Abstract
The utility model discloses a recurrent laryngeal nerve separates pincers for thyroid surgery, including two through the mutual articulated tong arm of pivot, tong arm tail end rigid coupling has integrated into one piece's ring, its characterized in that: the front end rigid coupling of tong arm have with the integrative separation head that takes shape of tong arm, the preceding terminal surface of separation head with contained angle between the tong arm is 120-160, and the recurrent laryngeal nerve holding tank has been seted up to the inboard of separation head, the recurrent laryngeal nerve holding tank sets up relatively, and the recurrent laryngeal nerve separating tank is on a parallel with the preceding terminal surface of separation head. The utility model discloses can look for and isolate recurrent laryngeal nerve fast at the thyroid surgery in -process, alleviate the neighbouring organ of blood vessel, trachea and esophagus and recurrent laryngeal nerve or the damage of tissue, guarantee going on smoothly of thyroid surgery.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of recurrent laryngeal nerve elastic separating plier for thyroid operation.
Background technology
Recurrent laryngeal nerve is out of shape near trachea and esophageal groove, and it finds with being separated is the bottleneck restricting thyroid operation process always.Fast searching recurrent laryngeal nerve, avoids damaging the unremitting pursue that the important organ such as trachea, esophagus is each Thyroid Surgery doctor simultaneously.
At present, when doing thyroid operation, finding and with the method being separated recurrent laryngeal nerve be: adopt vascular forceps to be separated at trachealgia ditch and find, easily causing blood vessel injury to cause hemorrhagely affects the visual field, if blindly clamp stops blooding, more easily causes the damage of recurrent laryngeal nerve; The head end of vascular forceps is comparatively easily sharp-pointed, and excessive searching is separated and easily damages esophagus, trachea thus cause esophageal fistula, tracheal fistula; Sometimes recurrent laryngeal nerve is close to tracheal wall or esophageal wall, needs to mention and differentiated, normal tissue pincers can not effectively and nondestructively clamp recurrent laryngeal nerve, easy landing; Current state-of-the-art way can rely on recurrent laryngeal nerve survey meter to find, but finally still needs to use apparatus anatomy of recurrent laryngeal nerve to be dissociated to be identified, and recurrent laryngeal nerve survey meter price is between 4000-5000 unit, and the financial burden of patient is heavier.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of recurrent laryngeal nerve elastic separating plier for thyroid operation, can in thyroid operation process, find rapidly and isolate recurrent laryngeal nerve, alleviate the damage of the organ or tissue of blood vessel, trachea and esophagus and recurrent laryngeal nerve vicinity, ensure carrying out smoothly of thyroid operation.
To achieve these goals, technical solution adopted in the utility model is: a kind of recurrent laryngeal nerve elastic separating plier for thyroid operation, comprise two tong arms be hinged by rotating shaft, tong arm tail end is connected with integrated finger ring, the front end of described tong arm is connected with the separating head integrally formed with described tong arm, angle between the front end face of described separating head and described tong arm is 120 ° ~ 160 °, the inner side of separating head offers recurrent laryngeal nerve holding tank, described recurrent laryngeal nerve holding tank is oppositely arranged, and recurrent laryngeal nerve separating tank is parallel to the front end face of described separating head.
Further, described rotating shaft is positioned at described tong arm front end 2/5 place, and the distance between described recurrent laryngeal nerve holding tank and the front end face of described separating head is 0.5mm ~ 1mm.
Further, two described recurrent laryngeal nerve holding tanks are oppositely arranged and bottom land profile is positioned on same ellipse.
Further, the width of described separating head broadens from back to front gradually, and the front end of separating head is blunt nosed.
The beneficial effect adopting technique scheme to produce is: the angle between the front end face of described separating head of the present utility model and described tong arm is obtuse angle, during with normal attitude hand-held elastic separating plier, the front end face of separating head is in level, be convenient to tissue and the organ of pushing recurrent laryngeal nerve periphery aside, the front end of separating head is blunt nosed, can effectively avoid piercing tissue and organ, recurrent laryngeal nerve parcel can also be separated rapidly by recurrent laryngeal nerve holding tank, in thyroid operation process, be convenient to find rapidly and isolate recurrent laryngeal nerve, and reduce blood vessel, the injury of the organ or tissue that trachea and esophagus etc. are contiguous with recurrent laryngeal nerve, ensure carrying out smoothly of thyroid operation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is front view of the present utility model.
Fig. 2 is the enlarged drawing of this utility model elastic separating plier front end.
The inner side view of this utility model tong arm and separating head during Fig. 3.
In figure: 1, tong arm 2, finger ring 3, rotating shaft 4, separating head 5, recurrent laryngeal nerve holding tank.
Detailed description of the invention
Referring to attached Fig. 1 and 2, the structure of this utility model detailed description of the invention comprises two tong arms 1 be hinged by rotating shaft 3, tong arm 3 tail end is connected with integrated finger ring 2, the front end of described tong arm 1 is connected with the separating head 4 integrally formed with described pincers 1, angle between the front end face of described separating head 4 and described tong arm 1 is 145 °, the inner side of separating head 4 offers recurrent laryngeal nerve holding tank 5, described recurrent laryngeal nerve holding tank 5 is oppositely arranged, and recurrent laryngeal nerve separating tank 5 is parallel to the front end face of described separating head 4.
Described rotating shaft 3 is positioned at described tong arm 1 front end 2/5 place, and the distance between described recurrent laryngeal nerve holding tank 5 and the front end face of described separating head 4 is 0.5mm.This design proportion can mate operating environment during thyroid operation preferably.
Two recurrent laryngeal nerve holding tanks 5 are oppositely arranged and bottom land profile is positioned on same ellipse.When tong arm 1 clamps, recurrent laryngeal nerve can wrap up and fix by recurrent laryngeal nerve holding tank 5, be convenient to be separated recurrent laryngeal nerve, in addition, when separating head 4 closes, there is gap in the lower limb of two recurrent laryngeal nerve holding tanks 5, enables thicker recurrent laryngeal nerve get into gap, avoids the damage caused because extruding recurrent laryngeal nerve by force.
The width of described separating head 4 broadens from back to front gradually, and the front end of separating head 4 is blunt nosed.The particular design of separating head 4 is convenient to peel off the tissue around recurrent laryngeal nerve and organ with no damage more.
Operation principle of the present utility model is: during thyroid operation, expose and free thyroid after, be a bit in plexas thyreoidea inferior position with thyroid and trachea sidewall junction, adopt tissue forceps respectively to upper, tractive parathyroid tissue laterally, expose the triangle deathtrap that recurrent laryngeal nerve is out of shape, re-use recurrent laryngeal nerve elastic separating plier of the present utility model, be separated forward along trachealgia ditch by separating head 4, be easy to find recurrent laryngeal nerve.
After finding recurrent laryngeal nerve, separating head 4 is inserted into recurrent laryngeal nerve both sides, then clamps tong arm 1, make recurrent laryngeal nerve be in two recurrent laryngeal nerve holding tanks 5, finally can easily recurrent laryngeal nerve be separated.
This utility model is more pointed compared with normal tissue pincers, can effectively avoid recurrent laryngeal nerve landing.
Foregoing description only proposes, not as the single restrictive condition to its technical scheme itself as the enforceable technical scheme of this utility model.
