Description

External cutter for suture cutting of drainage tube

Technical Field

The utility model belongs to the technical field of surgical auxiliary medical equipment, and particularly relates to an external cutter for suture cutting of a drainage tube.

Background

The drainage tube is a drainage device which is placed in an operation area and is used for discharging seepage possibly existing in the operation area to the outside after the operation, so that infection in the operation area is reduced or avoided.

The drainage tube is generally placed in the wound or subcutaneous tissue beside the wound while the operation is completed, and the purpose of placing the drainage tube is as follows: 1. preventing infection caused by accumulation of body exudates. 2. Abscess cavities are formed by internal infection, and a drainage tube is usually arranged after drainage is cut, so that residual infection liquid is led out, and wound artifact healing is prevented. 3. Is to monitor the occurrence of anastomotic leakage. 4. Post-luminal bleeding was monitored. 5. Wound wounds are generally contaminated wounds, and post-operative drainage tubes prevent bacterial and other contaminant accumulation leading to infection.

When suture operation is carried out after the drainage tube is placed, occasionally, a suture which is mistakenly sewn on the wall of the drainage tube but does not pass through the lumen cannot be smoothly pulled out on schedule, if the mistaken suture of the drainage tube occurs, an unintended secondary operation is required to be carried out, unnecessary damage is caused to a patient, and potential medical disputes risks exist, so that special instruments are required to be used for cutting the suture which is mistakenly sewn on the lumen of the drainage tube, secondary damage to the patient is avoided, and the potential medical risks are avoided.

Disclosure of Invention

In order to solve the technical problems, the technology of the utility model adopts the following technical scheme:
