Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable and easy-to-operate tracheostomy dilation device. Background Technology

[0002] Tracheostomy dilation is a surgical technique used to establish an airway. It is typically used for patients requiring long-term mechanical ventilation or other airway management needs. The main purpose of tracheostomy dilation is to surgically create an artificial airway in the anterior neck to facilitate respiratory support and airway management for the patient.

[0003] Percutaneous Dilatational Tracheostomy (PDT): This technique has become increasingly popular in recent years due to its minimally invasive nature and low complication rate. PDT involves making a small incision in the skin and then progressively dilating the anterior wall of the trachea using a series of dilators before finally inserting the tracheal cannula. This technique is typically performed at the bedside, reducing patient transport and operating room usage. The dilator plays a crucial role in this step, and several common dilator methods are currently used:

[0004] 1. Progressive dilator: This is the most common type of dilator. It usually consists of a series of dilators of different diameters. When operating, you start with a smaller diameter and gradually replace it with a larger one. Each time you replace the dilator, the enlarged orifice gradually increases until it reaches a size large enough to insert the tracheostomy tube.

[0005] 2. Dilatation forceps: This dilation method uses a dilatation forceps to dilate the endotracheal tube. The forceps are inserted through a guidewire into the endotracheal inlet, and then the forceps are pulled apart by hand to widen the tip of the tube. The forceps are widened to a certain size each time, and after repeated operation, the size of the endotracheal tube can be inserted.

[0006] 3. Conical dilators: These dilators have a conical design and gradually expand the anterior wall of the trachea through rotation and thrust during dilation. They are often used in specially designed PDT kits.

[0007] The current dilator design cannot visually display the dilation width at the current tracheal anterior wall incision, thus failing to provide a more intuitive and accurate assessment of whether dilation is complete and whether it meets the requirements for proceeding to the next step. Utility Model Content

[0008] The purpose of this utility model is to at least partially solve one of the technical problems in related technologies. Therefore, an adjustable and easily operable tracheostomy dilation device is provided, comprising: a platform with a movable channel in the middle; a fixed dilation plate, detachably and fixedly installed in the movable channel on the platform, the bottom end of which is adapted to be inserted into the tracheal anterior wall incision during tracheostomy as a dilation support structure; a movable dilation plate, linearly and reciprocally installed in the movable channel on the platform, the bottom end of which is adapted to cooperate with the fixed dilation plate in dilating the tracheal anterior wall incision; a dilation switch, controlling the movable dilation plate to move closer to or further away from the fixed dilation plate to adjust the dilation width at the tracheal anterior wall incision; and a dilation degree marking structure, provided on the platform, for indicating the dilation width.

[0009] According to an example of the present invention, the platform is provided with a fixing groove, and the fixed expansion piece is provided with an outer edge fixing boss on the side opposite to the moving expansion piece. The outer edge fixing boss is adapted to be inserted into the fixing groove, and the fixed expansion piece is detachably fixed in the fixing groove by fasteners.

[0010] According to an example of the present invention, the main bodies of the fixed expansion plate and the movable expansion plate have a semi-annular cross-section, and the main bodies of the fixed expansion plate and the movable expansion plate are closed in a cylindrical shape when in contact; the bottom ends of the fixed expansion plate and the movable expansion plate are both semi-trumpet-shaped; and the bottom ends of the fixed expansion plate and the movable expansion plate are closed in a trumpet shape when in contact.

[0011] According to one example of the present invention, the platform is provided with a linear slide rail, and the movable expansion piece is provided with a linear slide bar on the side away from the fixed expansion piece, and the linear slide bar is adapted to be slidably mounted on the linear slide rail.

[0012] According to one example of the present invention, the expansion switch is a rotary handle, which is connected to the moving expansion plate through a gear transmission structure. The gear transmission structure includes a gear rotatably mounted on a platform and a rack mounted on a linear slide bar that meshes with the gear. The rotary handle is connected to the gear through a rotating rod.

[0013] According to one example of the present invention, the expansion marking structure is a width scribe line or width ruler provided on the platform extending along the linear sliding direction of the moving expansion piece.

[0014] According to one example of the present invention, a motor connected to a moving expansion plate via a transmission structure is mounted on the platform, the expansion degree marking structure is a display screen connected to the motor, and the expansion switch is connected to the motor to control the motor's start / stop, rotation direction, torque magnitude, and motor driving stroke, which are displayed on the display screen.

[0015] According to one example of the present invention, a guide seat is detachably installed on the platform, the guide seat has a guide hole in the middle, and the movable expansion piece is provided with at least one guide rod extending in the same direction as the movable expansion piece for passing through the guide hole.

[0016] According to one example of the present invention, it also includes an instrument fixation bracket for mounting on an operating table, wherein the platform is detachably fixed to the instrument fixation bracket.

[0017] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0018] 1. Through innovative design of a new type of tracheostomy dilation device, with the platform as the main body, fixed dilation plates and dynamic dilation plates are set up to control the dilation of the tracheal anterior wall incision as needed by the dilation switch. The dilation operation is intuitive and clear. With the dilation degree marking structure set on the platform, the dilation width at the tracheostomy can be monitored in real time.

[0019] 2. The fixed and movable expansion plates, which serve as the main components for incision dilation, are cylindrical in shape with a tapered lower end in a trumpet shape when closed, facilitating efficient insertion into the anterior wall incision of the trachea and improving dilation efficiency.

[0020] 3. One design is a manual adjustment scheme. By rotating the handle and the gear transmission structure, the forward and reverse movement of the expansion plate is adjusted to adjust the expansion width at the bottom incision of the expansion plate. The expansion data can be accurately monitored in real time through the width markings or width ruler. The operation is labor-saving, stable and highly controllable, and the adjustment parameters are precise and unlikely to cause damage to the patient.

[0021] 4. The second design is an electric adjustment scheme. The motor and transmission structure are connected to the moving expansion plate. The start and stop of the motor, the direction of rotation, the torque and the stroke of the motor are operated by the expansion switch. The corresponding important parameters are displayed on the screen in real time. The difficulty of operation is reduced, which can save doctors' physical strength and improve the efficiency of surgical work.

Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0032] Among the various tracheal dilators currently in use, progressive dilators, while effectively opening the anterior tracheal wall, require numerous manipulations, increasing the workload for doctors. Furthermore, these dilators are only available in a few fixed sizes; additional dilators require custom customization, leading to high costs, low efficiency, and less convenient and smooth operation. Dilator forceps can open to different diameters as needed, but currently available forceps have the same force direction applied to the handle as the opening, meaning the handle opens outwards. This force application method requires doctors to use more force, increasing the difficulty and reducing accuracy. Due to the difficulty in applying force, repeated manipulations are also necessary to dilate the anterior tracheal wall. Conical dilators dilate the anterior tracheal wall through rotational thrust. This method requires high levels of strength and skill, has poor controllability, and is prone to causing tracheal damage due to excessive force.

[0033] Please see Figures 1-6 As shown, this utility model provides an adjustable and easy-to-operate tracheostomy dilation device, comprising: a platform 1, with a movable channel 2 in the middle of the platform 1; a fixed dilation plate 3, detachably and fixedly installed in the movable channel 2 on the platform 1, the bottom end of the fixed dilation plate 3 being suitable for being inserted into the tracheal anterior wall incision during tracheostomy as a dilation support structure for dilating the incision; a movable dilation plate 4, linearly and reciprocally installed in the movable channel 2 on the platform 1, the bottom end of the movable dilation plate 4 being suitable for cooperating with the fixed dilation plate 3 to dilate the tracheal anterior wall incision; a dilation switch 5, controlling the movable dilation plate 4 to move closer to or further away from the fixed dilation plate 3 to adjust the dilation width at the tracheal anterior wall incision; and a dilation degree marking structure 6, provided on the platform 1, for indicating the dilation width. The active channel 2 is not only used for the installation of two expansion plates, but also leaves an area in the center of the device for instruments to be inserted and moved. With the platform 1 as the main body, it is equipped with a fixed expansion plate 3 and a movable expansion plate 4 that can be controlled by the expansion switch 5 to expand the tracheal anterior wall incision as needed. The expansion operation is intuitive and clear. With the expansion degree marking structure 6 set on the platform 1, the expansion width at the tracheostomy can be observed in real time.

[0034] As one type of detachable and fixed installation, in this embodiment, a fixing groove 7 is provided on the platform 1, and an outer edge fixing boss 8 is provided on the side of the fixed expansion piece 3 facing away from the movable expansion piece 4. The outer edge fixing boss 8 is adapted to be inserted into the fixing groove, and the fixed expansion piece 3 is detachably fixed in the fixing groove 7 by fasteners. For example, matching threaded holes can be provided on the fixing groove 7 and the outer edge fixing boss 8 of the platform 1, and the fixed expansion piece 3 can be fixed on the platform 1 by screws.

[0035] Preferably, in this embodiment, the transverse cross-section of the main body of both the fixed dilatation piece 3 and the movable dilatation piece 4 is semi-annular. When in contact, the main bodies of the fixed dilatation piece 3 and the movable dilatation piece 4 form a cylindrical shape. This cylindrical shape allows for a guidewire insertion channel, and the semi-annular design makes the outer edge of the dilatation piece smoother, reducing damage to the patient's surgical site during operation. The bottom ends of both the fixed dilatation piece 3 and the movable dilatation piece 4 are semi-trumpet-shaped. When in contact, the bottom ends of the fixed dilatation piece 3 and the movable dilatation piece 4 form a trumpet shape, wider at the top and narrower at the bottom. This allows for instrument channeling while expanding the anterior tracheal wall incision outwards. The tapered shape facilitates efficient insertion into the anterior tracheal wall incision, improving dilation efficiency.

[0036] As one of the linear reciprocating motion installation designs, the platform 1 is provided with a linear slide rail 9. In this application, there are two linear slide rails 9, both of which are stepped groove structures on the platform 1. A linear slide bar 10 is provided on the side of the moving expansion plate 4 away from the fixed expansion plate 3. The linear slide bar 10 is adapted to slide on the linear slide rail 9.

[0037] As one design embodiment, the air-cutting expansion device of this application can be manually adjusted. In this example, the expansion switch 5 is a rotary handle, which is connected to the moving expansion plate 4 via a gear transmission structure. The gear transmission structure includes a gear 11 rotatably mounted on the platform 1 and a rack 12 mounted on the linear slide bar 10 and meshing with the gear 11. The rotary handle is fixedly connected to the gear 11 via a rotating rod. In this embodiment, the exemplary design is a single-gear, single-sided rack design. In other feasible designs, a double-gear transmission, double-sided rack design can also be used to make the adjustment operation smoother.

[0038] Preferably, the expansion mark structure 6 is a width gradation line extending along the linear sliding direction of the movable expansion piece 4 on the stage. In other feasible designs, the expansion mark structure 6 can also be a single width ruler mounted on the stage 1. Real-time and accurate monitoring of expansion data via the width gradation line or width ruler results in labor-saving, stable, and highly controllable operation, with precise parameter adjustments that are less likely to cause patient injury.

[0039] According to one example of this utility model, a guide seat 13 is detachably mounted on the platform 1. The guide seat 13 has a guide hole 14 in the middle. The movable expansion piece 4 is provided with at least one guide rod 15 extending in the same direction as the movable expansion piece 4 for passing through the guide hole 14. The guide design can restrict the movement of the movable expansion piece 4 and prevent the movable expansion piece 4 from falling off the track during sliding.

[0040] In other extended designs, the device can also be designed to be integrated with an instrument fixation bracket for mounting on an operating table, so that the stage 1 can be detachably fixed to the instrument fixation bracket. Furthermore, the instrument fixation bracket can be a multi-degree-of-freedom, multi-directional adjustable bracket.

[0041] As another feasible design, the tracheostomy dilation device of this application can also be electrically controlled. A motor connected to the moving dilation plate 4 via a transmission structure (such as gear transmission, or a common motor transmission structure such as an electric push rod) is mounted on the stage 1. The dilation degree marking structure 6 is adapted to be a display screen connected to the motor. The display screen can be electrically connected to the motor controller or wirelessly connected. The dilation switch 5 (which can be a button, knob, push button, or a virtual switch on the display screen) is connected to the motor to control its start / stop, rotation direction, torque magnitude (using a torque sensor connected to the motor output shaft to monitor the torque magnitude in real time), and motor stroke, which are displayed on the display screen. In other feasible designs, the dilation switch 5 can also be a wireless control device such as an infrared remote control, allowing remote operation of the motor, optimizing the operation method and improving ease of use. The display screen provides relevant important parameters in real time, reducing the difficulty of practical operation, saving doctors' energy, and improving surgical efficiency.
