Ultrasonic scalpel bar with replaceable scalpel head

Abstract

The invention discloses an ultrasonic scalpel bar with a replaceable scalpel head. The ultrasonic scalpel bar comprises a scalpel bar assembly and a scalpel head assembly. Under the state that the scalpel head is mounted, the tail end of a scalpel bar inner pipe (6-2) is in buckling connection with the front end of a scalpel head inner pipe (5-2), a scalpel bar outer pipe (5-1) is located between an outer pipe locating sleeve (6-4) and a scalpel rod inner pipe (6-2), and balls (6-10) are located in second ball locating through holes (6-4A-3) and clamped in first ball locating through holes (5-1A). When the scalpel head is dismounted, a spring sliding sleeve (6-9) compresses a spring (6-8) and moves, the balls (6-10) are located in a fourth step hole (6-9C), and the balls (6-10) can be loosened. The ultrasonic scalpel bar has the advantages of being reliable in mounting and easy to dismount, clean and disinfect, the scalpel bar with the scalpel head dismounted down can be used repeatedly, the operation consumable cost is greatly lowered, the burden of a patient is relieved, and the risk of possibly and repeatedly using the ultrasonic scalpel bar is lowered.

Description

technical field [0001] The invention relates to the technical field of minimally invasive medical instruments, in particular to an ultrasonic scalpel cutter bar with a replaceable cutter head. Background technique [0002] Ultrasonic scalpel uses ultrasonic energy to process soft tissue, cutting and coagulation are completed at the same time, and can ensure minimal lateral thermal damage to tissue. With the popularity of minimally invasive surgery, ultrasonic scalpel has become a routine surgical instrument. Take a certain series of ultrasonic scalpels with the highest market share as an example to illustrate its basic working principle, such as Figure 1A and Figure 1B As shown, the ultrasonic scalpel is mainly composed of three parts: the ultrasonic transducer handle 01, hereinafter referred to as the transducer 01; the gun handle 02, hereinafter referred to as the handle 02; The transducer 01 converts the electric energy delivered by the host into ultrasonic resonance ...

AI Technical Summary

Problems solved by technology

After completing one or even several operations, the structure and performance of the ultrasonic scalpel are still intact, but the inside of the blade cannot be thoroughly cleaned and disinfected

Therefore, the above-mentioned ultrasonic scalpel can only be used as a one-time surgical instrument according to the regulations, and should be discarded after the operation is completed, but its price is high, and there is also a huge potential risk of medical ethics: In order to seek economic benefits, the used ultrasonic scalpel is used in private. It is inevitable to increase the risk of cross-infection if it cannot be thoroughly cleaned and disinfected before being used on the next patient.
