Description

Technical Field

[0001] The utility model relates to a telescopic bronchial double-lumen cannula joint. Background Art

[0002] In thoracic surgery, double-lumen endobronchial tubes are the most widely used and mature products in clinical practice. The Y-connector is a key component of double-lumen endobronchial tubes, connecting them to the breathing circuit to continuously deliver gas to the patient. Currently, in thoracic surgery, if single-lung ventilation is required, hemostat clamps are typically used to clamp one side of the tube, preventing ventilation. However, thoracic surgery is not limited to single-lung ventilation; bilateral closure is sometimes required, requiring two hemostat clamps. If they are not clamped tightly, air leaks will occur, and the coordinated operation requires two people, which is both risky and wasteful.

[0003] There are also manufacturers on the market that have made improvements to the Y-type connector, placing the adjustment structure on the hoses on both sides for adjustment. Although this abandons the operation method of traditional hemostatic forceps, it is also relatively complicated in actual operation, and it is necessary to confirm the open / close status of the adjustment structure separately before operating them separately. Utility Model Content

[0004] The utility model aims to provide a telescopic bronchial double-lumen cannula joint, which is used to solve the problem of complicated operation when the bronchial double-lumen cannula needs unilateral lung ventilation or bilateral lung closure during thoracic surgery.

[0005] In order to solve the above problems, the technical solution of the utility model is:

[0006] A telescopic bronchial double-lumen cannula joint, the double-lumen cannula joint includes a three-way joint, the three-way joint includes three pipes, the two upper end pipes of the three-way joint are connected to the two hammer-shaped joints respectively through two ventilation pipes, and the other lower end pipe is connected to the machine end pipeline. A telescopic switching valve is provided on the double-lumen cannula joint.

[0007] The telescopic switching valve includes a sleeve arranged in a hammer-shaped joint, a first vent hole is opened on the sleeve, one end of the hammer-shaped joint is an opening, a sealing cover is buckled on the opening, a sliding groove is opened on the sealing cover and the sleeve, a slider is provided in the sliding groove, and one end of the slider is fixedly connected to the sleeve.

[0008] A slider locking opening is provided on the sealing cover sliding groove.

[0009] The telescopic switching valve includes a partition arranged in the three-way joint, which divides the three-way joint into two cavities. The two cavities are respectively connected to the two upper end pipes, and the two cavities are connected to the lower end pipes through branches. A pressing block is provided in the cavity, and a second vent is provided on the pressing block.

[0010] The beneficial effects of the utility model are as follows: the patent replaces the need to rely on hemostatic forceps to open / close the airway during thoracic surgery. The mechanism of the patent can be operated with one hand, and one person can complete the airway opening / closing operation. The patent is simple and practical to operate, and the effect of closing the airway is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] A telescopic bronchial double-lumen cannula joint, the double-lumen cannula joint comprising a tee joint 1, the tee joint 1 comprising three pipes, the two upper end pipes 2 of the tee joint 1 being connected to two hammer-shaped joints 7 respectively through two ventilation pipes 3, and the other lower end pipe 11 being connected to the machine end pipeline, a telescopic switching valve being provided on the double-lumen cannula joint.

[0019] Example 1:

[0020] The telescopic switching valve includes a sleeve 8 disposed within a hammer joint 7, with a first vent hole 15 defined in the sleeve 8. One end of the hammer joint 7 is open, with a sealing cap 4 fastened to the opening. A sliding groove 6 is defined between the sealing cap 4 and the sleeve 8, and a slider 5 is disposed within the sliding groove 6. One end of the slider 5 is fixedly connected to the sleeve 8. The slider 5 can push the sleeve 8 to move axially within the hammer joint 7, so that the first vent hole 15 and the pipe of the hammer joint 7 coincide or stagger, allowing the sleeve 8 to function as a "valve."

[0021] A locking opening 9 is provided on the sliding groove 6 of the sealing cover 4. After the slider 5 enters the locking opening 9, the locking opening 9 limits the sleeve 8 to avoid the situation where the sleeve 8 accidentally drops.

[0022] The working principle of Example 1 is as follows: in thoracic surgery using a double-lumen bronchial tube, the two sleeves 8 are extended and retracted along the slide groove 6 to achieve unilateral ventilation, bilateral ventilation or closed ventilation of the three-way connector 1.

[0023] like Figure 1 and 2 As shown, when the left sleeve 8 is at the lowest position of the slide groove 6 and the right sleeve 8 is at the highest position of the slide groove 6, the first vent hole 15 of the left sleeve 8 coincides with the pipe of the left hammer joint 7, and the first vent hole 15 of the right sleeve 8 is staggered with the pipe of the right hammer joint 7, thereby realizing left bronchial ventilation.

[0024] When the right sleeve 8 is at the lowest position of the slide groove 6 and the left sleeve 8 is at the highest position of the slide groove 6, the first vent hole 15 of the right sleeve 8 coincides with the right hammer joint 7 pipe, and the first vent hole 15 of the left sleeve 8 is staggered with the left hammer joint 7 pipe, thereby realizing right bronchial ventilation.

[0025] When the left sleeve 8 is at the lowest position and the right sleeve 8 is at the lowest position, the first vent hole 15 of the left sleeve 8 coincides with the pipe of the left hammer joint 7, and the first vent hole 15 of the right sleeve 8 coincides with the pipe of the right hammer joint 7, realizing bilateral ventilation.

[0026] When the left sleeve 8 is at the highest position of the slide groove 6 and the right sleeve 8 is at the highest position of the slide groove 6, the first vent hole 15 of the left sleeve 8 is staggered with the first vent hole 15 of the left hammer joint 7, and the first vent hole 15 of the right sleeve 8 is staggered with the first vent hole 15 of the right hammer joint 7, thereby achieving bilateral closure.

[0027] Example 2:

[0028] Embodiment 2 provides another switching valve body structure. The telescopic switching valve includes a partition 13 disposed within a tee connector 1. The partition 13 divides the tee connector 1 into two cavities. The two cavities are respectively connected to two upper end pipes 2. The two cavities are connected to the lower end pipe 11 through a branch pipe 12. A pressing block 10 is disposed within the cavity, and a second vent hole 14 is provided on the pressing block 10. By extending and retracting the pressing block 10, the second vent hole 14 is connected or disconnected with the upper end pipe 2 and the branch pipe 12 in the cavity, thereby enabling the pressing block 10 to function as a "valve."

[0029] The working principle of implementation 2 is that, in thoracic surgery using a double-lumen endobronchial tube, unilateral ventilation, bilateral ventilation or closed ventilation of the multifunctional joint can be achieved by pressing the left pressing block 10 and the right pressing block 10 .

[0030] like Figure 3 and 4 As shown, when the left pressing block 10 is pressed down and the right pressing block 10 is at the highest position, the second vent hole 14 of the left pressing block 10 is staggered with the upper end pipe 2 and the branch pipe 12 on the left side of the tee joint 1, and the second vent hole 14 of the right pressing block 10 is overlapped with the upper end pipe 2 and the branch pipe 12 on the right side of the tee joint 1, thereby realizing right bronchial ventilation.

[0031] When the right pressing block 10 is pressed down and the left pressing block 10 is at the highest position, the second vent hole 14 of the right pressing block 10 is staggered with the upper right end pipe 2 and the branch pipe 12 of the tee joint 1, and the second vent hole 14 of the left pressing block 10 is overlapped with the upper left end pipe 2 and the branch pipe 12 of the tee joint 1, thereby realizing left bronchial ventilation.

[0032] When both the left pressing block 10 and the right pressing block 10 are pressed down, the second vent hole 14 of the left pressing block 10 is staggered with the left upper end pipe 2 and the branch pipe 12 of the tee joint 1, and the second vent hole 14 of the right pressing block 10 is staggered with the right upper end pipe 2 and the branch pipe 12 of the tee joint 1, thereby achieving double-sided closure.

[0033] When the left pressing block 10 and the right pressing block 10 are both in the highest position, the second vent hole 14 of the left pressing block 10 coincides with the upper left end pipe 2 and the branch pipe 12 of the tee joint 1, and the second vent hole 14 of the right pressing block 10 coincides with the upper right end pipe 2 and the branch pipe 12 of the tee joint 1, thereby realizing bilateral ventilation.

[0034] 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 regarded as 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.
