Description

A kind of uterine myomas crow bar

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of uterine myomas crow bar.

Background technology

Hysteromyoma is modal a kind of benign tumor in female sex organ, is also one of modal tumor in human body, is common in 30 ~ 50 years old women, and sickness rate is 50%-70%.Along with the raising of clinical levels, retaining reproductive function and reducing wound as far as possible becomes clinician and the maximum focus of patient.

The Therapeutic Method of common hysteromyoma has Drug therapy, operative treatment, focused ultrasound therapy.Wherein uterine myomas operation not only can retain the fertility of patient, the more important thing is the physiological function that can maintain uterus, keep the integrity of anatomical structure at the bottom of basin, minimum on the impact of hypothalamic-pituitary-ovarian-uterine axis, being conducive to the physical and mental health of patient, is hysteromyoma first-selection, conventional iatrotechnics formula.

Myomectomy can carry out through abdomen or through peritoneoscope.Traditional abdominal wound is large, intraoperative blood loss is more, large to the interference of pelvic cavity environment, infection rate is high, gastrointestinal function recovers slower.In recent years, along with improving constantly of laparoscopic operation techniques, laparoscopic myomectomy is carried out clinically in succession, the advantages such as laparoscopic surgery has that wound is little, otch is attractive in appearance, little to organismic internal environment interference, fast, the postoperative pelvic adhesion of few intercurrent disease, post-operative recovery is few, gradually by extensive patients and clinicist accept.

Laparoscopic surgery is the operation of apparatus dependency, and the operating theater instruments that current Laparoscopic Myomectomy uses comprises high frequency electric knife, tissue shear, muscular tumor brill and ultrasound knife.Being most widely used wherein with high frequency electric knife, comprise list, bipolar coagulation, its working mechanism's core is that coagulation and TURP are carried out in the pyrolytic damage effect utilizing electric current to be produced by body, but in use producing a large amount of smog, to cause surgical field of view fuzzy, need constantly smoke evacuation, so that operating time extends, and containing a large amount of toxic gas in smog, mainly contain carbon monoxide, Blausure (German), acrylonitrile and benzene etc., and heat effect is obvious, produce 100 ~ 400 DEG C of high heat, can damage 15mm surrounding tissue, easy generation electric injury, particularly can damage contiguous muscle layer tissue, affect organization healing, especially for nullipara and have fertility claimer, as affected postoperation recovery, again uterine rupture can be there is during gestation.Tissue shear is also that the one divesting muscular tumor commonly uses operating theater instruments, but muscular tumor tissue can only little by little take out by it, and length consuming time in art, cost is high.Muscular tumor bores front end easy fracture in use, difficult and time-consuming to the muscular tumor taking-up of more than diameter 6cm.Only produce little water droplet in ultrasound knife use procedure and do not produce smog, surgical field of view is clear, and hot injury is little, without electric injury, but it is expensive, and it is slow to operate in operation, can only cut and solidifying contact with it and have the tissue of some tension, and can not cut too many tissue at every turn, the operation used time is longer.

In order to solve the above-mentioned defect that prior art exists, this utility model have developed a kind of crow bar being exclusively used in uterine myomas.

Summary of the invention

This utility model is to solve the above-mentioned deficiency used at present in uterine myomas process under existing peritoneoscope existing for apparatus, and provides a kind of uterine myomas crow bar.

This utility model is achieved through the following technical solutions:

A kind of uterine myomas crow bar, is made up of excellent handle, barred body, buffer joint and the caput set gradually from top to bottom; Wherein said caput is cone, and length is 20-35mm, diameter by 0 smooth transition at tip to 3mm; Described buffer joint is round platform, and length is 10-15cm, diameter by 3mm smooth transition to 5-6mm; Described barred body is the cylinder of length 250-310mm, diameter 5-6mm; Described excellent handle is the cylinder of length 120-150mm, diameter 13-20mm.

Further, described caput is cone, and length is 20mm or 35mm, and during operation, caput tip is easy to enter muscular tumor tumor body, in time, easily, conveniently adjustment to penetrate position, can have very high degree of freedom, another separable tumor wall; When tumor is comparatively large, as the crow bar that 10-12cm tumor can be grown with most advanced and sophisticated 35mm; Little muscular tumor for 5-9cm can select the crow bar at 20mm tip.

The cone of described caput, diameter by the 0.2mm smooth transition at tip to 3mm, caput tip is slightly blunt, both can avoid penetration damage, and crow bar can be avoided again to pass tumor bulk damage surrounding tissue, described barred body length 250-310mm, diameter 5-6mm, be the node of crow bar transition from fine to coarse, as the fulcrum of puncture muscular tumor, prevent puncture excessively; On the other hand, by increase rubbing action fix tumor body, can with tumor body close contact more, tumor body is fixed better, prevents slippage, be beneficial to when prizing muscular tumor play leverage.

Described excellent handle surface straight line wire drawing, is easy to grip, is beneficial to operator and crow bar is inserted tumor body, and then implements to be separated, to prize tumor body.

This utility model designs according to hysteromyoma distinctive " pseudocapsule " histological characteristic, after separator well " pseudocapsule " level, caput is stretched into muscular tumor in art can fast muscular tumor be separated with flesh wall, have easy to operate, quick, go out insufficiency of blood, non smoke, without electric injury, the feature not damaging uterus muscle fiber and adjacent tissue, muscular tumor can be picked out second by general 20-30; Be particularly useful for the hysteromyoma of gestation more than 12 weeks sizes and wish to retain reproductive function person, effective, go out insufficiency of blood, operating time is short, be easy to wound healing after operation, the chance broken in pregnant cicatrix place can be reduced again, largely decrease misery and the surgical operation of patient.

Compared with prior art, this utility model is simple to operate, easy to clean, cheap, can repeated disinfection and repeatedly using, can in clinical wide popularization and application.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

1-caput, 2-barred body, 3-rod handle, 4-buffer joint in figure.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

A kind of uterine myomas crow bar as shown in Figure 1, is made up of the excellent handle 3 set gradually from top to bottom, barred body 2, buffer joint 4 and caput 1; Wherein said caput 1 is cone, and length is 20-35mm, diameter by 0 smooth transition at tip to 3mm; Described buffer joint 4 is round platform, and length is 10-15cm, diameter by 3mm smooth transition to 5-6mm; Described barred body 2 is the cylinder of length 250-310mm, diameter 5-6mm; Described excellent handle 3 is the cylinder of length 120-150mm, diameter 13-20mm.

Wherein, the diameter of caput 1 preferably by the 0.2mm smooth transition at tip to 3mm; Barred body is the surperficial straight line wire drawing of excellent handle 3, is easy to grip.
