The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Uterine cavity of the present invention struts in the following manner to be realized: the guide rod head is a cube structure, and cube both sides opposite is gradient to be 60 ° to 75 ° burr, and the gripper shoe inner surface connects a thin plate simultaneously, and thin plate is carved with the groove of same slope; When gripper shoe does not strut; Form an oval structures with U type tube head, the thin plate in the gripper shoe is inserted in the flat recess of U type tube head, when guide rod upwards promotes; Its surperficial burr docks with gripper shoe thin plate groove; Form the inclined-plane transmission, gripper shoe struts along the flat recess both sides in the process of on guide rod, moving, and reaches the purpose that struts uterine cavity.
Above-mentioned burr and groove through carrying out suitable surface treatment, obtain ideal skin-friction coefficient in transmission process, can realize self-locking: promptly gripper shoe down can not automatic drawing back at the active force of uterine cavity compressing, needs move through guide rod to realize the gripper shoe withdrawal.
Endoscope system is realized in the following manner: be provided with groove in U type tube head both sides, minisize pick-up head and the lighting source that has translucent cover is installed respectively, power supply and data wire are drawn through U type pipe lower cavity; After gripper shoe struts uterine cavity, outside U type tube head is exposed to, open the endoscope system power supply this moment, lighting source illumination uterine cavity is inner, and minisize pick-up head is spied on.Because the patient is the posture that lies low in operation, this moment, the uterus was closed up and down, and when gripper shoe strutted, the top gripper shoe can form natural protection to endoscope system, prevented that effectively in utero bloodstain covers surface of camera head.
Above-mentioned endoscope system is only explained minisize pick-up head and lighting source installation site and fixture, does not comprise the invention of photographic head and lighting source itself.
Referring to Fig. 1-4, the uterus that is used for visual artificial abortion provided by the invention struts and endoscope and image processing device, and this device cooperates negative pressure straw and minisize pick-up head to use, and this device comprises:
Support unit, this unit comprise the first gripper shoe 10a and the second gripper shoe 10b that is oppositely arranged and connects, and guide rod device 20, the first gripper shoe 10a and the second gripper shoe 10b form the space of hollow;
First head of guide rod device 20 is connected with the inner surface of the first gripper shoe 10a and the second gripper shoe 10b respectively;
The first thin plate 11a is positioned at the inner surface of the first gripper shoe 10a, links to each other with the head of guide rod device 20; This first thin plate 11a comprises first lower wall that links to each other with the first gripper shoe 10a; First upper wall that is oppositely arranged with this first lower wall; The first side wall that first lower wall is connected with first upper wall is provided with first groove that gradient is the 60-75 degree at the first side wall near the surface of guide rod device 20 heads;
The second thin plate 11b is positioned at the inner surface of the second gripper shoe 10b, links to each other with the head of guide rod device 20; This second thin plate 11b comprises second lower wall that links to each other with the second gripper shoe 10b; Second upper wall that is oppositely arranged with this second lower wall; Second sidewall that second lower wall is connected with second upper wall is provided with second groove that gradient is the 60-75 degree at second sidewall near the surface of guide rod device 20 heads;
Said pipe guide 30 heads one end opening; The other end links to each other with the middle part; The head of this pipe guide 30 be provided with upper surface 31, with this upper surface 31 lower surface that is oppositely arranged and the side that upper surface 31 is connected with lower surface; On upper surface 31 and lower surface, be respectively equipped with at least one groove, 32, the first thin plate 11a and the second thin plate 11b inserts respectively in this groove, the middle part 33 and the afterbody of pipe guide 30 are hollow circular cylinder.
As shown in Figure 1, the whole endoscope and image processing device that struts is by two gripper shoes (the first gripper shoe 10a, the second gripper shoe 10b), and 30, guide rods of a U type pipe 20 constitute.Gripper shoe is initially closure state, forms an oval structures with the U type head of U type pipe, and leader casing is in U type pipe, and afterbody exposes, and its head surface burr 21 matches with gripper shoe groove 11.Fibre-optical probe and illuminator are installed in the U type tube head groove 33.
In the operation, adopt earlier cervical dilator that the cervix uteri mouth is enlarged,, get into uterine cavity the cervix uteri mouth of this device for spreading through enlarging, control well simultaneously the gripper shoe opening towards, conform to the uterus inwall.After treating that ogival nose gets into uterine cavity fully, slowly promote guide rod, make its control gripper shoe strut Uterus wall, open video system simultaneously, watch image; After can clear observation, stop to promote guide rod, the buckle 23 of guide rod afterbody is stuck in the U type pipe afterbody groove 34, prevent that the guide rod maloperation from causing the uterus excessively to strut.The guide rod inner hollow can connect negative pressure equipment with the inner secretions sucking-off of uterine cavity, perhaps directly inserts the dilatation and curettage device, on one side the interior picture of observation chamber, selectively pregnant lens capsule tissue in the uterine cavity is scraped on one side and got, and outside the sucking-off palace.
Behind the pregnant capsule of sucking-off, guide rod buckle and U type pipe are unclamped, slowly extract guide rod out, and observe video system, guarantee that gripper shoe is closed smoothly.After treating two complete closures of gripper shoe, form oval structures again, slowly extract whole device out, accomplish operation with U type tube head.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
