Abstract

The utility model provides an ultrasonic knife jaw, wherein a rotating hole is formed in the tail of the jaw and is connected with an outer tube of a knife body of an ultrasonic knife through the rotating hole; the upper surface of the jaw is provided with a plurality of strip-shaped heat dissipation holes; the lower surface of the jaw is provided with a T-shaped sliding groove for installing a wear-resistant pad. The jaw of the ultrasonic knife is provided with the plurality of strip-shaped heat dissipation holes, so that the heat dissipation of the ultrasonic knife is facilitated, the temperature rise of the ultrasonic knife is small, and the ultrasonic knife is stable and stable in operation. Because the T-shaped sliding groove is formed in the lower surface of the jaw of the ultrasonic knife, the wear-resistant gasket can be firmly and stably installed, and the wear-resistant gasket is not easy to fall off. On the T type spout of installation wear-resisting gasket, open along the groove body direction has a plurality of bar flares, is favorable to wear-resisting gasket's installation for can be lighter just install wear-resisting gasket level and smooth and firm.

Description

Ultrasonic knife jaw

Technical Field

The utility model relates to the technical field of medical instrument manufacturing, in particular to an ultrasonic knife jaw.

Background

With the increasing demand for medical technology, the development of medical equipment is promoted in the direction of smaller surgical wounds and less bleeding. Ultrasonic knife surgery is currently in widespread clinical use.

The jaw portion of the existing ultrasonic knife head is poor in heat dissipation effect, the burning area is large when the ultrasonic knife cuts tissues easily, the work is unstable, the temperature rise in the work is large, the temperature is not well controlled, meanwhile, the jaw portion of the existing ultrasonic knife head is not well matched with a wear-resistant gasket of the ultrasonic knife head, and the wear-resistant gasket is prone to falling off.

The ultrasonic knife jaw which has a good heat dissipation effect, is not easy to fall off from a wear-resistant gasket and is convenient to enter a narrow space to clamp a detached object needs to be developed in the market.

SUMMERY OF THE UTILITY MODEL

The utility model provides an ultrasonic knife jaw which can enable an ultrasonic knife to work stably, vibrate stably and control temperature.

In order to achieve the purpose, the utility model provides the following technical scheme: a jaw of an ultrasonic knife is provided with a rotating hole at the tail part, and is connected with an outer tube of a knife body of the ultrasonic knife through the rotating hole; the upper surface of the cog jaw is provided with a plurality of strip-shaped heat dissipation holes; the lower surface of the jaw is provided with a T-shaped sliding groove for installing a wear-resistant pad.

Preferably, the head part of the jaw is provided with an inclined surface. The head of the cutter head cog jaw of the ultrasonic knife is provided with the inclined plane, so that the ultrasonic knife can conveniently enter a narrow space to clamp tissues of a human body or an animal.

Preferably, the strip-shaped heat dissipation holes are through holes, and part of the strip-shaped heat dissipation holes are communicated with the T-shaped sliding groove. The strip-shaped heat dissipation holes are through holes, and heat dissipation is facilitated.

Preferably, the T-shaped chute is alternately provided with strip-shaped flares along the direction of the chute body. The alternately arranged strip-shaped flaring openings are beneficial to installing the wear-resistant pad in the T-shaped sliding groove. And then guarantee that the abrasion pad does not drop, be favorable to the centre gripping tissue that the supersound sword can be better, strengthen the blood coagulation effect.

Compared with the prior art, the utility model has the beneficial effects that:

1. because the jaw of the ultrasonic knife is provided with the plurality of strip-shaped heat dissipation holes, the heat dissipation of the ultrasonic knife is facilitated, the temperature rise of the ultrasonic knife is small, and the ultrasonic knife works stably and stably.

2. Because the T-shaped sliding groove is formed in the lower surface (inner surface) of the jaw of the ultrasonic knife, the wear-resistant gasket can be firmly and stably installed, and the wear-resistant gasket is not easy to fall off.

3. According to the T-shaped sliding chute for installing the wear-resistant gasket, the plurality of strip-shaped flaring openings are formed along the direction of the chute body, so that the wear-resistant gasket can be installed easily, smoothly and firmly.

Detailed Description

An embodiment of an ultrasonic blade jaw of the present invention is further described with reference to fig. 1 to 4.

A jaw of an ultrasonic knife is characterized in that a rotating hole 1 is formed in the tail of the jaw, and the jaw is connected with an outer tube (not shown in the figure) of a knife body of the ultrasonic knife through the rotating hole 1; the head part of the cog jaw is provided with an inclined plane 2. The upper surface of the jaw is provided with a plurality of strip-shaped heat dissipation holes 3; the lower surface of the jaw is provided with a T-shaped sliding groove 4 for installing a wear-resistant pad. The strip-shaped heat dissipation holes 3 are through holes, and part of the strip-shaped heat dissipation holes 3 are communicated with the T-shaped sliding groove 4. The strip-shaped heat dissipation holes 3 are through holes, and heat dissipation is facilitated. The T-shaped chute 4 is alternately provided with strip-shaped flaring holes 41 along the direction of the chute body.

The cutter head of the ultrasonic knife is generally divided into two sections, one section is a working section for applying ultrasonic waves, and the other section is a jaw with a toothed wear-resistant pad. The jaw flap and the working flap of the forceps are matched together to form a cutter head of the ultrasonic knife, and the ultrasonic knife can cut, clamp and stop bleeding of human or animal tissues when working.

The jaw of the ultrasonic knife is provided with the plurality of strip-shaped heat dissipation holes, so that the heat dissipation of the ultrasonic knife is facilitated, the temperature rise of the ultrasonic knife is small, and the ultrasonic knife is stable and stable in operation. Meanwhile, the head part of the jaw of the cutter head of the ultrasonic cutter is provided with the inclined surface, so that the ultrasonic cutter can conveniently enter a narrow space to clamp tissues of a human body or an animal. The alternately arranged strip-shaped flaring openings are beneficial to installing the wear-resistant pad in the T-shaped sliding groove. And then guarantee that the abrasion pad does not drop, be favorable to the centre gripping tissue that the supersound sword can be better, strengthen the blood coagulation effect.
