Description

Technical Field

[0001] This utility model relates to the field of endoscopy technology, specifically to a detachable multi-channel endoscopic surgical instrument. Background Technology

[0002] In modern medicine, endoscopic surgical instruments are widely used due to their minimally invasive nature and high efficiency. Endoscopic surgery, which involves inserting a thin endoscope into the body and using surgical instruments, significantly reduces surgical trauma, shortens recovery time, and improves surgical outcomes. However, existing endoscopic surgical instruments still have some limitations in practical applications, mainly in the following aspects:

[0003] Limited Functionality: Traditional endoscopic surgical instruments typically perform only a single function, such as observation, grasping, or cutting. During complex surgeries, surgeons often need to frequently change different instruments, which not only increases surgical time but may also increase surgical risks due to improper operation during instrument changes.

[0004] Inconvenient operation: Most existing endoscopic surgical instruments are designed with a fixed shape, lacking flexible clamping and control functions. During the operation, the surgeon needs to adjust the position and angle of the instruments through complex operations, which increases the difficulty and complexity of the operation, especially in scenarios requiring delicate operation.

[0005] Connection and disassembly are complex: The connection and disassembly of many endoscopic surgical instruments are cumbersome, requiring the use of threads or other fixing devices. This not only prolongs surgical preparation time but may also lead to weak connections or difficult disassembly, affecting the smooth progress of the surgery. Utility Model Content

[0030] like Figure 1-4As shown, a detachable multi-channel endoscopic surgical instrument includes a mounting base 1, on which a display screen 2 is provided. A first tube 3 is detachably provided at the bottom of the mounting base 1. The first tube 3 has a first channel 4 and a second channel 5. The first channel 4 has a first inlet 6 and a first outlet 7. The second channel 5 has a second inlet 8 and a second outlet 9. The first inlet 6 and the first outlet 7 form the first channel 4, and the second inlet 8 and the second outlet 9 form the second channel 5. The instrument also includes a second tube 10 for passing through the first channel 4. Both the first tube 3 and the second tube 10 are flexible tubes. A clamping assembly 11 is provided on one side of the second tube 10 at the first outlet 7. A lighting lamp 12 and a camera 13 are provided on the first tube 3 at the first outlet 7. The camera 13 is electrically connected to the display screen 2. The second channel 5 is used for the flow of liquid or gas.

[0031] In this embodiment, a detachable multi-channel endoscopic surgical instrument is designed for minimally invasive surgery. Its specific structure is as follows: The mounting base 1 is made of high-strength medical-grade plastic, possessing good biocompatibility and corrosion resistance. A high-resolution display screen 2 is mounted on the top of the mounting base 1 for real-time display of images of the surgical site. The display screen 2 is connected to a camera 13 via built-in circuitry. The camera 13 is installed at the first outlet 7b of the first conduit 3, enabling it to clearly capture details of the surgical area.

[0032] The first conduit 3 is a flexible tube made of medical-grade silicone, possessing excellent flexibility and anti-kink properties. Internally, the first conduit 3 has two independent channels: a first channel 4 and a second channel 5. The first channel 4 is used to insert the second conduit 10, which is also made of medical-grade silicone. Its outer diameter fits tightly with the inner diameter of the first channel 4, ensuring flexible operation and preventing loosening during surgery. The second channel 5 is used for the flow of liquids or gases, such as for rinsing wounds or inflating the surgical field during surgery.

[0033] At the first outlet 7 of the first tubing 3, a miniature illumination lamp 12 and a camera 13 are installed. The illumination lamp 12 uses high-brightness LED beads to provide a clear surgical field of view, while the camera 13 captures images through a built-in image sensor and transmits the signals to the display screen 2 on the mounting base 1. In addition, the second tubing 10 is equipped with a clamping assembly 11 on one side of the first outlet 7. This clamping assembly 11 consists of adjustable metal clips, which can flexibly fix the position of the second tubing 10 according to surgical needs, ensuring the stability of the surgical operation.

[0034] With this design, the detachable multi-channel endoscopic surgical instrument can not only meet the various operational needs in minimally invasive surgery, but also facilitate cleaning and disinfection through its detachable structure, thereby improving the reusability of the instrument and the safety of the surgery.

[0035] As a further technical solution, the second pipeline 10 and the side of the first outlet 7 have a direction adjustment part 14, which can be controlled by the display screen 2 to adjust the direction.

[0036] In this embodiment, a detachable multi-channel endoscopic surgical instrument further optimizes its operational flexibility and precision. Specifically, a direction adjustment section 14 is provided at the end of the second tube 10 (on the side near the first outlet 7), which enables the second tube 10 to bend and turn within a certain angle range. The direction adjustment section 14 consists of multiple movable joints, which are driven by built-in micro motors to achieve precise angle adjustment.

[0037] The operation and control of the direction adjustment unit 14 are achieved through the display screen 2 on the mounting base 1. The display screen 2 not only displays images of the surgical site but also integrates an operating interface. The surgeon can directly input commands on the display screen 2 via a touchscreen or operating buttons to control the bending angle and direction of the direction adjustment unit 14. The display screen 2 is connected to the micro-motor of the direction adjustment unit 14 through a built-in electronic control system, enabling real-time feedback of the adjustment status and ensuring the precision of the surgical operation.

[0038] For example, during minimally invasive surgery, if it is necessary to adjust the angle of the surgical instrument at the end of the second tubing 10 to better approach the surgical site, the surgeon can select the bending angle and direction of the direction adjustment unit 14 through the operating interface on the display screen 2. The display screen 2 will show the current status of the direction adjustment unit 14 in real time and adjust the drive parameters of the micro motor according to the surgeon's instructions, thereby achieving precise steering of the end of the second tubing 10. This design allows the surgical instrument to adapt more flexibly to complex surgical environments, improving the efficiency and safety of the surgery.

[0039] Through this further technical solution, the detachable multi-channel endoscopic surgical instrument not only has the convenience of being multi-channel and detachable, but also achieves flexible steering control of the end of the surgical instrument through the combination of the direction adjustment unit 14 and the display screen 2, further improving the accuracy and flexibility of the surgical operation.

[0040] As a further technical solution, the first pipeline 3 has a first connecting pipe 15, which is connected to the first channel 4. The first connecting pipe 15 has a thread on the side away from the first channel 4, and also includes a first mounting cap 16 with a thread on the first connecting pipe 15.

[0041] As a further technical solution, the first pipeline 3 has a second connecting pipe 17, which is connected to the second channel 5. The second connecting pipe 17 has a thread on the side away from the second channel 5, and also includes a second mounting cap 18 threaded on the second connecting pipe 17.

[0042] In this embodiment, a detachable multi-channel endoscopic surgical instrument further optimizes its connection structure and sealing performance. Specifically, a first connecting pipe 15 and a second connecting pipe 17 are respectively provided on the outer side of the first conduit 3. The first connecting pipe 15 is connected to the first channel 4 and is used to connect external instruments or equipment, such as a surgical instrument pushing device. The side of the first connecting pipe 15 away from the first channel 4 is provided with an external thread for connection with a first mounting cap 16. The inner side of the first mounting cap 16 is provided with an internal thread that matches the external thread of the first connecting pipe 15. By tightening the first mounting cap 16, the first connecting pipe 15 can be firmly fixed to the first conduit 3, while achieving a seal to prevent liquid or gas leakage.

[0043] Similarly, the second connecting pipe 17 is connected to the second channel 5 for connecting to external liquid or gas supply equipment, such as flushing fluid or an inflation device. The side of the second connecting pipe 17 away from the second channel 5 also has external threads for connection to the second mounting cap 18. The inner side of the second mounting cap 18 has internal threads that match the external threads of the second connecting pipe 17. By tightening the second mounting cap 18, the second connecting pipe 17 can be securely fixed to the first pipeline 3, achieving a seal.

[0044] This design allows for easy connection of the two channels of the first conduit 3 to external devices, while the threaded connection and mounting cap structure ensure a secure and airtight connection. In practical use, doctors can quickly connect or replace external devices according to surgical needs, improving the flexibility and practicality of surgical instruments.

[0045] As a further technical solution, the second pipeline 10 has a first connector 19 on the side away from the clamping assembly 11, and a second connector 20 is provided on the mounting base 1. The first connector 19 and the second connector 20 are electrically connected. After the first connector 19 and the second connector 20 are electrically connected, the display screen 2 can remotely control the movement of the clamping assembly 11.

[0046] In this embodiment, a detachable multi-channel endoscopic surgical instrument further optimizes its remote control function, improving the convenience and precision of surgical operations. Specifically, a first connector 19 is provided on the side of the second tube 10 away from the clamping assembly 11, while a second connector 20 is correspondingly provided on the mounting base 1. These two connectors transmit signals through an electrical connection.

[0047] Once the first connector 19 and the second connector 20 are electrically connected, the display screen 2 can remotely control the movement of the clamping assembly 11 through its built-in control system. Specifically, the display screen 2 integrates an operating interface, allowing doctors to input commands via the touchscreen or operating buttons. These commands are transmitted to the control unit of the clamping assembly 11 via electrical connection. The clamping assembly 11 executes corresponding actions based on the received commands, such as clamping or releasing the second tubing 10, thereby achieving precise control of the second tubing 10.

[0048] As a further technical solution, the mounting base 1 is also provided with a trigger 21, which is electrically connected to the clamping assembly 11. The clamping assembly 11 can be controlled to move by moving the trigger 21.

[0049] In this embodiment, a detachable multi-channel endoscopic surgical instrument further optimizes its operation, making it more in line with the actual operating habits of surgeons and improving the convenience and precision of the surgery. A trigger 21 is provided on the mounting base 1, which is electrically connected to the clamping assembly 11. By pulling the trigger 21, the surgeon can directly control the movement of the clamping assembly 11. This design is similar to the operation of common surgical instruments; the surgeon can easily operate the clamping assembly 11 through natural finger movements without relying on complex electronic devices or a display screen 2 for control.

[0050] As a further technical solution, an opening and closing component 22 is provided in the second channel 5 on one side of the second outlet 9. The opening and closing component 22 is used to open or close the second channel 5.

[0051] As a further technical solution, the opening and closing component 22 includes two baffles 23 disposed in the first pipe 3 within the second channel 5, the two baffles 23 forming a flow gap 24, and a retaining ball 25 movably disposed in the flow gap 24 within the second channel 5. After the retaining ball 25 moves within the second channel 5, it is used to open or close the flow gap 24. It also includes an elastic member 26 with one end disposed on the first pipe 3 within the second channel 5 and the other end disposed on the retaining ball 25. The elastic member 26 is used to provide the force for the retaining ball 25 to abut against the baffles 23.

[0052] In this embodiment, a detachable multi-channel endoscopic surgical instrument further optimizes the control function of its second channel 5 by setting a unique opening and closing component 22 in the second channel 5, thereby achieving flexible control of the channel.

[0053] Specifically, an opening / closing assembly 22 is provided on the side of the second channel 5 near the second outlet 9. This assembly 22 includes two baffles 23 symmetrically arranged on the inner wall of the second channel 5, forming a flow gap 24. When the baffle ball 25 is located at the flow gap 24, it completely blocks the gap, thus closing the second channel 5. When the baffle ball 25 moves to another position, the flow gap 24 opens, allowing liquid or gas to flow through the second channel 5.

[0054] To enable the movement and positioning of the retaining ball 25, the opening and closing assembly 22 also includes an elastic element 26. One end of the elastic element 26 is fixed to the inner wall of the first pipe 3, and the other end is connected to the retaining ball 25. The function of the elastic element 26 is to provide a continuous force so that the retaining ball 25 can tightly abut against the baffle 23, thereby ensuring the sealing of the second channel 5. When it is necessary to open the second channel 5, water or air is continuously injected into the second channel 5, so that the pressure inside the second channel 5 can overcome the resistance of the elastic element 26 and move, thereby opening the flow gap 24; when it is necessary to close the second channel 5, when flushing or air inflation is not required, the restoring force of the elastic element 26 will cause the retaining ball 25 to abut against the baffle 23 again, closing the flow gap 24.

[0055] As a further technical solution, the clamping assembly 11 includes a clamping seat 27 disposed at the end of the second pipe 10 and two grippers 28 oscillatingly disposed on the clamping seat 27. After the grippers 28 oscillate on the clamping seat 27, they are used to clamp the item.

[0056] This technical solution further optimizes the functionality and ease of operation of the detachable multi-channel endoscopic surgical instrument by incorporating an opening / closing component 22 at the end of the second conduit 10. The specific technical effects are as follows:

[0057] The clamping seat 27 and swing jaw 28 in the clamping assembly 11 are designed to flexibly clamp various surgical instruments or auxiliary tools at the end of the second tubing 10. This design allows surgeons to quickly change or adjust tools as needed during surgery without frequent disassembly and reassembly of endoscopic instruments, thus significantly improving the flexibility and efficiency of surgical procedures.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
