Embodiment 1

[0036] see Figure 1-8, A gastric cancer surgical instrument according to an embodiment of the present invention includes a gastroscope, a laparoscope, an intestinal forceps 1 and a resection device 2, the gastroscope includes a control panel 3, and a gastroscope lighting lamp 4, a gastroscope and a gastroscope are respectively installed on the control panel 3. An indicator 5 and a gastroscope camera 6, the control panel 3 is provided with an irradiation range changing mechanism matched with the gastroscope lighting lamp 4, and the intestinal forceps 1 includes a forceps whose intestinal forceps frame 7 is connected to the intestinal forceps frame 7. Leaves 8, the number of the forceps leaves 8 is two, the intestinal forceps frame 7 is provided with an opening width positioning mechanism for the opening and closing of the two forceps leaves 8, and the number of the gastroscope lighting lamps 4 is several One, the irradiation range changing mechanism is a telescopic cover 9 tha...

Embodiment 2

[0042] see figure 1 , the position of the gastroscope camera 6 is close to the position of the gastroscope indicator 5, the gastroscope lighting lamp 4 and the gastroscope camera 6 are arranged around the gastroscope indicator 5, and the gastroscope indicator 5 is provided with a point light source, so The point light source includes a red light-emitting diode light source and a strong ultraviolet light source.

[0043] Through the above solution of the present invention, the beneficial effects are as follows: the position of the gastroscope indicator is close to the position of the gastroscope camera, thereby reducing the deviation between the position indicated by the bright spot of the gastroscope indicator and the position of the tumor seen in the field of view of the gastroscope camera, and improving the prompting of gastric tumors. accuracy of location;

[0044] The point light source can be generated by a red light-emitting diode, or it can be a strong ultraviolet ligh...

Embodiment 3

[0046] see Figure 5 , a marking pen 28 is installed on the pliers blade 8, the marking pen 28 is detachably arranged on the pliers blade 8, and the pliers blade 8 is provided with a mounting groove 29 for installing the marking pen 28, so A slot 30 is opened at the end of the inner wall of the installation slot 29 , the end of the marker pen 28 is inserted into the slot 30 , and a pressing plate 31 is fixed on the marker pen 28 , and the inner wall of the slot 30 is A secondary pressing plate 32 with a spring is fixed, the marker 28 is provided with a marker nib 33, the material of the marker nib 33 is cotton material, and the marker nib 33 uses methylene blue solution as a dye. liquid,

[0047] Through the above-mentioned solution of the present invention, the beneficial effects are as follows: the marker pen 28 is used to set the marker pen on the intestinal forceps, and the marker pen can be used to mark the resection line on the gastrointestinal wall during the operation...

Abstract

The gastric cancer surgical instrument comprises a gastroscope, a laparoscope, intestinal forceps and a resection device, the gastroscope comprises a control panel, a gastroscope illuminating lamp, a gastroscope indicator and a gastroscope camera are installed on the control panel, and an irradiation range changing mechanism matched with the gastroscope illuminating lamp is arranged on the control panel. The intestinal forceps comprise an intestinal forceps frame and two forceps blades connected to the intestinal forceps frame. The tumor excision forceps have the advantages that the manual screw rotates to drive the U-shaped frame to move, so that the two inclined plates are driven to be opened and closed, the forceps blades are driven to be opened and closed, the forceps blades are automatically fixed after being opened and closed, the function of opening width positioning is completed, the operation time is long during tumor excision, a large amount of blood or even fester exudes from diseased tissue, and the operation difficulty is lowered. In the prior art, a soft catheter, a connecting tube and a drainage device are adopted for drainage and suction, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the medical field, in particular, to a gastric cancer surgical instrument. Background technique [0002] Gastric cancer is a common malignant tumor in China. The popularity of gastroscope has enabled more and more gastric cancers to be detected at an early stage. If surgical resection can be performed early, the survival rate of patients can be greatly improved. Since the tumor grows from the inside of the stomach and the early tumor size is small, there may only be a tiny ulcer surface on the mucosal surface of the stomach, and there is no trace of lesions on the outermost serosal surface of the stomach. Therefore, the location of the tumor cannot be determined only under the laparoscopic view. Moreover, during laparoscopic surgery, doctors cannot feel the location of the lesions in the stomach by touching their hands, which makes it difficult to accurately remove the lesions under laparoscopic surgery. The image is roughly ...
