Description

Technical Field

[0001] This utility model relates to a suction and cutting forceps for laryngeal polyps. Background Technology

[0002] Laryngeal polyp forceps are used to remove laryngeal polyps. Existing laryngeal polyp forceps, such as the irrigation laryngeal polyp forceps in application number 201120065541.4, have a cutting part consisting of a fixed forceps head and a movable forceps head, forming a scissor-like structure. When cutting laryngeal polyps, the two forceps heads need to be opened and then closed. Since the laryngeal region has a curved shape and relatively small operating space, and to ensure thorough polyp removal, the forceps heads must be close to the base of the polyp. During the closing of the forceps heads, the tip of the forceps head can easily scratch the surrounding normal mucosa tissue of the laryngeal polyp. This requires extreme care and is quite difficult to operate. Therefore, existing laryngeal polyp forceps have the drawback of being difficult to operate. Utility Model Content

[0003] The purpose of this invention is to provide a suction and cutting forceps for laryngeal polyps. This invention has the following advantages.

[0004] The technical solution of this utility model is as follows: A suction and cutting forceps for laryngeal polyps includes a fixed handle, the upper end of which is bent forward to form a mounting base. A guide block is provided on the upper side of the mounting base, and a guide tube extending forward is provided inside the guide block. A cutting hole is provided on one side of the front end of the guide tube. An axially hollow movable block is provided behind the mounting base, and a pipe joint is provided on the rear side of the movable block. A cutting tube extending forward into the guide tube is provided inside the movable block. A chamfer is provided at the inner hole of the front end of the cutting tube to form an annular cutting edge at the front end of the cutting tube. A movable handle is hinged to the front side of the fixed handle, and the upper end of the movable handle is movably connected to the movable block.

[0005] In the aforementioned laryngeal polyp suction and cutting forceps, a vertical through hole is provided at the connection between the fixed forceps handle and the mounting base, and a groove is provided on the bottom surface of the movable block above the through hole. The upper end of the movable forceps handle passes through the through hole and is provided with a toggle head located in the groove.

[0006] In the aforementioned laryngeal polyp suction and cutting forceps, the outer periphery of the guide tube is provided with a suction hole, the suction hole and the cutting hole are located on the same side of the guide tube, the suction hole is located in front of the cutting hole, the inner hole of the front end of the guide tube is closed, the outer periphery of the guide tube is provided with a limiting elongated hole, and a limiting slider fixed to the cutting tube is provided in the limiting elongated hole.

[0007] In the aforementioned laryngeal polyp suction and cutting forceps, the front side of the guide block is provided with a rotating wheel through which the guide tube passes axially, the guide tube is fixed to the rotating wheel, and the rotating wheel is rotatably connected to the guide block; the rear end of the cutting tube is fixed to the movable block.

[0008] In the aforementioned throat polyp suction and cutting forceps, there are multiple suction holes.

[0009] In the aforementioned laryngeal polyp suction and cutting forceps, the guide block is connected to the mounting base by screws.

[0010] In the aforementioned laryngeal polyp suction and cutting forceps, both the lower end of the fixed forceps handle and the lower end of the movable forceps handle are provided with finger rings.

[0011] Compared with existing technologies, this invention features a cutting hole at the front end of a guide tube, a cutting tube inside the guide tube, and an annular cutting edge at the front end of the cutting tube. The cutting edge is used to cut off laryngeal polyps that have entered the cutting hole. Because the cutting edge remains inside the guide tube and is not exposed, the mucosal tissue near the laryngeal polyp is not damaged, thus reducing the difficulty of operation. Therefore, this invention has the advantage of being easier to operate.

[0012] In addition, since the guide tube is rotatably connected to the guide block and fixed to the rotating wheel, the guide tube can rotate freely under the drive of the rotating wheel, and the orientation of the incision can be changed, making it easier to align with the laryngeal polyp and making it easier for the laryngeal polyp to enter the incision, further reducing the difficulty of operation.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example: A suction and cutting forceps for laryngeal polyps, such as Figure 1 As shown, it includes a fixed clamp handle 1, the upper end of the fixed clamp handle 1 is bent forward to form a mounting base 2, and a guide block 3 is provided on the upper side of the mounting base 2. The guide block 3 is connected to the mounting base 2 by screws 17.

[0020] The guide block 3 has a forward-extending guide tube 4 inside, the rear end of the guide tube 4 is aligned with the rear end of the guide block 3, and the guide tube 4 is rotatably connected to the guide block 3. The front end of the guide tube 4 has a cutting hole 5, the axial length of the cutting hole 5 is 4mm and the width is 3mm. The wrap angle of the cutting hole 5 on the guide tube 4 is about 180°. The mounting base 2 has an axially hollow movable block 6 behind it. The movable block 6 has a pipe joint 7 on its rear side. The movable block 6 has a cutting tube 8 that extends forward into the guide tube 4 inside it. The cutting tube 8 is rotatably connected to the movable block 6. The outer diameter of the cutting tube 8 matches the inner diameter of the guide tube 4. The inner hole at the front end of the cutting tube 8 has a chamfer 9, so that the front end of the cutting tube 8 forms an annular cutting edge.

[0021] A movable handle 10 is hinged to the front side of the fixed handle 1. A vertical through hole 11 is provided at the connection between the fixed handle 1 and the mounting base 2. The through hole 11 is a flat square hole. A groove 12 is provided on the bottom surface of the movable block 6 above the through hole 11. The upper end of the movable handle 10 passes through the through hole 11 and is provided with an actuating head 13 located in the groove 12. Both the lower end of the fixed handle 1 and the lower end of the movable handle 10 are provided with finger rings 18.

[0022] The guide tube 4 has three suction holes 14 on its outer periphery. The sum of the cross-sectional areas of the three suction holes 14 is less than the cross-sectional area of ​​the cutting hole 5. The suction holes 14 and the cutting hole 5 are located on the same side of the guide tube 4. The suction holes 14 are located in front of the cutting hole 5. The inner hole at the front end of the guide tube 4 is closed. The guide tube 4 has a limiting elongated hole 15 on its outer periphery. A limiting slider 16 fixed to the cutting tube 8 is provided in the limiting elongated hole 15.

[0023] The front side of the guide block 3 is provided with a rotating wheel 19 through which the guide tube 4 passes axially. The guide tube 4 is fixed to the rotating wheel 19, and the rotating wheel 19 is rotatably connected to the guide block 3. The rear end of the cutting tube 8 is fixed to the movable block 6.

[0024] Preferably, an O-ring can be provided between the guide block 3 and the rotating wheel 19 to provide damping when they rotate relative to each other.

[0025] Instructions for use: Hold the fixed clamp handle 1 and the movable clamp handle 10. When the fixed clamp handle 1 and the movable clamp handle 10 are opened, the upper end of the movable clamp handle 10 moves backward, which drives the movable block 6 to move backward through the toggle head 13. The movable block 6 drives the cutting tube 8 to move backward through the pin 21, so that the front end of the cutting tube 8 is located behind the cutting hole 5.

[0026] Insert the front end of the guide tube 4 into the laryngeal polyp and allow the laryngeal polyp to enter the incision hole 5. Combine the fixed clamp handle 1 and the movable clamp handle 10, and move the cutting tube 8 forward to cut off the laryngeal polyp through the cutting edge at its front end.

[0027] During the removal of laryngeal polyps, rotating the wheel 19 causes the guide tube 4 to rotate, which can change the orientation of the incision hole 5, making it easier for the laryngeal polyp to enter the incision hole 5 and making the operation more convenient.

[0028] During the removal of laryngeal polyps, when the connector 7 is connected to the irrigation device, the irrigation fluid from the irrigation device flows through the connector 7 and the cutting tube 8, exiting from the irrigation and suction port 14. This flushes away foreign objects in the larynx, improving the field of vision. When the connector 7 is connected to the suction device, it facilitates the suction of the patient's laryngeal irrigation fluid. During irrigation and suction, the fixed forceps 1 and the movable forceps 10 are in a combined state to prevent the irrigation fluid from passing through the cutting hole 5. The larger diameter of the cutting hole 5 would reduce the suction force. When the fixed forceps 1 and the movable forceps 10 are combined, the limiting slider 16 is located at the front end of the limiting elongated hole 15. When the fixed forceps 1 and the movable forceps 10 are open, the limiting slider 16 is located at the rear end of the limiting elongated hole 15.

[0029] The advantages of this embodiment are that it is easy to operate, has a simple structure, and is relatively inexpensive.
