Problems solved by technology

1 Tumors farther away from the anus (>5cm) need to be implanted with an intracavitary particle implanter, which is easy to fall off, and the curative effect is average
2 For tumors close to the anus (< 5cm), seeds are implanted with a puncture needle under direct vision, the depth cannot be controlled, and there are many complications

Embodiment Construction

[0014] Such as figure 1 The hand-touch particle implanter shown includes an outer protective sheath 1, a puncture trocar 2 and a guide rod 3. The outer protective sheath 1 is a tapered sleeve whose front end is smaller than the rear end, and the front end of the outer protective sheath 1 is rounded. horn.

[0015] The guide rod 3 is inserted into the puncture trocar 2, the outer protective sheath 1 is set on the outside of the puncture trocar 2, the outer protective sheath 1, the puncture trocar 2 and the guide rod 3 are relatively slidingly arranged, and the puncture trocar 2 The upper slide is provided with a puncture positioning slider 5 behind the outer protective sheath 1 . The outer surface of the puncture trocar 2 is provided with a length scale with a 0 scale on the needle tip.

[0016] A derivation and positioning slide block 7 located behind the puncture trocar 2 is slidably arranged on the guide rod 3 . The rear end of outer protective sheath 1 is fixedly connect...

Abstract

The invention discloses a hand-touch type seed implantation apparatus comprising an outer protective jacket, a puncture trocar and a guide rod. The guide rod is inserted into the puncture trocar, the outer protective jacket sleeves the puncture trocar, the outer protective jacket, the puncture trocar and the guide rod slide relatively, and a puncture positioning slider located in the rear of the outer protective jacket is arranged on the puncture trocar slidably. The puncture depth is preset through the puncture positioning slider, the point of the puncture trocar is covered by the outer protective jacket when entering the colorectum, fingers and the rectums of operation patients are prevented from being punctured, when the puncture trocar contacts with the tumor, the puncture trocar is driven to be inserted into the tumor tissue to reach the preset depth, then seeds are pushed into the tumor tissue through the guide rod, the seeds can be implanted to the preset depth accurately, and accordingly seed implantation depth can be controlled. The operation method is simple and safe to use.

Description

technical field [0001] The invention relates to a hand-touch particle implanter. Background technique [0002] Seed implanters are chemical or radioactive seeds (eg: I 125 ) into the tumor tissue to kill or inhibit the tumor. Due to the special location of rectal tumors, it is difficult to complete seed implantation with ordinary seed implanters. [0003] Currently, there are two methods for seed implantation in colorectal tumors. 1 Tumors farther away from the anus (>5cm) need to be implanted with an intracavitary particle implanter, which is easy to fall off, and the curative effect is average. 2 For tumors close to the anus (< 5cm), implant seeds with a puncture needle under direct vision. The depth cannot be controlled and there are many complications. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a relatively safe hand-touch particle implanter which can control the depth of implantation.
