[0002] Laparoscopic surgery is a common surgical method for treating gynecological diseases. Some patients with common gynecological diseases such as pelvic inflammatory disease and uterine fibroids can choose this treatment method. Different sizes of instruments are used in laparoscopic surgery, such as rotary cutters, hemostatic forceps, and dissecting rods, which need to be clamped and fixed by converters.

[0003] A gynecological laparoscopic conversion head, as disclosed in utility model patent application CN221888200U, includes a receiving tube, a control plate, and a limiting tube. The receiving tube has an inlet at its top, and the control plate has a circular hole. The bottom end of the receiving tube communicates with the circular hole, and the circular hole communicates with the top end of the limiting tube. The bottom end of the limiting tube has an outlet. Several rigid limiting blocks are mounted on the control plate, symmetrically distributed around the center of the control plate. The bottom ends of the rigid limiting blocks are detachably connected to the control plate, and soft limiting blocks are mounted on the top ends of the rigid limiting blocks, connecting to the rigid limiting blocks. This design allows for controlled and tight connection with instruments of different diameters.

[0004] However, the above technical solution has the following shortcomings: When using the above solution, the spacing of multiple sets of limiting blocks cannot be adjusted simultaneously, and instruments of different specifications cannot be quickly clamped. At the same time, when the limiting blocks are adjusted, there are gaps, which cannot guarantee the sealing when they are in contact with the instruments. Therefore, we propose a laparoscopic quick conversion connector. Utility Model Content

[0005] The purpose of this invention is to provide a laparoscopic quick conversion connector to solve the problems mentioned in the background art, such as the inability to simultaneously adjust the spacing of multiple sets of limiting blocks, the inability to quickly clamp instruments of different sizes, and the gaps in the limiting blocks during adjustment, which cannot guarantee the sealing when in contact with the instruments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laparoscopic quick conversion connector, including a support tube, an adjustment seat disposed on the support tube, and a limiting tube disposed on the lower side of the adjustment seat. An adjustment ring is provided on the adjustment seat by means of a threaded rotation, and multiple sets of limiting mechanisms are also provided on the adjustment seat in a ring arrangement.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-3 as well as Figure 6 This utility model provides a technical solution: a laparoscopic quick conversion connector, including a support tube 3, an adjustment seat 2 set on the support tube 3, and a limiting tube 4 set on the lower side of the adjustment seat 2. An adjustment ring 1 is set on the adjustment seat 2 by screw rotation. The adjustment seat 2 is also provided with a limiting mechanism arranged in a ring. Specifically, the limiting mechanism is provided with 6 or 8 sets.

[0033] The limiting mechanism includes a limiting clamp 106, which is disposed in a receiving groove 107. The receiving groove 107 is disposed on the inner wall of the adjusting seat 2. A crossbar 104 is disposed on one side of the limiting clamp 106. One end of the crossbar 104 passes through the guide opening and extends into the groove 101. The groove 101 is disposed on the outer surface of the adjusting seat 2. A wedge 103 is disposed on one end of the crossbar 104, which moves with the adjusting ring 1 as it rotates. An arc-shaped chamfer 102 is disposed on one side of the inner surface of the adjusting ring 1. The arc-shaped chamfer 102 fits against the outer surface of the wedge 103. When the adjusting ring 1 rotates, it can synchronously drive 6 or 8 sets of wedges 103 to move.

[0034] First, insert the required laparoscopic instruments through the support tube 3 and out through the limiting tube 4. Then, rotate the adjusting ring 1. The adjusting ring 1 rotates and moves on the adjusting seat 2. The rotation of the adjusting ring 1 drives the arc-shaped chamfered part 102 to rotate and move. When the arc-shaped chamfered part 102 is in contact with the wedge block 103, as the adjusting ring 1 moves, it drives 6 or 8 sets of wedge blocks 103 to move simultaneously. The movement of the wedge blocks 103 drives the crossbar 104 to move simultaneously. The movement of the crossbar 104 drives 6 or 8 sets of limiting clamps 106 to move simultaneously, thereby bringing 6 or 8 sets of limiting clamps 106 into contact with the surface of the laparoscopic instruments and clamping and fixing the laparoscopic instruments. By adjusting the 6 or 8 sets of limiting clamps 106 simultaneously, different laparoscopic instruments can be clamped and fixed quickly in one piece.

[0035] Furthermore, a return spring 105 is sleeved on the crossbar 104. One end of the return spring 105 is connected to the crossbar 104, and the other end of the return spring 105 is connected to the guide port. When the wedge block 103 drives the crossbar 104 to move, the crossbar 104 compresses the return spring 105. When the adjusting ring 1 is rotated in the opposite direction, the return spring 105 drives the crossbar 104 to return to its original position and automatically releases the instrument.

[0036] Furthermore, one side of the limiting clamp 106 is arc-shaped, which increases the contact area between the limiting clamp 106 and the instrument surface. A sealing gasket 113 is provided on one side of the limiting clamp 106 so that the sealing gasket 113 is in contact with the laparoscopic instrument surface to ensure clamping and sealing.

[0037] Furthermore, an upper limit part 21 and a lower limit part 22 are respectively provided on both sides of the outer surface of the adjusting seat 2, which can position the moving position of the adjusting ring 1.

[0038] As a specific embodiment of this application, please refer to Figures 4-7 An adaptive adjustment component is provided between adjacent limiting clamps 106. The adaptive adjustment component includes an arc-shaped mounting groove 108, which is respectively provided on one side surface of the limiting clamp 106. A positioning block 109 is provided in the arc-shaped mounting groove 108, and an arc-shaped adjustment plate 110 is provided on one side surface of the positioning block 109. One end of the arc-shaped adjustment plate 110 is slidably provided in the arc-shaped mounting groove 108 of the adjacent limiting clamp 106. When the 6 or 8 sets of limiting clamps 106 move, the arc-shaped adjustment plate 110 moves automatically and adjusts the clamping diameter. At the same time, it can fix the laparoscopic instruments and ensure the overall clamping seal.

[0039] When the 6 or 8 sets of limiting clamps 106 move synchronously, the positioning plate simultaneously drives the 6 or 8 sets of arc-shaped adjusting plates 110 to move simultaneously. The movement of the arc-shaped adjusting plates 110 ensures that the 6 or 8 sets of limiting clamps 106 always maintain a closed circular structure. By having the arc-shaped adjusting plates 110 and the limiting clamps 106 fit against the surface of the laparoscopic instruments, the laparoscopic instruments are clamped in a closed manner, ensuring clamping stability and sealing.

[0040] Furthermore, guide sliders 112 are provided on both sides of the arc-shaped adjustment plate 110. The guide sliders 112 are slidably disposed in the guide groove 111. The guide groove 111 is disposed on both sides of the arc-shaped mounting groove 108. When the arc-shaped adjustment plate 110 moves, it drives the guide sliders 112 to move in the guide groove 111 and guides the movement of the arc-shaped adjustment plate 110.

[0041] In this application, the surface of one side of the arc-shaped adjustment plate 110 has the same curvature as the surface of the limiting clamp 106, which ensures the flatness of the arc-shaped adjustment plate 110 and the limiting clamp 106, thereby further improving the sealing performance during clamping.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
