Description

Technical Field

[0001] The present invention relates to the field of laser surgical equipment, in particular to a laser fiber manipulator. Background Art

[0002] Due to its high efficiency, precision and good cutting and hemostatic effects, laser can not only be used to remove surface skin and tumors, but has also been gradually used in laparoscopic organ resection surgery in recent years. As a new technology, it has a tendency to replace traditional scalpels. Moreover, with the development and application of various laser optical fibers of different wavelengths, the scope of application of laser medicine in clinical practice will become wider and wider in the future.

[0003] However, there is currently no dedicated laser fiber operating instrument for laparoscopic surgery. Therefore, when some physicians begin to try to use laser fiber for surgical treatment during laparoscopic surgery, they can only use some temporary operating rods to operate the laser fiber, which is very inconvenient to use and also exposes the following problems:

[0004] 1. Due to the high energy of the laser fiber, continuous water cooling is required during the operation to reduce the formation of eschar on the wound surface;

[0005] 2. Based on the above, laser fiber will also produce a large amount of smoke when removing organs or human tissues, making the operating field of view unclear and requiring timely expulsion; however, since laparoscopic surgery establishes pneumoperitoneum pressure, if there is air leakage or the suction position is not accurate or timely during suction, while ensuring the suction purpose, excess gas will be over-absorbed, resulting in a sharp lack and instability of pneumoperitoneum pressure, affecting the surgical operating space and interfering with the precise operation of the surgery.

[0006] 3. Based on the above, in order to achieve suction and flushing, two additional incisions had to be made on the patient's skin, and two laparoscopic operating punctures were added, which increased the cost of the operation. In addition, during the clinical operation, at least one additional assistant was required to assist in continuous water injection and cooling during the operation, and to use a suction device to aspirate blood, water and smoke.

[0007] Therefore, in summary, it can be seen that not only the comfort and efficiency of surgical operation are greatly reduced, but also the number of skin incisions and the use of surgical consumables are increased; it seriously restricts the widespread application of laser surgery.

[0008] In view of the above problems, a laser fiber manipulator is designed. Summary of the Invention

[0063] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0064] In a specific embodiment, a laser fiber manipulator is provided, comprising:

[0065] A first guide tube 10, a second guide tube 11 and a third guide tube 12 can be introduced into the abdominal cavity; and a first tube sleeve 1 is used to install and fix the three guide tubes. The first tube sleeve 1 here is equivalent to a mounting seat, and the three guide tubes are installed at its front end, and a front-end drainage channel is constructed between the three guide tubes, namely, the third channel P3, the second channel P2 and the first channel P1.

[0066] In addition, the operator also includes a second sleeve 2 and a third sleeve 4 installed at the rear end of the first sleeve 1, forming a rear end drainage cavity therebetween, namely the first rear cavity C1 and the second rear cavity C2, and the two cavities are respectively connected to corresponding control valves to control the flushing volume and the suction volume.

[0067] In order to realize the flushing and suction functions, the front drainage channel and the rear drainage cavity are connected.

[0068] A fourth sleeve 5 and a fifth sleeve 6 are also provided at the rear end of the manipulator. The fifth sleeve 6 is screwed onto the rear end of the third sleeve 4, and the fourth sleeve 5 is screwed or plugged into the rear end of the fifth sleeve 6. The fourth sleeve 5 is primarily used to install or secure the rear end of the optical fiber a, ensuring that the front end of the optical fiber a can be positioned along the inner side of the guide tube and that the optical fiber a is stably positioned. Furthermore, it acts as the handle of the manipulator during operation, facilitating surgical procedures. The fifth sleeve 6 is primarily used to seal the connection at the rear end of the optical fiber a, preventing liquid from leaking from the end of the fourth sleeve 5. A sealing gasket 14 is provided at the front end of the fifth sleeve 6, and a waterproof cap 15 is provided at the rear end of the fifth sleeve 6. Both are made of elastic rubber material, allowing the optical fiber a to pass through them in a sealed manner. It can be seen that the sealing gasket 14 and the waterproof cap 15 provide a double-layer seal, further improving the sealing effect. Furthermore, an elastic tail cap 16 is provided at the end of the fourth sleeve 5 to support the rear end of the optical fiber a and prevent it from being significantly bent and damaged.

[0069] To achieve the installation and arrangement of optical fiber a, in this embodiment, optical fiber a is arranged on the axis of the manipulator and extends from the front end to the rear end. The front end is used for cutting, and the rear end is connected to the laser generator.

[0070] In summary, the specific structure and connection form of this embodiment are as follows:

[0071] The first sleeve 1 is provided with a front channel 1.4 for passing the optical fiber a through its axis. After the optical fiber a is passed through, a gap is usually left between the front channel 1.4 for the passage of flushing liquid. Therefore, in this embodiment, since the optical fiber a is closest to the front channel 1.4, the front channel 1.4 is mainly used to release flushing liquid to clean and cool the cut area.

[0072] In order to allow the flushing liquid to enter, a first interface 1.6 connected to the front channel 1.4 is opened on the side wall of the first pipe sleeve 1, and a second rotary valve 9 is installed on the first interface 1.6 to control the on-off and flushing flow of the flushing liquid. The second rotary valve 9 is usually a ball valve. In this embodiment, the second rotary valve 9 can achieve the normal opening and closing effects of the corresponding channel.

[0073] In this embodiment, the first guide tube 10, the second guide tube 11 and the third guide tube 12 are coaxially installed at the front end of the first tube sleeve 1, and are arranged in sequence from the outside to the inside; wherein, the third channel P3 is formed between the first guide tube 10 and the second guide tube 11, the second channel P2 is formed between the second guide tube 11 and the third guide tube 12, the inner side of the third guide tube 12 is the first channel P1, and the first channel P1 is connected to the front channel 1.4 to guide the flushing liquid to the cutting tissue.

[0074] As a preferred embodiment of the above-mentioned embodiment, in order to facilitate the installation stability and sealed connection of each guide tube, the front end of the first pipe sleeve 1 is respectively provided with a first annular groove 1.1, a first annular groove 1.2, and a third annular groove 1.3, and they are arranged in sequence from the outside to the inside along the radial direction of the first pipe sleeve 1. The first guide tube 10, the second guide tube 11 and the third guide tube 12 are installed in the corresponding annular grooves in the order from the outside to the inside. Therefore, the grooves can be used to limit and fix the ends of the guide tubes. Specifically, they should be threadedly connected or tightly fitted with the grooves.

[0075] In this embodiment, the third channel P3 is mainly used for smoke suction, and the second channel P2 is mainly used for flushing liquid suction.

[0076] To achieve back-end traffic diversion, the specific connection structure of the operator back-end is as follows:

[0077] A second pipe sleeve 2 is threadedly connected to the rear end of the first pipe sleeve 1. This threaded connection is for flow diversion and is typically a sealed connection. Furthermore, to divert flow outward, a second port 2.1 is also provided on the sidewall of the second pipe sleeve 2. This port 2.1 is fitted with a first rotary valve 8, which can be a ball valve, to achieve either a normally open or normally closed state.

[0078] In order to construct the rear end drainage cavity, a third pipe sleeve 4 is also included, and an extension pipe 4.1 is provided at its front end. The main function of the extension pipe 4.1 is to form a sleeve structure with the second pipe sleeve 2.

[0079] Specifically, the front end of the extension tube 4.1 is sealed and connected to the first tube sleeve 1, while the rear end of the extension tube 4.1 is threadedly connected to the rear end of the second tube sleeve 2. This threaded connection is also a sealed connection. This creates a first rear cavity C1 for fluid diversion between the extension tube 4.1 and the second tube sleeve 2, and a second rear cavity C2 is formed inside the extension tube 4.1. These two cavities form separate, non-connected drainage channels for easier control.

[0080] As a preferred embodiment of the above-mentioned embodiment, in order to achieve the positioning of the extension pipe 4.1 and the sealed connection with the rear end of the first pipe sleeve 1, a fourth annular groove 1.5 is opened at the rear end of the first pipe sleeve 1, and an elastic rubber ring is provided at the bottom of the groove. After installation, the extension pipe 4.1 is inserted into the fourth annular groove 1.5 and pressed against the elastic rubber ring to achieve end sealing.

[0081] As a preferred embodiment of the present invention, as can be seen from the above, the rear end of the first pipe sleeve 1 is threadedly connected to the second pipe sleeve 2, and the rear end of the extension pipe 4.1 is threadedly connected to the rear end of the second pipe sleeve 2. Since the first pipe sleeve 1 is threaded, when installing, in order to ensure that the installation position of the first rotary valve 8 and the third interface 4.4 are simultaneously threaded to meet the sealing requirements, an intermediate sleeve 3 is used to prevent the second pipe sleeve 2 and the extension pipe 4.1 from rotating synchronously when screwing. The specific structure is as follows:

[0082] A tapered, thin-walled snap ring 4.11 is installed around the perimeter of the extension pipe 4.1, with several open grooves defined within its annular wall. Due to the compression and deformation of the open grooves by the thin-walled snap ring 4.11, an intermediate sleeve 3 is sealed from the smaller end of the snap ring 4.11 to the rear end of the extension pipe 4.1. This seal is typically achieved by a sealing ring within the intermediate sleeve 3, which provides a motion-tight connection with the extension pipe 4.1. A mating slot 3.1 is provided within the intermediate sleeve 3, threaded on its interior, and threadedly engaged with the second sleeve 2. This prevents the extension pipe 4.1 from rotating, instead enabling its movement through the rotation of the intermediate sleeve 3, thereby improving ease of use.

[0083] The front and rear end drainage connection mode is as follows: the second channel P2 is connected to the second rear cavity C2, and the third channel P3 is connected to the first rear cavity C1.

[0084] In addition, according to the above, since the front channel 1.4 is mainly a flushing channel, in order to prevent the flushing liquid from entering the second rear cavity C2, the connection between the front channel 1.4 and the second rear cavity C2 is sealed by a sealing sleeve 13; in this embodiment, in order to allow the optical fiber a to pass through in a sealed manner, the sealing sleeve 13 is usually made of rubber material, and the optical fiber a can slide through the sealing sleeve 13 in a sealed manner. Specifically, a plurality of sealing rings can be provided on the inner side of the hole matching the optical fiber a, and the sealing ring is connected to the outer wall of the optical fiber a. It belongs to the existing active sealing form and is sealed in the valve stem, which will not be repeated here.

[0085] Similarly, to allow the second rear cavity C2 to flow outward, a third port 4.4 is provided on the third sleeve 4. This port is equipped with a pressure valve. This pressure valve is typically a valve that opens and closes by pressing, and is a point-controlled valve. During use, the valve can be opened and closed by pressing a finger, achieving intermittent suction and improving ease of use.

[0086] In addition, the second channel P2 can also be used as a flushing channel. When in use, the flushing liquid can be discharged from the through hole on the peripheral wall of the front end of the third guide tube 12 for auxiliary flushing, and combined with the control of the press valve, intermittent cleaning can be achieved, thereby improving ease of use.

[0087] As a preferred embodiment, in order to realize the selection of the suction or flushing function of the second channel P2, the third interface 4.4 includes a first branch port 4.41 and a second branch port 4.42, which are respectively connected to the second rear cavity C2; in order to realize the intermittent control of the suction or flushing of the second channel P2, two press valves are used for control, namely the first press valve 4.2 and the second press valve 4.3. The first press valve 4.2 controls the opening and closing of the first branch port 4.41, and the second press valve 4.3 controls the opening and closing of the second branch port 4.42. Therefore, when in use, different flushing pumps or aspirators can be connected to the first branch port 4.41 and the second branch port 4.42 accordingly.

[0088] During clinical use, each valve is first connected to external equipment, specifically the corresponding abdominal pressure suction device and water supply pump. Optical fiber a is then inserted from the rear end of the manipulator and extended to the front end for tissue cutting. During use, the first, second, and third guide tubes 10, 11, and 12 are introduced into the abdominal cavity through a channel established in the abdominal cavity. Under visual guidance of the endoscope, the cut end of optical fiber a is brought to the affected area and cut. Simultaneously, the second rotary valve 9 is opened to supply flushing fluid, which is introduced into the front end of optical fiber a through the first channel P1 for flushing and cooling. Because cutting produces smoke, the first rotary valve 8 can be opened to continuously generate a slight negative pressure in the third channel P3. The smoke can then be aspirated while maintaining stable pneumoperitoneum pressure. Additionally, when aspiration of flushing fluid is required, the press valve can be controlled to allow the flushing fluid to enter through the second channel P2 and be collected.

[0089] Therefore, it can be seen that cutting, flushing, aspiration and smoking are all arranged on the same manipulator, and the surgeon can perform the above operations with one hand. By installing the optical fiber a on the pen-shaped manipulator, it is easy to take and control the optical fiber.

[0090] In this case, the third channel P3 and the second channel P2 usually have smaller channel cross-sections, which can avoid a rapid decrease in pneumoperitoneum pressure during suction.

[0091] In addition, it can be seen that since the flushing end and the suction end are both arranged around the cutting point of the optical fiber a, flushing and suction can be achieved quickly and efficiently, especially when smoking. Accurate and rapid suction can be performed when the smoke is not completely diffused, avoiding over-suction and missed suction, ensuring the smooth change of the pneumoperitoneum pressure, improving the visual effect, and improving the efficiency and safety of the operation.

[0092] In addition, the cutting, flushing and suction functions are integrated into one device, which can reduce the opening of the patient's abdomen and the use of medical tools, thereby reducing patient damage and reducing medical costs.

[0093] In summary, during surgery, to further enhance the surgical field of view and facilitate observation of the position of optical fiber a, the front end of third guide tube 12 is positioned to protrude beyond the front end of second guide tube 11, and the front end of second guide tube 11 is positioned to protrude beyond the front end of first guide tube 10. This creates a stepped front end of the manipulator. This reduces obstruction of optical fiber a by first and second guide tubes 10, 11, improving cutting accuracy and further enhancing surgical safety.

[0094] To further improve the efficiency and range of suction and flushing, through holes are opened on the front end peripheral wall of the first guide tube 10 and the front end peripheral wall of the third guide tube 12, wherein the through hole on the front end peripheral wall of the third guide tube 12 extends to the inside of the second guide tube 11.

[0095] In practice, since the first tube 10 serves as the primary inhalation channel, the through-holes on the front sidewall allow diffused smoke to enter, improving suction efficiency. Furthermore, since the front end of the third tube 12 is the most protruding, suction can be conducted through the through-holes on the front peripheral wall of the third tube 12 during suction in the second passage P2, improving suction efficiency and, to a certain extent, preventing larger blood clots from entering the second passage P2.

[0096] In summary, during the surgical operation, in order to realize the telescopic control of the optical fiber a and adapt to the cutting at different positions, a mechanism for controlling the movement of the optical fiber a is provided at the fourth sleeve 5, as follows:

[0097] A mounting opening 5.1 is defined on one side of the fourth sleeve 5. A button 7 is mounted within this opening, capable of reciprocating along the axis of the fourth sleeve 5. One end of the button 7 is positioned outside the opening 5.1, while the other end is positioned inside. This end is provided with a clamping opening 7.1, which can grip the optical fiber A. During use, pushing the button 7 allows the front end of the optical fiber A to be extended or retracted. Similarly, to achieve a sliding connection between the fourth sleeve 5 and the optical fiber A, a sealing gasket 14 is mounted at the front end of the fourth sleeve 5. The optical fiber A is sealed and slidably inserted within the sealing gasket 14.

[0098] On this basis, to further position the optical fiber a and prevent it from moving during cutting, a limit plate 5.2 is provided inside the mounting opening 5.1, forming a slot with the edge of the mounting opening 5.1. In addition, a wing plate 7.2 is provided on the peripheral wall of the button 7 and is inserted into the slot. A spring 5.3 is provided inside the slot to abut against the wing plate 7.2 and enable the button 7 to rebound when pressed.

[0099] In addition, a plurality of grooves 5.4 are arranged in an array on the inner edge of the mounting opening 5.1. Meanwhile, a protrusion 7.3 is formed on the wing plate 7.2. The protrusion 7.3 fits within the groove 5.4 to position the button 7. During use, pressing the button 7 disengages the protrusion 7.3 from the groove 5.4, allowing the button 7 to slide back and forth within the mounting opening 5.1, thereby driving the optical fiber A to extend and retract. Once the cleaved end of the optical fiber A is positioned, the button 7 is released, and the elastic force of the spring 5.3 causes the protrusion 7.3 to cooperate with the groove 5.4 to limit the button 7, thereby positioning the optical fiber A.

[0100] In summary, in order to better facilitate the clamping of the optical fiber a, a notch 7.4 is provided on the contour edge of the clamp 7.1, which passes through the clamp 7.1. The notch 7.4 makes the clamp 7.1 elastic. During installation, the optical fiber a can be smoothly inserted into the clamp 7.1 by prying open the notch 7.4. After the clamping position is determined, the notch 7.4 is released so that the clamp 7.1 can clamp the optical fiber a. Therefore, the installation convenience can be improved.

[0101] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
