背景技术Background technique
肛肠科疾病主要指肛门、直肠、结肠的各种疾病，常见的肛门直肠病有内痔、外痔、肛裂、肛瘘、肛门直肠脱垂、直肠息肉、直肠前突等；结肠病有溃疡性结肠炎、结肠息肉、结肠憩室炎、结肠肿瘤等。Anorectal diseases mainly refer to various diseases of the anus, rectum, and colon. Common anorectal diseases include internal hemorrhoids, external hemorrhoids, anal fissure, anal fistula, anorectal prolapse, rectal polyps, rectocele, etc.; colon diseases include ulcerative colitis , Colon polyps, colon diverticulitis, colon tumors, etc.
现有技术的扩肛器座是肛肠科手术的一种常用辅助器械，其在肛肠科检验、手术治疗过程中发挥着重要的作用。目前较为普遍采用的扩肛器座是一个带有边缘的直筒状结构，其边缘被医生控制或者是直接与肛门边缘的皮肤缝合固定。扩肛器座的作用是撑开肛门，为后续的检查或者治疗做准备。但是，这种结构的器械其功能很单一，为了便于手术的使用，其还需要配合肛镜等其他的手术器械进行手术。然而在使用中发现，现有的肛镜没有与扩肛器配合的固定结构，在手术过程中，医生将肛镜转动一定角度后，需要助手帮忙扶住肛镜才能进行打荷包，使用非常不方便。The anal dilator seat of the prior art is a commonly used auxiliary device for anorectal surgery, and it plays an important role in anorectal examination and surgical treatment. The anal dilator seat generally adopted at present is a straight cylindrical structure with edges, and its edges are controlled by a doctor or fixed directly with the skin of the anal edge. The function of the anal expander seat is to open the anus and prepare for the follow-up examination or treatment. But its function of the instrument of this structure is very single, in order to facilitate the use of operation, it also needs to cooperate other surgical instruments such as anoscope to carry out operation. However, in use, it was found that the existing anoscope does not have a fixed structure that cooperates with the anal expander. During the operation, after the doctor rotates the anoscope at a certain angle, an assistant needs to help the anoscope to hold the anoscope, which is very uncomfortable to use. convenient.

The anal dilator 1 includes a body composed of a distal end and a proximal end. The anal dilator 1 can pass through the anus to reach the surgical operation site. The distal end of the body is a cylindrical structure, of course for easier access In the patient's body, the distal end of the body can also be in the shape of a cone. The proximal end of the body is a suture connection part, and the suture connection part is a wide side 5 with a diameter larger than that of the main body, and the wide side 5 is divergent backward. In this embodiment, there are four hollow structures 6 evenly distributed on the surface of the wide side. The hollow structure is equidistantly distributed on the wide side to facilitate the suture of the wide side and the skin. Furthermore, a circle of wavy protrusions can be provided on the outer peripheral surface of the wide side, which can effectively prevent the doctor from slipping when grasping the auxiliary device of the present invention, and ensure that the wide side has a certain friction force.
所述肛镜2与所述扩肛器1间设有相互配合的固定结构，所述固定结构包括设置于所述肛镜背部的卡勾7，所述肛镜2经卡勾7固定连接于所述扩肛器1上，具体参见图1、2所示，手术时所述卡勾7卡在所述扩肛器1的宽边5上。The anoscope 2 and the anal dilator 1 are provided with a fixed structure that cooperates with each other. The fixed structure includes a hook 7 arranged on the back of the anoscope, and the anoscope 2 is fixedly connected to the anus through the hook 7. On the anal dilator 1 , referring to FIGS. 1 and 2 for details, the hook 7 is stuck on the wide side 5 of the anal dilator 1 during the operation.
实施例二：具体参见图3至6所示，本实施例中优选的一个技术方案，与实施例一的区别在于：所述肛镜2背部开设有定位凸台3，与所述定位凸台3配合在所述扩肛器1的宽边5上对应开设有多个相互间隔的定位孔4，定位凸台3卡进定位孔4内构成所述肛镜与所述扩肛器间的相互配合的定位结构。Embodiment 2: Refer to Figures 3 to 6 for details. A preferred technical solution in this embodiment differs from Embodiment 1 in that: the back of the anoscope 2 is provided with a positioning boss 3, which is aligned with the positioning boss 3. 3 Cooperate with the wide side 5 of the anal expander 1 and correspondingly open a plurality of mutually spaced positioning holes 4, and the positioning boss 3 snaps into the positioning holes 4 to form the mutual connection between the anoscope and the anal expander. Compatible positioning structure.
下面以肛肠科直肠前突手术为例来说明本器械的使用方式。首先，将本发明的器械配合内导管插入肛门后，退出内导管。然后插入肛镜。手术中只需稍微下压肛镜，通过肛镜背部的卡勾卡设于在扩肛器宽边的边缘上，即可实现肛镜与扩肛器的固定卡接；稍微下压肛镜的同时也可以将肛镜背后的定位凸台卡进扩肛器的定位孔内，实现两者的定位；然后用弯针将前突组织缝制荷包；扎完荷包后，再把圆管型外科装订器械放入手术区，把扎好荷包的粘膜组织从开口拉入到外科装订器械的腔内；然后用圆管型外科装订器械进行切割缝合，此时前突的粘膜组织被切掉，且伤口被闭合的很严密。手术中，需要转动肛镜时，稍微上抬肛镜，卡勾脱离扩肛器的宽边的边缘，同时定位凸台也脱离定位孔，便可以使得肛镜脱离扩肛器，然后方便地转动。The following uses anorectal rectocele surgery as an example to illustrate the use of this device. First, after inserting the instrument of the present invention into the anus with the inner catheter, the inner catheter is withdrawn. Then insert the anoscope. During the operation, you only need to press down the anoscope slightly, and the hook on the back of the anoscope is set on the edge of the wide side of the anal expander, so that the fixed connection between the anoscope and the anal expander can be realized; At the same time, the positioning boss on the back of the anoscope can also be snapped into the positioning hole of the anal expander to realize the positioning of the two; then use a curved needle to sew the protruding tissue into a purse; Put the stapling instrument into the operation area, pull the purse-bound mucosal tissue from the opening into the cavity of the surgical stapling instrument; then use the round tube surgical stapling instrument to cut and suture, at this time the protruding mucosal tissue is cut off, and The wound was tightly closed. During the operation, when the anoscope needs to be rotated, lift the anoscope up slightly, the hook will be separated from the wide edge of the anal expander, and the positioning boss will also be separated from the positioning hole, so that the anoscope can be separated from the anal expander, and then rotated conveniently .
此外，也可以在所述肛镜背部开设有定位孔，与所述定位孔配合在所述扩肛器上对应位置处设置多个定位凸台，定位凸台卡进定位孔内构成所述肛镜与所述扩肛器间的相互配合的定位结构。使用方式如下：只需稍微下压肛镜，肛镜背部的卡勾卡在扩肛器的宽边上，肛镜背部的定位孔套在定位凸台上，即可实现肛镜与扩肛器的定位固定；需要转动肛镜时，稍微上抬肛镜，卡勾脱离宽边，定位孔脱离定位凸台，肛镜即可与扩肛器脱离，方便地转动。In addition, a positioning hole can also be provided on the back of the anoscope, and a plurality of positioning bosses are arranged at corresponding positions on the anal expander in cooperation with the positioning holes, and the positioning bosses are snapped into the positioning holes to form the anus. A positioning structure that cooperates between the mirror and the anal dilator. The method of use is as follows: just press down the anoscope slightly, the hook on the back of the anoscope is stuck on the wide side of the anal expander, and the positioning hole on the back of the anoscope is set on the positioning boss, and the anoscope and the anal expander can be realized The positioning of the anoscope is fixed; when the anoscope needs to be rotated, the anoscope is lifted up slightly, the hook is separated from the wide side, the positioning hole is separated from the positioning boss, and the anoscope can be separated from the anal expander and rotated conveniently.
本发明尚有多种实施方式，凡采用等同变换或者等效变换而形成的所有技术方案，均落在本发明的保护范围之内。There are still many implementations in the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
