Problems solved by technology

[0003] In the diagnosis and treatment of gastrointestinal surgery, it is often necessary to use the puncture operation for sampling and analysis, so as to make a more accurate diagnosis, and the general puncture auxiliary devices are purely fixed or equipped with a certain longitudinal displacement device, which cannot be used for special cases. The puncture is effectively assisted, and the assisted accuracy is not enough

Embodiment 1

[0038] Such as Figure 1-Figure 5 As shown, the locking mechanism 6 includes a fixing bolt 61, a first rotating block 62, a second rotating block 63, and a first inner positioning block 64. One end of the first rotating block 62 is provided with a second rotating block 63, and the first rotating block 62 The outside is connected with a fixing bolt 61, and a first inner positioning block 64 is arranged between the first rotating block 62 and the second rotating block 63, and the first inner positioning block 64 and the first rotating block 62 are integrally formed, and the first inner positioning block 64 and the second rotating block 63 are provided with a positioning elastic piece 65, when the position between the outer fixing mechanism 1 and the inner fixing mechanism 2 needs to be pre-adjusted, the first connecting rod 13 and the second connecting rod 14 can be pulled , and then the first inner positioning block 64 cooperates with the positioning elastic piece 65 to support...

Embodiment 2

[0040] The difference between this embodiment and embodiment 1 is:

[0041] Such as Image 6 , the locking mechanism 6 includes a fixing bolt 61, a first rotating block 62, a second rotating block 63, and a second inner positioning block 611. One end of the first rotating block 62 is provided with a second rotating block 63, and the first rotating block 62 is externally connected There are fixing bolts 61, a second inner positioning block 611 is arranged between the first rotating block 62 and the second rotating block 63, the second inner positioning block 611 and the first rotating block 62 are integrally formed, and the inner side of the second inner positioning block 611 is arranged There are eight positioning balls 612, a spring 613 is provided between the second inner positioning block 611 and the positioning ball 612, and a positioning groove 614 is provided between the positioning ball 612 and the second rotating block 63, when the external fixing mechanism 1 and the i...

Abstract

The invention discloses a gastrointestinal surgery abdominal cavity operation puncture device which comprises an external fixing mechanism used for supporting, an inner side fixing mechanism used for adjusting the angle, an angle adjusting mechanism and a suction mechanism used for driving a puncture needle to suck, and the inner side of the external fixing mechanism is connected with the inner side fixing mechanism. The inner side fixing mechanism is connected with the angle adjusting mechanism, the inner side of the angle adjusting mechanism is connected with the suction mechanism, the suction mechanism is connected with the puncture needle, the external fixing mechanism is provided with a locking mechanism, and the outer side of the inner side fixing mechanism is provided with a control button. The initial height and position of the device can be adjusted through cooperation of the external fixing mechanism and the inner side fixing mechanism, so that subsequent operation is facilitated, the puncture angle of the puncture needle can be adjusted and the puncture depth can be automatically controlled through cooperation of the angle adjusting mechanism and the suction mechanism, and therefore the puncture accuracy and operation convenience are guaranteed.

Description

technical field [0001] The invention relates to the field of gastrointestinal surgery, in particular to a puncture device for abdominal surgery in gastrointestinal surgery. Background technique [0002] Gastrointestinal generally refers to the stomach, small intestine, and large intestine of the digestive system. The stomach and small intestine are the core of nutrient absorption. Almost all the nutrients needed by the human body need to pass through the stomach. The stomach is the most important organ for digestion. The abdominal cavity is the cavity between the entrance to the pelvis and the diaphragm. Functionally, the abdomen is where most of the digestive tract is located, meaning that digestion and absorption all take place here. The digestive tract in the abdominal cavity includes the lower esophagus, stomach, duodenum, jejunum, ileum, cecum, and appendix, ascending colon, transverse colon, and descending colon, sigmoid colon, and rectum. Other vital organs are t...
