Inner diameter measuring device for tubular anastomat

Abstract

The invention discloses an inner diameter measuring device for a tubular anastomat, and belongs to the technical field of medical instruments. The device comprises a base, a screw rod is arranged in the base, a sliding seat is arranged on the surface of the screw rod, a movable measuring head is connected to one end of the sliding seat, and a fixed measuring head is arranged on the side edge of the base. The adjusting bolt rotates to drive the screw rod to rotate, the sliding seat on the surface of the screw rod moves, the movable measuring head on the side edge of the sliding seat slides along the sliding rail to enable the fixed measuring head and the movable measuring head to be tightly attached to the inner wall of a pipe, the base is taken down to observe the position of the pointer on the dial gauge, then the inner diameter value is measured, and inaccurate measurement caused by back movement of the movable measuring head due to finger looseness is avoided; and by adjusting the sliding seat to move, a connecting contact piece is driven to move on the surface of a sliding resistor, the resistance value of the sliding resistor is changed, a corresponding inner diameter value isdisplayed on the display screen according to the change of the resistance value, meanwhile, a loudspeaker carries out voice broadcasting on the value, and inner diameter measurement is facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to an inner diameter measuring device for a tubular stapler. Background technique [0002] The stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. It is generally divided into one-time or multiple-use staplers, imported or domestic staplers. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable, especially its fast suturing, easy operation and There are few side effects and surgical complications, and it also enables tumor resection that was unresectable in the past.

AI Technical Summary

Problems solved by technology

[0003] The existing internal diameter measuring devices for tubular staplers have the following problems during use: 1. The measurement needs to be fixed by pressing the limit position all the time, and when the measurement is released, the movable measuring head moves back, causing measurement trouble;

[0004] 2. It is troublesome to read data by aligning the pointer with the scale, and it is impossible to perform voice broadcast and numerical display, which causes trouble in use;

[0005] 3. The tube at one end cannot be fixed during measurement, and it is easy to cause the tube to fall when operated by a single person, causing trouble in measurement
