[0005] In existing gynecological laparoscopic surgeries, the operation of switching instruments is relatively complex and inconvenient for medical staff. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a quick-change interface device for gynecological laparoscopic surgical instruments, which solves the technical problem that medical personnel face complex operations and inconvenience when switching instruments in existing gynecological laparoscopic surgeries.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A quick-change interface device for gynecological laparoscopic surgical instruments includes a handle and multiple magnetic sleeves. Each magnetic sleeve is equipped with an electrosurgical head. A retaining plate is evenly rotated and mounted on the handle. The electrosurgical head has evenly spaced slots. A tension spring is installed between the retaining plate and the handle. A spring is installed between the handle and the unlocking ring. A male power supply connector is fixedly mounted on the electrosurgical head. A female power supply connector is fixedly mounted inside the handle.

[0009] Preferably, a waste liquid hopper is fixedly installed at the bottom end of the magnetic sleeve.

[0010] Preferably, a liquid storage tank is fixedly installed on the side end of the waste liquid hopper.

[0011] Preferably, a liquid supply ring is fixedly installed on the magnetic sleeve.

[0012] Preferably, a liquid supply pipe is fixedly installed on the liquid supply ring.

[0013] Preferably, a water pump is fixedly installed at the end of the liquid supply pipe.

[0014] Preferably, distance sensors are evenly and fixedly installed on the liquid storage tank.

[0015] Preferably, a control panel is fixedly installed inside the liquid storage tank.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When using the device, align the handle with the scalpel head and press down firmly. The side of the scalpel head will push open the retaining plate, causing it to rotate outward against the tension of the spring. When the scalpel head is inserted to its limit position, the retaining plate will return to its original position under the tension of the spring and lock into the slot. At this time, the female power connector will also be inserted into the male power connector to supply power to the scalpel head, completing the connection between the scalpel head and the handle. Then, pull the handle outward to remove the scalpel head from the magnetic sleeve for use. After use, insert the scalpel head back into the magnetic sleeve. The magnetic sleeve will then magnetically hold the metal of the scalpel head in place. The handle is magnetically attached, and then the finger pushes the unlocking ring downwards, causing the unlocking ring to slide downwards against the spring force. The spring will then pass through the inclined surface of the locking plate, pushing the locking plate to rotate outwards against the tension of the spring. At this point, pulling the handle outwards will separate the electrosurgical head from the handle. In gynecological laparoscopic surgery, medical personnel can connect the electrosurgical head by pressing the handle onto it. After inserting the electrosurgical head back into the magnetic sleeve, pushing the unlocking ring will separate the head. This can be operated with one hand and allows for quick replacement of different sizes of electrosurgical heads during surgery, achieving a user-friendly effect.

[0018] 2. During use, the distance sensor will detect whether the electrosurgical head is in the magnetic sleeve and transmit the detection data to the control board. When the electrosurgical head is removed and reinserted, the control board will activate the corresponding water pump. The water pump will deliver the disinfectant inside the storage tank to the supply ring along the supply pipe, and then the supply ring will evenly spray it onto the electrosurgical head to clean and disinfect the used electrosurgical head. The used disinfectant will be discharged along the waste liquid hopper to the waste liquid storage mechanism (the waste liquid hopper is connected to the waste liquid storage mechanism through a conduit), thus achieving the effect of automatically cleaning and disinfecting the used electrosurgical head.

Detailed Implementation

[0028] This application provides a quick-change interface device for gynecological laparoscopic surgical instruments, effectively solving the technical problem that the operation of changing instruments in existing gynecological laparoscopic surgeries is relatively complicated and inconvenient for medical personnel. In use, the handle is aligned with the electrosurgical head and pressed down firmly. The side of the electrosurgical head will push open the retaining plate, causing the retaining plate to rotate outward against the tension of the spring. When the electrosurgical head is inserted to its limit position, the retaining plate will reset under the tension of the spring and lock into the slot. At this time, the female power supply connector will also be inserted into the male power supply connector to supply power to the electrosurgical head, completing the connection between the electrosurgical head and the handle. Then, pulling the handle outward allows the electrosurgical head to be removed from the magnetic sleeve for use. After use, the electrosurgical head is inserted back into the magnetic sleeve, which will magnetically attract the metal handle of the electrosurgical head. Then, pushing the unlocking ring downward with a finger causes the unlocking ring to slide downward against the spring force. The spring will then push the retaining plate against the inclined surface of the retaining plate. The tension spring rotates outwards, allowing the handle to be pulled outwards to separate the electrosurgical head from the handle. In gynecological laparoscopic surgery, medical personnel can connect the electrosurgical head by pressing the handle onto it. After inserting the electrosurgical head back into the magnetic sleeve, pushing the unlocking ring completes the separation. This allows for one-handed operation and quick replacement of different sizes of electrosurgical heads during surgery, achieving ease of use. During use, a distance sensor detects whether the electrosurgical head is in the magnetic sleeve and transmits the detection data to the control board. When the electrosurgical head is removed and reinserted, the control board activates the corresponding water pump. The pump delivers disinfectant from the storage tank along the supply pipe to the supply ring, which then sprays it evenly onto the electrosurgical head, cleaning and disinfecting it. The used disinfectant is discharged along the waste liquid hopper to the waste liquid storage mechanism (connected to the waste liquid storage mechanism via a conduit), achieving automatic cleaning and disinfection of the used electrosurgical head.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the technical solution in this application embodiment effectively solves the technical problem that the operation of switching instruments is relatively complicated and inconvenient for medical personnel in existing gynecological laparoscopic surgery. The overall idea is as follows:

[0031] To address the problems existing in the prior art, this utility model provides a quick-change interface device for gynecological laparoscopic surgical instruments, including a handle 3 and multiple magnetic sleeves 1. Each magnetic sleeve 1 is equipped with an electric knife head 2. A retaining plate 4 is evenly rotated and installed on the handle 3. The electric knife head 2 is evenly provided with retaining grooves 5. A tension spring 6 is installed between the retaining plate 4 and the handle 3.

[0032] A spring 8 is installed between the handle 3 and the unlocking ring 7. A power supply male connector 9 is fixedly installed on the electric knife head 2. A power supply female connector 11 is fixedly installed inside the handle 3. A waste liquid hopper 12 is fixedly installed at the bottom of the magnetic sleeve 1. A liquid storage tank 13 is fixedly installed at the side end of the waste liquid hopper 12.

[0033] A liquid supply ring 14 is fixedly installed on the magnetic sleeve 1, a liquid supply pipe 15 is fixedly installed on the liquid supply ring 14, a water pump 16 is fixedly installed at the end of the liquid supply pipe 15, distance sensors 17 are evenly fixedly installed on the liquid storage tank 13, and a control board 18 is fixedly installed inside the liquid storage tank 13.

[0034] Magnetic sleeve 1: Installed on the electric knife head 2, it uses magnetic force to attract the metal handle of the electric knife head 2, thus fixing the electric knife head 2. At the same time, its bottom end is connected to the waste liquid hopper 12, its side is connected to the liquid storage tank 13, and its surface is equipped with a liquid supply ring 14.

[0035] Electrosurgical head 2: As the execution component for surgical operations, it is connected to the handle 3 and powered by the male power supply head 9 and the female power supply head 11 to perform surgical operations. Its surface has a slot 5, which cooperates with the card plate 4 on the handle 3 to achieve connection and fixation with the handle 3. After use, it is inserted back into the magnetic sleeve 1 for cleaning and disinfection.

[0036] Handle 3: A component operated by medical personnel. It connects to the electrosurgical head 2 by pressing and separates from the electrosurgical head 2 by pushing the unlocking ring 7, enabling quick replacement of the electrosurgical head 2. It has a power supply female head 11 installed inside to supply power to the electrosurgical head 2, and also provides installation positions for components such as the locking plate 4, tension spring 6, unlocking ring 7, and spring 8.

[0037] The locking plate 4 is rotatably mounted on the handle 3. When the electric knife head 2 is inserted, its side pushes open the locking plate 4. The locking plate 4 rotates outward against the tension of the tension spring 6. After the electric knife head 2 is inserted into place, the locking plate 4 resets under the tension of the tension spring 6 and locks the slot 5 on the electric knife head 2, realizing the locking connection between the handle 3 and the electric knife head 2. When the unlocking ring 7 is pushed, the unlocking ring 7 pushes the locking plate 4 to rotate outward again through the action of the inclined surface of the locking plate 4, releasing the lock between the handle 3 and the electric knife head 2.

[0038] Slot 5: It is located on the electrosurgical head 2 and works with the retaining plate 4. When the retaining plate 4 locks the slot 5, it can prevent the electrosurgical head 2 from accidentally falling off the handle 3 and ensure the stability of the connection between the two during the surgical operation.

[0039] Tension spring 6: Installed between the clamping plate 4 and the handle 3, it provides inward tension to the clamping plate 4 so that it can automatically reset and lock the slot 5 after the electric knife head 2 is inserted into the position, maintaining the stability of the connection between the handle 3 and the electric knife head 2. When unlocking, it resists the thrust transmitted by the unlocking ring 7 through the inclined plane, so that the clamping plate 4 overcomes its tension and rotates outward.

[0040] Unlocking ring 7: A spring 8 is installed between the handle 3 and the unlocking ring 7. When the finger pushes the unlocking ring 7 downward, it slides downward against the elastic force of the spring 8. Through the interaction with the inclined surface of the locking plate 4, the locking plate 4 is pushed to rotate outward, thereby releasing the locking connection between the handle 3 and the electric knife head 2, making it easy to separate the handle 3 from the electric knife head 2.

[0041] Spring 8: Installed between handle 3 and unlocking ring 7, it provides an upward elastic force to unlocking ring 7, keeping it in its initial position when no external force is applied. When a finger pushes unlocking ring 7, spring 8 is compressed and stores energy. After the external force disappears, spring 8 returns to its original shape and pushes unlocking ring 7 to reset.

[0042] Male power connector 9: It is fixedly installed on the electric knife head 2 and cooperates with the female power connector 11 inside the handle 3. When the handle 3 is connected to the electric knife head 2, the female power connector 11 is inserted into the male power connector 9 to provide power to the electric knife head 2 and ensure that the electric knife head 2 works normally.

[0043] Power supply female connector 11: It is fixedly installed inside the handle 3 and connects with the power supply male connector 9 to supply power to the electrosurgical head 2, ensuring a stable power supply to the electrosurgical head 2 during surgical operations;

[0044] Waste liquid hopper 12: It is fixedly installed at the bottom of the magnetic sleeve 1 to collect the disinfectant used after being sprayed from the liquid supply ring 14 onto the electric knife head 2, and discharge it to the waste liquid storage mechanism through the conduit to realize the collection and discharge of waste liquid;

[0045] Storage tank 13: Fixedly installed on the side of waste liquid hopper 12, it stores disinfectant for cleaning and disinfecting electric knife head 2, providing a source of disinfectant for the disinfection process. At the same time, a control board 18 is installed inside and a distance sensor 17 is installed on the surface to provide hardware support for controlling the disinfection process.

[0046] Liquid supply ring 14: It is fixedly installed on the magnetic sleeve 1 and connected to the liquid supply pipe 15. It receives the disinfectant delivered by the water pump 16 from the liquid supply pipe 15 and sprays it evenly onto the electric knife head 2 that is inserted back into the magnetic sleeve 1, so as to clean and disinfect the electric knife head 2.

[0047] Liquid supply pipe 15: One end is fixedly connected to the liquid supply ring 14, and the other end is fixedly connected to the water pump 16. It serves as a channel to transport the disinfectant in the liquid storage tank 13 to the liquid supply ring 14 by the water pump 16.

[0048] Water pump 16: Fixedly installed at the end of the liquid supply pipe 15. When the control board 18 receives the signal from the distance sensor 17 that the electric knife head 2 has been inserted back into the magnetic sleeve 1, the water pump 16 is started to extract the disinfectant in the storage tank 13 and pressurize it to the liquid supply ring 14 through the liquid supply pipe 15, so as to provide power for the cleaning and disinfection of the electric knife head 2.

[0049] Distance sensor 17: It is evenly and fixedly installed on the liquid storage tank 13 to detect whether the electric knife head 2 is located in the magnetic sleeve 1, and transmits the detection data to the control board 18, so as to provide a basis for the control board 18 to determine whether to start the water pump 16 to clean and disinfect the electric knife head 2.

[0050] Control board 18: Fixedly installed inside the liquid storage tank 13, it receives detection data transmitted by the distance sensor 17. When it detects that the electric knife head 2 has been removed and reinserted into the magnetic sleeve 1, it controls the corresponding water pump 16 to start, thereby realizing automatic control of the cleaning and disinfection process of the electric knife head 2.

[0051] Working principle:

[0052] First, when using the device, align the handle 3 with the electric knife head 2 and press it down firmly. The side of the electric knife head 2 will push open the retaining plate 4, causing the retaining plate 4 to rotate outward against the tension of the tension spring 6. When the electric knife head 2 is inserted to its limit position, the retaining plate 4 will reset under the tension of the tension spring 6 and lock into the retaining groove 5. At this time, the power supply female connector 11 will also be inserted into the power supply male connector 9 to supply power to the electric knife head 2, thus connecting the electric knife head 2 and the handle 3. Then, pull the handle 3 outward to remove the electric knife head 2 from the magnetic sleeve 1 for use. After use, insert the electric knife head 2 back into the magnetic sleeve 1. The magnetic sleeve 1 will then use magnetic force to hold the electric knife head in place. The metal handle of the electrosurgical head 2 is attracted to the magnetic sleeve 1. Then, the finger is used to push the unlocking ring 7 downward, causing the unlocking ring 7 to slide downward against the elastic force of the spring 8. The spring 8 will then push the locking plate 4 outward against the tension of the tension spring 6 through the inclined surface of the locking plate 4. At this time, pulling the handle 3 outward will separate the electrosurgical head 2 from the handle 3. In gynecological laparoscopic surgery, medical staff can connect the electrosurgical head 2 by pressing the handle 3 onto the electrosurgical head 2. After inserting the electrosurgical head 2 back into the magnetic sleeve 1, pushing the unlocking ring 7 will separate the electrosurgical head 2. This can be operated with one hand and allows for quick replacement of different sizes of electrosurgical heads 2 during the operation, achieving the effect of ease of use.

[0053] In the second step, during use, the distance sensor 17 will detect whether the electrosurgical head 2 is located in the magnetic sleeve 1 and transmit the detection data to the control board 18. When the electrosurgical head 2 is removed and reinserted, the control board 18 will activate the corresponding water pump 16. The water pump 16 will transport the disinfectant inside the liquid storage tank 13 along the liquid supply pipe 15 to the liquid supply ring 14. Then, the liquid supply ring 14 will evenly spray the disinfectant onto the electrosurgical head 2 to clean and disinfect the used electrosurgical head 2. The used disinfectant will be discharged along the waste liquid hopper 12 to the waste liquid storage mechanism (the waste liquid hopper 12 is connected to the waste liquid storage mechanism through a conduit), thus achieving the effect of automatically cleaning and disinfecting the used electrosurgical head 2.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
