Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a telescopic mechanism for an endotracheal breathing intervention catheter. Background Technology

[0002] The guide sheath (GS), extending from the tip of the bronchoscope to the lesion in the peripheral lung, has been widely used as an extended working channel in the diagnosis of peripheral lung lesions under radial ultrasound bronchoscopy and navigation bronchoscopy. It simplifies the problem of repeated localization of biopsies, improves operational efficiency, and reduces operation time.

[0003] For example, Chinese patent CN217960048U discloses a bronchoscope navigation device, including a bronchoscope body, an inner component, and an outer component; the inner component is located at one end of the bronchoscope body and can extend into the bronchus along with the bronchoscope body; the outer component is located outside the human body, and the outer component and the inner component can attract each other; this bronchoscope navigation device has a simple structure, is easy to use, facilitates the adjustment of the bronchoscope angle, and reduces operation time.

[0004] This patent has the following problems:

[0005] Existing technologies present limitations in the retractable and extendable catheters used in endoscopic procedures. The catheters require constant hand gripping by the physician, reducing their ease of use within the endoscope. Furthermore, the catheters are not easily positioned, fixed, or used within the endoscope, thus compromising their stability during endoscopic installation. Therefore, we propose a retractable and extendable catheter mechanism for endoscopic respiratory intervention. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a telescopic mechanism for an endoscopic breathing catheter, thereby improving the ease of use of the catheter within an endoscope and enhancing the stability of its installation and use within an endoscope.

[0007] In view of this, the present invention provides a telescopic mechanism for an endotracheal breathing intervention catheter, including a slide rod tube, and further comprising: an adjusting knob sleeve fixedly sleeved on the outside of the slide rod tube, a threaded socket being provided around the outside of the adjusting knob sleeve, a handle tube movably sleeved on one side of the slide rod tube, a fixing knob sleeve being threadedly sleeved on the outside of the handle tube, a fixing knob threaded groove being provided around the inside of the fixing knob sleeve, and a fixing knob gripping groove being provided around the outside of the fixing knob sleeve.

[0008] Based on the above structure, by fixing the adjusting knob sleeve to the outside of the slide tube, and then using the through-hole socket on the outside of the adjusting knob sleeve for movable snap-fit ​​installation inside the endoscope, the catheter can be snapped in and installed inside the endoscope during use, thereby improving the convenience of catheter use and installation inside the endoscope. Then, by using the fixing knob sleeve and the inside of the handle tube, the slide tube can be extended and retracted in height. Then, by tightening the fixing knob sleeve by rotating the thread on the outside of the handle tube, the slide tube is damped and positioned inside the handle tube, allowing the catheter to be positioned and used after the angle is adjusted inside the endoscope. When the fixing knob sleeve is rotated less, the slide tube is damped and adjusted up and down inside the handle tube. When the fixing knob sleeve is rotated more, the slide tube is positioned inside the handle tube, thereby improving the stability of catheter installation and use inside the endoscope.

[0009] Preferably, the handle tube is internally fitted with a keel made of rubber, and the handle tube is externally fitted with an expansion connection knob sleeve.

[0010] Preferably, the inner circumference of the extension connection knob sleeve is provided with an extension knob threaded groove, and the outer circumference of the extension connection knob sleeve is provided with an extension knob gripping groove.

[0011] Preferably, the internal threads of the expansion knob threaded groove are fitted with an expansion connecting hose, which is made of rubber.

[0012] Preferably, the internal channel of the extended quick-release handle can be used to insert and remove external instruments, such as cameras, surgical instruments, etc.

[0013] The beneficial effects of this utility model are:

[0014] 1. The telescopic mechanism of this endotracheal respiratory intervention catheter is fixedly fitted to the outside of the slide rod tube by adjusting the knob. Then, the catheter is movable and snapped into place inside the endoscope by using the socket hole that is circumferentially set around the outside of the adjusting knob. This allows the catheter to be snapped into place inside the endoscope during use, so that the doctor does not have to hold the device all the time, thereby improving the convenience of catheter use and installation inside the endoscope.

[0015] 2. The telescopic mechanism of this endotracheal breathing intervention catheter allows for the vertical extension and retraction of the sliding tube through a fixed knob sleeve and the inside of the handle tube. Then, the fixed knob sleeve is tightened by rotating the threaded screw on the outside of the handle tube, providing damped positioning of the sliding tube inside the handle tube. This allows the catheter to be positioned and used after being adjusted at the correct angle within the endoscope. A smaller number of rotations of the fixed knob sleeve allows for damped vertical adjustment of the sliding tube within the handle tube, while a larger number of rotations positions the sliding tube within the handle tube, preventing the catheter from wobbling during use and thus improving the stability of the catheter during installation and use within the endoscope.

[0033] In this embodiment, the extension connecting hose 6 can be threaded inside the extension knob threaded groove 501, thereby improving the stability of the installation.

[0034] Specifically, the conduit channel 1 is fixedly installed inside the slide rod pipe 2.

[0035] In this embodiment, the telescopic mechanism of an endotracheal breathing intervention catheter is used by adjusting the knob sleeve 201 to be fixedly fitted on the outside of the slide tube 2. Then, the sleeve 201 is movably engaged inside the endoscope using the through-hole 202. Next, the slide tube 2 is extended or retracted vertically using the fixed knob sleeve 3 and the handle tube 4. Then, the fixed knob sleeve 3 is tightened by rotating the threaded screw on the outside of the handle tube 4, providing damped positioning of the slide tube 2 inside the handle tube 4. Finally, the handle is used to... Tube 4 facilitates the gripping and operation of the catheter by medical staff. Then, the expansion knob threaded groove 501 facilitates connection and installation with other tubes. Next, the expansion connecting hose 6 is threaded inside the expansion knob threaded groove 501.
