Description

Double-tissue clip applier

Technical Field

The utility model relates to a medical appliance, in particular to a double-tissue clip applier or clip applier.

Background

In the pleuroperitoneal cavity clinical operation process, a tissue clip applier is generally used for clipping a tissue clip for clipping an incision tissue, and the tissue clip also comprises hemostasis and the like, the tissue clip is made of high polymer materials through injection molding and is V-shaped when opened, locking ports are formed in the front ends of two arms of the V-shaped tissue clip, and the tissue clip cannot be separated for reuse after being locked. The tissue clip locking arms, i.e., the clip stop arms, also have friction protrusions. The upper and lower jaws of the jaw of the existing tissue clamp applicator (such as HEMOLOK) open and close around the jaw shaft, and V-shaped tissues are clamped in the accommodating spaces of the upper and lower jaws when the jaws are opened; the upper and lower jaws of the clip applier are respectively provided with a pair of 1-1-1 front teeth and a pair of 1-1-2 rear teeth inside, the outer sides of the front ends of two arms of a V-shaped tissue clip are provided with protrusions which are matched and matched, the protrusions on the two arms of the V-shaped tissue clip are stress points of the clip applier, a handle of the clip applier is pinched, the upper jaw and the lower jaw clamp tightly clamp and apply force to the front ends of the two arms of the V-shaped tissue clip to lock a locking opening, the V-shaped tissue clip becomes a straight shape, and can not be separated again, namely, a tissue clip is clamped.

However, in the use process of the existing tissue clip applier, the clip applier can only clamp one tissue clip at a time and close one tissue clip; when a thicker artery or an important blood vessel close to the heart end is clamped (including clamping a thicker tissue or bearing a certain pressure), two or more tissue clamps need to be applied, and an existing tissue clamp applicator is used for picking up one tissue clamp in a tissue clamp box (the tissue clamps in the tissue clamp box are sorted according to a standard posture, the V point is upward so that the applicator can pick up the tissue clamps, and the distance between the tissue clamps is about one millimeter); applying force to the operation part to lock the second tissue clamp; this can affect the efficiency of applying the tissue clip, with the longer the procedure takes, the higher the patient's risk of anesthesia or infection. Accordingly, it is desirable to provide a dual tissue clip applier or clip applier. Moreover, a double-fish-card tissue clip CN 105212986 a, involved by the present inventor, is a mature structure with locking structure, and is not much described in the present application; double fish card tissue clips also require double tissue clip appliers or clip appliers.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior tissue clip applier, the utility model provides a clip applier or a clip which can simultaneously apply one or two tissue clips. The utility model also aims to provide a clip applier or clip applier that can clip duplex or double tissue clips.

The utility model provides a technical scheme that its technical problem adopted is: a double-tissue clamp applicator comprises a clamp head, a clamp head shaft, a clamp rod, a handle shaft and a handle; the binding clip comprises an upper binding clip mouth and a lower binding clip mouth; the front end of the clamp rod is connected with the clamp head through the clamp head shaft, and the tail ends of the upper clamp mouth and the lower clamp mouth of the clamp head can be opened and closed around the clamp head shaft, namely the upper clamp mouth and the lower clamp mouth of the clamp head are opened and closed around the clamp head shaft; the clamp is characterized in that the clamp head is of a parallel double-clamp head structure, and the tail ends of an upper clamp mouth and a lower clamp mouth of the double clamp head are connected with the front end of a clamp rod and are opened and closed around a clamp head shaft; the distance between the two forceps heads is 0.5-2.5 mm; i.e. the distance between two parallel tissue clips in the tissue clip packaging box is the same.

The tail ends of the upper tong mouth and the lower tong mouth are in a curved shape; the angle between the clamp head and the clamp rod is 140-175 degrees.

The utility model discloses an embodiment in two pincers heads: a pair of front teeth 1-1-1 and a pair of rear teeth 1-1-2 are respectively arranged in the upper and lower jaws of the binding clip, so that the outer sides of the front ends of the two arms of the V-shaped tissue clip are matched and matched with each other in a protruding manner;

according to another embodiment of the double-clip of the utility model, the center of the upper and lower clip mouths of the clip is provided with a 1-1-1 front jaw tooth and a 1-1-2 rear jaw tooth, which make the central connecting end of the double-V-shaped tissue clip be provided with a convex matching fit;

side protrusions 1-1-3 are arranged inside the upper and lower plier mouths, and strip-shaped grooves are formed in the middles of the side protrusions; for defining and accommodating the V-shaped tissue clips.

The beneficial effects of the utility model, a binding clip has the ability of applying one or two tissue clamps simultaneously in this application scheme, can apply one or two tissue clamps promptly simultaneously. The second type of forceps head can clamp a duplex V-shaped tissue clamp (the forceps head and the forceps teeth can be slightly changed). The device is completely compatible with the existing tissue clip applier or clip applier in use, and the distance between the two forceps heads is 0.5-2.5 mm; namely, the distance between the tissue clips and the two parallel tissue clips in the tissue clip packaging box is the same, so that the clips can be taken out at the same time. The double-clamp simultaneous application can effectively prevent the problems that one clamp force is not enough and the clamp is easy to fall in the operation process, ensure the operation safety, reduce the operation intensity of the doctor and improve the operation efficiency.
