Controllable guiding sheath tube capable of being inserted stably

Abstract

The invention provides a controllable guiding sheath tube capable of being inserted stably, and relates to the technical field of medical instruments, the controllable guiding sheath tube comprises a main body, the main body is of a cylindrical structure, and an inner groove is formed in the side wall of the main body; an open groove is formed in the side end of the inner groove, and side grooves outside the inner groove are formed in the two sides of the main body; the sliding plate is of a conical structure, and the sliding plate is installed on the outer side of the main body in a sliding mode; and the vertical plate is mounted at the bottom of the side end of the inner pipe in the main body. The sliding plate is placed at the part in contact with the skin of a patient, so that when the guiding sheath tube is inserted, the movement of the main body is guided, the main body stably moves during insertion, discomfort of the patient caused by shaking is prevented, and meanwhile, the situation that the hand is in contact with the outer side of the main body to cause bacterial infection is prevented; the problem that when an existing guiding sheathing canal is used, the portion, making contact with a patient, of the guiding sheathing canal shakes, and discomfort of the patient is likely to be caused is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stably inserted controllable guide sheath. Background technique [0002] The introducer sheath refers to a thin-walled tubular sheath consisting of a dilation tube, a sheath tube and a hemostatic valve, used to establish a catheter during endoscopic urological surgery, and a working channel to protect the ureter during repeated instrument changes. [0003] However, when the existing introducer sheath is in use, the sheath tube seat of the introducer sheath is made of plastic material and is fixed by its own elastic force, and the pressure applied during the use process is relatively large, which may easily cause the plastic material to break. In addition, when the guide sheath is inserted into the patient, the length of the guide sheath is relatively long, and the part in contact with the patient vibrates, which is likely to cause discomfort to the patient.

AI Technical Summary

Problems solved by technology

[0003] However, when the existing guide sheath is in use, the sheath seat of the guide sheath is made of plastic material and fixed by its own elastic force, and the pressure applied during use is relatively high, which may easily cause the plastic material to break. Moreover, when the guide sheath is inserted into the patient's body, the length of the guide sheath is relatively long, and the parts in contact with the patient vibrate, which may easily cause discomfort to the patient.
