Abstract
The utility model relates to a replacement-free dilating bar, which comprises a body. The front of the body presents a conical bent shape, a cavity is arranged inside the body, the front half portion of the cavity is of a conical shape, the rear end of the body is provided with a handle clamped at the rear end of the cavity, and the outer end of the handle is provided with a bolt connected with an expansion device inside the cavity. When in use, an operator inserts the front end of the body into a cervical opening, and slowly rotates the bolt to push the expansion device to move forwards gradually, then the body at the cervical opening gradually expands to gradually open the cervical opening, and the body is withdrawn after requirement is met, thereby avoiding injury on a patients' bodies caused by multiple times of expansion bar replacement and having convenient utilization. The replacement-free dilating bar made of high molecular materials has the advantages of smoothness, fine resilience, low cost, no replacement, disposability to avoid cross infection and the like.
Description
Technical field
This utility model relates to a kind of medical supplies, especially a kind of free of replacement uterine-expanding rod.
Background technology
At present, the inspection of gynecological's hysteropathy and treatment, for example: dilatation and curettage, the clearing heat in the pericardium, uterine cavity radiotherapy, artificial abortion etc., all need expansion cervix, the process of expansion cervix is slowly carried out, existing cervical dilator be tree root oval head, work surface diameter from 4mm to the 10mm stainless steel round bar, to put into cervical orifice successively from fine to coarse during use, make its way that enlarges gradually carry out Cervical expansion.This way needs a plurality of different-diameter metal cervical dilators aligning cervix uteri mouths to insert and extract, medical worker's complex operation, and length consuming time causes cervix uteri damage and patient's fear easily.
In addition, Chinese patent ZL00267436.X discloses a kind of disposable cervix dilator, it adopts the difform paragraph of more piece to form, can once complete Cervical expansion, but because structural limitations, its length generally can be long, inconvenient operation, and restive, the cervix uteri to the patient causes damage easily.
Chinese patent ZL99219123.8 discloses a kind of disposable continuous cervical dilator, it adopts the more piece cylinder of different-diameter to be sleeved on together, draw ring by each joint afterbody stretches and regulates the purpose realize cervical dilatation, but it operates more complicated, and be difficult to control, use inconvenient.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, avoid repeatedly changing, the patient being damaged little free of replacement uterine-expanding rod.
For achieving the above object, this utility model adopts following technical proposals:
A kind of free of replacement uterine-expanding rod, it comprises barred body, the barred body front portion is circular cone bending shape, be provided with cavity in the barred body, the first half of described cavity is tapered, and the rear end of barred body is provided with the handle that is stuck in its cavity rear end, and the outer end of handle is provided with the bolt that links to each other with expansion gear in the cavity.
Described expansion gear comprises ball and connecting rod, and ball is arranged in the conical cavity, is provided with a passage in the handle, with the passage of barred body contact jaw be unthreaded hole, the other end is a silk hole, is provided with a cavity between unthreaded hole and thread hole, silk is rotary with bolt in the hole, and bolt links to each other with ball by the connecting rod that passes unthreaded hole.
During use, the barred body front end is inserted in the cervix uteri mouth, swivel bolt slowly then, promoting ball progressively advances, the barred body of cervix uteri oral area position is expanded gradually, the cervix uteri mouth is opened, barred body is extracted out after reaching requirement, avoid repeatedly changing the injury that dilator bar causes patient body, and easy to use.This utility model adopts medical macromolecular materials to make, and has that smooth, good springiness, cost are low, free of replacement, disposable use avoid advantages such as cross infection.
Description of drawings
Fig. 1 is this utility model structural representation;
1. barred bodies wherein, 2. cavity, 3. ball, 4. connecting rod, 5. handle, 6, bolt.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
Among Fig. 1, barred body 1 front portion is circular cone bending shape, is provided with cavity 2 in the barred body 1, and the first half of described cavity 2 is tapered, and the rear end of barred body 1 is provided with the handle 5 that is stuck in its cavity 2 rear ends, and the outer end of handle 5 is provided with the bolt 6 that links to each other with expansion gear in the cavity 2.
Described expansion gear comprises ball 3 and connecting rod 4, ball 3 is arranged in the conical cavity 2, be provided with a passage in the handle 5, with the passage of barred body 1 contact jaw be unthreaded hole, the other end is the silk hole, be provided with a cavity between unthreaded hole and the silk hole, silk is rotary with bolt 6 in the hole, and bolt 6 links to each other with ball 3 by the connecting rod 4 that passes unthreaded hole.
During use, barred body 1 front end is inserted in the cervix uteri mouth, swivel bolt 6 slowly then, promoting ball 3 progressively advances, the barred body of cervix uteri oral area position is expanded gradually, the cervix uteri mouth is opened, reach after the requirement barred body 1 is extracted out, avoided repeatedly changing the injury that dilator bar causes patient body, and easy to use.
