Abstract
Description
Technical Field
[0001] This utility model relates to the field of clasp installation technology, and in particular, to a clasp tooling for processing a multi-channel single-hole laparoscopic surgical trocar. Background Technology
[0002] A multi-channel single-port laparoscopic surgical trocar is a surgical instrument that allows multiple instruments to be introduced simultaneously through a single trocar, significantly reducing surgical trauma. Please refer to [link / reference]. Figure 1 , Figure 2 A multi-channel single-port laparoscopic surgical trocar typically includes a retaining ring 100 and a cover 400. The cover 400 is fixedly mounted on the retaining ring 100. The top of the cover 400 has multiple channels for instrument entry. The cover 400 is made of a soft material (e.g., rubber), and its lower end has an opening. During installation, the lower end of the cover 400 is opened and fitted onto the top of the retaining ring 100, where it is tightened by the elasticity of the cover 400. In actual manufacturing, to improve the reliability and airtightness of the connection between the cover 400 and the retaining ring 100, a retaining ring is usually fitted onto the outside of the bottom of the cover 400 to press the cover 400 firmly onto the retaining ring. The retaining ring is typically formed by two semicircular rings (i.e., a left retaining ring 200 and a right retaining ring 300). During installation, a person holds one semicircular ring with each hand and then presses them together from both sides of the retaining ring to engage the two semicircular rings. This method requires a lot of manpower, and long hours of work can cause hand discomfort. In addition, when the two semicircular rings are snapped together, it is impossible to ensure that the two semicircular rings are in the corresponding state. It is very easy for the two semicircular rings to be misaligned, which will prevent them from being snapped together properly, thus affecting the processing efficiency. Utility Model Content

Detailed Implementation
[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0022] Please see Figures 3-5 This utility model provides a clamping ring fixture for processing a multi-channel single-port laparoscopic surgical trocar, used to install a clamping ring on a fixing ring 100. The clamping ring includes a left clamping ring 200 and a right clamping ring 300 that engage with each other. The clamping ring fixture for processing a multi-channel single-port laparoscopic surgical trocar includes a base 10, and a support seat 11 is protruding from the upper surface of the base 10. The fixing ring 100 is placed on the support seat 11, and clamping rings are respectively installed on the base 10 on opposite sides of the support seat 11. The left drive component 20 and the right drive component 30 are respectively equipped with a left push plate 40 and a right push plate 50. The left push plate 40 and the right push plate 50 can move closer to each other or further away from each other. The left push plate 40 is provided with a left arc groove 410 for placing the left retaining ring 200, and the right push plate 50 is provided with a right arc groove 510 for placing the right retaining ring 300. When the left push plate 40 and the right push plate 50 move closer to each other, they can drive the left retaining ring 200 and the right retaining ring 300 to move closer to each other and engage.
[0023] The multi-channel single-port laparoscopic surgical trocar processing clamping ring fixture of this utility model is used as follows: First, the fixing ring 100 with the cover 400 on top is placed on the support base 11 and kept fixed. Then, the left clamping ring 200 and the right clamping ring 300 to be installed are placed in the left arc groove 410 and the right arc groove 510 respectively. Next, the left driving component 20 and the right driving component 30 are driven to drive the left push plate 40 and the right push plate 50 to move closer to each other. When the left clamping ring 200 and the right clamping ring 300 are... When the two parts come into contact and continue to be squeezed, they will lock into each other. Compared with the traditional installation method of manually squeezing by holding the retaining ring, this utility model is more labor-saving. At the same time, the left retaining ring 200 and the right retaining ring 300 are placed on the left arc groove 410 and the right arc groove 510 respectively, which plays a positioning role for the left retaining ring 200 and the right retaining ring 300, ensuring that the left retaining ring 200 and the right retaining ring 300 can accurately lock into each other when they come close to each other, which greatly improves the installation efficiency.
[0024] The left arc groove 410 includes a bottom wall 411 and a side wall 412. The bottom wall of the left retaining ring 200 is fitted with the bottom wall 411, and the side wall of the left retaining ring 200 is fitted with the side wall 412, thereby ensuring that the left retaining ring 200 is stably placed within the left arc groove 410. The right arc groove 510 includes a bottom wall 511 and a side wall 512. The bottom wall of the right retaining ring 300 is fitted with the bottom wall 511, and the side wall of the right retaining ring 300 is fitted with the side wall 512, thereby ensuring that the right retaining ring 300 is stably placed within the right arc groove 510.
[0025] In a preferred embodiment, the left arc groove 410 is larger than the right arc groove 510. In use, the sidewall of the left retaining ring 200 has a sufficiently large portion that fits against the sidewall of the left arc groove 412, enhancing the structural strength of both ends of the left retaining ring 200 and making it less prone to deformation. Conversely, the sidewall of the right retaining ring 300 has a relatively smaller portion that fits against the sidewall of the right arc groove 512. Therefore, the structural strength of both ends of the right retaining ring 300 is relatively weaker, making it easier for the ends of the right retaining ring 300 to deform under pressure, thereby engaging with the ends of the left retaining ring 200. In this embodiment, both the left retaining ring 200 and the right retaining ring 300 are made of plastic to ensure they can deform under external force and thus engage with each other. Please refer to [link to relevant documentation]. Figure 6 In this embodiment, the left retaining ring 200 has buckles 201 protruding at both ends, and the right retaining ring 300 has grooves 301 recessed at both ends. The buckles 201 and the grooves 301 engage with each other. In addition, the ends of the left retaining ring 200 and the right retaining ring 300 are provided with mutually cooperating inclined surfaces, so that the end of the right retaining ring 300 can be deformed by the cooperation between the inclined surfaces.
[0026] Please also refer to Figure 3 , Figure 5In this embodiment, mounting seats 12 are formed by upward protrusions at opposite ends of the support base 11. Mounting slots 121 are provided on the mounting seats 12. Connecting ears 101 connected to opposite sides of the fixing ring 100 are fitted into the mounting slots 121. Thus, when the lower surface of the fixing ring 100 is in contact with the upper surface of the support base 11, the connecting ears 101 are located in the mounting slots 121. At this time, the fixing ring 100 cannot rotate relative to the support base 11, thus ensuring the relative fixed relationship between the fixing ring 100 and the base 10.
[0027] The left push plate 40 includes a left top plate 41, a left bottom plate 42, and a left connecting plate 43 connecting the left top plate 41 and the left bottom plate 42. The left top plate 41 and the left bottom plate 42 are arranged parallel to each other. A left arc groove 410 is provided on the upper surface of the left top plate 41. The output end of the left drive member 20 is fixedly connected to the left connecting plate 43. In this embodiment, bolts (not shown) are inserted between the left top plate 41, the left bottom plate 42, and the output end of the left drive member 20. Nuts (not shown) are installed at the ends of the bolts to further enhance the connection strength between the left push plate 40 and the left drive member 20.
[0028] The right push plate 50 includes a right top plate 51, a right bottom plate 52, and a right connecting plate 53 connecting the right top plate 51 and the right bottom plate 52. The right top plate 51 and the right bottom plate 52 are arranged parallel to each other. A right arc groove 510 is provided on the upper surface of the right top plate 51. The output end of the right drive member 30 is fixedly connected to the right connecting plate 53. In this embodiment, bolts (not shown) are inserted between the right top plate 51, the right bottom plate 52, and the output end of the right drive member 230. Nuts (not shown) are installed at the ends of the bolts to further enhance the connection strength between the right push plate 50 and the right drive member 30.
[0029] In this embodiment, both the left drive component 20 and the right drive component 30 are cylinders, and the left push plate 40 and the right push plate 50 are respectively connected to the output ends of the two cylinders. In this embodiment, both the left drive component 20 and the right drive component 30 are connected to a mounting bracket 21, which is fixedly connected to the base 10. The connection between the mounting bracket 21 and the base 10 can be a detachable fixed connection method such as snap-fit or bolt connection, and is not limited here.
[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
