Abstract

The utility model belongs to the field of medical devices, and relates to a hard anoscope applied to an anus surgery, particularly to the hard anoscope applied in a procedure for prolapse and hemorrhoids (PPH). The hard anoscope consists of an external ring and a neck, and is made of hard plastic materials; the appearance of the hard anoscope is I-shaped; the anoscope not only maintains the outer ring arranged in the range with an angel of 45 DEG on the outer side of the anoscope in the prior art so as to provide convenience for holding and fixing the anoscope, but also avoids the deficiency that the placing depth of the prior circular anoscope is insufficient. The hard anoscope has the advantages of simple and convenient operation, satisfied placing depth and good exposing effect, can avoid the influence of ischial tuberosities on two sides of an anus, provides excellent basis for the surgery, and is particularly suitable for various anus surgeries including the PPH.

Description

A kind of hard anoscope

Technical field

This utility model belongs to medical instruments field, relates to the hard anoscope that is applied to operation on anus, is specifically related to a kind of hard anoscope that is applied to mucosa circular resection stitching art on the anastomat hemorrhoid.

Background technology

Hemorrhoid are anus pad pathologic hypertrophys, move down the agglomerate that forms with crissum veins beneath the skin clump stasis of blood stream, can be with symptoms such as hemorrhage, prolapsus.According to China's statistical data in 2003, hemorrhoid account for the 12591 routine anorectal prescription on individual diagnosis patients' of section 64.42%, are a kind of commonly encountered diseases, frequently-occurring disease.Since Thompson in 1975 at first proposes " the anus pad moves down theory ", the treatment idea of hemorrhoid is brought in constant renewal in, especially the surgeon Dr Antonio Longo of Italian Palermo university in 1998 at first treats hemorrhoid in Rome with anastomat, for a new era has been started in the treatment of hemorrhoid.The whole world has totaled mucosa ring cutting art on the anastomat hemorrhoid (procedure for prolapse and haemorrhoids, PPH or stapled hemorrhoidectomy) 150,000 examples at present.

Professor Yao Liqing of mountain hospital introduces the PPH technology from Singapore in 20 days July in 2000, becomes second country that carries out this operation in Asia, prior to 1 year of the U.S..Along with the anus pad is moved down improving constantly of theory acceptance level, the amount for surgical of PPH increases year by year, and it is inferior that national total amount for surgical of carrying out surpassed 50,000 examples by 2008.

The principle of PPH operation is to use mucous membrane of rectum circular resection one circle of anastomat with the prolapsus of anus pad top, to reach the anus pad is resetted, and the blocking-up inferior rectal artery supplies for the blood of anus pad.The operating theater instruments that this operation is at present adopted comprises: 33mm anastomat (HCS33), hold line device (ST100), anal canal dilator (CAD33) and anoscope (PSA33).Wherein anoscope (PSA33) is the transparent configuration of a circle, is made by hard plastics, is made of the high 4CM of cervical region wherein, diameter 2.5CM cervical region and outer shroud; Outer ring width 1.5CM with 15 ° of angles of cervical region formation degree, is hollow structure at 0,3,6,9 respectively, is beneficial to the fixing of anoscope.During operation, the cervical region of PSA33 is inserted in the anal canal, generally requires its upper limb to surpass pectinate line 1 ~ 2CM, to finish the committed step of operation: sew up 2 ~ 3CM, one circle mucous membrane of rectum on the pectinate line.

But, because male's physiological feature: pelvis is less, the outer shroud of anoscope (PSA33) is owing to be subjected to the restriction of both sides ischium width, make the cervical region of PSA33 can't be presented to the satisfied degree of depth, the upper limb of patient who has even anoscope cervical region can't surpass pectinate line, 2 ~ the 3CM on pectinate line that can't reach requirements of operation sews up the rectal mucosal requirement of a circle, has influenced finishing of operation, causes patient's misery.

Summary of the invention

The purpose of this utility model is the defective that overcomes prior art, and a kind of " I " is provided the anoscope of font.

This utility model improves the anoscope (PSA33) of prior art, remove the transparent outer shroud of each 135 degree scope of both sides at the outer shroud of PSA33, keep and each 45 anoscope outer shroud of spending scopes of 6 two places at 12, outer shroud and cervical region are 15 ° of angles, the anoscope of " I " font after the improvement is inserted the influence that can avoid the both sides ischial tuberosity behind the anal canal, anoscope can be inserted the satisfied degree of depth, for operation provides good basis.

This utility model " I " font anoscope is made of outer shroud 1 and cervical region 2, adopts hard plastics to make, the high 3.8-4.2CM of cervical region, preferred 4CM, diameter 2.3-2.7CM, preferred 2.5CM; Outer ring width 1.4-1.6CM, preferred 1.5CM, 3 and nine o'clock spot respectively keep 45 degree scopes, are 15 ° of angles with cervical region, make the anoscope outward appearance be " I " font.

Clinical Practice proves, the utlity model has following remarkable advantage:

1. the outer shrouds that kept each 45 degree scope of the former anoscope outside, do not influence original design be used to perform the operation control function with fixed anoscope outer shroud.

2. " I " font anoscope is placed 12 of KC positions and 6 points during operation technique, avoided stopping of 3 and 9 ischials tuberosity in KC position, avoided the not enough deficiency of original circular anoscope placed-depth.

The outer shroud that this utility model had both kept each 45 degree scope of the former anoscope outside is beneficial to control and fixed anoscope, has avoided the not enough deficiency of original circular anoscope placed-depth again.Easy and simple to handle, appear effective.Be particularly useful for comprising the various operation on anus of mucosa circular resection stitching art on the anastomat hemorrhoid

Table 1 is the comparison of prior art (PSA33) and " I " font anoscope.
