Abstract

The utility model relates to tendon forceps of clinic surgery instrument, consisting of a head, a rod and a handle. The technical character of the utility model is: the upper and the lower jaws of the head are closed to be a spindle shape, and the arc of the lower jaw surface is slightly smaller than that of the upper jaw, facilitating the insertion of the head into the tendon forceps, and the tendon forceps is uneasy to be forced to be below the jaw; the upper and the lower jaws are respectively provided groove inside, and a plurality of cone teeth is arranged inside the groove; the sharp of the cone teeth is slightly higher than the plane of the groove; the upper and the lower tooth sharps are opposite and slightly staggered, so that the jaws is easy to clip the tendon; when the jaws are not in the clamp of the tendon and are closed, no gap is left, therefore, the surrounding tissue is uneasy to be clipped. The closed forceps head can be designed into a plurality of specifications according to the closed diameter, so that the utility model is suitable for different patients with different tendon. The tendon forceps has simple operation, fast speed and firm tendon clamping in the clinic operation; the tendon and the tendinous sheath are not easy to be damaged. The tendon forceps has popularization value in clinic surgery.

Description

Tendon forceps

Affiliated technical field

This utility model relates to a kind of hands surgical clinical operating theater instruments Tendon forceps.

Background technology

Seek tendon in the hands surgical operation at present, the general mosquito forceps of using is sought in stndon sheath and the clamping tendon, because of mosquito forceps is difficult for opening in stndon sheath, be difficult to find out the tendon broken ends of fractured bone, easily the tendon broken ends of fractured bone is pressed to the first limit of mosquito forceps, more difficult finding and the clamping tendon easily clips broken stndon sheath, even the nervus vasculairs around the damage, time-consuming, effort, damage are big.Sometimes must do otch in addition, seek tendon.If major injury appears in mosquito forceps retaining part tendon, just must excise, otherwise occur adhesion of tendon easily.

Summary of the invention

The purpose of this utility model is intended to improve the deficiency of existing hands surgical operating instrument, use for reference the construction features of department of otorhinolaryngology laryngeal polypus forceps, in conjunction with the operating specific requirement of hands, improve design, succeed in developing that a kind of clinical practice damage is little, speed fast and the novel Tendon forceps in clamping jail.

The technical solution of the utility model is as follows:

Novel Tendon forceps is made up of binding clip, claw beam and pincers handle three parts.

Binding clip contains upper jaw, lower jaw and the axis of guide, and upper jaw tail end and axis of guide front end and lower jaw stage casing are flexibly connected by bearing pin respectively, and axis of guide rear end and lower jaw tail end fairlead are slidingly matched.

The pincers handle divides forward and backward handle, and the bullet shape steel disc that supports its folding is arranged at the bottom between the two, and the middle part is provided with the button that closes of its folding angle of location.

Claw beam comprises sleeve pipe, inner guide wire and swivel nut, and the sleeve pipe front end is threaded with binding clip lower jaw tail end fairlead, and seal wire is threaded with the binding clip axis of guide, and the sleeve pipe rear end is connected by the screw tightening with pincers handle back handle front end.

The technical characterstic of this Tendon forceps is that the upper and lower jaw of binding clip is the spindle shape when closed, and lower jaw surface radian is smaller than the surperficial radian of upper jaw, is convenient to binding clip and enters stndon sheath, and is difficult for tendon is pressed to below the jaw; Each is fluted in the upper and lower jaw, be provided with some taper teeth in the groove, the taper crown is a little more than the groove plane, up and down crown respectively correspondence stagger a little, be convenient to jaw and hold the clamping tendon, not clamping of jaw tendon and when closed, seamless, surrounding tissue be difficult for to embed, binding clip during according to closure diameter can be made into plurality of specifications, the patient that suitable stndon sheath varies in size selects for use.

Three taper teeth that the upper and lower jaw inner groovy operated by rotary motion of binding clip is triangularly arranged.

The claw beam that is connected with binding clip should have bending, and depending on the circumstances or the needs of the situation, the crooked claw beam of record book in accordion form is convenient to binding clip and is changed direction, advances in stndon sheath.

Be provided with closing of its folding angle of location between the forward and backward handle of pincers handle and buckle clamping tendon difficult drop-off.The pincers handle closes the button front end and is connected with the front hand grip hinge, and the back handle notch is inserted in the rear end, closes the uniform saw of the face of buckling shape tooth, can support the location by spring leaf with tooth engagement on the back handle notch.

Operational approach: during operation, the handle of holding with a firm grip, handle promotes the axis of guide forward by inner guide wire, and upper jaw is rotated counterclockwise and closed around its bearing pin that is connected with lower jaw, and binding clip enters stndon sheath, push ahead, if be hampered power, then retreat binding clip a little, unclamp and close button, strut handle, by moving behind the inner guide wire pulling axis of guide, upper jaw is connected bearing pin around it with lower jaw and clockwise rotates, and jaw is opened, advance binding clip more forward a little, tendon can enter jaw, and handle clamps, and closes and buckles button, jaw steadily clips tendon, retreats to involve tendon.

This Tendon forceps clinical operation application operating is easy, and speed is fast, and the clamping tendon is firm, and easy damaged tendon and stndon sheath do not have hands surgical clinical application value.

The specific embodiment

Introduce embodiment of the present utility model below in conjunction with accompanying drawing:

This Tendon forceps is made up of binding clip, claw beam and pincers handle three parts.

Binding clip contains upper jaw (1), lower jaw (2) and the axis of guide (4), upper jaw (1) tail end and the axis of guide (4) front end and lower jaw (2) stage casing are flexibly connected by bearing pin (5) (6) respectively, and the axis of guide (4) rear end and lower jaw (2) tail end fairlead are slidingly matched.The upper and lower jaw of binding clip is the spindle shape when closed, and the surperficial radian of lower jaw (2) is smaller than upper jaw (1); Each is fluted in the upper and lower jaw, and both are provided with three the taper teeth (3) that are positioned at the Atria summit in the groove, and taper tooth (3) point is a little more than the groove plane, up and down crown respectively correspondence stagger a little.Binding clip during according to closure diameter several specifications such as 3.5mm, 4.5mm, 5.5mm, 6.5mm can be arranged, the patient who is suitable for stndon sheath to vary in size uses.
