Document Type and Number:
WIPO Patent Application WO/2024/066963
Kind Code:
A1
Abstract:
Provided is a connecting and sealing structure used for an ultrasonic knife driving handle, wherein a multi-section driving handle housing (10) comprises a front driving handle housing (101), a middle driving handle housing (102), and a rear driving handle housing (103) which are successively in communication with each other. An ultrasonic wave generating member (20) is mounted in the front driving handle housing (101) and the middle driving handle housing (102). A water injection member (30) is mounted in the rear driving handle housing (103) and protrudes from the rear driving handle housing. The connecting and sealing structure comprises a first connecting structure (11) arranged between the front driving handle housing (101) and the middle driving handle housing (102), a second connecting structure (21) arranged between the middle driving handle housing (102) and the rear driving handle housing (103), a third connecting structure (31) arranged between the water injection member (30) and the rear driving handle housing (103), and a fourth connecting structure (41) arranged at a communication part between the water injection member (30) and the ultrasonic wave generating member (20). By means of the connecting and sealing structure, the connecting and sealing performance of the ultrasonic knife driving handle is optimized, such that the production efficiency can be effectively improved, and the production and maintenance costs are reduced.
