Description

A kind of pelvic hemostatic forceps

technical field

The utility model relates to a pelvic cavity hemostat, which belongs to the field of medical instruments.

Background technique

At present, the problem of massive bleeding is often encountered during clinical operations. For bleeding and massive bleeding during pelvic organ surgery (especially obstetric hysterectomy), it is necessary to use effective and non-invasive hemostatic instruments. Considering the special characteristics of the pelvic cavity Due to the anatomical structure, the existing hemostatic devices cannot adapt to the curvature and depth of the side wall of the pelvic cavity, and cannot achieve the expected purpose of hemostasis. The tension of the existing non-invasive hemostatic devices is insufficient, and the clamping tissue, especially the changes in the anatomical structure during pregnancy, the tissue becomes wide and rich in blood supply, and the curvature does not meet the needs of pelvic surgery; in order to adapt to the pelvic surgery process The curvature of the pelvic side wall, effective and non-invasive hemostasis, new hemostatic devices are essential.

Utility model content

The technical problem solved by the utility model is that, when bleeding or massive bleeding occurs during pelvic visceral surgery (especially obstetric hysterectomy), the surgical field of view is not clear and covered by blood, so the exact position of the bleeding point cannot be effectively determined.

The technical solution of the utility model is to provide a pelvic hemostatic forceps, including two forceps bodies symmetrical to each other, each forceps body includes a handle and a clamping end, and the length ratio of the handle and the clamping end is 1.5:1～ 2.5:1, the clamping end includes the first clamping end, the second clamping end and the third clamping end which are connected successively and are located in the same plane; the angle between the first clamping end and the second clamping end is 130-160 degrees, the angle between the second clamping end and the third clamping end is 120-150 degrees.

Further, the second clamping end is provided with clamping teeth.

Further, the length of the first clamping end is 4-8cm.

Further, the length of the second clamping end is 3-6 cm.

Further, the length of the third clamping end is 1-2 cm.

Further, the handle includes a pliers handle with one end connected to the first clamping end, and the other end of the pliers handle is provided with a card slot and a handle ring.

The utility model is aimed at the requirements of the tension and physiological curvature of the pelvic tissue, adopts thinner and slightly shallow alveolar to achieve the purpose of no trauma, and adjusts the clamping end and the handle end through the improvement of the clamping force and curvature. Length ratio (1:1.5 ~ 1:2.5) to adjust the tension, so that the tension is greater than the current vascular blocking forceps, considering the particularity of the pelvic cavity structure, in order to adapt to the radian and depth of the pelvic cavity, the utility model designs the pelvic cavity hemostatic forceps No. The included angle between the first clamping end and the second clamping end is 130-160 degrees, and the included angle between the second clamping end and the third clamping end is 120-150 degrees. The length of the first clamping end is 4-8cm, the length of the second clamping end is 3-6cm, the length of the third clamping end is 1-2cm, and the second clamping end is equipped with clamping teeth, which is especially suitable for basins. Hemostasis on wall, parauterine and other parts.

The pelvic hemostat of the utility model can also effectively clamp the broken end of the vagina, conveniently and quickly expose the gap behind the bladder, and form a certain safe area and tension, thereby safely and effectively separating the bladder, while reducing the risk of bladder injury and bleeding, and is easy to operate ,Simple.

The beneficial effect of the utility model is that, especially for the clamping of the broken end of the vagina, corresponding adjustments can be made on the existing design, because the anatomical structure changes during pregnancy, and the vaginal end becomes wider, and most of the currently used instruments are used for blood vessels and a small amount of tissue For clamping, the clamping end cannot reach enough length to completely clamp the vaginal stump from both sides. On the basis of the existing design, by lengthening the clamping end, the vaginal end can be clamped effectively from both sides without gradually separating the clamps, which is convenient and quick to expose the space behind the bladder, simplifying the operation, and the unique upturned design of the clamping end tail , On the one hand, it can reduce the risk of tissue damage, and on the other hand, it is convenient for the operator to operate during the operation, such as ligation, wiring, etc.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Example 1

This embodiment provides a structural schematic diagram of a pelvic hemostat, as shown in FIG. The length ratio of the end is 2:1, and the clamping end includes the first clamping end 1, the second clamping end 2 and the third clamping end 3 which are connected in sequence and located in the same plane, and the lengths are 5cm and 4cm respectively. , 1cm; the angle between the first clamping end 1 and the second clamping end 2 is 135 degrees, the angle between the second clamping end 2 and the third clamping end 3 is 140 degrees, the connection between the clamping ends There are rounded transitions at the end and the end of the third clamping end 3 to reduce damage to the tissue. The second clamping end 2 is provided with mutually engaging clamping teeth 4, and the handle includes one end connected to the first clamping end 1. The clamp handle 6, the other end of the clamp handle 6 is provided with a slot 5 and a handle ring 7, and the slots 5 on the two clamp bodies are engaged with each other to adjust the clamping force of the clamping end, so as to meet the needs of hemostasis in different occasions. If a bleeding point is seen during the operation, the slot 5 of the pelvic hemostat can be loosened directly so that the clamping end clamps the bleeding site, and the slot 5 is closed to achieve the hemostatic effect.
