Abstract
Description
Technical Field
[0001] The utility model relates to a bronchial blocking catheter with a variable front angle. Background Art
[0002] The angles formed by the extension lines of the left and right bronchi and the midline of the trachea are 35° and 25° respectively. Therefore, the front angle of the existing bronchial occlusion catheter is pre-shaped and fixed to 30°, which can meet the occlusion requirements under normal airway conditions (such as Figure 1 ), but when the right upper lobe opening is abnormal, higher than the carina (right main bronchus), and forms various angles with the main bronchus (such as Figure 2 ), the existing common occluding tube with a front end pre-formed angle of 30° has the following disadvantages: 1. The accuracy rate of one-time placement is low; 2. It is impossible to accurately occlude the abnormal opening of the right upper lobe and other areas with different angles. Utility Model Content
[0003] The utility model aims to provide a bronchial blocking catheter with a variable front angle, which is used to solve the problems of low one-time accuracy of existing bronchial blocking catheters and the inability to accurately block different angles such as abnormal opening of the right upper lung lobe.
[0004] In order to solve the above problems, the technical solution of the utility model is:
[0005] A bronchial blocking catheter with a variable front-end angle comprises a blocking catheter, which comprises a tube body, a blocking joint and a balloon. A wiring cavity is provided on the tube body, an adjustment wire is provided in the wiring cavity, a bending tube is provided at one end of the tube body close to the balloon, a wire pulling mechanism is provided at one end of the tube body close to the blocking joint, one end of the adjustment wire is connected to the wire pulling mechanism, and the other end passes through the bending tube and is fixedly connected to one end of the tube body.
[0006] The wire pulling mechanism comprises a pipe having one end connected to the wire routing cavity, a wire pulling cap is connected to the external thread of the pipe, and one end of the adjustment wire is fixedly connected to the wire pulling cap.
[0007] A stepped hole is arranged on the wire cap, a stepped shaft is arranged in the stepped hole, and one end of the adjusting wire is fixedly connected with the stepped shaft.
[0008] A plurality of anti-slip ridges are arranged outside the pull-wire cap.
[0009] A spring is arranged in the bending tube.
[0010] The beneficial effects of the utility model are as follows: the patent can accurately locate and block the left and right lungs, and can also accurately block the abnormal opening of the right upper lobe, the middle and lower lung segments, and other situations. The front end of the tube body is improved on the existing bronchial blocking catheter, and can be adjusted at an angle of 0-150°. The tube placement method is the same as that of an ordinary blocking catheter, the angle adjustment operation is simple, and the angle can be self-locking and rotated; the product can quickly fill the clinical gap in the field of abnormal opening of the right upper lobe and the middle and lower lung segments, solve industry problems, replace the existing ordinary occluders or front-end pre-bent angle occluders, reduce the patient's pain, and save doctors' operations.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] A bronchial blocking catheter with a variable front-end angle comprises a blocking catheter, which comprises a tube body 3, a blocking joint 6 and a balloon 2. A wiring cavity 31 is provided on the tube body 3, an adjustment wire 4 is provided in the wiring cavity 31, a bending tube 1 is provided at one end of the tube body 3 close to the balloon 2, a wire pulling mechanism 5 is provided at one end of the tube body 3 close to the blocking joint 6, one end of the adjustment wire 4 is connected to the wire pulling mechanism 5, and the other end passes through the bending tube 1 and is fixedly connected to one end of the tube body 3. The tube body 3 is a medical PVC hose, and the bending tube 1 is a medical silicone tube. The silicone tube is softer than the PVC hose, so the front end of the tube body 3 can be bent at the bending tube 1.
[0021] When in use, after the blocking catheter is inserted into the human bronchus, the angle of the front end of the tube body 3 is adjusted according to the actual insertion angle; during adjustment, the adjustment wire 4 is tightened and moved upward by the pull-wire mechanism 5, and a force is applied to the bending tube 1 at the front end of the tube body 3, so that the bending tube 1 is bent by 0-150°, thereby completing the purpose of adjusting the angle of the front end.
[0022] The wire pulling mechanism 5 includes a pipe 51 having one end connected to the wiring cavity 31, a wire pulling cap 53 being externally threadedly connected to the pipe 51, and one end of the adjustment wire 4 being fixedly connected to the wire pulling cap 53. Since the wire pulling cap 53 is threadedly connected to the pipe 51, when the wire pulling cap 53 is selected, the wire pulling cap 53 can pull the adjustment wire 4 to tighten, and can realize self-locking and rotation of the adjustment angle, and the structure is simple and easy to use.
[0023] A stepped hole is provided on the pull cap 53, and a stepped shaft 52 is installed in the stepped hole. One end of the adjustment wire 4 is fixedly connected to the stepped shaft 52. When the pull cap is rotated, the stepped shaft 52 will not rotate with the pull cap 53, thereby preventing the adjustment wire 4 from rotating, thereby preventing the adjustment wire 4 from rotating and twisting, and preventing the adjustment wire 4 from loosening or disconnecting due to rotation and twisting.
[0024] A plurality of anti-slip ridges 54 are provided outside the wire cap 53 .
[0025] A spring 7 is provided in the curved tube 1. The spring 7 is used to support the curved tube 1, and can ensure that the curved tube 1 will not be flattened when bent, so as not to affect the suction of phlegm during surgery.
[0026] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
