Abstract
The utility model discloses a medical hydraulic giant operating scalpel which comprises a hydraulic giant body, the valve seat of a nozzle, a nozzle, a piston head, a piston rod, a spring, a control rod, a waterproof cover, etc. The utility model is used to match with a high-pressure hydraulic pump when used in operation. A tissue organ can be cut by the impulse force of high-pressure physiological saline, and hepatic tissue can be selectively cut. An intrahepatic duct, an artery and a vein are not damaged, the amount of bleeding is reduced when in operation, the safety of the operation is enhanced, and the resection rate is increased. The utility model has the advantages of convenient operation and easy mastery. The putrescence of the tissue organ is stopped when in operation, and the danger of hematorrhea caused by damaging aorta is especially avoided. The utility model is fit for a big-sized, a middle-sized and a small-sized medical units.
Description
This utility model relates to a kind of scalpel that surgical diseases is used for the treatment of.
The present general surgery cutter of usefulness, cutting skin and flesh tissue soon, but easy damaged blood vessel and cause massive hemorrhage.Electric knife, laser scalpel, plasma blade, microwave coagulation treatment all has electric injury, hot injury in various degree when making surgical operation, it is more downright bad that muscular tissue is produced, and cause the wound healing delay and cause secondary infection, even the damage trunk causes the danger of massive hemorrhage.Also there is complicated operation in above-mentioned several scalpel, is difficult to grasp the use main points, expensive deficiency.
The purpose of this utility model provides a kind of medical hydraulic giant scalpel, it utilizes the impulse force of water under high pressure, can optionally cut hepatic tissue, does not damage stones in intrahepatic bile duct, tremulous pulse, vein during operation, reduce the amount of bleeding in the operation, the safety that has improved operation has widely increased the resection rate of operation.
Below in conjunction with accompanying drawing this utility model scalpel is carried out detailed narration.
Fig. 1 is the generalized section of the medical hydraulic giant scalpel of this utility model.
Fig. 2 is the generalized section of nozzle valve seat (2) among Fig. 1.
Fig. 3 is the sketch map of nozzle among Fig. 1 (16).
Fig. 4 is the sketch map of the bending shape of nozzle among Fig. 3 (16).
Fig. 5 is the OBL sketch map of bucker among Fig. 1 (14).
As shown in Figure 1, the medical hydraulic giant scalpel of this utility model is by playpipe (1), nozzle valve seat (2), piston rod (4), spring (5) piston head (6), control stick (7), interior nut (9), exterior nut cap (10), adjusting nut (11), bucker (14), nozzle formations such as (16).The body of a gun (1) shape such as fountain pen, the left end of the body of a gun (1) is provided with the Baltimore groove that is connected with nozzle valve seat (2), be provided with water cavity (13) and plunger shaft (15) in the body of a gun, one side of the body of a gun is provided with the water inlet pipe (12) that communicates with plunger shaft (15), be provided with support column (8) with the symmetric side of water inlet pipe (12) on the body of a gun, the right-hand member of the body of a gun is provided with the screw that connects exterior nut cap (10).Nozzle valve seat (2) shape such as taper stage body, as shown in Figure 2, its right-hand member is provided with the convex step that connects with the body of a gun (1) Baltimore groove, is provided with nozzle chambers (3) in the nozzle valve seat (2).Piston rod (4), spring (5), piston head (6) all are placed in the plunger shaft (15), and piston head (6) is connected with piston rod (4), and spring (5) is enclosed within on the piston rod (4).Displacement by the energy regulating piston bar of the adjusting nut (11) on the piston rod (4) (4).Bucker (14) shape such as desk lamp cover shape are arranged on the connection place of the body of a gun (1) and nozzle valve seat (2).Needs bucker according to cutting muscular tissue can be made into as shown in Figure 5 oblong-shaped, during use the rectangle bucker is placed on the human body that is cut the nozzle valve seat (2) with hydraulic giant to place water cover hole (17), to prevent the rebound effect of water again.Support column (8) hinge connection on control stick (7) and the body of a gun (1) is fixedlyed connected with piston rod (4), and the past bottom offset by control stick (7) can make piston rod (4) lateral displacement.Nozzle (16) shape such as injection needle insert in the nozzle chambers (3) of nozzle valve seat (2), and it can make straight shape or elbow shape is shown in figure (3), (4).
This utility model is to use like this, the hydraulic giant scalpel is matched in high-pressure hydraulic pump, water inlet pipe (12) is connected with the high pressure saline tube, and normal saline enters plunger shaft (15) by water inlet pipe (12), and enters water cavity (13) by piston head and penetrated by nozzle (16).Hold control stick (7) during operation, when control stick (7) down on time, by control stick (7) apply piston bar (4), piston head (6) is promptly toward moving right, the high pressure normal saline passes through.When loosing one's grip, piston rod (4) resets under the effect of spring (5), and piston head (6) cuts off current.Fragile situation according to histoorgan regulates different hydraulic pressure, also can utilize temporarily and regulate the fine setting that nut (11) is made discharge and pressure.Can select the nozzle straight shape or bending (16) of different-diameter simultaneously for use according to the different parts of operation.
The utility model medical hydraulic gun operating scalpel is for excising the tissues such as liver cell and brain, pancreas, kidney Organ, and can remain with flexible artery, vein, bile duct and ductus pancreaticus etc. Compare with existing scalpel and to have infringements such as hepatic tissues fewly, oozing of blood is few in the operation, and few intercurrent disease has particularly improved the security of operation widely, has increased Resection Rate, and easy to operate, is easy to use the advantage of popularization. And prove that through clinical use its curative effect of curer of doing lobectomy of liver etc. through this scalpel obviously is better than other type of surgery cutter.
