Description

Antiskid ring ware of getting that falls

Technical Field

The invention relates to the field of cervical instruments, in particular to an anti-slip ring extractor.

Background

In family planning, the intrauterine device is an effective, safe, economical and reversible contraceptive tool, and more than 60% of women of childbearing age adopt the intrauterine device for contraception in China, so the intrauterine device is a common contraceptive method for women of childbearing age. However, the use of an intrauterine device for contraception all the year round can cause the used women to have the phenomena of intrauterine device dislocation, vaginal pregnancy, menopause, complications and the like, and the intrauterine device needs to be taken out or replaced, so that the taking out of the intrauterine device is one of the common gynecological operations. The traditional ring taking method mostly adopts a ring taking hook, and the method can cause massive bleeding, ring taking failure and the like. In order to research the clinical effects of the multifunctional ring-removing forceps and the traditional ring-removing hook, the inventor of the inventor performs long-term research on the ring-removing case of the intrauterine device, and summarizes the experience and the results as follows:

because most of intrauterine devices used in China are T-shaped structures and the deformation thereof, the probes generally detect the depth of the uterine cavity along the uterine direction. After reaching the uterine fundus, the uterine cavity is withdrawn by 1 cm, and the attachment part of the contraceptive ring is searched on the back wall, the front wall or the side wall. Hooking the contraceptive ring (the amplitude is preferably small), slightly rotating left and right to enable the contraceptive ring to be gradually stripped, and then pulling out the contraceptive ring by probing.

Because the uterus is subjected to different physiological development and body positions, the shape of the bottom of the uterus is upwarped or pressed downwards, the hook position is generally in the top opening area of the contraceptive ring, when the uterus is pulled out to the cervical orifice, the bottom end of the rod body of the contraceptive ring is difficult to align with the cervical orifice, and the uterus is slightly pulled out after repeated trial by manipulation and experience. In the process, the bottom end of the rod body repeatedly stimulates the cervical orifice and nearby tissues, and the injury is easily caused under the condition of insufficient experience of manipulations or the condition that the cervical orifice of a patient is sensitive and the like.

Disclosure of Invention

The invention aims to provide an anti-slip intrauterine device extractor which can better fix a middle rod body of a contraceptive ring with a T-shaped structure and a similar structure, quickly and accurately pass through a cervical orifice, avoid repeated try and stimulation on the cervical orifice and nearby tissues, greatly reduce the probability of injury to women and improve the intrauterine device extracting operation level.

the mobile jib mechanism includes body 1, body 1 is hollow tubular structure, and the cross-section is waist shape, the outer wall of body 1 is fillet structure and no edges and corners, and whole appearance is mellow and full, does not harm comparatively soft organ tissue.

The front end of the tube body 1 is provided with a bullet-shaped guide head 2, and the bottom section of the guide head 2 can better cover the rear structure of the tube body, so that when the device enters the cervical orifice, no protruding component exists, and skin mucosa tissues are not stimulated. The front part of the tube body 1 is provided with an operation window 3 along the length direction, the inner side (the side provided with the operation window 3) of the waist-shaped structure is inwards sunken, internal components can be better hidden, and the two sides are round and smooth, so that the cervical orifice can be conveniently passed through.

(2) The auxiliary rod mechanism comprises a sliding rod 4, the sliding rod 4 is a sheet-shaped rod matched with the curved surface of the inner wall of the pipe body 1, the sliding rod 4 is sleeved in the pipe body 1 and is in sliding connection with the pipe body 1 along the length direction of the pipe body, the front end of the sliding rod 4 can be exposed in the operation window 3, the rear end of the sliding rod 4 penetrates out of the pipe body 1 and is provided with a control box 14, a second mounting port 16 is arranged on the control box 14, and a second gear 17 is rotatably mounted in the second mounting port 16,

slide bar 4 can slide from top to bottom along body 1, after this body 1 gets into the cervix, can visit behind the palace base position through guide head 2, the position of nimble adjustment eave tile mechanism, nimble control and adjustment operating position promptly, conveniently find the pole portion of contraception ring, slide from top to bottom through slide bar 4 that sets up inside, replace whole body 1 and adjust the removal from top to bottom, slide bar 4's upper and lower adjustment is in body 1, amazing and contact cervical orifice and cervical internal tissue, further reduce to the cervix, intrauterine stimulation, reduce injury in the art.

(3) The hook head mechanism is used for fixing the middle rod body of the contraceptive ring. The mechanism is unfolded relative to the sliding rod 4 in an initial state and is in a straight line with the sliding rod 4, so that the loop extractor is integrally provided with no protruding part, and can conveniently enter a cervical orifice, and after entering, the loop extractor can turn downwards to fix the rod body in a relatively wide environment of uterus.

The hook head mechanism comprises a connecting part 5, a hook rod 6 and a silica gel sheet 7,

the bottom side of the connecting part 5 is hinged with the front end of the sliding rod 4, the hook rods 6 are fixed on the connecting part 5 in a bilateral symmetry manner, a clamping groove is formed between the hook rods 6 and is used for clamping the middle rod body part of the T-shaped and deformed contraceptive ring, the silicon sheets 7 are fixed on the inner side of the hook rod 6, the front side of the silicon sheets 7 is provided with a fillet structure, the two silicon sheets 7 are mutually covered, the fillet structure at the front end forms a horn mouth shape, the horn mouth is arranged to facilitate the middle rod body of the contraceptive ring to enter the clamping groove, when the rod body enters, the control rod 8 is pulled down continuously to ensure that the hook mechanism continuously turns downwards, thereby make the silica gel piece 7 of both sides tightly embrace the middle part body of rod of centre gripping contraceptive ring, the centre gripping is fixed the effect stably, is difficult for droing, can be fine afterwards with the body of rod clamping of contraceptive ring in this one side of getting the ring ware to make the two form parallel structure. When the contraceptive ring is taken out in the next step, the contraceptive ring taking device penetrates through the cervical orifice and is taken out outwards, the rod body of the contraceptive ring can be driven to be taken out together, and the contraceptive ring is tightly attached and fixed on one side (the concave side) of the contraceptive ring taking device in parallel, so that the contraceptive ring can be well integrated with the contraceptive ring taking device to be smoothly aligned and pass through the cervical orifice, stimulation in repeated attempts is avoided, and the cervical orifice and nearby tissues are prevented from being punctured, so that injury is caused to an operator.

(4) The control rod mechanism, the control rod mechanism includes control rod 8, be equipped with fixed block 10 on the slide bar 4, be equipped with on the length direction of fixed block 10 along slide bar 4 and be used for making control rod 8 pass through and gliding slide opening, control rod 8 passes through slide opening and slide bar 4 sliding connection. The front end of the control rod 8 is hinged with a connecting rod 9, the front end of the connecting rod 9 is hinged with the front side edge of the connecting part 5,

thereby forming a channel penetrating from the rear end of the tube body 1 to the operation window 3 along the center line in the tube body 1 for placing the endoscope.
