Description

Technical Field

[0001] This utility model relates to the field of laryngeal mucosal forceps technology, specifically a graduated and bendable laryngeal mucosal forceps. Background Technology

[0002] Laryngeal mucosal forceps are widely used in laryngeal surgeries, including laryngoscopy, laryngeal biopsy, laryngeal vacuum aspiration, and laryngeal mucosal resection. Their function is to clamp the laryngeal mucosa to prevent it from obscuring the surgical area and to keep the larynx clear. At the same time, laryngeal mucosal forceps can also help surgeons to firmly fix the larynx to ensure the accuracy and safety of the surgery. They are characterized by simple operation and safety and reliability, and are widely recognized and used.

[0003] Laryngeal surgery requires adjusting the angle at which the laryngeal mucosa is clamped. This adjustment requires a high degree of precision, which puts a lot of pressure on the surgeon. However, commercially available laryngeal mucosa clamps are difficult to adjust precisely and rely heavily on the surgeon's experience.

[0004] To address this issue, the present invention provides a graduated and bendable laryngeal mucosal forceps. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a graduated and bendable laryngeal mucosal forceps, which solves the problem of the difficulty in making precise angle adjustments to laryngeal mucosal forceps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a graduated and bendable laryngeal mucosal forceps, comprising a forceps head, a forceps bar, a push rod, and a forceps body. The forceps head includes a movable forceps head and a fixed forceps head, which are hinged together. One end of the fixed forceps head is fixedly connected to the forceps bar. A retrieval groove is provided on the surface of the forceps head. One end of the forceps bar is fixedly connected to the forceps body. The push rod is disposed inside the forceps bar, and one end of the push rod is hinged to the movable forceps head. A slot is provided on the surface of the push rod. A front handle is fixedly connected to the surface of the forceps body. A through hole adapted to the push rod is provided inside the forceps body. A closed-hole plug is connected to one side of the forceps body via an open thread. A thick handle receiving groove is provided at the bottom of the forceps body. A rear handle is rotatably connected to the rear part of the front handle via a pin. A push block is fixedly connected to the top of the rear handle. The push block extends into the thick handle receiving groove, and the top of the push block is fixedly connected to the push rod.

[0007] Preferably, the pliers head is trapezoidal, and a biting pattern is provided on one side of the pliers head.

[0008] Preferably, a threaded head is fixedly connected to one side of the occluder plug, and a bayonet is provided on the other side of the occluder plug.

[0009] Preferably, the surface of the clamp bar is provided with bending scale.

[0010] Beneficial effects

[0011] This invention provides a graduated and bendable laryngeal mucosal forceps. Compared with existing technologies, it has the following advantages:

[0012] (1) This utility model adjusts the clamping angle with high precision by bending the scale at the front end of the clamp rod. It has a reasonable structure, is easier to operate, improves surgical efficiency, and reduces the surgical pressure on doctors.

[0013] (2) The utility model has a trapezoidal pliers head with a meshing pattern on the closed surface, which can greatly improve the clamping safety and stability.

[0014] (3) The utility model has a through-hole design at both ends of the clamp body. The push rod can be removed by opening the closed hole plug at the rear end, which is convenient for disassembly and internal cleaning and disinfection. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-7 This utility model provides a technical solution: a graduated and bendable laryngeal mucosal forceps, comprising a forceps head 1, a forceps bar 2, a push rod 3, and a forceps body 4. The forceps head 1 includes a movable forceps head 11 and a fixed forceps head 12, which are hinged together. One end of the fixed forceps head 12 is fixedly connected to the forceps bar 2. A retrieval groove 13 is provided on the surface of the forceps head 1. One end of the forceps bar 2 is fixedly connected to the forceps body 4. The push rod 3 is disposed inside the forceps bar 2, and one end of the push rod 3 communicates with the movable forceps head 11. The push rod 3 is hinged via a hinge. A slot 31 is provided on the surface of the push rod 3. A front handle 5 is fixedly connected to the surface of the clamp body 4. A through hole adapted to the push rod 3 is provided inside the clamp body 4. A closed-hole plug 7 is connected to one side of the clamp body 4 by an open thread. A thick handle groove 41 is provided at the bottom of the clamp body 4. A rear handle 6 is rotatably connected to the rear part of the front handle 5 by a pin 9. A push block 61 is fixedly connected to the top of the rear handle 6. The push block 61 extends into the interior of the thick handle groove 41. The top of the push block 61 is fixedly connected to the push rod 3.

[0025] It should be noted that the front end of the forceps head 1 is at a 30° bevel, the forceps bar 2 itself is made of high-toughness metal and can be bent according to the scale to adjust the surgical angle, and the push rod 3 is slender and tough.

[0026] Furthermore, in order to improve the safety and stability of the clamping of the pliers head 1, the pliers head 1 is trapezoidal, and a biting groove 14 is provided on one side of the pliers head 1.

[0027] Furthermore, in order to facilitate the disassembly, cleaning and disinfection of the push rod 3, a connecting thread head 71 is fixedly connected to one side of the closed hole plug 7, and a bayonet 72 is provided on the other side of the closed hole plug 7.

[0028] Furthermore, to improve the accuracy of angle adjustment, the surface of the clamp 2 is provided with bending scale 8.

[0029] In use, the forceps head 1 is composed of a fixed forceps head 12 and a movable forceps head 11 hinged together. By holding the front handle 5 and the rear handle 6, and rotating the rear handle 6 towards the front handle 5, the rear handle 6 will cause the push block 61 to tilt. The push block 61 will pull the push rod 3 to move to the right, causing the push rod 3 to tilt the movable forceps head 11, opening the movable forceps head 11 and the fixed forceps head 12 to adjust the clamping angle. Then, rotating the rear handle 6 in the opposite direction will cause the push block 61 to move the push rod 3 in the opposite direction, causing the push rod 3 to move the movable forceps head 11 towards the fixed forceps head 12, so that the movable forceps head 11 and the fixed forceps head 12 are combined for clamping. The clamping angle can be adjusted with high precision by bending the scale 8 at the front end of the forceps bar 2, improving surgical efficiency and reducing the surgeon's surgical pressure. The forceps head 1 is a trapezoidal forceps head 1 with a biting groove 14 on the closed surface to improve clamping safety and stability. The forceps body 4 has a through-hole design at both ends. The push rod 3 can be removed by opening the closed hole plug 7 at the rear end, which is convenient for disassembly and internal cleaning and disinfection.
