Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a hemostatic forceps for emergency parturients. Background Art
[0002] When performing surgeries on women, obstetricians and gynecologists most often use hemostatic forceps. Hemostatic forceps are a common medical device used in general surgery. Vascular forceps can separate and clamp tissue and blood vessels. Hemostatic forceps primarily consist of a base, a jaw, and a handle. The two handles intersect symmetrically and are connected by an axis at the intersection to form the entire hemostatic forceps. During use, the hemostatic forceps clamp the ruptured or damaged blood vessel, thereby achieving the purpose of hemostasis.
[0003] At present, most of the existing hemostatic forceps used for maternal emergency treatment have relatively single functions. During use, it is difficult to continuously control the clamping force, resulting in a certain degree of bleeding due to too little clamping force, and a certain degree of bleeding due to too much clamping force. The applicability is low because the blood vessels may rupture, thereby causing certain harm to the mother. Therefore, we propose a hemostatic forceps for maternal emergency treatment. Utility Model Content
[0004] The purpose of the utility model is to provide a hemostatic forceps for emergency use in parturients, so as to solve the existing problems raised in the above background technology.
[0005] The lever arm is pivotally connected to the second end of the second lever by a pin, and the lever arm is pivotally connected to the first end of the second lever by a pin.
[0006] Preferably, a clamping spring is provided at the bottom of the clamping block, and two ends of the clamping spring are fixedly connected to the inner bottom surface of the second L-shaped plate and the bottom of the clamping block respectively.
[0007] Preferably, one end of the pressing block extending into the interior of the second L-shaped plate is provided with a lifting spring, and both ends of the lifting spring are fixedly connected to the top wall of the second L-shaped plate and the top of the pressing block respectively.
[0008] Preferably, limiting grooves are provided on both sides of one inner end of the second L-shaped plate, and limiting blocks are provided on both sides of the bottom end of the clamping block. The limiting blocks extend into the interior of the limiting groove and are slidably connected to the inner wall thereof.
[0009] Preferably, a movable groove is provided in the middle of the rotating rod, and the rotating rod is movably connected to the second rotating shaft through the movable groove provided in the middle, and the length of the movable groove is greater than the diameter of the second rotating shaft.
[0010] Preferably, the first clamp rod and the second clamp rod are both provided with clamp mouths on opposite sides of one end away from the first L-shaped plate and the second L-shaped plate, and the clamp mouths are fixedly connected to the first clamp rod and the second clamp rod respectively.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. By utilizing the positioning groove at the bottom of the first L-shaped plate, cooperating with the clamping block at the top end of the second L-shaped plate and the clamping spring, the first L-shaped plate and the second L-shaped plate are clamped and positioned, thereby achieving the purpose of positioning the first clamp rod and the second clamp rod, thereby ensuring the stability of the clamping force of the clamp mouth, so that during the second process, the surgeon does not need to continuously apply force to the clamp body, which greatly ensures the stability of the clamping force.
[0013] 2. By utilizing the pressure block, rotating rod and pressure rod, the function of driving the clamping block to retract is realized. When it is necessary to release the clamping state or adjust the continuous clamping force, it is only necessary to press the pressure block to drive the clamping block to retract, thereby achieving the purpose of releasing the clamping state, so as to facilitate adjusting the clamping force or removing the pliers body, greatly improving the convenience of use.
