Description

Ultrasonic cutting hemostatic knife

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an ultrasonic cutting hemostatic knife.

Background

Ultrasonic cutting hemostatic knives are commonly used in open surgical procedures to cut a target tissue within a patient and to stop bleeding from the target tissue after cutting. For the convenience of operation, the existing ultrasonic cutting hemostatic scalpel is often in a scissor-like shape, and as shown in fig. 1 and fig. 2 in particular, the ultrasonic cutting hemostatic scalpel includes two half structures connected together in a hinged manner, wherein one half of the two half structures includes a transducer 100, a knife bar 200 and a treatment head 300 connected in sequence, the transducer 100 can generate ultrasonic energy, so as to drive the treatment head 300 located at the front end of the knife bar 200 to generate mechanical vibration of ultrasonic frequency, so as to complete cutting of soft tissue. And the other half of the two half structures comprises a fixedly connected handle 400 and a jaw 500, the middle part of the handle 400 is hinged with the middle part of the knife bar 200, the jaw 500 is positioned at the front end of the handle 400 and is arranged opposite to the treatment head 300, and the rear part of the clamping handle 400 can drive the jaw 500 to rotate towards the treatment head 300 while the transducer 100 excites the treatment head 300 to generate mechanical vibration, so that the jaw 500 and the treatment head 300 are closed to grasp the target tissue to realize cutting hemostasis.

Since the weight of the half structure of transducer 100, tool bar 200, and treatment head 300 is much greater than the mass of the half structure of handle 400 and jaws 500, the half structure of transducer 100, tool bar 200, and treatment head 300 is typically configured as a static portion, i.e., the half structure is placed in the hand of the operator during use, for comfort and flexibility of operation during use. And the other half structure comprising the handle 400 and the jaw 500 is set as a movable part, the handle 400 is positioned above the knife bar 200, the jaw 500 is positioned below the treatment head 300, and the rear end of the handle 400 is buckled by a thumb to rotate so as to realize the rotation of the movable part relative to the static part, so that the treatment head 300 and the jaw 500 are closed.

In actual use, for separating thin fascia structures and other soft tissues, the operator will often flip the targeted tissue with the vibrating treatment tip 300 after the transducer 100 has been energized with ultrasonic energy to effect separation and cutting, and only close the jaws 500 to effect a grasping cut when encountering a thicker or difficult-to-cut targeted tissue. In the scissors type ultrasonic cutting hemostatic knife, only the activated knife bar 200 and the treatment head 300 can really realize the cutting function, and the jaw 500 is only used as a matching part and provides clamping and holding together with the treatment head 300 after being closed, so that the hemostasis after cutting is more efficient.

Because the two halves of traditional scissors are equal in weight and the two halves of scissors are provided with cutting edges, the scissors can have a good shearing effect no matter whether rotating any half or rotating the two halves simultaneously when shearing. The scissors type ultrasonic cutting hemostatic knife has the advantages that through the design of reference scissors, although the structure is simple and clear, the following defects still exist in the practical use process:

because the weight difference of the two half parts of the scissors type ultrasonic cutting hemostatic knife is very large, and the treatment head 300 for performing the cutting operation is positioned above the jaw 500, the problems of inconvenient operation, low operation efficiency, poor hemostatic effect caused by the fact that the treatment head 300 cannot be closed with the jaw 500 in time after being picked can be caused when the treatment head 300 is used for picking the target tissue. Moreover, since the treatment head 300 is located above the jaws 500 and the target tissue in actual operation, the operator may be easily blocked from view, which may cause malfunction. In addition, the positioning of the treatment head 300 for performing the cutting operation above the target tissue is not in accordance with the familiar operation habit of positioning the member having the cutting function below the member to be cut, and the operability and the use experience of the operator are poor.
