SUMMARY OF INVENTION It is a general object of the present invention to provide a unitary disposable proctoscope which can be employed with a minimum of discomfort to the patient which improves substantially both visual and physical access tothe anus and lower rectum and which serves also as an external rectractor of perianal tissue.
The proctoscope of the invention is well suited to use in explorations of the rectum and anal canal and as an aid in the diagnosis and treatment of hemorrhoids, tumors, cryptitis and other anal-rectal disorders. Minor surgery in the lower portion of the rectum and anal canal can also be advantageously carried out with the aid of the proctoscope.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a top plan view of the improved proctoscope.
FIG. 2 is a side view of the proctoscope.
FIG. 3 is a rear view of the proctoscope.
FIG. 4 is a radial section taken generally as indicated at 4-4 in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring particularly to FIG. 1, it will be observed that an axially elongated body portion of the proctoscope has a front end portion 12 which is gradually arcuate for ease of insertion into an anal canal. At a rear portion 14, the body of the proctoscope carries a flange indicated generally at 16 and which extends generally radially outwardly from the body portion. A slot 18 extends axially within and along the axially elongated body 10 and is open rearwardly for use as a viewing slot. The bottom wall 20 of the slot 18 is preferably inclined so that the slot deepens graduallywhen viewed from front to, rear. At a front end portion 22, the bottom wall of the slot, terminating short of the front of the body portion 10,
tapers gradually forwardly and radially outwardly so as to provide gently blending surfaces.
As will be apparent, the gradual arcuate configuration of the front end portion 12 and the gradual areuate configuration of the wall 22 serve importantly in the minimization of discomfort to the patient. On insertion of the proctoscope, the front end portion 12 serves to reduce discomfort and, on withdrawal of the proctoscope, the gradually tapered portion 22 minimizes the likelihood of discomfort and of picking up mucus or other material.
The body 10 is generally circular in cross section and, in its presently preferred form, the body is substantially elliptical with the slot 18 opening through a section of lesser radius as best illustrated in FIG. 4.
The flange 16 extends circumaxiallyabout the rear portion 14 of the body of the proctoscope but terminates short of theslot 18. As mentioned above,the flange is relatively wide andas shown, the flange extends radially in all directions a distance at least twice the average radius of the body 10. In the radial direction opposite the slot 18, theflange extends from the body for a distance at least fourtimes the average radius of the body. Thus, the flange is considerably elongated in the direction opposite the slot 18 and curves gradually forwardly at aradial inner section 24 so as to blend smoothly with the body 10. Further, the junction or blending section 24 meets with the rear portion 14 of the body 10 and the gradual .reductionof cross section continues in a forward direction. That is, the body 10 tapers inwardly as viewed from the rear or; conversely, the body exhibits a gradual outward taper when the instrument is viewed from front to rear.
A handle 26 is preferably formed integrally at a rear surface of the flange 16 in the preferred embodiment of the proctoscope and the lower or bottom wall 20 of the slot 18 forms a top surface of the handle .26 at its rear end portion, FIG. 2. A small axially extending and upwardly open groove 28 is formed in said surface in accordance with the presently preferred practice for use as a guide for an operating or other instrument. That is, a comparatively long instrument may be entered in the groove for guidance and for ease in manipulation of its forward end.
It will be apparent from the foregoing that the flange 16 is of a configuration well adapted for use as anexternal rectractor for perianal tissuesuch that the tissue may be easily displaced in carrying out minor surgery. A completely open viewing area is provided with the flange 16 and the slot 18 for ease of viewing and access to the perianal area, the anal verge, the hemorrhoid bearing area and the lower rectum. The handle 26 provides for ease in manipulation, removal and re-insertion of the instrument and it is apparent that the instrument may be readily used with one hand leaving the other hand free for a surgical instrument. As mentioned, the proctoscope of the present invention is preferably constructed of plastic or other materialfor disposable use and a plastic having a dull finish is to be desired for minimum light reflection during use.
