Needle holder for laryngeal micro-suture

Technical Field

The utility model belongs to the field of micro-suture instruments, in particular to a needle holder for laryngeal micro-suture under a supporting laryngoscope.

Background

Microsurgery is the fine surgical suture of fine tissues by a surgeon with the help of the magnification of a surgical microscope and using fine microsurgical materials; particularly, after a patient with laryngeal lesion of a supporting laryngoscope resects a laryngeal lesion tissue, a microscopic mucous membrane suture technology is adopted to perform intermittent suture on a mucous membrane wound edge after the lesion is resected; the healing time of the wound is short by adopting a microscopic mucosa suture technology, the sound is improved, the scar is reduced, and the adhesion is lightened;

when carrying out throat microsurgery under the support laryngoscope and sewing up, need use the needle holder to carry out the needle holding operation, but the antiskid concave tooth on the microsurgery needle holder binding clip that uses at present is horizontal distribution, and when the support laryngoscope that 23cm long diameter is about 3cm wide centre gripping suture needle carries out the microsurgery under the support laryngoscope and sews up the operation, the binding clip centre gripping suture needle of horizontal antiskid concave tooth is extremely unstable, and the needle body skids easily, and the doctor adopts the direction that the needle holder is difficult to control the syringe needle.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model designs a needle holder for laryngeal micro-suture, the clamping surface of the binding clip of the needle holder changes the existing anti-skid concave teeth distributed transversely into the anti-skid concave teeth distributed obliquely from 0 degree to 45 degrees; when the forceps head with the structure clamps the suture needle, the needle body can be kept stable and does not slip, so that the suture operation of doctors is facilitated;

in order to achieve the technical effects, the utility model discloses a realize through following technical scheme: a needle holder for laryngeal microsurgery comprising: the front handle, the front holding ring, the rear handle, the rear holding ring, the rear handle hinged part, the front handle hinged part, the tong rod, the lower tong head, the upper tong head brake rod core, the upper tong head, the front spring leaf and the rear spring leaf;

the lower end of the front handle is connected with the front holding ring, and the lower end of the rear handle is connected with the rear holding ring; the head end of the front handle is connected with the front handle hinged part, and the head end of the rear handle is connected with the rear handle hinged part; the front handle and the rear handle are hinged through a front handle hinge part and a rear handle hinge part; the head end of the rear handle hinged part is connected with the tail end of the clamp rod; the head end of the clamp rod is connected with the upper clamp head and the lower clamp head; the clamping surfaces of the upper tong head and the lower tong head are respectively provided with anti-skid concave teeth inclined at 0-45 degrees;

further, a front spring piece and a rear spring piece are connected between the front handle and the rear handle;

furthermore, an upper tong head braking rod core is connected in the tong rod, the head end of the upper tong head braking rod core is connected with the upper tong head, and the tail end of the upper tong head braking rod core is connected with the rear handle through a rear handle hinged part.

The utility model has the advantages that:
