Trocar with automatic suturing function

Abstract

A puncture device with an automatic suturing function comprises a nail bin having a first position and a second position, a nail forming block connected with the nail bin, a sliding block having a third position and a fourth position, first elastic elements exerting first drive force on the nail bin, a second elastic element exerting second drive force on the sliding block, and a puncture rod, wherein when the nail bin is located in the first position, the puncture rod abuts against the first side of the puncture rod in the first direction, when located in the third position, the sliding block abuts against the second side of the puncture rod in the second direction, when the puncture rod is pulled out to a first cocking position, the nail bin moves to the second position under the action of the first elastic elements, and when the puncture rod is completely pulled out, the sliding block moves to the fourth position under the action of the second elastic element to drive the nail forming block to form a suturing nail in the nail bin. After minimally invasive surgery is finished, while the puncture rod (6) is pulled out of the abdominal cavity, an incision can be automatically sutured, so that the surgery working procedures are reduced, and surgery time is saved.

Description

technical field [0001] The invention relates to the field of medical instruments, more specifically, to a trocar with automatic suturing function. Background technique [0002] In minimally invasive human medical surgery, once a lesion is found in the human body, surgery or resection is required. During the operation, the first thing to use is a puncture device, which is a device that pierces the abdominal wall and provides access to the body cavity for other surgical instruments. A surgical instrument belongs to a minimally invasive surgical instrument. [0003] The trocar usually includes a sleeve base as an access channel for other surgical instruments, a conversion cap arranged on the sleeve base, and a puncture rod passing through the sleeve base and the conversion cap. First of all, in order to penetrate the skin, cut the epidermis of the skin with a scalpel, then use the puncture rod to penetrate the skin and enter the body cavity together with the sleeve seat and th...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the prior art has the following disadvantages: after the puncture device is pulled out from the abdominal cavity, manual suturing or suturing with a skin stapler is still required, so the operation is cumbersome and inconvenient, which increases the operation time
