Definitions
- This invention relates to a medical instrument for use in amniotomy.
- a medical instrument for use in amniotomy comprising a locating member for locating the instrument on an operator's .finger and a cutting member affixed to the locating member.
- the locating member is in the form of a sleeve which fits over the operator's finger.
- the sleeve is preferably closed at the end to form a seal over the end of the operator's finger, and most preferably the sleeve is of a length sufficient to envelop the finger to below the first joint.
- the sleeve is formed from a flexible material such as latex or a plastics material.
- the cutting member is a hook of plastics material such as polystyrene.
- the cutting member may be of a different material from the locating member and is preferably more rigid than the locating member.
- the cutting member is disposed on the locating member so as to be on the ball of an operator's finger in use; this provides for maximum sensitivity.
- the cutting portion of the cutting member is disposed in a direction towards the palm of the operator's hand in use.
- the cutting member is affixed to the sleeve by adhesive.
- the locating member may be in the form of a finger cot or may form a finger of a glove, for example the middle or index finger.
- a method of amniotomy comprising locating a cutting device on an end portion of an operator's finger, inserting the finger through the cervix of a patient, positioning the cutting device adjacent the membranes of the patient and cutting the membranes with the cutting device.
- Fig. 1 is a perspective view showing a first embodiment of a medical instrument for use in amniotomy in accordance with the present invention
- Fig. 2 is a perspective view showing a second embodiment of a medical instrument for use in amniotomy in accordance with the present invention
- Fig. 3 is a view showing the medical instrument of Fig. 1 in amniotomy.
- Fig. 4 is a view showing a further embodiment of a medical instrument of the present invention in use.
- a medical instrument for use in amniotomy comprises a latex sleeve 1, open at the end and having a length and internal diameter selected to allow it to fit tightly over the length of an operator's finger 2, and having a polystyrene hook 3 on its end portion.
- the hook 2 projects from a disc 5 of polystyrene which is bonded to the latex sleeve 1 with "superglue" adhesive.
- the polystyrene of the disc 5 and hook 3 is substantially rigid while the latex of the sleeve 1 is highly flexible.
- the open end of the sleeve 1 is provided with an annular ring 4 of slightly thicker material which the operator may roll along his finger 2 when he wishes to apply or remove • the sleeve 1.
- annular ring 4 of slightly thicker material which the operator may roll along his finger 2 when he wishes to apply or remove • the sleeve 1.
- the sleeve 1 being positioned such that the disc 5 is situated on the ball of the operator's .finger 2 with the hook 3 directed towards the palm of the hand.
- the finger 2 is then inserted through the cervix 6 and the hook 3 guided to the appropriate area in order to rupture the membranes 7.
- Fig. 2 shows a further medical instrument of the invention where the latex sleeve 1 forms the index finger of a moulded glove 10, and in this case the glove 10 can be applied in preference to routine gloves for elective amniotomy.
- Fig. 4 shows a further embodiment of the present invention in use.
- This embodiment features a hook 3 which is pointing in the opposite direction to that of the hooks 3 of Figs. 1 and 2, and in this case the membranes 7 are ruptured by movement of the hook 3 away from the operator.
