Anti-secondary trauma endoscopic thyroid special hook

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an anti-secondary trauma endoscopic thyroid special hook. The hook comprises a hand lever and a hook head. The hook head comprises a first straight rod, a second straight rod and a third straight rod. A movable gap facilitating puncture action of the third straight rod is arranged between the third straight rod and the first straight rod. The first straight rod, the second straight rod and the third straight rod are matched to form the triangular supporting surface, and the triangular supporting surface and the hand lever are arranged in the intersection mode. The straight rods are hollow tubes with the tube cavities connected in sequence, the tube cavities of the straight rods extend up alonga hand lever body and communicated with negative suction holes formed in the hand lever. The hook further includes a cutting nail, and the cutting edge of the head of the cutting nail stretches out ofthe top end of the third straight rod. By means of the hook, secondary trauma can be effectively avoided during an operation while the thyroid lesion is fully exposed, and the special hook has the advantages of large endoscopic scope, good flexibility and convenient visual field.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a secondary-trauma-proof laparoscopic thyroid special retractor. Background technique [0002] In recent years, in the field of surgical treatment of thyroid diseases, laparoscopic thyroid surgery has been gradually used in clinics at home and abroad because of its advantages such as small and concealed incisions, and no scars in the neck after surgery. In conventional open thyroid surgery, the exposure of the surgical field is very critical. For this reason, the anterior neck muscles located in front of the thyroid gland must be used to expose the lesion as much as possible and facilitate viewing with the speculum. However, in laparoscopic surgery, if laparoscopic forceps are used to pull the anterior cervical muscles, more laparoscopic incisions need to be added, and the instruments will block part of the laparoscopic field of view during the operation, affe...

Problems solved by technology

In view of this, the utility model name of the Chinese patent announcement number "CN 202489985U" is "thyroid retractor for endoscopy" and the utility model name of the Chinese patent announcement number "CN 206518571U" is "a retractor for endoscopic thyroid surgery". All correspondingly provide a kind of draw hook structure, and its main body all comprises hook head and draw hook connecting rod, and problem is: one, when carrying out laparoscopic thyroid surgery, there are inevitably problems such as bleeding, and a large amount of blood deposits in the operation point area, to The interference of the surgical field is great, which brings many troubles to the actual operation

The use of auxiliary instruments such as scalpels will lead to additional operation preparation time, affecting the length of the operation, and it is difficult to control the depth of the incision

However, the use of the retractor with its own sharp tip obviously only considers the preoperative puncture and does not consider the use during the operation.
