Problems solved by technology

However, in use, after completing one or even several operations, the structure and performance of the ultrasonic knife are still intact, but it is impossible to thoroughly clean and disinfect the inside of the knife body
Therefore, the ultrasonic scalpel produced in the early stage 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 medical ethics risk: In order to seek economic benefits, the used ultrasonic scalpel is used privately. It is inevitable that the risk of cross-infection will increase if the knife is not thoroughly cleaned and disinfected before being used on the next patient.
[0005] In order to reduce the risk of cross-infection, the invention patent with the application number CN201410023651.2 proposes an ultrasonic scalpel blade with a replaceable head, but the connection between the outer rod of the blade head and the outer rod of the blade is limited by balls When disassembling, use the thumb and forefinger to pull the knife rod sliding sleeve back, and rotate the knife head counterclockwise to the limit, and pull the spring sliding sleeve with the right hand, so that the knife head can be separated from the ultrasonic knife bar. The installation is complicated when connecting , the connection is unreliable

Embodiment 1

[0020] Such as figure 1 As shown, the present invention provides an ultrasonic scalpel with a replaceable cutter head, the connection structure between the cutter head rod group and the cutter rod group includes a mounting box 5, a driving device 1, a cylindrical cam 3, a connecting rod 2. Arc gear plate 4, double-sided rack 6, nut sleeve 9 and spring sleeve 8.

[0021] Wherein, the installation box 5 is fixed on the handle portion of the ultrasonic scalpel near the end of the knife head by means of threaded connection or slotted connection.

[0022] Wherein, the inner bottom surface of the installation box 5 is fixedly connected with a stepping motor, and the stepping motor is electrically connected with the power supply and the control switch arranged in the hand-held part through a control switch, and the output shaft of the stepping motor is connected with the cylindrical cam 3 through a shaft coupling. One end of the rotating shaft is connected, and the other end of the ...

Embodiment 2

[0029] As a further optimization scheme based on Embodiment 1, a detection device for the clamping force of the spring sleeve is added in this embodiment, so as to reduce potential safety hazards caused by too tight or too loose clamping force and improve connection reliability.

[0030] Specifically, a force measuring device is embedded on the surface of the spring sleeve 8 in contact with the outer rod of the cutter head, and the force measuring device is electrically connected to the controller, and the controller is electrically connected to the power supply and the control switch arranged on the hand-held part respectively. .

[0031] In use, you only need to press the control switch to start the stepping motor, and the stepping motor can drive the cylindrical cam 3 to rotate synchronously, and the slider in the spiral chute on the cylindrical cam 3 moves along the spiral chute to drive The connecting rod 2 moves synchronously. In order to adapt to the movement of the con...

Abstract

The invention relates to an ultrasonic scalpel with a replaceable scalpel head, and belongs to the technical field of medical operation apparatuses and instruments. The ultrasonic scalpel solves the problems of complex installation and unreliable connection, a connection structure between a scalpel head rod set of the ultrasonic scalpel and a scalpel rod set of the ultrasonic scalpel comprises aninstallation box, a driving device is fixed to the inner bottom surface of the installation box, and an output shaft of the driving device is connected with a rotary shaft of a cylindrical cam; the other end of the rotary shaft of the cylindrical cam is connected with a support, the support is fixed to the inner bottom surface of the installation box, and a first slide block is clamped in a spiralslide groove in the cylindrical cam; the first slide block can slide in the spiral slide groove, a connection rod is hinged to the first slide block, the end, away from the slide block, of the connection rod is hinged to an arc toothed disc, and the arc toothed disc is meshed with teeth of one surface of a two-sided rack; teeth of the surface, away from the arc toothed disc, of the two-sided rackare meshed with a nut sleeve, the nut sleeve is internally provided with a spring sleeve coaxially sleeved with the nut sleeve, the spring sleeve is fixed to the end, away from a handhold part of theultrasonic scalpel, of a scalpel rod outer pipe, and the nut sleeve is in threaded connection with the scalpel rod outer pipe. The ultrasonic scalpel is simple to operate and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of medical surgical instruments, and in particular relates to an ultrasonic scalpel with a replaceable cutter head. Background technique [0002] Ultrasonic scalpels are mostly used in minimally invasive surgery. Ultrasonic scalpels are a new technology surgical instrument that uses ultrasonic energy to treat soft tissues. It can complete cutting and coagulation at the same time, and can ensure minimal tissue lateral heat. damage. [0003] The popularity of ultrasonic scalpels has brought good news to patients. The structure of ultrasonic scalpels probably includes three parts: ultrasonic transducers, gun handles, and knife rod components. Among them, the ultrasonic transducer converts the electrical energy delivered by the host into ultrasonic resonance energy with a frequency of 55.5 kHz, and the ultrasonic transducer is inserted into the tail end of the gun-type handle and connected to the cutter body in...
