Embodiment 1

[0025]Embodiment 1: A puncture positioner for laparoscopic ultrasound probe surgery, including a body shell 1, a normally closed reed switch 4, a button battery 5 and a laser head 6, the rear end of the body shell 1 is a threaded column structure, and the device The rear end threaded column of the body shell 1 is threadedly connected with the cover base 7, the button battery 5 is arranged at the inner center of the body shell 1, the laser head 6 is set in the front opening of the body shell 1, and the magnet 8 is set in the body The front end of the shell 1, the normally closed reed switch 4 is arranged inside the front end of the body shell 1, and corresponds to the lateral position of the magnet 8, the terminal of the normally closed reed switch 4 is connected to the positive pole of the button battery 5 through a wire, The negative pole of the button battery 5 is connected to the terminal of the laser head 6 through a wire, and the laser head 6 is connected to the normally c...

Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is:

[0029] In this embodiment, the positioning angle adjustment mechanism 2 includes a universal ball joint 21, an adjustment bearing 22, a ring plate 23, an L-shaped support plate 24, an adjustment thread column 25, an adjustment round table 26, a driven bearing 27 and a U-shaped adjustment plate 28. The universal ball joint 21 is symmetrically arranged on the inner wall of the inner ring of the adjustment bearing 22, the rotating ball of the universal ball joint 21 is fixedly connected with the middle part of the outer surface of the body shell 1, and the ring plate 23 is correspondingly arranged on the inner wall of the adjustment bearing 22 On the outer wall of the outer ring, the L-shaped support plate 24 is arranged on the outer arc wall of the circular ring plate 23, and the adjusting thread column 25 is screwed to the vertical plate body of the L-shaped support plate 24, and the outer end surface of the ad...

Embodiment 3

[0034] The difference between this embodiment and Embodiment 1 is:

[0035] In this embodiment, the lifting mechanism 9 includes a printing groove 91, a folding handle 92 and a lifting introduction groove 93. The printing groove 91 is arranged on the rear wall of the cover base 7, and the folding handle 92 is correspondingly arranged inside the printing groove 91. The pull-in groove 93 is arranged on the rear wall of the cover base 7 and is arranged corresponding to the printing groove 91 .

[0036] Specifically, it is set up in this way, because the folding handle 92 is correspondingly arranged in the inside of the printing groove 91, and the lifting guide groove 93 is correspondingly arranged with the printing groove 91, and the personnel folds the folding handle 92 in the printing groove 91 by lifting the introducing groove 93 to carry The hanger body is convenient to carry and store. Since the folding handle 92 is correspondingly arranged inside the printing groove 91, it ...

Abstract

The invention discloses an operation puncture positioner of a laparoscope ultrasonic probe. The positioner comprises a positioner shell, a normally-closed reed switch, a button battery and a laser head, the rear end of the positioner shell is of a threaded column structure, a threaded column at the rear end of the positioner shell is in threaded connection with a sealing cover base, the button battery is arranged in the center of the interior of the positioner shell, the laser head is arranged in an opening in the front end of the positioner shell, a magnet is arranged at the front end of thepositioner shell, and the normally-closed reed switch is arranged in the front end of the positioner shell and corresponds to the transverse position of the magnet. The positioner is simple to operate, firm support is provided, rapid and accurate light spot positioning alignment can be achieved, puncture operation is simplified, two hands are liberated, personnel can carry out positioning punctureoperation with all the heart, the workload of the personnel is reduced, the positioning puncture quality and the positioning efficiency are improved, carrying and storage are convenient, the structural design is reasonable, the occupied space is reduced, laser-assisting positioning light spots are small, and the focusing is good.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary positioning equipment, in particular to a laparoscopic ultrasonic probe surgical puncture positioner. Background technique [0002] Laparoscopic ultrasound is an indispensable real-time image-guided technology for minimally invasive laparoscopic ablation. During the treatment process, the ablation needle needs to penetrate the abdominal wall and be accurately inserted into the special puncture positioning hole at the front end of the probe to achieve precise destruction of the lesion. The surgical puncture positioner in the prior art has many deficiencies, such as cumbersome operation, unable to provide firm support for the body, fast and accurate light spot positioning and alignment, puncture operation is too cumbersome, and it is difficult for the hands to cooperate with each other. Carry out the positioning puncture operation carefully, increase the workload of the operator, reduce t...
