Embodiment 1

[0028] This embodiment provides a laser penetrating intestinal wall positioner, including a laser penetrating intestinal wall positioner mirror body and a display control system, the laser penetrating bowel wall localizer mirror body includes a handle 2, a probe rod 6, and the handle 2 Connected with the probe rod 6, one end of the probe rod 6 is provided with a support point, and the other end is provided with a support ring, the handle 2 and the probe rod 6 are both hollow structures, and the handle 2 or the probe rod 6 are provided with multiple A laser, the front part of the probe rod 6 is provided with a laser light outlet 8 and a camera 9, a prism is installed in the laser light outlet 8 in the probe rod 6, an illumination light source 10 is embedded in the front part of the probe rod 6, and a wire 1 One end is connected to the display control system, and the other end of the wire 1 passes through the handle 2 and the probe rod 6 to be electrically connected to the laser,...

Embodiment 2

[0043] On the basis of Embodiment 1, this embodiment provides a laser penetrating intestinal wall positioner, the laser device is arranged in the handle 2 , and an optical fiber is arranged between the laser device and the laser light outlet 8 .

[0044] Due to the limited size of the probe rod 6, the number of lasers installed inside will be limited. Therefore, the lasers are installed on the handle 2 and transmitted through the optical fiber.

[0045] In this embodiment, there are multiple laser light outlets 8, which are evenly distributed in the circumferential direction on the outer surface of the probe rod 6. Multiple turns. When the laser light outlets 8 are linear and multi-turn, the laser light outlets 8 of adjacent circles are arranged in a staggered manner. The illumination light source 10 is an LED light source, and there are 1-2 LED light sources.

[0046] Wherein, the display control system includes a microcomputer and a display, both of which are electrically c...

Embodiment 3

[0049]On the basis of Embodiment 1, this embodiment provides a laser penetrating intestinal wall locator, and the outer surface of the probe rod 6 is provided with a scale 7 . The outer surface of the probe rod 6 is provided with a laser light source switch 3 and an illumination light source switch 4 , and the laser light source switch 3 and the illumination light source switch 4 are electrically connected to the wire 1 . The scale 7 can make the doctor judge the insertion depth.

[0050] Such as figure 1 As shown, the front end of the lens body of the laser penetrating intestinal wall locator is a probe rod 6, and the rear end is a handle 2. The side of the head of the probe rod 6 is sequentially equipped with an illumination light source 10, a camera 9, and a laser light outlet 8. The laser light outlet 8 is dot-shaped, distributed in a ring shape on the outer surface of the probe rod 6, the laser light outlet 8 is a single row, the distance between the center of the laser...

Abstract

The invention provides a laser intestine wall penetrating positioner and a low rectal tumor positioning method. The laser intestine wall penetrating positioner comprises a laser intestine wall penetrating positioner lens and a display control system, a supporting point is arranged at one end of a detection rod, a supporting ring is arranged at the other end of the detection rod, a plurality of lasers are arranged in a handle or the detection rod, the front of the detection rod is provided with a laser outlet and a camera, a prism is arranged at the laser outlet, an illumination lighting sourceis embedded into the front of the detection rod, a one end of a lead is connected with a display control system, the other end of the lead is connected with the lasers, the illumination lighting source and the camera, the distance between the laser outlet and the camera is 10-20mm, and the camera approaches to the front end surface of the detection rod as compared with the laser outlet. Accordingto the laser intestine wall penetrating positioner, a tumor is more rapidly searched in a visual environment, the laser outlet is circularly formed, observation of any angle outside an intestinal canal is achieved by a laparoscope, positioning points are appeared in a visual field, the distance between the camera and the laser outlet is known, cross markings on a display are matched, positioningaccuracy can be accurate to + / -2mm, and accurate anus preservation is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a laser penetrating intestinal wall locator and a method for locating low-position rectal tumors. Background technique [0002] The low rectal tumor is very close to the patient's anus, and the incision location is between the tumor and the anus. If the incision is too close to the tumor, it may be incompletely removed, and if the incision is too far away, it may damage the anal tissue and affect the function of the sphincter. Therefore, precise anus preservation is to preserve the complete anal tissue as much as possible under the premise of complete tumor resection, which is very important to ensure the quality of life of patients after surgery. [0003] For routine laparoscopic resection of low rectal tumors, a doctor needs to probe into the patient's anus with his fingers, touch the tumor (the tumor grows on the inner side of the intestine), and use his fi...
