Description

Endoscope clamping assembly and its holder

This case is an endoscope clamping assembly, especially an endoscope clamping assembly that can adjust the position, angle and direction of an endoscope and can firmly clamp the endoscope. This case further discloses a holder for the endoscope holding assembly.

Minimally invasive surgery has many advantages such as small wounds, no damage to normal tissues around the surgical site, and quick recovery. Therefore, it has become the mainstream of surgical operations and gradually replaces 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 endoscopic. Due to the high price of Da Vinci minimally invasive surgery equipment, which is not affordable by ordinary hospitals, the general minimally invasive surgery still relies on endoscopy.

Generally speaking, the endoscope includes an endoscope equipped with a lens to obtain images, and an endoscope used to introduce at least one instrument to perform surgery. That is to say, take the image endoscope as an example. After entering the human body, the position, angle and direction must be adjusted to obtain the image required by the surgical site. It is best to avoid vibration or displacement. Therefore, the endoscope was initially supported by manpower, but because manpower cannot be durable and stable, the relevant industry has developed an endoscope clamping assembly dedicated to clamping the endoscope. The endoscope clamping assembly can be roughly divided into two types: a robot (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 doctor’s foot, instead of The dexterity that comes with hand control. In particular, the robot-type endoscope clamping assembly is expensive and has a risk of failure, so that it cannot be popularized.

Although the mechanical endoscope holding assembly has a cost advantage, a holder of the endoscope holding assembly cannot be close to a puncture guide sleeve for the endoscope to penetrate, so that the After the endoscope is clamped by the holder, it is not easy to adjust the angle, direction, and depth position. The reason 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. The distance between the instrument and the puncture guide sleeve causes the arm of force between the two to be longer, so that a slight adjustment at the clamping part will cause a larger swing at the end of the endoscope, which is not conducive to the depth, angle and the Adjust the direction of the endoscope image.

Therefore, a better way for the endoscope is to manually adjust the endoscope, and then move an adjustable joint support device of the endoscope holding assembly and the holder to an appropriate position, and open the holder.

As shown in Figures 8 to 10, which show the relevant diagrams of the second embodiment of the clamper using the tightening ball, this embodiment is another modified implementation of the first embodiment, and compared to the first embodiment. The same reference numerals (symbols) of an embodiment are used to indicate the same components. Since this embodiment shares many common components with the first embodiment, only the differences between the two are described in detail later.

The difference between this embodiment and the first embodiment lies in the structure of the tightening ball 24. As shown in FIG. 8, the tightening ball 24 of this embodiment axially has a rod hole for the endoscope 3 to be inserted into. 241, and a plurality of grooves 242 are radially spaced apart on the circumferential surface of the middle and lower section of the tightening ball 24, so that a clamping claw piece 243 is formed between two adjacent grooves.

As shown in Figures 9 and 10, when the correct image of the endoscope 3 is obtained, the medical staff only needs to lock the knob 26 so that the upper pressing plate 22 and/or the lower pressing plate 23 are subjected to an axial pressure. For example, the upper pressure plate 22 moves toward the inclination angle of the upper surface 212a after receiving the axial pressure, and causes the upper ball groove 221 and the lower ball groove 231 to produce radial compression on the tightening ball 24, and This causes the clamping claw pieces 245 to deform and retract to clamp the endoscope 3, thereby forming a positioning and locking effect.

As shown in Figures 11 to 12, which show the relevant diagrams of the third embodiment of the tightening ball used in the holder, the same reference numerals (symbols) in this embodiment are used to indicate the same as the first embodiment. Since this embodiment shares many common components with the first embodiment, only the differences between the two are described in detail later.

As shown in FIG. 11, the tightening ball 24 includes an upper hemisphere 244 and a lower hemisphere 245 that are axially butted, and an upper shaft hole 241a of the upper hemisphere 244 and a lower shaft hole 241b of the lower hemisphere 245 together form a shaft hole 241.

The top surface of the lower hemisphere 245 is provided with an abutting oblique ring 241e that communicates with the lower rod hole 241b and abuts on the pressing oblique surfaces 241d, so that the upper hemisphere 244 and the lower hemisphere 245 are butted to form an installation in The tightening ball 24 between the upper ball groove 221 and the lower ball groove 231. The upper rod hole 241a and the lower rod hole 241b are for the endoscope 32 to pass through.

As shown in FIG. 12, when the correct image of the endoscope 3 is obtained, the medical staff only needs to lock the knob 26 so that the upper pressing plate 22 and/or the lower pressing plate 23 are subjected to an axial pressure, such as After receiving the axial pressure, the pressing plate 22 moves toward the inclination angle of the upper surface 212a, and urges the upper ball groove 221 and the lower ball groove 231 to radially compress the tightening ball 24, so that the Each of the pressing inclined surfaces 241d of the clamping claw piece 241c is deformed and retracted along the abutting inclined ring 241e to clamp the endoscope 3, thereby forming a positioning and locking effect.

As shown in Figure 13, it shows another embodiment of the endoscope clamping assembly used in an operating table. The operating table 4 is further connected to a gantry type bracket 5, and the bottoms of a pair of uprights 51 on both sides of the bracket 5 are respectively mounted on a horizontal guide 41 corresponding to both sides of an operating table 4 by a first clamp 52, and The main ball shaft 123 of the adjustable joint support 1 is combined with a second clamp 54 on the top of the two vertical rods 51 and a cross rod 53. The pair of vertical rods 51 use the first clamp 52 to adjust the longitudinal height, The main ball shaft 123 uses the second clamp 54 to adjust the left-right distance, and then adjusts the adjustable joint support 1 to approach a patient's surgical position.

Therefore, through the implementation of this project, the effect of the gain is that the tightening ball is made of Teflon or silicone material resistant to high temperature disinfection. When subjected to proper pressure, a ball shaft joint is formed between the upper and lower ball grooves of the upper and lower pressing plates; when the knob is locked, the upper and lower pressing plates apply axial direction to the tightening ball Pressure and radially squeeze the tightening ball, resulting in deformation and inward shrinkage of the tightening ball, so as to clamp and restrain the endoscope, and at the same time the tightening ball is also fixed, thereby The depth position, angle and direction of the endoscope are fixed at the same time, so as to obtain the stable image effect required by the operation.

Furthermore, the various embodiments of the holder of the present invention should be close to the puncture guide sleeve when in use, so that slight adjustments at the clamping part will not cause a large swing at the end of the endoscope, which is beneficial to the inner end. The adjustment of the depth position, angle and direction of the mirror is a great structure that has never been seen before in the endoscope clamping assembly.

The disclosure in this case is one of the preferred embodiments, and any partial changes or modifications that are derived from the technical ideas of the case and can be easily inferred by those who are familiar with the art do not deviate from the scope of the patent right of the case.
