Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to a handle for an electronic thoracoscope and an electronic thoracoscope. Background Technology

[0002] In the field of medical devices, electronic thoracoscopes and laparoscopes are increasingly widely used. Semi-disposable electronic thoracoscopes and laparoscopes combine the advantages of single use and reusability. For example, the electronic thoracoscope and laparoscope with replaceable insertion part disclosed in patent CN116250791A has a single-use insertion part (i.e., the endoscope body) and a reusable handle part that does not require cleaning and sterilization, effectively avoiding cross-infection, extending the life of the handle, and shortening the reprocessing cycle.

[0003] However, compared to traditional optical endoscopes, these semi-displaceable electronic thoracoscopes still have significant shortcomings. Traditional optical endoscopes connect to a handpiece via an adapter, using optical lens groups to transmit images and allowing for free rotation, facilitating flexible adjustment of the observation angle during laparoscopic surgery. Existing electronic endoscopes, on the other hand, rely on FPCs (flexible printed circuit boards) and cables to transmit signals, preventing free rotation and requiring wrist rotation to adjust the observation angle. However, the human wrist has a limited range of motion, and maintaining a large angle of rotation for extended periods can easily cause soreness, severely impacting the precision and continuity of surgical procedures.

[0004] Furthermore, conventional electronic endoscopes, as reusable instruments, require frequent cleaning and sterilization processes, which places extremely high demands on the product's sealing system, making it difficult to incorporate a rotatable structure. Although the handle of a semi-disposable electronic endoscope only requires cleaning, making it possible to incorporate a rotatable structure, there are currently no mature rotatable semi-disposable electronic thoracoscopes or laparoscopes. Therefore, there is an urgent need to develop a rotatable semi-disposable electronic thoracoscope or laparoscope that can solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a handle and an electronic thoracoscope / laparoscopy system, aiming to ensure the precision of surgical procedures.

[0006] The technical solution adopted by this utility model is as follows: a handle for an electronic thoracoscope and laparoscopy, comprising a housing, an interface, a signal board, a main board, and a rotating assembly; a locking device is provided on the front end of the housing, and the locking device is hollow inside; the interface, signal board, and main board are all located inside the housing; the interface is located at the end of the locking device; the signal board is fixed on the interface, and the signal board and the main board are electrically connected via an FPC, and are rigidly connected; the rotating assembly includes an angle knob, and a gear and a connecting rod located inside the housing; the angle knob is located outside the housing, and is sleeved on the outer circumference of the gear, and the two rotate synchronously; the front end of the gear is fixedly connected to the main board via the connecting rod.

[0007] According to the above scheme, a support is also provided inside the housing; the gear is rotatably connected to the support.

[0008] According to the above scheme, the signal board and the motherboard are rigidly connected by axially arranged connecting columns.

[0009] According to the above scheme, the motherboard is provided with an internal button board for program and button control; the outer wall of the housing is provided with buttons that correspond to and are connected to the internal button board.

[0010] According to the above scheme, the handle also includes an extension section, which is connected to the end of the housing through a tapered section; the signal transmission line passes through the support and then enters the tapered section and the extension section in sequence.

[0011] According to the above scheme, the inner diameter of the extension section is smaller than the inner diameter of the shell.

[0012] According to the above scheme, the axial directions of the gear and the angle knob are both consistent with the axial direction of the housing.

[0013] According to the above scheme, the support is provided with wire holes for the signal transmission lines of the motherboard to pass through.

[0014] This utility model also discloses a rotatable electronic thoracoscope and laparoscope, including an endoscope body and a handle as described above; the end of the endoscope body is inserted into the locking device of the handle, and the insertion part of the end of the endoscope body is connected to the interface of the handle; the locking device is covered with a handle cover.

[0015] According to the above scheme, the scope is a disposable scope.

[0016] The beneficial effects of this utility model are as follows: 1. The handle of this utility model is equipped with a rotating component consisting of an angle knob, gears, and connecting rods. During surgery, the doctor only needs to use their thumb to easily turn the angle knob to quickly and flexibly rotate the endoscope and adjust the observation angle. This method of adjusting the lens angle by turning the angle knob completely eliminates the limitation of the human wrist rotation angle compared with the existing traditional wrist rotation operation method, improves the convenience of surgical operation, and enables doctors to obtain surgical fields of view from different angles more conveniently and efficiently, ensuring the accuracy of surgical operation and meeting the diverse observation needs in complex surgical scenarios.

[0017] 2. The design of the handle described in this utility model avoids doctors from maintaining an unnatural wrist posture for a long time, significantly reduces wrist fatigue, effectively reduces the fatigue intensity of surgical operations, helps doctors maintain a good physical condition and concentration during surgery, thereby improving the accuracy and efficiency of surgery, and providing a strong guarantee for the smooth progress of surgery.

[0018] 3. The present invention has a reasonable structural design and a compact layout of all components; it makes full use of the characteristic that the semi-disposable electronic mirror handle only needs to be cleaned and does not require cleaning and sterilization, and the rotating structure is reasonably designed to avoid the stringent requirements on the sealing system due to frequent cleaning and sterilization, further simplifying the structural design and production process, so that the product has a significant cost advantage.

[0030] A handle for an electronic thoracoscope and laparoscopy includes a housing 14, an interface 2, a signal board 3, a main board 6, and a rotating assembly. A locking device 1 is provided on the front exterior of the housing 14. The locking device 1 is hollow inside and is used for the insertion of the scope 16 of the electronic thoracic and laparoscopic endoscope. The interface 2, signal board 3, and main board 6 are all located inside the housing 14, and all three can rotate inside the housing 14. The interface 2 is located at the end of the locking device 1 and is connected to the end of the mirror body 16 inserted through the locking device 1. The signal board 3 is fixed on the interface 2, and the signal board 3 and the main board 6 are electrically connected through the FPC (Flexible Printed Circuit) 4, and the signal board 3 and the main board 6 are rigidly connected. The rotating assembly includes an angle knob 13, a gear 9 and a connecting rod 8 disposed inside the housing 14; the angle knob 13 is disposed outside the housing 14 and is sleeved on the outer circumferential surface of the gear 9, and the two rotate synchronously; the front end of the gear 9 is fixedly connected to the main board 6 through the connecting rod 8. The signal transmission line 11, which is connected to the motherboard 6, passes through the gear 9 and is connected to the cable connector at the end of the handle 19 (this is prior art and is not shown in the attached figure).

[0031] In this invention, the axial directions of both the gear 9 and the angle knob 13 are aligned with the axial direction of the housing 14. When medical personnel manually turn the angle knob 13, the gear 9 inside the housing 14 rotates synchronously, driving the main board 6 to rotate via the connecting rod 8. The signal board 3 and interface 2 connected to the main board 6 then rotate, causing the endoscope 16 connected to the interface 2 to rotate, thus adjusting the angle of the endoscope 16. The angle knob 13 is connected to the gear teeth of the gear 9 by gluing or welding, and the two can be considered as a single component.

[0032] In this invention, the connecting rod 8 is made of high-strength plastic or metal material and is used for the rigid connection between the gear 9 and the main board 6.

[0033] Preferably, a support 10 is also provided inside the housing 14; the gear 9 is rotatably connected to the support 10.

[0034] In this invention, the support 10 is used to support the gear 9, and the gear 9 can rotate relative to the support 10.

[0035] Preferably, the support 10 has a wire hole for the signal transmission line 11 to pass through.

[0036] In this invention, the signal transmission line 11 is a flexible cable that can achieve large-angle twisting (twist angle range is -180° to 180°); even when the motherboard 6 rotates 180°, normal signal transmission can still be guaranteed.

[0037] Preferably, the signal board 3 and the main board 6 are rigidly connected by an axially arranged connecting column 5.

[0038] In this invention, the connecting post 5 is made of high-strength plastic or metal material and is used for rigid connection between the signal board 3 and the motherboard 6.

[0039] Preferably, the motherboard 6 is provided with an internal button board 7 for program and button control; the outer wall of the housing 14 is provided with buttons 12 that correspond to and are connected to the internal button board 7.

[0040] In this invention, button 12 is connected to the internal button board 7 for operating handle 19. The button board 7 is a circuit board that controls the button functions. By controlling the switch of the button board 7, the button board 7 generates electrical signals and transmits them to the main board to form instructions; this is a mature technology already existing in the industry, and will not be described in detail here.

[0041] Preferably, the handle 19 further includes an extension section 15, which is connected to the end of the housing 14 via a tapered section; the signal transmission line 11 passes through the support 10 and enters the tapered section and the extension section 15 in sequence, and is connected to a cable connector located at the end of the extension section 15.

[0042] In this invention, the inner diameter of the extension section 15 is smaller than the inner diameter of the shell 14.

[0043] In this utility model, the locking device 1 adopts an existing structure, as described in patent CN116047743A; the locking device 1 is not the focus of this application and will not be described in detail here.

[0044] In this invention, the signal board 3 and the main board 6 are connected via an FPC4, which is flexible and can be used for signal transmission. The images and signals acquired by the endoscope 16 of the electronic thoracic and laparoscopic system are transmitted to the signal board 3 through the interface 2, then to the main board 6 via the FPC4, and finally to the external main device via the signal transmission line 11 through the cable connector at the end of the handle 19.

[0045] An electronic thoracoscope, specifically a rotatable electronic thoracoscope, includes a body 16 and a handle 19 as described above. The end of the body 16 is inserted into a locking device 1 of the handle 19, and the insertion part 20 at the end of the body 16 is connected to the interface 2 of the handle 19. A handle cover 18 is provided over the locking device 1. The handle cover 18 is flared. The body 16 is a disposable body, with a lens 17 at the front end and the insertion part 20 connected to the interface 2 at the rear end.

[0046] In this utility model, the structure and function of the mirror body 16, signal board 3, interface 2, main board 6, internal button board 7 and button 12 are all existing mature technologies, and will not be described in detail here.

[0047] The working principle of this utility model is as follows: In use, first insert the endoscope 16 into the locking device 1 of the handle 19, connecting the endoscope 16 to the interface 2 inside the housing 14, and then lock it in place using the locking device 1. Then, cover the handle with the cover 18 to complete assembly. Turn on the power and set the device parameters using the button 12 on the housing 14 connected to the internal button panel 7, then proceed with the surgery. During the surgery, when the doctor needs to adjust the observation angle, they hold the handle 19 and turn the angle knob 13 with their thumb. The angle knob 13 drives the gear 9 to rotate synchronously. The gear 9 drives the main board 6 to rotate via the rigid connecting rod 8. The main board 6 then drives the signal board 3 and interface 2 to rotate via the connecting post 5, thereby driving the endoscope 16 to rotate, causing the lens 17 at the front of the endoscope 16 to rotate synchronously, thus adjusting the observation angle. Because the support 10 remains fixed and the signal transmission line 11 is flexible, even when the main board 6 rotates 180 degrees, normal signal transmission can still be ensured, guaranteeing stable transmission of images and signals during the surgery.

[0048] Example 1 like Figure 1 and Figure 2 The illustrated handle for an electronic thoracoscope / laparoscopy includes a locking device 1 and a housing 14. The locking device 1, which is hollow, is located at the front end of the housing 14 and is used to securely lock the inserted endoscope body 16. Inside the housing 14, the locking device 1 has an interface 2 at its end for connecting to the inserted endoscope body 16. The rear end of the interface 2 is connected to a signal board 3, which is connected to a main board 6 via an FPC 4 and a connecting post 5. The FPC 4 is flexible and used for signal transmission. The connecting post 5 is made of high-strength plastic or metal and is used for rigid connection. The main board 6 has an internal button panel 7 for program and button control. The end of the main board 6 has a signal transmission line 11, which is connected to a gear 9 via the connecting post 5. The connecting post 5 is also made of high-strength plastic or metal. The rear end of the gear 9 is a support 10, with a wire hole between them for the signal transmission line 11 to pass through. The signal transmission line 11 is a flexible cable with a large twist angle and extends to the cable connector at the end of the handle 19. Outside the housing 14, the surface of the housing 14 of the handle 19 has buttons and an angle knob 13. The buttons are connected to the internal button plate 7 and are used to operate the handle 19. The angle knob 13 is connected to the gear 9. When holding the handle 19, the angle knob 13 can be turned with the thumb. The angle is limited to 180° clockwise and 180° counterclockwise. At this time, the gear 9 rotates synchronously and drives the main board 6, signal board 3 and interface 2 to rotate through the rigid connecting rod 8 and connecting column 5.

[0049] Example 2 like Figure 3The rotatable electronic thoracoscope and laparoscope includes a body 16 and a handle 19 as described above. The end of the body 16 is inserted into a locking device 1 of the handle 19 and connected to an interface 2 of the handle 19. A handle cover 18 is fitted over the locking device 1. The handle cover 18 is trumpet-shaped. Figure 5 As shown. Figure 4 As shown, the mirror body 16 is a disposable mirror body 16, with a lens 17 at the front end and a plug-in part 20 connected to the interface 2 at the rear end. When the interface 2 of the handle 19 is rotated, the mirror body 16 connected to the interface 2 rotates accordingly, and the lens 17 at the front end of the mirror body 16 rotates synchronously, thereby adjusting the observation angle.
