Description

Direct View Minimally Invasive Straight Scissors

technical field

The utility model relates to a pair of scissors, in particular to a direct-view minimally invasive straight scissor, which is suitable for minimally invasive human body surgery, especially for separating internal organs of the human body, and belongs to the field of medical equipment.

Background technique

In traditional surgical operations, an incision is usually made on the patient's skin and flesh, the short is 6-10 cm, and the length is 10-15 cm or longer. During the operation, once a lesion is found in the human body, it needs to be resected. During the resection operation, the organs in the body need to be separated to find the lesion. The existing technology is to perform pneumoperitoneum in the human body to make the operation have a certain space. Use surgical forceps to find the lesion site. Its defect is: one uses pneumoperitoneum operation, and operation time is long, and patient's difficult wound healing is slow, if patient's body is weak wound healing effect is just worse;

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned problems existing in the prior art, and provide a kind of straight-view minimally invasive straight scissors with reasonable structure design and small trauma.

The technical solution adopted by the utility model to solve its technical problems is: the direct-view minimally invasive straight scissors include a fixed handle, a movable handle, a movable knife, a fixed knife, a bearing sleeve, a bearing seat, a pull rod and a pincer rod, and is characterized in that: A return spring, a support block, a pull rod groove, a pull rod seat, a block, a rotator, a flusher and a rotator are provided, the return spring is installed between the fixed handle and the movable handle, and the support block is integrated with the fixed handle. The pull rod groove is opened on the movable handle; one end of the pull rod is connected with the movable knife, and the other end is fixed with the pull rod seat; superior.

There are two back-moving springs described in the utility model, which are pressed against each other, and are respectively fixed on the described fixed handle and the movable handle with fixed pins.

Compared with the prior art, the utility model has the beneficial effects that: the structure design is reasonable, only 2-3 centimeters of incision is needed, and the incision is stretched by using a special pull hook, and the light beam of the cold light source is concentrated into the human body through the guide beam, which can make the The surgeon can clearly see all parts of the body directly, and the risk of infection is reduced due to the small incision; the effect is good, and the operation is convenient and safe.
