It should be noted that, for convenience of description, only the portions relevant to the present application are shown in the drawings. Embodiments of the present disclosure and features of embodiments may be combined with each other without conflict.

It should be noted that references to "one", "a plurality" and "a plurality" in this disclosure are intended to be illustrative rather than limiting, and those of ordinary skill in the art will appreciate that "one or more" is intended to be understood as "one or more" unless the context clearly indicates otherwise.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 to 3, the laparoscopic intra-abdominal marker 100 of the present application includes: handle 101, strut 102, pen container 103, nib 104; wherein a barrel 103 and a handle 101 are provided at both ends of a pole 102, respectively, a solution chamber 103a is constructed in the barrel 103, a nib 104 is inserted into an end of the barrel 103, and a nib 104 is partially inserted into the solution chamber 103 a.

Thus, when the abdominal cavity operation is performed, if the viscera in the abdominal cavity are required to be marked, the dye liquor can be filled into the solution cavity 103a of the pen container 103, and then the support rod 102 and the pen container 103 are placed into the abdominal cavity of the patient, so that the marks can be simply and conveniently made in the abdominal cavity of the patient, and the operation mode is equivalent to that of directly placing the marker pen into the abdominal cavity for operation, and has long operation time and simple operation mode; can improve the operation efficiency.

Referring to fig. 4, the pen container 103 is of a cylindrical structure, a plug cover 105 is arranged on the pen container 103, the plug cover 105 is in screwed connection with the pen container 103 and is used for sealing the solution cavity 103a, a piston 106 is connected to the plug cover 105 through an elastic piece 107, and the piston 106 can provide stable thrust for the dyeing liquid in the solution cavity 103a under the pushing of the elastic piece 107, so that uneven ink discharge is prevented. Thus, when the solution chamber 103a needs to be filled with the dye solution, and then the plug cover 105 is screwed on the pen container 103, the piston 106 needs to be attached to the plug cover 105 so as to compress the elastic piece 107; for this purpose, a fixing sleeve 1051 is rotatably disposed on the plug 105, a plurality of buckles 1052 are disposed on the inner wall of the fixing sleeve 1051, a fixing column 1061 is disposed on the piston 106, a plurality of protrusions 1062 are disposed on the edge of the fixing column 1061, and the protrusions 1062 are disposed obliquely; in this way, by compressing the elastic member 107, the plug 105 and the piston 106 are attached, that is, the connecting column is clamped into the fixing sleeve 1051, and then the protruding portion 1062 provided on the connecting column can be in interference fit with the buckle 1052 provided in the fixing sleeve 1051, the buckle 1052 can be a protruding portion provided at the end of the fixing sleeve 1051, and after the connecting column is inserted into the fixing sleeve 1051, the buckle 1052 will be abutted against the lower end of the protruding portion 1062. In this way, the piston 106 and the plug cover 105 can be connected at this time.

After the piston 106 is screwed on the pen container 103, the fixing sleeve 1051 and the connecting column can be separated from each other by rotating the fixing sleeve 1051; and the elastic member 107 can push the piston 106 and the liquid surface in the solution chamber 103a into contact with each other.

Further, the nib 104 is usually configured with a soft cotton structure to prevent scratch to the patient's organs, and the nib 104 is also full of liquid; for this reason, the nib 104 needs to be detachably coupled to the barrel 103 so that the nib 104 can be replaced every time an operation is performed to prevent infection of a patient.

Referring to fig. 3, a tapered connection portion 1031 is provided at an end portion of the barrel 103, the connection portion 1031 is a tapered portion provided at an end portion of the barrel 103, and the nib 104 is inserted into the connection portion 1031.

Further, the end of the connection portion 1031 is in a cylindrical structure, the pen tip 104 is inserted into the cylindrical structure, meanwhile, a chamfer portion 1032 is arranged at the end of the connection portion 1031, a notch 103b is arranged on the chamfer portion 1032, a fastening sleeve 109 is further screwed on the cylindrical structure of the connection portion 1031, and the inner wall portion of the fastening sleeve 109 is in a conical shape; for this reason, after the nib 104 is inserted into the connection portion 1031, the tightening sleeve 109 is rotated to retract the chamfer portion 1032, and then the chamfer portion 1032 presses the nib 104, thereby fixing the nib 104.

Further, a seal ring is provided in the connection portion, and the nib 104 abuts against the seal ring after being inserted into the connection portion.

When marking, the supporting rod 102 needs to be continuously rotated, so that different marks are drawn on the viscera; at some greater distances, and with too long a length of the mark being drawn, the amplitude of oscillation of the strut 102 may be excessive, and thus the strut 102 may adversely affect the wound on the abdominal cavity of the patient as it oscillates. For this reason, this application is through setting up pen container 103 and branch 102 to rotate the connection, and then through the mode of driving pen container 103 rotation, let under the condition of different swing branches 102, let pen container 103 rotate to make the mark on the viscera.

Referring to fig. 7, a rotation shaft 108 is provided on a supporting rod 102, a limiting plate 1021 is provided at the end of the supporting rod 102, two limiting plates 1021 are provided, a rotation space 102a for accommodating a pen container 103 is formed between the two limiting plates 1021, and the rotation shaft 108 is rotatably provided on the limiting plates 1021; the pen container 103 is connected with the rotating shaft 108; the end of the rotation shaft 108 is provided with a driven gear 111, a chain 112 is sleeved on the driven gear, a driving gear 113 is further arranged on the limiting plate 1021, the chain 112 is wound on the driven gear 111 and the driving gear 113, a pin 114 is arranged on the driving gear 113 in a penetrating mode, and therefore the driving gear 113 and the driven gear 111 are rotatably connected with the limiting plate 1021 in a closing mode. The pin 114 is provided with a fluted disc 1141, a rack 115 is arranged in the rotation space 102a, the rack 115 and the fluted disc 1141 are meshed with each other, the rack 115 is connected with a push rod 116, the push rod 116 is arranged on the support rod 102 in a penetrating way, and the push rod 116 penetrates the support rod 102 and is penetrated out of the handle 101. In this way, by moving the push rod 116, the rack 115 can be guided to drive the fluted disc 1141 to rotate, and then drive the driving gear 113 to rotate, and then drive the driven gear 111 to rotate, and further drive the pen container 103 to rotate.

Meanwhile, in actual work, many simpler marking works are directly drawn, so that when the push rod 116 is not pulled, the pen container 103 and the limiting plate 1021 are required to be prevented from rotating. For this purpose, the handle 101 is provided with a cavity 101a, a spring 117 is provided on the inner wall of the bottom end of the cavity 101a, and a ring piece 1161 is provided at the end of the push rod 116, and the ring piece 1161 is connected with the spring 117. The handle 101 is provided with an opening 101b, and the opening 101b and the cavity 101a communicate with each other. In this manner, by depressing the tab 1161, the push rod 116 may be guided for movement. The spring 117 gives a fixed force to the ring piece 1161, and guides the pen container 103 to be in a vertical state all the time. Further, a push plate 1011 is provided on the inner wall of the opening 101b, and the push plate 1011 and the handle 101 are slidably connected. When the pen container 103 is filled with the dye solution, the pen container 103 needs to be rotated to be perpendicular to the limiting plate 1021, so after the push rod 116 is pressed to be perpendicular to the pen container 103 and the limiting plate 1021, the push plate 1011 is slid above the push rod 116, and the push rod 116 is prevented from being reset, so that the dye solution in the pen container 103 can be filled.
