Abstract

The invention relates to a kidney-shaped elastic rectoscope which is a rectoscope applied to surgery, check, medicine injection and the like of the rectum and the sigmoid flexure. A rectoscope body of a traditional rectoscope is a straight-cylinder-shaped circular tube and made of non-elastic materials, so that when the traditional rectoscope is used, the traditional rectoscope must be fixed by external force and is inconvenient to use. The kidney-shaped elastic rectoscope is made of elastic high-polymer materials. A whole rectoscope body is a kidney-shaped circular tube with the middle portion thin and the two ends thick, the upper portion of the rectoscope body is a long straight-cylinder-shaped circular tube, the middle of the rectoscope body is a thin kidney-shaped circular tube, and the lower portion of the rectoscope body is a short straight-cylinder-shaped tube or a trapezoid circular tube. The rectoscope can be folded and placed in the rectum and after the folded rectoscope is placed in the rectum, the rectoscope can be restored to the kidney-shaped tube through the elasticity and expansion through appropriate external force. The rectum is expanded by the upper portion of the rectoscope, the anus is expanded by the middle portion, and the rectoscope is held and fixed through the anal sphincter, fixation through the external force is not needed, and use is convenient. The kidney-shaped elastic rectoscope is suitable for the processes of endoscopic surgery, taking out of a sample, check, medicine injection and the like conducted for a rectum sigmoid flexure disease or conducted in the anorectum.

Description

Kidney-shaped elasticity rectoscope

Technical field

The present invention relates to a kind of kidney-shaped elasticity rectoscope, is a kind of for rectum and operation on sigmoid and the rectoscope used such as inspection, dabbling drug.

Background technology

Traditional PROCTO mirror body is straight tube shape pipe, adopts the materials such as inelastic metal, plastics, glass to make, and the expansion amplitude of rectum and the expansion amplitude of anus are consistent, during for examination per rectum, must fix by external force such as hands or apparatuses, is not easy to use.

Beginning in the 2010's, per anum rectum carries out " natural tract endoscopic surgery " or " natural tract taking-up specimen ", more traditional laparoscopic surgery is Wicresoft more, main body or the important component part of internal organs resection operation in knot rectum and other abdomens will be become, its instrument adopting take " per anum microsurgery system " be representative, the rectoscope body using remains traditional straight tube shape pipe, and the metals that adopt are made more, need separately with support, to fix, be very inconvenience, and expensive, increased patient's financial burden.Therefore, need a kind of novel rectoscope of research badly, can either meet above emerging operation needs, alleviate operator operation burden, simultaneously cheap again, alleviate patient economy burden.

Summary of the invention

The object of the present invention is to provide a kind of easy to use, without external force fix, cheap kidney-shaped elasticity rectoscope.

To achieve these goals, the technical solution used in the present invention is as follows: kidney-shaped elasticity rectoscope, and adopt resilient macromolecular material to make, cheap, can disposablely use; Its mirror body integral body is the thick middle thin kidney-shaped tubulose in two, and top is long straight tube shape pipe, and middle part is eel-like figure shape pipe, and bottom is short straight tube pipe or trapezoidal pipe.This mirror can be folding along longitudinal axis before inserting rectum, insert after rectum due to former and flexiblely add that suitable external force expansion can revert to kidney-shaped, upper minister's straight tube shape pipe expansion rectum, eel-like figure expansion anus in middle part is also held with a firm grip fixingly by anal sphincter, the short straight tube pipe in bottom or trapezoidal pipe are used for strutting perianal tissue and assist fixing.Each portion forms an integral body above, and working place is provided jointly.The amplitude of this mirror expansion rectum is greater than the amplitude of expansion anus, is applicable to per anum internal rectum videoendoscopic surgery, takes out specimen, inspection, injection etc.

Accompanying drawing explanation

Fig. 1 is elasticity kidney-shaped rectoscope front view.

Fig. 2 is elasticity kidney-shaped rectoscope top view.

Fig. 3 is the top view after elasticity kidney-shaped rectoscope folds along longitudinal axis.

The specific embodiment

During use, first elasticity kidney-shaped rectoscope is folding along the longitudinal axis of Fig. 1, area with diameter reduction direction, top view schematic diagram after folding as shown in Figure 3, elasticity kidney-shaped rectoscope after folding is inserted in anal orifice and rectal intestine, rectoscope flexiblely adds that the expansion of suitable external force can revert to the kidney-shaped shown in Fig. 1 due to former, suitably adjust PROCTO position, kidney-shaped expansion anus in the middle of making, by anal sphincter, held with a firm grip fixing, upper minister's straight tube shape pipe expansion rectum, middle part eel-like figure expansion anus is also held with a firm grip fixing by anal sphincter, the short straight tube pipe in bottom or trapezoidal pipe are used for strutting perianal tissue and assist fixing.Each portion forms an integral body above, jointly provide appear, the working place such as biopsy, separation, excision, taking-up specimen, be applicable to for proctosigmoid pathological changes or per anum rectum approach carries out endoscopic surgery, takes out specimen, inspection, injection etc., especially per anum rectum approach carries out endoscopic surgery and takes out specimen.

Claims (1)

1. kidney-shaped elasticity rectoscope, it is characterized in that: rectoscope is the thick middle thin kidney-shaped in two, employing elastomeric material is made, can be folding along axis direction before inserting rectum, automatically revert to kidney-shaped after inserting rectum, rectoscope top is long straight-tube shape pipe, be used for expanding rectum, middle part is used for expanding anus for eel-like figure shape pipe, and it is fixing by anal sphincter, to be held with a firm grip, and the short straight-tube shape in bottom or trapezoidal pipe are used for strutting perianal tissue and assist fixing.
