Description
Technical Field
The invention relates to a pair of hemostatic forceps, in particular to a pair of hemostatic forceps for clamping uterine artery.
Background
After vaginal delivery and cesarean section, postpartum hemorrhage tends to clamp uterine artery descending branches at two sides of cervix, uterine blood supply is reduced, and the aim of reducing postpartum hemorrhage is achieved. The hemostatic forceps that use at present clinically are longer, and at the forceps holder in-process, the forceps holder part opens and shuts many times, causes the extrusion repeatedly to patient's health tissue, aggravates patient's painful degree, and probably causes the mistake to press from both sides normal health tissue, increases doctor's the operation degree of difficulty.
Disclosure of Invention
The invention aims to solve the existing problems and provides a pair of hemostatic forceps for clamping uterine artery, which has reliable structure, reduces the pain of a patient due to the fact that a forceps rod part does not need to be opened or closed, and reduces the operation difficulty of a doctor.
In order to solve the technical problem, the technical scheme of the invention is realized by the following modes: the utility model provides a hemostatic forceps for pincers uterus artery, includes tong pole, symmetrical pincers handle, pincers, and the tong pole front end is connected through the round pin axle construction with the pincers, and the tong pole rear end is connected through the round pin axle construction with the pincers handle.
The clamp rod is cylindrical, a square sliding groove is formed in the center of the clamp rod, a square sliding rod is arranged in the sliding groove, the sliding rod and the sliding groove are in sliding connection, and symmetrical racks are arranged on two sides of the front end of the sliding rod respectively.
The forceps holder is provided with a gear along the circumferential direction of the center of the pin shaft, and the gear and the rack form meshing transmission.
The rear ends of the sliding rods are connected with the 2 forceps handles through connecting rods respectively, and the connecting rods are connected with the sliding rods and the forceps handles through pin shaft structures.
Therefore, the forceps holder can be driven by the slide rod to synchronously open and close by operating the opening and closing of the forceps handle, so that the opening and closing action of the forceps rod part is omitted, the pain of a patient is reduced, and the operation difficulty of a doctor is reduced.
The technical scheme of the invention is further defined as follows:
the foregoing hemostat for clamping uterine artery: the pincers include the pincers leaf of sheet metal form, and the pincers leaf passes through muscle and gear connection, and the pincers leaf is the arc and is equipped with the bar breach in its middle, and the pincers leaf is bigger than the pincers leaf in traditional hemostatic forceps, more is favorable to stanching, and the bar breach can prevent the position overlength of pincers simultaneously, causes local blood loss necrosis.
The foregoing hemostat for clamping uterine artery: 2 pincers handle sides are equipped with arc rack chute and locking claw assembly respectively, locking claw assembly includes and forms locking complex locking claw with arc rack chute, the locking claw passes through lamellar flexure strip to be fixed in the pincers handle side, one side of keeping away from arc rack chute at the flexure strip and the position that is close to the locking claw is equipped with the driving lever, like this when closed 2 pincers handles, locking claw and arc rack chute locking, thereby make 2 pincers clenches, reach hemostatic effect, when stirring the driving lever, locking claw and arc rack chute separate, can loosen 2 pincers handles, thereby loosen the pincers clamp.
The foregoing hemostat for clamping uterine artery: the forceps rod, the forceps handle, the forceps clamp, the connecting rod, the sliding rod, the arc-shaped bevel rack and the locking claw assembly are made of medical-grade metal with good toughness, so that the locking claw assembly has good elasticity, the stable and reliable locking function of the locking claw assembly is guaranteed, and all parts in contact with the body of a patient can be guaranteed to have the advantages of corrosion resistance, rust resistance, no toxicity and no harm.
The foregoing hemostat for clamping uterine artery: the clamp rod and the clamp protruding structure part are designed to be rounded corners, so that the device can be effectively prevented from injuring the body of a patient due to too sharp edges and corners.
The invention has the beneficial effects that: the forceps can be driven by the slide rod to synchronously open and close by opening and closing the forceps handle, so that the opening and closing action of the forceps rod part is omitted, the pain of a patient is reduced, and the operation difficulty of a doctor is reduced. The forceps leaf is bigger than that of the traditional hemostatic forceps, so that hemostasis is facilitated, and meanwhile, the strip-shaped notch can prevent the forceps clamp from being too long to cause local blood loss and necrosis. When 2 closed pincers handles, locking claw and arc rack diagonal locking to make 2 pincers clamps close, reach hemostatic effect, stir the driving lever, locking claw and the separation of arc rack diagonal can loosen 2 pincers handles, thereby loosen the pincers clamp. The forceps rod, the forceps handle, the forceps clamp, the connecting rod, the sliding rod, the arc-shaped bevel rack and the locking claw assembly are made of medical-grade metal with good toughness, so that the locking claw assembly has good elasticity, the stable and reliable locking function of the locking claw assembly is guaranteed, and all parts in contact with the body of a patient can be guaranteed to have the advantages of corrosion resistance, rust resistance, no toxicity and no harm. The clamp rod and the clamp protruding structure part are designed to be rounded corners, so that the device can be effectively prevented from injuring the body of a patient due to too sharp edges and corners.
