Abstract

The invention relates to an auxiliary light source of an ultrasonic scalpel, belonging to surgical operating instruments. In ordinary surgical operations, the ultrasonic scalpel is generally used for carrying out operations such as tissue separation, and the like, but when abdominopelvic cavity deep part operations or perineum operations are carried out, operative field lighting is difficult, which causes operation difficulties and risks. Aiming to solve the problem, the invention ensures that the auxiliary light source can be conveniently fixed on the rod of the ultrasonic scalpel and turned on through a design of a clamping groove of a small electric torch, a light gathering cover and a switch capable of being fixed and moves along with the ultrasonic scalpel to lighten a scalpel head operation area so as to provide good operative field lighting in deep part operations.

Description

Auxiliary light source of ultrasonic scalpel

Technical field

The present invention relates to surgical operating instrument, is the secondary light source that aims at ultrasound knife design, the wild illumination of art when being used for ultrasound knife and carrying out the deep operation.

Background technology

At present, ultrasound knife has been widely used in operation.In abdominal surgery, the normal deep operation of using ultrasound knife to carry out abdominal cavity, pelvic cavity or meeting private parts, as operating in the pelvic cavity in the radical resection of rectal carcinoma, excise the operation of anus etc. in carcinoma of the rectum Mile ' the s art, this moment is dark and narrow and small owing to the operating position, the wild difficult exposure of art, the shadowless lamp light of operating table top is difficult to the ideal illumination is carried out in the art open country, cause the art open country dim, operating difficulties causes the damage of blood vessel or other institutional frameworks easily.

Summary of the invention

Lighting problem when carrying out the deep operation with ultrasound knife for solution, the invention provides a kind of auxiliary light source of ultrasonic scalpel, can be installed on easily when needed on the ultrasound knife knife bar, open the back and directly illuminate the cutter head operating area with the motion of ultrasound knife, art open country limpid in sight is provided, reduces operation and accidentally injure probability.

Technical scheme of the present invention is: auxiliary light source of ultrasonic scalpel is a small-sized torch of polypropylene shell, torch is cylindrical, diameter 10mm, length 50mm, by four pieces of 1.5V button cell power supplies, adopt LED bulb energy-conservation, high brightness, by fixable foward-push switch open, polypropylene shell one side has the draw-in groove structure, the draw-in groove cross section is the annular of a side opening, its thickness 1mm, draw-in groove length 25mm, opening diameter 3.5mm, has the umbrella shape outer cover around the front end bulb, cover length 10mm, cover mouthful diameter 12mm, the auxiliary light source of ultrasonic scalpel specific embodiment is as follows:

1. the small-sized torch of polypropylene shell, by the foward-push switch open, switch has concaveconvex structure, is convenient to promote, preceding push away to connect can be fixed in this position after circuit is opened bulb.

2. the polypropylene shell of torch has the draw-in groove structure at the switch offside, and annular shape and ultrasound knife knife bar coincide in the draw-in groove, and its outer openings is slightly less than the knife bar diameter, can utilize polypropylene material elasticity to be fastened on easily on the knife bar, fixedly torch.

3. torch adopts LED bulb energy-conservation, high brightness, has the umbrella snoot around the bulb, can converge the border circular areas of light around the ultrasound knife cutter head, strengthens illuminating effect.

The specific embodiment

Auxiliary light source of ultrasonic scalpel is a small-sized torch of polypropylene shell, torch is cylindrical, diameter 10mm, length 50mm, by four pieces of 1.5V button cell power supplies,, adopt energy-conservation by fixable foward-push switch open (Fig. 1-2), the LED bulb of high brightness, polypropylene shell one side has the cross section annular, the draw-in groove structure of one side opening, draw-in groove thickness 1mm, length 25mm, opening diameter 3.5mm (Fig. 2-3), has the umbrella snoot around the bulb, cover length 10mm, cover mouthful diameter 12mm (Fig. 1,2,4) outward appearance as shown in Figure 5 after, secondary light source was fixed in the ultrasound knife knife bar.

Among the embodiment shown in Figure 6, auxiliary light source of ultrasonic scalpel is fixed in the ultrasound knife knife bar, opens the back and illuminates the cutter head operating area with the knife bar motion, appears art open country clearly in the operation of deep.

Claims

1. auxiliary light source of ultrasonic scalpel, for shell has draw-in groove design of mini torch, it is characterized in that: by draw-in groove, snoot with can switch fixedly design, make light source can be fixed on the ultrasound knife knife bar easily, illuminate the cutter head operating area with the ultrasound knife motion, the good wild illumination of art is provided in the operation of deep.

2. auxiliary light source of ultrasonic scalpel according to claim 1, it is characterized in that: small-sized torch polypropylene shell has the draw-in groove structure, the draw-in groove cross section is the annular of a side opening, annular shape and ultrasound knife knife bar coincide in it, opening diameter is slightly less than the knife bar diameter, utilize the elasticity of polypropylene material to be sticked in knife bar, fixed light source.
