Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 4, the puncture channel opener of the present embodiment includes a hand-held portion 1 and an expanding portion 2; the handheld part 1 comprises a left handheld cylinder 1011 and a right handheld cylinder 1012 which are oppositely arranged at the left end and the right end; the expansion part 2 comprises a left expansion rod 21 and a right expansion rod 22 which are respectively connected with the side surfaces of the left holding cylinder 1011 and the right holding cylinder 1012 and have the same length, the left expansion rod 21 and the right expansion rod 22 are in cross connection through a pin 3, and the tail ends of the left expansion rod 21 and the right expansion rod 22 are respectively connected with a right expansion part 24 and a left expansion part 23; the lateral surfaces of the left expansion rod 21 and the right expansion rod 22 are provided with latch teeth 4 which are matched with each other along the horizontal direction.

As shown in FIG. 2, the left and

right expansion parts

23 and 24 are provided with downward tapers, and the left and

right expansion parts

23 and 24 have the same size and shape mirror images, and can be matched with each other to form a conical cylinder after being closed, so as to conveniently enter deep tissues.

As shown in fig. 4, the inner walls of the right and

left expansion portions

24 and 23 are provided with small illumination devices 241 with an image return function and an external power supply, so that the operation position can be conveniently observed, and if an accident occurs, a corresponding scheme can be made in time.

Furthermore, the number of teeth of the latch 4 is at least three, and the latch is small, so that the latch can be very conveniently and easily clamped or clamped, and the target region tissue can be conveniently expanded.

Further, the inner walls of the left hand-held cylinder 1011 and the right hand-held cylinder 1012 are provided with the anti-slip soft pads 102, so that the hand-held parts of the medical staff can be in a comfortable state, and the burden of the medical staff is reduced.

Further, the left hand cylinder 1011 and the right hand cylinder 1012 do not exceed 3cm in length.

The utility model discloses a theory of operation: when operating the deep tissue target, the medical staff holds the hand-held part 1 to combine the left expansion part 23 and the right expansion part 24 of the utility model and arrange the combined parts at the puncture hole or the skin of the target area; the skin is gradually pushed to the deep layer through the small skin incision, when the local part needs to be expanded when the corresponding layer is reached, the latch 4 is smaller, so that the latch 4 can be easily expanded outwards by one tooth position to be continuously locked, a target is exposed, and the next operation is continuously carried out.
