Problems solved by technology

However, the existing needle insertion device has problems such as complex structure, single needle insertion mode of the needle insertion mechanism (lack of a fast needle insertion mode, and the patient feels strong puncture pain), and the overall weight of the device is large and inconvenient to control. It is difficult to meet the application requirements of the puncture needle robot

preparation example Construction

[0058] Provide the preparation method of protective coating of the present invention below, it may further comprise the steps:

[0059] 1) Add emulsion, polyolefin elastomer, polytetrafluoroethylene, ultra-fine glass wool, polyethylene foam cotton and solvent into the mixer and mix well, control the speed at 500-1200rpm, and control the temperature at 60-150°C , stirring for 2-5h;

[0060] 3) Add glass microspheres, nano-carbon fibers, nano-alumina powder, nano-silicon carbide powder and coupling agent in sequence, and stir for 1-3 hours;

[0061] 4) Add a curing agent and continue to stir for 30-90 minutes to obtain a protective coating.

[0062] The prepared protective coating is sprayed on the outer surfaces of the upper and lower flanges 72, the inner surfaces of the clamping groove 114 and the guide groove 115, and then dried to obtain a protective coating.

Abstract

The invention discloses an arc-shaped rail RCM needle insertion device for a minimally invasive surgical puncture robot. The device comprises an arc-shaped rail, a needle insertion mechanism arrangedon the arc-shaped rail, an arc-shaped motion driving mechanism and a rotary driving mechanism, wherein the rotary driving mechanism drives the arc-shaped rail, the whole needle insertion mechanism andthe arc motion driving mechanism on the arc-shaped rail to rotate; and the arc motion driving mechanism drives the needle insertion mechanism to move along the arc shape on the arc-shaped rail, and thus a needle insertion point position of a puncture needle is fixed through the combination of the two motions, and a needle feeding angle can be adjusted arbitrarily, so that a needle insertion posture is adjusted, and accurate puncture needle insertion is realized. Through the arrangement of an elastic needle assembly, rapid needle insertion of the puncture needle can be realized, and pain feeling of a human body can be relieved; and the needle can be smoothly and slowly inserted through the driving assembly until a focal point.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an arc guide rail RCM needle insertion device for a puncture robot in minimally invasive surgery. Background technique [0002] Minimally invasive surgery is the use of slender rod-shaped surgical tools inserted into the body through tiny incisions on the surface of the body for surgical operations. Compared with traditional open surgery, it can reduce surgical incisions and surgical scars, shorten recovery time, reduce bleeding and complications, etc. It can be seen that minimally invasive surgery has incomparable advantages over open surgery, so it has been widely accepted. Favored by patients and doctors, minimally invasive techniques have been applied in many clinical fields. [0003] However, the current minimally invasive surgery is basically performed by experienced physicians, but the reality is that there are limited experienced physicians, the duration of the punctur...
