Description

Scissors special for bronchoscope

Technical Field

The utility model relates to a special scissors of bronchoscope belongs to bronchoscope and assists medical instrument technical field.

Background

Foreign matter in the trachea is clinical common disease, and some foreign matters, like the fishbone, the shape is irregular and have the barb, can pierce through the ridge between the trachea, leads to taking out the difficulty, if adopt biopsy forceps directly to pull out then have the risk of tearing the trachea at present, adopt other modes also to have same difficulty, if have scissors to cut off the fishbone then can take out respectively to avoid open chest operation.

In addition, in patients who have undergone a lung sleeve resection, after the incision anastomosis, the suture is sometimes exposed in the trachea, and the suture exposed in the trachea adheres to adhesive secretions and also hinders the discharge of distal secretions, which is more common particularly in the case of anastomotic stenosis. These exposed sutures could theoretically be cut off 3 months after surgery, but there is currently no instrument available for cutting off the sutures via an electronic bronchoscope.

In view of the above, we propose to invent a special scissors that can be used with an electronic bronchoscope to solve the above problems.

Disclosure of Invention

The utility model discloses a solve the difficult problem that the suture that the interior foreign matter of trachea and expose is difficult to cut off and take out, provide a special scissors through using with the cooperation of electron bronchoscope.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a special scissors of bronchoscope which characterized in that: the scissors device comprises a handle, wherein a sliding handle is arranged on the handle, a spring tube is arranged below the handle, a scissors fixing seat is arranged at the end part of the spring tube, and scissors are arranged on the scissors fixing seat; the traction steel wire penetrates through the spring tube, one end of the traction steel wire is connected with the sliding handle, and the other end of the traction steel wire is connected with the scissors.

Preferably, the sliding handle is sleeved on the handle, and one end of the traction steel wire is fixed by the sliding handle through an internal wire fixing device.

Preferably, the scissors fixing seat is in a groove shape, and the scissors are fixed in the groove through a fixing pin shaft.

Preferably, the rear end of the scissors is connected with a Y-shaped connecting rod, and the traction steel wire is connected with the Y-shaped connecting rod.

Preferably, the scissors are cross-shaped, with the inside of the scissors being slightly curved.

Preferably, the spring tube is formed as a circular long tube from a wire spring.

Preferably, the sliding handle is dumbbell-shaped.

Preferably, the handle comprises a round hole thumb ring and a handle.

The utility model discloses special scissors of bronchoscope obtains following beneficial effect:

the pair of special scissors for the bronchoscope can solve the problems that foreign matters in the trachea can not be cut off and are difficult to take out, and exposed sutures in the trachea can not be cut off, avoids the problem that the problems can be solved only by a chest-open operation, has extremely high practical value and social value, can help to improve the treatment effect, and relieves the pain of patients and the treatment cost.

Drawings

Fig. 1 is a schematic view of the present invention.

Fig. 2 is a structure view of the scissors portion of the present invention.

In the figure:

1. the scissors comprise a handle, 2, a pin shaft, 3, a sliding handle, 4, a spring tube, 5, a traction steel wire, 6, a wire fixing device, 7, scissors, 8 and a scissors fixing seat.

Detailed Description

The invention will be further explained with reference to the drawings:

as shown in fig. 1-2, a pair of special scissors for bronchoscope is characterized in that: the scissors comprise a handle 1, wherein a sliding handle 3 is arranged on the handle 1, a spring tube 4 is arranged below the handle 1, a scissors fixing seat 8 is arranged at the end part of the spring tube 4, and scissors 7 are arranged on the scissors fixing seat 8; the traction steel wire 5 penetrates through the spring tube 4, one end of the traction steel wire 5 is connected with the sliding handle 3, and the other end of the traction steel wire is connected with the scissors 7.
