High-frequency minimally invasive surgery instrument for vascular melt closed cutting

Abstract

The invention discloses a high-frequency minimally invasive surgery instrument for vascular melt closed cutting, which comprises a claw beam assembly with the diameter of 10-12mm / 5-8mm and a control grip assembly, wherein a fast plugging mechanism is arranged between the claw beam assembly and the control grip assembly; the claw beam assembly can be exchanged; the claw beam assembly comprises clamping forceps, a fork frame, a claw beam, a lock drum / conductive ring, a jaw steering thumb wheel, a clamping opening / closing drive mechanism, a cutter drive mechanism and a disposable control mechanism; and the control grip assembly comprises a grip housing, a clamping forceps control mechanism, a cutter control mechanism, a current / signal switch and conduction device, a claw beam assembly exchange / lock mechanism, and a cutting safety mechanism. The high-frequency minimally invasive surgery instrument has the beneficial effects that the disposable using method for exchanging the claw beam is adopted; the purposes of reducing the surgery cost and preventing a patient from being threatened by cross infection are achieved, and the high-frequency minimally invasive surgery instrument is positively significant for the development of the minimally invasive medical career in China.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a minimally invasive surgical instrument for high-frequency blood vessel closure and cutting. Background technique [0002] Minimally invasive surgery is an emerging medical technology. Minimally invasive surgery has the advantages of less bleeding, fewer complications, less pain, less risk, and faster recovery for patients. Minimally invasive surgery has a high degree of recognition in China. More than 1,100 hospitals across the country are carrying out this surgery, and it has also been widely recognized by patients. [0003] However, at present, the instruments for this type of minimally invasive surgery are all imported from developed countries in Europe and the United States, which are expensive and are all disposable. Last year alone, the minimally invasive surgical equipment and instruments purchased, used, and consumed in my country reached 50 billion yuan . ...

AI Technical Summary

Problems solved by technology

[0004] The minimally invasive surgical instruments for high-frequency vascular closure and cutting currently used in China are mainly produced in the United States, Germany, the United Kingdom, and France. The clamp rod and handle of these products cannot be separated, and the clamp rod assembly cannot be replaced to reduce the cost of use; this device Although it is clearly defined as a one-time use product, because there is no one-time use restriction mechanism in the design, coupled with the high price, all domestic hospitals are reusing it; Between the pliers handles, the opening angle of the clamping forceps is too large, and it is easy to slip during operation; when the jaws are opened, the edges and corners of the two pliers handles will protrude from the pliers rod, which is easy to cause accidental injury to the exposed organs during the operation; this structure often The exposed wires are brought out of the wire slot, and the wires are often stuck in the piercer and cannot be pulled out, and the wires are repeatedly bent to affect the quality; the design and processing of some components are complicated and difficult, and the requirements for manufacturing equipment are high, which is not conducive to reducing costs

[0005] Minimally invasive surgical instruments not only have a wide variety but also involve multiple industries, requiring high equipment and complex processing. It is a multidisciplinary, knowledge- and capital-intensive high-tech industry with high entry barriers and high added value.
