Abstract

Provided is a uterine fibroid gripper, comprising two clamp heads (1) and clamp handles (4) fixedly connected to the two clamp heads (1); said two clamp handles (4) are articulated; said clamp heads (1) are arcuate surfaces; a ratchet-wheel mounting plate (8) is fixed on one clamping handle (4); said ratchet-wheel mounting plate (8) is provided with a ratchet wheel (7); the other clamping handle (4) is hinged to a pawl (5); said pawl (5) fits with the ratchet wheel (7); a tightening bolt (3) used for securing the ratchet wheel (7) is provided between the ratchet wheel (7) and the ratchet mounting plate (8). The beneficial effects of the uterine fibroid gripper are: (1) a simple structure; (2) it is easy to clamp a uterine fibroid without causing the uterine fibroid to rupture; (3) it is unnecessary to continuously hold the clamp handle, and use is easy; (4) the tightening bolt is an ingot bolt, which is easy to tighten or loosen; (5) slippage of the clamp handle is prevented.

Description

Uterine fibroid gripper

Technical field

The invention relates to a medical instrument for gynecological surgery, in particular to a uterine fibroid holder.

Background technique

Uterine fibroids are a common benign tumor of the uterus. The most important treatment is to perform resection. For larger uterine fibroids, when cutting, a special clamping device is needed to clamp the uterus. The fibroids are slippery or ruptured. At present, when the uterine fibroids are clamped, the surgical forceps are generally used for clamping. Since the existing surgical forceps have no self-locking ability, the doctor needs to continuously clamp the forceps of the surgical forceps. In addition, the front end of the existing surgical forceps has a planar structure, so when the uterine fibroids are clamped, the uterine fibroids are subjected to a large force and are thus easily broken.

Summary of the invention

The problem to be solved by the present invention is to provide a uterine fibroid gripper which is simple in structure, has self-locking ability and thus is convenient to hold and is not easy to cause rupture of uterine fibroids.

In order to solve the above technical problem, the uterine fibroid holder of the present invention comprises two clamping heads and a clamping handle fixedly connected to the two clamping heads respectively, the two clamping handles are hinged, the clip The holding head is a curved surface, a ratchet mounting plate is fixed on the one clamping handle, a ratchet wheel is arranged on the ratchet mounting plate, and a pawl is hinged on the other clamping handle, the spine The claw is matched with the ratchet, and a fixing bolt for fixing the ratchet is provided between the ratchet and the ratchet mounting plate.

In order to facilitate loosening or tightening of the tightening bolt, the uterine fibroid gripper of the present invention is the ingot bolt.

Further, in the uterine fibroid holder of the present invention, a buffer spring is disposed between the two gripping handles.

In order to facilitate grasping the gripping handle, the uterine fibroid holder of the present invention has a handle at the end of the gripping handle, and the handle is provided with a pattern for increasing friction.

The beneficial effects obtained by the invention are as follows: (1) the structure is simple; (2) the two clamping heads are all curved surfaces, which are convenient for clamping the uterine fibroids without causing rupture of the uterine fibroids; (3) a clip A ratchet mounting plate is fixed on the handle, a ratchet wheel is arranged on the ratchet mounting plate, and a pawl is hinged on the other clamping handle, the pawl is matched with the ratchet, and a fixed ratchet is arranged between the ratchet and the ratchet mounting plate. When tightening the bolts and thus clamping the uterine fibroids, as the two gripping handles are gradually closed, the pawls will continuously slide along the ratchet teeth of the ratchet, since the ratchets are fixed by the tightening bolts, thereby placing the two clips The position of the handle is locked, and the self-locking of the grip handle is realized, so that the doctor does not need to continuously clamp the grip handle during the use of the hysteromyoma gripper of the invention, and is convenient to use; (4) the tightening bolt is Ingot bolts are easy to tighten or loosen; (5) The ends of the grip handles are provided with a handle, and the handle is provided with a pattern for increasing friction, so that the doctor can grasp the grip handle to avoid slippage of the grip handle.

detailed description

As shown in FIG. 1 and FIG. 2, the uterine fibroid holder of the present invention comprises two clamping heads 1 and a clamping handle 4 fixedly connected to the two clamping heads 1, respectively, and the two clamping handles. 4 phases are hinged, the clamping heads 1 are all curved surfaces, and a ratchet mounting plate 8 is fixed on the one clamping handle 4, and the ratchet mounting plate 8 is provided with a ratchet 7 on the other A pawl 5 is hinged on the handle 4, and the pawl 5 is matched with the ratchet 7 , and a tightening bolt 3 for fixing the ratchet 7 is disposed between the ratchet 7 and the ratchet mounting plate 8; 3 is an ingot bolt; a buffer spring 2 is disposed between the two gripping handles 4; a handle 6 is disposed at an end of the gripping handle 4, and the handle 6 is provided with a pattern for increasing friction.

The uterine fibroids holder of the invention has a simple structure, and the two clamping heads 1 are all curved surfaces, which are convenient for clamping the uterine fibroids. Does not cause uterine fibroids to rupture.

In the uterine fibroid holder of the present invention, a ratchet mounting plate 8 is fixed on a clamping handle 4, a ratchet wheel 7 is arranged on the ratchet mounting plate 8, and a pawl 5 is hinged on the other clamping handle 4. The pawl 5 is matched with the ratchet 7 , and the set screw 3 for fixing the ratchet 7 is provided between the ratchet 7 and the ratchet mounting plate 8 , so that when the uterine fibroids are clamped, the two gripping handles 4 are gradually closed. The pawl 5 will continuously slide along the ratchet of the ratchet 7, and since the ratchet 7 is fixed by the tightening bolt 3, the position of the two gripping handles 4 is locked, and the self-locking of the gripping handle 4 is realized, so that the doctor is using In the process of the uterine fibroids holder of the present invention, it is not necessary to continuously clamp the gripping handle 4, and it is convenient to use.

In the uterine fibroid holder of the present invention, the tightening bolt 3 is an ingot bolt, which is convenient for tightening or loosening.

In the uterine fibroid holder of the present invention, the end of the gripping handle 4 is provided with a handle 6, and the handle 6 is provided with a pattern for increasing friction, so that the doctor can grasp the gripping handle 4 and prevent the gripping handle 4 from slipping off.
