Application Expansion Of Centralized Procurement To Accelerate Domestic Ultrasonic Scalpel Is Expected To Rapidly Increase Volume

Ultrasonic knife  is a high-energy focused ultrasonic instrument, which utilizes the electrostrictive effect (the phenomenon of elastic deformation of the dielectric in the electric field) or the magnetostrictive effect (the geometric size of the magnetic substance is reversible due to the change of the external magnetic field during the magnetization process. Changes), convert ultrasonic electric energy into mechanical energy, through the amplification and coupling of the horn, push the cutter head to work, and radiate energy to the local tissue of the human body, so as to carry out surgical treatment.

 

Ultrasound scalpel has the advantages of less damage, faster postoperative recovery, and higher accuracy, and is currently widely used in clinical practice. In recent years, thanks to the improvement of the level of medical technology, the market size of my country’s ultrasonic scalpel has continued to grow. At the same time, under the promotion of the centralized procurement policy, the domestic ultrasonic knife is expected to gradually achieve overtaking on the curve.

 

Wide variety of uses

 

At present, ultrasonic scalpel is widely used in clinical practice, mainly for laparoscopic surgery, gynecological surgery, pediatric surgery, urological surgery, and orthopedic surgery for specific orthopedic structures (such as joints, spine), etc.

 

The ultrasonic knife system is mainly composed of piezoelectric transducer, horn and cutter head. Among them, the piezoelectric sheet of the piezoelectric transducer is fixed by a pre-tightening screw, which can convert the electrical energy of the power supply into vibration mechanical energy; the shape of the horn has various types such as exponential, ladder, catenary and composite type. The ultrasonic energy is concentrated on a small area to amplify the displacement or speed of mechanical vibration; the cutter head can cut or emulsify human tissue by radiating sound energy, and suck it out of the body using negative pressure.

 

In surgery, the ultrasonic knife is used as an ultrasonic dissection device to destroy, break down or coagulate tissue, especially tissue with a high water or fat content. The device produces a cavitation effect on the tissue it comes in contact with, enabling simultaneous cutting and coagulation of tissue and blood vessels up to 5 mm in length. The active blade of the ultrasonic knife can vibrate more than 55,000 times per second, which makes it generate frictional heat when it comes into contact with human tissue, which causes the protein in the tissue to denature and become a kind of coagulation to seal the blood vessels, and the operation is not easy to damage in this way. surrounding blood vessels and nerves. Therefore, the medical ultrasonic knife is also called “ultrasonic cutting hemostatic knife”.

 

There are various types of ultrasonic scalpels, mainly including soft tissue  ultrasound scalpel, ultrasound bone scalpel, phacoemulsification suction scalpel, ultrasound debridement scalpel, etc. Among them, soft tissue ultrasonic scalpel and ultrasonic osteotome are more representative in clinical applications.

 

The working principle of the soft tissue ultrasonic knife is mainly based on the cavitation effect and mechanical vibration effect. The knife head contacts the human tissue at an ultra-high vibration frequency, so that the moisture in the tissue is rapidly vaporized, the hydrogen bond of the protein in the tissue is broken, and the protein is denatured and coagulated. So as to achieve cutting, coagulation and hemostasis. At present, the soft tissue ultrasound scalpel is mainly used in abdominal surgery, and is gradually applied in other departments such as thyroid and breast surgery, urology and so on.

 

The working principle of the ultrasonic bone knife is mainly based on the mechanical vibration effect. The knife head can generate hundreds of thousands of times of gravitational acceleration, which can quickly smash the bone tissue; at the same time, its action range is only a few hundred microns, which will not cause damage to adjacent tissues. cracks and damage, so precise cuts can be achieved. At present, ultrasonic osteotome is mainly used in dentistry and oral and maxillofacial surgery, and is gradually expanding to spine surgery.

 

Rapid expansion of market size

 

The global ultrasonic scalpel market is huge. According to data released by Frost & Sullivan, the global ultrasonic scalpel market has grown from US$2.32 billion in 2016 to US$2.87 billion in 2020, and is expected to reach US$4.63 billion in 2025.

 

Frost & Sullivan data also shows that the market size of my country’s ultrasonic scalpel has grown from 1.022 billion yuan in 2016 to 2.513 billion yuan in 2021, with a compound annual growth rate of 19.71%; among them, the market size of domestic brands has grown rapidly. , has grown from 12 million yuan in 2016 to 359 million yuan in 2021 (see the figure for details).

 

Although the size of my country’s ultrasonic scalpel market is expanding rapidly, due to the relatively high technical threshold of the industry, the market share of my country’s ultrasound scalpel is mainly occupied by foreign brands at this stage. At present, the products of multinational companies occupy a dominant position in the ultrasonic scalpel market in China. It is worth noting that, with the support of policies, relevant domestic enterprises are expected to usher in good development opportunities.

 

Centralized procurement to promote port substitution

 

In recent years, with the continuous advancement of the reform of centralized procurement  of medical consumables, the centralized procurement of ultrasonic scalpels has covered many provinces, and the price of selected products has dropped significantly.

 

In July 2020, Fujian Province launched a batch of centralized procurement of medical consumables, among which the selected products of ultrasonic knife medical consumables dropped by an average of 40.77%.

 

In November 2021, a centralized procurement alliance composed of 16 provinces and cities including Guangdong, Shanxi, and Inner Mongolia will carry out centralized procurement of ultrasonic tool heads. The pre-purchased quantity of this centralized procurement is about 440,000, and the maximum product price (2,500 yuan) has been set, involving 27 selected companies, and the product selection rate is as high as 77.14%. The average price of the selected products was reduced by 70.11%, and the highest price reduction was 93%. There were 20 selected products of ultrasonic cutter heads below 1,000 yuan, of which the price of many cutter heads was as low as 500 yuan, and the lowest price was 450 yuan. It is worth noting that most of the domestic brands have been active in this centralized procurement, and are committed to broadening the market for domestic products.

 

It is believed that with the in-depth advancement of the centralized procurement of ultrasonic scalpels and the entry of more capital to support the development of domestic brands, domestic ultrasound scalpels will achieve further volume, and domestic brands are expected to usher in the opportunity to overtake on curves.
