Description

Technical Field

[0001] This utility model relates to the field of otological surgical equipment technology, specifically an adjustable otological surgical electrode. Background Technology

[0002] Currently, tympanic membrane repair is usually performed using a skin flap around the ear canal. Existing techniques involve cutting the skin flap in the ear canal with the sharp edge of a metal instrument, and then separating the flap from the ear canal with the metal instrument. This separation process is prone to bleeding, resulting in a poor surgical field and making it impossible to perform precise surgery. At the same time, the fixed-length electrode may not be able to perfectly adapt to the cochlear structure of all patients, which may result in the electrode not being able to accurately reach the required location.

[0003] For example, the scalpel disclosed in the authorized patent document with application number CN202222332014.6 includes a blade head and a handle. One end of the blade head is threadedly connected to the end of the handle. A blade is fixedly installed on the blade head. The length of the handle is greater than or equal to 20cm. This scalpel is also more convenient to use in minimally invasive ventricular recanalization surgery with a narrow operating range, reducing the difficulty of the surgery, avoiding accidental damage to the tissues surrounding the myocardium, and improving the surgical efficacy.

[0004] The aforementioned patent suggests that electrodes of fixed length may not perfectly fit the cochlear structure of all patients, which could result in the electrodes not accurately reaching the required location. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an adjustable otological surgical electrode, comprising:

[0027] Handle body 1 and outer steel tube 2 slidably installed inside handle body 1;

[0028] The handle body 1 is equipped with a length adjustment mechanism 3 for adjusting the length of the electrode.

[0029] An electrode hemostasis mechanism 4 is provided on one side of the outer steel tube 2 for cutting the skin flap and achieving hemostasis;

[0030] Specifically, a length adjustment mechanism 3 is installed on the handle body 1 to allow the outer steel tube 2 to slide within the handle body 1 and adjust the movement of the blade part 41. By adjusting the electrode length, unnecessary damage to the internal structure of the cochlea can be avoided. For patients with small or abnormally shaped cochleas, using a shorter electrode can reduce pressure and damage to the delicate internal structures of the cochlea. At the same time, it avoids the electrode being too long and penetrating too deeply into the cochlea.

[0031] Furthermore, under irrigation, the surgical electrode is connected to the plasma surgical device. The sharp ceramic blade is used to cut the skin flap. After bleeding, the coagulation pedal of the plasma surgical device is pressed, and the coagulation plate 42 of the electrode outputs energy to achieve hemostasis of the tissue. The irrigation fluid washes away the overflowing blood, resulting in a clear surgical field.

[0032] The electrode hemostasis mechanism 4 includes a blade part 41 disposed on one side of the outer steel tube 2, a gap is provided between the outer steel tube 2 and the blade part 41, and a coagulation patch 42 is disposed on one side of the blade part 41.

[0033] In this embodiment, a gap is provided between the outer steel tube 2 and the blade 41 for irrigation operation. The sharpness of the ceramic blade is used to cut the skin flap. After bleeding, the coagulation pedal of the plasma surgical device is stepped on, and the coagulation plate 42 of the electrode outputs energy to complete the hemostasis of the tissue. At the same time, two buttons are provided on the surface of the handle body 1 for controlling the micro cylinder 31 to realize the control and adjustment of the cylinder. When one end of the cylinder is extended, the piston 30 is pushed. Gas is provided between the two pistons 30. The gas is located in the rotary air tube. The movement of one piston 30 will push the movement of the other piston 30, thereby controlling the movement of the push rod 33 to drive the movement of the movable ring 6. The movable ring 6 drives the outer steel tube 2 to move and adjust, thereby controlling the movement of the blade 41 and controlling the length.

[0034] Furthermore, the gas inside the rotary pipe 32 is a gas with strong intermolecular forces. Although the intermolecular forces of gas molecules are usually weak, when the gas is compressed, the distance between molecules decreases, and the intermolecular repulsion begins to take effect. For some gases with strong intermolecular forces, this repulsion will resist the pressure applied from the outside, making it difficult for the gas to be further compressed.

[0035] The blade part 41 is provided with a ceramic blade, and a wire 5 is provided on one side of the blade part 41. One end of the wire 5 passes through one side of the handle and extends thereto, and a connecting wire is provided on one end of the wire 5.

[0036] It is worth noting that the ceramic blade is made of sintered zirconium oxide ceramic, with sharp edges and a hole at the top. The wire 5 of the coagulation patch 42 can be threaded through the hole, and the wire 5 can be threaded to the connecting wire and connected to the positive terminal of the connecting wire.

[0037] A movable ring 6 is fixedly installed on the surface of the outer steel pipe 2. The surface of the movable ring 6 is slidably installed on the inner wall of the handle body 1, and the length adjustment mechanism 3 is used in conjunction with the movable ring 6.

[0038] Furthermore, the length adjustment mechanism 3 pushes the movable ring 6 to move, and the movable ring 6 is fixedly connected to the outer steel pipe 2, pushing the outer steel pipe 2 to move. The wire 5 is movably set inside the outer steel pipe 2 and moves with the blade part 41.

[0039] The length adjustment mechanism 3 includes a miniature cylinder 31 disposed on one side of the handle body 1. The handle body 1 has a rotary pipe 32 embedded inside. Two pistons 30 are disposed inside the rotary pipe 32. The extension end of the miniature cylinder 31 is mounted on the surface of the piston 30. A push rod 33 is fixedly mounted on one side of the movable ring 6. One end of the push rod 33 is fixedly mounted on the surface of the other piston 30.

[0040] It should be noted that when one end of the starting cylinder extends, the piston 30 is pushed. There is gas between the two pistons 30, which is located in the rotary air pipe. The movement of one piston 30 will push the movement of the other piston 30, thereby controlling the movement of the push rod 33 to drive the movement of the movable ring 6. The movable ring 6 drives the outer steel pipe 2 to move and adjust, thereby controlling the movement of the blade part 41 and controlling the length.

[0041] The piston component 30 includes a movable seat 301 disposed in the rotary pipe 32, and a sealing cylinder 302 is fixedly installed in the groove on the surface of the movable seat 301. The surface of the sealing cylinder 302 is in close contact with the inner wall of the rotary pipe 32.

[0042] The groove on the movable seat 301 is used to limit the sealing cylinder 302, and the sealing cylinder 302 is a rubber cylinder. The surface of the sealing cylinder 302 is in close contact with the inner wall of the rotary pipe 32, thereby achieving good sealing performance.

[0043] The surface of the movable ring 6 is provided with three small grooves 7, and small slide rails 8 are slidably installed inside the three small grooves 7. The three small slide rails 8 are fixedly installed on the inner wall of the handle body 1.

[0044] Specifically, since the surface of the movable ring 6 has three evenly distributed small sliding grooves 7, during the movement of the movable ring 6, the sliding grooves slide within the slide rails, that is, the movable ring 6 slides on the three small slide rails 8, which provides a strong guiding effect for the movement of the movable ring 6.

[0045] A guide cylinder 9 is fixedly installed on one side of the handle body 1. The inside of the guide cylinder 9 is slidably installed with the surface of the outer steel tube 2. A protective cover 10 for protecting the miniature cylinder 31 is installed on the surface of the handle body 1.

[0046] In order to make the movement of the outer steel pipe 2 more stable and provide a better directional movement effect, a guide cylinder 9 is set to guide the movement of the outer steel pipe 2, and a protective cover 10 is set to protect the miniature cylinder 31. Since the handle body 1 is small, the miniature cylinder 31 is placed on the outside, which also facilitates the maintenance of the miniature cylinder 31.

[0047] A gap is provided between the outer steel tube 2 and the blade 41 of this device for irrigation operation. The sharpness of the ceramic blade is used to cut the skin flap. After bleeding, the coagulation pedal of the plasma surgical device is stepped on, and the coagulation plate 42 of the electrode outputs energy to complete the hemostasis of the tissue. At the same time, two buttons are provided on the surface of the handle body 1 for controlling the micro cylinder 31 to realize the control and adjustment of the cylinder. When one end of the cylinder is extended, the piston 30 is pushed. Gas is provided between the two pistons 30. The gas is located in the rotary air tube. The movement of one piston 30 will push the movement of the other piston 30, thereby controlling the movement of the push rod 33 to drive the movement of the movable ring 6. The movable ring 6 drives the outer steel tube 2 to move and adjust, thereby controlling the movement of the blade 41 and controlling the length.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
