Abstract
The utility model discloses a manual membrane breaker for obstetrics, belonging to the technical field of medical appliances. The manual membrane breaker consists of a sleeve, a sleeve cover, a slide block, a membrane breaking needle, a connecting rod, a limiting plate, a supporting spring and a handle, and is characterized in that the outer wall of an open end of the sleeve is in threaded connection with the sleeve cover, wherein the slide block which is matched with a cavity of the sleeve is slidably sleeved in the sleeve; the membrane breaking needle corresponding to a central hole at the bottom of the sleeve is fixedly connected on the front end of the slide block; the rear end of the slide block is connected with the limiting plate in the sleeve through the connecting rod; a supporting spring is connected between the limiting plate and the sleeve cover; and the two ends of the handle which is vertically fixed to the connecting rod penetrate through mutually symmetric axial through holes in the tube wall of the rear section of the sleeve to be exposed out of the sleeve respectively. The manual membrane breaker has the advantages of simple structure, convenience in use, high accuracy, high stability and capabilities of strictly controlling the size of a crevasse and relieving the difficulty during manual membrane breakage of an obstetrician.
Description
Technical field: this utility model belongs to the medical instruments technical field, specifically a kind of obstetrical apparatus for artificial rupture of membrane.
Background technology: at present, clinical obstetrics there is no special equipment when carrying out artificial rupture of membrane, and the obstetrician uses syringe needle or vascular forceps to carry out artificial rupture of membrane usually.When carrying out artificial rupture of membrane with syringe needle, syringe needle need be clamped in forefinger and middle interphalangeal enters vagina, its poor stability, and accuracy is not high, then can't operate during in 3 centimetres when the palace is young; When carrying out artificial rupture of membrane with vascular forceps, because of the vascular forceps limited length, the pincers top is more blunt, need clamp fetal membrane and tear, uncontrollable like this cut size, and one-time success rate is low, brings many difficulties for obstetrician's operation.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of obstetrician when artificial rupture of membrane, the obstetrical apparatus for artificial rupture of membrane that accuracy is high, stability is strong, can strictly control the cut size.
The purpose of this utility model is achieved in that this obstetrical apparatus for artificial rupture of membrane is comprised of sleeve, socket cover, slide block, membrane puncture needle, connecting rod, limiting plate, support spring, handle, sleeve opening end outer wall thread is connecting socket cover, sleeve inner is slided and is being set with the slide block that adapts with its inner chamber, be connected and fixed the membrane puncture needle corresponding with centre bore at the bottom of the sleeve cylinder above the slip front, the slide block rear end links to each other with limiting plate in the sleeve by connecting rod, is connected with support spring between limiting plate and the socket cover; Be vertically fixed on and be exposed at the sleeve outside after axially extending bore symmetrical above the sleeve back segment tube wall is passed respectively at handle two ends above the connecting rod.
During use, pull back handle and membrane puncture needle be retracted in the sleeve, then will withstand on the fetal membrane at the bottom of the sleeve cylinder, behind the loosening handle under the effect of support spring membrane puncture needle fetal membrane can be punctured.
Advantage of the present utility model: simple in structure, easy to use, accuracy is high, and stability is strong, can strictly control the cut size, has alleviated the difficulty of obstetrician when artificial rupture of membrane.
Description of drawings: accompanying drawing 1 is structure cutaway view of the present utility model.
The specific embodiment: be described in further detail below in conjunction with 1 pair of this utility model of accompanying drawing: this obstetrical apparatus for artificial rupture of membrane is by sleeve 1, socket cover 2, slide block 3, membrane puncture needle 4, connecting rod 5, limiting plate 6, support spring 7, handle 8 forms, sleeve 1 opening end outer wall thread is connecting socket cover 2, sleeve 1 slides within is being set with the slide block 3 that adapts with its inner chamber, be connected and fixed the membrane puncture needle 4 corresponding with centre bore at the bottom of 1 in the sleeve above slide block 3 front ends, slide block 3 rear ends link to each other by the limiting plate 6 in connecting rod 5 and the sleeve 1, are connected with support spring 7 between limiting plate 6 and the socket cover 2; Be vertically fixed on and be exposed at sleeve 1 outside after axially extending bore symmetrical above the sleeve 1 back segment tube wall is passed respectively at connecting rod 5 top handle 8 two ends.
