Definitions
- This invention relates to anal speculums for use by surgeons in the treatment of haemorrhoids .
- Prior known speculums for that purpose have comprised a tubular probe, for insertion into the anus, wherein a hole pierces the tube wall of the probe near its- front or leading end.
- a surgeon had to align the probe, before insertion, with a haemorrhoid to be treated and then insert the probe to a depth enabling access through the hole to the haemorrhoid in question. This has been an awkward procedure and requires retraction and reinsertion of the probe one or more times in the event that one or more further haemorrhoids require to be treated at the one treatment session.
- An object of the invention is to alleviate the objectionable features of the prior art speculums referred to above .
- the invention consists in an anal speculum of the kind comprising a tubular probe adapted to be inserted into the anus of a patient, characterised in that a leading end face of the tubular probe has two or more bights formed therein.
- a leading end face of the tubular probe has two or more bights formed therein.
- each such bight may be tapered to some extent, such that its side edges converge from a widest portion at the mouth of the bight.
- any haemorrhoid or swollen vein needing treatment within the ambit of the wide open, leading end of any bight is guided by one or other or both side edges of the bight to a position at or near the narrower trailing end of the bight, where it may be treated by injection or ligation.
- the probe is a disposable item, able to be easily fixed to a conventional handle.
- the probe may thus be discarded after a single use.
- it is preferably transparent to enable light from a light source constituting part of the handle to illuminate the bowel wall and inner anus, so as to provide good visibility for the surgeon.
- Figure 1 is a side elevation of an anal speculum according to the invention in combination with a handle and introducer.
- Figure 2 is a view similar to figure 1 of the combination of that figure with the tubular probe and introducer shown in longitudinal-section .
- Figure 3 is a side elevation of the speculum appearing in of Figure 1 drawn to an enlarged scale.
- Figure 4 is a longitudinal-sectional view of the speculum of figure 3.
- Figure 5 is a front end elevation of the speculum of Figure 3.
- Figure 6 is a rear end elevation of the speculum of figure 3.
- Figure 7 is a plan view of the speculum of figure 3
- Figure 8 is a longitudinal-sectional view of the introducer appearing in figure 1.
- Figure 9 is a side elevation of the introducer of figure 8 Best mode of carrying out the invention
- the combination illustrated by figures 1 and 2 comprises a speculum 10 according to the invention, an introducer 11 and a handle 12.
- the speculum 10 is a one-piece moulding of a rigid transparent plastics material. It comprises a tubular body 13 having a leading end 14, a trailing, flared skirt 15 and an optical conductor 16 extending as a cantilever from the skirt 15.
- leading end 14 has a leading end face characterised by three, in this instance slightly tapering, elongate bights 17 equiangularly spaced apart by tongues 18 of arcuate cross-section.
- those bights 17 are adapted to pick up haemorrhoids which are guided by the side edges of the tongues 18 into the narrower, trailing ends of the bights where they may be readily accessed by a surgeon through the skirt 15 and the bore of the tubular body 13 using well known and conventional surgical implements and procedures .
- an introducer 11 may be used, and the present invention includes such an introducer and its use in conjunction with the speculum.
- the introducer 11 comprises a tapered tube having a smoothly rounded leading end 19 pierced by a small vent hole 20 and art enlarged, open, trailing skirt 20 which (see figure 2), comes into abutment with the inner surface of the leading end of the skirt 15.
- the introducer 11 is dimensioned so that it may extend neatly through the speculum 10 until its rounded leading end 19 protrudes from the leading end of the speculum.
- insertion of the speculum through the anus may be effected by manual pressure on the protruding trailing end of the introducer 17. Once insertion has been accomplished the introducer 11 may be withdrawn from the inserted speculum for disposal or sterilisation and re-use.
- the handle 12 is a conventional item readily available from surgical instrument supply houses. It is in the nature of an electric torch, having a cylindrical body adapted to house replaceable batteries and a switch (not shown) in a circuit for the energisation of a small but high-powered light bulb.
- the bulb is disposed at the inner end of a cylindrical socket in an end of the handle into which the optical conductor 16 is a tight but manually separable fit.
- the conductor 16 may simply be thrust into the socket to enable the handle not only to function as such for manipulation of the speculum as a whole but also to provide illumination at the site of the haemorrhoids being treated.
