Abstract

The utility model relates to a self-locking tourniquet belonging to an appliance for bonding object for operation intention. The problems to be solved are that the new technical proposal replaces the existing operation that people use tongs to clamp a rubber tube to carry out the haemostasis operation before hysteromyoma and salpinx uterine horn implantation operations, which brings the phenomenon of affecting the visual field, hindering operation and damaging urinary bladder and salpinx. The utility model is characterized in that one end of a rubber tube is tied with a sliding seal lock which is composed of a lock body, a draw ring, and a connecting rod; when the self-locking tourniquet is used, the rubber tube passes the object which needs hemostasis to be tensed after the rubber tube passes through a lock body hole and the draw ring to rotate so as to drive the draw ring with the connecting rod to a dead angle. The utility model realizes self-locking hemostasia and is suitable for the hysteromyoma and the salpinx uterine horn implantation operations.

Description

Self-locking tourniquet

The tourniquet of energy self-locking belongs to the apparatus of paying object for operation purpose bundle.

When making hysteromyoma, fallopian tube cornua uteri at present and planting operation, tighten up for after reducing that the uterus wound surface is hemorrhage and generally all walking around ovary funnel ligament with rubber tube, the reuse hands is held small vessel forceps and is clamped sebific duct blocking-up uterus and ovarian artery.Thisly hold rubber tube hemostatic shortcoming with hands, pincers supports and be: taking vascular forceps to clamp in the operating process of rubber tube with hands, in case hands, pincers move with it during the push-and-pull uterus, damage bladder sometimes, even fallopian tube pelvic cavity section, in addition, hands, pincers hinder the exposure and the operation technique of surgical field of view.

The purpose of this utility model: a kind of new technical scheme is provided, addresses the deficiencies of the prior art, realize clamping hemostasis without hand vice, the operation of the art of might as well the being in the way visual field and operation can avoid damaging the phenomenon of bladder or fallopian tube pelvic cavity section again.

The realization the technical solution of the utility model is: fasten a self-tightening lock 1 with an end of rubber tube 4, the self-tightening lock is made of lock body 1, draw ring 2, connecting rod 3, have can being connected on the lock body 1 by chain 5 by rotating connecting rod 3 of draw ring 2, the other end of lock body 1 has a hole by rubber tube 4, and a side in hole has one to cooperate localized groove with draw ring.

Below in conjunction with Figure of description this utility model is further specified:

Fig. 1: be concrete structure figure of the present utility model.

Fig. 2: be user mode figure of the present utility model.

In Fig. 1, the 1st, lock body, the 2nd, draw ring, the 3rd, connecting rod, the 4th, rubber tube, the 5th, hinge.

With reference to Fig. 1, the bottom surface of lock body 1 is lonely shape, and end face is a shaped form, and the both sides profile of connecting rod 3 also is lonely shape accordingly, the two ends end face of connecting rod 3 open shelves, an end is for being used for installing revolution, an end is in order to avoid rubber tube 4, not so lock body 1 must strengthen.Between through hole and groove that draw ring 2 matches, a boss be arranged, rubber tube 4 has the pulling force of effect after when tightening, and the purpose of boss is to increase frictional force, decomposes again to reduce this back working tension.Self-tightening lock is made best of stainless steel material, with other metal material electroplate also can, be that a root rubber pipe or two are all right on the lock body 1, the rope of usefulness plastics, Buddhist nun's down material is good.

Note when using this utility model, after rubber tube 4 is walked around ovary funnel ligament, tighten up rubber tube 4 after earlier rubber tube 4 being passed lock body 1 hole and draw ring 2, again draw ring 2 is placed on the bar 3 that is rotationally connected on the groove orientation that is mated, make it forward the dead point to, the draw ring 2 that driven this moment just is tightened to rubber tube 4 in the groove, has reached the purpose of self-tightening.After having performed the operation, start connecting rod 3, rubber tube 4 loosens.

The utility model is the advantage of prior art relatively: add the pincers operation without hand, so do not affect the visual field, a staff has also been saved in the operation of the art of might as well being in the way, and can not damage bladder and fallopian tubal pelvic cavity section because of hand vice. The utility model is easy and simple to handle, laborsaving. Overcome the defective of prior art, realized that hemostasis does not affect the visual field, the art of might as well being in the way operation without the operation of hand vice before the operation, avoided damaging because of hand vice the goal of the invention of bladder or fallopian tubal basin section. The utility model is that gynaecology is used as the desirable apparatus that fibroid, fallopian tubal cornua uteri are planted surgical hemostasis.

Claims

The tourniquet of energy self-locking, it is characterized in that: rubber tube 4 ends be self-tightening lock 1, self-tightening lock 1 is made of lock body 1, draw ring 2, connecting rod 3, have can being connected on the lock body 1 by hinge 5 by rotating connecting rod 3 of draw ring 2, the other end of lock body 1 has a hole by rubber tube 4, and a side in hole has one to cooperate localized groove with draw ring 2.
