Abstract

The invention relates to a cervical vessel occlusion clamp which comprises a clamp handle, a rotating shaft, clamp rods and a clamp head, wherein the clamp handle, the clamp rods and the clamp head are integrally formed by casting; and the two clamp rods are hinged together through the rotating shaft. Transition of the clamp rods and the clamp head adopts a 60-80-degree arc design; the clamp head is of a non-closed hollow ellipse, and the inner side is of an insection-free smooth surface structure, so that a clinical doctor can accurately clamp corresponding blood vessels on the cervix. Even if misoperation occurs, the clamp head can be taken out, the condition that loss is caused due to long-term tissue clamping is avoided, and finally, the accurate, satisfied and noninvasive cervical vessel occlusion effect can be achieved.

Description

A kind of medical clamp

Technical field

The present invention relates to one kind medically blocks blood supply fixture apparatus, more particularly to a kind of cervical clampss, for blocking son Cervix uteri major blood is supplied.

Background technology

At present, when placenta previa or low implantation of placenta state cause lower uterine segment to shrink not good and postpartum hemorrhage, hospital application Descending position of uterine artery of traditional 3 points and 9 points of cervical clampss (sponge forceps) clamp cervix uteri.During using this function, traditional cervix uteri Pincers shortcoming includes：1) straight peen or low-angle elbow (being usually no more than 45 degree), its binding clip direction and cervix uteri blood vessel traveling are It is almost parallel, cause to be difficult to thoroughly block blood vessel blood supply during clamp, haemostatic effect is unsatisfied with.2) binding clip is hollow for closure, suture Shi Rongyi fixes cervical tissue and binding clip suture.Once this kind of situation of generation, needs to remove stitching thread and carry out secondary operation. 3) to there is groove, long-time folder closes cervical tissue, is easily caused tissue injury and necrosis most of binding clip, causes bleeding and postoperative Infection.

The content of the invention

It is of the invention main by solving the above problems, there is provided a kind of to facilitate doctor to use, help accurately blocking cervix uteri blood For, hemostatic treatment effect is improved, equipment cost is reduced, reduce the cervix uteri vascular occlusion clamp of medical worker's maloperation, its technical side Case is as follows：

A kind of medical clamp, including clamp handle, claw beam, binding clip, it is characterised in that claw beam is wide-angle transition arcs with binding clip Degree.

Further, the radian is 60-80 degree.

Further, the binding clip is hollow ring.

Further, the annular is circular or oval.

Further, it is characterised in that the annular has opening.

Further, it is characterised in that the opening is located remotely from claw beam position.

Further, it is characterised in that the Opening length is 0.3-0.5 centimetre.

Further, it is characterised in that it is described annular area be

Further, its feature is cervical clampss in the fixture.

Further, the binding clip inner side adopts the shiny surface structure without groove.

The beneficial effect that the present invention is produced has：The accurate clamp cervix uteri of clinician disclosure satisfy that by big radian bend design Upper corresponding vessel position；Even if non-closed hollow ellipse clamp head makes that maloperation occurs during suture, it is also possible to take out binding clip；Binding clip Inner side avoids long-time clamp tissue from causing loss without groove design；Different size length claw beam causes this pincers to be applied to various feelings Condition patient, is finally reached accurate, satisfied and AT cervix uteri blood vessel blocking effect.

Specific embodiment

Below in conjunction with the accompanying drawings the present invention will be further described with example：

As shown in figure 1, cervix uteri vascular occlusion clamp includes：1st, clamp handle, 2, rotary shaft, 3, claw beam, 4, binding clip, 5, locking knot Structure.The clamp handle 1, claw beam 3 and binding clip 4 include two claw beams 3 by casting global formation, the apparatus, and two claw beams 3 are by turning Dynamic to take out 2 hinges and be connected together, claw beam 3 is relative to can rotate.

The claw beam 3 is designed with the transition of binding clip 4 using wide-angle camber line, and preferred radian is 60 degree to 80 degree.

The binding clip 4 is non-closed hollow circular, and annular shape can be circular or oval, and it is remote that opening is arranged on binding clip From claw beam attachment end, 0.3 centimetre to 0.5 centimetre is about.The circulus area of binding clip between 1-1.5 square centimeters, ring-type The surface that structure is contacted with cervix uteri is the shiny surface structure without groove.The cross-sectional area of circulus 1-1.5 square centimeters it Between

The adjustable length of claw beam 4, the vagina operation of suitable different depth, can be that scalable electrodeless adjustment structure can also be Scalable stepping adjustment structure.

Buckle structure adopts many tooth engaging conformations.

The present invention produce can in order to corresponding vessel position on the accurate clamp cervix uteri of clinician, even if generation maloperation, Binding clip can also be taken out, it is to avoid long-time clamp tissue causes loss, is finally reached accurate, satisfied and AT cervix uteri blood vessel Barrier effect.
