Description

Universal angle modulation scalpel

Technical field

This utility model relates to employed scalpel in a kind of medical appliance, particularly surgical operation, belongs to field of medical article technology.

Background technology

Scalpel is a surgery apparatus commonly used, and the general surgery cutter is made up of handle of a knife and blade, and the two has and fixed assembled is arranged also, though description is more, its basic structure all is staight shank, straight knife sheet, and promptly blade is substantially parallel with the axis of handle of a knife.This universal architecture can not satisfy the operation needs of different parts, and as some breast outer operation, the art open country is dark, otch is fixed, and scalpel is organized out of plumb with being cut when cutting off esophagus or trachea, can not once finish, and causes otch irregular.For this reason, Chinese patent 93212647 discloses the curved scalpel of a kind of esophagus trachea, and this scalpel can be selected different angles by to making blade and handle of a knife form 30 °, 45 °, 90 ° three kinds of angles after the architecture advances for use according to the operation needs.Above-mentioned improvement has solved the single problem of scalpel angle to a certain extent, but its adjustable extent is few, and adjusts fixed angle, so use still underaction.Technology such as plastic operation, operation on oral cavity, bone surgery get rapid development in the surgical operation in recent years, improved requirement to operating theater instruments is also corresponding, improve the structure of general surgery cutter, the motility and the adaptability that improve its use can play facilitation to improving the operation quality undoubtedly.

Summary of the invention

This utility model is used to solve the defective of above-mentioned prior art and the universal angle modulation scalpel that provides a kind of blade can arbitrarily adjust with respect to the handle of a knife angle, makes it to be used for cutting at any angle in the narrow lacuna.

The alleged problem of this utility model solves by the following technical programs:

A kind of universal angle modulation scalpel, be made of blade and handle of a knife, its special feature is: described handle of a knife 7 is hollow structure, establishes universal angle modulation assembly in the handle of a knife, described universal angle modulation assembly is made up of universal ball end 4, fixed bar 6 and blade bayonet socket 2, and fixed bar one side end presses universal ball end; Opposite side is connected with the handle of a knife internal diameter whorl, and described blade bayonet socket and universal ball end are affixed, and blade 1 is fixed by the blade bayonet socket.

Above-mentioned universal angle modulation scalpel, described universal ball end is provided with installing hole and screw hole along its centrage, and described blade bayonet socket shank 3 embeds in the installing holes and is fastening by screw 5.

Above-mentioned universal angle modulation scalpel, described handle of a knife 7 is cylindrical, the handle of a knife outer wall is provided with anti-skidding stricture of vagina 8.

Above-mentioned universal angle modulation scalpel is characterized in that: described fixed bar 6 one ends are provided with and screw anti-skidding annular knurl 9.

This utility model improves at general surgery cutter blade and handle of a knife fixed angle, awkward problem, universal angle modulation assembly is set in handle of a knife, blade is by being installed on the universal angle modulation assembly with the general blade bayonet socket of working standard, can adjust the angle of blade and handle of a knife during use according to operative site and doctor's operating habit easily, and angular dimension is unrestricted.This utility model can satisfy the operation needs of different parts, different depth, different levels by the replacing of different blades, is specially adapted to accurate surgical operation such as Oral and Maxillofacial Surgery, plastic surgery, department of cardiac surgery etc.In addition, this utility model also has, simple in structure, easy for installation, fastening firm, hold advantages such as comfortable.

Description of drawings

Fig. 1 is this utility model structural representation;

Fig. 2 is the A-A cutaway view of Fig. 1.

The label of each parts is expressed as follows in the accompanying drawing: 1. blade; 2. blade bayonet socket; 3. blade bayonet socket shank; 4. universal ball end; 5. screw; 6. fixed bar, 7. handle of a knife; 8. anti-skidding stricture of vagina; 9. screw anti-skidding annular knurl.

The specific embodiment

Referring to Fig. 1, this utility model is made of blade and handle of a knife, and blade is the used blade of common surgical procedures, handle of a knife is a hollow structure, establish universal angle modulation assembly in handle of a knife, universal angle modulation assembly is made up of universal ball end 4, fixed bar 6 and blade bayonet socket 3, and fixed bar one side end presses universal ball end; Opposite side is connected with the handle of a knife internal diameter whorl, and blade bayonet socket and universal ball end are affixed, and blade 1 is fixing by blade bayonet socket 2.Can select different blade bayonet sockets according to the difference of selected blade model, bayonet socket shank 3 is measure-alike.This structure can be adjusted blade angle in use as required, during adjustment, unclamps fixed bar and can arbitrarily rotate the universal ball end angle, and blade and handle of a knife angle promptly change thereupon, and the bar universal ball end that is tightened promptly is fixed together with blade.

Referring to Fig. 1, Fig. 2, universal ball end is provided with installing hole and screw hole along its centrage, and blade bayonet socket shank 3 embeds in the installing holes and be fastening by screw 5, and screw can adopt bulb one word or plus screw.For preventing blade rotation, blade bayonet socket shank and installing hole are square-section or flat cross section.Blade bayonet socket and working standard are general, and the blade of different size is installed on the universal angle modulation assembly by the blade bayonet socket.Can certainly adopt other connected mode commonly used that the blade bayonet socket is fixed in the universal ball end.
