Laryngeal micro-suction dissector

Abstract

This utility model provides a laryngeal microsurgical suction dissector, relating to the field of medical devices. The microsurgical suction dissector includes a hollow extension portion. The tail end of the extension portion has a connection port, and the middle portion has a through hole communicating with the outside. The head end of the extension portion is a downwardly curved, flat dissection unit. The extension portion has a drainage hole communicating with the dissection unit, and a control unit communicating with the through hole is located above the extension portion. This laryngeal microsurgical suction dissector uses the end face formed by the head of the extension portion for dissection, and drainage holes are provided on both sides away from the dissection surface. This allows the drainage holes to separate from the dissection unit, preventing tissue detachment during dissection from blocking the drainage holes. Simultaneously, inward recesses are first formed on both sides of the head of the extension portion before the drainage holes are formed. This ensures that when the head of the extension portion contacts the tissue, the reserved recessed portion on the side can be kept away from the tissue for ventilation, preventing the drainage holes from being blocked.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a laryngeal microsurgical suction dissector. Background Technology

[0002] Currently, microsurgical laryngeal dissectors and microsurgical aspirators are separate instruments. Because microsurgical laser minimally invasive surgery is performed under a laryngoscope, space limitations make it difficult for the surgeon to insert multiple instruments simultaneously. Furthermore, during the procedure, the surgeon often needs one hand to operate the laser for cutting or hemostasis, while the other hand uses the aspirator to remove blood vapor. Sometimes, the suction force is also needed to pull tissue and expose the surgical field. Otherwise, the aspirator and dissector are repeatedly changed, resulting in low efficiency, prolonged surgery time, and increased patient risk. However, current conventional laryngeal aspirators cannot simultaneously meet the demands of prolonged procedures involving tissue traction, blood removal, and aspiration.

[0003] Existing patent (CN209285920U) discloses an ear microsurgical suction cutting and dissecting device, comprising a hollow tube and a connector attached to one end of the hollow tube. The other end of the hollow tube has a cutting section, and the tube wall has an adjustment hole. The two ends of the adjustment hole communicate with the inner cavity of the hollow tube and the outside, respectively. The connector is used to connect to an external suction device. During surgery, the hollow tube is inserted into the ear, and the cutting section is used to cut and dissect the surgical site. The suction device draws air into the inner cavity of the hollow tube, promptly drawing in bleeding and expelling it. The suction force within the hollow tube can be adjusted by closing the adjustment hole to prevent excessive suction. This technical solution has a simple structure and is convenient and flexible to operate. It can simultaneously cut and dissect while simultaneously suctioning blood, ensuring a clear surgical field and improving surgical quality. However, because the cutting and dissecting part and the suction part are located on the same plane, the dissected tissue is easily drawn into the inner cavity during the dissection process, causing blockage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a laryngeal microsurgical suction and dissection device, which solves the problem mentioned in the background art that existing devices are prone to clogging the internal cavity.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a laryngeal microscopic suction peeler, comprising a hollow extension, a connection port at the tail end of the extension, a through hole communicating with the outside in the middle of the extension, a flat peeling unit bent downward at the head end of the extension, a drainage hole communicating with the extension at the peeling unit, and a control unit communicating with the through hole at the top of the extension, wherein the control unit changes the ventilation volume by pressing.

[0007] Furthermore, a handle is fixedly installed on the outer surface of the extension located at the through hole.

[0008] Furthermore, the control unit includes a cavity fixed to the surface of the extension and communicating with the through hole. The surface of the cavity is covered with an elastic film, and a notch is opened in the middle of the elastic film. When the elastic film at the edge of the notch is pressed, the notch deforms and increases its area.

[0009] Furthermore, the control unit includes a sealing box fixedly installed on the surface of the extension and communicating with the through hole. The sealing box has a conical exhaust port. A support frame is fixedly installed inside the sealing box. A spring is fixedly installed at the top middle part of the support frame. A conical sealing gasket that is slidably connected inside the conical exhaust port is fixedly installed at the free end of the spring. A pressure rod is fixedly installed at the top of the conical sealing gasket.

[0010] Furthermore, the control unit includes a square box that is fixedly mounted on the surface of the extension and communicates with the through hole, and the surface of the square box has an elongated exhaust port with a gradually increasing width.

[0011] Furthermore, the head end of the extension is arc-shaped, and the two sides taper towards the center to form a thin wall.

[0012] Furthermore, the extension peeling unit only contracts towards the center at its bottom end to form a thin wall, and the drainage hole is located at the thin wall and the top arc of the peeling unit.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This laryngeal microsurgical aspiration dissector uses the end face formed by the head of the extended part for dissection, and provides drainage holes on both sides away from the dissection surface. This allows the drainage holes to be separated from the dissection unit, preventing the dislodged tissue from blocking the drainage holes during the dissection process. At the same time, the extension head is first provided with inward recesses on both sides before the drainage holes are opened. When the extension head comes into contact with the tissue, the side recesses are reserved to allow ventilation away from the tissue, preventing the drainage holes from being blocked.

[0015] 2. This laryngeal microsurgical suction dissector includes a control unit comprising a sealed box fixedly mounted on the surface of the extension and communicating with a through hole. The sealed box has a conical exhaust port. A support frame is fixedly mounted inside the sealed box. A spring is fixedly mounted at the top of the middle part of the support frame. A conical sealing gasket, which is slidably connected inside the conical exhaust port, is fixedly mounted at the free end of the spring. A pressure rod is fixedly mounted at the top of the conical sealing gasket. This technical solution increases the sealing structure, but it can form a seal by using the spring to compress the conical sealing gasket to cover the conical exhaust port when not pressed, thereby avoiding the need for doctors to deliberately block the hole used for exhaust.

[0016] 3. The laryngeal micro-suction stripper includes a control unit consisting of a square box fixedly mounted on the surface of the extension and connected to the through hole. The surface of the square box has a long exhaust port with a gradually increasing width. This configuration is relatively simple. By changing the area covered by the thumb in the long exhaust port, the amount of exhaust can be changed. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-5The laryngeal microsurgical aspiration dissector includes a hollow extension 1, a connection port 2 at the tail end of the extension 1, a through hole 3 in the middle of the extension 1 communicating with the outside, and a downwardly curved, flat dissecting unit at the head end of the extension 1. A drainage hole 6 communicating with the extension 1 is located at the dissecting unit. A control unit 4 communicating with the through hole 3 is located above the extension 1. The control unit 4 changes the ventilation volume by pressing. The end face formed by the head of the extension 1 is used for dissection, and drainage holes 6 are provided on both sides away from the dissection surface. This allows the drainage holes 6 to separate from the dissection unit, preventing tissue from clogging the drainage holes 6 during the dissection process. Simultaneously, inward recesses are first formed on both sides of the head of the extension 1 before the drainage holes 6 are opened. This ensures that when the head of the extension 1 contacts the tissue, the lateral recesses are reserved to allow ventilation away from the tissue, preventing the drainage holes 6 from being blocked.

[0025] A handle 5 is fixedly installed on the outer surface of the extension 1 at the through hole 3, which makes it easy to hold.

[0026] The control unit 4 includes a cavity 401 fixed to the surface of the extension 1 and communicating with the through hole 3. The surface of the cavity 401 is covered with an elastic film 402. A notch 403 is provided in the middle of the elastic film 402. When the elastic film 402 at the edge of the notch 403 is pressed, the notch 403 deforms and increases its area. This technical solution has a low cost and can quickly achieve the effect of changing the amount of exhaust.

[0027] The control unit 4 includes a sealing box 404 fixedly mounted on the surface of the extension 1 and communicating with the through hole 3. The sealing box 404 has a conical exhaust port 405. A support frame 406 is fixedly mounted inside the sealing box 404. A spring 407 is fixedly mounted at the top of the middle part of the support frame 406. A conical sealing gasket 408 is fixedly mounted at the free end of the spring 407 and slidably connected inside the conical exhaust port 405. A pressure rod 409 is fixedly mounted at the top of the conical sealing gasket 408. This technical solution increases the sealing structure, but it can form a seal by using the spring 407 to compress the conical sealing gasket 408 to cover the conical exhaust port 405 when not pressed, thereby avoiding the need for doctors to deliberately block the hole used for exhaust.

[0028] The control unit 4 includes a square box 410 that is fixedly installed on the surface of the extension 1 and communicates with the through hole 3. The surface of the square box 410 has a long exhaust port 411 with a gradually increasing width. This configuration is relatively simple. By changing the area covered by the thumb in the long exhaust port 411, the amount of exhaust can be changed.

[0029] The head end of the extension 1 is arc-shaped, and the two sides taper towards the center to form a thin wall. This design facilitates the dissection of tissue.

[0030] The extension 1 peeling unit only contracts towards the center at the bottom to form a thin wall. The drainage hole 6 is located at the thin wall and the top arc of the peeling unit. With this arrangement, when the pressure control part 4 increases the attraction force in the drainage hole 6, the drainage hole 6 located at the top can be tilted to pull the tissue. Since the drainage hole 6 that pulls the tissue is located above the peeling thin wall and is farther away from the traction tissue than the peeling thin wall, it is possible to avoid detachment from the tissue and blockage of the drainage hole 6.

[0031] When in use, the extension 1 is inserted into the operating area and the head end face of the extension 1 is used for peeling. When blood suction and smoking are required, the negative pressure device is connected through the drainage hole 6 on the side wall of the head of the extension 1 and the connection port 2 for drainage. When the drainage suction is too strong, the amount of discharge can be changed by pressing the control part 4, thereby reducing the drainage suction.

[0032] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
