Problems solved by technology

Whether it is a suction-type ultrasonic scalpel or a cutting-type ultrasonic scalpel, these existing ultrasonic scalpels are all connected by straight tubes or long straight tubes and a very short section of cone knife. However, the connections of these straight tubes In practical application, if the structural method is located at the diameter-changing part of the straight pipe, such as using a horn structure, etc., the reflection of the ultrasonic frequency electrical signal will be blocked due to the rapid change of the aperture, resulting in high energy consumption for sound wave transmission and slow wave-guided velocity. Affect the effect of surgery

Embodiment 1

[0028] Method Example 1: Summer or my country Working Time, use TC4 titanium alloy steel pipe, outer diameter 3.2mm, wall thickness 1.0mm, length due to multi-segment continuous processing, according to the equipment. When the tapered tube of the tungsten steel three-roll concentric mold, the coreless roll-back molding is performed, and when the tapered section itself rotates, the tungsten steel three-roll concentric mold combination is round-trip movement along the length of the tube section; keep it The steel pipe is formed under the rolling oil lubrication conditions of 45 ° C; each time-shaped variable is controlled within the length of each 1 mm, and the radial variation is 0.025 mm. Rolling oil is prepared according to quality: 50% of chlorinated wax wax, 32 # machinery oil 25%, saponified oil 10%, and the remaining 15% is a yellow wine with 12 degrees of alcohol.

Embodiment 2

[0029] Method Example 2 2: Use TC4 titanium alloy steel pipe, 3.2 mm outer diameter, 1.0 mm wall thickness, and length. When the tapered tube of the tungsten steel three-roll concentric mold, the coreless roll-back molding is performed, and when the tapered section itself rotates, the tungsten steel three-roll concentric mold combination is round-trip movement along the length of the tube section; keep it The steel pipe is formed in the rolling oil lubrication conditions of 48 ° C; each of the variables is controlled over the range per 1 mm length, and the radial variation is 0.025 mm. Rolling oil is prepared according to quality: chlorinated wax 46%, 32 # machinery oil 30%, saponified oil 8%, and 16% is a yellow wine for 13 degrees of wine.

Embodiment 3

[0030]Method Example 3: Winter or cold area working hours, use TC4 titanium alloy steel pipe, outer diameter of 3.2 mm, wall thickness 1.0 mm, length. When the tapered tube of the tungsten steel three-roll concentric mold, the coreless roll-back molding is performed, and when the tapered section itself rotates, the tungsten steel three-roll concentric mold combination is round-trip movement along the length of the tube section; keep it The steel pipe is formed in the rolling oil lubrication conditions of 50 ° C; each of the variables is controlled within the length of each 1 mm, and the radial variation is 0.025 mm. Rolling oil is prepared according to quality percentage: 45% of chlorinated wax wax, 35% of 32 # machinery oil, 5% saponified oil, and the remaining 15% is a yellow wine having a 50 degree of wine.

Abstract

The invention provides a TC4 ultrasonic scalpel and a manufacturing method thereof. The TC4 ultrasonic scalpel comprises a taper pipe section and a funnel body, and is characterized in that an external thread is arranged at the large end of the taper pipe section, an internal thread matched with the external thread is arranged at the small-caliber part of the funnel body, an inner hole in the length direction of the taper pipe section is equal to the external taper in the length direction, and the taper ranges from 1: 90 to 1: 150. The operation visual angle is greatly improved, guided wave reflection is avoided, energy loss is reduced, wave bands are more concentrated, and the controllability of a doctor is better; due to the fact that the ultrasonic scalpel head is small in amplitude and extremely high in vibration frequency, extremely high instantaneous acceleration is generated, the TC4 material is combined with the taper pipe structure, all physical performance indexes of the scalpel are more optimized, and when soft tissue cutting is conducted, an acted part can be rapidly cut open, and surrounding tissue of the acted part is not damaged. The micro-acoustic streaming effect, the cavitation effect, the heat effect and the hemostasis effect generated after the full-taper pipe section tool bit makes contact with the human body are better.

Description

Technical field [0001] The present invention relates to medical device techniques, especially a TC4 ultrasonic surgical knife and a method of manufacturing the same. Background technique [0002] Ultrasound surgery is a high-frequency electrical surgical device, mainly used for the cutting of biological tissue and blood vessel closure. Its main mechanism is that the host output electrical signal is used to utilize an electrically extending effect or a magnetostrictive effect. The ultrasonic energy can be converted into mechanical energy to generate high-frequency vibration, and the amplification and coupling of the bell rod will promote the cutter head. And propagate energy to the human body, thereby achieving surgery. Whether it is an attracting ultrasonic surgery or a cutting ultrasonic surgery knife, existing ultrasonic surgery knives are connected by a tapered knife with a straight tube or long straight tube, but these straight tubes are connected When the structure is applie...
