Abstract

It the utility model is related to a kind of medical clamp, including clamp handle, claw beam, binding clip, it is characterised in that the binding clip is hollow ring, and claw beam and binding clip are wide-angle transition radian.It is easy to corresponding vessel position on the accurate clamp uterine neck of clinician, even if maloperation occurs, binding clip can also be taken out, avoid long-time clamp tissue from causing to lose, is finally reached accurate, satisfied and hurtless measure uterine neck blood vessel blocking effect.

Description

a medical clamp

technical field

The utility model relates to a clamp device for blocking blood supply in medical treatment, in particular to a cervical clamp for blocking the main blood supply of the cervix.

Background technique

At present, when placenta previa or low-lying placenta lead to poor contraction of the lower uterine segment and postpartum hemorrhage, the hospital uses traditional cervical forceps (sponge forceps) to clamp the descending branches of the uterine artery at the 3 o'clock and 9 o'clock of the cervix. When using this function, the disadvantages of traditional cervical forceps include: 1) They are all straight or small-angled (generally no more than 45 degrees), and the direction of the forceps head is almost parallel to the course of cervical blood vessels, which makes it difficult to completely block the blood vessels when clamping Blood supply, hemostatic effect is not satisfactory. 2) The forceps head is closed and hollow, so it is easy to suture and fix the cervical tissue and the forceps head during suturing. Once this happens, the sutures need to be removed and a second operation performed. 3) Most of the forceps heads are toothed, and the cervical tissue is clamped for a long time, which is easy to cause tissue damage and necrosis, resulting in bleeding and postoperative infection.

Utility model content

The utility model mainly solves the above problems and provides a cervical blood vessel blocking clamp that is convenient for doctors to use, helps accurately block the blood supply of the cervix, improves the effect of hemostasis treatment, reduces the cost of equipment, and reduces the misoperation of medical personnel. The technical scheme is as follows :

A medical clamp includes a pliers handle, a pliers rod, and a pliers head, and is characterized in that the pliers rod and the pliers head have a large-angle transition arc.

Further, the radian is 60-80 degrees.

Further, the pliers head is hollow and ring-shaped.

Further, the ring is circular or elliptical.

Further, it is characterized in that the ring has an opening.

Further, it is characterized in that the opening is located away from the pincer rod.

Further, it is characterized in that the length of the opening is 0.3-0.5 cm.

Further, it is characterized in that the area of the ring is

Further, it is characterized in that the clamp is cervical forceps.

Further, the inner side of the pliers adopts a smooth surface structure without tooth lines.

The beneficial effects produced by the utility model are as follows: the design of the large-curved elbow can meet the needs of clinicians to accurately clamp the corresponding blood vessels on the cervix; the non-closed hollow oval forceps head can take out the forceps head even if misoperation occurs during suturing; The design of no teeth on the inside of the head avoids the loss of tissue caused by long-term clamping; different specifications and lengths of the forceps rod make this forceps suitable for patients with various conditions, and finally achieve accurate, satisfactory and non-invasive cervical vascular occlusion effect.

Detailed ways

Below in conjunction with accompanying drawing and example the utility model is described further:

As shown in FIG. 1 , the cervical blood vessel blocking forceps includes: 1. a forceps handle, 2. a rotating shaft, 3. a forceps rod, 4. a forceps head, and 5. a locking structure. The pliers handle 1, pliers rod 3 and pliers head 4 are integrally formed by casting, and the instrument includes two pliers rods 3, which are hinged together by rotating the drawer 2, and the pliers rods 3 are relatively rotatable.

The transition between the pliers rod 3 and the pliers head 4 adopts a large-angle arc design, preferably with an arc of 60 degrees to 80 degrees.

The pliers head 4 is a non-closed hollow ring, which can be circular or elliptical in shape. The opening is set at the attachment end of the pliers head away from the pliers rod, and the length is about 0.3 cm to 0.5 cm. The area of the annular structure of the forceps head is between 1-1.5 square centimeters, and the surface of the annular structure in contact with the cervix is a smooth surface structure without tooth lines. The cross-sectional area of the ring structure is between 1-1.5 square centimeters

The length of the pincer rod 4 is adjustable, suitable for vaginal operations of different depths, and can be a scalable stepless adjustment structure or a scalable step-by-step adjustment structure.

The locking structure adopts a multi-tooth meshing structure.

The utility model can facilitate clinicians to accurately clamp the corresponding blood vessels on the cervix. Even if misoperation occurs, the forceps head can be taken out to avoid loss of tissue caused by long-term clamping, and finally achieve accurate, satisfactory and non-invasive cervical vascular occlusion Effect.
