Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a modular endoscopic instrument fixation base. Background Technology

[0002] Laparoscopic surgery is a procedure performed using a laparoscope and related instruments, inserted through a puncture site on the body surface to replace the surgeon's glasses and hands. It offers advantages such as safety, minimal trauma, faster postoperative recovery, less bleeding, shorter hospital stays, less surface scarring, and fewer adhesions. A fixation base is typically used to secure the laparoscopic instruments.

[0003] Currently used modular laparoscopic instrument fixation bases mostly rely solely on placement slots to secure the instruments. This method offers poor stability, making it easy for the instruments to detach from the base during use, thus affecting the placement of the instruments and hindering subsequent use. Furthermore, most of these bases are one-piece designs, lacking modular assembly and disassembly capabilities, which makes it difficult to replace the base later and reduces its practicality.

[0004] In summary, this utility model solves the problems in the background art by designing a modular endoscopic instrument fixing base. Utility Model Content

[0005] The purpose of this invention is to provide a modular endoscopic instrument fixation base to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A modular endoscopic instrument fixation base includes an instrument body and a fixation base disposed below the instrument body. A counterweight is disposed at the bottom of the fixation base, a mounting post is fixedly disposed at the top of the counterweight, a locking block is disposed at the top of the mounting post, mounting blocks are fixedly disposed on the outer side of the fixation base respectively, mounting holes are formed on the top surface of the mounting blocks, a placement groove is formed on the top surface of the fixation base, and a fixing mechanism is disposed between the placement groove and the instrument body. The fixing mechanism includes a clamping plate, a guide plate is fixedly installed on the top of the clamping plate, and guide posts and guide springs are fixedly installed on the outer side of the clamping plate respectively.

[0021] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A modular endoscopic instrument fixing base includes an instrument body 1 and a fixing base 2 disposed below the instrument body 1. A counterweight 201 is disposed at the bottom of the fixing base 2, a mounting post 2011 is fixedly disposed at the top of the counterweight 201, a locking block 2012 is disposed at the top of the mounting post 2011, mounting blocks 202 are fixedly mounted on the outer side of the fixing base 2, a mounting hole 2021 is opened on the top surface of the mounting block 202, a placement groove 3 is opened on the top surface of the fixing base 2, and a fixing mechanism 4 is disposed between the placement groove 3 and the instrument body 1. Specifically, the mounting blocks 202 are located on the left and right sides of the fixing base 2, and the positions of the mounting blocks 202 and the mounting posts 2011 are correspondingly set. The outer surface of the mounting posts 2011 is fitted with the inner wall of the mounting holes 2021. The shape and size of the locking blocks 2012 are consistent with those of the mounting posts 2011. The locking blocks 2012 rotate eccentrically with the top of the mounting posts 2011 through a rotating shaft, and the bottom surface of the locking blocks 2012 is in frictional contact with the top surface of the mounting blocks 202. In this embodiment, the mounting column 2011 is mainly used to make contact with the mounting hole 2021, realizing the contact between the mounting block 202 and the counterweight block 201. The locking block 2012 is mainly used to rotate eccentrically with the mounting column 2011, causing the locking block 2012 and the top of the mounting block 202 to form a friction self-lock, thereby achieving the modular assembly of the fixed seat 2 and meeting the replacement needs of subsequent personnel.

[0022] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The fixing mechanism 4 includes a clamping plate 401, a guide plate 402 is fixedly installed on the top of the clamping plate 401, and a guide post 403 and a guide spring 404 are fixedly installed on the outer side of the clamping plate 401 respectively. Specifically, the front and rear ends of the placement groove 3 extend to the front and rear sides of the fixing base 2 respectively, and the placement groove 3 is equidistant from the top surface of the fixing base 2. The clamping plate 401 is mirrored from the inner central axis of the placement groove 3, and elastic pads are provided on the opposite sides of the clamping plate 401. The top surface of the guide plate 402 is inclined. The end of the guide post 403 away from the clamping plate 401 is attached to and penetrates the inner wall of the placement groove 3 and extends inward. The end of the guide spring 404 away from the clamping plate 401 is fixed to the inner wall of the placement groove 3. In this embodiment, the guide plate 402 is mainly used to guide the instrument body 1, causing the instrument body 1 to move between the clamping plates 401. The guide spring 404 is mainly used to provide elastic support for the clamping plate 401. The guide post 403 is mainly used to ensure that the clamping plate 401 moves smoothly laterally, thereby making the clamping plate 401 and the instrument body 1 in stable contact, thus meeting the fixation requirements of the endoscopic instrument.

[0023] The working process of this utility model is as follows: When using a modular endoscopic instrument fixing base, the fixing base 2 is first moved, causing the fixing base 2 to bring the mounting block 202 closer to the mounting post 2011. During the approach process, ensure that the mounting post 2011 and the mounting hole 2021 are in engagement contact until the mounting post 2011 and the mounting hole 2021 are fully engaged. At this point, the locking block 2012 can be rotated eccentrically. As the locking block 2012 rotates, its bottom gradually generates frictional contact force with the top surface of the mounting block 202, thereby achieving the locking of the mounting block 2012. 02 performs a mechanical self-locking function, which meets the modular installation requirements of the fixed base 2. Then, the instrument body 1 is moved so that it contacts the inclined surface of the guide plate 402, causing the instrument body 1 to slide into the clamping plates 401. The compressed guide spring 404 applies pre-pressure to the clamping plate 401, causing the clamping plate 401 to drive the guide column 403 to slide against the inner wall of the placement groove 3. The opposing side surfaces of the clamping plate 401 are in close contact with the instrument body 1, thus achieving the function of fixing the instrument body 1 and meeting the needs of the user.

[0024] 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.
