Abstract
The utility model discloses an ultrasonic scalpel handle, which relates to medical instruments and comprises a handle body in the shape of curved head scissors. The handle body is composed of a scalpel head, scalpel arms and finger rings, the scalpel head includes a fixed head and a moving head, an ultrasonic guide tube is disposed in a front section of one scalpel arm connected with the moving head, the rear section of the scalpel arm is an open-ended tubular part for insertion of an ultrasonic transducer, the moving head is connected with the front end of the ultrasonic guide tube and actuated by ultrasonic, the scalpel is 3-8cm in length, preferentially 7cm in length, a switch is arranged inside the tubular part and is opened and closed by a user closing or opening the two scalpel arms. The ultrasonic scalpel handle is flexible in operation, combines clotting, cutting and tissue isolating operations together, frequent change of tissue isolating instruments in a surgery is not needed, and thereby operating efficiency is improved greatly and surgical time is reduced. Further, finger pushed type an operating button of the handle is changed into touch type, and thereby the handle is convenient for surgical operation and is convenient and practical.
Description
Technical field
This utility model relates to a kind of ultrasound knife handle, belongs to technical field of medical instruments.
Background technology
Ultrasound knife is to begin to be applied to operating a kind of new medical apparatus the latter stage eighties abroad, very fast in the development of developed countries such as the U.S., Japan at present, various head and neck surgical operations have been widely used in, the trend that replaces electric knife is arranged greatly, and its safety and superiority have obtained the confirmation of numerous clinical trials.Ultrasound knife utilizes the supersonic frequency generator that the metal cutter head is vibrated with supersonic frequency, makes water vapor in the tissue, the albumen hydrogen bond rupture, and cell disruption, tissue is cut open or solidifies.The cutting accuracy height, blood coagulation may command, little smog and eschar, no current is by body, and ultrasound knife has improved the operating safety of head and neck, has reduced operating difficulty, reduce operating time, and head and neck surgery Wicresoft level is further improved, range of operation is more extensive.As seen the using ultrasound cutter carries out the head and neck surgical operation and can make easy and simple to handlely, improves operative speed, and amount of bleeding is few, and wound is little, recovers fast.
But still there is following problem in using ultrasound cutter handle at present: 1. because switch is arranged at the outer surface of handle arm, make that the handle volume is big, operate dumb; 2. too short because of the cutter head of handle, big multiple-length is 2～3cm, can only be applied to clamp hemostasis (coagulating, cut function) and can not be used for separate tissue, has dwindled the scope of application.In addition, prolonged operating time owing to need frequently to change separation instrument in the art; 3. the switch of handle (control is cut with fixed attention) uses inconvenient by forefinger or middle finger control.
The utility model content
The technical problems to be solved in the utility model is: a kind of ultrasound knife handle is provided, and its flexible operation will coagulate, cut, the separate tissue operation combine together, improve operation efficient, and the action button of handle becomes touch from finger by the control formula, makes things convenient for operation technique.
To achieve these goals, the technical solution adopted in the utility model is: a kind of ultrasound knife handle comprises being the scissors-like handle body of elbow that it is made up of cutter head, tool arm, finger ring; Described cutter head is divided into stationary knife head and dynamic cutter head; The preceding intrasegmental part of the tool arm that links to each other with dynamic cutter head is equipped with ultrasonic waveguide, back segment be open ended be used to peg graft the tubular body of ultrasonic transducer; Dynamic cutter head is connected with the ultrasonic waveguide front end and by ultrasonic actuating, described cutter head is grown 3～8cm; Described tubular body outer surface inboard is provided with switch, and it starts, closes by closed two tool arms of user.
Further, described switch is two grades of press buttones, is used to control first level and second level of ultrasonic transducer.
As preferably, described stationary knife head medial surface engages shaggy clamp pad.
Further, described clamp pad surface is broached-tooth design.
Further, described clamp pad front portion is provided with and the dynamic cutter head corresponding groove along stationary knife head length degree direction.
As preferably, the long 7cm of described cutter head.
The beneficial effect that this utility model brings is: (1) switch is arranged at the inboard of tool arm, makes the tool arm volume reduce flexible operation; (2) cutter head adds and grows to 3～8cm, and the good separating effect of organ-tissue will coagulate, cuts, lock out operation combines together, need not in the art frequently to change the separate tissue apparatus, and is easy to use, reduced operating time; (3) action button of handle becomes touch from finger by the control formula, made things convenient for operation technique, select two grades of formula press buttones for use, when two tool arms are drawn close closure, click first level of switch activated ultrasonic transducer, double-click second level of switch activated ultrasonic transducer, press button rebounds during by the 3rd time, is in closed condition.This ultrasound knife can control efficiently and easily condense, cutting operation, can carry out separate tissue again when switch cuts out, with separate tissue with to coagulate, cut operation not only independent but also combining of continuity arranged, convenient and safe, improved operation efficient greatly in the operation.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of ultrasound knife handle, it removably connects by ultrasonic transducer and ultrasonic generator, comprise and be the scissors-like handle body of elbow, be made up of cutter head, tool arm, finger ring, tool arm, finger ring are made by durable plastic material, also can be made by pottery or metal.Cutter head can adopt rustless steel or other can have the acoustics compatible material of effect spread ultrasonic energy to make, and is preferably titanium alloy.Cutter head can adopt titanium alloy.Described cutter head is divided into dynamic cutter head 11 and stationary knife head 12, and dynamic cutter head 11, stationary knife head 12 are connected with first tool arm 21 respectively and second tool arm, 22, the first finger rings 31, second finger ring 32 link to each other with first tool arm 21, second tool arm 22 respectively; The inside of first tool arm, 21 leading portions is equipped with ultrasonic waveguide, back segment be open ended be used to peg graft the tubular body 23 of ultrasonic transducer; Dynamic cutter head 11 is connected with the ultrasonic waveguide front end and by ultrasonic actuating, the long 3～8cm of described cutter head be preferably 7cm, and cutter head bends to arcuation; Described tubular body 23 outer surface inboards are provided with switch 4, and it starts, closes by closed two tool arms of user.
