Problems solved by technology

Although such a structure is better than a non-circular structure, due to the friction between the control rod and the channel, when the control rod rotates around its axis, it will inevitably drive the ball to rotate, which does not fundamentally solve the above problems
Therefore, the simulation device has a dead angle in the detection of the above-mentioned motion process, and cannot accurately measure the motion process

Embodiment 1

[0040] An improved endoscope simulation device such as Figure 1-3 As shown, it includes a support 1, a sphere 2 and a control rod 3, the support 1 is an open support, the sphere 2 can rotate freely in the support 1, one end of the control rod 3 is fixed on the diameter direction of the sphere 2, and the control sphere 2 is in the Rotation in the bracket 1, the other end is covered with a handle cover 5, the inner cavity of the handle cover 5 and the section of the control rod 3 are circular, and the handle cover 5 can be pressed relative to the control rod 3 figure 1 Turn and slide in the direction indicated by the arrow. A semicircular arc-shaped slide bar 4 co-centered with the sphere 2 is interspersed in the position of the control rod 3 between the sphere 2 and the handle cover 5, and the two ends of the arc-shaped slide bar 4 are transferred to the outside of the support 1 through the rotating shaft 41 to control Rod 3 can slide relative to it on arc slide bar 4, as f...

Embodiment 2

[0046] Such as Figure 11 It is another endoscope simulation device, and only the main structure at the sphere 2 is shown in the figure. Its structure is similar to that of Embodiment 1, the only difference being that the support 1 of this embodiment adopts a semi-closed structure, and four rotating support platforms 9 are arranged between the inner side of the support 1 and the sphere 2, and the four rotating support platforms 9 are aligned in space. Tetrahedral distribution, the center of gravity of the regular tetrahedron overlaps with the center of the sphere 2, such as Figure 12 As shown in the schematic diagram. This structure greatly improves the stability of the device and provides sufficient space for the control rod 3 to move. In order to improve the structural integration, the orientation sensor 71 of the present embodiment is installed on the top of the rotating support table 9, such as Figure 13 shown.

Embodiment 3

[0048] The structure of this embodiment is further improved on the basis of Embodiment 2, and a manual damping device 101 is added at the position adjacent to the rotating support platform 9, such as Figure 14 shown. Since different parts of the human body tissue have different resistances to the endoscope, practitioners can adjust the rotational resistance of the sphere 2 through usual experience or experienced physicians, so as to practice the force control when using the endoscope. The manual damping device 101 used in this embodiment includes three parts: a handle, a screw and a damping block, and the damping force can be adjusted through the rotation of the screw and the bracket 1, as Figure 15 shown.

Abstract

The invention relates to an improved endoscope simulation device, belonging to the field of analogue simulation exercise equipment of surgical instruments. The technical scheme is that: the improved endoscope simulation device comprises a bracket, a ball body and a control rod, wherein the ball body is installed in the bracket in a free rotation mode; at least two orientation sensors are arranged between the inner side of the bracket and the ball body; one end of the control rod is fixed on the diameter direction of the ball body to control the ball body to rotate; a handle sleeve is sleeved on the other end of the control rod and rotates and slides relative to the control rod;; the inner cavity of the handle cover and the cross section of the control rod are round; a depth sensor and an rotation angle sensor are arranged between the control rod and the handle sleeve; an arc-shaped sliding rod sharing the center with the ball body is inserted on the position between the ball body and the handle sleeve in a relative sliding mode; and two ends of the arc-shaped sliding rod are in through connection on the bracket. In the invention, the defect of the prior art is effectively overcome through the artful design of the handle sleeve and the arc-shaped sliding rod, various actions of tools can be precisely simulated, and the sensor is used for precise measurement. The improved endoscope simulation device has the advantages of simple structure and high simulation degree.

Description

technical field [0001] The invention relates to a surgical instrument simulation training device, in particular to an improved endoscope simulation device with high simulation. Background technique [0002] As a commonly used minimally invasive surgical instrument, endoscopes are used in many types of operations. However, it takes a long training process for surgeons to use endoscope flexibly. Because the familiar process needs to be carried out on living bodies or cadaver samples, there are very few opportunities for medical students and new doctors to practice. There are few, so it usually takes a long time to study before you can use it freely. In order to overcome the defect of practicing in practice, many simulation systems have emerged. With the development of computer technology, simulation systems have been able to combine with simulation image software to achieve very good simulation results. But the existing simulation equipment can't reach the real simulation ef...
