Description
Technical Field
[0001] The utility model relates to the field of endoscopic surgery, and particularly relates to a device for endoscopic surgery. Background Art
[0002] In endoscopic (flexible endoscope) surgery, there are usually a handle and an outer sheath. The handle is used to drive the sheath and make the distal end of the sheath reach the target area.
[0003] In traditional endoscopic (flexible endoscope) surgery, to meet the requirements of reducing the use cost and avoiding cross-infection, the outer sheath is usually reused after disinfection and the number of reuse times is limited. It is known that the outer sheath is detachably connected to the handle housing, so that the disinfected outer sheath can be installed on the handle each time endoscopic (flexible endoscope) surgery is performed. The existing counting method for the use times of the outer sheath still stays in the original manual counting. When multiple different outer sheaths are placed in the same tray, medical staff are very likely to take the outer sheaths wrongly, resulting in the outer sheaths close to the use times limit being reused repeatedly, which poses a safety hazard. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the defect that the outer sheath cannot be effectively counted in the prior art, and provide a device for endoscopic surgery.
[0005] The utility model solves the above technical problem through the following technical solutions:
[0006] A device for endoscopic surgery, the device for endoscopic surgery includes a handle and an outer sheath detachably connected to the handle. The device for endoscopic surgery further includes:
[0007] A reading and writing part, the reading and writing part is arranged in the handle and located at the connection part between the handle and the outer sheath;
[0008] A label part, the label part is arranged in the outer sheath. The label part is arranged corresponding to the reading and writing part along the installation direction of the outer sheath and the handle. When the outer sheath is connected to the handle, the reading and writing part is used to read the connection times, the diameter and length of the outer sheath on the label part and record a new connection time on the label part.
[0009] In this solution, by setting up a reading and writing unit to read the connection times on the tag unit, it is more intelligent compared to the manual counting method, and the connection times can be transmitted to the network for networking, so that maintenance personnel can promptly scrap the outer sleeve that has reached the reuse times to avoid cross-infection that may be caused by repeated use, ensuring the safety of patients during use. Additionally, the reading and writing unit can also update the new connection times on the tag unit and record the connection times of the outer sleeve in a timely manner to ensure the accuracy of counting. Meanwhile, in addition to reading the connection times, other information of the outer sleeve can also be read, such as the type of the outer sleeve, diameter information, and length information, so as to effectively feedback to the operator whether the outer sleeve is correctly selected before the handle is connected to the outer sleeve.
[0010] Preferably, the reading and writing unit is a contact type reading and writing component, and the tag unit is a contact type tag;
[0011] Or the reading and writing unit is a non-contact type reading and writing component, and the tag unit is a non-contact type tag.

[0013] Preferably, the handle includes an output unit, the control board of the handle is electrically connected to the rocker mechanism, and the output unit is connected to the outer sleeve.
[0014] In this solution, by setting up a rocker mechanism, the rocker mechanism transmits signals to the control board to complete the operating gesture of the operator for adjusting the end of the outer sleeve. Compared with the method of using two dial wheels to combine and adjust the end of the outer sleeve, on the one hand, it prevents the accidental touch of the two dial wheels from affecting the actual position of the end of the outer sleeve. On the other hand, by adjusting the offset angle of the rocker mechanism, the end of the outer sleeve can move at different speeds, achieving more precise or faster movement.
[0015] Preferably, a first encoder is provided at the connection between the handle and the rocker mechanism.
[0016] In this solution, through the above settings, the offset angle of the rocker mechanism can be converted into a signal that the handle can recognize.
[0017] Preferably, the output unit includes at least two driving units, each driving unit includes a motor and an output shaft, and the output shaft is connected to the outer sleeve through a concave-convex structure.
[0018] In this solution, through the above settings, the transmission driving method between the dial wheel and the outer sleeve is replaced by the driving method of the motor to reduce the operation difficulty.
[0019] Preferably, the driving unit further includes a speed reducer, and the speed reducer is connected in series with the motor and is located between the motor and the output shaft.
[0020] In this solution, through the above settings, the stability of the operation is improved.
[0021] Preferably, the drive unit further includes a second encoder, and the second encoder is arranged between the speed reducer and the end of the handle facing the outer sleeve.
[0022] In this solution, through the above settings, the operation accuracy is achieved.
[0023] Preferably, a button is further arranged on the rocker mechanism, the button is electrically connected to the control board, and the outer sleeve performs one or more functions of suction, air supply, flushing, image screenshot, and image freezing through the button.
[0024] In this solution, through the above settings, the integration degree of the handle is improved, and multiple functions of the handle are realized.
[0025] Preferably, a positioning pin is further arranged on the handle corresponding to the connection part with the outer sleeve, and a pin hole is arranged in the outer sleeve corresponding to the positioning pin.
[0026] In this solution, through the above settings, the connection accuracy when the outer sleeve is connected to the handle is improved. When the positioning pin and the pin hole are matched, it can also ensure that the label part and the reading and writing part correspond to each other, avoiding the situation of reading and writing failure.
[0027] Preferably, the handle and the outer sleeve are connected through a clamping structure. When the clamping structure is matched, the sensor on the handle sends a signal that the connection between the handle and the outer sleeve is successful to the control board.
[0028] In this solution, through the above settings, the operator is prompted after the handle and the outer sleeve are effectively connected, avoiding the risk of starting the operation due to the situation that the outer sleeve cannot move following the operation of the handle when the connection fails.
[0029] The positive and progressive effects of the present utility model are as follows: By setting a reading and writing part to read the connection times on the label part, the present utility model is more intelligent compared with the manual counting method, and the connection times can be transmitted to the network connected to the Internet, so that maintenance personnel can promptly scrap the outer sleeve that has reached the repeated use times to avoid cross-infection that may be caused by repeated use multiple times, ensuring the safety of patients during use. In addition, the reading and writing part can also update the new connection times to the label part on the label part and record the connection times of the outer sleeve in a timely manner, ensuring the accuracy of counting. At the same time, in addition to reading the connection times, other information of the outer sleeve can also be read, such as the type of the outer sleeve, diameter information, and length information, so as to effectively feedback to the operator whether the outer sleeve is correctly selected before the handle is connected to the outer sleeve.

[0053] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the accompanying drawings.
[0054] This embodiment provides a device for endoscopic surgery, and the specific structure is as Figure 1 , Figure 2 and Figure 3 shown. The device for endoscopic surgery includes a handle 1 and an outer sleeve 2 detachably connected to the handle 1. The device for endoscopic surgery further includes:
[0055] A reading and writing unit 11, which is arranged inside the handle 1 and located at the connection part between the handle 1 and the outer sleeve 2;
[0056] A tag unit (not shown in the figure), which is arranged inside the outer sleeve 2. The tag unit is arranged corresponding to the reading and writing unit 11 along the installation direction of the outer sleeve 2 and the handle 1. When the outer sleeve 2 is connected to the handle 1, the reading and writing unit 11 is used to read the connection times, the diameter and length of the outer sleeve 2 on the tag unit and record a new connection time on the tag unit.
[0057] Specifically, the reading and writing unit 11 is arranged at the end of the handle 1 for connecting with the outer sleeve 2. The reading and writing unit 11 can be an interface device IFD in the prior art, while the tag unit is arranged at the end of the outer sleeve 2 for connecting with the handle 1, and the tag unit is a radio frequency tag in the prior art. After the handle 1 and the outer sleeve 2 are connected, the reading and writing unit 11 records the newly added connection times on the tag unit to update the connection times on the tag unit, so as to record the connection times of the outer sleeve 2 in time and ensure the accuracy of counting. Compared with the manual counting method, it is more intelligent and the connection times can be transmitted to the connected network through the networking of the tag unit. In addition, when the reading and writing unit 11 reads and writes the tag unit, it can also identify the originally recorded connection times on the tag unit. The originally recorded connection times on the tag unit can be fed back to the operator through the handle 1, or when the tag unit transmits the connection times to the connected network, the maintenance personnel can view them in time without the outer sleeve 2 being connected to the handle 1, so that the maintenance personnel can scrap the outer sleeve 2 that has reached the repeated use times in time, avoiding cross-infection that may be caused by repeated use for many times and ensuring the use safety of patients.
[0058] At the same time, in addition to reading the connection times, the reading and writing unit 11 in this embodiment can also read other information of the outer sleeve 2, such as the type, diameter information and length information of the outer sleeve 2, so as to effectively feedback to the operator whether the outer sleeve 2 is correctly taken before the handle 1 is connected to the outer sleeve 2.
[0059] In this embodiment, the reading and writing unit 11 is a non-contact reading and writing component, and the tag unit is a non-contact tag. Taking the reading and writing unit 11 as an RFID antenna and the tag unit as an RFID tag as an example for illustration. It can be understood that the tag unit is arranged inside the outer sleeve 2. The tag unit is an RFID tag, and the reading and writing unit 11 is an RFID antenna. The RFID tag corresponds to the RFID antenna after the handle 1 is connected to the outer sleeve 2, and the RFID tag in the outer sleeve 2 is read and written.
[0060] In another embodiment, the reading and writing unit 11 is a contact reading and writing component, and the tag unit is a contact tag. For example, in the prior art, a pogopin and a pogopin interface, the reading and writing unit 11 is a pogopin, and the tag unit is a pogopin interface. Its purpose is also to realize the reading and writing of the information of the outer sleeve 2. This is the prior art and will not be elaborated here too much.
[0061] Furthermore, as Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, in this embodiment, the handle 1 includes an output part 13. The control board (not shown in the figure) of the handle 1 is electrically connected to the rocker mechanism 3, and the output part 13 is connected to the outer sleeve 2.
[0062] Specifically, the rocker mechanism 3 is electrically connected to the control board. The rocker mechanism 3 is a Hall rocker in the prior art. It can be understood that the rocker mechanism 3 transmits signals to the control board to complete the operation gesture of the operator to adjust the end of the outer sleeve 2. The signal transmission method is the prior art. This embodiment does not improve its signal logic. The method of driving the outer sleeve 2 to move through the rocker mechanism 3, compared with the traditional method of setting two dials stacked for input, the rocker mechanism 3 does not need to operate different dials step by step in two steps, preventing accidental touch and the input position of a certain dial from changing, reducing the operation difficulty of the handle 1. At the same time, compared with the input method of two dials, the rocker mechanism 3 does not need to lock the dials and does not need to unlock before adjusting the dials next time. Only the operator needs to drive the rocker mechanism 3 to rotate to realize the input of the positions of the two dials, and there is no need to reach the target area by superimposing the movements in two directions, realizing "point and shoot", and it is not easy to get tired under repeated operations.
[0063] In this embodiment, a first encoder 4 is provided at the connection between the handle 1 and the rocker mechanism 3. It can be understood that the signals input during the rotation of the rocker mechanism 3 need to be encoded by the first encoder 4 to facilitate the effective recognition of the handle 1, realizing the conversion of the offset angle of the rocker mechanism 3 into a signal that the handle 1 can recognize. At the same time, the presence of the first encoder 4 makes the signals input to the handle 1 more accurate. Compared with the method of inputting to the handle 1 through the multi-link structure transmission, it can drive the end of the outer sleeve 2 away from the handle 1 more precisely.
[0064] In this embodiment, the output unit 13 includes at least two driving units 5. The driving unit 5 includes a motor 51 and an output shaft 52. The output shaft 52 is connected to the outer sleeve 2 through a concave-convex structure.
[0065] Specifically, the output unit 13 is disposed inside the housing of the handle 1. The output unit 13 includes at least two driving units 5. The driving units 5 are arranged along the height direction of the housing and include a motor 51 and an output shaft 52 connected in series with the motor 51. It can be understood that the output shaft 52 extends toward the end of the outer sleeve 2 connected to the handle 1. A protruding portion 521 is provided in the radial direction of the output shaft 52. The protruding portion 521 is a flange with a trapezoidal structure to cooperate with the transmission structure in the outer sleeve 2 that drives the outer sleeve 2 away from the end of the handle 1. Of course, in other embodiments, the protruding portion 521 can also be provided in the outer sleeve 2, and a groove cooperating with the protruding portion 521 is provided on the output shaft 52 to form a concave-convex structure and connect the output shaft 52 to the outer sleeve 2 through the concave-convex structure. By setting the power for transmitting the rocker mechanism 3 in the handle 1 as the motor 51, the motor 51 can be a servo motor in the prior art, so that when the handle 1 drives the end of the outer sleeve 2 to move, different speed movements, as well as more precise or faster movements, can be achieved.
[0066] In this embodiment, the driving unit 5 further includes a speed reducer 53. The speed reducer 53 is connected in series with the motor 51 and is located between the motor 51 and the output shaft 52.
[0067] Specifically, the speed reducer 53 is disposed between the motor 51 and the output shaft 52. When the motor 51 receives a signal from the rocker mechanism 3 through the control board and the first encoder 4, the motor 51 rotates and drives the output shaft 52 to rotate. At the same time, according to the offset angle of the rocker mechanism 3, the motor 51 is rotated through the control board, thereby driving the end of the outer sleeve 2 away from the handle 1 to move. The outer sleeve 2 can swing up, down, left, and right corresponding to the rocker mechanism 3, which is more user-friendly. The speed reducer 53 is a speed reducer structure in the prior art and will not be elaborated here.
[0068] In this embodiment, the driving unit 5 further includes a second encoder 6. The second encoder 6 is disposed between the speed reducer 53 and the end of the handle 1 facing the outer sleeve 2. It can be understood that the signal output by the rotation of the motor 51 needs to be encoded by the second encoder 6 to facilitate the effective recognition of the output shaft 52, so as to convert the offset angle of the rocker mechanism 3 into a signal that the output shaft 52 can recognize. At the same time, the presence of the second encoder 6 makes the signal input to the output unit 13 more accurate. Compared with the way of transmitting the signal to the output unit 13 through the multi-link structure transmission, the movement of the outer sleeve 2 away from the end of the handle 1 can be driven more precisely.
[0069] In this embodiment, both the first encoder 4 and the second encoder 6 are of the structure of an encoder head and an encoder magnetic ring to achieve smooth reading and writing of signals and input and output of signals. This is prior art and will not be elaborated here.
[0070] In other embodiments, a brake (not shown in the figure) is further provided on the periphery of the driving unit 5. The brake is a braking structure in the prior art for locking the output shaft 52, so as to lock the output shaft 52 through the brake after the driving outer sleeve 2 reaches the target area and keep the position of the end of the outer sleeve 2 unchanged.
[0071] In this embodiment, a button 31 is further provided on the rocker mechanism 3. The button 31 is electrically connected to a control board (not shown in the figure). The outer sleeve 2 performs one or more functions of suction, air supply, flushing, image screenshot, and image freezing through the button 31. It can be understood that the button 31 sends a signal to the control board, and the control board transmits the signal to the corresponding functional area at the end of the outer sleeve 2 to achieve the above functions. The signal transmission between the button 31 and the control board in this embodiment belongs to the prior art, and its transmission logic has not been modified, so it will not be elaborated here. By setting the button 31 to integrate the functions, the integration degree of the handle 1 is improved, and multiple functions of the handle 1 are realized.
[0072] In this embodiment, a positioning pin 7 is further provided on the handle 1 corresponding to the connection part with the outer sleeve 2, and a pin hole is provided in the outer sleeve 2 corresponding to the positioning pin 7.
[0073] Specifically, the positioning pin 7 is arranged along the connection direction of the outer sleeve 2 and the handle 1, and a guiding part is provided at the end of the positioning pin 7 away from the handle 1. The guiding part is a chamfer structure in the prior art, which can be a right-angle chamfer or a rounded chamfer, and will not be elaborated here. When the positioning pin 7 cooperates with the pin hole, in addition to ensuring that the outer sleeve 2 and the handle 1 will not shake after connection, it can also guide the outer sleeve 2 during connection, so that the outer sleeve 2 can be accurately connected to the handle 1, prevent deviation, ensure that the label part corresponds to the reading and writing part 11, and avoid the situation of reading and writing failure. In this embodiment, two positioning pins 7 are provided. In other embodiments, multiple positioning pins 7 can also be provided to improve the connection accuracy.
[0074] In this embodiment, the handle 1 and the outer sleeve 2 are connected through a clamping structure 8. When the clamping structure 8 is engaged, a sensor (not shown in the figure) on the handle 1 sends a signal to the control board indicating that the handle 1 and the outer sleeve 2 are successfully connected.
[0075] Specifically, the snap connection structure 8 is a snap structure in the prior art. A snap groove is provided corresponding to the snap connection structure 8 and is used to cooperate with the snap connection structure 8. It should be noted that in this embodiment, the snap connection structure 8 can be provided on the handle 1, and the snap groove is correspondingly provided in the outer sleeve 2. In other embodiments, the snap connection structure 8 can also be provided in the outer sleeve 2, and correspondingly, the snap groove is provided on the handle 1. It can be understood that the snap connection structure 8 is also connected to the transmission structure. When the snap connection structure 8 is in place in cooperation with the snap groove, the force transmitted from the outer sleeve 2 to the snap connection structure 8 is transmitted to the sensor on the handle 1 through the transmission structure, so as to prompt the operator that the handle 1 is connected to the outer sleeve 2 in place by sending a connection success signal to the control board, avoiding the situation that the outer sleeve 2 cannot move following the operation of the handle 1 when the connection fails. This can prevent the risk of starting the operation when the connection is not in place.
[0076] Of course, in other embodiments, a buzzer or a sound-light-voice reminder structure can also be provided to effectively remind the operator. This is prior art and will not be elaborated here.
[0077] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
