Problems solved by technology

However, the length of the traditional puncture device is fixed, about 10 cm, and cannot adapt to the thickness of the abdominal wall independently. During the operation, the surgical observation field of view is affected, the operating distance is restricted, and the puncture device itself is easy to come out or go too deep, etc., which affects the smoothness of the operation. to prolong the operation time
In order to shorten the operation time more effectively, adapt to the needs of the operation, achieve minimally invasive physical and psychological, and further expand the concept of minimally invasive surgery, it is required to "intelligent" the laparoscopic related instruments, so as to achieve more convenient operation and More effectively shorten the operation time; while the existing equipment cannot meet these conditions at the same time, and cannot provide more "intelligence"

Abstract

The invention relates to an adaptive puncture outfit. The adaptive puncture outfit comprises a sleeve which is axially provided with a puncture hole and a puncture awl which arranged in the puncture hole of the sleeve in a penetrating mode and can motion axially relative to the sleeve, the sleeve is composed of a sleeve head and a sleeve body, the sleeve body comprises a straight-pipe-shaped connecting part connected to the sleeve head and a bending part which is of a petal-shaped structure and can be separated and bend outwards, and the bending part is composed of multiple pipe petals which are distributed in a circumference mode with a sleeve axial lead as a center; the inner walls of the pipe petals are provided with dovetail guide grooves, the dovetail guide grooves are internally provided with coil springs, and the periphery of the puncture awl is provided with multiple dovetail guide rails which are coordinated with the dovetail guide grooves of each pipe petal in a one-to-one correspondence mode and are used for fitting the pipe petals on the puncture awl. In the adaptive puncture outfit, the bendable sleeve of a petal-shaped structure is adopted, the sleeve is fixed on skin tissue, and besides, the adaptive puncture outfit can adapt to the thickness degree of different types of enterocoelia skin tissue of different patients, is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an adaptive puncturer. Background technique [0002] The gradual consensus of minimally invasive concept in medical treatment has made minimally invasive surgery, especially laparoscopic surgery, widely popularized. However, laparoscopic surgery must establish an operation channel through a trocar, which includes pneumoperitoneum channel, camera channel and Surgical channel, that is, through this type of channel, the abdominal cavity can be inflated to establish a certain surgical space, and the camera can be placed in the abdominal cavity to perform video projection on the display screen, and then use long-handled instruments to perform various surgical operations through other same channels, so as to To achieve the purpose of reducing the incision. However, the length of the traditional puncture device is fixed, about 10 cm, and cannot adapt to the thickness of the...
