Description

The microtrauma type uterus raising device

Technical field

This utility model relates to medical apparatus and instruments, particularly the microtrauma type uterus raising device.

Background technology

In gynecological laparoscopic operation, generally need uterus raising device swing uterus, to expose the art open country, at present used uterus raising device is various in style, a kind of simple and easy uterus raising device is arranged, and its structure is to improve to form on the basis of original obstetrics and gynecology operation apparatus mouse tooth forceps, is made up of two leaves and hinge region, lobus dexter wherein is identical with former mouse tooth forceps profile and its head widened, and lobus sinister mouse tooth forceps partial design become a lengthening, the crooked rustless steel probe that certain radian is arranged to the inside.This probe cross section is shaped as circle or ellipse, and end of probe is hemispherical body or the slick surperficial body that radian is arranged.This is simple in structure, and is cheap, easy to use.

The uterus raising device that external import is also arranged, its structure and domestic uterus raising device are similar.

There is weak point to a certain extent in said structure: palace device clamp head part bare terminal end is all more sharp-pointed, and occlusal contact area is little, and cervix uteri damage is big, easily come off, the rotation uterus, when the clamping position of uterine neck is too high in addition the damage bladder arranged may.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provides that a kind of to overcome in the prior art cervix uteri clamping zone area little, and the cervix uteri damage is big, comes off the defective in rotation uterus, the microtrauma type uterus raising device that occlusal surface is big, damage is little.

For reaching above purpose, following technical proposal that this utility model adopts is:

The microtrauma type uterus raising device, comprise by binding clip, vice body and egg type and refer to enclose the lobus sinister that constitutes and refer to enclose the lobus dexter that constitutes by probe, vice body and egg type, the vice body of described two leaves is connected by connecting device, two egg types refer to that correspondence is provided with the lock teeth between the circle, the described probe radian that curves inwardly is 0.523～0.785, described tips of probes is hemispherical body, described binding clip is an arc fine strip shape tooth, the occlusal surface zone that described binding clip is corresponding with the offside retaining part is square fine strip shape, and the occlusal surface of described probe and binding clip raises up.

The occlusal surface engagement of described binding clip and probe.

Described connecting device is a hinge.

Described microtrauma type uterus raising device material is a rustless steel.

This utility model can reach following beneficial effect after adopting technique scheme:

1, invasive.The binding clip of this utility model arc fine strip shape tooth more meets the anatomical structure of cervix uteri, has invasive, not eely distinguishing feature, and probe is crooked to the inside, and the top is slick spheroid, stretches into cavity of uterus in the art and holds up the uterus, plays the effect of support.

2, use is stable.This utility model in the peritoneoscope operation on uterus on, extract operation is very easy, because occlusal contact area increases, more is difficult for slippage.

3, safety.This utility model lobus sinister probe is an arc, and the radian that curves inwardly is 0.523～0.785, meets the physiology camber of uterine cavity, and is little to internal film tissue's damage, also exposes the different parts in uterus in the art easily; Occlusal surface increases, and inboardly changes the wave fine strip shape into by dentation, and is minimum to the loss of cervix uteri, also can not go up very much and may damage bladder because of the interlock position.

4, more become reasonable than prior art.This utility model is through facts have proved, its more reasonable structure, and the more stable maturation of technology, various performance parameters all is improved, and has more advance than prior art.

5, long service life.This utility model sound construction, stable performance, long service life have the vast market economic benefit.

The specific embodiment

Below in conjunction with drawings and the specific embodiments this utility model is described in further detail:

Referring to Fig. 1

Fig. 1 is a structural representation of the present utility model, in Fig. 1, this utility model comprises by binding clip 2, vice body 4 and egg type refer to enclose 6 lobus sinisters that constitute and reach by probe 1, vice body 4 and egg type refer to enclose 6 lobus dexter that constitute, the vice body 4 of described two leaves is connected by connecting device 3, correspondence was provided with lock teeth 5 between two egg types referred to enclose 6, described probe 1 is the rustless steel probe 1 that a bending to the inside has certain radian (0.523～0.785), described probe 1 top is hemispherical body, described binding clip 2 is an arc fine strip shape tooth, and the occlusal surface zone 21 that described binding clip 2 is corresponding with the offside retaining part is square fine strip shape.Like this, in operating process, owing to increased occlusal surface, and so the damage to cervix uteri is little in art, working stability, postoperative effect is good, has reduced patient's misery.

Described connecting device 3 can adopt hinge or other structures.

Existing uterus raising device clamp head part bare terminal end is all more sharp-pointed, and the area of joining is little, damages cervix uteri in the art easily, comes off the rotation uterus.

This utility model is gone up, extract operation is very easy, can not damage because of pincers portion sharply causes cervix uteri, also can not rotate the uterus, can be widely used in the gynecological laparoscopy operation on uterus in gynecilogical operation.

Referring to Fig. 2

Fig. 2-A is a lobus sinister vertical view of the present utility model; Fig. 2-B is this utility model lobus sinister binding clip upward view; At Fig. 2-A, among the B, described binding clip 2 is an arc fine strip shape tooth, the occlusal surface zone 21 (as shown in Figure 3) corresponding with the offside retaining part is complementary, like this, when this utility model is applied to suitable environment, owing to increased binding clip 2 and probe 1 area of engagement region 21 mutually, and the stria that is provided with on the stria of the binding clip 2 bottom surfaces occlusal surface zone 21 corresponding with probe 1 retaining part is meshed, increased the steadiness of clamping, it is little to improve the area of joining that sharply causes because of the binding clip bare terminal end in the prior art effectively, the unsteady defective of clamping, increased occlusal surface, make its structure more meet structoure of the human body, its end face structure more becomes reasonable than prior art structure.

Referring to Fig. 3

Fig. 3-A is this utility model lobus dexter partial side view; Fig. 3-B is this utility model lobus dexter partial top view.In Fig. 3-A, B, arc probe 1 is corresponding with 2 interlocks of lobus dexter binding clip regional 21, and described engagement region 21 raises up, the fine strip shape dentation is square, its area and binding clip 2 bottom surfaces are complementary, and binding clip 2 is enclose engagement region 21 well, and the art tool is melted mutually with structoure of the human body better.

Its operating process: behind the perineum vaginal disinfection, specula exposes cervix uteri, insert egg type with finger and refer to enclose in 6, uterus raising device is inserted uterus raising device probe portion 1 from specula outside transvaginal along the uterine cavity direction, until 2 about 2cm place's interlocks on cervix uteri mouth outer rim of uterus raising device binding clip, fixing cervix uteri.

This utility model is through facts have proved, more reasonable structure, and stable operation, little to vulneratio uteri, reduced wound area, shortened patient's recovery time, have more advance than prior art.
