Description

Endoscope holding assembly and its holder

technical field

The present invention relates to an endoscope clamping assembly, in particular to an endoscope clamping assembly capable of firmly clamping the endoscope after the position, angle and direction of an endoscope can be adjusted. The present invention further discloses a holder for an endoscope holding assembly.

Background technique

Minimally invasive surgery has many advantages such as small wound, no damage to normal tissues around the surgical site, and quick recovery. Therefore, it has become the mainstream of surgery and gradually replaced the traditional open surgery. Minimally invasive surgery requires the help of equipment, advanced ones such as Da Vinci minimally invasive surgery, and the most common is endoscopy. Due to the high price of the equipment for Da Vinci minimally invasive surgery, it is not affordable for ordinary hospitals, so the general minimally invasive surgery still relies mainly on endoscopy.

Generally speaking, the endoscope includes an endoscope for obtaining an image with a lens, and an endoscope for introducing at least one instrument to perform surgery. Taking the imaging endoscope as an example, after entering the human body, it needs to adjust the position, angle and direction to obtain the desired image of the surgical site, and it is best to avoid vibration or displacement. Therefore, the endoscope is initially supported by manpower, but because the manpower cannot be durable and stable, those skilled in the art have developed an endoscope clamping assembly specially used for clamping the endoscope. The endoscope clamping assembly can be roughly divided into two types: a robotic endoscope clamping assembly and a mechanical endoscope clamping assembly.

Although the robot-type endoscope clamping assembly can effectively achieve the purpose of adjusting the position, angle and direction, the robot-type endoscope clamping assembly is controlled by the user, such as the foot of the doctor, without the The dexterity of hand control. In particular, the robotic endoscope clamping assembly is expensive and has a risk of failure, so it cannot be popularized.

Although the mechanical endoscope clamping assembly has a cost advantage, a holder of the endoscope clamping assembly cannot be close to a puncture guide sleeve for the endoscope to pass through, so that the After the endoscope is clamped by the holder, it is difficult to adjust the angle, direction and depth position. The reason for this is that after the endoscope enters the human body through the puncture guide sleeve, the endoscope uses the puncture guide sleeve as a support point to adjust the depth angle and the direction of the endoscope image. Due to the distance from the puncture guide sleeve, the force arm between the two is relatively long, so that a slight adjustment in the clamping part will cause the end of the endoscope to have a larger swing, which is not conducive to the depth, angle and the inner diameter of the endoscope. Orientation adjustment of the sight glass image.

Therefore, the preferred way of the endoscope is to manually adjust the endoscope, then move an adjustable engagement support device of the endoscope clamping assembly and the holder to a proper position, and open the clamping The endoscope can be clamped and fixed; but when the adjustable joint support device is released, it is not good due to its own multi-joint structure and the limitation of the angle, plus the weight of the adjustable joint support device. control, so that the adjustable engagement support device still deviates after locking, and is not easy to correct.

Therefore, how to overcome the aforementioned shortcomings and make the traditional low-cost mechanism-type endoscope clamping assembly have better operability is a common problem faced by those skilled in the art.
