Description
Technical Field
The utility model belongs to the technical field of medical instrument, especially, relate to a bipolar haemostat of percutaneous nephroscope.
Background
Percutaneous nephrolithotomy refers to a minimally invasive surgical technique in which a nephroscope is placed in the calyx of the renal pelvis through a channel from the skin to the kidney, and the upper urinary tract stones are broken up and removed by means of laser, ultrasound and other lithotripsy tools. The percutaneous nephroscope operation has the defects that a small number of patients have large bleeding of puncture channels, and the traditional hemostasis modes comprise two modes, namely compression hemostasis and electric coagulation hemostasis; the compression hemostasis has low use cost and convenient operation, but has limited hemostasis effect; although the electric coagulation hemostasis has good hemostasis effect, the electric coagulation hemostasis is affected by blood or liquid accumulation, and the operation is not convenient enough.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defect that the electric coagulation hemostat is easily influenced by accumulated liquid in the prior art, and provide a percutaneous nephroscope bipolar hemostat with good hemostasis effect and convenient operation.
In order to realize the purpose, the percutaneous nephroscope bipolar hemostat designed by the utility model comprises a drainage tube, an electric coagulation head, an electrode interface and a negative pressure connecting tube; the front end of the drainage tube is an open end, and the rear end of the drainage tube is a closed end; the two electrocoagulation heads are respectively arranged at one side close to the opening end of the drainage tube at intervals, and each electrocoagulation head is connected with an electrode interface arranged at the closed end of the drainage tube through a conducting wire arranged in the drainage tube; a plurality of drainage holes are also formed in one side of the drainage tube close to the opening end of the drainage tube; the closed end of the drainage tube is provided with a nephroscope inserting hole and a negative pressure connecting hole; one end of the negative pressure connecting pipe is connected with the negative pressure connecting hole, and the other end of the negative pressure connecting pipe is connected with a negative pressure source.
Furthermore, one side of the drainage tube, which is opposite to the drainage hole, is also provided with an observation window.
Further, a sealing ring is arranged in the nephroscope stretching hole.
Furthermore, the outer wall of the drainage tube is provided with at least one plane and one arc surface.
The utility model has the advantages that: through the cooperation of drainage tube and electricity congeals the head, not only stanch effectually, but also suction hydrops, the hemostasis operation is more convenient swift, improves hemostasis efficiency.
Drawings
Fig. 1 is a schematic perspective view of the percutaneous nephroscope bipolar hemostat of the present invention.
Fig. 2 is a rear view structural diagram of fig. 1.
In the figure, a drainage tube 1, an electrocoagulation head 2, an electrode interface 3, a negative pressure connecting tube 4, an opening end 5, a closed end 6, a lead 7, a drainage hole 8, a nephroscope extension hole 9, a negative pressure connecting hole 10, a sealing ring 11 and an observation window 12.
Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
A percutaneous nephroscope bipolar hemostat shown in fig. 1 and 2, which comprises a drainage tube 1, an electrocoagulation head 2, an electrode interface 3 and a negative pressure connecting tube 4; the front end of the drainage tube 1 is an open end 5, and the rear end is a closed end 6; the number of the electrocoagulation heads 2 is two, the electrocoagulation heads are respectively arranged at one side close to the opening end 5 of the drainage tube 1 at intervals, and each electrocoagulation head 2 is connected with an electrode interface 3 arranged at the closed end 6 of the drainage tube 1 through a lead 7 arranged in the drainage tube 1; the two electrode interfaces 3 are respectively connected with the bipolar output end of the existing high-frequency surgical instrument.
One side of the drainage tube 1 close to the opening end 5 is also provided with a plurality of drainage holes 8; the closed end 6 of the drainage tube 1 is provided with a nephroscope inserting hole 9 and a negative pressure connecting hole 10; one end of the negative pressure connecting pipe 4 is connected with the negative pressure connecting hole 10, the other end of the negative pressure connecting pipe 4 is connected with a negative pressure source, the negative pressure source is the existing equipment, a negative pressure switch is arranged on the negative pressure source, and the negative pressure switch is started to form negative pressure in the drainage pipe 1 and suck effusion in the puncture channel.
The nephroscope inserting hole 9 is also provided with a sealing ring 11, and the percutaneous nephroscope enters the drainage tube 1 through the nephroscope inserting hole 9 and can extend out from the opening end 5 of the drainage tube 1. An observation window 12 is arranged on one side of the drainage tube 1 opposite to the drainage hole 8. The outer wall of the drainage tube 1 is provided with at least one plane and one arc surface. Because the intersection of the plane and the arc surface has an edge, a fluid channel exists between the puncture channel and the drainage tube 1, and accumulated liquid can be sucked out more quickly.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that a person skilled in the art should also recognize that several modifications and decorations can be made without departing from the principle of the present invention, and the protection scope of the present invention is also covered.
