Problems solved by technology

[0003] Since the thickness of the digestive tract is usually different (that is, the inner diameter is usually different), before using the tubular stapler in the operation, it is necessary to evaluate the thickness of the digestive tract in order to select different types of tubular staplers (that is, to choose different outer diameters). tubular stapler); however, in the prior art, during the operation, doctors usually only rely on naked eye observation (visual inspection) and experience to assess the thickness of the digestive tract and select the tubular stapler model, which is prone to tubular stapler model selection Improper operation can lead to complications such as anastomotic stenosis or anastomotic leakage; in addition, because the tubular stapler is an expensive disposable consumable, when the model is too large to be placed in the digestive tract, a new tubular must be replaced Stapler will not only cause waste of medical resources, but also greatly increase the economic burden of patients

Embodiment 1

[0059] Such as figure 1 , figure 2 as well as image 3 As shown, the present embodiment provides an inner diameter measuring device for assisting the selection of a tubular stapler, including a base 101, a spring 102, a fixed measuring head 103, and a movable measuring head 104. The base 101 is provided with a sliding track 113, the fixed measuring head 103 is fixed on the base 101, and is located at one end of the sliding track 113, the length direction of the fixed measuring head 103 is perpendicular to the length direction of the sliding track 113;

[0060] One end of the movable measuring head 104 is connected on the slide block 105, and the slide block 105 is adapted to the sliding track 113, so that the sliding block 105 can be arranged in the sliding track 113 and can move along the sliding track 113, and the movable measuring head 104 is connected with the fixed measuring track 113. The heads 103 are parallel to each other, because the slider 105 can move along the ...

Embodiment 2

[0077] The main difference between this embodiment 2 and the above-mentioned embodiment 1 is that, in this embodiment, both the movable measuring head 104 and the fixed measuring head 103 adopt a cylindrical structure, such as Figure 10 As shown; in the actual measurement process, the movable measuring head 104 and the fixed measuring head 103 are respectively in contact with the measured object through the side walls of the cylindrical structure, since the side walls of the movable measuring head 104 and the fixed measuring head 103 are arcs The surface 112 has no edges and corners, not only will not cause damage to the object 301 to be measured (such as the esophagus, intestinal tract, etc. in the digestive tract), but also can make the object 301 to be measured and the arc surface 112 fit better and more closely , thereby improving the measurement accuracy.

[0078] Utilizing the inner diameter measuring device provided in this embodiment for assisting in the selection of ...

Embodiment 3

[0080] It can be seen from the above-mentioned embodiments that in the actual measurement process or calibration process, what actually plays a role and effect is the circular arc surface 112 on the outside of the fixed measuring head 103 and the movable measuring head 104, while the fixed measuring head 103 and the movable measuring head 104 The structure of the upper position and the inner side is not limited, as long as it does not exceed the height of the arc surface 112, it is all feasible solutions, and all belong to the protection scope of the present invention;

[0081] For example, in this embodiment, the cross-sections of the fixed measuring head 103 and the movable measuring head 104 are all arcuate, such as Figure 12 As shown, at this time, both the fixed measuring head 103 and the movable measuring head 104 are part of a cylinder. Using this inner diameter measuring device, in the actual measurement process, when the movable measuring head 104 and the fixed measur...

Abstract

The invention relates to an inner diameter measuring device used for type selection of an auxiliary pipe type anastomat. The inner diameter measuring device comprises a base, a spring, a fixed measuring head and a movable measuring head, wherein a sliding track is arranged on the base, and the fixed measuring head is fixed on the base and located at one end of the sliding track; one end of the movable measuring head is connected with a sliding block, the sliding block is matched with the sliding track, the movable measuring head and the fixed measuring head are parallel to each other, and themovable measuring head can move along the sliding track; the spring is arranged in the sliding track between the sliding block and the fixed measuring head; the outer surface, far away from the movable measuring head, of the fixed measuring head and the outer surface, far away from the fixed measuring head, of the movable measuring head are arc surfaces respectively, a pointer is arranged on the movable measuring head or sliding block, and the pointer is used for indicating inner diameter value of a measured object. The inner diameter measuring device provided by the invention is compact in structure and easy to operate and can provide accurate size reference for type selection of the pipe type anastomat, so that defects in the prior art are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an inner diameter measuring device for assisting type selection of tubular staplers. Background technique [0002] At present, the tubular stapler is a common medical device used in digestive tract reconstruction in gastrointestinal surgery, thoracic surgery and other surgical operations; One end of the canal is docked with the central rod of the stapler passing through the digestive canal to be anastomosed at the other end, and a complete cut and anastomosis is performed. This method can effectively shorten the operation time, improve the quality of surgery, and provide support for minimally invasive surgery of gastric cancer, rectal cancer, esophageal cancer and other tumors, and has been widely used in clinical practice. [0003] Since the thickness of the digestive tract is usually different (that is, the inner diameter is usually different), before using the tubul...
