Abstract

A medical forceps-type laser knife, comprising a handle body (1), wherein a pressing mechanism (3) is arranged in the handle body (1). Laser is guided into a laser optical fiber (5) by means of a connector (6) and is transmitted to a laser knife body (10), which converts the transmitted laser energy into heat energy for cutting, vaporization, hemostasis, and ablation of tissue. A clamping trigger body (301) is pulled, and then a closure clip (9) is closed towards the laser knife body (10) to clamp tissue. When a tissue clamping function is not needed, a U-shaped rod (201) is rotated, so that a magnet positive pole (203) and a magnet negative pole (204) are magnetically attracted together to fix the U-shaped rod (201), and the clamping trigger body (301) is supported and limited, thereby avoiding accidental clamping of tissue caused by accidentally pressing the clamping trigger body (301), achieving a protective effect.

Description

A medical clamp-type laser knife

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 29, 2023, with application number 202311093991.8 and invention name “A Medical Clamp-Type Laser Knife”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of surgical laser instruments, and in particular to a medical clamp-type laser knife. Background Art

[0003] Laparoscopic surgery is a newly developed minimally invasive procedure and an inevitable trend in the future of surgical treatment. Currently, conventional surgical instruments used in minimally invasive laparoscopic surgery can cause significant tissue damage during treatment. Cutting instruments, hemostatic instruments, and clamping instruments must be frequently replaced to remove tissue and stop bleeding. This is particularly true during tumor resection, where cancer cells migrate through the bloodstream to surrounding tissues, causing metastasis and potentially exposing the patient to the risk of reoperation or even life-threatening complications. Laparoscopic procedures typically last up to two hours, requiring prolonged anesthesia, severely impacting postoperative recovery. Furthermore, prolonged operating times can cause stress and fatigue for surgeons, potentially compromising treatment effectiveness. Instruments that can simultaneously perform cutting, hemostatic, and clamping functions are highly valuable and hold promise for replacing traditional surgical instruments, reducing bleeding and shortening operative time. This promises to benefit both patients and surgeons, ultimately improving national healthcare standards.

[0004] In the existing technology, medical forceps-type laser knives can simultaneously take into account the functions of cutting, hemostasis and clamping tissue during surgery, without the doctor needing to frequently change surgical instruments. The function of clamping tissue needs to be achieved by pressing the closed splint. However, when using the medical forceps-type laser knife, the handle needs to be held by hand, and the closed splint is close to the handle. When taking the handle, it is easy to press the closed splint accidentally, thereby clamping the tissue when the clamping function is not needed, affecting the surgical operation.

[0005] Therefore, we propose a medical clamp-type laser knife to solve the above-mentioned problems. Technical issues

[0006] The purpose of the present application is to provide a medical clamp-type laser knife to solve the problem that the medical clamp-type laser knife proposed in the above background technology can simultaneously take into account the functions of cutting, hemostasis and clamping tissue during surgery, wherein the function of clamping tissue needs to be achieved by pressing the closed splint. However, when using the medical clamp-type laser knife, the handle needs to be held by hand, and the closed splint is close to the handle. When taking the handle, it is easy to press the closed splint accidentally, thereby clamping the tissue when the clamping function is not needed, affecting the surgical operation.

Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] Please refer to Figures 1 to 8. The present application provides a technical solution: a medical clamp-type laser knife, as shown in Figure 1. The medical clamp-type laser knife of this embodiment includes: a handle body 1, a pressing mechanism 3 is provided inside the handle body 1, a metal direction rotator 8 is provided on the outer surface of one side of the handle body 1, a first telescopic metal tube 7 is provided inside the metal direction rotator 8, a second telescopic metal tube 11 is movably embedded inside the first telescopic metal tube 7, a plurality of sliding components 12 are provided inside the second telescopic metal tube 11, a laser fiber 5 is fixedly installed inside the plurality of sliding components 12, and one of the laser fibers 5 is provided. A laser knife body 10 is provided at the end, a closing clip 9 is provided on the outer surface of the laser knife body 10, and a double-button laser 4 is provided on the outer surface of the handle body 1; a protective component 2, the protective component 2 includes a U-shaped rod 201, a fixed block 202 is fixedly installed on the outer surface of the U-shaped rod 201, a magnet positive pole 203 is fixedly installed inside the fixed block 202, the outer surface of the magnet positive pole 203 is magnetically connected to the magnet negative pole 204, and the outer surface of the magnet negative pole 204 is fixedly installed with a connecting block 205; the pressing mechanism 3 includes a clamping machine body 301, and a connecting plate 303 is fixedly installed on the outer surface of the clamping machine body 301 near the top.

[0034] At the same time, as shown in Figures 1-5 and 7-8, the inner wall of the splint body 301 is fixedly connected with an anti-slip pad 302, and multiple sliding components 12 all include a limit ring 1201, and the outer surfaces of the multiple limit rings 1201 are provided with multiple circular grooves 1202, and the interiors of the multiple circular grooves 1202 are movably embedded with balls 1203. The inner walls of the multiple limit rings 1201 are fixedly connected to the outer surface of the laser optical fiber 5 near one end, and the outer surfaces of the multiple balls 1203 are in contact with the inner wall of the second telescopic metal tube 11. Under the action of the anti-slip pad 302, the softness is increased, the comfort when holding and pressing is improved, and the friction between the hand and the splint body 301 can be increased, reducing the possibility of slipping. When the second telescopic metal tube 11 moves, it contacts the multiple balls 1203. Under the action of the multiple balls 1203, the contact area between the second telescopic metal tube 11 and the laser optical fiber 5 is reduced, the friction is reduced, and the sliding of the second telescopic metal tube 11 is more stable.

[0035] As shown in Figures 1-3 and 6-7, a connector 6 is provided at the other end of the laser fiber 5. Two connecting rods 15 are fixedly mounted on the outer surface of the first telescopic metal tube 7 near one end. Two rotating grooves 16 are defined on the outer surface of the closing clamp 9. The outer surfaces of the two connecting rods 15 are movably embedded in the two rotating grooves 16. Two first sliding holes 14 are defined on the outer surface of the second telescopic metal tube 11 near one end. The connector 6 facilitates connection to an external laser therapy device. The laser therapy device emits laser light, which is then introduced into the laser fiber 5 through the connector 6, facilitating subsequent surgical operations. The first sliding holes 14, rotating grooves 16, and connecting rods 15 are coupled with the fixing rod 13 and the second telescopic metal tube 11 to facilitate the closing of the closing clamp 9 and the clamping of the tissue by the pressing mechanism 3.

[0036] As shown in Figures 1, 3 and 8, fixed rods 13 are fixedly installed on opposite sides of the interior of the closing clamp 9, and the outer surfaces of the two fixed rods 13 are movably embedded in the two first sliding holes 14, respectively. The front and rear surfaces of the connecting plate 303 are provided with second sliding holes 304, and a moving block 306 is movably embedded in the interior of the connecting plate 303. Two reinforcing rods 307 are fixedly installed on the front and rear surfaces of the moving block 306, wherein the outer surfaces of the two reinforcing rods 307 are movably embedded in the two second sliding holes 304, respectively, so that the connecting plate 303 drives the reinforcing rods 307 embedded in the second sliding holes 304 to move, thereby driving the moving block 306 to move.

[0037] As shown in Figures 1-2 and 6-8, one end of the moving block 306 is fixedly connected to a spring 308, one end of the spring 308 is fixedly installed on the inner wall of one side of the handle body 1, and a fixed plate 19 is fixedly installed inside the handle body 1. One end of the spring 308 can move through the outer surface of the fixed plate 19. Under the action of the spring 308, the closing clamp 9 can be automatically opened and closed when the clamp machine body 301 is released.

[0038] As shown in Figures 1-3 and 6-8, a connecting piece 310 is provided inside the handle body 1, and a fixing ring 311 is fixedly installed on the outer surface of the connecting piece 310. The outer surface of the fixing ring 311 is movably sleeved with an arc-shaped clamping plate 309. The bottom of the arc-shaped clamping plate 309 is fixedly connected to the top of the moving block 306. The outer surface of the second telescopic metal tube 11 near the other end is fixedly connected to the inside of the connecting piece 310, so that when the moving block 306 moves, the arc-shaped clamping plate 309 is driven to move, and the connecting piece 310 and the second telescopic metal tube 11 are pulled to move through the fixing ring 311, so that the closing clamp 9 closes and clamps the tissue.

[0039] As shown in Figures 7 and 8, the front and rear surfaces of the connecting plate 303 near the top are fixedly installed with a center rod 305, and the front and rear walls of the handle body 1 are fixedly installed with a center column 17. One end of the two center rods 305 is movably embedded in the interior of the two center columns 17. With the cooperation of the center columns 17 and the center rods 305, the connecting plate 303 is limited and installed, so that the clamping machine body 301 can drive the connecting plate 303 to move.

[0040] As shown in Figures 7 and 8, a movable hole 20 is opened inside the handle body 1, and the outer surface of the connecting plate 303 is movably embedded in the movable hole 20. The slides 18 are fixedly installed on the opposite side of the handle body 1. Through the movable hole 20, the clamping machine body 301 can drive the connecting plate 303 to move normally, thereby facilitating the clamping function.

[0041] As shown in Figures 7 and 8, multiple reinforcement rods 307 are evenly divided into two groups. One end of the two groups of reinforcement rods 307 is movably embedded in the inside of the two slides 18. The slides 18 facilitate support for the moving block 306, which is conducive to the smooth movement of the moving block 306.

[0042] As shown in Figures 1-2, 5-6 and 8, the outer surface of the connecting block 205 is fixedly connected to the outer surface of the splint machine body 301 near the bottom, and the limiting blocks 206 are fixedly installed at both ends of the U-shaped rod 201. Both ends of the U-shaped rod 201 are movable and penetrate into the interior of the handle body 1. The U-shaped rod 201 is limited by the limiting blocks 206 and is better installed on the outer surface of the handle body 1.

[0043] The effect achieved by the entire mechanism is: when in use, the connector 6 adopts an SMA905 connector, which is connected to the laser therapy machine through the connector 6. The laser therapy machine emits lasers with wavelengths of 810nm, 980nm and 1064nm, which are connected to the connector 6, and the laser is introduced into the laser optical fiber 5 for transmission. The laser power of the laser therapy machine is set, and the double-button laser 4 is divided into two upper and lower laser trigger buttons. When cutting is required, press the upper laser trigger button to trigger high-power laser energy for cutting function, and press the lower laser trigger button to trigger low-power laser energy for hemostasis function. Both laser energies are emitted from the laser therapy machine and transmitted to the connector 6 of the clamp-type laser knife, and then the laser energy is transmitted to the laser by the laser optical fiber 5. The laser knife head and the end of the laser knife are processed by technology, which will convert the transmitted laser energy into heat energy for cutting, vaporization, hemostasis and ablation of tissue. When the clamping function is needed, the splint machine body 301 is triggered to drive the connecting plate 303 to move, and the two moving blocks 306 drive the moving block 306 to move and squeeze the spring 308, and then the arc-shaped clamping plate 309 drives the connecting piece 310 and the second telescopic metal tube 11 to move, so that the closing clamp 9 is closed toward the laser knife body 10 to clamp the tissue, and can be pulled or pulled. The closing clamp trigger transmission mechanism has elastic control, which can trigger the laser while triggering the closing clamp trigger to achieve clamping cutting, hemostasis and other operations. Loosening the splint machine body 301 can automatically open the closing clamp 9. When not When the function of clamping tissue is needed, the U-shaped rod 201 is rotated to rotate the fixing block 202 to the connecting block 205, so that the positive pole of the magnet 203 and the negative pole of the magnet 204 are magnetically attracted together, and the U-shaped rod 201 is fixed. The U-shaped rod 201 is used to support and limit the clamp machine body 301 to prevent the clamp machine body 301 from being accidentally pressed and causing accidental clamping of tissue, thereby achieving a protective effect and solving the problem that the medical clamp-type laser knife can simultaneously take into account the functions of cutting, hemostasis and clamping tissue during surgery. The function of clamping tissue needs to be achieved by pressing the closed splint machine, but the medical clamp-type laser knife needs to hold the handle when in use, and the closed splint machine is close to the handle. When taking the handle, if you don't press it, it will be difficult to move it. Be careful that it is easy to press the closed splint, thereby clamping the tissue when the clamping function is not needed, which affects the surgical operation. The inner wall of the splint body 301 is installed with an anti-slip pad 302, which increases the softness and improves the comfort when holding and pressing. It can also increase the friction between the hand and the splint body 301 and reduce the possibility of slipping. When clamping is performed by the pressing mechanism 3, a plurality of sliding components 12 are set between the second telescopic metal tube 11 and the laser optical fiber 5. When the second telescopic metal tube 11 moves, it contacts with a plurality of ball bearings 1203. Under the action of the plurality of ball bearings 1203, the contact area between the second telescopic metal tube 11 and the laser optical fiber 5 is reduced, the friction is reduced, and the sliding of the second telescopic metal tube 11 is more stable.
