Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bronchoscope auxiliary tools, in particular to a hard bronchoscope sheath and a hard bronchoscope. BACKGROUND

[0002] The sheath is usually used in cooperation with an endoscope surgery system, and mainly functions to accommodate and protect the lens part of the endoscope, provide a channel for surgical instruments, and provide a stable support, so that the doctor can more accurately control the endoscope to perform fine observation and operation. It plays an important role in endoscopy and surgery.

[0003] However, the existing sheath mainly has the following problems:

[0004] 1) High endoscope damage rate: In current surgical operations, the endoscope and the probe of the laser and cryogenic equipment are in the same channel, which can easily cause damage to the head end of the endoscope;

[0005] 2) Poor intubation stability: In the existing single-layer sheath tube, the endoscope cannot be fixed, causing the surgical field to shake or rotate, and in clinical surgery, a full-time doctor is often needed to hold the endoscope;

[0006] 3) Low stent placement efficiency: Due to the structural design limitations of the existing sheath and the silicone stent placement device, the silicone stent cannot be placed under the mirror, and the doctor can only use the endoscope to determine the general lesion position, then remove the endoscope from the sheath, and then place the silicone stent placement device in the sheath to blindly push the silicone stent into the airway, and then insert the endoscope to adjust the position with the minimally invasive surgery forceps, causing the placement process to be unable to be guided by imaging;

[0007] 4) If the size of the sheath is not suitable for the silicone stent (the silicone stent cannot enter the sheath), the doctor may need to choose a suitable sheath, and the sheath is removed under general anesthesia to enter the suitable sheath again (second intubation), which increases the difficulty of anesthesia and increases the risk of surgery.

[0008] Therefore, it is an urgent problem for those skilled in the art to provide a safe and efficient hard bronchoscope sheath and hard bronchoscope. SUMMARY

[0009] Therefore, the present application provides a hard bronchoscope sheath and a hard bronchoscope, which are safe, stable and reliable, and improve the clinical work efficiency.

[0010] In order to achieve the above purpose, the present application adopts the following technical solutions:

[0011] A hard bronchoscope sheath comprises an inner sheath tube, and the inner sheath tube has a first channel for an endoscope lens tube to pass through and a second channel for instruments to pass through.

[0012] By adopting the above technical solutions, the application has the following beneficial effects:

[0013] By adopting the double-channel design, the endoscope mirror tube can be isolated from other devices and instruments during use, thereby ensuring the safety of the mirror tube and facilitating synchronous operation of the instruments to achieve guided placement of the silicone stent under the mirror.

[0014] Further, the inner sheath proximal end has a straight clamping groove matched with the buckle of the endoscope mirror joint.

[0015] The beneficial effect of adopting the above further technical solution is that the inner sheath and the endoscope mirror are clamped and fixed, and are not prone to rotation and sliding, thereby ensuring stability during surgical operation.

[0016] Further, the outer sheath is also included, and the inner sheath and the outer sheath are distributed inside and outside; the outer sheath proximal end has an L-shaped clamping groove matched with the buckle of the endoscope mirror joint.

[0017] The beneficial effect of adopting the above further technical solution is that, when the silicone stent is placed, secondary intubation is not required, the operation and anesthesia difficulty is reduced, and the inner sheath, the outer sheath and the endoscope mirror are clamped and fixedly connected, thereby ensuring stability.

[0018] Further, the inner sheath includes an inner sheath body and an inner sheath head connected as a whole, the inner sheath head has a larger diameter than the inner sheath body; the straight clamping groove is arranged on the inner sheath head; the outer sheath includes an outer sheath body and an outer sheath head connected as a whole, the outer sheath head has a larger diameter than the outer sheath body; the step surface of the inner sheath head abuts against the step surface of the outer sheath head; and the L-shaped clamping groove is arranged on the outer sheath head.

[0019] The beneficial effect of adopting the above further technical solution is that the inner sheath is prevented from falling out of the outer sheath.

[0020] A rigid bronchoscope includes the rigid bronchoscope sheath as described above.

[0021] Therefore, the application provides a rigid bronchoscope sheath and a rigid bronchoscope, and compared with the prior art, the application has the following beneficial effects:

[0022] 1) Improved positioning accuracy: guided placement and position adjustment of the silicone stent under the mirror are achieved;

[0023] 2) Ensure instrument stability: the endoscope and the mirror sheath are clamped and fixed, and are not prone to rotation or sliding;

[0024] 3) Protect the mirror body: multi-cavity structure facilitates synchronous operation of instruments and reduces damage to the mirror body by laser equipment;

[0025] 4) Reduce anesthesia difficulty: rigid mirror sheath is inserted once, avoiding anesthesia difficulty caused by multiple intubations;

[0026] 5) Easy to promote and train: standardized design takes into account existing endoscopic systems, and the operation method is the same as that of the existing rigid bronchoscope sheath, without the need for special clinical skill training for this design, facilitating clinical introduction.

[0045] In the implementation of silicone stent placement, endoscope body 3 and inner sheath 1 can be directly taken out of the patient's body, and the outer sheath 2 is left in the patient's body. The silicone stent can be directly placed in the front end of the inner sheath 1. After being placed, the endoscope body 3 and the inner sheath 1 are inserted into the outer sheath 2 for fixation. Under the guidance of endoscope, the silicone stent can be directly and accurately pushed into the lesion by minimally invasive forceps. If the silicone stent does not match the size of the inner sheath 1, the matching inner sheath 1 can be directly replaced.
