channel 13 and the air injection channel 14 into the main pipe body portion 161 at the same time as the negative pressure operation channel 11, it can ensure that the negative pressure suction of viscous liquid in the surgical area is completed at the same time as the flushing of the surgical area, thereby ensuring a clear surgical field. Thus, it is suitable for surgical conditions with more blood, exudate, and inflammatory tissue in various surgical areas. Preferably, the cross-section of the main pipe body portion 161 and the main pipe body top operating end 15 is circular or elliptical.

[0079] More preferably: define the end of the main pipe body portion 161 that enters the surgical area first as the top of the main pipe body portion 161, and the other end of the main pipe body portion 161, i.e. the tail of the main pipe body portion 161, as the main pipe body end enlargement portion 164; a main pipe body top operating end 15 is provided at the top of the main pipe body 1, and a total outlet 151 is provided on the operating end, the plane where the total outlet 151 is located is defined as the main outlet plane 152, and the position of the main outlet plane 152 relative to the main pipe body portion 161 is defined as the front of the main pipe body portion 161; the total outlet 151 includes the data cable channel 12, the liquid injection channel 13, the air injection channel 14, and the outlet of the negative pressure operation channel 11; the total outlet 151 is a plane; the data cable channel 12, the liquid injection channel 13, the air injection channel 14, and the negative pressure operation channel 11 have consistent channel paths in the main pipe body portion 161.

[0080] More preferably: the outlet of the negative pressure operation channel 11 on the main pipe body top operating end 15 is the negative pressure operation outlet 112, which is directed in a direction that is not directly opposite the top end of the main pipe body portion 161, i.e. the normal direction of the end face of the main pipe body top operating end 15 forms an angle with the axis of the main pipe body portion 161, preferably 45°-180°, more preferably 90°.

[0081] The operating assembly enters the main pipe body top operating end 15 in a direction that is not directly opposite the top end under the guidance of the negative pressure operation channel 11 and the negative pressure operation outlet 112.

[0082] In use, the main tube body 161 is inserted into the surgical area through the prepared bone hole, and then the operating tool (such as a stripping wire) is guided by the negative pressure operation channel 11 and the negative pressure operation outlet 112 to extend from the top operating end 15 of the main tube body (preferably from the lower half thereof) toward the negative pressure operation outlet 112, and the corresponding operation is completed according to the needs.

[0083] In a more preferred embodiment, the video acquisition module 2 comprises a camera device with an illumination structure 22, which comprises an integrated camera module 21 and an illumination structure 22. The illumination structure 22 is located on one side or both sides of the camera device; the camera device and the negative pressure operation outlet 112 are both arranged on the main outlet face 152 of the top operating end 15 of the main tube body, and when entering the surgical area along the operation path, the camera device enters the surgical area earlier than the negative pressure operation outlet 112; through the above arrangement, it can be ensured that after entering the surgical area, the situation of the surgical area can be observed in the fastest way, and adjustments can be made according to the observation to avoid unnecessary tissue damage. Especially for the thin mucosa at the bottom of the maxillary sinus, the protective effect is more significant.

[0084] More preferably, the camera device and the negative pressure operation outlet 112 are arranged at different positions on the main outlet face 152 of the top operating end 15 of the main tube body, without overlapping and in a longitudinal arrangement, which can ensure that the situation of the surgical area can be observed in the smallest entering path, and the damage can be avoided to the greatest extent.

[0085] More preferably, referring to FIG. 5, the orientation of the camera device is consistent with that of the negative pressure operation outlet 112; the longitudinal central axis 153 of the camera device and the negative pressure operation outlet 112 is consistent. This can ensure that the video acquisition module 2 can shoot the field of view directly opposite the surgical area, reducing the observation error. Referring to FIGS. 10 and 11, the top operating end 15 of the main tube body is provided with a containing cavity 192 for accommodating the camera device; the video acquisition module 2 is embedded in the containing cavity 192. Through the embedded arrangement, the camera can be fixed inside the top operating end 15 of the main tube body. The data cable channel 12 is arranged in the main tube body 1 for accommodating the power cable and data transmission line of the video acquisition module 2; through the power cable and data transmission line, the power supply and data transmission of the video acquisition module 2 are completed; it can also be an optical fiber, and three-dimensional imaging can be achieved through two to three cameras. Through this arrangement, even if a large amplitude bending occurs, it will not affect the normal shooting of the video acquisition module 2 at the front end. This arrangement cooperates with the main tube body 161 and the hand-held sleeve 162 arranged at an angle to solve the problem of how to arrange the video acquisition module 2 in a channel with a large bending. The camera module 21 and the illumination assembly are arranged transversely; the illumination structure 22 is arranged on the left and right sides of the camera module 21. Through this arrangement, the situation of the surgical area can be observed at the smallest entering distance. Note: transverse is the direction perpendicular to the axial direction of the main tube body 1.

[0086] More preferably, the total outlet 151 on the top operating end 15 of the main body is oriented 45°-180°, preferably 90°, i.e. perpendicularly, to the axis of the main body body portion 161. The perpendicular arrangement ensures that the operating structure can observe the area to the side of the main body 1.

[0087] The frontmost total outlet 151 on the top operating end 15 of the main body includes the negative pressure operating outlet 112, and the plane where the total outlet 151 ends defines the main outlet face 152 of the top operating end 15 of the main body.

The overall pipe diameter of the top operating end 15 of the main body is consistent, and the diameter of the top operating end 15 of the main body is not less than the diameter of the main body 1. The outer side wall of the transition between the top operating end 15 of the main body and the main body 1 is provided with a rounded corner, which can effectively prevent the tissue from being scratched. More preferably, the main body 1 is cylindrical or elliptical. The total outlet 151 on the top operating end 15 of the main body is oriented perpendicularly to the longitudinal axis of the main body 1, and the main outlet face 152 is tangent to the cylindrical face of the main body body portion 161. This arrangement ensures that the size of the main body 1 does not change due to the arrangement of the side total outlet 151, and ensures smooth entry of the entire instrument.

[0088] More preferably, referring to FIG. 15, the negative pressure operating channel 11 extends along the longitudinal axis of the main body body portion 161 through the main body connecting portion 163, turns at the top of the main body 1 to the top operating end 15 of the main body, and ends at the negative pressure operating outlet 112. The size of the negative pressure operating channel 11 in the main body 1 is consistent, or slightly larger at the total outlet 151. This arrangement ensures the continuity and consistency of the operating process of the operating tool.

[0089] More preferably, the overall path of all channels in the main body 1 is consistent, but the size of the channels can be slightly larger at the total outlet 151. This arrangement can concentrate the outlets of all channels on the main outlet face 152.

[0090] More preferably, referring to FIGS. 1-2, the maxillary sinus mirror further comprises,

[0091] A hand-held sleeve 162 for the operator to hold and complete the operating action, which is connected to the main body body portion 161;

[0092] More preferably, the stability of the maxillary sinus mirror is controlled by holding the hand-held sleeve 162.

[0093] More preferably, the outer diameter of the hand-held sleeve 162 is of a size that is convenient for gripping. More preferably, the size of the hand-held sleeve 162 is larger than that of the main body 1, and the hand-held sleeve 162 is provided with channels consistent with the main body 1. The cross-sectional area of the hand-held sleeve 162 is greater than or equal to the cross-sectional area of the main body 1, and the channels in the main body 1 continue into the hand-held sleeve 162.

[0094] More preferably, the convenience of operation can be increased by changing the angle, material, etc. of the handheld sleeve 162.

[0097] More preferably, the angle between the main pipe body 161 and the handheld sleeve 162 ranges from 0 to 180 degrees; various angles can be connected to meet the requirements of different surgical areas for angles.

[0130] More preferably, the lateral liquid jet channel 172 and the lateral air jet channel 174 are symmetrically arranged on both sides of the video capture module 2; such an arrangement can more evenly complete the flushing and blow-drying actions.

[0131] On the basis of the above-mentioned embodiments, with reference to FIG. 13, FIG. 14, FIG. 15, FIG. 16; the problem of how the various channels of the main pipe body 161 are connected with the rear-end equipment (such as the negative pressure device 45, the liquid supply device 43, the gas supply device 44, and the video display device 42, etc.) needs to be solved. The second ends of the liquid spraying channel 13, the gas spraying channel 14, and the data cable channel 12 are respectively connected with the extension pipes, which are the liquid spraying extension pipe 181, the gas spraying extension pipe 182, and the data cable extension pipe 183.

The first end of the handheld sleeve 162 is provided with the main pipe body end expansion part 164, which is connected with the handheld sleeve 162. The handheld sleeve 162 wraps the liquid spraying connecting pipe 1851, the gas spraying connecting pipe 1852, and the data cable connecting pipe 1853. That is, the space other than the liquid spraying connecting pipe 1851, the gas spraying connecting pipe 1852, and the data cable connecting pipe 1853 is the negative pressure channel. The space containing the liquid spraying connecting pipe 1851, the gas spraying connecting pipe 1852, and the data cable connecting pipe 1853 is separated from the negative pressure channel by the transverse partition, which forms the negative pressure connecting pipe 184 with the side wall of the negative pressure channel. The negative pressure pipe 1841 is arranged in connection with the negative pressure connecting pipe. The liquid spraying connecting pipe 1851, the gas spraying connecting pipe 1852, and the data cable connecting pipe 1853 are in sealed connection with the outer wall of the handheld end to form the total connecting pipe 185, which is connected to the liquid supply device 43, the gas supply device 44, and the video display device 42 (and the power supply of the camera device) and other equipment.

[0132] More preferably, the main pipe body end expansion part 164 is larger in outer diameter than the main pipe body body part 161, which is used to improve the firmness of the connection between the negative pressure connecting pipe 184 and the main pipe body body part 161.

[0133] More preferably, the liquid spraying extension pipe 181, the gas spraying extension pipe 182, and the data cable extension pipe 183 are arranged in a pagoda head shape, which is used to increase the tightness of the connection.

[0134] More preferably, a combined pipe wrapping the liquid spraying connecting pipe 1851 and the data cable connecting pipe 1853 is arranged. The combined pipe is connected with the control structure at the extension of the negative pressure connecting pipe 184.

[0135] More preferably, a branch connector is arranged. The first connector is connected with the negative pressure connecting pipe 184, the second connector is connected with the combined pipe, and the third connector is connected with the negative pressure suction pipe. The branch connector realizes the communication between the negative pressure suction pipe and the negative pressure channel. The branch connector realizes the purpose of leading the liquid spraying connecting pipe 1851 and the data cable connecting pipe 1853 out to the control structure.

[0136] Note: the above connecting pipe is a rubber pipe, which is a liquid jet connecting pipe 1851, a gas jet connecting pipe 1852, and a data cable connecting pipe 1853.

[0137] The application also describes an endoscopic surgery device suitable for maxillary sinus mucosa lifting and water vapor cleaning (see FIG. 17): a main pipe body 1, a hand-held sleeve 162, an operating tool, a connecting pipe, a liquid supply device 43, a gas supply device 44, a video display device 42, a control box 41 of the three devices, a negative pressure device 45, etc. It can be described as integrated by five systems, which are: an operating system, a video acquisition and display control system, a liquid jet system, a gas jet system, and a negative pressure system. The operating system includes the negative pressure operating channel 11 in the main pipe body 1 and the operating tool contained therein; the video acquisition and display control system includes the camera module 21, the lighting structure 22, the data cable channel 12 in the main pipe body 1, the data cable extension pipe 183, the data cable connecting pipe 1853, the control box 41, the video display device 42, and their switches; the control box 41 and the video display device 42 can perform real-time image transmission through wired or wireless networks; the liquid jet system includes the liquid jet channel 13 in the main pipe body 1, the liquid jet extension pipe 181, the liquid jet connecting pipe 1851, the control box 41, the liquid supply device 43, and their switches; the liquid supply device 43 is controlled by the switches; the gas jet system includes the gas jet channel 14 in the main pipe body 1, the gas jet extension pipe 182, the gas jet connecting pipe 1852, the control box 41, the gas supply device 44, and their switches; the gas supply device 44 is controlled by the switches; the negative pressure system includes the negative pressure operating channel 11 in the main pipe body 1, the lower cavity in the hand-held sleeve 162, the negative pressure extension pipe, the negative pressure connecting pipe 184, the negative pressure device 45, and their switches.

[0138] Referring to FIG. 1, four channels are arranged inside the main pipe body 1, of which the largest channel occupies about 1 / 2 of the cross-sectional area of the main pipe body 1, which is the negative pressure operating channel 11, and the remaining three channels are the liquid jet channel 13 and the gas jet channel 14 on the left and right sides, respectively, and the middle channel is for accommodating the video acquisition module 2 and its data cable channel 12. That is, the liquid, gas, and data cable pass through the liquid jet, gas jet, and data cable channel 12 of the main pipe body 1, respectively.

[0139] Referring to FIG. 1, the operating tool can be a stripping assembly 31 composed of a nickel-titanium wire with shape memory function, which is bent into a double strand. It enters the negative pressure operating channel 11 through the operating inlet 111, goes up along the negative pressure operating channel 11, and extends forward and downward from the total outlet 151. The stripping assembly 31 is irregularly circular, and the two ends of the stripping assembly 31 with shape memory are provided with operating handles 311, which facilitate pulling the stripping assembly 31 with shape memory to control the stripping of the stripping assembly 31 on the mucosa.

[0140] More specifically, the stripping component 31 can use a temperature-controlled memory wire with shape memory. When the temperature is lower than body temperature (for example, 20°C), the memory wire is a large amount of twinned monoclinic martensite phase at the microscopic level. At this time, the memory is weak, the elasticity is low, and the hardness is small. It can be easily bent into two strands with a small diameter at the bend, and it can be smoothly contracted into the negative pressure operation channel 11, making it easier to enter the negative pressure operation channel 11. After entering the body during surgery (at about 37°C), the microstructure of the stripping component 31 changes due to the higher temperature in the body, specifically from the martensite phase to the austenite phase with a cubic structure. At this time, the memory of the stripping component 31 becomes stronger, the elasticity becomes higher, the hardness becomes greater, and there is a memory trend of returning to its original shape. A shape memory effect occurs and a continuous and stable supporting force is generated. The diameter of the bend becomes larger, forming a larger stripping area, which is conducive to the stripping of the mucosa.

[0141] More preferably, warm water of varying temperatures can be supplied through the spray channel 13 as needed. If thick or tough mucosa is observed, the exfoliation assembly 31 can be flushed with human-tolerable warm water to further generate more austenite, thereby enhancing the elasticity of the exfoliation assembly 31 and facilitating exfoliation of thick and tough mucosa. If the mucosa is thin and brittle, the exfoliation assembly 31 can be flushed with human-tolerable low-temperature water or sprayed with air to partially transform the austenite into martensite, reducing its elasticity and minimizing damage to thin and brittle mucosa. By controlling the temperature and changing the memory and elasticity of the memory wire without changing the instrument, smooth exfoliation of the surgical mucosa can be achieved.

[0142] The liquid spray channel 13 and air jet channel 14 within the main body 1 are connected to a liquid supply device 43 and an air supply device 44, respectively, via a control box 41. The control box 41 adjusts the flow rate. At the main body 1's main outlet 151, lateral liquid spray channels 172 and lateral air jet channels 174 flush the video capture module 2, while forward liquid spray channels 171 and forward air jet channels 173 flush the surgical area.

[0143] The data cable in main body 1 is connected to the power supply via control box 41, which controls the parameters of camera module 21 and lighting structure 22. Images of the surgical site captured by video acquisition module 2 are input into control box 41 and transmitted via the wireless network established by control box 41 to video display device 42 for real-time display. This allows the surgeon to perform procedures under visual conditions, effectively improving surgical efficiency and avoiding the risk of maxillary sinus mucosal damage and perforation caused by blind surgery.

[0144] The control box 41 uniformly completes the regulation of liquid spraying, air jetting, and video acquisition, and can complete the foot-operated control of liquid spraying, air jetting, taking pictures and recording videos through the foot control switch 46.

[0145] The following are the surgical options for maxillary sinus floor mucosal lift:

[0146] According to the position of the maxillary sinus lifting, a suitable hole is drilled in the lateral wall of the maxillary bone or the top of the maxillary alveolar ridge to expose the mucosa of the maxillary sinus floor. The maxillary sinus lifting using the maxillary sinus mirror can be divided into the following four schemes: instrument operation method, hydraulic method, pneumatic method and combination of the above three methods.

[0147] Scheme 1: Instrument operation method of maxillary sinus lifting

[0148] Under the condition of video acquisition, the mucosa of the maxillary sinus floor in the maxillary hole is stripped and the operation area is flushed by using the stripping assembly 31, and the top operating end 15 of the main pipe body is slowly placed into the hole (at this time the stripping assembly 31 is hidden in the negative pressure operation channel 11), and when the top operating end 15 of the main pipe body reaches the operation area, it is operated under the monitoring of the video acquisition module 2. When the operating tool is a stripping assembly 31 with shape memory, the stripping assembly 31 is stretched out from the outlet of the negative pressure operation channel 11 below the top operating end 15 of the main pipe body, forward or forward and downward, which can be achieved by rotating the main pipe body 1, or operating the two side operating handles 311 with the same direction or opposite direction telescopic movement, or rotating the two side operating handles 311 to flip the position of the stripping assembly, or a combination of the above operations, to meet the requirements of stripping the mucosa of each area of the maxillary sinus floor. During the operation, the operation area and the lens surface are cleaned with liquid and gas.

[0149] Scheme 2: Hydraulic operation method of maxillary sinus lifting

[0150] Under the condition of video acquisition, the liquid spray function of the maxillary sinus mirror can be used alone to complete the maxillary sinus mucosa lifting by using the hydraulic pressure formed by the liquid spray: close the negative pressure device 45, slowly place the top operating end 15 of the main pipe body into the hole to reach the operation area, and the top of the main pipe body 1 plays the role of roughly closing the hole while meeting the observation of the video acquisition module 2, and the negative pressure operation outlet 112 of the top operating end 15 of the main pipe body still faces the side wall of the hole, without entering the maxillary sinus cavity, at this time the liquid pressure between the maxillary sinus mucosa and the maxillary sinus bone wall is formed by controlling the liquid supply device 43 to spray the liquid from the opening of the liquid spray channel 13 on the main outlet face 152, as the amount of liquid spray increases, the liquid pressure gradually increases, which can further separate the maxillary sinus mucosa around the hole from the sinus wall, at this time the main pipe body 1 can be slowly rotated or fixed until the maxillary sinus mucosa lifted by the liquid pressure reaches the predetermined height.

[0151] Scheme 3: Pneumatic operation method of maxillary sinus lifting

[0152] In the video acquisition condition, the jet function of the maxillary sinus mirror can be used alone, and the air pressure formed by the jet can complete the maxillary sinus mucosa lifting operation: close the negative pressure device 45, slowly put the top operating end 15 of the main pipe body into the bone hole to reach the operation area, the top of the main pipe body 1 plays the role of roughly closing the bone hole while meeting the observation of the video acquisition module 2, and the negative pressure operation outlet 112 of the top operating end 15 of the main pipe body still faces the bone hole side wall, and does not enter the maxillary sinus cavity. At this time, by controlling the gas supply device 44, the gas jetted from the opening of the jet channel 14 on the main outlet face 152 forms air pressure between the maxillary sinus mucosa and the maxillary sinus bottom bone wall. With the increase of the jet amount, the air pressure gradually increases, which can make the maxillary sinus mucosa around the bone hole further separate from the sinus wall. At this time, the main pipe body 1 can be slowly rotated or fixed until the maxillary sinus mucosa lifted by the air pressure reaches the predetermined height.

[0153] Scheme four: combined operation method of maxillary sinus lifting

[0154] The above three schemes can be combined in the form of not less than any two operation schemes.

[0155] The following is the implementation of the instrument suitable for the existence of cysts, polyps, pus and other lesions or foreign bodies in the maxillary sinus or other parts of the body or other tissues. The following examples take the maxillary sinus as an example, but are not limited to the maxillary sinus.

[0156] Taking the maxillary sinus as an example, when there are cysts, polyps, pus and other lesions or foreign bodies in the sinus, the lesions are selected according to the position of the maxillary sinus cavity to open a window in the appropriate maxillary bone lateral wall position, expose and incise the maxillary sinus mucosa. Put the top operating end 15 of the main pipe body into the maxillary sinus cavity, check the operation area and determine the position of the lesion under the monitoring of the video acquisition module 2, and use the maxillary sinus mirror to perform the operation of the lesion or foreign body in the maxillary sinus- various operation tools extended through the negative pressure operation channel 11 are used for operation. According to the difference of the operation tools, not less than nine specific operation methods can be divided: scheme five-scheme thirteen.

[0157] Scheme five: operation method of applying puncture and injection assembly 32

[0158] When there is a lesion in the maxillary sinus that needs to be punctured and injected, the puncture and injection assembly 32 is extended from the top operating end 15 of the main pipe body 1 to the puncture and injection site (see Figures 1 and 18), and the sampling site is checked under the monitoring of the video acquisition module 2 to fully understand the size, shape, boundary, blood vessels, etc. of the lesion. The puncture and injection assembly 32 is extended through the operation inlet 111 along the negative pressure operation channel 11 to the negative pressure operation outlet 112, the length of the assembly is adjusted to the target position, the main pipe body 1 is adjusted, the lesion tissue is punctured from different angles, and the surgical area is cleaned by liquid spraying, gas spraying, and the use of negative pressure suction in the negative pressure operation channel 11. The specimen obtained by puncture can be subjected to pathological examination by smear or liquid-based cytology method; in this scheme, drug injection and other operations can also be performed on the lesion site.

[0159] Scheme six: operation method of applying the clamping assembly 33

[0160] When there is necrotic tissue or foreign matter in the maxillary sinus, the clamping assembly 33 is extended from the top operating end 15 of the main pipe body 1 to the vicinity of the foreign matter in the maxillary sinus (see Figures 1 and 19), and the liquid and / or gas are used to flush and clean the surgical field and the video acquisition module 2 by controlling the liquid supply device 43 and the gas supply device 44 through the control box 41 under the monitoring of the video acquisition module 2, to ensure that the surgical field is clear. The location of the foreign matter is determined, and then the clamping assembly 33 is extended along the operation inlet 111, the negative pressure operation channel 11 to the negative pressure operation outlet 112, and the operation handle 311 is controlled to clamp the foreign matter, and the main pipe body 1 is slowly pulled out to the outside of the body along with the operating end 15 of the top end.

[0161] In this scheme, the clamping assembly can also be replaced by a cutting assembly 34 or a twisting assembly 35 to achieve corresponding surgical treatment.

[0162] Scheme seven: operation method of applying the sleeve assembly 36

[0163] When a foreign matter such as a broken root falls into the maxillary sinus, the sleeve assembly 36 is extended from the top operating end 15 of the main pipe body 1 into the maxillary sinus (see Figures 1 and 22), and the liquid and / or gas are used to flush and clean the surgical field and the video acquisition module 2 by controlling the liquid supply device 43 and the gas supply device 44 through the control box 41 under the monitoring of the video acquisition module 2, to ensure that the surgical field is clear. The location of the foreign matter is determined, and then the sleeve assembly 36 is extended along the operation inlet 111, the negative pressure operation channel 11 to the negative pressure operation outlet 112, and the operation handle 311 is controlled to sleeve the foreign matter, and the main pipe body 1 is slowly pulled out to the outside of the body along with the operating end 15 of the top end.

[0164] In addition, the following scenarios can also apply this device: when there is cerumen or foreign matter in the external auditory canal, the device can be used to remove it.

[0165] Scheme eight: operation method of applying the electrotome assembly 37

[0166] When there is a lesion such as a polyp in the sinus cavity, the electrotome assembly 37 can be extended from the outlet of the negative pressure operation channel 11 below the top operating end 15 of the main body 1 to the vicinity of the lesion such as a polyp.

[0167] Scheme Nine: Operation method using laser assembly 38
