Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to an automatic reciprocating swelling fluid injection and liposuction device. Background Art

[0002] With the improvement of living standards and the maturity of cosmetic surgery technology, liposuction for body shaping and fat transplantation have become the hot spot and focus in the field of medical cosmetology. The most widely used tumescent and negative pressure liposuction surgeries are divided into two steps: first, a tumescent fluid containing local anesthetics and adrenaline is injected into the adipose tissue with a water injection needle to facilitate the extraction of fat. Secondly, the adipose tissue is sucked out under the action of negative pressure using a liposuction needle. At present, when water is injected during tumescent negative pressure liposuction, the tumescent fluid is provided by a hand-push syringe or a roller pump. Then the handle equipped with the water injection needle is manually held to make reciprocating motions to inject the tumescent fluid into the adipose tissue. When tumescent negative pressure liposuction is performed to suck fat, the handle equipped with the liposuction needle is manually held to make reciprocating motions to suck out the fat under the action of negative pressure. There are also proposals to use cylinders to achieve reciprocating motions, but this solution has not been transformed into a physical object for application in clinical surgery.

[0003] The existing technology has the following deficiencies: the existing reciprocating injection of tumescent fluid and liposuction and injection of tumescent fluid devices are manually realized to achieve reciprocating motion, which not only increases the labor intensity of doctors, but also causes uneven injection of tumescent fluid. If a cylinder is used to achieve reciprocating motion, not only a separate air source must be prepared, but improper operation is also dangerous. In addition, the cylinder has a high decibel noise, is easily damaged, and has a short service life, thereby increasing the cost investment.

[0004] Therefore, it is necessary to invent a kind of automatic reciprocating injection swelling fluid and liposuction device. Summary of the invention

[0010] The liposuction and swelling fluid injection device also includes a liposuction needle, the liposuction needle is inserted into the inner wall of the semicircular extrusion plate, the outer wall of the right end of the liposuction needle is connected to the Z-shaped tube, the inner wall of the right end of the bottom of the Z-shaped hole is threadedly connected to the metal piston tube, the input end of the metal piston tube is inserted into the inner wall of the second metal tube, the input end of the metal piston tube is fixedly installed on the inner wall of the small piston, and the small piston is inserted into the inner wall of the second metal tube.

[0011] Preferably, the input end of the feed one-way valve is plugged into the inner wall of the water injection pipe.

[0012] Preferably, the electromagnetic generator is plugged into the inner wall of the shell.

[0013] Preferably, the magnetic rod is inserted into the inner wall of the electromagnetic generator.

[0014] Preferably, the left end of the shell is connected to the shell cover.

[0015] Preferably, positioning plates are fixedly mounted on both ends of the outer wall of the shell.

[0016] Preferably, the inner wall of the positioning plate at the left end is plugged into the second metal tube.

[0017] Preferably, the inner wall of the positioning plate at the right end is plugged into the metal tube 1.

[0018] The beneficial effects of the present invention are:

[0019] When the present invention is used and swelling fluid needs to be injected, the water inlet needle is first placed in the semicircular squeezing plate, and then the semicircular squeezing plate is threadedly connected to the Z-shaped tube to squeeze and fix the water inlet needle, and then the output ends of the rubber tube and the feed tube are respectively connected to the metal tube 1 and the Z-shaped tube, and then the input end of the feed tube is connected to the metal tube 2, and only the Y interface and the X interface are connected through the metal tee joint, so that the Y interface and the X interface are not connected to the Z interface, so that the metal tube 1 and the metal tube 2 are connected. Then start the electromagnetic generator, the electromagnetic generator will drive the magnetic rod to move to the left, the magnetic rod moving to the left will drive the large piston to move, when the large piston moves to the left, the swelling fluid in the water injection pipe will be sucked into the movable column through the feed one-way valve, after entering, the large piston will be moved to the right, and then the large piston will squeeze the swelling fluid in the movable column, the squeezed swelling fluid will enter the rubber tube through the discharge one-way valve, and enter the Z-shaped hole through the metal tube 1 and the metal tube 2, and then the Z-shaped hole will let the swelling fluid flow into the water inlet needle;

[0020] When liposuction is required, first place the liposuction needle in the semicircular squeezing plate, then thread the semicircular squeezing plate and the Z-shaped tube to squeeze and fix the liposuction needle, then separate the metal tube 1 from the rubber tube, and then separate the feed tube from the metal tube 2 and the Z-shaped tube, and then connect the two ends of the metal piston tube to the Z-shaped hole and the inner wall of the metal tube 2 respectively, so as to avoid the magnetic rod from rotating itself, thereby ensuring that the direction of the side hole of the liposuction needle does not change arbitrarily. If it is necessary to use an external negative pressure device to provide negative pressure for liposuction, only the Y interface and the X interface are connected through the metal three-way joint, so that the Y interface and the X interface are not connected to the Z interface, so that the metal tube 1 and the metal tube 2 are connected, and then the metal tube 1 is connected to the external negative pressure device, and then the external negative pressure device is started, and the external negative pressure device will extract the air in the Z-shaped hole through the metal tube 1, the metal tube 2 and the metal piston tube, and the negative pressure is combined with the electric The magnetic generator drives the magnetic rod to move left and right, so that the liposuction needle extracts fat through the Z-shaped hole. If the Y interface, X interface and Z interface are connected through the metal three-way joint, negative pressure will not be generated at the front end of the liposuction needle, and the fat cannot be extracted by only the forward and backward movement of the liposuction needle. Therefore, when the three interfaces of the metal three-way joint are connected to each other, the Z interface can be blocked or opened by the fingertips to control the presence or absence of negative pressure in the liposuction needle, thereby achieving the purpose of arbitrarily controlling whether the fat is sucked out. If liposuction is required to rely on the negative pressure generated by the pumping of the syringe, the external syringe is connected to the Z interface, and then only the Z interface and the X interface are connected through the metal three-way joint, which will prevent the Z interface and the X interface from being connected to the Y interface, thereby achieving the connection between the external syringe and the metal tube 2, and then the external syringe is pulled to generate negative pressure, and the electromagnetic generator is used to drive the magnetic rod to move left and right, so as to extract fat through the liposuction needle. The electromagnetic generator drives the magnetic rod to perform reciprocating motion, which has the effects of reducing the doctor's labor intensity, shortening the operation time, reducing the cost of liposuction surgery and making the injection of swelling fluid more uniform.
