Problems solved by technology

When the scalpel device works at a fixed non-node position, it will increase heat and energy loss, which not only reduces the efficiency of the operation, but also causes damage to human tissue cells due to the conduction of overheating

Embodiment 1

[0032] Such as Figure 1 to Figure 8 As shown, an ultrasonic scalpel includes a blade head 1, a handle 2, and a vibration device 4 enclosed in a housing 3.

[0033] The scalpel head 1 is made of titanium alloy and has a long columnar structure. The tool handle 2 is made of engineering plastics, and the tip 1 and the front end of the tool handle 2, and the vibration device 4 and the end of the tool handle 2 are all connected by bolts. According to the cutting type surgical device, the length of the cutter head 1 is a slender metal tube with a length of 10-30 cm. When the working frequency of 30KHZ is selected, the amplitude of the cutter head 1 can reach 40um, so that the cavitation effect occurs during cutting, which is more conducive to cutting biological tissues.

[0034] The vibration device 4 is composed of a Langzhiwan transducer and an horn, which converts electrical energy into ultrasonic energy, and the cutter head 1 applies the ultrasonic energy to the lesion.

[0035] Th...

Embodiment 2

[0044] Reference Picture 10 The difference between this embodiment and Embodiment 1 is only that the shape of the groove 4 at the AA section is different from that of Embodiment 1. The notch extends inward from the outer surface of the housing 3, which can provide a better deformation effect.

[0045] The present invention uses the cavitation effect to complete the cutting process. Since the ultrasonic cavitation is completed in water-rich cells, it has a better effect on tissues with a lot of water content. During the operation, it does not rely on heat loss, and there is no overheating phenomenon, so it will not form smoke or affect the healing of the incision tissue. The cutting speed of the ultrasonic scalpel is fast, and the temperature rise of the blade head has obvious hemostatic effect.

[0046] By improving the traditional ultrasonic scalpel, the present invention realizes the non-contact support of the ultrasonic scalpel, and solves the problems of low work efficiency, l...

Abstract

The invention discloses an ultrasonic scalpel, which comprises a cutter head (1), a knife handle (2) connected with the cutter head (1), and a vibration device packaged in a shell (3) and connected with the knife handle (2) (4), a thin film (7) is arranged between the housing (3) and the vibrating device (4); the housing (3) encapsulating the vibrating device (4) is axially provided with several sets of axial vibrating pieces ( 5); the casing (3) encapsulates the vibrating device (4) and the handle (2) is provided with several groups of radial vibrating pieces (6) along the radial direction. There are also several grooves (8) on the place where the casing (3) encapsulates the vibrating device (4). The invention realizes the non-contact support of the ultrasonic scalpel through the improvement of the traditional ultrasonic scalpel, and solves the problems of low working efficiency, large heat generation and difficult heat dissipation.

Description

Technical field [0001] The invention relates to the technical field of ultrasonic scalpels, and more specifically to a non-contact supporting ultrasonic scalpel. Background technique [0002] When the traditional scalpel cuts human cell tissue, its cutting effect is poor. The main manifestation is that it requires multiple cuts to achieve the cutting effect, and the amount of bleeding during the cutting process is large and it is not conducive to wound healing. Therefore, in recent years, the medical field has paid more and more attention to the application research of ultrasonic scalpel. It has achieved the advantages of separation, incision and hemostasis. It does not require frequent replacement of surgical instruments during the operation, which shortens the operation time and reduces the risk. . At present, ultrasonic scalpels are mainly used in bone cutting, cataract emulsification, and open thyroid surgery. [0003] However, the vibration device in the traditional ultrason...
