Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a tracheal intubation guide wire. Background Art
[0002] A tracheal intubation guidewire is an instrument used to assist in tracheal intubation. It can help doctors accurately place the tracheal tube into the patient's trachea. In the treatment of respiratory diseases, tracheal intubation guidewires are widely used. During surgery, doctors need to use the tracheal intubation guidewire to guide the tracheal tube into the patient's trachea. This can ensure that the patient's airway is unobstructed, and the supply of oxygen and the discharge of carbon dioxide are guaranteed, thereby maintaining the patient's respiratory function. The existing tracheal intubation guidewire needs to be continuously inserted and pulled out during the process of inserting the tracheal tube, and the medical staff needs to continuously bend the guidewire to a suitable curvature to ensure that the tracheal intubation guidewire can accurately place the tracheal tube in the patient's trachea. In the process of placing and adjusting the guidewire, the medical staff needs to hold one end of the guidewire and slowly insert the guidewire with the other hand. However, because the guidewire is thin, it is easy to shake during the insertion process and after the position is determined, causing a certain position deviation, which affects the accuracy of tracheal intubation insertion. Utility Model Content
[0003] The utility model aims to solve the problem in the prior art that the guide wire is too thin and inconvenient to insert, remove and fix, and proposes a tracheal intubation guide wire.
[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:
[0005] The top end of the planetary gear is fixedly connected to the top of the gear train, and the top of the planetary gear is rotatably connected to the top of the gear train, and the bottom end of the planetary gear is fixedly connected to the top of the gear train.
[0006] Furthermore, the guide wire body passes through the guide wire sleeve and the knob, and one end of the guide wire body is detachably connected to a control handle.
[0007] Furthermore, a plurality of planetary gears are provided, and the planetary gears are distributed in an array around the circumference of the through pipe.
[0008] Furthermore, the bottom end of the rubber pad is higher than the top of the guide wire body.
[0009] Furthermore, each of the rubber pads has an arc-shaped structure.
[0010] The beneficial effects of the utility model are as follows:
[0011] The utility model facilitates the wire guide body to pass through the through tube, and then turns the knob to drive the gear ring to rotate through the connecting rod, and the gear ring drives each planetary gear to rotate. The rotation of the planetary gear causes the connecting block on the rotating rod to rotate synchronously, and the clamping rod on the connecting block rotates synchronously, and the clamping rod drives the rubber pad to aggregate, thereby clamping and fixing the wire guide body. After the wire guide body is installed and fixed, the wire guide sleeve can be fixed, thereby facilitating the limitation of the wire guide body, and further facilitating the insertion, removal and fixation of the wire guide body, so that the wire guide body will not be displaced a large distance after the position is determined, thereby meeting people's usage needs.

DETAILED DESCRIPTION
[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0017] like Figure 1-3As shown, a tracheal intubation guidewire is provided. In order to facilitate the fixation of the guidewire body 1 and facilitate the grasping and pulling out, the guidewire body 1 is provided. The outer wall of the guidewire body 1 is detachably connected to the guidewire sleeve 2. The top of the guidewire sleeve 2 is rotatably connected to the knob 3. The tightness of the guidewire body 1 is adjusted by rotating the knob 3. The guidewire sleeve 2 is provided with a locking adjustment mechanism 5. The locking adjustment mechanism 5 includes a through tube 51. The bottom end of the through tube 51 is fixedly connected to the inner bottom wall of the guidewire sleeve 2. The outer wall of the through tube 51 is fixedly connected to a support plate 52. The support plate 52 The top end is rotatably connected to a ring gear 53, and a connecting rod 54 is fixedly connected between the ring gear 53 and the knob 3. The outer wall of the through tube 51 is coaxially rotatably connected to the sun gear 511, and a planetary gear 55 is meshed and transmitted between the sun gear 511 and the ring gear 53. A rotating rod 59 is rotatably connected to the support plate 52, and the planetary gear 55 is coaxially and fixedly connected to the rotating rod 59. A connecting block 56 rotatably connected to the rotating rod 59 is provided on the top side of the planetary gear 55. A clamping rod 57 is fixedly connected to the outer wall of the connecting block 56, and a rubber pad 58 is fixedly connected to one end of the clamping rod 57.
[0018] Specifically, when in use, first pass the guide wire body 1 through the guide wire sleeve 2 and the knob 3, adjust the guide wire sleeve 2 to a suitable position, and then turn the knob 3. The knob 3 drives the connecting rod 54 to rotate, and the connecting rod 54 drives the ring gear 53 to rotate, and the ring gear 53 drives each planetary gear 55 to rotate. The rotation of the planetary gear 55 causes the connecting block 56 on the rotating rod 59 to rotate synchronously, and the clamping rod 57 on the connecting block 56 rotates synchronously, and the clamping rod 57 drives the rubber pad 58 to aggregate, thereby clamping and fixing the guide wire body 1. In order to ensure the stability of the rotation of each planetary gear 55, a sun gear 511 is set to rotate in coordination to assist the rotation of each planetary gear 55. After the guide wire body 1 is limited, the medical staff can hold the guide wire sleeve 2 to complete the insertion and removal of the guide wire body 1, increase the contact area, and prevent the guide wire body 1 from slipping out during the insertion and removal adjustment process. The setting of the rubber pad 58 effectively avoids damage to the clamping part.
[0019] like Figure 1-3 As shown, in some embodiments, the guidewire body 1 passes through the guidewire sleeve 2 and the knob 3, and one end of the guidewire body 1 is detachably connected to a control handle 4, which facilitates the control of the movement of the guidewire body 1 and prevents the guidewire body 1 from falling completely into the endotracheal tube.
[0020] like Figure 1-3 As shown, in some embodiments, a plurality of planetary wheels 55 are provided, and the planetary wheels 55 are distributed in a circular array about the through tube 51. The provision of multiple planetary wheels 55 facilitates multi-directional wrapping and clamping of the guide wire body 1.
[0021] like Figure 1-3As shown, in some embodiments, the bottom end of the rubber pad 58 is higher than the top end of the guidewire body 1. By setting the height of the rubber pad 58, it is ensured that the rubber pad 58 can stably clamp the outer wall of the guidewire body 1, thereby ensuring the position of the guidewire body 1.
[0022] like Figure 1-3 As shown, in some embodiments, each rubber pad 58 is an arc-shaped structure. Through the shape design of the rubber pad 58, the rubber pad 58 can fit the outer wall of the guide wire body 1 more closely, thereby enhancing the stability of clamping the guide wire body 1.
[0023] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
