Embodiment 1

[0060] The structure of the portable medical puncher of the present embodiment is as Figure 1-5 As shown, the puncher includes a base 2 with a groove 201 and a handle 1 with a punching head 5, the groove 201 is located in the middle of the upper surface of the base 2, and runs through the front end and the end of the base 2; The groove 201 is a semicircular surface groove, and the inside of the groove 201 is used to place the medical catheter 9 that needs to be punched, which plays the role of positioning the catheter 9, and prevents the punching head 5 from pressing the catheter 9 when the hole is punched. out of shape.

[0061] The end of base 2 is movably connected with the end of handle 1 by bearing pin 3, so that handle 1 can rotate up and down with bearing bearing 3 as a shaft. When the base 2 is fixed and the handle 1 turns upwards, the handle 1 drives the punching head 5 away from the conduit 9 at the groove 201, and when the handle 1 turns downwards, the handle 1 dr...

Embodiment 2

[0075] The structure of the portable medical puncher of the present embodiment is as Figure 6-7 As shown, in order to avoid the trouble of disassembling and assembling the punching head 5 each time, improve the punching efficiency, and strive for precious medical time, the present embodiment installs a circular guide rail 11, and the punching head 5 is detachably fixed on the circular guide rail by a buckle. 11 lower surface, and can move with the ring guide rail 11. Ring guide rail 11 is located at the place ahead of handle 1 front end, and a punching head 5 at the end of ring guide rail 11 is the punching head that punching uses, and all the other punching heads are positioned at the place ahead of the punching head that this uses.

[0076] When in use, the punching head on one side of the circular guide rail 11 moves from front to rear in turn, and moves to the punching head at the end of the circular guide rail 11 to punch holes. After punching, the punching head continue...

Embodiment 3

[0083] The using method of the portable medical puncher of embodiment 1 comprises the following steps:

[0084] (1) Choose a steel wire galvanized spring with a free height of 6mm and install it between the handle and the base; the hole to be punched is 0.3mm in diameter, choose a punching head with the corresponding diameter, and install it at the front of the handle;

[0085] (2) Disinfect the hole punch as a whole;

[0086] (3) Put the medical catheter into the groove, and adjust the position of the catheter to be punched directly below the punching head;

[0087] (4) Insert the sterilized magnetic rod into the catheter, fix the catheter, turn on the magnetic field of the electromagnetic coil, and put the sterilized magnetic sheet into the punching head;

[0088] (5) Adjust the position of the spring on the first slide rail and the second slide rail, and fix the top and bottom of the spring;

[0089] (6) Press the handle downward, when the bottom of the punching head touc...

Description

technical field [0001] The invention belongs to the technical field of medical catheter punching equipment, and in particular relates to a portable medical punching device. Background technique [0002] With the advancement of modern medical technology, surgical treatment is gradually developing towards miniaturization and minimal invasiveness, so as to minimize the trauma and pain caused to patients. Interventional therapy is a minimally invasive treatment using modern high-tech means. Under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments are introduced into the human body to diagnose and locally treat lesions in the body. The application of digital technology in interventional therapy expands the doctor's field of vision. With the help of catheters and guide wires, it can directly reach the lesion, with small trauma, fast recovery and good effect. It is the development trend of future medicine. In interventional tr...
