Description

Liposuction device for laparoscopic breast surgery

technical field

The invention relates to the field of endoscopic surgery equipment, in particular to a liposuction device for endoscopic breast surgery.

Background technique

When breast diseases require surgical treatment, conventional breast surgery requires an incision on the surface of the breast, which requires a long enough incision to expose the surgical field so that the operation can be completed under direct vision; the unavoidable huge incision is a surgical technical problem that has yet to be resolved . Breast loss and certain surgical complications from surgery can affect a woman's physical appearance and cause psychological harm. Laparoscopic surgery is a minimally invasive surgical method developed from laparoscopic surgery, and it is an inevitable trend in the development of future surgical methods. The basic principle of laparoscopic surgery is to form a cavity inside the viscera and photograph the viscera on the monitor screen. Under the monitoring and guidance of the high-tech monitor, the surgeon manipulates the surgical instruments externally to detect and electrocoagulate the diseased tissue. , hemostasis, tissue separation and incision, suture and other operations. It is a model of the application of high-tech technologies such as electronics, optics, and photography in clinical operations. It has the characteristics of less trauma, fewer complications, safety, and quick recovery.

Laparoscopic breast surgery usually includes fat melting process, liposuction process, laparoscopic operation process, specimen removal process, flushing detection process, drainage and bandaging process. The liposuction operation was started at intervals of 10 minutes after the fat-dissolving solution was injected. During the liposuction process, an incision of about 0.5 cm in diameter was made at the trocar entry site marked before the operation, and then a suction head with a side hole was inserted, and full liposuction was performed on the planned operation field with a negative pressure of 0.2-0.8 kPa. During subcutaneous liposuction, care should be taken to avoid suctioning the cephalic hole directly toward the skin; for liposuction in the posterior space of the breast, the cephalic hole should be directed toward the gland, and for axillary liposuction, the cephalic hole should be directed away from the axillary vein to avoid violent operations. The existing liposuction tube has a simple structure and needs to be operated to maintain the orientation of the side hole, otherwise it will cause unnecessary harm to the patient. The existing liposuction device does not have the side hole deflection protection function, which increases the difficulty of the operation , Second, it increases the risk of surgery.

Contents of the invention

The invention provides a liposuction device for laparoscopic breast surgery, which solves the problem that the liposuction device in the prior art does not have the function of protecting side hole deflection.

A liposuction device for endoscopic breast surgery, comprising a negative pressure generating device, a negative pressure tube is connected to the negative pressure generating device, a liposuction needle is connected to the negative pressure tube, a handle is fixedly connected to the liposuction needle, and a handle is provided on the handle. An angle detection device is provided, and the signal on the angle detection device is connected with a control device, and the control device is connected with the signal of the negative pressure generating device. When the present invention is used, through the preset control device, when the handle rotates, the liposuction needle will be rotated and the angle detection device will be triggered. After the signal received by the control device exceeds the preset value, the negative pressure generating device will be controlled to cut off the power, and the liposuction The negative pressure in the needle disappears, which avoids the damage to the patient caused by turning the liposuction needle by mistake during laparoscopic breast surgery, and reduces the difficulty and risk of the operation.

Further, the angle detection device includes an angle sensor, the input shaft of the angle sensor is provided with a counterweight, and the axis of the input shaft is parallel to the axis of the liposuction needle. Reasonably set the mass of the counterweight and the distance from the center of the counterweight to the axis of the input shaft to ensure that the torque of the counterweight under the action of gravity is greater than the starting torque of the angle sensor. For example, the starting torque of the angle sensor model WDS22A-1 is less than 0.098N·m, then the gravitational moment of the counterweight should be greater than this value. In this way, when the handle is rotated, the counterweight can drive the input shaft of the angle sensor to rotate, so that the angle sensor detects the angle signal of the rotation.

Further, the handle is provided with a cavity, the angle sensor is located in the cavity, and the cavity is provided with a detachable cover plate. The cover prevents accidental contact with the input shaft of the angle sensor.

Further, the angle detection device includes a rotating shaft fixed on the handle and distance sensors located on both sides of the rotating shaft, a counterweight trigger is connected to the rotating shaft through a bearing, and the distance sensor is arranged on the handle. When the handle is rotated, the two distance sensors move accordingly, and the counterweight trigger is always located directly below the rotating shaft, and the counterweight trigger will approach and trigger one of the distance sensors, causing the negative pressure generating device to stop.

Further, the angle detection device further includes a casing, and the rotating shaft, the counterweight trigger, and the distance sensor are located in the casing. The housing prevents accidental contact with the weight trigger.

Further, the liposuction needle is tubular, one end is open and the other end is closed, the open end communicates with the negative pressure tube, and a through hole is provided on the side wall of the liposuction needle close to the closed end. The side wall opening can keep the opening from facing the skin all the time and causing damage.

Further, the handle includes a first handle part and a second handle part, the first handle part and the second handle part are detachably connected, and there is a channel for the liposuction needle to pass between the first handle part and the second handle part , the angle detection device is arranged on the second handle part, and the liposuction needle is connected with the first handle part through a spline or a flat key. The first handle part and the second handle part are detachably connected, the liposuction needle can be easily replaced, and it is suitable for a disposable liposuction needle.

Further, a bracket is also included, the liposuction tube is provided with an accommodating cavity, and the accommodating cavity is fixed on the bracket. The accommodating cavity is used for accommodating the fat sucked out by the liposuction needle, and the bracket can fix the accommodating cavity to prevent its excessive weight from interfering with the operation.

As can be seen from the above technical solutions, the present invention has the following advantages:

When the handle rotates, the liposuction needle rotates and triggers the angle detection device. When the signal received by the control device exceeds the preset value, the negative pressure generating device is controlled to be powered off, which avoids accidental rotation of the liposuction needle during endoscopic breast surgery. It causes damage to the patient and reduces the difficulty and risk of the operation.
