Description

Technical Field

[0001] This utility model relates to the field of anastomosis technology, and in particular to a positioning and steering device for a laparoscopic anastomosis. Background Technology

[0002] Anastomosis devices are medical devices used to replace traditional manual suturing. Due to advancements in modern technology and improvements in manufacturing techniques, the anastomosis components of these devices are often designed to be rotatable to enhance their flexibility. A knob mechanism controls the rotation of the anastomosis components. This mechanism typically incorporates gears, allowing adjustment of the rotation range through the meshing of these teeth. However, this design choice can lead to issues such as insufficient rotational precision, poor maneuverability, and instability. Utility Model Content

[0003] The present invention aims to solve the above-mentioned defects and provide a positioning and steering device for a laparoscopic anastomosis device.

[0004] In order to overcome the defects in the background technology, the technical solution adopted by this utility model to solve its technical problem is: a positioning and steering device for a laparoscopic anastomosis device, including a rotating body, a transmission shaft is arranged axially, and several positioning grooves are equally spaced around the rotating body.

[0005] The positioning and fixing mechanism is used to position the rotating body. It contains a ball bearing and a thrust spring for pushing the balls on the ball bearing into the positioning groove.

[0006] Further improvements include the positioning and fixing mechanism comprising four fixing plates, the fixing plates being arranged in pairs, each pair of fixing plates being connected by fixing clamps, the arc-shaped portion of the fixing clamps perfectly fitting and embedding into the annular groove opened on the rotating body, the two pairs of fixing plates being joined together to form a cylindrical structure with the arc-shaped plates on the fixing plates joined together, the ball bearings and the thrust spring being arranged inside the cylindrical structure.

[0007] Further improvements include the ball body comprising a ball and a retainer, wherein the retainer has a receiving groove for accommodating the ball.

[0008] Further improvements include providing at least one clamp.

[0009] The beneficial effects of this utility model are: in this design, the ball body and the dividing groove achieve precise angle adjustment, which makes the operator more precise in controlling the rotation range of the knob device and the operation more convenient. In addition, the positioning and fixing mechanism positions the rotating body to ensure the stability of the rotating body during rotation. This design has a simple structure and is easy to assemble.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0017] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a laparoscopic anastomosis positioning and steering device includes a rotating body 5 with a drive shaft 6 axially arranged thereon. A knob is installed at the end of the drive shaft 6. Rotating the knob drives the rotating body 5 to rotate. Several equidistant positioning grooves 11 are opened on the rotating body 5 in the circumferential direction.

[0018] The positioning and fixing mechanism is installed inside the anastomosis device to position the rotating body 5 and thus restrict the movement of the rotating body 5 in the three degrees of freedom of the X-axis, Y-axis and Z-axis. Inside it is a ball bearing and a thrust spring 10 for pushing the ball bearing 3 on the ball bearing to embed into the dividing groove 11. When the rotating body 5 is rotated, the ball bearing 3 is embedded into the adjacent dividing groove 11 to achieve indexing adjustment.

[0019] In this embodiment, the positioning and fixing mechanism includes four fixing plates 1. The fixing plates 1 are arranged in pairs, and each pair of fixing plates 1 is connected by fixing clamps 7. The arc-shaped part on the fixing clamp 7 perfectly fits the annular groove 4 opened on the rotating body 5 and is embedded therein to ensure that the rotating body 5 is positioned when rotating. The two pairs of fixing plates 1 are joined together so that the arc-shaped plates 9 on the fixing plates 1 are joined together to form a cylindrical structure. The ball bearing and the thrust spring 10 are arranged inside the cylindrical structure.

[0020] In this embodiment, the ball body includes a ball 3 and a retainer 2. The retainer 2 has a receiving groove 8 for accommodating the ball 3, and the ball 3 can rotate in the receiving groove 8 to ensure that the ball 3 can be embedded in the positioning groove 11, thereby achieving steering positioning.

[0021] In this embodiment, at least one clamp 7 is provided to further position the rotating body 5 and ensure the stability of the rotating body 5 during rotation.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
